FOREWORD I N submitting this Chute and Equipment Bulletin to the trade, the thought is to offer a Bulletin which, taken in connection with our Mixer Bulletins, will enable the contractor or engineer to lay out a COMPLETE PLANT without referring to several catalogues and handbooks; to order the complete plant from one company and thereby hold one company responsible for the correct working of the whole outfit. In the selection, design, and manufacture of Concrete Equipment, the RANSOME CONCRETE MACHINERY COMPANY occupy a most unique position. They were not only the pioneers in the field, but their wide experience as contractors and engineers especially qualifies them as manufacturers of construction equipment. On the RANSOME CONCRETE MACHINERY COMPANY’S FORCE today are men who have had years of experience in the installation and operation of some of the largest construction plants, and all designs are passed upon by them before they are submitted to the trade. In this Bulletin, not only the details of the various pieces of equipment are given to show the simple, sturdy, practical construction, but many plans and views of com¬ plete plants are shown, to enable the engineer or con¬ tractor to pick out a plant, or a combination of plants, that will best fit the particular needs of his job. THE RANSOME ENGINEERING DEPARTMENT, backed by years of actual construction experience, is at all times ready to serve contractors or engineers in suggesting and laying out plants, for which service there is no charge. 3 200-FOOT TOWER WITH 500 FOOT OF CHUTE. BUILDING BRIDGE ON SOUTHERN RAILWAY SYSTEM 4 Ransome Concrete Machinery Co. CONCRETE DISTRIBUTION BY CHUTES HE DISTRIBUTION and handling of concrete by chutes has been in use so long that practically every construction man is familiar with the method. Late in 1909 the RANSOME CONCRETE MACHINERY COMPANY designed a portable Chuting Plant for use on the cotton warehouses in New Orleans; and this plant was followed a few months later by a portable car plant which put in the foundations for the by-products coke ovens of the Tennessee Coal, Iron & R.R. Co., at Ensley, Ala. Since that time the progress in this method of placing concrete and equipment for same have been greatly improved by them. Today there are two general types of plants: the BOOM Plant, which may be either stationary or portable, and the CONTINUOUS LINE Plant, which is usually stationary. The TRIPOD method of supporting complete Chuting Plants has been gradually abandoned for the more flexible BOOM Plant, although the tripods are still used as an auxiliary to the Boom and Continuous Line Plants. On many jobs all three types of plants are combined in one. A study of the plans and views shown later in this bulletin will give a clear and comprehensive idea of what can be done with the various types of plants separately and in combination. SLOPE There has been much theoretical discussion on this, but actual practice has shown that it is safest to stick to a slope of one vertical to three horizontal. The only variations from this almost standard slope are in the use of fine gravel concrete, where a slope of one to four is practical, and for concrete in which the coarse aggregates are stone or slag in. or larger, where it is advisable to use a slope of one vertical to two and one quarter horizontal. There are two facts that have become established in the chuting of concrete: First, that only well-mixed concrete can be handled. Second, that concrete with an excess of water cannot be handled successfully. Thus the use of chutes is an assurance of good concrete. SHAPE For years both theory and practice demonstrated beyond ques¬ tion that the flow of materials in conduits of all kinds depends upon the amount of friction between the material and the surface of the conduit, and that the shape, giving the minimum of wetted surface for any given volume of material carried, insures the greatest carry¬ ing capacity. The cross-section of the RANSOME CHUTE conforms to this condition. A series of experiments showed con¬ clusively the superiority of this shape, not only as to rate of flow but, what is of equal importance, as to separation. SIZE The size of the chute has been another point on which there has been much speculation. In the early stages of this method of handling concrete there was the greatest diversity of opinion, 5 CHUTING PLANT, INCLUDING STEEL TOWER AND SWIVEL HEAD CHUTE SUSPENDED FROM CABLE, ON DODGE BROTHERS’ PLANT, DETROIT, MICHIGAN 6 Ransome Concrete Machinery Co some experienced engineers claiming 6 in. chute was ample, while there have been instances where a chute of 16 in. or more has been thought to be necessary. Actual practice has shown that the smaller chutes have ample capacity to carry the concrete turned out by even the larger mixers when there are no large aggregates; but the trouble with the smaller chutes has been that very often large aggregates work into the concrete and cause trouble. Another fact that was not taken into consideration at the first was that it is not practical to operate a chute flowing full of concrete. For years, in the designing of Hoist Buckets some leeway was usually allowed between the capacity of the bucket in the amount of actual concrete it would handle and in its water measure. This allowance has averaged about 3 in. In designing the new Ransome Chutes the thought has been constantly kept in mind that best results will be obtained if the chutes are operated at about two thirds full. The shape of the Ransome Chutes is such that when they are two thirds full they give as large a capacity, if not larger, than any other standard chute on the market. The width of 12 in. is ample to handle as large an aggregate as should be used in a one-yard mixer and the depth of 10 in. gives ample clearance under the cross bracing, so that there is not any tendency for an occasional large stone to hit the cross bracing and cause the concrete to pile up and overflow at this point. The carrying capacity of a chute depends upon the rate of flow, and on this point there is the greatest difference of opinion. One authority gives the rate of flow at 75 to 100 ft. per minute, while another gives it at 250 ft. per minute. Careful observation of Ransome engineers in the field show that the average of these two is at least safe. Taking this average, a RANSOME CHUTE flowing one half full continually will carry 1.6 cu. yds. of concrete per minute. Another point that has been brought out very forcibly in many experiments conducted by Ransome engineers is that the size of the Hopper Heads has a most important bearing on the capacity of a Chute Plant. There is a change in direction of the flow of concrete at the Hopper Head which momentarily checks the rate of flow, and consequently a piling up of the concrete takes place until the original velocity can again be acquired. To take care of this checking of the rate of flow, Ransome Hopper Heads have been increased 25% in depth. MATERIAL USED The body of the Ransome Chutes is made out of No. 14 Gauge HIGH CARBON STEEL, which averages 30% stronger than ordinary blue annealed sheets and 100% harder. This additional strength permits of the construction of a chute lighter in weight, to carry a given load. The 48 ft. Swivel Head Trussed Chute, shown loaded with 40 lbs. of sand per foot and three men, registered the same deflection as another chute constructed of ordinary blue annealed Ransome Concrete Machinery Co. sheets, weighing 33 } 4 % more when loaded with the same load. The saving in weight is a great advantage both in erection and operation of plants. On a 96 ft. Open Boom Plant it means at least 100 lbs. less weight to be handled by the men moving the lower end of the second chute. The additional hardness gives that much additional resistance to abrasion and reduced wear under the action of the flowing concrete; and a Ransome Chute constructed of No. 14 Gauge HIGH CARBON STEEL has as much, or more, resistance to wear than a chute made out of No. 12 Gauge Ordinary Blue Annealed Sheets. DETAILS OF CONSTRUCTION Standardization, Interchangeability of Parts, and Unit Construction are demanded in all industrial lines today. This principle has been carried out in Ransome Chutes. In general, as previously stated, Chutes are of two kinds — SWIVEL HEAD and CON¬ TINUOUS LINE — and the same units are used in the construction of both. This means that existing plants can be added to, or repairs made to damaged parts at any time. If one section of a Ransome Chute should become damaged it is only necessary to order a new part, and when it arrives simply loosen a few bolts, slip it in place, and tighten up the bolts again. Due to changes in plans, it sometimes becomes necessary to change the type of plants ordered for a particular job; if the chutes are not constructed on the Interchangeable Unit Part System, this may necessitate the purchase of additional chutes. On one job several Ransome Boom Plants were purchased. A change in the plans of the building necessitated changing the Boom Plants to Continuous Line Plants. The contractor wired for a few Flexible Joints, and in a short time the Swivel Head Chutes were changed to Continuous Line Chutes. The economy in time and money in Interchangeable Unit Construction was clearly proven in this instance. Naturally, where the concrete drops from one chute into another, there is greater wear than in the center of the chute, where the concrete simply flows along. In a Ransome 48 ft. Swivel Head Chute there are three 16 ft. Trough Units. Each end of each Trough Unit can be placed at the Hopper Head end, which gives six times the wear at this point as compared with a chute not built on the Interchangeable Unit Part System. The advantage of this construction is self-evident in shipping and dismantling chutes. NINE Interchangeable Units make up the greater part of any run of Ransome Chutes. The base of the system is a 16 ft. Trough Unit (Item No. 101) cross braced by five plates securely riveted and having a connecting flange riveted to each end. 8 Ransome Concrete Machinery Co.

The view of a complete Swivel Joint shows the large Hopper Head which takes care of the momentary checking of the velocity, due to the change of direction, and also the Swivel Hook located out¬ side the Splash Hood, which is an advantage, as a clear path is given the concrete.

RANSOME COUNTERWEIGHT CHUTES are made in two lengths 32 ft. (Item No. 134) and 48 ft. (Item No. 135). The 32 ft. section will carry a 32 ft. Swivel Head Section and the 48 ft. section is strong enough to carry a 48 ft. Swivel Head Trussed Section at its lower end. This means that a Ransome Counterweight Chute is stronger and naturally heavier than a chute that will carry only the load of concrete within itself. On practically every job instances arise where it is advantageous to carry another section of chute on the lower end of the counter¬ weight section. It will always be an economy for the con¬ struction man to buy a counterweight chute strong enough to do this. Ransome 48 ft.

Ransome 48 ft. Swivel Head Boom Chute Item No. 138 RANSOME SWIVEL HEAD BOOM CHUTES have been built on so many special orders during the season of 1919 that it has seemed best to list them as Standard Equipment. They are made in two lengths — 32 ft. (Item No. 137) and 48 ft. (Item No. 138). They serve the same purpose as the Open Wooden Boom Plants and it is often cheaper to install them — the economy depending on whether it costs less money to build the tower 15 ft. higher than it does to purchase Open Wooden Boom Irons and build an Open Wooden Boom. It should always be borne in mind that in the installation of a Swivel Head Boom Chute, the distance from the boom seat end of the chute when the bin is at its highest point to the top of the tower must be at least 30 ft. The boom chutes are double trussed and are equipped with liners to insure ample stiffness. At the upper or hopper head end of the boom chute a special SWIVEL BRACKET (Item No. 139) is attached. Ransome Two-Way Hopper Line Switch. Item No. 140 RANSOME TWO-WAY HOPPER LINE SWITCH (Item No. 140) is used under the Bin where it is desired to run two lines of Continuous Chutes in two different directions.

There are no catches or trips and the bucket operates quickly in a direct vertical lift. If the hoisting engineer carelessly pulls the bucket above the dumping point, no damage will result either to bucket or tower. The bucket will automatically discharge at any panel in the tower, by simply removing the front guide from that particular panel and placing the dumping blocks at the right point. The bucket operates equally well in wooden or steel towers.

The straight back brings the center of the pivot close to the tower, and reduces to the minimum all strains on the tower from the kick-back of the Boom or the Boom Chute. The Straight Back Bins can be mounted on a sliding frame which for wooden towers can be built on the job as easily as the tower itself. When so mounted and used either alone or in con¬ junction with a Boom Chute, it can quickly be moved from one tower panel to another. When used with the Open Boom Plant a similar sliding frame is constructed for carrying the boom seat, the two frames are tied together by chains, and the whole Open Boom Plant can be quickly moved up or down the tower. All bins should have from one and one-half to two times the capacity of the hoist bucket used in conjunction with them.

RANSOME STEEL TOWERS strike the right medium between the tower which is too heavy for practical purposes and the tower which is so light that it cannot be held from twist¬ ing. Errors in both directions have been quite frequent in the construction field in the past. These towers are built in 15 ft. lengths which experience has proven is an economical and practical length both in shipping, assembling, and dismantling. Two types of towers are offered — Light Towers for Bin Load only and Heavy Towers for Booms, Long Line of Chutes or Sliding Frames. A contractor can readily decide which tower is best suited for his average job, but if he is doing a variety of work the Heavy Tower will be economical in the long run. It has not seemed best to offer a steel tower for the 12 cu. ft. Hoist Bucket, as it is a question whether the expense of a steel tower would be justified on a job which would not require a hoist bucket larger than this. Steel towers for the 66 cu. ft. Buckets are built on special orders.

From the bin it is distributed to the forms by cars. On certain classes of bridge and pier work these cars have saved the installation of an expensive cableway.

They can be used to handle the muck from the excavation, to charge the mixer or to distribute the concrete. There is hardly a concrete job where this car could not be kept busy from start to finish.

They are much more easily worked than a spade, particularly in narrow forms, as a direct vertical up and down motion is all that is required with the Beam Tamper, while a spade requires a lateral movement. Shipping weight, 8 lbs. RANSOME SLICE TAMPERS are used to work the concrete around the reinforcing bars and break up air pockets. Shipping weight, 10 lbs. RANSOME FLOOR TAMPERS force the large aggregates down and leave only the mortar on top to be finished. By the use of a Floor Tamper the top of a floor or wall can be finished without making a special batch of mortar and the one-course floor is much stronger than the two-course. Shipping weight, 26 lbs. RANSOME CONCRETE AX is a tool for “hammer dressing” a concrete surface and has been in use for years. A workman can dress about 10 sq. ft. of surface per hour, provided the concrete has not set too hard. Shipping weight, 3 x /i lbs. 44 Ransome Concrete Machinery Co.
