E Ti cI OTIS SKIP HOISTS AUTOMATIC OPERATION OTIS ELEVATOR COMPANY OFFICES IN ALL PRINCIPAL CITIES OF THE WORLD OTIS SKIP HOISTS AUTOMATIC OPERATION For the Speedy and Efficient Handling of Coal, Ashes and Similar Materials in Gas Plants, Central Sta- tions, Mining Plants, Factories, Etc. The Otis automatic push button controlled Skip Hoist as illustrated and described on the fol- lowing pages is intended to meet a growing demand for high grade reliable apparatus for raising various materials in bulk, such as coal, ashes, etc., and automatically delivering them at a higher level. One of the chief causes contributing to the demand for automatic apparatus of this nature is the increasing scarcity of manual labor, which results in a demand for equipment that will reliably perform the work previously done by manual methods. A prime requisite of automatic apparatus for hoisting materials is reliability, and this has always been the first consideration in the design and selection of the apparatus and material used in building Otis Automatic Skip Hoists. ' > ; | > ' - ‘ ee Particularly must the hoisting machine and controlling apparatus be of the most rugged and correct design, as any failure to properly perform their functions would result, in most cases, in costly delays, and thus defeat the purpose for which the apparatus was installed.

The usual skip hoist control system also is nearly identical with that used on certain classes of regular freight and passenger elevator installations. Next in importance to the question of relia- bility and proper design in the minds of the operating force of any plant is the consideration of the facility and quickness with which they can secure spare parts. Since we use standard ele- vator apparatus on skip hoist installations and due to the fact that Otis Service offices are located in all the important cities and towns of the United States, as well as in the principal cities in other parts of the world, it is always possible to secure promptly any renewal parts which may be required, as spare parts for standard elevator machines and controllers are kept in stock at all of our Service offices. Otis Skip Hoists may be divided into two classes according to whether the bucket for carry- ing the load travels vertically or on an incline. Both vertical and incline hoists may be equipped with a single hoisting bucket, which may or may not require a counterweight, or with two hoisting buckets running on separate tracks, the one acting as the counterweight for the other. For the duties generally found in handling coal, ashes, etc., in Manufacturing Plants and 0S SS SS SS ~“\ et SSS i Ce SS SSS SSS SESS SSS SSS SS eS | / | | <> WY vA | y She ~~ Central Power Stations, it is, as previously explained, our practice to use standard elevator hoisting machines. These can be located either overhead or at ground level, adjacent to the hoist- way. [he usual machine consists of a single or double drum (according to whether a single or double skip arrangement is used), a worm gear reduction, an electrically-released, spring-applied shoe brake, and a motor, all of these parts being mounted on a heavy cast iron base plate to pre- serve alignment. The illustration below clearly shows the arrangement. -Where an extra heavy load is to be handled at slow speed an additional speed reduction is frequently employed, consisting of a pinion engaging with an internal cut gear mounted on the hosting drum. This arrangement is shown in the illustration on page 7. ae V aie, VS ae Se, i ne j= we =f aaa = Se \ Ae ANE a iS ae en 44 Otis Alternating Current Hoisting Machine.

The control system generally furnished is an important feature of Otis Skip Hoist apparatus, as its action is entirely automatic. The operation is by means of three push buttons marked “Up”, ~Down™ and ‘Stop’. These are mounted in a box, as illustrated on page 8, and can be located wherever most convenient. When the bucket has received its load the attendant presses the “Up” button which causes the machine to start, and from this point the operation is entirely automatic. The machine accelerates to full speed, the bucket rises to the upper level, and at the proper point the machine slows down and the bucket travels into the dumping position, where on single skips it stops and automatically remains for a pre-determined interval which is sufficient to allow the material to be entirely discharged from the bucket. The machine then automatically starts in the down” === ane? ae. = am. se SF A a ase ft Vv } y \ Vw Vana ee ae 5 A ete testes 7 pte os é atte. = —— Poo test direction and continues in operation until the buck- et reaches the lower level and automatically stops in the loading position. A pressure of the “Stop” button at any time during the travel of the bucket will cause the machine to come to rest. If the “Up” button is then pressed, the bucket will con- tinue in its normal cycle as above described, and if the “Down” button is pressed, the bucket will return to the loading position at the bottom. In the case of a double skip hoist, when the ascending bucket reaches the dumping position the machine remains stationary until it is again started by the operator at the loading point, he having in the meantime attended to the loading of the other bucket. The advantages of an automatic control sys- tem such as above described are very great. The attendant is enabled to go ahead with other work as soon as he has pressed the button which starts the hoist. |The push button control is entirely independent of the class of labor used, since the stopping and dumping are not sgsiaeeai upon manipulation of the oper- Z ating button, hand rope or switch, as is the case with non-automatic control sys- tems. It is possible to elimi- nate an operator entirely by arranging the bucket so that it is loaded auto- matically, and when a Push Button Box showing ; Up, Down, and Stop predetermined load has Control Buttons rave reve (—<——= 4 + { Front View. isms (7: | ‘ sao WIND Back View.

The machine then starts, and the | bucket ascends, automatically closing the gate on : the loading chute in passing, and continues upward ‘s to the dumping position, then dumps, descends, : opens the loading gate in passing, stops, and re- NI loads, this continuous automatic operation ceasing only when the supply of material is not sufficient t to fill the bucket. | Push Button Control may be ‘- furnished as an auxiliary method of operation. Yj This system can be used with either single or M double skips. The bucket usually furnished for vertical skip : hoists, either of the single or double skip type, is +e made of heavy steel plates reinforced with structural NJ shapes, and provided with two cams symmetrically ( located on each side of the bucket. These cams vy are made of channels or angles properly shaped, : and riveted to the bucket. The bucket is sup- - ported in a steel frame or sling by means of two ; trunnions, and is held in an upright position and A guided during its travel by means of two steel. yj brackets bearing against angle iron guides. These ; guides, which are fastened to the sides of the vk hoistway, control the travel of the bucket. As : Hey, | the bucket approaches the upper limit of the travel the cams engage with a pair of rollers 71 4 mounted securely at the sides of the hoistway. i les] The action of the cams and rollers causes the il Wt bucket to swing from the vertical position until RA it reaches an angle at which the material contained V7 nw) in the bucket can freely slide into the chute, m1 14) hopper or other receptacle provided for this pur- } Ne ' J H Section of Tower Showing Bucket, Cams, Trunnions, Brackets, Guides, etc. NS a EIS SIE SY \ K pose. At the position where the bucket starts to swing, the angle iron guides are cut so that the brackets can pass through the guides and permit the bucket to swing. The usual arrangement of bucket, cams, rollers, etc., is shown in the illus- tration on page II. Where the material is to be hoisted on an incline, the bucket is equipped with four flanged wheels as illustrated in the diagram on page 14. These wheels usually run on standard light weight railway tracks and by the use of double treads on one pair of wheels and additional tracks at the dumping point, the bucket is dumped without the use of the cams and rollers which are necessary on the vertical type of hoist. The hoistway for the travel of the bucket may be a steel tower, a concrete hatch or well-way or any other desired form of construction. p WI <=) SS = SEH SS StS tS - On single bucket installations the question of whether a counterweight is required is one depending entirely upon the load and_ speed conditions. For light loads and slow speeds it is usually unnecessary to install a counterweight. —<—— — + <= & Bee k= <4 : SSS SS ee tS) SSS SSS eS SS tS Arranged for Vertical Hoisting. -= 7 Z } 10 o a, ee & ® ff pe 5 wp as 46) SS 8.9 = Qs ee co Ww Os Se atau 2 0 2s O is 3) 6 S 22 ox 3 a) Q. wi a cal cd Typical Layout of Otis Automatic Push Button Skip Hoist Arranged for Hoisting on an Incline. a StS IE oS SSS SOME TYPICAL INSTALLATIONS OF OTIS SKIP HOISTS IN MANUFACTURING PLANTS, COAL AND COKE PLANTS, GAS, ELECTRIC LIGHT AND POWER STATIONS = aie 7 sly, = Y Y JSS J BNERY LIBR COWMBIA US Se =: ee ial eae SSeS VS | | | 0 SSS a === ==> == ‘4siopy dryg uoqyng ysng onewo ny SAO jo uoNeR][eisuy djo;duio7+y yRordA 7 Otis Automatic Skip Hoist handling hot calcium carbide in a Manufacturing Plant. 18 Otis Skip Hoist in Manufacturing Plant, Showing Bucket near Dumping Position. 19 Otis Skip Hoist in Manufacturing Plant.
