r Page One YOUR INITIAL COST IS YOUR FINAL COST Detail drawing showing end and side view of the 20th Century Economy Scaffolding. We wish to call your attention to the putlog shown on the right which is explained in detail on Page 3. The 1 / 2 - inch point on the end of the putlog shown at the upper right-hand corner drops in back of the face brick, tieing the putlog securely to the wall. The Ledger Board Clamp, explained on Page 5, not only prolongs the life of the ledger board, but is a preventive of unnecessary accidents. The Pole Splice Clamp, illustrated on Page 6, has been proven to save at least 70 per cent over the old method of splicing poles. There have been over 20,000 of these clamps placed in the field during the past six months. The Splice Pole, shown on the left of this sectional view, is not only used for exterior scaffolding but has been extensively adopted by decorators and plasterers for interior of churches, halls, theatres, etc. This Splice Pole is shipped complete ready for use. Starter Poles are eight feet long and intermediate or two splice poles are 11 feet long. < Page Two CUT DOWN THAT OVERHEAD EXPENSE The above cut is the drawing on the opposite page shown in perspec¬ tive. You will note that no braces or stays are shown as they are not necessary on the 20th Century Economy Scaffolding. This is borne out by the pictures on pages 9, 10, 11, 12, 13 and 14 showing the scaffolding in actual use. The putlog will not injure, deface or pull the wall in any way. These facts are proven on pages 15 and 16. Consider the simple construc¬ tion, easily erected and dismantled, and so built that no mistakes are possi¬ ble, thus minimizing the possibility of accidents through faulty erection. Page Three PUTLOGS FOR EXTERIOR POLE SCAFFOLDING Previous to the invention of the putlog shown below, it was a common sight to see unsightly putlog holes in new buildings, but that day has practi¬ cally passed, for today the contractor who leaves unsightly holes in the brick walls, lays himself open to charges of using antiquated methods. The patented putlog not only makes a much stronger scaffolding, but it eliminates at least 90 per cent of the rack or cross stays, and leaves no disfigurement in the masonry. The putlog is constructed with a clincher plate which is inserted into the end joint. A half inch point on the end of the clincher plate drops in back of the face brick. The outer end of the put¬ log sets on top of the ledger board, fastened to the upright pole—this gives the scaffolding an in and out stay which is much stronger and safer than any amount of rack staying that may be used. Each putlog is tested to carry three times the maximum weight ordinarily placed on a platform. The Double Pole Scaffolding Has Been Proven Obsolete Since the Patented Putlog Has Been Obtainable The putlog is not only a money saver to the contractor, but it is ex¬ tensively indorsed by the leading architects in the Eastern States because it does not deface the wall in any way.

Page Five A SIMPLIFIED LEDGER BOARD CLAMP This ledger clamp is used not only to prolong the life of the ledger board, but also to safe¬ guard the contractor from any unnecessary accidents. They not only speed up the erection and dismantling of the scaffolding, but can easily be applied by one man. When a clamp tested to carry 8000 pounds is used, the contractor is assured he is taking every precaution to prevent any unnecessary accident through the faulty nailing of ledger boards. By the adoption of this clamp you do not destroy the ledger boards. Outside of weather discolorations, the ledgers are in the same condition as when originally purchased. This clamp is very easily applied. The ends of the clamp are burred so as to prevent losing the nuts. In applying the clamp, simply unscrew the face plate and release same from the lock plate; place clamp in position around upright pole and ledger board with the lock plate at the top, so that the face plate will cross the ledger board on a 45 degree angle. Place the face into the lock plate and tighten up nuts, until the gripping teeth are firmly imbedded into the ledger board.

Note that the clamp is made in one piece so there is no danger of losing any part of it. The clamp is made sufficiently strong of heavy steel and rugged construction so that it will carry the maximum load placed on the scaffolding. Each clamp is assembled by hand and properly coated to prevent rust. We can assure any contractor a saving of at least 70 per cent in labor and material each time this clamp is used. Isn’t this saving worth consider¬ ing ? Clamps are made in two sizes for 3x4 and 4x4 poles. Page Seven INSIDE FOLDING PUTLOG HORSE The inside folding putlog horse takes the place of the old style horse and can be used when laying brick on the inside of a building. It has a clincher plate on one end and on the other end are legs made of 1%-inch angle steel, standing four feet six inches and five feet high. When closed it does not take up any more room than a 4x4 joist; 100 can be hauled as easily as four old style horses. One man can handle them instead of two men, saving one man’s time and re¬ ducing the cost of your work.

A Saving of 60% in Labor and Material One of the seven buildings at Harvard University, Cambridge, Mass., on which our scaffolding has been used by Hegeman-Harris Company, 360 Madison Avenue, New York. By the adoption of our putlog they have eliminated all putlog holes and 90 per cent of all stays. The splice poles on this building can be spliced in five seconds by one man. The ledger clamps not only prolong the life of the ledger board, but they prevent un¬ necessary accidents. The contractors on this job were so well satisfied with our scaffolding that they are using it on other work now under construction. Evidently they find the 20th Century Economy Scaffolding is the best and most economical on the market. If they can save money, so can any other contractor. Page Twelve The Starting of Your Scaffolding The Completed Scaffolding which was erected by one man. One man will splice ten of these poles while two men are cleating one the old way. Page Thirteen Why Braces and Stays Are Not Necessary Sectional view of the Twentieth Century Economy Scaffolding. Note the absence of stays and how firmly each putlog is anchored to the wall. Page Fourteen Compare the Two Pictures and you can readily see why you Save sixty to seventy per cent by using our scaffolding IS THIS YOUR JOB? There were 2440 splices, 2540 braces and 53,8S0 nails in this scaffolding. The lumber used represents 31 truck loads of 2*4 tons each. Contractors are beginning to realize that by overloading their scaffold¬ ing with braces and stays they are weakening the scaffolding instead of strengthening it. A SCAFFOLDING TO BE PROUD OF There were 1200 Putlogs used on this job. The absence of stays and rack stays gives a clear staging at comparatively low cost. Page Fifteen GEORGE A.

Dear Sirs: Referring to our conversation about the experience we have had using your patent staging, we are pleased to say that we have been users of this staging for a great many years and have had the greatest satisfaction with same, both in the economy of erection, dismantling and safety. Your patent putlog has pleased us very much by its in and out staying of the staging and has eliminated a great deal of staying which we have found in the past to be a considerable item both in regard to material and labor wasted. We feel that by using your putlog that the staging is safe from any swaying in and out and have found that the men working on the stage have a great deal of confidence in their safety. We would not hesitate to recommend it to anyone requiring struction. Very truly yours, staging for building con- F. S. BRENNAN COMPANY, F. S. Brennan Page Sixteen PANZIERI-HOGAN COMPANY, INC.

We are pleased to advice you that we used for outside scaffolding on the above building, the putlogs manufactured and sold by you with very satisfactory results. The periphery of this building is approximately 800 feet and although we used a number of your putlogs, at no time in the course of construction did any of them pull out from the walls. We find they make a perfectly safe staging and are fully sufficient as in and out stays or ties. Very truly yours, CULHANE-DOOLEY, INC., By J. M. Dooley.
