Fastening Motors to Ceilings Without 

 Scaffolding or Tackle 



IT is hard to attach motors to ceilings or 

 overhead beams in factory rooms. Here 

 is a mechanism or de- 

 vice which is said to do 

 this with great ease. 

 It is a portable elevator 

 or tiering machine, and 

 it is employed to elevate 

 and hold the motor in 

 position until it is fas- 

 tened to the ceiling, thus 

 eliminating scaffolding, 

 tackle and hoisting ar- 

 rangements. Four to 

 six motors can be in- 

 stalled in the time for- 

 merly required for the 

 mounting of one. Of 

 course the machine can 

 also be used for inspect- 

 ing the motors, for tak- 

 ing them down to be re- 

 paired, for renewing 

 pulleys, and for putting 

 up shafting. 



The machine itself 

 consists essentially of 

 an elevating platform 

 with two uprights or 

 guides and a revolving 

 base with a ball-bearing 

 center on which it swings 

 like a turntable. The 

 whole unit is mounted 

 on a wheeled truck 

 equipped with a floor 

 lock. It was primarily 

 designed for the piling 

 or tiering of bales, cases, 

 barrels, etc., in storerooms and warehouses, 

 thus enabling the entire space up to the 

 ceiling to be utilized. Two sets of elevating 

 gears are provided. 



The Portable Elevator or Tiering Machine 

 The machine was primarily designed for piling 

 bales, cases, barrels, etc., in warehouses, so 

 that space up to the ceiling could be utilized. 

 Two sets of elevating gears are provided, one 

 operating at high speed and handling loads 

 up to 800 pounds, and the other at a lower 

 rate of speed for handling from 800 to 1,800 

 pounds. It will elevate loads from six to 

 twenty feet. The frame is hinged so that the 

 top section can be folded over to facilitate the 

 passage of the machine through doorways 



Looping the Loop in a Rocking Chair 

 — for Exercise and Diversion 



GLANCE at this rocking chair. Imagine 

 yourself resting in it, strapped in, too, 

 around chest and loins. 

 It seems restful enough. 

 But why the straps? 

 Just for safety, friend. 

 For this chair aspires to 

 demonstrate perpetual 

 motion, once it gets 

 started. As you rock, 

 it gathers momentum 

 until finally — hold your 

 breath — it turns you 

 over and over and over 

 like a cart-wheel. 



The skeleton frame- 

 work of the chair is 

 composed of two ver- 

 tical, parallel elliptical 

 hoops fastened together 

 by a number of hori- 

 zontal tie-bars. To 

 these tie-bar's the seat 

 and back of the chair 

 are attached, and also 

 the straps which hold 

 you while you are cart- 

 wheeling. A bar at 

 about shoulder-height 

 acts as a hand-grasp. 



You seat yourself in 

 the chair, strap your- 

 self in, grasp the hand- 

 bar and give yourself a 

 swing in the usual man- 

 ner. You start off 

 gently enough, but your 

 progress depends upon 

 your own physical exer- 

 tion. Before you become seasick, it is 

 best to reverse the direction of the motion 

 and thus bring the chair to its normal oosi- 

 tion, letting it gradually subside. 



You sit in this chair, strap yourself in, grasp the handle-bar and start rocking, turning cart-wheels, 

 if you like and as long as you like. To bring the chair to a stop you reverse the motion
