As Good as Ten 

 Strong Men 



CONVEYING sys- 

 tems which are 

 very costly to instal, 

 become good invest- 

 ments when there is a 

 shortage of labor. An 

 example of this is the 

 long overhead mono- 

 rail erected in a Tole- 

 do, Ohio, plant. The 

 electrically operated 

 crane is handled by 

 but one man. It car- 

 ries boxed automobiles 

 from the plant to the 

 flat cars on the siding, 

 where the turning on 

 of the electric motor 

 lowers them into place. 

 Formerly it took ten 

 hands, with trucks and 

 gangways, to accom- 

 plish the same lal)or. 

 The work does not re- 

 quire a highly trained 

 man. Awomancandoit.

INVENTIONS previously used 

 exclusively for war purposes, 

 are now finding their way into 

 industry. Even the submarine, 

 associated with destruction, has 

 something to contribute. For 

 instance, why not periscopes for 

 railway engineers? Why is it 

 necessary for the engineer to lean 

 out of his cab to see the track 

 ahead of him, or the signal of the 

 conductor or flagman in the rear 

 of the train? 



According to A. G. Spencer, 

 of London, England, periscopes 

 would be a great help to all loco- 

 motive engineers, eliminating 

 much danger and inconvenience. 

 He has invented two peri- 

 scopes which can be attached to 

 an ordinary locomotive cab, to 

 enable the engineer to obtain an 

 unobstructed view of the track 

 ahead and of his train in the rear. 

 The periscopes are supported 

 by rubber or other flexible means 

 in brackets, so that they can 

 be readily adjusted i]i position or 

 turned about a vertical or hori- 

 zontal axis. The space between 

 the periscope and the roof of the 

 cab is filled with rubber rings. 

 One of the periscopes is tele- 

 scopic and is in two 

 parts held together 

 by a wing-nut and a 

 bolt. It is provided 

 with windows, a re- 

 movable cover and 

 projections which bear 

 against the securing- 

 clamps. The peri- 

 scope may be of lazy- 

 tongs type or otherwise 

 adjustable in length, 

 and the mirrors may 

 be protected from 

 smoke by a hood or 

 casing. 



So equipped, in an 

 emergency, the engi- 

 neer is able to see all 

 that is necessary, with- 

 out leaving his post at 

 the throttle.
