New Long-Handled Trowel Saves 

 Cement Finisher's Time 



THERE is no need to break your back 

 or to use pads or boards to protect 

 your knees when you are finishing a cement 

 sidewalk. Use the long-handled trowel 

 shown at the bottom of this page. 

 This tool differs from that generally used 

 for finishing 

 work, in that it 

 has a long, 

 broom-like han- 

 dle which is- at- 

 tached to the 

 face of the 

 trowel itself. 

 The lower end 

 of the handle is 

 pivoted in the 

 center of a short 

 bar with toggle 

 members at each 

 end attached to 

 a second bar 

 pivoted by nut 

 and bolt to a 

 U-shaped piece 

 of metal laid on 

 its side and rig- 

 idly attached to the face of the trowel. 



The double motion secured through the 

 use of the tw'O pivoted bars and the con- 

 necting toggle arms causes the near edge 

 of the trowel to raise when pulled toward 

 the workman and the far edge to raise 

 when pushed away from him. Thus is 

 overcome the difficulty occasioned by the 

 tool's digging into the surface. 



In ordinary- work it is said that one man 

 with such a long-handled trowel can finish 

 as much surface as five or six men with the 

 usual tool and knee pads.

spite of the fact that Science and 

 Invention are constantly devising new 

 means of alleviating suffering and especial- 

 ly of affording comparative comfort to 

 wounded soldiers, there are times when 

 the old, old methods are resorted to as the 



best available. 

 In the accom- 

 panying photo-

 mule is shown

 workers could 

 employ for

 of battle in the 

 mountains overlooking the plainofMonastir. 

 The stretchers were attached, one on 

 each side of the mule, with the heavy yoke- 

 saddle between. The mule, gingerly pick- 

 ing his way, could go where the automobile 

 could not — right out into the midst of the 

 prostrate forms and through the narrow 

 mountain passes in the bend of the Cerna 

 river, where the Serbs made their great 

 play, and on to the railroad from Salonika.
