The saw is geared directly to the motor and works in either direction. It will cut thirty 

 thousand cakes of ice per day, thus equaling the work of sixteen men with eight horse-teams 



This Ice-Cutting Machine Takes the Place 

 of Eight Horse-Teams 



EOriPPEU with a thirty-five horse- 

 power gasoline motor, which both 

 dri\es the machine and operates the cuttinij 

 saw, a new type of ice-sawing machine has 

 been put on tlie market by a western 

 manufacturer. It will cut one cake of ice 

 a second, or thirty thousand cakes a day, 

 thus c()ualing the output of sixteen men 

 and eight horse-tciims. 



The machine is one of the few gasoline 

 ice— awing machines in the field at the 

 present time, whicli can be rim in either 

 direction with cciual success. Spikt-d 

 wheels driven by gears and diains from the 

 motor m()\e the machine over the ice, and 

 the single large ice-saw may be raised or 

 lowered to cut to a depth of from six to 

 sixteen inches according to the thickness of 

 the ice. The speed of the apparatus is 

 regulated by means of a friction disk similar 

 to that used on some aulnmobiles. The 

 saw is geari'd directly to the motor and 

 cuts in either direction. Since the machine 



can cut in either direction, it is not neces- 

 sary to turn it around at the end of a cut, 

 but merelv to shift it back. 



Taking Care of Automobile Tires 

 at the Front 



IN THK earl\- ilays of the war the wastage 

 of automobile tires in France was alarm- 

 ing. The suddenness and the extent of the 

 effort necessary to stem the tide of invasion 

 put economy out of the question. Tires 

 were abandoned as soon as the\' were 

 damaged and claims for new ones were 

 ne\er (juestioned. The drivers hail neither 

 time nor tools for making repairs, in most 

 cases. But now each dri\er works from a 

 base or dejiot, to which the worn or 

 damaged tubes and casings nuist be 

 returned. From the depot the damaged 

 tires are sent to central repair stations 

 wiiere they are rei)aired, tested, dried, 

 t.iKed .mil ]iacked in cardboard boxes 

 marked with all necessary descripli\e data. 

 These repaired goods are stored in special 

 storehouses and distributed as needed.
