��A Giant Grinder Which Goes to Its Work

IF you have an axe to grind, it is no longer necessary to bring the axe to the grinding wheel, for a portable grinding wheel of full-sized proportions has been brought into the grinding field.

���The newest thing in portable tools is a grinder which goes to the blade to be sharpened

��Numerous small grinding equipments in- tended for light work have been intro- duced from time to time, but only re- cently has a man-sized portable grinder been a reality. A huge motor mounted on a three-wheeled truck supplies the driving energy to the abrasive wheel through flexible tubing. In opera- tion when the speed has been adjusted to suit the needs of the workman, he grasps the handles of the wheel on either side and brings it against the object to be ground at any angle or any pressure desired. Grinders of this type are intended for use in foun- dries or in factories where there is a great deal of heavy abrasive work to be done.

For the mechanic who values convenience and neatness of work, this new ajjpliance is well-nigh per- fect.

��A Test for Baggage-Smashers

EXPRESSMEN who are accustomed to slamming trunks around like pasteboard boxes may not have to be cautioned to handle with care the baby elephant of a trunk pictured, for they will do well if they budge one corner of it. It was built in Fargo, N. D., and is eighteen feet long, ten and a half feet high, and ten feet wide.

To build this monster near- ly two thousand feet of lum- ber were used as well as five hundred bolts, eighty-seven yards of canvas, ninety yards of lining, fifty-four pounds of nails, half a ton of iron, and ten gallons of paint and pastes.

The trunk is made in sec- tions, and can be knocked down and stored under cover when not on exhibition. It is canvas-covered. The slats are made of planks ; the cor- ners and binding are of heavy iron and are bolted on. The lock is made of bronzed wood, so that it looks like brass. The handles are of wood and are covered with imi- tation leather. The trunk is wired for electric lights.

On the inside are a ten-foot showcase and two dray loads of trunks, bags, etc.
