In the bearinghousings on these brackets coiled springs were placedover the bearings to resist the upward thrust from thecutter spindle which replaced the rotary broom. The cutter spindle consists of two built-up wooddrums, 18 in. in diameter, mounted on the ordinarybroom shaft. On the drum surface are numerouscutters or teeth of the form and dimensions given inthe scale drawing reproduced herewith. The cut- studded with sixteen teeth each. The inside collars are2-in. x 3-in. steel, with six teeth each. The totalnumber of teeth is, therefore, seventy-two. The halvesof each split collar are drawn together with two on each side. The shanks of the cutters are inserted in the collarsand are held loosely in place by means of the tapered. DIMENSION SKETCH OF STEEL TOOTH FOR ICE CUTTER plugs. These in turn are locked in position with cotterpins. The wood drums are recessed to accommodatethese, thus providing a keying effect of the collarsagainst rotation, supplementing friction. Provision is made for raising and lowering the outerspindle by means of chains attached to the bearingsand winding upon a shaft driven from a geared hand-wheel staff. The driving motor is a GE-52 motor onthe floor of the cab, geared to a jackshaft mounted inthe axle bearings. By means of a chain the jackshaftin turn drives a countershaft under the body, fromwhich chain drives lead to the cutter spindle and to arotary broom at the rear end. With the cutter on one end, the broom on the other,and the two wing plows on the side, this outfit is most
