The lower brake-block f is reversibly secured to the front side of the brake-body,

. preferably by a screw passing threugh a longitudinal slot k of the block. Willen the active upper corner of this block becomes worn, the opposite sharp corner is brought into position to replace the worn one by simply releasing the block and reversing it. When both corners of this lower block become worn, they may be resharpened by removing the' block, filing its front end, and replacing the block. The slot of the block permits the same to be adjusted toward the upper block to compensate for the removed stock. In order to revent swiveling or turning of the slotted b ock when its lower end is out of contact with the shoulder l near the lower end of the brake-body, said block is provided on its front and rear sides with stop-lugs m m, located on opposite sides of its slot. One or the other of these lugs projects into a longitudinal slot m in the brake-body, according to the position of the block, as shown in Figs. 3 and 4. These stop-lugs while preventing lateral displacement of the block permit its adjustrnent relative to the upper block.

While greatly prolonging the life of the brake, theimprovement has the further advantage that when the brake is once attached to the machine itlneed not be removed, as the adjustment and change of position of the blocks can be readily effected without disturbing the brake-body.

N is the customary spring for yieldingly holding the brake in engagement with the assembler-slide. Onel end of this spring is secured to the upper end of the brake, while its opposite end is attached to an ear n, projecting forwardly from a bracket or plate o. This bracket is adjustably secured to the frame A by a set-screw o', passing through a horizontal slot o2 in the bracket, or by other suitable means, so that upon loosening the screw the bracket can be adjusted to regulate the tension of the spring N, as required. The bracket is preferab y provided with an upwardly-extending lug or finger-piece 03 for conveniently shiftin it when loosened.

As shown in the rawings, the brake may ybe provided at' its upper end with a forwardly-- projecting finger-piece p, by which it can be conveniently released by hand. 'Ifl desired, other means may be employed for preventing the slotted block V,from swiveling on its fastening-screw. For example, the raised lower portion of the brake-body may be provided at both sides with stop-lugs i', which overlap the opposite side of sai 1.
