Having thus described. my invention, what I claim, and desire to secure by Letters Patent, is

1. In a printing or registering beam for weighing-scales, means for causing the impression of the type-numerals to be printed on the ticket, comprising a suitable holder, a pressure-bar having a vertically-sliding pivot connection with the holder, a cam-lever for raising said pressure-bar vertically and intermediate antifriction devices interposed between the cam-lever and the pressure-bar, carried by said pressure-bar; substantially as described.

2. In a printing or registering beam for weighing-scales, means for causing the impression of the type-numerals to be printed on the ticket,comprising a suitable holder, a pressurebar having a vertically-sliding pivot connection with the holder, antifriction-rollers carried by said pivot and a cam-lever in operative engagement with the antifriction-rollers; substantially as described.

3. In a device of the character described, a

pivoted vertically-movable prcssure-bar, antiiriction-rollers carried thereby, cam-lever For engaging said antifriction-rollcrs to move the pressure-bar vertically and devices carried by the cam-lever and engaging the rollers for holding them in engagement with the operating, means; substantially as described.

i. In a device of the character described, a suitable holder having vertical slots therein, a pressure-bar having a shaft or pin guided in said slots, antifriction-rollers on said shaft or pin, a lever having cams engaging said rollers; substantially as described.

5. In a device of the character described, a suitable holder provided with vertical slots therein, a pressure-bar having a shaft or pin engaging said slots, antitriction-rollers on said pin, a lever having cams engaging said rollers and caps secured to the lever and engaging the antii'riction-rollers; substantially as described.

In testimony whereof I ai'lix my signature in presence of two witnesses.
