JOHN G. BOEHRINGER AND JOSEPH A. BOEHRIN GER, OF BUFFALO, NEW YORK.
PRINTERS PRESS-GUIDE.
SPECIFICATION forming part of Letters Patent No. 447,293, dated March 3, 1891.
Application filed November 27, 1889. Serial No. 331,743. (No model.)
To all whom it may concern:
Be itknown that we, JOHN G. BOEHRINGER and JOSEPH A. BOEHRINGER, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Printers Press-Guides; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
The object of. this invention is to take the place of common pins, generally used, or the more expensive devices as guides to the paper, in connection with the tympan orblanket of printing-presses, and the invention as constructed and applied will be understood by the following specification and claim.
In the drawings, Figure 1 is a perspective, full size, with the spring swung off; Fig. 2, a perspective with the adjusting-screw part raised; Fig. 3, a perspective of the whole in position; Fig. 4:, a side elevation.
a represents the main body of the device, made of brass, and a the front part hinged thereto. Through the side of the front part ct runs a fine-threaded screw 0, having an octagonal-shaped head, but fiat at the end.
Attached to the under side of the body a, is a plate at of steel, being the same width and length as the parts a ct and provided with two pins or points 61' d, projecting directly under the adjusting-screw c and in line therewith, the head of the screw setting 17 is a flat spring pivoted to the top of the part a, and swings onto the top of the hinged part a, keeping that down when the guides are set and the press working. There will be three in a set. The bottom 01 will be pasted on the bed or blanket, the pins d d penetrating one sheet thereof, thus keeping the guides in place. thrown back and the hinged part a raised, as in Fig. 2. Then the screws 0 in use are turned to the required gage, the edge of the paper coining against the flat heads of the screws. These screws can be adjusted to the one-hundredth part of an inch, allowing rapid feeding and without damaging the tympansheets.
We do not claim in a feedgage the combination of the base provided with means for securing it to the paper or platen and the adjustable gage mounted on said base andprovided with a head.
Ve claim- In a feed-guide for printing-presses, the adj Listing-screw 0, adapted to work in a hinged top, in combination with a pin or pins d 61', forming part of the device, substantially as specified.
In testimony whereof we affix our signatures in presence of two witnesses.
