`ATL.CEMENT FOR PRINTING-PRESSES.

"i the feed table of such a press so :1s-to ta eithe.same entirely out 'of the way of a 'card\on thecylindcr after the same has been is-Pltd printing presses of the above `indicalfted type the blank'cards, which may be o-any size an hand downen `inclined feed table the sur A#face of whichvi's normally in a plane substantially tiiit'to the periphery-dir it-he feeding'cylnk er, is providedrvith ,grippers or seizing thedmiienedge of e'V 25.9Qrdand'feeding it around over the printing -f` ff`bed which reciprocates in timed relation beneaththe feeding cylinder.- After printing of /the carcLthe same is carried bythe feed- .'ling cy1i`i'ider 'be neath the feeding table and discharged lto?"suitable conveying means. Since the cards are rclativeiytff and unyie'ldin theyare carried by the cylinder at an ang e vto theperipli'cry thereof and will vwipe across theend surface ofthe feed table as they are carried beneath the same. It vis E the printed side which is thus wiped and, as

the ink is of course wet, it frequently happens that switchingr land faulty work resuits. It is the primary object of iny in- '40 `vention to lift the feed, table at the moment that the card is carried beneath the same,

and to lower said feed table to working position immediately thereafter. y

A further object of my invention is to 4p provide a device of th'e above character which may readily be attached to printing presses of common use and construct-ion with the addition of practically no operating parts., 60 .Av further object of my invention is to make the lift-of the feed table adjustable te the minutest degree so' as to readily adapt the movement of the feed table to the size o? the cards being printed. A fui-ther oh`ect of my invention is to provide ineens forlifting and returning the Specification of Letters Patent. Application filed-September 23, 1911. Serial No. 650,966. A

.The frame of the printing press comprises longitudinal frame members 10 andf11, rear .uprightsf 12, a transverse frame member 13, intermediate uprights 1 5 supporting oblique frame pieces 16 upon which rests the feeding table 17, and central upright brackets 1S providing journals for the feedingcylinder 19 below which reciprocates the printing bed not shown. The rear portion gf the feedv table 17 is normally stationary; Said printing table is cut across by a beveled joint 20 as shown in Fig. 1, the forward poi-- tion of the table 2l being pivoted to a rod 22 journaled in the upiiglits 12 and :i'haliger 23 depending from the lower side of stationary feed table 17, this construction per initting the forward part 21 of the feed table to be swung back so that access may be had to the printing bed when same is in its rearward position. The front edge of feed table 2l is provided with a lip 24 and with spring fingers 25 which as shown in dotted lines in Fig. 1 come into close proximity to the periphery of cylinder 19 when movable table 21 is in its lower or operative position, said movable table then having itsA surface in the same plane with that ofstationary table 17, said plane being ap roximately tangent to the periphery of der.
