FEEDER FOR PRINTING-PRESSES.

Be it known that we, ELTON BREWER and (liner- A. CHESHIRE, cit zens of the United States, residing at Des Monies, 1n

the county of Polk and State of, Iowa. have invented a certain new and useful Feeder for Printing-Presses, of which the following is a specification.

The object of our invention is to provide a feeder for printing presses of simple, durable and inexpensive construction, especially adapted for use in feeding books or pamphlets and so arranged that it may be readily and easily adjusted to fit. books or pamphlets of different sizes, and also so arranged that the feeder fingers may be inade to firmly engage the lower one only of the pamphlets or books, and said lower'one' may mg supporting bar 13 capable of movement then be readily and easily moved from under the pile of books contained in tlie'feeding hopper. Our invention consists in certain details,

'in the construction, arrangement and combination of the various parts of the device whereby the objects contemplated are attained. as hereinafter more fully set forth, pointed out in our claims and illustrated in the :u-companying drawings,in which- Figure 1 shows a front. end elevation of a device embodying our invention. F ig. 2 Shows a view of same with the central base plate of the hopper removed. Fig. 3shows a sideelevation of one of the curved base plates and its support. Fig. el: shows a central, longitudinal, sectional view through a device embodying our invention, and also illustrating the feed and printing rollers of a printing press to show the arrangement of the feeding device relative thereto. 5 shows an enlarged, detail, longitudinal, sectional view of one of the base plates enibodying our invention, and Fig. 6 shows a view of a part of a device. similar to- Fig. 4 with the base. plate and the lower book or pamphlet therein in an extended position.

Referring to the accompanying drawings, we have used the reference numeral 10 to indicate that portion of the printing press shown. 11 indicates the printing or type cylinders, and 12. the' feed rollers. .All of these parts are of the ordinary construction.

Mounted upon the frame is a reciprocattoward and from the feed rollers. Extcnded transversely of this bar is a cross head 14.,

Adjustably mounted on the cross head 14 Fig.

aretwo blocks 15 secured to the .cross head by :the set screws 16. On each of these blocks is a segmental base plate to form the bottom of the hopper for containing the books or pamphlets. 7 Each of these base plates is made vertically adjustable relative to the block 15 by means of the screw threaded rod 17 which is extended through the block 15 and provided with nuts 18 above and below said block so that each base plate may be independently adjusted vertically and firmly supported in any position of its adjustment. Said base plates may also be adjusted toward and from. eachothcr by sliding the blocks 15 on the cross head 14.

At the end of each of the curved base plates is a series of feeding fingers, each of which comprises astraight body portion 19 capable of vertical movementunder the base plate and having a feeder point 20 at its .upper end. The lower end of each of the body portionslt) is beveled or inclined at 21 and a contractible spring 22 is connected ,to each of said body portions 19 andtends to hold it downwardly. For the purpose of adjusting the finger relative to the base plate, we have provided a set screw 23 mouhted in theJbase plate andprojected to position in engagement with the inclined or beveled portion 21 as clearly shown in Fig. 5. Obviously by moving these set screws inwardly toward the central portion of the base plate. the feeder points 90 are raised, and by withdrawing said set screws the feeder points are lowered.

In order to provide for receiving books or pamphlets of considerable width, we have provided a. central, flat top base plate 24. which is mounted on the cross head 14 in tit e same way as the other base plates before described, and which therefore moves longitudinally in unison with the other base plates. The top portion of this central base plate 24 is preferably made flat as clearly shown in Fig. 1. \Ve have also provided a. hopper-of ordinary construction for bolding the pamphlets contained on the base plates against longitudinal, movement with the base plates. This device comprises a series of horizontally arranged rods 25 with vertical rods 26 adpistably connected therewitlnxsaid vertical rods being designedto vided with slots 27 to receive the end ones of Sald; vertical rods 26 as clearly shown Figs. and 1.

In practical use, the books or pamphlets 28 to be printed are placed-upon the base plates and they'obviousl will be curved in.

the manner illustrated in Fig. 1 substan- Y tially of the same curvature as the base plates, except, that as shown in said figure,

gthe edges only of said books or pamphlets will engageeach other-and the central portions thereof will stand spaced apart from each other. The rods that form the hopper r are adjusted to fit the side and end edges of the books or pamphlets, and the rods at the rear of the hopper adjacent to the feed'rollers are so arranged that they will not stand in line with the lower book or pamphlet so.

that saidlower one isfree to move rearwardly in position inengagement with the feed rollers. \Vhen the base plates are moved forwardly toward the feed rollers, the fingers 20 will engage the lower book or pamphlet and will carry it together with.

the'base' plates toward the feed rollers. As said books, or pamphlets enter the feed rollers they will be flattened out so that they .will enter between the printing rollers in flat condition for printing. a Anumber of advantages are gainedby havingthe base of the hopper made of seg-' mental shape instead'of fiat-one advantage being that the feeder points will more readily 'enter between the books or pamphlets on account of the-fact that their central portions stand .spaced apart, and an-- other advantage is that the books or pamphlets will slide relative to each other more readily'because' the edges only thereof are in engagement with each other.

\Ve. claim as our invention- 1. In a device of the class descr1bed, the

combination of a reciprocating base plate having its top surface arranged with its sides higher than its central portion so that articles to be printed resting, thereon will "'lie in curved positions with'their sideedges ,elcvated and so that the lower one of said articles will have its longitudinal central portion spaced-apart fromthe article above it, a stationary hopper devicefand a finger carried by the base plate and designed to enter between the two lower articles at the point where said articles are spaced apart at their-longitudinal centers.

combination of a reciprocating base plate of its path of travel, to, thereby support articles to be printed in such a manner that the longitudinal centers of the lower articles members desi ned to hold books or'pamhlets on the base plates and to permit the ower one thereof to project beyond the base eating base plate to enter between the two lower articles on the base late.

3.- In a device of the e ass described, the combination of two reci rocating base members curved transverse y of their path of travel, means for adjusting them toward and member detachably sup orted I stationary hopper mem ers designed to hold articles on the reciprocating base members,

I thereon.

combination of a reciprocating support- ELTON e. BRE ER," oAn-EY A. CHESHIRE.
