To allwkom z'tmqy concern:

Be- '1; known that I, EDWARD L. Mneirm, a citizen of the Unitedi Stat'es, residingat New York, in the eounty of :New York-and Stateoir' New York, haveinvented certain new and; useful Improvements in Feed- Gages for use on Printing-Presses, of: which the following isa specification.

This invention relates-j tofeed gages for use On printing presses, of'the %eneral type shown for instance in my. w 2%1-556 of'May 17th, 1881, in whichthereis a prong for insertion through a hole'or slit in atympan sheet, two armsadaptedto overlie the tympan sheet, a vertical hea-d member eonnecting the prongand the arms, and a tongue projecting" thnough an opening: in the he'ad member and having bent po'rtions gripping the edges of -the two armsgwhereby the tongue may be slid to different positions a-long the arms so that it' will project hold of the tongue on the arms dependson the resiliency offthe parts, andil havekfound that the tongue wi1l'not ioe firm1yheld in position at the outer ends of the arms, particul'arly' after-the device has been'inuse for some time. Accordingly, onelof thieobjects of thepresent invention is to provide a' construction in which 'thetwo armsaforesaidfare arrangedso that they diverge from the headmember with whichithey are integral, the distancebetweentheiarlns adj'acent; the point where theyijoin thehead member being such that when the gripping portionsof the tongue are over theedges of the arms adjacent this point, the grip ping portions will be firmly held: other words, the distanoe'between therarms'atthis 40 point is slightly larger than the distanoe hetween the gripping portionsof the tongue I so that the tongue willbefrictionallyheld.

And the tongue is adjusted to difi'er'ent positions toward the outer end ofthe two arms'the friction is increased because the.

' arms-\diver'ge away from tl e head member. The resnltof this is that the gripi'of the at t e outer ends of'the arms as at' thei inatent: No.

A further object ofmy invention is to provide a device'of the kind above referred to. which maybe readily V stamped out of a single piece of -suitable material, in which the connection between the prong and head inernhert'are decidedly strengthened and stifi'ened, and in'which provision is' made for; an; opening in the head member through which the adjustable tongue. may project which; opening? extends tothe lower edge ozfithe head member, thoughthe surrounding edges? defining.- the op ening; are everywhere mbroken.

This head-piece has usual extension symmetrically on opposite sides of the connection with the prong and has backwardly turned wings 1e and downwa d pr jections or points 15 which n'iay e forced into the tympan sheet to hold the device in aosition. Extending baclivardly from the head member 12 is a pair of integral arms, which for reasons hereinafter explained, diverge away flOl each other, beginning with their point of connection to the head mem her. At their outer ends these arms are as usual provided on their outer edges with cut-out portions 17.

The usual form of adjustable tongue is shown in Figs. 2 and 3 and comprises a tongue proper 18 extendingfrom a cross plate 19 having an upstanding finger part 20 and dependent gripping fingers 21. In use the tongue extends through an opening in the head member, as shown in Fig. 1 for instance, and the tongue is engaged with the arms by slipping the gripping fingers 21 over the arms at the cutouts 17, after which the arms 16 are pressed toward each other so that the gripping fingers may engage the edges of the arms inwardly of the cut-outs 17. Obviously, in order to hold the tongue on the arms the distance between the grip ping portions of the tongue should be less than the distance between the outer edges of the arms at any point of their length excepting only the cut-out portions 17 so that the tongue will be held frictionally at any adjusted position along the arms. If the arms were merely parallel, instead of di vergent, repeated pressing together of the ends of the arms would tend to destroy their resiliency so that after a time the tongue would not be held firmly if adjusted to a position toward the outer ends of the arms. With the present construction there is always the proper tension to hold the tongue in any adjusted position. Obviously, the inherent resiliency of the gripping fingers 21 is of some assistance.

The opening 22 through the head member 12 is formed in the blank illustrated in Fig. l. as shown, with its lower edge, which is the one nearest the prong 10, formed on a curve indicated at 24:, and the root of the tongue is bifurcated to constitute the edges defining this curved lower part of the opening 22. When the device is formed up from the blank shown in Fig. 4 the prong 10 is bent under the head-piece 12 as shown in .=;1gs.

5 and 6, so that the bifurcations of the prong are at rlght angles to the head-piece, as is also the curved edge 24. The result of this manipulation is that there is an opening in the head-piece defined by unbroken surnnding er yes of the material, which openndc rem top to bottom of the head a tongue 18 projecting through this opening may, if desired, lie fiat on the tyinpan .heet. In addition, it will be seen that the bifu cations of the prong join the head-piece by way of an upward and outward curve, which strengthens the connection between the prong and the head-piece and minimizes the possibility of breakage at this very important point. Obviously, the action upon the metal connecting the prong and the head-piece in inserting the prong through the tv ipan sheet is to bend the metal along a horizontal line of junctions, and if the bend originally formed at this point were simply in a horizontal line crystallization would take place after a while, with resultant fracture. With my construction however. the original bend of the metal is not in a horizontal line merely but is a twisted bend so to speak which resists crystallization.

It will be understood that the device formed from the blankshown in Fig. 4 is of thin sheet metal of uniform gage throughout, and tl at the punching out and forming up is done by means of dies in any usual or preferred manner. I find that the form of blank shown in Fig. lis very easy to manufacture because the outer edge is struck with a single stroke, simplifying the operation and lessening the cost of manufacture.

I claim:

1. In a device of'the kind described, a 1.00 prong member, an apertured head member integral therewith, divergent arms extending from the head member substantially as and for the purpose described, and a tongue having portions including theouter edges of 1 5 said arms and extending through the aperture in the head-piece.

2. In a device of the kind. described, a prong member, an apertured head member integral therewith, divergent arms extending from the head member substantially as and for the purpose described, the prong nember having bifurcations which connect to the head member and define the lower edge of the aperture therein, said bifurcations being disposed atright angles to the head member, and tongue having portions including the outer edges of said arms and extend inc; through the aperture in the headpiece.

In a device of the kind described, a prong m mber, an apertured head member integral therewith, arms extending from the head member substantially as and for the purpose described, the prong member having bifurcations which connect to the head member and define the lower edge of the aperture therein, said bifurcations being disposed at right angles to the head member, and a tongue having portions including the outer edges of said arms and extending through the aperture in the head piece.

l. In a device of the kind described, a prong member and a head member integral therewith, the prong member having bifurcations disposed at right angles to the head member and gradually curved thereinto.

5. In a gage of the class described C0111- prising a head piece and a penetrating prong 10 integral therewith the line of junction between the head piece and the prong being on a gradual curve. a

6. In a gage of the class described cornprising a head piece and an integral penetrating prong the latter having curved bifurcations which connect the prong to the head piece.

In testimony whereof I affixniy signature;
