Referring more particularly to the drawings wherein like numerals of reference indicate corresponding parts throughout the several views, there is showniniFigure llone formof myinvention. In this form of the invention there is provided a substantially U-shaped body whichi'shere indicated as a. whole by the numeral 1,7tl1e lowerportions of the legs 2 of this body being flattened. as indicated at 3. and provided with the transversely aligned fulcrum bolt receiving apertures 41-. The free ends ofthes'eportions'3 are p eachiormed toprovide a hook 5, the shank portion of which is flattened to extend in a plane at right angles to'theplane ofthe flat surfaces of theportions 3. Each of these hooks is of a size to snugly receive a flange of a channel beam of a certain thickness and detachably secured to each of the hooks 5, by a suitable bolt 7'is a removable hook 8: which may be formed to take athicker or athinner beam-flange than the oppositehook or* the hook towhich it is attached. From this it will, of course, be under-stood-that thedevice. may be permanently provided with hooks of a given size and a number of: different sized hooks may be provided to take'the place of the hooks 8. l p

A fulcrum bolt 9 is providedto extend across between the legs'or flattened portions of the U-shaped member, one end of which bolt is provided with a headlO and adj acent the head with an encircling recess while the opposite end thereofis bifurcatedasindicated at 12 and has pivotally mounted between-the furcations a pin 13. Wheninserting the bolt "9 theipin :13 is turned to extend longitudinally of the bolt so that the pin end may be ex tended through the selected aligned apertures 4.

When the recessed portion at the head end of the bolt is engaged in one aperture, the other end of the bolt being extended through the opposite aligned aperture, then the pin 13 is turned to extend transversely of the bolt in the manner shown to prevent accidental displacement of the bolt.

The present device is designed primarily for use about and in the construction of railway cars although, of course, it is not restricted to such use for it may be used in any place where rivets are to be secured in iron beams of either angle, T or channel shape. When used, for example, upon a channel beam two of the hooks at the end of the U- shaped member are engaged over the edge of one flange of the beam as shown in Figure 1 and there is then extended through the member 1 at a point forwardly of the bolt 9, the handle 14 of a bucker which is indicated as a whole by the numeral 15. This bucker is in the form of a double headed hammer, the two oppositely directed heads being each indicated by the numeral .16. Each of these then be worked upon by a suitable rivet hammer to form a head thereon.

In Figures 5 and 8 I have shown modifications of the structure shown in Figure 1, these modified structures being adapted for use upon various forms of beams.

In the form shown in Figure 5 there is pro vided a U-shaped member which is indicated 7 as a whole by the numeral 18. Each of the legs 19 of this beam engaging member has its free end formed to provide a hook 20, one of the hooks being slightly different in size and shape from the other. The yoke portion 21 of this member is apertured to receive a rivet 22 which passes through an end bar 23 of an elongated rectangular frame 24 thus holdlng this end of the frame in swivel connection with the beam engaging member 18. The frame 24 which may be termed the ad- ]uster has the side bars 25 thereof provided with a plurality of apertures 26, the apertures 1n one side bar being directly in alignment with apertures in the other side bar. These apertures are provided to a-djustably receive a fulcrum pin 27, this pin being of the same character as the pin shown in Figure 2 and indicated by the numeral 9. i

In Figure 5 there is shown the application of this modified form of my invention, the same being shown applied to a channel beam in which the flange thereof is turned away from the worker. This channel beam is indicated by the numeral 28. With one of the hooks 20 of the device engaged over the flange of the beam the handle of a bucker 29 is extended through the adjuster 24 and across the pin 27 Pressure is then applied to the bucker handle to force the head of the bucker against the head of the rivet which is to be hammered down after which, of course, the hammering down or swaging of the other end of the rivet may be accomplished.

The second modification of my invention is shown in Figure 8 and in this form there is provided a U-shaped member which is indicated as a whole by the numeral 30 in which each of the legs 31 has its free end turned outwardly as indicated at 32, the upper face of each of which out-turned portions or feet is serrated or corrugated as indicated at 33. This form of my device is for use upon channel beams where the flanges are directed toward the operator so that one or the other of the feet 32 must engage over the flat back surface of the channel beam as shown in Figure 8, the beam being here indicated by the numeral 34. Each of the legs 31 of the member 30 has attached thereto by means of a bolt 35 a clamp 36. Each of these clamps comprises a straight portion 37 in which is formed a bolt receiving aperture 38. The leg 31 of the U-shaped member adjacent each clamp is provided with a series of similar bolt apertures 39 which are connected by slots 39a. The portion 37 of each clamp has extending from one end thereof a leg 40 which is offset therefrom and as shown one of these legs extends substantially parallel with the portion to which it is attached while the other one extends outwardly at an angle thereto. As will be readily understood from this one of these clamps is designed to engage over the flange of a channel beam where the inner face of the flange is at right angles to the body of the beam while the other of the clamps is designed to' engage over a flange of a beam where the inner surface forms an obtuse angle with the inner face of the beam body.

The yoke portion of the beam engaging member 30 is pivotally attached by means of a bolt or rivet 41 to an adjuster frame 42 which is of the same construction as the frame 24 and has extending transversely between the side bars thereof a fulcrum pin 43 o; the same construction as the pins 9 and 2 I When the beam engaging member 30 is in operative position as shown in Figure 8 a bucker 44 of the same type as that previously described and referred to by the numerals 15 and 29 is then placed in position with its handle extending transversely of the pin 43 and with one face of its head overlying the head of a rivet in the beam 34.

From the foregoing description it will be readily seen that with a rivet bucker of the character described one man may perform a riveting operation with greater ease than has heretofore been the case when it has been necessary to hold a bucking tool or bar in place against a rivet by positioning it against any body placed conveniently in the vicinity of the riveting operation. With the present device the bucking tool can be firmly and easily held in position and further than this where the frames or adjusters 24 and 42 are employed the bucking tool may be swung to any one of several positions without disconnecting or detaching the beam engaging member to which the adjuster is,

pivotally connected. By providing the legs 31 of the U-shaped member 30 with the apertures 39 connected by the slots 39a adjustment of the clamps 36 on the legs may be made by turning the clamp crossways to the leg which operation will also turn the bolt 35 which is tightly fitted in the aperture in the clamp. This will bring the flattened portion of the bolt into such a position that it may be slipped along the slot 39a until the bolt is brought to the proper aperture 39 whereupon the swinging of the clamp back to a position parallel with the leg will turn the bolt in the aperture so that it will be held in the proper place.

The ends of the adjuster frames 2 and 42 of each of the modified forms of my invention is provided at its end opposite the end to which the beam engaging member is attached with a suitable aperture to permit the passing therethrough of a bolt when the nature of the construction upon which the device is used is such that these adjusters may be secured to a fixed portion thereof. IVith the adjusters thus mounted the user of the device is relieved of the necessity of supporting the device while applying pressure to the bucker.

Having thus described my invention, what I claim is 1. A device of the character described, com prising an elongated rectangular frame having the side members thereof provided with aligned apertures, a substantially U-shaped member having spaced side legs and a straight yoke portion connecting said legs at one end thereof and positioned against one end of the frame, a pivot pin connecting the said yoke portion of said member with the adjacent end of the frame whereby relative rotary motion about an axis longitudinal to the frame, may be effected, between the frame and the member, means forming a part of said member for engaging a body in which a rivet is to be set, a pin member disposed transversely of the frame in a pair of aligned apertures, and a rivet bucking element comprising a yoke portion in abutting relation to one end of the frame, swivel connecting means between the yoke portion of the member and the frame, said member having the sides thereof provided with longitudinally spaced apertures having connecting slots therebetween, a lateral extension formed integral with the free end of each side portion of the member for engagement with a beam, a clamp plate adjacent each of the side portions of the member and having one end offsetwith respect thereto for engagment over. an adj acent flange beam, a bolt member extending through each clamp plate and through an aperture in the adjacent portion of the member, said bolt being flattened intermediate its ends to facilitate; its movement from one aperture to another through a communicating slot, a pin member extending transversely of said frame through aligned apertures, and a rivet bucker comprising a handle extending through the frame and abutting said pin and a head carried by the handle and adapted to engage the head of a bolt.

3. In a device of the character described, an elongated rigid frame having spaced parallel side members and a straight cross connecting end member, said side members having transversely aligned apertures, a body engaging member of substantially U-shaped design having parallel side members and a straight connecting yoke member, said yoke member and the end member of said frame being in abutting relation, a pivot connectingthe abutting end and yoke members, a laterally directed hook formed integral with the free end of one side member of said U-shaped member, a pin disposed transversely of said frame in aligned apertures in the side members thereof, and a rivet engaging tool having a head and a handle extending through the pin.

In testimony whereof I hereunto afiix my signature.

HENRY B. MORGAN.
