To aZZ whom it may concern.-

Be it known that I, WALTER T. GORDON, a c tizen of the United States, residing at Juniper, 1n the county of Umatilla and State of Oregon, have invented new and usefullmprovements in RivetingDevices, of which the ollowing 1s a specification.

My invention pertains to riveting devices; and 1t contemplates the provision of a simple and inexpensive device constructed with a forming part of this specification, in which- Figure 1 is a view, partly in side elevation and partly in vertical longitudinal section, of

a device constituting one embodiment of my invention. Fig. 2 is a transverse section taken in the plane indicated by the line 2 2 of Fig. 1 with some parts in elevation. 3 is a detail horizontal section taken in the plane indicated by the line 3 3 of Fig. 1 look-' ing downwardly. Fig. 4 is a detail sectional view illustrating the relative arrangement of the belt and'slat of a draper and rivet members, through the medium of which the slat and belt are connected. Fig. 5-isa view similar to Fig. 1, illustrating another embodimentof the invention. Fig. 6 is a detail section taken at right angles to Fig. 5 and illustrating the tubular portion and the'plunger of theupper member comprised in the modifled device, and Fig. 7 is a detail elevation of the o crating-lever of the modified device.

more particularly to Figs. 1 to l thereof, A is the main frame of my novel device. The said frame is preferably, though not essentially, of cast metal and comprises a'base or work-support I having a socket b and an overhanging arm 0, bifurcatedat itsforward end, as indicated by d, and provided at. opposite sides of the said bifurcation with vertically-disposed aperturesc, Fi .2. i H Disposed in t e socket to" the work-support with its upper end flush with the upper side of said supportis a rivet-block or anvil B, and also disposed in the said socket is a coiled s rin O and a rivet-holderl). The sa d o. darin u ar-inf rm andis ranged around the upper portion of the block or anvil B and on the spring C, as shown. In virtue of this construction and relative arrangement of parts it will be noticed that the holder D will retain a rivet on the u per end of the block B after the manner il ustrated and will be forced downwardlyby the upper member of the device, so as to leave the rivet free to pass through the belt of a draper or the like, as shown in Fig. 4. It will also be noticed that when the holder Dis forced downwardly a flange f at its upper end will bring up against the upper. side of the work-' support, and when the upper member of the. device is raised the spring 0 will operate to return the said holder D to its normal tion. (Shown in Fig.1.) e

E, Figs. 1 and-2, represents the upper riveting member of the device. member E comprises a tubular portion 9., having a truncated taper h at its lower' end and also having a flange i, lateral projections k, Fig. 2, and upwardly-extending guiderods Z, a punch m, disposed and movable vertically in the tubular portion 9 and having a chisel-shaped lower end it, and a coiled spring 1), surrounding thepunch m and interposed posi- The said upper between an abutment thereon and the por' tion g and having for its purpose to return the punch to'and normally hold the same in the position shown. The upper portion of the punch m is disposed in the bifurcation d of the overhanging arm 0, while the guiderods Z are disposed and movable vertically in I J nmrnn STATES PATENT; OFFICE. 1--

the apertures e of said arm. The flange 'i of the tubular portion 9 is designed to permit of the ready removal of the work when the.

same adheres to and moves upwardly-with g the taper portion 71., a prying instrument be- Re erring by letter to said drawings, and

tend to return the member E as a whole to and normally retain the same inthe position illustrated relative to the arm 0.

G is a vertically-swinging lever fulcrumed on the rear portion of the arm 0 and having 5 an opening 0, receiving the portion 9 of-the. member E at a point above the lateral pro-:

upper side of the'overhanging arm a, so as to I00 jections 7c, and H is an operating-lever ful crumed in the bifurcation d of the arm 0 and "having ahead .9, arrangedfto engage the free IIo portion of the lever G, and a handle 13, arranged to engage the upper end of the punch m, as

hereinafter more fully described.

In the practical use of my novel device a rivet is placed on the block or anvil'B and in the holder D, and the fastening member u, complementary to the rivet, is placed on the truncated taper h of the upper member E, Where it will be retained against casual dlsplacement by frictional contact. The slat v is then superposed on the belt to, to which it is to be fastened, and thus relatively arranged the said parts are placed on the upper end of the rivet-holder D. With this done, the level H is swung in the direction indicated by arrow in Fig. 1, when, as will be readily observed, the member E as a whole will be moved downwardly to place the fastening member at in the correspondingly-shaped ap erture of the slat v and the punch m will be forced downwardly, so as to split and upset the rivet in the reduced end of the member a. Incident to the operation just described it will be observed that because of the reduced end of the fastening member u projecting a slight distance through the slat it will operate, in connection with the stem of the rivet, as a cutting-tool, and hence will remove a core from the belt as an aperture is made in the belt by the rivet-stem. 7

As will be readily observed by reference to Fig. 1, the downward movement of the member E as a whole is effected through the medium of the head 8 of the lever II and the vertically-swinging lever G, while the downward movement of the punch m is effected by the handle t of lever H acting directly upon the upper end of the punch 'm. When the lever H is returned to the idle position shown in Fig. 1, it will be observed that the springs F and P will hold the lever G under pressure against the head of lever H, and thereby prevent casual movement of the latter lever.

While I prefer to employ a lower riveting member comprising a block B, a spring '0, and a rivet-holder D, as shown and described, I do not desire to be understood as confining myself to such construction of lower riveting member, as a lower riveting member of any construction compatible with the purposes of my invention may be employed without involving a departure from the scope of my invention as claimed.

It will be gathered from the fore oing that through the medium of my nove device ,a person is enabled to expeditiously and securely rivet the slats and belt of a draper or the like together, and this with the expenditure of but very little effort. It will also be gathered that the device is simple and compact in construction and embodies no delicate parts such as are likely to get out of order or be broken after a short period of use.

Referring now to the embodiment of my invention shown 'in Figs. 5 to 7, A is the main frame. Said frame A comprises a --work-support a, having a socket I) and an overhanging arm 0, chambered adjacent to its forward end, as indicated by d, and provided with a vertically-disposed aperture 1;. The work-support a is shown as equipped with an anvil B, a spring C, and a workholder 1), similar to those shown in Figs. 1 to 4 and before described, which parts constitute a lower riveting member; but I desire it distinctly understood that the said work-support may be provided with a lower riveting member of any other suitable description without involving a departure from the scope of my invention. E, Figs. 5 and 6, is the up per riveting member. This member comprises a tubular portion g, havin a truncated taper h at its lower end and also having a diametrical opening k in its upper portlon and a communicating opening Z in its upper end, and a punch m, disposed and movable vertically in the tubular portion g and having a suitably-pointed lower end a and also having an enlargement p, arranged to hold it against undue downward movement in the portion g. The upper part of the tubular portion 9 is disposed in the chamber d of arm 0 and is provided with a lateral projection Z arranged to bring up against the lower wall of said chamber, While the lower part of said ortion g is arranged and movable vertical y in the aperture 6. H is an operating-leverfulcrumed in the chamber d of the arm 0 and havin a bifurcation c to receive the punch m and also having heads 8 at opposite sides of said bifurcation and a handle t, arranged to engage the upper end of the punch.

The embodiment shown in Figs. 5 to 7 is operated inthe same manner as that shown in Figs. 1 to 4, the movement of the lever II from the position shown by dotted lines in Fig. 5 to the position shown by full lines in said figure serving to move the member E as a whole downwardly, after which the leverhandle 25 bears upon and forces the punch m downwardly. Incident to the movement of said lever H in the opposite direction, the heads .9 thereof acting against the upper wall of the opening is serve to raise the tubular portion 9 of the member E to the osition shown by dotted lines in Fig. 5, w en the lower wall of the opening is acting against the enlargement p of punch m will raise said punch to the position shown by dotted lines in Fig. 5. In the event of the work adhering to the ta ered lower end of the tubular portion g w en said portion is positively moved upwardly by lever H it will be observed. that the arm 0 will displace the work from the said tapered end.

It will be gathered from the foregoing that the embodiment shown in Figs. 5 to 7 is a material simplification of that shown in Figs. 1 to 4 and embodies no springs or other I ing of the said embodiment.

parts likely to get out of order after a short period of use..

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiments of my invention in order to-impart a full,clear, and exact understand- I do not desire, however, to be understood as confining myself to such specific construction and relative arralilifgement of parts, as such changes or cations may be made in practice as fairly fall within the scope of my invention as claimed. 1 I

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-
