ATTACHMENT FOR PNEUMATIG- MAGHINE-BHFETERS.

To all whom it may concern: v Be it known that I, WILEY STARK, a c1t1- zen of the United States, and a'resident of Devils Slide, in'the county of Morgan and State of Utah, have invented a new and Imroved Attachment for Pneumatic Machineiveters, of which the following 1s afu ll,

clear, and exact description.

My invention relates to an attachment to be applied to a pneumatic machine riveter for doing field riveting, shop riveting,and

riveting generally.

The prime object of my inventlon 1s to provide an attachment for appllcation to the front end of-the riveter set and to be man ually held thereto to constitute a forward extension of the riveter, whereby to perform with convenience and despatch, general work nowfiperformed by separate and less efiicient machines, such asthe work of a backing out punch, a cold cutter, a gouge, or.

a diamond point generallyused in cuttin boiler plates or like sheet metal. The nature,

the modes of use, and the advantages of the invention will appear from the following description.

Reference .is had to the accompanying drawings forming part of this specification,

in which similar characters of reference indicate corresponding parts 1n all the vlews, and in which: I

Figure 1 is a perspective view of an attachment embodying my invention, and indicating the application of the tool to a pneumatic machine riveter mdlcated 1n dotted lines the view including, in dotted lines also, a piece of work to-be operated bodying the invention. 50

upon; Fig. 2 is an elevation of the atis a broken front view showing a modified form of the device; Fig. 5 is a vlewof the attachment shown in Fig. 4, but taken at right angles to saidfigure; Fig. 6 is aview similar to Fig. 4, but showing a further modification; Fig. 7 is a viewat right angles to Fig. 6; and Fig. 8 is a fragmentary side view showing the front end of a gouge em- Referring particularly to Figs. 1 to3, the practical embodiment of the invention there,- in illustrated comprises a tool 10, the front end 11 of which. is formed to adapt the tool for use as a backing out punch, that is to say, for forcing out a rivet by exerting pressure against the forward end thereof. At

. axis of the .tool

.the rear end of the tool 10 and in axial alinementwith the working face 11, ahead 12 is formed, which in practice may be given a rivet. I

In order to manually hold the attachment firmly n proper POSltiOIl'OIl the'riveter A, and aga-lnstthe working face of the set the ,tool 10 isprovided with a handle 14 in-" atentedJan. 4., 1916. Application filed January 14,1915. Serial 301.2238.

set'is intendedto operate J upon, that 1s to say,-whether a cone button .head r1vet or a steeple or other character of tegralas at; 13-,with the tool. 10 at a-side' thereof adjacent to the head 12. .The handle 7 extends rearwardly be yond the head 12Iaconsiderable distance,-so

14 is elongated and as to-a'fi'ord am le room to be ras ed b the hand of the g p y operator. The handle ilies essentially parallel" with the longitudinal The rear end of the handle 14' is given such formationv that pressure may be exerted by the hand in a rearward direction and 10, and a depression 15 is against a forward surface of the handle to properly position and sustain the. attachment, so that the set a will have a firm bearing against the'head 12. In the preferred form-the handle is return bent as at 16 at the outer side, thereby presenting at the,

bend a forward surface against which the hand'of the operator may exert a rearward pressure as the fingers of the operator grasp the riveter A and handle 14, as indicated in Fig. 1.- It will be seen that the operation I of the riveter A will exert its blows on the attachment, and if the latter be of a form to constitute, for instance, a backing out punch,

as in Figs. 1 to 3, a rivet may be expedi-- tiously driven out by the operation of the said I riveter.

In a similar manner the invention is employed in a, kit of tools presenting various conformations as to the working front end, whereby workmen, by using the riveting machine -A may perform the operation of cutting off a rivet by a cold cutter while eliminating the, use of a maul; or by employing'a diamondpoint, perform the operation of cutting boiler plates and other sheet metal; and likewise, perform the work of a gouge for gouging and matching holes in plate steel, or other structural steel elements, where there has been a defect in drilling,

and rivet holes are not found to be in exact register, or for other reasns not permitting the free entrance of'a rivet.

In Figs. 4 and 5 the tool is given at the front end the formation of a cold cutter 11. The other elements of thetool are essentially as previously described, there being a head 12 to receive the face of the set a, and a handle 14' integral as'at 13 with a tool to prevent a depression In Figs. 6 and 7 the tool 10 at the front end is given the form of a diamond point, as indicated by the character 11. The elements 12 13 14 and 15 are the same with the other devices, Figs. 1 to 5. By the use of a tool with the diamond point, the cutting of sheet metal or other structural steel elements may be effected with greater rapidity and more efliciency because of utilizing the power of a pneumatic machine riveter, than by the methods usually employed, which involve the .use of smaller, less efiicient and less convenient expedients.

- In Fig. 8 I have illustrated a portion of.

a tool 10 which is given, at the front 11, the form of a gouge for gouging and matching holes in steel plates, or other like elements.

memes It is to be noted that the tools of the kit can be employed on the riveter A without removing the set a thereof.

Having thus described my invention, what I claim as new and desire to secure by, Letters Patent, is:

1. As an article of manufacture, a tool for use on machine riveters, the tool presenting a head to be introduced between the riveter set and the work, and means independent of the said riveter set whereby said head may be held in position on the riveter in position for use.

.2. An attachment for pneumatic machine riveters, comprising a tool having a front working face and formed at the rear end to receive the front end of a riveter set, and an elongated handle on the tool, said handle being offset from the tool and ranging rearwardly therefrom to lie alongside a riveter,

the said handle having a lateral member pre- 1 senting a forward face against which the hand of the operator may bear in gripping the handle and riveter set.

In testimony, whereof I have signed myname to this specification in the resence of two subscribing witnesses.
