HIVETING TOOL.

RIVIETING-TOOL.
Application led April 19, 1915.
To all whom t may concern:
Be it known that I, Louis KAMosIs, a citizen of the United States, and a resident of Elyria, in the county of Lorain and State of Chio, have invented certain new and useful Improvements in Riveting-Tools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
a My invention relates to riveting tools, and more particularly to that class of tools which are employed tot'form the head up on the rivet. For example, in some schemes of riveting, a hot rivet is driven by a hammer through the bodies to be riveted together, and a `workman holds.` the tool against the small end of the rivet-as it is driven through, forming a head upon the end of the rivet engaging the tool.
In modern practice, hammers of various types are used, including hand, pneumatic and electric hammers, which strike hard and sometimes very rapid blows, the maximum force of which is especially injurious and sometimes disastrous to the workman holding the heading tool,.while the mean force of the blows, if not entirely harmless, is not dangerous. i
a One of the objects of my invention is to lessen or destroy the injurious effects of the hammer blows upon the workmen, without interfering with the effectiveness of the tool in the riveting operation.
Another object of my invention is to iron out, as it were, the sharp nature of the blows and produce a more 'even and uniform effect upon that part of the person of the workman against which the tool is placed, thus relieving him from the resulting injuries. j
Other objects of my invention and the invention itself will be better understood from a description of an embodiment of my invention.
Figure 1 is a longitudinal section through an embodiment of my invention. Fig. 2 is a detail showing parts of this embodiment.
Specification of Letters Patent.
Patented Apr. 1S, 1916.
Serial No. 22,272.
Fig. 3 is an elevation of the embodiment shown in Fig. 1.
Referring now to the embodiment illustrated 1n the drawing, at 4 is shown the head of the tool which is here made massive, in orderr that by its inertia much of the shock of the blows may be taken up. rihe inertia of this weight also serves to smooth od' the sharp parts of the blows, and more equally distribute the effect thereof. The weight of the head may be varied to meet various con ditions. The bottom head 5 is shaped like the frustum of a cone, the point of the cone being cut off, as shown at 6, and hollowed out, as shown at 7, in any suitable manner, dependent upon the shape desired to be given to the rivet head. Through this frusto-conical part of the head, the blow is transmitted to the main part 4 and equally distributed thereover. The main portion 4 of the head is preferably cylindrical in shape and the top S perpendicular to the long axis of the head. A cylindrical bore is formed in the top of the head, as shown at 9, and the same is provided with thread 10. The upper portion of the head is countersunk, as shown at 11, forming a larger bore concentric with the bore 9. The body portion of the tool is shown at 12 and is preferably cylindrical, and of the same diameter as the main portion of the head 4. The lower portion of the body 12 is provided with a projection 13, threaded, as shown at 14, to cooperate with the threads 10 in the bore 9, in order that the body and head may be securely but detachably connected together, thus enabling me to use the head with any suitable body, or the body with any suitable head.
The upper part of the body is bored out, as sho-wn at 15, the upper part of the bo-re 15 being of greater diameter, as shown at 16, than the lower part 17 thereof. A shoulder 18, between these sections of the bore 15, is inclined with respect to the long axis of the body. Perforations 19 and 20 are provided in the walls of the bore 16 for the insertion of a pin 21 through these holes, and the bore 16. rlhe shoulder piece is shown at 22, which is adapted to be rested against the body of the workman. In practice, this is generally held against the workmans shoulder. The body of the shoulder piece is provided with a plunger 23, preferably cylindrical in shape and suitable for insertion into the bore 17. The end of the plunger may be cut away, as shown at 24.
An elongated slot 25 is cut through the plunger of substantially the same width as the diameter of the pin 2l, but much longer.
A collar 26 is mounted on the plunger against which a coil spring 27 abuts, the upper portion of the spring engaging this collar and the lower portion engaging the shoulder 18 when the parts are assembled and in operation. The slot 25 determines definitely the movement of the head and body of the tool with respect to the shoulder piece, and should be of suflicient length to permit the spring 27 to absorb the surplus force of the blows of the rivetinof hammer and to assist in smoothing oii7 Jhe severe part of these blows, without reducing the ei'liciency of the tool and properly heading the rivet. This spring should yield for the severe parts of the blows, but be stiii3 to transmit the mean or effective part thereof. rIhe relation of these partsmay be determined for each particular use, and be properly proportioned and arranged. Coperating shoulders 30 and 3l are provided on the parts l2 and 22, respectively, to limit and positively check the movement of the part 12 with respect to the part 22.
The operation of my device is as follows: The tool is held with the depression 7 over the head of the rivet, and the shoulder piece is placed against the shoulder of the workman who holds the tool in his hands. The hammer applies sharp rapid blows to the rivet, which must be absorbed by the workman until the rivet is properly headed. In the application of my invention, the sharp, injurious parts of the blows are absorbed and smoothed over by'means which I have employed, without in any way destroying the effectiveness of the more substantial part of the blows which eiiect the operation upon the rivet.
I have illustrated this embodiment of my invention for the purpose of better describing the same. I do not wish to be limited to such embodiment, as it will be apparent that many departures maybe made `from the particular form shown therein and the details thereof, without departing from the spirit of my invention.
I claim rl. In a riveting tool, the combination of a relatively massive head having a frustoconicalshaped bottom with a depression in the tip for engaging the head of the rivet, a threaded bore in the top of the head, a body portion having a threaded projection adapted to coperate with the threads in the bore in the head of the too-l for connecting the head and body together, a bore in the top of the body of the tool, a shoulder in said bore, a shoulder piece, a projection on said shoulder piece, a collar on said projection, a spring between the collar on the projection and the shoulder in the bore in the body of the tool, an elongated slot in the shoulder niece, the walls of the bore in the body of the tool being provided with diametrically opposite openings, and a pin eX- tending through said openings and the elongated slot in the shoulder piece.

a relatively massive head, a body portion, means to connect the body portion to the head, the head being provided with a bore at its top, a shoulder in said bore, the head being provided with a pair of diametrically opposite openings in the top of the bore, a shoulderA piece provided with a plunger, a collar on the shoulder piece, an elongated slot in the shoulder piece, a pin passing through the elongated slot and the openings in the top of the body piece, a spring between the shoulder in the bore in the body and the collar on the shoulder piece, and coperating shoulders on the body piece and shoulder piece for positively checking the movement of the body piece.
5. In a riveting tool, the combination of a relatively massive rivet engaging portion, a shoulder engaging portion, means for con- 4. In a riveting tool, the combina-tion of necting said portions together including an elongated slot in one portion and a trans- Verse pin in the other portion passing therethrough, said parts when so connected t0- gether adapted to reciprocate one with respect to the other and a spring between said portions yielding to the maximum force of K the blows of the riveting hammer, said LOUIS KAMOSIS.
