TOOL FOR PNEUMATIC BIVETERS.
Application filed m 12,
l '0 all whom it"may concern:
Be it known that I, JOHN MASON, a citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Tools for Pneumatic Riveters, whereof the following is a specification, reference being had to the accompanying drawings.
The invention relates to tools for pneu-' matic riveters or similar implements, and its purpose is to provide tools of this type, which are of utmost sturdiness and prove of maximum efficiency under the severe strains of usage to which they are subjected in practice.
I-Ieretofore, such tools were formed with integral shanks of a lesser diameter than the body of the tool proper, and on account of the blows of the hammer piston being directly transmitted through these shanks, considerable trouble has been experienced through fracture and breakage thereof, thereby involving serious losses in plants Where a great number of this class of devices are employed. I
In order to overcome this diliiculty, I have entirely eliminated the shanks above referred to, and the tools constructed according to my invention. are substantially of an even diameter throughout and preferably of larger cross sectional area than the co-operative hammer pistons of the tools with which they are intended to be associated.
The structure by which I attain the results above pointed out will be best understood from the description which follows.
In the drawing, I have shown view partly in elevation and partly in axial section, of the muzzle of a pneumatic riveter, conveniently embodying my invention.
Referring more in detail to the illustration, 1, indicates the muzzle end of the riveter having the usual axial bore 2, for the guidance of the hammer piston 3. The mouth of the muzzle is of larger bore than that of the muzzle proper for the accommodation of the riveting tool 5, which is preferably formed with a beveled upper end 6, adapted to co-operate with a correspondingly sloped shoulder 7 which serves as a limiting stop for the tool in an inward direction. The tool 5, is of an even diameter, throughout except for a slight peripheral recess 8, approximately midway of its length. The tool is normally retained in 1919. Serial No. 310,409.
the riveter by a holder sleeve 9, which is removably secured to the muzzle 1, and its conical lower portion 10, is slitted at intervals as indicated at 11, so as to yieldingly maintain the ends 12, of the prongs thus formed, in the peripheral recess 8, of the tool. These ends are rounded as shown so as to yield under moderate pressure to permit the ready interchanges of tools, but ordinarily offer sufficient resistance in cooperation with the upper shoulder 13, of the recess 8, to normally limit the outward movement of the tool.
The tool herein shown is of the style ordinarilyknown as a rivet set of the button head type by reason of having in its outer end a spherical depression 15, which in operation, determines the shape of the rivet head. In practice, however, the equipment for the riveter includes various types of tools other than that chosen in the present instance merely for convenience of illustration. According to my invention, these various tools are all of the characteristic con-- figuration hereinbefore set forth, so as to be readily interchangeable.
In order to preserve the uninterrupted continuity of the riveter muzzle, I prefer to reduce the end of the same to accommodate the holder sleeve 9, as clearly shown in the illustration.
Having thus described my invention, I claim:
A tool for pneumatic riveters and the like consisting of a solid body or metal adapted to extend into the riveter barrel. and of substantially even diameter throughout except for a shallow encircling, circumferential recess for cooperation with the tool-retaining device of the riveter, and having on its butt end an impact-receiving: surface of reduced diameter sustained by immediately circumjacent and subjacent unbroken and uniformly tapering enlargement of the butt to full size, so that the stress and vibration of impact are freely diffused and local distress or fatigue of the metal from abrupt change of contour-is avoided.
In witness whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this tenth day of July, 1919.
JOHN MASON.
