' The invention relates to that type of jam riveters which comprise a yoke having a rivet set rigidly attached to the outer end of one of its arms and a pneumatic hammer riveter attached to the outer end of its other arm, the hammer riveter being constructed to be moved longitudinally toward the rivet setdurinv a riveting operation.
The object of the invention is to provide a jam riveter of the character explained with a simple and effective means for clamping Work pieces together While being riveted.
The invention is illustrated in the accompanying drawings of which Fig. 1 is a .combined side and longitudinal central sectional view of a jam riveter; and Fig. 2 a longitudinal central sectional view to enlarged scale of the parts of the riveter which coopcrate to drive the rivet.
As illustrated in the drawin s, jam riveters of the type contemplated erein comprise a yoke having the outer end of one of its arms 1 provided with a rivet set 2, which for convenience may be supported in a dolly bar 3 rigidly clamped to the yoke. The other arm 4 of the yoke has attached to it a pneumatic hammer riveter including a barrel 5, movable longitudinally toward and from the rivet set 2, and containing a hammer 6 at its outerend and a piston 7 back of the hammer. In the operation of the hammer riveter, piston 7 is reciprocated within barrel 5 by causing compressed air to low alternately to its opposite ends, the piston during such'reciprocation striking the inner end of hammer 6 which in turn upsets the shank of a rivet 8 a ainst which the outer end of the hammer stri es. The means for reciprocating the (piston forms no part of my invention, an accordingly is not shown. Various valve arrangements for this purpose are Well known in the art, and any of them may be used in the practice of the present invention.
The hammer and piston-containing barrel 5 is mounted for longitudinal movement in a casing -l0 which is rigidly clamped to yoke arm 4. A chamber 11 may be formed between` the end of the casing and the inner end of barrel 5 into which compressed air may flow through a suitable conduit 12 to cause the barrel to move forwardly. This construction is also well known and commonly used in jam riveters, and is illustrated merely as an example of one of the various means that may be used to move the barrel forwardly toward rivet set 2.
As stated, the entirel riveter thus far ex- Elained is well known. V Various means have een heretofore suggested, and some have been used, for clamping pieces of work together during a riveting operation. Some of suchmeans are independent of the actual riveting mechanism, that is to sa independent of the hammer riveter and t e rivet set mounted on the outer ends of the oke arms, and others are formed as a part o the hammer riveter. In the latter case, however, l
the clamping means include a part or parts which are ,movable independently of, and relatively to, the hammer barrel, and the inclusion of such means in hammer riveter so complicates their constructions that they have not been found practical for use.
According to this invention, there is firmly attached to the uter end of the hammer barrel a sleeve which is in ali nment with the hammer barrel and pro'ects eyond the outer end of the hammer. uri'ng a riveting operation the outer end of this sleeve surrounds the shank of a rivet, and by reason of the pressure applied to move the hammer barrel forwardly, the sleeve firmly clamps work pieces together during the riveting operation. This construction, and its consequent operation are made possible by reason .of the fact that the pistons of hammer riveters may move, and in actual practice do move, forwardly variable distances with the hammer barrel before their return strokes begin. Having further reference to the drawings, the outer end of barrel 5 is shown( as beingv provided with a sleeve 15 which may be formed integrally with the barrel, or otherwise attached to it. Preferably, however, the sleeve is merel slipped upon the end of the hammer barrel7 and held firmly thereon by a spring 16 acting between the sleeve and yoke arm 4. This spring resists the forward movement of the hammer barrel and effects its'rearward movement after the completion of a riveting o eration. The sleeve 1s preferably enlarge interiorly adjacent to the end of the hammer barrel to receive an enlarged portion or flange 17 formed on hammer 6, and to permit of longitudinal movement of the head within the sleeve enlargement. The outer end of the sleeve is shown as clamping between it and the rivet Set 2 a plate A18 and an angle 19 which form yindicated in Fig'. 2, its outer end the hammer moves the hammer forwardly sleeve bein as the rivet becomes gradually upset, the enlarged portion of the inner end of the of suicient lenth to permit this forwar movement of the ammer. The position of the hammer at theend of av riveting operation is indicated in Fig'. 1. During the entire riveting operation the sleeve firmly clamps the work pieces together, and furthermore, the construction is such that flange y1i? is so retained in the enlarged inner portion osleeve 15 that the hammer cannot be shot out of the barrel or sleeve in case reciprocation of the piston should commence before the end of the hammer is placed a ainst the end of a rivet shank.`
It wil be observed that the invention affords a. very simple means for clamping work pieces and for holding the hammer in axial alinement with the rivets while they are being riveted, and which in no way complicates the construction of a hammer riveter. The effectiveness of the invention has been amply demonstrated by its use in actual practice.
I claim as my invention:
1. In a jam riveter, the combination of a yoke comprising a pair of arms, a rivet `set rigidly borne by one yoke arm and a hammer riveter mounted on the other yoke arm, said riveter including a single barrel in axial alinement with the rivet set and slidable in the yoke arm, means for forcing said barrel toward the rivet set, a work clamping sleeve firmly seated on the inner end of the hammer barrel having an annular -rivet and with a larger face in axial alinement with the rivet set and normal to such axis, provided with a clearance bore for the u set head of the re intermediate said face and the end of the hammer barrel, a hammer having portions tting the hammer barrel and the clearance bore of the clamping sleeve and having a collar in the larger intermediate bore of said sleeve, and a reci rocating piston back of and adapted to stri e the inner end of the hammer.
- 2. In a jam riveter, the combination of a yoke comprising a pair of arms, a rivet set rigidly borne by one yoke armand a hammer riveter mounted on the other oke arm, said riveter including a single barrel in axial alinement with the rivet set and slidable in the yoke arm, means for forcin said barrel toward the rivet set, a wor l clamping sleeve firmly seated on the inner end of the hammer barrel having an annular face in axial alinement with the rivet set and normal to such axis, provided with a clearance bore for the upset head of the rivet and with a larger bore intermediate said face and the end of the hammer barrel,y
a hammer having portions fitting the hammer barrel and the clearance bore of the clamping sleeve and having a collar in the larger intermedlate bore of, said sleeve, a
reciprocating piston back of and adaptedv setting of a rivet. l
In testlmony whereof, I sign my` name.
