CARL A. ELMSTROM, OF WORCESTER, MASSACHUSETTS.
RIVETINGr-MACI-IIVNE.
Specification of Letters Patent.
Patented Mar. 30, 1920.
Application filed May 22, 1919. Serial No. 298,934.
To all whom it may concern.'
Be it known that I, CARL A.` ELMs'rRoM, a citizen of the United States, residing at )Voi-cester, in the county of )Vorcester and State of Massachusetts, have invented a new and useful Riveting-Machine, of lwhich the following is a specification.
This invention relates to a machine for performing riveting operations, being espe cially designed for riveting a cross handle to the end of a rod but also adapted to perform a variety of riveting operations upon different objects and materials.
The distinctive characteristic of my inventioii is the provision of mechanism by which the riveting is performed with a rolling action instead of by the usual hammer action.
In the preferred embodiment, my invention comprises a roller mounted for rapid reciprocation and means for causing the roller and work to forcibly engage each other.
Other features of my invention relate to devices for holding the work against the alternating side thrust of the roller, and to devices for rapidly reciprocating the roller.
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.
A preferred form of my invention is shown in the drawings, in which- Figure 1 is a front elevation of the machine;
Fig. 2 is a vertical sectional view taken along the line 2-2 of Fig. l;
Fig. 3 is a detailed section taken along the line 3 3 in Fig. l; and
Fig. 4 shows a sample of the work performed by the machine.l
Referring to the drawings, my improved riveting machine comprises a frame 10 which may be rigidly secured to a bench or table in any convenient manner. A slide 11 is mounted below the upper member of the frame 10 and is supported for reciprocating movement by guides 12 and 13, as shown in Fig. 1. A roller 14 is pivoted at 15 in the slide 11, the roller being preferably formed of hardened steel.
A drive shaft 16 ismounted in bearings at the rear side of the frame 10 and supports an eccentric 17 encircled by one end of a link 18, the front end of the link being pivotally connected at 19 to the slide 11. The
This particular machine is designed for riveting a cross handle 22 to a rod 23 and l willnow describe the devices for holding the handle in position, and for pressing the handle upward against the reciprocating roller. i
The lower end of the rod 23 is supported in a socket'or plunger24 vertically movable in a fixed bearing 25 and provided at its lower end with a roll 26 adapted for engagement by a cam 27 mounted on a crossshaft 28. The shaft 28 is supported in fixed bearings in the frame 10 and is provided with an actuating handle 29 as shown in Fig. 1. By rotating the cam 27 by means of the handle 29 the plungerl 24 may be raised, thus forcing the rod 23 upward against the reciprocating riveting roller 14. Guide flanges 30 facilitate the insertion of the rod 23 in the plunger 24.
Special provision is necessary to offset the forward and rearward thrust of the riveting roller upon the upper end of the rod 23 and for this purpose I provide cross-bars 31 and 32, as shown in Fig. 3, to receive the rod 23 and to limit its rearward movement.
A gate or latch 33 (Figs. 1 and 2) is mounted to slide between the cross-bars 31 and 32, and is provided with a portion 33a (Fig. 3) adapted to be advanced between the front side of the rod 23 and the inner portions of the bars 31 and 32 thus preventing forward or rearward movement of the rod 23 during the riveting operation.
The gate 33 is actuated by means of a cam or eccentric 34 (Fig. 1) mounted on a cross shaft 35 and provided with a handle 36. The eccentric 34 is positioned in a rectangular framework 37 engaging the eccentric on two sides thereof and connected by a rod 38 to the gate 33. By moving the handle 36 the gate may be readily moved to operative or inoperative position as desired.
The operation of the machine is exceedingly simple and will be apparent from the description of the machine. The rod 23 with the cross-handle 22 loosely placed thereon, is inserted in the machine with its lower end in the socket 24, and the gate 33 is then moved crosswise to close the openings in the cross bars 31 and 32 and thus prevent displacement of the rod 23.
The roller 14 is then rapidly reciprocated and the rod 23 is forced upward by means of the handle 29 and the cam 27 until the upper end of the rod 23 has been rolled down from the shape shown in dotted lines in Fig. il to the shape shown in full lines in said figure. The operation is performed with considerable rapidity and the results attained are very satisfactory.
Having thus described my invention it will be evident that changes and modifications can be made therein by those skilled in the art, without departing from the spirit and scope thereof as set forth in the claims, and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is 1. A riveting machine comprising a work support, a freely rotatable roller, means to continually impart short rapidly repeated vibratory linear movements to said roller,
and means to cause relative movement of the work and roller toward each other.
2. A riveting machine comprising a frame, a slide mounted in said frame, a roller supported by said slide, a driving shaft, means to rapidly and continuously rotate said shaft, an eccentric on said shaft having a relatively short throw, a link connecting said eccentric to said slide whereby said slide and roller are given rapidly re peated, short, vibratory, linear movements effective to deliver a great number of successive light blows to the work, a support for the work, means to move said support vertically, and means to prevent horizontal movement of the work with said roller when engaged thereby.
In testimony whereof I have hereunto aflixed my signature.k
