CALVIN LEVI RAINS, OF JOPLIN, MISSOURI.

COMBINED RIVET DOLLY AND HOLDER.

Application filed January 5, 1915. Serial No. see.

To all whom it may, concern Be it known that I, CALVIN LEVI RAINS, a citizen of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Combined Rivet Dollies and Holders; 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.

My invention relates to new and useful improvements in combined rivet dolly and holder, and my object is to provide a device to be held against the headed end of a rivet, while the opposite end thereof is being upset.

A further object is to provide a magnet in unison with the dolly for holding the rivet while the first blows are delivered thereto in the upsettin operation. And a further object is to provide means for attaching the rivet holder or magnet to the dolly.

Qther objects and advantages will be here inafter set forth and more particularly pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application, Figure 1 is a perspective view of the device ready to be applied to use. Fig. 2 is a perspective view of the dolly with the rivet holding device removed. Fig. 3 is a :)erspective View of the magnet or rivet holding device, showing a Fig. l is a perspective view of the clamp employed in securing the holder to the dolly, and Fig. 5 is a perspective view of a screw employed for locking the clamp and holder in engagement with the dolly.

Referring to the drawings in which simi-.

lar' reference numerals designate correspon ding parts throughout the several views, 1 indicates the dolly or riveting bar, which is adapted to be grasped by the hand and held in engagement with the headed end of the rivet while the opposite end thereof is being upset, the contact face 2 thereof being preferably flat to form a firm base for the head of the rivet, and if desired, the walls of the dolly adjacent the face 2, may be beveled or chamfered as shown at 3 so that the end of the dolly may be introduced into a narrow space.

A portion of the upper face of the dolly Specification of Letters Patent.

is cut away to form a flat base i and a shoulder 5 to receive the rivet holding device or magnet 6, the magnet resting edgewise on the base and having its rear end resting against the shoulder 5.

The magnet is formed preferably by bending a piece of flat metal in substantially oval-shape, the free ends 7 thereof being extended in a straight line forwardly and parallel with each other, said ends 7 being introduced between the lugs 8 at the forward end of the base i, said lugs holding the ends against spreading movement, at the same time being a sufficient distance apart to allow the ends 7 to remain in spaced relation.

The magnet is locked in position on the base by introducing a clamp 9 over the upper edges of the parts of the magnet, said clamp having channels 10 to receive said edges, the clamp being locked in position by introducing a screw or the like 11 through an opening 12 at the center of the clamp and into a threaded aperture 13 in the dolly bar, thus securely locking the magnet in position on the base portion of the bar.

In applying the magnet to use, a rivet 1% is placed against the forward ends of the end sections 7, and owing to the magnetic influence of the magnet, the rivet will be held in engagement therewith until it is introduced through an opening and two or three blows given the free end of the rivet to partially upset the same, and in view of the fact that a slight upward pressure is directed against the end of the dolly bar, the rebound from the blows delivered to partially upset the end of the rivet will result in bouncing the end 2 of the dolly bar into engagement with the head of the rivet, when the upsetting process can be completed and in view of the fact that the base of the magnet is seated against the shoulder 5, the initial blows to the rivet will not in any way affect or injure the magnet.

This device can be used in the lighter riveting work and in view of its simplicity can be readily and cheaply manufactured.

What I claim is 1. A dolly bar, comprising a bar, and a magnet upon a side of the bar, the active end of the magnet being substantially flush with the end of the bar.

2. A dolly bar construction, comprising a dolly bar proper, having a seat formed near ment with the dolly bar.

In testimony whereof I have signed my name to tlns specifieatmn in the presence of 1) two SUbECllblIlg wltnesses.
