copartnership Application November 1, 1935, Serial No. 47,893

3 Claims.

This invention relates to hand tools and particularly to hand tools for performing riveting, punching operations and the like.

It is an object of the invention to provide a tool of the class referred. to the parts of which can be so cheaply made and so cheaply assembled that the tool can be sold to the consumer at so low a price as to make it available to the individual user who has heretofore been unable to afford the price of a tool of this class.

Another object is to provide tool of this class which can be easily and cheaply made and assembled but which will be simple and durable in operation.

Another object is to provide, in a tool of the class referred to, improved means for yieldably supporting a movable riveting element.

Another object is to provide generally an improved tool of the class referred to.

Other objects will be apparent to those skilled in the art to which my invention appertains.

My invention is fully disclosed in the following description taken in connection with the accompanying drawing, in which:

Fig. 1 is a side elevational view with parts broken away of a preferred embodiment of my invention;

Fig. 2 is a sectional view taken from the plane 2-2 of Fig. 1;

Fig. 3 is a fragmentary elevational view taken from the direction of the arrow 3 of Fig. 1;

Figs. 4 and 5 are, respectively, side elevational and end views of a tool element which I may employ instead of that illustrated in Fig. 1;

Fig. 6 is a View illustrating the tool of Fig. 1, performing an operation with the tool element of Figs. 4 and 5;

Fig. 7 is a fragmentary sectional view taken from the plane I of Fig. 1.

Referring to the drawing, I have shown generally at I a main frame comprising a base 2 having on the lower side thereof a tongue 3' and shoulders 44. The tongue 3 is adapted to be inserted between the jaws of a vise shown at 45 5 in broken lines, Fig. 3, and clamped th-erebetween to support the device, the shoulders 4-4 resting upon the jaws to position the device.

A yoke 6, preferably T-form in section, having a rearwardly extending rib I, rises from the base 50 2 and has a bearing 8 thereon above the forward end of the base 2. The base 2, yoke 6 and bearing 8 are preferably all formed integrally as for example in a casting. Extending entirely through the base is a bore 9 and aligned there- 55 with is a bore ID in the bearing 8.

In the bore 9 is preferably inserted the shank ll of a lower riveting tool |2 having a collar l3 resting on the base when the shank II is in the bore 9, and provided as at l4 with an elevated portion upon which a riveting operation may be performed.

In the bore I is reciprocably mounted a cylindrical riveting tool I5 which may have a conical point IS on the lower end to facilitate the riveting operation and at its upper end I! may project upwardly beyond the bearing 8. Means to be described is provided to'support the tool |5 in the bearing but permit it to be driven downwardly when struck a blow with a hammer upon the upper end Ill; and as will now be apparent, by such action, a riveting operation may be performed, for example on a rivet |8 resting upon the lower riveting element l2 and in a piece of work IQ, for any purpose. As illustrative of such uses is the riveting of rivets in the operation of relining brakes for vehicles.

The bearing 8 has a pair of openings 20 20 at opposite sides thereof opening into the bore I0, opposite sides of the; tool I5 being exteriorly exposed in the opening 20.

A hairpinform or U-form spring 2|, preferably made from wire, is provided straddling the rib I of the frame and at its free ends as shown at 2222, Figs. 2 and 7, resiliently gripping or pinching therebetween opposite sides of the tool I'i. The tool is thus supported in the bore ID. If the tool tends by gravity to slide downwardly in the bore the ends 22-22 of the spring will be prevented from sliding by engagement thereof with the sides of the openings 2020 and the frictional engagement between the ends of the spring and the tool will prevent it from sliding and will support it.

Onthe other hand, however, the tool I5 may be grasped between the thumb and finger of the operators hand and it will yieldably slide in the bore to position it above the work l9; and in any position to which it is reeiproeably moved, it will remain by the friction provided for as above described.

To support the rear end of the spring 2| and to position the free ends 2222 thereof, the closed end portion 23 of the spring may be lodged in a notch 24 in the relatively thin outer edge of the rib I.

The device thus far described will be seen to be relatively simple, consisting only of the frame I and the two tools or tool elements l2 and I5, and the spring 2|; but to insure that the production cost of the device will be as small as possible, provision is made to facilitate assembly of the parts particularly the spring 2| with the frame. To this end, the openings 20 have a groove or grooves 25 formed in the side of the head 8 and leading into the apertures, and the spring 2| is formed of sufiiciently heavy wire so that when spread apart to engage the opposite sides of the tool shank [1, it will exertthe necessary suspending friction and at the same time before it is assembled in working position and the ends of the wire are at their greatest proximity to each other, they will still be spaced apart sufliciently to easily be straddled over the edge of the rib 1. With the'spring thus constructed, the ends thereof may be conveniently straddled over the rib 1 at a point such as that at 26 in which the spring is diagonally disposed so that the greater part thereof may extend beyond the rib l and be engageable by the hand of the assembler. The ends of the spring are then slid into the'grooves which lead them into the openings 20; then the outer end of the spring is rocked around to the notch 24 and thrust into it. The successive movements of the closed end of the spring to assemble it are indicated by the arrows 21 and 26, a final movement not indicated being required to finally. lodge the closed end in the notch 24.

By this process of assembling, a much stronger spring can be employed than otherwise because a stiff spring will cause delay in the operation of assembling it'with the rest of the tool, in the absence of means to guide it to its position.

Upon removing, the lower riveting element l2, the tool may be used to punch holes or to knock out rivets, the latter operation being illustrated circular section punch or the like and that the same may be operated by a hammer blow on the end thereof as described for the tool Hi.

My invention is not limited to the exact details of construction illustrated and described. Changes and modifications may be made within the spirit of my invention without sacrificing its advantages and within the scope of theappended claims.

I claim: 7

1. In a tool of the class described, a C-form frame comprising an outwardly extending rib having an outer edge portion, and a bearing having a cylindrical bore therein, the bearing having opposite openings provided in the wall of the bore, the bore receiving a cylindrical tool shank reciprocably therein, a notch in the outer edge portion of the rib, a U-shaped spring having the closed end engaged in the notch and having its legs frictionally gripping therebetween through the openings opposite sides of a tool shank in the bore.

2. In a tool of the class described, a C-for'm frame comprising an outwardly extending rib having an outer edge portion, and a. bearing having a bore therein, the bearing having opposite openings provided in the wall of the bore, the bore receiving a tool shank reciprocably therein, a notch in the outer edge portion of the rib, a U- shaped spring having the closed end engaged in the notch and having its legs frictionally gripping therebetween through the openings opposite sides of a tool shank in the bore.

3. In a tool of the class described, a C-form frame, a head having a bore therein, the head having an opening in the wall of the bore, the bore receiving a tool shank reciprocably therein, a notch in the outer convex portion of the C-form frame, a U-shaped spring having the closed end engaged in the notch and having its legs disposed on opposite sides of the head and having a portion of a leg in said opening frictionally engaging, through the opening, a side of a tool shank in the bore.
