RIVET CATCHER.

Application filed June 19, 1920. Serial No. 390,221.

To aZliolzom it may concern:

Be it known that 1, JOHN M. Caravan a citizen of the United States. residing at- Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Rivet Catchers, of which the following is a specification.

This invention relates to improvements in arcasing for cutting tools, as for instance a rivet clipper, whereby the. head which is clipped from the rivet is caught by the easing and thus prevented from striking a nearby workman.

One object of the invention is to provide a casing for the end portion of a cutting tool with a housing formed in the end of the casing to receive the clipped head of a rivet or the like.

Another object of my invention is to provide a rigid casing with a bearing strap or member extending across the open under side of the casing so that the cutting tool can move about a horizontal axis on said bearing member and in this way make it possible for the'cutting end of the tool to pass beyond the casing.

Still another object 0t my invention is to form a rigid casing with flexible side portions and a flexible strap member connecting the edges of the side portions so as to allow the. fiexibleportions to be gripped about the tool and to allow also the required amount of: play for the't'ool as it moves about a horizontal axis on the bearing member in passing beyond the casing end.

A further object is to provide a casing with a metal rigid body portion and a covering of leather or other yieldabl'e material, which projects below the edge of the metal at the bulged end so "as to prevent the rivet head from slipping out between the casing and the tool.

Another object is to secure the yieldable covering to the metal body portion in such a manner as not to interfere with the catch ing of the rivet head in the housing of the casing.

Other forms of structure embodying my invention will suggest themselves to those skilled in the art, but the preferred form will be understood from the following description and claims considered in connection with the accompanying drawings.

Fig. 1 is a side elevation of my invention;

Fig. 6 is a view like Fig.1. 3 showing the relative arrangement of casing and cutting tool after the rivet head has been clipped.

The casing comprises a concave rigid strip 1 of metal or other suitable material, to the outside of which is secured covering members 2 and 3 of flexible material, such as leather; these parts being secured together in any suitable manner, as for example by means of rivets i and 5. The forward end portion of the casing is formed with a dccided bulge as indicated at 9, so as toprovide a housing for the reception of the severed head of a rivet or the like. as illustrated in Fig. 4. The member 2 is separate from member 3 and is riveted along the back of strip 1 as at t so that the side portions 6 are free for flexure. The part 3 of the covering projects below theedge of the bulged portion 9, as indicated at 3 in Fig. With this arrangement the .material ii being yieldable, affords added protection inasmuch as the rivet head catcher accommodates itself to the "irregularities of the material. thus preventing rivet heads and steel slivers from Flying, and furthermore permits the rivet head catcher to be moved forward or backward with greater facility. The rivets tor securing the covering i) to the metal meniher 1. are placedaway from the tront end of the casing. as for instance along the sides "as at 5, so as to avoid any danger of the severed rivet head striking a head of one otthese rivets 5 and glancing out between the casing and the cutting tool as above referred to. Thus the covering 3 is extended back over the bulged end of the member 1. The covering 3 is split and overlapped as at 3 and 3 so as to conform to the shape of the housing. p

A curved strap or bearing member 7 has its endsattached to the side portions 6 in any suitable mannery as for instance by means of rivets 8. This member 7 is located at a point substantially midway of the length of the casing and is adapted to form a bearing means for the cutting tool as it moves about a horizontal axis in order for its cutting end to pass the" end of the casing after the clippii'ig' of the rivet head.

The casing is made sufficiently large to allow the required freedom of moveme-ntof the cutting tool during the clipping operation; the fie. 'ble bearing member '4' allowing suiiicient give as the tool is caused to pass beyond the housing end of the casing. The flexible portions 6 and 7 serve also as a means for holding the casing in proper position upon the cutting tool.

This device is especially adapted for use in connection with a pneumatic gun or other power tool for clipping rivet heads, and as the tool engages the rivet head it bears an angular relation with the length of the casing, as indicated in Fig. 8. Then as the tool clips the rivet head, this angular relation is increased to the extent that the end of the tool passes beyond the end of the cas-- ing as indicated in Fig. 4. The head 11 is caught in the housing 9 and is thus prevented from causing injury.

By providing the angular play between the tool and the casing, it is possible to make the casing rigid and at the same time allow the end of the tool to pass beyond the casing.

This results in a more durable structure. Then with the reinforcement for the housing, it is prevented from being torn by the force of the rivet head as it flies from the rivet. And furthermore the severed rivet head is prevented from slipping past the edge of the housing, as above explained.

' Other advantages will be apparent to those who are familiar with the art to which this invention relates. i

lVhat I claim is:

1. A rivet head catcher, comprising a casing member adapted to be applied to a clipping tool or the like, said casing being open and free of obstruction along its one side, a single bearing means provided between the side walls of said casing, and extending across said open side in such a manner that the cutting tool is free to move about said bearing means on "a transverse axis during the clippingoperation so as to allow the cutting end of the tool to pass beyond the end of said casing as part of the same operation.

2. A rivet head catcher, comprising a rigid bracing member, a covering of flexible material upon said rigid member, said rigid member and the covering therefor together forming a casing for a clipping tool or the like, the side walls of saidcovering throughout part of the length of the casing extending beyond said rigid member and being free for bending, a yieldable bearing member extending between the side walls of said yieldable extensions and adapted for move- .ment toward and away from said casing.

3.
