OPERATING CATCH IN TOOL-HOLDERS.

Specicaton of Letters Patent No.v10,853, dated May 2, 1854.

To all 'whom t may concern Be it known that I, JOHN ALLENDER, of New London, in the county of New London and State' of Connecticut, have invented vcertain new and useful Improvements in Sockets to Hold Tools; and I do hereby declare that the same are described and represnted in the following specifications and drawings.

To enable others skilled in the art to make and use my improvements I will proceed to describe their construction and use referring to the drawings in which the same letters indicate like parts in each of the figures.

Figure l, is an elevation of the socket with the shank of a tool in it. Fig. 2 is an elevation of the end of the socket. Fig. 3, is a section of Fig. 2, cut through the line z z.

In these drawings A is a socket or a portion of a bit stock, with a hole B in the end to which the shank C of a tool or bit is fitted; which shank is provided with a score e for the end of the catch f which traverses in the slot and score 7L in the end of the socket A. The catch f is provided with a projection z' fitted to the eccentric score k in the face plate G which plate is fitted to the end of the socket A and provided with a rim or flange m which surrounds the end of the socket and is burnished over the rim or iange of the socket as represented in Fig. 3, to hold it on, and at the same time allow it to mo-ve freely on the socket when it is desirable to draw back the catch f, and release theshank C or force it forward and fasten the shank-C in the socket A; the eccentric groove or score 1c acting upon the projection z' of the catch f, as the face plate Gr is turned by seizing it with the hand; and the edge of the plate and the outside of the flange may be milled or scored to prevent the hand from slipping upon it.

I contemplate that the face plate Gr may be held against the end of the socket by countersinking the hole in it and riveting over the end of the socket A which projects through it at y). Or there may be some circular slots in the face plate for screws to be put through and screwed into the end of the socket to hold it on, so as to dispense with burnishing over the edge of the iange m, and the ange also if desirable.

I am aware numerous sockets have been devised to hold tools, and also many devices to hold the tools in the sockets, most of them are either expensive to make, inconvenient to use, are complicated, consisting of many pieces, or donot hold the tools well after they are inserted, so that something simple, cheap, convenient to use and that would hold the tools well and firmly has long been wanting.

The object of my invention is to supply this want, by furnishing a more simple socket consisting of but few pieces, that is convenient to use and will hold the tools firmly, besides being far cheaper and a much better article than those heretofore made.

What I claim as my invention and desire to secure by Letters Patent in the above dee scribed socket is- The face plate with an eccentric groove or slot `in combination with the sliding catch, with a projection fitted to said groove and so arranged as to traverse the catch by turning the plate substantially as described.

JOHN ALLENDER.
