DANIEL H. MURPHY, OF HARTFORD, CONNECTICUT, ASSIGNOR OF ONE-HALF TO JOHN S. SMILEDGE, OF SAME PLACE.
SECURING TOOLS TO HANDLES.
SPECIFICATION forming part of Letters Patent No. 291,851, dated January 8, 1884.
Application filed May 10,1863. (No model.)
To a whom, it may concern.-
Be it known that I, DANIEL H. lVIURIHY, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements inMethods of andDevices for Securing Tools to Handles; and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.
Like letters in the figures indicate the same parts.
Figure l is a top View of my device as applied to a hammer. Fig. 2 is a View in longitudinal crosssection of same on line as x of Fig. 1.
My invention relates to the class of devices used for securing tools to handles, and more particularly to those used in hammers, a-Xes, adzes,and thelike, inwliich the handle,inserted in the head of the socket, is split and a wedge compressed in the slit, preferably before the handle is placed in the socket.
The wedges in common use are of iron, wood, or the like hard materials; but my invention consists in using for a wedge ahighlyelastic material-as india-rubber or the likei which is compressed and forced into the slit in the handle, in which it expands and binds the handle against the sides of the tool-socket with a constant pressure.
In the accompanying drawings, the letter a denotes a hammer-head; b, a handle of ordinary material, as wood; I), slits in the end inserted in the hammer-socket, and c a wedge of india-rubber or like elastic material, which is compressed in the slitted end of the handle, which is then forced into the socket in the tool-head. One or more of these wedges may be used in slits in the handle, made transversely in any desired direction 5 but in the form shown in the drawings the wedge forms a cushion which aids materially in the use of the hammer by giving a certain elasticity to the blow-an incidental advantage, but not the main object of my invention.
One special advantage of the rubber wedge is, that when the hammer is used there is no tendency on the part of the rubber wedge to crawl or be forced out from the slit, there being sufficient friction between the surfaces of the wood and the rubber to afford a secure hold, and the constant pressure of the wedge keeps the handle end distended to the full extent of the socket in the tool-head, and takes up any shrinkage caused by the seasoning of the wood.
It is obvious that my invention is capable of many modifications and adaptations in the special art to which it relates-namely, the securing of socketed tools and the like to their handlesand that the form and position of the wedge may be varied without the exercise of invention as long as it is so placed as to expand the slitted end of the handle.
In order to more securely hold the elastic wedges in the slits, I corrugate the faces of the slits or make use of the cavities b, in which the elastic material expands, securely holding the wedge against longitudinal displacement after the handle is inserted in the socket.
I claim as my invention-- 1. The method of securing a tool to its handle, which consists in slitting the end of the handle, compressing in said slitted end a wedge of elastic material, as india-rubber, and then inserting the slitted end of the handle into the handle-socket in the tool, all substantially as described.
2. In combination, a tool having a handlesocket, a handle having a slitted end, and a wedge of elastic material compressed in said slitted end of the handle, whereby the handle is wedged in the socket in the tool, all substantially as described.
3. In combination, tool a, handle I), having the end slits, b, with enlargement b, andwedge c, of rubber or its equivalent, compressed in the slit, all substantially as described, and for the purpose set forth.
DANIEL H. MURPHY.
