April 14, 1942. A. D. JONES I HANDLE FASTENING DEVICE Filed March 51, 1941 NTOR ' ATTORNEYS Patented Apr. 14, 1942 UNITED STATES PATENT ,oFF cE Alfred D. Jones, Pemberton, N. J. Application March 31, 1941, Serial No. 386,181
This invention relates to handle fastening devices for tools, and its primaryobject is to provide a device that is designed for a tool having a head which includes a tapered eye or socket and a handle having a tapered outer end portion fitting the socket to set up a wedging action therewith, such as for example a pick, grub hoe, mattock or the like, and my device is of flat ring like formation to surround and fit the handle for engagement with the inner shoulder of the socket portion of the head, and includes means about the inner periphery thereof to penetrate the handle when the device is driven against said shoulder, so as to cooperate with said wedging action to prevent any possibility of casual removal or displacement of the head with respect to the handle.
A further object is to provide a handle fastening device that is simple in construction, easy to apply, inexpensive to manufacture and extremely efficient in use and. service.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be here.- inafter fully described, illustrated in the accomtion.

plain but they may be beveled to provide cutting V shaped penetrating teeth 2, slightly bent for dis posal at an angle beyond theouter face of the body, as best shown in Figure 4, and it will be understood that the shape, size and number of teeth may vary, providing theyhavepenetrating points 3, asthe essential, feature of the device is for the teeth to set up abitingengagement The teeth are shown as being edges.
From the above description and the disclosure in the drawing, it is believed that the use of my device will be obvious, but it might be mentioned that the head of the tool is first applied to the handle in the usual manner, that is from the hand gripping end thereof and is disposed in contact with the enlarged tapered outer end por- The device with the teeth outermost is then applied to engage or substantially engage the inner shoulder of the socket portion of the head, thence another tool head or member having a socket similar to the first tool head is appanying drawing and specifically pointed out in the appended claim.
In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding,

Figure 3 is aview of the device per se.
Figure 4 is a sectional view taken approximately on line 4-4 of Figure 3, looking in the direction of the arrows. I
, Referring to the drawing in detail, it will be noted that I have illustrated my device as being used for fastening the head A of a mattock to its wood handle B, but it will be obvious that it can be used on any kind of tool including a socketed head for wedging engagement with its handle.
The device ismade into a single piece from relatively thin plate or sheet metal to provide a relatively wide ring like body I which in the form shown'is oval shape to have abinding fit with thehandle B at the juncture of the enlarged course then removed.
plied to the handle, with the outer shoulder of the socket portion of the latter tool head or member innermost, and is given a hammering action against the device, thus it will be seen that the first tool head is driven in positive wedging' engagement with the handle and the teeth are caused to penetrate the handle, so as to cooperate with the wedging action and thereby prevent any possibility of casual removal or displacement ofthe first, tool head from the handle. The second tool head or member is of Itis thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.
What I claim is: a g A handle fastening device fora tool provided with a head having a tapered socket portion and a handle having an enlarged tapered outer. end
, portion fitting the head to set up a wedging at:-
tion therewith, and said device comprising a relatively wide thin oval shaped plate like ringto fit and surround the handle for engagement with the inner shoulder of the socket portion, and substantially triangular shaped teeth formed on i and extending from and about the entire inner respect to the handle.
periphery of the ring at a slight angle beyond the outer face thereof to penetrate the handle for cooperation with the wedging action to prevent casual removal or displacement of the head with ALFRED D. JONES.
