' l Specification of Letters Patent.

Patented Nov. 21, ieie.

Application filed August 18, 1915. Serial No. 46,116.

-To all whom it may concern Be it known that I, Louis C. SoMMnR, Sn, a citizen of the United States residing at Jersey City, in the county ofHudson and State of New Jersey, have invented new and useful Improvements in Tool-Handles, of which the following isa specification.

The present invention relates to improvements in tools, especially to handles there for, an object of-the invention being to pro: vide a handle having means whereby one of any number of head members may be removably and securely connected thereto.

With the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts, set forth in the following specification and falling Within the scope of the appended claim.

In the drawings: Figure 1 is a view of a tool constructed in accordance with the pres= ent invention, Fig. 2 is a sectional view illustrati the manner in which the fulcrum mem er vas'well as a hammer head may be removably connected with the handle and, Fig. 3 is a perspective view of one of the removable heads.

In carrying out my invention Ipropose to provide a handle with means whereby any number of various sized and kinds of hammers, hatchet heads or the'like, maybe removably secured thereon, and while in the drawings the said removable members are in the nature of hammer heads, it is to be understood that other devices may be employed with equal efliciency if desired.

Each of the devices, however, includes a depending or socket portion ;1 which has its bore opening through the head of the tool, and the said bore is of a size suflicient to receiv'e'one end 2 of a handle 3 constru crtleld side with-a corresponding opening 5, the last mentioned opening being of a greater area than the opening 4, and the socket is provided with a slot 6 entering from its end and which communicates with the opening 5. The slot 6 and the opening 5 thus provide a substantially key hole slot.

The handle 3 is provided adjacent'its end which enters the socket of the tool, with a transverse opening within which is received a sleeve 8 that has its closed ends provided with alining openings. Passing through the openings in this sleeve is a locking olt '7 which has one of its ends enlarged and rounded, as at 10, and provided with a finger hold or head 11 extending from the said enlarged portion 10. The portion of the bolt within the sleeve and adjacent'to the free end of the said bolt is provided with an ofl'set stop member 10', and surrounding the locking bolt and exerting a pressure between the stop member 10' and one of the end walls of the sleeve is a helical spring 9. The bolt is of a size to be snugly received through the slot6 of the key hole opening and through the opening 4 in the socket member 1 arranged diametrically opposite the enlarged rounded opening 5 of the key hole slot, so it will be noted that when the locking pin is retracted or drawn outwardly of the sleeve against the action of the spring 9, the bolt proper may pass through the slot 6 until the enlarged rounded portion 10 of the said bolt is brought to alinement with the rounded opening 5 of the keyhole slot when the pin is released, permitting the rounded portion 10 thereof to engage with the wall of the opening 5 of the key hole slot and the end of the bolt proper to enter the opening 4, thus locking the tool 1 upon the handle.

Having thus described the invention, what I claim is:

The herein described means of connecting a handle to a tool, including in combina tion, a tool having a socket provided upon oneend with an opening and upon its diametrically opposite end with a key hole slot, the roundedopening of the slotv being ofa greater diameter than the first'referred to opening and being in alinement with the said opening, a handle having one of its ends disposed'to enter the socket of the tool,

said handle-having a transverse opening, a

sleeve having closed ends at the opening and the said closed ends provided with alining openings, a bolt member passing through the opening in the sleeve, a stop member portion of the ke hole slot when the bolt 5 is retracted to permit of the end of the same passing through the referred to restricted opening in the socket of the tool.

In testimony whereof I afiix mysignature in presence of two witnesses.
