DETACHABLE TOOL-HANDLE.

Specification of Letters Patent.

' Patented Oct. 24, 1905.

Application filed January 20, 1905. Serial No. 242,017.

To all whom, it ntay concern.-

Be it known that we, FRANK W. MoOUNE and JAooB M. TEACH, citizens of the United States, residing at Stuart, in the counties of Adair and Guthrie and State of Iowa, have invented certain new and useful Improvements in Detachable Tool-Handles, of which the following is a specification.

The object of our invention is to provide simple, durable, and inexpensive means for connecting handles to tools.

Our invention consists in the construction, arrangement, and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which Figure 1 shows a vertical central sectional view of a device embodying our invention.

Fig. 2 shows a detail view of the bolt, and

Fig. 3 shows a plan view of the sockethead.

Referring to the accompanying drawings, the numeral is used to indicate the body portion of the socket-head, substantially oval in cross-section and formed with a fiat top 11, designed to engage and rest upon the under surface of the tool. Formed on the top surface 11 are two upwardly-projecting lugs, the upper surfaces of whichare tapered, and the side edges are tapered toward the center of the tool. These lugs are indicated by the numeral 12. In the central portion of the socket-head 10 is a smooth round opening 13, extending downwardly into the socket-head a short distance. Below the lower end of the opening 13 is a slot 14, which communicates with a large recess at the bottom of the socket designed to receive the upper end of a tool-handle 15. We connect the wooden handle with the socket by first insertingit therein and then driving a wedge 16 downwardly through the opening 13 and the slot 1 1, so that the wedge will spread the upper end of the handle and firmly retain it in the socket.

The tool proper, which in the accompanying drawings is shown to be a miners pick,

is formed on its under surface with notches designed to receive the lugs 12. It is also formed with a central opening designed to receive the bolt 17. This bolt 17 is screwthreaded at its upper end, and its lower end is designed to pass into the opening 13 of the socket. We have provided for detachably connecting the bolt with the socket by forming a transverse opening 18 in the socket, a portion of which opening intersects the opening 13, and in the bolt 17 we have formed a notch 19. By this arrangement of parts and assuming the bolt 17 to be in position in the opening 13 we then pass a round pin 20 into the opening 18 and through the notch 19. In this way the bolt is firmly held against both rotary and longitudinal movement in the socket 10, and yet it may be very readily and easily detached by simply sliding out the pin 20. A nut 21 is screwed to the upper end of the bolt 17 and rests upon the top of the tool. In use the pin 20 is made of such size that it will fit into the opening provided for it, and yet the said pin is prevented from accidental displacement by having the nut 21 screwed tightly to the bolt, thus drawing upwardly on the bolt, and thereby firmly clamping the pin 20 in position.

In practical use and assuming the parts to be assembled, as shown in Fig. 1, the tool is firmly held to the socket by means of the bolt 17, and rotary movement of the head relative to the socket is prevented by the lugs 12 entering notches in the under surface of the tool. If during use the tool should become loosened on the socket, the operator may quickly and easily tighten it by adjusting the nut 21. Assuming that it is desired to remove the tool and substitute a new one, the operator simply loosens the nut 21 without detaching it. Then he pushes the pin 20 until it disengages the bolt, and the bolt and the tool may both be removed. A new tool is then substituted, the pin 20 reinserted,and the nut 21 again tightened. Allof this may bedoneveryquickly and easily, as it is only necessary to turn the nut 21 about one complete revolution. In this way the operator will not mar the thread of the bolt 17 during the process of attaching ordetaching tools, because the nut need not be wholly removed.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States therefor, is

l. The combination of a handle socket formed with a smooth opening extending longitudinally thereof and also formed with an opening extending transversely through it and partially intersecting the longitudinal opening, a tool formed with an opening, a bolt passed through the opening in the tool and into the longitudinal opening of the socket,

said bolt having a notch at its lower end and screw-threaded at its upper end, a pin designed to pass through the transverse opening of the socket and enter the notch in the bolt, and a nut seated on the top of the bolt to engage the top of the tool.

2. The combination of a socket formed with a longitudinal smooth opening at its top, a slot at the bottom of the opening and a handle-recess below the slot communicating therewith, said socket also formed with a transverse opening partially intersecting the longitudinal opening, lugs formed on the top of the socket, a tool formed with an opening, a bolt passed through the opening in the tool and into the longitudinal opening of the socket, said bolt formed with a notch near its lower end and screw-threaded at its upper end, said tool also formed with notches to receive the lugs on the socket, a pin inserted in the transverse opening of the socket and passed through the notch in the bolt, and a nut screwed to the top of the bolt and engaging the top of the tool-head.
