TOOL-HANDLE.

To all whom it may concern.' y l.

Be it known that I, HUGO J. KALLINIGH, a citizen of the United States, residing at Southington, iii the county of Hartford and State of Connecticut, have invented a new and useful Improvement in Tool-Handles, of which the following is a specification.

This invention relates to a handle which is designed to receive various tool blades, such as screw drivers, wrenches, wood chislls, cylinder scrapers, knives, saws and the The object of the invention is to produce a very simple, cheap and strong handle which is so constructed that various styles of tool blades made of flat tool steel can bequickly applied and firmly secured and yet can be easily removed when it is desired to substitute a different blade, whereby a complete set of tools may be provided which will occupy such small space as to make the outfit particularly useful for the kits of automobilists, mechanics and artisans who carry their tools from place to place and conseuuently for convenience desire a number of tools packed in as small and light a parcel as possible.

To attain the ends sought a handle is provided which will receive and securely hold the various tools which can be made from thin flat tool steel. This handle is desirably made to insure strength and lightness from a piece of steel which is blanked to the necessary shape and folded to the `required form about a cheap, lightyet rigid core, leaving` a socket in one end for the reception of Hat tool shanks. Simple means are provided whereby the tool shanks may be quickly thrust into the socket in the `handle and easilv locked so that they cannot be removed until the lock is released and then the tool shanks can be readily withdrawn.

Figure 1 of the accompanying drawings shows a side view of a handle which embodies this invention, holding a screw driver y blade. Fig. 2 shows an edge view of the handle with the screw driver. Fig. 3 shows a cross section of the handle on the plane indicated by the dotted line 3-3 on Fig. 1. Fig. 4l shows a cylinder scraper that may be applied to the` handle. Fig. 5 shows a wood chisel adapted to be used with the i handle. Fig. 6 shows a wrench jaw that 5 `may be used with the handle. These tools Specification of Letters lPateiit.

are merely illustrative of` a large number which may have been provided for use with this handle.

`The handle 1 may have any desired out-` line, preferably wide `enough to insure a `goed and firm grasp, and so thin that it will occupy but `little space in a tool kit; In making this handle, a sheet of steel or other suitable metal blanked to the necessary shape is folded about a cast iron skeleton frame Q. The edges of the folded plate may be joined in any suitable manner as by brazing, or the parts may be held together by rivets 3 or other means.

In the end of the handle is a thin rectangular socket for receiving the flat shank 4.- of the `tool blade. The end of the interior frame is utilized to form a stop for the tool shank `when thrust into the socket. A small opening is made through one side of the handle into the socket and in this opening is placed a steel ball 5. This opening is made in such manner that a portion of the surface of the ball will project into the socket and. the ball. is retained therein by a spring finger 6 that is provided with a pocket 7 which fits over the ball and is held to the handle by a screw 8.

The shank of each of the tool blades has a. perforation 9. Then the shank is thrust into the socket in the handle the ball is crowded out, the spring finger yielding to allow this, until the end of the shank abuts against the end of the interior frame, then the spring forces the ball into the perforation in the shank and thus holds the blade in place.

The springr finger beyond the ball pocket has a tongue 10. Adiacent to this tongue and movable over it is a locking disk 11. This disk is held to the face of the handle by a screw 12 and it has one corner 13 bent outward so that when that end is turned around it will readily nass over the tongue and hold the spring finger down. If the spring finger is held in this manner the ball cannot yield and thus it locks the blade shank in place in the socket. The disk desirably has a part 1.4.A blanked out of it by means of which it may be turned for locking i or releasing the ball retaining spring finger.

llVhen the finger is not held bv the locking j disk a tool shank can be quickly thrust into or pulled out of the socket, as the ball readily is locked by the disk, the ball cannot yield so that a tool shank can neither' be thrust into nor pulled out of the socket.

The locking mechanism illustrated and particularly described is simple to make and convenient to operate, and consequently is the preferred construction, but the invention is not limited to the specifically described details of these parts.

The invention claimed is:

l. A tool handle having a tool holding socket in one end, means projecting into the socket for locking a tool shank therein, yielding means normally thrusting said locking means into the socket, and means adapted to engage said yielding means and Cpleso this patent may be obtained for ve cents each, by addressing the Commissioner of Ta tems,

Washington, D. C.
