To all whom-it mag concern.-
Be it known that we, ROBERT JAMES RUD- ALL, patternmaker, residing at. 31 Cambrian Street, Llanelly, Carmarthenshire, Wales, and THOMAS BROWN, fitter, residing at 3 Glanmoor Terrace, Llanelly, aforesaid,- and JOHN HUGHES WiLLrAMs, bootm'akenriasiding at Liverpool House, Bynes, near Lla- Iielly aforesaid, all subjects of the King of Great Britain, haveinvented a Tool-Handle Fastening, of which the following is a specification. 1
This invention relates to an "improved method of and means for securing handles or shafts to the headof picks, hammers, and the like. v
According to this invention the handle or shaft (hereinafter referred to as the handle) is provided with an enlarged head end or formed larger at one end, and is adapted to fit in a stout metal socket having the bore or interior thereof tapered orshoiildered or otherwise formed larger at one end than at the other end; and the head end of the'hanthe is fitted in this socket so as to become wedged therein and is advantageously made to fit accurately in this socket; and the head of the pickaxe or hammer or the like isthen placed across the larger end. of the socket with the handle wedged therein and is-secured thereto by a clip of U-shape or equivalent which embraces the head and fits ina recess therein to receive same, while the arms of the U-shaped clip extends downeach side of the head end of the handle inside the socket e. between the exterior ofcthe en'- larged head end of the handle and the interior wall of the socket) and are securely the like thereby firmly secured to the handle.
Furthermore this invention comprises other features and details all of which-will be hereinafter fully described with reference to the accompanying drawings and finally pointed out in the claims.
In the accompanying drawings we have illustrated the present invention as carried into practice for securing the head of a pick to the handle therefor.
Fig. 1 is a side view in elevation of a pickaxe-such as used in coal mines-having the head secured to the "handle with the present invention. Fi 2 is a perspective view of the socket alone. i
Fig. 3 is a perspective View of the U- shaped clip alone.
Fig. 4 is'a cross sectional view onthe line in accordance a -4. Fi .i. Fig. 5- is a local vertical sectional 'view on a somewhat enlarged scaleon the line A is the handle to which the head of the pick is, secured according to this invention,
such handle being provided with an enlarged tapering head end A Bis the stout metal socket the interior bore ofwhich is tapered correspondingly, to the tapered enlarged end A of the handle. C is the U-shaped clip, the spring arms C of which pass down inside the socket B and are eachzprovided with an enlarged endC adaptedto engage in the recess B formed oneach side of the lowerend of the socket B. These recessesB are formed opposite to one another in the oppositeside faces of the socket B; while at the top end of the socket B same is slotted Vertically at B to permit the underside of the head D of the pick to fit insaid slot so that said under part of said head is embraced or lies between the front and back topside edges B of the socket B.
The outeredge of the head D of the pick as shown is providedwith a centrally located recessD? for the bent portion of the U-shapedclip O to seat or fit in said recess and thus lock and hold the head; end against endwise displacement of said head- The underside edge of said pick is providedflwith two separate slots or recesses I) (see Fig. 6) adapted to engage and fit down over the top edge of the socket B (when slotted at B as shown in Fig. 6. The interior wall. of the socket B is provided with oppositely disposed vertical grooves B Fig. 2 and the enlarged head end A of the handle is provided with correspending grooves to permit the arms C of the clip (3 to be passed down inside the socket B between the interior thereof and. the exterior of the head end A of the handle A.
The parts are fitted together as follows The smaller end A of the handle A is passed into the larger end of the socket B and the handle A passed through said socket until the larger end A becomes wedged in the interior of said socket as shown in Fig. 6.
The head D of the pick is thencentrally placed transversely across the larger end of the: socket B with handle A therein, as shown in Figs. 1 and 6 and the arms C of the clip C are then passed down each side of the head D and threaded down the aforesaid grooves inside of the socket B on each side of the head A of the handle A (i. e. be tween the head A and the inside wall of the socket B) until the enlarged head end C of each arm C sprin s outwardly into and engages in the slots whereupon the whole of the parts are securely attachedtogether and thus the head D of the pick is firmly secured to the handle A. I
If it he desired, incident to probable shrinkage of the handle A, the socket B may be secured to the handle by a rivet, screw, nail or other suitable device, which may pass in an edgewise direction through the socket and'handle to insure the retention of the socket in place.
It will be obvious that various modifications could be made without departing from the scope of this invention; for example the socket B could be made without the slots B therein in which case the arms G of the spring clips G would then be made longer and the enlarged head ends C engage the bottom edge of the socket B. If desired the head end of the handle could be fastened by any suitable means to the socket instead of or in addition to being a tight fit but always in suchwise that the head end of said handle cannot be drawn through the said socket.
What we claim is: I
1. The herein described means for securing the head of a pick, hammer, or the like to the handle therefor; comprising a handle having the head end thereof tapered and said tapered portion being larger in crosssectional area than the remaining part of said handle, a stout metal socket having the bore thereof tapered as a counterpart to said tapered head end of the handle, a tool head having slots on the underside thereof adapted to engage with and it down over the top edge of the aforesaid socket at opposite sides thereof, said. head of the tool having a recess in the top edge thereof, a sprlng clip of inverted U-shape adapted to embrace said head and fit down in said recess therein and the arms ofsaid clip adapted to pass down the opposite sides of the head of the handle inside said socket, said socket hav ingoppositely disposed grooves extending lengthwise thereof to receive the arms of said clip, and means on the outside of the socket having the bore or interior thereoftapered as a counterpart to said tapered head end of the handle, said metal socket having oppositely disposed slots in the top edge of the larger end thereof located in such wise as to permit the underside edge of the head of the tool to lit in said oppositely disposed slots so that the top end of the socket will embrace the side faces of said head when all the component parts are assembled and fixed in position, a tool head having; slots on the underside thereof adapted to engage with and fit down over the top edge of the aforesaid socket at opposite sides thereof, said tool head having a recess on the top edge thereof, a spring clip of inverted U-shape adapted to embrace said head and fit down in said recess therein and the arms of said clip adapted to pass down the opposite sides of the head of the handle inside said socket, said socket having oppositely disposed grooves extending lengthwise. thereof to receive the arms of said'clip, and n'icans on the outside of the end of each of the arms of said clip adapted to pass down said grooves inside said pocket and to en gage the lower end of said socket for locking and holding all the aforesaid components in position.
