CHARLES S. ANDERSON, OF PORT ANGELCES, WASHINGTON, ASSIGNOR OF ONE-HALF TO THEODORE F. BIXON, OF BEAVER, WASHINGTON.

COMBINATION TOOL.

Application filed October 2, 1928. Serial No. 666,088.

Toall whom it may concern:

Be it known that I, CHARLES S. ANDERSON, a citizen of the United States, and residing at Port Angeles, in the county of Clallam and State of Washington, have invented certain new and useful Improvements in Combination Tools, of which the following is a specification.

My invention relates to improvements in convertible or combination tools and it is within the province generally of the subject matter of this application to provide a combination implement especially adapted for foresters use in fighting fires and for campers and automobilists in'the manifold uses they may have in camp or emergency for a tool of the type hereinafter described.

One of the principal objects of the invention is to provide a device of the class men-- 20. tioned of simple, light and economical construction which can be folded into small compass to occupy but little space in a camping outfit or tool-box and which may be readily and quickly converted into a serviceable shovel and cutting tool, or into a hoelike implement.-- i

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention. 7 In the accompanying drawings Figure 1 is a plan view of a tool made in accordance with my invention, shown in operative condition as a shovel; I

Fig. 2 is a view in side elevation of the same, shown in operative'condition as a hoe.

Fig. 3 is a view in side elevation of the handle, detached.

Fig. 4 is a fragmentary view of the implement embodying my invention in longitudinal section and as in process of being converted from one of its operative positions to another.

Fig. 5 is a view in side elevation of the implement in folded position.

Referring to said views, the reference numeral 1 designates a hollow tapered socket containing the tapered chamber 2 to, receive 55 the handle 3, to be more particularly described. Said socket is made relatively heavy at its outer, smaller end and is formed with .an axially arranged bore 5 therethrough which also extends through a receiver 6 welded or otherwise rigidly secured to said smaller end of the socket through tongues 7. Said receiver is substantially a channel-shaped member having a rectangular groove 8 and lateral walls 10 and 11 perpendicular to its base 12. --One of the walls 10 of said receiver is of less height than its opposite wall I I a A blade 15 consists of a sheet of steel formed to a suitable and convenient shape to serve on occasion as a shovel blade, or the like, and to that end is preferably formed somewhat concavo-convex and pointed at its outer end, as at 16. The inner end of the blade is straight and atright angles to the handle 3 and is formedwith a square rolled shoulder 17 effected by bending the metal from which the blade is made upon itself into a hollow rectangular form of exterior dimensions proportioned-to fit snugly within the receiver-groove 8. 18 is a metal block having square ends 20 rigidly secured, as by welding, medially within said hollow shoulder, and having a middle cylindrical portion 21 constituting a wrist-pin which is engaged by'the apertured end 22 of a tension rod 23 which extends through the bore 5 into the chamber 2 whereat it is screwthreaded, as indicated at 25. A nut 26 may be screwed down on said rod 23 to prevent the rod from being accidentally removed from said bore, and the blade and socket thus separated. The'shoulder 17 is'cut away at its middle toexpose the wrist-pin 21 and admit of the pivotal movement of the end 22 thereon. The handle 3 is provided with aferrule 27 at one end tapered to correspond with the socket chamber 2 and is formed with an internally screw-threaded aperture 28 in its axis which when the ferrule is thrust into the socket will register with the threaded end 25 of said tension rod and form a not into which said rod end enters and tension may be exerted thereupon.

To secure the blade in either of the ope ative positions illustrated in Figs. 1 and 2, the blade being turned in the desired manner relative to the handle and the shoulder 17 being entered into the receiver-groove 8 the end 25 of the tensionrod will engage the aperture 28 of the handle ferrule and upon turning the handle said aperture will serve as a nut to exert tension on said rod and seat the shoulder firmly and. positively in the groove 8 and cause the blade to be rigidly. secured to the handle. Vhen thus securely joined to the handle the blade can be used for useful work and will stand hard usage as the parts are strong and of sufiicient stability where the strains are felt. In either. of said two positions'of theblade which respectively represent its positions as shovel and hoe it is equally secure and is retained in the same manner as the shoulder 1'? is square incross section and in either position will be equally welll-fit-ting and supported by said: receiver.

When changing from one form of tool to another the handle is turned to unscrew thenut-a-perture 28 from the end 25' until the latter isentirely relieved therefrom, as indicated in Fig. 4, except that in said view the blade is turned ninety degrees from its normal position relative to the socket; With the rod 21 relieved from connection with the handle and the shoulder 17 removed from the receiver 7 the blade can then be swungon the apertured end 22 througlr an arc of ninety degrees to change the tool from a shovel togafi hoe or viceversa and will thus be secured in the n1anner described.

When the tool is to be stored away the tension rod 23 isreleased from the screwthrea'd's 25 and the blade can be folded over upon the socket 1' as indicated in Fig. 5, after the shoulder is removed from the receiver. Th'e'handle may or may'not be removed from the socket as provision is made to retain the handle in the socket so that it will not he accidentally displaced therefrom when the rod23 is disconnected. The socket is formed with aslot in its side wall inwhich a flat-spring 31 is secured at one end by a screw 32. At the opposite end the spring is formed with 2 lug 33 directed inwardly and? extending into the socket chamber'2.' The ferrule 27 of the handle is formed with an annular groove 35 into which the lug 33 may snap when the ferrule is pushed into the socket andwhich' will secure the handle in the socket against withdrawal until the end 36 of the spring is lifted and the lug removed from the groove 35. 37 indicates a cutting edge providedon one of the lateral edges of the blade 15 which Will afford a useful device for cutting brush or for other emergency work.

As will be evident the invention is simple in its construction, light and strong in its design, and a useful and practical tool for the usesforwhich it is intended. It is primarily intended as a tool for firewardens and forest rangers in fighting fires where water is not obtainable and the fire may be extinguished by smotheringrwith dirt, as isnow customary, although shovels of ordinary size are not usually available in: the remote camps of the fire-wardens; The handles 3 of the shovel illustrated herein may be of any suitable length but preferably it is relatively short so that it may be contained in a convenient sized pack.

H a-ving described my invention,- what I claim, is z- 1. A convertible tool, consistingv in a socket, ahandle in said socket formed with a: screw-threaded aperture',fia channeled re ceiver rigidly secured on said socket, a. blade having a square shoulder on its upper edge adapted to seat in said receiver in two relatively angular positions ninety degrees apart,- and athreaded rod pivotally connected to said shoulder and engageable by said handle to seat said blade-shoulder in said receiver under tension in either of its twosaid positions.

2.: A convertible tool,-v consisting ina socket having a tapered handle-receiving chamber formedwith an axially aligned aperture therein, a-receiver rigidly secured to the end v of the socket and formed with a channel. atright angles to the axis of said socket, a blade, a rectangular. shoulder formed: integral along the upper edge of said blade and adapted to bereceived within the receiver channel,- a: tensionv secured at one end to said shoulder and extending through said socket aperture,- the opposite end of said rod being provided with screwthreads, and a handle rotatable in: said socket and formed with. a. screw-threaded aperture to receive the end of saidrod and exert tension thereonto seat the blade shoulder firmly in said; receiver.
