3 Claims.

This invention relates to combination hand tools, and in particular to a combination tool suitable for use by military personnel, as well as by hunters and others.

An object of this invention is to provide a combination tool which is so constructed that rapid conversion from one type of tool to the other is possible.

A further object of this invention is to provide a novel means of rigidly connecting combination tool elements to a handle therefor. The connecting means is nonetheless simple in construcion.

Still other objects and advantages will become apparent from the following description and the accompanying drawings, in which:

Figure 1 is a plan view of the invention;

Figure 2 is a plan view of the invention showing a segment of the shovel blade in position for use of the tool as an axe;

Figure 3 is a sectional view taken on line 3-3 of Figure 1;

Figure 4 is a sectional view taken on line l4 of Figure 2;

Figure 5 is a sectional View taken on line 55 of Figure 2;

Figure 6 is a plan view of the invention showing the rear thereof;

Figure 7 is a plan view partly in section taken on line 1-4 of Fig. 6;

Figure 8 is a side view with portions broken away for clarity, and with some of the elements shown in relative positions different from those shown in the other views.

Figure 9 is a sectional view taken on line 9-9 of Fig. 6.

Similar reference characters represent similar parts in the several figures.

The present invention has been developed to answer a need for a light multi-purpose tool which embodies a hoe, pick, root cutter and axe which is so constructed as to adequately perform the various functions of such tools. The combination tool herein disclosed is also formed so that it is compact and can be easily carried.

Previously developed combination tools of the type herein disclosed have a common fault in that the means for connecting the tools to a handle therefor fails to provide adequate strength and ri idity, and in addition fails to provide a convenient manner of converting from one type of tool to another.

It will be obvious from the following description that I have devised a tool which has none of the objectionable features of prior similar tools.

The present tool comprises a shovel blade l0 and a handleli. Blade It is provided with the usual camber and includes tapered forward edges I2 and it with parallel side edges l4 and IS. The forward edges may be sharpened to facilitate their entry into the soil.

The blade further comprises a main portion l6 and a movable segment l'l. Main portion [6 has mounted thereon hinge members is and I9 which pivotally and slidably receive shaft 28. Segment Il has mounts-l thereon bosses 2| and 22 which are secured to shaft 29. Shaft 20 extends downwardly and with the elements in the position shown in Figure 1, seats on ledge 23 (see Fig. 7)' which forms a part of pick 24 mounted on handle i i. Shaft 28, it should be noted, extends longitudinally of the blade and acts as a stiffening element thereof.

Main portion l6 has mounted at the rear thereof (see Figures 2 and 6) a reinforcing strip 25, a sharpened cutting element 25 and a supporting element 27. Cutting element or knife 26 parallels edge 28. Segment I i when in the position shown in Figures 1 and 6, abuts against elements 26 and 21, and edge 29 is in alignment with edge 2 of portion It. Segment I? is cut away at 39, 3|, for a reason hereinafter explained.

As seen in Figures 1 and 5, segment H is engaged by locking bar 32, which is affixed to main portion l5, when in the position shown in Figure 1. Segment I1 is also provided with lock bar 33 (Figures 1, 2, 6 and 9). Edge l5 can be triangular in shape, as shown in Figure 3, and can be undercut at 34. Main portion It has fork- like block elements 35 and 36 attached thereto, which are generally rectangular in shape. Members 35 and 36 are pivotally connected to projection 31 by pin 38. Projection 3'! has a groove 39 formed on the upper surface thereof. When the blade is pivoted to the position shown in Figure 8, shaft 20 which extends parallel to the blade is received within groove 39. This results in addi tional strengthening of the blade for use as a pick or hoe.

Pick 2i has forked elements 151 and ti which have attached thereto rectangular block members 42 and 43, respectively. The blocks are pivotally connected to pin 38. Pin 38 may be peened on its ends to form heads which serve to maintain the pin in position. Of course other securing means, such as nuts, may be used. A central projecting member &4 is attached to the pick and supports ledge element 23.

Handle H tapers at its upper end and receives a sleeve or ferrule fill, which may be held in place by rivet 5|. At its upper end the ferrule is provided with threads and is threadingly engaged by collar 52 which supports washer 53. When in the position shown in Figures 1, 2, 6 and 7, the bottom edges of block elements 35, 35, 42 and 43 abut against washer 53. Collar 52 can be threaded upwardly on handle I B so as to securely fix shovel It and pick 2 in the position shown in the last-mentioned figures. Collar 52 can also be moved downwardly so as to permit rotation of elements 35, 36, 42 and 43, and the connected shovel and pick to the position shown in Figure 8. Collar 52 can then be moved upwardly to force washer 53 firmly against the elements at their side edges. Thus the shovel and pick are securely retained, as shown in Figure 8. When in this position the shovel can be used as a hoe. Shaft seats in indentation 39 when in this position. The indentation or groove 39 not only makes it possible to hold the size of elements and 36 to a minimum since shaft 20 will be received in the indentation, but also, as previously pointed out, serves to strengthen the blade when the blade is moved to the position shown in Figure B.

When the collar 52 is rotated and moved downwardly on handle ll sufficiently, shovel Hi can be rotated independently of pick 24 and brought to rest against handle H in a position similar to that of pick 26, as shown in Figure 1. The collar can then be moved upwardly to hold the two main elements In and 24 in a collapsed position for convenience in carrying.

When the collar is moved downwardly blade ill can be pivoted to disengage shaft 20 from ledge 23. When this is done shaft 28 and attached segment ll can be moved downwardly in hinge members l8 and 19 to disengage I! from lock bar 32. Segment I! can then be rotated so as to overlie the solid portion of the blade [Hi]. When in the latter position, the segment and shaft 20 can be moved upwardly until the segment is in the position shown in Figure 2. In this latter position lock bar 33 engages main portion l6 and edge [4 seats in the detent formed by undercut portion 34.

Blade segment I! is cut away as shown at 31, to permit pivotal movement of the segment over the elements 35, 36 and 4U43. The segment is further cut away as shown at 30 to enable the segment to be moved downwardly with respect to the main portion l6, and then pivoted.

After the segment has been thus positioned, with respect to the main portion of blade ill, the blade is rotated back to the position shown in Figure 2, -or to that of Figure 8, and the collar moved upwardly so as to force ledge 23 to engage shaft 20 and maintain the elements 10 and 24 in position (see Figs. 6 and 8). An additional lock bar or bars can be provided on segment I! and main portion [F5 to assist in holding segment IT in any desired position.

With the blade-elements I6 and IT in the position shown in Figure 2, cutting blade 26 can function as a root or general purpose cutter, and edge [5 can function as a machette or axe.

It is obvious from the foregoing description that I have devised a tool of great utility. It is also apparent that the combination tool elements can be conveniently positioned to perform each tool function. In addition, I have disclosed a means of mounting the tool elements which insures adequate strength and durability.

While I have shown and described a preferred form of my invention, it is obvious that variations in details of form may be made without departure from the invention as defined in the appended claims.
