FIRE TOOL Filed Dec. 19, 1 49 Rose M. Shearer Pauline R. Adams INVENTORS Patented May 6, 1952 TENT OFFICE FIRE TOOL Rose M. Shearer, Crystal City, and Pauline R. Adams; Fort Worth, Tex.

Application December 19, 1949, Serial No. 133,754;

2 Claims. (Cl. 294-2) This invention relates to a hand tool adapted for use in camping and in the home and has for its primary object to provide. a tool which consists of a cap lifter, fuel hook, tongs and a shovel, all supported on one elongated handle.

Another object of this invention is to provide a tool which is relatively light in weight, durable, and easy to manipulate in such a manner that a push or pull on the handle thereof will actuate a plunger having pointed hooks at the end thereof which can be employed for moving fuel, water or coal, for lifting skillet lids, for picking up articles, and for clamping a shovel to the end of the plunger.

Yet another object of this invention is to provide a combination tool comprising opposed S-shaped tongs each having a depending hook at one of its ends, a bar terminally pivoted to the other end of said tongs, an elongated tube having a bifurcated end straddling said bar, means carried by said bifurcated end adapted to engage said tongs and urge them toward a closed position, a rod secured at one end to said bar extending through said tube and having a handle at its other end, and resilient means urging said rod and tongs into engagement with said first-named means.

These, together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the device, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figur 1 is a perspective view of the assembled device or tool;

Figure 2 is a longitudinal sectional view taken substantially on the plane of section line 2-2 of Figure 3;

Figure 3 is a fragmentary side elevational view of the device, parts being broken away to show details of construction; and

Figure 4 is a sectional view taken substantially on the plane of section line 44 of Figure 1.

Specific referenc is now made to the drawings. In the several views in the accompanying drawings and in the following specification reference characters indicate corresponding elements throughout.

Indicated generally at I I] is an elongated tubular member which, like the remainder of the parts of the present tool, is fabricated preferably of steel. At its bottom end, the tubular member is bifurcated, the furcations l2 and [4 thereof being flattened. Secured as at I6 to the ends of the furcations l2 and I4 is a pair of" laterally extending bars l8 andiZB' which are; in turn, secured to each other adjacent their ends by means of rollers 22.

At its upper end, the tubular member it is threaded as at 25 to receive a bushing 26 that is also threaded as at 28 to receive, in turn, a cap 30 that is threaded on one end of a cylinder 32 which receives a closure cap 34 at its other end. A rod or plunger 36 extends through the tubular member and through the cylinder. 32 and is provided at its upper end with a handle portion 38. Received in the cylinder 32 and wound about the rod is a coil spring 40 which is interposed'between the threaded end of the bushing 26 and a stop 42 secured to the rod 38. This spring is so tensioned as to urge the stop 42 toward the closure cap 34 of the cylinder 32.

At its bottom end, the rod 36 is secured as at 44 to a bar 46 which is, in turn, pivoted at its ends as at 4-8 to the upper ends of a pair of opposed S- shaped arms 50 and 52 which carry laterally extending hooks '54 at their free ends. As will be seen clearly from Figure 1, the furcations l2 and M of the tubular member ID and the rods I8 and 20 secured thereto straddle the S-shaped arms. Secured as at 56 to the arms l8 and 20 is a triangularly shaped wedge 58 for a purpose to be later described. A shovel 60 is provided having an end wall 62 provided with spaced S-shaped lugs 64 for slidably and demountably receiving the hooks 54.

In practical operation, it will be seen that the spring 40 urges the handle 38 and rod 36 upwardly or toward the right of the figure so that the rollers 22 of the bars I8 and 20 ride on and engage the outer edges of the s- shaped arms 56 and 52 urging them toward each other into a closed position. By pushing downwardly on the handle 38 against the action of the spring 46, the S- shaped arms 50 and 52 are caused to move outwardly of the bifurcated end of the tubular member ID and out of engagement with the rollers 22, the triangular wedge 58 engaging the inner edges of the arms 50 and 52 at their constricted portions to urge them outwardly. Thus it will be seen that the S-shaped arms and depending hooks 54 can be used for gripping various articles in the form of a pair of tongs, and when it is desired to mount or demount the shovel 60, the shovel need merely be held in place while the handle 38 is pushed and pulled to allow the hooks 54 to engage the S-shaped lugs 64 on the shovel.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A combination tool comprising opposed s-shaped tongs each having a depending hook at one of its ends, a bar terminally pivoted to the other ends of said tongs, an elongated tube having a bifurcated end straddling said bar, means carried by said bifurcated end adapted to engage said tongs and urge them toward a closed position, a rod secured at one end to said bar extending through said tube and having a handle at its other end, and resilient means urging said rod 4 and tongs into engagement with said first-named means, said first-named means including plates secured to said bifurcated end and straddling said tongs and rollers between and adjacent the ends of said plates adapted to engage the outer edges of said tongs and press them together.

2. The combination of claim 1 and a triangular wedge secured between said plates adapted to engage the inner edges ofsaid tongs at their constrictions and urge them apart.
