CHARLES E. HUM'MELGARD, OF JERSEY CITY, NEW JERSEY.

COMBINATION SHOVEL.

Application filed March 9, 1923. Serial No. 628,837.

concern: I

Be it known that CHARLES E. HUMMEL' GARD, a citizen of the United States, residin at J erse City, in the county of Hudson and State New Jersey, have invented certain new and useful Improvements in Combination Shovels, of which the following is a specification.

This invention relates to shovels, and the main object is to provide a shovel havin the spoon thereof adjustable to any desire angle. By varying the angle of the spoon relative to the handle, it may be used suceessively as a hoe, scraper, or shovel.

Another object is to provide a shovel having an angularly adjustable spoon. and an associated means whereby the spoon of said shovel may be quickly secured permanently in the desired position by manipulation of a nut.

These andother objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referrin briefly to the drawing, Figure 1 is a front e evational view of the shovel.

Figure 2 is a side elevational view of the same, the broken lines illustrating the positions which may be assumed.

Figure 3 is an enlarged sectional eleva tion and the lower end of the handle, showing the securing means in locked position.

Figure 4 is a similar view showing said means released to permit the spoon to be rotated.

Figure 5 is a fragmentary elevational view of the upper end of the spoon member.

Referring to the drawing in detail, the

numeral 10. indicates a relatively stout handle which may be made of wood or similar material. The lower end of said handle is tapered and fits into a socket member 11 having a pair of spaced apart ears 12 and 13 projecting from its lower end, a bolt 14 bemg adapted to pass thru said ears. The space between the ears is adapted to receive a substantially semi-circular tongue 15. A neck 16 extends downwardly from said tongue, and a flat blade 17 projects integraly from said neck and forms the spoon end of the shovel. Said blade is widest where it joins the neck, and tapers conver ently towardsits lower end to a sharpenef edge 18. Said bolt 14 passes thru the hole 19 in the tongue and provides the supporting view of the upper end of the spoonpivot for the blade. A wing nut 20 engages the threaded end of the bolt, the opposite end of the latter having a semi-spherical head 21 which normally rests on the face 22 of the ear 12.

A plurality of radially disposed holes 23 are formed in one face of the tongue concentrically about the large hole 19. Said holes face and contact with the inner surface of the tongue 12. A solid collar 24-, from which a short stem 25 projects, is slide bolt mounted within an annular recess 26. A similar stem 27 projects from the opposite side of the collar 24 and slides in an opening formed in the tongue 12. The annular chamber 26 in the tongue has a relatively small conical-edged washer 28 securely bezelled on a shoulder at the open end of the chamber. A coil spring 29 is wound about the stem 25 and contacts with the inner surface of the washer, normally urging the collar 24 outwardly. The lower stem 25 is adapted to be inserted into any of the holes 23, lyvhen one of the latter is aligned therewit I The device may be conveniently used as a shovel when the spoon is tilted to an angle as indicated by the broken lines in. Figure 2, or, when at right angles to the handle, as a hoe. As shown in full lines in Figure 2, it is adaptable as a sore r for cleaning and removing snow or the ike from pavements.

In order to secure the spoon 17 in any of the positions shown, the wing nut is unscrewed until the head end of the bolt 14 is lifted from the surface 22. The spring 29 will urge the collar 24 outwardly, pul mg the. lower stem out of the corresponding hole 23 which is aligned therewith. The s oon is then rotated until the desired ange is reached. The nut may be then tightened down on the bolt. In tightening the wing nut, the head will engage the upper plunger stem 27, thereby urging the lower stem into its respective hole 23. I It is obvious that with-this type of tool it is unnecessary to detach any part when changing the posltion of the spoon relative to the handle.

I claim:-

1. A device of the class described comprisin a socket member having a pair of space apart ears thereon, a handle on said socket, a shovel spoon, a tongue member rigid on said spoon having a plurality of small holes on one face, a bolt passing thru said ears and tongue, a wing nut engaging said bolt, a plunger slidable in one of said ears, one end 0 said plunger extending above the surface of the ear and beneath the bolt head, the latter being adapted to ur the end of said plunger stem into ahole 1n the tongue when tightened down on said ears, said plungerbeing adapted to lock the spoon inplace by engaging a hole in said tongue, and means for lifting said plunger out of engagement with the tongue.

2. A device of the class described comprising a socket member, spaced-apart ears thereon, a spoon, a tongue on said spoon havin a plurality of holes radiatin abouta centre opening, a bolt passing tfiru said ears and central opening, a chamber in one of said ears ali ed with the radiating holes, said chamber g opened at one end, a washer beveled into said open end, a plunger, a collar on the plun r, said collar being slidable in the chem r, a spring in the chamber normally urging said plunger to proect outwardly from the ear, a head on sai bolt, said head being adapted to depress the stem causing the op osite end of said stem to engage in any 0 the holes to lock the spoon 1n position.

In testimony whereof I affix my signature.

CHARLES E. HUMMELGARD.
