UNITED STATES HARRY M. WOLFE, OF LAKE BURIEN, WASHINGTON.

HAND-POWER DIGGER.

Application filed April 19, 1923. Serial No. 633,292.

and exact specification, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention is a tool having a sliding hammer on its handle that may be operated by hand, a means for guiding the point or edge of the tool, and a means whereby material dug by the tool may be readily raised to the top of a hole in which the tool may be working.

The object of the invention is to provide a tool for digging deep holes of a small diameter through hard ground.

Another object of the invention is to provide a tool having a hinged blade with a sliding hammer that may be operated by hand from the ground above the hole.

And a further object of the invention is to provide a tool having a means for hammering it into the ground with a means for hole.

With these ends in view the invention embodies a tool having a sliding member on its handle, means for raising the sliding member, a seat for the sliding member, and means for raising the tool or digging member.

vention will appear from the following de scription taken in connection with the drawings, wherein Figure 1 is a side view showing the sliding member in section.

Figure 2 is a front elevation showing the sliding member in full.

Figure 3 is a view showing a pointed tool as it may be guided to a certain point in the hole.

Figure 4 is a detail showing the method of attaching a pointed tool to the handle bar.

Figure is a detail showing the design of the bucket that may be attached to the shovel.

Figure 6 is a.- detail showing a conical shaped digger that may be attached to the handle.

'Figure 7 is a shaped digger. 7

In the drawings I have shown my device I I PATENT- omca plan view of the conical as itwould be constructed'whereinnumeral 1 indicates the handle bar, which maybe made of a small straight bar or tube andmay be made of any suitable length and be made in one piece orin sections ma Y which; may be joined together; Atits lower end is-a member 2 which may be a reducing fitting as shown andsin the lower 'end'of this a larger pipe or bar 3V1nay be placed. This .bar may be made in 'di'iierent shapes so that diiferent tools maybe attached to the member 2 by it, and it may be'screwed' into the member 2 so that 'itmayreadily be interchanged with another similar bar having a' different tool on it. I

Above the member 2 is a disk or' washer 4" that may have a hub 5 on it so thatit may. be held to the bar 1 by the set screw'fi. Thismember will form a seat for a sliding member 7 which may be a straight piece of pipe. of a somewhat. larger diameter than the rod 1 and may have a hole 8 in its upper end which a cord 9 may be attachedto' it through a bolt 10. The cord 9 may be a piece of rope or wire cable; or a chainmay-be used if desired. A flange 11 may be placed on the lower end of the member 7 as shown in Figure 1 which will broaden the lower end and provide a greater wear-J in its side members. The cord 9 may pass over one of these pulleys and another cord 16 may pass over the other pulley and'down ward to the edge of one otthe tools as. shown in Figures 1 and 6. The shovel shown in Figure 1 may have. a blade 17 which may be of any desired shape and "this; may have bars'18 attachedto 'it by which it may beheld by a pin 19 to the bar 3, and may also have a pocket or bucket. 20 extending a little more than midway"down-- ward on its front side. The pocket 20 may be of any suitable size or shapeand may have an indentation21 in its for-ward edge as shown in Figure 5 which will fit around the bar 1 when the shovel is in the upper position or in the position oflifting material out of the hole as shown in dotted lines in Figure 1. The plate forming the pocket 20 may be attached t'o'the -b1'ade17 by rlvet- 13 in its upperside and pulleys l4 and 15 Other features and advantages of the in ing it to the blade by rivets 22 as shown in Figureb or by attaching it to it in any de: sired manner or bymaking itintegral therewith. A spring 23 may be attached to the rear of the blade 17 at the point 24 and also to the bolt which will perform two functions. First it will hold the shovel slightly backward as it is lowered into the hole, and then it will quicken the downward move- 10 ment of the sleeve 7; a lug 25 maybe placed on the back 02E the bar ;3 which will engage the blade and limit its backward movement.

its point r-u k 9Wnn ig re &-

be made of bar26 which may have itslower end pointed as shown ormade in any 4?; the bar or point may readily be inter-.-

desired shape and its upper end held in a piece of pipe or sleeve 27 by a bolt 28. This fi'iure 1 may be attached to it as shown in Figure 3. In Figure 3 I have shown an extension from the cross 12 which may be a strap 30 as shown, or it is understood that this may be made of apiece of chain, rope,

0': or a bar of any desired type or length, and

1 The conical shaped ure 6lmay have ears 31 at its vertexbetweenv it willbe seen that by passing the cord 16 through it it will be possible to guide the point 26 toward the "side. of hole or to.

any object in the hole. v

digger shown in Figwhich a bar 32 which may be similar to the bar 3 with its lower end curved as shown may be pivot-ally held on la pin 33 and in one side of the conical shaped member there may be an indentation 34 to fit around the bar when the member is in the-upper or dotted position. open end of theiconical shaped member is a bail 85 to which a cord similar to the cord 16 may be attached so that the member may be guided from one side ofthe hole to the other or raised in a manner similar to that in which the shovel is raised as hereinbefore described.

It will be understood that changes may be made in the construction without departing from the spirit of the invention. ()ne of which changes may be in the shape or size of either of the digging implements, another may be in the method of attaching either of them to the handle and still another may be in the design of the handle or of the sliding member thereon.

The construction will be readily understood from the foregoing ClGSCllptlOl]. To use the devlce the arrangement shown in Figure 1 may be lowered into a hole and it will be seen that by pulling upward on the cordlGor by letting it downward the point In the of the blade 17 may be moved backward or forward so that the cutting edge of the blade may readily be placed in any desired position. hen this is in place the sleeve 7 may be constantly raised and let fall which will hammer the blade into the dirt and as it is hammered downward the cutting edge will move outward either from the curve of the blade or from the tension being increased on the cord 16, and as enough of the dirt has been loosened to fill the pocket 20 the bucketmay be raised by pulling up on the o 16' unt i .i he i' iQ hown in dotted lines and then it may be raised out of the hole, bythe rod 1 and the cord 16.'

This action would be the same for theconical shaped member shown in Figure '6 encept that the edge of the blade s'hown n Figure 1 would have a greater digging power than the sideoi the cone so that the shovel should be used for hard ground and the cone or a member-of a similar shape used for. soft ground or for holes in which the point 26 has been working. The point 26 may be used to loosen the'hard dirt or gravel. or to break large rocks or other obstacles and by adjusting the

cords

9 and 16 it will be seen that the point 25 may be directed to any ,,desired point.
