G. M. GEST HAMMER SHOVELA Filed May 29. 1923 Patented Unt. ld, i924.
GU'ION M. GEST, OF` NORO''ON, CONNECTICUT.
HAMMER SHOVEL.
i .Applicationl filed May 29,
To all whom t ma@ concern.'
Be it known that I, GUioN M. Gnsr, a. citizen of the United States, and a resident of Noroton, county of Fairfield, State oi' Connecticut, have invented certain new and useful Improvements in Hammer Shovels, ot which the following is a specification.
This invention relates to a novel form of portable hand-manipulated power driven shovel.
The object of the invention is to provide portable means for supporting and lifting such a shovel, so as to relieve the operator of the burden of lifting such a heavy tool, leaving to him only the work of guiding, controlling and turning the shovel.
To this end, the invention comprises the combination with the shovel and its driving hammer, of a portable carriage and a balancing supporting arm mounted on the carriage that will flexibly support the shovel and its connected hammer1 and which may also be made use of as a means of lifting the shovel and conveying the same to the place of dumping.
A preferred embodiment of my invention is illustrated in the accompanying drawings, in which:
Figure 1 represents a side view in partial section of the hammer shovel; and
Figure Qrepresents an end view of the hammer shovel.
In the `torm shown, the shovel 1 is made scoop-shaped and in this form, is well adapted for the digging or" narrow trenches. An arm or handle bar 2 is securely attached to the shovel at, for instance, 3, where the end of the rod ts into the bottom of the scoop and at 4 where the rod passes through the back of the scoop.
At 5 is shown a pneumatic hammer meinber of usual construction, having hammer piston 6 in cylinder 7 supplied with compressed air by hose 8.
A T-handle 9 at the rear of the hammer member enables the operator to easily control the application of the shovel to the work while the work of driving the shovel is performed by the hammer blow delivered to the end of the rod 2 by the reciprocating hammer piston 6. As the associated parts thus described are too unwieldy to be lifted by the operator, I combine therewith a suspending and lifting means in the form of achain 10 coupled by a link 11 to the arm 2 of the shovel, and hung from any form of suitable 1923. Serial No. 642,229.
supporting arm 12. The point where the supporting chain is coupled to the armis selected so that the weight of the shovel and its load is, to a certain extent, balanced by the weight of the hammer. Any lack `of balance is taken care of by the operator lifting up o-r bearing down upon the handle 9. The supporting arm may be, for example, as shown, the lever of a balancing carriage consisting of wheels 13 and axle 14. In such an exempliication, a helper-by put ting his weight on the long arm 111 of the lever 12can easily lift the combination shovel and hammer with its load, he being assisted vtherein by the hammer operator, who can easily depress the hammer end.4 by putting his weight on the handle 9. The two operators can then swing the. shovel to one side where it can be emptied by the hammer operator turning the handle 9, the swivel link 11 easily permitting such dumping.
The combination thus described provides a cheap, portable and eiiicient mechanism for the digging of trenches or shoveling up loose or fairly hard material.
1. A portable hammer shovel adapted to be hand manipulated, comprising a portable support, a -flexible suspension means depending from said support, a shovel bar hung midway from said flexible support, a shovel mounted on one end oi said bar, a power driving means mounted on the other end oi' said bar whereby the weight of the shovel is balanced by the weight of the power driving means.
2. A portable hammer shovel adapted to be hand manipulated, comprising a portable support, a flexible suspension means depending from said support,` a shovel bar hung midway from said flexible support, a shovelv mounted on one end of said bar, a power driving means mounted. on the other end of said bar whereby the weight of the shovel is balanced by the weight of the power driving means, and a controlling handle at the end having the power driving means for guiding and raising the shovel.
3. A portable hammer shovel adapted to be hand manipulated, comprising a carriage, a supporting and guiding arm balanced on the carriage, said arm having a manipulating handle on one side of the carriage and a flexible supporting means on the other side, av power driven shovel comprising 3,? I l v 1,511,880
