ANDREA GUIDUCCI, OF PECKVILLE, PENNSYLVANIA,
JACK-HAMMER ansa'.`
Application led February 25, 1927.
My present invention, in its broad aspect, has reference to improvements in supports; and more particularly it is my purpose to provide a support for jack hammers, and for power boring and drilling tools, and to this end I have provided unique and novel means in conjunction with the support for powerfully urging the tool bearing end of the support toward the work, or in the direction in which the tool is to be fed, thereby eliminating the arduous labor heretofore characterizing the forcing of a power hammer, drill or the like upon or into the work by the operator.
Other equally important objects of my invention may be briefly defined as follows; first, I have attained through the instrumentality of a weight and a lateral arm on the support on which the weight is carried, 0 an off-center distribution of a load on the support toward the work, thereby to powerfully urge the tool bearing end of the support toward the work to feed the tool into the work; second, I have provided means for adjusting the height of the support, and;
third, a simple and novel foot for the support enables me to pinch or pack the support toward the work as the tool feeds into the work under the influence of the weight.
In the drawing wherein, I have shown the principal embodiment of my invention':-
Figure 1 is an assembly view of my support, a tool being shown conventionally thereon, and illustrating its application to the work,
Figure 2 is a sectional view of my support, and
Figure. 3 is a detail view of the foot of my support.
In the drawings, like characters of reference are used throughout the several views to designate like or similar parts.
The numeral (1) designates a base which may be a iioor or the like, and (2) a cement wall or the like in which it is desired to bore or drill an opening by means of a power or jack-hammer, or drill, or the like which is conventionally shown at (3).
The jack, or power hammer, or the like (3) is supported in position by an adjustable and sectional standard (4). The standard (4) has a hollow or tubular body (5), the ends ot which are open to receive upper and lower rods, respectively designated (6) and (7). The free end ot the Serial No. 170,925.
upper rod is formed with a bracket or saddle (8) which carries the tool (3), and the remaining end of the rod is screw threaded as. at (9) to a point near the middle thereof 60 to receive thereon a nut (10) whereby the rod is :ted into and out ot the tubular body (5). The nut has a pivoted operating handle (11) therein so that it may be readily manipulated. A stop screw (12) moving in a slot (13) in the body (5) prevents the rod (6) from being wholly7 detached, and also prevents rotational movement thereof with respect to the body.
The lower rod (7) is not screw threaded. 70 but is provided with spaced apart openings (14) through any one of which a shackled key (15) is adapted to be disposed to adjust the exposed length ot the rod with respect to the body The free end of the rod is bifurcated as at (16) to provide prongs (17) constituting the feet of the support.
Between the screw threaded portion (9) and saddle (8) of the rod (6) is a lateral arm (18) on which is removably carried a relatively heavy weight (19), a hook (20) or the like being provided for that purpose..
In operation the support set up with the arm (18) directed toward the work (2), and tne tool mounted in the saddle (8). The support is now properly adjusted in height to position the tool and a small hole is bored as a feeder whereupon the weight (19) is hung on the arm to torce the tool into the work. As the tool is ted into the work the support is gradually moved toward the work by pinching or jacking the foot toward the work by means ot a crow-bar. or the like (21). It is therefore only neces- 95 sary for an operator to guide the tool (no labor or pressure upon the tool being necessary) to feed it into the work` one hand can be used tor this purpose while with the other hand the crow-bar can be manipulated 100 to move 'the t'oot toward the work.
)While in the foregoing I have shown and described a specific embodiment ot' my involition, I do not desire to be limited in the broad concept of my invention, except as 105 may be indicated by the scope of the sub-- joined claims:
I claim 1. A support for power tools comprisinga supporting standard, an arm laterally can 110 ried thereby, and a. weight on the arm tor swinging the standard toward the work.
2. A support for power tools Comprising a supportingstandard, an arm'laterally carried thereby, a Weight on the arm Jfor swingL ing the standard toward the Work, and said standard being movably mountedrwith respeot-to a base to permit adjustment of the standard as a whole toward or away from the work.
3. Asupport for power tools comprising a sectional supporting standard, means for adjusting the height of the standard, an
arm laterally extending from .the standard,
and a Weight on the arm for swinging the standard toward thework.
4. A support for power tools comprising a tubular standard, members' adjustably can I ried Within the standard and extending from ablerwith respect to each other to regulatethe height of the standard, a Weight, and
meansfor supporting said Weightfrem one of said sections and ofi-Center with respect to the standard thereby to swing the'standard toward the Work.
In testimony Whereo I aiix my signature.
