CHARLES C. HANSEN, OF EASTON, PENNSYLVANIA, ASSIGNORTO INGERSOLL-RAND COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION 0E NEW JERSEY.
MOUNTING FOR CONCRETE BREAKERS.
To all ywhom t may concern:
Be it known that I, CHARLES C; HANsEN, a citizen of the United States, and a resident ot Easton, inthe county otllorthamptonY and State ot Pennsylvania, have invented a certain li/lounting for Concrete Breakers, of which the following is a specification, accompanied by drawings.
This invention relates to concrete breakers, but more particularly to a mounting for fluid actuated concrete breakers of the hammer type.
One object of the invention is to mount a concrete breaker on a vehicular mounting to relieve the operator lot the constantv strain of supporting the tool. y
Another object is to preventthe transmission ot shock and vibration tothe operator when the tool is in operation.
Further objects will appear hereinafter.
The invention consists ot' the combinations ot elements', features or" construction, and arrangement of parts Vhaving the general mode of operation substantially as hereinafter described and more particularly pointed out in the appended claimsand i.- lustrated in the accompanying drawings, in which l Figure l is a side view in elevation partly in sectionof the universal VVmounting tor a concrete breaker,
Figure 2 is a front end view in elevation,
and n v Figure 3 is a top plan view ot the mounting.
Referring to the drawings, the mounting comprises a pair of wheels A having an axle B to which are secured handle bars C as by` means ot clamps D. The handle bars C are preferably o'lE tubular form and are p rovided at the rearward end with a hollow cross piece E secured to said handle bars by suitable clamps F to serve as a gripy whereby the operator may manipulate the device.
In practice, it is desirable to provide the smoothest possible surface fory the wheels A and also to provide the best footing obtainable for the operator. To this end the handle bars C are extended through the clampsV D to provide a support for the fluid actuated percussive tool G in such a Vmanner that the wheels A will be between Ythe operator and the tool G.
In order to enablethe tool G to be adthe bracket on the posts'.
Application filed July 10, 1925. Serial No. 42,643. .A
justed vertically to suit varyingconditions,
a pair of posts H are arranged slidably within bearings J clamped to the front end ot the handle barsl C. Any suitable means may be provided for holding the posts H against endwse movement as tor instance, set screws K. In this instance, a bracket L Vhaving a pair ot bearings O is arranged slidably` on the posts H to providea support for a yoke P arranged between the bearingsl and secured thereto by means of pivot bolts P.` In order to oppose downward movement of the bracket on the rposts H, a spring Q is interposed between said bracket and a collar .Rcarried by the posts. A similar spring S is arranged above the bracket ,ll-and is held in position bya collar, T for opposing upward movement ot A pivot U is arranged through a handle Vof the tool G and extends through the yoke P for supporting' the tool. Suitabley means are provided for rocking the tool G through a plane paralleling the axle B for locating vthe working point of a `cutting iin-l plement or chisel For this purpose,'a' pinion X pivoted on a shaft Yis arranged rotatably in the bracket lL for actuatingfa rack Z heldslidablyl on thebracket L by suitable clamps .7).- The bracket L carries apair ot plates eto `torni bearings tor a rocker arm d attached to the handle V ot the tool G. In order to rotate the pinion X a rod eextendingto the operators position is connectedtothe shaft Y by means Vot a universal jointV f. A hand wheel g is scoured to the rearwardl end ot the rod e yto provide a convenient means tor manipuating said rod. v A, somewhat similar arrange? ment is provided for swinging the tool G in-,a plane transverse to the axle B. For` this purpose,;an arm h is secured to the yoke P and has an eye j at its tree end to receive Yco the end of a rod 7e which like the rod e, alsov desired deptln'the operator may either pull rrr'or push on the lrod E and thus drive the broken material free "from the mass:
'1f itis not convenient or desirable* to shirt the ventire mounting for a succeeding cut along the race of the Work, the -rod 'e may be rotated `'to rock the tool G about the pivot U, depending ofcourse, upon the direction in which it is desired to move the tool with respect tothe precedingcut, and
the chisel lV may then be'driven into the Work as previously described. If, on ,the other hand, it is desired to rlocate thefchisel lV in advance or to the rear of the lpreceding cut, the 'operator may pull or push bien therod c, as the case may .be,'to rock 3 Y the yoke P and `consequently the tool G about the pivot P. APressure fluid may then be'supplied fordrivin'gth-e chisel into the work. K' The vrod 7c also provides a convenient/means for prying the broken .concrete free froinithe Work, if for any re'ason it is preferable to hold the mounting lin `a stationary position.
