CHARLES C. HANSEN, OF EASTON, PENNSYLF'ANIA, ASSIGNOR 1'0 INGEESOLI -BLND GQMPANY, F JERSEY CITY, NEW JERSEY, A.

CORPORATION OF NEW JERSEY.

' PAVEMENT BREAKER,

Application filed July 11,

To all whom it may concern: Y

Be it known that I, CHARLEs C. HANSEN,

a citizen of the United States, and a resident of Easton, in the county of Northampton 5 and State of Pennsylvania, have inventeda certain Pavement Breaker, of which the following is a specification, accompanied by drawings.

This invention relates to pneumatically 10 operated pavement breaking machines and more particularly to a machine designed for breaking pavement by prying it loose from the foundation to which it is attached.

The embodiment hereinafter described is more particularly adapted to remove layers of asphalt pavement and its object is to support a pneumatically operated machine and provide controlling and adjusting devices by whic the operator may conveniently direct/the breaking tool to. perform its work. l

The invention will be more clearly understood by reference to the following description taken in conjunction with the accompanying drawing, in which- Figure 1 is a side elevation of a pavement breaker constructed in accordance with the practice of the invention,

Figure 2 is a plan view of the machine,

for the handles to the supporting axle,

Figure 4-is a vertical longitudinal section of the pavement breaker, and

Figure 5 is a cross sectionthrough the 3 guide and percussive tool taken alon the line 5-5, looking in the direction 0 the arrows."

-Referring to the drawing, the machine comprises a vehicle which may include an 40 axle A having a wheel B on either end and a pair of rearwardly extending handles C and D by which the machine is guided, a guide E rotatably mounted on the axle A so as to be angularly adjustable and a per-' cussive tool F slidably mounted in the guide 7 E and adapted to receive a shovel-like steel or bit G for operating against the pavement. Preferably at the rear of the uide E there is provided pneumatic fee means Figure 3 is a detail view of the connection 1924. swarm. 725,375.

' comprising a cylinder H bolted or otherwise attached to the guide within which a piston J is adapted to into the cylinder H and returned by means of a coil spring K located between the piston and the cylinder head L. The piston J 1s connected to cussive tool F by means .of a piston rod P working in the glandQ.

The gavement breaking machine F is prefera 1y of the hammer type'and maybe specially designed to slide in the guide E or, if desired, a standard fluid actuated paving breaker may be adapted to the purpose by providing a built-up cross-head R clamped about the tool as by means of the bolts S. The form of cross-headpmployed in this instance is shown in Figure 5 and comprises a pair of yokes R adapted to fit together and be fastened by the bolts the back head 0 of the per reciprocate hein pushed forward by compressed air admitted S and arranged when placed together to fit tightly about a cylindrical portion of the tool F. Each of the yokes R is provided with a suitable projection T which slides in the grooves U of the guide E. There are preferably at least two such cross-heads;-

one on the forward end of'the machine and the other on the rear.

Adjustment of the inclination 'of the guide E to the rod surface may be obtained by means of a rod V which is pivotally' joined at the-rearward end ofthe guide E as for-instance by means ofv a clevis W on the rod V joined by means of a pin Y to a boss Z .on the cyllnderi The rod V is adapted to be clamped: on a bracket I) mounted on a rod or tube 0 extendin trans versely between the handles 0 and By loosening the bolts d the rear end of the guide E may be raised or lowered to secure the proper angle to the road. surface and upon tightening of the bolts to clamp the rod V th s angle may be maintained.

The machine as above described is preferably heavy so as to prevent vibration and also to prevent the blows of the toolF from lifting the wheels from thegronnd. For

this reason trailer wheels 6 are provided, be

.ing mounted I on an axle f supported by brackets 9 extending downwardly from the handles C and D. The handles C and D may be formed from pipe bent to the desired shape as, for instance, shown in Figure 1 and which are attached to the axle A (Figure 3) by means of a casting 72. adapted to encircle the handles. A block j also fitting about the axle A is adapted with the bolts 79 to hold the axle and handle at right angles to each other.

The handle C, which is formed from a pipe, forms a convenient means for conducting the compressed a1r to the pneumatic percussive tool F and the cylinder H. Accordingly, a flexible connectlon such as the hose 0 may be connected with the handl 0 at any suitable point and "attached by means of a suitable coupling to th'ecylinder H. At the forward end of the handle C a flexible tube or hose p conducts compressed air to the percussive tool F. The end of the handle C nearest the operators position is adapted to be connected with a compressed air line 9 provided with a conveniently located throttle valve 1*. No independent controlling valve need be provided for the feed cylinder H since, while the machine is in operation, the tool F should be fed up to the work. In order to prevent the steel or bit G trom'dropping out of the chuck of the tool when the latter is withdrawn, a suitable steel retainer 8 is provided.

The operation of th machine will be understood from the above description. The

operator first adjusts the inclination of the guide E with respect to the pavement so that the bit G will undercut the pavement as shown at 2?. By opening a throttle valve r compressed air is admitted to the percussive tool F and simultaneously to the feed cylinder H. lhus, as the machine drives the bit G under the pavementt the piston J holds the machine against the work. The operator may, at the same time, push the machine forward to advance the bit G. Upon closing the throttle valve 7', the compressed air escapes from the cylinder H from the hose 0 and the hose p into the tool F exhausting the air to atmosphere and permitting the coil spring K to return the piston J and the tool F. I

In order to start a cut in the asphalt, the guide E may be positioned more vertically by loosening the clamping bolts (1 to allow the rod V to slide upwardly on the clamp. In this position the bit G works nearly perpendicular against the surface of the asphalt to cut down into it rather than to lift as in the operation above described.
