MECHANISM FOR BREAKING AND HANDLING STONES- Application filed June 22, 1921. Serial No. 479,448.

To all whom it may concern:

Be it known that JAMES REANEY, a citizen of the United States, residing at Ruxton, in the county of Baltimore and State of Maryland, has invented certain new and useful Improvements in Mechanism for Breaking and Handlin Stones, of which the following is a speci cation.

This invention relates to an improved machine for breaking and handling rock andother materialsand has for its main object to provide a machine that combines a power hammer and a shovel device arranged on a self-propelledvehicle structure whereby it may be portable and wherein the shovel or hammer may beswiing from one side to the other to bring either of them into position for operation.

Another object of the invention is to provide an improved means for portably sustaining a power hammer whereby the latter may be capable of movement forward or backward with respect to the sustaining means; may be raised or lowered or be swung laterally to present the hammer at substantially a right angle to the surface against which the blow is to be directed, and A further object of the invention is to provide an improved construction of power iammer.

With these, and other objects in view, the invention is illustrated in the accompanying drawings, wherein,-

Fig. 1 shows a machine in side elevation. wherein the invention is embodied.

Fig. 1 illustrates on a smaller scale .the machine in conjunction with a wall of rock, or rock quarry, to indicate the operation of the machine.

taken on the line 11-11 of In carrying the invention into practical I efi'ect there is provided in the present instance a vehicle-20, mounted on a portable truck 21, as indicated in Fig. 1 of the drawing. In practice, this vehicle has a cab 23,

in which mechanisms are installed for propelling the vehicle and operating suitable Windlass mechanism and pumps for the compression of air, inxcase compressed air is utilized as the motive fluid for actuating the hammer devices, or a boiler in case steamis utilized as such motive fluid. The present machine is especially dewhere a ter blasting rock from its bed it is necessary to further break the stone into desirable sizes or sizes that can be handled by a pow-eractuaited shovel or bucket,so it can be loaded onto cars or trucks and conveyed to the mill where any further reduction in size that may be necessary can be effected by crushers or other means.

With these objects therefore in view, I mount the vehicle 20 on the truck 21, so the same can be revolved or swung from one side to the other of the portable truck, and from one side of the vehicle there is pivotally sustained a beam 24, which sustains a suitable shovel or bucket device 25, that may be elevated or lowered under the control of mechanism in the cab.

At the opposite side, the vehicle is provided with two spaced apart track- beams 25 and 26 respectively, which latter extend horizontally from but are rigidly held with respect to the cab. 1

On these track-beams there is mounted a carriage or truck which has two side plates 27 and 28, that are connected by upper horizontal cross-shafts 29 on the ends of which there are flanged wheels or rollers 30. These wheels or rollers 30 aresustained by and are designed to roll upon the top faces of the track-beams so that the weight of the carriage or truck is sustained by said beams.

At the lower edge each of the side plates 27 and 28 of the carriage or truck is provided with flanged rollers 31, which latter engage the under sides of the track-beams whereby upward displacement of the carriage from the beams will be prevented.

Each side plate 27 and 28 of the carriage or truck is provided with a circular boss 32, near its upper edge which forms a trunnion bearing and these bearings are centrally located with respect to the front and rear ends of the side-plates, as clearly shown in Figs: 2 and 3 of the drawings.

The purpose of the carriage or truck is to sustain the entire hammer devices, out of these devices an upper fluid motor only 33 is directly attached to the carriage by means of trunnions 34, which project horizontally and enter the bearings of the side plates.

This upper fluid motor 33 hasa cylinder whose head 35 is provided with side lugs 36 at diametrically opposite sides thereof and near the bottom, said cylinder has other side lugs 37 so that'guide tubes 38, may extend vertically from the upper to the lower side lugs, as shown best in Figs. 6 and 10 of the drawings, and for a purpose that will presently be explained.

In the cylinder of the upper fluid motor 33, there is a piston 39, having a stem 40 which passes through'a stuffing-box 41, and depends below said motor. The lower end of this stem 40 is rigidly connected to a horizontal plate 42, and at opposite sides of the stem this plate has an upwardly-extending guide-rod 43, which rods pass up through the lower lugs 37 on the lower end of the motor above and enter the guide tubes 38.

It is therefore to be understood that when the piston 39 is operated to move the stem 40 in a vertical direction the horizontal plate 42 will be given a like movement and the guide rods 43, will prevent the plate from turning during such movement.

The upper motor 33, its piston 39 and stem 40, are not utilized, in this instance, to give a hammer-blow, but are merely used to raise or lower the hammer devices to properly position said latter devices with latter serves as a cover for the cylinder, and

that said cylinder has a piston 45, and a rod 46, that depends from the lower end of the cylinder.

mer-head and has a central. depending hammer-lug 48.

The hammer-head 47, is provided with a plurality of vertical holes or passages 49, as best illustrated in Figs. 8 and 9 of the drawings wherein it will be seen that four of such passages are provided. Through each of theie vertical passages there extends a bolt 50, whose upper end is provided with a head 51 and whose lower end is bolted to an anvil-plate 52,a washer 53, preferably being interposed between the anvilplate and the hammer-head and the bolts 50 extending freely therethrough.

A coiled spring 54 encircles each vertical bolt 50 and has its lower end seated on top of the washer 53 and its upper end seated against the under side of the bolt-head 51, so that the washer and plate 52 are yieldingly held together by the four springs 54. 1

While the springs 54 yieldingly hold the anvil-plate 52 and washer 53 together, they play no part in sustaining the anvil-plate in position to receive the blow of the han'nnerlug 48. The means for thus holding the anvil-plate will therefore now be explained, reference being made to Figs. 3, 7 and 9 of the drawings.

The lower cylinder 44, carries a plurality of depending rods 55, whose upper ends are rigidly secured in the lower end of such cylinder and extend downwardly therefrom. These rods are therefor rigid with the cyl- This rod 45 carries a head 47 at its lower end WlllCll in reality is the hamllll inder and, while movable therewith, have no I q movement independently thereof.

' now be explained, reference being made par- These rods 55, extend freely through vertical passages 56 in the hammer-head 47, and their lower ends are reduced in diameter whereby to form shoulders 57 thereon. These reduced ends of the rods extend through perforations 58, in the washer 53 while the shoulders 57, seat on top of said washer so that the washer can have no vertical movement independently of the rods. Nuts 59, are screwed onto the lower reduced ends of the rods 55, and seat against the under side of the washer so as'to rigidly engage the washer with said rods.

In order to permit the anvil-plate 52,'to

seat close against the under side of the washer 53, the same is provided with suitable sockets or recesses 60, which receive the nuts 59 on the lower ends of the rods, as clearly shown in Figs. 7 of the drawing.

The washer 53, is provided with a central hole 61, through which the hammen-lu 48,

may project to stroke anvil-plate:

the upper side 0 the The anvil-plate 52, has a pointed projection or other shaped working-edge 62, which directly engages or contacts with the rock to be broken.

From the foregoing explanationit will. be understood that the upper cylinder 33is pivotally sustained from the carriage or truck by the trunnions 34 and that its lower end, and also the cylinder 44 and the hammering mechanism caried by the latter,

hang pendantly from said carriage.

The carriage, because of its rollers 30-31 and the track- beams 25 and 26, may be moved on the track-beams in a direction toward or from the cab 23 so that the hammer mechanism may be moved more or less laterally or to one side of the trackrails 22. To efiect this, mechanism is provided whereby the movement may be accomplished with ease and expedition, as will ticularly to Figs. 2, 6, 12, and 13 of the drawings.

By reference to Fig. 2, it will be noted I that a horizontal shaft 63 extends along the chain 66, passes.

inner side of track-beam 26 and has its outer end supported in a bearing 64, and -is carried on said beam. This shaft 63, extends into the cab 23 and on the interior of the latter said shaft carries a driving element such as a sprocket wheel 65, over which a This chain 66, alsov travels over a sprocket 67 which is carried on a main driving-shaft 68, and a clutch 69, havin a lever 70, is so connected with the sproc et 67, that the latter may be connected with or disconnected from the said driving-shaft 68 at will. The shaft 63, is circumferentially'-screw-' threaded along its stretchbctween the cab and the outer bearing 64,. and thisfscrewthreaded portion extends along and close to the vertical side plate 28 of the carriage or truck, as clearly shown in Figs. 2 and 13 of 'the drawings. This side. plate 28 of the carriage. or truck sustains a s lit or twopart bearing-bracket 71, which is internally screw-threaded so as to engage the threads on the exterior of the shaft.

Obviously, as shaft 63 has no longitudinal movement while the threaded bearing 71 is movable with the carriage or truck, when 'sald shaft is revolved the bearing 71 will be 'made to travel thereon, thereby moving the carriage in the direction in Which said bear ing is caused to travel. Obviously if shaft 68, be capable of reversal in its direction of rotation 1 it may drive the sprockets and chain in either direction and thus enable the shaft 63 to be rotated in either direction so that the carriage and the suspended hammering mechanism may be moved either forward or backward on the track-beams.

In addition to the back or forward adjustment of "the carriage and hammermechanism with respect to the cab, it is also desirable that said hammer-mechanism be capable of being swung with respect to the carriage from which it is suspended in order that the blow may be delivered at a right angle with respect to the surface 7 against which it is to be directed.

T 0 provide for this swinging adjustment of the hammer-mechanisml pendantly sustain the latter by the trunnions 34 but the means employed to effect this swinging adjustment will now be explained, particulower edge of this plate 73, is provided with a segment-rack 74, which latter meshes with a Worm 7 5, that is carried on a long horizontal'shaft 76. v j

This horizontal shaft 7 6; as canfbe seen in Fig. 2 of'the' drawing, extends horizontally at the inner side of the side plate 27' of the carriage'ortruck with jits' forward end seated in a bearing? 7 on a crossbar--78- at the outer endsv of. and con two track-beams.

This shaft 76-extends toward and enters t ng, the

the cab 23 and carries a sprocket 79 over which a chain 80 passes. This chain also extends around a' sprocket '81 on the main driving shaft 68, and a clutch device 82, controlled by a lever 83, serves to connect or disconnect the shafts 68' and 76.

The shaft 76, passes through suitable guide bearin s 84, which are carried at the inner side oi the vertical truck or carriage plate 27 which bearings are located at opposite ends of the worm 75, and said shaft is provided with a groove 85 which extends longitudinally thereof and .a key in the worm 7 5, engages the groove of said shaft and coacts therewith whereby to form a spline and feather connection which will permit the shaft 76 to be revolved so. as to revolve the worm and swing the segmentplate 7 3, which latter will rock the trunnion 72-34, and thereby swing the cylinder 33 in a direction corresponding to the direction in which the segment-plate is swung by the shaft. Obviously, when the cylinder 33 is swung the lower cylinder 44 and hammering mechanism will be correspondingly moved.

To raise or lower the hammering mechanism it is only necessary to actuate the pis ton -39 .in the cylinder 33 in the desired direction,connections 86 and 87 for the inlet or exhaust of the actuating medium, such as a fluid under pressure being provided in the cylinder.

To actuate the hammering mechanism, fluid pressure connections 88' and 89 are provided in the lower cylinder 44.

From .the foregoing explanation it is to be understood that the vehicle carrying the shovel and hammer structures maybe moved along the track-rails to any precise point desired; that the vehicle may be revolved on plate 52 may be seated on the material to be broken and the hammer-head reciprocated to deliver blows against the anvil-plate.

Having described my invention, I claim 1. In a device of the character described the combination with a trackwa a carriage on the trackway, a cylinder lvotally carried by the carriage and depending from the latj ter, power means for inclining the cylinder with respect to the carriage, a piston in said cylinder, a power hammer sustained by said piston and means independent of said piston for actuatin saidhammer.
