EMERSON T. MORRIS, OF DERWENT, OHIO, ASSIGNOR OF ONE-HALF TO 7 GEORGEH. MORRIS, OF DERWENT, OHIO.

STONE-QUARRYING MACHINE.

Specification of Letters Patent.

Patented June 12, 1906.

To all whom it may concern:

Be it known that I, EMERSON T. MORRIS, a citizen of the United States, residing at Derwent, in the county of Guernsey and State of Ohio, have invented certain new and useful Improvements in Stone-Quarrying Machines, of which the following is a specification.

This invention relates to machines designed for channeling rock, stone, and the like in quarrying, the purpose being to provide a mechanism which can be readily set up, taken down, and adjusted to cut blocks or layers of desired size.

The machine embodies one or more cutters mounted upon a frame so as to receive a rectilinear reciprocated movement, said frame having imparted thereto a simultaneous vibratory movement at right angles to the lane of movement of the cutter to insure the ormation of a channel whereby the layer or block is completely separated at one side from the mass of stone.

The invention consists of the novel features, details of construction, and combinations of parts, which hereinafter will be more particularly set forth, illustrated, and finally claimed.

In the accompanying drawings, forming a part of the specification, Figure 1 is a perspective view 0 a stone-quarr ing machine embodyin the invention an havin the parts assemb ed for cutting horizonta channels. Fig. 2 is a central longitudinal section of the form of machine illustrated in Fig. 1. Fig. 3 is a transverse section on the line a; :r of Fig. 2 looking in the direction of the arrows. Fig. 4 is a vertical central longitudinal section of a stoneuarrying machine embodying the invention aving the parts arranged for cutting vertical channels. Fig. 5 is a transverse section on the line y y of Fig. 4 looking in the direction of the arrows. Fig. 6 is a detail perspective view of the framework of the form of machine shown in Figs. 4 and 5, supporting the cutting mechanism and the working parts. Fig. 7 is a detail perspective view of one of the bits or cutter-points and. the nut cooperating therewith. Fig. 8 is a detail view showing the yielding connection between the cutter and the pitman or connection imparting movement thereto. Fig. 9 is a detail perspective View of the connectin means between the movable framework an the fixed structure. Fig. 10 is a detail view of the mechanism for feeding the movable framework and returning the same to a given position. Fig. 11 is a detail section of the cross-head on the line 2 z of Fig. 9.

Corresponding and like parts are referred to in the followin description and indicated in all the views of the drawings by the same reference characters.

The fixed framework or structure comprises posts 1, four in number, which are extensible, so as to be rendered stationary when arranged in the desired position. The posts 1 may consist of ordinary tubing, and each is provided with a pointed end or section 2-, threaded thereon so as to penetrate the roof or overhead part of a quarry and for the position of the posts after being positioned. Longitudinal and transverse rods or bars 3 and 4 connect the posts 1 and form therewith a rigid structure. The connecting- rods 3 and 4 are vertically adjustable to admit of moving the cutting mechanism to the required point. Any suitable means may be employed for firmly connecting the rods to the posts. As shown, a cross-plate 5 is provided at each end of the rods and is centrally depressed, and a companion plate 6, having its middle portion correspondingly depressed, is adapted to be suitably connected to the plate 5, so as to clamp the post between them.

A movable framework 6" is supported upon the connecting-rods of the stationary frame or rigid structure in such a manner as to have a vibratory or reciprocating movement imparted thereto at a right angle to the plane of movement of the cuttin mechanism, so as to form a channel in the ace or bed of the rock, stone, or like material to be quarried. Arms 7 project from the framework 6 and are loosely mounted upon corresponding connecting-rods of the stationary framework. A shaft 8 mounted in suitable bearings upon a third framework 9, has crank connection with. one of the connecting rods or bars of the stationary frame, so as to impart a reciprocati'ng or vibratory motion to the framework 6*. A sleeve 9 is slidably mounted upon the selected connecting-rod of the stationary frame, and a pitman 10 connects said sleeve with the shaft 8 in any manner, so as to impart a reciprocating movement to the frame 6 It is to .be understood that the framework 9 is gradually advanced to feed the cutting mechanism as the channel deepens. Hence the necessity for providing a sliding connection between the pitman 10 and the cooperating rod of the stationary frame. A telescopic guide connection is provided between the main or stationary frame and the movable frame or frames. This connection comprises a rod 11 and a tube 12, the latter having a cross head or sleeve 13 at its outer end to receive the rod 3 of the stationary frame to which said connection is attached. As shown in Fig. 1, a telescopic connection is interposed between the frame 6 and the stationary frame and between the frame 9 and said stationary frame. The latter connection is slidable upon the rod of the main frame, so as not to interfere'with the forward movement of the frame 9 when advancing or feeding the cutting mechanism to its work. This latter connection receives the outer end of the itman 10, facing the front end of the mac ne, the said pitman and telescopic connection moving together as the frame 9 is fed forward to advance the cutting mechanism.

The frames 6 and 9 may be of any construction best adapted for the special work for which the machine is designed. The frame 6 receives a vibratory or rectilinear reciprocating movement, whereas the frame 9, being mounted upon the frame 6 and carried thereby, moves in consonance with said frame and has an independent movement, made necessary to feed the cutting mechanism as the channel deepens. The framework 9 supports the motor 14 and the actuating mec anism for operating the working parts. The motor 14 may be of any type or structure best adapted for the purpose. A crankshaft 15, mounted in bearings of the frame 9, derives motion from the motor 14 in any manner, and its crank portions are connected to the cutters 16, so as to impart a reciprocating motion thereto. In the event of the machine being provided with two sets of cut ters, so as to form parallel channels at one operation, the connections are so arranged as to impart an opposite movement to the cutters, so that as one advances the other is withdrawn, thereby enabling the cutters to operate in alternation. Each of the cutters 16 is mounted in suitable guides which give rectilinear movement thereto. As shown, each guide is formed of either a rabbeted strip 52 and a confining-strip 53, attached thereto, or a grooved strip 54. A pitman or connectin -rod 17 transmits motion from the crank-shaft 15 to each of the cutters 16 and has yielding connection with the latter to relieve the operating mechanism of jar and jolt. This yielding connection is formed by means of a boxing 18, a block 19, slidable in said boxing, and a spring 20, located at each side of the block. The pitman 17 is connected to the block 19. Hence power is transmitted from said block through either one of the springs 20 and boxing 18 to the cutter. This construction enables the springs 20 to act as cushions and neutralize all jar incident to the impact of the cutter with the stone or the like bein cut.

A shaft 21, mounted in suitable bearings upon the frame 9, is adapted to be driven at a comparatively slow speed for gradually advancing the cutters as the work progresses and is adapted to have a fast speed imparted thereto for quickly returning the cutting mechanism to the initial or required position after the work has been completed or when required for any purpose. The two speeds may be imparted to the shaft 21 in any convenient way. As shown, a shaft 22 has a worm-gear connection 23 at one end with the shaft 15 and is provided at its opposite end with a worm-thread 24, in mesh with a wheel 25, fast upon the shaft 21 and provided with worm-cogs in mesh with the worm-thread 24. For imparting a comparatively fast speed to the shaft 21 a shaft 26 has gear connection 27 at one end with the shaft 15 and corresponding gear connection 28 at the opposite end with the shaft 21. The gear elements 25 and 28 may be either fast or loose upon the shaft 21, the latter construction being preferred and suitable clutches 29 and 30 being provided to throw them into and out of cooperative engagement with the shaft 21. An operating-lever 31 is provided for actuating the clutch 30 to throw the gear-wheel 25 into or out of engagement with the shaft 21. An operating-lever 32 is provided for the clutch 29 to admit of throwing the gearing 28 into or out of action with the shaft 21. One or more ear-wheels 33 are fast upon the shaft .21 and mesh with the teeth of one or more rack-bars 34, fixed to the framework 6*, whereby when said shaft 21 is rotated either forward or backward the framework 9 is correspondingly advanced or retracted. When the clutch 30 is in engagement, the shaft 21 is rotated slowly, so as to gradually advance the framework 9 and the cutting mechanism as the work progresses. When the gearing 28 is clutched to the shaft 21, the latter is rotated at a faster speed, so as to rapidly return the frame 9 to the given or required position. It is to be understood that when the clutch 30 is in engagement the clutch 29 is unshipped, and vice versa.

The cutting mechanism comprises a plate or frame 16, provided at one end with a series of bits or cutting-points 35. The plate or frame 16 is slidably mounted in suitable guides of the framework 6*, as herein indicated, so as to receive a rectilinear reciprocating movement in a plane at a right angle to the reciprocating or vibratory movement of the frame 6", whereby the bits or cutters 35 form a channel instead of a series'of openings. Each of the bits or cutters 35 is formed with a shoulder 36, an angular shank 37, and

a reduced threaded end 38 to receive a nut 39, the latter being provided with radial lugs 40 to receive the taps of a drift or like tool employed for tightening and loosening the nuts. The plate or frame 16 is provided near its outer end with a series of openings 41, with which other openings 42 communicate. The openings 42 are of such conformation as to receive the angular portions 37 of the bits to prevent possible turning thereof. The openings 41 receive the nuts 39 and the threaded ends 38. The shoulders 36 bear against the front end of the plate or frame 16 and in conjunction with the nuts 39 retain the bits or cutters in place, as will be readily comprehended.

The machine illustrated in Figs. 1, 2, and 3 is adapted for forming horizontal channels and for cutting two of such channels at the same time. The machine shown in Figs. 4, 5, and 6 is adapted for cutting vertical channels, whereby the layers are cut into blocks. The arrangement of the parts is substantially the same in both forms, the slight changes being obvious to adapt the operating mechanism to the changed position of the cutters according as the channels are to be out either horizontal or vertical. In the machine as adapted for cutting vertical channels the crank-shaft 15 of the horizontal channelingmachine is dispensed with and is replaced by a shaft 43, which is provided with crankwheels 44, connected by pitmen 45 with the cutters 16. Shafts 46 have a worm-gear connection 47 with the shaft 43, and pitmen or rods 48 connect crank-wheels 49 of the shafts 46 with a car 50, mounted to run upon a track of the movable frame 6. Telescoping guides 51 are interposed between the frame 9 and the car to relieve the pitmen 48 of undue strain. The shafts 46 are adapt ed to be driven from the motor (not shown) by suitable connections and impart a vertical reciprocating or vibratory movement to the frame 9, whereby the cutters 16 receive a corresponding movement simultaneous with their longitudinal reciprocating move ment, thereby providing vertical channels instead of horizontal. It is contemplated to dispense with one or the other of the cutters, so that when desired a single channel only, either horizontal or vertical, may conform,

thereby adapting the machinefor quarrying rock, stone, or the like in blocks or layers of any desired size.

It is to be understood that motion may be imparted to any one of the connected shafts for driving the several working parts, the power being preferably derived from a motor (not shown) mounted upon the framework in substantially the same manner as hereinbefore set forth. For the sake of illustration a drive-belt 55 transmits motion to the shaft 43. It is to be understood, further, that the working parts may be mounted in any manner best adapted to meet existing conditions and the special work for which the machine is devised.

In the modification shown in Figs. 4, 5, and 6 a framework 56 is mounted upon the longitudinal bars 3 of the fixed framework or structure and is relatively stationary and embodies longitudinal sills 57, upon which the car 50 is adapted to travel. The movable framework 6*" is mounted upon the frame work 56, so as to receive a vertical reciprocating movement only, and the rack-bars 34 are firmly attached thereto and mesh with the gear-wheels 33 to effect forward movement of the car 50 and the frame 9 in the operation of the machine. The cutters 16 are directed in their reciprocating movements by guides applied to and forming a part of the framework 9. The framework 9 supports the driving mechanism and reciprocates vertically with the framework 6" and is in turn advanced with the car 50 to feed the cutting mechanism to the work.

Having thus described the invention, what is claimed as new is 1.
