STONE CARVING AND DRESSING MACHINE.
SPECIFICATIGN forming part of Letters Patent No. 682,186, dated September 10, 1901.
Application filed December 30, 1899. Serial No. 742,037. (No model.)
To in whom, it may concern.-
Be it known that I, WILLIAM P. GAUL'ua citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and usefulImprovementsin Stone CarvingandDre'ssing Machines, of which the following is a specification.
My invention relates to certain improvements in machines for carving and dressing stone.
The object of my invention is to provide a machine for that purpose which shall be of a simple, strong, and durable construction and shall be adapted for use either in dressing or surfacing stone or for cutting, carving, or ornamenting the stone in the manner heretofore commonly done by hand.
My invention consists in certain novel features of the construction, combination, and arrangement of the various parts of the improved stone-dressing machine whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.
The novel features of the invention will be carefully defined in the claims.
In the accom panying drawings, which serve to illustrate my invention, Figure 1 is a side elevation of a machine constructed according to my invention; and Fig. 2 is a sectional plan of the same, the plane of the section being indicated by line a a in Fig. 1. Fig. 3 is a partial front view showing the table of the machine. Fig. 4 is a vertical partial section taken in the plane indicated by line b b in Fig. 1. Fig. 5 is an enlarged fragmentary detail view showing in elevation the means for holding the machine-table in position on the frame, and Fig. 6 is a vertical section showing the same parts. Fig. 7 is an enlarged View, partly in section, showing the coupling between the machine and flexible or tool shaft. Fig. 8 is a view similar to Fig. 7, but showing the opposite end of said flexible shaft having a tool in place; and Fig. 9 is a face view of the tool. Fig. 10 shows in edge elevation another form of tool adapted for use on my machine.
In the views, 1 indicates a suitable bedplate, from which rises a standard 2, having its upper end forked or branched, as shown at 3 3, to provide bearings 4 4 for a machineshaft 5, extending at right angles to the standard 2 and provided with a three-diameter pulley 6, by which it may be driven at different speeds from a drivingbelt. (Not shown.) One end of the shaft 5 projects at one side of the machine and has a coupling by which it is connected to a flexible toolshaft 6. The coupling is shown in detail in Fig. 7 and comprises a sleeve 7, secured to the end of the flexible tool-shaft 6 and having a threaded shank 8 to screw in a socket in the end of shaft 5. The flexible shaft 6 is inclosed in a flexible sheath or cover 9, as shown in Figs. 1, 7, and 8, and carries at its end a dressing or carvipg tool 12 of suitable construction. As shown, the tool 12 is held on a shank ll, protruding from a head 10,
secured to the end of the shaft and turning inside the sheath 9, the end of which carries a handle 16, whereby the sheath may be held stationary and the tool 12 guided by the operator in cutting, carving, or dressing the stone. Thetool 12 (shown in Figs. 1, 8, and 9) has cutting-surfaces 13 on its face; but it is evident other forms of tool may be used to suit different kinds of work to be done. In Fig. 10 is shown another form of tool 14, having peripheral cutting-surfaces 15. The work or stone to be cut or dressed is held on a table 17, projected laterally from the upright 2 beneath the projecting end of shaft 5 and capable of vertical adjustment to bring the work within easy reach of the operator when manipulating the tool on the flexible shaft 6.. By this means I am enabled to raise very heavy stones and adjust them in convenient position to be carved and dressed by the operator. The table 17 is formed at its rear part with a bearing 18 to slide vertically on the upright 2, and in constructing said table I preferably form it in two similar parts or halves l9 and 20, each of which carries half of the bearing 18 and half of the projecting part of the table and is provided with a strengthening rib or flange 23. The halves 19 and 20 are secured together at one end of the table by means of bolts 22, passed through lugs 21, projecting from the halves of bearing 18, and at the opposite end by bolts 24,
passed through the flanges 23. The projecting part of the table 17 is formed adjacent to the bearing 18 with a work-rest 25 and out sideof said rest is recessed in its upper face, as shown at 26, to receive a sliding-work-rest 27, capable of movement toward or away from the rest 25 to lengthen or shorten the table to accommodate different stones to be cut. The sliding rest 27 has an undercut or dovetailed projection 28, fitting and sliding in a dovetailed guideway 29 in the end portion of the table 17 and to permit of quickly adjusting the sliding rest I provide a screw 30, screwing in the rest 25 and collared in the rest 27. The screw is central in the table and has a hand-wheel 31, by means of which it may be turned to move the rest 27 back and forth. The rests 25 and 27 have shoulders 32 at their opposite ends, by means of which the work may be clamped on the table when desired, being held between said shoulders. The upright 2 is formed with a vertical rack 33, to receive which the bearing 18 ofthe table has a channel 34 in one side. The bearing 18 is also provided at the center of the channel 34 with a casing or chamber 35, in which is held a gear-pinion 36, fixed on a shaft 37, the end of which extends outside the casing and has a squared end to receive a crank-handle 38, by means of which the gear may be rotated. The teeth of the gear 36 mesh with the teeth of rack 33 on the upright and when the shaft 37 is turned serve to raise or lower the table 17, adjusting the same vertically along the upright 2. At the upper end of the channel 34 the wall 39 thereof is thickened to receive a screw 40, the tip of which is adapted for engagement between the teeth of rack 33 to hold the table in place when adjusted on the standard.
In operation the stone to be dressed or carved is placed on the table 17, which is adj usted by means of the screw 30 to a length to receive the stone, after which the table is raised or lowered, by means of the crank-handle 35, a proper height to permit the stone to be operated on and is secured by means of the bolt 40. The shaft 5 is then set in motion, the operator grasping the handle 16, so as to press the tool upon the surface of the stone and guide it along the same to dress the stone or to cut any design desired on the face thereof, the rotation of shaft 5 being communicated to the dressing or carving tool through the flexible tool-shaft 6.
From the above description of my invention it will be seen that the improved stone cutting, carving, and dressing machine is of an extremely simple and inexpensive construction and is especially well adapted for the use intended, since it permits of dressing and cuttingstone by means other than manual scales Having thus described my invention, I
claim- 1. In a stone carving and dressing machine, the combination of a frame having an adj ustable support for the stone to be carved or dressed, a main shaft journaled in the frame, a flexible tool-shaft attached and secured directly to and driven from said main shaft, said flexible shaft being movable in any direction Within the limit of its length, and a cutting-tool carried on the flexible shaft, substantially as set forth.
