MACHINE FOR DRESSING STONE.

SPECIFICATION forming part of Letters Patent No. 395,843, dated January 8, 1889.

Application filed July 13, 1888. Serial No. 279,855. (No model.)

To aZZ whom, it may concern.-

Be it known that I, FRANK MANNING, a citizen of the United States, residing at Narberth, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Machines for Dressing Stone, which improvement is fully set forth in the following specification and accompanyin drawings.

IO My invention relates to improvements in machines for dressing stone, and the objects of the invention are to provide improved mechanism for causing the carriage to travel longitudinally and transversely, or at a right 1 5 angle to said longitudinal or horizontal travel; further, to provide an improved construction of carriage and mechanism for operating the hammeror cutter, and also mechanism for throwing the hammer-operating mechanism into or out of operation, as desired; further,

to provide an improved construction of cutter or hammer; and, further, to provide an i111- proved construction of stone-carrying trucks.

The invention consists of the novel con- 2 5 struction and combination of parts hereinafter described, and specifically claimed.

Figure 1 represents a top plan view of .a machine for dressing stone embodying my invention. Fig. 2 represents a side elevation 0 thereof. Fig. 3 represents an end view of a detached portion on an enlarged scale. Fig. 4 represents views of the hammer or cutter. Fig. 5 represents an end view of the carriage. Fig. 6 represents an end view of the stone- 3 5 carrying truck.

Similar numerals of reference indicate corresponding parts in the several figures.

Referring to the drawings, the frame of the machine comprises the parallel bars 1, the

connecting-bars 2, and the supports or legs 3.

In one end of the frame is journaled the driving-shaft 4, carrying the pulley 5 and loose pulleys 6. 011 said shaft 4 is mounted a pulley, 7, and worm-wheels 8. The worm-wheels 8 mesh with worm-gears 9 in inclined shafts 10, having their bearings in boxes 11. The shafts 10 carry bevel gear-wheels 12, which mesh with bevel gear -wheels 13 and 14 mounted on a shaft, 15. The bevel gearwheel 13 is loose on said shaft, and is cut out at 13*, the purpose of which will be explained,

and the bevel gear-wheel 11L is secured fastto the shaft 15 and revolves therewith. Connected with the shaft 15 is a collar or flange, 15 provided with a projection, 15, the purpose of which will appear.

16 represents a sleeve surrounding the shaft 15, and adapted to revolve therewith. This sleeve carries the sprocket-wheels 17, one of which is provided with openings 17 adapted to receive the arms or pins 18 on the clutch 18*. The clutch 1S is provided with an extension, projection, or lug, 18 adapted to enter the cut-out portion or notch 13*, anda cut-out portion or notch, 18*, adapted to receive the extension or lug 15, and is provided 011 its periphery with an annular groove adapted to be engaged by the shiftinglever 18, for the purpose well known.

In the other end of the frame is fixed a shaft, 6?, and running loose on said shaft are the sprocket-wheels 17 and the belt-pulley 7*. Over the pulleys 7 and 7 travels the belt 7 hereinafter more fully referred to, and over the sprocket-wheels 1'7 and 17 travel belts, bands, or chains 17 From this construction it will be seen that the driving-shaft is revolved by means of the driving-pulley imparting motion to the sprocket-wheels and causing the belt 7 to travel and also the chains 17 It will also be seen that when the clutch 18 is caused to have the lug engage the cut-outportion 13 of the gear-wheel 13 the sleeve and chains are then caused to revolve at the same speed as the said gearwheel 13, and that by causing the collar 15 to have its lug 15 engage the cut-out portion or notch 18 of the clutch 13 the sleeve 16 will be revolved at the same rate as the shaft 15 upon which it is mounted; and also 0 the gear-wheel 14, as will be readily understood.

1 9 represents the carriage mounted on wheels 19 adapted to run on the parallel bars of the frame. 7

20 represents the carriage-frame provided with the rack 21 011 the under side, adapted to be engaged by the pinion 22 on a shaft, 23, carrying a worm, 24, operated by the worm shaft 25. The worm-shaft which operates the worm is preferably revolved by means of a wrench adapted to fit in the end of the said having thehelt 30* attached to itsends. This i helt Bo is connected with the hammer ll, which is provided with the heveled portion 5 adapted to slide in dovetailed. ways 32 on the carriage-frame. The hammer is of peculiar construction, and consists of the clampingjaws 31 having their contact-faces curved and adapted to receive the curved or cylindrical arm or post 31" of the cutter 31 By thus constructing the jaws and cutter it ing-jaws hy means of the screw-holt and jamnut ill", and thus made to dress the stone to suit convenience.

33 represents a helt-pulley loose on the shaft 27, and this pulley is cupped to receive the clutch 33*, which is connected with the shaft by means of a key engaging the keyway 27* of the shaft, and is adapted to revolve said shaft. The clutch is provided with an annular groove, l -i and in said groove is received the upper end of the shifting-lever ll. The ,5 shifting-lever is tulerumet'l to an arm or extension, on one of the uprights 26. In order to retain the lever in the position to which it has heen shifted,l provide the lever 3U, which is flllCllillllGtl to the shifting-lever and .o carries a lug or stud, 36", which passes through openings in the shifting-lever, and is adapted to engage any one of the series of openings 37 in the plate 37 secured to the carriageframe, and to hold the clutch out of ctmtact with the driving-pulley I attach a spring, 37,

to the plate and shitting-lever. From this construction it will he noticed that the lever can he shifted to cause the. clutch to engage the pulley, and thus cause said pulley to drive 0 the shaft, or can he shiftta'l to throw the pulley out of o 'ieration also, that; the amount of clutching-powerhetween the pullev and clutch can he adjusted by means of the shifting-lever and adjusting devices.

5 The operation is as follows: The stone in its rough state is placed on the trucks and adjusted hy means of the screws to the proper height. The carriage is also adjusted to bring the cutters in proper position for acting upon 0 the stone. The chains 17 pass over the sprocket-wheels, as shown, and are ctmnected with the carriage. The driving-belt passes around the pulleys in the frame and under and over the pulleys on the carriage-frame, as

5 shown. Theshifting-leverisoperatta'l to throw the clutch into engagement: with the pulley a )r), By the action of the chains 17* the carriage caused to travel horizontally, and the drivinghelt revolves the crank-wheel which o 'ierates the mechanism connected with the cutters, causing the same to cut: the stone as the carriage travels along. The carriage is then returned, the worm-shaft operated to cause the carriage to move transvta-sely, ready to dress a new surface on the stone. The carriage travels ln'irizontal ly, as hefore, and the cutters operate upon the stone in the manner descrihed until the entire surface has dressed, as will he readily undm'stood.

From the peeuliarconstruction ot' the stonesup n'irt of the trucks having the depressions or recesses, with the heads of the adjustingscrews arrangtal therein, it; will he seen that either side of the support may he elevated to present either edge of the stone to the action of the cutter, and that. the stone mayhe raised in a horizontal or inclined plane, as desired,

, and thus permit the entire surface of said is evident that the cutter can he turned to any angle desired, and retained in theclamp- 1 stone to he operated upon, or the edges thereof, and this is a great advantage.
