Application filed May 3, 1905. Serial No. 258,592.

To all whmn it may concern:

Be it known that I WILLIAM C. QUINLEN, a citizen of the United States, and a resident of Barre/in the county of Washington and State of Vermont, have invented a new and Improved Cutting-Machine, of which the following is a full, clear, and eXact description.

The invention relates to stone-cutting; and its object is to provide a new and improved cutting machine for surfacing or other work and arranged to, remove a large amount of stock in a comparatively short time and without unduly heating the cutters or subjecting the same to injurious strains.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement, parts being in section. Fig. 2 is a sectional front elevation of the same on the line 2 2 of Fig. 1. Fig. 3 is an enlarged plan view of one of the cutter-heads. Fig. 4 is a crosssection of the same on the line 4 4 of Fig. 3, and Fig. 5 is a sectional elevation on the line 5 5 of Fig. 1.

The improved cutting-machine is mounted on a suitably-constructed frame A, in which is journaled a main shaft B, carrying a conepulley C, connected by a belt with other machinery for imparting a rotary motion to the shaft B. On the forward end of the shaft B is secured a pinion D, in mesh with a spurwheel E, secured to or formed on a wheel F, provided with bearings for a plurality of radially-dis osed shafts G, each carrying at its outer en a cutter-head H, provided with a plurality of sockets or bearings H for receiving and holding cutters I.

On the inner ends of the shafts G are secured bevel-pinions J, in mesh with a bevel gear-wheel K, formed on the face of a double wheel K, also having a spur-wheel K in mesh with the driven pinion D, above referred to. The hub K of the wheel K is ournaled in a suitable bearing A, arranged on the main frame A, and the shaft F of the Wheel F is j ournaled at its rear end in a bearing A carried by the main frame A, the forward end of the said shaft being journaled in the hub K of the double wheel K.

When the shaft B is rotated, then the pinion D by meshing with the spur-wheels E and K rotates the wheels F and K in opposite directions, and as the spur-wheel E 'is fixed on the wheel F it is evident that the latter is rotated, and thus carries the cutters H around in. a circle. At the same time the rotary motion given to the spur wheel K. causes the rotation of the double wheel K, which by its bevel gear-wheel K, in mesh with the pinions J, causes rotation of the shafts G, and consequently rotation of the cutter-heads H. Thus the cutter-heads H and their cutters are carried bodily around in a circle by the wheel F and are rotated at the same time, the revolving speed of the cutterheads H being considerably in excess to that of the wheel F.

The cutter-heads H and their cutters I are adapted to pass through water or other cooling liquid contained in a tank L, having a segmental apron L, provided with an opening for the passage of the outer ends of the bearings for the shafts G, the tank also being open at the top for the entrance of the cutter-heads H, as will be readily understood by reference to Fig. 2. The tank L is provided with pipes L for supplying the tank with the desired cooling liquid, and in the bottom of the tank is arranged a stopper L for discharging sediment from the tank whenever it is desired to do so.

The material to be treated is held on a platform N, mounted to turn on a wheeled vehicle 0, adapted to travel on rails P adjacent to the machine, it beingunderstood that by having the platform N made adjustable the desired face of the work can be brought in proper relation to the cutting edges of the cutters I for the latter to cut off surplus material from the face.

The operation is as follows: When the shaft B is rotated, a rotary motion is given to the wheel F and the cutter-heads H, as described. Then the cutter'heads H are carried bodily past the face of the work to be trimmed, and at the same time the rotation of the cutter-heads causes the sharp edges of the cutters I to act on the face so as to remove surplus material therefrom. Thus during the time a cutter-head H passes the face of the work it is evident that the cutting edges of the several cutters on this head come successively in contact with the face of the Work at different points, so that each cutter chips off a portion of the face, and each cutter remains but a short time in contact with the work. After the cutter-head H has passed the face the cutters remain idle and with the head pass through the cooling liquid in the tank L previous to reengaging the face of the work,-so that the cutters are in a properlycooled condition upon again reaching the face of the work. It is expressly understood that the cutters of each cutter-head successively engage the work, owing to the rotation of the cutter-head, and remain but a short time in contact with the work, so that each cutter is not unduly heated and is not subjected to injurious strains.

.The cutters of the cutter-heads are preferably brought into contact with the surface to be treated at about the time the shaft of a cutter-head moves into a horizontal position; but this is not essential, as the cutter-heads may engage the work when reaching a top or other position. The cutter-heads of each cutter are preferably disposed in the same plane; but this may be varied, if desired.

By arranging the tank in the manner described the cooling liquid therein is not spilled out of the tank by the cutter-heads during their passage through the tank.

The machine can accommodate a large number of tools, is not subjected to undue strains, and hence long life is insured to the machine, and a large amount of work can be done in a comparatively short time.

Having thus described my invention, I

arranged radially and journaled in the said wheel, each cutter-head having a plurality of cutters disposed in the same plane, means for rotating the said wheel, and means for rotating the said shafts at a higher rate of speed than that given to the said wheel.

3. A cutting-machine, comprising a revoluble wheel, a plurality of radial shafts mounted in the wheel, cutter heads on the outer ends of the shafts and each carrying a plurality of cutters, and means for rotating the shafts.

4. A cutting-machine, comprising a revoluble wheel, a plurality of radial shafts mounted in the wheel, cutter-heads on the outer ends of the shafts and each carrying a plurality of cutters, a driven shaft, and means for revolving the wheel and rotating the said shafts from the driven shaft.

5. A cutting-machine, comprising a revoluble wheel, a plurality of radial shafts mount ed in the wheel, cutter-heads on the oilter ends of the shafts, a driven shaft geared with the wheel, and gearing between the driven shaft and the inner ends of the radial shafts.

6. A cutting-machine, comprising a revoluble wheel provided with a gear-wheel, a plurality of radial shafts mounted in the wheel, cutter-heads on the outer. ends of the shafts, pinions on the inner ends of the shafts, a double gear-wheel meshing with the pinion, and a driven shaft provided with a pinion meshing with the gear-wheel of the said wheel and with the double gearwheel.

8. A cutting-machine comprising a revoluble wheel, a plurality of revoluble cutterheads mounted on the said wheel, and a tank for containing a liquid and provided with a segmental apron having a longitudinal opening, said tank being open at the top for the passage of the cutter heads through the liquid between the apron and the bottom of the tank.

9. A cutting-machine comprising revoluble cutter-heads having a plurality of sockets for the cutting-tools,shafts carrying the said cutter-heads, a wheel in which the. said shafts are journaled and arranged radially, means for rotating the said wheel, pinions secured on the said shafts, a gear-wheel driven by the said means and in mesh with the said pinions, and a tank for containing a liquid and open at the top for the passage of the said cutter-heads and their cutters through the liquid in the said tank.

10. A cutting-machine comprising revoluble cutter-heads having a plurality of sockets for the cutting-tools, shafts carrying .the said cutter-heads, a wheel in which the said shafts are journaled and arranged radially, a spur gear-wheel fixed on the said wheel, a double gear-wheel having a spur gear-wheel and a bevel gear-wheel and arranged concentric to the said spur gear-wheel, a driving-pinion in mesh with the said spur gear-wheels, and bevel-pinions on the said shafts and in mesh with the said bevel gear-wheel.
