PUNTING=MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,454, dated February 26, 1889. Application filed April 19, 1888. Serial No. 271,246. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY O. SCHRADER, a citizen of the United States, residing-at WVheeling, in the county of Ohio, State of Test Virginia, have invented certain new and useful Improvements in Punting-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to a machine for cutting and finishing the bottoms of glasses, and the objects and advantages thereof, together with the novel features, will hereinafter be described, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a front elevation of a machine constructed in accordance with my invention. Fig. 2 is a side elevation, and Fig. 3 is a similar view of the opposite side.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 2 represent two opposite standards of the framework, which are mounted upon a suitable base, 3, and are connected at their top and intermediate the same and their base by cross-beams 4 5.

Journaled in opposite bearing, 6, formed in the standards 1 and 2, is a crossshaft, 7, rigidly mounted upon which are a pulley, 8, a cutting-wheel, S1, and a grinding-wheel, 10.

Below the shaft 7 there is located a sand-box,

11, in which is a water tank or basin, l2.

J'ournaled in vertically-opposite bearings 13, formed in the two parallel cross-beams 4 and 5, are vertical shafts 1.4 and 15, the former being mounted directly over the cuttingwheel 9 and the latter directly over the grinding-wheel 10. Upon the upper end of the shaft 14 is secured a weight receptacle, 16, or it may be a weight, and at the lower end of said shaft is a glass-receiving head or chuck, Just above the upper bearing, 13, of the shaft the same is provided with a worm-gear, 18, and intermediate said bearings there is a fixed collar or boss, 19. A lever, 20, mounted upon an arm, 21, terminates under the collar or boss 19, which, when operated through the medium of a chain, 22, and foot-lever 23, serves to raise and lower said shaft.

Above the machine there is suspended-4n this instance from a beam, 24-a sand-hopper, 25, provided with a chute designed to deliver sand upon the cutting-wheel 9, the quantity of sand delivered being regulated by a rod, 26, operating a gate, 27.

The upper end of the vertical shaft is swiveled in an eye, 28, from which a rope, 29, extends up over a pulley, 30, mounted on the beam 24, and extends down at the side of the machine. A sleeve, 31, is mounted on the shaft 15 intermediate its bearings, which sleeve is longitudinally slotted, as at 32, to receive a lug, 33, formed on the shaft, so that said shaft may slide vertically in the sleeve and rotate in connection with it. At the upper end of the sleeve is mounted a worm-gear,

34, and at the lower end thereof 1s a twingrooved pulley, 35. At the lower end of the shaft is mounted a rubber or other chuck, 36, adapted to receive and retain a tumbler or glass.

Pivoted to the sleeve 31, near its lower end and extending laterally therefrom, are arms 37, from which depend rigid arms 38, to the ends of which are pivoted open heads 39, in

which are j ournaled spindles 40, carrying pulleys 41, mounted within the head and terminating-in glass-receiving chucks 42in this instance formed of rubber. An endless belt, 43, is passed around the twin pulley and laterally over twin pulleys 44, mounted on the arms 38, provided with belt-tighteners 45, and down over the pulleys 39, thus transmitting motion from the sleeve 31 to the spindles 40.

The belt-tightener 45 is fastened to the end of the axle of the pulley 44 by means of a tightening-screw, 58. In order to make it operate, it is pressed outward against the belt and fastened in this position by tightening said screw. Any well-known means may be employed for the purpose of holding these arms out in an operative position, however, without departing from the spirit of my invention.

Journaled in bearings 46, formed on the cross-bar 4 of the frame-work, is the powershaft 47, which is provided at its end with a working-pulley, 48, and idle-pulley 49 and with worm-gears 50 and 51, the former meshing with the worm-gear 18 on the shaft 14 and the latter meshing with the worm-gear 34 of the shaft 15. Power is conveyed to the shaft through any ordinai-y system of belting leading from a motor, and the shaft 7 is also likewise operated independently in this instance.

At the side of the frame-work described. there projects an angular arm, 52, at the end of which is formed a bearing, 53, which, in connection with an opposite and similar bearing, 53 formed in the standard 2, forms bearings for a horizontal shaft, 54., which is operated through the medium of a pulley, 55, and carries a polishing-wheel of wood, 56, or other suitable material.

The operation of myinvcntion is as follows: A glass, a, is placed upon the chuck 17, and the bottom thereof is suitably cut by the cutting or coarse grinding wheel 9, the weightin the receiver 16 giving the required pressure. By pressing upon the foot-lever 23 the shaft 14 is raised and the glass removed and its place refi1led,and the removed glass is placed upon one of the spindles or chucks 42,whereupon the glass is ground. The second glass is then removed from the chuck 1'7 and placed upon the other chuck, 42, and so on until the chucks 42 are each provided with a glass, and also the chuck 36, the latter being accomplished by raising the same through the medium of the cord or rope 29, the shaft and spindles rotating all the time. As it takes longer to grind than cut, the capacity of the machine for grinding is consequently increased by the three chucks 30 and 42. The chucks 42 and are held in contact with the revolving grinding-wheel by gravity and may be swung out and the glasses easily removed therefrom. The rear head, 39, is provided with a forwardly-projecting handle, 57. After the glasses are removed from the spindles of the shaft 15, they are finished upon the polishingwheel 56. In the operation of cutting, sand fiowsfrom the box 25 over the cutting-wheel 9, which greatly facilitates the cutting operation, the sand then dropping into the receptacle 11.

Having described my invention and its operation, what I claim is- 1. In a machine of the class described, a grinding-wheel and a vertical rotating shaft bearing a chuck mounted above said wheel, in combination with a sleeve surrounding said shaft and arms attached to said sleeve and provided with glass-receiving chucks, substantially as described.

2. In a machine of the class described, the combination, with a grinding-wheel rotatably mounted upon a shaft, of a shaft mounted for reciprocation in a sleeve and adapted for rotation therewith an d provided with oppositelypivoted rotatable spindles having glass-receiving chucks at their ends, substantially as specified.

3. The combination, with the frame-work,

of a sleeve longitudinally slotted and carrying a gear mounted thereon, a shaft mounted for reciprocation in the sleeve and provided with glass-reciving chucks mounted in spindles provided with pulleys, an endless belt mounted over the pulleys and over a pulley mounted on the shaft, and of a power-shaft provided with a gear adapted to mesh with the gear on the sleeve, substantially as specified.

4. The shaft 15, mounted as described, and having pivoted arms" 37 and twin pulley 35, the depending arms 38, having pivoted heads 39, carrying spindles 40, provided with pulleys 41 and chucks 2, the pulleys 44, mounted on the depending arms, and the chuck 36, mounted on the shaft, and the belt 43, mounted as described and adapted to give motion to the chucks, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY c. sciiRAnER.
