JAMES H. HEROY AND 'ILLIAM Y. IIEROY, OF NE\V YORK, N. Y.

MACHINE FOR GRINDING AND BEVELING PLATE-=GLAS S.

SPECIFICATION forming part of Letters Patent No. 394,980, dated December 25, 1888.

Application filed January 12, 1888. Serial No. 260,509. (No model.)

To aZZ whom it may concern:

Be it known that we, JAMES H. HEROY and \VILLIAM V. HEROY, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Grinding and Beveling Plate-Glass, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for grin ding and bevelin g pl ate-glass and similar plates having practically plane surfaces.

The object of the invention is to produce a machine in which the work of grinding and beveling glass plates can be done continuously and with little attention, and in which the plates can be beveled to any usual angle.

The invention consists in the combination of parts by which a continuous reciprocation of the grinding-wheel is produced; also, in the combination of mechanism for holding the plates and adjusting them at a suitable angle to the grinder; also, in the mechanism by which the grinder is supplied with abradent material while in use; also, in various details of construction and combinations of elements hereinafter explained.

In the drawings, Figure 1 is a plan of the machine, omitting the plate table and clamp, the standards which support said table being shown in sect-ion. Fig. 2 is a side elevation of the machine, showing the plate-table and plate-clamping devices. Fig. 3 is a vertical cross-section on line a: as, Fig. 1, some parts being omitted. Fig. 4. is a detail of the pinions connecting shaft 17 to the counter-shaft. Fig. 5 is a detail of one of the stops.

The numeral 1 indicates the frame of the machine. This frame is somewhat similar to the bench of ametal-turniug lathe, and has parallel tracks or bars 2 2, on which the grinder-truck is supported and reciprocates.

The truck 3 is held to the tracks 2 2 by dovetail guide-pieces 4 4, which extend parallel with the said tracks. The truck 3 is caused to reciprocate longitudinally of the tracks by means of the threaded shaft 5, journaled in the frame and engaging a nut, 6, attached to the truck. The shaft 5 carries two fixed pulleys, as 7 and 8, and two idlers, as 9 and 10. Of course the position of these pulleys may be varied.

shaft 25.

The belts 11 and 12 are adapted to drive the fixed pulleys, but run in reverse directions. A double belt-shifter, 13, engages these belts, so as to throw one of them into engagement with a fastpulley and the other with an idler. The belt-shifter 13 is supported by a rod, 14., which is supported on ways in the frame in such manner that it may slide in the direction of its length.

The reverse end of rod l-l is loosely pivoted to a lever, 15, which is pivoted to the frame and bears a fork or belt-shifter, 16. The entire reversing mechanism may be termed an automatic shifter. A polygonal or splined shaft, 17, is journaled on the frame, extending from end to end parallel with the tracks. This shaft bears a pinion, 18, provided with flanges and free to move lengthwise on the shaft 17, but not to turn independently of said shaft. The shaft 17 has also a fast pulley and a loose pulley. (Shown at 1.) and 20.) The truck 3 bears a short counter-shaft, 21, suitably supported in journal-boxes on the truck, and having a fixed pinion, 22, which engages the teeth of pinion 18, before referred to, but rests between the flanges of said pinion, so as to cause pinion 18 to move lengthwise on its shaft when the truck moves lengthwise of the tracks.

The counter-shaft 21, which must rotate with shaft 17, (by means of the intermeshin g pinions 18 and 22,) has a bevel-gear, 23, which engages al'ievel-gear, 24, on the grinder- The shaft 25 is supported in suitable journal-boxes on the truck 3, so as to be held against motion in the direction of its length, and carries the grhnling-wheel 26 and a wheel, 27, which serves to balance said grinding-wheel.

The truck 13 carries two prongs or projecting pieces, in position to engage stops 31 32 on the shifting bar 14. The stops 31 32 are held on the shifting bar by set-screws or in other convenient manner, and may be adjusted to any position 011 said bar. Then as the truck 3 is moved to engage one of the pieces with the stop 31 the bar 1 L will be moved, the belt-shifter 13 will shift belts 11 and 12, so as to reverse the movement of screw 5, and thus run back the truck, and at the same time belt-shifter 16 will shift its belt from pulley 20 to pulley 19, thus stopping or starting shaft 17, as is requisite. movement takes place when the other piece engages stop '32.

The grinding-wheel it; runs in trough 30, which carries sand, emery, or other abrading material suitable to the work. The plane or side faces of wheel 26 are made to carry this material into contact with the plate. The trough 30 is supported on legs or pillars.

A shield, 51 extends down from the front of the frame to protect the working parts from sand, the. ()ther moving parts arecovered or shielded by thin metallic plates as far as possible.

Two standards, 33) 3333, are pivoted on a rod, :34, near the foot of the frame. At the upper ends of these standards there is a rod, 35, extent'ling from one to the other. A rectangular frame or table, 3b, is pivoted to this rod, and presents a plane face or frame toward the working-face of wheel 21;. A spring, 237, at each end of the machine and bearing against the standard presses the lower edge of the frame or table so toward the grindingwheel 26, and hooks 38, pivoted to the table and engagingln-acketis $3!) on the standards, steady and support the table. Stops to, secured on these hooks by set-screws, hold the hooks in proper position with relation to the standards $323.

A shaft, i2, is journaled at each end in the standards 3 and. extends through slots it in the frame. The shaft 42 bears hevel-pinions $13, which engage a rack, ll, on the trainee. The rack l-t and pinion ii are duplicated, one rack and pinion being placed at each end of the frame.

The shaft 42 may he IUitttttl by a lever or wrench and held in any adjusted position by a clamp or other known mechanism. lhe engagement of pinions l3 with racks it will serve to keep the standards parallel with each other. The standards can thusbe swung to any angle (within their limit of move ment) around their pivots 3i, and the table 36 can be swung on pivot 35 to present its lower edge close to the wheel 20. The bars ll; 46 run lengthwise of table or frame 36 and are secured thereto by set-screws. Crossbars l7 l7 hold the ends of the glass plate, which isllltllt'ilittl at 50, Figs. 2 and 2'). The bars al may be notched and held to bars lti by screws or in other suitable manner.

The shaft 25 may he set at a very slight deviation from a right angle across the face of truck This will cause the grinding to be done at one side of the shaft, while the other side remains free from the glass plate.

The machine having been constructed as described and shown, orin equivalent manner, the glass is allixcd to the frame or table and the machine set in motion The truck 3:3 will travel lengthwise of the machine and carry Re verse l the grinder with it, the grinder or mill 26 running with its lower edge in the sandtrough 30 and having its face in contact with the lower edge of the glass at an angle thereto. The truck having traveled until it shifts the bar 14: and having ground a cut olf the surface of the glass will be reversed and move in the opposite direction until the shifting bar is again moved, when the first operation will be repeated. The springs 37 serve to hold the glass up to the wheel, but will give to prevent breakage.

\Vhat we claim is 1. In a glass-grinding machine, a track, a reciprocating truck traveling lengthwise thereof, a grinding-wheel carried by said truck, a shifter connected to said truck to reverse the movement thereof automatically, a trough beneath the grimling-wheel and extending along the path of movement thereof, and a table adjustable relatively to the grindingwhecl, all in combination, substantially as described.

a table pivoted near the upper end of these standards, springs pressing the lower end of the table away from the standards, a hookadjustalde stop arranged, substantially as described, to limit the swing of the table, and a rotating grinder in proximity to the edge of the table, all in combination, substantially as described.

4. A pair of stant'lards pivoted to the frame, a shaft carried by said standards, pinions 011 the shaft engaging racks on the frame, and a table pivoted to said standards, all combined in a glass-beveling machine, substantially as described.
