' ST VIRGINIA- 1 EVELING MACHINE Application filed December 17, 1928; Serial no. 336,668.

This invention aims to provide a simple but very efficient machine whereby the edges of plates of glass, or other material, may be beveled. The invention aims to provide novel means for beveling off the edges of the glass, and to provide novel means for moving the glass with respect to the beveling instrumentalities.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to Which the invention appertains.

With the above and other objects in View, which Will appear as the description pro- 15 ceeds, the invention resides in the combination and arrangement ofparts and 1n the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made Without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention;

Figure 2 is a transverse section of the complete' machine; Figure 3 is a deta-il showing one of the 3;, hearings. V

In carrying out the invention, there i vided a support which, as a, whole, i nated by the numeral 1. The support 1 pref:

I erably includes an elongated main frame 2 in the side of which is located an auxiliary frame 3 which, preferably, is somewhat lowor than the main frame 2, as Figure 2 will show. An elongated bed 4 is secured to the 7 main frame 2 and has a recess 5 at its top.

40 V A carriage 6 is mounted to reciprocate on the bed 4, and is provided with depending v ribs 7 that are received for sliding movement in grooves 8 formed in the upper surface of 7 the bed 4,the ribs and the grooves holding 45 the carriage don-the bed 4: for "right sliding movement. A table'9 isheld onthe carriage 6 forverticai ayustment by means of screws 10 threaded into the carriage 6 a H extended downwardly into the recess 5 of t e;

,bedt. The iece ofla'ss oriother mate a gear 15, or th'e lil-ze, the constructionbeing such that the shaft maybe rotated eith-er'bv through the medium of the gear 15. V 'Theshaft 12 extends into therecess 5 in the bed 4, andapinion 16 is secured totheinner end of theshaft-12f The pinion" 16 meshes with a rack 17 .securedto the bottomof the carriagefi andlocated intherecess 5.

Posts '18 are secured to the bed 4 and em; tend upwardly with'respect to the bed. Bearscrews20 that are held in place by lock nuts 21. .In the bearings 19 of the respective posts 18. arejournaled shafts 22, 23, and 24, there being a set of these at each side of the mach1ne,.as Wlll be understoodwhen Figure 2 1scompared with Figure 1. On the inner ends of the shafts .22, .23, and 24, grinding wheels 25 are SGC1116d,-tl16j wheels being so shaped that they will bevel theedge of the plate 11 of glass,as shown at .26, when the carriage (Sis moved-with respect to thevvheels.

Any suitable means maybe providedfor operatingthe machine. Inthe present em bodiment ofthejinvention but not of-necessity, an electric motor 27 is mounted on the auxiliary framed On the shaft of the motor Jed 7 nected by belts 32 with pulleys 33 on the shaft Q 24. The shaft 30 carries pulleys 34 engaged by belts 35 extended around pulleys 36 on the shaft 22, and around pulleys 37 on the shaft 23. Idlers 38 are supported for rotation, as shown at 39, on the bed 4 and serve to hold down the belts 35 on the pulleys 37.

In practical operation, the piece of glass 11 which is to be beveled is placed on the table 9 and, if necessary, secured thereto. By manipulating the screws 10, the operator can level up the table 9 so that the plate 11 of glass will travel properly with respect to the grinding wheels 25. The shaft 12 is rotated, ether by means of the hand Wheel 14 or by means of the power wheel 15, and the pinion 16 on the shaft 12 cooperating with the rack 17 on the carriage 6 will cause the carriage to move-with respect to the grinding wheels 25, and since the the grinding wheels are rotated rapidly, the edges of the plate of glass will be bevelled off as shown at 26. The grinding wheels 25 are carried by the shafts 22, 23, and 24, and can be adjusted vertically by means of the bearings 19 shown in Figure 3.

When the motor 27 is in operation, the pinion 28 drives the pinion 29 and rotation is imparted to the shaft 30. From the shaft 30, rotation is imparted to the shafts 24: and their grinding wheels 25 by means of the pulleys 31, the belts 32, and the pulleys 33. From the shaft 30, rotation is imparted to the shafts 22 and 23 by means of the pulleys 34, the belts 35,

and inexpensive to manufacture. It will be found thoroughly effective for the ends in view.

What is claimed is:

In a glass-grinding machine, a bed provi-ded in its upper surface with a longitudinal ciprocation to the carriage, the means for raising, leveling and lowering the table being spaced to clear said means, as the caris reciprocated, terminal grinders and an intermediate grinder supported for ro tation in operative relation to the'c'arriage, the terminal grinders being spaced from the intermediate grinder by a distance less than the length of the work on the carriage, and

The machine is simple in operation, strong,
