II to support the rounded edges of the glass sheets the es do are slotted es i udiceted set M to so Iva receive the pivot 42 upon which the roll 36 is mounted so that the arms may be adjusted and clamped in position by a nut 43 carried upon the pivot. The arms 34 act to brace the bracket 26 in the position to which it is adjusted.

Projecting from the end portions 44 of the arms is a series or fingers 45 arranged so that each plate of. glass lies between two of such fingers. The ends of these fingers are provided with rubber caps 46 and the fingers serve to steady the plates and hold them in position as they move up and down along the

rollers

28, 28 and 30. similarly, another set or fingers 41 are provided at the lower edges of the sheets, such fingers being secured to the pusher members I I and serving to properly space and guide the glass sheets at their lower edges. Mounted on the pusher ll and extending thereirom in the same direction as the arms 3!, is a third series of fingers "a. The fingers "a serve to steady the lower portion of the glass sheets adjacent the edges guided by the roller 31. In order to press the-glass sheets downwardly and give them the necessary grinding pressure upon the wheels, shot bags 48 are placed upon the sets of sheets, as indicated in Fig. 1. Any other suitable means for applying downward Dressln-e to the sheets may be employed and this pressure may be adjusted to suit requirements.

Fig. 1 illustrates the apparatus adiusted to grind thelower edges of the glass sheets and the rounded corners joining such edges and one of the side edges of each sheet. By a proper adjustment of the runway rollers H, and of the guide brackets 28, each sheet is given the grinding contact necessary to round the portion of the sheet referred to. As the sheet approaches the first wheel, the portion A (Fig. 3) is engaged by the wheel. .As the sheet is carried still further forward, the wheel contacts with the rounded portion B of the sheet, and finally as the sheet rides on of the grinding wheel in its movement to the left, the wheel contacts with the portion C of the sheet. In this manner, the grinding of a straight surface and a curved surface is accomplished in the one operation, and during the movement of each'sheet over the wheels, it moves freely in its guide rollers upon the brackets 28 and accommodates itself to the surface of the wheel. a

Fig. 5 illustrates the adjustment of the apparatus in grinding body lights 49 having the curved surfaces 50. In this instance, the runway is positioned somewhat difierently and the brackets 25 instead of being at an angle to the vertical, as is the case in the adjustment of Fig. 1, are placed in a vertical position, so that the glass sheets Id in their movement over the grinding wheels move in a right line vertically instead of v at an angle to the vertical.

Fig. 6 illustrates the adjustment of the apparatus employed in grinding body lights having a straight'edge Ii and the

rounded corners

52, 53. In this instance, the rolls H of the runway sections are adjusted at the angle shown and the brackets 26 occupy the position shown in the figure. .As a sheet approaches a wheel, its corner 52 engages the wheel and is ground, after which the straight edge 5| passes over the wheel, and as the plate descends in its movement away from the wheel, the corner It is ground. It is thus possible to grind straight or curved edges or practically any combination of the two,
