HANDLING AND LAYING GLASS.

SPECIFICATION forming part of Letters Patent No. 429,846, dated June 10, 1890.

Application filed October 16, 1889. gerial No. 327,144. (No model.)

To aZZ whom it may concern.-

Be it known that We, GEORGE H. DIOKEY and WILLIAM DUsrER,-citizei1s of the United States, residing at 'larentum, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Handling and Laying Glass; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of. reference marked thereon, which form a part of this specification.

The special object of our invention is to make an apparatus for laying plate-glass as it comes from the carrier.

The invention will first be described in c011- nection with the drawings, and then pointed out in the claims.

Figure 1 of the drawingsis a side elevation, and Fig. 2'an end elevation, with dotted lines to show the position of the bed when brought into a horizontal position. Fig. 3 is an enlarged view of the movable rolls with their mechanism, and Fig. 4 a detail view of the clamp for pulling or pushing the glass on the bed. Fig. 5 of the drawings is an elevation showing the bed-frame and connecting parts, and Fig. 6 an end elevation.

In the drawings, A represents the frame which constitutes the bed on which the plateglass is laid as it comes from the carrier.

B are plain rollers, and O felt-covered ones, the two kinds alternating on the bed. The plain rollers B are intended to receive the plates of glass when in a rough condition,

while the felt rollers 0 receive them after they have been ground and are in a finished condition.

The bed A has its lower end pivoted at a to two vertical standards a a, in order that it may be held upright between two grinding-' tables, on which it may be turned down and be laid flat. The rough glass is first placed on the bed so as to rest on the plain rolls; but after one side has been ground and finished it is made to rest on the felted rolls, which are kept clean. WVhen the bed lies flat on the grinding-table, we place a wedge under each corner in such a manner as not to interfere with the rotation of the rollers, which are turned by the frictional contact of the glass plates as they are pulled or pushed along. In order to make the felt rollers 0 support the glass, we journal them in movable bearings 0, whereby they may be raised above the plain rollers for use or carried below them when not to be used. 7

The means which we employ to move the rolls 0 vertically consist of the vertical racks D, pinions E, oscillating shaft F, and radial arms f, for turning said shaft. 0 are in the desired position they are locked by placing the latches g between the teeth of the pinions E.

The upper end of the bed A is provided with the V-shaped plates H, which are used to support the middle of the glass plate and prevent it from striking the frame before it gets down upon the rollers.

K represents pusher or puller blocks, which are fastened to endless sprocket-chains and carry the glass over the bed. They consist of the fixed right-angled jaw and the movable jaw 70, the latter being. held apart from the former by a spring I and pressed toward it by a crank-screw J. The jaw 70' works up and down on the stud k and the screw J, which has a stop or head j. There is a nutthread in the jaw 7t, which corresponds with the thread on the screw, so that the latter may hold the jaws to a tight grip upon the edge of the glass plate, the biting ends of these jaws being lined on the inside with some soft material 10 On the under side of the jaw In is a hook it, which engages a link of one of the sprocket-chains L, which are carried by the sprocket-wheels M and chains N, said wheels being fast on the shafts O. In moving the glass plates each one of the sprocketchains carries a pusher or puller K by means of the hook 70 Having had these roller-beds for laying plate glass in full operation and tried them experimentally for a considerable length of time, we have found them to greatly facilitate the handling of glass and to prevent loss by fracture or damage.

The frame A is raised or lowered by the chain 0, which Works on the sprocket-wheel P, which turns the roller 19. The chain is fastened at one end to this roller 19 and wraps around it. The chain 0 is bibranched and provided with two hooks 0 0, which engage After the rolls loops 0 0 on the frame. Thus it will be seen that the chains can be readily disengaged from the frame A.

hat we claim as new, and desire to protect 5 by Letters Patent, is-

1. The combination, with the frame A, of the alternating plain and felted rollers, the latter arranged in movable hearings to allow of their vertical adjustment, as and for the 10 purpose described.

2. The combination, with the rollers C, arranged in vertieallymovable bearings of frame A, of the racks D on said bearings, the pinions E, the crank-shafts F, and the latches I5 g, as and for the purpose set forth.

8. The combination, with the roller-frame A, of the plates H, arranged at the upper end of said frame, as and for the purpose specified.

4. The combination, with the frame A, sprocket-wheels, and sproeket-chains,of pusher or puller blocks having jaws to grasp the glass and hooks to engage the chains, as and for the purpose described.

5. A pusher or puller block K, consisting of the right-angled fixed jaw 70, having the bottom hook 70 the movable spring-retracted jaw 70, and the crank-screw J, having the stop or head j, substantially as shown and de scribed.

In testimony whereof we affix our signatures in presence of two witnesses.
