CASTING-TABLE.

Specification of Letters Patent.

Patented July, 25, 1911.

Application filed November 29, 1910. .Serial No. 594,800.

the United States of America, residing` at e Charleroi, in the county of Vvrashington and State of Pennsylvania, have invented certain new and useful Improvements in Casting-Tables, of which the following is a specification, reference being had therein to the accompanying drawing.

This inventionrelates to a casting table especially designed for the manufacture of sheet or plate window glass, and the primary object of our invention is to provide a novel tiltable table upon which plate glass can be expeditiously and economically produced.

Another object. ofthe invention-is to obviatc the necessity of manufacturing large sheets or plates of glass by first producing a cylinder',*capping and splitting the same.

A further object of the invention is to furnish a casting table with positive and reliable means in `a manner as will be hereinafter set forth for equally distributing and pressing molten glass upon the casting table,

whereby the sheet or plate of glass produced4 can be tilted for annealing` purposes with smooth and uninterrupted surfaces. i

A still fu er object of the invention is to provide a casting table consisting of comparatively few parts compactly assembled and easily manufactured.

A still further object of the invention is to accomplish the above results by a ma-A chine that is simple in construction, durable, inexpensive to manufacture and efficient for producing` sheets or plates of glass.

With the above and such other objects in view las may hereinafter appear, the invention consists -of the novel construction, combination and arrangement of parts to be hereinafter specifically describedl and then claimed.

Reference will now be had to the draw ings forming part of this specification, wherein like numerals of reference designate corresponding parts, in which .Figure 1 is a side elevation of the machine, Fig. 2 is arear elevation of the same, Fig. 3 is a longitudinal sectional view of the table, Fig. 4 is a plan of the same, Fig. 5 is a perspective view of a detached guide, and Fig. 6 is a perspective view of a detached starting or loosening device adapted to form part of the table.

The reference numerals 1 denote base plates mounted upon a suitable foundation and supporting standards 9. and 3 having the upper ends thereof provided with bearings 4 for a revoluble shaft 5. Revolubly mounted upon the shaft 5 are a winding drum (3, ahois'ting drum 7 and a drum 8 to which is secured one end of a cable 9 which is wound upon the -drum 8` and. provided with a counter-balance weight 10.

11 denotes bearings carried `by the rear' sides of the standards 2 and 3 for a revoluble shaft 12 ,having one end thereof provided with a crank 13. Mounted 'upon the shaft 1'2 is a drum 14 to which is attached one end of a cable 15, said cable being wound upon the drums 14 and 6 with the other end "of the cable attached to the drum 6.

1G denotes a shaft journaled in the standards and 3 adjacent to the bearings 11 and mounted upon saidl shaft between'said bearings are supports 17 for a presser block 18,-said supports being secured to the upper side of the block 18 by set screws 19 or other adjusting means. The' outer end of the block 18 is provided with an adjustable transverse knife 20 adjusted' through the medium of set screws 21. .Attached to the outer end of the `block 1S through the medium of an eye-bolt Q9. is one end of a cable 23 having the opposite end'thereof wound upon and secured to the drum 7.

Z4 denotes oppositely disposed pedestals located adjacent to the standards 2 and 3 and mounted upon the upper ends of said pedestals are bearings 25 in which is joury naled a shaft 26. Mounted upon the shaft 2G between the pedestals 24 are the de' pivotally connected to said bearing by a curved link 3Q is the outer end of a crank 33 mounted upon a rock shaft 34 supported by the standards 2. and 3 contiguous to the lower ends thereof. -Mounted upon the end of the shaft34 adjacent to the standard 2 is an singularly disposed arm and fixed upon the upper end of said arm is a weight 38 adapted to facilitate the moving; and holding of the table either in a horizontal or tilted position.

37 denotes two angle guides pi-votally mounted by pins idupon the table 28 at the rear end thereof and adjacent to the lon-gr tudinal edges of said table, The lateral franges of the guides 37 are extended at the forward ends of lsaid guides, as at 39 -and provided with angularly disposed slots d0, Extending upwardly through theV slots d() are the crank pins il of a rock shaft li2 journaled in depending bearings 4:3, carried by 'the under side ofthe table adjacent to the forward end thereof. y @ne end of the rock shaft l2 has crank or suitable handle dt whereby it can be easily rocked toshift the angle guides 87 upon the table 28.

fit-5 denotes an angie bar arranged transversely of the table at the rear'end thereof, said bar having the lateral flange 46 thereof slotted?, t? and prt vided with rearwardly extending apertnred lugs (t8. The angle bar d5 is retained upon the rear end of the table by guide pins orbolts i9 extending through the slots l? into the table 28. i?iv ly mounted between. the apertured lugs ay a pin 50 is an arm 51 fulcrunled7 as at between depending bearings 587 carried 1e rear end of the table. The lower end ythe arm 51 is pivotally connected, as at to a rod 55 and said rod is pivotally cond, as at 58 to an or rating lever 5f y' 'mounted in a bearing 58 arranged a po nt in the of the standards 2 and 3 and in alineinent with the longitudinal axis of the table. The elements l5 to 58 inclusive constitute a starting or loosening device that. will be hereinafter referred to.

fA notes rails arranged between the s 2d and constituting i. ear or truck 60 having a slab 6l adapted to receive a plate or sheet of glass from the table 28, the car or truck 60 being arranged wheini:'Yr it be easily shifted into an annealing oven or furnace 62. Located at the sides of the track are' supports 63 for a transverse inclined chute 84, said chute having the lower edge thereof in proximity to the slab 6i of the car er truck 60 and the upper edge thereof positioned whereby' when the table 28 tilted, the surface of said table will be in a plane with the surface of the chute 6d, thereby allowing the sheet or plate of glass upon the table to slide by gravity over the chute on to the slab B1 with out becoming distorted or injured.

In operation, it is necessarythat the at? tendant of the machine shift the' angle guides inwardly, correctly position the transverse angle bar 4:5, have the table 28 in horizontal position, the presser block 18 in an velevated position, and the car or truck 60 track: for a essere in position with Ythe forward edge ofthe slab Gl.' adjacent to the lower edge of the chute Gil. rThe molten Lglass can then be poured upon the table 28 and the shaft l2 rotated to lower the presser block 18 upon the molten glass, whereby it will be evenly distributed upon the table and pressed by the weight of the bloclr to that extent as to forni a sheet of tglass having a lower and upper smooth surface. "When the block 18 is lowered7 the knife 2O thereof severs the forward edge of the plastic sheet or plate and limits the downward movement of the block 18, consequently by adjusting' .the knife 20 and the set screws 19, the thickness of the sheet or plate'of glass upon the table 28 can be regulated. The pressure of the block 18 upon the glass causes the glass to congeal and produce a plastic sheet or plate. The attendant of the machine then rocks the shaft 4t2 and through the medium of the crank pins il shifts the forward ends of the guide bars 37 outwardly, thereby releasing"v the longitudinal edges of the plastic sheet or plate. The attendant can then elevate the block 18 and tilt the table 28 and by operatingl the lever 57, the transverse angle bar 49 will be shifted sufficiently to loosen and start the plastic sheet or plate upon the table 28, whereby it will slide over the chute 64 on to the slab 6i. of the car or truck 60, said car or truck being moved forward toward theannealing oven as the plate or sheet passes on to thev slab (il. After the plastic sheet or plate of Xglass has left the table 28, said table can be restored to its normal position) for another' casting of glass.

Frein the foregoing it will be observed that. We have devised a tiltable casting table in connection with which certain devices are employed for insuring a high degree of perfection7 besides expediting the product-ion of sheet or plates of glass, and while in the drawings there is illustrated a preferred embodiment of the invention, it is to be understood that the structural elementsthereof are susceptible to such changes as fall within the scope of the appended claims.
