LEER OR KlLN FOR ANNEALING GLASS.
SPECIFICATION forming part of Letters Patent No. 614,199, dated November 15, 1898. 1 Application filed December 28, 1897. Serial No. 668,874. (No model.)
T0 all whom it may concern.-
Be it known that we, ANTHONY DIXON BRO- GAN and ANDREW MURRAY MALLOOH, of the Glasgow Plate Glass Company, Firhill, in the city of Glasgow, and J AMES CRAIG, glassworker, of Abbotsford Place, Mother-well, in the county of Lanark,Scotland,have invented or Kilns for Annealing Rolled Glass, (which have been patented in Great Britain by Letters Patent dated March 16, 1897, No. 6,840,) of which the following is a specification.
This invention relates to certain improvements in leers or kilns for annealing plate and other rolled glass. The object of the invention is to provide for the annealing in any given time and with less risk of breakage of a larger quantity of glass than it is possible to anneal in leers heretofore devised.
Our apparatus is designed for annealing all kinds of rolled glass, including figured an cathedral glass.
In the drawings, Figure 1 is a side view of the apparatus in the kiln, the front side of the kiln being broken away. Fig. 2 is a crosssection of the kiln when empty on line 2 2 of Fig. 1. Fig. 3 is a plan view of a glass-car: rying frame. Fig. 4: is a partial sectional view on a longitudinal vertical plane passing between two of the rails a Fig. 5 is a side View of a portion of the lifting device. 6 is a side View, partly in section, of a modification. Fig. 7 is a side view, partly in section, of-one form of raising and moving devices; and Fig. 8 is a section on line 8 8 of Fig. 7. t.
A is a leer or kiln having a transverse track or way E, on which the truck or bogie D can be run into and from the kiln through a suitable opening (not shown) in the kiln-wall.
O are frames each designed to carry one or more glass plates. Frames '0 have front wheels 0 and rear wheels 0, adapted to support the frames .0 on the truck D and to roll the frames from the truck, as hereinafter described. The forward wheels 0 are supported outside the ends of the frames on brackets 0 whereby said wheels are in position to travel on the ledges a at each side of the kiln.
Fig.
F is an incline leading from near the edge of way E to the top of ledge a, and (1 is a similar incline extending downward at the opposite or outlet end of the kiln, where is a truck or bogie D on a suitable track and adapted to receive frames 0 as they are delivered from the kiln. The forward end of frames 0 may be provided with one or more wheels 0 carried by arms 0 intermediate wheels 0, angle-iron or other rails 0. being supported from the roof of the kiln by bolts or hangers a in position to be engaged by said wheels 0 These intermediate wheels are only necessary when frames 0 are wide.
a are grooves or rails for wheels 0, and asimilar intermediate grooves or rails for intermediate wheels on the same shaft as wheels 0'.
, c is the rear end of the frame. When frame 0 is in inclined position, 0 serves as a stop for the glass plate on the frame, preventing the plate from sliding down.
I is a wire rope adapted to be drawn in the direction of the arrow, Fig. 1, by hand or by suitable power (not shown) and when released to move backward under the influence of weight J in inclined tube or casing K, which is supported by the top of the kiln. To the weightJ is secured a rod L, (see Figs. 1 and 5,) having a hook at its lower end, adapted to engage a hook C at the forward end of frame 0.
Fig. 6 shows a modification in which rod L projects from weight J at right angles to the cable instead of parallel therewith, and the tube is supported by the top A at K K H H are slow-niovin g pulleys, around which extends endless chain G, which chain has projections G or similar devices for engaging frames 0 as the latter are raised to inclined position and to carry the same along.
B is a track or way for returning empty frames 0 after having been relieved of annealed plates, to be used again at E.
In using the apparatus frames 0 are carried singly uponbogie D, which is run into the kiln so as to bring frame 0 in line with track a. A plate of glass as it comes from the casting-table is pushed through an opening 0 in the kiln-wall, and as it stifiens is pushed onto the frame 0 and the frames caught by the lifting gear or device, which draws the forward end of frame 0 up inclines F to ledges a, when the frame is caught by a tooth G and carried slowly forward. As soon as the first frame 0 is raised another frame is run into position and another plate inserted.
'lVhen the frames reach the outlet end of the kiln, they travel down incline a and run onto bogie D' and are removed and the frames are taken to the starting-point to be again used.
By the apparatus described the glass plates are easily handled, and owing to the position of the frames in the kiln great economy of space is effected.
The annealing-chamber is preferably rectangular in cross-section and of less height than the length of frames 0.
We claim 1. An apparatus for annealing glass consisting of a leer or kiln having a long annealing-chamber, frames for supporting plates of glass, means for holding said frames in the annealing-chamber in inclined positions and parallel with each other, and means for moving the inclined frames through the kilnchamber.
2. An apparatus for annealing glass consisting of a leer or kiln having along annealing-chamber, frames for supporting plates of glass, said frames having front wheels 0, tracks at opposite sides of the kiln having upward inclines F, horizontal parts a, and downward inclines a said wheels 0 traveling on said tracks, the bodies of the frames being adapted to move between said tracks in inclined positions.
3. The combination with a leer or kiln having a long annealing-chamber, a track near the top of the kiln, and a second track at the bottom of the kiln narrower than the upper track and between the rails of the upper track, of a glass-plate-carrying frame having front wheels outside the ends of the frame in position to travel on said upper track and having rear wheels nearer together and running on the low narrow track, as set forth.
4. The combination with a leer or kiln having an annealingchamber, elevated side tracks a, and low intermediate tracks a of a glass-plate-carrying frame having front wheels adapted to travel on the elevated tracks, and rear wheels adapted to travel on the low intermediate tracks thereby holding the frames in inclined position.
5. The combination with a leer or kiln having an annealing-chamber, an elevated track a therein, and frames 0 having front wheels 0 adapted to travel thereon, of a lifting device consisting of an arm adapted to engage frames 0, aweightJ carrying said arm, a tube K in which the weight can move, and means for raising said weight and parts connected thereto.
6. In a leer or kiln having an annealingchamber the combination of an inclined tube supported at the top of said chamber, a weight in the tube adapted to move up and down therein, an arm moving with the weight and projecting from the tube, means for raising the weight, elevated tracks in the kiln, a glass-carrying frame, a hook adapted to engage said frame and connected to said weight, as set forth.
7. In a leer or kiln having an annealingchamber and glass-carrying frames 0, the combination of an inclined tube supported at the top of said chamber, a weight in the tube adapted to move up and down therein, an arm moving with the weight projecting from the tube, and adapted to engage frames 0, and a cable connected to the weight for raising it and said frames, as set forth.
8. In a leer or kiln having an annealingchamber and glass-carrying frames 0, the combination of an inclined tube supported at the top of said chamber, a weight in the tube adapted to move up and down therein, an arm moving with the weight projecting from the tube, and adapted to engage frames C, a cable connected to the weight for raising it and said frames, and means for slowly moving said frames longitudinally through the kiln.
9. In a leer or annealing-kiln, a long annealing-chamber of approximately rectangular section provided with rails or ledges in proximity to its roof, in combination with a plurality of glass-carrying frames adapted to be supported on said rails or ledges, and means for slowly traversing the series of frames throughout the length of the kiln.
10. A leer or kiln having a long chamber A, an elevated track a, frames 0, combined with means for drawing the forward end of the frames onto said elevated track, and a traveling endless chain lengthwise of the chamber and having means adapted to engage and move said frames.
11. The combination of an annealing-chamber, a track near the top thereof, pulleys H, H, chain G one side of which travels in the top of the chamber, said chain having hooks G", and inclined glass-carrying frames engaged by said hooks.
