GLASS-ANNEALING LEER.

SPECIFICATION formingpart of Letters Patent No. 270,929, dated January 23, 1883.

Application filed November 16,1882. (No model.)

To all whom "it may concern.-

Be it known that we, OHARLEs W. BROCKU- NIER, of Bridgeport, county of Belmont, State of Ohio, and DANIEL O. RIPLEY, of-Pittsburg, county of Allegheny, State of Pennsylvania, and citizens of the United States, have invented or discovered a new and useful Improvement in Glass-Annealing Leer; and we do hereby declare the following to be a full, clear, concise, and exact description thereof, reference being bad to the accompanying drawings, makinga part of this specification, in which-like letters indicating like parts- Figure 1, Sheet 1, shows a front end eleva- Fig. 2 is a similar view ofthe rear end and Fig. 3, Sheet 2, shows a longitudinal vertical section taken in the plane of the line 00 00, Fig. 2.

Our invention relates to certain improvements in leers or furnaces for annealing glassware; and it consists in the construction of leers in vertical pairs, one leer being above the other, with means for approach to the separateleers at the front for insertion of ware, and also at the rear fondrawing the trays and removing the ware, as hereinafter more fully described and claimed.

In the drawings, A A and B B represent two pairs or sets of annealing-chambers, the

chambers in each setbeing separate, but built one directly over theother. They may be of the usual or an v desired form-say about five feet wide and fifty feet long, more or less.

. Furnaces D, of the usual construction, are built alongside of each annealing-chamber at. the front, as represented in Fig. 1. Each furnace opens into its ad acent annealing-chamber under theskew of its arch, as at cl, Fig. 3,

and the products ofcombustion pass backward to or somewhat beyond the center, and escape through suitable flues, h, into the stack H.

Along the floor of each chamber are trays or pans 0, which are connected together in line by books 0, and may be mounted on slides or rollers in the usual or' any convenient way.

- These trays are designed to hold the glassware.

'They are moved along the bed or floor from the front, Fig. 1, where the ware is inserted, to the rear, Fig. 2, where it is removed. As successive trays are emptied at the rear they are disengaged by unhookin'g at c, and are carried around to the front, connected, and again passed into the annealing-chamber through the openings d, which are made in the leer-front D in line with the bed or floor on which the trays move, and of proper size to admit the trays without unnecessary open space; also, in the leer-fronts D, above the openings cl, are made doors E, by preference in two or more hinged parts, through which the ware to be treated is passed into the chambers. By opening the whole or a part of such doors, openings may be made of proper size to admit large or small pieces, as maybe desired. This work of putting the glass pieces into the annealing-chambers is usually-performed by boys, who uselonghandled forks. The doors E are placed at the side of the chambers, or rather the door above is at one side of its chamber and the one below is at the opposite side of its chamber; and in the two sets'of leers the two upper doors for chambers. A B meat the adjacent sides and the two lower for chambers A B are at opposite sides. In order to make any and all these doors easily accessible, a bridge or elevated floor, F, is made in front, below the two upper doors and between the two lower ones, such bridge having an ascending incline,f, leading to the same from the main house-floor F. \Vhen charging the upper chambers the boys stand on this bridge,and are then in convenient position to reach either upper door. In charging the lower chambers'the boys stand on the main floor F, at either side of the bridge.

In order to reach all parts of the tray easily, so as to distribute the ware uniformly over the same, laterally-extended openings 0 are made at or near the level of the trays, leading from the door-openings E toward the opposite side of the chamber. The article can thus be passed into the chamber through its door, whether above or below, and then be set upon any desired part of the tray by passing the handle of the fork sidewise into the opening 0.

The iron frames 0, surrounding the doors E and openings 0, may be made of any suitable form and construction adapted to support the doors and the brick-work above, which latter, as well as the arches or caps D may be carried to any desired height above the leers proper, to arrest passage of heat from the top of the leers forward into thehouse.

One special feature of advantage resulting from these features of construction in the leerfront is economy of space required for charging, four leers being charged without occupying any more house space than has heretofore been required for the manipulation of two leers. The same features of advantage are also secured at the rear of the furnace by building the leers in vertical pairs, or one above the other. At this end (see Figs. 2 and 3) is also shown new andimproved mechanism for drawing the trays through and out of the annealing chambers. This mechanism is constructed as follows Rods N, in any desired number, are secured in vertical position on either side of the chambers, the foot being secured in sockets or rests a on the floor, and the upper end by brackets N, which are fastened to the furnace-walls in any convenient way. A horizontal shaft, It, is mounted on these rods by connections It, one part, 1*, of which forms journal-bearin gs for the shaft, while collars 'r thereon encircle and slide upon the rods, thus permitting vertical movement of the shaft. The shaft is balanced, and thus held in the desired vertical position, by counter-weights T, which are connected thereto by wire or other cords, T, whfch latter pass over sheaves T overhead. Three such weights are shown; but this number may be varied as desired. Thus balanced, the shaft may be moved upward against the collars n, or other suitable stops, in proper position for drawing the trays in the upper chambers, '(see Fig. 3;) or it may he moved down upon the rests a (see Fig.2) in position for the lower chambers. The trays are drawn by means of sprocket-wheels s, keyed on the shaft, and chains 8, one end of the latter being hooked to-the adjacent pan, as at c, and the other end placed upon or in engagement with the sprocket-wheel s, as illustrated in Fig. 3. Continuous rotary motion is given the shaft by chain and pulley S S, which make connection with any suitable. drivingpower; also, any well-known form of shifting mechanism may be employed for putting the shaft It in and out of driving connection or gear, which may be operated by a lever within convenient reach of the workman at the rear of the leers. As the trays are drawn out of the chambers they are supported on projecting brackets 2 which are secured to the leer-walls in any convenient way. In order to bring these brackets. at convenient heights, so that the ware may be removed conveniently both from the upper and lower trays,the floors of the upper chambers, A B, are inclined downward toward the rear, and the floors of the lower chambers, A B, are inclined upward in the same direction, thereby bringing the floors nearer together at the rear than at the front, where greater depth of chambersis required for flue-openings d and proper combustion of gases and development of heat in the front half of the chambers.

Several important advantages are secured by theimprovements herein described-for example, cheapness in construction, one foundation serving for two leers, and the front and dividing wall between the two being common to both. Heat is saved, as a considerable part of that which has heretofore escaped from the walls is now utilized in heating the companion leer, and with the four leers constructed as herein described the house will be heated but little, if any,more than with two of the old I construction. Space required by the workmen in operating the leers will be economized as hereinbefore described, and also the space occupied by theleers, as four leers constructed as described will occupy no more floor-space than two as heretofore built. This alone is a very important advantage, especially in city houses, and the features of construction by which these advantages are secured are valuable improvements in this class of furnaces.

If desired, for local or other reasons, some of these improvements maybe employed without employing all; also, various modifications may be introduced without departing from our invention. For example, a different form of approach may be made to the upper leers at the front, or the floors of the chambers may be made parallel instead of converging backward, other features of our invention being used; also, two shafts, B, may be used, instead of one movable one, the two being fixed in position, and one or more such shafts, with sprocket-wheels, chains, and driving mechanism, maybe combined with a singleleer chamber and its trays for drawing the latter with good results; but for cheapness in construction and convenience in manipulation we prefer the construction shown and described.

We claim herein as our invention- 1. The combination of two leers, built of the same length one upon the other, with separate openings in their common front for charging ware into the two leer-chambers, and also in the rear end for removing the ware therefrom, substantially as set forth.

2. The combination of two leers, built one above the other, such leers having inclined floors converging toward the rear, substantially as set forth.

3. Two leers, built one upon the other, ha v ingdoors for charging the leer-chambers in the front, on opposite sides, in combination with a bridge or raised floor below the upper door and at one side of the lower door, substantially as set forth.

4:. In combination with the annealing-chamher and trays of aleer, a door in the leer-front opening into the chamber above the trays, such door having a laterally extended opening leading therefrom in or near the plane of the trays, substantially as and for the purposes set forth.

5. The combination of four leers, built in vertical pairs side by-side, the upper leers havin g charging-doors on the adjacent sides, and the two lower leers having charging-doors on the remote sides,of the leer-chambers, with an elevated bridge below the upper and between the lower doors, substantially as set forth.

6. In combination with a leer-chamber, arotary shaft, R, mounted at the rear of the 5 chamber, sprocket-wheel 8, chain 8, trays G,

and power mechanism for giving the shaft rotary motion, substantially as set forth.

7. Two leer-chambers, built one above the other, in combination with trays 0, vertical 1o rods N, transverse shaft R, movably mounted on such rods, counter-weights T, sprocket- 7 wheels 8, and.chains s, substantially as set forth.

In testimony whereof we have hereunto set our hands.
