The carrier 17 is made up of the links 21 Like reference-numerals indicate like parts 22, the cylindrical antifriction-rollers 23, and in the different views. the bushing 24, extending through said links The frame of the apparatus is made up of 21 and 22 and said rollers 23 and constituting 5 the uprights 1 2 at the front of the machine the pivotal connection between the several and the uprights 3 4 at the rear thereof. The links of the carrier. The links 21 of each secuprights 1 and 3 and 2 and 4: are connected tion of the chain are located outside the links by rails 5 6, both constructed, preferably, of 22 of the adjacent section, and said links are angle-iron, with a vertical flange 7'and a horikept spaced apart by the rollers 23, which fit 5o zontal or base flange 8. The vertical flange 7 between the links The bushing 24, which I00 serves as the pivot for the adjacent sections of the carrier, is formed with flanges or heads at its opposite ends, which serve to prevent the outward movement, and consequently the separation, of the links 21 and 22. It is also formed with a central longitudinal aperture 25, through which passes the stem 26 of a glass-holder 27. The upper end of the holder 27 is cup-shaped, as shown at 28, and is adapted to receive and retain in placea tumbler29 or other article of glassware which is to be subjected to treatment in the apparatus. The lower end of the stem 26 of the glass-holder 27 is tapering, as shown at 30, and adjacent to said tapering portion 30 is a shoulder or abutment 31. It will be observed that the stem 26 of the holder 27 fits loosely in the aperture 25 of the bushing 24 and that the same is capable of vertical movement in the aperture 25 independent of the carrier.

Secured to the cross-bar 10, which connects the uprights 1 and 2 at the front of the machine, are two adjustably-mounted supports 32 for the main heater 33, the said supports being provided with elongated slots 34, through which the bolts or screws 35 pass for the purpose of securing the same to the cross-bar 10. The furnace 33 is made up of a base portion 36, a top 37, both constructed of fire-clay or other suitable refractory material, a protecting-cover 38, of metal, and a clamp 39 for retaining the parts in place. The base 36 is provided with a central opening 40, through which the tumblers 29 may beintroduced, and with an annular groove or channel 41 surrounding the opening 40. It is also provided with an aperture 42, communicating with the channel 41, for a purpose which will presently appear. The clamp 39, as above stated, is provided for the purpose of retaining the parts of the furnace or heater 33 in place and for the attachment of the same to the supports 32. The same consists of two semicircular sections 43 44, pivoted together at their ends, as shown at 45, and provided with a thumbscrew or other securing means 46 at the opposite ends of said sections for the purpose of securing the same together. The ends of the sections 43 and 44 are extended outwardly, as shown, and provided with screwthreaded openings 47 48. The section 43 is also provided with a nozzle 49, which extends into the aperture 42 in the base portion 36 of said furnace. The lower ends of the supports 32 lie against the projecting ends of the sections 43 and 44 of the clamp 39, and screws 50 extend through openings in said supports and into the threaded openings 47 and 48 for the purpose of securing the furnace 33 to said supports. Secured to the nozzle or nipple 49 is a pipe 51, having a valve 52 therein, which is controlled and operated by a valve-rod 53, having an operating-handle 54 upon its upper end. Communicating with this pipe 51 is an air-dome 55, to which a supply of air under pressure is admitted through the pipe 56, having a valve or cook 57 therein. Adjacent to the point of connection of the air-dome 55 with the pipe 51 is a supply-pipe 58 for gas or vapor fuel, having a cook or cut-01f 59 therein.

In connection with the main heater or furnace 33 I provide a preliminary heater 60 for the purpose of moderately heating the tumblers 29 on the carrier 17 before they are subjected to the high heat of the furnace 33 to prevent the danger of breaking or cracking the same. The said preliminary heater 60 consists of an elongated hood having an inner lining 61, of fire-clay or other suitable refractory material, and provided with dischargeopenings 62 in the upper side thereof. Communicating with the hood 60 at a point between the discharge-openings 62 is a branch pipe 63, which leads ofi from the gas-supply pipe 58 and is provided with a controllingvalve 64 therein. The means provided by me for elevating and rotating the glass-holders 27 separately and independently of the carrier 17 consists of a shaft 65, mounted in suitable hearings in a bracket 66 and in a hollow standard 67 and having a continuous rotary movement imparted thereto from a suitable source of power through the pulley 68 thereon. The upper end of the shaft is provided with a tapering socket 69, adapted to receive the tapering lower end 30 of the stem of the glass-holder 27, and the lower end thereof is acted upon by a lever 70, fulcrumed upon a bracket or support 71 and connected through a link 72 with a foot-lever 73. The standard 67 is slotted, as shown at 74, for the passage of the lever 70, and a coil-spring within the hollow standard 67 acts upon the shaft 65 to normally urge the same downwardly inopposition to the pressure exerted by the lever 70.

From the foregoing description it is thought that the operation of my device will be readily understood. Briefly stated, however, it is as follows: Two operators are requiredone at the rear or feed end of the machine and the otherat the front end of the machine to operate the levers 20 and 73. Glasses are placed successively in the sockets 28 of the glass-holders 27 and are removed therefrom at the same end of the machine by the same operator. The operator at the front of the machine moves the lever 20 back and forth to impart an intermittent movement to the carrier 17, and the glass-holders 27, containing the tumblers to be treated, are successively brought-to a point directly beneath the opening 40 in the base 36 of the furnace 33. As soon as a glass reaches this position the free end of the foot-lever 73 is depressed, which action, through the link 72 and lever 70, elevates the shaft 65 and brings the socket 69 on the upper end of said shaft into engagement with the tapering lower end 30 of the stem of the glass-holder 27. The said glass-holder is thereby elevated, bringing the upper edge or rim of the glass into the furnace 33 and simultaneously imparting to said glass-holder and the tumbler carried thereby rapid rotary movement. The tumbler is caused to remain within the furnace 33 long enough to melt the edges thereof and to glaze and finish the same. As the flame in the furnace 33 is caused to traverse the groove or channel 41 therein, all parts of the edge of the glass will be subjected to the same heat applied to just the point at which it is required. When a sufficient time has elapsed to glaze and finish the glass, the pressure upon the foot-lever 73 is released and the shaft and the glass-holder 27 at the upper end thereof are caused to return to their normal positions through the action of gravity and the spring which surrounds the shaft 65. Said spring 75 also serves to disconnect the upper end of the shaft 65 from the lowerend of the stem 26. Before reaching the heater 33, however, the glasses are subjected to a preliminary heating by being caused to pass beneath the hood 60, which constitutes the preliminary heater. This hood is supplied with gas or vapor fuel through the pipe 58 and the branch 63 thereof, and the products of combustion pass off through the discharge-openings 62. By this preliminary heating the danger of cracking or breaking the tumblers in the main heater or furnace 33 is overcome or at least reduced to a minimum. When the tumbler has been removed from the heater 33, the lever 20 is again operated to cause a further movement of the carrier 17 to bring the next glass-holder 27,containingatumbler29,beneath the heater 33, when the operation just described is repeated. It should be stated in this connection that by means of the air-dome 55, which receives air under compression from the airsupply pipe 56, and the gas-supply pipe 58, which enters the pipe 51 adjacent to the point of entrance of the supply of air from the dome 55, a complete and thorough mixture of air and gas is effected prior to the admission of the same to the furnace 33 and that the mixture is forced into the furnace by the blast furnished by the compressed air. The proportions of the mixture may be controlled by the valves 57 and 59 and the supply of the mixture to the furnace may be controlled by the valve 52. It should also be stated that the rails 5 and 6, which extend longitudinally of the machine and connect the uprights at the ends thereof, serve to'support and guide the flexible carrier 17 and prevent the sagging thereof. It will be observed that. the bases 8 of these rails do not extend far enough inwardly to interfere with the passage of the stems 26 of the glass-holders 27, but that the outer edges only of the lower links 21 of the carrier 17 bear upon the bases of these rails. The recesses 12 in the cross-bar 11 provide for the passage of the lower projecting ends of the stems 26 through said cross-bar.

It will be noted, further, that by the arrangement of the parts of my apparatus in which the horizontal carrier is employed, one part of which is caused to pass beneath the melting-furnace 33, the tumblers or other articles to be subjected to treatment are fed upon the carrier at one end of the machine, are caused to pass beneath the preliminary heater before entering the main heater or furnace, and are afterward caused to pass through the whole length of the machine before they are removed, thus giving time for the glasses to become thoroughly cooled before they are actually taken out of the apparatus. This is a feature of considerable importance.

In Fig. 6 of the drawings I have shown a modified form of glass-carrier in which the parallel separated links 21 and 22 and bushing 2%, connecting the same, are dispensed with and instead single links 76 77 are employed. Each of the links 76 is formed at its opposite ends with an extension 78, having an opening 79 therein, the plane of the upper surface of each of the extensions 78 being below the plane of the upper surface of the body of the link 76. The opposite ends of the links 77 are formed with downwardlyextendiug hollow studs or projections 80, which when the carrier is in its assembled position extend down through the openings 79 in the adjacent links. The stems 26 of the glass-holders 27 extend through the studs 80 and are vertically movable therein. The antifriction-rollers 23 surround the studs 80 and are held in place thereon by means of nuts or collars 81. When the parts are in place, the links 77 fit within the offset portion formed by the extensions 78, and the upper surfaces of the links 76 and 77 are practically in line with each other, as shown. The action of this form of carrier is identical with that heretofore described.
