APPARATUS FOR SEVERIN@ ARTICLES OF GLASSVVARE.

SPECIFICATION forming part of Letters Patent No. 67' 6,698, dated June 18, 1901.

Application filed January 2, 1901. Serial No, ltll. (No model.)

upon a blown article of glassware may he quickly, safely, and effectively removed in a simple and economical manner.

A further object of the invention is to provide means whereby a machine comprising a plurality of revolving burners requiring l but one operator may be converted into one comprising a plurality of separately-rotatable burners requiring the services of a number of operators.

A further object of the invention is to provide means whereby the cracked-off nib or projection on the glassware may be stripped off the upper end thereof and removed to a receptacle for containing the same.

A further object of the invention is to provide means whereby the glass article may he automatically discharged from the burner after its nib or projection has been cracked oif and delivered upon a carrier for conveying the same from the machine.

Other objects and advantages ofthe invention will hereinafter appear, and the novel features thereof will be set forth in the claims.

In the drawings forniinga part of this specification, Figure 1 is a plan view of my improved apparatus. Fig. 2 is a sectional elevation of the same, and Fig. 3 is a similar View showing the apparatus in its converted form.

Like reference-numerals indicate like in the different views.

In carrying out my invention I employ a rotatable burner-supporting frame 1, having a series of radially-extending arms 2 secured thereto, which arms are provided with vertically-disposed tubular extensions 3, each carrying a burner-support 4, in which is mounted an annular burner 5. The frame parts 1 is provided at its Vcenter with what may he termed a hub 6, having a tapering opening therethrough which receives the central stationary support 7, having tapering or coneshaped walls, which are ground to i'it the inner walls of the opening through said hub. The support 7 serves as a bearing, on which the frame 1 is mounted to turn, the same heilig secured to the uprights 8. Extending through the support 7 and having hearings therein and also in a bearing-plate 9 is a central vertically-disposed shaft 10. Surrounding the shaft 10 is a hollow sleeve 11, constituting the drive-shaft of the apparatus and having thereon a pulley 12, through which power may he supplied from any suitable source. The said sleeve 11 is provided with a boss 13, through which extends a set-screw 14:, said set-screw being provided for the purpose of coupling and uncoupling the sleeve 11 and the shaft 10. To the sleeve 11 is secured the gear 15, which meshes with an intermediary gear 16, which intermediary gear in turn meshes with the teeth 17 of an internal rack on the frame 1. By this means the motion ofthe sleeve 11 may he transmitted to the burnersupporting frame 1 for the purpose of rotating the latter around its central support or bearing 7. In order to provide means for throwing out of gear the connection between the sleeve 11 and the frame 1, I mount the intermediary i gear 16 upon an elongated stud 18, secured to and extending downwardly from the support 7 and having a shoulder or nut 19 upon its lower end. rlhe gear 16 is held in its raised position in mesh with the gear 15 and the teeth 17 by means of an adjustable collar 20, mounted on the stud 18 and locked therewith by means of a set-screw 21. When it is desired to throw the gear 16 out of mesh with the gear 15 and the teeth 17, it is merely necessary to loosen the set-screw 21 and force the collar 2O and the gear 16 downwardly or allow these parts to fall hy gravity.

In the outer surface of the support 7 is formed an annular groove or channel 22, the same lying in a horizontal plane and having communicating with it the ducts 23 24. An air-supply pipe 25 communicates with the duct 23, and a gas-supply pipe 26 communicates with the duct 24. Air and gas may thus he admitted to the groove or channel 22 and be there mixed prior to the feeding of the IOO ' same to the burners.

Of course, if desired, the air and gas may be mixed prior to their introduction into the channel 22. In this event one of the ducts 23 24 and the pipe communicating therewith may be dispensed with. In each of the arms 2 of the burnersupporting frame 1 is a duct or passage 27, communicating with the groove or channel 22 in the support 7 at one end and with an annular groove or channel 28 in the extension 3 at the other end. Inl each of the burnersupports 4 are openings 29 in the same plane with the groove or channel 28 in the extension 3, with which connects one end ofapipe 30, whose other end communicates with the annular burner 5. Through the passage 27, vthe groove or channel 28, and the pipe orpipes 30 gaseous fuel is conveyed from the channel or groove 22 in the support 7 to each of the burners 5. As heretofore stated, the burners 5 are annular, and each of the same may be made up of one or more parts, as may be desired. An annulardischarge-orifice 3l, however, at the center of each of the annular burners is provided, through which a thin annular inwardly-extending jet of ame projects. As the burners 5 are mounted on the burner-supports 4, the same are stationary or movable, according as the supports 4 are stationary or movable. Beneath the burner 5 is an annular sheet 32, of asbestos, mineral wool, or other like material, and the inner walls of the burner-supports 4, as well as of the hollow extensions 3, are lined with asbestos, mineral wool, orthe like, as shown at 33, this lining being for an obvious purpose. Each of the burner-supports 4 isprovided with the cog-teeth 34, which mesh with a driving-cog 35, secured to the central shaft 10, heretofore referred to.

Within the hollow burner-support 4' is a glass-holder 36, the same having a stem 37 thereon adjustably mounted in the bracket 38, by means ot' which the glass article 39 to be subjected to the action of the jet of flame lfrom the burner 5 may be properly supported and adjusted. The bracket 38 has an arm 40 thereon which projects out through a boss 4l on the side of the burner-support 4 and has a roller 42 on its outer end. The bracket 38 `is normally held inwardly at the center of the burner-support 4 by means of a spring 43, secured'at its ends to the arm 40 and the vboss 4l, respectively. The inward movement of said arm 40 and of the bracket 38 thereon is limited by a collar 44 on said arm, which is adapted to engage the outer end of the boss 41. The roller 42 extends downwardly from the arm A40 and during the rotation of the burner-supporting frame l is adapted to engage a stationary cam 45, secured to the post or upright 46 and lying Within the path of movement of each of the rollers 42 pertaining to the different burners. Then the roller 42 comes into engagement with the cam 45 during the rotation of the frame l, the arm 4l is drawn outwardly against the action of the evees through the lower end of the tubular extension 3, as will be apparent. When the glasses are thus caused to drop, they fall upon a carrier 47, by means of. which they are conveyed away from the apparatus to a grinding-machine, where the next operation thereon is to be performed.

lVhen the glass articles 39 drop from the machine, some provision must be made for removing the cracked-off nibs or projections. To do this, I employ a stripper 48, consisting of two substantially parallel curved arms whose outer ends are flared and the space between which is located directly overthe path of movement of the glass articles 39, carried by the holders 36. During the revolution of the burners, therefore, upon the central Support or bearing 7 the nibs at the outer ends of the glass articles 39 are caused to pass between the stripper-fingers and be held and supported thereby, an engagement being had with said nibs or projections through the beads or flanges which are formed thereon. The inner ends of the stripper-fingers are secured'to a pan or receptacle 49, which is suspended from a point directly above the shaft l0 and is located just above the driving-gear 35 within the space between the burner-supports 4. The lower end of the pan or receptacle 49 has a socket 50 therein, which receives the upper projecting end of the shaft l0. In this way lateral displacement of the pan or receptacle 49 is prevented. As the nibs or projections from the glass articles 39 are successively removed they are forced along in the guideway formed by the stripperfingers and finally discharged into the pan or receptacle 49. The latter may be readily removed When full .for the purpose of carrying the severed glass nibs or projections to the dump or trash-pile.

Then the machine is used in the form in which it is illustrated in Fig. 2 of the drawings, the hollow shaft or sleeve ll is loose upon the shaft lO, and the shaft l0, the driving-gear 35, and the parts connected therewith are idle or at rest. Power being now applied to the hollow shaft or sleeve 1l through the pulley l2, the burner-supporting frame l is caused to rotate upon the support or bearing 7 through the gearing consisting of the gears 15 and 16 and the rack-teeth 17. The various burner-supports 4 and the burners carried thereby are thus caused to revolve about the central support 7. One operator only is necessary, and he is located at the burner to the left of the cam 45 and stripper 48. At that point he introduces the glass articles 39 into the burners 5 as theysuccessvely reach that point and deposits the same upon the glass-holders 36 in the respective burners. Said glass-holders having been previously adjusted to the proper height, the glass arti- IOO IlO

erases cles 39 are subjected to the action of the thin annular jets of flame issuing from the burners 5, and the nibs or projections at the upper ends thereof are severed or cracked along the proper lines. As the burners 5, carrying the glass articles 39, reach the cam 45 and the stripper 48 the said articles with the nibs removed are automatically dropped down upon the carrier 47, whence theyare conveyed from the apparatus, and the nibs or projections at the upper ends of the glass articles are lifted off by the stripper 48 and caused to traverse said stripper and finally be de posited in the pan or receptacle 49.

When it is desired to convert the machine into one requiring the services of one operator for each burner and having the different burner-supports and burners carried thereby rotatable upon their respective axes, the gear 1G is uncoupled from the gear 15 and the rack-teeth 17 by the means described and the hollow shaft or sleeve 11 is locked to the central shaft 10 by tightening the setscrew 14. The rotation of the hollow shaft 11 by the power derived through the pulley 12 thereon now has no eiect upon the burnersupporting frame 1, but does rotate the shaft 10 and the driving-gear 35, connected to said shaft. The frame 1 therefore remains stationary, and one operator is necessary at each burner. Each of the burnensupports 4, carrying a burner 5, is rotated upon its axis by the engagement of the driving-gear 35 with the cog-teeth 34. rIhe operator at each burnerfeeds and discharges his particular burner independently of the others. course when the apparatus is used in this form the cam 45 and the stripper 48 are dispensed with. I also employ a slightly-different form of glass-holder, as illustrated in Fig. 3 of the drawings. The glass holder 50, upon which the glass article 39 is supported, is adjustably mounted on the bracket 51 and is provided with a vertical stem 52, which extends loosely through the bracket 51 centrally of the burnersupport 4 and extension 3. The glass-holderOn is adapted to be elevated by means of a rod 53, extend ing through a guide-bracket 54, secu red to the arm 2, and has a socket 55 at its upper end adapted to receive the lower end of the stem 52. Thelower end of the rod 53 is pivoted to a lever 56, fulcrumed upon an upright 57 and connected through a link 58 with an operating-lever 59, fulcrumed upon an upright or standard 60. By depressing the free end of the lever 59 the rod 53 is through the connections described elevated and brought into engagement with the lower end 0f the stem 52. The glass-holder 50 is thereby raised, carrying with it the glass article 39, which has had its nib or projection cracked off or removed through the action of the` burner 5 and ready to receive a new glass article to be subjected to the cracking-olf action of said burner.
