GLASS-BLOWING APPARATUS.

Specification of Letters Patent.

- Patented May 18, 1915.

Application filed January 5, 1914, Serial No; 310,487. Renewed April 16, 1915. Serial No. 21,847.

To all whom. it may concern:

Be it known that I, PIERRE J. Pannier, a citizen of the United States of America, residing at Salem, in the county of Harrison and State of West Virginia, have invented certain new and useful Improvements in Glass-Blowing Apparatus, of which the fol-- lowing is a. specification.

This invention relates to certain new and useful improvements in glass blowing apparatus and more especially to such class of devices in which a blowing and a suction is mechanically eii'ected.

An object of the invention is to provide an air blowing and an air suction member operatively connected with the blow pipe for operating upon the glass cylinder which is being manufactured, for instance in the process of making sheet glass.

A further object is the provision of an elevating device for the blow pipe with its glass cylinder so arranged that the blow pipe is automatically disengaged from the air tube at a predetermined point in its Vertical line of travel.

Another object is to provide in connection with an air tube having an operating suction and blowing fan, a graduating valve for the tube adapted for automatically opening and closing upon imparting vertical movement to the blow pipe and said tube.

A further object is to provide an air damper in the air tube of the blowing system govcrnable for eXhausting desired quantities oi air therefrom.

A still further object is the connection of a separate suction and blowing fan with the pipes of the air tube system and whereby said fans may be governed atwillin con nection with the air tube and the blow pipe while the piping ot the system is advantageoiiisly hinged for allowing a vertical movement ol the blow pipe relativeto the main stationary piping.

Another object is the provision of a vertically movable hoist having stationary vertical guides and furnished with means for disengagealily supporting the blow pipe and air tube, each in relatively movable positions.

A still further object is to provide a swinging horse adapted for receiving the glass cylinder when vertically positioned upon the hoist and operable for moving the cylinder to a horizontal position suitably cushioned by means carried by the horse.

With these objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like reference numerals, designate corresponding parts throughout the several views :Figure 1 is a side elevation of the apparatus illustrating the bait of the blowing pipe as collecting its quantity of glass from within the collecting ring of the glass pot, the ring and pot being shown in section. Fig. 2 is a sectional detail View of the regulating valve in the air pipe or the system. Fig. 3 is a view similar to Fig.1 but illustrating the glass cylinder as completed and with the blow pipe separated from the air tube, the air tube, blow pipe and cylinder being shown in their elevated positions. Fig. 4 is a sectional detail view of the air damper found in. theair tube. Fig. 5 is an enlarged detail view of the tripping hoist mechanism supporting the air tube and blow pipe, the air system pipe and glass cylinder being broken away. Fig. (l is a detail. view of the regulating valve shown in Fig. 2 looking into the piping and one of the connections being shown in dotted lines. Fig. 7 is a side elevation of the swinging horse about to engage the vertically sus' pended glass cylinder, and Fig. 8 is a similar view showing the cylinder resting horizontally upon the horse.

In the operation of mechanically blowing glass into cylinders for the manufacture of sheet glass it is desirable to provide a carricr for the blow pipe and bait, whereby the latter may receive the desired quantity of glass from a point within the collecting ring and may then be elevated during the blowing operation and until. the completion thereof while a suction device is serviceable for then exhausting the air from the cyliu der. It is now devised therefore to provide a blow pipe 10 having an upper and a lower annular ring 11 and 12 respectively, while the pipe at the bottom thereof terminates in the usual bait 13. The air tube 14: is adapted to lit over the upper end of the blow pipe 10 and rest upon the upper side of the ring 11, while this tube is connected by the regulating val vc 15 illustrated in Figs. 2 and 6 to the hinged piping 16 and 17 of the stationary air piping 18 of the system.

Forsupplying air under pressure to the piping system for use by the blow pipe 10,

having the operating rod 26. A damper 27 within the connecting pipe governs the flow. of air from the fan 19 to the system, while a similar valve 28 in thetransverse pipe 23 controls the suction action of the M1121 upon the air'piping system. I

A hoist block 29 is provided'upon one or both of its opposite sides with rings or eyes 30 slidably engaging the guide rods 31 secured to the ceiling and passing there- 'through, A hoisting cable 32 passes over the pulley 33 also secured to the ceiling and is connected to the upper end of the hoist block as at 34, it being noted that the weight of the block normally retains the same in its [lowered position, while the cable is utilized as an elevating means.

- Three hooks or. open semicircular brackets are secured in alinement to the inner face of the block 29 and adapted to receive the blow pipe .therein with the ring 11 supported by resting upon the upper face of the hook-35. lith the air tube 14 resting nponathe. ring 11, a further hook '36 upon the block 29'za1icl'siinilar to said'hooks 35 is adapted to receive and assist in positioning said air tube while a pivoted hook 37 of silnilfaitdiorni and provided with a rear extensionor handle 38 is pivoted to the top of said block as at 39, While said hook is normally positioned and swung beneath the annular ring 40 of the tube 14 as illustrated in Fig. 1.

With the apparatus positioned as shown in Fig. l, thebait has received a quantity of glZtSS".l:1"fFOIrlf2L point within the annular collecting ring '42 *positioned upon the molten glass 43 of the" pot 44. With the hooks positioning the blow pipe 10 and the pipe ring 11 resting upon the upper hook, an upward movement'of the hoist block being imparted by the cable 32 elevates not only the blow pipe 10 and its bulk of glass 41, but

- also the air tube 14 resting upon said ring 11, so that the valve 27 may be opened to allow the fan 19 to blow directly through the piping system to the blow pipe and its glass, during the'drawing operation in Fig. 5.

and thereby forming the glass into a cylinder 45 simultaneously with its upward movement.

. When desired to exhaust the air from the glass cylinder 45, the blower valve 27'- may be closed and the suction valve 28 opened, whereby, with the damper 25 opened, the suction fan 21 will accelerate and thereupon a closing of the damper 25 will forcibly exhaust the air from the piping system and the glass cylinder 45.

.The graduating valve 15 consists of the connecting pipe sections 46 and 47, each having a portion of its diameter closed by a block 48 and so arranged that the com- ,municating' passage is substantially half:

open when the pipe hinge and the piping are positioned lowermost as shown in Fig. 1, but will be opened at its widest extent when the pipe hinge is positioned at its upper limit of travel as shown in Figs. 3 and 6. The molten glass being gathered as shown in F 1 with the blow pipe and bait in its lowermost position,th e hoisting mechanism is elevated as rapidly as desired, while the blowing andsuction fans 19 and 21 are suitably regulated for their desired effect upon the glass. At substantially the limit of'the upward travel of the hoist block, the regulating valve 15 will be automatically fully opened by means of the pipe hinge blocks as hereinbefore described, while the arm 38 of the hook 37 will engage the stationary hook 49 secured to some stationary member 50, so that the continued upward movement of the hoist block tilts the hook 37 upwardly upon its pivot 39 whereby said hook engages i beneath the 'collar 40 of the tube 14, automatically'unseating said tube from the supporting ring 11 and entirely disengaging said tube from the blow pipe as best shown Within theair tube 14 a plate or cylinclosely fit therein and .provided with a projecting pin 52 protruding through the angular slot 53 of the tube and whereby the sleeve drical sleeve 51 is positioned adapted to slot 53 upon the proper manipulation of the pin 52 as will be at once evident from an in spection of Fig. 5 of the drawings.

The complete operation of the device will be apparent from the above detail description from the time of attaching the bulk of glass to theblow pipe bait until the blow pipe with its completedcylinder is automatical-1y disconnected-from the air tube. The action of the blowing'as well as the suction fan for operating upon the glass throughthe air piping is also clear and the manual regulation of both blowing and suction air as well as the automatic reguluating valve 15.

Whenever desired also, the sleeve valve 53 move the same from the hoist by means of the horse consisting of the frame 60 hinged at 61 to the floor 62. A longitudinal slot 63 at the upper end of the frame is engaged by the sliding roller 64 rigidly secured to the endless belt 65, which belt passes over the drum 66 and the pulley 67 thus giving a swinging movement to the frame upon a movement of the belt by means of the motor 68 in either direction and controlled as desired. At the-upper end of the frame an extending arm 69 braced by the rod 70 terminates in a hook 71 of semicircular form and adapted to engage beneath the ring 12 of the blow pipe 10 and to thereby support the same and upon a downward movement of the frame to elevate the blow pipe ofi the book 35 of the block 29 upon which it has been resting. Spring mounted semicircular brackets 72 are spaced apart fromthe frame 60 and adapted to receive the glass cylinder cushioned thereon, while the frame 60 is provided with a spring-pressed foot 73 upon its lower side and adapted to rest upon the floor when the frame and cylinder are positioned horizontally as shown in Fig. 8.

The operation of the take down device will be clear from this description, it being designed to remove the completed glass cylinder from its support and to change its position from the vertical to the horizontal reclining position without any liability of injury to the cylinder. It is apparent that the cylinder may then be transferred from the horse or may be treated thereon or annealed in the usual manner.

While the forms of the invention herein shown and described are what are believed to be preferable embodiments thereof, it is nevertheless to be understood that minor changes may be made in the form, proportion and details of construction without departing from the spirit and scope of the invention set forth in the appended claims.
