.APPARATUS FOR FINISHINGIARTICLES OF GLASSWARE.

SPECIFICATION forming part of Lei-.ters Patent No. 625,468, dated May 23, 1899.

Application tiled June 18,1898. Serial No. 683,798.' (No model.)

T0 @ZZ whom t may concern:

Be it known that I, CHRISTIAN Z. F. Rorr, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Finishing Articles of Glassware; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to apparatus for firepolishing articles of glassware.

The object of my invention is to provide a simple form of apparatus of this character which will convey the articles of glassware fed thereto to the proper position with reference to the heating-furnace and there manipulate said article in such a manner as to firepolish it thoroughly and convey it away without the employment of any labor other than that required to feed and operate the machine.

To these ends my invention comprises the novel construction set forth in the specification and claims which follow.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which- Figure l is an end view in elevation of my improved apparatus. Fig. 2 is a vertical cross-section on line 2 2, Fig. l. Fig. 3 is a plan view. Fig. 4 is a diagrammatic view of the movements of the transferring mechanism. Fig. 5 is an enlarged detail View of the supporting-rollers and mechanism for adjusting the same. Fig. 6 is a modified form of supporting-rollers.

Like letters indicate like parts in each of the figures.

The letter A designates a suitable frame for supporting the apparatus. Extending out from the frame A is the bracket a, in which is journaled the shaft af. Secured to the outer end of the shaft a is the hand-wheel a2, by means of which said shaft is revolved. This shaft ct may, however, be operated by other than hand-power. A sprocket-wheel b is mounted on the inner end of the shaft Ct', and a sprocket-chain b' connects said wheel with the sprocket-wheel b2 on the shaft b3 in the hanger A', depending from the frame A. A gear-wheel c on the shaft b3 meshes with the pinions c c2 on the shafts c3 c4, respectively, journaled in the hanger A.

Secured to the ends of the shafts c3 c4 are the cranks cl CW, respectively. The crankpins d2 connect said cranks with the rods ee. The upper ends of the rods e e' have the arms e2 e3, extending in opposite directions, said arms having the forks f f or other lifting means. Secured to the shaft c3 is the eccentric weight.

Mounted on the frame A are the guideboxes h h', which act as supports and guides for thel Shanks 2 of the bifurcated bearings if 'i'. Mounted on shafts 1 in said bearings t 1l' are the supporting-rollers l Z. These rollers may vary in shape and size according to the shape of the articles they are to support. Adj Listing-screws m pass up through threaded openings in the angles m' on the frame, and said screws are adapted to engage the shanks t2, whereby the bearings t t" may be raised or lowered, as desired.

In order to provide for the turning of the Shanks t2 and the adjustment of the rollers at dierent angles with reference to each other, I provide the adjusting-screwn, which passes though the swivels n', supported by the lugs n2 on the bearings t' t. The screw 'n is contracted at about its mid-point, as at n3, said contracted portion bearing against a lug o. The screw n has right and left hand threads thereon. It is apparent from the above that by turning the screw n the rollers l may be moved away from each other and the rollers Z brought correspondingly nearer, or vice versa, according to the size and shape of the article to be supported thereon.

Beyond the rollers ZZ are the receiving-rollers r fr', the rollers fr, together with the adjacent rollers Z Z', acting as a support for the article when it is first received in the apparatus and the rollers r/ acting to receive it as it passes beyond the furnace.

Extending out from the frame A isthe bracket s,within which is j ournaled the powerdriven pulley s'. An endless belt s2 passes from the pulley s up under -the pulley s3, up over the pulley s4, thence down under pulley S5, up over pulley s6, and down under pulley .S7 to the pulley s. Through power imparted IOOv in this manner the rollers Z Z' are made to revolve in the same direction.

Supported on tracks t on the frame A are the furnaces t', said furnaces being of any suitable construction, with refractory lining, and having the glory-holes t2 facing each other. The furnaces are mounted on the wheels Z8, which ride on the track i. Gas-supply pipes u enter the furnaces from below and furnish fuel thereto. Gas is admitted to said pipes by the openings u', s'aid openings being connected up by flexible pipe with the main supply. The glory-holes Z2 are preferably contracted in the form of segmental slots, as shown, and project up ata slight angle in order to direct the heat more effcctually onto the object to be hre-polished. Furthermore, a recess or depression t4 is formed in the face of the furnace, Which forms a kind of pocket to retain the heat around the object.

To provide for the movement of the furnaces over the tracks toward and from each other, the treadles or foot-levers w are provided. The foot-levers are connected bythe links 'w' with the levers 102, pivoted in the hangersw. Secured to the levers 2v2 are the arms which carry at their upper ends the hooks These hooks 5U' engage with openings in the rings x2, surrounding the pipes u.. It is apparent from the above that by depressing the foot-levers w the furnaces will move away from each other and that by raising said foot-levers they will approach each other for the purposes more fully hereinafter set forth.

I Will now describe my improved apparatus as applied to the fire-polishing of lamp-chimneys, although its use may be extended to all other articles of glassware to which it may be found applicable.

The lamp-chimney y to be fire-polished is placed upon the receiving-rollers r, the rollers ZZ having been previously adjusted by the adj Listing-screws m n to correspond to the shape and size of said chimney. The distance between the furnaces t is also previously arranged by means of the foot-levers w, so as to bring the ends of said chimney in proper proximity to the glory-holes to give the requisite nre-polishing effect thereto. The operator then grasps the hand-wheel a2 and proceeds to rotate same. This rotation of the said wheel through the gearing mechanism operated thereby will cause the rods e e' to rise. The arms ve2 thereof ascending in line with the ends of the chimney y will, through Vthe forks f, lift the chimney from the rollers. These forks then support the chimney at its base and neck. As the hand-wheel continues to revolve the rods e e', asshown in the diagrammatic view Fig. 4, ascend slightly farther, moving over toward the rollers ZZ at the same time. When the highest point has been reached, said rods begin to descend in the same manner, moving toward the rollers Z Z', until they deposit the chimneybetween the said rollers, so that it is supported thereon. The rods then descend out of the way. The chimney is now supported on the revolving rollers Z Z', with its ends in close proximity to the gloryholes. The segmental slots t2, which form the glory-holes, direct the heat radially, and the ends of the chimney being on substantially the same curve a greater portion of the same is subjected to the heat, while at the same time the depressions t4 tend to form pockets for the heat and less heat is wasted. After the chimney has been allowed to revolve in this manner the requisite time to remove any unevenness or roughness on its ends and has been properly fire-polished the operator again turns the hand-wheel d2, when the rods e e follow the same course as before, the arms e3 moving so as to brin g their forks up under the chimney fz/ to lift it from the rollers and deposit it on the receiving-rollers r'. The arms e2 by the same movement have lifted a second .chimney from the roller r and placed it on the revolving rollers Z Z in the same manner as before. In this manner the machine is kept operating continuously, so that each time a chimney is removed from the revolving rollers another takes its place.

The construction shown and described may be modied and varied Without departing from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-
