MAC'HINE' FOR FINISjHING GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 599,822, dated March 1, 1898 Application filed April, 1897. SerialNo. 63o,7s3. (No ode.)

To all whom it may concern:

Be it known that I, WILLIAM FRANCIS AL- TENBAUGH, a citizen of the United States, residing at Tiflin, in the county of Seneca and State of Ohio, have invented a new and useful Improvement in Machines for Finishing Glassware, of which the following isa specification. V

In the operation of finishing glassware IO which requires reheating, such as tumblers,

I use as tools a plug and a cup, the latter re-.

ceiving and conforming to the shape of the tumbler, and with these tools used in successive steps the article is manipulated upon and [5 with correlated parts supported in a frame having a work-table. Of these tools the plug is used with a fixed guide erected upon the table, by which the tumbler is centered in placing it by a punty bottom side up upon zo the plug. The cup is mounted upon avertical shaft, and the tumbler is transferred by the plug within thecup, wherein it is given perfect shape. cup of polished cast-iron to'be better adapted for such a finishing operation than the methods ofvrotating the glass in contact with a stationary pasted or wooden cup. In these particulars my improvements consist in certain novel parts and combinations of parts hereinafter specifically set forth in the claims concluding this specification.

The following description, read in connection with the drawings, will enable any one skilled .in the art to which my invention re- 3 5 lates to understand itsnature and to practice it in the form in which I prefer to e'mploy it; but it willbe understoo djthat my invention is not limited to the precise form herein illustrated, as various modifications may be. made 40 without exceeding the scope of the claims.

It will be understood that the work of this machine is the finishing of tumblers and other articles after they have been reheated in what is known as a glory-hole furnace to reduce the article to a symmetrical form. In this reheating operation the tumbler-becomes more or less out of shap'e, and -my'machine is rapidly and conveniently to give form and finish to the tumbler. i

Referrin g to the drawings, Figure 1 is a ver- I make the inner walls of 'the' tical section of my improved machine, a reheated tumblerbeing shown in position upon the plug, another tumbler having been transferred from the plug to the cup. Fig. 2 is a horizontal .section taken beneath the table, showing the provisions for swinging the cupsupporting shaft to control its rotation and for lifting the tumbler from the cup. Fig. 3 is a vertical transverse section of the' machine. Figs. 4 and 5 are enlarged side views of the swing-frame and of its cup-supporting shaft in different positions. Fig. 6 is a vertical section of the cup-supporting shaft, and Fig. 7 shows the tongs for handling the tumblers. 6 5

In working with the machine the tumbler `is taken from the mold by a punty 1 and carried to the reheating-furnace,heated and placed upon ,the plug 2, which is first placed upon the table and centered by a table-pin 3 in vertical. alinement with guides l in a vertical frame, within which guides the staff of the punty is placed to guide the tumbler vertically upon the plug, in which, position the i tumbler is knocked off the punty. The plug has a sten' 5 with an enlarged end on which the tumbler rests in an inverted position, and the base of the plug is provided' with a semicircular curbor flange 6, within whichthe open end of the tumbler fits and whereby it So is held central upon the plug and is allowed tobe readily transferred from it. By means of a handle 7 the plug is removed and the tumbler thereon transferred into the cup by turning it off of the plug with its open end up.

The'plug is returned to its position to receive another tumbler from the punty to be transferred in the same way. The cup is of metal, preferably of cast-iron, smooth polished on its inner walls to prevent the tumbler sticking thercto. It is seat'ed upon the shaft 9, by which it is rotated, and in' its rotation its shaping may be aided by a butter of Wood or other suitable material.

The cup-supporting shaft is mounted by a suitable step 10 and bearings 11 in a Vertical hanger 12, hung by a horizontal arm 13, pivotally connected to the frame 14:, preferably at one end thereof and beneath the table 15, so

that the hanger is free to swing laterally with- Ioo in certain limits with its shaft, there being an opening 16 in the table through which the shaft passes to carry the cup above it. Above the hanger and preferably below the table the shaft has a pulley 17, from which a belt 18 leads to a power-driven pulley for rotating the cup. The belt from the shaft pulley passes under idle-pulleys 19, and the belt is made taut or slaek to control the rotation of the cup by means which I will presently describe.

The cup-supporting shaft is hollow, and within it is fitted a rod 20, having a disk 21, the normal position of which is just below the cup-seat 22, so that when the rod 20 is lifted the disk 21 will lift the tumbler out of and above the cup, as shown in Fig. 5. This lifting of the tumbler is effected by the cord 23, attached to the lower end of the lifting-rod, there being a vertical slot 24 in the shaft for such attachment, said cord passing over a pulley 25 at the top of the hanger and connecting a lifting-arm 26, pivotally connected to the table. This lifting deviee maintains its normal position by gravity, and its cord connection may have a guide-rod 27 to prevent the lifter from binding in its movement in the tubular shaft. Referring to Figs. 5 and 6, it will be seen thatthe lifting-rod has a pin 36 on its lower end which projects through the slot in the shaft and that the lifting-cord connects this pin by an arm or ring 37, fixed to said pin, so that the pulling up of the cord thereby raises the lifting-rod. At its upper end the shaft-hanger has a horizontal stirrup or forked arm 28, situated at or near its Swing side, by which the hanger is swung toward and from the front of the machine to tighten and slack the shaft-pulley-propelling belt to control the rotation of the cup.

The normal position of the hanger is maintained at the limit of its backward movement by a brake 29 under the pulling action of the shaft-propelling belt, and in this position the pulley-belt is slack, so that the cup does not rotate. To render the belt taut for rotating the cup, the shaft-supporting hanger is pulled toward the front and away from the brake by the knee of the fiuisher.

To lift the tumbler from the cup, the lifting cord-connected arm 26 is moved away from the hanger by the knee of the finisher.

In working with the machine the operator sits facing the cup with his left knee in the hanger-stirrup and his right knee against the pivoted arm, which connects the tumblerlifter. The tumbler having been knocked off the punty on the plug, the tumbler is transferred thereby into the cup. The finisher then by moving his left knee to the left pulls the hanger toward the front, thereby tightening the pulley-belt and rapidly rotating the cup, which is fixed upon the shaft, and during such rotation the tumbler is gven the exact form of the cup.

By my invention all defaeement or marring of the surface of the glass article is prevented and the operation of shaping the glass is performed cheaply and rapidly. In this operation the tumbler cools suflicent to allow it to be removed, which is done by the operator changing the pressure of his left knee in the stirrup from a frontward direction to a rearward direction, thereby forcing a hub 30 on the cup-carrying shaft against the suitable brake 29,fixed upon the table, thereby quickly stoppin g the rotation of the cup. Then moving his right knee to the right against the pivoted arm forces it outward, thereby pulling the cord 23 and raising its connected tumbler-lifter, carrying the tumbler above the cup and holding it in that position. The finisher then applying a suitable fork (shown in Fig. 7) to the bottom of the tumbler removes it from the lifting-disk 21 and places it in a seat 31 on a shelf 32, fixed to and projecting from the end of the table. This shelf is provided with one or more rows of seats, within which the tumblers are collected fron the cup, and intersecting these rows of seats there is a surface groove 33, which is for receiving one of the fork-tines in applying it beneath the tumblers to remove them to the tempering-oven.

The knee tumbler-lifting device leaves the 'finisher free to use his hands in the work upon the tumbler, facilitates the work, and enables it to be done with a finishing-cup fixed to its rotating shaft.

The frame may have rolling supports for convenience in using it.

I prefer to attach the lifting-cord pulley and the stirrup to the same arm and connect the latter to the shaft-hanger; but said pulley may be Suspended from the table.

It will be understood that the cup is open at both ends and is fixed upon an interior shoulder 34 in the cup-seat, that the tumbler rests upon the walls of the cup, that the nornal position of the lifting-disk is below or level with this seat-shoulder, so that in raising the disk it lifts the tumbler from the cup-walls, and that the lifting movement carries the tumbler above the cup to allow it to be removed therefrom without disturbing the position of the cup upon the shaft which carries and rotates it. As seen in Figs. 1 and 6, the seat for the cup is a ring circumferentially screwthreaded and engages the interior-threaded hub fixed on the end of the shaft, whereby the cup-seat may be adjusted vertically to raise or to lower it within the annular space at the top face of the hub to allow for slight variations in the size of the tumblers. In this adjustment the tumbler may go slightly through the cup and rest upon the liftingdisk, so that each tumbler is thereby exactly formed the size of the cup. As the cup-seat would be liable to turn, I provide for fastening the cup-seat when set by its flange to the shaft-hub by means of a pin 35, which passes through the seat-fiange into one of a series of holes in the rim of the hub, as seen in Fig. 6.

WhileI prefer to make the cup'of cast-iron,

IOO

polished on its finishing-walls, it maybe made of other metals or of' similar substances that will furnish hard polished walls on which the tumbler is finished and that will resist the effects of the heat.

I claim as my improvement- 1. In a machine for finishing glassware, the combination with a fixed table and a brake device fixed thereon, ashaft having a finishing-cup, above the table, and a belt-driven pulley, a Swing-hanger for said shaft, a stirrup or arm on said hanger wherebysaid hanger may be swung to cause the cup-supporting shaft to engage said brake and means for rotating said shaft.
