SPECIFICATION forming part of Letters PatentNo. 663,023, dated December 4, 1900.

Application filed February 2, 1898. Serial No. 668,802. (No model.)

To a/ZZ whom it may concern:

Be it known that I, AUGUSTUS H. HEISEY, a resident of Idlewood, in the State of Pennsylvania, have invented a new and useful Improvement in Machines for Finishing Articles of Glass ware; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to machines for finishing articles of glassware. y

The object of my invention is to Aprovide a machine in which the finishing-tools which revolve around the article are gradually brought into contact with the article, their pressure against the article being governed by centrifugal force.

To this end my invention comprises, generally stated, a shaft having pivotal arms mounted thereon,c arrying the finishing-tools, and means for imparting a gradually -increased speed to said shaft, whereby the centrifugal force will act to force the finishingtools into contact ,with the article.

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 a longitudinal section of my im- Fig. 2 is a plan View of a portion of the machine. Fig. 3 is a different form of my invention, in which the iinishingtools work on the interior of the article. Fig. 4 is a section on the line 4 4, Fig. 3. Fig. 5 is another arrangement of the finishing-tools.

Likeletters indicate like parts in each of the figures.

The let-ter ot designates a portion of a suitable frame upon which the working parts of my invention are mounted. Within the bearings b in said frame is journaled the vertical rotary shaft c, said shaft being free to move vertically in said bearings. For the purpose of raising and lowering said shaft c a treadle d is provided, with its forward end engaging the lower end of said vertical shaft c. A pulley e is secured to the shaft c, said pulley to be driven by a suitable belt. At the upper end of the shaft c is the speed-regulating disk f, which has the central boss f', with the beveled face f2. Beginning from the base of said boss f' the upper face of the disk f has the spiral gnideway or groove j"g formed therein, extending to the outer rim of said disk. The uprights a' of the frame ot have the bearings a2, in which is secured the horizontal shaft g. The outerend of this shaft g carries the former g, which may be of any suitable shape, that shown being of a shape to conform to the in- `terior of the ordinary tumbler. This former g' is secured to the shaft g by means of the screw g2, so that said former may be readily removed and another of different form substituted therefor. Surrounding the shaft g `and free to rotate thereon is the shaft 7i, said shaft being held against longitudinal movement by the collar 7L. Secured to the forward end of the shaft h is the collar i, with the lugs t" formed thereon. To these lugs t" are pivoted the levers la. On the forward ends of the levers k are the finishing-tools Z. These tools are in the form of rollers and are free to revolve on the spindle ends lo of said lever. Other forms of tools may, however, be employed. Links m connect the inner ends of the levers 7o to the sliding ring m on the shaft h. A spring n, interposed between the ring m and the bearing a2,acts to compress the inner ends of said levers 7.0, and consequently throws the outer ends thereof apart. Weights o are adjustably secured to the levers lo. Brackets p, extending up from the frame, have the guides p', which support the longitudinallymovable rod q. Secured to the rod q and depending therefrom is the fork fr', which eugages the flange 'r2 on the'sliding sleeve o'. The sleeve r has the key r3, which engages with the keyway h2 in the shaft h. At the opposite end of the sleeve r is the enlarged fiange r4, which has its periphery so formed as to engage conveniently with the groove f3 in the disk f. A cord or like flexible connection s is secured to the end of the rod q, said cord passing over the pulley s and having the weight s2 secured thereto, the tendency of the weight being to bring the sleeve r in such position that the flange 'r4 will engage with the beveled face f2 of the boss ff, or, if not engaging therewith, will be adjacent thereto.

In Fig. 3 I have illustrated another form of my invention in which the finishing-tools are arranged to act on the interior of the arti- IOO Fig. 5, attached to the outer tools.

cle instead of on the exterior, as above set forth. As the modification v only relates to the forward end of the machine, I have only illustrated that portion.

The letter t represents the stationary shaft, and t the rotary shaft. Within the forward end of the shaft t' is the rod t2. A spring t3 encircles the rod 152, being interposed between the cap 254 on the outer end of the shaft t and the head 155 of said rod i2. In order to effect the rotation of the rod t2 with the shaft t, a pin t6 in the rod t2 engages with the slot 257 in the-shaft t', whereby said rod has also a certain amount of longitudinal play. Pivoted to the lugs u on the cap t4 of the shaft are the levers u', said levers having the spindles u2 at the forward end thereof, on which the finishing-tools ug are mounted and adapted to rotate. Links a4 at the end of the rod t2 are also connected to the levers u', forming a toggle-joint. As in this instance the tools act on the interior of the article, it is necessary to support the article from its exterior. Accordingly the mold 'u is provided, which is partible, its halves being hinged by the pin v. This mold is opened land closed by the lever v2. The inner end of the lever v2 is secured to the arm e3, said arm passing up through a guide in the frame and being connected at its upper end to the links y y. These links y y' are each connected to the mold-halves, respectively. It is apparent that by the movement of the lever e2 the mold U is readily opened and closed.

In Fig. 5 I have illustrated a different arrangement of the finishing-tools. This applies to cases Where the tools are applied to the exterior and interior of the article at the same time. In this view the letter a; represents the rotary shaft. The tools fr are the ones which act on the exterior of the article, and they are pivoted to the head 002 of said shaft The inner ends of said tools have the `teeth x3. The teeth x3 mesh with corresponding teeth z3 on the inner ends of the tools z', which act on the interior of the article. The inner tools z are made slightly heavier than the outer tools, so that when the shaft rotates the centrifugal force will tend to throw out the tools e to a greater extent than the outer tools x', and the teeth of the inner tools meshing with the teeth of the outer tools will act to draw in the outer tools. In this manner one set of tools works on the eX- terior of the article while the other works on the interior. Instead of having the inner tools heavier than the outer ones I may employ the weighted arms shown in dotted lines,

The centrifugal force will throw these arms out and the tools x in, whereby the inner tools z will be thrown out.

The operation of my invention when in the form shown in Fig. l is as follows: In starting, the sleeve r will be in the position shown in dotted lines, Fig. 1-that is, the enlarged fiange r4 will be adjacent to the beveled boss f. The article S to be finished, which in this case is a tumbler, is mounted on the snap 4t and having been properly heated is advanced onto the former g'. The snap is supported in the upright 5. Theoperator then lowers the treadle dand raises the shaft c. This brings the disk f into contact with the liange r4. The rotation of the diskf rotates the ange r4 or contact member in frictional contact therewith, and consequently the shaft h. As the flange r4 is in engagement with the spiral groove f3 of the diskfclose to the center of the disk, it is apparent that the shaft h will begin to rotate slowly; but as` the spiral groove f3 carries the flange r4 toward the periphery of the disk the shaft 71, will rotate at a gradually-increasing speed until the periphery is reached, when the shaft will continue to rotate at the same rate of speed as long as the disk is elevated. This rotation of the shaft h imparts a like rotation to the levers k, carrying the finishing-tools. The centrifir gal force tends to throw the inner ends of said levers apart and the outer ends toward each other. The result is that the tools l are forced into contact with the exterior of the article and revolve in contact therewith. As the shaft h rotates at a gradually-increasing speed the centrifugal force likewise increases gradu.- ally, so that the tools are forced against the article with a gradually-increasing pressure. After the pressure has reached its maximum point or the iiange r4 is engaging with the outermost ring of the groove f3 the tools may be allowed to act on the article until the same has been properly finished. The operator allows the shaft c to descend, freeing the disk j' from engagement with the flange r4. The weight s2 im mediat-ely draws the sleeve r along the shaftg until the iiange r4 is restored to its original position. The flange r4 may be allowed, if desired, to remain in contact with the beveled bossf', so that the shaft h will continue to rotate at low speed. The article finished is then removed and another substituted, when the operation just described is repeated.

When the invention is embodied in the form shown in Fig. 3, the operation is the same as above described, the only difference being that the tools act on the interior of the article. The article 6 to be nished is mounted on the snap? and is inserted in the mold o and the mold closed around it. The grad ually-increased centrifugal force throws the tools into contact with the interior of the article. When the rotation ceases, the tools resume their normal positions and permit of the withdrawal of the article therefrom,when said article is of the form of that shown. In the instances described the tools are carried by centrifugal force into contact with the article; but it is apparent that the article may be carried into contact with the tool.

I do not wish to limit myself to the con- IOO IIO

structions illustrated, as these may be departed from without affecting the scope of my invention.
