IMPROVEMEN'I IN HOLDERS FOR TUMBLERS.

' Specification forming part Vof Letters Patent No. 176,525, dated April 25, 1876;` application filed March 27, 1876.

To all whom 'it may concern:

Be it known that LGI-JORGE WFRY, of

Rochester, in the State of Pennsylvania, haveinvented Va new and useful Improvement in Holders for Tnmble'rsyand I hereby decla're that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specication, vand the lettersof referenee marked lthereon,iu which the same let-A ter represents the saine thing in each ligure.

Figure l is a front -view of a holder embodying my inventionfyvith a tumbler attached.

Fig. 2 is a sectional viewof the same.

Tumblers, after being molded, pressed, or

,blown into the'desired shape, are attached at their bottoms to a rod Ior punty, and held in a furnace untila desired degree ofheat has V been `attained townish it, and then the tumbler is nished upon the top or sides, as may be required. `The mode of attachment consisted in having uponWthe end of the rod or punty a projection of suicient size, and then rolling it around `in the molten glass until enough glass should adhere to enable atumbler to be sufficiently secured when Vpressed upon the bottom, so asrto allow it .to be linished as desired. Upon removing the tum! bler the bottom-is leftrough and uneven, and

. requires an additional `operation to make it .1A smooth enough to render it salable. Snap catches or springs have also beeuused as means of attachment when the article was of such shape that it couldbe held by any such device. In this case the impression of the snap or catch was usually left upon the article when lnished, and injured its appearance.

My invention consists in constructing a holder with an air-"tight chamber and dat smooth holding-surface, in such manner that when the holder is placed upon the bottom of the eylinder-head D, and may be made long enough so as to form the main handle of the holder. F is a pipe, large enough for the piston-rod to slide through, and is connected with the cylinderhead D by means of a nut,

or in any suitable manner, the connection be` ing made air-tight by packing, or otherwise. G is a disk or bearingsurface, which presses upon the bottom of the tumbler, and is connected with the air-cylinder by -meails of the pipe H, which is securely fastened to the head E of theair-eylinder. This disk has an opening, I, leading through the pipe H intoV -the aircylinder. The cylinder-heads may be screwed on or secured by bolts, as may be preferred. Before securing the top cylinderhead the pistou must be drawn .up to the top, so that when the piston is lforced down a vacuum will be created between the piston and the top cylinder-head.

To use my improved holder, lrst force down the piston by means of the piston-rod; the air in the cylinder will escape through the opening in the disk, and a vacuum will b e created 'between the piston and the top cylinder-head.

Then apply the bottom ot' the tumbler to the disk and remove the pressure from the piston rod, and the atmospheric pressure upon the tumbler will hold it securelyv upon the disk. To remove the tumbler, press down the piston-rod, and the tumbler can easily be withdrawn from the disk.

I do not confine myself to the precise form of theparts herein shown, as modifications thereof may be made which wil-l produce the same result. v

I claim as my invention- 1. Securing a tumbler on the end of a holder by atmospheric pressure,substantially in the manner and by the means described.

2. The combination of a disk or holdingsurface, having an opening for air, with an air-chamber, piston, and piston-rod, substantially as and for the purposes herein set forth.

3. The combination of a disk or holdingsurface, having an opening for air, and the connecting-pipe, with an air-chamberpiston, and piston-rod, substantially as and for the purposes herein set forth.
