SPECIFICATION forming part of- Letters Patent No. 776,343, dated November 29, 1904.

Application filed July 15,1904. Serial No. 216,670. (No model.)

To nil 107mm it may concern:

Be it known that I, JOHN J. McOUE, J r., a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Apparatus for Use in Polishing Cut Glass, of which the following is a full, clear, and exact description.

My invention relates to apparatus for use in polishing-cut glass by means of dipping the cut article in acid.

It has been found that the polishing of cut glass by mechanical methods is much less eliicient than by means of an acid-bath. WVhile my invention is especially designed for carrying out this process, it will be understood that it is not strictly limited thereto and is capable of other uses.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a preferred form of my invention, showing the method of holding articles of cut glass therein. Fig. 2 is an end view of the same; and Fig.8 is a fragmentary sectional view, on an enlarged scale, showing the operation when the article operated upon is inserted in the acid-bath.

(4 represents a base-plate which is provided with standards 7). These standards are screwthreaded for supporting a cross-bar c, which is held in adjusted position by means of nuts (11. It will be obvious that the cross-bar ccan be placed at any desired distance from the base-plate and secured in adjusted position by means of the nuts 0?, as indicated in dotted lines in Fig. 1. Upon the cross-bar are adjustably mounted a series of holding devices a, which are preferably provided with screwthreads and with operating-handles 0. Upon the lower end of each of these holding devices is swiveled a hollow head f, designed to be placed in contact with the surface of the article to be operated upon, so as to secure the latter firmly in position. These heads are provided with a knife-edgef, which is in turn provided with one or more slots or openings f Each clamping element a is provided with a cylindrical portion a for swiveling the head f thereon.

g g are a pair of upright rods secured to the cross-bar 0 andv provided with a handle 7.

la. is a rubber sheet secured upon the plate a.

The manner of securing the cut-glass articles in this device will be obvious. In the first place the cross-bar 0 is adjusted sulfi-' sequently the articles, which are usually hol low and are provided with a circular rim, are placed face down, as shown in the case of the tumbler illustrated in Fig. 1. The open edge of the article thus being pressed firmly upon the rubber sheet 76, no acid can enter the inside of the article. The heads are constructed in the manner illustrated and described, because if made solid they would prevent the acid from coming in contact with a portion of the upper surface of the article; but when provided with the knife-cdgesf' these edges will protect such a very small portion of the surface from acid that it will not be noticeable and will not detract from the appearance and usefulness of the article. The passages or slotsf are provided for the purpose of permitting the acid to enter the inside of the head, so as to act upon the entire outside surface of the article.

It will be obvious that the device may be constructed in many other forms and that the particular embodiment of the invention illustrated in the drawings is not the only way in which the invention is capable of being made. For example, the structure illustrated in the drawings is especially designed for use with tumblers, and only four tumblers can be operated upon with the device in the form shown; but it will be clear that more than one crossbar 0 may be employed, so that several rows of tumblers or the articles could be used, and of course a larger number of tumblers or other articles could be placed in the device when using only one cross-bar by the application of obvious mechanical changes.

The use of the three uprights 5 is recommended, for the reason that it prevents springing of the cross-bar c.

Any other form of handle than those shown may obviously be employed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A portable implement for dipping cutglass articles in acid, having means for bolding the articles and for permitting the acid to have access to all parts of the exterior surface, and means for preventing the entrance of acid to the interior of the articles.

2. A portable implement for dipping cutglass articles, comprising a supporting-plate, a bar ad justably mounted with respect to the plate, a series of clamping members adjustably mounted on said bar for holding various articles firmly on the plate, and a rubber cushion on the plate.

3. The combination of a supporting-plate, uprights secured thereto, a cross-bar adjustably mounted on said uprights, a series of clamping members adjustably mounted on said cross-bar, each of the clamping members having a hollow head swiveled thereon and each of said hollow heads having a sharp edge. at. The combination of a supporting-plate, a cross-bar adapted to be fixedly mounted with respect to said plate, and a series of clamping members mounted on said cross-bar, each of said clamping members having a hollow head provided with a sharp edge and with passages through the edge to permit free communication of liquid to the interior of the head.

5. The combination of a supporting-plate, a plurality of uprights secured thereto and provided with screw-threads, a cross bar mounted on said uprights, nuts on said uprights for securing said cross-bar in adjusted position, and a series of clamping members having screw-tln'eaded engagement with said cross-bar and provided with heads for engaging an article to be held by the device.

6. The combination of means for supporting a cut-glass article and closing its open mouth, and means for clamping the article upon said supporting means; said clamping means having a hollow head provided with a sharp edge engaging the outside surface of the article.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
