SNAP-FOR HOLDING GLASS ARTICLES.

SPECIFICATION forming part of Letters Patent No. 292,685, dated January 29, 185.4.

Application filed May 5, 1883. (No model.)

To aZ/I whom it may concern.-

Be it known that I, HENRY O. SOHRADER, of Wheeling, in the county of Ohio andState of West Virginia, have invented a new and useful Improvement in Snaps for Holding Glass Articles, and I do hereby declare that the fol- .lowing is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in snaps forholding glass vessels during the re heating or finishing process. The object it has in view is the construction of a device of the character described,which will be adapted to use with glass vessels. of various sizes and forms, and which will be simple, cheap, and effective.

To the accomplishment .of the above the invention consistsof the novel construction, arrangement, and combination of certain of the parts, all as will be fully hereinafter described and claimed.

For the better understanding of the invenr tion,reference will be made to the accompany; ing drawings, in which Figure 1 is a top plan View of the device; Fig. 2, a vertical section on line w w of Fig. 1, and Fig. 3 a view in detail.

Like letters refer to corresponding parts in each -of the views.

In the drawings, A represents a long hollow tube or handle carrying on its upper end a metal plate, B, ,to be hereinafter referred to. Inserted into this handle A is a rod, O,which protrudes a short distance below'said handle and extends up to a point near the upper end of the same. Encirclingthis rod is a spiral spring, I),which abuts at its lower end against a shoulder formed on the lower end of the rod 0, and at its upper end against a shoulder formed on the interior of the handle A, as

shown in Fig. 2 of the drawings. At a point near its upper endthe rod (3 is provided with an opening,into which is inserted and secured a pin, a, the ends of this pin passing through a slot formed in the handle A and secured to a collar or sleeve, E, passed around said handle, as shown.

By means of the construction thus far described,when pressure is applied to the rod 0,

formed on the lower ends of the bell-crank levers F. These levers F are pivoted at or about their centers between suitable depending arms or brackets, (1, cast on the under side of the top plate, B, before referred to.

Upon the upper end of each of the levers F is formed a ball shaped enlargement, e, which enlargements are inserted into recesses or cavitiesf, formed in suitable horizontally-moving jaws, G, now to be described. These jaws consist of metal pieces pointed at their inner ends and having their edges beveled, so as to fit in suitable dovetail grooves, f f, formed in the upper face of the top plate,B. These grooves extend entirely across this plate B, and are formed at right angles to each other, crossing at the center of the plate and forming an open space, f, as shown in Fig. 1.

Upon the upper face ofeach of the jaws G, and at the outer end of the same, is secured or cast a piece, G, which pieces are preferably curved on their inner faces, so as to enable them to fit more'closely against the glass article to be held between them. When the device is not in use and the jaws are in their normal position, their inner or pointed ends are brought together, so as to present, with the top plate, B, a solid appearance.

The operation of the device is as follows: Pressure is applied to the rod 0, and through the medium of the pin a, which is secured to the upper end of this rod and to the sleeve E, said sleeve is moved vertically on the handle A. This motion elevates the short arms 0, which are secured between this sleeve and the bell-crank levers F, thus operating these levers, and the jaws G, to which they are attached, are drawn apart, thus leaving sufficient space between the curved pieces G for the insertion of the article to be operated upon. When the foot or base of the article has been placed between these pieces G, the pressure is withdrawn from the red C, and said rod, together with the sleeve E, forced down by the spiral spring D,which action forces thejaws G inwardlyand brings the curved pieces Gagainst the foot of the article which has been inserted between them, thus holding said article firmly in position. \Vhen the article has been operated upon and it is desired to remove it from the snap, pressure is again applied to the rod 0 and the j aws G drawn from co ntaet with the foot of said article, the article itself being thus re moved and the jaws allowed to assume their original position by with drawing the pressure from rod 0.

The advantages of my device over those used for a similar purpose are, first, one device may be employed with articles of a great variety of sizes and forms; second, by means of the construction employed a different number of holding jaws or snaps maybe used, the device operating equally as well with two, three, or four of such jaws; third, the device is simple in construction, cheap, durable, and effective.

Having thus described myinvention, what I olai n1 as new therein, and that for which I de sire to secure Letters Patent, is

In the device described, the combination, with the hollow slotted handle A, provided with the spring-actuated red 0, pin a, and sliding collar E, of the arms a c, bell-crank levers F, and beveled-edged jaws G, sliding horizontally and radially in dovetail grooves ff of the top or bed plate, 13, substantially as described and shown.

In testimony whereof I affix my signatnrein presence of two witnesses.

HENRY C. SCHRADER.
