UNITED STATES ATENT FFKCEO TOOL FOR MAKING GLASS PITCHERS, 81.0.

SPECIFICATION forming part of Letters Patent No. 233,672, dated October 26, 1880.

Application filed April .14, 1880.

To all whom it may concern:

Be it known that I, WILLIAM HALEY, of the city of Pittsburg, Pennsylvania, have invented a new and useful Improvement in the Process of Making Pitchers, &c., which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

Similar letters of reference indicate correspondin g parts.

This invention relates to improvements in the manufacture of glass pitchers and other articles in glassware; and it consists in the novel construction and arrangement of a snap, which is used for the purpose of holding a pitcher or other articles of glassware, and at the same time facilitate the trimming and forming of the same, as will be hereinafter more fully explained.

In the annexed drawings, to which reference is made, fully illustrating my invention, Figure 1 represents a side view of the apparatus used in carrying out myinvention. Fig. 2 designates an edge view of same. Fig. 3 is a view of the pitcher before it has been formed and trimmed. Fig. 4 is a view, showing the pitcher after it has been formed and its edges trimmed.

By reference to the drawings, A designates the snap proper consisting of a hollow standard, A, at the upper end of which, secured thereto or cast therewith, is a cross-head, B,

having pivoted therein the arms 0 of the jaws or former O, which former is provided on its outer face with cars a for the reception of the upper end of acrooked arm, D, passingthrough a slot in cross-head B, and having their lower ends connected to a link-bar, b. The inner end of the latter is pivoted to a sliding sleeve or collar, 1), on the standard A, and is operated by means of a coil-spring, c, placed within said hollow standard and encircling a plungerrod, E. The upper end of said spring cbears against a shoulder, d, in the standard A, and the lower end of said spring rests against the shoulder d on the plunger-rod E, as clearly shown in Fig. 1. Through the upper end of the rod aforesaid, and passing through the sleeve or collar 1), is a pin, 6, playing vertically through a slot, f, in the hollow standard A, which regulates the movement or stroke of the plunger-rod, and thus prevents the sleeve or collar b from becoming misplaced.

(Model) The crooked arms D are further provided near their center with slots f, passing through the same 5 and also through the cross-head B are pins g, for the purpose of serving as a guide for the "ertical and vibrating movement of the crooked arm D aforesaid.

The operation of my invention is as follows: To insert a pitcher or other article of glassware in the former or jaws O 0, this is accomplished by pressing the rod E, thereby causing the sleeve orcollar 1) to move vertically on the standard A, taking therewith the link-bar b, at the same time drawing the lower end of the arms D D inwardly, which has the effect of causing said arms to swing on pins g g. By such movement above mentioned the jaws or formers are separated or opened for the introduction of articles of glassware. The reaction of the spring 0 causes the jaws G to close and embrace the pitcher or other article, and securely holds the same while bei n g formed and trimmed.

It will also be observed that the inner faces of the jaws O O are shaped to correspond with the upper end or neck of the pitcher.

It will further be seen that the surplus glass usually adhering to all articles of glassware after being blown, as shown in Fig. 3 of the drawings, is placed in the snap, and the upper end is sheared or trimmed off to conform with the shape of the pivoted arms 0 G and jaws C O, as at h h. The flaring-tool may then be introduced to impart the proper finish or shape to the upper end of the article to be flared. The flaring is done by pressing a piece of wood of the proper shape against the inner surface of the upper edge of the article, and pressing the same against the faces of the jaws O O, in the usual manner well known to glass-blowers.

After the body of the pitcher has been formed and the mouth flared, as described, a pressed handle or handles, or other desirable projections to be used in taking hold of the pitcher or like article, are attached to the body thereof by the ordinary method of cutting a little hot glass and dropping the same on the placeswhere the pressed handle has to be united to the body. of the article.

I am aware that snaps have been made and used of various constructions, and that blowpipes have been attached to snaps for blowing and forming glass vessels requiring handles,

&c., and therefore do not claim what is contained therein; but

What I do claim is 1. In a snap for forming glass pitchers, the combination of arms 0 (J, with thejaws O G, pivoted to the cross-head B, and provided with the arms D I), connected to the sliding sleeve or collar 1) by links I), and operated byineans of the coil-spring 0, for the purpose of opening and closing said jaws, as and for the purpose set forth.

2. The method herein described of shaping the neck and mouth of glass pitchers and other articles of glassware, by reheating the same in thctsnap A, the jaws G C of which correspond to the form to he imparted to the article,then trimming and flaring of the same to conform to the shape of thejaws, as specified.

WILLIAM HALEY.
