SPECIFICATION forming part of Letters Patent No. 680,306, dated August 13, 1901.
Application filed March 23, 1901. Serial No. 52,563. (No model.) I
To aZZ whom it may concern:
SON, a citizen of the United States, residing at Clayton, in the county of Gloucester and 5 State of New Jersey, have invented a new and useful Improvement in Tools for Finishing the Necks of Bottles and Similar Glassware, of which the following is a specification.
This invention relates to the finishing of the necks and lips of bottles, and particularly bottles having screw-threads formed thereon adapted to be closed by screw-caps.
The object of this invention is to facilitate the forming of screw-threads of uniform di-' ameter and pitch, with a lip of a true form corresponding with the axis of the screw; and to this end it consists in a combination of an expanding plug with side jaws and a rotating screw-mold, and means of automatically lock ing the rotating screw-mold against rotation to liberate and discharge the bottle-neck from the mold, as hereinafter described, and shown in the accompanying drawings, in which- Figure 1 shows a plan of the tool or implement embodying this invention; Fig. 2, a side view of the same; Fig. 3, a section of the molding portion of the implement while forming the screw-thread; Fig. 4, a section of the molding portion while discharging the finished bottle-neck. Fig. 5 shows a section of the expanding core, and Fig. 6 shows a modification thereof.
Referring to the drawings, aaare two molding-jaws formed on the ends of shanks bb, united at the opposite ends by a bowed spring and covered by handles (Z d of slow heatconducting material, such as wood. Through each of the shanks I) Z), near the jaws a a, are slots 6 e, in which are fitted to slide freely laterally-proj ectin g horns f f, formed on a die g, having a stem 71. extending lengthwise, so as to slide in an aperture 11 in the spring 0. On the die 9 is fitted the screw-mold 9', so as to rotate freely on a stem 7a, which is inserted in the die 9 and extends outwardly, forming a tapering plug Z, as shown in Figs. 1, 2, 3, and 4, and as shown in Fig. this is made of flattened or oval cross-section. As shown so in Fig. 6 it is of circular cross-section. The
flattened form is preferred.
On the stem is is a collar or shoulder m, which forms the bottom of the moldj and holds the moldj in position upon the die g.
The external form of the screw-moldj is polygonal, and the inner faces 12 n of the jaws a a are flat and parallel, so that they can grasp the mold j and prevent it from turning. Parallel grooves 0 0 are formed in the inner sides W n of the jaws a a of a form corresponding to the shape of the bead or rim u to be formed on the neck 0) of the bottle.
A cross-bar p is fitted through the shanks b b, in the center of which is an opening q, through which the stem h slides. A spring r, abutting on the cross-bar p and pressing against a shoulder s on the stem h, presses the stem h and the die 9 toward the ends of the jaws a a. A nut 25 on the stem h, contacting with the spring a, restricts the motion of the stem h in opposite direction.
The operation of the invention is as follows: The workman grasps the tool by the handles (Z d and presses a heated bottle-neck, which he rotates over the plug Z, into the mold j, which recedes with the die 9 and stem h. The jaws a a are pressed toward each other, so as to come in front of the mold j and to close with the grooves 0 0 upon the bead a on the bottle-neck o. The pressure of the col- 8o lar 'm upsets the glass in the mold 1', so as to fill the screw-threads w as the glass is expanded by the plug Z. While this operation is in progress, the mold j rotates freely with the bottle-neck. Upon the completion of the screw-threads theworkman then releases the endwise pressure from the to0l,and the spring 1' by its reaction forces the mold j between the flat surfaces of the jaws a a, which grasp the mold and prevent its turning, and continned rotation of the bottle-neck unscrews it from the mold. The screws thus molded are without seams and are of uniform diameter and pitch, and the lip or end of the bottle-neck is in the true plane at right angles to the axis of the screw and well adapted to fit fluid-tight within a screw-cap.
The circular form' of the plug Z (shown in Fig. 6) may be used with the other parts, as described, but is slower in its operation than the flattened form shown in the preceding figures. The quicker expanding operation of the oval plug finishes the expansion of the glass into the screw-threads of the mold more quickly and does not cool the glass so rapidly as the circular form, which contacts therewith its entire circumferential surface, and consequently requires more force.
Having described my invention, what I claim is- 1. In an implement for finishing exter-v nally-screw-threaded bottlenecks, a rotating screw-mold, a pair of jaws adapted to close in parallel position upon a bottle-neck beyond the screw-mold in combination with means toed to upset'the ends of the bottle-neck, in combination with a tapering plug, adapted to expand the bottle-neck into the threads of the mold and means of retracting the jaws'to allow them to move and to embrace the mold and hold the same against rotation arranged to operate as and for the purpose set forth.
3. In an implement for finishing screwthreaded bottle'necks, a pair of jaws, handles attached thereto and connected by a spring,in combination with a centrally-guided sliding stem, and connected die and rotatable screw-threading mold, secured to said die bya stationary collar adapted to upset the neck of the bottle within said mold, a spring upon said stem, arranged to press said mold to a position between said jaws, and a tapering plug arranged to expand the neck of the bottle into the threads of the said mold and means of holding said mold against rotation between said jaws as set forth.
