DANIEL O. RIPLEY, OF PITTSBURG, PENNSYLVANIA.

GLASS-SHAPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 709,724, dated September 23, 1902.

Application filed May 10, 1902. Serial No. 106,734. (No model.)

To aZZ whom, it may concern:

Be it known that I, DANIEL C. RIPLEY, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Glass-Shaping Apparatus, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a front elevation, partly in sec- 1 o tion,of a glass-shaping apparatus constructed in accordance with my invention. Fig. 2 is a plan View of the same, partly broken away; and Fig. 3 is a sectional elevation at the leer end of the system.

Myinvention relates to the forming of glass articles, preferably by pressing, and is designed to provide an improved system or apparatus wherein the molds may be supplied with glass, transferred to a pressing or shap- 2o ing station, and then returned to the fillingstation.

In the drawings, in which I show my invention in connection with the improved gathering device set forth in my Patent No. 697,886, granted to me on April 15, 1902, 2 represents a glass-melting furnace having gathering-holes 3 in its side. Beneath these holes I show a group of three molds 4., of which any desired number may be used, these molds being mounted on a sliding support 5, having shoes which rest upon track-sections 6. The track sections 6 form part of a frame having transverse lower shoes 7, which travel upon rails 3, extending substantially at right angles to the shoes of the mold support. Two tracks 9 and 10 extend from the gatheringstation in parallelism, and at the other end of these tracks is provided another movable track-section 6, formed as part of a frame having transverse shoes 7 which travel upon on supports 16.

- mold is carried on a cage 18, arranged to slide upon the stem of the plunger against the action of a spiral spring 19, the upper end of which rests against an adjustable follower 20. After the articles are pressed the molds are lowered upon their support, which is then moved upon the track-section 6, where the articles are ejected. For lifting the articles from the molds I show a series of vertical pins or rods 21, secured to a lower cross-head 22 and moving through guides 23. A footlever 24 is arranged to force the pins upwardly. Each mold A is provided with an ejecting-plug 25, having a lower enlarged portion 25, which is guided within an enlarged bore in the mold. The pins 21 move up through holes 26 in the lower ends of the molds and force the plugsupwardly, thus lifting the articles, which are then seized by swinging clamps 27. These clamps 27 are preferably formed of spring-arms secured in pairs to levers 28, projecting from a horizontal rock-shaft 29. The shaft is rocked by a crank 30, which is provided with a pinion 31, intermeshing with a similar pinion 32 upon a lower shaft having cams 33. These cams are arranged to engage swinging latches 34, pivoted to the lower ends of vertically-sliding spreaders or splitters 35, which slide in bearings in a cross-support 36. The spreaders are spring-pressed upwardly and have wedgeshaped upper ends. As the operator swings the clamps in the position shown in full lines in Fig. 3 the spreaders open the clamps and allow them to surround the elevated articles. The operator then reverses the movement of the crank, and thus draws the Spreaders down against theaction of theirsprings,allowing the clamps to engage the articles. As he continues this movement the arms of the clamps are oscillated vertically, thus carrying the articles over until they reach the position shown in dotted lines in Fig. 3 within the mouth of a leer 37 upon the leer-pan or other support. As the swinging clamps reach the position shown in dotted lines in Fig. 3 they are engaged by stationary spreaders 38, which disengage the clamps and release the articles. After the clamps are swung back the articles may be pushed along within the leer by a sliding cross-bar 39, actuated by endless sprocket-chains 40, movable over wheels 41 and over driving-Wheels 42. The clamp-arms are preferably bent upwardly to allow passage of this barforshifting the article. When the articles have thus been removed, the track-section 6 is moved into alinement with the outer track 10, and the mold-frame is moved back along the track 10 to the end next to the gathering-station. It is then taken upon the movable track-section at this end and moved into the position shown in Fig. 2.

In the gathering-machine shown 43 is a shaft carrying'a series of worms 44, meshing with Worm-wheels 45, formed on or fixed to the gathering-irons 46. These gathering-irons are held in brackets 47, mounted on a shaft 48, and are provided with a handle or pilot 49. The shaft 43 is supported on the end of a frame 50, which is journaled concentrically to a driving-shaft 51, from which motion is communicated by sprockets 52 and a chain 53 or otherwise to the shaft 43. The workman by means of the handle 49 can swing the frame 50 so as to introduce the gatheringirons into the glass tank or pot and when the glass has been gathered thereon can withdraw them and swing them-out directly over the molds 4, into which the glass is dropped. The molds are between the position of the operator and the gathering-hole, so that no skill is required in filling them.

In operating the apparatus the gathering and feeding of one set of molds may be carried on while the glass is being pressed in another set, the operation thus going on continuously.

The advantages of my invention result from the doing away with the necessity for skilled labor and from the large output which may be obtained.

The tracks may extend in any desired direction, the molds may be returned on a higher or lower track instead of a track at one side, or overhead carriers may be provided for the molds, the gathering apparatus may be changed, and many other variations may be made in the form and arrangement of the apparatus within the scope of my invention.
