SWINGING TABLE FOR HYDRAULIC PRESSES.

SPEDIFIGATION forming part of Letters Patent N 0. 709,285, dated September 16, 1902.

Application filed May 24, 1902. Serial No. 108,801. (No model.)

To all whom, it may concern/.

Be it known that MOSES WILKES, deceased, late a citizen of the United States, and a resident of Trenton, in the county of Mercer and 5 State ofNew Jersey, did inventa new and usefnl Improvement in Swinging Tables for Hydraulic Presses, of which the following is a specification.

The invention relates to certain new and I0 useful improvements inhydraulic presses used in vulcanizingrubber products.

In the use of vulcanizing-presses the molds are prepared and placed between the platens and then subjected to heat and pressure in the ordinary and well-known manner, and many and varied forms of presses have been devised and are in practical use; but in all cases the molds are prepared upon suitable tables or supports apart or away from the press, and after due and proper vulcanization has taken place the molds have to be carried from the press to the receiving table and there opened or discharged and new molds then again carried from the table or support to the press, involving considerable labor and loss of time.

The object of the present invention is to provide the vulcanizing-press with one or a series of swinging tables, accordingly as one or more platens are used in the press, and so that the molds may be prepared adjacent to the press and moved into position to be inserted under the platens, and after proper vulcanization has been had the molds may 5 be drawn out upon the tables and swung away from the front of the press and fresh molds readily inserted.

With these ends in view theinvention consists of the combination, with a vulcanizing- 40 press, of one or more swinging tables'vibratively connected with the press, whereby the molds supported upon the table may be brought into position to be expeditiously located under the platens and likewise may be removed from the platens and readily moved away from the front of the press in order that other or fresh molds may be inserted.

The invention also consists in the details of construction and arrangement hereinafter explained and specifically claimed.

In order that those skilled in the art to which the invention appertains may know how to make and use the same and fully understand its advantages, it will be described with reference to the accompanying drawings, in which Figure 1 represents a hydraulic vulcanizing-press of the most approved construction with the swinging tables constituting the subject of the presentinvention applied thereto. Fig. 2 represents a detachable frame which is secured to the press and which constitutes the'pivotal supports for the swinging tables, and Fig. 3 is a perspective view of one of the swinging tables and showing strenglheningribs on the under side thereof.

Similar letters of reference denote like parts in the several figures of the drawings.

A represents the foundation of the press, composed of suitable masonry, upon which the base B of the press is located and suitably anchored.

G represents the corner pillars or posts connecting the base B and the head D, secured together by suitable screw-threads and nuts E in an obvious and well-known manner.

F illustrates platens for compressing the molds, and any suitable or well-known means are employed for subjecting the molds to the action of heat, all of which need not be here described, as the invention relates only to the combination, with the press, of swinging tables.

G represents horizontal links or arms, the inner ends of which are passed over the ends of the corner pillars or posts 0 and rigidly secured in place by the nuts E. The outer ends of the links or arms G are located upon shouldered ends of vertical cylindrical rods H, and transverse brace-bars I are also passed upon the ends of the vertical rods H, thus constituting a frame for the support of swinging tables J, formed with a boss K at the inner corner and with radial strengthening or stiffening ribs L. The bosses are formed with a channel M, through which the vertical rods pass, and adjustable collars N on the rods H are secured thereto by set-screws O and located beneath the bosses K of the tables, thus constituting adjustable supports [00 for said tables. In the drawings there are illustrated three tables thus connected with each of the-vertical rods H, and the several tables are so adjusted vertically that two tables (one on each side of the front of the press) occupy the same plane with each of the platens F when in their open or separated condition.

From the construction shown it will be seen that when the platen is open or in its lowest position to receive a mold said mold being upon one of the tables in the same horizontal plane with the platen is brought to the front of the press by swinging said table into the position illustrated by the lowermost table at Fig. 1, and when a series of molds are to be subjected to the action of the press at the same time a corresponding number of tables are swunginto the position described with the molds upon, and the molds are then forced by hand or otherwise off of the tables and onto theplatens, and, if desirable, the molds may be located upon metal plates disposed upon the upper surfaces of the tables and said plates may be forced with the molds onto the platens. The tables so used to introduce the molds into the press are allowed to remain in front of their respective platens, and during the period of time the molds are being subjected to pressure and heat those tables occupying the open or outer position may be used to prepare additional molds for subsequent action by the press, and when the first molds are ready to be unloaded or withdrawn from the press they are drawn upon the tables in front of the platens, and such tables are then swung outwardly and away from the press, and the correspondingly-adjnsted tables upon which fresh molds are supported are then swung inwardly to bring such molds into position to be introduced into the press, as already described. From what has been explained it will be seen that the operator is enabled to keep his press constantly in use, for as soon as one tableful of molds is vulcanized another tableful is ready and can be expeditiously introduced to the press.

While the improved swinging tables are shown as applied to a vulcanizing-press, it will be understood that the invention is not limited to any particular press or for any particular purpose, as they may be advantageously used in connection with any and all kinds of presses used for various purposes, and while the tables are shown and described as connected to a specially-constructed framework attached in a simple and economic manner to the pillars or posts of the press they may be connected by other means in such manner as to be capable of proper adjustment and capable of the necessary lateral swinging movement.

Having described the construction, operation, and advantages of the improved swinging-table attachment for presses, what is claimed as new, and desired to be secured by Letters Patent, isp 1. In combination with a vulcanizing-press and vertically movable platens connected therewith, one or more horizontal tables vibratively connected with the vertical frame of the press and in alinement with the space or spaces between the platens, whereby molds may be delivered from the table or tables, to the action of the platens, or removed from the platens to the table, substantially as hereinbefore set forth.

2. In combination with a press, one or more laterally-swinging and vertically-adjustable tables adapted to support and transport molds to and from the press, substantially as hereinbefore set forth.

3. In combination with a press and the pillars or posts thereof, the links or arms'G,bracebars I, vertical rods H, and adjustable swinging tables J, substantially as and for the purposes set forth.

4. In combination with a press, a series of swinging tables arranged in pairs on opposite sides, each pair adapted to swingin the same horizontal plane, substantially as and for the purposes set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
