APPARATUS Foe CASTING LEAD SEALS.-

SPECIPICATION forming part of Letters Patent No. 375,313, dated December 20, 1887.

Application filed September 14, 1857. Serial No. 249,704.

To all whom it mag concern.-

Be it known that I, TIMOTHY GoNNERs, a citizen of the United States, residing at Portland, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Apparatus for Oasting Lead Seals, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for casting lead seals, and more particularly that class of lead seals in which are used two holes extending lengthwise of the seal for the reception of the two ends of the sealing-wire.

By way of explanation it may be here remarked that the device designed to be made by this apparatus is variously termed a baggage-seal,, or, more generically, a lead seal.

The uses of such seals are numerous; but it is proper to say that they are perhaps most largely used for sealing railroad-car doors containing goods in transit.

The invention consists in a sealeasting apparatus having a stationary flask in which the pattern is reproduced many times, the bottoms of the molds containing ejectors, which are arthe casts from the flask, combined with pivoted gate or sprue containing members, which carry core-pins for making the wire-holes in the leads, and which members also serve to finish"the leads before they are discharged from the flask, the construction and operation being substantially as hereinafter more particularly set forth and claimed.

In the accompanying drawings, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view. Fig. 2 is an elevation of one end with the handles of the sprue-containing members in section. Fig. 3 is a side elevation with the casing in section; and Fig 4 isa vertical section, taken in the plane of line :20 a: of Fig. 3, showing the casing in dotted outline.

The apparatus is composed of two similar side pieces, a b, which may be arranged upon a suitable table or base, 0. These side pieces have, rigidly secured at their upper ends, a metal flask, d, in the upper surface of which are arranged the molds in any suitable numher.

(No model.)

ff are a number of disks, equal in number to the molds, which are arranged within and form the bottoms of said molds. These disks are mounted on posts 9, which are secured to a plate or bar, h, which plate or bar is supported upon springs i, suspended on rods 3', depending from the bottom of the flask d. Furthermore, the plate or bar It is connected to a lever, is, by a rod or link, Z, the said lever k being pivoted to the crossbar a of the frame a at one end, and provided at the other end with a locking-latch, an, adapted to engage the cross-bar b of the frame I). The plate or bar h is provided with temper screws or buffers n, which abut against the stationary flask d to limit the upward movement of the followers.

The disks f, constructed and arranged as just described, constitutewhat I have herein termed ejectors, their function being thus accurately described, as presently more particularly will appear.

It is to be observed that the springs i tend to elevate the plate h, and hence throw up the ejectors. The locking device m, for holding down the ejectors, may be simply a hook pendent from the free end of the lever 70, although any other convenient locking device may be employed.

The face of the flask d is made true and smooth, and to this face are pivoted, at 0, two bars, 1) p, which are provided with as many gates, p, as there are molds, and these several gates are connected by a gutter or sprue, p. l have herein designated these devices 19 10, thus constructed, as sprue or gate containing members, not only because they contain these features, but for the sake of giving them a short title. The end surfaces of these members are made true, so as to make a close joint or lit with the upper outer surface of the flask, and the edges of the gates p are made sufficiently sharp to sever the fin or neck of metal from them above the casts in the molds. In order to thus sever the casts from the metal in the gates or sprues, I provide the members 5 p at their free ends with pivoted cams q, having operating-handles q, and I arrange these cams to act against the surfaces q of the flask. (See the dotted lines in Fig. 1.) It is obvious that by throwing out the handles g from the flask mo the members p will be forced away from the flask, and thus serve to separate the casts in the molds from the metal in the said members p. The members 1 have right-angle flanges p, to which are atfixed core-pins 0-, two for each mold and intersecting said mold transversely. The web of metal d separating the two rows of molds is pierced transversely in alignment with the corepins to receive the points of said core-pins.

In order to withdraw the core-pins from the caste in the molds, the members p are rotated upon their pivots so as to clear the flask, and when this is done then the locking device on may be released, thus leaving the springs 5 free to act to throw up the plate It and enable the ejectors to throw out of the molds the casts or leads, which are then in condition for the reception of the wire.

The leads or casts may be discharged from the flask into the casing or box 8, which may be conveniently arranged to inclose the machine between its side frames and below the gate-containing members, and a door, 8, may be provided in the lower end of this boX or casing, through which the seals may be withdrawn.

It is within the spirit of this invention to use either one or two gate-containing membersp and any number of molds in the flask, and of course the ejector will correspond in number of disks with the number of molds. Moreover, the invention is not limited to the described precise form of the ejector.

It will be understood that any ejector is within the spirit ofmy invention which oper-,

ates quickly, as by the action of the springs i to throw out the casts, and which, in the event of the said springs failing, may be moved by the lever in, for example. For it will be understood that the springs i serve to project the ejectors when the locking device m is released, and it will be equally as well understood, should the springs fail to throw up the disks, that the lever k may be used to force them up.

. It will be also understood that this lever is is used to seat the disks in the bottoms of the molds when fresh casts are to be made, and that the said disks are held in this seated position by the locking device engaging the barb.

Vhat I claim is- 1. An apparatus for casting the leads of lead seals, comprising a flask, a sprue or gate containing member truly fitted to the face of said flask and pivoted thereto, so as to be movable crosswise of the face of said flask to shear the face of the cast, core-pins attached to the said gate-containing member, and an ejector arranged within the flask to discharge the cast from the mold therein, substantially as described.

2. In an apparatus for casting the leads of lead seals,aflnsk having series of molds therein, gate or sprue containing members pivoted to Said flask and truly fitted to the face thereof, core-pins attached to said gate containing members and entering the molds transversely, disks arranged in and forming the bottoms of said molds, a spring-pressed plate or bar to which said disks are connected, and a locking lever for operating said plate or bar and its attached disks, substantially as described.

3. In an apparatus for casting the leads of lead seals, a flask containing a suitable number of molds, a gate-containing member pivoted to said flask and containing a number of gates equal to that of the molds and closely fitted to the face of said flask, and the cam pivoted to the free end of said gate-containing member and bearing against the flask to effect the movement of the gate-containing member crosswise of the flask to dress the face of the cast or sever the surplus metal therefrom, substantially as set forth.

4. The flask (2, having a series of molds divided by a wall, d, combined with an ejector, a sprue or gate containing member pivoted to the flask and adapted to be moved crosswise over the top of the same, and having two corepins for each mold attached thereto and adapted to be projected crosswise of the molds with their ends extending into perforations in the wall d, substantially as described.

5. An apparatus for casting the leads of lead seals, consisting of the side pieces, a b, a flask, d, provided with any desired number of molds, secured to the upper ends of said side pieces, the gate-containing members pp, pivoted to said flask and provided with the cams q q, the core-pins 1', attached to said gate'containing members and piercing the molds transversely, and the ejector composed of the disksff, posts 7, plate or bar h, spring-supportst'j, and locking-lever in l m, and the casing s, all combined and arranged substantially as set forth.

In testimony whereof I have hereunto set my hand this 2d day of September, A. D. 1887.
