JOHN FLEMING, OF TORONTO, ONTARIO, CANADA.

MACHINE FOR CASTING PRINTERS LEADS.

SPECIFICATION formingpart of Letters Patent No. 233,608, dated October 26, 1880.

Application filed May 12, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN FLEMING, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, manufacturer, have invented certain new and useful Improvements in Machines for Oastin g Leads for Printers Use, of which the following is an exact description.

My invention relates to machines for easting printers leads; and it consists in certain improvements therein, hereinafter more fully set forth.

Referring to the accompanying drawings, Figures 1 and 2 are cross-sections of a machine for casting leads in the construction of which my improvements are embodied. Fig. 3is a plan, and Fig. at an end, view of the same. Fig.5 is a perspective in detail of the lead-gate.

The apparatus consists of a flask, A, made in two sections, A and A which are coupled together at their-lower ends by a slotted hingejoint, a. p

The base-plate A of the flask is provided with a clam ping device, B, by which the plates are clamped together when the lead-gate O is placed between for casting, and in order that the plates of the flask may be separated to permit of the removal of the lead-gate the beam B of the clamp is made adjustable and is provided with a screw, B

The flask is provided with central journals, b, mounted in journal-bearings d 61 upon a frame, D, in such manner that the flask can be turned to and supported in either of the positions shown in Figs. 1 and 2.

The 1ead-gate O is provided with a series of parallel longitudinal openings, 0, which correspond in width with the lead in the rough, and care is taken to make the gate of a uniform thickness throughout its surface.

The inner faces of the flask-sections are covered with a layer of asbestus, paper, or other material, which will prevent the melted material of the leads cooling before it reaches the bottom of the openings 0.

In operation the lead-gate is inserted between the sections of the flask, and the flask clamped up and placed in the position shown in Fig. 1. The melted composition of which 0 the gate in a most perfect manner. So soon as 5 5 the metal is cool enough the flask is tilted in the position shown in Fig. 2, and the gate removed by unfastening the clamp.

After the leads and slugs are thus cast in parallel bars of approximately the proper width and thickness, they are placed in a planing-machine and finished and cut up in the ordinary way to the standard sizes required.

The advantages of my invention are rapidity and economy in the production of leads and slugs by the saving of labor and time.

I claim as new and desire to secure by Letters Patent- The combination, with the swinging flask A, provided with central journals, 1), and composed of the two sections A A coupled to gether by the slotted hinged joint a, of the frame D, having journal-bearin gs d d, clamping device B, attachedto the lower section, A and provided with the beam B B and leadgate 0, having a series of longitudinal openings, 0, substantially as described, and for the purpose set forth.
