NITED j STATES 'y PATENT @FFI-CE.
WILLIAM FILMER, OF SAN FRANCISCO, CALIFORNIA.'
IMPROVEMENT vIlil APPARATUS FOR CASTING'APRINT-E'RS LEA-DS.
Specification forming part of Letters'Patent No. 142,783,
April 17, 1873.
To all whom it may concern:
Bc it known that I, WILLIAM IFILMER, of
San-Francisco city and county, State of Caliv ther invention or experiment.
Heretofore printers leads have been cast longitudinally in hand-molds by a slow and tedious process, the metal being poured into the end of the mold, thus rendering it impossible to cast them more than eight or nine inchesin length on account ofthe metal becoming cool in the mold, and even then they are seldom uniform.
My invention consists in combining a furnace, metal-tank, dipper, and mold, in such a manner that the leads can be cast in a uniform manner any desired length and with great facility.
In order to more fully illustrate and explain my invention, reference is had to the accompanying drawing forming a part of this specitication, in which* Y Figure l is a sectional elevation of my machine. Fig. 2 is a side elevation. Fig. 3 is a plan view. Fig. 4 is an enlarged back view yof the dipper. Fig. 5 is an enlarged section 0i' the mold opened. Fig. 6 is an enlarged front view of the plate G. Fig. 7 is an enlarged View of the bar M. i l
A represents a furnace, and B a metal pot or tank, which is placed over it, and in which the type-metal is placed to be melted. C is the mold-stand, which is conveniently secured to the base or platform D, so as to support the mold in the proper osition with reference tothe pot or tank B. is an inclined bedplate, which is supported upon the stand O by the triangular supports f f at the desired angle. This bed-plate serves as a support for the mold. -The mold consists of two parts, Gr la., the partG being simply-a metal plate hav-v ing a ledge, i, extending around its lower edge and two side edges, while its upper edge is turned outward. The ledge t is intended to dated September 1G, 1873; application filed be of the same thicknesses the 'leads to lbe cast. A layer, j, of paper, or some other nonconducting substance, is interposed between the backv of the plate G and the bed-plate,lso as to prevent the heat from passing through to the bed-plate. K is the movable part of the mold, and consists of a plate which is hinged to the triangular supports ff, so that it can be closed down upon the part G ofthe mold. The plate k is placed against the inner face of the hinged plate K, so that when the plate K is turned down upon the part G of the moldit will rest upon the ledge i and forma tight joint, while the. space between these two plates forms the lead-mold. The upper edge lof the plate h is turned outward in an opposite direction from the edgef the plate G, the two edges thus brought together forming a flaring mouth, into which the metal is poured Misa brace, rod, or bar, which is secured longitudinally, in staples o, to the outside of thehinged part of the mold. A hook, fn, is secured to the triangular supports f, at each end of the mold, which can be hooked over the ends of the bar M, and setscrews p p pass through the bar, so as to press the parts of the mold firmly .together while the metal is being poured. R is what I call a dipper, and it consists of a broad plate having shallow sides and slightly convex bottom,`
Fig. 4. This dipper is hung upon a shaft, S, over the edge of the tank B, being suspended so that a greater portion of the dipper is inA side of the tank. The inside end of the dip! per is curved upward, and holes t t are made between the edge and curve, through which the molten metal will pass into theV dipper, when theupward-turned end has been lowered into 'the metal sufficiently, thus taking the metal into the dipper from below the surface without disturbing, or drawing oli' the scum which always floats on top ofthe metal. The opposite side or edge of the dipper iscovered by a plate, u, which extends a short distance back from its edge, so as to form a long slotted opening, through which the metal is poured.
-The moldis loca-ted in sucha position .that by tipping the dipper outward, after it has been charged with metal, by means-of a lever, c, secured to the ends ofthe shaft `S, theslot'- ted opening will be brought directly over the A flaring mouth of the mold, so that the metal can pass in between the plates G h, where the lead is cast.
By constructing the mold in the manner above described, the leads can be cast of any desired length, and with perfect uniformity.
Sheets or plates can be cast nine or ten inches in width and of the desired length, and
i afterward be cut into strips to form the leads.
Having thus described my invention, what AI claim, and desire to secure by Letters Patent, is-
1. Ihe furnace A and pot B, with its tilting dipper R, in combination witha lead-mold, when arranged in relation to each other substantially as above described.
2. The dipper It, `provided with the filling-v holes t t, when suspended upon a shaft, S, and
operated by the lever v, substantially as and for the purpose above described. 3. The frame consisting of the inclined bedplate E, hinged side K, bracebar M, hooks n, y and set-screws p p, in combination with the' removable moldplates G h, with their flaring outer edges and the tilting dipper R, all comi bined and arranged to operate substantially as and for the purpose above described.
In witness whereof I vhereunto `set my handl and seal.
