Title: Improvements in Printing Type and Method of and Apparatus for Making the same.
Inventor: SMITH JOHN JOSEPH CHARLES
Filed: 1897-10-08
Granted: 1897-11-27
Abstract: 23,142. Smith, J. J. C. Oct. 8. Type. - Consists in casting ordinary small printing-type of bronze or hard alloy, and of a method of and means for casting such type. A pattern is made consisting of a bar A,.Fig. 4, with facsimiles of the types attached to and projecting from one edge after the manner of the teeth of a comb. This pattern is then fixed d in a flask B, Fig. 2a, consisting of two parts 6, which can be fixed together by screws 25. A composition of plaster of Paris and fine asbestos pulp, as described in Specification No. 2629, A.D. 1894, is then run in to form a mould C, which is removed from the flask with the pattern A therein as shown in Fig. 4. The pattern is then carefully drawn out of the mould by an apparatus having a screwoperated slide which engages the two edges of the mould on each side of the projecting part of the pattern A, and when moved by the screw pushes the mould off the pattern. The moulds are then dried in an oven at a gradually-increasing temperature. A number of these moulds are locked up in parallel series in a frame, at one end of which is a block of the same material as the moulds, having gates leading to each mould. Between each two moulds is placed a smooth brass plate or strip. The series of moulds is covered by a slab, preferably of the same material as the moulds, in which is a passage leading to the passages in the gate block. The casting-apparatus is shown in Fig. 11. The frame containing a series of moulds .is placed against a front plate 36, against which it is pressed by a follower 42 operated by screws 41. The screws work in cross-bars 40 hooked to or engaged with side plates 38 hinged to the sides of the front plate 36. The molten metal is run into a receptacle 43, hinged at 44, and provided with a refractory lining 46 of asbestos. A plunger 47 is then forced into the receptacle 43 by a rack and pinion 49 operated by a lever 50. The pressure on the metal causes it to break through the lining 46, and it is then forced through the passage 35 and on into the moulds. The castings, Fig. 12, after removal from the moulds, are placed in a mould, and soft metal is run in so as to fill up the spaces between the types 52. This strengthens the casting while the grooves or nicks are cut in the edges of the types, and while the types are cut off from the bar G connecting them.
