SPACE CASTING MECHANISM OF TYPOGRAPHIG MACHINES. APPLICATION min ocT. i2, 192;).

Specification of Letters Patent.
Patented Feb. 21, 19232.
Application filed. October 12, 1920. Serial No. 416,530,
avith spaces of the same length as the type less the depth of strike, a very slight longitudinal displacement of the spaces renders them liable to receixe ink and to make an impression on the paper and it has been pro posed to obviate this by reducingthe length of such spaces subsequent to the casting operation or by casting the spaces shorter than the type by means of a differential body slide in the type mould.
The latter plan, which has been used in mechanically controlled automatic type casting machines, is applied according to the present invention to ty ographic machines of the kind in which the matricesare assembled in line by means of keyboard mechanism and then pass successively to the casting mechanism, by making the bottom oi the set notch in the edge oi? the matrix stopped, the shallower step serving to determine the correct set width, while the deeper step onables a differential mould blade to cut oii the front part of the mould aperture.
The invention will be more specifically dc scribed with reference to the accompanying drawings, wherein Fig. 1 is a front elevation of the mould and movable blade slides;
' Fig. 2 is a plan view of same with top mould block removed; and
Fig. 3 is a perspective detail showing the V the set notch of the matrix ol when the latter is clamped on the mould substantially as described in British Patent Specification No. 1903 of 1000. In the case of a character or a type-high space the bottom of the set notch of the matrix is in one plane and the casting ends a 6 (Fig. 3) of the blades are in alignment at the moment of casting, the metal being injected into the mould against the face of the matrix.
If, however, a low space is required, the set notch oi" the matrix is stopped, as shown at (Z (Z the shallower step (Z against which the lug c on the main part a of the mould blade abuts serving to determine the correct set'width, while the deeper step 0Z permits the auxiliary blade Z) to move forward so as to cut o1f the front part of the mould aperture. In this case the metal is injected against the auxiliary blade and a shortened casting produced.
Having thus described the nature of the said invention and the best means we know of carrying the same into practical effect, we claim r 1. In typographic machines wherein the matrices are assembled in line by means of keyboard mechanism and then pass successively to the casting mechanism, space casting mechanism comprising a space matrix having a stepped set notch therein, and a mould blade in two parts relatively movable to each other and cooperating with the re spective steps of the set notch, one step serving' to determine the correct set width, while the other step determines the height or length of the cast space.
2. In space casting mechanism as claimed in Claim 1, a mould blade in two parts capable of independent movement and having projecting lugs adjacent to their casting ends arranged vertically one over the other and space matrix having a stepped set notch with which the said projecting lugs and the differential movable blade are adapted to engage when the matrix is clamped in the mould.
In testimony whereof we have signed our names to this specification.
