TYPE-CASTING MACHINE.

Specification of Letters Patent.

Patented Mar. 21, rain.

Application filed. October 13, 1915. Serial No. 55,660.

. the molds of type casting machines and has reference to molds for casting single types whether of that character where the mold is carried by a swinging frame or slide and opens and closes respectively as themold recedes from or approaches the casting spout, or of the character where the mold parts slide relatively one to the other to open and discharge the cast types and close fora fresh castingoperation.

The object of my present invention is to -provide means whereby a single adjustable mold composed of two main L-shaped parts can be employed for all body sizes of type and adjustment for set width is also provided.

Another object is to provide for the easy detachment of the breaks or tangs, while a further object of the invention is to provide means whereby the same molds which are employed for casting character types can also be employed for casting space types.

My invention is illustrated in the accompanying drawings wherein:

Figure 1 is a rear elevational view of the molds of my machine in the closed position. Fig. 2 is a front sectional elevation of the molds shown in Fig. 1 from the opposite side. Fig. 3 is a sectional view on line A-A of Fig. 2. Fig. 4 is a partial sectional view illustrating the mold after the type has been cast and the mold has commenced to open. Fig. 5 is a perspective view of one form of complete cast type together with its tang or break.

Referring to these drawings and particir larly to Figs. 1 to 5 the numeral 1 designates the swinging frame which carries the upper L-shaped mold part, 'and the numeral 2 designates the stationary support for the lower L-shaped mold part. The upper mold part consists of a block 3 in which a vertically adjustable member 4 is slidably mounted and the lower mold part consists of a horizontally slidable block 5 carrying a vertically adjustable member 6. To adjust for body size either the member t is adjusted to the'member 6 by means of the adjusting screw 7 or the member 6 may be adjusted up to the member l. That is to say, one of the members 4 or 6 is set to the correct position to give the desired body size, which can be determined by means of a gage piece 8, and the other member is then adjusted to it. To adjust for set width the block 5 is adjusted horizontally by means of the screw 9, and of course carries with itthe member 6. When the mold is once adjusted it will be seen that it consists of two composite L-shaped parts, one of the composite parts being formed by the members 3 and a and the other of the composite parts being formed by the members 5' and 6. ltwill be seen that the parts 4: and 6 can be adjusted in the parts 3 and 5 so that in the views such as Fig. 2 the composite parts will appear L-shaped. The front ofthe mold is closed by the tang or break mold 10 and the rear of the mold is closed by the matrix 11 in the usual manner.

The operation of the machine is similar to that of an ordinary Titchener machine. That is to say, after the casting operation the matrix and casting spout move away and the upper part of, the mould swings up about the hinge 12. The type is carried up until its extremitiesthe character at one end and projection left upon the end of the breakcome into contact with some fixed obstructions on the machine and the cast type is'thus knocked out of the mold and falls down and slides off the lower mold part, the whole mold being arranged upon an incline as shown in Fig. 4- for this purpose. If this operation is performed, however, in the usual manner, the cast types will still have the tangs or break attached to them and they will have to be removed by hand as is usual. I propose howeverand it is an important feature of my inventionto automatically remove the breaks before the cast types are released. To accomplish this I provide the upper part of the break mold with an undercut recess 14 so that the types are cast with a projection 15. As the upper mold part rises, this projection holds the type locked to the upper mold part, and I arrange an obstacle 16 which abuts against the end of the spring controlled spindle 18 which is restricted to a very limited movement by means of the fixed memher 19 as is clearly shown in Fig. 3. This obstruction l6 is so placed that the type first comes" into engagement with it at its character end and this serves to. detach the type from its break-seeing that the break is still locked to the mold by the projection 15and the type falls away in the usual manner. The falling type is indicated at 'I in Fig. 4. The upper mold part continues its opening movement until the projection 15 of the break which is still locked to the mold part engages an inclined obstruction indicated by the numeral 16 and the break is thus pushed sidewise to insure the disengagement of the projection 15 from the recess 14. The break thus falls away and the mold closes for the next operation. It will be noticed upon reference to Fig. 5 that the nick 17 is cast in the top of the type and the break is arranged at the bottom to facilitate the detachment of the break from the type. The severance of the break usually leaves a bur at the foot of the type which usually has to be filed off by hand.

Having thus described my invention, I claim- 1. A mold for type casting machines comprising two L- haped halves each consisting of two relatively adjustable members, means for adjusting these members whereby the area of the mold cavity can be adjusted, and means whereby the typeis cast with a projection on its tang by means of which it is locked to the upper mold part.

2. In a type casting machine, an upper composite L-shaped mold part, a lower composite L-shaped mold part, a hinged frame carrying said upper mold part, means whereby the type is cast with a projection on its of the mold cavity, at least one of the blocks being L shaped, means whereby relative movement of said blocks may be produced to close and open the mold, two auxiliary blocks carried by said blocks forming two sides or" the mold cavity and adjustable in the direction of the opening and closing movement'of said first mentioned blocks, and 'means whereby relative adjustment of said first mentioned blocks may be made in a direction at right angles to the'opening and closing movement.

4. A mold for type casting machines com-V prising two complete L shaped halves in closing a mold cavity of rectangular or cross section, and means whereby said halves may be adjusted to alter the cross section of said cavity in each of two directions at right angles to each other.

In testimony whereof I afiix my signature in presence of two witnesses.
