LIN'OTYPE-MACHINE.

Specification of Letters Patent.

Patented May 26, 1914'.

Application filed J'u1y 14, 1913. Serial No. 778,817.

To all whom it may concern Be it known that I, JAMES A. QUINN, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Linotype-Machines, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to linotype machines, and particularly to the type matrices of machines of this class. Heretofore, it has been customary to employ matrices in machines of this class having but two letters, but this invention involves matrices having three letters, and a corresponding change in the construction of'the machine whereby a great saving of time is accomplished and a corresponding saving in labor and expense.

The invention is fully disclosed in the following specification of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a vertical section on the line 1-1 of Fig. 2 through what is known as the vise and the first elevator of a linotype ma chine Fig. 2 a sectional plan view of the construction shown in Fig. 1 Fig. 3 a face view of the mold and mold plate of a machine of the class specified Fig. i a section on the line 4t of Fig. 3, and Fig.

5 a side view of a matrix made according to my invention, one of which is also shown in Fig. 4.

In the drawing forming a part, of the specification, I have shown at a the vise of a linotype machine, at Z) the first elevator. The elevator b is provided with a flat arm 6 which extends over the vise a and is provided with two screws 12 and I) passed vertically therethrough. The vise a is provided in the top surface thereof with a longitudinal groove a in which is placed a rail 0 which is movable longitudinally in said groove. Placed on the vise a is a stop (Z having a reduced extension d through which is passed a screw 03 which is also passed in the rail 0 and the stopd is movable with the rail 0. The vise a is also provided with the usual vertically movable safety stop 6, and secured to the rail 0 at a is a spring arm a provided with a blockshaped head (1. and said rail is also provided at one end with a pin a by which it may be moved back and forth in the vise a. All this construction is old and well known in machines of this class except the rail 0, the spring arma and the stop (Z which features constitute a part of my invention. I have also shown at f the mold of the machine, back of which is indicated in dot-ted lines the mold wheel 9. The mold f involves a back member h, a top member i and a front member 7' having three longitudinal grooves j 7' and j*, and this construction is also all old and well known except the groove j in the part jpf the mold. Between the parts it and z of the molds is the usual longitudinal space is in which are placed the usual blocks is and 72 which determine the length ofth slug to be cast. I have also shown at m, one of my improved matrices, and this device is the same as others of its class except that it is provided with three letters 777?, m and m. The letter m is an additional letter over those heretofore employed.

In the operation of casting the third letter ofmy improved three letter matrix, the machine is set for the usual duplex casting, or the casting of the second letter .and the rail 0, or what I call the additional three letter castrail, is thrown into the.position shown in dotted lines in Fig. 2, in which position the spring arm at and the stop d are not in engagement with the automatic stop e,-or a projecting member 6 respectively, and in the operation of the machine, or the downward movement of the first elevator, the letter at of the matrices will cast a third letter, or will be in the position shown in Fig. 4, and by the adding of the groove j, or by constructing a mold with three grooves, as shown at j 3' and j in Figs. 3 and 4, the above operation of casting a third letter will be made possible. It will be understood that the downward movement of the elevator Z) will be limited by the vise a, or the projecting member 72 thereof will bear on the face of said vise, and throwing the stop at out of engagement with the projecting member 6 will permit the usual matrix holder 6 indicated in dotted lines, in Fig. 1, or the matrices therein, to drop into the position shown in Fig. 4, or the three letter cast position. If the operator should desire to cast thesecond letter, or the letter at which the machine was first set, in the beginning of the operation, the three letter cast rail will be thrown into the position shown in full lines, and this operation is a great time saver, as will be readily understood, and has heretofore been impossible in the casting of one and two letters. In the casting of one or two letters, the rail 0 is always in the position shown in full lines.

The changes necessary on the present linotype machine to cast the third letter are as follows: The screw or stop 6 will be turned into the position shown in Fig. 1, so that it will not engage the vise as a stop, and the vise (Z will be provided with the rail 0, the spring arm (6* and the stop (Z, and the mold will be provided with three grooves f, j and j, as shown in Figs. 8 and at, and the matrix or matrices will be provided with an addi tional third letter face, as shown at m in Fig. 5.

In machines of the class referred to, that are now in use, the downward movement of the first elevator b is limited by the screws 5 and Z), and in my improved method of casting the third letter, the said screws are adjusted so as to cast the first and second letters of the matrix, when the stop (Z and spring ar'm (f are in line with the screws 6 and 6*, but when thrown out of alinement or engagement therewith, the downward movement of the first elevator Z) is limited by the projection b striking the face of the vise (Z which permits the casting of the third letter, and as hashereinbefore been stated, the matrices used in casting the third letter can be used to cast the second letter by simply returning the stop (Z and spring arm on the rail 0, into the first named position.

My invention is not limited to the exact details of the rail 0, stop (Z and spring arm herein shown and described, and changes in and modifications of these features of the construction may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is 1. In a linotype machine of the class described comprising the usual vise, first elevator and vertically movable safety stop, devices movable on said vise, a matrix provided with three type faces, and a mold provided with three grooves to permit of the casting of three type faces for said matrix by means of said devices in the operation of the machine.

2. In a linotype machine of the, class described, comprising the usual vise, first elevator and vertically movable safety stop, a matrix provided with three type faces, a mold provided with three grooves, av longitudinally movable rail mounted in said vise, a stop secured thereto, and a spring arm secured to said rail and operating in connection with said vertically movable stop, whereby said matrix and said mold may be placed in communication in the operation of the machine.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 7th day of July 1913.
