SPECIFICATION forming part of Letters Patent No. 696,806, dated April 1, 1902.

Application filed February 11, 1902. Serial No. 93,493. (No model- To (1.5/1 whom, 211; may concern:

Be it known that I, PHILIP T. DODGE, of WVashington, District of Columbia, have invented anew and useful Improvement in Linotype-Machines, of which the following is a specification.

In commercial linotype machines of the present day-snch, for example, as the Mergenthaler machine of the general organization represented in Letters Patent No. 557,000-the letter-matrices are discharged successively from a magazine to an inclined carrier-belt, by which they are delivered into an assembleror composing device, expansible spacers or justifying devices being delivered into the line at intervals from a magazine above the assembler. When operated by an expert the machine delivers the matrices and the spacers in very rapid succession, two, three, or more matrices being commonly in the air at one time on their way to the assembler. It is therefore necessary that the spacers should be delivered quickly and that the interval between their release and their entry into the line of matrices shall be accurately regulated with reference to the speed of the matrices, as otherwise they will enter improp: erly ahead of or behind a given matrix. Experience has developed the fact that under varying conditions it is desirable to vary the time consumed in the passage of the spacers from their magazine to the line.

My invention is designed to secure a variation in this time at will; and to this end it consists in a magazine for the spacers or justifiers so mounted that its distance from the assembler or place of composition may be increased or diminished at will.

The invention also consists in improve ments in the finger-key mechanism for operating the matrix-delivering devices.

As the other parts of the machine may be of any ordinary orapproved construction, the drawings herein are confined to those parts immediately associated with my invention.

Referring to the drawings, Figure 1 represents a front elevation of the. composing or assembling mechanism of a linotype-machine with my improvements incorporated therein.

Fig. 2 is an edge View of the same. Fig. 3 is a cross-section on the line 3 3 of the preceding figures. Fig. 4 is a detail.

Referring to the drawings, A represents the rigid main frame; B, the inclined magazine, from the lower end of which the matrices are delivered one at a time; Or, the vertical guides or channels through which the released matrices descend; II, the inclined carrier-belt to which they are delivered, and I the assembler or composing device in which the matrices are received and assembled in line side by side.

K represents the magazine for the wedge spacers or justifiers, located with its delivery side directly above the assembler I, so that as the spacers are released they will fall one at a time into the assembler direetlybehind the last matrix therein.

In their general construction and arrangement theforegoing parts are the same as those indicated by like lettersin Patent No. 557,000.

Heretofore the magazine K has been secured immovably in position on the frame, so that the same time is required under allconditions for the passage of the spacers therefrom to the composed line. I now mount this box, as shown particularly in Figs. 1, 2, and 3, so that it may be moved upward and downward on the frame at the Willot the attendant. It may be connected in any manner which will permit this adjustment; but I recommend the fitting of its supporting arm or bracket into a groove in the main frame, as shown in section in Fig. 3, with a bindingscrew L extended through the slot from the back into the bracket, so that in order to effect the vertical adjustment it is only necessary to loosen the screw, move the magazine as required, and then tighten the screw. By thus raising and lowering the magazine K and changing the distance between it and the assembler I am enabled to give a longer or shorter interval to the passage of the spacers to the line.

The spacers M, of the form generally used in linotype-machines of the present day, are suspended by ears at their upper ends on the inclined side walls of the magazine K, as plainly shown in Figs. 1 and 2, and they are released, as usual, by lifting them one at a time until their ears rise above the retaininglips at the front of the magazine, whereupon they pass down one at a time through the intermediate guide or channel to the assembler. The lifting is effected, as shown in the several figures, by arms m, carried by a horizontal rock-shaft N, actuated by an arm 0, secured thereto and receiving motion in its turn from a vertical bar or reed P, connecting with the keyboard. This rod P is connected to arm 0 by a-binding-screw Q, so that the point of connection may be varied according to the vertical adjustment of the magazine.

For the purpose of imparting motion to the bar or reed P, I extend the same downward in guides, as shown in Fig. 2, and terminate it just above the free end of a vertical pulleyvibrating yoke R, pivoted at r. This yoke is slotted to receive a cam S, mounted therein on a pivot and lying directly over a continuously-revolving roll T. The cam by reason of its eccentricity has a tendency to turn down into engagement with the roll; but it is held normally out of engagement by a fixed stop U, which engages the periphery of the cam, and by a dog V, which normally sustains the end of the cam-supporting yoke, so that the cam is held in an elevated position, as shown.

The dog V,ofangular form,is pivoted in the fixed frame and engages at its opposite end the rear extremity of the finger-key W, fulcrumed at w midway of its length.

The rear end of the yoke R is cut away slightly in the rear of the point at which the sustaining-dog V bears thereunder. When, therefore, the finger-key is depressed at the front end, it acts directly on the dog V, causing its upper end to swing rearward under the cut-away portion of the yoke B. This permits the yoke to fall until the cam S is disengaged from the stop U and engaged with the roller T, whereupon the friction of the latter causes a rotation of the cam, which being sustained by the roller acts to lift the yoke R above its original position, thereby actuating the rod P and causing it to effect the discharge of a spacer M from the magazine K. During this action of the parts the dog V beingreleased from the action of the finger-key resumes its original position to arrest the descending yoke, the action being insured by a spring W, which depresses the rear end of the finger-key.

As regards the cam, its yoke, and the roller thereunder, the parts are similar to those used in the ordinary Mergenthaler machine; but they differ therefrom in that the sustainingdogs V are arranged to directly engage the yoke at one end and the finger-key at the opposite end, thus doing away with the connections heretofore employed between the fingerkeys and the dogs. The present arrangement is not only simpler and cheaper, but has the advantage of being quicker and more responsive in action, so that speedy delivery of the spacers is insured. The same mechanism may of course be used for actuating the matrix-delivery escapements.

Having described my invention, what I claim is 1. In a linotype-machine, a magazine with spacing or justifying devices adjustable to and from the point of composition.

2. In a linotype-machine and in combination with the matrix-assembler thereunder, a magazine for the spacers adjustable vertically, whereby the time required for the passage of the spacers to the line may be varied.

3. In a linotype-machine and in combination with an assembler wherein the matrices I are composed or assembled in line, a magazine from which the spacers or justifiers are 1 delivered to the line, means for adjusting said PHILIP T. DODGE.
