LlNoTYPE-MAoHlNE.

SPECIFICATION forming part of Letters Patent No. 756,477, dated April 5, 1904. Application led November 11, 1903. Serial N0- 180,756. (No model.)

To all whom, tm/ty concern:

Beit known that I, JOHN MACAULEYCOONEY, of Racine, county of Racine, and State of Wisconsin, have invented a new and useful Improvement in Linotype-Machines, of which the following' is a specication.

This invention has reference more especially to mechanism used in the Mergenthaler linotype-machine for effecting the delivery of the individual matrices from the magazine in the order in which they are to be temporarily assembled.

The mechanism used in the commercial linotype-machine is of the general construction represented in United States Letters Patent, No. 530,931, to Philip T. Dodge. It includes as elements vertical escapement actuating rods which are pulled downward by springs and individually lifted by underlying yokes carrying small cams which ride on rubber rolls beneath them. The machines are so constructed that the upper ends of the rods may be drawn backward out of engagement with the escapements in order to permit the removal of the magazine and the substitution of another carrying a different font or set of matrices. Preparatory to the disengagement of the rods it is desirable to support them and their actuating-yokes in an elevated position, so that they may be readily engaged with the escapements of the second magazine after it is placed in position.

My invention consists in means embodied in and forming part of the machine and common to the series of yokes and rods whereby they may be instantly supported and instantly released again when they are to be brought into action.

While I have represented in the accompanying drawings a construction which is found in practice to answer its purpose, it is to be understood that I believe myself to be the first to incorporate in a linotype-machine mechanism for instantly supporting or releasing the series of escapement-actuating devices and that the details may be widely modified without passing beyond thescope of my invention.

In the accompanying drawings I have shown my improvement as applied to the commercial Mergenthaler mechanism.

Figure l represents a vertical cross-section through the linotype mechanism with my improvement embodied therein, the parts being in operative position. Fig. 2 is a similar View of the parts with the cam-yokes and rods locked in their elevated or inoperative position. Fig. 3 is a side view of the yoke-guides with my supporting devices incorporated therein. Fig. A is a horizontal section on the line 4 4 of Fig. 3 looking downward. Fig. 5 is a perspective view showing the parts separated from each other. Fig.- 6 is an end elevation of a series of matrix-yokes with the supporting-plate sustaining them in elevated position.

Referring to the drawings, A represents the inclined magazine, having' longitudinal channels to guide the gravitating matrices B, the escapement of which is controlled by the centrally-pivoted escapement-levers C, having at opposite ends dogs or pawls which are alter-` nately projected upward through' the bottom of the magazine. There is an escapement for each magazine-channel and its row of contained matrices. A spring D acts on each escapement and tends to retract the lower dog to permit the escape of the foremost matrix from the magazine. To each escapement there is hooked the upper end of a vertically-guided rod E, urged constantly downward by a spring e of suflicient strength to overcome the spring I), and thereby hold the lower escapementpawl normally Vin the elevated position, as shown. The bars E are guided in the main frame, and the upper guide E is movable horizontally to permit the disengagement of the series of rods when the magazine is to be removed 'from the machine.

F F represent a series of horizontal yokes supported at their outer ends on horizontal pivots f and arranged at their inner verticallyswinging ends beneath the respective rods E. Each yoke is slotted vertically to receive the cam or eccentric J, mounted on a horizontal pivot therein.

K represents a constantly-rotating roll pressed, the dog Gr is caused to release the yoke F, which falls until its cam J disengages from the stop-pin L and bears upon the roll K, from which it receives rotary motion by reason of the frictional engagement between their peripheries. As the cam rotates its eccentricity causes it to push the yoke F upward above its original position until it lifts the rod E, so as to reverse the position of the escapement and release the matrix. The iinger-key being instantly released, the dog Gr resumes its first position and arrests the descending yoke at its original height. The cam J being heavier on one side than the other continues to turn forward until it is arrested by the stop-pin in its original position and out of engagement with the roll. In order to prevent the crowding of the parts, the yokes are arranged in two series, right and left, to engage the alternate rods E. Allof theforegoing parts are constructed and operate as usual and form no part of my invention.

The aim of my invention is to give support to the yokes F and rods E in their normal positions of rest or at a slightly higher level. For this purpose I.propose to extend beneath the rising and falling ends of the yokes a lifting or supporting device of any suitablecharacter adapted to sustain vthe series of yokes and the rods bearing thereon.

In the form shown the support consists of two horizontally-movable plates M, extended one beneath each roll or series of yokes.

Fach plate is seated or supported in the frame 1 and is provided in the upper edge with a series of vertical slots in which the ends of-the yokes play when they are in action and between the slots with a series of fingers m, the upper ends of which are beveled or inclined, so that when the plates are moved endwise from their normal position they will act beneath the series of yokes and give the latter and the rods resting upon them the requisite support, as shown in Figs. 2 and 5.

, -In the commercial machine and` `n order to avoid interference with the other parts I employ two plates M, one for the front and the other for the rear series of yokes, and I connect these plates at one-end to a horizontal Operating-bar m2, the outer end of which is slotted transversely to receive a crank-pin on the upper end of a vertical rock-shaft m3,

which is supported in a bracket or plate m5, fixed to the main frame. The lower end of this rock-shaft is provided with an operatingliandle m6. By moving this handle in one direction both supporting-plates are drawn endwise and their teeth presented beneath .the yokes to give the yokes and rods the requisite support. When the handle is moved in the opposite direction,both plates M are shifted endwise and the yokes released, so that the machine may operate in the usual manner.

The employment of a plate or lifting device remaining permanently in the machine and adapted for adjustment to instantly support or release the series of escapement actuatingrods constitutes the essence of my invention. While itL is preferred to have the supports act through the yokes, the only essential requirement is that they shall give support to the escapement-rods, as these are the parts which require to be maintained in the ,elevated position.

It will be observed that my mechanism is adapted in and of itself and without manual assistance to sustain the rods in an elevated position. In this respect it is to be distinguished from manual devices for lifting the rods, by which the rods are sustained only so long as the parts are held in position by the attendant.

Having thus described my invention, what I claim is! l. In a linotype-machine and in combination with a series of cam-yokes, an adjustable mechanism mounted in the machine for the purpose of sustaining said yokes in inoperative positions.
