Application filed June 18, 1912. Serial No. 704,442.

and overthrow of motion between the escapement actuating mechanism and the escapements is provided for.

To these and other ends, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing: Figure 1 represents a vertical section through portions of the magazine, escapement actuating mechanism and keyboard showing the improvements of the present invention applied thereto, the mechanism being shown in normal or inoperative position; Fig. 2 is a view similar to Fig. 1 showing the escapement and its actuating mechanism in operated position.

' Similar parts are designated by the same reference characters in the several views.

The present invention is applicable generally to esca-pement mechanisms of different types, and it is to be understood that the invent-ion is not limited in this regard although the present improvements are shown in connection with an escapement of a novel form which forms the subject matter of a separate application and hence is not claimed herein.

The preferred embodiment of the invention is shown in the accompanying drawing and will be hereinafter described in detail, but it is to be understood that the invention is not limited to the particular construction shown, as equivalent means may be provided for accomplishing the same results.

i i 1 l will hereinafter appear.

In the present instance, 1 designates the 1 lower or. matrix delivery end of the magalzine, the magazine having a channel for each row of matrices 2, and the escapement 3, one of which is arrangedin the bottom of each matrix channel of the magazine, 1 controls the delivery of the matrices there from.

The escapement shown be briefly described as composed of a segmental ,member of substantially semi-circular form l and formlng dogs a and 5 at lts ends to cooperate with the ears or lugs 6 on the .matrices, each escapement being adapted to g oscillate about a fixed axis which is in sub ;stantial alinement with the ends of the esoapement and is located in the matrix guiding groove formed in the bottom or" the magazine channel. The escapement is supported and guided in its oscillatory movements by a segmental bar 7 which extends transversely across the bottom of the magazine and the escapement is returned auto- 1 mati'cally to initial position after each actuj atlon thereof by a spring 8 which bears on a lug 9 on the escapement and has its end fixed in a projection 10 which is rigidly attached to the magazine. A cover plate or guard 11 is also applied to the under side @of the magazine and coiiperates with the jouter side of the segmental e'scapement to retain the same'in cooperative relation with .the bar 7.

A lug 12 projecting from that end of the escapement opposite'to the end bearing the lug 9 serves to actuate the es- }capement in opposition to the'action of the spring 8, the two positions of the escape ment being indicated in F igs. 1 and 2.

1Preferaibly, the under side of the actuating lug 12 of the escapement is formed with a beveled surface 13 for a purpose that The key lever 14 may cooperate as usual with a vertically movable key bar 15, the latter cooperating with a bell-crank lever 16 the end 17 of which bears on and normally supports the cam yoke 18, the latter being fulcrumed on the machine frame at 19 and bearing a cam 20 which is revoluble' on a pivot pin 21 supported by the cam yoke. This cam is adapted to cooperate with the periphery of a continuously revolving roller 22 when the respective key bar 15 is elevated by manipulation of the respective key lever, such movement of the key bar causing the bell crank lever 16 to operate in a manner to lower the cam yoke and thus permit the cam to come in contact with the roller, a projection 28 on the cam normally resting against a toothed bar 2 1 to hold the cam in an inoperative position although disengaging from the bar 2% when the cam yoke is lowered.

A- row of escapement actuating reeds 25 is provided to correspond with the row of escapements, these reeds restlng on the vertically movable ends of the respective cam levers 18 and they are guided at their lower ends by the bracket 26. The upper portions of the reeds 25 are guided by a bar 2 which prevents lateral displacement of the reeds, thus maintaining them in cooperatlve relation with the respective escapements, but each reed operates in a slot 28 in the bar 27 whereby the reeds may become deflected in the planes of their respective escapements. The upper end of each reed is formed with a beveled surface 29 which is adapted to cooperate with the beveled surface 13 of the corresponding escapementactuating lug 12, and each reed is acted upon by a tension spring 30 which operates preferably to draw the reed in a diagonal direction downwardly to maintain it in proper relation to its respective cam yoke and to maintain its upper end in operative relation to the respective escapement actuating projection. hen one of the reeds is elevated by its respective cam yoke, the spring 30 will act tohold the upper beveled end of the reed in contact with the corresponding actuating projection 12 on the respective escapement until the escapement has been actuated and caused to assume the position shown in Fig. 2 whereby the foremost matrix in the respective magazine channel is released by the dog 4 of the escapement and the following matrix is arrested by the dog 5 of the escapement, and when the escapement is so operated, the actuating lug 12 thereon will abut against a stop 31 which is formed at the under side of the magazine. In operating the escapement in this manner, the force of the spring 30 is suflicient to overcome the strength of the escapement-returning spring 8. However, when the escapement actuating projection 12 abut-s against the rigid stop 31, further movement of the escapement is pre vented and the excess motion or overthrow of the reed is compensated for by a deflecting action of the upper end of the reed, which causes the latter to assume an inoperative position relatively to the respective escapement, the beveled surface on the upper end of the reed riding toward the outer end of the projection 12 of the escapement as shown by the full lines in Fig. 2, the spring 30 yielding to permit such movement of the reed, and when the cam yoke returns to initial position the reed will be restored to initial position by the action of the spring 30, the escapement being restored by the operation of its spring 8.

I claim 1. In a linotype machine, the combination of a magazine having a matrix controlling escapement, actuating mechanism thereof, and a reed operative by said actuating mechanism to engage and positively actuate the escapement to release a matrix and yieldable into an inoperative position relatively to the escapement to allow overmotion of the reed.

2. In a linotype machine, the combination of a magazine having a matrix controlling escapement, actuating mechanism therefor, a member operative by said mechanism and cooperative with the escapement, and means for holding said member in operative relation to the escapement until the latter has delivered a matrix and yieldable to permit said member to deflect laterally and assume an inoperative relation to the escapement and thereby allow overmotion of said memher.

3. In a linotype machine, the combination of a magazine having a matrixcontrolling escapement, actuating mechanism thereof, and a longitudinally movable reed operative by said mechanism and having a beveled surface to engage and operate the escapement to deliver a matrix and yieldable into a deflected relation to the escapement to allow overmotion of the reed after the latter has operated the escapement.

4. In a linotype machine, the combination of amagazine having a matrix controlling escapement, actuating mechanism thereof, a reed reciprocable by said mechanism, the reed and escapement having cooperative surfaces beveled diagonally of the direction of movement of the reed, and means for retaining such surface in operative relation to actuate the escapement, and permitting a slipping action between such surfaces as the reed continues to operate after the escapement has delivered a matrix.

5. In a linotype machine, the combination of a magazine having a matrix controlling escapement, actuating mechanism therefor, a reed reciprocable by said mechanism, the reed and escapement having cooperative surfaces'beveled diagonally of the direction of movement of the reed, and means for retaining such surface in operative relation to actuate the escapement, and causing deflection of the reed after the latter has caused delivery of a matrix bysaid escapement.
