tween each escapement and the keyboard. for talnng up all overthrow or excess motion which may be provided to compensate for Wear of the cam roller and the parts between it and the escapement, certainty in operation of the escapements being thereby insured.

To these and other ends, the invention consists lncertain improvements, and comblnations 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 .is a perspective view of a section of the mechanism of a linotype machine which controls the delivery of matrices from the magazine, the escapement mechanism shown 'tirerein embodying the present invention; Fig. 2 represents a vertical section of the structure shown in Fig. 1, the parts being in normal. or inactive condition; Fig. 3 is a view similar .to Fig. 2 showing one of the escapements actuated to release and cause de livery of a matrix from its respective channel of the magazine; Fig. 4 is a perspective view of one of the escapement members and its mounting. Fig. 5 is a view showing dia- '-j grammatically the converging, matrix channels of the magazine and the corresponding convergence or angularity of the cscapement grooves in the escapement bar.

Similar arts are designated by the same reference ciaracters in the several views.

Heretofore in machines of this character,

the escapements, which control the delivery Ofiillfi matrices from the magazine, have been pivoted on a pin operatin; in a hole in the escapement, the pin forming the axis of oscillation of the escapement points. Owing to the fact that the channels of the magazine contain a-large number of matrices which are fed by gravity to the rcsl'icctivo escapeinents, considerable wear between each cscapement and its pivot pin has resulted in previous constructions due to the repeated .checku'ig of the line of stored matrices by the escapement during the delivery of the matrices, and experience has shown that the wear so produced results 'l'rcqucntlv in faulty delivery of the matrices, occasioniug numerous delays in the operation of the ma- The present invention provides a construction which obviates the defects andobgection incident to the escapemcnt mecha- -more readily as compared with previous 1 n constructions, the escapement member. in the preferred embodiment of the invention be- 7 mg in one pleoe, thus reducing materially the number of'partsand connections employed, and the escapement is so mounted as to mmlmlzef wear and to 2118111684111 correct working relations of the parts." 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 restricted to the particular construction h shown as equivalent constructions may be usedwithin the scope of the claims.

In the present instance,the improvements are shown in connection with the well known linotype machine, the keyboard mechanism of which embodiesthe usual key levers 1 cooperating with the vertically movable key bars 2 and the atter cooperating with the bell-crank levers 8 which are pivoted at 4 on the cam frame}5,'these bellcrank levers controlling the cam yokes 6 in the usual manner, these cam yokes being pivoted at 7 and having cams 8 journaled thereon, the cams being arranged to cooperate with the continuously revolving cam rollers 9. Each cam -is normally held in inoperative position by a pin 10 thereon which oooperates with a toothed bar 11, lowering of the cam yoke serving inthe usual manner to set the cam 8 in coiiperative relation with the respective cam roller 9, and rotation of the latter serves to elevate the cam yoke and thereby operate the respective'escapement to deliver a matrix from the corres )onding channel .of the magazine. In th "present embodiment of the invention, means is interposed between the keyboard mechanism and the escapements to take up or compen sate for overthrow or excess motion of the cam yoke, such excess motion being preferably provided in order to allow for wear of the cam roller and the associated parts. In the present instance, the escapements are actuated by a set of vertically movable reeds 12 which are guided by the bars 13, each reed resting on and coi perating with an actuator which is operated by a corresponding cam yoke. In the preferred form, each actuator embodies a plunger 14 which is fitted to operate vertically in the cam frame 5 and the upper end of this plunger forms a head which cooperates with the bottom of its respective reed. The plunger is formed with a chamber 15 and an auxiliary plunger 10 is provided which is capable of 'moving-axially in the chamber of the plunger 11 and is permitted a limited movement with respect to the plunges 14 by the transverse pin 17 which operates within gaged by the respective cam yoke when the same r ses and the spring 19 then serves to transmit the .movemcntof the auxiliary plunger 16 to the plunger 14 and the latter will actuate its respective reed and the reed in turn will operate its respective escapement to release and cause delivery of a matrix from the corresponding channel of the magazine. When, however, the cam yoke as an excess motion, the plungers 14 and 16 will move in unison until the escapemerit has reached the limit-of its movement, and further movement imparted to the plunger 16 by the cam yoke causes compression .of

the spring while the plunger 14: remains at rest, the spring constituting a yielding or compensating connection between the cam yoke and the reed.

The magazine 20 is shown in'the present instance as provided with the usual channels 21 to contain the matrices, the matrices bein'g fed to the es'capements and to the mouth of the magazine by gravity. The improved escapement mechanism provided by the present invention embodies a set of escapements corresponding in number and position to the magazine channels, each escapement in the preferred form of the invention embodying a member 22 which is of segmental'form and made in one piece. Each escapement member in the present instance is substantially semi-circular in form and 1t has a concentric inner bearing edge 23, the

ends of the memberv forming pallets orstops 21 and 25 to coiiperate with the ears on the matrices and thereby control the movements thereof toward the mouth of the magazine.

finch escapement member is also provided secured by screws 30 to the underside of the magazine, and this bar is formed with a number of concentric segmental grooves which correspond in number. and arrange: ment to the es't'apemc'nt members, these sege mental grooves in the bar receiving the .different escapement members and causing the same to oscillate about a glvenaxis andpreventing lateral displacement thereof. cording to the present invent1on, the axis of oscillation of the escapement members is located preferably on a line betweenthe pallets or matrix-engaging ends thereof and is within the channel portion of the longer drical bearing for the respective escapement',

the axis of which bearing is at a rightangle to the plane of the respective escapement and the corresponding matrix. channel of the magazine, this right angular relation between the escapements and the axes of their bearings being maintained across the width of the magazine, notwithstanding the fact that the matrix. channels in the magazine are convergent, asshown in Fig. 5, and the escapements bear a corresponding convergent relation. The upper side of the bar 29 ivhich in the present instance forms a portion of the bottom of the magazine is formed with grooves or channels 32 which constitute continuations of the channels or grooves 21 in the bottom of the magazine. Each escapement is provided with 1 spring 33 which is supported by a block 3 and acts on the lug or projection 26 of the escapement to counteract the respective-reed and to restore the escapement to normal position after each actuation thereof. A guard or cover plate 35 is also provided which is secured to the under side of the magazine, it forming a housing for the springs 33 to protect the same and it has a lip or extension 36 which bears on the under sides of the escape'ment members to retain them in their res ective bearings provided by the bar :29.

he operation of the mechanism shown may be briefly described as follows :\l"hen the key bar 2 is elevated by manipulation of its respective key lever 1, the cam yoke 6 will be lowered, permitting the'corresponding cam 8 to be rotated by reason of its engagement with the continuously revolving cam roller 9., the cam yoke being thereby ele vated and the upward movement of the cam yoke will carry it, into engagement with the auxiliary plunger l iand cmitinued rising movement it the ram yoke will cause the plunger it and its correspmding reed to be elevated through the medium of the spring 19 which is operated by the plunger 16. The reed will act on the actuating projection 27 of its corresponding escapement, causing the same to move from the position shown in Fig. 2 into the position shown in Fig. 3, the projection 25 on the escapement thereby reasing the lowermost matrix in the re spective magazine channel and the projec' arrestingof the movement of the plunger 14 and its respective reed. When the keyboard mechanism has returned to normal position, the reed and its corresponding plunger 1% will descend and the escapement will be restored to its normal orinitial position by its respective spring.
