Fig; is a vertical Be it known that 1, John' 11. Romans, of Brooklvn, New York city, county of Kings, and St at e of New York, have invented a new and useful Improvement in Linotype-Ma chines, of which the following is a. spec-itiea tion. v

My invention hasreferenee to an improved escapement device for" releasing shouldered matrices one at.- a time from a channeled magazine. a

It. relates to that class of escapenients wherein a eelt-trally pivoted lever is-provided' at. opposite ends with shoulders or pawls', which are projected alternately into "the magazine and intothe path of'theuntitriees'f so that when the foremost ma'trixis released. i

the next one is permitted to assume its place, 1 as represented, for example; in Letters Patent of the United States Nos. 392,446 and; 436,532.-

The aims of the. invention are to lengthen the life of theeset'tpement to reln'deri 9.0:". tion eertu-in regardless of the speed a't'w deliit ismoved, to ehea on and simplify .the cori-' strue-tiou, and to essen theft i'egtf on the matrices. Y

To this eud'it consist-'5 in a' centrally oted cscapement-lever carrying at opposite ends shoulders or pawls which.ztre'sepurated a distance greater than the length of a matrix.

llcretofore in all escape-merits of this class the operative lengththat isto say,v the distance between the. outer sides of the two ac tive shoulders or pawls-'-has been less than the distance between the ears at the opposite ends of the nuttrices. In "constructing in escapement. 1 give .the same a greatl v-in creased length in proportion to the-length of the matrices,'the distance between the two pawls or shoulders heing greater than the en- 1 tire length of a. matrix, this change resultin"; in a marked change 'in their mode of action on the matrices. v In the. drawingsv Figures 1, 2, 3, and-1 are vertical sections through a. magazine eontaiuing matrices and provided with my im proved cscapem'ent. Fig. 1 illustrates the. normal positions of the parts, and the follow ing figures the successive positions which the parts assume in releasing one matrix and permitting the next to, take its place. I Fig.5 is a; perspective view showing the slot in the under side of the magazine to admit the escross-section through the lower end of I the magazine, sliowing'the rel atioiiof' the escapel meu'ts to tlie m'agazine plates and the grooves t therein. lfig; 7' is; a 'vertical cross-section i through'dtie ofthe magazines'on matinee 6, Figs. 1. mid? 5;illustrating:the Iilitlil1r in which ese a p'ei'nents of uniform \\-'idtlt'n1t'ry be used with c ani ielsof different widths.

Referring to the. drai'tin'gs, A- 'represents an inclined"nitigii2i1 eebtisisting= or parallel: top

and fb'otto'm platesyy having their innerfaces the magazine, is preferred; ="E1tchf'eseapejco'ntrol of finger-keys, various unechanisms 5 of a matrix, the distance between the shoulders d and (1 being preferably about one and one-half times the over-all length of a matrix. Owing to this fact and to the fact that the upper shoulder d of the escapementis held normally in the elevated position, (shown in Fig. 1,) the foremost matrix is retained at rest within the magazine by said upper escapement-shoulder, bearing beneath or in front the upper orrear earb of the matrix. When the position of the escapeme'nt is reversed, the upper shoulder 11 is withdrawn and the matrix permitted to pass thereover,. as shown in Fig. 2, the lower shoulder d of '-the escapement' being at the same time raised, so that the advancing martix finall contacts at its forward end with said 'shou d'er d, whereby it is temporarily arrested in the manner shown in Fig. 3. During this action the foremost matrix advancesabout onehalf its length. It is followed by the second matrix, which rests against-the first with its upper ear b some distance behind the rear shoulder d of the escapement. The escapement is speedily released and permit-- ted to assume its first'position, as shown in Fig. 4, the effect being to withdraw the forward shoulder d ,-so that the foremost matrix may escape'thereover, while at the same time the advancing second matrix is arrested by the rear escapement-shoulder d", which is raised within the magazine in advance of the matrix-ear b.

It is to be observed that-when the parts are in their normal positions the foremost matrix is held at rest by the engagement of its up er, or rear end with the upper or rear shouldhr of the escapementand that when the position of the escapement is reversed to release the foremost matrix the latter is arrested momentarily contact with the' lower or forward end of the escapement, which acts against the outer end of the matrix. When the scapement resumes its original position, its upper end engages the upper ear of the second matrix.

It will be seen that eachmatrix is released by two successive.movements and that the upper ear of each matrix engages but once with the escapement.- In escapements of this class, as heretofore constructed the rear matrix-ear I) encountered the two shoulders of the escapement successively, so that this ear was subjected twice to the wear and impact due to the momentum of the advancing column of matrices. The present construe-- tion therefore reduces by one-half the wear and the blows ,against the ear of the matrix.

As this ear is reliedupon to secure the proper alinement of the composed matrices in front of the mold, thereduction in wear is of great importance.

As the released matricesdescend by grav ity and at varyingrates of speed under different conditions and as there is occasional variation in the speed of the escapement, it is'of great importance that the greatest possible latitude should be allowed inthe movement of the escapement, so that theforemost matrix may have ample time to escape andthe second matrix have ample time to assume the position vacated by the first without danger of the escapement-shoulders striking the outer edges of the matrix-ears or of their failing to'properly engage the same. B giving the escapement the increased lengt -1n the manner shown and described, so that the time required for the passage of a matrix from its upper to its lower end is increased, 1 am enab ed to operate the machine at high speed and to release the matrices in quick succes-' sion without danger of the failure of the parts to operatein the proper manner. Another' advantage resulting from the increased lengltsh o the escapements'is the fact that the pat of the shoulders have less curvature than they.would have if a short'escapement were used. It is desirable that the shoulders should move as nearl as possible at right anglesto the path in w ich the matrices move,

this in order to reduce the wear of the matrix- 'sidered impractical to use,escapements made separately constructed and pivoted or jointed-to the lever, as in-Patent o.-436,532, the increased length of the escapement being attended with. certainadvantages in such case. In view, however, of the satisfactory manner in whichthe lengthened escapement in one piece operates, and in view of the fact that it may be made at very much less cost than the esca ment with pivoted shoulders or awls I pre' er the one-piece construction;-

n order to permit the entrance of the u'p-y per shoulders (1 into the magazine, the latter I may be provided with suitable'holes; but I prefer, as shown in Fig. 5, to provide the magazine in the under side with a continuous slot. a, extending transversely thereof to admit the shoulders (1 The trans verse slot a is of a width just su'illcient to permit the entrance of the upper escape men t-shoulders (l and of. such width that it is impossible for the earsof the matrices to fall therein as they passthereover; We're the slot of greater width, there would be danger of the matrices be in arrested or retarded intheir course to the de ivery-poin't, As the -rio ments which are of uniform width or thickness,'notwithstanding the variation in the width of the magazine-channels or grooves,

and also possible to use the continuous slot a without losing control of the matrices.

[O The lower shoulders cl may enter through a corresponding slot, or: they may be'seated beyond the end of the magazine-plate.

The provision of a transverse continuous slot admits the use of escapement-levers of r5 uniform width'or thickness throughout the magazine. The channels a in the magazine are of varying widths, and heretofore it has been the practice to make the escapement pawls or shoulders of corresponding widt'hs,'

or, in other words, of a number of different widths in each magazine. The employment i of escapements of uniform widths or thick nesses 1s a great advantage in that it simplifies the construction and greatly reduces the 2 5 cost of making and fitting the parts.

Having described my invention, what I' claim is 1 Inal1notype mach1ne, the combination of -a magazine, shouldered matrices, and eso capementdevers having a length between its shoulders greater than the length of the matrices.

2. In a linotype-machine, the channeled magazine, in combination withshouldered matrices, and-escapement-levers each arranged to enga c alternately the rear ear and e the forward em of-the outgoing matrix.

3. In a linotype-machine, the combination of a magazine and matrices, with escape- 4o ments, each having its front and rear ends matrices and a continuous transverse slot in arrangedto engage respectively with the front and fear ends 'of the outgoing matrices. 4. In a linotype machine, the magazine having longitudinal channels to guide'j the the under side to admit the escapements, in

combination with the escapement-support seated whollyon the outside of themagazine, and the pivoted escapements having their upper ends or shoulders projected into and adapted to fill the slot in the magazine.

5. In a linotype-machine, the longitudinally-channeled magazine having a transverse slot therein, in combination with a series of pivoted onepiece escapements, each having the lower end adapted to engage the matrices at the extremity of the magazine, and the upper end adapted to enter and fit the transverse slot.

-6. In a linotype-machine, an oscillating escapement arranged to engageat its front and rear ends successively with the front and rear end of each passing matrix.

7. In a linotype-machine, the combination of series of matrices and an escapement adapted to engage at its lower end with the forward end of one matrix, and at the same time extend at its opposite end beyond said matrix position to engage a following matrix.

8. In a linotype-machine, a magazine provided with longitudinal channels of varying widths, and' with a transverse slot, in combination with a series of escapement lever's of uniform width arranged to act at one end through said slot; whereby the escapements of uniform thicknesses are adapted to control matrices of different thicknesses.

9. In combination with a magazine having longitudinal channels,'and a transverse slot intersecting said channels, a series of escapement-levers ofuniform thickness, and a slip portE with longitudinal grooves to receive .the escapements; whereby the escapements are kept in proper operative relations to the longitudinal channels.

' In testimony whereof I hereunto set my hand, this 30th day of August, 1906, in the presence ofitwo attesting witnesses.
