rocal, and is transmitted through a leverage system by means of a pawl which causes to be rotated a ratchet wheel and shaft associated therewith. A cam carried by said shaft is provided with a plurality of apices or high points and nadirs or low points which present themselves alternately and during successive cycles.

A lever responds to this reciprocal motion throughsuitable linkageand is connected with a carriage that supports a plurality of horizontally shiftable release reeds that are capable, during each presentment, of being associated with a corresponding one of a plurality of adjacent fmatrix channels. In this manner the successive elevator operations being representative Ioi -correspending performances of linecompos'ition, are caused to shift the release mechanism of certain characters to be associated with various -ones of `a plurality of channels.

For a better understanding of the present invention, reference should be had-to the accompanying drawing and to the following description wherein like reference characters designate similar parts throughout.

A tape sensing mechanism, generally referred to as a record reader, is indicated by the reference characterY M. 'This device lresponds to transverse rows of perforations in'a tape I2 and accordingly causes to be positioned ya set of code bars 13. For each condition of the `several vcode bars, a function performing element is placed into selective condition. Among several such elements one indicated i4 is delegated to the function -of initiating the performance of the matrix assembly elevator operating mechanism. Upon being selected, it is moved forward (towards the observer as illustrated in the accompanying iigure), and in so doing, rotatesa three-armed lever l5 in a counterclockwise direction. To lone of the arms of lever l5 is connected a latch bar I-6 and `to the latter is pivotally articulated at .lil oneend of aoating lever 18. The opposite' end I9 of lever I8 is-supported-between a pair of forked elements integrally formed with .a :connecting rod 211, the opposite end :of which is,piv otedat `22 to aidepending arm rof afcradle member v23 which rocks about a horizontally supported shaft 24.

Another arm 25 of cradle `member23 :extends downwardly and leftwardly, as 4viewed in this figure, and 'is -shaped arcuately and .provides inwardly thereof a Vshort radius section 26 .and :a somewhat longer radius section 21. IIn cooperation with these sections there is supportedV a camming lever 28, the depending portion V29 Yof which ris provided with 'a beveled sectionV which engages the .surfaces 25 Yand 21 in accordance with the position of lever '2.8. A spring 3D `tends to maintain the follower roller 31| :of lever .28 in constant Iengagement with a delivery slide arm 32. Following the raising of the assembling.

elevator when the' latter attains the fline delivery .slide level, slide Yarm :32, rocking counterclockwise in a well-known manner, together .with the movement of the line delivery slide, rotates about its pivot 33, withdrawing its surface from engagement with roller 3l and permitting a spring 34, connected to a cooperating bail 35, to urge lever 28 also in a counterclockwise direction about its pivot 31.

In so doing, the beveled surface 29 is withdrawn yfrom engagement with :short radius surface 2.6 and presented oppositelong radius surface 21. This permits cradle member 23 to be rotated clockwise as is its `tendency to do under the influence of a spring 3S which urges connecting rod 2| leftwardly.

The utility of floating lever i8 and its cooperation through connecting rod 2l and cradle 23 as an intercontrol device between the record reader mechanism Il and the delivery slide arm 32 is well known and forms the subject matter of a copending application Serial No. 600,606, filed March 23, 1932 mentioned above. Because of its Ifrequency of operation, it is particularly adapted to initiate the performance oi the mechanism constituting the present invention and zabout to be described. For purposes of understanding the present invention, suiiice it to say that the aforedescribed reciprocal movement of lever 28 Icoincides with each elevator operation which 'in turn corresponds with the assembling and delivery of each group of matrices that is composed for the purpose of casting a line slug.

Integrally formed with cooperating bail 35 is an,.upstanding arm 38 to which ,is connected a pawl 39, spring urged to engage the teeth of Va ratchet wheel 4l, while a latch pawl 40 pivoted to a. stationary part of the machine also engages the teeth of wheel 4l. In accordance with the particular illustration, ratchet wheel 4l is provided with eight ratchet teeth in longitudinal alignment with eight corresponding positions on a quadrilateral cam 42. In other words, alternate teeth of wheel 4l coincide with associated apices-43 and nadirs 44 oi cam 42.

A lever 45, pivoted at 46 is provided with a depending arm 41 having a projecting portion that is urged by a spring 48 to engage the periphery of cam 42. The opposite or upstanding arm of lever 45 is connected as at 49 to a spring 5|, which in turn is secured to a lug 52 integrally formed with a horizontally slidable bar 53. As the cam 42 is rotated, it presents alternately an apex '43 and a nadir 44 to the projection of depending portion 41 of lever 45.

This causes lever 45 to reciprocate coincident with each actuation by pawl v39 of wheel 4| and cam 42 and accordingly to impart a similar `movement to bar 53, spring 5| acting as a resilient element to Yprevent `possible rupture lthat might otherwise result if the movement of bar 53 were impaired and it could not respond to the urge of lever 45.

Throughout its length, bar 53 is provided with notches l54 within which reside individual release reeds '55 -free to verticalmovement that may be imparted thereto through the escapement mechanisms 56 that are tripped by the weight bars 51 under the actuation 4of levers 58which may be controlled either manually by` means of key tops 59 -or automatically through the agency of the bell crank levers 6|, as described in the copending application referred to above.

When bar 53 is moved horizontally, it `:accordingly shifts reeds into either of .alternative positions as .indicated in solid and broken lines, during which vthe reeds .55 are eachk permitted Ato register Withone or the other of a pair of cooperating reeds y62 `and 63 with which eachshiftable reed 55 is associated. Cooperating reeds 62 and -63 :control escapement elements `64 of ad.

joining matrix channels 55. During the association of Ya Imain operating. reed 55 with its cooperating reed V(i2, the selective operation thereofY -causes to be released matrices from one of the adjacent channels 65, while during the association lthereof with the vother vcooperating reed 63` there may be effected the release .of matrices fromfthe adjoininnggchannel 65. Since the shirting lever operates to shift reeds 55 coincident with consecutive elevator operations, matrices from adjoining channel are alternately released in accordance with successive lines of composition. This permits of a larger source of supply to be availed of under the control of a single release reed 55.

When the matrices are released from their respective channels, they are permitted to precipitate through individual chute chambers that are arranged in a collective chute 66, whence they are vcarried in a well-known manner to the assembling block in the course of line composition.

It should be understood that the association of the shift operating mechanism forming one adaptation of the present invention may be associated with other actuating devices than the one illustrated in the instant case, namely, the elevator operating mechanism. Likewise, it should be understood that numerous changes and modifications may be made without departing from the spirit or scope of the present invention. For this reason it is not intended to be limited to the details illustrated in the accompanying drawing nor to the language employed in the foregoing specification, but to be permitted instead a latitude of interpretation as indicated by the hereinafter appended claims.
