TYPOGRAII-IICAL MACHINE.

This invention relates to improvements typographical machines provided with a detachablematrix storage magazinetand the invention has reference, more particularly, to an improved matrix locking device which is mounted on the magazine as a permanent or non-separabie fixture thereof.

This invention has for its principal object to provide an improved construction of matrix locking device in the form of a rotatable locking bar which is assembled with the mouth or discharge end of the matrix storage magazine in permanent relation thereto, and which, by simple rotative movement, may be brought into matrix locking or releasing position at will, together with means to secure the bar in either such locking or releasing position; said rotatable locking bar is also provided with a novel means adapted to cooperate with a magazine locking device so as to release the iatter. for

disengagement with the magazine when the locking bar is turned to matrix locking position, and so as to prevent manipulation thereof to unlock the magazine while the locking bar is turned to and positioned in matrix releasing position.

This invention has for a further object to provide such a construction of rotary looking oar, that, when the same is rota-ted to matrix locking position, it will at the same time lift or retract the stored matrices to remove the weight of the same from the escapement devices of the typographical machine.

Other objects of this invention, not at this time more p .rticularly enumerated, will be clearly understood from the following detailed descriptionof the same.

This invention is clearly iliustrated in the accompanying drawings, in which Figure 1 is a plan view of the discharge end portion of a matrix storage magazine equipped with the novel rotary matrix looking of this invention, and showing the cooperative relation of said locking bar, while in matrix releasing position, with one style of m azine locking latch; Figure 2 is a transverse section, taken on line 2-2 in Figure l, but showing the cooperative relation of said locking bar, while in matrix locking position, with said magazine locking latch; Figure 3 is a fragmentary vertical c oss section,onan enlarged scale, taken through the discharge end of the magazine,

and showing the rotary matrix locking bar in matrix releasing position; Figure 4 is a view similar to that of Figure 3, but showmg the rotary matrix locking bar in matrix loc and lifting position Figure 5 is a detail cross section, on an enlarged scale,

taken on line (i- 5 in Figure 1; Figure 6 is an end view, on an enlarged scale, of the cam member of the rotary matrix locking bar which cooperates with the magazine locking latch; Figure 7 is fragmentary plan view, onan enlarged scale,-of a' modified means for selectively retaining the matrix locking bar in either its matrix releasing or locking position; and Figure 8 is a fragmentary plan View of another style of 'mag'azine locking l a'tch with which the rotary matrix locking bar may be cooperatively associated. I

Similar characters of referenceare employed in the above described views to indicate corresponding parts.

Referring now to said drawings, the reference character 10 indicates a matrix storage magazine, in the upper and lower walls of which are provided opposing guide grooves 11, in which the ears 12 of the matrices 13 are engaged; each pair of opposed grooves 11 supporting a column of matrices 13 for downward feeding movement through and discharge from the magazine under the control of the usual escapement devices 14;. v

The upper wall of the magazine terminates a cover plate 15 which borders the discharge end thereof; ,Said cover plate possesses on its outer side, a transverse boss or enlargement 16. The under side portion of said cover plate, in alignment with its boss or enlr. ement, is transversely bored to provide bearing seatl.'. for a rotary matrix locking bar 18. Said locking bar 18 is thus mounted for rotation on its iongitudinal axis, so that proper turning movements thereof will selectively position the same in eithermatrix releasing or locking position. That portion ofthe rotary locking bar lSwhich extends across the series of matrix de grooves 11 of the upper wall of the azine, is cut awaytoprovide a flat face forming a matrix engaging abutment 19, which is shiftable, by rotation of the locking bar, either into substantially horizontal or substantia lyvertical planet relative to the plane of the magazine. lqVhen the locking bar 18 is turned in one direction, viz, from left to right, said abutment 19 is shifted to substantially horizontal plane, so as to lie substantially'flush with the bottoms of the upper guide grooves 11, thus being removed from the path of movement of the upper matrix ea'rs through said upper guide grooves 11, so that the matrices of each column or train thereof are free for dis charge from the magazine under the control of the escapement devices 14 as shown in Figure When the locking bar 18 is turned in the opposite direction, viz, from right to left, said abutment 19 is shifted to substantially vertical plane, so that one marginal edge portion thereof is projected downwardly across the upper guide grooves 11 and intothe path of movement of the upper matrix ears through the latter, so that the rearward upper ears of the lowermost matrix of each column thereof will be engaged by said abutment 19 and discharge or outward movement thereof from the magazine will be positively arrested, as shown in Figure 4.

The position of the rotary locking bar 18 relative to the escapement devices 1%, when the magazine is operatively mounted on a linotype machine, and the degree of turning movement imparted to the locking bar, when moving the same to matrix locking position, 'is such that, not only will the abutment 19 be projected into the above described matrix looking or arresting position, but will also in moving to such position exert an upward or inward moving pressure on the lowermost matrix of each column thereof, whereby the matrices are disengaged from the escape-- ment devices 14, thus removing the weight of the columns of matrices from the latter devices, and thereby obviating any risk of injury to the escapement devices when placing the magazine into service position or removing the same therefrom. This mode of operation is clearly indicated in Figure 4. When the locking bar is turned to matrix releasing position, the abutment 19, in moving away from the upper ears of the lowermost matrices, allows each column of the latter to slide downward until said lowermost matrices are brought into opera tive relation to the pawls of said escapement devices.

From the above description and an in-,

spection of the accompanying drawings, it will be clearly ap arent that thenovel rotary matrix locking bar is mounted in connection with the magazine as a permanent or nonseparable part thereof. This is of decided advantage, as compared with the heretofore known slidably removable matrix locking bar commonly used in the matrix storage magazines of typographical machines, since it is not, as is the latter, subject to loss or accidental distortion by rethereof readily yield, thereby obviating all lateral strains or stresses tending to distort or bend the matrix bodies or their ears,

which is the common accompaniment of ion gitudinally shiftable locking bars provided with matrix lifting cam portions or the like operating with sidewiee sliding etfect'relative to the matrices. V

lieans are provided on an external end of the rotary locking bar 18 both to manipulate it for turning movement, and to retain the same in its respective active'and inactive positions. In one form, as shown in Figures 1, 2 and of the drawings, this means comprises the following arrangement and construction of parts. The rotary lockingbar 18 is provided, preferably its right hand end, with a. square shank or equivalent. portion 20 of reduced cross-section, which in turn is provided with a screw-threaded portion 21 projecting from its free end. ably engaged upon said square shank 19, so as to turn with the locking bar 18, is the hub 22 of a knob or finger-piece 23. Extending axially into the interior of said knob and its hub from the outer end thereof is a socket or bore 24. Screwed upon the outer extremity of said threaded portion 21 is a nut 25, and disposed around the shank 20 intermediate the inner end of said socket or bore 24 and said nut 25 is a compression spring 26. Secured to the adjacent end of said cover plate 15 to project toward the annular peripheral portion of the knob or finger-piece 28 is a stop-pin 27. Provided in the inward face of said annular periph eral portion of said knob or finger-piece are a pair of spaced stop sockets 28 and 29 in which the freeend of said stop-pin may be selectively engaged. Preferably a shallow channel or guide groove 30 extends between said stop sockets 28 and 29. The tension of the spring 26 holds the knob inwardly pressed with one or the other of its stop- sockets 28 and 29 operatively engaged with. said stop-pin, to thereby in'nnovably retain the rotary locking bar 18 in either its active matrix locking position or its inactive matrix releasing position, as the case may be. For example, when the knob is turned from left to; right 'to-position the locking bar in inactive position, the stop-pin 27 will be engaged in the stop-socket 28, thus immovably retainingthe locking bar against accidental displacement from said inactive lia position locking bar 18 to active matrix locking position, the knob s3 is first drawn outwardly against tie tension oi the spring to release its stopsoclret 28 from operative relation to said stop-pin 27, whereupon the knob may be turned from right to left, thus turn- 7 ring the locking bar 18 to activematrix locking position and registering the stop-socket 29 opposite the stop-pin 27, so that by releasing the knob the spring 26 will bring the former into engagement with the latter, thereby retaining the locking bar against accidental displacement from its aforesaid active matrix locking position.

Referring now to Figure 7 of the drawings, there is illustrated thereby another form of means for retaining the locking bar 18 against displacement from either its active or inactive position, as the case may be. in this latter form the outer end of the locking bar 18 is provided with a knob or finger-piece 31 rigidly atlixed thereto and provided with spaced stop soclrets similar in kind and arrangement to those of the above firstdescribed construction. Slidably mounted in-the adjacent end of said coverplate 15 is a movable stop-pin 32, normally projected therefrom by a compression spring 33 which thrusts outwardly upon its inner end, in such manner that the outer free end of said stop-pin 32 may be selec tively engaged with the proper stop-socket accordingly as it is desired to retain the locking bar in either active or inactive position. Connectedwith and extending latorally outward from said movable stop-pin through a suitable opening 3% provided in the cover plate boss 16, is a finger-piece 35, by means of which the stop-pin 32 may )e retracted and released from the knob 31 when it is desired to manipulate the same in turning the locking bar 18 to active or inactive position, as the case may be.

As heretofore mentioned, this invention also includes means, in connection with the novel rotary matrix locking bar, whereby locking devices for locking the matrix stormagazine into a-linotype, machine may "be controlled in such manner as to prevent removal of the magazine from the machine until said matrix locking bar has been turned to active position to hold the matrices against escape from the magazine while the latter is removed from the 'ma chine and during other hand ing thereof. hiag'azine locking devices of various kinds employed. One form of such m azine locking mechanism is illustrated in A igures l and 2, the "same b'ein of that type which in erves bot to hold the escapement carryframe '36 in upwardly lifted operative e ion tothe magazine, and incident'ly to e lock the magazine against removal, this type or" lockingin'e'chanism bein of a islal ihen it is desired to turn the ent th with one of said swinging arms 37 is a Slll'ir I ably siuoporte'd slidable bolt 39, haviiw a nosing 40 operatively engageable with a cess 4:1 in the side of said swinging arm, to that, when thus engaged, said swinging is retained against outward movement'permitti'n'gi the disengagement of its latch 33 from locked relation to' the magazine. Operatively relatec'l' to said b01539 is a transversely 'slidable plate 42 having an oblique cam portion 4-3 which coacts with a corresponding oblique slot in the body or? the bolt, whereby transverse movements of saidplate eilwill produce movements of saidbolt toward or away from the swingi arm 3'7 to engage or disengage the nosin the former from the recess of the latter, as Said slid-able plate is p the case may be. provided at its inner side with a chamfercd nose itagainst the rearward side of which f tially alined to the axis of the rotary lock 'ing bar 18 of magazine operativeiy mounted in the typographical machine. Fixed on the left hand end of the rotary locking bar 18 15 a cam 46 having a helical face 47 (see Figure lVhensaid matrix locking be hr 18 is turned to inactive matrix releasing position,the helical cam face t? overhangs the chamfered nose 44, as shown in Figure 1, thus permitting the spring actuated movement of the slidable plate 1-2 to dispose the bolt 39 in interlocked relation with the swinging arm 37, when the latter is in operative inwardly swung position to en'- ga ge its latch 38 with the magazine. It will thus be evident that before the swine"- n, Q mg arm Br and its latch can he released from magazine locking" position, the bolt 39 must first be retracted by an outwar movement of said slidahle plate 42. T result is accomplished by turnin the the cam 46 to move its helical face 4-7 against the ch'amfered nose 44itherebv pressing outward the siidable plate L2, thro 1' such movement of the latter ret the bolt V will thus be appara-t eneethe maerixloeking bar T8 is turned to active matrix locking position, the swinging arm 37 will be released from the restraint of the bolt 39, so that it may be swung outward to remove its latch 38 from locked relation to the magazine, and consequently upon release of the opposite latch also, the magazine may be removed from the machine, it being thus assured that the matrices contained therein are safely secured against accidental outpouring or discharge therefrom, when the same is removed from and handled outside ofthe typographical machine.

In some older types of typographical machines, the magazines must first be lifted away from the escapement devices before it can be removed from the machine, and to this end the magazine is supported on a pivoted frame, which is upwardly swung by rotary cams 48 actuated by levers 49, generally indicated in Figure 8 of the drawings, and in a manner familiar to those skilled in the art. In this type of machine the cams 48 are locked against actuation, to thus prevent the raising of the magazine to a position freed from the escapement, and therefore subject to rem-oval, by means of a spring pressed pivoted latch 50, mounted on,

one end of a fixed escapement carrying bar 51, which latch 50 engages a stopprojection on the side of the adjacent cam 18. The tail portion of said pivoted latch 50 is provided with a chamfered nose 53 which is substantially alined to the axis of the r0- tary matrix locking bar 18, so that, when the magazine is engaged in operative position in the machine, and said rotary matrix locking bar is turned to inactive matrix releasing position, the helical cam face 47 of the cam 46 of the latter overhangs said chamfered nose 53. It will thus be evident that before the magazine can be raised to removing position, the latch 50 must be swung out of obstructing relation to the stop-projection 52. This result is accomplished by turning the matrix locking bar 18 to active matrix locking position, which movement rotates the helical face 47 of the cam 46 against the chamfered nose of the latch 50 to thereby turn the latter on its pivot or fulcrum to released relation to said stop-projection 52. It will thus be apparent that the cams 48 will be released for actuation whereby the magazine may be raised to removable position, it being at the same time assured that the matrices contained therein are safely secured against accidental outpourin or discharge therefrom, when the same is removed from and handled outside of the mchine.

It will be obvious that various changes may be made in the general arrangements and combinations of parts making up the instant invention within the scope of the appended claims. Hence, I do not limit myself to the exact arrangements and combina- 1,ess,oae

tions of the various devices and parts as above described in the fore oing specification, nor to the exact details thereof as illus trated in the accompanying drawings, ex cept as may be required by the limitations specified in the appended claims.
