ELEVATOR-OPERATING MECHANSM FOR LINOTYPE-MACHINES.

Specification of Letters Patent.

Patented Feb. 24, 1920.

Application filed November 14, 1919. Serial No. 338,048.

To all lwhom 'it may concern:

Be it known that I, GUs'rAvUs S. LoRrNG, a citizen of the United States, residing at "Watertown, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Elevator-0peratino Mechanism for Linotype-Machines, of which the following is a specification.

This invention relates to means for raising and lowering the elevator which constitutes an element of a linotype machine, and receives a line of matrices from the usual lreyboard-controlled mechanism, and raises the line to position for transference to the usual line-delivery-carriage.

The object of the invention is to provide improved means whereby the operator, by depressingl a manually movable member or key lever, is enabled to connect the elevator with a power-driven member of the machine in such manner that the power will raise the elevator.

The invention is embodied in the improvements which 1 will now proceed to describe and claim.

Gf the accompanying drawings forming a part of this specification- Figure 1 is a front elevation of that portion of a linotype machine which includes the elevator and mechanism embodying the invention for raising the same, the elevator being` in its lowest position.

Fig. 1n is a view similar to a portion of Fig. 1, showing certain parts in different positions.

Fig. 2 is a section on line 2-2 of Fig. 1, and a plan view of parts below said line.

Fig. 3 is a fragmentary sectional view on line 3-3 of Fig. 4.

Fig. 4f is a section on line 1f-4 of Fig. 1, and an elevation of parts at the right of said line.

F ig. 5 is a. fragmentary view, showing, in

side elevation, the carrier hereinafter de-y scribed, in its inoperative position.

F ig. 6 isa View similar to a portion of F ig. 5, showing the carrier in its operative position, and the push bar part-ly raised.

Fig. 7 is a view similar to aI portion of Fig. 6, showing the push bar additionally raised.

Fig. S is a fragmentary view similar to a portion of Fig. 5, showing a modioation.

The same reference characters indicate the same parts in all of the figures.

The elevator the general construction of which is well known, is designated as a whole by the reference numeral 12, the elevator being movable, as usual, in fixed vertical guides, 13 and 14, and adapted, as usual, to receive a line of matrices from the inclined guide or chute 15, and to elevate the line to position for transference by the usual assembler slide, t0 the usual line delivery carriage, Said carriage being reciprocated by the usual oscillatory carriage arm 1S attached at one end to a rock-shaft 19, which is rocked lby the power of the machine.

21 represents one of the usual powerdriven shafts of the machine, this being, for example, the shaft of the usual rubber roll forming a part of the automatic mechanism controlled by the keyboard for delivering matrices to the elevator. The parts above described involve nothing new, with me, excepting that the shaft 21 is utilized to rotate a driving gear 22, constituting an element of my improved mechanism, and attached to one end of said shaft.

The gear 22 constitutes the driving member of a clutch, the driven member of which is a shiftable gear V23, adapted to mesh with the gear 22, as shown by Fig. 6.

I have provided driven-member-shifting means for engaging the driven member with the driving member, at the will of the operator, the driven member being rotated by the driving member, and connections between the driven member and the elevator organized to raise the elevator when said members are interengaged, the said shifting means being embodied in the elements next described.

The carrier 9A@ is normally held by its own weight and that of the elevator, in the inclined inoperative position shown by Fig. 5, the center of gravity of the carrier being at the left of the center of oscillation Q5. hlounted to oscillate on a stud 26 ixed to the carrier 24, is a sleeve 27 having an outer arm 2S carrying a trundle roll 29, and an inner arm 30, to the outer end of which is secured one end of a spring 31. The sleeve 27 and arms 28 and 30 constitute, in effect, a bell-crank lever. The opposite end of said spring is fixed to the carrier 24. Said arms project at different angles from the sleeve 27, as shown by Figs. 1 and 1, and the trundle roll 29 on the arm 28 is in the path in which the carriage arm 18 oscillates. The

arrangement is such that when the carriage arm 18 isat the extreme of its movement shown by Fig. 1, it bears on the roll 29 and holds the arms 28 and 29 in the positions shown by Fig. 1, the arm 30 being raised Aand putting the spring 31 lunder such tension that it tends to swing the carrierv 24 to the operative position shown by Figs. 6 and 7, and thus engage theV driven gear 23 with the driving gear 22. In other words, the spring isset for action by the carriage lever'. Action of the spring to cause this swinging movement is not permitted, however, until the operator depresses a trip lever 32 by means `of-a key 33 on the outer end ofsaid lever.y The inner end of said trip lever 32 is mounted to swing on a stud 34 fixed to the frame of the machine, and passing through al slot 36 in the carrier 24. A shoulder 35 on the trip leveris normally held by a spring A3,7, in engagement with a lug 38 on the caronthe carrier 24, and is movable endwise by the driven gear through suitable connections therewith, one end of said bar bearing on an abutment on the elevator. The push bar as hereshown, is provided with rack teeth 4 meshing with a gear 42, the shaft 27. The shaft 27, the gear 42, and the rack teeth constitute connections between the driven member 23 and the push bar which'operate when the driving and driven members are interengaged, to raise the push bar and cause it to raise the elevator. The abutment on the elevator with whichV the pushV bar cooperates, is preferably constructed to form a cushioning buli'er which arrests the elevator without jar at the upper end of its movement. Said abutment is preferably embodied in a rod (F ig. 3), movable in a socket 46 in an arm 4T on the elevator, and provided at its upper end with a stop nut 48, and at its opposite end with a head 49, having ears in which an antifriction roll v50 is journaled, and a spring 51 (Fig. 3), interposedV between the head and a shoulder at one end of the socket 46.V The roll 50 contacts with the upper end of the push bar when the latter is raised, andis in rolling ,contactv with the push bar to compensate for the swinging movements of the carrier and push bar. i

The driving and driven gears remain in engagement so long as the carriage lever 18 remains 1n theposition shown by Fig. 1.k

whichis iix'ed to as shown by Fig. 1a, the spring 31 contracts until its tension is no longer sutlicient to Vhold the gears interengaged, whereupon the carrier 24 swings back to the inoperative position shown by Fig. 5, and separates the gear 23 from the driving gear, so that the push bar and elevator are free to drop. This movement of the carrier permits the key lever shoulder 35 to again engage the lug 38, and thus lock the carrier-in its inoperative position,and enable the spring 31 to be again 'set for action by the carriage lever 18. The spring 31 in contracting depresses the arm 30 and raises the arm 28 to position to be again acted on by the carriage lever.

- lt will beseen that the-machine, as above described, includes carrier-#shifting mechanism embodied in the manually movable lever 32, and means coperating therewith to shirt the carrier to its operative Vposition when said lever is manually moved, said coperating means including the carriage arm 18V the shitting spring 31, and the bell-crank lever in the path of the carriage arm and connected with the shifting spring, the lever 3G being adapted to lock the carrier in its inoperative position while the spring is being set for action, and to release the carrier and permit the spring to act.

Fig. 8 shows a differently organized carrier-shifting mechanism, embodied in a manually movable lever 32a, pivoted at 34FL to a iixed support 2ba to which the carrier 24 is pivoted at 25a. The lever 32a is provided with a short arm projecting from the opposite side of the pivot A3d-Zand bearing on a pm or abutment 56 fixed to the carrier 24. A spr1ng57 secured at one end to the Vcarrier Y `and at the otherend to the machine trame,

normally holds thecarrier in its inoperative position, the' arrangement being such that-the carrier is shifted to its operative position, and held in said position by the muscular force oil the operator exerted on the lever'32, until the elevator reaches its highest point. i 'i Y While the coperating means shown by Figs. 1 to 7, is preferred by me because the operator is required only to exert on the lever 32 the force required to unlock the carrier, and is not obliged to hold .the lever while the elevator Vis rising, I elect to claim vbroadly in this application carrier-shifting mea-ns including Va manually movable lever and means coperat'ingtherewith, to shift the carrier to its operative position when the lever is manually'moved, whether the said coperating means be embodied as shown bv Figs. 1 to 7 or votherwise embodied, as shown for example by Fig. 8.

The elevator is arrested 'in its raised position'by the meansusu'ally employed for that purpose in linotype machines. In the verv brief period between the arrest of the elevator and the movement of the carriage arm 18., which causes the separation of the driven gear n3 from the driving gear Q2, in the preferred embodiment of the invention, the rotation of the driving gear shaft 21 stops momentarily, owing to the fact that said shaft is driven by a belt, not shown, running on a pulley on the shaft and adapted to slip o'n the pulley. The said belt also slips on the pulley when the invention is embodied as indicated by Fig. 8, and when the operator holds, the lever 32a depressed after the arrest of the elevator in its raised position.
