LINOTYPE-MACHINE. I

Specification of Letters Patent.

Patented. Oct. 2, 1906.

Application filed December 8,1900. Serial No. 39,171.

To all whom it may concern:

Be it known that 1, CHARLES T. LIBBY, a citizen of the United States, res ding at Portland, in the county of Cumbcrl'nnd ,and State of Maine, have lnvented certain new and useful Improvements in Linotype-Machines; and I do hereby declare the following to be a full, clear, and exact dcscripton of the invention, such as will enable others skilled in the art to which it a'ppertains to' make and use the same.

My invention relates to improvements in the Mergenthalcr linotype-machine of the general character represented in Letters Patent of the United States No. 436,532, dated September 16, 1890.

It relates to means for raising the assembling-e'levator by automatic-actuated mechanism to be started by the operator each time it acts.

It also relates to means for reciprocating the assembling-elevator by mechanism that acts repeatedly without anything done by the operator.

It also relates to means for controlling said automatic-actuated mechanism and for bringing it into action at the will oi the oper ator.

It also relates to certain details of con' struction hereinafter described and specifically claimed.

ferred to the line-delivery carriage is released by the upward movement of the as sembling elevator. The assembling-elevator is raised by the operator by hand each time he has assembled a matrix-line, and the machine stops automatically after casting the line thus sent up and waits until the operator sends up another line. By my improvement the assembling-elevator is put up by auto- 'matic mechanism, and this automatic mechanism is either set in operation by the operw ator each time he has assembled a matrixline or, at his option, each return movement of the shaft by which the line-delivery carriage is actuated is made through interme diate mechanism to start said automatic mechanism. This latter method is valuable to the large number of operators, who are able toset news measure to the full speed of the machine and who are thus saved all labor so. In fact, having nothing left to do but be sure their line is set before the line goes up and then enjoying an instants relaxation and opportimity to glance at copy while the assembling-elevator automatlcally goes up and returns, all operators who are unable to set-lines to the full speed of the machine will have their speed increased, because my improved machine will save all interruption of their attention to copy caused by using the hand-lever to put up the assembling-clevator and the time while the elevator is passing up and back will enable them to be all ready to set the next line immediately the elevator is returned.

In the drawings herewith accompanying and making a part of this application I have only shown so much oi a Mcrgenthaler 1inotypcanachine as is necessary to illustrate the.

manner of attaching my improvements thereto and oi operating the same in connection therewith.

In said drawings, Figure 1 is a erspectivo view of lviergenthalcr machine, s iowlng my improvements attached thereto. Figs. 2 and 3 are end and side views, respectively, of the lever for operating the belt which raises the sliding collar on the operating-rod. Fig. 4 is a side elevation, partly in section, oi the supportingbrackct, assem bling-elcvator, and

Figs. 8 and 9 are views of the reversc side and end, respectively, of the back pawl. Fig. 10 is a vertical transverse sectional view, partly in elevation, showing the mechanism for releasing the latch which retains the elevator returning spring; and Fig. 11 is a detail elevation showing means for releasing the line-delivery carriage.

The same reference characters refer to parts.

As this elzisp om thro on oi oi? instantly the operator has the tent option to have the machine n5 top machine ornot. (l tells of construction show. i To I spring 3, Ti employ a releasing-screw (l in the releesingdevei 4&3, operated- 11 time by suitable mechanism as by sin 1'21. 1 20 The releesinif-levei is pivoted one steel 47, placed on column The top e l 48'is pivotally joined to body of the lever, so that y it yields upward, but not downward, and at the end cezries an smtifriotion Toll 49. jTh'e" x 25 52. The roll should be in position to be struck by arm 2i just when the line-delivery carriage has taken the matrix-line clear oi the assembling-elevator, and the lever is thus displaced the proper distance to strike latch 11 and disengage it. To set up and latch spring 8, there is attached to the sliding colllI belt 14, which. extends upwardly and passes over a pulley 15, mounted in arm l of the bracket. The other end of the belt is connected with some part of the mnchlnc which reciprocates periodically, as first elevetordever G, either diroctly'or, it this coin not be conveniently done, indirectly through sin-intermediate adj'ustirig-lever, as shown in Fi 1, which at each reciprocation draws the sliding collar up until the lockingdever engages the bracket, and. while so engaged spring 8 is inoperative. This belt uniy for convenience pass up in ide of the spring, iraveling in groove 30 in rod el. As shown in Figs. 2 end 3, the intermediate adjusting lever has two pivotullyenounted arms ill and 32, set in bracket 33. Arm 31 is coniu-ctcd with some part of the machincfrenu, by spring 34-, which tends to raise the end ol" the lever which has a slot -l01 for the reccption of a movable eye 102, lixa'nle at any point of the slot by nut 103 on the screw end of movable eye 102, tlmsfatlording means to increase or decrease the radial distance from the center of pivot-point, and thus increasing or decreasing the length of pull on belt attached to movable eye 102. The two arms of the lever are held epart by a spring 35,

I and the two arms of the lever being each pivotally mounted are capable of a certain amount of movement independent of each other, limited, however, by interlocking shoulders 36 and 37, as seen in Figs. and 3. The two arms are pivotally mounted on the bracket, arm 81 being free to fold up onerm 32 to permit the return of the passing body. The spread of the two arms is limited by the interlocking shoulders, which hold them in osition while arm 32is bein 11))Bll8tl by projects into groove 30 in the operating-rod o meriste reversilug-lever 612 to over-etc the the passing body and: arm 31 is being pulled by the belt. In the end of arm 32 is on anti frictionaoll 38, which extends out into the path of first elevator-lever G and by which it is operated.

The bearin 26 in arm 2 is fitted with a key 59, which woi ks freely in u keyway (30, cut in the operating-rod in order to keep the rod from rotating, as shown in Fig.

The sliding collar 7 has a tongue 9, which and prevents the collar from rotating on the rod. The collar is adapted to extend up and lit into hole 27 in arm 3'. to prevent lateral motion of the rod, and said hole may be conicel to promote entrence.

The key-lever 25 is atts shed to arm 2 of the bracketsndedapfed through an interfront pawl H, and disengnge it from the rod. Said lront pawl is held in engagement with the operating-rod by means of a spring 2%. Arm 2 also carries a. spring 56, adapted to return the koydevcr after being depressed, and adjlisting-screws 57 and 58 to adjust its movement, and may carry an antitrictionroll 22 for the weight-bar to pass over.

h'lanilcstly l have not described all the ways by which my invention can be carried out nor all the uses to which it can be put, and I do not intend hereby to limit myself to the specific mechanism herein described, as the same may be greatly modified and still be within tho scope oi my invention.

Among other things I claim broadly to have improved the lllergentheler machine referred to in that l. have provided means by which the operator can suspend the start and-stop nature. oi the machine at pleasure, have provided for the holding up of the essemblinglcvator, durto the force that ori ,;inall. carried it up. until the matrixdine lus passed out and tlu-rcupon the immediate and automatic return, provided a double holding (lBVlt'kl for the elevator-raising mechanism, and provided spr nghctuated mechanism for raising and returning the assembling-elevstoix Having thus described my invention and its use,jl claim 1.
