To all whom it may concern:

Be .-it,.known that 1,,CHARLES T. LIBBY, a citizen ofthe United States, residing at Portland, in the county of Cumberland and State v i I of Maine, have invented certain new. and useful improvements in Linotype-Machines;

[,cleai', full, and exact description of the inven- 5 {.tionj, such as will enable others skilled in the. m art Ito which-it appertains to make and use Ithesaine. 1 F 'Bhis invention relates to improvements in maibhines of the general character of the socal fed kif lviergenthaler linotype -'machine I 5 shown and described in Letters Patent of the United States N 0. 436,532, dated'September 16, 1890.

It relates to means for reciprocating the assembling-elevator by automatic actuating 2o mechanism set in motion by the operator each time it acts.v i

It also relates .to means for reciprocating the assembling-elevator by automatic actuating mechanism that runs continuously and 2 5 independently of the operator.

' It also relates to means' for changing. the machine from the former class to the latter and back again.

It also relates to means for controlling the go automaticactuated mechanism and for bringing it into action at the will of the oper-. ator. 1 i It also relatesto certain details of construction hereinafter, described and specifically 5 explained. f

I he existing machine is started b the linedelivery carriage being released b the putting up of the assembling-elevator, which the operator does by a hand-lever each time he 0 has assembled a matrix-line, and the machine automatlcally stops after casting the line thus sent up unless the next line has already been sent up, in which case the startand-stop mechamsm of the machine is thrown out and its main driving-shaft in-.

stead of stopping runs continuously. By my. improved mechanism the assembling, elevator is putu automatically and is either set in operation ythe operator each time he 'hasassembled amatrix-lineor at his option,

thel-ine-delivery-oarriag'e shaft on its return throu h intermediate mechanism starts the J assem ling-elevator, thus making the machine'constant running irrespective of "the I Y Y enough to keep theifriction-diskfroinwcom- L ng off and allowingjus't'plaj enough onrthe i-operator. e In the. ;drawings herewith-accompanying Specification of Letters Patent. Application med m 23, 1903. Serial m. 166.651.

' and-TI do hereby declare the following to be a bling-elevator for operating said releasingbalancing-spring, and P the keyboard-driving shaft. the same and operate. in substantially the idly-thereto a friction diskh large diameterfor .thel sake. ofgreater efl'i- Patented o afa, ises.

and forming a part of this application, Figure 1 is a perspective view ofa portion of the Mergenthaler machine, showing my improvements appliedthereto, Ethe position of the several parts being that which they occupy at the instant the assembling-elevator releases the line-delivery carriage. F ig- 2.is a

similar view from anotherposition. Fig. 3

is a plan view of the two rods, bracket, key lever, cam,.&c. Fig. 4 isa detail'elevation view showing the latch and back rod .with their connections. Fig. 5 is a detail sectional view of the device for adjusting .the tensionspring of the forked lever-. --Fig.- 6 is a plan view of the frictional driving mechanism, and Fig. 7 is a vertical sectional view taken immediately in front of rod 514.

Same reference characters referflto like parts.- e T k In said drawings, A: represents the base; B, the front of the frame; 0, the line-delivery carriage; D, the line-delivery carriage lever; E,.the line-delivery-carriage shaft; F, the assembling-elevator; .G, the keyboard; H, a pivoted latch for retaining the line delivery carriage; I, the line-deliverymarri'agereleasing pin; J, the needle on thezassempin; K, the hook for supporting the assem bling-elevator; L, theassembling-elevatorreleasing bar; M, the assembling-elevator le ver, and N the assemblingwlevator-lever link; 0, the assembling-elevator counter- 9. These parts may be substantially same, manner as in the aforesaid Mergenthaler machine.

In carryin out my invention I substitute '5 for the hand eon the right-hand-end of the assembling-elevator lever and T attach, rig- In the end of the lever I fix a stud 2, on which'I place a counterpart friction-disk 3,1nadeipartof a too pulley and driven constantly by a belt 4 om a grooved hub 5 on'the. shaft used to drive the keyboard connections, asinthe existing machine. Thedisk-faceLI: make ofciency, and the neck or :hubibetwe'en' the disk portion and the. pulley ..end.'. -I .-make small to adapt it to the forked lever, herein; after described,; In the endof= thastmLI place a capSc1'eW.=.-fi, 'with' a; head large out of action.

square-cornered, so as to be nicely held by the angles of the two rods described below.

I attach to the forked lever two spiral springs 10 '10, one on each side of its stud and both anchored to the keyboard. The front spring 10 I makeminutely adjustable v by means of a nut 11, having a notched disk held at any. desired point by aflatspring 12, screwed to the top edge of the lever and. adapted to fit into the notches, this nut work-' -ing on a threaded hook 1-3, passin through a plain hole in the lever, with t e spring hooked thereon. The stren th of these two s rin s I adjust so that'tlie front oneis htIy more efficient than the back one, the

difference being just enough to make the fric- I tion-disks bite enough to raise the assembling-elevator and at the end of the trip bring back the front rod, as hereinafter described. When thus adjusted, the slightest obstruction or the weight of the operators hand on the assemblin elevator is sufficient to make the fIlClJlOIl-(llSkd slip until the obstruction is removed. I I

As an aid to lightness of movement and for additional adjustment to the weight of different-length matrix-lines I retain the assembling-elevator balancing-spring and its connections as in the existing machine, only ate taching it to the assembling-elevator-lever shaft at a shorter radius, so as to have its tension more uniform over the different positions of the assembling-elevator and making it stronger, so asrnot to reduce its. efficiency when I reduce its working radius.

Through the keyboard, back of the space- "band bar and above the space-band lever, I

extend right and left two rods 14 -15, partly resting in their holes through the sides of the keyboard and partly supported by spiral Y springs, two each, all anc ored tothe t6p edgesof the keyboard sides, the front-rod springs 16 16 extending from their anchor age downward and leftward to their points 9 attachment to the rodand having strength enough only. to:pro1n tly shift the front rod to the right when re eased by the key-lever below mentioned, the back-rod springs 17 17 extenrlihjg from their anchor age downward and rightward to their points 0 attachmentrto the rod and having strength .i

enough not merely to shift the back rod to the left but also to )ull the back end of the forked lever to the left against the preponderate force of .its tension-spring. The right-hand end of both rods I bend downward in a right-an led hook and arrange them to hook over t e top edge of the back end of theforked lever. The laft-hand ends of the two rods are adaptedto be operated the front one by a key-lever, the back one-bythe line-delivery shaft, as below described" The left-hand end of the back red I bend at slightly less than right angles, reaching up;

ward and slightly backward, so as to engage;

an eccentric screw 18, which I place-births" end of the line delivery shaft or hub-of the v linedelivery lever, on the top edge and slightly to the leftof the'center when the shaft is in its rightward position, so that the last rightward movement ofthe stud will rise' the back rod to keep it from range to rest lightly on top of the bracket below mentioned, and on the top of the red I cut a notch 14, ada ted to be engaged. by the back end of the eydever 21, pivotally mounted on the bracket, the front end reaching to a point convenient to he touched and pressed down bythe operator. 1 The back end of the key-lever is provided with a spring 22, tending to pull it down into its notch in the front rod. Also at the left end I place two spurs, one, 23, reaching u ,where the 0 erator can conveniently pus 1 it to the let, and thereby throw off the power and latch the front rod over in any emergency, the other, 24, reaching'downward and beveled downwardly and leftwardly, the face of the bevel adjusted to lie in the path of an exten sion 25, which I place on the assembling-.ele-

vator lever when the front rod is to the right.

The extension I fasten to the lever by set screws in slotted holes, so that the -extension can be adjusted upward or downward to the point that will throw off the friction-disks just-"as the assembling-elevator arrives up.

the keyboard is adjusted to "prevent the rod I and its bevel face passing too far to the right.

The bracket 27, which fastens to the frame,

of the machine, preferably having an arm at the bottom end reaching to the right, so as to fasten by the same screws that hold the keys board in lace, is provided withla' spur 28, reaching ownward, opposite and to the-right of the beveled spur on the front rod,so placed that as the extension goes up it passes paral- Tbpin 26 through the front rod to the left of.

lel with and close to it, and thus is adapted to take the side thrust and insure uniform action when the extension enj ages the bevel face and forces the front rod hack to the left, A similarspur 29, reaching 11 ward t right of the back end of the rey-le close to it, is adapted to take the pul the assembling-elevator'l 'pivotally mount a latch47, adaptedto latch under a corner of v the assembling elevator when in its higher position and, hold it up. Abovesaid latch I lace. a fiat spring t8, tending to hold said atch inengagementl Nearthe bottom of I .the frame l-plvotally mount a lever 49, with 'one end adapted to engage said latch adversely to said spring, the other end'carrying an antifrictionroll 50, en aging a cam 51, which I place on the endo the line-deliver shaft. The arm of the lever carrying the r0 1- is offset backward and leftward in order to bring it'into a"wor king relation with said shaft. Said cam I make with two faces, one adapted to hold the latch clear of'the elevator, the other to hold it from turning too far,

"underthe elevator. The step between these two faces I place so as to act at themoment ravity, the friction-disks apart,

when the lineof matrices hasqr'pass'ed clear of the elevator. This device is additional to the assembling-elevator hook on the existin machine, wh ch [add byreason of the lia ility ofthe lattervtofslip ofl, I

Theinachi' e thus constructed may be op ated in three. w aysi First, when the operator touches the key every time a line is ready. In thiscase the machine is in ready osition' whenthe'front rod islatched to the left, the backrod held to the right by the eccentric screw, the elevator stayin down-by iield apart by the frontjrod. The operator touching the key when his line isr'eady raises the back end of the key leve'r," which-releases the front rod and that in turn. releases the forked lever,.

which thereupon presses the friction-disks to,

gether,f carry1ng the elevator up. As the elevator reaches its upward limit the needleJ hits the iilovable 'pin in the line-delivery carriage, which in turnengagcs andlraise's the 4 line-delivery carriage latch, releasing it. At

the same instant the extension on the assembling elevator lever comes to hearing between the beveled lug on the front rod and the straight lugonthe bracket, thereby forcing the front rod to the left and letting the fricmatrices has passed out of it.

tion-disks apart, The elevator stays u supported byits latch "and hook until the ine of At this point the-releasingrba'r knocks off the assembling elevator hook and the cam throws out its latch ,releasing the assembling-elevator,which falls by gravity, its'fall-jbroken by its balancing-spring, as In [the existing machine-l The eccentric screw'is passing an idle course with the back rodf left free, which thereupon is pulled to the left b'y -itssprings-enga i gthe the main; to the left'ef rod. All parts are now again in readyposiscope of my invention and likewise the auxsembling-elevator lever the key-'leverdropped i into its notch, latching it. As the line-de- 7io livery'shaftreturns, the eccentric screw en:

ages the back rod, pushin it to the ri' ht and eavi'ng'the forked'leverhe (1 only byt e front tion. '75 The second method of operation is when 1 the operator hits the key before the -line-de livery carriage gets back. At such time the back rod is to the left and; holding the friction-disks apart, as the eccentric screw is 80 away from the backrod; The 0 erator touches'the key, raising the back en of the key-lever. The front'rodspringsto theri ht; but the friction-disks remain apart, eld' apart by the back, rod. This situation con 85 tinues until theline-delivery shaft returns. The eccentric screw then engages the back rod, forcing it to the right and the elevator starts up. The situationnowis the same as if the elevator had been released by touching the key with the line-delivery shaft back.

The third method of operation is when the key-lever is locked out, therebyleaving thefront rod idle to the right, except when the 1 assembling-e1evator-lever ext'ension holds it 5 to the left. ,When the elevator starts down, i the elevator-lever extension passes down-and the front rod passes to the right immediately, 'not being latched by the key-lever, which is 1 too locked out. This leaves the friction-disk controlledonly by the back rod. The opera- -tion under this condition resembles the-sec lever, thereby bringing the front rod. again into action, by which step an instant change to to the first "method of operating the machine is effected. i f e The scope of this ap lication, generally speakingis (1) friction- 1sk adapted toraise t e assembling-elevator; (2) var ing form ofmy devices for coordinating tiie elevator-.7 raising mechanism to the general machine movements ada ted to-mechanism driven from a constant y rotating pulle (3) vary-v ing form of my double-controlfing devices 15 adapted like 2; (4) device for elevator-raising mechanism driven from a constantly-r0 .tating pulley adapted to disconnect it .when

the elevator has been raised; (5) varying form of device for locking the elevator up until cleared by the matrix-line.- "An equivalent means which may be substitute forthe spe cific devices herein shown for these purposes,- all of which are equally within the spirit and I iliary mechanism for regulating and controlling the main features of my invention may be greatly varied, and I desire not to be lim ited in these respects otherwise than as specifically setontin the claims.

The advantages of my improved machine are as follows: It is optional with the opera-' tor to haveit either a constant-running or a start-and-stop machine. 'Iheformermethod 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 1;

e labor and nervous strain of putting up the assembling-elevator and watching the I ,thermore, operators who are 'otherwise'un movement of the machine for the proper time of doing so,- in fact having nothing left to do but to be sure their line is set before the elevator goes up and then enjoying an instants relaxationand an opportunity to glance'at co ywhile the assembling-elevator automaticaly goes up and returns. Furable to set lines to the full speed of the machine will have their speed increased, because my improved machine Will save all llllZGII'llP tion of their attention to copycaused by: using the hand lever to put up the assembling-elevator and the time while the elevator is passing up and back will enable them'to be i the assembling-elevator, devices for connectin the assemblin elevator with ower mechanism, a deviceior antomatically disconnecting the elevator from the power mech- Y anrsm, and a counter device tor regulating the return movement of the elevator.
