Letters Patent No. 436,532, dated September When a line has been assembled in the 16, 1890. It should be understood, however, block I, the latter is raised vertically between that the said invention isnot limited to linosuitable guides to the level of the shifter,

For that reason and known in America as the first elevator, for the purpose of this specification the apwhich head is made after the manner of the pellatives matrix and matrices are to top of the assembling-block I to receive the 0 be understood as including both the female saidline. This transporter N has a vertimatrices and the male dies above mentioned. cally-reciprocating motion first down to the The accompanying figures are to be taken mold-wheel 0., against which it holds the comas part of this specification and read thereposed line while the linotype is being cast, with. and then up above its original level to 006p- 5 In the drawings, Figure 1 is a detail front erate with the transferring-arm of the diselevation illustrating the first part of the intribuier X (the position shown in dotted vcntion. Fig. 2 is a detail longitudinalseclines in Fig. 3) and back again to the level tion taken along the line 2 20f Fig. 1; Fig. 3, along which the shifter L L works, (the a front elevation of a portion of a Mergenposition shown in full line in the same figure.) Ioo Now, seeing that the elevation of the assembling-block I is under the control of the operator, without reference to the travel of the transporter N above mentioned, it occasionally happens that he sends that block upward toward the shifter L L- soon enough for the latter to seize the composed line in question and move it through the guide-block M before the transporter N has been returned low enough to receive it. The consequence is that that line, instead of being delivered by the shifter into the head of the transporter or first elevator N, is thrown out anctpied. The object of this first part of the invention is to prevent an accident of the kind just mentioned. This object is effected by a stop adapted to lock the assembling-block I down in its lowest or composing position and to be moved out of its path only by the descent of the vertically-reelprocating transporter I that is, when it is on its way to aline itself with the shifter L L. Thus the assemblingblock I is kept down in its lowest or composposing position all the time that the head of the transporter N is above or below the level of the slot in the guide-block M. The combination which I prefer to use (see Figs. 1 and 2) consists of a detent I pivoted on the face of the guide-block M, and a slide 1 adapted to work on suitable guides Win a horizontal slot 1 in the said guide-block by having one end pivotally connected with the adjacent end of the detent I and the other, 1 protruded by a spring I into the path of the transporter-N. IVhen a certain and properlyplaced lateral projection 1 011 the transporter N engages the spring-protruded nose 1 of the slide 1 it pushes the latterin against its spring 1 thereby rocking the operative nose of the detent I out of the upward path of the assembling-block I and freeing the latter, as indicated by the full lines in Fig. 3. The corners of the nose 1 are rounded or tapered off to provide for its giving way before the projection 1 The contact of that projection with the nose I during the upward motion of the transporter N rocks the detent I it is true, but the consequent motion is only an idle one.

The second part of the invention relates to the cleaning of the cutting edges of the trimming-knives N (See Figs. 3 and t.) These knives stand in a vertical position parallel with each other and edge on to the rear not far from and parallel with the path of the assembling-block I. The cleaning above mentioned is done by a wiper 1 In all machines heretofore used in America this wiper has been attached to a vertically-guided rod operated intermittiugly. In practice it is found that under certain conditions, particularly when liuotypes with overhanging two-line letters are produced, there is a liability of the ejector to advance before the wiper is removed from its path, the result being the stoppage of the machine, the destruction of the wiper,and occasionally other in j ury to the machine. To overcome these difficulties, Inow attach the wiper I to the curved arm 1, projecting downward and outward to the left from the assembling-elevator I, the rising of which sets various parts of the machine in motion, as usual. The arm and wiper stand normally below and entirely clear of the knives and other parts, as shown in Fig. 3. Then the assembling-elevator is lifted with the composed line preparatory to the transfer of the line and the starting of the machine, it carries the arm I with it, thereby causing the wiper to pass upward between the knives and the mold and to immediately return to its original position as the assembling-elevator descends. The movement of the elevator occurs at such time in relation to the movement of the other parts of the machine that it is impossible for the wiper to stand in the path of the outgoing slug, the ejector, or other parts of the machine, so that collision between them cannot occur. The arrangement shown is exceedingly simple and cheap and has also the additional advantage of giving to the wipera long movement, so that it is adapted to cooperate with the longest knives required in practice.

The third part of the invention (see Figs. 5, (3, and '7) relates to improvements in the distributer. An improved form of the more important organs of the latter is illustrated in detail in the specification of Letters Patent of Great Britain No. 26,648 of 1896. These organs are (a) the transferring or verticallyswinginglifting-arm, commonly known as the second elevator, and a pusherby which the matrices are moved from the transferringarm onto the introductory supporting-rails of the distributer, up to a stop thereon, and (b) an automatic lifter by which the leading matrix is lifted above the stop and preparatory to their engagement by the threads of (c) the usual horizontal traversing-screws of the distributer, which carry the matrix along until it is dropped into its own propergroove in the magazine.

25 is the free and operative end of the transferring-arm or second elevator. It is a short length of rail of the same cross-section as the V-shaped notches in the tops of the matrices Y, so that when the line of matrices is carried endwise the matrix-teeth will engage the teeth of the bar or rail 25, so that the matrices will be suspended therefrom, as in the ordinary Mergenthaler machine. The transferringarm is a lever having its fulcrum in the rear of the machine, upon which it has an intermittent reciprocating motion in the vertical plane under the control of a suitable cam, the construction and mode of action being essentially the same as that of the arm marked T in United States Letters Patent No. $36,532, to O.Mergentl1aler, dated September 16, 1890. \Vhen a composed line of matrices is ready to be transferred to the distributor, it finds itself in the head of the transporter or first elevator N, the latter then standing i n its highest position. (Illustrated by the dotted lines in Fig. 3.) At this time the matrix-line is supported opposite the end of the rail iof the lifter, so that the line may be pushed endwise to the right out of the transporter N and into engagement with the lifter-rail t.

W is the pusher for effecting the transfer of the matrix-line to the rail t. It is fast to the end of a slide which has a reciprocating horizontal motion in a suitable guide. Neither of the latter are included in the figuresQ The motion of the pusher W is from the position illustrated in Fig. 5 to outside the rail 25.

t is a second but stationary short length of rail, being held fast to the lift-box T, through which the matrices are pushed by the pusher 7' along introductory supporting-rails #17". Each rail has a shoulder 25 or 6 the four shoulders standing in the same vertical plane and together constituting the stop above mentioned to limit the advanceof the line toward the distributer-rail.

5c is the automatic matrix-lifter to lift the foremost matrix of the line clear of the stopshoulders, so that it may be carried forward horizontally to the distributer-rail and screws.

or is the distributer-rail, of the same crosssection as the rails t t, and onto it each matrix is delivered to be traversed therealong by the three screws m m 00 The lifter 0c is a vertical dog receiving a reciprocating vertical motion from a spring x and a cam projection 00 It and the stop are so proportioned and positioned, respectively, that when the former is at the bottom of its stroke it stands under the leading matrix, then held in contact with the stop by the pusher WV.

The topintroductory supporting-rails i are continued from the stop for a short distance between the traversing-screws, their edges being inclined upward, as shown at i in Fig. 5. The mechanism just described with reference to this third part of the present invention are as heretofore, their action being, in brief, to lift the matrices one at a time between the successive threads of the screws, so that the latter may carry them to the right along the distributer-bar. They are introduced into this specification only to show the cooperation of the devices forming the'third part of myinvention. The object of this latter is to insure the engagement of the leading matrix by the threads of the distributerscrews, and that object is attained by the following means: the two top distributer-screws 00 00 used to overhang the leading matrix Y. hen they did, that matrix was lifted up with in their zone, but sometimes not high enough to clear the bottom shoulders 25 A matrix in that predicament would most likely be bent and stop the distributer, thereby necessitat ing the personal attention of the operator to clear the latter. The threads of the two screws above mentioned now stop at the right of (looking at them from the front of the machine) the vertical path of the said matrix, as

clearly shown in Figs. 5 and 6 According to the present invention the lifter at does not place the matrix within the zones of the distributer-screws. It lifts it high enough to stand opposite to, them, and then a supplementary pusher pushes it horizontally up to the threads of the said screws. This supplementary pusher consists of a horizontal reciprocating bar W having a transverse piece W adapted to act behindthat is to say, on the left of-the top of the lifted matrix and to be returned to its first position, so that it I mayact in turn on the succeeding matrices, which are lifted one after another before it.

The supplementary pusher may be and ad vantageously is provided witha transverse lug W, carried by a leg W which is fast to and depends from the said pusher, the said lug being held in a proper position for engaging the matrix near its foot at the same time' that the transverse piece W engages the top of it. The function of this lug W is to prevent the matrix from swinging out of the perpendicular during the time that the supplementary'pusher is dealing with it.

It is obvious from the foregoing what must be the extent and time of the two motions of the supplementary pusher. Those motions may be imparted to it by any suitable and convenient mechanism. The one illustrated of the lift-boxand which has the bar w fast to it, and a tension-spring W. This spring pulls from a fixed point upon one end of the rod W and keeps the opposite end in touch with the cam-surface W the tension of the spring W putting the supplementary pusher through its operative stroke, and the projection of the cam-surface W returning-it to its first position for the rise of the next matrix.

To further safeguard the proper motion of the leading matrix up the inclines i above mentioned, there is .combined with each introductory rail a spring-detent W which yields before the advancing matrixand locks behind it, thereby obviating any tendency to slip back. This detent is shown in Fig. 5 as being a horizontal one fixed to the outer face of the rear side of the lift-box T, its nose reaching the respective matrix through a hole W in the said side. The rise of the camsurface W is such that the pusher-plate is retracted to the right of the rising matrix and then permitted to move to the left sufficiently to carry the thickest matrix within the grasp of the detent \V and into position to be engaged by the threads of the screws. The mothe screw-threads and of the next matrix to be lifted.

The fourthpart of the invention is illustrated in Figs. 3 and 8. It relates to mechanism for preventing the injection of molten metal into the mold in the event of the transporter N, above mentioned, failing to present the composed line to the mold properly. Hitherto the forward motion of the mold-wheel O has been relied on to throw the casting mechanism out of gear whenever the transporter has so failed. The details of the mechanism by which it accomplished this are reproduced here from the specification of Letters Patent No. 436,532, dated September 16, 1890.

(r is a vertical bar suspended by a spring a from the vise frame P, and so long as it is in its normal position it projects its head (L23 above the abutment P in the downward path of the head of the transporter N on its way to the casting position.

(1 is a dog on the rear edge of the bar a and a is a plate adapted to slide horizontally to and from the front of the machine. That plate is pushed to the rear by a spring pushing on an ektension of it, as illustrated in Fig. 8, and to the front by a forward motion of the mold wheel 0. The bar 6023 stands within a slot in the plate a long enough to permit of the latters motions. The normal position of the bar (fi -the one due to the pull of the spring a keeps the plate (1 opposite the dog The transporter-head fails to present the composed line properly if it does not come down upon the abutment P. If it does not come down so far as that, the front face of the mold-wheel 0, coming up to the plate a pushes it against the dog (L25 and so swings the bottom end of the bar a to the front far enough to make it turn the lever a on its fulcrum. The motion of this lever is adapted to throw the casting mechanism out of gear. It can be put into gear again by the hand-lever a. If, on the other hand, the transporter-head does come down upon the abutment P, it depresses the bar (1.23 low enough for the plate a to miss the dog (L25 when the mold-wheel O pushes that plate to the front, so that the slide of the said plate to the front leaves the bar a alone. In either case, the spring of the plate a returns it to its normal position. One of the forward motions (the one occurring in advance of the ejection of the linotype) of the mold-wheel 0 takes place when the mold 0 in use is on the right hand of the axis of the wheel 0, (see the right-hand dotted lines in Fig. 3;) but as it is now a very general practice to fit a wheel 0 with as many as four molds o separated from each other by a quarter of a circle, and as the wheel 0 makes two motions about its axisone of ninety degrees and one of two hundred and seventy degreesthere is one mold at the bottom, as

shown in the figures, when the above-mentioned mold in work is in the right-hand position above mentioned. The presence at that moment of the one at the top may be ignored. It is inoperative as far as the present invention is concerned. Each mold, with its matrix -alining plate 0 projects from the front face of the mold-wheel O for an appreciable distance, (see Fig. 8,) so that when that wheel comes forward into position for the newly-east linotype to be ejected from the mold the bottom mold swings the bar a forward against the lever a and puts not only the casting, but also the ejecting and other mechanisms, out of gear, they all being driven from the same first-motion shaft. It should be borne in mind that when the bottom mold swings the bar a the transporter-head is away above the abutment P.

As the above-described mischievous action of the bottom mold was caused by the rising of its projection from the mold=wheel face, the combination,with the said wheel, of studs capable of an adjustable amount of projection has been tried; but the necessarily-frequent readjustment of them was found to be a nuisance. Hence it became necessary to devise some mechanism by which the moldwheel,with a mold-block at the bottom,whenever it comes forward to the ejecting position should be prevented from pushing the bar a forward.

According to the present invention the bar (1.23 and the parts connected with it are not interfered with, but advantage is taken of the upward motion of the transporter N, that being the motion which immediately precedes the above-described downward one upon the abutment P, to pull the bar a down, so as to keep the dog 04 below the plate 00 during the above-mentioned forward motion of the mold -wheel 0. Accordingly there is provided a connection between the transporter or first elevator N and the bar (1 It consists of a trip-lever N having its fulcrum upon the vise-frame P-a stationary part of the machine. The rear end of the said trip-lever engages with the foot of the bar a through a stud N projecting laterally therefrom, while the front end of it stands in the upward path of a suitably-positioned portion N of the transporter N. Although the bottom mold-block 0 comes nearly up to the plate a, the portion N engages the lever N and pulls the bar (1 down, keeping the dog below the plate (1 until the bottom moldblock 0 has been moved back again. Either the stud N or the lever N must obviouslybe provided with an automatic releasing device to allow of the transporter N passing the triplever N on its downward travel again. The connection illustrated indicates that the front end of that lever will yield before the portion N and that it will be returned to its normal position ready for workby the greater weight of the rear arm of it.
