TABULATOB FOR TYPE-BAR-CASTING MACHINES.

Application filed January 5, 1914. Serial No. 810,529.

T 0 all whom it may concern Be it known that I, EDWARD T. VTATERs, a citizen of the United States, and a resident of Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Tabulators for Type-BarCasting Machines, of which the following is a specification.

My invention relates to type-bar casting machines, especially to machines having the general structural characteristics of the well-known Mergenthaler linotype.

It is the object of my invention to provide in a tabulating attachment of the kind shown in Letters Patent No. 77 0,341, issued to me Sept. 20, 1904, certain structural refinements whereby the mechanism may indicate with great accuracy the movements of the assembler-slide of the line-casting machine, employing for this purpose a graduated scale such as that shown in the foregoing Letters Patent and, in addition thereto, a device for indicating minute subdivisions of the units in which the scale is graduated.

Further objects of my invention are to provide means for insuring the accurate and permanent alinement of the working parts, for preventing and compensating lost motion in said working parts, for securing an even and uniform tension on the assemblerslide, for varying the tension on the assembler-slide, and for connecting the tabulating device with line-casting machines of the various models or styles now in use.

In the accompanying drawings Figure 1 is a front view of a part of a linotype machine having applied thereto a tabulating attachment embodying my invention, Fig. 2 is a plan view of the attachment, Fig. 3 is a bottom view of the same, Fig. 4 is an end view thereof, Fig. 5 is a transversevertical sectional view on the plane of the line 55 of Fig. 6, Fig. 6 is a horizontal sectional view on the plane of the line 66 of Fig. 7, Fig. 7 is a partial front view of the device with the face-plate removed, and partially a longitudinal vertical sectionon the plane of the line 77 of Fig. 6, Fig. 8 is a detail horizontal sectional view of the returnspring casing and tension-adjusting device, the section being on the plane of the line 88 of Fig. 9, Fig. 9 is a detail front View of the return-spring device, partially broken Specification of Letters Patent.

Patented Oct. 3, 1916.

away to show the interior structure, Fig. 10 1S?! detail front view of the point-dial mechanrsm, partly broken away to show the interior structure, Fig. '11 is a transverse vertical section of the point-dial casing on the plane of the line 111'1 of Fig. 10, most of the inclosed mechanism being shown in elevation, Fig. 12 is a detail horizontal section of a part of the point-dial mechanism, the section being on the plane of the line l2-l2 of Fig. 10, Fig. .13 is a detail of the yieldable connecting device for the driveshaft of the point-dial mechanism, Fig. 14 1s a detail horizontal sectional view of the tape-connector, the section being on the plane of the line 14'14 of Fig. 7, Fig. 15 is a detail vertical section of the front-slide and tape-clamp on the plane of the line 1515 of Fig. 7, and Fig. 16 is a detail horizontal section of the plunger-block and assembler-slide extension-piece on the plane of the line 16-16 of Fig. 7.

In Fig. 1 of the drawings there is shown a portion 21 of the face-plate frame of a linotype machine, the assembler-slide 22, and a part of the assembling-elevator 23. The assembler-slide is shown in the position assumed when there are no matrices in the assembling-elevator, as when the machine is ready to begin the composition of a line. In the style of machine'illustrated, the frameportion 21 is disposed immediately above the keyboard of the machine, and near the right-hand end of said frame-portion 21 there is a large cap-screw 24 which is ordinarily employed for holding the pi-tray bracket 25 which extends out diagonally above and to the right of'the key-board. The said screw 24 may be used as shown for securing to the frame-portion 21 a bracket which carries the 'tab'ulator-casing andreturn-spring device. The said bracket comprises a vertical portion 26 and

horizontal arms

27 and 28 extending, respectively to the left and right of the vertical portion. The portion 26 has a vertically elongated opening therein for the screw 24, so that the bracket may be adjusted slightly in its vertical relation to the frame-portion 21. The bracket may also be rotated more or less around the axis of the screw in order to aline the tabulator-casing horizontally with the assembler-slide. The horizontal arm 27 has in its upper surface a shallow groove into which there is slidably fitted a rectangular tongue 29 formed on the lower side of the main casing 30 of the tabulator. A screw 31 passes through a longitudinal slot in the bracket-arm 27 into the casing 30 and secures the casing to the arm so that it may be adjusted longitudinally thereon. In order to enable longitudinal adjustments of the casing greater in extent than the length of the slot in the arm 27, one or more extra threaded openings for the screw 31 may be provided in the casing, one such extra opening 31 being indicated in Fig. 6.

On the bracket-arm 28 is mounted the return-spring device which is provided in connection with the tabulator for pulling the assembler-slide back to its normal or initial position shown in Fig. 1, after it has been moved to the left from said position. It will be understood that said return-spring device is substituted for the return-spring usually employed in machines of this kind, for the purpose mentioned. Near the end of the arm 28 there is an opening therein through which a portion of a stud 32 passes slidably and rotatably. At the rearward end of the stud is a nut 33 beneath which extends one end of a flat spring 34:, the other end of said spring being secured to the bracket by a bolt 35, as shown in Figs. 3 and 8. The spring 3%: pushes the stud rearwardly and normally holds the collar 36 thereof in engagement with the front side of the bracket-arm. A pin 37 on said collar is adapted to enter any one of several small holes in the face of the arm and thus prevent rotation of the stud. the front end of the stud is a knob 38 between which and the collar 36 the return-sprin drum is revolubly mounted on the stud. Said drum comprises a hollow cylindrical body 39 having two peripheral flanges forming an annular channel between them, and a plate d0 which closes the front side of the cylindrical space within the body 39. In said cylindrical space is disposed a spiral spring 41 of which the outer end is connected with a pin 422 on the drum-body and the inner end is connected with the stud In the channel between the peripheral flanges of the drumbody is a pin 43 to which is connected one end of the tape ii, the latter preferably being a thin flexible band of steel. The other end of the tape a l extends horizontally from the lower side of the drum and enter a slot in the side of the plunger-block 45, with which it is connected by means of a small screw In the rearward side of the plunger-block is a horizontal rectangular groove and, in the structure shown, one end of the assembler-slide extension-piece 4k? is placed in said groove and secured to the block by means of a screw .1-8. The extension-piece extends diagonally in a lateral and rearward direction and the end thereof its around the front side of the assembler slide 22 near the right-hand end thereof, the extensiorrpiece being secured to the slide by a screw a9 and dowel-pins 50.

In some machines with which the tabulator may be used, the extension-piece need not be employed, and in such cases the assembler-slide may be connected directly with the plun er-block 4-5, being secured thereto by the screw 48 and by dowel-pins passing through openings 50 in the block. The spring ll being under a suitable tension, causes the tape 44-. to exert a constant pull to the right on the assembler-slide. The tension of the spring ll may be varied by rasping the knob 38, pulling the stud 32 forwardly until the pin 37 is disengaged rem the bracket-arm as shown in Fig. 8, then tiu'ningthe knob until the spring is at the desired tension, and finally reengaging the pin 3? in one of the holes therefor in the bracket-arm. The knob and stud are turned to the left to increase the tension of the return-spring, and to the right to decrease the tension thereof. The length of the spring 4&1 is such that the variation of tension therein due to movement of the as sembler-slide will be very little, so that the pull exerted on the slide will be substantially uniform throughout the travel thereof.

In the plunger-block 4:5 is a vertical opening in which is slidably disposed the plunger 51, a coil spring 52 being placed below the plunger so as to press the same upwardly (En one side of the plunger is a small handle or stem 53 which extends out through a slot in the front side of the block. T is said slot is T-shaped, having a horizontal portion and a vertical portion, both of which intersect the vertical opening for the plunger. At the upper end of the plunger the sides thereof 51 are flattened parallel with the stem 53, and when the stem is in the vertical portion of the slot the spring 52 -aises the plunger up until the flattened portion thereof extends above the upper end of the block, as shown in Figs. 5 and 7. The flattened end ot the plunger may be withdrawn into the lock by forcing the stem 53 downwardly, and may be retained in retracted position by turning the stem into the horizontal portion of the slot in the block, the plunger being thereby rotated a quarterturn.

The flattened upper end of the plunger 51 is adapted to enter a transverse slot in the lower side of the slide-block 5a which is carried on the pa allel horizontal guide-rods 5o. Said guide-rods have their end-portimis held in lugs 56 which extend down from the ends of the casing 30 near the front edge thereof. The guide-rods pass through rec tangular openings in the slide-block, the upper opening being square so as to have a four-point bearing on the rod, and the lower opening being vertically elongated so as to bear upon the rod only at the front and rear sides, as shown in Figs. 5, 7 and 15.

The front side of the casing 80 is closed by a face-plate 57 which is removably secured to the casing by screws 58. The faceplate has a rectangular opening therein extending almost the entire length thereof, the sides of the opening being rabbeted and there being disposed in the opening a transparent plate 59 of glass or the like, the plate being held in the opening against the rabbet by small elongated washers 60 of which the edges extend over the edges of the plate and which are secured to the face-plate by screws, as shown. A part of the face-plate 57 extends down past the bottom of the main casing 30, in front of the slide-block 54 and guide-rods 55, and at the lower and lefthand edges thereof has a forwardly extending flange 61 formed integrally therewith. Through the vertical portion of the flange 61 is passed a small adjusting-screw 62, and to the back side of the plate adjoining said screw is secured the end of a flat spring 63 which curves around the end of the plate over the adjusting screw and terminates in front of the plate, as shown. Said spring serves to retain in position, upon the ledge or shelf formed by the flange 61, one of the type-bars or slugs cast by the machine upon which the tabulator is used. The purpose of the slug-carrier is essentially the same as that shown in my former patent, hereinbefore referred to. The end of the screw 62 forms a gage for the left-hand end of the type-bar or slug, and the screw is adjusted so that when the end of the slug is in enga gement with the screw said end of the slug will coincide vertically with the zero (0) line of a scale 6%. Said scale 64 is graduated on a thin flat bar 65 which is secured on the inner side of the faceplate-57 by screws 66 which pass through horizontally elongated openings in the plate, from the front side thereof. Said screws may be loosened when desired, to enable a slight longitudinal adjustment of the scale-bar. The graduated part of the bar is so arranged as to be visible through the transparent plate 59.

On the front side of the slide-block 54 is a T-shaped plate 67, secured thereto by screws, and extending upwardly through a narrow longitudinal slot in the bottom of the casing adjoining the rear side of the face-plate 57. The upper portion of the slide'plate 67, within the casing, is connected with the scale-tape 68, the plate having a small rectangular projection 69 on the front side thereof, which extends through a perforation in the tape as shown in Fig. 15. The tape is held in engagement with the slideplate by means of the clamp-plates 70 and 7 0 which overlap, respectively, the upper and lower edges of the tape, and which are secured to the slide-plate by screws which pass through openings therein and into a plate 71 having threaded openings therein and disposed behind the slide-plate.

The scale-tape 68 is preferably a thin flexible steel band and has small circular perforations therein at regularly-spaced longitudinal intervals. The tape passes around drums 72 and 78 arranged near the ends of the casing, and each of said drums has in the face thereof .a pluralityof round-pointed pins 74 adapted to extend through the perforations in the tape. The drums are fixedly secured on

vertical shafts

75 and 76 by means of screws 77. The drum-

shafts

75 and 76 are journaled, respectively, in the bearing -

blocks

78 and 79. The bearingblocks have foot-portions 7 8 and 79 which rest upon the bottom of the casing 30, and the blocks are secured to the casing by screws which extend from the outside of the easing into said foot-portions. The block 79 is secured in a fixed relation to the casing, but the screws 80 for holding the block 78 pass through slots in the casing so that said block may be adjusted longitudinally. An adjusting screw 81 extends through the end of the easing into the block and is employed to move the block lengthwise of the casing to tighten or loosen the scale-tape.

The ends of the scale-tape, after passing around the drums, extend toward each other adjacent to the rear side of the casing and are connected to each other by. the device shown in detail in Figs. 7 and 14. The tapeconnector comprises a rear-plate 82 and a front-plate 83, the rear-plate having on the front side thereof an oval central lug 8t and two pins disposed near the ends thereof.

The front end-portions of the pins 85 are of smaller diameter than the rearward parts thereof, and extend through openings in the front-plate 83. The front-plate 83 rests against the face of the central lug 84 and is secured thereto by a screw 86. The ends of the scale-tape have perforations therein adapting them to fit over the smaller parts of the pins 85 between the front-plate and the shoulders at the ends of the larger por tions of the pins, the parts being so proportioned that the tape-ends will be held loosely against the shoulders. The pivot-like connections between the tape-ends and connector-plates permit the tape-ends to move more or less about the axes of the pins 85, and thus avoid possibility of any twisting or distortion of the tape by uneven tensions at the upper and lower edges thereof.

The bearing-

blocks

78 and 79 each have at the upper and lower sides thereof rearwardly extending

portions

78 and 79 in which are held the ends of guide-

rods

87 and 88 which extend horizontally and parallel to each other near the rear side of the casing.

The guide-rods are slidable through the openings therefor in the parts 78 so as to permit longitudinal adjustments of the bearing-block 78. On the lower guide-rod 87 is slidably mounted the block 89 and on the upper rod 88 the block 90 is similarly mounted. The slide-

blocks

89 and 90 are connected with each other by means of the pointer-plate, of which the form is best shown in Figs. 5, 6 and 7. The pointerplate has an upper horizontal portion 91 which extends from the front of the casing back over the top of the upper slide-block 90, a vertical portion 92 which extends down past the back of the block 90, and a hookpertien 93 at the lower end of the vertical portion. The hook-portion 93 fits in a rectangular channel formed in the rear, lower, and front sides of the central part of the slide-block 89, but is not fixedly secured to the said block. The upper horizontal portion 91 is secured to the block 90 by screws 94. In the central part of the vertical plateportion 92 is an opening in which the centerlug Set of the tape-connector fits so as to be vertically slidable therein, and in the sides of the plate portion 92 adjoining the said opening for the lug 8% are recesses through which the pins 85 pass. The pointer-plate and. slide-

blocks

89 and 90, considered as a unit, will be designated as the pointer-slide. It will be apparent that by the slidable conncction between the pointer-slide and the scale-tape, any longitudinal movements of the tape will be communicated to the slide, but slight vertical movements of the slide and tape relatively to each other are permitted, so that no binding or friction be tween the moving parts will be caused should the tape and guide-rods not be exactly parallel. The scale-pointer 95 is secured to the front end of the horizontal portion of the pointer-plate and extends downwardly therefrom, the upper portion of the pointer being adjacent to the front side of the tape and the lower part extending slightly forward and then down between the transparent plate 59 and the scale-bar 65, as shown in Fig. 5, and so that it may be observed from the front through the transparent plate as in A lg. 1.

The length of the scale 6-4; graduated on the bar is the same as the maximum travel. of the assembler-slide 22, or the length of the longest slug or type-bar that may be cast by the machine on which the tabulator is used. In the machines for which the tabulator herein shown is adapted for use, the said maximum length of slug is five inches, and, in order to conform to the usual standard of type-measurement, the said scale- 64 is graduated in ems or picas, and quarters of a pica, a pica being equivalent to onesixth of an inch. Thus the scale shown is thirty picas in length, is provided with numerical indicia in accordance therewith, and may be designated as a pica-scale.

It will be apparent that as the assemblerslide is moved to the left from its starting position by the dropping of matrices into the assembling-elevator, its movements will be communicated through the described connections to the front portion of the scale-tape 68, which will move to the left the same dis tance as the assembler-slide, while the rear portion of the scale-tape, and the pointerslide and scale-pointer, will move a like distance to the right. The scale-pointer is arranged so as to coincide with the Zero-line of the pica-scale 64 when the assembler-slide is in the starting-position shown in Fig. 1. The amount of movement of the assemblerslide being the combined thickness of the matrices dropped into the assembling-eleva tor, it will be obvious that the thickness of the matrices, or the length of the line which has been composed at any time, will be shown by the position of the scale-pointer relative to the pica-scale 64, the scale being read from left to right. The scale graduated on the tape 68 is twice the length of the picascale 64, but is divided into the same number of parts and may be designated as the double-pica scale. As the part of the scale tape that is visible through the transparent portion of the face-plate moves in the opposite direction from the pointer, the relative movements of the pointer and the visible part of the double-pica scale are twice as great as the relative movements of the pointer and the pica-scale 64. The doublepica scale is so arranged that the zero-line thereof will coincide with the upper index of the pointer when the assembler-slide is at the starting position. Thus, the total thickness of matrices in. the assembling elevator at any time may be read on the double-pica scale in the same manner as on the pica-scale 64, but on account of the larger size of the former scale the readings may be made more easily and with greater accuracy. For very accurate work, however, it is desirable to indicate movements of the assembler-slide smaller than can be read easily even on the double-pica scale.

To enable such readings to be made I provide a rotary pointer which is operatively connected with the scale-pointer mechanism so as to make one complete revolution for each movement of the scale-pointer the length of one pica. Adjacent to said rotary pointer a dial is provided on which is graduated a circular scale having twelve equal major divisions, each of which may be subdivided into quarters. Thus, movement of the rotary pointer past each of the twelve principal divisions of the dial or circular scale corresponds to movements of the scalepointer' and assembler-slide of one-twelfth of a pica, or one tvpe-measure point. For

convenience, the circular scale and rotary pointer will be herein designated, respectively, as the point-dial and the dial-pointer.

The point-dial mechanism is inclosed in a cylindrical casing 96 which is secured on the upper side of the casing 30 near one end thereof, the front of the casing 96 being disposed angularly with reference to the front of the casing 30, so as to be substantially at right angles to the line of vision of the machine operator. The front of the casing 96 has a removable frictionallyretained bezel-ring 97 thereon, carrying a convex crystal 98 through which the dialplate 99 and dial-pointer 100 may be observed. The operating parts of the dial mechanism are carried on a frame consist-ing of a circular back-plate 101, a front-plate 102 of similar form, and posts 103 connecting said plates. The back-plate is secured to the casing by screws 10a passing through the rear side of the casing. The dial-plate 99 is secured to the front-plate by screws 105, being held in spaced relation, to the plate by lugs 106 on the front side thereof. The dial-pointer is pressed onto the front end of an arbor 107 so as to be frictionally retained thereon, said arbor being journaled in suitable bearings formed at the centers of the front and back frame-plates. On the intermediate part of the arbor 107 is a pinion 108 which meshes with a gear 109 car ried on an arbor 110. Said arbor is suitably journaled in the frame-plates and carries a pinion 111 which meshes with a gear 112 carried on an arbor 113journaled in the frame-plates, as shown. On the rearward side of the front-plate 102 a spring-casing 11% is secured concentrically with the arbor 113 by means of screws 115 passing through the plate. In said casing is a spiral spring 116 of which the outer end is connected with the casing and the inner end is connected with the arbor 113. The direction of the spiral of the spring 116 is such that movement of the pointer-arbor 107 to the left, or counter-clockwise as viewed from the front of the dial, will increase the tension of the spring, and the spring when under tension will tend to move the arbor 107 and pointer to the right or clockwise. In addition to the gear 109 there is a second gear 117 which meshes with the pinion 108. Said gear 117 is carried on an arbor 118 which is journaled in the frame-plates, and said arbor also carries a pinion 119 which meshes with a gear 120. The latter gear is carried on an arbor 121 and said arbor carries also a bevel gear 122 which meshes with a simi lar gear 123 carried on the upper end of a vertical shaft 124. The vertical shaft is mounted in a bearing-block 125 which is secured on the rearward side of the front frame-plate 102. The lower end of the shaft 124 is connected with the upper end of the drum-shaft 7 6 by means of the connecting device shown in detail in Figs. 1.0 and 13, said connecting device extending through suitable vertical openings in the

casings

30 and 96. The adjacent ends of said

shafts

76 and 124 each has a spherical portion 126 thereon through which a pin 127 extends transversely to the axes of the shafts. The connecting device has two

tubular sleeves

128 and 129 of which the remote ends .are transversely slotted and adapted to pass over the spherical ends 126 of the shafts, with the pins 127 extending through the transverse slots therein. In the bore of the sleeve 129 the end of a pin 130 is forcibly driven so as to be frictionally retained therein, while the body and head of the pin fit rotatably in the bore of the sleeve 128, said pin serving'to hold the sleeves together longitudinally but permitting rotation of one relatively to the other. At the adjoining ends of the sleeves each has at one side a peripheral lug 131 which extends into the peripheral recess formed in the other sleeve between the sides of the lug thereon. Said lugs 131 form stops for limiting relative. rotative movement of the sleeves. Around the sleeves there is placed a close-wound helical spring 132 of which the ends are passed through the transverse slots in the ends of the sleeves, whereby the ends of the spring are connected to the respective sleeves. The spring 132 is normally under a certain tension such that it tends to rotate the sleeves in opposite directions and thus holds the stop-lugs 131 against each other at one side, while a sufficient force exerted on the sleeves in directions opposite to the pull of the spring thereon may rotate them until the other sides of the lugs are in contact.

The connections between the ends of the

shafts

76 and 12 1 and the

sleeves

128 and 129, being similar to ball-and-socket joints, enable the latter. shaft to be driven from the former without causing friction and bind ing of the shafts in their bearings, even should the shafts not be in perfect axial alinement with each other. The direction of the helical spring is such that when the assembler-slide is moved suddenly to the left, as by the dropping of a number of thick matrices, said spring 132 forms .a yielding element in the driving connection from the slide to the delicate dial mechanism, so that severe'stresses on the latter mechanism are avoided.

The several directions of movement of the parts of the dial mechanism caused during movement of the assembler-slide to the left, are indicated by arrows in Fig. 10. From said figure it will be seen that the dialpointer will be moved to the left or counter clockwise during said movement of the assembler-slide; that the movement will be resisted by the spring 116; and that the tension of said spring will. be increased during the movement. The said spring 116 is placed under a normal tension such that the force thereof would be sui'iicient to actuate the dial mechanism were said mechanism freed from the main tabulator mechanism, the direction of movement caused by the spring being, of course, such that the dialpointer would move clockwise. In conse quence of this arrangement of the spring 116, the gear-train and other operating connections between said spring and the scaletape 68 are always held under a certain stress, which prevents back-lash between the connecting parts, and insures perfect synchronism between the movements of. the scale-tape 68 and the dial-pointer.

In the use of the tabulator it is pref erable that spacing-matrices be provided having exact thicknesses of 2, 2-3 3 and 3:} points; and when this is done said matrices may usually be placed in magazinechannels which would otherwise not be used, thus enabling the dropping of said spacing-matrices to be controlled from the keyboard. The dial-pointer is set so as to register at the upper or zero division of the point-dial when the scale-pointer 9.5 regis ters at any of the principal or numbered divisions of the pica-scale 6i and of the double-pica scale on the tape (38. For all intermediate positions the point-dial read ing will indicate directly the number of points needed to fill out a line to the next pica division. For example, in the composition of a line requiring one intermediate alinement, such as a name and address, assuming that the address is to be commenced eight picas from the beginning of the line, the operations are as follows: The matrices for the name are run down in the usual way and occupy, for instance, five picas. Ordinary spacing-matrices are then dropped until the scale-pointer reaches a position between 7 and S on the pica-scales. As the scale-pointer passes the 7-pica lines of the scales, the dial-pointer passes the upper or index division of the point-dial scale, moving to the left or counter-clockwise. Assuming that the last of the ordinary spacing-matrices dropped fills out the line to 6-1- points beyond the 7-pica line, the dialpointer will move 6?; spaces to the left of the index division of the point-dial and will register at 5-1- on the dial, thus showing that 5% points are required to fill out the line to the place at which it is desired to commence the address. Then to fill out said space there is dropped a 3-point and a 2l -point spacing-matrix, or a l -point and a 2-point spacing-matrix, either of said pairs of matrices serving to fill out the line to the exact desired length. By appropriate combinations of spacing matrices of the thicknesses mentioned, it will be obvious that a space of any width, in half-points, from two points to a pica may be filled, using not more than three of said special spacingmatrices. For spaces greater than a pica the usual em or en spaces would be used.

The securing of very exact alinements in tabulated matter is facilitated by the use of the so-called unit-set matrices now furnished by the manufacturers of this class of machines, said n atrices being each an exact number of points or half-points in thickness. It is not ordinarily necessary to secure alinements closer than half-points, since variations of less than a half-point (about seven-thousandths of an inch) are so small as to be scarcely noticeable. It will be apparent, however, that my mechanism furnishes a means of indicating alinements much smaller than half-points, the point-dial being graduated to quarter-points and being easily readable to still smaller divisions. The machine operator, after a short ex perience with the tabulator, is enabled to tell at a glance the exact position of the as sembler-slide at any time, the number of picas from the starting point being read on the double-pica. scale, and the number of points intermediate to any pica divisions being read on the point-dial, the parts being so disposed that they may be read almost simultaneously and with a minimum of conscious effort on the part of the operator. In consequence of the ease and rapidity with which the readings may be made, composition of tabulated matter may be accomplished almost as rapidly as ordinary or straight matter.

If a linotype machine equipped with the talmlator is to be used for the composition of straight matter, so that the tabulating attachment is not required, the same may be thrown out of operation by merely pulling down the stem 58 of the plunger 51, so as to disconnect the plunger from the slide block 5%, and turning the stem 53 into the horizontal slot in the plunger-block to retain the plunger in the disconnecting position. In this connection it may be noted that the flattened end of the plunger which extends into the slot in the slide-block 54 may have a slight vertical movement in said slot and also a slight movement from front to rear, so that should the assembler-slide and the guide-rods for the slide-block not be exactly parallel the operation of the mechanism will not be thereby interfered with, nor binding or friction caused between the working parts.

The functions and manner of use and operation of the machine, as well as the purposes, manner of operation, and occasions for the use of the various adjusting and compensating devices provided in the mechanism will, from the foregoing description, be sufficiently apparent to those skilled in the art, and need not be further elaborated.

Now, having described my invention, what I claim and desire to secure by Letters Patent is:
