The present invention relates generally to improvements in the line composing type casting machines of the well known linotype class, but more particularly to that portion of the machine known generally as the slide assembly.

Heretofore, it has been the practice to disengage the clutch of these types of machines to stop the travel of the matrix delivery belt, when one or more keys have been tripped by the operator, to discharge matrices which. are in excess 01' the line previously set, in order to remove or provide space for the excess matrix or matrices. This practice not only causes delays and interrupts the continuous operation of the linotype machine, but also, under certain conditions, makes readjustment of the length of line necessary where an additional matrix is needed to complete the line. For example, where a twelve point letter like m is required to be substituted in a line in place of a six point letter like n.

It is therefore, one of the primary objects of my invention to overcome these difficulties and to provide a novel and improved construction which will permit the adding of an additional matrix or matrices to the line previously set without the necessity of interrupting the continuous operation of the matrix delivery belt and linotype machine.

A further object of the invention is to provide a simple and improved means for adjusting the width of the line or for releasing an overset line without stopping the operation of the matrix delivery belt.

A still further object of the invention is to provide a novel and improved braking mechanism for the slide bar.

A further object of the invention is to provide a novel and improved adjustment for the slide bar brake and a novel and improved means for adjusting the spring tension of the brake.

A yet further object of the invention is to provide a novel and improved construction of an adjustable clamp which automatically locks to the slide bar upon a slight movement of the clamp block in either direction to the next succeeding locking recess in the slide bar so that the clamp may be quickly and readily adjusted a minimum distance of six point (printer type measurement) one way or another without any unnecessary delay.

These and other objects are accomplished by providing a construction and an arrangement of the various parts in the manner hereinafter described and particularly pointed out in the appended claims.

In illustrating one form of my invention, I have shown the same in connection with the conventional form of linotype machine of which only a fragmentary portion of the same is shown in the drawings. This portion of the machine consists of a front plate generally indicated by the reierence character 25. Mounted on the front h from the magazine; to the matrix assembler 29'.

Extending through 'the'rront plate 25 is the usual clutch control 29 for controlling theoperation or" the matrix deliverybelt. Positioned adjacent the delivery end of the belt 2'! is the usual star wheel 35 for feeding the matrices in their normal position on the supporting assembler 28 Pivotally connected, as shownat 3|, to a lower portion of the front plate 25, is'a space bandbuffer 32 which; 77 s I H adjusted with respect to the'vertical movable member 43 to take care of this variation.

On one' side of this flange is vertically extending dove-' "tail shaped recess, as shown at. -Mounted in ing the continuous operation of the linotype machine; This mechanismcomprises a slide bracket ,25'which is secured in (spaced relation with -respect tothe front plate bybolts 26' and spacer collars 21', Reciprocally mounted on the slide bracket 25 is a-novel slide bar, generally indicated by the reference character 3t, which is preferably channel-shape in form, .as is clearly 7 shown in Figs. 11 to. l6 inclusive. Mounted within the channel portion ofthe slide'bar 3% is the usual graduatedscale in which the smaller graduations represent six point "or the. standard. printers type. This bar is reciprocally mounted in a rectangular recess 38 formed in the slide bracket 25.. The bar 34 is prevented from disof an angle member 39 secured to theslide bracket 25' by'means of screws 40. .(See Figs. 1,

The lower end of thejspring A5 is attached to ascrew 47 I cal member 43, is an adjustable stop screw 52' which is adapted to engage orcontact with my improved form of clamp for-limiting the movement of the slide bar when the predetermined; numberof matrices have been discharged to coniwhich in turn is secured to the reciprocable member ,43. The screw 4'! "extends through a vertical slot 48 formed in thelower portion or flange 4i. Thef reciprocable member is limited in its vertical movement by a stop screw 49 secured to one .side of theflange G I. This stop' screw lt-lextends through a slot 50 formed adjacent the upper end of I the member 43.

One or the essential features of the present in :vention 1 consists of the novel slide bar. and its finger trip may be depressedfrom the position shown in Fig. 15 to the position shown in Fig. 5, thereby removing th stop 55 of the screw '52 from the clamp and permitting the bar to move an additionaldistance to the left, as shown by the dotted lines in Fig. 550 as to accommodate excess "matriceswithout disengaging the clutch of the matrix delivery belt or interrupt the conwill also be obvious .from the above description; that should the star wheel, which is preferably made of fibre, become wornyor the old one replaced by a new one, the stop screw 52 may be Another essential feature of' the present invention. involves my improved construction of slide clamp in cdmbinationwith a novel con-. struction of 'slidebar in which the sliding bar has a. course graduation of six point teeth with It a 10 each of therecesses between the teethocci ipyj ing six point" (printers type measurement).

graduation or six point. at a time and at any 'positionon the sliding bar which is the finest adjustment necessary or required in this type of machine. In other words, myv novel form of clamp permits minimum adjustment of the'same with respect to the slide bar,a distance equal to oneehalf the distance between two adjacent teeth. This improved mechanism includes the slide bar 35,. which has'its' upper forward edge provided with equally spaced apart tapered recesses 550i six point width with corresponding equally spaced apart .teeth 56 between each of the rerecesses 55. These teeth are also offsix point" width. In other words, the graduations on the present slide bar are twice as coarse as those heretofore used in connection withslide' bars 5 for securing the same adjustment. Adjustably mounted in-a'rectangular recess 5l onthe bar 34 is my improved form of clamp, generally indi- -cated by the reference character 58,"which is in the form of a cubical block.

7 (See Figs. 7, 9, 10, 11, 1'7, Band 19.)

Located'in the upper portion of the clampblock "58' are two equally spaced apart recesses or slots 59 and 60'. Pivotally mounted on a transverse pin 6| andrin theslots 59 and 60,' are pawls Gland 63. 'The'inner portion of these pawls.are pointed as showni at 64 and are adapted to'be seated in the various re-" cesses55 of the sliding bar .34. These pawlsand particularly the center line passing through-the, pointed portion thereof, are spaced apart at eighteen points with respect to each other.

normally pressed 'into' engagement with the repawls inwardly of their pivots 6! on the block158.

The lower .ends of these springs are connected by means of'a pin fisto theblock 58. Obviously depressed to disengage their inner "ends from recessesi55 in'the sliding bar 34 for adjusting the The forward portion of the pawl 62 and 63 are 60 cesses 550i the slidin'g bar 34 by springs 65 mounted in vertically extending bores 65 located in the block 58. The upper endsof these springs are connected as shown at 61, to each of the 65 clamping blocks 58 in" eitherdirection on the bar 1 and'when the approximate position has been secured, as indicated by'the graduated scale35, the

pawls are released. Ifa further adjustment one way or another is required, the locked pawl may be disengaged and the clamp shifted in one direction or the other in which case the free pawl will automatically lock in the next succeeding recess, after a movement of clamps a distance of six points in either direction.

Another important feature of the present invention includes the provision of a novel and improved slide bar brake and adjustment therefor for varying the spring tension on the braking mechanism when such adjustment is required. This mechanism comprises the usual offset arm 69 of a braking lever which has its free end as shown at 10 extending beneath the assembler 29', which receives the matrices so that the same may be actuated in the manner well understood in the art, by the assembled elevator bar H, a fragmentary portion of which is shown in Fig. 6 of the drawings. The pivoted end of this arm 69 is provided with an eye, as shown at 12, and is pivotally supported on a sleeve 13, which in turn is formed integrally with a knurled collar as shown at 14. Pivoted concentrically with the pivoted portion 12 of the arm 69, as shown at 15, is a second brake arm 16. (See Figs. 6, 8, 12, 13 and 14). The arm 1.5 is yieldable with respect to the arm 69 through the medium of a coil spring 11 which has one end thereof, as shown at i8, bent at right angles with the main portion of the spring and extending through an aperture in the knurled collar 14. The other end of the spring, as shown at 18, engages a flat finger portion 19 formed on the free end of the arm 15. Formed integrally with the arm 16 and extending upwardly therefrom, is a brake supporting portion 80. On the rear side of the portion 80 is a recess 0! in which is mounted a braking member 82 secured to the brake member 80 by a screw 83. This braking member 82 is preferably made of fibre and is adapted to engage the lower edge of the slide bar 34 as clearly shown in Fig. 13 of the drawings. These brake arms 69 and 16 are pivotally secured to the slide bracket 25' by screws 84. Formed integrally with the arm 59 and extending beyond the pivot to the right as viewed in Fig. 2 of the drawings, is an extension 85. Formed integrally with this extension and overhanging the arm 15 is a lug 86 through which extends an adjustable screw 81, the lower end of which engages the upper edge of the arm 16. The adjustable'screw 81 is locked in various positions of adjustment by a lock nut 88. Obviously from the above description, it will be readily seen that should the upper surface of the fibre brake 82 become worn, the same may be compensated for by adjusting the stop or screw 81 so as to permit the arm 16 to move upwardly about its pivot with respect to the arms 69 to more efiectively brake the slide bar 34. Secured to the slide bracket 25' by means of screws 89 and arranged on the opposite side of the brake member 8-0 is a bracket or plate 90 which has an inwardly overhanging flange 9I to the under surface of which is secured by means of screws 93, a fibre brake member 92 for engaging the upper side of the slide bar 34.

The slide bar 34 is normally returned to its starting or home position as shown in Fig. 1 against the fibre block or stop 94 secured to the front plate 25 in any well known manner such as a spring 95 which has one end thereof connected to the upper end or arm 90 of a bell-crank 91. The bell-crank 91 is pivotally connected by means of a screw 98 to the front plate 25 as clearly shown in Figs. 1 and 2 of the drawings.

The lower arm of the bell-crank 91 is connected by means of a link 99 to the right hand end of the slide bar 34 as viewed from Figs. 1 and 2. Secured by means of a screw I00 to an upwardly projecting arm IOI formed integrally with the assembler slide bracket 25, is a bell I02. Pivoted on a screw I03 to the assembler slide bracket 25' is a striker arm I04 which is normally actuated in the direction toward the bell by a coiled spring I05. The lower end of the striker arm is provided with a forwardly projecting lug I06 which slides in the path of movement of a downwardly extending projection I01 secured to the rear side of the clamp block 58 by means of a screw I08 as clearly shown in Fig. 20 of the drawings.

The operation of the several features of my invention are as follows:

Let us assume that the operator of the linotype is desirous of setting the clamp 58 on the slide bar 34 for a certain width of a line, the two pawls 62 and 63 are depressed and clamp 58 is easily shifted along the slide bar to the approximate position of width of the line, after which the pawls are released, one or the other of pawls, particularly the front ends 64 of one of the pawls will engage one of the notches or recesses in the upper edge of the slide bar in the manner indicated in Figs. '7, 9 and 11 of the drawings. If the operator is desirous of shifting the clamp one way or the other, a distance of six points or the minimum width of the letter n matrix, the engaged pawl 52 is depressed and the clamp is shifted in the desired direction and when shifted the proper distance or six points either way, the

forward end 54 of the pawl 63 will automatically o0 engage the next adjacent recess 55. This arrangement reduces the time required to set the clamp with respect to the slide bar over the time that is now required for this particular operation. In this connection, it is also pointed out that by reason of the rack teeth on the slide bar being of larger or coarser form, that is the teeth 55 being of six point width and the recesses 55 being a six point width, the slide bar presents a simpler manufacturing proposition and in combination with this novel, improved clamp, secured the minimum adjustment required for this type of machine with the least possible efiort. After the line has been set by the adjustment of the clamp on the slide bar and the matrices discharged into the holding channel in the conventional manner, should additional matrix or matrices be discharged in excess of the line set so as to clog at a point adjacent the star wheel 30 in the manner shown in Fig. 4 of the drawings, the space I of the line between the slide finger 34' and the star wheel 39 may be quickly extended without disengaging the clutch 29 to stop the matrix delivery belt 21, by merely depressing the finger trip 44 from the position shown in Fig. 15 to the position shown in Fig. 5 wherein the stop 54 is lowered so as to permit the clamp 58 to move from the position shown in Fig. 15 to the dotted line position shown in Fig. 5, thereby permitting the additional matrices to be added to the line. In this connection, it will also be noted that should the star wheel 30 become worn or a new star wheel replaced for the old one, the stop screw 52 may be adjusted to compensate for any variation necessary to adjust the point at which the clamp and slide bar is stopped.

The operation of another feature which co-operates with the previously described features of my invention has to do with the novel and improved form of braking mechanism for the slide ,bar which not only permits'cthe adjustment, for r varying the braking pressure to compensate for wear on the fibre brake, but which also permits 'a quick release of the brake on the slide bar for taking'up'any excess of space the line of mat- -rices after the step has been released from the clamp to, accommodate any excess matrices (16-,

livered to the holding channel.

This 7 braking V mechanism includes an upper fibre brake member 92 secur to; thestationary bracket 90 and the spring a ated member 80 which carries the fibre braking member 82 contacting the lower V edgeof the slide bar 3%. Itwill be noted that bar so that the returning spring 95 may actuate 7 20 when there is an excess space between the slide bar finger 34 and the star wheel 30, this can be immediately taken up by depressing the finger trip l l' against the action of the coil spring ii,-releasing the braking tension on the sliding the slide ,bar 34 in' the direction towards the stop 94. The actuation of the brake member "80 downwardly does notdisturb' the position of the other brake arm Iii In this connection, it will on the fibre brake members.

noted that the spring tension I? may be ad-' also be noted that the relative positionbf the brake arm l6 respect to the brakearm 69 may be adjusted for taking care of'any wear It will also be 'justed between these two brake arms by merely releasingthe screw 3d and turning the thumb sleeve and collar it in a counter clockwise direction as viewed from Fig. 6 of drawingsand i subsequently tightening the screw 54 when the? adjustment has been secured. It will also'be observed in this connection, that the manipulation, operation and adjustment of these various features may be accomplished withconsiderable ease and without interrupting the continuous op eration of the machine. 1

From the above description, 'it will be readily. seen that I have provided not only a very simple and efiicient means for accomplishing these various operations on the conventional lincty'pe machine, but have also provided a very'simple design which expedites the manufacture and reduces the costas well as increases the efliciencyof. the
