ASSEMBLER-SLIDE ADJUSTMENT FOR LINE-GASTIIJG MACHINES.
Application filed June 10, 1925. Serial No. 36,232.
which has an upstanding finger which serves to hold the matrices together or in compact form while the line is in process of assembly, the slide being caused to advance as the matrix assembling process progresses and being provided with means for limiting its advancing motion according to the length or measure of the line to be composed, thereby iiireventing ovcrlilling of the line and being also provided with means for, causingoperation of a signal or indicator, usually a bell, to inform the compositor when the line is nearly filled.
The primary object of the invention is to provide novel and improved means whereby a single adjustment which can be made q .ickly and with facility by the compositor while occupying his usual position at the keyboard of the machine, serves to set the assembler slide for a line of any desired length or measure, to set the stopping or limiting means for the slide so that the advance thereof will be arrested when the line of matrices in process of assembly has reached the measure for which it is set, and to set the indi cator or bell-operating means so that the indicator will operate'at the correct point in advance of the completionof the line.
To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts, all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.
In the accompanying drawing Figure l is a front elevation of a portion of the assembling mechanism of a line-casting machine constructed in accordance with the preferred embodiment of this invention;

Figure 9 represents across-section on the line 99 of Figure 7 looking toward the left. I Similar parts are designated by the same referencecharacters in the several views.
The present invention is applicable generally to the assembling mechanism of linecasting machines wherein an assembler slide is employed which has a finger behind which the matrices and spacers are assembled to form a line preparatory to the casting of a type bar therefrom, the assembler slide being advanced as the assembling of the line progresses, under the force exerted on the finger of the slide by the matrices as they are successively introduced into the line behind it. The preferred embodiment of the invention is shown in the accompanying drawings and will be hereinafter described in detail as applied to a line-casting machine of the wellknown linotype class, but it is to'be understood that the invention is notrestricted to the precise construction shown as equivalent constructions are contemplated, and such will be includedwithin the scope of the claims.
In the present instance, 1 represents the assembling elevator which in machines of the linotyp-e class is guided tomove vertically so that when the assembling of a matrix line therein has been completed, it may ascend and thereby transfer the matrix line from the assembler slide to a transfer carriage which'operates at a relatively higher level in. the machine and serves to remove the matrix line from the assembling elevator and to forward the line toward the casting point. The matrices and spacers during their assembly in the assembling elevator are supported and guided therein by the rails 2, as will be understood by those skilled in the art. The matrices aredelivered from the magazine or magazines in which they are stored through manipulation of the usual keyboard, to an assembling belt 3, and this belt delivers the matrices to the continuously revolving star-wheel 4 which stacks the matrices successively in the line and advances the line in process of assembly, toward the left in Fig. 1.
The assembler slide 5 which is movable in a direction parallel to the length of the matrix line, has a finger 6 which extends upwardly therefrom into the channel formed between the rails 2 of the assembling elevator, so that this finger will occupy a position in front of the matrix line as the latter is as sembled. The assembler slide is preferably .suported on anti-friction rollers? and 8 in order to minimize frictional resistance to its movement, and the slide is mounted on a bracket 9 which is fixed to the relatively stationary main frame of the machine.
The present invention provides means whereby a single adjustment that can be easily and quickly made by the compositor, will serve to determine the limit of movement of the assembler slide to conform with any desired length or measure of the matrix lines to be composed and to correspondingly set the means which operates the bell or other indicator to inform the compositor when the matrix'line of the selected measure has been nearly filled. Preferably, and as shown in the present instance, such means comprises a revoluble member 10 having a pinion 11 fixed thereto and arranged to cooperate with a toothed rack 12 on the assembler slide so that advancing movements of the assembler slide during the assembling of a line will cause corresponding rotary motion of the member; 10, and rotation of the member 10v in an opposite direction will cause return of the assembler slide to its initial or starting position. The member 10 is preferably formed with a hub 13 which is fitted to rotate on a pin or journal 14, the rear end of which may be fixed to a part 9 of the bracket 9 by a nut,15 or other suitable means. The pin 14 has a thrust collar 16 thereon which is arranged to engage and to sustain a forward thrust when such is exerted on the member 10. The pinion 11 is preferably fitted in an annular recess 17 formed in the rear side of the member 10, and a guard flange 18 is preferably applied to the rear side of the pinion, the rack portion 12 of the assembler slide preferably operating between this flange l8 and the body portion of the member 10 and thus insuring maintenance of the working relation between the rack and the pinion 11. The pinion 11 and guard 18 may be secured to the member 10 by a suitable number of screws 19 which extend into a section 20 which provides a removable front or cover for the member 10. The member 10 is formed interiorly with a chamber 21 in which is accommodated a spring 22, this spring serving to rotate the member 10 in a direction to effect the return of the assembler slide to its initial position after an assembled line. of matrices has been removed from the assembler slide. Preferably, the spring is of coiled or spiral form, its inner end being fixed at 23 to the relatively fixed non-rotatable pin 14 while its outer end is attached, by a pin24, or other suitable means, to the rotatable member 10.
The member 10 of the adjusting means is provided with a setting member which determines the range of movement of the assembler slide in accordance with the line measure for which it is set and also determines the point during the assembling of the line at which the indicator bell will operate. Preferably, and as shown, this setting member comprises a knob 25 which is capable of to tation relatively to the member 10 for the purpose of setting it for different line measures and means is provided by which the knob is connected to rotate in unison with the member 10 during the operation of the assembler slide. As shown, the knob is fitted at its inner end 26 to rotate on a stem or sleeve 27 which projects forwardly from and forms a part of the forward scction'QO of the member 10, this stem or sleeve being fitted rotatably on the forward portion of the pin '14. A toothed clutch or equivalent device which is graduated so that the knob may occupy various positions of rotation relatively to the member 10 corresponding with the graduations of line measurement, is provided between the knob and the member 10. As shown, the forward side of the front section 20 is formed with an annular toothed clutch face 28 and the rear face of the knob is formed with a corresponding annular toothed clutch face 29, the number and spacing of the clutch teeth being such that the knob may be set in a number of angular positions relatively to the member 10 which correspond with the graduations of the line measurements. the knob for different desired line measures, a pointer 30 is fixed to one of the parts, preferably the member 10, and the other part, preferably the knob, is provided with a dial 31 having suitable graduations 32 thereon which correspond with the different settings To facilitate the setting of of the knob for the various line measures, the indicating scale on the dial cooperating with the pointer on the member 10. Means is provided for normally holding the knob in engaged relation with the member 10 so that the knob will rotate in unison therewith, and which permits disengagement of the knob from the member 10 to enable changing of the line measure setting. As shown, the hub of the knob is formed with a chamber 33 to accommodate a compression spring 34 which is preferably coiled about the stem or sleeve 27, the forward end of the spring bearing against a ring or flange 35 which may be threaded or otherwise fixed to the stem 27 and the rear end of the spring bearing against the shoulder provided by the bearing portion 27 of the knob. The action of this spring is to yieldingly force the knob rearwardly to cause its clutch teeth to engage those of the member 10 and to main tain the clutch teeth in engagement, although permitting the knob to be drawn for-- wardly when suflicient pull is exerted thereon by the hand of the compositor. whereby the clutch teeth of the knob will be disengaged from those of the member 10 and the knob while held in its forward position may be freely rotated in either direction relatively to the member 10 to resetrthe device for either a longer or a shorter line measure, as may be desired. When the knob is released after resetting, the spring 34 will act automatically to re-engage the knob with the member 10. The outer end of the pin 14 may be provided with a disk 36'to fit in the chambered hub of the knob and thus provide a steadying support for the knob while the latter is drawn forwardly for resetting purposes.
The setting of the knob with respect to the member 10 determines the limit of movement of the assembler slide during the assembling of a line. The knob has a pin or stop 37 fixed thereon, and the position of this pin around the shaft 14 which constitutes the axis of rotation of the knob. will vary with the different line settings of the knob; and as the knob rotates in accordance with the advancing movement of the assembler slide during the process of assembling a line, this pin 37 will operate, through the medium of stop means. to limit the advance of the sembler slide to conform with the line measure for which the knob is set. The stop means, as shown, comprises a slide 33 which is auxiliary to the assembler slide, it being inactive or immovable during a portion of the advancing movement of the assembler slide, but movable concurrently or in unison with the assembler slide, under the influence of the pin 37, during the final portion of the advancing movement of the assembler slide, and the auxiliary slide is arranged to abut against a stop when the assembler slide has advanced to the proper limit, as determined by the line measure for which the knob is set, the consequent arresting of the motion of the auxiliary slide preventing further motion of the pin 37 whereby further ad- .vance of the assembler slide is arrested.
The auxiliary slide is preferably mounted to slide-freely in guides 39 and 40 which. are
supported by the bracket 9, so that the auxiliary slide is located alongside the assembler the pin 37 on the knob when the pin reachesits lower position or a position below the center of rotation of the knob, and the opposite end of the auxiliary slide is formed with a head 41 which is adapted to abut against the end of the guide 39 and thus limit the movement of the auxiliary slide toward the right in Figure 1, the head carrying a projection 42 which is arranged to abut against a shoulder or stop 43 which is in fixed relation to the bracket 9 whereby the movement of the auxiliary slide in accordance with the advancing movement of the assembler slide will be arrested when the assembler slide reaches its limit as determined by the line measure setting of the knob. A tension spring 44 is attached at one end to the auxiliary slide and at its other end to a relatively stationary part of the machine, as, for example, the guide 40, this spring acting to return the head 41 on the slide against the guide 39 during the receding movement of the pin 37 incident to the return of the assembler slide to initial position but permitting the auxiliary slide to be advanced by the pin 37 when the latter advances during the assembling of a line.
The spring 22 acts constantly to return the assembler slide to its normal or initial position, and in order to avoid pressure of the assembler slide finger 6 against the line of matrices during the intervals between the introduction of the matrices therein, and thus prevent undesirable pressure of the last introduced matrix in the line against the starwheel 4, a brake 45 is provided, this brake allowing the assembler slide to be advanced Without obstruction; to an extent sufiicient'- to admit each successive matrix into the line. but acting after each successive advance of the assembler slide has been completed. to prevent retrograde motion of the assembler slide which, if permitted to occur,'would force the line of matrices in process of assembling. l' ackwai.'tlly against the star-whet-l. The brake may consist, as shown, of a lever which is pivoted to rock freely on a screw or other pivotal support l6 and this lever carries friction shoes 47 be ween which the assembler slide extendsp When the brake Hit) lill) as shown in Figure 2, the friction shoes thereon will perimt the assembler slide to move without obstruction, and this occurs during the restoring of the assembler slide to its normal or initial position; at other times, however, a spring 48 acts on the brake to rotate it about its pivot 46, so that the friction shoes thereon bear on the upper and lower edges of the assembler slide so. as to prevent retrograde motion of the assembler slide, or motion toward the right in Figure 1, although permitting advancing movements of the assembler slide, incident to the assembling of th matrices in the line, without substantial resistance by the brake. The upper brake shoe 47 is narrowed and arranged to cooperate with the smoth upper edge 5' of the slide at the rear of the rack teeth 12 thereon, thus avoiding interference with its action by the rack teeth.
Means is provided for automatically retracting the brake to rel-ease and permit return of the assembler slide to its normal or initial position incident to the ascent of the assembling elevator which transfers the complete assembled matrix line to the transfer carriage. Such means is shown in the present instance, it comprising a lever 49 which is pivoted at 50 to the bracket 9, the lever at one side of its pivot carrying a pin or projection 51 which is arranged to ride upon a cam 52 on the lower or free end of the brake lever. The opposite end 53 of this lever is in a position to be acted on and pressed downwardly by the portion 54 on the assembling elevator while the latter is in its lower or line-receiving position. 'miile the assembling elevator is in this position, the end of the lever 49 which carries the pin 51 will be held in elevated position and the pin 51 will be beyond or clear of the cam 52, so that the spring 48 may act to hold the brake in operative relation with the assembler slide and to prevent retrograde motion of the latter after each advance thereof in cident to the introduction of a matrix into the line. The'parts are shown in this position in Figure 1. When the assembling elevator ascends to remove an assembled matrix line from the assembler slide, the end 53 of the lever- 49 is engaged by the abutment 55 on the elevator and thus caused to rise and the opposite end of the lever which carries the pin 51 will descend, causing the pin 51 to ride upon the cam 52, and in so doing, to swing the brake lever from the position shown in Figure 1, into the position shown in Figure 2, the friction shoes 47 being then disengaged from the assembler slide, thus releasing the latter, so that it may return freely to its normal or initial position, the assembler slide being shown in this position in Fig. 2. The assembler slide is arrested upon reaching its normal or initial position by a stop 56 on the slide which is arranged to abut against the relatively fixed guide 57.
The mode of operation of assembling mechanism constructed as hereinbefore described, is substantially as follows: The matrices designated M are delivered to the assembling elevator from the magazine or magazines, through the operation of the usual keyboard, by the assemblerbelt 3, and the usual star-wheel 4, and the star-wheel introduces the matrices into the channel of the assembling elevator which is provided between the rails 2 thereof and behind the finger 6 of the assembler slide. As the matrices are successively introduced into the line by the star-wheel, the finger 6, together with the assembler slide, are pushed toward the left in Fig. 1 to accommodate the incoming matrices, this advancing movement of the assembler slide being opposed by the spring 22 which constantly acts to return the as sembler slide to its initial position, and the assembler slide is held'against retrograde motion, after each advance thereof, by the brake 45 which permits each advance of the slide to take place but clutches the slide and thus prevents retrograde motion thereof. During the assembling of the line, the braketripping lever 49 will be held in'it-s inoperative position, as shown in Figure 1, as the assembling elevator at this time will be in its lower position and it will hold the lefthand end of the lever 49 in its depressed position.
During the assembling of a line, the linesetting device which comprises the member 10 and the knob 25 will rotate in a clockwise direction, as viewed in Figure 1, owing to the connection maintained between the setting device and the assembler slide by the pinion 11 and the cooperating rack 12, and as the knob 25 is held in clutched relation with the member 10 at this time by the spring 34, the pin 37, which rotates with the knob, will advance through an arc, the length of which is detcrmine'dby the setting of the knob relatively to the member 10, until it reaches a position to engage the righthand end of the auxiliary slide 38.
During the first part of the advancing movement of the assembler slide incident to the assembling of the line, the auxiliary slide 38 will remain stationary while the assembler slide advances, but as soon as the pin 37 engages the end of the auxiliary slide 38, the auxiliary slide will be picked up and caused to advance concurrently or in unison with the further or continued advance of the assembler slide, and as the projection 42 approaches the stop 43 its distance therefrom will afford a visual indication of the length of the unfilled part of the line. The concurrent advance of the assembler slide and the auxiliary slide will continue until 10 which rotate therewith will be arrested;
As the knob 25 and member 10 at this time are in clutched relation and the member 10 is connected to the assembler slide through the pinion 11 and rack 12, the arresting of the motion of the pin 37 by the auxiliary slide 38 will arrest the further advance of the assembler slide and its finger 6. Overfilling of the line is thereby prevented.
When the line has been completed, the assembling elevator may be caused to ascend, in the usual way, to transfer the matrix line to the transfer carriage. The ascent of the assembling elevator causes the lever 49 to act so that the pin 51 thereon will ride on the cam 52 and thus shift the brake 45 to release the assembler slide, whereby the latter is permitted to return to its initial position under the influence of the spring 22, as shown in Fig. 2, and the anticlockwise rotation of the setting device incident to the return motion of the assembler slide retracts the-pin 37, thus permitting the auxiliary slide 38 to return to its normal or initial position, as determined by the abutment of the head 41 on this slide against the guide 39, under the tension of the spring 44. When the assembling elevator again descends to its lower line-receiving position,
the lever 49 is again operated to release the pin 51 thereon from the cam 52, thus permitting the brake to act on the assembler slide under the influence of its spring 48.
The limit of advancing movement of the finger 6 of the assembler slide determines the length or measure ofithe' matrix line which the assembling elevator may receive, and this limit of movement is determined by the length of the are through which the pin 37 may swing until arrested by the engagement of the projection 42 on the auxiliary slide 38 with the fixed stop 43. The length of the are through which the pin 37 may travel, commencing with the beginning of the composition of the matrix'line and ending with the arresting of the motion of the auxiliary slide 38 by the engagement of its projection42 with thefixed stop 43, is determined by the position in which the knob 25 is set relatively to the member 10. For example, in Figure 3, the knob is set relatively to the member 10 so that the pointer 30 on the latter member registers with the numeral 14 on the scaleof the dial on the knob. With such setting of the knob, the pin 37 will be enabled to swing through an arc of a length which will enable the finger 6 on the assembler slide to advance during the composition of the matrix line until aline having a length or measure of fourteen ems has been composed. When it is desired to compose lines of greater or less length, it is only necessary for the compositor to grasp the knob 27 and to draw the same forward in opposition to the spring 34, thus disengaging the clutch teeth 28 and 29, and to rotate the knob relatively to the member 10,
while the knob is held in its forward position, until the numeral on the scale 32 corresponding with the length or measure of the line to be composed, is opposite to the pointer 30, whereupon the knob may be released and the clutch teeth 28 and 29 will be caused to re-engage by the action of the spring 34. Such adjustments of the knob set the pin 37 at different distances away from the end of the auxiliary slide 38 as the starting points in the travel of the pin 37 and thus vary accordingly the distance through whichthe finger 6-on the assembler slide may travel before it is arrested.
The setting of the knob to determine the line measure may also serve to set the device which operates the bell or other means usually employed to indicate to the compositor when the line of any given measure has been nearly filled. For example, a bell ringing device 58 maybe carried on or otherwise actuated by the auxiliary slide 38, this device being operative to sound the bell 59 when the filling of the line has approached within a predetermined point of completion.
The bell ringing device 58 as shown comprises a hammer or clapper which is pivoted at apoint intermediately of its length to the bracket 9, as by a'shouldered screw 60, the hammer having on itsleft-hand end an overhanging forwardly-extending inclined flange 61; A gravity pawl 62 is pivotedto the head 41 of the auxiliaryslide, this pawl having an inclined rearwardly-extending flange 63 at its lower end which is positioned to engage the flange61 on the bell hammer as the auxiliary slide moves toward the left, thereby first lifting and thenreleasing this end of the hammer so that the tensioned spring 64 will cause the opposite end of the hammer to strike and sound the bell. The pivoting movements of the pawl 62 are limited in both directions by suitable stop pins 65 and 66, the pin 66 acting tosustain the pawl in position to raise the flange 61 on the hammer during the left hand stroke of the auxiliary slide, but the stop pins will allow the pawl to have a latching or idling movement dur-V ing the right hand movement of the auxiliary slide which returnsit to normal position. v
By operating the alarm bell or other indicator in thisway, the bell orindicator will assembling mechanism is set, as the auxiliary slide 38 will be picked up and advanced by the pin 37 always at a given point in advance of the limit of movement of the finger 6, and this relationship will not be altered or disturbed by setting of the knob for different line measures.
