Specification of Letters Patent.

Patented May 21, 1918.

Application filed October 6, 1914, Serial No. 865,399. Renewed larch 21, 1818. Serial No. 223,862.

To all whom it may concern:

Be it known that I, Gnonon E. MAnLA'r'r, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

My invention relates generally to line casting machines, but more particularly to the line determining elements of such machines, and has for its object the provision of means whereby the length of a line of matrices ma be simultaneousl determined and establis ed at the assemb ing, transfer and castin positions by a single effort on the part 0 the operator.

A further object is to provide means for indicating on the assembler scale the length of the line established at each and all of said positions, the index on said scale being automatically moved as the line is determined.

A further object is to rovide means for effecting a quick change inthe length of a line simultaneously at all of said positions.

A further object is to simplify the manner of connecting said elements in such a manner that old parts of the machine may not be rendered inaccessible, obscured or inoperable by the attachment of my improved mechanism, and additionally, to interconnect said elements across the front of the machine in order that a proper adjustment of the relationship therebetween may be effected by the operator without a loss of time.

A further object is to provide means whereby the assembling elements of the machine may be temporaril disconnected and disassociated from the other elements of my mechanism in order that an overset line of matrices may be adjusted and rectified by loosening the matrices therein without a fectin the line in said other elements.

A urther object is to provide an improved means at the. casting position for casting blank slugs of a esired length against the inner face of the movable casting jaw by locking said jaw in position during the castin operation, without affecting or moving t e other line determining elements.

Other objects may appear in the description.

Referring to the drawings, in which, and in the specifications hereinafter following,

similar characters of reference indicate the same parts throughout, Figure 1 is a plan of the forward portion of a well known form of line casting machine showing the relation of my improved mechanism thereto; Fig. 2 is a front elevation of the same; Fig. 3 is an elevation of the casting jaws and their inter-connections; Fig. 4 is a perspective view of the mechanism as assembled on a machine; Fig. 5 is a fragmentary sectional elevation of the movable castin jaw showing my improved jaw locking evice thereon; Fig. 6 is an end elevation of a portion of the vise frame and the pump stop mechanism; Fig. 7 is a perspective view of the line setting arm latch and a portion of the delivery slide clamp and rod; and Fig. 8 is a perspective view of a portion of the jaw setting rod and locking stud. Fig. 9 is a perspective view of the line stop and casting aw connection.

In the consideration of my improved mechanism, it should be understood that the same is applicable to any of the well known forms or types of line casting machines now in use, and with but a very little alteration of the old parts.

The right hand jaw 1 and the left hand jaw 2, as shown in Figs. 1, 2, 3 and 4 are slidably mounted on the jaw setting rod 3, but this rod 3 may be formed integral with or secured rigidly to the jaw 2, the movement of the left hand jaw 2 being limited to the left by means of a collar 4 secured to the rod 3 in any suitable manner. The rod 3 passes through the upwardly extending lugs 5 and 6 on the jaw 2 and the upper portion 7 of t he jaw 1, thence through the upper portion 8 of a block 9 in the direction and to a position in front of the assembling elevator 10. The end of the rod in front of the elevator 10 carries a line setting arm 11,

which is normally in the position shown in Fig. '4, the lower end of the arm extending down to a oint below the floor of the elevator, and t e u ,per portion of the armhaving a hub 12 w ich may be securedto the rod 3 in any suitable manner, and an upwardly extending lug 13 which is substantially opposite t e assembler slide 14, The lower portion of the arm 11 has also 0. lug 15 provided with a pin 16 which is adapte to engage a erforation 17 in an index 18 on the asseln ler scale 19, when thearm 11 is inverted, as hereinafter described.

I provide a suitable bracket which is secured to the forward side of the assembler slide 14 in a suitable manner, in the outer portion 21 ofwhich is threaded one end of a rod 22 which is held in place and locked to the slide 14 by means of a lock nut 23, the other end of the rod 22 being adapted to engage the vertical edge of the lug 13 on the arm 11 and thus limit the movement of the slide 14 to correspond with the other elements hereinafter described. The arm 11, may be moved slightly so that the lug 13 thereon may be disengaged from the end of the rod 22 without releasing the jaw 2. in the event of an overset line, in the assembling elevator for the purpose of removing the surplus matrices.

A vise'closing screw 24 is threaded into the block 9 at one end and extends outwardly therefrom for a convenient distance. This screw 24 is also revcrsely threaded into the right hand casting jaw 1, and its other end is threaded into the vise closing screw nut 25 and terminates in the vise closing bracket 26; the left hand casting jaw 2 being provided with a. semi-circular groove in the bottom adapted to engage the upper portion of the periphery of the screw 24 and to slide thereon.

A vertical rod 26 is secured to the upper edge of the jaw 2 and extends through the space between the inner and outer side of the line stop 27 with which the rod 26' is loosely connected by means of a pin or rivet 28 secured in both sides of the line stop and a flat upper portion 29 which is formed by extending and bending one of the sides of the line stop over the top edges so that the rod 26 will be held between the pin 28 and the inner edge of the upper portion 29, and a movement of the jaw 2 will also affect the movement of the line stop 27 therewith.

The jaw setting rod 3 has a plurality of peripheral grooves 30 which are equal in number to and correspond with the points on the assembler scale, and the block 9 carries a locking stud 31 having a removable head 32 on one end and a permanent head 33 on the other end, between the latter of which heads and the side of the vise cap 34, a spring 35 is interposed and adapted to compress. The rod 3 has a fiat portion 36 on its upper side in order to provide a clearance for the locking stud 31 when the rod is turned, the stud 31 being provided with longitudinal teeth 37 adapted to engage the grooves 30 in the rod 3, for preventing a movement. of the rod and looking it in a desired position. The stud 31 also has a cutout portion 38 at. the inner end of the teeth 37, so that in the event of a desire to move the jaw 2 without affecting any of the other associated elements, the movement thereof may be accomplished by pressing the head 33 of the stud 31 inwardly against the tension of the spring 35 until the cut-out portion 38 of the stud is beneath the rod 3 and the teeth in the stud thus disengaged from the grooves 30 in the rod 3, when the rod will be permitted to move over the stud.

The vise closing screw arm 39 is secured to the end of the vise closing screw 24 in the vise closing bracket 26, in the usual manner, and is connected with the vise closing screw connecting rod 40 carrying the vise closing spring 41, the other end of the arm 39 being provided with an extension 42 which is adapted to engage the upper end of a rod 43 mounted in :1 lug 44 on the vise closing bracket 26 and carrying a spring 45- adapted to compress between a washer 46 on the upper end of the rod 43 and the lug 44 on the bracket 26. as hereinafter described.

I provide the usual vise closing screw nut 25 with an extension 47 which extends under the jaw 2 a sufficient distance so that when the jaws 1 and 2 are in contact, a depression 48 in the inner end of the extension 47 will register with the lower end of a plunger 42) which is slidably mounted in the central floor portion .30 of the jaw 2, extends upwardly therethrough, and is provided with a. head 51 between which and the floor a spring 52 is interposed and adapted to hold the plunger normally upward. The central portion, or stem of the Plunger has an outwardly projecting pin 53 which extends through a slot 54 in the end of the jaw 2 and serves to guide and limit the movement of the plunger.

In lieu of the depression 48 in the extension 47 of the vise closing screw nut, I may provide a similar depression in the floor of the vise cap 34 to receive the lower end of the plunger 49, the purpose being to provide means for locking the jaw 2 in contact with the jaw 1 when it is desired to cast a blank slug against the face of the jaw 2. In such event, the jaws 1 and 2 are moved into contact, either with or without releasing the locking stud 31 from the rod 3, so that when the first elevator descends, the outer end of the elevator jaw 54' will strike the head 51 of the plunger 49 and force the stem of the plunger into the depression 48 in the extension 47 on the nut 25 and hold the plunger in such position until the slug has been cast, when the plunger will be automatically restored by the tension of the spring 52 and the jaw 2 released. 7

In order to adapt the delivery slide 55 to use with my improved mechanism, I provide a somewhat. altered form of delivery slide clamp 56, which is wider than the ordinary styles and has a bifurcated end 57 with a recess 58 between the furcations 59 and 60. The furcation 59 has a horizontal slot about centrally locatedbetween the top and bottom in which a dog 61 .is pivoted on a screw or pin 62, the inner portion 63 of the dog being curved from the front to the rear edge and extending into the recess 58 between the furcations 59 and 60, and the other end 64 of the dog being in the form of a pawl and adapted to engage and lock in the notches 65 in the horizontal rod 66 on which the clamp 56 and the long assembler finger 67 adjacent thereto, are mounted. The two ends of the rod 66 are secured, respectively, in a bracket 68 and an arm 69 attached to the delivery slide 55. The pawl end 64 of the dog 61 is held normally in engagement with one of the notches in the rod 66 by means of a spring 70 which is secured at one end to a pin 71 in the dog 61 and at the other end to a similar pin 7 2 on the delivery slide clamp 56, and when the line setting arm 11 is turned in an arc of 180 degrees, or a half circle around its axis, the end of the arm will engage the recess 58 between the furcations 59 and 69 and force the inner end 63 of the dog 61 inwardly so that the pawl end 64: thereof will be disengaged from the notch in the rod 66. the tension of the spring 70 serving to' hold. the end 63 of the dog 61 in resilient engagement with the end of the arm 11.

The lower end 73 of the ion assembler finger 67, as usual, engages the %lock 74 on the assembler slide 14, and the pin 16 in the lug 15 of the arm 11, as before stated, engages the perforation 17 in the index 18 on the slide 14, and the turning of the rod 3, having in the meantime released it from the locking stud 31, by pulling on the arm 11, the entire assembling, transfer and casting elements may be moved simultaneously thereby with a single effort on the part of the operator and the length of the line established and determined in each of the said elements thus made equal, the index 18 on the slide 14 serving to indicate the length of the line in ems.

\Vhen the length of the line has been determined and established. the arm 11 may be released from the recess 58 in the clamp 56 and restored to its lowered and normal position, which action locks the rod 3 on the locking stud 31 and maintains the assembler slide, delivery slide, the line stop and the casting jaws in their altered relationship until another change is made.

The pump stop mechanism used in connection with the above described line determining mechanism, as shown in the drawings, partakes somewhat of the general style of such devices in the more commonly used forms of machines, in some of the details, but it is necessary to change some of the parts to a limited extent in order that this mechanism may properly coo rate with the line setting mechanism for t 1e purposes set forth; it being understood that in other forms of machines the pump stop is operated by the right hand jaw 1, whereas in my device, the pump stop mechanism is controlled and actuated by the forward movement of the pot.

To the extended end of the vise closing screw 24, adjacent to the block 9, I secure a sector 75 by means of a set screw 77 in a hub 7 6, the sector having a peripheral notch 78, which, before a line is in readiness to be cast, is in a position normally to the rear of the vertical center line of the rod or screw 24, and an opening 79 being provided in the body of the sector which is sufficiently large to insure a free movement of the sector over the rod 3. The notch 78 is adapted to receive the outer end 80 of the pump stop lever 81, which lever in all respects except the end just described, is similar to the usual type of lever for this purpose and is pivoted on a screw 82 in the frame 83 of the machine. The inner end of the lever 81 has an upwardly extending pin 84 adapted to engage a notch 85 in one arm 86 of the bell crank lever 87 which is pivoted on a pin or screw 88 in the frame 83, the other arm 89 of the bell crank lever extending over the pot 90 and being adapted to engage the lower side of a lug 91 on the pump operating lever 92 when the pump is inoperative, as shown in Fig. 1. f

A lug 93 is provided on the pot stack 94, is parallel to the pot mouthpiece and has an adjusting screw 95 threaded in its outer end, the screw end thereof being adapted to engage a lug 96 on an arm 97 which is pivoted on the screw 82 above the pump stop lever 81. The arm 97 has a curved extension 98 adapted to contact and resiliently engage the edge of the pump stop lever 81, the resilient engagement being maintained by means of a spring 99 secured at one end to the arm 97 and at the other end to the lever 81. The adjusting screw 95 is normally out of engagement with the lug 96 on the arm 97 and only comes into contact therewith when the pot has moved forward against the mold disk.

When the pump is inoperative, the outer end of the lever 81 is in a position above the vise cap 34, as shown in Fig. 1, and adjacent to but not in contact with the sector 75, but when justification has taken place and the line is in readiness to be cast, the vise closing lever 100 having been actuated, the vise closing screw 24 will have been turned slightly forward so that the notch 78 in the sector 75 will register with the end 80 of the lever 81, this lever being actuated by the forward movement of the pot 90, and the end 80 of the lever will be caused to engage the notch 78 in the sector and thus permit the free movement of the pump sto lever 81 over the edge of the sector an the consequent disengagement of the lever arm 89 from the lug 91 on the pump operating lever 92, so that the pump may operate. The outer end 80 of the lever 81 is moved to the right by the arm 97 when the pot 90 moves forward, the screw end of the adjusting screw 95 contacting with the lug 96 on the arm 97 against the tension of the spring 99.

In well known types of machines, a slight movement is given to the right hand casting jaw 1 when the space bands are driven up during justification, whereas in in device, on account of the reverse threa s on the vise closin screw 24 in the jaw 1 and the block 9, t e driving up of the space bands does not move either jaw. The vise closing movement is divided between the right and left hand jaws, for as the vise closing screw 24 is turned slightly by the movement of the vise closing lever 100 and its connection with the vise closing screw arm 39 by means of the connecting rod 40 and the spring 41, the two jaws are caused to move toward each other a slight distance and the compensating movement is equally divided between the two jaws.

With a full line of matrices between the casting jaws, after the space bands have been driven upward, the extension 42 on the vise closing screw arm 39 will not press against the upper end of the rod 43 in the j.

lug 44 on the bracket 26 sufliciently to compress the spring 45; but in the event that a lose line of matrices is between the jaws, the spring 45 will be compressed thereby sufiiciently to permit the turning of the vise closing screw 24 until the notch 78 in the sector 75 has been moved out of registration with the end 80 of the lever 81, and thus prevent the movement of the lever 81 from operating sufliciently to release the pump lever 92 when the pot 90 finally moves forward, and preventin a cast of the line.

With the above descrfiied arrangement of the pump stop levers and associated elements, as the pot 90 actuates the pump stop lever 81 when it moves forward to casting position, if there should be an accumulation of metal between the pot mouth and the mold, the forward motion of the pot will be stopped before the extreme of its movement has been reached, and this stopping of the pot will prevent the complete disengagement of the lever arm 89 from the l 91 on the pump lever 92 because the adjusting screw 95 will not contact with the lug 96 on the arm 97, and the consequent operation of the lever 81 will be prevented and no cast will occur.

The operation of the line length ad'usting means is as follows: The length 0 the line to be set being first determined, the elongated arm 11 on the end of the rod 3 is turned upwardly until the end thereof is in line with the opening in the block 56 on the rod 66 and the pivotal movement of the arm 11 turns the rod 3 in the jaws 1 and 2' so that the flattened portions of this rod will permit the movement of the rod 3 longitudinally over the pin 31 in the block 9. The rod 3 together with the arm 11 may then be moved longitudinally, the end of the arm 11 first having been inserted in the block 56 for releasing the finger 67 so that it may be moved longitudinall of the rod 66. he finger 67 is released y means of the clamp block 56 which is capable of being normally locked to the rod 66 and the insertion of the arm 11 into the opening in the clamp serves to automatically release the dog 61 .from the rod 66. Thus the finger 67 the assembler index 18 which is adapted to be engaged by the pin 16 on the arm 11 when the arm is raised, and the movable casting jaw 2, are moved simultaneously with and by means of the setting rod 3 and the arm 11 thereon and the length of the line in all of these elements is established. The arm 11 may then be lowered, with all of the line length elements set, so that the extension 13 of the arm will rest in the path of the assembler slide rod 22 and serve to limit the movement of the slide 14 when the line of matrices is completed to the desired length. In the event that a line should be overset the arm 11 may be slightly raised so as to disengage the extension 13 on the arm 11 from the rod 22 and an additional movement of the assembler slide may thus be effected to accommodate the additional length of the line, after which the surplus matrices may be removed from the assembler.

It is conceived to be within the spirit and intent of my inventon to somewhat alter the form of the parts thereof and the arrangement of the coiiperating elements to a certain extent without enlarging the scope.

Having thus described my invention, what I claim as new and desire Letters Patent for, is:
