Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed September 80, 1915. Serial No. 58,879.

To all whom it may concern Be it known that we, Jo'HN SELLERS BAN- CROFT and MAURITZ C. INDAHL, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Shearing Mechanism for Lead and Rule Strip Casting Machines; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompan ing drawings, forming part of this speci cation.

The present invention relates to apparatus for producing printers leads, rules, borders, or printing elements of similar character, and more especially to mechanism adapted to produce the printingvelements by an 111- termittent action, but in indeterminate lengths, the object of the invention being to provide a means whereby the strip may be severed into lengths which may be accurately predetermined, thus adapting the machine for delivering printers leads or rules, for example, of any desired length within the capacity of the machine, and eliminating the necessity of hand shearing, such as has heretofore been necessary to make the leads and rules fit the forms or make-up for printmg.

The invention, while not limited thereto, is primarily adapted for use in connection with Lanston monoty e casting machines, such, for example, as t at set forth and described in Letters Patent No. 625,998, granted to J. S. Bancroft, May 30. 1899, as modified and adapted for the casting of leads, rules, etc., by intermittent operations of casting and feeding, the machines so modified being now in commercial use and the novel features are set forth in a contemporaneous application for patent, filed in the name of Amos L. Knight, on October 3, 1914, Serial No. 864,894.

The invention consists primarily in combining with an intermittently acting lead and rule casting machine for producing a stri of indeterminate length, a shearing mec anism actuated through power connections with the driving mechanism of the casting machine, but controlled by the strip produced thereby in such wise that theshearing mechanism for severing the strip op crates when the strip is at rest, thus insuring the cutter operating ing accuracy in the length delivered with means whereby such length may be varied at will for the roduction of leads or rules of any desired ength, or to fit the work in hand.

The invention further consists in a shearng mechanism in which the cutting device s moved in unison with the strip by a age interposed in the path of the strip an the cutting operation performed at any oint in the length of the strip as determined by the d stance between the gage and cutting de vice.

The invention further consists in certain novel details of construction and combinations and arrangements of parts, all as will be hereinafter described and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a front elevation of a portion of a Lanston monotype casting machine, many of the parts having no s ecial relation to the present invention being omitted, and parts relating to the present invention added. Fig. 1' is a view corresponding to Fig. 1 and showing those portions of the machine to the right of the portions shown in Fig. 1, the two views Figs. 1 and 1" being intended to illustrate in front elevation the machine embodying the present improvements, omitting only the fixed table on which theleads and rules are delivered from the shearing mechanism. Fig. 2 is a sectional elevation looking toward the left in Fig. 1 and showing the lead and rule guide, the operating mechanism therefor, the lead and rule support, and the movable table, the fixed table being shown in dotted lines. Fig. 3 is a view corresponding to Fig. 2, but omitting the guides and their support and showing, in addition, the cutter 0 rating and lead transferring mechanism. ig. 4 is a front elevation showin on an enlarged scale portions of the. mec anism shown in Fig. 1. Fig. 5 is a perspective view showlever and lever which is carried thereby for operating the guide. Fig. 6 is a perspective view showing the cutter carriage, cutter and adjustable gages for regulating the length of lead or rule to be delivered. Fig. 7 is a sectional plan thron h a portion of the mechanism shown in ig. 6, together with the guide roller for supporting the lead or rule strip at the point where it enters the cutter carriage. Fig. 8 is a detail plan view of the adjustable gage mechanism shown in Fig. 6. Fig. 9 is a Sectional elevation substantially in a plane indicated by the line 99 in Fig. 1 t e spring at the left hand end being shown in dotted lines. tive view of a art of the bell crank lever for operating t e cutter. Fig. 11 is a perspectlve view of the trip mechanism for releasing the inte onent to effect the operative connection etween the operating or power lever and the bell crank lever.

Like reference characters in the several figures indicate the same parts.

The mechanism illustrated as the preferred embodiment of the present invention is designed for use in connection with a Lanston monotype casting machine and in order that the relationship of the parts may be properly understood from the accompanying drawings, there are shown in Figs. 1 and 1' in a conventional manner, certain parts of the monotype machine which Wlll be at once recognized by those .skilled in the art. The mam frame of the machine is indicated by the reference numeral 1; the cam shafts by the numeral 3; the drive shaft by 4; the lever operated by cams on the cam shaft for reciprocating the mold blade, by 5; the bracket which carries the galley by 6; the vertically adjustable melting pot and its supporting bracket by 7 and 8, respectively; and the nozzle through which the molten metal is injected into the mold cavity by the dotted lines at 9.

In the production of printers leads or rules in the form of a strip of indeterminatelength, the molten metal is injected into the mold cavity between the end of the mold blade and the congealed ortion of the metal previously injected. his portion of the apparatus, in so far as the specific construction is concerned, is the invention of Amos L. Knight and is embodied in the before-mentioned application. In the present illustration the more or less diagrammatic showing is thought to be sufficient to illustrate the operation of forming and feeding the strip. By reference to Figs. 1 and 1" it will be seen that the lead or rule indicated at 10 has been formed by the injection of metal fed forward intermittently by the reciprocation of the mold blade 11 through the medium of the operating lever 5 and connections 12 intermediate said lever and mold blade, a portion of which connections are shown broken away. Metal havin been injected through the nozzle 9, congea s, and by the next forward movement of the mold blade 11, it is advanced into a position which will permit of the formation of a cavity for the next increment of metal when the mold blade is withdrawn. Each incre- Fig. 10 is a perspecthrough the nozzle 9 and ment of metal, fuses with the metal previousl injected, thus uniting the lead or rule in the form of a long strip which is intermittently advanced and is guided to the cutting mechanism where it is subdivided into sections of the desired length.

Through mechanism which will be presently described the cutting mechanism is preferably operated in such wise that, when the actual severance is effected, the lead or rule is stationa and the power for operating the cutter is preferably derived from one of the cam shafts 3. Said cam shaft is provided with cam 13 upon which rides an anti-friction roller in the shorter arm of an operating lever 14, pivotally mounted in a bracket at the front of the main frame or stand 1, and with its free end projecting a short distance beyond the meltin pot 7.

The cutting or shearing mechanism, except for the parts hereinbefore described is all adapted to be mounted upon or carried by the bracket which supports the melting pot, and is movable in unison therewith into and out of its operative position, and to adapt it for application to the standard monotype machine, it preferably embodies a vertical bracket or frame 15 which is adapted to be secured to the melting ot bracket by bolts 16 or other appropriate astening means, and at its upper end to support a rigid horizontal bar or extension 17. The entire shearing mechanism per 86 is mounted on the bracket frame 15 and its extension 17; thus the entire mechanism may be readil applied or removed.

Extending own from the part 17 are two supporting arms 18, the lower ends of which carry a horizontal track or way 19 upon which the lower edge of the lead or rule strip ma travel. intermediate the mold and the way 19, by a guide roller 20, best seen in Fig. 7 and adapted to be adjusted by a movement of its eccentric support through the. medium of a handle 20 at the front of the frame 15. The shearing or cutting devices are mounted to move parallel with the strip intermediate the guide 20 and the way 19, and said shearing or cutting devices preferably embody a carriage or frame 21 having top and bottom guide surfaces 22 to cooperate with corresponding surfaces formed in the rojections 23 of the bracket frame 15. he carriage 21 may conveniently be called a sliding cutter frame, and mounted within it in suitable bearings is a transversely movable knife or cutter 24, said cutter being adapted to intersect the end of the opening 25 through which the strip passes and by the cooperation of the movable cutter'24 and one wall of the opening 25, which is in effect a fixed cutter, the severance of the strip is effected. I}

In order to locate the cutter with respect 10s The strip is supported to the end of the strip, whereby the accuracy of the length of strip severed may insured, the sliding cutter frame is provided with a long and preferably square gage rod 26 conveniently guided at its outer end in a guide formed on the extremity of the way 19 and upon this gage rod there is mounted an adjustable gage, with which the end of the lead or rule strip is ada ted to contact and whereby the cutting evices will be moved in unison with the strip, for a limited distance. The gage preferably employed embodies a clamp collar 27 .adapted to be set in any desired position of adjustment in the length of the rod 26, and a slide 28 having collars 29 embracing the rod 26 with i an interposed spring 30 for holding the slide 28 advanced. The slide 28 carries a ge or bracket in position for the end of t e lead to contact therewith, and in this preferred construction it carries two of such gages or projections,that indicated at 31 being;

he turned pivotally mounted so that it ma from the position indicated in ull lines to that indicated in dotted lines in Fig. 8, while that at the opposite or outer end of the slide is a rigid gage or projection 32. The pivoted gage or bracket 31 is held in its adjusted position by a retaining collar 33 held advanced by the spring in position for its lateral projections 34 to bear yieldingly against one or the other of the flat surfaces of the gage, thus forming a type of well known retaining devices conveniently adapted for the particular situation where now employed. Obviously, by the use of one or the other of the

projections

31, 32, the range of lengths into which the strip may be cut is considerably increased.

All of the movable parts of the shearing and cutting mechanism which are moved by and in unison with the lead or rule strip must be made as light as ossible, inasmuch as it is frequently desira le to cut exceedingly thin strips, the strength of which would be insufficient to move the cutter if of heavy construction, or, if suiiicient to move these parts, the strip itself would be deformed, either at the end or by buckling at an intermediate point. For the reasons stated and others, it is desirable that the cutters be afforded the greatest freedom of movement in unison with the strip, and this has necessitated the provision of means whereby the transversely movable knife may be connected with its operating mechanism without imposing a load on the strip itself. In the preferred construction, a forked operating lever 35 is provided, said lever being ivoted at its upper end on the frame 15 an provided at an intermediate point with a horizontal shaft or pin 36, passing through an eye or bearing 37, Figs. 6 and 7, in the rear end of the knife or cutter 24. The length of the pin 36 between the arms of the lever 35 is suflicient to permit of a full movement of the cutter frame in unison with the strip and a slight overthrow, should the momentum of the parts carry the cutter frame awayfrom the end of the strip. The lower end of the forked lever 35 is normally held in position with the knife or cutter 24 retracted, by a spring 38 and movement is imparted to it for advancing the cutter 24 by a bell crank operating lever 39 having a cam face or wiping surface 40 cooperating with the lower end of the lever 35, the normal position of the two levers being determined by an adjustable stop 41. Movement is imparted to the lever 39by the long operating lever 14 hereinbefore referred to and the connection between the 0 rating lever 14 and bell crank operating ever 39 is effected by an interponent 42 under the control of the lead or rule strip through the movement imparted by the latter to the gage and sliding cutter frame or carriage. The mechanism for effecting such control embodies a releasing and resettin latch mechanism for the interponent and a ever operated by the sliding cutter frame for operating the latch mechanism, such parts being best seen in Figs. 1", 3, 4, 10 and 11. By reference to Fig. 4 it will be seen that a light lever 43 is pivotally mounted on the bracket frame 15 at a point intermediate the length of the lever, the upper end of said lever being in position to be moved by the sliding cutter frame 21 whenever the gage is advanced by the lead or rule strip.a The lower end of the lever 43 projects tween the proximate faces of a pair of

escapement pawls

44 and 45, normally held toward each other by an interposed spring 46 and both, together with the lever 43, normally held with the upper end of the lever against the cutter frame 21 by a spring 47, the outer end of which is secured to a downwardly extending'fixed arm 48. The lower ends of the escapement pawls 44 and are provided with shoulders 44' and 45, adapted to serve as stop shoulders for the upper end of a bolt 49, the lower end of which bolt is pivotally connected with a bell crank lever 50, mounted on a pin carried by the latch operating bell crank 39. The other arm of the small bell crank lever 50 is adaptedto contact with a pin or rod 51, extending through a suitable guide 52 and jointed to the interponent 42, see Figs. 3 and 10. A spring 53 holds the 'bolt, interponent and bell crank lever 50 toward each other, and a spring 54 connected at its upper end with the frame or bracket 15 normally tends to elevate the bolt 49 and to advance the interponent 42 from the position shown in full lines to the position shown in dotted lines in Fig. 3. The upward movement of the bolt 49 is, however, normally prevented b the escapement pawl 45, against the shou of which the bolt seats, as shown in spring 47 to swing the escapement pawl 45 away from the end of the bolt 49, with the result that the bolt 49 moves upwardly and the interponent 42 swings out under the operating lever 14. Upon the descent of the operating lever 14, the bell crank lever 39 will bedepressed at its outer end, the lever 35 will be swung inwardly, and the knife or cutter 24 advanced to sever the strip. The downward movement of the outer end of the bell crank lever 39 draws the bolt 49 downward and the moment the upper end of the bolt passes the shoulder 44 on the escapement pawl '44, the latter swings inwardly under the influence of the s ring 46. U on the return movement of tiie operating ever 14 taking place, the bolt is held down and the interponent swung back from the dotted line to the full line position, or to approximately the full line position, for the shoulder 44" is a very slight distance below the shoulder 45 and the end of the bolt is transferred from one shoulder to the other, by the return of the sliding cutter frame and lever 43 to normal position under the influence of the spring 47.

From the foregoing it will be seen that the only load imposed upon the lead or rule strip in order to set the cutting mechanism in position to be operated from the power connection, is the inertia of the sliding outter frame, the lever 43 and escapement pawl 45 with the tension of the sprlng 47. All of the arts referred to may be made exceedingij light and the tension of the spring adjusted so that it will yield under a very slight ressure, but at the same time the tension of the spring should be sufficient to insure the return of the sliding cutter frame and parts carried thereby to normal position, ready for a subsequent operation and to hold the age in proper engagement with the end of t e strip.

The lead and rule strip after passing through the sliding cutter frame travels along on the guideway 19 and between sup-.

porting ides and 55", see Figs. 1", 2 and 9. hese supportin guidesare 1n the form of bars arranged a ove the ldeway 19 and carried on the lower ends 0

hangers

56 and 56 depending from a horizontal shaft 57 supported b the arms 18 and forming a journal for t e said hangers. The hangers are held toward each other with the supporting guides in proper normal relation by an inter osed tension s ring 58 and both hangers an guides are he d in position over the guideway 19'by spring 59, but are capable of being swung either together or there be any tendency for the different distances toward the front of the machine, for example, shown in full lines to that shown in dotted lines in Fig. 2. When so moved, the strip held between the guides55 and 55 will be moved transversely off of the guideway 19 and permitted to drop on to the swinging section 60 of the supporting table, as will be hereinafter described. For operating the supporting guides and insuring the proper support of the strip while it is being fed forward and adjusting the cutting mechanism and also for insuring, the release of said strip when the supporting guides are swung oil to one side by opening the guides and releasing the strip, should same to stick, an operating lever 61 is pivotally mounted on the end of the bolt or in 36 which advances the laterallyv mova le knife or cutter, and this lever 61 is provided with three arms, the lower arm 61" being adapted to contact with a rocker 62 to be presently described, while the intermediate arm 61 is adapted to contact with the supporting guide 55", and the upper arm 61 to contact with the hanger 56 of the guiding support 55. The relation of the as the forked lever 35 swin s inwardly, the movable knife or cutter is rst advanced to sever the strip, whereupon the lower arm 61 of the lever 61 strikes the rocker 62, whereby its forward movement is arrested and the upper arms of said lever come into contact with the guiding support 55 and hanger 56 to move said guiding supports laterall The guiding support 55 is moved a conslderably greater distance than the guiding support 55, whereb the two are .Separated so as to permit 0 the free discharge of the severed section of the stri To insure the discharge of the strip should there be any tendency of the same to stick against the face of the guiding support 55, a series of fingers 63 are secured to the guiding support 55 and extend over and around the guiding support 55. They pass through notches or openings 55 to a point beyond the face of the support when the parts are swung to their extreme left hand osition (see Fig. 2), The position of the ever 61 with relation to the operating lever 35 and consequently the normal position of the guiding supports may be determined by an adjustable stop in the upper end of the lever 35, such stop conveniently taking the form of a set screw 64.

The severed section of the lead or rule strip drops down upon a pivoted or swinging section 60 of the receiving table or ga ley, and in order to stack the successive sections and move them out of the path' of sue ceeding sections, a rocker 62 is pivotally mounted in bearings in the frame 15 and arm 18, respectively, said rocker being profrom the position parts is such that, r

vided with a series of projections 62', which, when the, rocker is operated, will oscillate back and forth to the full and dotted line positions shown in Fig. 2. When turned to the full line position, the projections 62 will push the sections of lead or rule strip forwardly, as indicated in Fig. 9, and when turned back to the dotted line position a space is left for the reception of a succeeding section of strip, one of which latter is shown in dotted lines as descending to the table in Fig. 2, at 65. For operating the rocker 62, it is conveniently provided with a rearwardly projecting arm 66, Fig. 3, connected by a link 67 with the bell crank operating lever 39 atr a point forward of the axis of the lever. The link 67 may, if desired, be a yielding link, or embody in its construction a well known form of spring box 68. The downward movement of the forward end of the operating bell crank lever 39 serves to turn the rocker rearwardly to withdraw the projection 62 from the path of the descending section of strip, and

the upward movement of the bell crank lever 39 returns the parts to their normal position and pushes the stack of leads or rules forwardly over the table 60. The pivoted section of the table is hung on the rocker 62 and is provided with a forwardly extended pro ection 60 adapted to cooperate with the edge of the fixed section 60 of the table, and a spring 69 'is provided for turning the pivoted section 60 up out of the way when the melting pot is lowered for the purpose of inspection or for other reason during the adjustment of the machine. The pivoted section 60 of the table or galley thus moves with the shearing or cutting mechanism, while a fixed section 60 remains in position in front of the said mechanism, just as does the galley or table of the ordinary Monotype casting machine.

The operation of the apparatus will be readily appreciated from the foregoing de- SCIl tion. The operator having determined the ength of the sections of the lead or rule I strip he desires, sets the adjustable collar 27 on the rod 26 at the proper point to give the desired distance between the gage or projection 31 and the fixed cutter or cooperat- 111g edges of the fixed and movable cutters, and should the. length of stripl desired be greater than can be secured by t e use of the gage 31, the latter is turned out of the wa and the gage 32 employed. The strip is a vanced intermittent y owing to the fact that it is cast in sections, and each section ad-' vanced before the next section is cast.

The operating mechanism for the operating lever 14 as well as the 0 rating mechanism for the lever 5 whic advances the mold blade all derive motion from the same drive shaft, with the result that by properly positioning the cams, the two levers are caused to move in a pro 1' sequence, the lever 14 moving downward y at its outer end while the mold blade is being retracted or is at rest, and owing to this relationship it is ossible to effect the severance when the strip is stationary. Assuming that the strip has advanced with a jump, causing an overthrow of the sliding cutter frame, the latter will settle back to its correct position for making the out before the operating lever will move the parts to effect the cut. With the arrangement described it has been found possible to cut the strip into sections which are within the permissible variation from absolute standard in printers make-up work, and inasmuch as the machine is entirely automatic in its action, it ma be set to cast and cut definite lengths an when once set in operation, requires little or no further attention.
