Application filed. December 1, 1904, Serial .No. 235,126

To all whom it may concern:

-Be it known that we, JoiiN SELLERS BAN- CROFT and MAr-Rirz (l. INDAnL, both 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 T ype-Machines; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to improvements in or upon what is known as the monotype type casting machine, and it has for its principal object to enlarge its capacity in such degree that it may be utilized either as a composing machine e. for the production of type in the order of composition and the assembling of the the production of head-line or display type of a size' greatly in excess of the present capacity of the machine.

To this end the invention consists in supplying certain additions to the pump action, centering mechanism, type carrier and mold blade operatingdevices, and substitutes for the type carrying and delivering devices, the latter parts being interchangeable with cor responding elements of the composing machine,all.as hereinafter fully described, the novel features being pointed out in the claims.

In the accompanying drawings illustrating a, preferred form of embodiment, Figurel is a diagrammatic top view of the casting machine, as provided with the additions for converting it into a-sorts caster. Fig. 2 is a peractuating mechanism embracing the additions thereto. Figs. 3 and 4 are partial side showing the trip action in two positions. Fig. 5 is a perspective view of the trip.

ing attachment. Figs. 21 and 22 are side ing connections showing -t e parts in two positions of adjustment.

Similar numerals designate like parts in the several figures.

The type casting and composing machine illustrated is in all essential particulars similar to that of Patent 625,998 plus the improvements of Patents 674,374; 674,375; 674,376; 700,290 and 752,814 to which reference may be had for the details of construction and modeof operation.

It will suffice for present purposes to designate some of the principal groups, of mechanism, such as the die-case system 1 including die-case frame, carrier and centering .lunger the mold 2,with its movable mold b ade and cross-block; the diecase centering inechaiiism 3, with its two sets of centering devices operating in transverseplanes and controlled by stop pins; the paper feed 4 for the perforated controller; the metal injecting mecli anism 5; and the galley mechanism 6.

The foregoing are constituent parts of the commercial casting and composing machine, but when the latter is equipped as a sorts caster the shifting of the die-case, the auto matic adjustment of the nlOltl-blitQlG and the assembling action of the galley mechanism are not required, hence these motions are sus pended by locking the paper feeding devices so as to maintain the record strip in position, and disconnecting the normal wedge from the centering mechanism so that it may be set or adjusted independently, to gage the mold irrespective of the position of the die case.

. The-type which the sorts caster is designed to produce greatly exceeds in lateral (iifli'itil'l Fig. 20 'is'a detail partly in section of said multiplysions the maximum capacity of the machine when used for com osltion, hence a mold 2 (Figs. 8 and 1.1) of arge capacity, but of the same general character is substituted for that of the composing machine (see Patent 752,814); the normal wedge 7 (Fig. 10) which controls the position of the mold blade 8 for dimensioning the body to correspond with the character is deprived of the projection for engaging the jaws of the centering mechanism, and, in lieu thereof, is provided with a rod or extension- 9, (Fig. 10) to facilitate manual adjustment; and the series of matrix blocks are removed from the die-case and relaced therein or in a substitute therefor by a liolder or block 10 (Figs. 14, 15 and 16) equipped with a centering cavity for the centering and holding lunger 11 and with means for detacha'b y securing a 'matrix block or plate 12 to its lower surface facing the mold cavity. The matrix block 12 contains an impression of the character to be produced, justified with relation to two of its sides or edges, and the h0lder 10 is provided with shoulders 13, 14 at right ang1es,'toreceive said edges and serve as gages for positioning the matrix in proper relation to the centering plunger. Angular clamping blocks 15, 16 seated on the holder 10 and provided with diagonal adjusting screws 17, engage the edges of the matrix block opposite the gaging shoulders 13, 14 one of said. blocks being provided with a li overlapping the edge of the matrix block t e opposite edge being in like manner engaged by an adjustable clamp 18, to retain said matrix block firmly in its seat on the holder. The centering cavity for plunger 11 is contained in a bearing 19 removably inserted inthe upper face of holder 10 with the axis of its conical seat in such relation to gages 13, 14, that when said plunger is depressed, to finally center and clamp the matrix upon the open end of the mold, the character impression will be justified with relation to the side walls of said cavity. The capacity of the mold so far exceeds thatused ordinarily for composition that the range of motion permitted the mold blade actuating devices 18 insutlicient to compass the two extreme positions assigned the'mold blade for maximum set ways dimension and for ejecting the-type and delivering it to the carrier,

hence an addition is made to said actuating devices, whereby, by a simple adjustment or readjustment of parts, the motion derived from the mold-blade actuating lever can be increased, to conform to the requirements of the sorts caster or reduced to normal conditions incident to its use as a composer. Such an arrangementis shown in Figs. 19 and 20 wherein the actuating lever 26 (178 of Patent 625,998) for effectin the reciprocation of the mold-blade is provi ed with a short lever 27, one arm whereof engages the mold-blade con nection' 28, while the other is in position to be ssasre connected pivotally to a fixed bearing 29 on the frame, as by having its furcated end confined between a removable washer 30 engaging bearing 29 and the head of a screw 31 threaded into said bearin so that as lever 26 is vibrated its motion wi l betransmitted to the mold-blade through lever 27, which latter, being of the third order, Will increase the motion at its weight end. This is the con dition established when the machine is equipped with a large mold and used as-a sorts caster; and in order that normal conditions may be reestablished it is only necessary to rigidly connect the supplemental or multi lying lever 27 to the actuating lever 26, wli drawal of screw 31 from the fixed bearing,

ich can be accomplished by'the withthe insertion of the washer 30 between'lever 4 cident to carelessness in misplacing detached elements. is avoided.

The use of the larger mold of course necessitates the employment of a type carrier of larger capacity and it is proposed to equip the composing machines with a type carrier adapted to handle all sizes, the principal requirement being that the opening for the reception of the type be enlarged and the throw of the movable jaw and the type support correspondingly increased. Otherwise the type carrier does notdiifer essentially from those of Patents 625,998 and 674,375, except that the lever 20 for operating the type support is arranged on a horizontal instead of a vertical pivot, and is adapted to engage a removable stop or abutment 21. on the frame, and the stroke of the type carrier is slightly increased to compensate for the enlarged capacity of the mold. which re uires that the type opening in the carrier s ould alternately register with'the mold cavity and the entrance to the discharge passage.

As a simple and ready means for eflecting the adjustment of the throw of the type carrier and its position for use either as a composer or a sorts caster, its actuatinglever 80 is equipped with a stud 81 providedwith two pivot bearings 82, 83, the one slightly above and to one side of the other, as shown in Figs. 21 and 22, and the connecting rod 84 for the type carrier is furnished with a head 85pmvided with two pivot bearings 86, 87.

The normal connection for the composing machine is made by inserting the pivot pin 88 in bearings'82, 87. see Fig. 22; and when it is desired to use it as a sorts caster, the in is' withdrawn and the carrier shifted to ring bearings 83 and 86 into alinement, and the tering seams in is inserted therein as shown in Fig. '21.,-

he blocks at the entrance of the line channel forming part of the galle Y mechanism are also removed and two ,bloclis 22, 23 (Figs. 11 and 12) forming a curved guide way opening upon the galley and fitted to the bearings for the removed blocks are substituted for the latter. Theblocks 22, 23 are detachablysecured to the-seats of the line channel hlocks bi} means of screws 75, the openings for w 'ch register with the threaded openings which receive the corresponding screws of the regularline channel blocks. OnePor both i of said blocks 22, 23, is or are equipped with a spring retainer 24 for preventing the return or displacement of the type after it has been thrust from the holder y the ejector 25.

The equipment thus far described would action of these parts and which do not inter few with the normal 0 ration of the machine as a composer. 'l d increase the pressure'on the matrix, when in closed position upon the mold, an auxiliary compression device or member is detachably ap lied intermediate the centering plunger and its actuating lever, to reinforce the action of the normal compression spring 42.

In the preferred form illustrated in Fig. 8

. the auxiliary compression device consists of two plates 34 each provided with a side opening 35 and a seat 36 for receiving either the head 37 against which actuating lever 38 bears, or a collar 39 on the centering plunger 11. 'Springs40, one or more, are interposed between said plates 34, and. the latter are connected by bolts 41 secured to one plate and extending through the springs and guides on the opposite plate, beyond which latter they are provided with nuts 42 When used as a sorts caster the auxiliary compression device is slipped into place between head nterfering with 37 and collar 39, so that when the centering plunger is seated the further motion of head 37 will compress the springs and thus add theintension to that of the normal compression spring inf holding the matrix to its seat on the mold.

, To render'the ump mechanism effective,

the stroke of the piston be it-is required that increased and at the same time be rendered more powerful, to accomplish which, without the of the machine,

anauxil'iary pump controller is applied in connectionwith f"'the piston actuating devices, operating to'lock or-retard the-moves ment of the. piston during the initial motion of the actuator or-driving member, and at a oint-be ondthecorn ressions ,"so that the latteiwill becomdiessed/or iii ic ed under tension, the energy thusstor beingsuddenly a plied to the. piston by the withdrawal of the ocking or retard' devicesg A-prefer-red embodiment of thisaux'iliarypump controller ada ted specially foruse'inconmotion with t 'e pum mechanism of Patent 674,374, is illustrate in 2 to 7' inclusive. L i

It will suffice for present purposes to designate those elements of the prior structure with which the im 'rovements are immediately connected, re erence' bei had to the patent for a more detailed description there of. These elements are. the , l'evers 43, 44 connected by link 45, one of said levers engaging the pum' frame 46 and the other-the piston rod 47; t e head 48 secured to vertically movable rod 49 and connected to the power end of pump-framelever 44; the head 50 provided with an ofl-set 51 engaging compression spring 52, the latter in turn engaging'rod 53 attached to piston lever 43; and actuating rod 54 carrying head, 50 and-an arm 55, the latter engaging-a spring. 56 bear- "ng against a collar on rod 49.

to elevate heads 48 and 50 and with them the pump and'power ends of levers 43, 44 until, a y theengagement of a stop 57 on rod 49, the head 48 and pump frame lever 44 are arrested, whereupon rod 54continuing to rise,

head 50 is separated from head 48 and its motion transmitted to the piston lever-43 through the. compression spring 5 2. This is the normal action of the pump mechanism,

and it is evident that the motions of rod 54- being uniform, as derived from. the actuating mechanism, the throw of the piston can be varied by the adjustment of stop 57. Such adjustment is-permissible but as it ail'ects not only the seating of the nozzle and the time at which the amp begins towork, it is "employed principa ly in connection with the initial adjusting and timing of the machine as a whole. In the present instance, however, advantage is talren or this feature for increasing the throw of the piston without interfering with the timing, other revisions being made therefor, as 'Wlll present y appear, and this is accomplished by interposing a distance piece or gage 58 between the stop 57 and an abutment, such as the frame. In the exam le given the distance piece is )lVOlZ- ally attac ed to the frame and adapter to be 'swun into or outof engagement with said stop, lieing held in either position bya spring 59 attached to'the frame so as to swing-on op osite sides of the, pivot.

o the head 48"is secured a rod 60 upon which is mounted a vertically movable sleeve -.61 provided with anofi-set or arm 62riding he pump actuating'mechanism operates upon rod 54:

, upon rod 53 and occu retracting spring 63 and Wit a shoulder 64,

preferably in the form of 'a hardened steel 1nsert,'in position to engage the lower'orvertical arm of a latch 65, the latter pivotally attached to a collar 66 adjustably secured to the upper-end of rod 60. J,

The plvot of latch 65 is located above and j in line with shoulder 64, and when the sleeve 61 occupies its normal or retracted I osition the engaging arm of said latchstan s above and in line with the upper face of'said shoulder, being held in this position by a spring 67. This spring instead of acting, directly upon the latch, as it might if the attachment was constantly in'use, acts indirectly through a lever-68 supported u on the pivot pin of the l'atch and provide -with an off-set 69 adapted to engage. either of two se arated bearings on the latch. The spring 67 as one end attached to one arm of lever 68, the opposite end being attached'to collar 66 in such position that when the lever engages one of the hearings on latch 65 it will draw the. arm

of the latch 65 towards shoulder 64, on

sleeve 61 (see Figs. 3 and 5') and when turned to engage the opposite bearing 70 it will swing across the pivot'and draw the latch away from and out of contact with shoulder 64, thus disconnecting thev tripping attachment. The latch 65 is also provided with a tripping member or arm 71 located in the path of and at a distance above a projection or shoulder 72 carried by head 51. a The interval between tripping arm 71 and shoul-' der 72 determines the amount of-travel permitted head 51 after head 48 has been are rested by gage 58 and the degree of compression applied to spring '52 before it is 'per mitted to act upon the piston lever 43, foruntil latch is engaged and moved out of contact with shoulder 64 the'separation of levers 43, 44 at their power ends is prevented, although'they are free to move in unison for effecting the elevation of the pump and the seating of thenozzle.

Assuming that the machine is equipped as asorts caster with lever 68 and gage 58- in operating position. and actuating rod 54 retracted so that heads .48 and 50 are in contact and resting against the supporting frame, the operat on of this feature of the invention will be as follows: As actuating rod 54 rises the two heads 48, 50 move in unison, until gage 58 arrests head 48 and with it the pur'n'pframe lever 44, to ether with piston lever 43, the latter being $01 the time-locked to'head 48 by the'engagement of latch 65 with sleeve 61. Head 50.is however free to continue its motion, and inso doing compresses spring;5-2 until, by the engagement of its shoulder 72 with the tripping arm 71,-

the latch is finally withdrawn from shoulder plates. I v
