To all whom it may (:0 "r cer'n Be itknown that I, FRANCIS H. RICHARDS,

a citizen of the United -States, residing at- Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful 'Improyements in Type-l3ar Machines, of which the following is a specification.

My present invention relates to mechanisms and to organizations thereof, each of the mechanisms being capable of performing a particular operation relating to the process offorming typebars from a continuous ribbon or strip of type-forniable material, while the organization of said mechanisms according to my present invention provides for the performance of such operations in a proper sequential order. Such an organization of mechanisms ordinarily includes members adapted to swa e or forge types upon the edge of such ri bon or strip, to triin'the continuous typebar so'formed and to divide thewsame into lengths to form typebarsybesides embracing various features of construction and combinations of parts allot which, individually and as organized in an operative machine specified as above, are described-in the following specification with the aid of the accompanying drawings.

I11 these drawings, Figure 1 is a front elevation of such a typebar-machine embodying my improvements, certain parts being broken away. Fig. 2 is a longitudinalvertical sect-ion thereof, the plane of this section being somewhat removed from that of the axis of the main driving-shaft of the machine as shown in Fig. 1, although this shaf t and certain parts, some of which are mounted thereon, are shown .4 full in this figure while certain other parts are omitled entirely, or broken away. Fig. 3 is a view of the machine as seen from the rear, certain i anismshowing the relation of said mechanparts being also broken away. Fig. 4 is a view looking at the underside of the machine,

. certain parts in this figure being likewise broken away. Fig. 5 is a plan view "of the machine upon a somewhat smaller scale than that to which the preceding and succeeding i views are drawn. Fig. -6 is likewise a plan view, certain parts being omitted, while certain other parts are shown in section. Fig. 7 is a view similar to Fig. 6, with the diehead and certain portions of thedie-adjnsting mechanism, shown in the latter figure, omitted. Fig. 8 is an elevational "iew of .bers.

the machine as seen from one end, certain parts being broken awa Fig. 9 is an elevational'view of the mac info as seen from the opposite end. Figfi10 is a transverse vertie .cal section on the plane of the broken line 1010 in Fig. 6, looking in the direction of the arrow adjacent to that line, certain of the parts being broken away, while certain other arts are wholly omitted. Fig. 11 is a simiar transverse section upon the plane, however, of the line 11-11 in Fig. 1, looking in the direction of the arrow adjacent to that line, certain portions being shown in elevation, while cert-am other portions are broken away. Figs. 12, 13, 14 and 15 are plan views representing various positions assumed by certain indicator mechanism designed for the purpose of indicating to the operator when an amount of feed movement of the strip has taken place nearly sufiicient to form a typebar length. Fig. 16 is a sectional elevation illustrating certain feed mechanism for 'efi'eoting a step-hy-stepv or intermittent motion of the contimious typebar-blank. Fig. 17 is a perspective view representing a carrier for moving the work-holder for the strip or ribbon toward and away from the dies during the l'orn'iation of successive types and spaces. Fig. 18 is a perspective View 01' such work-holder with one of its guide niem- Fig. 19 is a similar view of one of such members. Fig. 20 is also a perspective view showing a support for the journal portion of one of such members. Fig. 21 a perspective view of a cutting instrument for removing surplus material 'l'romthe continuous strip after such material has heeniorced beyond the planes of the sides of the strip as the result of operating upon the latter to form types upon its edge. Fig. 22 is an elevational section of certain indicator mechism to the str p or ribbon. Fig. 23 is apers icctive view of a portion of the mechanism shown in Fig. 22 and a portion of the strip orrihhon with which it engages. Fig. 24 is an elevation of a lockingdate and shows the relation of certain dieare and the die-bar head thereto. Fig. 25 is a side view of such locking-plate and a port-ion of other partsindicated in Fig. 24. Fig. 26 is a'view similar to Fig. 25, but shows ccrtainparts in section, tln plane of which is the line 2626 in Fig 24. Fig. 27 is an elevation oha die-bar and a portion of the die-bar shifter. Fig-. 28

in a general way a main frame or be is a cross section of the die-bar. Fig. 29 is a plan view thereof showing the dies thereon and a certain feed element or plate at the side of the dies. Fig. 30 is an elevation similar to Fig. 27 but shows a die-bar construction involving an additional feature, the purpose of which will appear later. Fig. 31 is an elevation on a somewhat smaller scale of a portion of a die-bar showing in what manner a certain locking-plate indicated in section engages with each die-bar. Fig. 32 is a view of the type faces of a number of assembled typebars and represents the maximum and minimum limits of length within which the strip or ribbon is severed in the present machine to form typebars. Fig. 33 is aperspective view of a cam-shaft and shows the operative connection therewith of a key for releasing the shaft and permitting it to be rotated.

Similar characters of reference designate corresponding parts in all the figures of the drawings. a

The machine set forth in the drawings attached to the present specification is adapted to receive a blank in the form of a continuous strip or ribbon supplied to it from a coil of the same, for the sake of convenience, to form on the edge thereof a succession of composed tyCpes suitable for typographic puroses an to remove from thestock of the blank excessmaterial that may have been forced beyond the sides thereof in consequence of operating upon its edge to form types and type-separating spaces.

. he frame work of the machine com rises an various accessories and framework details or elements carried thereon or thereby. The main frame as shown herein comprises a bedplate of suitable form and construction to support the various operative parts of the machine, and is designated in a general way by B. This bed-plate B may be supported by suitable legs I) as shown. The type-forming dies may be selected 'and brought successively to the type-forming point in any appropriate manner and by any suitable mechanism. For the purpose of illustration, however, in the present machine the various dies for forming individual types are designed to, be brought to the ty e-forming oint manuallythat is to say, t e dies are liand adjustable from a position in which they are incapable of forming ty es into a position in which they are severa y ca able of so operating. To admit of this a justability the dies may conveniently be carried by a head or carrier designated in a general way by C, which, as here constructed, is movable about an axis defined by a shaft 2 extending from o osite'ends of the head (see particularl ig. 2) and journaled in bearings forme in or sup 'orted by an upright 3 adjacentto one. end. of thechead, and;

ward froin the bed-plate B, and it will e' noticed in the present construction that the bearing afforded by the upright 4 for the shaft 2 is in bearing portions at the extremities of the end arms 4* and 4 of the upright,

and that these bearing portions do not together extend the whole length of the upright; hence a s ace is provided betweenv them within whic 1 there is attached a fixture to the shaft referred to 'at length hereinafter.

The mounting of the head C is shown and has been described to be such as to enable the same to be angularly adjusted and such adjustability permits, in the present construction, any one of a number of lines of dies extending axially of the head to be brought into juxta osition to or in line with the point where a ie is to operate upon the edge of the blank to form a type and for the purpose of temporarily locking thehead in its angularly adjusted position a lockingde vice is preferably provided consisting in this instance of a spring finger 5 secured to the bed-plate B, (see, for instance, Fig. 10,) whose upper angular or detent portion 5 is adapted to enter any one of'a number of.

notches 5 formed in a plate ,5 affixed to the head 0. The resiliency of the finger 5 causes its detent portion 5 to s ring into a notch when the same is broug t opposite.

such portion, thereby retaining the head in position, although ermitting of the detent to be withdrawn sufficient force is applied to the head through the medium of any suitable manuallyoperated device, herein shown as a handle,

mm the notch when-a.

designated in a general way by C", to turn the head to another rota'rial position.

As constructed and organized in'the present case and as set forth in the drawings there is provision not only for an angular; adjustment for the purpose of bringin different dies into operative relation wit the} blank, but for an adjustment longitudinally of the head as well, whereby the capacit of the machine is increased overthat whip would exist if'the former adjustability alone I 57 were present, This 1atterthat is, end-l wiseadjustment is rendered eifective for the=purpose set forth by supportin or form: ing a. number of dies each being risignated in a general way by (1 upon a die-bar D, 5a

number of which latter are mounted in suitable recesses c in the head C corresponding to and so related to the described notches 5* that a bar is in line with the type-forming point when the detent portion 5 of the lock ing finger 5 has entered a notch. The sey eral bars D may be slidably fitted in any appropriate manner to their respective recesses, the present construction embodying a longitudinal tongue or rib (Z which extends inwardly into the guide space and is fitted to a corresponding channel in the face of the bar.

The dies d may be of any suitable character and provided with accessory parts or un- 5 provided therewith, dependent upon the nature of the action which it is des gned shall take place during the process of type formation. According to the present construction and mode of operation and as embodied in the present invention, the blank upon which types are formed is fed across the type-forrring point and a type is produced by a forging operation which causes the forcin or s ueezing of excess material outward atera ly of the blank while the die is operating upon a eferably confined portion of the edge of the l a tter. The confining of the field of action ofthe die for thepurpose'of controlling the movement of the excess material and direct 2.0 ing it sidewise of the bar and for effectively piotecting :an adjacent formed type may be ought about by theeniployinent of retaining walls at the side or sides of the die, endwiseof the blank, thesewalls taking the form in the present machine of longitudinal flanges b, b ron the edges of each bar 1).. The flange which is located forwardly of the forming type when a die is positioned to compress the blank, is here shown as of sufiicient width to 80 form .a space extending into the character field of the next succeeding type to be formed. Furthermore, one of the flanges at the edge of the bar is also shown provided with an opening indicated in a general way by C oppositeeach die through which flowage can take place in the direction of and pfiiirlist the base of the contiguous type- As organized in the present instance a bar D .is .in an adjusted position, so far as the angu ar movement of :the head C iseoncerned when the latter has been turned upon its axis to bring the bar to the lowest point of the arc in which the latter moves, as a result of the rotarial movement of the head. In this osition the bar is adapted to be shifted ength-wise in its guides to bring any articula-r die 6 upon the bar over the b ank by means of a) shifter designated in a general way by E. This shifter E comprises in the form thereof shown ,a shifter bar 6 fitted to slide insuitable openings in the direction of the lengthwise movement of which the several bars 1) when rotarily adjusted are capable. These openings through which the shifter bar 6 moves are here shown to be formed in plates 6", -6" secured to the arms 4, Prof the upright 4 m such a position as will bring the shifter bar in line with a diebar D when this latter is located in line with the type-forming point as pointed out above, in which position the die-bar may be adjusted in its guides by means of the shifter operably controlled by a convenient handlever designated.inageneral way by F. This hand-lever F is shown fulcruined at its end by a pin or stud indicated by 7 to an elevated portion of the bed-plate B and as engaging with a pin 8 extending from the shifter bar and passing through an elongated opening 8 in the hand-lever. Preferably a locking device will be combined with the l1and-lever F. for retaining it in a definite position corresponding to an adjusted position of the shifter bar 6. The device here shown comprises a detent 9 (see Figs. 6 and S) thrust outward through the bore of an opening in the extension 9" (sod the latter figure) by a spring 9 into engagement with a notch for-ming one of a series of notches 10 presented by a locking-plate 10. The notched portion of this lockingplate 1O preferably has in general a curved outline as seen in Fig. 6, the better to secure a proper action of the detent 9, which detent it is-evident from the'forego ing description, while being held yieldingly in engagement with .a notch, yet permits the lever F to be turned upon its fulcrum to bring the detent into another notch corresponding to the movement of the shifter bar, 6 for the purpose of bringing another .die .to the type-forming point; I

Referring now to the illustrated construction for engaging the die-shifter E witha die-bar D, the shifter-bar 6 is .prov-idedwith 9'5 a cross slot 6 adapted to engage with a projection or tooth 6", formed at the end. of each die-bar by cross notching the same, (see 6 Fig. 2 and Figs. 27, 29 and 30,) when the head C is rotated to bring the die-bar into line with the slidingbar; hence in this position of the parts a movement of the shifter bar serves to slide the die-bar forward in its guide-way, in which it is retained from 'lateral displacement by the previously-mentioned longitudinal ribd the bottom surface of the guide space forms the reaction surface for the die-bar and taking the thrust of the latter during the operation of type-fo.rniing.

The normal or inoperative position of a 1 10 die-bar axially of the head 0 is indicated in Fig. 2 and from this figure it will be noticed that the cross-notch 6 in the die-bar referred to as forming the tooth 6* on the lat. ter is opposite a plate 11. In this ,position that is the inoperative osition-of the diebars the head C may rotated upon its axis from side to side, the plate :11 extending radially inward to slot 11 therein through which slot the shifter-bar 6 moves upon operating the" hand-lever'F, (see, for instance, Fig. I10, and the detailed views in Figs. 24, 25 and26).

Theplate 11 therefore acts as a means for l t 2 5 locklng all the die-bars from lengthwise.

engage with the cross notch 6 in-each die-bar Oncach side of the'120 upon'its axis. qFur 18o" thermore, it will be noticed on examining Fig. 2 that notch 6 in the die-bar indicated (which die-bar is typical of all the others) is of sufficient depth to permit the entering I 5 portion of the shifter-bar 6 to pass inward beyond the edges of the axial groove in the head C forming the guideway for the diebar; hence when the head has been turned while this latter bar is beingmoved lengthwise to adjust the die-bar the head is locked from .rotarial adjustment. Each die-bar I is, in the present case provided with an an cessory part or feed-plate 12 operating to regulate the amount of movement ofjthe blank-feeding mechanism operating 'in "a manner hereinafter referred to at length:

- An indicator device is also shown for facilitating the adjustment of the several dies cl s with relation to the blank during the operation of forming composed types upon its' edge This device, designated in a general way by G, comprises a pointer or arm 13 extending from the shifter bar 6 and moyable toand-fro with itacross the face of an indicator-plate'l l, which, in the present form,

is curved and is attached to an arm 15 whose hub portion 15 is secured to thelshaft 2 of the head 0 in the space between the fixed arms 4', 4* already mentioned. This indicater-plate 14 is shown provided with lines of characters designated in a general way by vg extending lengthwise of the plate and corresponding to the various dies upon the several die-bars D and the parts are so rela j tioned that when the pointer 1.3 .is brought opposite any particular character the corresponding die has assumed its type-making position. a

Z; The present machine, as already stated, is

. adapted to form type-bars from a, continuous rod or ribbon-like blank, designated herein in a general way by H, by first making types upon its edge and then severing portions provided with such types into lengths.

"The strip or rod H may be conveniently supplied to the machine from a coil or roll of the same, shown supported on a suitable reel designated in a general way by K. This to reel K maybe rotatably mounted upon an arm 16 in an appropriate position to deliver the blank H to the guide-slot 17 of a guideblock 18, and to compensate for the changing of diameter of coil as t e blank is consumed,

this arm 16 may be pivoted to the base.

frame B, as shown, to permit it to swin from position indlcated 1n part full an sition therein indicated.

The blank H is fed in a positive manner forwardly m the direction of its length to bring successive and definite portions of its edge into the type-forming point to ermit spaced at such distances from each other as accord with the demands of the art. Such feed movements of the blank take place used to effect such movement.

=1 element sufiices both to form these shoulders bynotchingjthe blank and to engage with'the shoulders so formed-to feed the blank forwardly. This element as constructed in the ratchet thread'andprovidcd with a number vided with an unmutilated thread, which en gaging with the notches h (see particularly the blank. The screw 1 9 is suitably mounted in the guide-block 18 to out notches of a sufficient depth in the stock of the"=blank to "tivelydriven in the present case by the following. mechanism: Attached to the shaft 19 of the screw is a gear-wheel 19 enga with a gear-wheel 20 driven by a gear-w 'ee 21 attached to a shalt 22 and meshin with a. gear-wheel 23 fixed with relation to t e gearable hearings in whichit is turned under control of the mentioned feed element or plate means: It may be'premised at the outset that takes place in the present organization imthe feed movement thereof and afterwar As shown,,particularly in Fig. 6, a single \form am le shoulders with which the rear. {end of tie screw may engage and is posiwheel 20, Thisshaft 22 is mounted in suit a forward feed movement of the blank H- mediately following the formation of a type and while the blank is being withdrawn from part dotted lines in Fig. 5 to the dotted po- H of the formation of composed types t ereon intermittin l since durin the formation of Y present case consists ofa screw 19 with a of longitudinal flutesor scorings 19 producw ing a series of teeth.

On examining Fig. L6, which represents the'carrier L in its lowermost position, it is evident that as thecarrier moves upward in the direction of the stationary die-bar D the lCVOl' 26 will be tilted about the point at which it contacts with the surface of the feed element 12in such a direction as to slide the pawl idly over the teeth of the ratchetwheel 24. A awl-actuator is herein shown in the form 0 a link 28 extendingu ward through an opening in the base frame and operative from a cam 29 affixed to an interniittingly rotating shaft 30 (adverted to at length later) to move the pawl in the opposite direction and turn the shaft. 22 in its bearings. This actuator it may be stated has been left upon the previous rotation .of the. shaft 30 in its lowermost position with a space between its cam-roller'and the )eriphcry of the cam 29, or at least'the initial movement of the shaft when it starts rotating 2; suflices to move the cam in a direction to permit the ascent of the cam-roller;- hence the ilpward movement of the outer or pawlcarrying end of lever 26 will not be resisted by cam 29 or the actuator link, but the latter will be likewise elevated. When the carrier L now returns to its-original or lowermost position, during the operation of the machme, the resirrgance to motion exerted by-the shaft {223ml by reason of the fact that the pawl engages with a tooth of the ratchet-wheel will cause the inner end of the lever 26 to swing downwardly, carrying this end away from the feed-plate l2 and leaving the lever free to be swung about its fulcrum on the bracket-arm 27 by the action of rotating cam 2!) transmitted through the actuator link.

Some types, and hence the dies for forming them, being ordinarily wider than others, it is essential for the production of satisfactorily composed ty es-that feed movements of greater lengths be imparted to the blank for the wider types. This variation in the degree of feed movement-may be secured by providing the fced-p1ate 12 with suitable depressions, designated in a general way by 12, pro erly relationed to the different dies, and the ottom of each of which depressions forms the contacting oint for the end of the lever 26 with the fee -plate, for it is evident that as the carrier L rises the .end of the lever notch 38 byan elevating spring 42.

however, the push-rod is depressed by ment, and. a crank-'handle VT, extending I from a crank w, which in turn is secured to the shaft 22, may be provided for feeding blank through the machine by hand.

, It has been stated that the shaft 30 has an intermittent movement, that. is, a move- 'ment effective for securing the proper sequence of operations as the present'machine is 'organize( and constituted. Such movement' in the present organization results from the operation ofthe; following constructive details under the'con-trol of the o erator. To-the maindriving-shaft 320i 0 machine, which. maybe provided :'-with. a

pulley 33 for effecting its continued rotation and journaled in suitable bearings 32 32 1' there is affixed a worm 34 engaging with and servingto rotate a worm-wheel '35 acting as driver for the n'ientioned shaft 30 but normally disconnected therefrom. The latter shaft is rendered operative from the main driving-sh aft, however, when a catch ordetent 36 at the end of a lever 37 is withdrawn from a shoulder formed by a notch 38' in a locking disk- 39 affixed to the shaft 30. This lever 37'is shown fulcrumed intermediate its ends to a projection 37 a on the under surface of the bed-plate B and tiltable from the upper surface of the latter to release the locking disk 39 b means of a push-rod A0 extending th-rougi an opening in the bedplate and surmounted by a finger piece 41. Normall this push-rod 40 is elevated and the cat-c 1 36 held in a position to enga e the r hen,

the operator the locking disk is released and the rotating main driving-shaft 32 drives the shaft-1O through the engaged worm 34 and worm-wheel 35 through some suitable device. The construction here shown for causing the rotation of the shaft 30 from the worm-wheel 35 and which nevertheless permi-ts the continued rotation of the wormwheel' when the shaft is locked from rotation comprises a frictional connection of the parts, to wit; the worm-wheel 35 is looseli y mount-ed upon its shaft but somewhata; justable lengthwise thereof to Permit of clamping of its hub against a collar 43 affixed to the shaft 30. The clamping showlrcomprises a nut 43' engaging with a threaded portion of the shaft and against a washer .43 between which and the
