Appncanon sied December 11, 1911. ,serial No. 664,991.

To all whom 'it may concern:

Be it known that I, JoHN PURDY, al citizen of the United States, and resident of the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specitication.`

My invention relates to typewriting machines and more particularly to machines for preparing or writing stencil plates or cards, and the object of the invention, gen-` erally stated, is to provide comparatively simple and eflicient means of the character specified and by which the stencil plates or cards may be quickly introduced into the machine and properly squared 'and positioned to receive the first line of .writing and may be introduced into and fed through the machine in a flat condition. l

To the above and other ends which will hereinafter appear, my invent-ion consists in the features of construction, arrangements of parts and combinations of devices described in the following specification and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 a fragmentary front elevation showing the upper portion of a typewriting machine embodying my invention. FigfQ is a fragmentary side elevation of the same with parts in section. Fig.`3 is a fragmentary detail perspective view of one of the feed rollers and some of the associated parts. Figui is a fragmentary detail perspective view of the release key and some of the asscciated parts. Fig. 5 is a detail perspective view of the side edge gage.

I have shown my invention in the present instance embodied in a Monarch machine and have only shown so much of said machine as may be necessary toarrive at an understanding of my invention. It should be understood, however, that the invent-ion may be embodied in various'stylesof type-v writing machines employing a cylindrical or rotative platen.

rI`he frame of the machine comprises-cornerposts 1 surmounted by a top plate 2. Fixed oppositely grooved guide rails are secured to standards 4 by screws 5. standards are fixed to and project upwardly from the top plateiof the machine and are adapted to -support the carriage in its movement from side to side of the machine over theltop'plate. The carriage comprises a guide bar 6 oppositely groovedr at the top and bottom thereof to receive anti-friction balls or rollers 7 which are likewise received .in the oppositely grooved bearings in the The guide bar G constifixed guide rails tutes a rear cross bar of the carriage from which project forwardly extending side or end bars 8, provided with bearingsto receive a platen shaft 9 on which a cylindrical rotative platen 10 ismounted. It will be understood that the carriage in` its movement over the top plate isimpelled by the usual carriage spring (not shown) and is controlled lby the usual escapementmechanism which I have not deemed it necessary to illustrate. 'A line spacing movement may be transmitted to the platen by the usual means cooperative with a line spacing wheel 11 to effect a step-by-step rotative movement of the platen. Projecting upwardly from the end bars 8 of the carriage are the usual lugs 12 and 13 apertured to receive the ends of a rod 14 fixed in its bearings and held in position by screws 15 and 1G. This cross bar supports the usual erasing shelf 17 and margin paper .fingers and feed rollers 18 and 19 respectively. A combined platen and carriage scale plate 20 is supported in the usual manner beneath the printing line, indicated at a. y

The construction thus far described constitutes part of the ordinary equipment of the Monarch machine and'further detailed description thereof isdecmed unnecessary, it being understood that the usual upwardly and rearwardly swinging type bars are adapted to strike against the front face of the platen. I

-I have provided the following additional or supplementary equipment by which thel machine may be readily converted into a machine for preparing or writing stencil plates'and by which the stencil plates may be properly positioned in the machine to receive the tirstline of writing and may be introduced, positioned and fed through the machine in a fiat condition. Anl auxil- These sol iary plate,21is secured to theusual depending lugs 22]'011 the top plate by headed screws 23 received in-tapped openings in the lugs.

The upper edge of the plate 21 is bent f or-v Wardly at right. angles to the body portlon4 whole by the reference numeral 25. Thesestencil plates' are ordinarily made vwith a comparatively thick'rectangular pasteboard frame-26 which is covered by a comparatively thin stencil e sheet .27.

l,It will' loe-seen upon referenceto Figs. 1f

and 2 that when the stencil plate or card is .introduced into the machine the bottom edge thereof squared and properly positioned against the support 24 which is carried by the top plate of the machine, and that when 1 thus squared the lstencil late is in a posi! tion to receive the first ine of writ-mg Si@ thereon. It will be seen-moreover, thatthe stencil late is maintained in a fiat condition in ront of the platen and, as will hereinafter more clearly appear, may be -fed in such condition upwardly during the .line 85 spacing movement of the platen. The plate 21 is apertured at 28 to enable a vibrator lever 29' to project therethrough. A plate 30 is secured by a screw 31 t the plate 21. This plate 30 is likewise apertured at32 to 4o register with the opening 28 to receive the vibrator lever v29 therethrough. The plate 30 is bent forwardly at 33 beneath the card support and extends upwardly at 34' above the card support to form a pointer which is in alinement with the printing' point, indi cated at Xin Fig. 1. This pointer performs a two-fold function; thus it indicates on the stencil plate, the printing point and at the same time constitutes means for preventingv the stencil plate from being displaced forwardly at the bottom edge thereof fromthe support 24. Italso coperates'` with the scales on the scale plate 20 when a stencil vplate is removed from the machine in order to indicate the posit-ion of the carriage in its line of travel.

From an inspection of Figs. 1 and 2 it will be seen that a sheet metalbracket 3.5 is secured to the upwardly extending 'lug 12 on.

the right-hand end bar of the. carriage by the screw 15 which secures the cross bar or rod 14 in position. l'This bracket plate is bent at right angles to its length, as indicated at 36, so as to pass through the inner 66 side ofthe right-hand end bar 8, and is secured thereto fat its forward end .by av screw opening 40 in a yoke-like member 41, one

and rearwardly to orman arm 42 which terminates in a finger piece orke 43 by which the yoke may be turned-on its pivot 39. A headed pin 44 extends laterally from the arm 42 and is engaged by one end of a Wire spring 45. This spring is coiled about a headed pin 46 whichV projects inwardly from the bracket arm 38. The opposite end of the spring is bent to the right at 47 where bracket 35, so that the force of the spring ,is exerted fto' tend to move the arm 42 upwardly and tov turn the yoke-like member 41 in the direction of .thearrow in Fig. 4. A

vopening corresponding in shape to the cross section of the splined rock shaft. From-an inspection of Fig. v4 it will be understood that theaxial center ofthe rock shaft is in alinement with the axis of the pivot 39 and that the spline 49 connects the rock shaft to the yoke 41 and arm 42 to turn therewith. This splined rock shaftis arrangedabove the platen and above the front. face thereof and extends throughout the length yof the carriage and is received at its opposite end in a bearing opening in asheet metal bracket 50. The bearing opening in'the bracket 50 to limit. the longitudinal movement of the rock shaft to the left.

From an inspection of Fig. 1 it will be seen that the longitudinal movement of the rock shaft 48 to the right is limited by the right-hand end thereof abutting thelheaded pivot 39. The bracket. 50 has a foot piece 51 formed -thereon and bearing againstthe top of the left-hand end bar8 ofthe carriage, in order to l.support the forward end of the bracket.

the carriage by the screw 16 which connects the cross bar 14 to the carriage. ,j

From the foregoing description. .it will be understood that the right-hand. supporting bracket 35 for the splined rock shaft isseof by screws 37 and 15 respectively, whereas the rear end thereof by the screw 16. This mannerv of connecting the .two 'brackets right-hand bracket to the carriage, butto secure the lefthand bracket in such a manner that the forward end thereof may be slightly flexed to the left. in order to disis cylindrical and the end of the splilie 49 bears against the inner face of the bracket The bracketv extends rear-I wardly'and is connected at its rear end tovcured at both the front and rear ends there? the left-hand bracket 50 is secured only at therefore is effective to'rigidly secure lthe 37. An vupwardly extending arm 38 of the bracket 35 has a headed pivt 39 riveted. thereto. This pivot, as w1ll be seen` upon reference to Fig. 4,'is received in a bearingv arm of the yoke'bein extended' downwardly sol its rests against the bottom portion. of' the .splined rock shaft or rod 48 is received in y an opening in the arm 42 of the yoke, such iso engage it from the left-hand end of the rock shaft 48 and enable vthe shaft to be withdrawn from the bearing on the yoke 4l at the right-hand end of the rod.

Two sheet metal hangers, each designated as a whole by the reference nun'ieral 52, are mounted for a limited pivotal movement on the splined `rock shaft 48. Referring more particularly to Fig. 3 it will be seen that each hanger is provided with parallel ears 53 having cylindrical bearing openings 54 for the reception of the body of the splined rock shaft 48. Each ear islikewise apertured at 55 to receive the spline on the shaft. Each aperture .'35 is wider than the thickness of the splinein order that a slight pivotal movement of the hanger may be effected independently ofthe rock shaft.

yA leaf spring 56 bears at its free end against the forward edge of the splineftf and the spring is looped at 57 and is perforated to receive freely -therethrough a screw 58. The body portion of the hanger 52 is likewise perforated toreceive the screw freely therethrough; the head 59 of the screw bearing against ythe rear'side of the hanger, whereas a nut GO is threaded onto the forward end of the screw. By adjustingeaeh nut 60 toward the head of the 'screw the looped portion of the spring may be flexed to increase the pressure of the spring on the spline. It will be seen that by this arrangement an individual `adjusting means is appear.

provided for each hanger, and that each hanger may be moved toward and away from the platen against thepressure of the spring' 5G independently of the other, for purposes which will hereinafter more clearly Each hanger carries -an inwardly off-set margin feed roller 6l connected to the hanger by a headed pivot screw 62, received at its threaded end in a tapped opening in the block-like portion G3 on the hanger. Each margin feed roller as shown in the present instance comprises a metal roller having a knurled periphery and an outwardly extending hub G4. The tread of each feed roller is therefore oH-set inwardly from the hanger which carries it. These rollers are preferably arranged in front of the platen adjacent to the printing line in a position where ,they are adapted to cooperate with the side Aedge portions of a stencil plate, while the latter is maintained in a flat condition in front of the platen and at the printing` line, and while 1t is supported on the stencil plate or card support Q4. In the present instance the rollers'bear against the platen above theV printing line a a short distance. l

Solder-ed or otherwise connected to the inneixear 58 of each hanger is a plate 65 provided with an inwardly off-set bent arm 66. This arm is prolonged to form a deiectmg finger G7 which extends from the front of through the deflecting finger.

the rock shaft or rod 48 downwardly and rearwardly toward the platen, said finger terminating adjacent to the platen as shown in Fig. 2. Each finger tis'tands at an inclination to the plane of the stencil plate or card when the latter is properly positioned in the machine. Each detlecting iinger 67 is also arranged in position where a vertical fore and aft -ypla-ne extending through the tread of the associated feed roller will likewise extend longitudinally It will be seen therefore that the -deiiecting lingers are in positions where they will co-act with the uppery or leading edge of the card or stencil plate nealr the side members ofthe frame thereof and in rear of the stencil plate to deflect the upper edge thereof forwardly to clear the rock shaft 48 and to cause the tcartLto pass upwardly in front of said rock shaft.

It will be understood that the construction is such that each hanger, and the deflecting finger 67 which is connectedI therewith, vis capable of being adjusted on the rock shaft 48 longitudinally thereof in order that the marginv feed rollers may, if desired, be adjusted to different posit-ions longitudinallyv of the platen, so as to present different lengthwise portions of the platen to the impact ofthe types. To maintain the hangers and margin feed rollers against relative adjustment longitudinally of the platen I have connected the hangers by a tlexible-metal strip 68 which extends longitudinally of the platen and may be connected at each end to a hanger by solder or other suitable character of connection. This strip therefore maintains a fixed relation between the marginv feedrollerI 6l and between the deiiecting iingers G7, considered longitudinally of the platen, although the connecting strip 68 does not prevent a relative and limited pivotal movement of the hangers and the parts carried thereby by reason of the flexible nature of the strip. The connecting strip 68 however does not prevent the hangers and the parts carried thereby from being justed to. difllerent positions longitudinally of the platen if desired; but merely maintains them properly spaced apart to coperate with a stencil plate of a given size in order that the feed rollers and detlecting fingers may co-act with the frame 26 of the stencil plate and not with the covering 27 thereon where it spans the rectangular opening in the frame.

It should be understood that the rock shaft 1-8 is turned by the spring 45 to exert the force of said spring through the margin feed roller 6l against the side bars of the stencil plate or frame, but that, nevertheless. any inequalities in one side of the. frame will cause the margin feed roller 61' which 30 cooperates therewith to be deflected away spring56 without causing a corresponding' from the platen against the force of its movement of theother margin feed roller. The margin feed rollers ltherefore act under the force of the spring 45 to bearagainst the frame Vof "1e stencil sheet or plate and each roller i also acts individually against the frame .under the force of itsspring 56. By this construction an efficient selfregulating feed may be effected vfor-'the stencil plates and each stencil plate is compressed by the 'margin feed rollers against the face of the platen near the printing linel in o rder to effeet an upward feed of a stencil plate vvl'iile it is maintained in a fiat condition. TheJ deiiecting fingers 67 assure a feed of the stencil plate'to the forward side of the rock shaft 48 Where'the rock shaft does not constitutev anobstruction to the operators view of the plate asthe Writing proceeds. j y

If at any t'meit is desired to release the pressure of the margin feed rollers lon a.

stencil plate a-depression of theiinger piece 43 is effective to turn the rock shaft 48 and latter, and is likevvise supported independently'of the means by which .the stencil sheet is fed and guided-in its line spacing moves ment;\that the feed rollers 61 are separate from the lsupport 24 by which the lower edge of the cardis supported and that said feed rollers are also supported independently .of

the support 24 by which the card or stencil plate is supported in position When'it is rst.-

4 It will also be seenV that the construction is such that it introduced into lthe machine.

is inthe naturev of an' attachment which may be`readily applied to existing forms of -machines such asl the Monarch machine Without .modifying the structural features of that machinerand. that When the rock shaft 48 lis detachedA fo'm its supporting bracket 501 condition for ordinary use.

50 andV from the yoke 41 the carriage is in While the paper fingers 18 and margin feed rollers 19 -of the ordinary equipment are not employed when the machineis used for stencil'work, I have shown these parts in order to indi cate that the carriage may be quickly adapted for ordinary use and that it is unnecessary to remove the ordinary equipment on the carriage in order to employ the devices ofmy invention thereon.l When thevrod 48v vand the parts carried thereby are removed in the manner described, and the plate 21 is detached and replaced by theordinar s front plate of a Monarch machine Whic 'carries ribbon vibrator equipment, the machine Will be in condition. for ordinary use for correspondence and the like.

I have provided a side edge gage, which isshown in detail in Fig. 5, toaidin prop erly positioning the stencil plates in the machine..4 This side edge gage is designated as a Whole by the-reference numeralv 69l and comprises an angular plate, one of the angular members 7() of which is in a plane at right angles to the axis of the platen and is in position to vcoperatewith the righthand side edge of a stencil plate or .card when the latter is introduced into the machine, as shown in Fig. 1. The otlieranguvlar portion of the -side edge gage 'is arporton of the right-hand spring 56, and is perforated to receive a screw 58 therethrough. The associate nutGO bearson top of the gage and secures it in place. It will be. seen that the gage is thuscarried by the right-handhanger 52 and maintains a fixed relation with reference to the margin feed rollers 61 and the deflecting fingers 67, considered longitudinally of the` platen. Any adjustment-of the margin feed rollers and deflecting lingers brings vabout a correspond'- in adjustment` of the side edge gage, so that it is at all -times'in a position to properly cop'erate With the right-hand side edge of a stencil plate irres ective of the position to which the feedrolers may be adjusted longitudinally ofthe platen. understood that the contact face of the side edge gage is in a plane which is at rightangles to the -plane of the contact face of the support 24 for the stencil'plates, so' that the contact face on the side edge gagev and -ate vvith'edges of the stencil plate which are lat rightangles to eachother, to properly the machine both horizontally and vertically and obtain a proper positioning of, the stencil plate with reference to the printing line and with reference to thel feeding and guidthe embodiment of'thesev-devies in the. machine provides means by which stencil plates may l be readily introduced' and properly' squared and positioned-Qin the'machinenina be' fed in such conditionv duringithe line it -is by the feed movementsof the platen -thatthe stencil lates are fedto receive lthe dilerent lines o writing Various changesvmay' be 'made withoutranged to overlap and rest on the looped It' Willalso bev the contact :face on .the support 24 cop'er A square the plate when it is introduced intostructural features of that 'machinegthatatcondition; that the .stencil plate'sf-mayspacing movements `of the-platenand that ioo f ing devices which coperate iwith the stencil the combination' of acarriage, a rotative platen, supporting means coperative, `with the bottom edge of a card for squarmg the lcard and supporting it in a flat condition in front of the platen and at the printing line, and spring-pressed margin feed rollers arranged in front of the platen and adjacent to the printing line and coperative with a card near the side edge portions thereof, said feed rollers being independent of rsaid supporting means and independent of the means by which said supporting means receives its support.
