Hy inventionv relates to typewriting machines and more particularly to mechanism for feeding an-d guiding stencil cards and the like. A v, The main object of my invention, genere allystated, is to provide comparatively s1m A 1Q A further object of my invention is to proe vide means suchvas are referred to above that may readily be incorporated'in existing type- Writing machines without modifying, or materially modifying, the .existing structural features of such machines. Y To the above and other ends which will hereinafter appear, my invention consists in the features of construction, varrangements of parts and combinations of devices set ticularly pointed out in the accompanying claims.

structural features thereof, except to 'Vomit some feature and add the devices of the present invention. It should be understood, however, that the invention is not restricted to embodiment in said machines.
The Remington portable machine includestype bars 1 pivoted at 2in a type bar segment 3 to strike against the platen 4 nearthe top Y thereof land slightly forwardl of a vertical transverse plane extending through the axis of the platen. The platen is supported in the usual manner on a"removable spindle 5y Said end plates 6 y and screw bolt and'nut 11'to the base 0r bedi plate 12 of the carriage." The lcarriage is mounted in the ordinary manner onantifriction rollers 13 by which .the carriage is supported to travel from side to side of the machine 0n a case shift frame 14. v
The usual line spacing mechanism, including a. line spacing handle 15, line spacing pawl 16, regulating device 17, and line spac-l ing wheel 18, is employed `to intermittently feed the platen forward line by line.
In accordance with my pres-ent invention the usual feed rollers, paper table, etc. are omitted. Sheet metal supporting vbrackets 19 are fastened at 20 to the bed plate 12 ef the carriage. Each of these brackets is provided with an inclined supporting member 21 on` Which a card guide and holder, designated as a whole by the reference numeral 22 is detachably and adjustably secured by suite` ableineans that will enable the card' guide as` a whole to be adjusted todifferent positions i `relatively to the printing line and retained in such adjustedpositions. Such means also allows of the r-eadyfsubstitution of one 1n the presentinstance the means in question comprises two series of corresponding openings 23 in opposite side portions 24 of the guide which rest'upon the supporting members 21'of the supporting brackets. Each member 21 carries an upwardly projecting pin 25 fixed thereto and adapted to fit -with n in any one of 'companionopenlngs 23 andhold the card guide in any one of several ad justed positions depending on the openings 23 in which the pins 25 are received. Headed lock screws 2G engagetapped openings in the members 2l of the supporting brackets.
One side of the head of each of these screws is cutV away so that when such cut-away portions are brought next to the side members 24 of the card guide the latter may be lifted olf the pins 25 and readjusted to the desired position thereon. The screws 26 are then turned to bring their heads to overlapping position, as shown, and to bear down on the members 24, thus securely holding the card guide on its supporting brackets.
The purpose in adjusting the card holder inthe manner described is to position `it where a stencil card contained therein will lbe accurately positioned to receive the first line of writing. In som-e instances the naine and address will occupy two` lines on the stencil card. In other instances they may occupy three lines and it sometimes occurs that they will rbe made to occupy four or five lines.` Vith the adjustable means describedthe card holder may be properly ad` justed forward and'back in an inclined plane and set in any one` of, say, four different positions with reference to the printing line, -so as Vto position the card to receive the first line of writing of a two, three or more line.A name and address.
It also will beunderstood that a slightlyv modified forni ofv card guide and holder, shownxdetached in' Fig 4, is interchangeable with the card guide shown in the machine in F ig. 5. The guide shown in Fig. 4 is substantially the same as that illustrated in other of the views except that the holes 23 there-A in are located at lower points on the guide. There isa large variety of stencil cards on the market, son'ierof which have deeper, lower cross bars on the frame than others, as indicated by a comparison of the full and dotted lines in F ig. 6. Therefore, a card of one style may require a slightly different regis-r tration or adjustment than another. By providing interchangeable guides a suitable guide for any character of stencil cardA may be readily employed.
Each detachable and adjustable card guide I 22 comprises a bottom wall 27 which coacts with the lower edge of a stencil card to support it in the guide. Each guide also has v v end walls 28 which coacts with the side edges or a stencil card and front and. rear walls 29 and V30 respectively which overlap the side edge portions oit the card. A card is vthus guided in alsubstantially fiat condition in itsl line spacing movements and a high degree of visibility is provided while cutting the stencil. i
The means by which a card is effectivel fed at each intermittent actuation of the platen will now be described.
Referring more particularly to Fig. 3 it will be seen that two main toothed driving gears 31 are secured to the platen 4 at the ends thereof. The right hand gear 31 meshes with a pinion 32 provided with a supporting shaft 33.k This shaft turns in a bearing sleeve 34 fixed in an arm of a bracket 35. The foot piece 3G of this bracket is secured to the base l2 of the carriage by the screw bolt and nut 11.v A collar 37 is detacliably connected by a pin 38 to the outerend of the shaft 33, thus holding the latter against displacement from its bearing sleeve. Projecting inwardly from the pinion 32 at the center thereof is a pin or shaft-section 39 in which is fixed a laterally projecting connecting pin 40. rllheopposite ends of this pin are received in enlarged openings 4l of a cylindrical coupling member 42 secured on the outer end of a driving shaft 43 which'is arranged above the platen. f As will readily be understood froni'an inspection of Fig. 3, this means for connecting the driving pinion 32 to the. driving'shaft 43 provides, in effect, a universal joint between the two that connects them toV turn'together, but env ables the inner end of the driving shaft toreceive a limited swinging motion in any direc- 'i tion. However, by othenmeans to be described the swinging motion of the shaft is confined to one which is towards and away from the platen, as will presently appear.
The driving gear 31 at the opposite end ofA the platen is positively connected in a like manner with a second, substantially axially aligned, feed wheel which coacts with the opposite side edge portion of the stencil card. The same reference numerals will be einployed to designate the parts of the two sets of feed devices where they are the saine. However, the parts' controlled by the left hand driving gear 3l are mounted in a-slightly different manner from the feed devices previously described, and where the structurev differs such differences will be pointed out.
A shaft auxiliary bracket arm 50 .is secured by Y suitable means-to the left hand ond plate 6 of the carriage and extends up beyond the upper edgey of said end plate. instance Iemploy two positioning pins 5l and 52v and a screw 53 to hold the bracket Y arm in place.` `An inwardly projecting bearing sleeve 54 is riveted to said bracket arm-50 and provides a bearing for the supporting' shaft 33tL of theleft hand driving pinion 32.
, The outer end'of 'this shaft is tapped to re- In the presentv lift) ceive the stem of a headed screw 55.l The head of this screw overlaps the outer end of the bearing sleeve 54 and prevents axial displacement of the shaft 33a. OtherwiseV the driving connections are the same as those previously described.
A In order to control the movement of the feed wheels 44 away from the platen, or to releasing ineffective position, and also in order to. apply anelfective individual spring pressure on each of the feed wheels 44, I have provided the following construction:
Two supporting brackets 56 are secured by screws 57 to the bed plate l2 of the carriage. Each bracket 56 has a headed pivot pin 58 on which is pivoted a bell crank lever 59. 'Ihe forwardly extending arm 60 of each of these lleversis apertured to provide a bearing opening 61 in which the innerendL of the conipanion driving shaft 43 is received with a loose fit. Each lever 59 therefore constitutes a pivoted support for the inner end of the companion shaft 43 and guides and controls it for swinging movement up and downtowards and from the platen.
The downwardlyextending arm 62 of each lever 59 has its lower end connected to one end of a contractile spring 63, the oppositeV end of which vis connected to an arm 64projecting fromthe associated bracket 56. Each lever arm 62 has an ear 65 which carries a laterally projecting pin 66. Each pin is received in a slot 67 in an upright crank arm 68 secured to a rock shaft 69. This shaft is supported in bearing openings in the brackets 56, and at its left hand end extends beyond the companion bracket where it is vprovided with an upstanding crank arm 70 that terminates in a linger piece 71 by which the shaft may be turned.
It will be seen from an inspection of Fig. 2 that the width of each slot 67 isr greater than the diameter of the pin66 received therein, to provide a slight lost motion. It follows therefore that each spring 63 exerts its force individually` on the companion feed wheel 44 to force it towards the platen and againstthe stencil card withwhich it engages. When, however, the finger piece 7l is pulled forward both crank arms will be turned in a like direction and both bell crank levers 59 will be rocked to elevate the inner ends of the driving shafts 43 and the feed wheels 44 carried thereby. |Ilhis enables the operator to introduce a stencil card beneath the feed wheels be pressed against the platen and to be slightly bent near the printing line, as shown, so asto hug the platen snugly at this point and thus provide for a clearer cutting of the stencil cards by the types. The operator then proceeds to return the carriage and line space the platen in the usual manner wit-h'theaid of the line spacing handle 15. rllheturning ofthe platen causes the positively driven feed wheels 44'to be turned: to feed the card, which is held between said wheels and the platen, one line space. Each successive' feeding of the card a line space distance is effected in a like manner. When a stencil card is finished it may be fed out from under the feed Vwheels and removed by turning i the platen vforward with the usual linger wheel 72. Or, if desired, the feed wheels may be released as previously described and the coinpleted stencil withdrawn and a new one introduced, as pointed out. l
In order to facilitate reading the stencils I prefer to employ carbon paper or the like back of each card as it is being written or' cut in the machine. By placing'the effec-v tive face of the carbon next to the stencil some of the carbon product will be introduced into the outline of each character as it is produced on the stencil card, thereby enabling the operator to readily read the inscription on each Vstencil as it is cut. l
metal is extended forward and down from this point and connects with a substantially U-shaped paper deflector 75 that extends around beneath the platen to the front thereof. rIhe deflector 75 and support 73 may thus be formed from a single vpiece of sheet metal which has ears that enable it to be secured to the brackets 56 by screws 75a. A strip of coinparatively heavy carbon paper 7 6 may be coiled into a loose roll 77 that rests in thecon-v tainer 73. The free endof the strip is passed f over the joint 74 where the roll support and deflector are joined, thence between the deflector and platen andup past the printing line beneath the stencil card with the effec.-
- strip corresponds substantially to the length of the opening 78 in the frame 45 of a stencil card. This is inorde'r that the carbon strip may cover the length of the relatively thin stencil paper 8O but will not be brought beneath the frame'45 ofthe stencil card and be y pressed thereby againstthe platen. The reason for this is that I wish to avoid automatically feeding the carbon strip with the stencil cards, as they are successively line spaced,
' and which would result in unnecessarily us- -cut or torn off fromV time to time.
In order to retain the carbon coil'or roll against axial displacement from the support 73, I have provided a retaining device, designated as a whole by the reference numeral 8l.
rlhis device can 'be made of sheet metal and comprises side wings 82 and a cross bar S3 and has forwardly extending arms 84 apertured to provide bearing` openings by which thev retaining' device is pivotally supported on the rock shaft 69. The device is retained in its effective, Fig; 2, position by gravity, wherethe wings 82 embrace the ends of the carbon roll 77 and hold it against axial displacement. When the retaining' device is turned up on `its pivotal support out of the container 73, the carbon roll is free to be removed or a new one introduced. It Ywill be seen that when the retainingdevice is in effective position the cross bar 83 bears down against the loose coil or carbon roll 77 and prevents it from uncoiling beyondthe cross bar- In Figs. 6 and 7 I have shown two common forms of a large variety of stencil cards that may be readily employed in machine. It will be understood that there is no more difficulty in using the card shown in Fig. 7 than there is in using the card shown in 6, since the deep top 85 of the frame shown in lig.v 7 extends up to the rear ofthe platen free from interference by any of the vparts carried by the carriage. Mforeover, the unobstructed space up to the rear of and between the feed wheels 4A facilitates the ready removal of completed stencil cards and the introduction of new ones.
By the present construction the feed wheels are arranged above the platen and beyond the upper ends of the guide walls of the card holder and out of the range of adjustment of the latter. Moreover, the feed wheels and card guide are each supported on the carriage Y independently of the other, so that the feed Wheels do not interfere with the independent detachment, replacement and .adjustment of 7 `the'card holder, nor does the card holder interfere with, nor is it affected by, the throwing off or releasing` of the feed wheels or the'independent spring pressure exerted by each feed wheel against thecard.
It will be understood, moreover, that all of the parts which coact with a card to guide and feed it are carried by a carriage which is mounted for case shifting movement. If desired, therefore, upper and lower case characters may be cut on the stencil cards without interference from the card guidingand feeding devices.
7arious changes may be made in the concarriage and cooperative with a card to guide it substantially in a flat condition upwardly and rearwardly in an inclined plane, two substantially aligned driving shafts which ter-V minate at their inner ends at or near the associate side' edges of a card in said guide, a
