- chines and more particularly to means for guiding and feeding wards or stencil sheets in substantially a flat condition in a cylindrical platen machine.

One object of the invention, generally stated, is to provide simple and etlicient means of the character specified A further object of my invention is to provide means, such as those referred to, which are in the nature of attachments that may be readily embodied in typewriting niachines now on the market without modifying, or materially modifying, the structural features of said machines as they now exist.

It still further object of my invention is to provide means whereby the machine may he used for cards or stencil sheets, and for handlinb' the same in substantially a flat condition, or may be readily employed as a typewiitingmachine adapted for ordinary use and in which the work sheets are bent around the platen and thus fed through the machine.

T o the above andother ends wh ch will hereinafter appear, my invention consists in the features of construction, arrange ments of parts and combinations of? devices set forth in the following description and particularly pointed out in the appended claims.

devices and some of the associated parts, the view illustrating a stencil sheet in posi tion to receive the first line of writing. F g. 5 is a detail fragmentary perspective view showing one end portion of the detachable supporting bar together with some of the parts carried thereby. Fig. (3 is a detail fragmentary horizontal sectional view taken on the line ;1 of Fig. 2- and lrmlting in the direction. of the arrow at said line, the parts represented in Fig. 6, however, being the ones at the opposite side of the machine from those represented in Fig. 2. Fig, 7 is a detail fragmentary perspective view showing the latch and some machines where found available and may be used for other purposes than those. setforth.

Some of the ordinary equipment of the machine is removed such, for example, as the ordinary paper lingers and margin feed rollers, and in lieu thereof 1 place devices of my invention which enable me to properly position, guide and feed cards or stencil sheets in a flat condition in the machine;

although, as shown, these devices may be readily removed when desired and the machine is then in condition for ordinary use.

The frame of the machine comprises cor er posts 1 and a top plate 2 over which a carriage is adapted to travel from side to side of the machine under control of the usual letter teed mechanism, not shown. The carriage, as shown in the present in stance, comprises end bars a, front cross bar a and a rear cross bar The front cross oar is grooved for the reception of: anti-friction balls or rollers (i which are likewise received in the oppositely grooved guide face of a fixed rail 7. The rear cross bar 5 is likewise grooved for the reception of anti-friction balls or rollers 8 which are likewise received in the oppositely grooved face of a fixed guide rail 9, the carriage being thus SUPPOlted to travel over the top plate in the usual manner. Acylindrical platen 10 is supported by the carriage to receive the impact of the usual upwardly and rearwardly striking type bars against the front face thereof. The platen is supported by a platen frame 11 mounted on parallel links 12 and a roller 13 is carried by the platen frame and cooperates with a shaft rail 14. The usual paper devices including the feed rollers 15"and 16 are employed to cooperate with a work sheet introduced in the rear of the platen in the on dinary manner. The ordinary line spacing mechanism comprising a handle 17, and a line spacing pawl 18 controlled through intermediate actuating devices 19, 20 and 21 is employed, the line spacing pawl co-acting with a line spacing wheel :22 secured to the platen at the right-hand end thereof. A spring pressed detent roller 23 meets with the line spacing wheel to prevent an accidental displacement of the platen from the position to which it may be turned. A line finder or gage 2+2 is secured by screws to a membe which in turn is secured to the shift rail by screws 27. The usual ribbon vibrator 28 is employed although when stencil writing is to be effected the ribbon is removed. it employ the ordinary initial and final line lock stops 2 and 30, respectively, and -the usual initial and final margin stops 31 and respectively, which are carried by the carriage and co-act with the stop carried by the frame of the machine. Finger wheels 34.- are secured to the platen shaft to effect a rotative movement of the platen.

The parts thus far described constitute part of the ordinary equipment of the Nos.

lO or 11 Remington machines and further detail description thereof is deemed unnecessary.

In the present instance I make the feed rollers 16 smaller than those ordinarily employed in order to facilitate a feed movement of the card or stencil sheet in substantially a flat condition in front of the feed rollers 16 without said rollers interfering with the feed of the sheet, as will be understood from an inspection of Fig. 1.. I also preferably cut away a portion of the top plate, as indicated at 36, and likewise cut away a portionof the type bar segment as indicated at 37.

The attachment whereby i am enabled to handle, feed and guide cards or stencil sheets in substantially a flat condition in the machine, comprises a cross bar 3:38 which, as shown is rectangular in cross section and v is provided at its ends with T-shaped cross heads 39 each of which is provided with a plurality of outwardly pro ecting supporting pins. The pins il) carried by the cross head at the right-hand end of the support-- ing bar are received in apertures in which they snugly fit, said apertures being provided in a forwardly extending bracket arm -11 which is securedby screws to the righthand end plate of the platen frame and projects forwardly therefrom. The cross head at the left-hand end of the S11 porting bar is provided with corresponding bearing or supporting pins 43 which, as will be understood from an inspection of hig. 7, are received in bearings is in. a left-hand bracket arm l-5 secured by s crews 1-6 to the left-hand end plate of the platen frame. From an inspection of Figs. 2, 3 and Y it will be understood that a sliding latch, designated as a whole by the reference numeral 4311's normally held in the loclrin tion, indicated in Fig. 2-, V This spring is secured by a screw bracket arm a and bears at its against the sliding latch. This slotted at 50 to receive the stems 0 screws 51 which are received at tlr; ireaded ends in tapped openingsin the bracket arm The latch is thus supported and guided for sliding movement fore and aft of the nia'chineand is provided with a finger piece s? by which it may be moved to the releasing position. The forward movement of the latch is limited by a lug 52 against which the forward end of the latch is adapted to hear when the latch is moved: to its normal position by the spring itl. Body portions and 5t of the latch are adapted to overlie the pins 43 when the latch is in its locking position, thus preventing a detachment of the supporting bar and holding it rigidly on the platen frame. The latch is also provided with a cut out 55 and a free end portion 56. llhen the latch is moved rearwardly by its linger piece 47* to its releasing position, the cut-out or recess 55 in the latch is brought into register with the rear pin 43, whereas the terminal portion 56 of the latch clears the forward pin 43. At this time the left-hand end of the supporting bar may be lifted out of its bearings 4:4: and a slight endwise movement of the bar to the left at this time is effective to detach thebar, together with the parts carried thereby, from the machine for purposes which will hereinafter more clearly appear. This rigidly with two surrounding sleeves 5?. each carrying a set screw threaded therethrough and adapted to hear at its inner end against the supporting bar to hold the associated sleeve in the position to which it may be adjusted along the supporting bar.

Pins project upwardly from the sup porting bar to co-act with the bearing sleeves 57 to limit the extent of outward adjustment of the latter. Each bearing sleeve supported bar 2-58 is provided supports a rearwardly projecting rigid arm ('30 provided at the rear end thereof with a card guide, designated as a whole by the 1 surface 62 against which the card or stencil sheet is adapted to bear. The outer edge of each guide is provided with a flange 63 which projects at right angles to the plane of the body or fiat portion 62 0f the guide to form a side edge guide for the card or stenoil sheet. This side edge guide is curved at its edge, as indicated at 64, to conform substantially to the curvature of the platen, so that the side edge guide may be brought sutlieiently close to the platen to co-act efficiently with the stencil card or sheet when the latter is introduced into the machine between the card guides and the platen. I

Each supporting arm 60 supports a carrier or slide 65 which is inv the nature of a. sleeve that is rectangular in cross section to conform to the shape of the supporting arm.

Each sleeve or slide is' adapted to move on its supporting arm 60 fore and aft of the machine, and is provided with a depending bracket arm .66 which may be formed integral with the slide 65 and is apertured at 67 to receive a feed roller 68 in the apertured portion thereof. The lower ends of the bracket arms of each slide are turned at 69 to constitute a bearing for a supporting sprindle T0 for the associated feed roller 68. From an inspection of Figs. 3 and 5 it will be understood that each card guide is apertured at 71 to enable the associated feed roller 68 to extend therethrough into contact with the card or stencil sheet located between the guides and the platen, and to bear against said card near the printing line and above the latter as indicated in Figs. 1 and l. In Figs. 1 and at, I have illustrated a stencil sheet or card of the usual construction in position in the machine to receive the first line ofwriting. This stencil card is desig nated as a whole by the reference numeral 72 and comprises arectangular open card board frame 73, a reinforcing sheet 7% and a central. stencil sheet 75. It will be understood from these figures that the feed rollers 68' bear against the stencil card atthe side edge portions thereof above the printing line when-the card is introduced between the guides and the platen. It will also be understood that the side edge guides 63 on the card guides cooperates with the side edges of the stencil card to direct the latter in its introduction into the machine and in the feed of the card in its line spacing movements, thus enabling the card to be properly introduced and squared in the machine and to be accurately fed in a substantially fiat condition. It will also be observed from these figures that the relation of the card guides to the printing line is such that when a stencil card of the character shown is introduced into the machine and the top edge thereof is in register with the upper ends of the card guides, the stencil card will be in position to receive the first line of writing. While the card guides are open-ended, no support being provided for the lower ends of the-stencil cards, nevertheless, they may be accurately positioned in the machine, the upper ends of the card guidesconstituting indicating means to facilitate a proper adjustment of the stencil card. Pressure is ex erted upon the slide or carrier for each feed roller 68 by a coiled expansion spring 76 which bears at one end against the associated slide and at its opposite end against the part 77 of the associated bearing sleeve 57. The force of each spring 76 therefore is exerted to move its slide 65 along the supporting arm or rod 60 and press the associated feed roller (3 against the platen or the card interposed between the platen and said feed roller.

I have provided means whereby both of the feed rollers 68 may be simultaneously released in order to properly introduce a card in position or to effect an adjustment thereof. In the present instance these releasing means comprise a rock shaft 78 arranged in front of the platen and supported to turn in bearings in bracket arms 79. These arms project from sleeves 80 which are angular in cross section and surround the rigidly supported bar 38. The support ing sleeves 80 are tapped to receive set screws 81 by which they may be'secured to the supporting bar 38 in the positions to which they mav be adjusted along the latter. The rock shaft 78 projects beyond its bearings and each end is provided with a finger piece 82 fixedly connected with the rock shaft and held in place by a screw 83. Each finger piece 82 is formed with a depending arm 8% (see Fig. 5) from which extends a laterally projecting pin 85. Each pin 85 is received in and extends freely through an opening in the forward end of a link 86. The rear end of each link is provided with a sleeve 87 which projects laterally therefrom and is received on a bearingpin 8S, headed slightly at its end 89, to prevent the link from being displaced from its pin. Each pin 88 is carried by and projects from the associated slide (35 which carries one of the feed rollers 68. The pins 85 passing loosely through openings in the links 86 afford a relative adjustment between the supporting arms 60, and the card guides and feed rollers carried thereby, without a disconnection being effected between the pins 85 and the links 86. It follows therefore that whatever the relative adjustment between the arms 60 and the parts carried thereby may be, the finger pieces 82 are at all times connected with the slides 65 and are effective to simultaneously release both of the feed rollers 68 carried by the slides. Thus, a depression of either finger piece 82 causes the shaft '78 to be turned, thereby producing a forward movement of both of the pins 85 and the links 86 controlled thereby. This is effective to move both of the slides 65 forwardly against the pressure of the springs 76, thereby releasing both feed rollers from the stencil card. The pins 59, hereinbefore referred to, prevent a relative outward adjustment between the supporting arm 60, and the parts carried thereby, to such an extent that the pins 85 can no longer eo-act with the links 86 to eifect a release of the feed rollers. between the arms 60 is effective to bring about an adjustment 0" the card guides and feed rollers 68 longitudinally of the platen toward or away from each othenso as to accommodate the devices to cards of different widths. It will be understood that the movement of the feed rollers into and out of engagement with the card, through an actuation of the releasing means or other wise, is effected independently of the card guides which are of rigid construction and are rigidly supported on the bar 38 in a position where they may at all times co-act with the cards irrespective of the positions of the feed rollers.

As shown, each card guide crosses the printing line so that each guiding surface 62 and side guide 63 extends above and below the printing line and is effective to receive the card when it is first introduced into the machine and ccurately guide it to the feed rollers 68 and-to the printing line, and assure an'accu ate positioning and feed of each card in the machine.

Should the devices carried by the supporting bar 38 interfere with the feed of the work sheet in the ordinary manner when the latter is introduced in the rear of the platen and bent around the same, the latch 47 may be moved to the releasing position and the supporting bar 38 and the parts carried thereby removed as an entirety from the machine. It is essential that at this time some means be'employed to cooperate with the ordinary work sheet to hold it in. position against the platen at the printing line and aid in the forward feed of the work sheet. Any suitable means may be employed for this purpose which will. not interfere withthe use of the stencil card feed devices, In the present instance I have employed a feed roller 90 which extends throughout, or substantially throughout, the length of the platen above the printing line. The spindle or shaft of the feed roller is reduced at its ends and is received in bearing openings in supporting arms 91 fixed at their lower ends to a rock shaft 92. It will This relative adjustment' bu seen from an inspection of Fig. 6 that this rock shaft is reduced at its ends, at 93, where it is received in shouldered bushings 91 which in turn are received in bearing openings in the end plates of the platen frame 11. These bearing openings are usually employed for another purpose which need not be describ'ec. The outer end portions of the rock shaft 92 are flattened on the sides thereof, as at 95, to fixedly connect crank arms 96 thereto. Each crank arm has an opening, the contour of which corre sponds to the cross section of the shaft at each end thereof. A headed screw 97 is received in a tapped opening at each end of the shaft to hold the associated crank arm 96 on the shaft. Contractile springs 98 are connected at their upper ends to the crank arms 96 and at their lower ends to screws 99 which are received in tapped openings in lugs 100 projecting from the end plates of the platen frame. A finger piece 101 is secured by screws 102 to the left-hand supporting arm 91 so as to provide convenient mains for releasing the feed roller 90 from cooperation with the platen or the paper thereon. It will. be understood that the powerof the springs 98 is exerted through the crank arms 96 and rock shaft 92 to press the feed roller 90 against the platen; but that this pressure may be released at any time by a forward movement exerted on the finger piece 101. It will be understood that the position of the feed roller 90 is such that it does not interfere with the feed of the card in a flat, or substantially flat, condition, said feed roller at this time "emaining in the rear of the card and out of contact there with, and so disposed that it will prevent an accidental backward bending of the card to an extent which would injure it, as will be understood from an inspection of Fig. l. The position of this feed roller, moreover, is such that it may be employed at any time with work sheets which are introduced in the rear of the platen and brought around and fed over the platen in a curved condition, said feed roller maintaining the paper against the face of the platen so as to conform to the curvature thereof at and nearthe printing line.

It is believed that the operation of the devices for writing stencil cards or the like will be understood from the foregoing description. The feed rollers 68 are first released through an actuation of one of the finger pieces 82 and the card is introducedbetween the card guides and the platen as indicated in Fig. the top edge of the card registering with the upper ends of the card guides. The finger piece 82 is then released and the feed rollers 68 will clamp the card in place. The card is then in position to receive the first line of writing, assuming that the carriage has been moved to the limit of its movement to the right. After this first line is completed the line spacing handle 1'? may be actuated in the usual manner a; return the carriage to the beginning of a new line and to effect a line spacing movement of the platen thereby effecting a feed of a card to begin writing the second line thereon. After this line is written the card is removed. assuming that but two lines are to be written. thereon. The removal. of the card may be effected by a lorward feed of the platen produced by one of the linger 1. In a front-strike typewriting machine,
