TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Nov. 30, 1915.

Application filed August 25, 1915. Serial No. 47,250.

To all whom it may concern:

Be it known that I, CLIo B. YAW, citizen of the United States, and resident of Arlington, in'the county of Hudson, and State ,of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and more particularly to work sheet feeding means.

The main object of the present invention, generally stated, is to provide simple, inexpensive and yet highly efficient auxiliary feeding means by which a stencil card or like may be fed effectively in a cylindrical platen machine in substantially a flat condition, so that the cards or work sheets need not be bent with a consequent liability of mutilating or breaking them as they are being fed through the machine.

A further and important object of my invention is to provide means of the character specified which are in the nature of an attachment that may be readily applied to or detached from typewriting machines now on the market, without modifying the structural features of said machines, as they now exist, and without impairing the usefulness of said machines for ordinary work in which the work sheets are fed around the platen.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices set forth in the following description and-particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the different views, Figure 1 is a front elevation, with parts broken away and parts omitted, of a carriage of a Monarch I tvpewriting machine equipped with the auxiliary feed devices of my invention. Fig. 2 is a vertical fore and aftsectional view of the same, the carriage being shown mounted in place in the machine. Fig. 3 is a detail vertical fore and aft sectional view with parts broken away, the view showing one of the margin feed devices and some of the associated parts, and the section being taken on the line mac of Fig. 1 and looking in the direction of the arrows-at said line.

Fig. 4 is a detail plan view of one of the margin feed devices showndetached. Fig. 5

is a detail perspective view of one form of card feeding mechanism embodying my invention, together with some of the associated parts. Fig. 6 is an enlarged detail sectional view taken on the line g 4 of Fig. 3 and looking in the direction of the arrow at said line. Fig. 7 is a detail perspective view of a modified form of card feeding attachment constructed. in accordance with my invention.

I have shown my invention embodied in the present instance in a Monarch machine in which the invention may be readily incorporated without modifying the structural features of said machine as they now exist, and without renderingthe machine any the lesseffective to perform its ordinary work. It should be understood, however, that the invention may be embodied in other styles of typewriting machines and that various changes may be made to readily effect such embodiment.

In the accompanying drawings I have 7 shown only so much of the Monarch machme as may be necessary to arrive at an understanding of my present invention, 1

parts of the usual equipment of said machine being omitted where it is unnecessary to such understanding. 7

The top plate 1 of the machine supports the usual uprights 2 to which fixed oppositely grooved guide rails 3 are secured by screws 4. These grooved guide rails receive anti-friction balls or rollers 5 which are also received in oppositely grooved rails G of a guide bar 7, which constitutes part of the carriage of the machine. End plates 8 project forward from this guide bar and support a. platen shaft 9 on which the usual cylindrical platen 10 is mounted. The usual paper feed mechanism of the machine is employed, the main paper feed rollers 11 and 12, respectively, a paper apron 13, paper table 1st and scale plate 15 being diagrammatically shown in Fig. 2 of the drawings. The left-hand platen head is provided with a line spacing ratchet wheel 16 with which a line spacing pawl 17 cooperates. This pawl is pivoted at 18 to a. supporting arm 19 operated bv a rock shaft controlled by a finger piece 20.

The usual margin feed devices and erasing shelf or plate employed in the Monarch machine are included in the present construction and by means of which the auxiliary feed devices of my present invention may be detachably mounted in place as will hereinafter more clearly appear. The usual cross rod 21 is arranged above the platen and is secured at its ends to the end plates 8 of the platen frame and supports the margin feed devices for adjustment longitudinally of said cross rod and the platen with which they co-act. This rod also constitutes a support for the erasing plate designated as a whole by the reference numeral This plate is formed with ears 23 which are received in reduced bearing portions of the cross rod and thus support the plate at one end by the rod, the forward edge of the erasing plate bearing against the face of the platen. The rod 21 is formed with a spline groove 2i (see Fig. (3) which extends throughout the length of the rod.

Each of the usual margin feed devices is formed with a bearing sleeve 25 which surrounds the supporting rod 21. Each sleeve co-acts with a spring spline member 26 which is received in a spline groove 21 of the rod 21, to hold the associated sleeve and the parts carried thereby against turning movement 011 the rod 21 but enables the sleeves with the parts carried thereby to be adjusted along the cross or supporting rod. 1- rigid forwardly. extending arm 27 is formed on each sleeve 25 and has pivoted thereto at its forward end an arm 28 which carries an inwardly projecting spindle 29 surrounded by a spacing sleeve and supporting a margin feed roller 30. A springpressed plunger 31 co-acts with faces 32 or 33 on the end of the associated arm 27 to maintain the margin feed roller in either its operative or inoperative position. Each arm 27 has a paper finger 3st pivoted thereto at 35, each finger being formed with an ofiiset outwardly projecting arm 36 provided with a yoke 37 which is substantially U- shaped in cross section. The side members of the yoke are pivoted at 35 to the associated arm 27, said members being connected by a cross plate 38. An expansion spring 39 is received in an opening in the arm 27 which carries it and bears at its lower end against the cross plate 38 of the yoke of the associated paper finger 34. The pressure of each spring 39 is thus exerted to force the associated paper finger against the platen.

A further detailed description of the paper fingers, margin feed rollers and erasing shelf or plate is deemed unnecessary since they are of the usual construction embodied in the Monarch machine, said paper fingers and margin feed roll construction being of the character disclosed in the patent to Seib No. 921,745, dated May 18, 1909, and the erasing shelf or plate being substantially of the character represented in the patent to Nielsen No. 790,652, dated May 23, 1905.

Vhile I have described with considerable detail the margin feed mechanism, it should be understood that this description is primarily for the purpose of showing the manner in which the mechanism in question cooperates with the card feed mechanism in a front-strike typewriting machine to detachably secure said mechanism in place.

From certain aspects of my invention it is immaterial what character of margin feed devices are employed so long as they co-act with the auxiliary feed devices to hold the latter in place and afford a detachment thereof.

One form of the attachment by which the cards or work sheets may be effectively fed in the machine is disclosed in Fig. 5, from which it will be seen that the attachment or device in question comprises a supporting bar, member or plate .0. This supporting member is formed with hearing portions 41 apertured to receive a bearing spindle -12 which forms a support for a two-part hollow rock shaft 13% The inner ends of the hollow shaft are united by a joint comprising feathers or lugs 45 on the inner end of one member of the shaft which are received' in corresponding openings or cutouts 46 in the other member to form an interlocking engagement between the two to cause them to turn together. There is a slight lost motion between the feathers 45 and the walls of the openings 46 in which they are received, as indicated at 47, in order to afford a slight lost motion between the two members of the shaft and thus pro- Vide for a limited independent rotative movement between them, for purposes which will hereinafter more clearly appear. Each member of the rack shaft l3l'-t carries a depending arm 48 fixed thereto in any suitable manner. Each arm i8 is apertured to receive a spindle 49 which is in the nature of a headed shouldered screw secured in place by a lock nut 50. Each spindle projects inwardly from its supporting arm 48 and carries an auxiliary or card feed roller 51, located at or near the printing line and adapted to cooperate with a side edge portion of a card or like work sheet, indicated as a whole by the letter A. Each arm 48 is extended rearwardly above the supporting bar 40 and beyond the member of the rock shaft to which it is attached, as indicated at 52. A leaf spring 53 bears at its free end upwardly against each of the rearwardly extending portions 52 of the arms 48 causing the auxiliary feed rollers 51 to bear against the platen, or the card interposed between the feed rollers and the platen. The outer ends of the springs 53 are secured-at 54 to 13 the supporting member 40. It will be understood that each of the springs 53 acts individually on its associated feed roller 51, this individual pressure of each feed roller by its spring against the card being afforded by the lost motion between the two members of the rock shaft 43-Ai. The purpose of this is to enable each feed roller 51 to exert its spring pressure against the card independently of the other in order to effectively co-act with and feed the card at one side even though the roller at the other side of the card be slightly displaced forwardly i from the platen by reason of any inequality or unevenness in the card. In this manner an effective engagement is at all times maintained between the feed rollers 51 and the card while the latter is engaged by the feed rollers. 5

One of the arms 48 is provided with an' upwardly extending member 55 which terminates in a finger piece 56. By moving the latter rearwardly against the pressure of the associated spring 53, the feed roller 51 carried by said arm is moved forwardly away from the platen or work sheet and the member 43 of the two-part rock shaft is turned. When the limit of independent movement between the-two members of the shaft is reached the member a l will be turned, thus releasing the other feed roller 51 from operative engagement with the card.

The supporting member which carries the auxiliary feed rollers is detachably secured inplace in operative position in the following manner: From an inspection of Figs. 2 and 5 it will be seen that the supportthis end of the member is seated on ing member is formed with depressions or recesses 57 which constitute bearing seats which, in the present instance, cooperate with the sleeves 25 of the margin feed devices to support the member 40 and. the parts carried thereby on the cross'rod 21. The ends or terminal portions 58 of the supporting member 40 are adapted to be received under the connecting members or plate 38 of the paper fingers, as illustrated in Fig. 3, and to be pressed by the spring 39 against the erasing plate 22 and on the cross rod 21 or the sleeves 25 carried;- thereby, and thus clamp and secure the supporting member 40 in operative position.

In attaching the memlier 40 to the'a nachine, one end 58 thereof isEfirst introduced into position. between the spring pressed plate 38 of the associated paper finger and the erasing shelf. The seat 57;, at this end of the member 40 will bear :it this time the sleeve 25 of the associated paper against The other margin feed device will finger. then porting rod until its spring pressed plate 38 extends over the opposite end 58 of the supporting member Miami the seat 57 at the as be adjusted inwardly along the sup-- sociated sleeve 25, and the member 40 will then be held firmly in position. When thus positioned the support 40, together with the parts carried thereby, are effectively supported in operative position ready to receive a card or like work sheet and to cooperate with the platen as the latter is line spaced to effectively feed the card while the latter is maintained in a substantially fiat condition in front of the platen, as indicated in Figs. 1 and 5.

In order to remove merely necessary to effect an placement of the sleeves 25, and the parts which are carried thereby, away from each other when the member 4:0 will be released and may be removed from the machine.

The construction disclosed in Fig. 7 is similar to that disclosed in the preceding figures except that the parts have been simplified. Thus, in the modified form of construction the supporting member 59 is struck up from a single piece of sheet metal formed with supporting ears or hooks 60 which constitute seats to engage the sleeves 25 on the margin feed devices. Ears 61 are likewise formed on the supporting member to receive the spindle 62 which supports the two-part the attachment it is outward disrock shaft 63, 6%. The abutting ends of these members of the shaft are cut-out, as at :65, to provide an interlocking engagement between the two members which causes one to turn with the other, a slight lost motion being provided, as indicated at (36, to alford a limited independent turning movement between the two members of the shaft. A

single spring 67 is secured by screws (38 to and secured in position in the same manner as the previously described attachment and cooperates with the platen in the same manner to effect a feed of the cards.

When I refer herein to a card I use that term in a broad senseto designate more particularly a work sheet such as a stencil card or sheet of the character shown, cards such as are used for card index systems, envelops or any other work sheet which by reason of its thickness or construction renders it dcsirable that it shall be maintained substantially in a flat condition while it is being fed through the machine. It should be understood. however, that the term is not necessarily restricted to a card of the character specified and that from certain aspects of the invention the mechanism may be employed to feed the work sheets in any available manner and may be employed in connection with work sheets of any suitable character.

Various changes may be made without departing from the spirit and scope of my invention.
