These tubes or bars are preferably in alinement, and each of them is parallel with the platen. hile there are two paper-guides 30 shown, 1 will describe in detail only the one shown at the right-hand end of the platen, it being understood that both guides may be constructed and mounted in the same manner. Contained within the bar 28 is a support or arm 29, which may be moved within said tube in the direction of the length of the platen. The inner end of this arm 29 is secured to a paper-guide 30, as indicated at 31. This paper-guide 30 is preferably made resilient and extends from the support 29, which by preference is adjacent to a vertical plane extending through the axis of the platen.

- One end of this coiled spring 32 is secured to an end of the platen-frame, as indicated at 33, whereas the opposite end of said spring bears against an extension 3a of the paper-guide.
- this coiled spring 32 surrounds the so-called bar 28.
- the main body portion of the paperguide 30 is preferably struck up from a single piece, which is first formed into a blank of the character indicated in Fig. VI of the drawings.

- To the main body portion of the guide is secured an independently movable flexible arm 38, which is apertured. as indicated at 39, for the recep tion of the feed-roller 37.
- these feedrollers constitute margin feed-rollers.
- the guides 30 are located at portions of the circumference of the platen different from those at which the guide-fingers 23 and the feed-rollers 11 are located. It will likewise be seen that these paper-guides 30 are adapted to receive the paper from the guidefingers 23 and to direct the paper forwardly and rearwardly from the platen.
- the paper-guide has a series of notches in the extension 34 on the guide and that the free end of the spring 32 is provided with a finger-piece 41, by which the free end of the spring can be removed from engagement in a notch 40.
- the guide When the spring 32 is disengaged in the manner specified, the guide may be moved in the direction of the length of the platen, as indicated in dotted lines in Fig. III of the drawings.
- the inward movemcnt of the guide 30 may be limited by the head of a screw 41 (see Fig. VII.) which permits the guideto be readily removed when desired. While both of the paper-guides 30 have been shown adjustable, I desire it to be understood that one of them need not be adjustable.

- This crank-arm 45 is connected to a rock-shaft 47, that is mounted in suitable bearings on the platen-frame, and has a fingerpiece 48 connected thereto at its opposite end. A movement of the finger-piece 48 from the initial position (shown in full lines) will cause the rock-shaft to be oscillated and a longitudinal movement to be transmitted to the rod 18 in the direction of the arrow in Fig. II.
- a full movement of the finger-piece 48 will cause the various portions which cooperate with the cams 16, 17, and 44 to be brought to rest on each of these cams, which is indicated in each instance by the numeral 49, so so that when the support or bar 18 is moved its full limit in the direction of the arrow in Fig. 11 the main feed-rollers 11, the guidefingers 23, and the paper-guides 30 will all be simultaneously moved away from the platen and maintained in such position until the finger-piece 48 has been again moved back to the initial position.

TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 774,924, dated November 15, 1904.
Application filed November 20, 1900- Serial No. 37,095. (No model.)
To all whom it may concern.-
Be it known that I, FRANZ X. WAcNER,a citizen of the United States. residing in the city, county, and State of New York, have invented certain new and useful Improvements in Type- VVriting Machines, of which the following is a specification.
My present invention relates to type-writing machines, and more particularly to the mechanism for guidingand feeding the paper in such machines.
The object of my invention is to provide a simple and efficient mechanism whereby either wide or narrow sheets may be written on with equal facility; and a further object of the in ventionis to provide in such mechanismaconstruction whereby the written portion upon the paper is presented in an unobstructed view to the operator at all times.
Myinvention consists in the novel arrangement and combination of parts, to be hereinafter described and claimed.
In the accompanying drawings, wherein like reference characters refer to corresponding parts in the various views, Figure I is a central sectional view of atype-writing machine, the section being taken from front to rear of the machine. This view shows sufficient number of'parts of a type-writing machine to illustrate my invention. Fig. II is an enlarged detail bottom view of the carriage with portions omitted and broken away. Fig. III is an enlarged detail front view of the carriage with parts broken away. Fig. IV is a detail front view of one of the paper-guides. Fig. V is a side view of the same. Fig. VI is a plan view of the blank from which the main body portion of the guide is struck up. Fig. VII is an enlarged detail top view of one of the paper-guides.together with the parts which cooperate therewith. In this view certain of the parts are broken away for the purpose of clearer illustration.
While 1 have shown in the accompanying drawings one form or embodiment of my invention in connection with a front-strike typewriting machine and while the invention is particularly adapted to such machines, it should upper or lower case characters.
be understood that the invention may be employed in type-writing machines of a differcut character.
Upon referring to Fig. I of the drawings it will be observed that the frame 1 0f the machine suitably supports a pivoted type-bar 2, which is operatively connected with a slide 3, that in turn is operated by a bell-crank lever 4. This bell-crank lever 4: is operatively connected to a key-lever 5, by means of which motion is transmitted to the parts to operate the type-bar. It will be understood that a separate type-bar movement is employed for be moved by suitable means in a vertical direction to shift the platen in order to write The platenframe 7 is provided with the usual fixed paper-table 10, which guides the paper to the platen. From an examination of Fig. Iof the drawings it will be seen that the lower end of the paper-table terminates on a line where the main feed-rollers 11 are mounted, and so that the. periphery of the feed-rollers practically forms a continuation of the paper shelf. 0 These feed-rollers 11 may be of any suitable number and extend throughout the length of the platen. The feed-rollers are preferably independently rotatable and are all mounted upon a rod 12, which is secured at its ends .to 5 spring-arms 13 14: and may be held connected tothese spring-arms by leaf-springs 14 (See Fig. I.) The spring-arms 13 14 are deflected downwardly at their ends, as indicated atv 15, so that they extend into the path of the cams 9 16 and 17. These cams are carried by a suitable rod or support 18, which may be moved in a longitudinal direction, as will be hereinafter more fully described- A movement of the rod or support 18 in the direction of the arrow in Fig. II will cause the cams 16 and 17,
through their contact with the fingers on the arms 13 and 14, respectively, to force said arms against the tension of the spring thereof to simultaneously convey all of the main feedrollers 11 out of contact with the platen or to a position where they are no longer effective to cooperate with the platen to feed the paper. hen the main feed rollers 11 have been moved in the manner just described to what may be termed the inoperative position. the paper which may be contained between the platen and the feed-rollers is free to be moved by hand in any direction or to any position so for as these feed-rollers are concerned.
Extending from one end of the platen-frame to the other and secured against movement in the platen-frame is a rod or support 19. Upon this rod 19 is placed a plurality of sleeves 20. Each of these sleeves 20 is provided with adjusting means, such as a set-screw 21, by which the sleeve can be secured in the adjusted position, whether the adjustment be in the direction of the length of the platen or in a direction at right angles thereto. Each of these sleeves 20 is provided with a spring-arm 22, which is united by a pivotal connection to a paper guide or finger 23, as indicated at 24. The spring-arm 22 has an extension 25, with which a cam 26 is adapted to cooperate. It will be observed that each of the guide-fingers 23 is curved throughout at least a portion of its length to conform to the curve of the platen. Furthermore, the guide-lingers are each pivoted at or near the center thereof, so that a spring-pressure may be evenly distributed throughout the length of the guide-finger. The rear ends of some of the guide-lingers are curvedoutwardly from the platen, as indicated in Fig. l of the d raw ings. and some of the guidefingers project beyond the lixed paper-shelf 10 and are in substantial alinement with the peripheries of the main feed-rollers 11, whereas ,others terminate near the rollers 11. (See Fig.
11.) It will thus be seen that the guide-fingers 23 cooperate with the fixed paper-shelf 10 and the main feed-rollers 11 to receive the paper therefrom and to guide it in its movement with the cylinder. The forward end of each of the guide-fingers preferably extends to a point adjacent to the'printing-line. From an examination of Fig. .11 of the drawings it will be seen that each of the cams 26, which cooperates with a guide-linger 23, is carried upon the rod or support 18 and moves therewith. These cams may be moved longitudinally upon the rod or support 18 in order that each cam may be adjusted to compensate for any adjustment of its cooperating guide-finger in the direction of the length of the platen. cams in question may each be secured in the adjusted position by a screw 27, which compresses the part which surrounds the rod 18 sufiiciently to secure the cam against movement upon the rod.
From the foregoing description it will be The l l i understood that a movement of the rod 18 in the direction of the arrow in Fig. 11 will cause the main feed-rollers 11 and all of the guidefingers 23 to be simultaneously moved out of contact with the platen or to the inoperative position.
Secured to each end of the platen-frame is a tube or bar 28, which extends toward the central portion of the platen. These tubes or bars are preferably in alinement, and each of them is parallel with the platen. hile there are two paper-guides 30 shown, 1 will describe in detail only the one shown at the right-hand end of the platen, it being understood that both guides may be constructed and mounted in the same manner. Contained within the bar 28 is a support or arm 29, which may be moved within said tube in the direction of the length of the platen. The inner end of this arm 29 is secured to a paper-guide 30, as indicated at 31. This paper-guide 30 is preferably made resilient and extends from the support 29, which by preference is adjacent to a vertical plane extending through the axis of the platen. From the support 29 this paper-guide projects toward the printing-line and extends beyond the forward ends of the guide-fingers 23, as illustrated in Fig. III of the drawings. The paper-guide 30 is curved throughout at least a portion of its length to correspond to the curve of the platen, and a spring 32 cooperates with said guide to maintain it normally in contact with the platen. One end of this coiled spring 32 is secured to an end of the platen-frame, as indicated at 33, whereas the opposite end of said spring bears against an extension 3a of the paper-guide. As indicated in Fig. VII of the drawings, this coiled spring 32 surrounds the so-called bar 28. The main body portion of the paperguide 30 is preferably struck up from a single piece, which is first formed into a blank of the character indicated in Fig. VI of the drawings. By this construction a pair of cars 35 is provided, which constitutes a bearing for the pivot 36 of a feed-roller 37. The feed roller 37 when secured to the paperguide in the manner illustrated is adapted to bear upon the platen when the paper-guide is in the normal position. To the main body portion of the guide is secured an independently movable flexible arm 38, which is apertured. as indicated at 39, for the recep tion of the feed-roller 37. In the particular construction shown and described these feedrollers constitute margin feed-rollers. It will be observed that the guides 30 are located at portions of the circumference of the platen different from those at which the guide-fingers 23 and the feed-rollers 11 are located. It will likewise be seen that these paper-guides 30 are adapted to receive the paper from the guidefingers 23 and to direct the paper forwardly and rearwardly from the platen.
Upon reference to Fig. 111 of the drawings it will be seen that the paper-guide has a series of notches in the extension 34 on the guide and that the free end of the spring 32 is provided with a finger-piece 41, by which the free end of the spring can be removed from engagement in a notch 40. When the spring 32 is disengaged in the manner specified, the guide may be moved in the direction of the length of the platen, as indicated in dotted lines in Fig. III of the drawings. The inward movemcnt of the guide 30 may be limited by the head of a screw 41 (see Fig. VII.) which permits the guideto be readily removed when desired. While both of the paper-guides 30 have been shown adjustable, I desire it to be understood that one of them need not be adjustable. In practice it has been found that it is sufiicient to make the right-hand guide adjustable in the direction of the length of the platen. It will be seen upon reference to the drawings that the supports for the paper-guides 30 are wholly extraneous to the printing-field. By printing-field I mean the space which contains the type-written matter that is. the space between two vertical planes extending from front to rear at the limits of a written line and terminating at that line of the sheet which is in the printing position. Each of the arms 29 for the guides 30 is rigidly connected to an arm 43. In the present instance each arm 29 is provided with a square or angularportion .42 for this purpose and with which an arm 43 is connected. The free end of each of these arms 43 extends into the path of a cam 44, carried by the rod 18, so thata movement of the rod 18 in the direction of the arrow in Fig. II of the drawings will cause the arms 29 of the paper-guides 30 to be rocked on their axes to move the paper-guides out of the operative position and away from the platen. From this it will be seen that the arms 29 constitute the pivotal centers upon which the paper-guides move toward and away from the platen.
The rod 18 and the parts connected therewith are moved by a crank-arm 45, which is united to an extension of said rod by a pinand-slot connection 46. (See Figs. 11 and III.) This crank-arm 45 is connected to a rock-shaft 47, that is mounted in suitable bearings on the platen-frame, and has a fingerpiece 48 connected thereto at its opposite end. A movement of the finger-piece 48 from the initial position (shown in full lines) will cause the rock-shaft to be oscillated and a longitudinal movement to be transmitted to the rod 18 in the direction of the arrow in Fig. II. A full movement of the finger-piece 48 will cause the various portions which cooperate with the cams 16, 17, and 44 to be brought to rest on each of these cams, which is indicated in each instance by the numeral 49, so so that when the support or bar 18 is moved its full limit in the direction of the arrow in Fig. 11 the main feed-rollers 11, the guidefingers 23, and the paper-guides 30 will all be simultaneously moved away from the platen and maintained in such position until the finger-piece 48 has been again moved back to the initial position. The movement of the finger-piece 48 back to the initial position will cause a reverse movement of the parts and the main feed-rollers 11, guide-fingers 23, and paper-guides 30 will again be brought into operative position.
hile the paper-guides 30, the margin-rollers 37, guide-fingers 23, and the main feedrollers 11 are all preferably spring-pressed, it should be understood that by s pring pressed I mean to embrace structures which are either maintained under tension by separate springs or which are maintained under tension by the resiliency of the elements themselves.
From the foregoing description it will be seen that each of the guides 30 may be said to have a finger which extends partly around the platen, the finger being that portion of the guide which is directly connected to arm 29.
By the use of the term bar or supporting-bar in referring to the part 28, which supports an adjustable paper-guide 30, I mean to include all equivalent means for accomplishing the same purpose. It will be observed that by the employment of the paper-guides 30 the paper is received from the guide-fingers 23 and deflected upwardly and rearwardly from the paper-platen, and that the written portion of the paper is at all times maintained within sight of the operator, and that no obstruction whatever to this view is presented by the supports for the paper-guides 30.
From the foregoing description it is thought that the operation of the various features of my invention will be readily understood without further reference thereto.
