HERBERT H. STEELE, 0F MARCELLUS, NEW YORK, ASSIGNOR TO THE MONARGH TYPE- WRITER COMPANY, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.
TYPE-WRITING MACHINE.
To all whom it may concern.-
Be it known that I, I'IERBERT H. STEELE, citizen of the United States, and resident of Marcellus, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in TypelVriting Machines, of which the following is a specification.
My invention relates to paper controlling contrivances or paper fingers for typewriting-machines and the object of the invention is to provide improved devices of the character specified.
To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a front elevation of the platen and platen carrier of a Monarch typewriting machine embodying my invention. Fig. 2 is a fragmentary front elevation of the left-hand end portion of the platen showing the left-hand paper finger contrivance, parts being broken away. Fig. 3 is a transverse sectional View taken through the platen and showing a paper finger in full lines in normal position and in dotted lines in abnormal position.
In the drawings, 1 is the platen mounted on a platen carrier comprising end bars 2 and a rear bar 3. The paper finger contrivances are mounted on a support or paper finger rod 4 which extends lengthwise of the platen above the same and is rigidly secured at its ends by screws 5 to the end bars of the platen frame or carrier. The paper finger rod is provided with a longitudinally extendingslot 6 at its under side. Each paper controlling contrivance or paper finger device comprises a carrier or hub member which is made up of two hub-like parts numbered 7 and 8 and a connecting neck or web 9, the hubs projecting laterally in opposite directionsfrom the web or connecting.

The hub portion 7 is provided at its front side with a longitudinal slot 10 to afford a passage for the usual erasing plate 11 which is mounted on the supporting device or rod 1, the construction permitting the contrivance to be slid along the supporting rod to desired positions. A key 12 carried by the hub portion 7 cooperates with the slot 6 to prevent the hub from turning on the rod and also to hold it frictionally in ad- Specification of Letters Patent.

justed positions, said key being preferably of the spring type common to the Monarch machine. The hub portion 8 provides a support for an arm 13 which is preferably made of sheet metal and folded so that in cross section it is of an inverted Ushape, the sides of the U at the lower end being compressed so as to provide a contracted end portion 14. Housed within the arm 13 near its upper end is a filler or collar 15 through which passes the contracted end portion 16 of a stud or bearing member, the body 17 whereof bears rotatively in a bearing opening in the hub portion 8. The end of the contracted portion 16 is upset or spread so as to form a head 18, thus clamping the arm 13 between the head 18 and the shoulder 19 formed between the parts 16 and 17 of the stud, the construction being such that said stud and the arm 13 compose a single mem ber or element which is rotatable on the hub or bearing 8. A headed screw 20 is secured in the outer end of the body 17 and cooperates with the end of the hub portion 8 to prevent accidental withdrawal of the stud from its bearing. The contracted portion 14 of the arm is formed with a hole which receives a reduced end portion 21 of a stud whose body 22 extends inward, the stud be ing clamped in place on the arm by upsetting or spreading the end of the contracted portion, thus providing a head 23. The inner end of the stud 22 receives a headed shouldered screw 24E which provides a bearing for a'pressure roller comprising a hub 25 which supports an annulus 26 of rubber or the like.
As is clear from Fig. 3 the arm 13 curves downward and forward over the upper side of the platen and terminates above the printing line so that the pressure roll 25, 26 cooperates with the surface of the platen above the printing line. The arm 13 provides a support for a second arm 27 which is arranged below the'arm 13 and is provided with upturned ears 28 which embrace the arm 13 and are pivotally connected thereto by a pin 29 which passes transversely through the arm 13 and has projecting ends on which the ears 28 are mounted. The arm 27 is provided with an upstanding pin 30 ar-' ranged within the arm 13, said pin providing a support and guide for a coiled spring 31 which is confined between the arm 27 and the roof of the arm 13 and constantly presses said arm 27 toward the platen. The inner projecting end portion of the pin 29 is provided with a circular groove 32 over which is hooked the forward end of a draw spring 33. the rear end of said spring engaging a hook 34 secured to the hub portion 7 The spring 33 exerts a constant pressure on the arm 13 and tends normally to main tain the pressure roll 26 in cooperative engagement with the platen. The lower end portion of the arm 27 is enlarged to provide a plate-like head 35 which extends inward from the arm or body 27 and has formed about midway of its upper edge a notch 36. Two corresponding notches 37 are provided at the lower edge of the head 35 and above these notches the head is formed with slot-s or openings 33. The portions 39 between the notches 37 and the slots 38 provide bearings for a paper guide or finger proper d0, said finger 10 being provided with tabs or ears 41 which engage with the notches 37, the lower tabs cooperating with the portion 39 to provide bearings for the finger 40 on which said finger may turn or rotate slightly on the support or head 35 while the upper ear l1 is bent or hooked forward over the head 35 to provide a stop device for limiting the extent of this turning movement of the finger 40. The construction is such that said finger may move independently of its support both pivotally and bodily, thus compensating for varying thicknesses of paper which may be disposed between the finger and the platen; but independent movement of said finger lengthwise of the platen is prevented by the tabs 39 and 41 engaging with the ends of their respective notches. Said finger extends inward from the support and downward over the front or printing surface of the platen and transversely of the printing line, being curved to conform substantially to the platen face. The lower end of the finger 40 is turned outward as indicated at 4-2 and overlies the usual scale 13 which extends lengthwise of the platen below the printing line thereon. As indicated at 41-1 the finger 10 is cut away to provide an opening through which the pressure roller may cooperate with the platen. 7
It will be understood that preferably there are provided two paper finger contrivances of the character described, these paper fingers being otf-set inwardly toward each other so that the paper may pass under the guiding portions 410 and the pressure rollers 26 and over the erasing plate 11 and supporting rod 4, the side edges of the paper passing between the supporting arms 13 of -the paper finger contrivances.
Normally the pressure of each spring 33 operates to press the associate arm 13 toward the front upper side of the platen and to maintain the pressure roll 26 in cooperative engagement with the platen while the spring 31, acting through the arm 27, maintains the finger 10 against the platen surface. This position of the parts is illus trated in Fig. 2 and in full lines in Fig. 3. Each paper contrivance is independent of the other and one may be swung upward and rearward entirely away from the surface of the platen to the position shown by dotted lines in Fig. 3 without affecting the other for the purpose of facilitating the adjustment of the paper or for any other desired purpose. WVhen both the paper fingers are swung up transversely of the platen to the dotted line position all that part of the paper which has been fed above the scale 43 will be entirely freed from the control of the paper feeding contrivances and may be d awn away from the front of the platen or otherwise handled as desired. To facilitate the release of each paper finger contrivance the lower end of the contracted portion 1% is cut away to form a lip or ledge 1-5 for the accommodation of the operators finger. By applying pressure to the under side of the lip 15 the releasing movement. of the finger is readily accomplished. During the first part of the releasing movement the arm 13 and pressure roller 26 will move away from the platen while the finger 10 will remain in cooperation therewith, a relative turning movementtaking place between the arm 13 and the arm 27 about the center 29. As soon, however, as the upper or rear edge of the arm 27 engages with the under side of the arm 13, the relative turning movement will cease and thereafter the finger eO will move upwardly with the arm 13 and roller 26 about the axis 17 as a center. To limit the upward swinging or releasing movement of the paper finger contrivance, the upper rear end of the arm 13 is cut away to provide a stop 16 which cooperates with the barrel or hub 7, as shown by dotted lines in Fig. 3, to prevent excessive rearward swing of the parts. lVhen the parts reach the dotted line position of Fig. 3 the spring 33 is on a dead center, the line of force being indicated by the dotted line a. At this time the spring 33 will in consequence operate to maintain the parts in the.
abnormal position.
It will be observed that by my present invention I provide a simplified and improved construction of paper finger contrivance or guide and one which not only enables the paper fingers to be adjusted lengthwise of the platen independently of each other but enables them to be entirely thrown off or swung transverselv from the platen surface or released independently of each other; and further that the construction provides for a movement of the paper finger proper on its pivoted supporting arm independent of any other parts.
Various changes may be made Without departing from the spirit and scope of my invention.
What I claim as new and desire to secure by Letters Patent, is
1. In a typewriting machine, the combination of a platen, a support, a carrier adjustable thereon, an arm movably connected to said carrier, a pressure roll supported by said arm, a second arm movably connected to the first arm, and a paper guide movably connected to said second arm.
