TYPE-WRITING MACHINE,

SPECIFICATION forming part of Letters Patent N0. 760,066, dated May 17, 1904.

I Application filed January 18,1902. Serial No. 90,340. (No model.) i

To aZZ whom it mag concern.-

Be it known that I, W LTER S. HALLooK, of Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Type-Writing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in type-writing machines, and more particularly to paper-feed mechanism, the object of the invention being to provide simple and efficient means for regulating and controlling the feed of thepaper 1 through the carriage of a type Writing machine such as employed with a machine of the key-wheel class and to so construct and arrange the feed devices that an extensive range of adjustment will be afliorded and so that the paper will be firmly held while being written upon.

With this object in view the invention consists in certain novel features of construction and combinatlons and arrangements of parts,

as hereinafter set forth, and pointed out in the claims.

Figure 1 is a plan view of a type-writing machine embodying my improvements. Fig. 2 is a face view-of the carriage. Fig. 3 is a sectional View of the carriage. Figs. 4, 5, 6, and 7 are views illustrating the paper-feeding mechanism.

1 2 represent the end plates of the carriage of a type-writing machine, between which a paper-feed roller3 is mounted in elongated bearings, and with this roller a smaller rub her-covered feed roller-4 cooperates to effect the proper feed of the paper.

The roller 3 is normally pressedtoward the roller 4 by means of springs 5, and said springs 5 with a knob 6.

A rod 7 is secured at its ends to the end plates of the carriage at a point slightly below the feed-rollers, and this rod serves to support the front edge of a paper-holder 8, said holder having perforated lugs 9 loosely mounted on the rod and the edge of the holder adjacent to these lugs is disposed in close proximity to the feed-rollers immediately under the smaller roller 4. The holder 8 is made of sheet metal bent so as to be oblong in cross-section, its upper edge terminating in a lip 10, disposed in close proximity to the larger feed-roller 3 and above the smaller feed-roller 4. The

paper-holder is made shorter than the feedrollers, so that the paper will project slightly beyond one end thereof, and thus enable the,

operator to ascertain when the lower end of To further facilitate the ascertaining of this information, the ends of the paper-holder are cut away, as shown at 11. A rod 32constitutes a bottom support for the paper-holder and is connected thereto by means of a loop 33, secured to said holder and embracing the rod. Where the loop embraces the rod, the

latter is notched, as shown at 34, to permit the paper-holder to be moved a limited distance.

longitudinally when the larger feed-roller 3 is thus moved, as and for the purpose hereinbefore explained. When the lower edge of a sheet of paper is inserted between the feed-rollers and said rollers are rotated, (by the devices hereinafter described,') the paperwill be made to enter the holder and move around thein-. terior surface thereof and be guided again between the feed-rollers by the lip at the upper edge of the holder. The sheet will be thus wound within the paper-holder until its upper end will be in properposition to re ceive the first line of writing.-By causing the sheet of paper to pass the secondtime between the feed-rol'lers after entering the paper-holder said sheet will be prevented from buckling or becoming rumpled within the holder, the sheet will be firmly. held during a line of writing, and the feeding of the paper will be accurate.

A red is secured to the upper ends of the end plates of the carriage and to this rod a paper-guard is attached. To this plate a paper-guide rod 36 is secured, and on said rod a scale 37 is mounted, said scale consisting of a strip of metal or celluloid bent around the rod 36, and thus occupying very little space, so as not to cover the lines of writing, as would be the case with a flat scale-plate. At one end of the carriage the feed-roller 4 is provided with a'pinion 12, adapted to mesh with a larger pinion 13, mounted on a pintle projecting from one end 2 of the carriage. knob 14 is secured to the hub of pinion 13, and between said knob and pinion a thumblever 15 is loosely mounted. A spring 16 is wound on the hub of lever 15 and secured at one end thereto, the other end of said spring being secured to the carriage to return the lever to and maintain it in its normal position in engagement with a stop 17, preferably integral with one end plate of the carriage.

The lever 15 is provided with an arm 18, to

the free end of which a dog 19 is pivotally attached and adapted to engage the larger pinion 13 when the lever is pushed forwardly, a spring 20 being attached at one end to said dog and at the other end to the lever. When the lever returns to its normal position, the dog will be pulled away from the pinion by the engagement of a hook or tooth 21 thereon with a pin 22 on the carriage. The lower end of the lever 15 is made to form a toothed segment 23, adapted to mesh with a mutilated pinion 24, mounted loosely on the extended journal of the feed-roller 4 alongside the pinion 12 thereon. The mutilated pinion is provided with a hub which terminates in a knob 25, and within said hub a spring 26 is located and serves to maintain said mutilated pinion in engagement with the toothed segment, but

permit the disengagement of these parts for the purpose of adjustment, as presently explained. The mutilated gear is preferably provided with six teeth, so that when the lever 15 is pushed the paper-feeding rollers can be moved six notches, or, in other words, six spaces, the toothed segment engaging the blank part of the mutilated pinion after the last tooth thereon has been passed and be thus prevented from further movement. It is apparent that by adjusting the teeth of the mutilated pinion relatively to the first tooth of the larger pinion 13 the throw of the lever 15 can be regulated for the number of spaces it is desired to move the paper at each. operation of said lever. A spring-pressed dog 27 is adapted to normally engage the pinion 12 on feed-roller 4 and insure the accurate movements of the feed-rollers to feed the paper space by space. When it is desired to move the paper some distance without regard to the space between lines, the dog 27 may be moved out of engagement with the pinion 12, and for this purpose said dog is provided with a long arm 28, adapted to be moved by an L- shaped lever 29, mounted on the end of the carriage, and to be maintained out of contact with the pinion by a shoulder 30 on said lever.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a type-writing machine, the combination with'a paper-holder, having a longitudinal opening in one side, .of two feed-rollers, one located within the holder at the opening therein and the other located wholly outside the holder opposite the opening, means for feeding a sheet of paper into said holder and twice between said rollers, and means for operating said rollers to feed a sheet of paper into said holder and twice between said rollers and to withdraw the sheet gradually from said holder and present it to the printing mechanism of the machine.

2. In a type-writing machine, the combination with two paper-feed rollers arranged in horizontal alinement to feed paper upwardly to printing mechanism, of a paper-holder inclosing one of said rollers, said holder having an opening with one edge disposed between and below the axes of both rollers, a lip at the other edge of said opening, said lip disposed in close proximity to the periphery of the inclosed rollers and means for operating said rollers to feed paper into and also out of said holder.

3. In a type-writing machine, the combination with two feed-rollers, of a sheet-metal paper-holder made oval in cross-section and having a longitudinal opening in one side, said holder inclosing one of said rollers and having one edge of the opening therein disposed between the rollers, a lip at the other edge of said opening, said lip disposed near the periphery of the inclosed roller, and means for operating said rollers to feed the paper into the holder and twice betweensaid rollers and for withdrawing the paper from the holder and presenting it to the printing mechanism of the machine.

4:. In a type-writing machine, the combination with two feed-rollers, one of which is movable longitudinally, of a paper-holder arranged to guide the paper between said rollers, and meansfor permitting longitudinal movement of said holder when the feed-roller is moved longitudinally.

5. In a type-writing machine, the combination with carriage feed-rollers and a paperholder cooperating therewith, a loop on the bottom of said holder, and a rod fixed to the carriage, and having an elongated notch to receive the loop on the paper-holder and permit longitudinal movement of the latter.

6. In a type-writing machine, the combination with the carriage, a large feed-roller and a small feed-roller, of a pinion on the journal of one of said rollers, a pinion mounted on the carriage and meshing with said first-mentioned pinion, a lever mounted on the hub of the pinion on the carriage and carrying a dog IIO to engage said pinion and devices cooperating with said lever to regulate the throw of said lever and the extent of feeding of the paper at each movement thereof, and a paper-holder arranged to receive a sheet of paper and direct it twice between said rollers.

7. In atype-writing machine, the combination with two paper-feeding rollers, and a pinion on a journal of one of the feed-rollers, of a larger pinion mounted on the end of the carriage and meshing with said first-mentioned pinion, a lever mounted on the hub of the larger pinion and carrying a spring-actuated dog to engage said larger pinion, a toothed segment at the end of said lever, a mutilated pinion adjustably mounted on the journal of the feed-roller and meshing with said toothed segment, to control the throw of said lever and regulate the number of spaces the paper is fed when the lever is moved, and a paper-holder arranged to receive thepaper and direct it twice between said rollers.

8. In a type-writing machine, the combination with the carriage, and two paper-feeding rollers, of a pinion secured to a journal of one of the feed-rollers, a larger pinion meshing with the first-mentioned pinion, a lever carrying a dog to engage the larger pinion, a spring for returning said lever, a spring-pressed dog adapted to engage the teeth of the first-mentioned pinion, a lever adapted to engage said dog, move it away from engagement with said pinion and retain it out of such engagement, and a paper-holder arranged to receive a sheet of paper and direct it twice between said rollers.

9. In a type-writing machine, the combination with the carriage, of paper-feeding rollers mounted therein, one of said rollers capable of limited longitudinal movement and a paperholder arranged to receive a sheet of paper and direct it to the feed-rollers, said paperholder being movable longitudinally.

10. In a type-writer carriage having two rollers between which the paper passes in feeding, the combination of the said rollers with four pinions, two of which are complete, and two having teeth through only a portion of their circumferences, for the purpose of limiting the rotating distance of the active one by the obstruction offered by the solid portion of the other, and a paper-holder to receive a sheet of paper and direct it to said rollers.

11. In a type-writer carriage, the combination of two rollers between which the paper passes and a pinion attached to the active roller receiving motion from an interlocking pinion limited in its locating distancesby a free mutilated pinion working parallel to and in line with the active-roller pinion, and a paper-holder arranged to receive a sheet of paper from the rollers and direct it twice to said rollers.

In testimony whereof I have signed this specification in the presence of two substribing witnesses.
