TYPE-WRITER.

SPECIFICATION forming part of Letters Patent No. 570,453, dated November 3, 1896.

Application filed August 22, 1895. Serial No. 560,116. (No model.)

To all whom it m/cty concern:

Be it known that I, LOUIS K. COE, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Type-Writers; and I do 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention is an improved paper-carriage for type-writers, its object being to eliminate the shifting mechanism, automatically supply the paper, and make visible writin g. This I obtain by the mechanism illustrated in the accompanying drawings, of which Figure 1 is a sectionalview. Fig. 2 is apart of the same view enlarged, showing the parts in different positions. Fig. 3 is an elevation of the right end front. Fig. 4, is a vertical section through the cylinder on line X X of Fig. 1. Fig. 5 is an elevation of the righthand end. Fig. 6 is a section on line Y Y of Fig. 1. Fig. '7 is a view of the left-hand end of the cylinder. Fig. Sis a front elevation of the same, and Fig. 9 a section of the cylinder and bobbin B In the drawings, S is a shaft journaled in the type-writer frame A and has a spiral groove SG, commencing at its left hand and extending to the middle of the shaft, and having upon the other half of the shaft the peculiarly-formed groove SE, which, co1n mencing on the right hand of the shaft, passes nearly around it in a vertical plane, then slants to the left at an oblique angle for a cer: tain distance, then around the shaft parallel to the first groove to a point on a line with the commencement of the slant SE, then slants again to the left parallel with the first slant and in the same horizontal plane, and so on toward the middle of the shaft, forming a continuous groove having a slant to the left at regular distances, the slants all being upon the same side and parallel and in the same plane.

0 is a hollow cylinder having hearing at each end upon the shaft S, the right-hand bearing 0 projecting three-eighths of an inch from the cylinder and the left'hand bearing 0 projecting three-sixteenths of an inch from the cylinder, or in that proportion. The righthand bearing forms a collar carrying the handle-barL and large pinion P The outer end of the collar C has an annular rib R, provided with ratchet-teeth, as shown in Fig. 5. The large pinion P has a projection P from its bearing P to which is pivoted the dog or pawl P, having an extended end P, adapted to engage the ratchet-teeth of the rib B.

To the bearing P of the pinion I are pivoted the arms L of the rod L, which has a depending arm. By moving this depending arm to the right or left the pinion P may be made to slide correspondingly on thecollar C S is a pawl pivoted in a slot in the collar (3 so as to engage and enter the groove SE and follow it as the collar is revolved.

S is a spring underneath the outer end of the pawl for the purpose of keeping it in position in the groove.

The outer end S of the pawl S is beveled to the left. This pawl is located atsuch a point in the collar 0 that when the pawl P is in engagement with the ratchet-wheel R the pawl S is in its groove SE, but when the pawl P is drawn out of engagement with its ratchet-wheel R, as it will be when the depending arm of the rod L is moved to the right, thereby moving the large pinion P on the collar (3 to the left, the large pinion P will slide upon the beveled end S of the pawl S and force it, S out of the groove SE, as will be hereinafter mentioned.

The cylinder 0, as previously mentioned, is loosely journaled on the shaft S. Across the longitudinal surface of the cylinder 0 is a slot SC about one-fourth of an inch wide. WVithin the cylinder and just at the edges of this slot are two steel rollers R and R which maybe about three thirty-seconds of an inch in diameter, and pressing against the under side of these rollers is a large rubber roller R all being journaled in the ends of the cylinder, with the shaft of the roller H extending through the right-hand end of the cylinder and having upon its outer end outside of the cylinder a pinion 1, adapted to mesh into the large pinion P when the same is moved to the left on the collar 0 so that when the pinion P is in the position just described and the cylinder is revolved by the means hereinafter described the pinion l on the end of the roller R will run around upon P as the cylinder is revolved and thus revolve the roller R Just back of the roller R and a little to one side is a bobbin R upon which is wound the paper used in writing. This paper is a continuous sheet and may be provided with perforations transversely dividing it into the usual sheets of paper used in type-writing. They may be, of course, of any length, and it is understood that the paper must be manufactu red expressly for use in this style of a type-writer carriage and that the bobbin must be wound with this paper before placing it in the cylinder.

When first placed in the cylinder, the sheet is drawn out by and between the rollers R and R and extends around the cylinder and into the slot SC and between the rollers R and R S is a spring within the cylinder on the left side thereof adapted to enter the spiral groove SG and move through it as the cylinder is revolved, which action, it will be observed, will draw the spring to the position shown in the dotted lines in Fig. 1. hen the pawl S in traveling through the groove SE, has reached the slanting part of the groove, the spring S will force the cylinder 0 along the shaft S to the right, the pawl S traveling in the sliding groove until it has reached the end of the slant, which will check the movement of the cylinder along the shaft S, the spring S at the same time having been relieved of its tension.

L is a handle-bar, connected at the rear of the machine at T to the spacing-bar T, connected to the keyboard in the common way. The rod L is connected to the handle-bar L through the lug L on the handle -bar L The handle-bar L rocks loosely on the collar 0, the collar serving as a pivot for the bar, as shown in Figs. 1, 2, and 5.

Depressing the spacing bar tips the rear end of the handle-bar L and with it the rod L, which it carries, thereby turning the large pinion P engaged by the arms L and thus pushing the pawl P upon the ratchet-wheel R and turning it over one tooth, which, it will be observed, also turns the cylinder C.

Releasing the spacing-bar allows the pinion P to go back, carrying with it the pawl P, which will then engage the next tooth of the ratchet-wheel B. At each depression of the spacing'bar the handle L will be rocked, which communicates motion to the cylinder, as just described, through the ratchet and pawl R P, which movement, being the space of one ratchet-tooth at a time, is adapted to give the required space for the letters, the spacing-bar being depressed as each letter of the keyboard is struck, as in the ordinary typewriter-carriage.

The pawl S moving in the groove S, guides the cylinder 0, as previously stated, in re volving, and when the pawl S has reached the slanting groove SE the spring S forces the cylinder to the right, as heretofore described, the length of the slant SE being the distance desired between the lines of the writing upon the outside of the cylinder. It will thus be seen that the letters are spaced automatically and that a newline is presented when the cylinder has completed one revolution, and that the written line will extend around the cylinder instead of across it longitudinally, as is common. \Vhen the cylinder 0 has thus revolved and moved to the right regularly, and the pawl S has reached the right end of the shaft S, the blank sheet will have been filled with writing.

To remove the written sheet and obtain a blank sheet, the operator presses the depending arm of the rod L to the right, which, as previously described, forces the large pinion P to the left and into mesh with a smaller pinion P on the end of the roller R thereby drawing the pawl S out of the groove SE and the pawl P out of the ratchet-teeth of the wheel R. Then the operator pushes the cylinder C to the left along the shaft S, which, by reason of the spring S running in the spiral groove SG, causes the cylinder 0 to revolve, and the revolving of the cylinder revolves the roller R within the cylinder for the reason that the pinion P in mesh with the pinion P which is held against rotation by the arms U of the rod L, is carried around the pinion P by the revolution of the cylinder, thus revolving the roller it The revolution of the roller unwinds the paper from the bobbin R and pushes it out between the rollers R and R and draws it in between the rollers R and R which draws the written sheet within the cylinder.

An empty bobbin B may be placed within the cylinder for the purpose of winding the paper upon it after it has been written. The bobbins R and R are placed within the cylinder by passing them through the holes 1 l in the end of the cylinder, with their inner ends in bearings in the opposite end of the cylinder.

at 4 are bars placed across the openings 1 1 and rest in the'sockets 3 and 5 on the end of the cylinder. These bars are each provided with a bearing 2 for the left-hand end of the bobbins and R"; The bobbin R has a central shaft 6, carrying within the bobbin the coiled spring 7, one end of the spring secured to the shaft 6, the other to the wall of the bobbin, and when placed within the cylinder and the written paper passed over it the tension of the spring 7 will cause the bobbin to revolve just enough to take up the slack of the paper between the roller R and R and, as the typewriter is run, to continue to wind the paper passed between these rollers upon the bobbin.

Having thus described my invention, what I'claim as new, and desire to secure by Letters Patent, is-- 1.
