TYPE-WRITING MACHINE.

; SPECIFICATION forming part of Letters Patent No. 375,178, dated December 20, 1 87- Application filed March 7, 1887. Serial No. 230.021. (N0 model.)

To aZZ whom it Hwy concern:

Be it known that I, ANSON MILLS, of the United States Army, at present stationed at Fort Grant, in the Territory of Arizona, have invented certain new and useful Improvements in Type-VVriting Machines, of which the following is a specification.

My invention has been devised more particularly with a view to its application to and use with type-writing machines-suoh as the Remington, the Caligraph, the Ham rnond, and others wherein the paper is fed through the machine by feed or pressure rolls. I

It has been my object to combine with such a machine devices whereby the paper may be.

supplied from a continuous roll, instead of in separate sheets, as is now customary, and whereby the said continuous web, after it passes the feed or pressure rolls and has been printed on, may be severed or divided into lengths, as desired. I also provide a receiving or take-up roll mandrel or reel which is arranged to be operated from some appropriate or convenient moving part of the machine, and can, when desired, be used to wind up in roll :form the continuous web of printed paper as it is delivered from the pressure or feed rollers.

The nature of my invention and the manner in which the same is or may be carried into eiiect can best be explained and understood by reference to the accompanying drawings, in which Figure 1 is a plan of a typewriting machine provided with my improvements. Fig. 2 is a longitudinal vertical section looking to the rear, the plane of section passing between the feed-rolls and through the axis of the paper reel or mandrel. Fig. 3 is a side elevation from the side on which the hinged or removable center for the paper reel or mandrel is located. Fig. 4. is a vertical crosssection on line 4 4, Fig. 2. Fig. 5 is a cross-section of a tablet, hereinafter more particularly referred to.

The machine in connection with which I have represented my invention is the wellknown Hammond type-writer now in the market and in general use, it being a machine having in the main the characteristics of that described in Letters Patent No. 290,419, dated December 18, 1883. I have not illustrated, nor shall I describe, the details of the working mechanism of said. machine, because the same are well known, and because, also, they form no part of my invention.

It is sufficient to say that A is the cylindrical shell or case for receiving the paper. B are theiutermittently-operated pressure-rolls, between which the paper passes and is held and by which it is fed at proper intervals;

and O is the arched top plate, over which the paper passes, these .parts being carried by and form part of the paper-carriage, which has a lateral or transverse step by-step movement, as usual in this class of machines.

In the cylindrical shell or case A is placedthe roll or reel of paper which is to be printed on. The shaft or mandrel D of said roll or reel is supported at the ends on centers E F, affixed to the ends of the shell A. The cen ter E is on a spindle which can revolve and is formed as a chuck, being provided with wings a, which enter slots 1) in the adjoining end of mandrel D, so that the two will revolve together. The center F is removable from over the end of the shell A. One convenient arrangement for this purpose is to mount it in a cross-bar, G, hinged at c to the case andheld at its opposite end by a latch, d, which, when disengaged from the bar, will permit the'latter to swing outwardly on its hinge, thus removing it and the center F from the end of the shell and leaving the latter open for the insertion or removal of the shaft or reel or roll of paper. The paper, H, from the roll passes up just as the paper sheet ordinarily does) between the pressure and feed rollers B, and thence up over the top plate, 0. This top plate I use as a convenient place for applying the cutting attachment by means of which the paper web as it is printed on and fed along may be severed into suitable lengths, if desired. One convenient arrangement for this purpose is represented in the drawings. In the top plate is formed a slot, 6, extending crosswise of the machine, and in this slot runs a circular rotary knife, f, which is hung or j ournaled in a slide, I, movable on a cross-bar, J, supported over the top plate, 0, in end brackets, K, attached to the frame of the laterally-movable paper-carriage. The hub of the cutter runs on and in contact with the top plate, so that when the slide by hand is moved along its supporting-bar a rotary movement will be imparted to the cutter, thus facilitating the operation of cutting the paper.

Back of the top plate and supported on centers f in the brackets K is a receiving or takeup shaft or mandrel, L, which is used when it is desired to take off the printed web of paper in roll form without dividing it into sheets. This shaft is conveniently made of a hollow metal shell, as indicated in Fig. 4, having a longitudinal slot in it for insertion of the front end of the paper. Intermittent rotary movement sufficient to take up the paper can be imparted to this take-up mandrel by any suitable means-in this instance by an elastic band or belt or cord, 9, running from a pulley, h, on the rotary chuck-center E to a like pulley, i, on the corresponding center (which like center E is a chuck-center) of the take-up mandrel L. The pulleys h i are graduated pulleys, so that the band 9 can be shifted thereon according as it may be required that mandrel L shall revolve faster or slower than the mandrel or shaft D, this being determined by relative diameters of the paper-rolls on D and L, respectively. Of course when the take-up roll L is used it will not ordinarily be necessary to use the cutter, and vice versa.

By winding up the printed web in roll itis put into a form in which it can be readily used--as, for instance, by lecturers or others. For example, a tablet, X, such as shown in Fig. 5, may be provided, adapted to stand in inclined position upon atable or the like, pro vided at each end with centers for supporting two mandrels like mandrel L, one at the top and one at the bottom of the tablet.

The full roll L can be removed from the typewriter and placed between the centers at the bottom of the tablet, and the end of the paper can then be passed down under the bottom of the tablet, up over its face, and then around its upper edge to the upper empty roll L, with which it should be engaged. Then by a handle affixed to that one of the centers of the upper roll (which is a chuck-center,) the roll can be revolved, and will thus be caused to draw off from the lower reel the printed web which passes up over the tablet.

To sever the paper it should by its free end be drawn taut over the top plate or cutter-bed, and while in such condition the cutter should be moved across it.

The arrangement of parts I have indicated is one made desirable by the particular form of type-writer selected to illustrate the manner in which my improvements can be carried into effect. Of course the arrangement will vary as may be found convenient or desirable, this being determined by the form of machine in connection with which my improvements are to be used.

Having now described my invention,what I claim is 1. The combination, with the paper-carriage and feed-rolls of a type-writer, of a cutter located on the carriage at a point beyond the feed-rolls, movable transversely of the paper, and arranged and adapted to sever or cut the same crosswise of its length, substantially as and for the purposes hereinbefore set forth.

2. The combination, with the paper-carriage and feed-rolls, of the slotted cutter-head or top plate and the sliding cutter, substantially as and for the purposes hereinbefore set forth.

3. The combination, with the paper-carriage and feed rolls, of a paper reel or roll from which a continuous web of paper passes to the feed-rolls, bearing for said paper reel or roll, and a paper-cutter located on the carriage at a point beyond the feed -rolls and movable transversely of the paper web, substantially as and for the purposes hereinbefore set forth.

4. The cylindrical shell A and feed-rolls B, in combination with the paper reel or roll supported in end bearings or centers in said shell, one of said bearings or centers being removable, so as to uncover the end of the shell, substantially as and for the purposes hereinbefore set forth.

5. The combination of the shell A, the feedrolls B, the paper reel or shaft D, the take-up roll L, the slotted top plate, 0, and the transversely-sliding cutter, these parts being arranged and operated substantially as and for the purposes hereinbefore set forth.

In testimony whereof Ihave hereunto set my hand this 26th day of February, A. D. 1887.

ANSON MILLS.
