COPY-HOLDER FOR TYPE-WRITING M ACHINES.

SPECIFICATION forming part of Letters Patent No. 359,466, dated March 15, 1887.

Application tiled November 17, 1886. Serial No. 210,173. (No model.)

To aZZ whom it may concern:

Be it known that l, ALLEN S. PATTISON, of Cambridge, in the county of Dorchester and State of Maryland,- have invented certain new and useful Improvements in Copy-Holders for Type-\Vriting Machines; and 1 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 pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in copy-holders for type-writing machines, and is intended as an improvement upon a patent granted to me May 25, 1886, hearing No. 342,707, said improvements consistingin,first, the combination, with the carriage of a type writing machine provided with ears, projections, or sockets, of a copyholder having vertical standards which are secured thereto. The object of this partof my invention isito cheapen the construction of a copy-holder, which is adapted to be secured to the carriage of a type-writing machine, bycasting upon the carriage thereof ears, projections, or sockets, which will receive the vertical standards of said holder, and thus do away with a clamp or other expensive means for securing the holder thereto.

It consists in, second, a copy-holder having vertical standards which have formed upon their upper ends projections having horizontal slots for the journals of the front roller to move freely therein,and a stationary roller journaled in their upper ends, with which the front roller comes in contact, and springs for forcing the front roller in contact with the rear one when left free to move; third,a copy-holder having a stationary roller journaled therein and a movable roller journaled in a slot, so that the movable roller can be made to come in contact with the stationary roller, or be separated'therefrom,alever or levers for separating the two rollers, and a spring or springs for forcing the movable roller in contact with the stationary one; fourth, a copy-holder provided with a means for holding a sheet of paper, flexible book, or other similar matter, of a rod, or other equivalent means, which is placed in such relation to the two rollers as to prevent the paper from falling forward and hiding the matter which is exposed tothe view of the operator; fifth, a copy-holder provided with vertical standards, having rollers journaled in their upper ends for holding a book or sheet of paper, the shaft of one ofthe rollers extending through the standards a suitable distance, and having fixed thereon at its outer end a ratchet-wheel, a disk carrying a pawl, a string,wire, or cord for causing the disk to re volve, and a spring for returning the disk to position; sixth, a copy-holder provided with vertical standards having rollers journaled in their upper ends, the shaft of one of the rollers extending through the standard a suitable distance, and having a ratchet-wheel fixed thereon at its outer end, a plate carrying a pawl for engaging said ratchetwheel, ashoulde'r formed upon the plate or pin for preventing the pawl from being thrown out of contact with the ratchet, a cord, wire, or chain for operating the plate, and a spring for returning the plate to position; seventh, a copy-holder having vertical standards, rollers journaled in their upper ends, a mechanism, substantially as shown,for causing them to revolve by means of-a cord, wire, or chain attached to an operating lever or rod, which is provided with a stop for limiting its movement; eighth, in a copy-holder having vertical standards, the

rollers journaled in their upper ends, the

springs for holding the rollers in contact,

and which extend upward parallel with the 7 standards, and'a guide attached to the springs or marking the line of reading; ninth, in a copy-holder having vertical standards carrying rollers at their upper ends, springs for keeping said rollers in contact and which extend upward parallel with the standards, brackets for supporting a wire or cord which marks the line of reading, said brackets forming a spring, so that the tension of the wire 'or cord which connects them will not bind the levers for operating the front roller, said brackets being adjustable in relation to the front roller, so as to regulate the amount of matter exposed between the guide and roller, and a mechanism for operating the rollers; tenth, the combination, with the carriage of a type-writing machine, of a copyholder having vertical standards, a support pivoted between the two standards for guiding the sheet which is placed in the holder, a fordescribed hereinafter.

wardly-extending rod for guiding the paper which is being printed upon, said rod pivoted to the support and adapted to engage a notch formed in the flange of the support when extending over the roller of the type-writing machine, and to turn back under the support to allow the holder to be folded down upon the carriage when the cover is placed thereon; eleventh, a copy-holder having vertical stand ards carrying rollers at their upper ends, said standards being jointed, bands which pass over thejointed ends of the standards and hold them in a vertical position, and a spring for forcing the bands over the ends of the lower standards when theholder is raised in an upright position; twelfth, a copy-holder having vertical standards provided with horizontal slots in their upper ends, and a recess or slot extending at an angle'to the horizontal slot, at fixed roller, a movable roller which is adapted to be held in contact with the fixed roller by means of springs, and when drawn forward for the purpose of inserting paper between the two rollers drops in the recess and is held separated from the fixed roller, all of which will be more fully The objects of these parts of my invention are to provide a copyholder which is adapted to be secured to the carriage of atype-writing machine so as to have the matter being copied from directly in front of the operator, at a convenient distance there from to be easily operates, to operate the matter being copied from the front of the machine, regulate the distance that the paper placed between the rollers shall move at each manipulation of the operating-rod, providing an easy, convenient, and simple means for separating the rollers and locking them in this position while the paper is placed between them, and to provide a holder which can be folded down upon the carriage so closely that the cover can be placed thereon and carried with the machine and ready for use by simply raising it into an upright position over the carriage of the type-writer.

Figure l is a perspective of a machine embodying my invention. Fig. 2 isa side elevation showing the springs forforeing the bands over the jointed ends of the standards. Fig. 3 is an enlarged detail view of the mechanism for rotating the rear roller.

The carriage of the type-writing machine, as here shown, is provided with a lug or projection to which the vertical standards of the holder are secured. By thus providing the carriage with these projections, ears, or sockets, which willpreferabl y be cast as an integral part thereof, the clamp shown in my patent above referred to is done away with and the cost of the holder greatly reduced. Connect i'ng the standards 0 in this manner, all that portion of the holder above the projection can be folded down closely upon the carriage of the typewriter and the cover of the machine placed thereon. The standards 0 are held in an upright position by any suitable mechanical means. As here shown, a band, D, is

placed around the upper end of the standard B and the lower end of the standard 0 for the purpose of supporting the holder in an upright position. The upper end of the projection B is preferably made wedge-shaped, as shown, and the band D correspondingly wedge-shaped, so that it will bind the standard and the projection when forced downward and allow them no lateral play. One of the projections, preferably the one on the right of the carriage, is provided with a suitable hole, E, for the rod F to slide back and forth in, and a guide, G, for the cord, wire, or chain H to pass through, and then be secured atits lower end to the rod F. The rod F has a circle, formed as shown at l, which forms a convenient fastening for the string and as a stop for the rod, and its outerend is formed into a circle of suitable size for the finger. The rod will be made of a length sufiicient to project over the keys in a convenient position for the easy operation of it by the operator.

It will be readily understood that where the carriage is provided with a socket the standards B C may be made of one piece of metal, and the pivot and bandbedoneaway with and the construction of theholder somewhat cheapened. This is not preferable, however, for it would necessitate the detaching of the holder from the machine each time that the cover is placed thereon.

By means of the construction shown in Fig. 1 the holder need never be detached from the machine when it has once been placed in position thereon.

A support, J, is pivoted between the two standards 0, which form the upper framing of the machine, and projects rearwardly a suitable distance, for the purpose of supporting and guiding the book, sheet of paper, or other matter placed between the rollers, free from the framing of the machine as the carriage moves back and forth over the framing of the type-writer. The support is held in ahorizontal position by means of a pin or projection upon one or both of the standards 0, which extends inward and under the support at a point in rear of its pivot, and hence cannot turn downward upon its journals when the weight of the book is upon it, but has a free upward movement forthe purpose of folding. As this support is made of thin sheet metal, in order to give it sufficient strength to support the matter resting upon it without sagging at the center its inner edge is turned at right angles, as shown. Iivoted to this support is a forwardly-projecting rod, K, provided for the purpose of guiding the paper which is being printed upon under the support and out over the rear of the carriage.

A recess, L, is made in the downwardlyprojecting flange of the support for the pur pose of holding the rod K in its proper position over the roller of the type-writer. The rod is given an upward bend, which gives it sufficient spring to catch it in the recess in the flange, and thus form a stop forit. Were not IIO coming loose from use, when the carriage was raised in an upright position, would fall under the holder. The rod is pivoted for the purpose of turning under the support when the holder is folded down upon the carriage of the typewriter, and to be turned out of the way when paper is being inserted in the typewriter to be printed upon. support J, as shown, and pivoting the guiding-rod K, the support and the rod can be folded so as not to be in the way when it is desired to place the cover upon the machine and for conveniencein transportation, as they both fold closely to the upper framing of the machine, and will thus form a flat package.

Journaled in the upper ends of the standards C is the roller Z,which has one end of its shaftto extend beyond the standard sufficiently far to have the operating plate or lever M, carrying-pawl N, spring P, and the ratchetwheel 0 placed thereon, as shown. The ratchet-wheel-is rigidly secured to the shaft, and when made to revolve carries the roller with it. The plate or lever M freely revolves around the shaft, and is returned to position by means of the spring P after having been operated by means of the rod F and the cord or wire H. The pawl N engages the ratchet'wheel by its own gravity, and hencea spring for this purpose is unnecessary. The plate M is wheelby means of the spring P, which is 0011- stantly exerting a pressure in this direction, as well as a tension'for imparting a rotary motion to the plate, and thus return it to position after it has been partially or wholly revol vcd, for the purpose of turning the roller and causing the paper between the two rollers to pass upward. The'plate M is made sufficiently thick to admit of the cord being wrapped one or more times around it, and by this means the roller can be given a full revolution, if desired. If the operating-rod is allowed to fly suddenly back by the tension of the spring P, the plate M is suddenly stopped when the circle of the operating-rod reaches the projection or ear on the carriage, and the pawl, from the momentum given it, hasa tendency to fly backward and out of contact with the ratchet-wheel. For the purpose of preventing this,a lug is formed on the plate M, as shown, and thus holds it in contact with the ratchetwheel at all times.

In order to limit the movement of the roller to any desired portion of a revolution, so that the paper placed between the rollers can be revolved one or more times, the rod F may.

be provided with a series of holes, as shown, and a pin passed through any one of the holes. By this means the movement of the rod can be limited, and consequently the roller limited in its revolution each time the rod is manipulated.

The standards 0 have the horizontal projections R, in which is formed'a slot, as shown,

By journaling the held in contact with the ratchet for the shaft or journals of the front roller to freely slide back and forth in and to freely revolve when in contact with the rear roller. The front end of this slot is extended at an angle to the horizontal portion, so as to form a stop for the roller when pulled forward.

hen it is desired to place a book, sheet of paper, or other matter to be copied between the rollers, the front roller is pulled forward and allowed to drop into the downwardlyprojecting slot or cavity S, where it is held until the matter to be placed between the rollers is properly adjusted, when a slight upward movement of the roller by a pressure upon its under sidewill allow it to be forced against the rear roller by means of the springs. The springs have their lower ends rigidly secured to the standards 0 in any suitable manner, and their outer free ends to bear against the projecting ends of the shaft of the forward roller, as shown and keep the front roller constantly in contact with the rear one. The two rollers will be covered with rubber tubing, so that sufficient friction will be brought upon the matter placed between them to insure its upward movement when the rear roller is made to revolve by operating the rod F through the mechanism above described.

As here shown, springs formed of wire are used for keeping the front roller in contact with the rear one; but, if preferred, they may be held together by rubber bands, as shown in Fig. 2. In this case the guide U will slide upon the standard 0 in any suitable manner.

The leversV are pivoted 'to the front of the projections at any suitable point, and are so shaped that when brought forward th y will force the journals of the front roller down into the downwardly-extendingportionsofthehorizontal slots, where it is held until it is forced upward and out of the slot, when the springs instantly force it in contact with the rear roller. Thelevers are provided with cams at their pivoted ends, as shown, for the purpose of forcing the journals of the front roller up ward and out of the downwardly-projecting portion of the slot after it has been brought forward. It will be seen that by raising the levers upward the cams will force the roller from the downwardly-projecling slot and allow it to be carried by the tension of the springs in contact with the rear roller. The levers are preferably formed from a single piece, as shown in Fig. 1, and extend across the holder immediately above the rollers; but,

if preferred,they may be connected by a piece of wood and secured by means of a screw, as

shown in Figs. 2 and 3.

to' accomplish this the levers must be pivoted at a pointjust in front of the horizontal slot, and when brought forward cause the journals of the roller to enter the cavity XV, so that the tension of the springs is pulling in a line with In order the pivot of the lever, and hence cannot force l tal to a vertical position, the bands will be the journals out of the cavity and the levers back to the position shown in dotted lines. I do not limit myself toanyparticularconstruction of the levers, however, for the roller can be operated by levers of variousconstructions and the desired result accomplished.

In case the levers V are not used to operate the .t'rontrollers, thejournals of the roller will be extended beyond the outer side of the slot a suitable distance for the purpose of forming a hold for the fingers, by means of which it is brought forward when paper is to be placed between the two rollers, and held in this sepa rated position by falling in the downwardly projecting slot.

Sliding upon the springs T are the two wire brackets U, which have one end wrapped around the springs a number of times. in order to cause sullicient friction to hold them in any position into which they may be adjusted 1 The other ends in relation to the front roller. are bent at right angles to the springs and then upward a suitable distance, and these upi'orced down around the standards and pro jections without being placed there by hand. By this means the holder is ready for operation in a momentafterthc cover islii'ted from the type-writer.

It is found that the matter placed between the rollers has a tendency to hang forward, and more especially when the carriage of the machine is brought from a vertical to a horizontal position by the momentum given it by the movement of the carriage. "iVhen thepaper hangs forward, if thereis much ofitabove the rollers it hides from the view of the operator the matter exposed between the front roller and the gage or guide U. In order to avoid this annoyance, the upper ends of the i levers are made to extend a suitable distance 1 above the top of the rollers and across the wardiy-projectiug ends formed into hooks, as shown, for the purpose of securing a string or wire to them. These brackets and the string or wire connecting them are provided for the purpose of forming a guide to mark the line 1 of reading and to prevent the springs T from slipping off the ends of the roller. as they would otherwise be liable to do. By having the inner ends of these brackets to project from the springs the tension of the spring or i in Fig. 1, willdo.

wire connecting them will not bind the springs t T against the lovers and cause them to move stiff, and will move upward in close proximitv to the front roller. It these ends were not thus shaped and made to extend straight.

across, the distance between the guide and the front roller would be limited to that point where the guide would come in contact with i the under edge of the projections R. if desired, however, it is apparent that a single piece of wire maybe used and bent in this f shape, having its ends wrapped a number of,

times around the springs T.

As here shown, the front roller is made much l smaller than the rear one, so that it will not cover up any more of the matter being copied from than is real ly necessary. \Vere this roller made of the same size as the rearone it would reach down upon the sheet placed between the two rollers so far as to cover up the first line of writing or printing it" the writing is near the top of the sheet or book. The rear one is made larger for the purpose of taking a better Y hold upon the paper and to cause the paper to move a greater distance with a portion of a comes in contact, and springs for forcing the Fig. 2, and in this case, when the upper perholder, as shown. This portion, which extends across just over the rollers, as well as forming a handle for operating the levers, will prevent the paper from falling forward, as above described.

In case the levers are not used for operating the roller, the springs T may be formed of a single piece, as shown in dotted lines in Fig. 3, or have their upper ends connected together in any suitable manner, and will thus prevent the paper from falling forward in the same manner that the handle of the levers, as shown if preferred, the standards C could be extended upward a suitable distance and a wire or other device secured between their upperends, over the rollers. Thus it will be seen that this result may be accomplished in various ways, and hence I do not limit myself to any particular construction for preventing the paper from falling forward.

The holder is given a slight lean from the front of the machine, as shown more plainly in Fig. 2, for it is found to be a great advantage, inasmuch as it holds the paper in a better position to be read from.
