COPY HOLDER FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 724,982, dated April 7, 1 903.

Application filed June 26,1902. Serial No. 113,309. (No model.)

To all whom it may concern.-

Be it known that I, FRANK E. WILLIAMSON, a citizen of the United States, and a resident of Glasco, Cloud county, Kansas, but temporarily residing at Washington, District of O0- lumbia, haveinventedanew and useful Copy- Holder for Type-Writers, of which the following is a specification.

My invention relates to copy-holders in which use is made of pointers or line'markers that are moved across the face of the copy; and it has for its object to produce copyholders of this character that shall be adapted to be used in connection with type-writers such as employ movable carriages and that are arranged to be operated automatically by the movements of the type-writer carriage.

The invention consists in means whereby this and other objects are attained, as will be hereinafter set forth.

In order that myinvention may be the better understood, I have in the accompanying drawings illustrated ,the preferred embodiment thereof without, however, wishing thereby to limit my invention to the precise construction and arrangement of parts shown.

In such drawings, Figure 1 is a front view of a copyholder embodying my invention, represented as being applied to a type-writer of a well-known make. Fig. 2 is a rear view of the holder, some of the parts being in a; different position from that represented in} Fig. 1. Fig. 3 is a detail view, enlarged, of the means forimparting motion to the pointer or marker.

justable contact-piece. Fig. 6 is a detail perspective view of the pointer or line-marker. Fig. 7 is a top plan view of the means for imparting motion to the cord to which the pointer is attached.

In the accompanying drawings, A represents the stationary frame portion of a typewriter, which may be of any usual or preferred construction, and B the movable carriage. The copy-holder is supported adjacent to one end of the type-writer, preferably near that end toward which the carriage B is moved when it is intended to commence the writing of a line. The holder may be supported in any desired manner; but I prefer to connect it directly with some of the Fig. 4 is a detail edge view of. Fig. 5 is an elevation of the ad stationary frame parts of the type-writer, as I thereby am enabled to insure the holder having a fixed position relative to the typewriter when it is set up for use.

The copy-holder consists of a supporting board or back 2. This may be of any preferred size, preferably being about that of a legal-cap sheet of paper, and it may be formed of any suitable material, either wood ormetal.

It is held in an n pright position by the brackets 3 and 4, to the outer ends of which the board is hinged, as indicated at 5. This hinging of the board to its supporting brackets or standards permits of a limited adjustment or change of the inclination of the board to suit the convenience of the user. -The upper bracket or supporting-standard3 is preferably formed of a pair of bars arranged to be clamped to parts of the stationary frame of the type-writer, while I prefer that the lower bracket or standard should be made of highlyelastic wire, the ends of which are formed into hooks 6, adapted to engage with suit-able stationary parts of the type-writer. I do not wish to be limited to these particular means for supporting the board or back 2; but they are well adapted for use in connection with a typewriter such as illustrated and permit of theholderbeing quickly applied to or removed from the type-writer, as may be required, and

at the same time support it firmly when. in use.

11 designates a pointer or line-marker in front of the board 2 and arranged to be moved across the same to indicate the line being copied. It is supported by a cord or other flexible device 12, mounted upon.

rollers

13 and 14, supported at the edge of the board and preferably near the top and bottom thereof, respectively. In order to move the cord,

and through it the pointer or marker, I carry the cord one or more times around a pulley or roller 15, which is arranged intermediate the

rollers

13 and 14 and preferably on the back side of the holder. The pulley 15 is formed with or has attached to it a ratchetwheel 16, with which there is adapted to engage a pawl 17, carried bya lever 18. The lever is preferablypivoted in the same frame that supports the pulley 15 and upon the same axis. It extends beyond the inner edge of the board 2 toward the type-writing ma chine and is so disposed that when the carriage of the type-writer is moved to the righthand positionthat is, the position to begin a new lineeither some part of the typewriter itself or an attachment secured thereto engages with the lever and moves it backward into the position indicated in Fig. 1. As the lever moves from the normal position, (indicated in Fig. 2,) where it is held by a supporting-piece 19,.to the forward position (indicatedin Fig. 1) the pawl 17 engages with the ratchet-wheel l6 and moves the cord, and with that the pointer.

The support 19 is so disposed as to hold the lever 18 at the proper inclined position to cause it to move in advance of the carriage when the latter or the contact part which it may carry comes into engagement therewith as it comes to its initial position. As the type-writer carriage moves in the other direction it gradually leaves the lever, which comes back to normal position by gravity.

Instead of having some portion of the typewriter carriage engage directly with the lever 18 I prefer to mount a contact-piece upon the carriage and to make this contact-piece adjustable, so that it will give a longer or shorter movement to the lever-arm 18, according to the position to which the contact-piece may be set.

20 indicates a holder which is arranged to be clamped to some suitable part of the movable type-writer carriage, such as to one of the end rails thereof. In this holder there is mounted the adj nstable contact-piece proper, which is designated 21 and consists of a plate or bar adapted to slide into and out of the holder 20.- One of its faces is ratcheted, and with such face there engages a spring pawl or dog 22. The ratchet-teeth 23 on the contact-piece 21 are preferably so constructed as to allow the latter to be freely pulled out, but to prevent its being moved in the opposite direction except when the spring-pawl is positively moved to free the contact-piece. It will be understood without further explanation that when the contact-piece is pulled out it will give to the lever 18 a longer movement than when it is further pushed into the holder and that the extent to which the pointer moves at each reciprocation of the type-writer carriage depends upon the amount of movement imparted to the lever 18. By these means the operator is relieved of the necessity of adjusting the pointer by hand, it being moved automatically a step at a time as the carriage is shifted in the usual work of typewriting. By adjusting the contact-piece in its holder 20 the operator can easily cause the pointer to move over the face of the copy at a speed which is approximately exactly that at which he is copying. If it should be found that the pointer is not moving at the proper speed to suit the work being done, but, as will often be the case, it moves temporarily too fast and then temporarily too slow, these slight inaccuracies can be easily corrected by adjusting the pointer by hand and again start- .ate itshould be normallybroken.

ing it at the proper point. In order to allow of this adjustment by hand either forward or backward, I prefer that the connection between the cord 12 and the means which actu- Thus when the lever 18 occupies its normal position (indicated in Figs. 2 and 3) the pawl is held out of engagement with the ratchet-wheel 16, so that the line-marker and the cord which operates it maybe moved freely either backward or forward, such movement causing the rotation of the wheel 15 and notbeing in any wise interfered with by the pawl and its carrying-lever. This I effect by arranging a stop 25 in the path of the pawl and in such a position relative thereto that the nose or engaging end of the pawl is held upward and out of engagement with the ratchet-teeth when the lever 18 occupies its normal position. As soon as the lever begins to move forward the pawl is carried out of engagement with this stop and then falls by gravity directly in engagement with the ratchet-wheel 16.

In order to hold the pointer down upon the copy, I provide its heel end-that is, the end which is connected with the cord 12-with a contact-piece adapted to bear against the adjacent edge of the board 2. This contactpiece may be formed of wire and made elastic. It is indicated in the drawings at 24.
