CHARLES SPIRO, OF NEW YORK, N. Y.

COPY-HOLDER.

SPECIFICATION forming part of Letters Patent No. 532,346, dated January 8, 1895.

I Application filed January 24, 1894. Serial No. 497,921. (No model.)

To all whom, it may COM/0677b.

Be it known that 1, CHARLES SPIRO, a citizen of theUnited States, residing at New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Copy-Holders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and usefulimprovements in copy-holders and line indicators of that class in which the indica tor-arm or bar is given a step-by-step movement by means of a finger-piece actuating a rack-bar which is engaged by a pawl and a stop provided for adjustment to regulate the amount of movement of the indicator-arm or bar.

The present improvement has for its ob- 'jects among others to provide a simple and cheap device of this character having provision for ready connection with the frame of the machine or detachment therefrom, and for this purpose I form the frame of the holder with its side bars sufficiently resilient to enable the ends thereof to be sprung into openings in the sides of the base of the frame of the machine, the cross bar connecting the said side bars being so connected with one of the side bars as to allow of movement of the latter independent of the cross bar to distributethe yielding of the said side bar for a greater portion of its length instead of confin ing it between the end and the point of connection with the cross-bar. To this cross-bar and to the top bar of the frame of the holder is secured a plate which servesas a support novel construction of slidingblock to which the indicator-arm orbar is pivotally connected. This block consists of a strip of metal bent to embrace the side bar of theholderframe anda block is fitted between the extended ends thereof and then the block and extended ends of the metal strip are sawed out to form ears forthe pivotal support of the arm to which the indicator-bar is connected.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the let ters of reference marked thereon, form a part of thisspecification, and in which- Figure 1 is a front elevation of my improved copy-holder and line-indicatorshown in position upon the base of a type-writer, which latter is indicated by dotted lines. Fig. 2 is an edge view of the improvement as shown in Fig. 1. Fig. 3 is a vertical section taken on the line 3-3 of Fig. 1'. Fig. 4 is an enlarged sectional detail on the line 44 of Fig. 1,1ooking down. Fig. 5 is a perspective detail showing the block on the side bar of the holder.

Fig. 6 is a detail, and Fig. 7 a side elevation on a smaller scale, showing the holder in position.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the frame or body portion of the holder. It is formed preferably of a single piece of light material' with the two substantially parallel side bars a a, and connecting bar a at the top as seen in Fig. 1. The free ends of the side bars are bent at right angles to their length as seen at a and thence downward to form the arms a? the free ends of which extend inward as seen at a in Fig. 1 and may be and preferably are made round as seen at a. to engage in openings Z. in the base A of the machine as indicated by dotted lines in Fig. 1. 7

At a point between the upper and lower ends ofthe holder the side bars'thereof are connected by means of a cross-bar B which is preferably of sheet metal with its front edge turned up at right angles as seen at b and at one end formed or provided with a down- .w'ardly-eirtending lug b which is secured to IOC to the lug b so as to lie parallel with the in- 1 ner face of the side bar a, as seen in Figs. 1

and 2.

This lugb has an opening through which loosely passes a screw 13 into the side bar a as seen in Fig. 1. The screw has by preference a head with a flat under face as seen best in Fig. 1 to limit the inward movement of the lug or to prevent separation of the parts. It will thus'be seen how the side bar will have a limited freedom of movement to and from the end of the cross-bar sufficientto enable the side bar to spring sufficiently to enable the side bars to be separated to spring the lower ends into the openings in the base or to remove the holder from the machine when desired.

0 is a plate held at its lower end in any suitable manner to the cross-bar B, as for instance by having a flange c at its lower end as seen in Fig. 3 held to the cross-bar by screws or rivets c as shown in Fig. 3. The upper end of this plate is flanged as seen at c and held to the upper connecting bar 0. of the frame as by screws 0 as seen in Figs. 1 and 3.

D is an elastic band passed around the side bar a and around the plate 0, serving as a yielding connection between these parts to allow the side bar to spring when necessary and serving also as a means for holding the copy upon the plate 0, as will be readily understood.

Fitted to slide upon the side bar a of the holder-frame'is a block which I construct as follows: I take a strip of sheet metal E and bend it to embrace three sides of the side bar with the ends thereof extended beyond the other side as seen best in Fig. 5 to form the arms e,and then between the said arms-Ifitand secure in any suitable way, as by brazing or soldering, a block or piece E and then saw transversely through the said block and arms .to form the opening e, making the ears e which are perforated vertically as seen at e and'between whichears is pivoted as upon a vertical pivot f held in the said ears, the arm F the other end of which is pivotally connected as at f with the indicator-arm or bar F which is arranged to bear upon the copy which is designed to be held upon the plate 0.

G is a bar provided upon one-edge with teeth 9 and, at its lower end, having a fingerpiece gas seen in Fig. 1. This bar is provided with the longitudinal slots 9 and g in the former of which works a pin or screw G held in a lug A of the frame of the holder, and in the latter works a thumb screw G screwed into a lug a on the holder-frame as seen in Fig. 1. A spring 11 connects this lug or any part of the frame,with a projection or hook h on the lower end of the bar G, as seen in Fig. 1 and serves to draw the bar upward when pressure is released from the finger-- piece g.

I is a stop mounted on the side bar a and adjustable thereon by means of a set screw 1 as seen best in Fig. 2. It is designed to be engaged by the hook or projection h and is ad justable to vary the movement of the rackbar G to regulate the distance the indicatorarm or bar shall move, according to the space between the lines of the copy.

K is a pawl pivotally mounted upon the side of one of the ears 6 of the block E as 'seen best in Figs. 2 and 4 and adapted to engage the rack teeth of the bar G. The acting face of this-pawl is curved and. is provided with a plurality of small teeth as seen in Fig. 2 so as to the better catch into the teeth of the rackbar and insure the stopping of the bar at the desired place and also to enable me to obtain a greater or less variation in the distance that the indicator-bar or arm shall move. I

The operation will be readily understood from the foregoing description when taken in connection with the annexed drawings, and a further detailed description thereof is not deemed necessary.

Modifications in details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages. For instance, in Fig. 2 the stop which serves to limit and regulate the movement of the bar G is shown as a slide adjustable upon the side-ba-r-of the frame, but this requires more accuracy of adjustment than most operators are apt to give it. I therefore prefer the device shown in Fig. 1 and in enlarged detail in Fig. 6, which consists of a cam plateL preferably of spring material having the eccentric Zonone edge and a series of holesZ on the other arranged upon the arc of a circle. This plate is mounted upon a pivot l on the side-bar a of the holder. This plate is held in its adjusted position by means of a stud or tooth Z projecting from the side-bar and adapted to engage any one of the holes of the plate. This plate is arranged in the path of the projection h on the bar G as seen in Fig. 1 and the movement of the said bar is limited by the engagement of its projection with the cam surface of the plate. For instance, if the plate is set wit-h the stud or tooth" tooth at each downward movement of the bar G. If the eccentric is set so that the stud or tooth will engage the second opening it will allow the depression of the rack two teeth, and so on. The plate is of sufficiently resilient material to allow of its being moved from one position to the other by simply turning it on its pivot.

One of the important advantages resulting from my construction of holder and its mode of attachment is that it may be so placed upon the machine that the copy held by it is in front of the operator so that a slight elevation of the eyes reaches it without changing the position I to In Fig. 7 I have illustrated on a small scale the holder in the position it occupies ona machine.

What I claim as new is 1. A copy-holder having its side-bars of resilient material and connected by a cross-bar having loose connection with one of the sidebars, as set forth.

2. A copy-holder having its side-bars connected by a cross-bar having loose connection with one of said side bars, and a plate mounted on the holder-frame and connected yieldingly with the side bar to which the cross-bar is connected by the loose connection, substantially as specified.

3. The combination with the holder-frame having its side bars connected by a cross-bar having a loose connection with one of the said bars, of a plate secured to said cross-bar and to the cross bar of the frame, and an elastic band passed around said side-bar and over 7 one edge of said plate, substantially as specified.

4. The combination with a side-bar of the holder-frame, of a strip embracing the sidebar upon three sides and a block held between the parallel sides thereof and cut away to form ears for the pivotal support of another part, as set forth.

5. The combination with a side-bar of the holder-frame, of a metal strip embracing said side-bar upon three sides with its ends extended beyond the other side and substantially parallel, and a block fitted between said ends with a recess formed in said block and ends and the block perforated vertically, as set forth.

6. The combination with the frame with spring side portions and a connecting crossbar having loose connection with one of the side portions, of a slide mounted on the other I side portion, an indicator-arm or bar carried by an arm pivotally mounted on said slide, and means for giving said arm a step by step movement, as set forth.

7. The combination with the holder-frame and the slide mounted thereon and carrying an indicator-arm, of a pawl mounted on said slide, a rack-bar slidingly mounted on the frame, and a spring connected at one end to a fixed part and at the other end to a projection on said bar which serves also as a stop to limit the movement of the bar and a cam stop on one of the side bars, as set forth.

8. The combination with the holder frame havinga lateral pin and a movably mounted rack bar, of a fiat plate of spring material piv-
