1 Claim. 1

This invention relates to an improved book rest and copy holder. In some respects it is an improvement in the structure shown by the prior Hancher Patent No. 2,192,574 of 1940, manufactured by the assignee of the present application. A line indicating device in this disclosure is a specifically new and useful device for use with copy holders generally but particularly useful for a simple copy holder of the Hancher type. The structure as a whole is adapted for low cost manufacture and for convenient handling by the user.

In the drawings:

Fig. 1 is a. perspective view of taken from the front;

Fig. 2 is a similar view taken from the back;

Fig. 3 shows construction detail of the line indicator; and

Fig. 4 is a sectional view showing the gear and handle mounting for the line indicator,

The main part of the holder, apart from the line indicating means, is generally like that of the said Hancher patent. These similar parts are the main rest plate H, the outwardly extending bottom ledge l2, the bead I3 to hold the pair of U-shaped holding members l4 slidably mounted in said bead so as to be independently adjustable longitudinally and laterally, the easel support I6 hinged to the back, and the pair of arms l8 and I3 pivoted to the upper portion of the back of plate I I, the extension pieces 20 slidably mounted on said arms, and the spring clips 2|, all for their known functions. The similarity of the main part, in the named details and their function, is clear on comparison with said Hancher patent.

The difierence in such details relates to the manufacture. For example in the new structure each leg ID is made of metal cut from the back on three sides of a rectangle to form a tongue. The tongue is then bent down in to the form of a leg 10 as shown. In a similar manner a tongue is cut out adjacent each upper corner of the back. Each tongue is bent over to form an eye 3 on the back. The single piece easel support or wire l6 has its ends bent to fit these two eyes 9 and form hinge pivots at those corners. These detail changes result in a lower cost of making the Hancher kind of copy holder and improve its appearance.

The line indicator for the copy holder will now be described. In its preferred form shown, it consists in a short bottom strip 30, slightly overlapping the underside of ledge 12 at one end, and. fastened there as by screws. At the other end of strip 30 rests an angle footing 3| bent out horizontally from vertical strip 32. A corthe structure responding upper bend 33 provides for a threaded rod 34 to be mounted vertically. The upper end of this rod is conveniently fastened for support by a metal screw 33' passing through bend 33. The

lower end is conveniently supported by passing through footing 3i and strip 33 and fastened with a nut all as indicated. The vertical strip 32 is additionally supported in its position by strip 39 welded on the back of the strip 32. The other end of strip 39 is overlapped on the back H and fastened there by metal screws. The threaded rod 34 is provided with a carrier made of a short cylinder 35 fitted to slide along or turn on the rod. This cylinder has a long slot, see Fig. 3, by which a gear 46 may engage the teeth of the rod. The cylinder is preferably made by bending sheet metal to just about fit around rod 32 like a looped strap l, for sliding movement of the loop, i.e. the cylinder 35. The ends of this strap form are brought together and welded. The slot is formed by forming a U-shaped end on the strap formation, as in Fig. 3. Then gear 36 may extend through the slot, the legs 2 may be welded to the overlying end, of the strap form. This end is extended as indicated beyond the legs 2. A bearing for the gear is made in the extended end of the strap I.

The gear 36 is preferably fastened to a hub on one side, see Fig. 4. To this hub is fastened a turning handle 31 for the gear. The hub has a pin 38, extending through the gear and beyond the other side, with a head on such pin. By heading over the pin on its outer end, it provides means for holding parts together with a coil spring 43 as described below. There is as shown, a straight edge or member 40 fastened by a screw onto the strap end. A convenient arrangement is indicated by the small strip 4|, see Fig. 2, placed on the back end of member 40, into which the screw is threaded. The other end of strip 4| has an opening through which the pin 38 of the gear handle passes, see Fig. 4. The pin extends far enough out from strip 4| for a little coiled spring 43 to be mounted on it. Then the head 42 is made at the outer end of the pin. This head is pushed against the spring 43 to compress it when the head is put on to hold the compression of the spring. Of course the gear handle is pressed oppositely in this assembly. The result is a friction mounting for the gear. This makes it hard enough for the gear to turn, so that it will not turn except when the handle 31 is used consciously for the purpose. Thus the straight edge or member 40 will rest at that elevation to which it is moved by turning the gear handle 31.

It will now be seen that the straight edge, used to underlie the line of the copy to which the eye wants to be directed, may be moved to position by turning the gear handle. Furthermore the straight edge may be swung 180 on or off the copy on back N. This swinging operation is provided for by the cylinder 35 turning on the rod While it is held to: a desired elevation'by engage-, ment of the gear-teeth with the thread, on the rod 34. When the thread is given a small pitch as indicated, 180 turning of the straight edge;

will not change its elevation enough tomatter; any. This structure makes an eificientlow-cost line indicating device for theacopyholdeit The line indicating devicec-mayrbe appliedrandf removed as a unit device to the copyxholder':

Sometimes it is desired to have,.a ,lineindicator..

and sometimes not, as the Work at the typewriter varies. When one is wanted it is very easily atitached by the metal screws indicated in Fig. 1. It goes on and off as aeunit.

It will be noted that the-devicemay, be used, as-a book rest, or as; a copy holder forlong sheets and with or without aline indicating and, easily adjustable straight edge; The combination isadapted for low cost manufacture, several; kinds of convenient use, and,consideredasawholeis quite simple in appearance-aswellasspecifically new and useful.
