sPEcIFIcATIo'Nf'frming part of Letters Patent No. 753,490, dated March 1, 1904. Application iiled April 9, 1903. Serial No. 151,896. A (Nomodell) To a/ZZ whom t may con/cern:

Be it known that I, BRADBURY HILL, a citizen of the United States, residing at Osage, in the county of Mitchell and State of Iowa, have invented a new and useful Copy-Holder, of which the following is a specification.

The invention relates to improvements in copy-holders.

The object of the presentinventionis to improve the construction of copy-holders and to provide a simple, inexpensive, and eiiicient device designed to be applied to large books for enabling accurate copies andv extracts to be made from the same and adapted to conform to the conguration of and lie approximately fiat against a book-in which the leaves round up or bulge at the center.

A further object of the invention is to provide a device of this character adapted to be readily adjusted to suit books of different sizes and capable of enabling the indicator to be readily moved downward or advanced on its support and of effectually preventing the same from slipping accidentally, and thereby failing to indicate properly the part to be copied.

With these .and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes inthe form, proportions, size, and minor details of construc-` tion Within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. A

In the drawings, Figure 1 is a perspective view of a copy-holder constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view, the indicator-'arms being shown in plan view. Fig. 4L is a 'transverse sectional view illustrating .the manner of mounting the indicator on the supporting-rod.

Like numerals of reference indicate corresponding parts in all the figures of the drawings. I

l designates a rod forming a support for an adjustable indicator and provided at its lower end with a resilient hook 2, forming a clamping device and adapted to engage the bottom of a book at the center thereof. The rod or support is secured to the top of a book by an adjustable clamping device, consisting of a bar 3, centrally connected with the rod 1 and provided at its ends with rearwardlyprojecting hooks 4, adapted to engage several leaves of a book. The hooks 4t may be made of any desired size -to enable the requisite number Vof leaves tobe engaged, and the bar is provided with a centrally-arranged rearwardly-projecting resilient hook 5, adapted to engage the top of the book at the center thereof. -In practice the lower hook of the rod is first engaged with the bottom of a book, and the upper clamping device is then engaged with the top of the book and pressed downward or inward to clasp the book tightly, and the upper clamping device is secured in its adjustment by a clamping-screw 6, mounted in a threaded perforation of a casing or guide V7, having an aperture for the rod, which is preferably round. VThe rod may be constructed of metal or any other suitable material, and the lower resilient hook may be formed integral with the rod, as indicated in Fig. 2 of the drawings, or it may be constructed in any other desired manner, as will be readily understood. The upper clamping device may be constructed of metal or any other suitable material, and the central and end hooks may be applied to the bar, which forms the body portion of the upper clamping device, in any desired manner. The end hooks 4 are preferably integral with the bar, and

the central hook may be either formed integral with the bar or be constructed separatev therefrom, as desired. Any form of casing ,7 may be employed to form a guide for the upper clamping device.

The indicator, which may be constructed lof any suitable material, preferably consists of `a central section 8 and end sections 9, connected with the terminals of 'the centralV section by hinges 10 to permit 'the arms formed I IOO I sections is located adjacent to the support and approximately at a point where a book is liable to bulge or round up in order to cause the outer section to hug closely the book. The former is provided at its outer end with a weight 11. Any form of hinge joint or connection may be employed, and instead of providing separate hinges, as illustrated in the accompanying drawings, the eyes may be carried by the sections and be formed integral with the same.

The central section 8 of the indicator is provided with a casing 12, through which passes the rod 1, which forms a guide and which is engaged by a pair of spring-actuated clamping-levers 13, fulcrumed between their ends at the front of the casing 12 and provided with inner curved jaws 14. for engaging the rod 1 at opposite sides thereof. The terminals of the jaws are connected by a coiled spring 15, which holds the jaws firmly in engagement with the combined guide and supporting rod. The outer portions of the levers are shaped to form handles and are adapted to be compressed to distend the spring and open the jaws, to ypermit the indicator to slide freely on the rod. When the outer portions of the clamping-levers are released, the spring retracts and automatically carries the jaws into engagement with the rod, whereby the indicator is firmly clamped to the rod and is efyfectually prevented from accidentally slipping thereon. rlhe inner ends of the levers are perforated to receive the terminals of the coiled 'spring 15; but the latter may be connected with the levers in any other desired manner. The levers are preferably connected with the casing by a pivot 16, and they extend outward through a slot 17. The casing is provided at opposite sides with laterally-extending perforated ears 18 for the reception of fastening devices for securing the casing to the central section of the indicator; but the casing may be applied tothe said central section in any other desired manner.

I In order to enable the indicator to slide freely over the book to which the device is applied, the central section is provided with opposite antifriction devices, preferably consisting of rollers 19, mounted in suitable slots or openings and projecting from the inner or rear' face of the said section. The antifriction-rollers may be journaled on the central section in any suitable manner, and they enable the indicator to slide easily over the surfaces of the opposite pages of a book and prevent the indicator from binding or accidentally tearing or otherwise injuring the leaves. The present invention is designed especially for use in connection with large books containing public records and is adapted to be readily applied to books of different sizes, and indicators having arms of different lengths may be employed and can be quickly applied vto the combined guide and supporting rod.

Also a single indicator-arm may be employed, if desired.

The weights at the outer ends of the outer sections of the indicator prevent the ends of the latter from being lifted or moved away from the book to which the device is applied by any bulging or rounding of the book at the center. When the device is applied to books which are capable of opening out perfectly fiat, the indicator may be provided with a stif unyielding arm and the weights may be omitted. Also the indicator may be provided at each arm with a plurality of movably-connected sections to secure the desired iiexibili ty of the indicator and to enable the arms thereof to yield or bend to the desired extent.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A device of the class described having an adjustable indicator provided between its ends with a hinged joint, the hinged portion being arranged to swing toward and from a book, whereby the adjustable indicator is adapted to conform closely to the configuration of a book and to lie against the leaves when the same are rounded or bulged, substantially as described.
