My present invention relates to improvements in book holders or copy boards,- and especially thoseof the kin'dnsed in conjunction with or as a part ofplwtographicapparatus employed for the purpose of producan'd the-'like- 1 In using such book holders or copy boards, it becomes necessary. attimes, to turn =-o r partially rotate the book, document or 'the like being photographed, in order that printing or writing which 'extends lengthwise or vertically on apage, instead 0t extending across the page, as usual, may i'n' the photographic copy of such page, "extend across th page. Where, as is usual, the book holder is arran ed immediately infrontfof the legs of the ta le which supports the photographic appar'atus,; it has "been impossible to turn or rotate the book holdertas its'corners would strikeagainst suchlegs. Consequentlyfithas heretofore been necessary i to remove the book or copy-i'from the holder and to replace it after turning, and then to restore the book or copy to its former position, these operations, however, being inconvenient and involving the loss of much time.

The primary object of this invention isito provide means which enables the bookholder or copy board to be easily and quickly turned from its normal or usual position to a position at a right angle thereto, and restored to its initial or normal position, whereby the reading or other matter which may be arranged in one way upon the original book or copy may be arranged in a'ditferent way in the reproduction or copy thereof, such means insuring the correct centering of the book or copy in front of the photographic lens when the hook holder is set in either of its positions, and it guiding the book holder while being turned from one position to the other so that the operation is facilitated and striking of the corners of the bookholder against the adjacent legs of the table is avoided.

To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts, all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

7 The present invention"fisraipplicable, generally,'to .book holdersand analogous devices ad aptedto'be employed generally for the purpose of holding orsupporting a book or the like normally in a given position and where it is desirable to turn or rotate the book or the like angularly so that the reading or other matter thereof may appear at a different an glc. The invention is particularly applicable to photographic copying machines of the class employed for-the purpose of making photographic reproductions of the pages of books, documents and the like, it enabling the reading or other matter contained in the book or original to be re-arranged in the photo graphic copy thereof so that it may appear in the desired way in the copy. More particularly, the invention enables a book undergo- I the page. The preferred embodiment of the invention is shown in the. accompanying drawings and will be hereinafter described in detail. It is to be understood, however, that the invention is not restricted to the precise construction shown, as etpiivalent c nstructions are contemplated, and such will be included within the scope of the claims.

In the present in:. tance,1designatesthe forward end of the table which supports a photographic copying machine 2 which may be of any suitable type employing a photographic lens and prism unit 3 which receives the light rays from a book or object supported beneath it and projects such rays onto a photographic strip or other sensitized medium contained within the machine, the construction and mode of operation of machines of this class being well known in the art. The book or other object to be photographed is conveniently supported in a horizontal position beneath the lens and prism unit by a plate or board 4 and this board is usually supported by and adjustable vertically on guides 5 which are attached to the forward side of the legs 6 of the table, ascrew 7 serving to adjust the said board and to support it in its different adjusted positions. In making photographic copies of books, it is usual to employ a book holder 8 which may consist generally of a rectangular casing which is preferably oblong so that it may accommodate to the best advantage books of various sizes and shapes. The top of the book holder, preferably has a glass or transparent panel 9 adapted to bear against the pages ofan open book, thus positioning the pages correctly in the plane for which the photographic machine has been focused, and this glass panel may be fitted in a frame which is hinged at 10 to one side of the casing so that it may be readily opened to permit insertion or removal of the hook or turning of the pages thereof, catches 11 serving, to hold the glass panel in closed position.

' The book designated B may be supported within the book holder by boards 12, and in order to compensate for differences in the thickness of the two sides of an open book. these boards may he supported by springs 13 which rest against the bottom of the book holder and support the boards 12 therein. A handle '14 is preferably provided at the front of the book holder to facilitate its manipulation. Book holders of differentconstructions may be used, the book holder shown and described above being an example of one suitable for use in carrying out the invention.

According to the present. invention, the hook holder is mounted on the board or support 4 so that it may swivel or rotate in a plane parallel with its top surface, itis guided during its rotating movements so that the corners of the book holder will not strike the table legs or the guides 5 thereon, and furthermore, the book holder is properly centered in each of the positions into which it may be turned. Preferably, and as shown in the present instance, the bottom or under side of the book holder has a baseor disk-like member 15 secured thereto and the board 4 is provided with a pivot 16 preferably a bolt having a clamping nut 17 threaded thereon and bearing against the under side of the said board. This pivot or boltprojects upwardly through the board and through the cam slot 18 which is formed in the bottom of the base or member 1, the upper end of the pivot or bolt being headed as shown. The upper or headed end of the'pivot or bolt, when the latter is unclamped by loosening of the nut 17, is movable freely in the cam slot 18 incident to shifting of the book holder on the board, but when the pivot or bolt is clamped by tightening of the nut 17, the base or member 1 attached to the book holder will be drawn down against the board 4, thus securing the book holder immovably thereon. The base or disk-like member 1 is fixed to the under side of the book holder centrally with respect to the width and length of the book holder, and one end 18 of the cam slot terminal is located at this central point while the other end 18 of the cam slot is offset relatively to the end 18 in a direction longitudinally of the longer dimension of the book holder and for a dista nee equal to half the difference between the diagonal dimension and the short dimension or width of the book holder." I

The oblong rectangular hook holder is adapted to occupy either of two positions; that is, either the position shown in Figure 1 and illustrated by the-full lines in Figures 2 and 3, in which case, its longer dimension is arranged transversely of the photographic machine, or a position at right angles thereto as indicated by the dotted lines in Figures 2 and 3, in which position the longer dimcnsi on of the book holder is arranged longitudinally of the machine. Mica-us is preferably provided for registering and yieldingly retaining the book holder in each of these positions. Preferably, and as shown in the present instance, such means cou'iprises a pin or plunger 19 which works vertically through an aperture in the board 4 and is normally and yieldiugly pressed upwardly by a spring 20 which may be attached to the under side of the board 4, as shown in Figure 6. The base or member 15 is provided with apertures '21 and 22 which are suitably arranged therein so that when the book holder occupies the normal position shown in Figure 1 and by the full lines in Figures 2 and. 3, the pin or plunger 19 will engage in the aperture 21, thereby holding the hook holder in such position, and when the. book holder occupies its turned position, as indicated by the dotted lines in Figures 2 and 3, the pin or plunger 19 will register with and project into the aperture 22, thereby retaining the book holder'in such position. The posi tions occupied by the base or member 15 when the book holder occupies its normal and turned positions respectively, is indicated by the full and dotted lines in Figure 5.

The mode of operation is as follows: Normally the book holder will occupy the position shown in Figure 1 and by the full lines in Figures 2 and 3, its longer dimension being then arranged transversely of the machine. When it is desired to turn or rotate the book holder so that a page of the book being photographed having printed or other matter thereon reading vertically of the page may be reproduced in the photographic copy so that such matter in the reproduction reads normally or across the page, or for other causes, the clamping nut 17 is loosened, the copy holder is grasped by the hands of the operator and is first pulled upwardly, this operation disengaging the pin or plunger 19 from the aperture 21, thus releasing the book holder for rotation, and the book holder can then he rotated by pulling it forward, in consequence of which the pivot or bolt 16 travelling in the cam slot 18 will cause the book holder to shift laterally relatively to the board 4 until the peak 18 of the cam slot is reached, whereupon the book holder is rotated in the proper direction and finally pushed back toward the table legs or guides 5 until the centering or locating pin 19enters the aperture 22. YVhen the book holder comes to rest-,as the result of this operation, its longitudinal dimension will be arranged longitudinally of the machine. one of its ends being adjacent to the guides 5, and in the position previously occupied by a longitudinal side of the book holder. The book holder is restored to its former or normal position by repeating the operation just described except that when the pivot 16 reaches the. peak 18 of the cam slot, the book holder is swung or turned in the reverse direction.

During the shifting of the book holder from its normal. to its turned position, and vice versa, the curve in the cam slot in cooperation with the pivot 16 will insure forward movement of the book holder which will be sullicient to cause the corner of the hook holder to clear the table leg or guide which it passes during this turning movement, and the ends of terminals of the cam slot in cooperation with the pivot 16, will bring the book holder to rest, at the end of its shifting or turning movement in either direction, when such turning or shifting movement has been completed, the center of the long and short dimensions of the book holder. in either of the two positions occupied thereby, being centered laterally beneath the lens and prism unit 3.
