B0.0KHOLDER..

i Application filed, June 24, 1921, Serial My invention relates to new and useful improvements in a book holder and more particularly to a device of this character adapted for a telephone book or other d1- rectory! to which, frequent reference is made.

The primary object 01'' the invention r esides in the construction of the holder 111 such a manner that it will normally hold the book in vertical position against a desk, wall, or other supporting object, but wh ch may be swung and raised so as to support the bookin open. horizontal position.

Another object consists in the provision of means for securely supporting the holder in raised position and for quickly releasing the supporting means to allow the holder to drop into its original or vertical position.

A further object resides in a novel form of wing for opening, closing and supporting thebook carried by the holder, said wings being detachable so that they may be removed when desired for shipping or for replacing should they become broken.

With the above and other objects in view,

which will appear as the description proceeds, my invention consists of the novel details of construction and arrangement of parts, described and illustrated; in the fol lowing specification and drawings, and while 1" have illustrated and described the preferred embodiments of the invention, it will be understood that such changes may be made as will fallrwithin the scope of the appended claims.

In the drawings:

Figure 1 is a side elevation.

Fig. 2 is a. tragmentalvertical' section, with parts shown in elevation.

Fig. 3 is a fragmental front view.

Fig. 1 is. a top plan. 1

Fig. 5 is affragmental rear view with parts shown in horizontal section.

.Fig. 6 is a horizontal section through the book rest with portions of the wings shown in plan.

"Fig. 7 is a horizontal section. through the book rest sl'iow'ing the operating lever for releasing the supporting member, and

Fig. 8 is a detail perspective, partly in section, showing the supporting means.

In the drawings, 1 indicates an arm having the vertically extendingv sleeve 2 formed at its outer end. lfhisarm is; adapted to be secured to a desk, wall or other suitable sup-.- port by means. of wood screws. or similar No 180,042, Renewed- January. 8, 1927.

fastening means and, as more clearly, shown in Figure 1, preferably is formed to extend at an angle so as to take up the least possible space. A frame is. pivotally connected' to the arm 1 by' means of the pin, 4, said pin having ared'uced portion 5adapted to extend through the sleeve 2. and a further reduced" portion 6- adapted to pass through an opening in the lower rearwardly extending arm 7 of the frame. A. thumb screw 8 has its threadedportion 9-extendin-g through an opening in the upper rearwardly extending arm 10 of the framemnd entering a recess formedin the upper end of the pin 1. By the construction described, it will be seen that the frame?) is carried by the arm 1 so as to freely swing horizontally and while 1' have shown the frame as formed of two substantially C-shaped portions, connected together, it will be understood that it i'i'iight equally as well be constructedin one piece.

A. support 11 is connected to the frame 3, by thepin 12, said support being mounted for horizontal swinging movement and for vertical adjustment. The pin. 12 passes through openings formed in the upper and lower forwardly extending arms 13 and 14: ot'the trame and lugs 15. formed on the rear ace; of the support 11. Vertically spaced pro ections 16 are formed on or secured to the rear face of the support 11, as more clearly shown in- Figures 1 and 2, of the drawings. These projections 16 are used for vertically adjusting the support 11 with respect to the frame Normally, both projections will be positioned between the

arms

13 and 14 of the frame, but if it is desired to raise the support, with its associated parts, the projections will be positioned as shown inFigs. 1 andv 2, with the upper projection; engaging the top of the arm 13, the lower projection limiting the movement of the support when the book-rest 21, to be later described, is raised. The raising of the support, 11 is sometimesnecessitated by unusuallythick desk tops and by providing; the projection 16,. allowing; the vertical adjust: ment of the support, theleaf supports, to be later described, will clear the topof the desk, when opened, allowing the bookto be swung around to the user without striking the desk. The horizontal swinging movement of the support is: limited by the end of the arm. 13 contacting with} the; rear face of the support. The support 11 is formed with the side flanges 17 and at the top the flanges have the forwardly extending portions 18. "Outwardly curved or flared lips 19 are formed on the upper edges of the portions 18 for a purpose to be later described. Pivotally connected to the portions 18, of the support 11, by means of a horizontally extending pin 20 is a book-rest 21 having the lower end rearwardly curved to provide the handle or gripping portion 22. The horizontal pivot pin 20allows the bookrest to be raised vertically "and to be extended in a horizontal position to support the book in a manner to belater described. A bar 23 is pivotally connected adjacent the lower end of the support 11 by the horizon.-

tally extending pin 24, the pivoted end of the said bar being received between the sides 7 17. Vl hen the book-rest is lowered .intovertical position the bar 28 will also assume a substantially vertical position as more clearly shown in Figures 1 and 2 of the drawings. 'Vertically spaced angle iron plates or-brackets 25-are secured to the rear face er the book-rest 21 and rotatably support, therebetween, a rod 26 having the notches 27 intermediate the ends thereof. The rod 26 is normally positioned, by the coiled spring 28, to have the notches 27 in position to be engaged by the lower edge 29 of the bar 23, or in, other words the notches will normally facetowards the rear. The coiled spring 28 surrounds the rod 26 adjacent the upper end and one end thereof is connected to the uppermost angle iron bracket 25 and the opposite end is connected to the rod so that when the rod is rotated by the lever .30, extending through the hori zontal slot 31in the book-rest 21, it will be placed under tension to return the rod to its original. position when the lever is released. Pivotally connected adjacent the lower end of the bar 23, by the pin 32 is the yoke which surrounds the 'rod'26 in such a manner that the edge 29 of the bar will contact with and ride on the rod. The edge of the bar is held tightly against the rod by theleaf spring 34 received between-the rod and face of the yoke as more clearly illustrated in Figs. '2 and 8. lVhen the yoke is slid upwardly on the rod the spring will cause the edge of the bar to engage the notches 27 and thereby hold the book-rest in an inclined or horizontal position.

A" red 35 is provided for connecting the book, not shown, to the book rest. The lower end of the rod is bent at right angles and is provided with an enlarged end 36 of greater diameter than c the opening 37 through which the right angle portion of the rod passes. The upper end of the rod is also bent at right angles and passes through the opening 38 and is screw threaded, as shown at 39, to receive the thumb nut 40, It will be understood that the rod 35 is vplaced be tween the leaves of the book and tightened by the thumb nut 40. The rod will be con nected to the book rest by first inserting. the threaded end 39 through the opening 37 and then through the opening 38.

A pair of vertically spaced eyes 41 are formed on or secured to each side edge of the book rest 21 for pivotally connecting the wings 42 to the book rest. The wings 42 are formed with the lower reduced extensions 43 adapted to, be received in the lowermost eyes 41 and the reduced extensions 44 adapted to be received in the uppermost eyes 41.' The upper ends of the extensions 44 are bent at an angle, as shown at 45, to engage behind the lips 19 as more clearly shown in Figures 1, 3 and .4 of the draw ings. The wings are swung by the angular extensions 45 engaging with thesaid lips as the book rest is raised and lowered and it will be understood that the wings engage the outer faces of the book. ,When the book rest is in a vertical position, the book will be held closed but when raised to horizontal position the wings will also assume a horizontal position and support the book in open position. Coiled springs 46 encircle the extensions 44 of the wings between the shoulders 47 and upper eyes'41 and these springs hold the wings in proper position with respect to the eyes, at the same time allowing the wingsto be disconnected when desired. Plates 48 are secured to'the rear edge of the wings and when the wings are in horizontal position will engage the edges of the book rest, as more particularly shown in Figures 3 and 6, and support the wings. Ears 49 are struck from the book rest, adjacent the rod end and engage the lower end of the book to help support the same. 7

From the above detail description it is thought that the construction and operation of my book holder will be clearly understood and it will be seen that I have provided a device, as previously stated, particularly adapted for normally holding; a boolrin vertical position against a desk, wall, or other support,l)ut which may be raised to open and support the book'in horizontal position forreference. The arm 1 extending at anangle, from the support, takes up little room and allows the frame 3 to be swung against the support with the book rest extending vertically, with the book closed, and parallel with the support. When it is desired to refer to the book the frame 3 is swung horizontally away from the support and the handle 22 of the book rest,'is grasped and the book rest raised vertically. The raising of the book rest will slidethe yoke 33 on the rod 26 and the edge 29 of the bar notches until the lever is swung horizontally to rotate the rod 26. The rotation of the rod 26 will disengage the edge 29, of the bar 23, from the notches 27 and allow the book rest to be swung downwardly into a vertical position. It will be noted that by having a plurality oi notches 27 the book rest may be supported in an inclined position or in a horizontal position. As the book rest is raised towards a horizontal position the wings 42 will swing open thereby allowing the book to open and be supported by the wings. As the book rest is lowered towards a vertical position the angular eX- tensions 4C5 engaging the curved or flared lips 19 will automatically swing the wings to a closed position thereby closing the book. The book is connected to the book rest by the rod which engages between the leaves of the book and is tightened by the thumb nut on the threaded portion 39. Should it be desired to entirely remove the rod 35 the thumb nut 4.0 is removed and the right angle threaded extension 39 is withdrawn through the opening 38. The rod may then be swung to be pushed through the lower opening 37. The enlarged end 86 on the lower end of the said rod 35 prevents this end from being withdrawn through the opening 87. When the wings are swung into open horizontal position the plates 48 will engage the under edge of the book rest and limit the swinging movement of the wings as well. as furnish a support there-for. Should it be desired, for any reason, to disconnect the wings the same may be raised against the tension of the springs l6. This will allow the rod extensions A3 to be removed from the lowermost eyes 41 and then the upper extensions 44. may be lowered and withdrawn from the uppermost eyes. The coiled springs 46 also tend to normally properly position the extensions in the eyes and prevent accidental displacement thereof. The projections 16 on the rear face of the support 11, being vertically spaced allow for a slight vertical adjustment of the support with respect to the frame 3.
