Aliplication filed December 28, 1927. Serial No. 248,077. I

One of the important objects of the present invention is to provide a book holder wherein means is associated with the holder whereby to permit the same to be adjusted in various directions.

A still further object is to rovide a 001-.

lapsible book holder that can e readily and easily attached or detached with respect to one of he. bed posts, the book holder being readily collapsed and disposed adjacent the bed post when not in use, and being readily extendedfor use, means being provided for 0 bracing the extensible means.

A still further object is to provide a collapsible book holder of the above mentionedcharacter which is simple in construction, in-

' expensive, strong and durable and further well adapted to the purpose for which it is v her objects and advantages of the invention will become apparent from the followin description when taken in connection wit drawing. X In the accompanying drawing wherein like i i reference characters indicate corresponding Figure -1 1s a perspective view of the book holder embodyingmy invention showing the same in itsexten a bed post, and

parts'throu bout the severalviews:

2 is an elevational view of the same".

. igure frame of the book holder showing the supplemental frame attached thereto. In the drawing wherein forthe purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a vertically disposed plate-like bracket, the same being provided with thebed post engaging

members

2 and 3, respectively. Y These bed post engaging members are referably covered with rubber tubing or t e like to prevent'marring of the bed post and the manner in" whch these elements engageed position and attached-to around the bed post is clearly shown in Fig ure 1.

A similar plate like bracket 4 is 'formed with a longitudinally'extending slot 5 and this bracket 4 is operatively connected with the bracket 1- through the medium of the lazy tong structure designated generally by the numeral 6. The lazy tong structure includes a series of vertically disposed intersecting cross arms that are pivotally secured togetherat their points ofintersection and are further pivotally connected together at their adjacent ends in the manner well known in the art. I

The lower end of the innermost cross arm 7 is pivotally secured to the lower end of the bracket 1, while the upper end; of the inner-. most arm 8 is operatively connected to the. upper end of the bracket 1 through the medium of the connecting link 9.

In a similar manner the upper end of the outermost arm 10 is pivotally connected ,to the upper end of the bracket 4 while the lower end of the outermost arm 11 is operatively connected to the lower end of the bracket {through the medium of the link 12. In Figure 1 of the drawing, the lazy tong structure is disclosed as" being extended and for the purpose of maintaining the lazy tong structure in its proper vertical position there is provided the horizontally disposed bracing means designatedgenerally by Hie numeral 13, said bracing means also consisting of a lazy tong'structure: Thelazy tong. structure constituting; the bracing means is however slightly difierent in its construction than the vertically disposed lazy tong structime forming the connection between the festly when thelazy tong structure 6 is in its extended position, the horizontally disposed lazy tong structure will also be extended.

Also when the lazy tong structure 6 is col,-

lapsed, the lazy tong structure 13 constitutes the bracing means for the a orementioned lazy tong structure 6 will also be collapsed whereby to provide a compact structure that will not occupy anyconsiderable' amountof space.

The book supporting frame is designated generally by the numeral 17 and the same comprises the central frame bar 18. The upper relatively narrow bars or strips 19 and 20 are pivotally secured attheir inner ends to the outer or front face of the upper end of the central vertical bar18. Similar bars 21 and 22 are secured in a pivoted manner at their inner ends to the lower end of the central bar 18. The outer ends of the upperand lower horizontal bars; are operatively connected to the upper and lower. ends of the respective side bars 23' and 24.

Intermediate brace bars

25 and 26 are secured at their ends to the side bars 23 and .24 respectively at the central portion thereof, the inner ends of these brace'bars being operatively connected to the intermediate portion of the vertical central bar 18. A strip 27 is secured on thefront face of the central bar 18 to provide a rest-or shoulder -for the inner ends of the

central brace bars

25 and 26 as clearly illustrated in Figure This will maintain the frame in its assembled position and pivoted at each of the corners of the'frame is the spring clip 28 that will engage the four corners of a book and maintain the'same in proper position on the-frame. In addition, wire fingers 29 are secured to the side bars forholding the pages of the book in an open position, it'bei'ng understood of course that the spring clips 28 will engage the cover of the book for holding the same open.

Theframe 17 is suspended fromthe bracket j 4'and the suspension means comprises an upper arm'30 thatis formed at its upper end with anenlargedeye through which extends I a bolt 31 that is operable within the slot 5 formed in the plate-like bracket 4,ra wing nut (not shown). being threaded on the threaded end of the bolt for holding the arm in any vertically adjusted position on the bracket." The lower end of this arm is disposed laterallys' for cooperation with the upwardly disposedend of the lower arm 32, the lower end 0fWhICh-IS'PIVOtally secured to the rear face of the upper portion of the central bar 18 of I so the book frame '17 through the medium of the ,bolt 33. .p The laterally disposed abutting endsof the'upper and lower arms are formed with registering openings to receive the bolt 34 and a nut 35. is; threaded on the end of the bolt.

,This construction provides a means whereby directions and in various the'book fr'ame may be adjusted" in various positions with re-.

--'spe1ct-w the bracket4 so that the frame may cludes a pair of

upper bar members

37 and 38 that are pivotally connected together at their adjacent ends, a similar pair of lower bar members being designated by the

numerals

39 and 40, respectively. The outer ends of the upper and lower bars are secured to the respective ends of the side bars 41 and 42. This provides a substantially rectangular shaped frame, andithe upper bars 37 and '38 are formed with suitable notches in the upper edges thereof to engage headed pins that are carried by therear side of the upper bars 19 and 20 respectively of the main frame 17, the upper bars'of the supplemental frame will be disposed in alinement with the upper bars of the main frame and the end bars of the supplemental frame'will be dis-.

posed beyond the end or side bars of the main frame, and alsothe bottom bars of the supplemental frame will be disposed below the bottgm bars of the main frame. This is clear- 1y illustrated in Figure 2 of the drawing.

Brace bars 43 and 44 are pivotally secured at their outer ends to the intermediate portion of the side bars 41 and 42, respectively, of the supplemental frame 36 and the inner. ends of these'braee bars are formed with hooks for detachable engagement over headed pins 45 and 46 arranged on the side bars and the manner in which these brace bars cooperate with the headed pins is clearly shown in Figure 2. This construction is further strengthened by havingthe free ends of the lower spring clips 28 formed, with hooks 47 that engage over suitable headed pins48 that are carried by the lower horizontal bars 39-and 40 of the supplemental frame 36 when the lower spring. clips are disposed downwardly in a vertical position as also clearly shown in Figure 2..

The supplemental frame is provided with a series; of springclips designated by the numeral 49 similar to thespring clip 28 as sociated with the mainframe 17 and in a similar manner the side bars of the supplemental frame carry the spring wire fingers 50 that are similar to the spring wire fingers 29 secured on the side bars ofj'the main frame. In this manner, a relatively'large book or p 23 and 24 respectively of the main frame 17,

. frames when the same are assembled together. It is of course tobe understood thatbooks of a smaller size will be supported on the main frame and the supplemental frame can be readily and easily removed or attached description that I structure, both of said lazy tong structures whenever necessary.

It will thus be seen from the foregoing have provideda novel book holder that can justed to a bed post, and when not in use, the book holder may be collapsed or folded in such a manner as to provide a compact structure for disposition adjacent the bed P While I have shown the preferred embodiment of my invention, stood that various changes in the size, shape and arrangement of parts may be, resorted to without departing from the spirit and scope of the appended claim.

Having thus described the invention, what I- claim as new is In structure of the class described, a bracket for attachment to a support, an additional bracket, a vertically arranged lazy tong structure including a series of vertically disposed intersecting cross arms piv otally secured together at their points of intersection, the outermost arms being pivotally connected to the adjacent brackets, a horizontally arranged lazy tong structure for bracing the vertically arranged lazy tong structure, said horizontally disposed lazy tong structure including a plurality of angular lugs secured on the opposite sides of the points of intersection of the cross arms of the vertically disposed lazy tong structure, pivotally connected arms secured at their outer ends to their respective lugs on the respective sides of the vertically disposed lazy tong being adapted for simultaneous operation.

In testimony whereof I affix my signature. LEROY EDMUND STAGKPOLE.
