The book holder H is formed upon aflongitudinally
slotted sleeve 64 which slideably and telescopically ?ts
over the holding nut 56 and the sleeve 57. A lug 65 is
affixed to the ?anged end of. the sleeve 57 and a short
slot 66 is formed in the sleeve 64 toreceive this lug and
to force both sleeves to rotate in unison. The sleeve 64
is also slotted as at 67 at a position diametrically op
posite to the position of the lug 65 and a clamp 68 em
braces the sleeve 64. This clamp is adapted to squeeze
the sleeve 64 as by a knob~nut 69 to hold the sleeve in
a tight position upon the under sleeve 57 and to hold the
book holder assembly upon the swivel means 13.
The book holder includes a central rod 70 which is

from each side of the bar 70'. A ?xed end-abutment
71 is also a?ixed to the end of the sleeve 64 in a position
which is transverse to the axis of the sleeve and the bar
70. The under edge of this end abutment is turned in

extending ‘the wires 80 at each end of the shelf and adjust

tail but it is obvious that others skilled in the art can

which are within the spirit and scope of my invention.
Hence I desire that my protection be limited, not to the

upper scope of the appended claims.
I claim:

permit rotation of the clamp about the axis of the arms
of the T leg, a lock bolt spanning the other crotch of the
clamp and being adapted to bring the legs of clamp to
gether to lock it upon the T leg, a shaft extending from
pages lying against the shelves 73, one shelf being at
the top and the other shelf being at the bottom of the open 40 the side of the bolt and between the legs and along the
axis of the clamp, a ?anged sleeve rotatably mounted
