As shown in Figs. 4, 6 and 7 the slide bar 39 has a lower wall arranged to slidably rest on the upper surface of the comb-'like bar '38. The lower .Wall 58 terminates in upwardly extending side walls 59 and Sil which extend lengthwise of the slide bar 32. The side walls 59 and E552 terminate at their upper ends in angularly extending 'iianges Si and 32 respectively, which are arranged to lie l.directly under the inner surface of the `upper 'wall wall 40 of the hollow bar 31.
"'L-'shaped apertures 63 are formed at spaced points in the lowerfwall 58 of the slide bar 3Q and the main ',leg of each L-shaped aperture S3 is z continued into a continuation aperture Sd formed in the wall 53 as shown in Figs. 5 and 7. As shown in Figs. Ll, 12 and 13 the main leg of the L-shaped aperture 63 is in communication with the hori- Zontal leg 55er the L-shaped aperture G3 and the slideb'ar 39 canbehmoved lengthwisef'fr'om y'the shown in Figs.` 13 and leac'h Lshaped aperture 63 is in such position that itsmain leg isin register withanapertu 15in the hollow bar 31.
It will be seen, therefore, that in this position the end portions 28 of the straight rods 2! can be laterally moved into and out of the Yupper bar i9.
It will alsc'be seen that the upper end portions 28 of each straight rod 24 ishgripped by two reentrant teeth 52 on the comb-like bar 323 the function of which is to prevent the straight rods 24 from falling out of the Lipper bar I 9 when the slide bar 39 is insuch position that the main leg portion of an LIshapedV aperture 63 is in register with an aperture 45 in the hollow bar 31.
AH lock isprovided to hold the slide bar 39 against undue sliding from the Vposition shown in Figs. 4 and l2 to the position shown in Fig. 13. The lock comprises aY spring latch nger GB'and a keeperk61. rIhe spring latch finger 65 is a leaf spring type member secured at one end to the slide bar 39 and having an angularly extending end portion 68 arranged `to hook over an end i portion 69 of the keeper 61 when the slide bar 391s in the position shown in Figs. 4 and 12. The keeper 6,1 ischannel-shaped in cross-section and has spaced side walls 1E) and'll cooperatively dening a passageway 12 for accommodation of a lug 13 on a key 14 shownin Fig. 3. The keeper 61 is provided with ilanges 15 which are welded or otherwise secured to the inner surface of the wall 42 of the hollow bar 3 1 and so that thepassageway 12 is in registerv with one leg 15 of an inverted L-shapedl aperture ll'forrnedinthe ijOIltWall 42 of the hollowbar. 31. The other leg 18 of the L-shaped aperture 'Villes4 above the position of the keeper 61 and extends toward an end portion of the hollow bar 31 and is providedto accommo- The leg portion 18Hof the L f'shaped aperture 1l`is longer thanv thewidth of'thej shankfportion 19 of' the ,key lll. The wall 'li of `thekeeper 61'te`rminates at Yits inner end irian angularlvexte'nding"'arm portion so equipped with guidepnte'sr'writh 39, the flange 32 being, in effect, an offset and |broken continuation of the flange 62 and being narrower than the ange 62. A notch 83 is formed in the ange 82 to receive the lug 13 on the key 1li, the notch 83 being considerably wider than the thickness of the lug 13 and being so located that the notch 33 will be in register with the passageway 12 in the keeper 51 when the slide bar 39 is in the position shown in Figs. 4 and 12 and will be out of register with the passageway 12 in the keeper 61 when the slide bar 39 is in the position shown in Fig. 13.
The slide bar 39 can be unlocked from the keeper 61 and can be moved longitudinally in the hollow bar 31 by means of the key 14 which can be thrust endwise into engagement with the latch nger 63 and pressed against the latch finger 36 to flex the latch linger to such extent that the end portion 3S is moved out of hooked engagement with the keeper 81. The key 14 can be thrust further to bring the lug 13 into the notch 83 and then be used as a lever to move the slide bar 33 to the position shown in Fig. 13 and then back to the position shown in Fig. 12. When the slide bar 39 has been moved by means of the key 1li to the position shown in Fig. 13 the key 14 cannot be withdrawn until the slide bar 39 is returned to the position shown in Fig. 12, in which case the key 14 can be withdrawn to allow the spring finger 63 to engage the keeper 61 to hold the slide bar 39 in locked condition.
The book holder' shown in Fig. 1 can hold a plurality oi books in convenient position for ready reference to the books without releasing the books from the book holder. Each book can be mounted in required place by attaching a rod assembly 23 to each book and placing the rod assembly 23 in required position in the support I6 which is secured to the wall i8.
Assuming that it is desired to mount a telephone directory in the book holder and that the key 14 is not in the book holder and the slide bar 39 is in locked condition. In order to mount the telephone directory in the book holder i5 the key 1li must be inserted in the upper bar structure I9 by way of the inverted L.shaped aperture 11 until the key 1li presses the latch linger 3S out of engagement with the keeper 91. With the latch finger 36 pressed out of engagement with the keeper 31 and with the lug 13 in the slot 83 the key 14 can be operated as a lever to the right of the position shown in Fig. 12 to the dot-dash line position shown in Fig. 13. In doing this the slide bar 39 is moved to the position shown in Fig. 13 and so that the slide bar 39 is in such position that the main leg portions of the inverted L-shaped apertures 63 in the slide bar 39 are in register with associated apertures and 50 in the hollow bar 31 and the comb-like bar 38, respectively. In this case the comb-like bar 38 prevents the rod assemblies 23 from falling out of the upper bar is but a rod assembly 23 can be removed from the bars I9 and 23 simply by pulling the upper portion of the rod assembly 23 outwardly from Ibetween the reentrant teeth 52 and through the apertures 59 and 45 and then lifting the rod assembly 23 until the lower end portion 29 is out of the lower bar 2t. The removed rod assembly 23 can be disassembled by withdrawing the straight rod 24 from the book-attaching rod 25. To mount the rod assembly 23 on the book the book is opened and the book-attaching rod 25 is placed between leaves of the book and so that the eyelet portions 26 and 21 extend rear- Wardly of the book 84 as shown in Fig. 9. The
straight rod 2f!l is then placed along the outside of the back of the book 81 and through the eyelet portions 26 and 21 of the book-attaching rod 25.
With the rod assembly 23 attached to the book 33 as shown in Fig. 9 the book can be mounted in place by simply inserting the lower end 29 of the straight rod 2li in an aperture in the upper wall 313 of the lower bar 23 and then laterally thrusting the upper end portion Z8 of the straight rod 24 'through the apertures 5 and 50 of the hollow bar 31 and the comb-like bar 38 until the reentrant teeth 52 snap into gripping engagement with the upper end portion 23 of the straight rod The length of the straight rod 24 and the spacing of the bars I9 and 29 is such that the straight rod 2:1 can be lifted out of the lower bar 29 only when the upper end portion 28 of the straight rod 3d is entirely clear of the upper bar i9. Jillian the book 33 is properly supported in the book holder l5 the slide bar 33 can be moved by means of the key 1li from the position shown in Fig. 13 to the position shown in Fig. l2 to prevent lateral withdrawing of the straight rod 24 from the upper bar structure i9. In the position shown in Fig. is the key lit can be withdrawn :trein engagement with the slide bar 39 and removed from the book holder lli since the lug 'it on the key ifi is in register with the passage- 12 in the keeper Cil. When the key 'M is withdrawn from the slide bar 39 the spring latch 3S under its own spring tension moves into engagement with the keeper 31 and so that the angularly extending end portion 33 of the spring latch :Finger 355 'cornes into hooked-over engagement with the edge portion 69 of the keeper 61 as shown in i. In this position any straight rod 2li properly mounted in place in the support i3 is lock-ed by means of the slide bar 33 against removal from the support I3.
When a book 34 is locked in the book holder and it is desired to remove the book the slide bar 33 must be moved to the position shown in Fig. 13. This can be done by inserting the key 14 in the book holder l5 until the spring latch nnger @t is pressed out of engagement with the keeper 3l and the lug 13 is in the slot 33 and then using the key 11i as a lever to move the slide bar 33 lengthwise to the position shown in Fig. 13. In this position the upper end of the straight rod 212i can be pulled laterally from between the reentrant teeth 52 and through the aperture in the hollow bar 31 until the upper end of the straight rod 24 is clear of the bar structure E3. The straight rod 24E can then be lifted out oi' the lower bar E9 until the rod assembly 13 on the book 34 is released from the support ld. The rod assembly 23 can be released from the book 33 by withdrawing the straight rod 23 from the bookattaohing rod 25 which can then he withdrawn from between pages of the book 83.
