BOOK-SUPPORT ATTACHMENT Application filed July 14,

This invention relates generally to stands havingmovable arms for supporting books, music, periodicals and other articles, and refers more particularly to stands of this type which may be readil attached to-desks or other articles of furniture so thatthe books, etc, may be swung over the top of the desk to a convenient position for use by a person seated at .the desk.

One of the essential objects of the invention is to provide a stand of this type that may be easily and quickly attached to or removed from a desk or other standard article of furniture without marring the same.

Another object is to provide simple and eifectivemeans for attaching the stand to the desk so that the weight of the desk may be utilized instead of a heavy base for the stand to prevent the latter from ti ping over when a heavy book or other artic e is placed upon the supporting arm of thestand.

A further object is to provide means for preventing the stand from turning on the floor relative to the desk when the latter Still another object is to provide a strong and durable stand that is simple in construction and that can be manufactured at comparatively low cost.

With the above and other objects in view the invention consists in certain'novel fea-. tures of construction, combination and arrangement of parts as will be more fullydescribed and particularly pointed out in the appended claims.

Referring now to the drawings in which 11kt} characters ofrefereuce designate corresponding parts throughout the several and the upright sections 7 of the standard I 3, While the tube 8 is preferably bent at its opposite ends to-provide the leg .por

tions 9. A suitable tube 10 is secured to the'leg portions of the tubes 6, while suit able tubes 11 are preferably connected at their opposite ends to the leg portions 6 and 9 respectively of the tubes 5 and 8 to brace and reinforce the same.

In order that the arm 4 may be swung freely about the standard 3 and atthe same time will have apositive support, I preferably provide suitable metal castings 13 and l ithat are mounted upon the upright sections 7 of the standard 3 asshown in Figure 2 of the drawing. The casting 13 is provided with a central opening 15 for receivingthe vertical pivot portion 16 of the arm 4 and has depending lugs 17 which fit snugly within the upper ends of the upright sections 7 of the standard. The casting 14 is preferabl sleeved upon the sections 7 at the lower on s thereof and is provided intermediate its ends with a tapered socket 18 which forms a bearing for the tapered lower end of the vertical pivot portion 16 of the' arm 4. Any suitable means may be mounted on the horizontal arm4 for supporting articles of different kinds. As shown, I preferably provide a suitable holder19 for books,

catalogues, music and the like, having a central stud 20 that preferably extends through a suitable boss 21 at the free end of the arm 4 and is clamped in position by means of a suitable winged nut 22 threadedly engaging the stud 20 below the arm 4. Thus, with this construction the arm 4 may be readily swung over a suitable flat top desk 23 for supporting books, etc, in a convenient position for use by a person seated at the desk. Any suitable means such as a set screw 26 threadedly engaging the casting 13 may be employed for holding the arm 4 in adjusted position.

In order that the arm 4 may be raised orv lowered as desired above the top of the desk, the casting 14 is preferably adapted to be moved vertically upon the sections 7 of the standard and may be held in an adjusted position by means of suitable set screws 25. t

In order that the weight of the desk may be utilized for preventing the stand from tipping over when a catalogue or other heavy article is placed on the holder 19, I prefer-- ably provide a horizontal bearing plate 27 for taking the pressure at the bottom of the desk. As shown, the plate 27 is preferably formed of two telescopically engaging secs tions 28 and 29 respectively, having upstanding flanges 30 at their outer ends for clamping engagement with the sides of the drawer receiving end portion 31 of the desk. If desired, suitable felt pads 32 may be secured to the inner faces of the flanges 30 to prevent the latter from marring the desk. Any suitable means such as a bolt 33 may be used to adjust the sections 28 and 29 respectively of the plate 27. As shown, this bolt extends freely from a depending lug 34 on the section 29 and threadedly engages a depending lug 35 on the section 28. Thus, the clamping engagement with the desk may be easily and quickly effected by merely rotating the bolt 33..

For preventing the frame 2 from turning relative to the desk when the latter is moved for any reason, I preferably provide three vertical bolts 39 that are carried by the frame 2 and are adapted to engage suitable sockets 40 projecting downwardly from the sections 28 and 29 respectively of the hearing plate at the outer free ends thereof. As shown, two of the bolts 39 threadedly engage an arm40 that is slidably mounted on parallel rods 41 extending between the tubes 6 and 8 respectively at the opposite ends of the frame while the third bolt 39 preferably engages an enlargement 42 at the outer end of a horizontal arm 43 projecting laterally from an arm 44 that is slidably mounted on the. parallel rods 41. Thus, with this construction, the arms 40 and 44 maybe readily adjusted on the parallel rods 41 to accommodate drawer receiving portions of different widths and to permit the stand to be moved out or in with respect to the desk according to the distance the top of the desk projects over the end walls thereof.

In order that the stand may be raised or lowered with respect to the desk when necessary, I preferably provide suitable feet 45 which threadedly engage the lower ends of the leg portions 6 and 9 respectively of the tubes 5 and 8. Thus, any one of these feet may be adjusted-with respect to the leg por- Moreover, the form of attachment is such that the weight of the desk is utilized to prevent the stand from tipping over, consequently it is not necessary to provide the stand with a heavy and cumbersome base. Another important feature is the provision ofthe vertical bolts 39 which are engageable with the sockets 4O projecting downwardly from the sections 28 and 29 respectively of the bearing plate 27 to prevent the frame and standard from turning relative to the desk when the latter is moved for any reason.

Furthermore, it will be apparent that the stand may be readily attached to the drawer receiving portions of desks and other articles of furniture of difierent widths, inasmuch as the bearingplate is formed of telescoping sections which may be adjusted as desired.

Inasmuch as the casting 14 is sleeved upon the vertical sections 7 of the standard 3, it is also readily apparent that the bearing 18 for the vertical portion 16 of the arm may be adjusted vertically so that the arm 4 may be raised or lowered as desired above the top of the desk. Another important feature is the provision ofthe adjustable feet 45 which permit the stand as a unit to be raised or lowered as desired.

In Figures 7 to 9 inclusive of the drawings I have provided a slight modification in which the frame 50 of the stand is preferably supporting a holder (not shown) may be ably extends downwardly through the cross bar 57 and is provided with an annular flange 62 that rests upon a suitable ball race 63 mounted on the crossbar 57. Thus with this construction, the sectional bearing plate 65 is preferably slidable vertically on the tubes 55 of the standard and is adapted to be held in adjusted position against the drawer receiving portion of the desk by means of a single ad usting screw 66 which preferably threadedly engages the liFWflIdly projecting inverted substantially shaped portion 67 of the end casting 52 of the frame. As shown, the section 68 of the plate is preferably provided at its outer end with a lateral extension 69 having spaced bosses 70 which receive the tubes 55 of the standard and are adapted to slidably engage the same. The extension 69 of the section 68 is also provided with an intermediate boss 71 that receives the vertical pivot portion 61 of the arm 59 and slidably enga es the same. Thus the engagement of the bosses 70 with the tubes 55 will effectively prevent the frame 50 from turning relative to the desk when the latter is moved for any reason. Inasmuch as the rods 53 threadedly engage the castings 51 and 52, it is also readily apparent that the frame may be readily knocked down for shipping or storing purposes.

While it is believed that from the fore going description the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.
