To rl/ZZ whom it may concern,.-
Beit known that I,- WILLIAM ARTHUR LUBY, a citizen of the United States, residing at Kansas City, Jackson county, Missouri, have invented a new and useful Attachment for Book or Music Racks, of which the following is a specification.
My invention relates to attachments for book or music racks; and it consists in certain novel features of construction and organization hereinafter described and claimed. On January 23, 1900, Patent No. 641,784 was granted to me on Attachments for booksupports, the same consisting, essentially, of a spring-rod secured to the shelf of the support and projecting beyond one end of the same, and-an arm pivoted to the projecting end of said rod and adapted to assume an 0perative position above or an inoperative position below said shelf; and my present inventioncontemplates, primarily, a construction whereby the pivoted arm may be positioned operatively7 or inoperatively, as described, without the necessity of projecting the spring-arm beyond the end of the shelf, where, as practice has shown, it is somewhat in the way when the rack is folded.
- A further object is to provide a construction of neater and more ornamental appearance without sacrificing any of the practical advantages of the patented structure.
Other and secondary objects of the invention hereinafter appear, and in order that it maybe fully understood reference is to behad r to the accompanying drawings, in which- Figure 1 is a perspective view of a-bookor music rack provided with an attachment embodying my invention. plan view of the same with the attachment folded to inoperative position. Fig. 3 is a detail View showing the rack in end View and a modied form `of the attachment in its inoperative position.
Referring noW to the drawings in detail, wherein like reference-numerals designate corresponding parts, Agdesignates a book or music rackof collapsible or folding type, and B the shelf projecting from the lower edge and forming a part ,of the rack.
The attachment, composed of dat spring metal, is constructed as follows:
-1 designates a spring-arm twisted near one Fig. 2 is an inverted.
end, as at 2, to provide the short arm 3, fitted atwise against the under side of the shelf B near its inner end and secured rigidly thereto by rivets 4 or their equivalent, and formed integral with the arm 3 or riveted thereto, as shown, is a depending forwardly-disposed hook 5, for a purpose which hereinafter ap'- pears. The opposite end of the spring-arm terminates at the outer end of the shelf near its rear corner or edge, as shown clearly in Fig. 2.
6 designates the leaf-holding arm of the attachment, said 4arm being by preference of greater length than arm 1 and formed about its middle with a loop 7, projecting forwardly. At one side of said loop is provided a loop formed by the arm curving gradually and gracefully outward toa suitable distance and then bending inward abruptly, as at 8, and terminating in a short arm 9, extending about at right angles to the body of arm 6, said arm 9 terminating in a lug 10, frictionally pivoted or hinged in any suitable manner to the free or outer end ofarm 1, the arrangement being such that the pivotal or hinge operation of the leaf-holding arm will take place in a plane about at right angles to the approximately horizontal shelf, as hereinafter explained.
Pivoted to the free end of the leaf-holding arm is a supplemental arm 11,which is adapted to operate pivotally in a parallel plane and to befolded snugly back against the leaf-holding arm, as shown clearlyin Fig. 2.
By reason of the tendency of the free end of the spring-arm to move rearward and maintain itself when unresisted adjacent to the rear outer corner of the shell it is obvious that the leaf-holding arm carried by and at the front side of arm 1 will when occupying its inoperative or flded position extend approximately parallel with arm 1 and be held by the latter upon and against the supportinghook 5, said hook being designed to hold the attachment compactly folded when not in use and to relieve the friction-hinge of the weight of said arm at such time, it being obvious that Asaid hinge would work loose in a comparatively short time if under the 'necessity of supporting arms 6 and 11 snugly up against the bottom of the shelf unassisted. Springarm l holds the arm 6 pressed back against the vertical portion of said hook, as herein- IOO beforestated,andthereforevutilizesthespringl wholly within the ends of the rack when clearly, and it will-be noticed that the loop formed at the hinged end of the leaf-holding arm is of sufdcientwidth,.measured between .f its portion 8 and the arm 1, to project slightly beyond the front edge of the shelf, ywhenthe spring arm occupies the position shown clearly in Fig. 2, to enable the operatorby grasping the opposite end of the leaf-holding arm and springing it ont slightly to diseugage it from the hook 5 to .swing it in the direction indicated by the arrow, Fig. l, from its position below the shelf-to approximately the position shown in said figure, the forward corner of the shelf passing through the loop in this operation, as'will be readily understood. After the-arm is thus operatively positioned with the shelf projecting into the loop at the lower endof the arm the supplemental arm 1l is swung inward to a substantially horizontal position if it be desired to use the same.
Said arm is not indispensable; but the leaves can `be held withgreater satisfaction and convenience when it is used.
By reason of the-spring tendency of arm l to move rearward it is obvious that this device is equally serviceable in holding open upon the rack a book or sheet'of music.
When it is desired to turn the leaves of the book, it can be most easily accomplished by placing the thumb or finger against loop'7 andvswinging arms 6 and 1l -out beyond the edge of the book, and preliminary to the folding of the rack arm l1 is swung down upon arm 6 and the latter in a direction opposite to the arrow, Fig. 1, until it is disposed below the shelf'and upon the hook 5, depending from the riveted end of spring-arm l. In such position it is obvious that it practically adds nothingrto the bulk of the rack and projects beyondthe latter only at a single pointviz., at the point 8, where vsuch projection is unimportant.
I parent that I have produced a simple, cheap,
ecient, and ornamental attachment l'for book or music racks, which is easy of adjustment to 'permit or prevent turning of the leaves, possessing all of the'advantageous features of the patented device and in addition thereto the desirable features of lying folded and of preventing arms Gand 1l from swinging down inv the way when the rack is being moved from one position to another.
Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-
l. The combination of a book or musicrack having a shelf, of an attachment, comprising an arm secured'to the under side of the shelf 75 and extending longitudinally thereof at all times and of resilient construction so that it shall be capable of movement at its outer end in a plane about parallel with and transversely ofthe under side of the shelf, and a secondarm pivoted at its lower end below the shelf to the first-named arm and capable of swinging to an. operative position above and an inoperative position below the shelf, and provided with a loop near its pivoted end, substantially as and for the purpose set forth.
2. The combination of a book or music rack having-a shelf, ya spring-arm secured to the rack at the under side of the shelf, and provided at its anchored end with a forwardlydisposed hook,andan arm pivoted to said spring-arm and adapted to occupy an operative position abovev oran inoperative position below theshelf and upon the hook, and provided with .a loop near its pivoted end, substantially as described.-
3. The combination of a book or music rack having a shelf, a spring-arm secured to the rack at the under side of the shelf, a leafholding arm pivoted or hinged tothe free end ofthe spring-arm, and provided with a loop into which the shelf is adapted to project and with a finger or thumb loop, a supplemental arm pivoted or hinged tov the leaf-holding arm, and a vforwardlydisposed hook depending from the anchored end ofsaid spring-arm, to receive and su pport the leaf-holding and supplemental arms when folded to inoperative position, substantially as'described.
4. The combination of a book or music rack IOO IIO
,having a shelf, and an attachment, consisting of an arm pivotally supported atk one end from said shelf so as to be capable of swinging onlyin a plane substantially parallel with said shelf and the face ofthe rack,'and provided with a loop near said pivoted end having one' side always underlying said shelf; said arm being of resilient construction so that the part at the side of the loop opposite to the pivotal point of the -arm shall be capable of movement in a plane at right angles to the pivotal movement ofthe arm and thereby accommodate books of varying thickness on the rack, substantially as. described.
In testimony whereof I affix my signature in the presence of two witnesses.
