JOSEPH BORAKS, 013 BOSTON, MASSACHUSETTS, ASSIGNOR TO ELIAS HOWE COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
MUSIC-STAND.
Specification of Letters Patent.
App1ication filed October 17, 1910.
To all whom it may concern."
Be it known that I, JOSEPH BORAKS, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Music-Stands, of which the following is a specification.
This invention relates to music-stands. Heretofore the post has been composed of a base-tube to which the folding legs'are connected, and a removable tube for the rack adapted to slidably engage the base-tube, said sliding-tube having a friction-device to engage the interior of the base-tube which acts to hold the sliding-tube in whatever position it may be set. The parts are usually nickel-plated and highly polished and the sliding-tube is made smaller in diameter than the base-tube so as to slide freely in the hole in said base-tube without abrasion, so that the highly polished surface will not be injured.
This invention has for its object to pro vide the sliding-tube with improved form of friction means for engaging the base-tube, by which said sliding-tube is firmly held against wabbling within the base-tube even when made considerably smaller in diameter than the hole in the base-tube, said improved friction means being of simple construction and admitting of being polished with the tube, and being constructed and arranged to present several narrow points or portions for engagement with the basetube instead of several broad faces, so that even though the polish wears off of its narrow engaging points, the member as a whole is not unsightly when removed from the base-tube.
The invention also involves an improved construction of locking-device for the foldinglegs, which may be automatically moved to engage a sliding-collar on the base-tube to which the upper ends of the braces connected with the legs are attached and to limit the movement of said sliding-collar in a direction to spread the legs and having means for disengaging said sliding collar when it is desired to fold the legs.
Figure l is a side elevation of a portion of a music-stand embodying this invention, the legs being spread. Fig. 2 is a similar view the legs being folded. Figs. 3 and 1 are enlarged longitudinal sectional details of the locking-device for the sliding collar. Figs. 5 and 6 are transverse sectional details of the locking-device taken on the dotted lines 55 and 66, Fig. 3, respectively. Fig. 7 is a side elevation of a portion of the removable sliding-tube. Fig. 8 is a longitudinal vertical section of the same. Fig. 9 is a transverse section of the same taken on the dotted line 9-9, Fig. 8.
(t represents the base-tube of the post, and b the removable sliding-tube which is made considerably smaller in diameter than the base-tube, as represented in Fig.9, so as to slide freely therein without abrasion.
0 represents a collar fixed on the lower end of the base-tube to which the upper ends of the legs 0 are pivotally connected.
(Z represents a sliding collar arranged on the base-tube to which the upper ends of the braces 03 are pivotally connected, the lower ends of said braces being pivotally connected to the legs at points intermediate their length.
The improved locking-device embodying this invention for engaging the sliding-collar (Z when the latter is in its lowermost position and the legs are spread, consists of a resilient plate of flat sheet metal, bent to form a transversely curved portion 0 at one end and shaped to correspond to the curvature of the wall of the base-tube for attachment thereto, and bent at points intermediate its length at e and 6 to form an offset portion to increase the resiliency and augment the stiffness of the plate and to lift its free end portion away from the wall of the tube to provide ample range of motion for said free end portion. Said plate has secured to its free end portion two lugs c and 6 arranged one in front of the other, both of which project through holes in the wall of the base-tube a. The lug e is formed with a beveled end, see Figs. 3 and 4 and the lower end of the sliding-collar d, at a point opposite said lug is beveled, as at 66, from the end of the collar to the hole e in said collar, so that said sliding collar will freely slide along on the base-tube and over said lug e permitting said lug e to enter a hole 0 in said sliding-collar for the purpose of locking said collar in its lowermost position with the legs spread. The distance between the hole 0 and the lower end of the sliding collar is no greater and preferably less than the distance between the lugs e and 6 yet the lug cf is purposely made quite long, so that in case the sliding collar is moved along on the base-tube quickly, it will strike said lug e and its -movement will be thereby checked. Said lug 6 however, is employed particularly as a means to be engaged by the thumb or finger of the user for the purpose of pressing inward the resilient plate to disengage the lug e from the sliding-collar to permit the latter to be moved in the opposite direction on the base-tube when 10 folding the legs.
' The sliding-tube b which freely enters the base-tube has improved friction means at its lower end for engagement with the wall of the base-tube. The improved friction means here shown consists of two or more tongues I), struck or formed out of the metal of the tube, being integrally connected with the tube at the lower end only, and the upper or free ends of said tongues are flattened and broadened so that said flattened and broadened end portions 6 are wider than the holes from which they are struck or formed; and said tongues are extended outwardly, as
shown in Figs. 7 and 8, and have an inherent tendency to spring outwardly, but are prevented from being pressed into the holes out of which they are struck or formed by the flattened or broadened ends thereof. Said flattened and broadened ends of the tongues are arranged in the annular space between the tubes on a chord of the arc of the outer tube and tangential to the inner tube, as best shown in Fig. 9, and when thus disposed the edges of said flattened and broadened ends frictionally engage the curved wall of the outer tube while the portion therebetween is held pressed into engagement with the inner tube. Only these narrow portions or edges of the tongues which engage the Wall are subjected to wear and the highly polished surface formed thereon, which soon wears away, is so slight as not to appear unsightly when the slidlng-tubeis removed from the base-tube. By thus forming the end-portions of the spring tongues a plurality of engaging points equidistantly arranged are provided, which firmly hold the slidingtube against Wabbling even though said tube is made considerably smaller in diameter than the hole in the base-tube, and also hold said tube in whatever position it may be set with respect to the base-tube.
I claim In a music-stand, a cylindrical base tube and a cylindrical sliding tube adapted to be contained therein, said sliding tube having a plurality of tongues struck out of it which are integrally connected therewith at their lower ends only, said tongues having their free ends flattened and broadened and arranged in the space between said tubes on a chord of the arc of the outer tube and tangential to the sliding tube to thereby frictionally engage the outer tube at their edges while the portion therebetween is held pressed into engagement with the sliding tube, substantially as described.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
JOSEPH BORAKS.
