UNHTED stares SIMION EHRICH, OF BRONX, NEW YORK.

BRACKET ATTACHMENT.

Application filed March 6, 1922. Serial No. 541,424.

To all whom it may concern:

Be it known that I, SIMON EHRICH, a citizen of the United States, residing at Bronx, in the county of Bronx and State of New York, have invented new and useful Improvements in Bracket Attachments, of which the following is a specification.

This invention relates to'bracket attachments and has for one of its objects, the provision of an article supporting attachment which is capable of convenient application to or removal from the arm of the bracket and one which will be adjusted in the length of the arm as well as around the axis thereof.

Another object of the invention is to provide an adjustable article supporting device and means incorporated therein for holding the device in its positions of adjustment.

A still further object of the invention is to provide an article supporting device of sectional formation, the respective sections constituting bracket embracing clamps which can be adjusted into relatively close confinement with the bracket and which will co-act with a supplemental yielding retaining means for holding the device in its position on the bracket.

With the above and other objects in view which will appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out in the claims.

In the accompanying drawings, has been illustrated, a single and preferred form of the invention, it being, however, understood that no limitations are necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

Figure 1, is a perspective view of a bracket showing the application of the invention thereto.

Figure 2, is a perspective view of the device showing parts thereof separated for the purpose of clearness.

Figure 3, is a vertical section through the device showing its application to the arm of a bracket.

I do not limit myself to any particular use to which the invention may be put but have designed an attachment which is capable of many uses and one which is broadly intended to adjustably support an article upon the arm of a bracket, thereby permitting the article to be moved to any desired position both in the length of the bracket and at points around the longitudinal axis thereof. a

In order that a clear understanding of the invention may be had I have herein illustrated a bracket 5 which includes a supporting arm 6 having angular ends 7 and 8. My lmproved article supportlng device or attachment is mounted on the arm 6 and the same comprises a base section 9, an intermediate clamping section 10, and an upper section 11.

The lower section 9 is bifurcated at 12 and threaded at 13. This section is formed tion 10 is adjustable over the threaded por-' tion 13 of the lower section 9 and at diametrically opposite points, this intermediate section is provided with semi-circular notches 19. The bifurcation 12 is U-shaped as shown in Figure 2, and incident thereto, the base wall of same is also semi-circular. This base wall is therefore intended to co-act with the semi-circular recesses 19 so that the arm 6 of the bracket can be passed into the bifurcation 12 and secured between the mating or clamping sections 9 and 10. The section 11 is threaded interiorly to be accommodated by the external threads of the section 9. In this manner, said section 11 can be adjusted against the intermediate section 10 and the latter and the base section 9 drawn into clamping engagement with the aforesaid arm 6. The spring 15 is sufiiciently strong to hold the attachment in any of its adjusted positions, both in the length of the arm 6, and around the longitudinal axis thereof. In order that the attachment can be moved to any one of a number of positions, I provide the same with a suitable handle 20. The section 11 is provided with a threaded passage 21 which is adapted to receive a correspondingly threaded arm 22 of the article 23 that is to be adjustably supported from the bracket. This article as herein illustrated is in the form of a magnifying glass and the same may be adjusted to any position between the angular extensions 7 and 8 of the arm 6. The sectional formation of the attachment will permit of its convenient application upon the arm 6, or a removal of the same therefrom. Were the attachment formed as an integral element, it would be very dificult, if not impossible, to apply the same to the arm 6 in view of the angular extensions 7 and 8. In order that the tension of the spring can be varied against the ball 18, I provide the hereinbefore mentioned nut 16, which can be turned against the spring so as to regulate its tension against said ball and thereby govern the frictional contact of the latter with the arm 6.

I do not wish to be limited to the form of spring 15 herein mentioned as any suitable well known yieldable device may be employed in lieu thereof. I also do not wish to be confined to the form of bracket arm 6. This arm is shown as of circular formation in Figure 3, but in this respect and for certain purposes of the invention, the cross sectional design of said arm can be changed to suit varying purposes.

What is claimed as new is 1. A bracket attachment comprising, threadedly connected members between which the arm of a bracket is adapted to be interposed so that the member can be moved in the length of the arm and turned around the axis thereof, and yieldable means carried by the member including an axially movable ball for engagement with the arm of the bracket.

2. A device of the character described comprising a base section having an axial bore, an intermediate clamping section, and an upper section, the upper section being threadedly engaged with the lower section and bearing against the intermediate section, the lower section being bifurcated for the reception of a rod in operative relation to the intermediate clamping section, and a yieldable ball operating in the bore and movable with respect to the bifurcated portion.

In testimony whereof I have aflixed my signature.

SIMON EHRICH.
