' a BRACKET-SUPPORT.

, Specification of Letters Patent. Patented N 20 191'? Application filed September 22, 1915. Serial No. 52,055.

To all whom it may concern:

Be it known that I, WILLIAM F. Posrrnns,

a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Bracket-Supports, of which the following is a specification.

My invention relates to bracket supports and more particularly to a combined embroidery rack and book support.

The primary object of my invention resides in the provision of an improved supporting means for removable association with the arm of a chair'or other suitable support for holding an embroidery rack in various adjusted vertical and horizontal positions, said rack being incidentally removable to permit of the application of a book support which can be held in like manner, thereby providing a device for holding. a rack in a convenient or any desired posit on to permit of embroidery being worked or to maintain a book 01- the like in a suitable position corresponding to the desire of the person who is using the device.

Another object of my invention resides in the improved means for connecting an embroidery rack to a support as well as novel means for obtaining a horizontal ad-j justed position of the rack or book support.

A still further object of my invention resides in the provision of a device of the character described that is simple in construction, efficient in operation and one that can be manufactured and placed on the market at a minimum cost.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification. j

In the drawings: 1

Figure l is a side elevational view of my invention associated with the arm of a chair, the dotted lines illustrating the horizontal and vertical adjustments obtained;

Fig. 2 is a top plan view of the embroidery rack;

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2 in the direction in which the arrow points, illustrating to advantage the novel means for connecting the embroidery rack to the support, the dotted lines illustrating an adjusted position of the'rack;

F 1g. 1s a rear elevatlonal view of a book support associated with the vertical adjusting rod; and

Fig. 5 is a side elevational view of the same.

Referring more particularly to the drawings in which similar reference numerals designate like or corresponding parts throughout the different views, I provide my improved supporting means in this instance including a rod l having a head 2, the rod having rotatably mountedthereabout a sleeve 3. Arms a and 5 extend latorally from the sleeve 3 in spaced parallel relation to each other, the arm 5 being shorter and provided with an opening in which is mounted a clamping screw 6, said screw being operable for removably maintaining .the arm 4 in engagement with a chair arm 7 or like support. Rotatably associated with the rod is preferably a U- shaped supporting member generally designated 8, the arms 9 of which are journaled about the rod adjacent the vertex. A spacing sleeve 10 is arranged about the rod and between the; arms 9 for facilitating the clamping of the Ushaped member in various positions through the medium of a set screw 11. The lower arm of the U-shaped member extends upwardly and has its terminal bent into parallelism with the upper arm. Both of the terminals of the member are provided with openings, between which there is rotatably mounted the sleeved end of a horizontally extending rod 12, the mounting thereof being facilitated through the medium of an eye bolt 13, the lower end of which adjustably engages the opening in the lower arm 9 whereby when tightened the arm will be removably held in various positions of adjustment. The outer end of this rod 12 is enlarged and provided with a vertical opening 1d and a horizontally extending opening 15 in the free end thereof which communicates with the vertical opening 1 1, thehorizontal opening having a set screw 16 adjustably mounted therein for a purpose to be hereinafter described.

. The vertical adjusting means of the supporting bracket in this instance consists essentially of a rod 17 having an upper looped end 18 about which loop are arranged depending spaced ears 19 of the embroidery rack 20, the ears are provided with open- I
