BRACKET.

The invention "contem lates the use of a pair of spaced and ad ustab1e supporting arms or brackets, and a brace or strut for engagement againstabuilding. wall beneath tical application of the principles .0 my

- U terial, and is designed to rest upon the tops invention. u Figure 1 is a perspective, view of the bracket showing in dotted lines a' portion of a window frame and. a window sill, together with a shelfyto illustrate the general arrangement .of parts. Figure 2 is 'an enlarged detail] sectional 2 view transversely of a portion of the shelf, showing the retaining device between one of thebracketarms and the shelf."

Figure 3 is an enlarged detail sectional view of one of the bracket-arms showing a cushion thereon for the shelf. I a Figure 4 is a perspective view of a slightly modified form of bracket arm.

In order that the'general assemblyand arrangement of parts .ma readily be under- 5 stood I have'illustrate in Figure 1, in dotted lines a portion of a window frame F and thewindow sill S, it being understood that the bracket is detachably supported at the exterior of the window from the sill and against the wall of the building below the sill. I

The bracket is preferably made up of metal and is adjustable to suit various widths of windows, a pair of spaced supporting hooks 1' and 2 forming part of the equipment." These hooks are secured as by threads in the window sill at the desired spaced locations and the bracket as a whole is supported therefromin a detachable manner.

Two spaced bracket arms indicated as a whole by the numerals 3 and 4 are used, each .of which is provided with a perforated lug I 5 at its end to slip over one of the hooks as lndicated in Figure 1. At their-outer ends the bracket. arms are fashioned with in-. turned hooks 6 which form an angular space Appliea tion fi led October-.17, 1925. Serial No; 63,050.

for each arm. In Figures 2 and 3 it will be seen the arms are preferably provided with upper beaded'edges 7 anda reinforcing. or strengthening'web 8, the rounded head or edge 7--being designed to receive and retain a cushion or filler 9. This cushion may be formed by slitting a suitable length of rubher hose or other tubular article of a size to. [it over the beaded edge 7, which will fric-v tion-ally engage the bead and be retained thereon as indicated in Figure 3.

At the underside of each hook 6 in the space at tlie .end of the arm a retainingspring 10 is located and secured to the hook member as by a rivet- 11.

The rectangular shelf indicated as 12 ii;

preferably of wood but may be of other maof the t'wo spaced bracket arms, in contact with the cushion 9 onthe beaded edges of the arms. The outer edge of the shelf is slipped under the hooks 6v into the space provided'therefor at the end of the bracket arms, into frictional contact with the two retaining springs, and the latter hold the shelf in contact with the cushions in such manner as to prevent lateral displacement of the.

shelf. Outward movement of the shelf away from the window is prevented by the hooks 6. The shelf is thus retained in rigid position on top of the bracket arms by means of the retaining springs on the hooks and the cushion or filler 9 on the beaded edges of the arms.

'In connection with the supporting hooks 1 and 2 the bracket is also supported and braced-from beneath by a strut which is ad justable or extensible with the bracket arms for'adaptation to various width of windows or supports.

The strut is of U-shape and comprises a pair of telescopic bars 13 and 14, the latter being tubular. to receive the end of the former, and each bar is fashioned with a right angle arm 15. These arms are connected by a pair of telescopic brace rods 16 and 17, the

latter being. tubular to receive the former,

arid the whole brace is adapted to form a a support, as for instance a towel rack, if desire.

The free ends of the arms 15 are bent or twisted to form pawls 18 that are adapted to engage a pair of selected rack teeth 19. fashioned in the under edge of the web 8 of each arm. 1 By means of 'the strut the bracket arms andshelf may be adjusted in horizon- I tal position and there held for the performarms by means of a pair of pivoted'links 20' with pivotal connections 21 and 22 to the "strut arms 15 and bracket arms 3 and 4 respectively.

The strut by means of this three point suspension at each end of the bracket thus forms a rigid bracket structure for the sup, port of the .shelf 12 and in connection with the hooks land 2 the Whole combination of parts is retained in detachable position atthe exterior of the window.

In the modified structure of Figure 4 the hooks 1 and 2 are employed in connection with the perforated lug 5 at the end of the bracket arm 23, which arm at its outer end is provided with -a retaining hook 24 for the shelf.

A pair of spaced struts or braces 25 are here employed each made up of a pair of metal straps having oppositely extending feet 26 .to engage the building wall beneath the bracket arms. The braces 25 are pivotaily connected with the bracket arms by means of links 27 and a pin 28 at the outer e'nd of each brace is used to engage a selected notch, or rack tooth 29 in the under edge of the bracket arm.

sible supporting strut and pivotal links between said strut and arms, said arms having beaded edges, tubular cushion members on said edges, hooks at the free ends of said arms, and retaining springs carried by said hooks for engagement'witlna shelf.

' 2. The combination of a pair of spaced detachable bracket arms having. end hooks,

beaded edges and rack teeth, of an extensible st-rut having pawls to engage said teeth, an extensible rack-rod connecting said strut, pivoted links between the strut and said arms, cushions on said beaded edges,

and retaining springs secured to said hooks.

In. testimony whereof I afiEiX my signature.
