Application filed J'u1y 9, 1915. Serial No. 38,967. V

To all whom it may concern Be it known that I, Lewis M. MoOALLuM,

a citizen of the United. States of America,

residing in the city of Worcester, county of YVorcester, and State of Massachusetts, have invented certaiunew and useful Improvements in Bird-Cage Hooks, off which the following is a specification.

This invention relates to hooks such as are commonly used to support bird cages and the like from a wall.

An object of the invention is to provide a hook of the class described in which strength and rigidity are combined with low cost of manufacture.

Another object is to provide a hook which is readily attachableand detachable from its support.

In general, my device comprises a hook formed from a single piece of wire which is bent to form a horizontal rearwardly extending arm, and another rearwardly extending arm inclined thereto. Each of these arms has a vertically bent end which engages in a socket member attached to the wall. This socket member comprises a plate suitably formed with a socket portion by a single stamping operation. In engagement with each arm of the hook is a strut member which is slidable along the arms in one direction to remove the bent ends from the socket member and in the other direction to retain the ends in the socket member.

My device thus comprisesonly three parts, each of which can be formed by a very simple operation] The socket member may be struck up from sheet metal at a single operation. The hook and strut are formed of wire and the only operation necessary in their manufacture in simple bending. Thus the individual parts of my device lend themselves readily to low cost of production.

The entire device, when manufactured in quantities may be sold for a few cents as against the more elaborate and higher priced articles in use heretofore.

In the accompanying drawings: Figure l is a side elevational view of my improved hook assembled in the socket member; Fig. 2 is a sectional view taken on the line 22 of Fig. 1 looking in the direction of the arrows; Fig. 3 is a rear elevational view of the socket member; Fig. 4 is a sectional plan view taken on the line 4 4 of Fig. 3.

Referring to the drawings in detail: 1 repshape shown in Figs. 2 and 8.

resents flat plate of sheet metalor other I suitable material which is formed in the plate 1 is below the and vertically arranged on this a socket portion 2 and above and Centrally latter are screw holes 31whereb'y. the plate 7 maybe attached to a wall. The socket 2 as well as the holes 3 maybe formedat a single operation. Thus the portion 2 may be struck up by stamping at the same time that the holes '3 are being punched and the plateitself is beingformedin the contour shown. It will be seen that the operation necessary to formthe plate 1 and socket 2 is a very simple one. I a V The hook, as heretofore mentioned, is made up from a single piece of wire. This wire is bent as follows: Starting from a short vertical end 9,-the wireis-bent perpendicularly to form a horizontal arm 4 which may eXtendIto any suitable or'desired distance. I The wire is then bent downwardly and'a semi-circular portionw5 is thereafter formedafter which the wire is brought upwardly and bent'backwardly upon itself at 6. The wire is then brought around in contact with the semi-circular portion 5 serv ing to strengthen the hook portion formed thereby. Finally the wire is brought rear wardly in inclined relation to the portion 4 as shown at 7 and is formed at its end with a short'upturned vertical end 8.

The ends 8 and are in vertical alinement i the

wires

4 and 7 respectively and the member 10 is slidable along these wires in either direction. Thus by sliding the member 10 to the left as viewed in Fig. 1, the ends 8 and 9 are positively forced in the socket and are thereafter retained in this position due to the frictional engagement of the eyes '11 and 12, with the

portions

4 and 7 of the.

hook. By moving the element 10to the right it'will be seen that the

portions

4 and 7 are spread apart with the point 6 acting as a pivot point. This action continued will remove the ends 8 and 9 from the socket 2.

It is to be noted that the member 10 has in addition to its functions above outlined, the effect of a' strut. The member 10 conn'ects the portions e and 7 and ties the same together, thus effectually bracing the structure. The inclined portion 7 is arranged to take the. thrust due toa weight on the hook 5 and transmit the latter to the wall plate 1. The entire hook is arranged to produce a strong and rigid hook with the greatest economy of material.

Thus, I have provided a simple strong and rigid hook which may be produced at aminimum cost with a maximum economy in material. Y i

It isunderstood that many modifications may be made in the structure disclosed With outdeparting from the scope of my invention which is defined in the appended claims.

What I claim is: y

1. A hook for bird cages and the like, comprising in combination, a wall plate adapted to besecured to a wall, a struck up socket portion thereon, a horizontal arm, another arm inclined to said horizontal arm, bent portions on each of said arms adapted to engage in said socket, the outer portions of said armsbeing bent to form a hook, said arms, hook and bent portions being integral parts of a single wire, and a strut member connecting said arms and movable thereon to serve to retain the bent portions in the sockets of the wall-plate.

2. A hook for bird cages and the like, com- Copies of this patent'may beobtained for five cents prising in combination, a wall plate, having a single integrally formed socket portion thereon, a hook member, detachably supported in said socket portion, said member comprising a horizontal outwardly extending arm, an arm inclined thereto, a hook portion, and vertically disposed bent portions on each of said arms arranged to engage in said socket portion, said arms, hook and bent portions being integral portions oi a single wire, and'a member connecting said horizontal and inclined arms and slidable thereon, said member adapted when moved in one direction to hold said bent portions in said'socket and when moved in the other direction to remove said portions therefrom.

3. A bird cage hook and support therefor, comprising in combination, a wall-plate formed with centrally arranged struck-up portion to provide an opening therethrough, a hook proper formed from a' single piece of wire, one end having a cage-engaging portion andi'ts opposite end bent into angular portions to engage the top and bottom part of the struck-up portion, and means oomprising a slidable bar to retain the angular portionsin place in the struck-up portion of the Wall-plate and to furnish means to brace the members of the hook, as described.
