The present invention is concerned with various improvements in the construction of. bracket shown in United Sta-tes Patent No. 941,682, issued November 30, 1909 and has for its primary obj ect and purpose the application of various improvements to the bracket shown in said patent, whereby it is more stable in its connection to its support and is less liable to become disconnected therefrom should the attaching or clamping bolt used be nottightened as fully as it should be, or if it becomes loosened after it has been once tightened.
`The invention which I have made is fully described in the following description, taken in connection with the accompanying draw-` ing, in which,
Fig. 1 is a perspective view of the improved adjustable bracket of my invention attached to a support.
Fig. 2 is a fragmentary side elevation with parts broken away and shown in section,

Like reference characters rei'er to like parts in the different iigures ofthe drawing.
The adjustable bracket of my inventlon is adapted to be supportedon a vertically posi` "tioned channel which preferably has a3 web 1 and rearwardly turned flanges@ and 3. The bracketis to be located at the Jfront side ott the web. A plurality of vertical and equally spaced apartjkey-hole slots are cut through the web, each having an upper enlarged sub- 3, 1929. serial No. 390,129.
stantially circular portion 4 and a lower narrowed portion 5, as shown.
In the construction oi the bracket, a bracket l arm 6 is used made of iat metal, the outeriree end of which may be equipped with an upwardly extending self-retaining lip 7'. rit its Vrear end saidarin is considerably widened;`
vertically and it has an opening 8 therethrough near its rear end with an opening of less width extending from the rear side of the opening 8 `to the rear edge oi' said arm.
The arm 6 at said rear verticaledgeis` also provided with a rearward projection 9 which extends back of the rear edge of the arm a distance equal substantially to the thickness of the web 1 ojf the channel. lts height in the form shown is somewhat over One-halfof the distance between the upper and lower end of a key-hole slot described.
At each side of the rear end of the bracket `arrn 6 a metal plate 10 is located and perinanently securedbyrivets which pass through both plates and the arm 6. `Each of said plates at both its upper and lower ends and at its rear edge is formed with outwardly turned lips `11 which are located at right angles to the body of Vthe plate, and the rear sides of all of said lips 11 lie in the 4saine vertical` plane with the rear edge o'f the 6 and the `rear edges of said plates 10. Said plates 10 at theirinner edges are also formed with downwardly andV rearwardly extendingiingers12, which arelocatedone at each side of the projection 9, said projection 9, however, at its upper part extending a. short distance above `the upper portionsoi said ears. Each of thefside plates 10 described, opposite the opening in the bracket arm extending from. the opening S therein to the rear edge thereof, is outwardlyembossed or pressed, als indicated` at Abolt 14, having head 15, passes through the opening or passage made byV said embossings 13 andl into the opening 8: of the bracket arm being there equipped with a clamping nut'l, as shown. Theshank oi thebolt islsubstantially square in cross sec tion so that it is held from turning movement.
llVhen a bracket ofl this character is atw tachedto the verticallchannel supportthe hooks 12 are iirst passedinto one of the key-hole slots in the web 1, and the head a distance equal substantially to the thick- 15 of the bolt entered into the enlarged upper portion 4 of the key-hole slot next above, and then the entire bracket moved downward so that the shank of the bolt is received in the lower portion 5 of the upper slot and the hooks 12 in the lower portion 5 of the lower slot. At the same time the projection 9 extends into the same key-hole slot as that in which 'the hooks are located.
By tightening the clamping nut 16 the bracket is brought securely against the front side of the web 1 and the rear sides of the lips 11 similarly clamped against the web. The bracket is held against any tendency tolateral swinging movement by the lips 11 even though the nut 16 should be thereafter loosened or if it is not properly tightened in the first instance. Also by reason of the projection 9 extending into the lower key- Y hole slot, a loosening of the nut 16 will 'not permit disengagement of the bracket from its support in an upward direction, but the nut will have to be threaded backon the bolt for a considerable distance before the bracket can be elevated and at the same time pulled v outwardly far enough to allow the upper end of the projection 9 to pass by the upper side of the key-hole slot in whichvit is located.
Of course, by loosening the nut 16 and running it out on the bolt a sufficient distance, the bracket can be readily detached and adjusted to a different position on the channel support making use of other key-hole slots in the new attachment. y f
The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming Within their scope.A
I claim:
1. A bracket comprising, a bracket arm of flat metal adapted to be positionedV in a vertical plane, a projection extending from an end of said arm and located between the upper and lower edges of the arm, vertical plates secured one at each side of the arm at said end thereof and having their outer edges flush with the said end of the arm whereby said projection extends beyond theadjacent edges of said plates, and hook members extending from the edges of said plates downwardly and beyond said end of the arm, said hook members being located below the upper end of said projection.
2.. Incombination, a vertical support having a plurality` of vertically spaced apart keyholes therein, a bracket arm having an opening near the upper corner thereof, a bolt extending into said opening Vand projecting,V from the arm and of a shape to engage the sides of the lower portion of a slot, a hook near theV lower part of the arm to engage the next lower slot in the support, and a projection on said arm extending above the hook and away from the adjacent end of the armV ness of the support in which the slots are cut, said projection extending into the same opening with the hook.
In testimony whereof I ailix lny signature.
JOSEPH J. KNPE.
