ADJUSTABLE BRACKET.

" Application led October 16,

To all whom-it ma'y concern.'

Be it known that I, ENGELBERT J Voor, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and Stateof Michigan, have invented certain new' and useful Improvements in Adjustable Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to adjustable brackets made of metal and the support therefor, it being the object and purpose o` the pres'- ent invention to provide brackets of this character with various new and useful fea f tures of constructionresulting in novel and meritorious functions as will be more clearly apparent from the description of the embodiments shown in the accompanying drawings, in which;

' Figure 'l'. is Va perspective yiew of the bracket.

Fig. 2 is a side elevation of the bracket connected to the support therefor.

Fi 3 is' a section taken' on the line 3,-3 of Fig. 2, looking in the direction indicated by the arrows.

. Fig. 4 is a rear elevation of the bracket support, one bracket being connected thereto. l

Fig. 5 is a perspective view' ofa detail of the screw'threaded stud forming an element of the construction; and

Fig. 6 is, a" pers ective view of a slight modification in t e construction of the bracket.

end of t Like reference parts `throughout drawings.

The racket includes in its construction a horizontal bar 1 which at one end is turned downwardly at rightan les to form an extension 2, the other end ein turned in the opposite direction and forming ashort lip 3. A brace 4 lies between the horizontal and vertical arts 1 and 2 of the bracket., One

lie brace is screw 1t readed and ex' tends throughthe extension. at 5 projecting a short distance lbeyond the rear surface of said extension. A nut 6 is threaded on to the brace and'bears against the front face of the extension 2 asI fully shown in Figs.1 and 2.

The sup ort for the bracket on which it may be a )ustably mounted is of channel characters refer"' to like the several views of the 2 as indicated Specication of Letters Intent.

191e'. serial No. 125,983. iron construction having a web 7 and two rearwardly extending flanges a pluralityl of key-hole slots 9 are cut. al distance above the end 5 ofthe rod 4 a screw threaded stud 10 .passes through the extension 2A of the bracket, ithaving a' head- 11 lying back of' said extension and being rooved throughout substantially its entire length as shown at' 12. The opening in the extension through which this stud passes. is of circular outline except that a projection 13 extends into said opening from one side and is of lsuch .formation that it fitsthe groove 12 in the studv 10. A nut 14; is threaded' on the stud. A short distance above the stud a portion of the part 2 of thebracket is struck outwardly forming the lug 15. stud 10 is the vertical distance from the top of a keyhole slot 9 and it is apparent thatA when the head 11 is inserted in the upper enlarged portion of a slot 9 and then dropped downwardly so that the shank of the narrow lower portion of "the saidl slot, the lug 15 passes within the-slot and is closely adjacent to the upper boundary of the slot. The nut 14 may then be tightened to retain the bracket in position lon the support. It may also be noted tha't the end 5 of the brace Llis located with reference to the stud 10 such that when the bracket is attached to its support'with thel stud seated in'the lowermost part of oney keyhole slot 9 the end 5 will enter the similar portion of the slot 9 next below. In practice after `the stud-10 has been passed through the extension 2 and the nut 14 turned thereon, the end of the 8. In the web v so l' the stud rests in` stud is enlarged making what is known as a staked bolt, so that the nut cannot llose from the stud in transportation. Furthermore it .intended to place at the tal portions 1 of the'brac'ket, a clip 17. of metal which .is securely fastened and turns around thellip 3 as shown in Fig. 2, serving to hold a" she f placed on the bracket from movementoutwardly'. Normally the lip 3 is suilicient to prohibit this movement,V but at end of the horizon--- timesthe front-.edge of a shelf may be raised ion horizontal portion 1", a vertical portion 2Il opening for the passage of the stud 11 having a projection 13a lsimilar to the projection 13 heretofore described and a lug 15 similar to the lug 15 described in connection with the bracket shown in Fig. 1 are formed in the vertical portions 2'* of the bracket. This suliicient to withdraw the bracket can be connected in a manner similar to that described with reference to the bracket shown in Fig. 2 except that the end of a brace rod is not inserted in a keyhole slot 9. The lug 15 `preferably is enlarged at its upper end and formed to lit in the keyhole slot 9 having lateral projections as shown in Fig. 6 which prevent any turning movement of the bracket with reference to the support.

From the foregoing it will be apparent that II have provided a bracket of very simple construction and one serving many useful functions; By use of the lug 15, and especially with that modification thereof shown in Fig. 6, the brace rod is eliminated and the bracket is held against turning movement with respect to its support the same as if the brace rod `heretofore used was present. Also heretofore if the nut 14 should become loosened it was very easy to elevate the bracket and disconnect it from the slots in the support therefor. In the present construction the lug 15 serves as a stop against this upward movement which cannot occur unless the nut 14 is loosened lug 15 from a slot 9. Furthermore the rooved stud and the projection on the braclet coacting therewith holds'the stud against turning when it is de sired to operate the nut 14 thereof and the staked character of the stud is-an insurance against loss of the securing nutsv 14 when the brackets are shipped.V

I claim :4-

1. In combinatioma supporting bar pro- I Ivided'with keyhole slots, a bracket consisting of a bar bent to form outwardly extending and vertical arms, a iheaded stud attached to the vertical arm and a lu struck from the vertical arm above the headlad stud, the rear of said arm and both being received within a single keyhole slot on the supporting bar, substantially as described.

" staked to prevent removal .theretlirou gh with a 2. In combination, a supporting bar provided with slots, each having a relatively narrow lower ortion anda wider upper portion, a brac {et comprised of abar bent to form outwardly extending and vertical arms, a headed stud. attached to the vertical arm, and a lug projecting from and secured to the vertical arm above the stud, both the head of said stud and lug extending to the rear of said vertical arm and both being received within a single slot in the supporting bar, with said head seated back of the narrower portion of the slot and they lug at its upper end lilling substantially 'the upper portion of the slot, substantially as described.

3. In combination, a bracket comprised of a bar bent to form horizontal and vertical arms, said vertical arm having an opening therethrough with a projection extending into the opening, a headed and screwthreadedstud having a roove throughout its length inserted throug the op'ening with the projection inserted in the groove, and a nut on the end of the stud, substantially as described. i 4. In combination, a bracket comprised of a bar bent to form horizontal and vertical arms, said vertical arm having an opening therethrough with a projection extending into the opening, a headed and screwthreaded stud having a groove formed lengthwise thereof inserted through the opening with the projection received in the groove, and a nut threaded on the stud, said stud after placing the nut thereon being of the nut, sub stantially as described.

5. In combination, a bracket comprised of a bar bent to form horizontal and vertical arms, said vertical arm having an opening projection extending into the opening, a headed and screwthreaded stud having a groove lengthwise thereof inserted through the opening with the projection received in the groove, a nut threaded on the stud, said stud after placing the nut thereon being staked to prevent removal of the nut, a lug struck from the vertical arm above the stud, a lip turned u'pwardly from the end of the horizontal arm, and a clip secured to said horizontal arm having a horizontal ortion extending backward over the lip, substantially as described.

In testimony whereof I aiix my signature.
