M. KURTZON.
ADJUSTABLE BRACKET.
APPLICATION FILED DEG. 2a, 1912.
1,080,639, Patented Dec. 9, 1913.
MORRIS'KURTZON, or CHICAGO, ILLINOIS.
ADJUSTABLE BRACKET.
To all whom it may concern:
Be it known that I, MORRIS K'Un'rzoN, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Brackets, of which the following is a specification.
This invention relates to improvements in adj ustable brackets of the type used especially in show-cases as supports for glass shelves though it is adapted for other uses where an adjustable horizontally extending arm is desired.
The especial object of the improvements herein. described is to provide adjustable means for connecting the bracket with its supporting bar in which there will be no separable members, thus avoiding the objection to such devices resulting from the loss of nuts, bolts, 01' other detachable members.
A further object of my improvements is to provide locking means for the bracket which will be readily accessible when placed within a show-case and can be manipulated to eli'ect a strong and clear attachment for the bracket, this being of considerable importance in view of the fact that the articles supported by these brackets are often of a highly fragile character and of considerable value, hence if the bracket should break or become loosened from its support, the contents of the shelf supported by the bracket would be broken or damaged.
In the accompanying drawing I have illustrated a preferred adaptation of my invention in the following views z-Figure l is a perspective view of the bracket locked upon its supporting bar; Fig. 2 is a side elevation of a bracket detached from the bar; Fig. 3 is a fragmentary and sectional view of the bar and bracket; Fig. 4 is an enlarged detail of the locking bolt by which the bracket is connected with the bar, and Fig. 5 is an end view of the bolt shown in Fig. 4t.
Referring to the details of the drawing, 6 represents the body of my improved bracket the same being formed of flat sheet metal the inner end of which is bent up at right angles to provide a vertical flange 6* and the outer end of which is cut or notched to provide the shoulder 6 7 represents a sheet metal plate which is welded to the inner portion of the bracket 6 and is bent up at its inner end to form the vertical flange 7 which corresponds to the flange (3 of the bracket 6. The portion of Specification of Letters Patent.
Application filed December 28, 1912.
atented Dec. 9, 1913. Serial No. 739,008.
the bracket member 7 is expanded in semitubular form as shown at 7, and it will be understood that the correspomling portion of the bracket body (3 will be similarly expanded though such does not appear by the drawing. A rectangular opening 7 is cut through the members (5 and 7 to form a socket for the outer end or head of the locking bolt 8. This bolt has inserted in its head a pin 8 which extends radially therefrom and on the inner surface of the head are cut inclined surfaces 8". The shank of the bolt is cylindrical as at 8 and is cut away near its inner end as at 8 to form a circular tongue 8. The cylindrical portion 8" of the bolt passes through the tubular boss formed on the bracket members (3 and 7, and is adapted to partially rotate therein. The outer edge of the tubular boss 7 has its edge inclined as at 7 to correspond with the inclination or shoulders 8 of the head of the bolt 8 so that as the bolt is turned on its longitudinal axis there is a cam like action which serves to draw the bolt outwardly relative to the flanges (3", 7, of the bracket. 9 represents a channel bar in which there are screw holes 9 and key hole slots 9' the latter adapted to receive the tongues 8 of the bolts 8 and the laterally extending lugs 7 of the plates (3 and 7, in a Well known manner.
It will be obvious that upon grasping the pin 8 and turning the bolt 8 on its longitudinal axis so that the longer diameter of the bolt 8 is brought opposite the longer longitudinal diameter of the boss 7" a wedging action will take place which will draw the bolt forwardly and thus cause the tongue 8 and the lug 7 to clamp the rear side of the bar 9 adjacent the slots 9" thus firmly locking the bracket in position.
Heretofore it has been common to mount on bolts, corresponding to the shank and tongue portions of the bolt shown in Fig. 4, and threaded at their outer ends, nuts which are screwed up against bosses similar to the portion 7* of this device. These nuts are necessarily very small and not accessible for operation by wrenches and are diliicult to tighten by the use of the fingers of the operator alone. llurthermore the nuts become lost when the brackets are detached and when the bolts are separated from the brackets.
It will be obvious in my device that after it is made up or assembled the bolts cannot be detached from the brackets nor can the head of the bolt which corresponds in function to the ordinary nut be detached from the bolt. 7
It will be understood that the inner end of the bracket member 6 is formed with a lug which corresponds in all particulars to the lug 7 on the plate 7 It will also be understood that these lugs and the tongue 8 will v be spaced a sufficient distance from the flanges 6 7, to form an easy slideway for the channel bar 9.
Having thus described my invention what I claim as new, is
1. An adjustable bracket comprising an arm having flanges extending at right angles thereto and laterally projecting lugs at lts inner end, and provided withan apertured boss, in combination with a bolt rotatably mounted in said boss and having a tongue at its inner end, and a head at its outer end, said boss and head having co-acting camface portions whereby the rotation of the bolt will cause a longitudinal movement of the bolt, a pin projecting from said head,
and means for supporting said bracket, said means adapted to be clamped by said lugs and tongue. v 2. A bracket consisting of an arm having lateral flanges and lugs at its inner end, and having an apertured boss near said inner end the forward edges of said boss being inclined, a bolt rotatably mounted in said boss and having a head with inclined edges adapted to cooperate with the inclined edge of said boss whereby the rotary movement of the bolt will cause it to move longitudinally relative to said bracket, means for facilitating the rotary movement of said bolt, and said bolt provided with a tongue at its inner end in combination with a supporting bar having apertures adapted to receive said tongue and the lugs on said arm,- substantially as set forth.
In testimony whereof I aflix my signature in the presence of two witnesses.
