Patented Dec. 6, 1910.

Application filed May 16, 1910. Serial No. 561,591.

To all whom 'it may concern:

Beit known that I, WILLIAM F. FREEMAN, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Adjustable Detachable 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.

My invention relates/to improvements in adjustable detachable brackets, and more particularly to such brackets as are adapted to support shelving in show cases and the like, and its object is to provide means for easily and quickly locking the bracket in its adjusted position, and to provide the device with various new and useful improvements as hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, in which:

Figure l isa perspective view of abraeket embodying my newly invented features; Fig. 2 a perspective view of a holder for the bracket; Fig. 3 an enlarged elevation, partially in section of the bracket and holder in operative and locked position; Fig. 4 a' rear View of Fi 3; and Fig. 5 an elevation showing the ho der in vertlcal section and the bracket with one of the hook lates removed, unlocked and removed om the4 upon and hook over' the lower wall of these openings, leaving 'an o .en space between the top of the hooks an the top wall of the openings.

In order to overcome the possibility of the bracket becoming accidentally unhooked' from the holder, I provide a rearwardly extending lug 5 near the lower angle of the arm 1. When the bracket is lin operative position, this lug 5 projects through one of the openings 4 above the lower hook, engaging the upper wall of said opening and preventing the bracket from being Vraised and unhooked. It Will be seen that in this position, which is shown in Fig. 3, the base of the triangle; or in other words, the rear edge of the bracket arm 1,'engages the face ofthe holder 3, thus securely supporting the arm with its upper edge at right angles to the bar 3. To lock the arm in this position, I provide an o posing slot 7 in the hook plates 2 radial rom the point at which the arm is pivoted, and a corresponding slot 8 1n the arm opposite the slot 7. A slidable pin having a head at each end, slidably' engaging the outer surface of the respect-ive plate, is inserted in these slots and when the pin is at the bottom of the slots pivotal movement of the arm .is prevented. The upper end of the slot 8 in the arm, however, is provided with an extension 8a concentric with the axis of the pivot before mentioned, and when the pin 6 is raised to the'top 0f the slots and 8, the outer end of the arm may be raised. When` this movement takes place, the pin will traverse the slot 8a and the lug 5 will bewithdrawn lfrom the opening 4 1n the holder 3, allowing the bracket openings, plates having hooks adapted to be inserted in said openings, a bracket armv pivoted between said plates, and a lug 5 on the arm to enter one-of said openings andA lock the hook therein.

2. A bracket, comprising a bar havin openings, plates having hooks to enter said o enings, laterally extended flanges on the p ates to engage the bar, av bracket arm .pivoted between the plates, and a lug on the arm adapted to enter one' of said openingsy and lock the hooks in the openings.

3. A bracket, comprising a barl havin openings, plates having hooks to enter sai openings, a bracket arm pivoted near its upper angle between the plates, alug on the los' arm near the lower angle thereof and projected into one of said openings to lock a 'hook therein, and means for locking the bracket arm to the plates'.

4. A bracket, comprising a bar having openings at intervals therein, plates having hooks to enter said openings, a bracket arm pivoted between the plates near its upper angle, a lug on the `arm near its upper angle adapted to enter one of said openin and lock the hook therein, radial slots in t e arm and plates, and a slot in the arm extending ing-hooks to enter said openings, laterally projecting flanges on the plates, a bracket arm pivoted between the plates, a lug on the arm to enter one of said openin s and lock the hook therein, op osing radlal slots in the arm and plates, a ateral slot in the arm communicating with the radial slot in the same, a pin slidable in said slots, and heads 0n the respective ends of .the pin slidably en aging the outer surfaces of said plates.

n testimony whereof I alix my slgnature in presence of two witnesses.
