Abstract
Abstract This bracket is adjustable to various angles above and below horizontal, in equal increments. Double movement is required for adjustment. This is a safety feature for preventing accidental movement of the bracket when used in support of shelving. There are no removable pins, and loosening of screws is not required for adjustment of the angle of the bracket. One person can make the adjustment. The ratchet design of the adjustable bracket provides secure locking thereof. No right and left hand brackets are required.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
130 words
An adjustable shelf bracket comprising, a rear bracket member, a front bracket member movably and nonremovably mounted in said rear bracket member, and means to releasably and selectively retain said rear bracket member in a plurality of angular positions relative to said rear bracket member, a pair of spaced pin members attached to one of said bracket members, and said other bracket member Having a pair of spaced closed slots slidably receiving said pin members, respectively, one of said slots slidably receiving said pin members, respectively, one of said slots being L-shaped and having a longitudinal portion from an end of which a transverse portion extends upwardly, and the other of said slots comprises a ratchet slot having a curved portion from which a plurality of ratchet slot portions extend.
Claim 2
Dependent Claim
130 words
An adjustable shelf bracket comprising, a rear bracket member, a front bracket member movably and nonremovably mounted in said rear bracket member, and means to releasably and selectively retain said rear bracket member in a plurality of angular positions relative to said rear bracket member, a pair of spaced pin members attached to one of said bracket members, and said other bracket member Having a pair of spaced closed slots slidably receiving said pin members, respectively, one of said slots slidably receiving said pin members, respectively, one of said slots being L-shaped and having a longitudinal portion from an end of which a transverse portion extends upwardly, and the other of said slots comprises a ratchet slot having a curved portion from which a plurality of ratchet slot portions extend.
Claim 3
Dependent Claim
37 words
The combination of claim 1, said longitudinal portion of said L-shaped slot extending rearwardly from said upwardly extending portion of said L-shaped slot, said ratchet slot portions extending forwardly of said curved portion of said ratchet slot.
Claim 4
Dependent Claim
17 words
The combination of claim 2, said ratchet slot portions being disposed at different angles one to another.
Claim 5
Dependent Claim
58 words
The combination of claim 3, said pin member in said L-shaped slot of said front bracket member, being slidable in said transverse and longitudinal portions of said L-shaped slot, and said pin member in the ratchet slot of said front bracket member being slidable in said curved portion and in said ratchet slot portions of said ratchet slot.
Claim 6
Dependent Claim
78 words
The combination of claim 4, said pin members being so spaced on said one of said bracket members, and said upper end of said transverse slot portion of said L-shaped slot and the inner ends of said ratchet slot portions being so located that when one pin member is at the upper end of said transverse portion of said one slot, said other pin member may be selectively located at the inner ends of said ratchet slot portions.
Claim 7
Dependent Claim
69 words
The combination of claim 5, the rear end of said longitudinal slot portion of said L-shaped slot and the curved slot portion of said ratchet slot, being so arranged that when said one pin member is at said rear end of said longitudinal slot portion, said other bracket member can be rotated about said one pin member and said other pin member will move through said curved slot portion.
Claim 8
Dependent Claim
85 words
The combination of claim 6, said rear end of said longitudinal portion of said L-shaped slot being a semicircle, said upper end of said upwardly extending portion of said L-shaped slot being a semicircle, said forward ends of said ratchet slot portions being semicircles, the radii from the axis of the semicircle at the upper end of said upwardly extending slot portion to the axes of the semicircles at the forward ends of said ratchet slot portions being equal in length and equiangularly spaced apart.
Claim 9
Dependent Claim
32 words
The combination of claim 7, said ratchet slot portions being separated by fingers, the outer edge of said curved slot portion having a scalloped edge section extending around each of said fingers.
Claim 10
Dependent Claim
56 words
The combination of claim 7, a line passing through the axis of the semicircle at the upper end of the upwardly extending slot portion of said L-shaped slot, and through the axis of the semicircular edge, at an end of one of said ratchet slot portions being parallel to the longitudinal portion of said L-shaped slot.
Claim 11
Dependent Claim
19 words
The combination of claim 9, and also to upper and lower edges of another of said ratchet slot portions.
Claim 12

23 words
The combination of claim 3, and being of progressively increasing length from the upper to the lower end of said curved slot portion.
Claim 13
Dependent Claim
26 words
The combination of claim 10, said ratchet slot portions being of progressively increasing length from the upper to the lower end of said curved slot portion.
Claim 14
Dependent Claim
34 words
The combination of claim 7, one of said ratchet slot portions being inclined downwardly and forwardly to said line, and another of said ratchet slot portions being inclined upwardly and forwardly to said line.
