JOHN CRIDER, OF CONCORDIA, KANSAS.
SPECIFICATION forming part of Letters Patent No. 427,462, dated May 6, 1890'. Application filed September 27,1889. Serial No. 325,270. (No model.)
To aZZ whom, it may concern:
Be it known that 1, JOHN GRIDER, a citizen of the United States, residing at Concordia, in the county of Cloud and State of Kansas, have invented certain new and useful Improvements in Shelf-Brackets; and I do declare the following to be a full, clear, an d exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to brackets and fixtures for the same.
The object of the invention is the con struction of a wall-strip of peculiar conformation at the end of the slot in which the adjusting or tightening bolt works, and a corresponding peculiar formation of the head of the said bolt, whereby it canbe readily'removed and inserted through a narrow cross-slot in the said strip.
A further object of the invention is the prod notion of a single means whereby the bracket can be quickly adjusted up or down, as required, within certain limits, and which when adjusted and tightened or fastened will be as firm as if cast with the strip.
The improvement consists of the novel features which will be hereinafter more fully described and claim ed, and which are shown in the annexed drawings, in which- Figure 1 is a perspective View of my invention. Fig. 2 is a cross-section on theline 00 0c of Fig. 1. Fig. 3 is a cross-section on the line 1 y of Fig. 1. Fig. 4- is a perspective View of the rear end of the bracket. Fig. 5 is a vertical section of the upper end of the strip on the line .2 .2 of Fig. 1, showing the manner of removing the tightening or fastening bolt by dotted lines.
The wall-strip A, of suitable length, has a vertical slot at between its edges, a cross-slot b at the end of slot a, and teeth 0 on each side of said slot (0. The rear side of the strip A is provided with vertical recesses cl on each side of the slot a to give clearance for the head of the fasteningbolt E.
The .bracket F is of ordinary construction, except that it is provided with a lugf at its lower end, which enters slot a and guides and steadies the bracket in its movements, and with an opening f and teeth f contiguous to the said opening, corresponding with the teeth 0 on the strip A, with which they engage to prevent the bracket slipping. The shank or stem of the bolt passes through opening f in the bracket and is provided with the thumbnut G. To adjust the bracket up or down, loosen the thumb-nut G sufficient. to permit the disengagement of the teeth F from the teeth'C. The bracket can now be moved to the required position, and is fastened by retightening the thumb-nut G.
The inner corner on of that portion of the strip A bordering on slot a is beveled, and the corners of the bolt-head are correspondingly beveled, so that the fastening-bolt can be tipped and its head readily inserted or removed through the slot a, as shown by dotted lines in Fig. 5. lVhcn the strip is of considerable length, the slot a is interrupted or extends part way of the strip, having the solid portions N, which receive the screws or nails that fast-en the strip to the wall.
What I do claim as my'invention, and desire to secure by Letters Patent, is-
1'. The combination, with the Wall-strip having slot aand teeth C on each side of the said slot a, and having recess cl on its inner side, of thebracket havingteeth f and a bolt-opening f and the fastening-bolt passing through opening f and slot a and having its head inserted and traveling in the said recess cl, substantially as described.
2. The combination, with the wall-strip having slot a, recess d, and teeth on each side of the said slot, of the bracket having opening f, teeth f contiguous to said opening f, and the fastening-bolt inserted through slot at and openingf and having its head traveling in recess (Z, substantially as set forth.
3. The combination, wit-l1 the 'all-strip havin g slot a, recess cl, and teeth on each side of the slot of the bracket having opening f, teeth f contiguous to said opening, and lug f, the latter traveling in slot a, and the fastening-bolt inserted through opening f and In testimony whereoflaffix my signature in IO slot a and having its head traveling in said presence of two Witnesses. recess (Z, substantially as described.
