RAYMOND MANOHA, OF GRAND RAPIDS, MICHIGAN.

SHELF-BRACKET.

SPEQKFICATION forming part of Letters Patent No. 745,873, dated December 1, 1903- Application filed August 21, 1903. Serial No. 170,361. (No model.)

To all whom it ntay concern;

Be it known that I, RAYMOND MANCHA, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Im provements in Shelf-Brackets,ofwhichthe following is a specification.

This invention relates to a new and useful shelf-bracket to be used in connection with show-cases and other places where an adj ustable bracket is used for shelving.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The objects of the invention are, first, to form a cheap and efficient bracket which may be used in connection with key-posts for supporting shelves second, to furnish a bracket which will contain the greatest amount of strength and rigidity to the least amount of material; third, to furnish a bracket that can be attached and detached to and from a supporting-post by means of a clip, as hereinafter described. These objects I accomplish by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 shows a perspective view of a shelfbracket constructed in accordance with my invention when applied to a keyhole back post. Fig. 2 shows a perspective view of the bracket detached from the post and without the means of attaching the same thereto. Fig. 3 shows my preferred form of clip used in connection with the bolt for attaching the bracket to the key-post. shows a perspective view of the bracket, showing the end of the bracket which comes in contact with the key-post. Fig. 5 shows a modified form of clip.

Similarlettersrefertosimilarpartsthroughout the several views.

A represents the bracket proper, which is provided with a straight or horizontal upper portion for receiving the shelf, a brace or lower portion made integral with the upper portion, and an upright portion which comes in contact with the key-post. The upright portion is formed of two sections suitably separated from each other, so as to form an open space E to permit of the passage of a bolt, to be hereinafter referred to.

C shows a projection or stud upon the lower part of the bracket which engages with one of the keyholes in the post.

D and D show my preferred form of finishing the end of the bracket which comes in contact with the key-post, such portions D and D being made integral with the bracket and adapted to lie flat against the post when the bracket is applied.

K shows my preferred form of clip provided with a hole E. The clip K is placed over the slot B, and the bolt F passes through the slot and through the opening E of the clip and is provided with a nut which engages with the bolt F for tightening the same. The bolt F is provided with an enlarged head for engaging with the keyholes in the post P. The post P is provided with a series of holes constructed of suitable form for receiving the head of the bolt F and forretaining the same in the holes. These holes are usually called keyholes, although they may be of any suitable form for receiving and retaining the bolts. The end of the bolt farthest from the keyhole post P is provided with a screwthread, with which engages a nut of any suitable form. In the drawings I have shown a wing-nut H; but it will be understood that other forms of nuts may be used for that purpose.

The function of the clip K is to retain the boltin position and to furnish a bearing for the nut H, and the principal object of this construction is to enable me to form the bracket out of thin sheet metal, such as steel or other material, and to protect the bolt and retain the same in place when it is used in attaching the bracket to the post. when such bracket is secured to the post, the projection C engages with the keyhole below the keyhole with which the bolt F engages, the bolt F is drawn down, drawing the bracket in close contact with the key-post P and the flat projections D and D being pressed against the post, giving great strength and rigidity to the attachment.

. In Fig. 5, J shows a modified form of clip. 'When this form of clip is used, it lies in eX- actly the same form as the clip K. It differs from the clip K in having flanges, so as to give a greater bearing on the post. I

In constructing a shelf-bracket out of thin material the material is not thick enough to allow for a hole through which the bolt can pass; but by using my clip, accompanied by the bolt, I am enabled to construct a strong and durable bracket,presentin g a neat appearance, and also to construct a bracket which may be made very cheaply.

The clip secures the bolt in place and gives as great rigidity to the attachment as is contained ina much thickerbracket,where a hole is used instead of the slot B.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is

1. In combination with key-post, a bracket provided with a shelf-support, a brace-like portion, and an upright portion formed of two sections suitably spaced apart, a clip inclosin g the space between the sections which form the upright portion, a bolt extending through said clip and the space between said sections and engaging in said post,and means for tightening the bolt and drawing the bracket in close contact with the key-post.

53. In combination with a post provided with openings, a'bracket comprising a shelf-support, a brace, an upright portion provided with a passage and a projection engaging in oneof the openings in the post, a clip inclosing said passage, a bolt extending through the clip and said passage and provided with an enlarged head engaging in one of the openings of the post, and a nut mounted upon the bolt and adapted to tighten the bolt and draw the bracket in close proximity to the post.

8. In combination with a post provided with a plurality of openings, a bracket consisting of a shelf-support, a brace, an upright portion having a passage, bearing-pieces, and a projection engaging in one of said openings, a clip inclosing said passage, a bolt extending through said clip and passage and having an enlarged head engaging-in one of said openings of the post, and a nut mounted upon the bolt for securing the bracket in close proximity to the post. In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
