SHEET-IVI ETAL. SHELF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 581,980, dated May 4, 1897'. Application ned December 11,1393. serai No. 493.380. (No man i To a/ZZ whom, t may concern:

Be it known that I, THOMAS ConscADnN, of New Britain, in the county of Hartford and State of Connecticut, have invented a new Improvement in SheetaMetal Shelf-Brackets and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure l., a View in side elevation of one form which a shelf-bracket constructed in accordance with my invention may assume; Fig. 2, a view in front elevation Fig. 8, a plan view.

My invention relates to an improvement in sheet-metal shelf-brackets, the object being to produce a cheap and strong bracket of attractive appearance with the least expenditure of material and labor.

With these ends in view my invention con sists in a sheet-metal shelf-bracket composed of three non-integral elements-namely, wall and shelf plates, ribs, and a brace-all of the said elements being adapted to be secured together in the manner shown and described.

As shown in the drawings, the wall-plate and the shelf-plate AQ forming one element of the bracket, are formed from a single strip of sheet metal bent transversely a little to one side of its longitudinal center, the wallplate A having countersunk perforations d for the attachment of the bracket to the wall, and the shelf-plate having corresponding perforations a for the attachment of the shelf to it. The ribs B and B of the bracket form another element thereof. As herein shown, they are made independent of each other, their meeting ends being mitered together on the line h. If desired, however, the two ribs may be made integral with each other, but

that construction is not so economical of material, as there is some waste in cutting out the ribs in that way. In 'case the ribs are made integral the wall and shelf plates might be made non-integral and locked together at their meeting ends or simply abutted. The rib B is constructed, as shown, with three lugs Z9', which are passed through corresponding lug-openings a2, formed in the wall-plate A, the outer ends of the said lugs being headed down, whereby the rib B is rigidly secured to the inner face of the wall-plate at a right: an-

gle thereto. The rib B is furnished with three lugs h2 b2 h2, which are passed through corresponding lug-openings a3 CL3 a3, formed in the shelf-plate, the outer ends of the said lugs being headed down to rigidly secure the 6o rib B to the shelf-plate.

The other element of my improved bracket is a brace C, longitudinally bowed and having its ends rigidly connected with the respective ribs B and B', for which purpose 65 each of the said ends is constructed with an undercut lug C', adapted to take into corresponding undercut slots B2 B2, formed in the respective ribs with which the ends of the brace are thus interlocked. y

To bind the ends of the brace to the ribs against lateral displacement,I employ two transverse pins D D, each of which is furnished at each end with a washer E. The said pins are passed through the ribs and the lugs The washers are held 8o tion herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

A bracket constructed in accordance with my invention is very easy to assemble and 9o economical of metal, as there is very little waste in cutting out parts of the shape called for. When made, it is stiff and effective and presents a tasteful appearance.

I am aware that sheet-metal brackets are old, that it is old to form a wall and shelf plate from a continuous strip of metal, and that cast-metal brackets having three members or elements are old, and I do not claim any of those constructions broadly; but,

IOO

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a sheet-metal bracket, the combination with wall and shelf plates Constructed with 1ugopenings, of sheet-metal ribs formed independent of the said wall and shelf plates and constructed with integral, outwardlyprojeeting lugs arranged in correspondence with the said lu:,r-OpeI1in ;siny the plates, to which the ribs are rigidly secured by upsetting the outer ends of the said lugs; a brace made independent of the said Wall and shelf plates and the ribs, and having,` its outer ends secured to the ribs, and transverse pins and washers applied to the ends of the brace and to the ribs, for holding the ends of the former against lateral displacement, the said pins and washers being independent of the wall and shelf plates.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

THOMAS CORSCADEN.
