SHELF-BRACKET.
Application filed. April 13, 1908.
T 0 all whom it may concern:
Be it known that I, J AMES P. MCKINNEY, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Shelf-Brackets; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to shelf brackets, its object being to provide such a bracket in which a brace is formed from a single piece of metal bent in such a manner as to give the maximum strength with a minimum amount of material.
To these ends my invention comprises, generally stated, a brace for a bracket consisting of a single piece of sheet or plate metal, the inner portion of the metal being curved outwardly and then bent over to form a tubular section abutting against the inner faces of the wall plate and shelf plate of the bracket, leaving the outer portion composed of a sin .gle thickness of metal.
In the accom anying drawing Figure 1 1s a side elevation o a bracket with my improved brace applied thereto; Fig. 2 is a vertical section of same with the brace in elevation; Fig. 3 is an end view; Fig. 4 is an elevation of the brace; and Fig. 5 is an enlarged cross section on the line 5-5 Fig. 4.
In the drawing the numeral 2 designates the wall-plate and the numeral 3 the shelf-plate provided with suitable openings for the attachment of the wall-plate to the wall and the shelf-plate to the shelf. The brace 4 is formed of a single piece of sheet or plate metal 4 bowed or curved as indicated, and provided at its opposite ends with the lugs 6 which are adapted to enter openings 7 formed for them in the wall and shelf-plates, said lugs forming rivets by means of which the brace plate is securely held in place. The inner portion of the brace is provided with the tubular portion 8 which is formed by bending the inner portion of the plate. The plate is first bent outwardly to form substantially half of the tubular portion, whereupon the remaining portion of the plate is then bent over close to the opposite side of the flat portion Specification of Letters Patent.

Serial No. 426,760.
of the brace, thereby forming the tubular portion while the main portion of the brace consists of a single thickness of metal. The ends of the tubular portion 8 abut against the inner faces of the wall plate and shelf plate and so add to the strength of the bracket. In this manner I do away with the extra thickness of metal in the brace and thereby reduce the cost while at the same time the brace is made lighter without'in any manner detracting from its strength or rigidity. The tubular portion of the brace acts to strengthen the brace and the metal is forced into close contact with the inner side of the plate so as to adhere closely thereto and all connections in the form of rivets or other devices are avoided.
That I claim is:
1. In a bracket, the combination of a brace comprising a single piece of plate metal, the inner portion of the plate being bent to form a tubular portion abuttin at its ends against the inner faces of the wall plate and shelf )late of the bracket, and the outer portion of said plate being of a single thickness of metal.
2. In a bracket, the combination of a brace comprising a single piece of plate metal, the inner portion of the plate being bent to form a tubular portion abutting at its ends against the inner faces of the wall plate and shelf plate of said bracket, and the free edge of the inner portion corresponding substantially to the line of the bend of the opposite side of the tubular portion.
3. In a bracket, the combination of a brace comprising a single piece of arch-shaped plate metal, the circumferentialportion of the plate being bent to form a tubular portion abut ting against the inner faces of the wall plate and shelf plate, and the outer portion of the plate being of a single thickness of metal.
In testimony whereof, I the said J AMES P. McKINNEY have hereunto set my hand.
