Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed January 18, 1906. Serial lrl'o. 296,729.

T0 at whom it may concern:

Be it known that I, Gnono HEINRICH DORKEN, residing in the city of Gevelsberg, West halia, Empire of Germany, the mperor ofGermany, have invented a new and useful Improvement in Brackets, of flange 1 is bent which the following is a specification.

My invention has reference to brackets and it consists in the production of a neat, strong, and cheap bracket formed from a single blank of sheet metal.

My new bracket is shown on the accompanying drawings, in which- Figure 1 is a side view of the complete bracket. Fig. 2 is a front view. Fig. 3-shows the blank. Fig. 4 shows the blank partly bent. Fig. 5 is a vertical section through Fig. 6 is a top view of Fig. 3. Fig. 7 is a top view of Fig. 4. Fig. 8 is a top view of Fig. 5.

Like characters of parts in the drawings.

As shown in Fig. 3, I form my new bracket from a single blank cut out of a sheet of metal, and this blank consists of the brace a, the horizontal arm b, and the back 0. The latter is provided with an upright tongue d. In order to form the bracket from the blank shown in Fig. 3, the brace a is first bent rectangularl y to the back 0 on the dotted line 2 2, as shown in Fig. 4, and then the horizontal arm is bent rectangularly down on the dotted line 2 a, so that the blank has obtained the form shown in Fig. 7. The orti on c and the flange 4 are then bent bac about one hundred an dotted line 1" 1", after which operation the flange 3 is doubled by the material of the portion 0 and the brace is placed reference indicate like asubject of l pleted. Now the tongue in the middle of the same. The flange 4 is then bent on the dotted line 3 3 down on the portion 0, and by this process the back is comd is bent down on the horizontal arm I), then the portion 1) with about'one hundred and eighty degrees on the dotted line so :0 down on the flange 2, which remains in the position shown in Fig. 4, and finally flange 1 is bent on the dotted line 0 0 inwardly and onto the portion 1), which together with the flange 1 embraces the tongue (1. so that the back and horizontal arm are firmly connected together. The back 0 may be formed with holes or slots k for fastening the bracket to the wall, and the brace amay be provided with holes of any form to produce any pleasing design, or the brace a may be pressed in any desired pattern.

My new bracket has the great advantage that no rivets are necessary for holding the parts together, bending process from a single blank, and this is done preferably by special machines.

What I desire to secure by Letters Patent 1s A bracket comprising a wall-plate having inwardly-bent side flanges and a tongue at its top, a horizontal arm having inwardly-bent side flanges which embrace said tongue, and a brace supporting the arm and bearing against the wall-plate, the whole being integrally formed from a single metal blank.
