BRACKET..

Specification of Letters Patent.

Patented Nov. 14, 1905.

To all whom it may concern;

Beit known that I, CARL SOHRAUBSTADTER, a citizen of the United States, and a resident of the city of St. Louis, and State of Missouri, have invented a new and useful Improvement in Brackets, of which the following is a specification.

My invention relates to brackets, and especially to brackets for type-cabinets, portfoliocabinets, and the like.

It has for its principal objects to provide a folding bracket which will move laterally as it is raised and lowered, to provide a laterally-movable folding bracket which will be simple and can be cheaply manufactured, to provide a bracket for cabinets which will be out of the path of the drawers thereof when it is raised and will be in position to support to be used. Fig. 3 is a fragmentary side View of the cabinet and bracket, the bracket-arm being shown in its raised position in full lines and in its lowered position in dotted lines. Fig. 4 is a plan view, on an enlarged scale, of the bracket, the arm being in its lowered position. Fig. 5 is a side view of the bracket, a portion only of the arm being shown in its lowered position. Fig. 6 is a vertical central sectional view through the base of the bracket, the arm being removed. Fig. 7 is a View similar to Fig. 6, a fragment of the arm being in place in its lowered position. Fig. 8 is a perspective view of a fragment of the arm, showing the laterally-projecting cams thereon. ig. 9 is a front view of a modilication of the bracket, a fragment of the arm being shown in its lowered position. Fig. l0 is a view similar to Fig. 9, the arm being shown in its raised position; and Figs. l1 and 12 are plan views of the modified bracket in the positions shown in Figs. 9 and 10, respectively.

In high cabinets of drawers-such, for example, as type-case cabinets, portfolio-cabinets, and the like-the upper cases or drawers are up so high and the lower cases or drawers are down so low that they cannot be used conveniently. Hence it is desirable to remove the inaccessible cases or drawers from the cabinet when they are to be used and to put them in a position convenient for use. The brackets herein described are intended for attachment to cabinets at a convenient height from the ioor to aford a rest upon which the cases or drawers can be placed when in use. The brackets will necessarily project in front of the cabinets. l/Vhen they are not in use, it is desirable to have them out ofthe way. Hence the brackets are made to fold up so as to raise the arms thereof. The brackets must have ledges or flanges projecting inwardly beyond the sides of the cases or drawers in order to support the latter. If the brackets were folded straight up,tliese ledges or flanges would project into the path of adjacent drawers. To avoid this,the brackets are so constructed that the arms will move laterally as they are raised, and they are thus carried out of the path of the cases or drawers in the cabinet.

The bracket comprises a base l to be secured to a cabinet and an arm 2. The base 1 comprises a portion L-shaped in plan and is thus adapted to embrace the corner of a cabinet. While this is the preferred form, it is obvious that the base might comprise a fiat plate simply. Ears 3 4 extend forwardly from the L-shaped portion. The ear 3 on the side toward the drawers or cases will be spoken of as the inner ear and the ear 4 will be spoken of as the "outer ear. The arm 2 is pivoted between said ears 3 4, being carried on a screw 5, which passes through one ear and has screw-threaded engagement with the other ear. Of course a pin could be riveted in the ears and would serve the same purpose; but the construction shown is preferred, as thedbracket is easily assembled and disassemble The inner ear 3 is provided with two lateral projections 6 7, arcuate in plan and terminating in inclined surfaces. The upper projection-6 has an angular extent of a little less than `ninety degrees, begins near the vertical line passing through the center of the screw 5 and extends downwardly and rear IOO IOS

wardly, the inclined surface of the projection receding from the ear from the front upper end to the lower rear end. The lower projection 7 is diametrically opposite the upper projection 6 and is similar to it. It has an angular extent of about ninety degrees, begins near the vertical line passing through the screw 5 and extends upwardly and forwardly, the inclined surface receding from the ear from the lower rear end to the front upper end.

The arm 2 has a substantially circular head 8, through which the screw 5 passes. Annularfrecesses 6a 7 a, capable of receiving the projections 6 7 on the ear 3, are provided at the periphery of said head. Concentric with such recesses and lying between them projections 9 1() are provided on the face of the head 8 opposite the ear 3. These projections are similar to the projections 6 7 on the ear 3. The outer ear 4 is provided with annular recesses 9a 10a opposite the projections 6 7 on the ear 3 and have a sufficient extent to receive the projections 9 10 on the arm 2.

The arm 2 is L-shaped in cross-section, having an inner lateral flange 11, upon which the cases or drawers may rest when in use.

The parts are preferably made of malleable castings and assembled without machining. To prevent any wabbling due to inaccuracy of the castings, when the arm is in its raised position a lug 12 is provided on the base of the bracket. The upper iiange of the arm will rest against said lug 12 when the arm is raised and will be laterally supported thereby.

The operation of the bracket will now be described.

Assume that the arm is in its raised position, as shown in Fig. 1. The projections 9 10 now lie in the annular recesses of the ear 4 of the base. When the arm is pulled down, the projections 9 y1() will engage the front and rear edges of such recesses, respectively, and thus the arm will be forced to move laterally and inwardly as it turns upon its pivot. The

walls of the recesses engaged by the projections are beveled to secure a smooth working' of the parts. As the arm moves downwardly and laterally the projections 6 7 on the ear 3 enter the annular recesses of the head 8 of the arm. When the arm 2 reaches a horizontal position, the front and rear walls of the recesses respectively strike the shoulder formed by lower and upper ends of the projections 6 7, respectively, as indicated in Fig. 7. The arm is thus firmly supported in its horizontal position. When the arm is raised from the horizontal position, the head 8 thereof rides upon the inclined surface of the projections 6 7 on the ear 3, and the arm is thus moved laterally and outwardly. Vhen the arms are in their horizontal positions, .the inner faces of their vertical ianges are far enough apart to admit a type case or drawer between them, while their horizontal or lateral flanges are in position to support the same. 'When the arms are raised, the inner edges of their lateral anges are far enough apart to permit a type case or drawer to pass between them.

A modified bracket serving the same general purpose as the preferredgbracket described above is illustrated in Figs. 9 to 12. The base 13 has an L-shaped portion from which ears -14 15 project forwardly. These ears are so shaped as to support a pivot-pin or screw 16 in an inclined position in a horizontal plane. An arm 17 is pivoted upon said inclined pivotpin or screw 16. The arm is so shaped that when it lies in a horizontal position the major portion of it will be perpendicular to the front of the cabinet. When the arm is raised. it will be caused to swing out of the path of the drawers or cases in the cabinet on account of the inclination of the pivot.

Obviously my device is capable of considerable modification within the scope of my invention, and therefore I do not wish to be limited to the specific construction shown and described.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A bracket comprisinga base, an arm pivoted on said base to turn about a substantially horizontal axis, and means to move said arm laterally as it moves pivotally, said means being arranged to hold said arm at one of the extreme positions assumed during its lateral movement while said arm occupies either eX- treme of its pivotal movement.

2. A bracket comprising a base having forwardly-projecting ears, a substantially horizontal pivot mounted in said ears, an arm on said pivot, projections on the inner side of one of said ears arranged to bear on said arm, the bearing-surfaces of said projections being inclined, and projections on said arm arranged to bear upon the other of said ears, the bearing-surfaces of said projections being inclined, whereby said arm will be caused to move laterally as it moves pivotally and said lateral movement is limited in both directions.

3. A folding bracket comprising abase, an arm pivotally mounted on said base, means to cause said arm to move laterally as it moves pivotally, and a stop on said base to support said arm when it is folded up.

L1. A bracket comprising a base provided with forwardly-projecting ears, inclined projections on the inner side of one of said ears and each terminating in a shoulder, an arm pivotally mounted between said ears and having recesses arranged to receive said projections and each terminating at one end in a wall arranged to engage one of said shoulders when said arm is in its lowermost position.

'5. The combination of a cabinet, drawers therein, and folding brackets secured to the opposite sides of said cabinet and comprising arms pivotally mounted to turn about a substantially horizontal axis and arranged to sup- IOO ISO

port any one of said drawers when in their lowermost position and to swing out of the path of said drawers when raised.

6. The combination of a cabinet, drawers therein, and brackets secured to the opposite sides of said cabinet and comprising arms pivotally mounted to turn about a substantially horizontal axis and provided with flanges, said flanges being arranged to support any one of 10 said drawers when said arms are in their lowermost position and to.be moved out oi' the path of said drawers when raised.
