3 Claims. (Cl. 248-19) This invention relates generally to a supportindicates the web of a vertical supporting meming device and more particularly to an adjustber, 11 its flanges and 12 the slots or openings able bracket which is adapted to hold shelves which are formed in the web 10. in show cases or in any other relation. A bracket arm 13, see particularly Fig. 5, is

Also, the bracket arm 13 has small in a vertical supporting member whereby sliding projections 15.

Also, a plate member generally, such having a raised portion member is fastened to the flat bracket arm so 17 in which a plurality of slots 18 are formed, as to fricticnally engage against the outer side these slots receiving the hook members 14 and of the supporting member. the small projections 15. The propjections 15 I One of the primary objects of my invention is are headed over as clearly shown at 19 in Fig. 7 to provide a construction wherein the bracket 3 and thus the plate member and the bracket arm may be attached or detached with a simple arm are securely attached together. sliding movement and yet in which the two From an inspection of Fig. 5, it will be seen members will be securely and firmly attached that considerable space exists between the down- 20 together and accidental detachment prevented. ward extension of the hook members 14 and the Another advantage resides in the process of body 13 of the bracket arm, as indicated at 20 manufacturing the bracket arm whereby the and thus the manufacture of this piece of metal hook members may be readily formed inasmuch is easily attained by a punching operation.

In this modification, a supporting strip 29 is provided, the web of this strip being difset rearwardly as indicated at 30 whereby the hooks 14 will properly engage the same. That is, the space between the front edge of the hook members and the outer edges of the'plate member 23 is of "sufficient size as to provide easy manufacture as previously described in connection with the Fig. 10 illustrates a cross sectional view of a supporting strip having a curved web 31 and fianges32, the curved web 31 being utilized siniilarly to the web of the vertical supporting strip as shown in Fig. 9. 77

Having thus? revealed this invention, I claim as new and desire to secure the following come binations and'elements, or equivalents thereof, by Letters Patent of the United States.

I claim: W W

l. A bracket comprising, a bracket arm of flat metal adapted to be positioned in a vertical plane, hook 'members extending horizontally from one end of said' bracket arm, a plate member having openings through which the hook members pass, said plate member having a curved ,cross section, and means for fastening the plate member onto the said bracket arm.

2. A bracket comprising, a bracket arm of flat metal adapted to be positioned in a vertical plane, integrally formed means extending horizontally and then downwardly from said bracket arm, and plate means fastened to the bracket arm iiiteriorly of the downward extensions, said plate member having a curved cross section for the purpose described.

3. In combination, a support provided with spaced slots, a bracket consisting of a fiat arm adapted to be located in the plane of said slots, said fiat arm having hooks extending from one end thereofgisaid hooks being of such size as to extend through said slots and then being adapted to be slid longitudinally of the said support and a plate means rigidly fastened to the bracket arm, said plate means having a portion located at an angle to the support so as ,to cause increased frictional engagement of the upper hook member as the bracket arm is slid longitudinally along the support to its operative position.
