UNITED STATES ISAAC A. BAUM, OF CHICAGO, ILLINOIS.

PLASTER TERMINAL.

Application filed September 12, 1927. Serial No. 219,093.

My invention relates to plaster terminals and particularly to a novel one-piece sheet metal terminal.

It is well known that plaster terminals of all kinds and types have been presented to builders, with more or less success. One of the greatest dificulties in the past has been to produce a plaster terminal that will fit snugly over a rough buck, insure rigidity, and accurate alignment.

The device or my invention is intended to overcome all the defects previously encountered in a device of this type. My invention consists of a single piece of sheet metal having a plurality of cars contacting one side of the rough buck, and the other angle contacting the other face of the rough buck. The metal is bent at right angles to the base member and terminates in a backwardly disposed bead that functions not only as a plaster terminal, but also as an anchor for the adjacent plaster.

The device will be more readily understood by reference to the accompanying drawing, in which;

Fig. 1 illustrates a perspective view of a device constructed in accordance with my invention.

Fig. 2 is a similar view of a modified con struction showing the ears cut through the full width.

In the drawing, and referring particularly to Fig. 1, it will be seen that I have illustrated a rough buck, A, door jamb and stop, B, and plaster C. The usual plaster support or lath is not shown. The device of my invention consists in a long, relatively narrow strip of: metal having a base 10, plaster defininn" portion, 11 and plaster bead 12. Formed out of the metal in said base, are the cars 13 which are bent at right angles to the plane of the base 10, on the line 14 at intervals along the length of the strip. The plaster defining portion 11. is formed at right angles to the base 10 on the line 14, and terminates in a longitudinal bead 12 which is bent back on itself to form less than a right angle with the plaster defining portion. This bead serves to strengthen the edge against possible bending by being struck by objects during con struction, as well as to provide a secure anchor for the plaster which fills in behind it. The base 10 and the ears 13 are intended to contact the narrow and the wide faces respectively, of a rough buck and to insure a firm and rigid contact for the plaster terminal. The cars and the base may be provided with apertures 15 to receive nails or other securing means.

In installation, the device is set up around the corner of the rough buck and securely nailed in place. The finishing members, such as the door jamb and stop, may then be applied. Plaster C may then be applied over the lath or screen (not shown) the thickness of the plaster being defined by the portion 11.

In Fig". 2 I have shown a slightly modified form of my invention, the only diilerence in the two being that the cars 16, 17 are longer and are cut through to the edge of the base. By this modified device, a more certain and more rigid Contact is had with the rough buck and. the possibility of injury from a blow directly on the face of the portion 11 (Fig. 1) is much reduced Of the two forms here illustrated. the form indicated in Fig. 2 is con sidered the more preferable, being stronger and more easily handled, the cars 13 shown in Fin. 1 being of such small size as to be capable of easy destruction by contact in shipping and handling.

The provision of the cut-away portions 16, 17, enables the insertion of wedges between the buck and the jamb without interference with the metal portion of the terminal. By placing the wedges at points between the portions 17, they may be positioned in the same manner as though the plaster terminal had no part projecting into that space.

Thus it will be seen that my invention provides a plaster terminal that is simply made, easily handled, easily installed by unskilled workmen, and highly ehlcient. The strips can be furnished in any desired length or cut to any convenient size without destroying the efliciency thereof.

Obviously modifications and variations may be made in the design and construction here illustrated, and I do not wish to be limllll) ited except as indicated in the appended claim.

I claim:

A device of the class described consisting of a strip of metal having a rebent outer margin constituting a plaster anchor or bead, the inner edge being slitted at intervals, alternate sections of the slitted edge being bent at right angles, the series of angularly disposed sections being adapted to lie alongside of and be secured to a wood frame member, the portion of the strip between the bent sections and the bead constituting a plaster defining terminal.

In testimony whereof I have affixed. my signature.
