PLASTER TERMINAL Filed Nov. 5, 1930 f (By 7 m Patented Aug. 29, 1933 UNITED STATES PLASTER TERMINAL Isaac A. Baum, Chicago, Ill.

Application November 5,

5 Claims.

My invention relates to building construction and particularly to a novel frame and plaster terminal arrangement.

A plaster terminal similar to that illustrated herein is shown and described in numerous prior patents issued to me, an example of which is Patent No. 1,744,732. In each of the plaster terminal constructions heretofore disclosed, the outer edge of the terminal flange is rebent toprovide a reentrant space that will act as an anchor for securing the plaster to the terminal flange.

This construction involves a practical objection, that is, the difficulty of flowing the plaster beneath the rebent marginal edge, and if the plastering is carelessly done, there will not be a firm anchor between the plaster and the terminal. This is essential, as plaster does not adhere to the surface of the metal.

I have provided a method of insuring a ilrm anchor of the plaster by the use of the expedient disclosed herein. The construction will be more readily understood by reference to the accompanying drawing, in which:

Fig. 1 is a perspective view of a portion of a plaster terminal and anchor strip;

Fig. 2 is a transverse sectional view through a frame to `which the construction shown in Fig. 1 has been applied, and

Fig. 3 is a perspective sectional view showing a slightly modified form in which the terminal flange is integral with the frame member.

In the drawing I have illustrated a frame member consisting of a web 10 constituting a jamb, and flanges 11 adapted to receive between them a wall of tile, masonry, or other construction.

Secured to the outer face of the flanges 11, are the plaster terminal members consisting of a continuous angle, one leg 12 of which is welded to the face of the flange 11 and the other leg 13 projects perpendicularly therefrom and terminates in a bare or unfinished edge 14. Projecting into the plaster space along side of the flange 13 is a flange 15 perforated as at 16 to admit the plaster therethrough. The flange 15 is preferably constructed in the form of an angle, the shorter leg 17 being welded to the inside face of the flange 13. Loops 18 matr be struck out of the channel flanges 11 to provide anchorage of the plaster to the frame.

In the construction shown in Fig. 3 the frame member is in the form of a buck having a web 19 and flanges 20, these flanges terminating in an integral, marginal flange 21 which likewise has a bare edge. To provide proper anchorage, the anchor flange 22 is secured to the inside face of 1930. Serial No. 493,591

(Cl. 'Z2-98) the flange 21. The operation is identical with that already described, the only difference being that the terminal flange is integral with the frame instead of being welded thereto.

In a construction such as described, the plasterer has no diillculty in applying the plaster at the terminal and a proper anchorage is insured.

Obviously the construction shown in Fig. 1 could be secured to Wood frame members equally as well as the metal frame, the base flange 12 being nailed to the wood in the usual manner. Other modifications will suggest themselves to those skilled in the art and I do not wish to be limited except as indicated in the appended claims.

I claim:

1. In means for defining a plaster limit, the combination with a frame element, of a metal flange projecting substantially perpendicularly therefrom, and a perforated flange projecting substantially perpendicularly from the inside face of said first named flange and into the plaster space alongside said metal flange, said perforated flange throughout its width being in spaced relation to the frame element.

2. In means for defining a plaster limit, the combination with a Vframe element, of a metal flange projecting perpendicularly therefrom andv a perforated flange secured to the inside face of said first named flange and projecting into the plaster space alongside said rst named flange.

3. In frame construction, the combination of a channel shaped frame, a plaster terminal secured to the outer face of a channel flange, said terminal including a continuous perpendicular flange having a bare edge, and a perforated member projecting into the plaster space adjacent to saidl plaster terminal.

4. In frame construction', the combination of a channel shaped frame, a plaster terminal secured to the outer face of a channel flange, said terminal including a continuous perpendicular flange having a bare edge, and a perforated member projecting into the plaster space adjacent to said plaster terminal, and vsecured to said plaster terminal.

5. In means for defining a plaster limit, the combination with a frame element,.o f a metal flange projecting substantially perpendicular therefrom and a perforated flange projecting from the inside face of said ilrst named flange and terminating in the plaster space in spaced relation to the frame element.
