LOUIS HELLNER, OFNEWV YORK, N. Y.

STALL-FLOOR.

SPECIFICATION forming part of Letters Patent No. 419,670, dated January 21, 1890.

Application filed April 4. 1889. Serial No. 305,922- (No model.)

1 To aZZ whom it may concern:

Be it known that I, LOUIS HELLNEB, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Stalls, of which the following is a specification.

This invention relates to an improvement in stalls by which the grating in the stallfloor is made cheap, durable, and easy of repair, as set forth in the following specification and claim and illustrated in the accompanying drawings, in which Figure 1 is a plan view of a grating in a stall-floor. Fig. 2 is a section along a: a", Fig. 1. Fig. 3 is a section along y y, Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, the letters A A indicate the sides of a stall. Into a suitable recess in the stall-flooris let the rectangular frame B, preferably of metal or durable material. The frame B communicates with a drain 0, so that moisture will drain off from the stallfloor through the drain 0. Said frame B has angular mortised seats to receive the bars D, which are angular in cross-section, so as to correspond to the mortised seats in the frame. The bars D are shown quadrangular in crosssection; but of course they might be made hexagonal or otherwise angular in cross-section, the mortised seats for said bars of course corresponding with the bars. By having the bars D angular in cross-section said bars will not turn in their seats, as might be the case if the bars were cylindrical. Byhaving the mortised seats for the bars formed angular, and by having the various faces of said bars formed to correspond to the angular mortised seats, when one face of a bar is worn or injured said bar can .be readjusted or reversed in the frame, so as to expose a fresh face of the bar to use. The bars can thus be made to last a long time, thus securing oheapness and durability.

To prevent the bars being accidentally removed from the frame, screws E are shown engaging the bars so as to clamp or look the bars in place. The screws are shown seated in recesses in the frame B, so that a key is required to loosen the screws. To reach the screws the frame B is simply lifted out of the stall-floor, so as to expose the side of the frame where the screws are situated. By making the metal work of non-corrosive material such as galvanized iron-cleanliness and durability of the metal work can be secured. By having each screw E engage a bar at one end the bar will not have to be drilled or perforated to receive the screw.

WVhatI claim as new, and desire to secure by Letters Patent, is

1. A stall having in its fioora rectangular frame provided in its uppermost edges with mortised seats, in combination with a series of independent angular bars separately and detachably held at their ends in the mortised seats and adapted to be removed, reversed, and replaced, substantially as described.

2. A stall having in its floor a rectangular frame provided with mortised seats, in combination with a series of disconnected independent angular bars detachably arranged at their ends in the mortised seats and each adapted to be removed, reversed, and replaced, and aseries of screws passing through the frame and respectively engaging the bars, substantially as described.

In testimony whereof I have hereunto set my hand in thepresence of two subscribing witnesses.

LOUIS HELLNER. Witnesses:

HENRY BURNETT, WILLIAM G. HAUFF.
