STALL-FLOO R.

SPECIFICATION forming part of Letters Patent No. 686,553, dated November 12, 1901. Application filed March 18,1901. Serial No. 51,641. (No model.)

T0 all whom, it may concer-77,:

Be it known that I, WILLIAM F. L. SPEN- GLER, a citizen of the United States, and a resident of Vailsburg, in the county of Essex and State of New Jersey, have invented a new and Improved Stall-Floor, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved stall-floor which is simple and durable in construction and arranged to insure perfect drainage and to permit of conveniently removing any one or all of the slats whenever necessary for cleaning the stall, for repairs, or for other purposes.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out'in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, formi-ng a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of the improvement as applied. Fig. 2 is a perspective view of one of the supporting cross-bars. Fig. 3 is a like view of one of the keys for holding the slats in place on the supportingbars. Fig. 4 is a cross-section of the improvement as applied. Fig. 5 is a longitudinal sectional elevation of the same. Fig. 6 is a transverse section of the same with parts shown in elevation. Fig. 7 is an enlarged longitudinal sectional elevation of the improvement on the line 7 7 in Fig. 6. Fig. 8 is a similar view of the same on the line 8 8 in Fig. 6; and Fig. 9 is an enlarged plan view of the improvement with one of the slats removed, but its key shown in position.

The stall-door consists, essentially, of a concrete foundation A, in which are embedded supporting cross-bars B B', spaced apart and located near the head and foot of the stall, as is plainly indicatedy in Figs. 1 and 5. The supporting-bars B B support spaced slats C, held in position by keys D, preferably made U-shaped and fastened by screws E tothe under side of the slats, so as to engage the dovetails B2, formed on the top of the supporting-bars, as is plainly illustrated in Fig. 2. The dovetails B2 rise from the top suring-bars B B', as indicated in Figs. 5, 7, 8,

`and 9.

Each of the supporting-bars is formed midway between adjacent dovetails B2 with longitudinally-extending grooves B3, registering with drainage-grooves A', extending longitudinally in the foundation A and leading at their lower ends into the branch channel A2 at the foot end of the stall. (See Fig. 5.) By the arrangement described the slats C are spaced apart and longitudinal drainagegrooves extend in the foundation A and the supporting-bars B between adjacent slats, and as the latter are raised above the level of the foundation it is evident that a perfect drainage is obtained, it being understood that the slats C are inclined upwardly from the foot end to the head of the stall, the same as the foundation A, previously referred to.

In order to place .the slats in position, it is necessary to first place a slat with its attached keys above the cross-bars B B and then slide the slat upward toward the foot end of the stall to engage the two keys of a slat with the corresponding do vetails B2 of the supportingbars B B'. When this has been done, the operator slips a locking-key F, of sheet metal or other suitable material, through registering grooves D' and B4 in the tops of the keys D and the dovetails B2, the head F of the key F resting against the upper end of the'said key and the lower end of the key F'being bent downward upon the lower side of the corresponding supporting-bar B or B to hold the keys D and the slats C from longitudinal movement unless the bent-down portions of the keys F are first bent back into a straight position.

In order to prevent the slats C from bend- IOO ing down or warping at their middle portions between the supportingbars B B', I prefer to attach bridges G to the under sides of the slats resting on the foundation A, as indicated in Fig. 5.

From the foregoing it is evident that the stall-floor isrvery simple and durable in construction, is not liable to, be injured by an animal, nor is an animal liable to be injured by it, and permits convenient removal of any one or of all of the slats for repairs or for cleaning purposes, as the case may be.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. Astall-tloor,comprisingsupporting-bars provided with dovetailed projections on their upper faces, and slats, each adapted to rest upon a dovetailed projection of each bar and provided on their under faces with keys, each key comprising two beveled members for engaging opposite sides of the dovetailed project-ions, on which the slat rests, as set forth.

2. A stall-Hoor, comprising a foundation, supporting-bars embedded crosswise therein and having dovetails extending above the foundation, slats resting on said dovetails, keys secured on the under sides of the slats and engaging said dovetails, and a locking device for locking the keys to the supportingbars, to hold the keys and slats against longitudinal movement, as set forth.

3. A stall-floor, comprising supporting-bars adapted to be embedded in the stallfloor foundation, the bars having raise/d dovetails at their upper surfaces, U-shaped keys for removably engaging said dovetails, and slats on which the keys are secured, as set forth.

4. Astall-loor, comprising supporting-bars adapted to be embedded in the stall-Hoor foundation, the bars having raised dovetails at their upper surfaces, U-shaped keys for removably engaging said dovetails, slats on which the keys are secured, and a locking device for locking a key to a supporting-bar, as set forth.

5. A stall-floor, comprising a foundation having longitudinal drainage-grooves, supporting-bars secured in the foundation, and each provided on its upper face with dovetailed projections and grooves between the said projections, said grooves registering with the grooves of the foundation, and slats adapted to rest upon the dovetailed projections and provided with U-shaped keys secured to their under faces for engaging the said projections, as set forth.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

WILLIAM F. L. SPENGLER.
