STAIR PLATE.

Application filed July 10,

This invention relates to stair plates and contemplates the provision of an individual frame for suitably enclosing and forfastoning a protective covering to the tread of a step. Our invention provides an economical and easily adjusted structure, readily securable to the horizontal surface of a step and presenting a good appearance, for maintaining asheet of suitable fioor surfacing or wearing material in operative position on the tread.

The various objects of our invention will be clear from the description which follows and from the drawings, in which,

Fig. 1 is a perspective View of a portion of a stairway showing our improved stair plate secured in place.

Fig. 2 is a vertical cross section of the same.

Fig. 3 is a bottom view of one end of our improved plate, and I Fig. 4 is a vertical section of a modified form of the nosing at the front of the plate.

In the illustrated embodiment of our in vention which shows one of the practical applications thereof, We prefer to provide a frame closedon three sides and designated generally by the numeral 10 for enclosing and protecting the edges of a sheet 12 of floor covering material. The frame is preferably made of sheet metal and has a large central opening 11 therein through which the sheet is exposed. The shorter edges of the frame which we will call the sides 13 and 1 1, and the longer rear edge which we will call the real-115 are made preferably as narrow as possible consistent with their function, which is to form a protective pocket 19 in which the corresponding edges of the sheet 12 are securely clamped, so as to present as good an appearance as is possible. Each of said sides and the rear may be made of pieces separate and distinct from each other if desired, and then suitably joined together near the corners of the frame, or the entire frame may be made of a single sheet of material as illustrated. In either case, said sides and rear each consists of an edge intended to cover and protect an edge of the sheet 12, an up er horizontal flange of little width bent rom the up er part of said edge, a lower flange refera ly slightly wider than the upper an'ge and bent from the lower part of said edge which is continuous and integral with, and joins said fiangestogether. The inner edges 1926. Serial No. 121,518.

20, 21 and 22 of the upper flanges 23, 24 and 25 respectively, arranged about the opening 1.1, are suitably bevelled so that the upper surface of the plate is substantially smooth and presents no objectionable projections on which a person using the stairway might trip. The front 16 of the frame 10 is not bent or folded over but preferably consists of a single sheet-like portion integral, con tinuous and flush with the upper flanges 23 and 25 whereby possibility of tripping on the smooth surface thus presented is eliminated.

At the termination of and integral with the front 16 is the nosing 17, which is suitably curved to fit the front edge of the stair tread and which is provided with suitable holes through which the screws 18 may be passed for securing the nosing in the front of the step. As shown in Fig. 4:, the front 16 may be corrugated for part or all of its length as at 20 to act as a scraper for removing mud and dirt from the shoes of persons using the stairway.

The lower flanges 26 of the sides 13 and 14 are bent about the edges of and securely clamped or forced on to the under surface of the sheet 12 which may be of linoleum, rubber matting, cork board, carpet or other suitable floor covering. The rear ends 27 of the flanges 26 are preferably suitably mitred at the juncture thereof with the ends of the underflange 28 of the rear 15, which may be similarly mitred as shown.

Said flange 28 is provided with perforations 29 each having an enlarged circular portion 30 and an elongated slotted portion 31. Thehead 32 of a nail is intended to be inserted through the enlarged opening 30 through which it may be readily passed into contact with the under surface of the sheet,

and thenthe entire nail moved forwardly so.

that the head 32 is arranged at the front end of the slot, the head pressed between the sheet 12 and the flange 28, and the shank 33 projecting through the end of said slot.

It will be noted that by arranging the fastening nails in the manner just described, it becomes unnecessary to drive nails through the frame or through the sheet 12. This results in several advantages including the'hiding of the unsightly nails from view, and the elimination of nail heads from the top of the plate. Such nail heads when driven into or arranged underneath the covering material are objectionable for the reason that they do not wear at the same rate as the covering material and. tend to raise ugly and dangerous lumps or projections in the plate. ith our improved arrangement, the nails are not only hidden but also prevent the formation of such lumps. However, to insure an underfaced smooth upper surface on the sheet 12 at all times, free from injury or distortion, we prefer to depress the material about the openings 29 slightly so that the top of the head 32 of the nail is flush with the under surface of said sh et. The flanges 26 terminate preferably at a point rearwa *dly of and in spaced relation to the nosing 17 in order to enable the nosing to fit the step throughout the entire length of said nosing. It will be understood that the length of the frame ma be made considerably less than the length of the step if desired, and that said frame may be made up in various predetermined sizes adapted to leave an uncovered margin about the sides and rear of the step.

To fasten our improved plate in place the nosing is arranged in contact with the front edge of the step and pressed there against while the rear edge 15 is somewhat raised. blow, while maintaining the pressure on the nosing, the rear 15 is lowered into position a hammer blow on the rear directly over each of the nail heads 82 driving the'nails into the step. The screws 18 are then driven into place, whereby the entire plate is secured in position with the fastening nails entirely hidden.

It will be seen that we have provided a structure for protecting the stair tread which is quickly fastened in place, which can be economically manufactured in a standard size to fit any step and which is durable and of good appearance. Nuther dirt nor dust can work their way between the various flanges of the frame and the sheet 10 and into the pockets 19 because of the tight fit of the bevelled edges 20, 21 and 22 against the sheet, whereby the plate may be readily maintained in a clean and sanitary condition. It will further be understood that various changes may be made in the structure shown and described, such as in the proportions of the parts, the use of separate pieces suitably joined together instead of a single piece for the frame, changes in the fastening means and other changes which are contemplated but not described in detail, without departing from the spirit and scope of this invention and the range of equivalents afforded by the appended claims.
