TREAD FOR STAIRS, as.
SPECIFICATION forming part of Letters Patent No. 481,702, dated August 30, 1892.
Application filed June 11, 1892. Serial No. 436,339. (No model.) Patented in England April 7, 1891, No. 5,988; in France April 25, 189L110. 212,953, and in Belgium April 29, 1891, No. 94,712.
To all whom it may concern.-
Be it known that we, JONATHAN MASON and JOSEPH MASON, builders and contractors, of 15 Barbecan, in the city of London, and WIL- LIAM SQUIRES CODNER, iron-merchant, of 10 Queen Elizabeth Talk, Stoke Newington, in the county of Middlesex, England, have invented certain new and useful Improvements in Treads for Stairs and the Like, of which the following is a specification.
This invention relates to a novel manufacture of treads for stairs, coverings for floors, cover-plates for coal-holes, openings for hydrants, manholes for sewer ways, 850., steps for carriages and other vehicles, foot-plates for locomotives, deck-coverings for ships, and for other purposes, the object of the invention being to produce a durable non-slipping surface.
In the accompanying drawings, Figure 1 shows in plan View our invention as adapted to a stair-tread by way of example. Fig. 2 is a transverse section of the same, and Figs. 3 and 4 may be said to be diagrams showing two stages in the production of the treads according to our invention. Fig. 4. shows a modified form of rib, and Fig. 5 is a cross-section of the filling material.
A is the base-plate, of hardmetal-say mild steelwhich forms the wearing-surface, and c are strips of a softer material-say lead which are let into the base-plate and which form a non-slipping surface.
In carrying out our invention we form the plate with raised ribs and intermediate spaces undercut or of dovetail shape in cross-section, so as to provide a key or holding surface for the soft filling-pieces.
In the production of the plates we prefer to roll them; but we may also cast them, stamp them, or produce them in any other manner to receive the strips.
WVhen producing the plates A with the raised ribs and dovetail spaces by rolling when hot, we may proceed in the following manner-that is to say: We first obtain a plate with rectangular ribs a and spaces Z) and with a nosing c in the ordinary manner. WVe next subject the plate so formed to a second rolling operation with rolls of the forms (more or less) indicated by dotted lines at Fig. 4, by means of which each rib a is cut open, as it were, and one or more V-grooves d may be formed longitudinally thereof. At the same time the sides of the spaces will be pushed inward to give to the spaces 1) a double-dovetail shape, as seen at Fig. 4, or the rolls may be of inverted-V shape to produce a rib of the form shown at Fig. 4., in which figure the spaces will still be dovetailed. The plate so formed is ready to receive the strips of soft material. We next take strips of lead 6 of the section shown at Fig. 5 or a similar section, place them in the spaces 1), and subject them to pressure in a rolling-mill or otherwise, by which means the spacesb become filled up with the soft material flush with the highest point of the ribs a, as shown in Figs. l and 2, thus forming a non-slipping treading-surface having a frame, so to speak, formed by nonwearing hard-metal ribs 0..
The production of covering-plates of various kinds and other articles will be effected in practically the same manner, the plate being preferably inclosed in a metal frame.
The filling material may (in place of lead) be tarred rope, which will be compressed into the spaces while the plate is warm, or other soft non-slipping material may be employed. "What we claim is- A tread for stairs and other purposes, consisting of a plate A, of hard metal, provided with ribs a and undercut or dovetail-shaped spaces 1) between the ribs, in combination with filling-pieces e, of soft non-slipping material, placed in the spaces 1), as and for the purpose set forth.
