TREAD FOR STAIRS.

SPECIFICATION forming part of Letters Patent No. 621,398, dated March 21, 1899. Application iiled March 14, 1898. Serial No. 6731708. (No model.)

ro the slipping of the feet, and has for its object to provide a new and improved tread for this purpose.

My invention is illustrated in the accompanying drawings, wherein- Figure l' is a plan view showing the parts of the tread before being placed in the bath. Fig. 2 is a section on line 2 2, Fig. l, after the tread has been immersed in the bath. Fig. 3 is a view showing the tread in position on a zo stairway. Fig. 4 shows the tread applied to a manhole-cover. Fig. 5 is a section on line 5 5, Fig. 4. Fig. 6 shows the tread in the bath.

Like letters refer to like parts throughout the several figures.

The object of my present invention is to provide an article of manufacture which may be attached to the steps of stairways orto other places with which the feet come in contact and which When so attached Will prevent the 3o slipping of the feet.

In carrying out my invention I provide a series of strips of material A, this material be'- ing of such a nature as to adhere, as it were, to the feet and prevent slipping. Any desired 3 5 material for this purpose may be used-such,

for example, as lead. These strips may be of any desired length, and are preferably provided with inclined edges. Between the strips A, I provide a series of strips B of more rigid 4o material-such, for example, as copper-a portion of the surface of the strips B being exposed between the strips A. It is of course evident that any desired material may be used for this purpose. The strips A and B are then attached to some suitable support C of material which is not a conductor of, electricity such, for example, as wood-or which has been treated so as to destroy its conducting properties. These strips may be attached in their 5o proper relative position to the support C in any suitable manner-as, for example, by means of nails or the like C'. The series of strips on this support are then placed in anY any suitable electrolytic bath may be used, i

and I of course do not limit myself in this Vhen the deposited metal D is particular. of sucient thickness, the tread is taken from the bath and removed from the support O. The tread is then ready for use and is attached to the stairway or other place With the deposited metall) down, Vso that the non-slipping material A is exposed on the surface, as illustrated in Fig. 3. The non-slipping majterial thus prevents the slipping of the feet, and the deposited metal D iirmly binds the several strips together. The strips B, which are of more durable material than the strips A, hold the parts together and prevent the strips A from getting out of shape and also from becoming easily worn. It Will thus be seen that I have here a simple and durable tread which may be applied to any surface with which the feet come in contact Where it is desirable to prevent the feet from slipping. In Figs. 4 and 5 I have shown the tread as applied to a manhole-cover. In such constructions the tread would be made in the same manner as for stairs, the deposited metalD forming an outer casing in which the strips A and B are held. It is of course evident that any desired number of pieces may be assembled together in l. As an article of manufacture, a tread adapted to be attached to stairs or other places with which the feet come in contact and comprising a series of strips of non-slipping material, a series of strips of harder material in- IOO termediate or between the strips of non-slipping material, the several strips placed in proximity to each other so as to form a praetically continuous surface, and a layer of deposited metal which engages the several strips and binds them firmly together.

2. As an article of manufacture, a tread for preventing slipping of the feet, comprising a series of strips of non-slipping material provided with inclined or beveled edges, a series of strips of harder material also provided with beveled edges and placed intermediate or between the strips of non-slipping material,the several strips associated together so as to form a substantially continuous surface, and a coating of electrically-deposited metal on one of the continuous surfaces formed by said strips, said electrically-deposited metal engaging the strips and binding them firmly together.

3. As an article of manufacture, a tread to prevent slipping of the feet, comprising a series of strips of non-slipping material, a

series of independent strips of harder material intermediate or between the strips of nonslipping material,the several strips associated together so as to form a substantiallyeontinuous surface, and a binding device adapted to firmly bind the several strips together.

4. As an article of manufacture, a tread to prevent slipping of the feet, comprising a VILLIAM II. VINSLOVV.
