UNITED STATES PATENT QFFIGE.

E. S. TORREY AND J. TORREY, 0F NEW YORK, N. Y., ASSIGNEES WASH- INGTON L. GILROY.

IMPROVED WEATHER-STRIP.

Specification forming part of Letters Patent No. 74,077, dated February 4, 1868; reissue No. 3,174, dated October 27, 1868.

To all whom it may concern:

Be it known that WASHINGTON L. GIL` ROY, of Philadelphia, in the State of Pennsylvania, did invent a new and useful Improvement in the Construction of Weather-Strips, composed of wooden n1oldings,.or their-equivalent, and India rubber, or its equivalent, for windows, doors, Ste.; and we, E. S. TORREY and J TORREY, of the city, county, and State of New York, assignees in full of the said WASHINGTON L. GILROY, do hereby declare and ascertain the said improvements as follows:

Figure l representing a front view of the weather-strip, Fig. 2, a transverse sectional view in the accompanying drawing:

In weather-strips made before the present improvements, the elastic material has been inserted in one of two ways, namely, perpendicular to the face of the wooden molding, or in a loop or tube form. These are Well known, and we need not, therefore, more particularly describe them. These modes of construction having serious objections to urge against them in practical use, the rst improvement is to obviate them, which it most effectually does; and the second improvement is in the mode ot' fastening the elastic medium into its wooden .matrix by means of cement, instead of tackin g, as has always before been done, and which is peculiarly objectionable in the slender, light strips most desirable for this purpose. In-

stead of inserting the flat, straight, elastic that the portion that projects beyond the surface of the strip acts as an elastic readily-yielding spring, that will it surfaces thatk are quite unequal, and the strips themselves need not be so accurately cut or inserted to be more eective than those that do not incline.

There is an inclined saw-kerl, or narrow deep groove, cut into the wooden strip A, at w, and the India rubber, B, is put therein, and secured with a suitable cement. It will be -noticed that the light slim molding would be weakened by this groove w, and that, it' the rubber were pinned or nailed into it, the molding would be still more weakened. Therefore, cement is used for the double-purpose of more e'ectuallyuniting the rubber B andmolding A, but also for strengthening and solidifyin g the molding.

Having thus fully described the improved construction of Weather-strips, composed of f rigid strips of wood and elastic medium,
