UNITED STATES PATENT OFFICE.
GEORGE C. GOURLAY, OF NEW YORK, N. Y., ASSIGNOR T0 HIMSELF AND ANDREW HUNTLEY, OF SAME PLACE.
PORT-LIGHT FOR VESSELS.
Specification of Letters Patent No. 30,519, dated October 23, 1860.
To all whom it may concern:
Be it known that I, GEORGE C. GOURLAY, of the city, county, and State of New York, have invented a new and useful Improvement in Port-Lights for Vessels of Navigation; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure l is a detached front or face view of my invention. Fig. 2 a view of the outer side of the same detached from the vessel. Fig. 3 a horizontal section of the same attached to a vessel. oo, Fig. l, indicate the plane of section.
Similar letters of reference indicate corresponding parts in the several figures.
The object of the invention is to obtain a port-light that may be applied to vessels, either iron or wooden ones, with facility and so as to form a perfectly water-tight oint.
To enable those skilled in the artto fully understand and construct my invention, I will proceed to describe it.
A, represents an annular rim or case which may be of brass or castiron and B, is an annular frame of the same material and which is connected to the rim or case A, by joints c, a.
The inner side of the rim or case A, has an annular groove or recess b, formed in it, which groove or recess causes an annular edge c, at the inner edge of the rim or case against which an annular rubber packing d, in the frame B, is pressed when-the frame B, is closed-see Fig. 3.
The frame B is provided with the usual glass C, and is secured irmly in a properly closed state against the rim or case A by buttons D, D, which are secured to the rim or case A and project over on the frame B when the latter is closedsee Fig. l.
The outer side of the rim or case A has an annular groove or recess c, in it. This groove or recess e, is about in line with the outer edge of the groove or recess b, as
shown clearly in Fig. 3. The rim or case A extends out from the groove b, suiiiciently to admit of screw holes f, being made through it.
The groove or recess e, is lled with a suitable cement e, white and red lead mixed in about equal proportion will answer a good purpose.
The outer side of the rim or case A is fitted or placed against the inner side of the vessel g, and secured thereto by screws It, the side of the vessel around the port hole being in contact with a fianch z', of the rim or case as shown clearly in Fig. 3.
In screwing up the screws L, the rim or case A is fitted or brought snugly up against the side of the vessel the recesses or grooves o, e, admitting of a requisite degree of yielding of the case transversely so as to form a perfect joint, the packing or cement e', performing its usual function, and being brought up snugly in contact with the sides of the vessel.
More than one annular cement groove c may be employed if deemed necessary. The grooves serve to retain the cement, preventlng it from separating or becoming misplaced. Where a packing such as rubber or other soft material is introduced, between the face of the frame A and the siding of the vessel, the frame A when screwed up is liable to spring or warp and injure the frame and become leaky.
I do not claim the employment or use of the rubber packing Cl, applied to the frame B, for that has been previously used; but
Having thus described my invention what I do claim as new and desire to secure by Letters Patent is- The construction of the face of the rim A with one or more annular grooves e, as herein shown and described.
GEORGE C. GOURLAY.
