Description
UNITED STATES PATENT OFFICE.
JOHN BROUGHTON, OF CHICAGO, ILLINOIS.
Specification of Letters Patent No.
To all 'whom it may concern:
Be it known that I, JOHN BRoUGH'roN, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Vindow-Sash Fasteners; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the accompanying drawings, making a part of this speciication, in which- Figure l, is a front View of my improved fastener applied to a window. Fig. 2, is a horizontal section, and Fig. 3, a vertical transverse section of the same.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to an improvement in that description of fastener which employs a segmental bolt which has a raised rib of circular form on its upper side, said bolt being arranged to turn on a fulcrum pin, and in turning pass into a circular socket which has an eccentric surface for the rib of the bolt to bear against.
The nature of my improvement consists in introducing a spring between the rib of the bolt and the overhanging front plate of the socket in the manner and for the purpose presently described.
To enable others skilled in the art to make and use my invention I will proceed to describe it minutely.
A, in the annexed drawings represents the frame of a window; B, B, the sashes of the same.
C, is the segmental bolt, a, the circular rib on its upper surfaces, and e, the fulcrum of the bolt.
D, is the circular socket or cap. Its front plate or curtain 7L, only extends down even with the upper surface of the bolt in order that the bolt may pass under it when the rib a, enters the socket in the manner shown in Fig. 3.
E, .is a spring arranged on the inner surface of the curtain 71., in the manner shown, in order that the rib a, of the bolt shall have a yielding surface to play against in entering the socket, and the meeting rails of the two sashes consequently pinched or drawn close together, in a manner to form an air tight joint where they meet and prevent a SASH-FASTENER.
16,464, dated January 27, 1857.
rattling of the sashes with the wind. The spring or yielding surface, in connection with the rib also keeps the bolt, when in operation, securely in its place.
The advantages in the use of a spring, as herein shown and described over the use of an unyielding eccentric surface as in the old style of fastener, are these; the spring provides a yielding surface for the bolt to play against, consequently as the bolt enters the socket the sashes must be pinched together, and held in such a manner that rattling is impossible, and also the insinuation of wind between the joint. Again if the sashes by shrinking move apart there is no difficulty in forcing the bolt into the socket as the spring surface yields to the force of the bolt; and when the bolt is in the socket and the meeting rails of the sashes some distance apart it will be impossible for the sashes to rattle with the wind. And again if the sashes from the same cause should cause the bolt and socket to approach one another, instead of move apart, in a manner to destroy the advantage of having them bear against one another the spring, owing to .its form, would compensate for the same and bind the sashes together suiiiciently tight to prevent the insinuation of wind, and also rattling.
With the old style of fastener when the sashes shrink and cause the meeting rails to move apart it is very difficult often to get the bolt into the socket, owing to the socket and bolt being too far apart and also to the eccentric form of the rib of the bolt, or the curtain of the socket. And again when the meeting rails of the sashes, from a like cause, cause the bolt and socket to approach each other the advantage secured from the use of the eccentric rib or curtain is wholly destroyed.
What I claim as my invention and desire to secure by Letters Patent, is,
The employment of a spring E, on the inner surface of the curtain h, of the socket H, in the manner and for the purpose here in set forth.
