PlVOTAl. SUPPORT FOR SASHES.
SPECIFICATION forming part of Letters Patent No. 351,936, dated November 2, 1886.
Application filed January 21, 1886. Serial No. 189,318. No model.) I
To all whom it may concern.-
Be it known that I, LoUIs PFINGST, a citizen of the United States, residing at the village of Pullman, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Pivotal Bearings for Sashes, for which I desire to secure Letters Patent of the United States, and of which the following is a specification.
The object of my invention is to provide such apivotal mounting for sashes used in the roofs of street and railway cars as ventilators,
in transoms, and similar places as shall perunit free pivotal movement of the sash, and also operate to hold the sash with sufficient firmness and stability in any position in which it may be placed, and which shall also-be cheap of construction, simple, and not likely to get out of order. .To this end I propose to provide the sash at each end with pivotal extensions or shafts, and to place between each of the said pivotal extensions and the socket provided therefor in the framework of the casing, about the opening filled by the sash, springs, attached, preferably, to the pivotal extension andcbearing upon the socket, or, if
preferred, attached to the socket and bearing upon the pivotal extension, so as to furnish a certain amount of resistance to the turning of the sashthat is, not enough to prevent its being readily changed from one position to another, but enough to hold it in any position in. which it is placed against displacement from the jarring of the car, or from similar causes.
In the drawings forming part of this specification, Figure 1 shows a sash in position having one of my pivotal bearings at each end. Fig. 2 is a cross-section of one of the pivotal bearings, showing it in position in its socket. and Fig. another modification, in which the spring is attachedto the socket instead of to the pivotal extension. Fig. 5 is a cross-section taken on the line 5 5, Fig. 1.
The essential feature of my invention con sistsin the spring E, lying .between the pivotal extension B from the sash and the socket A. This spring may assume a variety of forms, all of which are within my invention. Thus it may be a single spring passed through a central slot in the extension B and curving Fig. 3 is a modification of the same,
about it, as shown in Fig. 2, or it may be a double spring attached by a bolt or rivet'to the extension B, as shown in Fig. 3, or it may" be attached to t-heinterior of the socket, clasping the extension, as in Fig. 4; and many other obvious modifications might readily be suggested. The pivotal extension B may be attached in any desired manner to the sash. I prefer using a plate, 0, screwed to the face'of the sash and bent at right angles across its edge, the pivotal extension projecting from the latter part of the plate. This construction permits the point of attachment of the plate 6 to the sash to be on the outer surface of the sash, and therefore considerably more convenient of access. It also gives a firmer setting for the pivot than where the plate to which the latter is attached is secured merely to the edge of the sash.
I am aware that it has been heretofore proposed to use pivotal bearings for sash in connection with springs of various forms. My
invention consists in the application of a spring 7 5 of circular form attached either to the pivot or to its socket, and bearing against the inner concave surface of the socket,. or clasping the pivot, according to its location. This construction gives the largest possible frictional surface, giving a higher degree of stability to the sash in any position in which it may be placed than has been attained by the construc- 3. As a sash-bearing, the combination of plate U, bent at right angles and having projecting from it the pivotal extension B, in coinbination with a socket and a spring, substantially as described and shown.
