Letters Patent No. 82,920, dated October 13, 1868.
IMPROVEMENT IN BLIND-HINGE.
The Schedule referred to in these Letters Patent and making part of the same.
Hin-
To all whom it may concern:
Be it knownthat I, CHARLES B. CLARK, of the city of Buffalo, county of Erie, and State of New York, have invented a certain new and useful Improvement in Self-Locking Blind or Shutter-Hinges; and I do hereby declare that the following is a full andv exact description thereof, reference being had to the ,accompanying drawings, making part of this specification, in Which- Figure l isfan elevation, showing the application of my improved hinge to a shutter.
Figure 2, a horizontal section thereof, in plane of line x x.
Figure 3, a view in perspective of the two leaves of the hinge, detached.
Figure 4, a diagramv showing the pintleJ and socket reversed in position from fig. 2.
Like letters of reference indicateV corresponding parts in all lthe ii-gures.
My improvement belongs to that class where the joint ofthe lower hinge has a degree of looseness or play, to allow the parts to lock and unlock by simply throwing the bottom of the shutter out or in.
The object is to so form the pint-le and socket that when the shutter is opened, a positive lock will be produced, but in allother positions, either turning or closed, the pintle will form a close joint with the eye, thereby preventing rattling. In th accompanying rhawings, A indicates the blind or shutter, B the casing, C the uppenand D the lower hinge-plates. The pintle, a, of the lower hinge, is made cylindrical, but has formed in its surface, on one side, a longitudinal angular recess or slot, b, as' clearly shown.'
The socket or eye c, to receive the pintle, is circular, or nearly so, except that on one side, outside its periphery, it is rso notched or recessed as to form a' projecting` catch, ll.
lVhen lthe shutter is wide open, the catch fl and recess b engage, and a free space f is left in the eye for disengagement again, as clearly shown in iig. 2. In all other positions, however, either turning or closed, the pintle simply rests in the circular part of the eye or socket, and iills the same without any irregular motion or play. When the blind is wide open, the bottom falls back by its own gravity, and yself-locks.
. It is opened bya single push.
I am awa-1e that many blind-hinges are in use in which thebottom of the blind is thrown in and out to engage and disengage the connection. In some of these the blind is held by running down an inclined plane in others, a positive lock is insured; but in such cases,I so far as-I know, the eye or socket, in which,
the pintle rests, is made elongated, and in such foiin that the joint between the pintle and eye is loose, and in turning open or', closed, an irregular shaking or rattling eliect is produced.
Itis my object to obviate these diflicultiesby sov constructing the parts that, -when opened, a positive lock is produced, but when in any other position, turning or closed, the pintle will rest closely in the eye without any loose play. This I do by making the piutle cylindrical, with the depressed slot b and the eye circular, with the projecting catch d, as before described. This accomplishes perfectly the purpose designed, keeping the` parts tight, except .at the moment of locking. v
This hinge is simple and cheap in construction, since the whole can be cast, with the pintle and eye complete, without fitting or dressing, and the whole connection is formed with the lock inside, and without the addition of a loose pin or any other parts. The A complete hinge is formed by the union of the two ordinary leaves or plates. v
In addition to the above, this simple construction gives the lower hinge the same exterior form as the upper, thus conducing to general harmony of appearance. tion necessitates a deviation lfrom the usual form, which disigures the blind.
By my method of recessing the pintle, and its conl sequent self-engagement with the projection in the eye-piece, I believe my invention t` be thereby the simplest and best of the class of self-locking hinges.
I do not claim broadly a loose-jointed, self-locking hinge, as I am aware that the same is not new; but What I claim as my invention, and desire to secure by Letters Patent, is-
Forming the cylindrical pintle a with the depressed slot b and the circular eye c, with outside catch d, thev whole combined and arranged as described, and oper-r ating in the manner and for the purpose specified.
In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
