Definitions
- This recess should be of such depth that the end of the screw will remain in it when the screw is not binding upon the pintle, and in this manner the end of the screwl will serve as a stop to prevent the blind from being accidentally removed from its place while still permitting it to be swung freely. It will be understood that after the blind has been swung to the desired position, the two elements of the hinge may be locked by turning the finger lever and forcing the screw against the pintle.

`LOCK-HINGE.
SPECIFICATION formingjpart of Letters Patent o. 509,047, dated November 21, 1893. Application filed November 25, 1892. Serial No. 453,010. (No model.)
.To @ZZ whom it may concern.'
Be it known that I, GEORGE F. POTTLE, a citizen of the United States, residing at Medford, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Lock-Hinges, of
-which the following is a specitcat-ion.
the blind-that is, it works in front of the inner face ot' the blind-where it will be easily accessible to a person in the house in all its positions. At the point of bearing of the screw upon t-he pintle, I preferably cut away.thc same to form an annular recess therein, as shown at c. (See Fig. 3.) This recess should be of such depth that the end of the screw will remain in it when the screw is not binding upon the pintle, and in this manner the end of the screwl will serve as a stop to prevent the blind from being accidentally removed from its place while still permitting it to be swung freely. It will be understood that after the blind has been swung to the desired position, the two elements of the hinge may be locked by turning the finger lever and forcing the screw against the pintle.
In practice it is desirable to "prevent the 1. In a lock-hinge, the combination of a member carrying a pintle, a strap-member having a strap and an eye, the latter fitting over said pint-le, a screw tapped into the eye and adapted to set approximately parallel to the edge of the blind and a finger-lever securedv to the screw and yextending at an approximately right-angle to the same and adapted to work on the inner side ofthe blind, substantially as described.
2. The combination of a frame, ya pintlemember thereon carrying avertieal pintleannularly grooved, a blind, a strap-member B secured thereto and provided with' an eye, tting over the pintle, a horizontal threaded lug or boss formed on the eye, a screw Work- GEORGE E. POTTLE.
