WILLIAM H. MAINE, OF ABINGTON, MASSACHUSETTS.
IMPRovEMl-:NT IN CURTAIN-FIXTURES.
Specification forming part of Letters Patent No. 170,006, dated November 16, 1875; application tiled October 16, 1875.
T o all whom it may concern:
Be it known that I, WILLIAM H. MAINE, of Abington, Plymouth county, Massachusetts,
` have invented a new and Improved Curtain- Roller, of which the following is a specilication:
Figurel represents a vertical central section of my improved curtain roller, and Fig. 2 a detail end view ofthe locking-cam sleeve as detached from the roller. f
Similar' letters oi' reference indicate correspondin g parts.
The present invention relates to that class of spring curtain-rollers which are provided with a device for preventing the unwinding of the spring when the roller is removed from the brackets. I I
rlhe invention consists ot' a spring-roller with stationary cam-sleeve socketed to the end in connection with a loose pin sliding in a hole of the spindle or shaft, for engaging the cam-sleeve at the instant when the spindle is taken out of the bracket.
In the drawing, A represents a spring curtain-roller, ofthe usual construction, which is provided at the end with a metallic camsleeve, B, set securely by an outer collar or rim, and raised ribs a into the cap or end piece of the roller. The earn-sleeve B lits loosely, by an interior collar, on the shaft or spindle C ot' the roller, the shaft being rigidly held in position in the customary manner, `by its flattened end, when seated in the supporting-bracket. rlhe cam-sleeve B is formed at the interior with one or more recesses and teeth, d, against which a conically-tapering pin, I), that slides in a corresponding hole of the spindle at a point within the cam-sleeve, is thrown by centrifugal force, imparted by the sudden rotation of the spindle when being taken out of the bracket. The pin D is loosely itted into the'hole of the spindle, and retained therein when the roller is placed in position on the brackets, by being seated vertically in the hole, with the larger end at the top, so that the roller and cam-sleeve can clear the pin and revolve without obstruction. The pin is so arranged in the spindle that it assumes a vertical position when the roller is placed in the brackets.
Assoon as the roller is taken out of the bracket, the spiral roller-spring. actson the spindle, revolves the same, and throws the pin instantly out ot' its seat against a cam of the sleeve, so as to retain the spindle and prevent the unwinding of the spring. The roller thus remains in locked position as long as it is out of the brackets, and is instantly available for use when replaced in the brackets.
Having thus described my invention, I claim as new and desire to secure by Letters Patent A 1. As an improvement in spring curtainrollers, the improved spindle-locking device, consisting of a curtain-roller with fixed camsleeve at the end, in combination with a sliding pin seated in a perforation of the spindle within the sleeve, to arrest the spindle when the roller is detached Vfrom the supportingbracket, substantially as specified.
2. The spindle ofa spring curtain-roller, provided with a guide-hole for the sliding locking-pin at a point within the cain-sleeveof the roller, the pin-hole being in vertical position when the spindle is seated in the brackets, substantially as specified.
WILLIAM H. MAINE.
