DOOR-CHECK.
SPECIFICATION forming part of Letters Patent No. 716,044, dated December 16, 1902.
Application filed March 21, 1902. $erial No. 99,284. (No model.)
.To all whom it may concern:
Be it known that 1, JOHN D. HUMPHREY, a
citizen of the United States of America, residing at New Britain, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Door-Checks, of which the following is a specification.
Figure 1 is an elevation View of a portion of a door and door-casing with a door-cheek attached which embodies said improvement. Fig. 2 is a plan view of the same. Fig. 3 is a view of the same device in sectional elevation on the plane 2 z of Fig. 4. Fig. 4 is a view in horizontal section on the plane y y of Fig. 3.
The object of the improvement is a production of a device denoted and adapted to be attached to a door and to its casing in such fashion as to retard the door in its closing movement and keep it from slamming. It embodies a spring which closes the door.
In the accompanying drawings the letter 0 denotes the door and b the door-casing.
The letter 0 denotes the frame carrying that part of the mechanism which is affixed to the door-casing. The letter (1 denotes a shaft hung in said frame. The letter e denotes a spring, by preference a coil-spring, attached to said shaft and elsewhere properly attached, so that it winds and unwinds with the rotary motion of said shaft. Said shaft carries an armf, which through link f and pintle f is in such cooperation and connection with the door that the opening of the door winds the spring, and then when the door is released the unwindingof the spring closes the door.
The letter g denotes a rotarily vibratory verge.
The letter h denotes a weight-rod, which is rotarily vibratory with the verge, and h denotes a weight which is adjustable along the weight-rod.
The letter is denotes a toothed wheel rotarily loose on the shaft (1. Its rotation causes the rotary vibration of the verge and the weighted rod. The toothed wheel is is connected with the shaft d through the medium of the pawl Z and the ratch-Wheel m, which is rotarily fast with the shaft (1.
The action and cooperation of the shaft d, spring 6, arm f, link f, pintle f and the door have already been described. When the door after being opened is released and under the action of the spring starts to close, 5 5 that closing action is retarded and regulated by the vibration of the verge and the weighted rod. The amount of that retardation is determined by the adjustment of the Weight 72. upon the weight-rod h.
I claim as my improvement 1. In combination, the toothed wheel, the rotarily vibratory verge adapted to be operated by said toothed wheel, the weight-rod rotarily vibratory with the verge, and the. weight adjustable on the weight-rod, all substantially as described. f p
2. In combination, the verge and weighted rod together rotarily vibratory, the toothed wheel adapted to vibrate said verge, the shaft on which said toothed wheel is loosely mounted, the pawl-and-ratch connection from said wheel to said shaft, the spring appurtenant to said shaft, and the arm adapted to be connected to and operated by the door, all substantially as described. JOHN 'D. HUMPHREY.
