Description
@uiten tatrs atmtt @ffice WILLIAM GILFILLAN, OF SYROUSE, NEW YORK, ASSIGNOR TO HIMSELB AND M. L. VAN HORN, OF NEW YORKOITY.
Lcters'ljatent No. 67,290, dated July 30, 1867.
IMPROVEMENT IN DOOR-SPRINGS.
TO ALL WHOM IT MAY CONOERN:
Be it known that I, WILLIAM GILFILLAN, of Syracuse, in the county of Onondaga, and State of New York, have invented a new and useful Improvement lin Door-Springs; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
The object of the present invention is to provide a spring attachment for doors, which, when the door is opened, will operate not only to close the same, but in such a manner as to exert the greatest power or force upon the door when closed, thereby holding it tightly closed, the importance and advantages of which are obvions. In the accompanying plate of drawings my improvement in door-springs is illustrated- Figure l being a front view of a. portion of a door and its frame, having my attachment applied to it, and
Figure 2 a plan or top view of tig. 1.
Similar letters of reference indicate likeparts.
A, in the drawings, represents a door, which uponone side, B, is hinged to or hung in the door-frame C. D, my improved spring attachment, which is constructed :1S follows. E, an arm secured in any proper manner to the outside of the door. This arm E projects horizontally from the door, and has ut or near its outer end F an upright spindle, G, made of a square shape in cross-section for a portion of its length. H, ahollow drum or cylinder closed at one end by a plate, I, having through its centre a round hole, J, of suitable size to fit over und to loosely turn upon the round portionof the spindle G. K, u. spring coiled within the box or drum H, with its outer end L secured in a slot, M, of the same, and its inner end folded about and around the squareshaped spindle G. To'the under side of the drum il is concentricztlly secured a small grooved pulley, N, from one point of which extends outward, a curved arm, P, with its outer edge grooved along or in thedirection of its length, the curve of which is eccentric to that of thc pulley N, but where it joins the same, is tangent, or nearly so, to its. periphery, as is plainly shown vin the drawings, tig. 2, more especially. R, a cord secured at one end Vto the outer end S of the eccentric arm P, along and in the groove of which it lies when the door is closed, in which case the eccentric arm P extends toward the door, (see fig. 2 of the drawings,) this cord :it its other end having a hook, T, fastened toit for hooking it-to, and in any of the series of apertures bin the flanged plato U secured to the upper rail V of the door-frame above the door. Wit-h u spring attachment ofthe construction and arrangement of parts above described, if its spring be first properly adjusted to the amount of force which is required to swing or move the door upon its hinges, by winding it up either more or less, as the case maybe, it is plain to be understood that by the opening of the door, (as the cord R at one end is fixed to the door-frame, while its other is hung to the door through the eccentric arm P, und other parts herein above explu.ined,) the said eccentric arm as the door opens will be swung around in an opposite direction to that in which the door is moving, thereby winding up the spring, which, reacting when the force that opened the door is removed, causes the door to immediately close or shut, where, through the action of the eccentric arm P and spring, it is held with great tightness, the spring attachment then acting with its greatest power.
I claim as new, and desire to secure lby Letters Patent- The hollow drum or casing H, with its eccentric arm P and coiled spring K, when connected with the doorframe through a. cord, R, o r its equivalent, and combined and connected together, substantially as and for the purpose described.
WILLIAM GILFILLAN.
