WARRENJXLLEN, OF OSWEGO, NEW YORK.
IMPROVEMENT IN DOOR-SPRINGS.
Specification forming part of Letters Patent No. 105,025, dated July 5, 1870.
Figure 1 is a perspective view of my im-' proved door-spring as attached to a door. Fig. 2 is a top or plan view of the same;
' This invention relates to certain parts hereinafterto be described, and is designed as an improvement upon the patent of Charles A. Peck, dated December 29,1857, otwhich patcut I am now sole owner; and it consists in the use of a rubber roller attached to one arm of a double-armed lever in such a manner as to operate directly upon the surface of the door, as will-hereinafter be described.
A in the drawings may represent the frame 4 of the door B, ,the door; 0., the case or box containing the coiled spring; G, the lever, formed with arrns'on its opposite sides at angles to each other; H, roller provided with rubber.
Ais the frame-work of a door,to which is secured the case or box 0, containing a coiled spring. This case or box 0 is provided or otherwise. formed with a metallic plate, a, through which the case or box is connected to the said frame-work by screws or bolts.
K is a coiled spring, inclosed within the case or box, attached at one end to a plate on the inner circumference, or to the case or box itself, the other end passing through a slot or otherwise ad ustably secured to the arm]; of the angled lever G, so as to increase the tension of the spring as it loses its elasticity from long usage.
G is the lever, formed with arms f b, arranged at angles on its opposite sides, the arm f designed as an axis for thecoiled spring K,
inclosed within the case or box C, while the arm I) is intended to close the door, being provided with a roller covered with elastic or other suitable material to prevent in its path the marring of the door.
M is the cap or: the box or case, retained firmly in its proper position by means of a nut or pin passing through the angled arm f of the lever G. The construction of the lever G, provided with its roller in the form shown and described, allows all slots, plates, and levers on the door 'to be dispensed with.
It will be thus seen that I have constructed a neat,'s'ubs tantial, and effective device for closing doors, cheap in its construction, and
, readily applied to the frame-work or casing of any door by the mere use of two or three screws. By the employment of the lever formed in one piece with the arms 1' and b, the former serving" as an axis for the support of the spring, while the other carries a rubber roller in such a manner that the rubber roller in its path,
acting directly on the door, does not deface or injure its surface, and at the sametimedispensing with all guides, rails, or plates on the door. I
Itwill also be distinctly understood. that l do not claim to have invented a coiled spring inclosed within a box or case for closing doors, as such has heretofore been accomplished, and is shown in the patent of Chas. A. Peck, of
which I am sole owner by assignment.
I am aware that the general arrangementof the parts in themselves is not new. Such I do not claim but,
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-" The single double-armed lever formed in'one piece, one'arm of which serves as an axis for the coiled spring arranged within a case, the
otherforming a journal for the wheel provided with a rubber band, which operates directly upon the surface of the door, all arranged and operating as herein described.
- To the above I have signed my name this 31st day of March, 1870.
WARREN ALLEN.
