GEORGE M. BOTI, OF ASHLAND, OHIO, ASSIGNOR OF ONE-HALF TO FRANCIS R. MARKS,
OF ASHLAND, OHIO.
Specification of Letters Patent.
Patented April s, 190e.
Application filed August 14,1905. Serial No. 274,095.
To cir/ZZ whom t may concern,.-
Be it known that I, GEORGE M. BoTT, a citizen of the United States, residing at Ashland, Ohio, have invented certain new and useful Improvements in Springs for Doors, Gates, and the Like, of which the following is a specification.
My invention relates to improvements in springs for automatically closing doors, gates, and the like.
The following may be stated as some of the objects of the invention, to Wit: to provide a simple and inexpensive device which may be readily applied to a door or gate, one which may be readily adjusted to vary the tension of the spring without the use of any wrench or other tool, one which will not get out of order, and which may be applied to finely-fmished doors without danger of damaging them.
Vith these and other objects in view the invention includes the various features of construction and arrangement and combination of parts hereinafter described, and particularly pointed out in the claims.
The invention is illustrated in the accompanying drawings, in which- Figure 1 is an elevation Fig. 2, a plan, and Fig. 3 a sectional detail, of a modification.
In the drawings I have shown, for example, the invention applied to a door, though it will of course be understood that it is equally as applicable to a gate or any swinging object which it is desirable to place under spring tension.
The numeral 4 on the drawings indicates the door post or frame, and 5 the door, only a portion of each being shown for convenience, as this is amply suicient for purposes of illustration. A base-plate 6, which may conveniently be made round, as shown, is designed to be secured to one of the aforesaid members, either the post or door, as may be desired, a convenient way of fastening being by screws 7, passing through holes in the plate. Lugs 8 project outwardly from the base-plate and to these are pivotally connected the rear corners 9 of a semicylindrical arm 9, which constitutes a spring-casing. Within the corners or ears 9b of the opposite end of the arm is j ournaled a roller 10 upon a pin or axle 11, the roller being preferably formed of or faced with some material which can roll upon a polished wood surface without injuring or marring the same. Within the semicylindrical arm is located a helical spring 12, one end of which is connected to a pin 13, connecting the edges of the arm, while the other end is connected to a lug or eye 14 on a block 15, sliding in guides 16 in the base-plate between the two arms. A thumb-screw 17, rotatably mounted in a lug 20 on the base-plate, but held against longitudinal movement therein, engages a nut 18 on the slide, and it will be readily seen that by turning the thumbscrew in one direction or the other the tension on the spring may be increased or diminished at will.
From the foregoing description it will be readily seen that if the base-plate be secured to the door-post with the roller bearing against the door the opening of the door will swing the arm against the tension of the spring, the roller rolling freely over the surface of the door and Without damage thereto. Of course the base-plate might obviously be applied to the door and the roller bear on the post, should this be desired.
Instead of using a threaded rod for effecting adjustment I may, if desired, provide a rigid lug 19, having a plurality of openings or recesses a, b, and c, designed to be engaged by the hooked end d of the spring, as shown in Fig. 3.
Having thus described my invention, whatl I claim is` y 1. In combination a base-plate, an arm pivotally connected thereto, a helical spring disposed longitudinally of the arm and having one end connected to the arm, and an adjustable connection between the other end of the spring and the base-plate, said connection comprising a plate slidably carried by the base-plate and having a lug to which the springis connected and a thumb-screw for moving said plate, substantially as described.
2. In combination abase-plate, a longitudinally-channeled arm pivotally connected thereto, a helical spring lying within the channel and having one end connected to the bracket and the other end to the arm and an antifriction-wheel journaled in the channel and projecting beyond the same.
In testimony whereof I aiX my signature in presence of two witnesses.
GEORGE M. BOTT.
