My invention relates to a spring attaching means.
The object of my invention is to provide an attaching means for coil springs; such as a commonly used for opening and closing screen doors or the like.
A further object of my invention is to pro vide an attaching means by which the spring may be adjusted to any desired tension.
10 A still further object of my invention is to provide an attaching spring that will operate either right or left hand doors.
A still further object of my invention is to provide attachments for a spring removably arranged without the use of tools.
A still further object of my invention, is to provide attachments for a coil spring that is inexpensive, simple to apply and eficient in action by reason of the spring adjusting means to vary the tension of the spring.
These and other objects will be hereinafter more fully explained, reference being had to the accompanying drawings forming a part of this specification and in which similar characters will apply to similar parts in the different views.
Referring to the drawings Fig. 1 is an elevation of a coil spring and the attaching means assembled.

showing the spring applied to the left side thereof.
Fig. 14% is a similar view showing the spring applied to the right side of the door, it being understood that the spring is always applied to the hinged side of the door.
My invention herein disclosed consists of a coil spring 1, having a lug 2, firmly secured on the upper end thereof; the extended por tion being polygonal as at 2, to receive a winding bar hereinafter described.
The opposite or lower end of the spring has an extended portion 3, to prevent rotation as the spring is wound, the said portion being seated on a plate 4, the said plate having an arcuate portion 5, axially aligned and adapted to seat in the lower end of the spring by which means the said spring is firmly supported in operative position when opening or closing the door.
It will be understood that Figure 1 illus trates the approximate position of the spring as applied to the left side of a door, while Figure 13 illustrates the plate l as attached to the door casing by means of screws or like fastening means passing through the apertures A, while the upper end of the spring is suitably anchored to the door through the medium of a relatively long and narrow plate 6, likewise held in proper angular position by screws. The plate 6 has one end upturned as at B, and such upturned end is provided with an aperture C. The opposite end of the plate 6 is upturned at D for forming a stop lug to limit the longitudinal movement of a winding bar 7, and a pair of lugs E are upturned from the sides of the plate 6 for limiting the lateral movement of said bar.
The bar 7 adjacent one end is widened as at 8, and such widened portion is provided with a polygonal opening 9 adapted to engage over the polygonal end of the lug 2. The end of the bar adjacent the portion 8 is provided with a rounded, slightly upturned lug 10 adapted for normal engagement within the aperture C, while the opposite end of the bar is curved upwardly and outwardly for forming a hook-like finger engaging portion 11. The base of the hook ed claims.
l1 normally rests behind the end D. Thus the bar normally entirely lies upon the plate 6 and is positively held against longitudinal and lateral movement, assuming there is any tension whatever on the spring. The plates 4 and 6 are angularly disposed with respect to the door, and in alignment with each other, and so spaced that it becomes necessary to slightly compress the spring 1 in positioning the bar 7 in operative position. This will avoid the possibility of the spring becoming disengaged from either the bar 7 or the arcuate portion 5 when the door is opened to the limit of its movement.
When it is desired to place additional tension upon the spring 1, the operator lifts the end of the bar 7 by means of the hook 11 and slides the bar to the right until the end lug 10 becomes disengaged from the aperture C. The upper endoi the spring is then flexed outwardly and held in such position while the operator removed the bar 7 from the lug 2. The bar is then moved in a direction away from the operator and again engaged with the lug 2, at which time. the bar is pulled toward the operator sufliciently far to permit it to again align with the plate 6, at which time the lug i0 is inserted into the aperture C. Upon release of the hook 11, the tension of the spring will snap the bar into firm engagement with the plate 6 with the base of the hook positioned behind the end D. The tension of the spring is in a clock-wise direction, hence, when the operator pulls the bar 7 toward him, the lug 2 and spring 1 isturned in a counter-clock- Wise direction, thus increasing such tension. The greater the tension, the more firmly the bar will engage the plate 6;
It is to be understood that the invention is not limited to the precise construction shown, butth'at it includes within its pur- Vie-W Whatever changes fairly come within either the terms or the spirit of the appenda mwp V 1 A spring tension device for a coil spring comprising anattaching plate for one end of the spring, said plate provided with an offset semi-cylindrical extension for receiving the coils of the spring thereover, said spring having the free end of its oonvolutions,terminat-' ing in alateral extension, a bearing surface for said last named extension carried by the plate,-.a'winding nut for the spring rigidly supported by the opposite end of the spring, a. winding bar adapted to engage said nut, keeper for said bar co-exitensive in length with the bar, and means carried by said keeper for holding the bar against longis tudinal and lateral movement when in use.
2. A spring tension device for coil springs comprising a fixed support for one end of the spring, said support having an offset semicyl-indrical extension adapted to engage within the coils of the springs, the free end of the spring terminating in a tangential extension, said support providing a bearing surface for the last named extension, a winding nut rigidly positioned upon the opposite end of the spring, a Winding bar and a keeper therefor, said winding bar provided with an upturnedend extension and a hook-like finger engaging portion, said bar having an opening formed therein corresponding to and adapted to engage said nut, said keeper and said bar co-extensive in length, an upturned apertured end portion adapted to be engaged by the upturned end of the bar and upturned side lugs on said keeper, substantially as shown and described.
In testimony whereof I affix my signature.
