Description
Aug. 21, 1934. E. D. DAVIS SPRING vmmusuwmrzw MEANS Filed July 28, 1933 Patented Aug. 21, 1934 UNITED STATES PATENT OFFICE SPRING ADJUSTMENT MEANS tion of Illinois Application July 28, 1933, Serial No. 682,715
2 Claims.
This invention relates to spring adjustment means and more particularly to means for increasing the tension of a spring connecting two separable related members, such as a door and door frame.
An object of the invention is to provide simple and efiective means for changing the tension of a spring between two related parts. A further object is to provide adjustment means for releasably anchoring one end of a tension spring, and for increasing or decreasing the tension thereof. A further object is to provide improved means for anchoring or locking a spring to an attachment plate. Other specific objects and advantages will appear as the specification proceeds.
The invention is illustrated, in a preferred embodiment, by the accompanying drawing, in which- Fig. 1 is a plan view of an attachment plate embodying one phase of my invention; Fig. 2, a longitudinal sectional view, the section being taken as indicated at line 2 of Fig. 1; Fig. 3, a broken sectional view, similar to Fig. 2, but showing a spring attached to the plate; Fig. 4, a view similar to Fig. 3, but showing a modified form of spring attached to the plate; Fig. 5, a broken perspective view of the type of spring shown in Fig. 4; and Fig. 6, a broken plan view of a modified form of anchoring lug.
In the illustration given in Figs. 1 to 3, inclusive, 10 designates an attachment plate having its central portion raised at 11, and having U-shaped slots 12 formed in the raised portion to provide attachment lugs 13. The ends of the plates are preferably provided with screw openings by means of which the plate may be secured to a door, door frame, or other support. The lugs 13 are adapted to receive the ring end 14 of a tension spring 15, as shown more clearly in Fig. 3.
The series of attachment lugs permit the ring 14. of spring 15 to be shifted longitudinally to increase or decrease the tension of the spring; at the same time, the pull of the spring is exerted substantially longitudinally of plate 10, thus decreasing the strain on the attachment screws, nails, etc.
In the modification shown in Fig. 4, the spring 16 is provided with an offset ring 17 which enables the ring to be attached to one of the lugs 13 without bending or distorting the end of the spring. The construction of the offset ring 17 is shown more clearly in Fig. 5.
In the modification illustrated in Fig. 6, the plate 10' is provided with an attachment lug 13' having at its top a laterally extending locking boss 18. With this construction, any tendency for the end ring of the tension spring to slip off the attachment lug is overcome.
It will be noted that in each of the modifications illustrated, the attachment lug 13 lies in the plane of the plate 10, or in the plane of its raised portion 11, so that there is no projecting hook or catch. Each of the lugs 13 is guarded by the raised surface of the plate, while at the same time, the U-shaped slots permit ready attachment of the spring thereto.
The adjustment plate is applicable for use on a door or door frame in conjunction with a tension spring. It is particularly useful in combination with a door check of the type described by Gustav A. Carlson in co-pending application Serial No. 631,718. The adjustment plate permits shifting of the spring to obtain the precise tension needed for accurate and efficient operation of the door check. It is obvious that the invention is also useful in connection with other separable related parts.
While I have described a specific form of attachment and adjustment means for the tension spring, it is obvious that the principle of my invention may be embodied in a variety of other forms. The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.
I claim:
1. An adjustment plate for use with a tension spring equipped with an end ring, comprising a plate having a central raised portion, a series of U-shaped slots formed therein and providing a guarded series of attachment lugs, each of which is adapted to receive the end ring of said spring.
2. An adjustment plate for use with a tension spring equipped with an end ring, comprising a plate having a raised central portion, a series of slots formed therein and attachment lugs within said slots, said lugs having an offset locking boss at their inner free ends.
EDWARD D. DAVIS.
