DOOR-SPRING 'WINDER AND SET.

Application filed January 5, 151 1.

To all whom it may concern ie it known that I, SAUEZ. PAuLsoN, a citizen of the United States, residing at Brooklyn, in the count of Kings and State of flew ork, have invented certain new and useful Improvements in DoorSpring lVinders and Sets, of which the following is a specification.

My invention relates to improvements in door spring winders and sets, the object of the invention being to provide an improved connection for one end of a coiled spring such as commonly used on doors which permits the ready adjustment of the spring to give to the latter the desired tension.

11 further object is to provide a device of this character which is of extremely simple construction, neat and attractive in appearance, and strong and durable in use.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and an rangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in longitudinal section illustrating my improvements. Fig. 2 is a top plan view. Fig. 3 is a view in side elevation. Fig. 4. is a view in section on the line 4tet of Fig. 3. Fig. 5 is an end view of the spindle, and Fig. 6 is a perspective view of the locking key. 7

1 represents a bearing bracket having per forated ears 2 for the reception of securing devices, and said bracket is provided with a longitudinal bore of two diameters, the upper smaller diameter constituting a cylindrical bearing 3, and the lower larger diameter constituting a cylindrical casing a in which a circular series of ratchet teeth 5 on a spindle 6 are adapted to turn.

The spindle 6 at its lower end is provided with a longitudinal recess 7 adapted to receive the inwardly bent end 8 of a coiled spring 9, the latter positioned around the spindle and compelled to turn when the spindle is turned to adjust the spring as is well understood in this art. It is, of course, to be understood that suitable means (not shown) will be provided for holding the lower end of the spring, but this invention has nothing to do with the particular support for the other end of the spring.

The spindle 6 is provided with an annularflange 10 which closes the lower end of the Specification of Letters Patent.

Serial No. 810,287.

casing t and bearsa'gainst the lower surface of the bracket 1. The extreme upper end of the spindle is made angular as shown at 11 for the reception of wrench to turn the same, and below said angular portion 11, the spindle is made cylindrical as shown at 12 constituting a journal to turn in the bearing 3.

The casing portion a of the bracket 1 is provided with an integral rectangular extension 13 on its outer portion which extension is provided with a slot 14, extending through the same and communicating with a longitudinal recess 15 in the interior of the casing. This recess 15 and slot 1 1- are designed to accommodate my improved locking key 16 which extends through the slot 14, and at its inner end is enlarged longitudinally of the spindle as shown at 1'? so that shoulders 18 are formed at opposite sides of the key which engage the walls of recess 15 and limit the outward movement of the key.

The extreme inner end of the key is beveled. or rounded as shown at 19. so that the turning of the spindle in one direction will cause the ratchet teeth 5 to engage this beveled surface 19 and force the key longitudinally and out of the way in recess 15.

After the spring is adjusted to the proper tension, the locking key 16 is moved inwardly so that it engages the ratchet teeth as shown clearly in 4, and securely holds the spring at the proper tension. In assembling the parts, the locking key is po sitioned in the casing, and then the spindle inserted, and after the parts are once assembled, the key cannot be lost.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination, a bearing bracket having a longitudinal bore of two diameters, and having a slot inthe wall of its larger diameter, a spindle having a journal fitting the smaller diameter and having a series of teeth adapted to turn in the larger diameter of the bearing, said spindle constructed at one end to facilitate its rotary movement,

and at its other end constructed for connection with a coiled spring, and locking key movable through the said slot in the larger diameter 01 the bearing bracket and adapted to lock with the teeth, substantially as described.

2. In con'ibiiiiation, a bearing bracket having a longitudimil. bore of two diameters, a spindle having a journal fitting the smaller diameter and having a series of teeth adapted to turn in the larger diameter of the bearing, said spindle constructed at one end to facilitate its rotary movement, and at its other end constructed for connection with a coiled spring, said bracket having a slotted extension, and a recess at the inner end of the slotted extension, a locking key projecting through the slotted extension and having an enlarged inner end movable in the recess, said key having a beveled inner end adapted to lock with said teeth, substantially as described.

In combination, a bearing bracket having a longitudinal bore of two diameters, a spindle having a ournal fitting the smaller diameter and having a series of teeth adapted to turn in the larger diameter of the bearing, said spindle constructed at one end to facilitate its rotary movement, and at its other end. constructed for connection with a coiled spring, said bracket having a slotted extension, and a locking key in said slotted extension adapted to engage the said teeth, said larger diameter of bore extending to one end of the bracket, and said spindle having an annular flange bearing against the lower end of the bracket and closing said larger diameter of bore, substantially as described.

4. In combination, a bearing bracket having a longitudinal bore of two diameters, a

spindle having a ournal fitting the smaller diameter and having a series of teeth adapted to turn in the larger diameter of the bearing, said spindle constructed at one end to facilitate its rotary movement, and at its other end constructed for connection with a coiled spring, said bracket having a slotted extension, and a recess at the inner end of the slotted extension, a locking key projecting through the slotted extension and having an enlarged inner end movable in the recess, said key having a beveled inner end adapted to lock with the said teeth, said larger diameter of bore extending to one end of the bracket, and said spindle having an annular flange bearing against the lower end of the bracket and closing said larger diameter of bore, substantially as described.

5. in combination, a bearing bracket, a spindle mounted to turn in the bearing bracket, an annular flange on the spindle, said spindle at its end having a longitudinal groove adapted to receive the inwardly bent end of a coiled spring, a circular series of ratchet teeth on the spindle located within the bearing bracket, a movable key adapted to lock with said teeth, said key having an enlarged inner beveled end adapted to engage with the teeth when the latter are turned in one direction and to be moved by the teeth when the teeth are turned in the opposite direction, and said spindle at one end projecting beyond the bearing bracket and made angular, substantially as described.

In testimony whereof I haye signed my name to this specification in the presence of two subscribing witnesses.
