Specification of Letters Patent.

Patented Dec. '7, 1909.

Application filed September 15, 1909. Serial No. 517,878.

To all whom t may concern:

5e it known that I, JOHN LYMAN WEBB, a citizen of the United States, residing at Oakley, in the county of Cassia and State of Idaho, have invented certain new and useful Improvements in Door-Stops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in door stops, and has for an object the arrangement of a stop which may resist any opening of the door, but not positively lock the same against movement.

Another object of the invention is the arrangement of a door stop that normally yieldingly resists the movement of the door, formed with means for readily throwing the stop out of operation.

A still further object of the invention is the arrangement in a door stop, of a spring pressed arm and pivotally mounted foot held in engagement with the iioor by the spring, whereby any excessive pressure on the door will cause the foot to turn over.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a fragmentary view of a door with a door stop embodying the invention applied thereto. Fig. 2 is an enlarged fragmentary edge View of a door with the stop applied thereto. Fig. 3 is a view similar to Fig. 2, except that the door has been forced in the direction of the stop. Fig. 4 is a view similar to Fig. 3 except that the door has been forced in a direction toward the stop until the stop has turned over. Fig. 5 is a detail fragmentary view of a slightly modified form of foot. Fig. 6 is an enlarged perspective View of the stop detached.

Referring to the drawing by numerals, 1 indicates a door of any desired kind, to which the stop is applied. The stop is formed with a foot or contact member 2 which is formed bifurcated, and is provided with teeth or roughened surfaces 3 and 4 in order to prevent any slipping of the foot. The foot 2 is pivotally mounted at 5 upon an arm 6 which in turn is pivotally mounted upon a plate 7. Plate 7 is rigidly secured -in any desired manner to door 1, and is formed with a turned over or eye portion 8, through which the end of arm 6 passes, and which forms a journal bearing therefor, whereby the pivot-al end 5 may swing around turned over or journal portion 8 upon the arc of a circle. Wrapped around the end of arm 6, which projects through the bearing member 8, is a spring 9. One end of spring 9 is fitted into a notch or aperture in the end of arm 6, and the other end bears against plate 7, whereby arm 6 is given a continuous tendency to move downward, so that when foot 2 has been raised from the floor, as shown in Fig. 4, the curved portion l0 will be pressing against an extension 11 projecting from plate 7 Pivotally connected to foot 2 at one end is a rod 12 passing through a guiding member 13 and formed t its upper end with a hook or thumb mem- In operation, after the stop has been placed l in position on the door, the door may be left at any desired position, and spring 9 will act against arm 6 for forcing foot 2 against the floor. Any slight pressure, as for instance wind pressure, against the door will not be able to move the door, but in case a person desires to open the door from the outside, (the stop being positioned on the inside), all that is necessary is to exert more or less pressure against the door, until the spring 9 is overcome and foot 2 is turned over, as shown in Figs. 3 and 4. I/Vhen the door has been forced open in this mannere foot 2 will remain in an inverted position, as shown in Fig. 4, until some one raises or pulls up member 14, which, acting through rod 12, will turn foot 2 over and upon releasing of member 14 spring 9 will force the bottom of the foot against the floor. In case anyone desires to open the door from the inside they may raise member 14 and pullv or push the door as desired without turning over foot 2.

In Fig. 5 will be seen a slightly modified form of foot 2 provided with rubber ends 3 and 4 instead of the notches or teeth 3 and 4 of the preferred structure.

What I claim is:

1. In a door stop, a foot formed with a bifurcated lower end, and friction members on the bifurcated lower end, a pivotally mounted arm for actuating said foot, a spring for actuating said arm, and a rod pivotally engaging one end of said foot for said foot at the end opposite the bifureateci Y portion, said rod being adapted to be 0p- 'erated 'for raising said foot against the ae- .tiQn of said spring.

In testimony whereof I aix my signature Iin l presence of tWo Witnesses.

2. In a door stop, a foot formed biur-' cated at one end, means arranged on .said bifureated end for preventing the slipping of said foot, an arm `pivotally kmounted on said foot slightly o-eenter thereof, a support in Which said arm is pivotally mounted, a spring acting on said arm for norma-ily Witnesses: causing the same to press Isaid ,oot .down- HENRY W.
