V DOOR-STOP.

Specification of Letters Patent.

Patented Mar. 15, 1921.

Application filed December 26, 1918. Serial No. 268,288.

To all whom it may concern:

Be it known that I, NATHANIEL CRANK, citizen of the United States, residing at Hill City, in the county of Graham and State of Kansas. have invented certain new and useful Improvements in Door- Stops, of which the following is a specification.

This invention relates to door stops, and belongs to that class of devices for holding doors open against accidental displacement, such devices being customarily operated by the foot.

The object of this invention is the production of a door stop or holder having special construction and arrangement of its component parts, which is to be secured to the floor in the path of a door when opening, and which will be operated by the open. ing door to catch and hold the door, and. which may be released by the foot of the operator when it is desiredto close the door. It i believed that a door stop made in ac cordance with this invention may be very cheaply manufactured, and at an unusually low cost.

The accompanying drawings set out the construction and arrangement of the parts of this invention as it is preferred to fashion and dispose them, and Figure 1 repre sents a side view of the lower corner portion of a door held open by the application of this invention. Fig. 2 is a horizontal section of the door as shown in Fig. 1, and includes a plan view of this invention holding the door in open position. Fig. 3 is a horizontal section of the door as in Fig. 2, and shows the door swung partly open, and illustrates the position of a door stop made in accordance with this invention and which has been revolved horizontally by the handor foot to release the door. Fig. 4 is a front view of a door stop made in ad cordance with this invention. Fig. 5 is a top plan view. Fig. 6 is a side view. In Figs. 4, 5, and 6, the scale of drawings has been increased to more clearly illustrate this invention.

Throughout the drawings and description the same letter is employed to refer to the same part.

Considering the drawings, the door A swings in the usual manner near the floor a. Upon the floor is a floor plate B, usually circular in form, and riding upon the floor plate is a base plate 6 that is pivotally secured upon the floor plate by means of a pivot pin 0.

hirected upon the base I) are two vertical a ls D and (Z. These walls are customarily parallel as set forth, and they are joined at the bacl: by the rear wall E. As best shown in Fig. 4, the ends 'of the back or rear Wall E, marked F and f, extend outwardly beyond the ends 01": the vertical walls D and (Z and form wings projecting outwardly from those walls. Une among the advantages of having the wings F and 7 project well be yond the base plate and the floor plate as illustrated is that the stop is readily found and released by the foot in the darkness. By sliding the foot along the lower edge of the door in contact with the floor, the foot is guided directly against the proper wing and the stop released. The necessity for having two wings is to provide for doors which are swung to open in different directions, so. that one wing will always project out-- wardly from the surbase of the wall of the room.

A. stop pin (5? limits the rotation of the base I) in one direction.

The operation of this invention is thought to be readily discernible from the drawings and the foregoing description.

When the door stop is positioned upon the floor illustrated, and as set forth in Fig. 3, the door A may be swung in its opening movement so that the edge of the door will enter between the vertical walls, and the continued opening movement of the door will bring the door and the door stop into the relative positions set forth in Fig. 2. N ow, the door is held against displacement in either closing or opening directions. But, if the wing 7 be pressed upon by the foot of the operator, the base 5 and parts carried thereby will be swung again into the positions illustrated in Fig. 3, and the door may now be opened, and the door stop left in the position for engaging the edge of the door when it is again opened.

Having now described this invention, and explained the mode of its operation, what I claim is The combination with a-fioor plate, of a base plate pivotally mounted thereon, side walls erected upon the base plate and spaced apart, and a rear wall connecting the side walls, the ends of the rear wall projecting beyond the side walls for the purpose specified forming wings, and the said wings projecting beyond the base plate.

In testimony whereof I afiix my si NATHANIEL CR ature.
