' Specification of Letters Patent.

Patented Sept. 24, 1918.

Application filed. November 27, 1916. Serial No. 133,602.

To all whom it may concern: 1

Be it known that I, ROBERTS. LAVENDER, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Door-Fasteners; 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.

My invention relates to means for fastening doors in the opened position.

The object of my invention is to produce a simple, cheap arid eflective device for fastening doors in the opened position, which device shall be capable of being placed in an unobtrusive position and which shall not fasten the door unless it is desired to fasten the same, but which shall at all times serve as a stop for the door in the open position in order to prevent the latter from striking and marring chair boards, walls, etc.

A further object of my invention is to provide such a fastener which can be moved into engagement with the door and disengaged therefrom by simple motions of the foot.

In carrying out my invention, I make use of the instrumentalities illustrated in the following figures; in which,

Figure 1 is a perspective view showing a portion of the floor, a chair board, door jamb and door with my improved door fastener applied thereto, the door being in the opened position and fastened.

. Fig. 2 is an enlarged view similar to Fig.

1, but omitting the floor, chair board and door jamb.

Fig. 3 is a plan view of a portion of a door in theopen position showing the manner in which my improved fastener serves as a door stop.

Fig. 4 is a section of the floor and my improved door fastener along the line 44 7 in Fig. 1 and looking in the direction of the arrow 4 in said figure.

10 represents a floor, 11 is a chair board, 12 is a door jamb and 13 is a door, all of these parts being of the ordinary construction and forming no part of my invention. 14 represents the door fastener, which comprises the body portion 15 provided with a hole 16.

A screw 17 has its body portion passing loosely through the hole 16 and its threaded portion is screwed into the floor 10, as shown .in Fig. 4.

A washer 18 is placed between the head of the screw 17 and the body 15, and a second washer 19 is placed between said body portion andthe floor 10.

The washer 19 is to be made of any height so that the under side of the door fastener 14 may clear rugs, carpets, mattings, etc., that may be upon the floor.

The door fastener also comprises a lever portion 20 which extends to one side of the body portion 15 and terminates in a nose 21 having a curved surface 22 inclined to the lever portion 20 and a surface 23 at right angles thereto. To the flat surface 23 I preferably attach a felt pad 24 for a purpose hereinafter referred to.

The body portion 15 is provided with a curved surface 25 where it joins the lever portion 20 and I mount a rubber, felt, or other buffer 26 on said curved surface for a purpose hereinafter referred to.

The operation of my improved door fas tener is as follows:

The door fastener 14 being attached to the floor by the screw 17 in proximity to the chair board, as shown in Fig. 3 and being allowed to rest in the position shown in full lines in said figure, the door 13 can be opened and shut without bringing the door fastener 14 into fastening relation with the door 13, but during this mode of operation of my improved fastener, the bufler 26 will serve to limit the movement of the door and prevent it from striking the chair board 11, consequently my improved fastener thus operates as a door stop.

It is also evident, by reference to Fig. 3, that the corner 27 of the body 15 will strike the chair board 11 and prevent the nose 21 from moving further toward the left than is shown in said figure.

When it is desired to fasten the door in the open position, the nose 21 is to be moved to the position shown in full lines in Figs. 1 and 2 and in dotted lines in Fig. 3. This can be done either by the hand or foot. When the nose 21 has been moved as just described, the pad 24 and the buffer 26 will embrace the sides of the door and prevent same from moving.

It is evident by an inspection of Fig. 3, that the corner 28 of the body 15 will strike the chair board 11 when the nose 21 is moved to the position shown dotted in said figure, consequently should the nose 21 be so moved While the door is closed and the door afterward be opened, the corner 29 of the door Will strike the'curved surface 22 of the nose 21 and move the same approximately to the position shown by full lines in said figure, thus permitting the door 13 to strike the buffer 26 Without-producing any undue stress on the nose 21.

I claim:

The combination With a floor, a door, a chair board and a screw secured in said floor, of a door fastener pivotally mounted on said screw, said door fastener comprising a body portion provided With a hole for the reception of said screw, a lever portion, a nose portion provided With a flat surface for holding said door and a curved portion for moving said nose out of the path of said door, said body portion having a curved surface and a buffer mounted thereon for stopping said door, said bufier being so located that the contact of said door therewith does not move said fastener to lock said door, and corners on said body portion located to strike said chair board and limit the movement of said door fastener.

In testimony whereof I affix my signature.

ROBERT S. LAVENDER.
