DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 689,152, dated December 17, 190 1.

Application filed October 2,1901. Serial No. 77,296. (No model.)

To all whom it may concern.-

Be it known that I, LEoNIDAs E. ANDERSON, a resident of Pittsburg, in the county of A1- legheny and State of Pennsylvania, have invented a new and useful Improvement in Door-Checks; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to door-checks; and its object is to provide a simple and convenient form of door-check which will efficiently retain the door in the position desired and which will not injure the carpet, tiling, or polished floor of the apartment in which the said door-check is used.

My invention comprises, generally stated, a door-check composed of a plate of resilient sheet metal having one end thereof bent or curved under on a circle, so as to form a rest which elevates that end of the door-check to form a gradual incline, with which the lower edge of the door engages, while at the same time said bent or curved under portion increases the resiliency of the check and also presents a smooth slightly-curved surface in contact with the floor, which will not injure or impair in any way the carpet, tiling, or polished wood, as the case may be.

My invention further comprises certain details of construction, all of which will be fully hereinafter set forth and claimed.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which- Figure 1 is a perspective view of my invention applied to a door. Fig. 2 is an enlarged sectional view of a portion of the door, showing my improved door-check in side view.

Fig. 3 is an enlarged side view, partly in section, showing my improved door-check raised by the auxiliary screw; and Fig. 4 is a perspective View of the door-check.

In the drawings, 2 represents a suitable door, and 3 the fioor of the apartment.

My improved door-check is composed of a plate 4, formed of metal of proper thickness and having the requisite resiliency. This plate may be plated with nickel or brass or ornamentedlin other ways, as may be found desirable, so as to presenta neat and finished appearance. Que end of the plate 4 is curled I or bent in under, as at 5, so as to form a rest or support for that end of the plate and give it the proper incline to act as a wedge on the lower edge of the door when in use. The end 5 is curled or bent under slightly more than a semicircle, so that when in use a smooth slightly curved or rounded face is in contact with the carpet, tiling, or polished wood, which will not mar or injure in any way the material of the floor. Furthermore, by bending the metal in the manner described more resiliency is given to the door-check, as pressure brought to bear upon the inclined surface of the check by the action of the door will cause the curved or bent portion 5 to yield, and consequently act to lock the door more securely in place.

In some cases where the sill of the door is of such height that the bottom of the door will not engage with the inclined face of the door-check with suficient resistance to lock the door in place an auxiliary support may be used, such as the screw 6, having the head 7, said screw passing down through the threaded collar or nut 8 on the plate 4 and having its end swiveled in the foot 9. It is the end of the plate will be elevated to lift the curved portion 5 above the level of the floor, as shown in Fig. 3, and to increase the incline of the check, so as to engage properly the lower edge of the door. The thread on the screw 6 is of such a pitch as to elevate the upper end of the door-check very rapidly, so that one turn will probably be sufficient to bring the check to the proper height.

My improved door-check is light and simple in construction, while at the same time it provides a positive check for the door in whatever position it is set, the resiliency of the curved portion 5 increasing its holding power and also increasing its durability.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A door cheek comprising a plate of spring metal having one end adapted to rest on the fioor and the other end curled or bent under on a circle to form a support for that end of the plate, said curled-under portion extending for slightly more than a semicircle, whereby a smooth, slightly-curved surface is presented to the floor.
