ELI W. IMLER, OF NELSON, NEBRASKA;
SPECIFICATION forming part of Letters Patent No. 435,226, dated August 26, 1890.
Application filed April 24, 1890. Serial No. 349,698. (No model.)
To all whom it may concern:
Be it known that I, ELI W. IMLER, a citizen of Nelson, in the county of Nuckolls and State of Nebraska, have invented certain new and useful Improvements in Door-Checks; 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 an improvement in door-checks, its object being to produce a door-check which shall be simple in construction, effective in operation, and cheap to manufacture.
A further object is to so construct a doorcheck that it shall be light in construction and easy of application to a door to maintain it in any desired position.
A further object is to provide a door-check which shall be capable of adjustment, whereby to adapt itto doors of different sizes and weights.
With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.
In the accompanying drawings, Figure l is a perspective view of my invention. Fig. 2 is a side elevation. Fig. 3 is a separate view of the spring. Fig. 4. is a view of a modification.
A represents a metallic plate, preferably of rectangular form and flat on its under face. The forward end of the plate is beveled to permit it to be readily inserted beneath a door, and this beveled end terminates at a point near the forward end of the plate in an enlargement or shoulder B, in which a recess a is made, for a purpose hereinafter explained.
In proximity to the rear end of the plate A a post C is located and made to project upwardly from the face of the body of said plate, and the shoulder or enlargement B being preferably cast 'or formed integral with the plate. The post 0 may be made extensible, as occasion requires, when desired to adjust the de Vice to doors of varying sizes and weights by means of one or more plates or blocks 1), se-' cured to the body of the post by means of a pin or other fastening device 0 The post C and the plate or plates b secured thereto are provided with aligned perforations (I, one near each end of the free ends of a wire spring D.
In making the spring D a piece of springwire of suitable size and length is first bent upon itself, and the bent portion is then bent slightly upwardly, as at e, the free ends of the spring being bent downwardly at or nearly at right angles to the body of the spring to produce arms f. The spring being thus formed, the end 6 thereof is inserted in the recess a in the shoulder or enlargement B, and main tained therein by means of a pin or screw g passing through a perforation g in said shoulder, the recess being of sufficient size to permit a slight movement of the end e of the spring therein when the device. is applied to a door. The pin or screw 9 may (if it be desired to secure the device in apermanent po sition) be extended and made to enter the floor, and the device may be further secured to the floor by means of a fastening device passing through a perforation h in the rear end of the plate. The portion 6 of the spring D having been inserted into the recess in the shoulder B and connected to the shoulderby means of the fastening device 9, the members i 'i of said spring are made to cross each other, as shown in Figs. 1 and 3, and the arms f inserted in the perforations in the post 0. By thus constructing and attaching the spring D to the plate it will be seen that when the device is applied to a door the spring will exert a double pressure at the point where the wires cross. A side as well as an upward pressure will be exerted by the spring when it is engaged by the door at or near the point of crossing of the members z'.
In order to prevent the check from slipping when used to temporarily maintain a door in an open or partially-open position, pointed tangs or barbs E are made to project from the bottom of the plate A and adapted to enter the floor when the device is engaged by the door.
In lieu of producing the portion 6 of the scribed a door-check will be produced which will be simple and cheap and light in construction, easyto manufacture, and efiective in operation.
5 Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A door-check consisting of a plate having a projection at or near each end and a 10 spring connected to said projections by being secured to one and passing loosely into the other, substantially as set forth.
2. The combination, with a plate having a shoulderat one end anda sectional post at or I5 near the other end, of a spring, said spring being bent upon itself and connected at the
