ALFRED JAMES PURVIANGE AND CHRISTIAN HILLS, OF KEOKUK, IOWA.

DGQR CHECK.

SPECIFICATION forming part of Letters Patent No. 392,688, dated November 13, 1888.

Application filed July 30, 1888. Serial No. 281,362.

To all whom it may concern:

Be it known that we, ALFRED J AMES PUR- VIANCE and CHRISTIAN HiLLs, citizens of the United States, residing at Keokuk, in the county of Lee and State of Iowa, have invented a new and useful Improvement in Door-Checks, of which the following'is a specification.

Our invention relates to improvements in door-cheeks, having for its object to provide a simple, cheap, and durable stop, which may be readily affixed to any door without previous preparation thereof.

A further object of the invention is to provide a door-check which combines therewith the advantages of a door-stop.

Theinvention consists in a certain novel construction and arrangement of devices, fully set forth hereinaftcrin connection with the accompanying drawings, and specifically pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of the improved door-check applied in operative position to a door. Fig. 2 is a longitudinal sectional view of the check. Fig. 3 is a bottom plan view of the same. Fig. 4 is a transverse section on the line 00 m of Fig. 3.

Referring by letter to the drawings, A designates a crescent-shaped wear-plate, which is secured by means of screws to a to the door B, and O designates a swinging bar, which is provided near its center with a depending ear, D, which is pivoted to the said wear-platc,thereby eccentrically pivoting the swinging bar to the door.

In a longitudinal slot, E, at the outer end of the swinging bar is arranged a transverse rod, F, to which is attaehedthe end of a contract ile spring, G, and the opposite end of this spring is attached to a stud, II, on the inner end of the wear-plate. This spring passes under the swinging. bar above the pivot of the ear D, and therefore the outer end of the bar is drawn upward and the inner end thereof bears tightly on the stud H. If, however,the outer end ofthe swinging bar is depressed suffc ciently to bring the line of the tension of the spring below the pivot of the ear D, the spring will draw the said outerend of the bar down wardtowardthefioor. Thusthisspringserves to hold the barin either the raised or the do- (No model.)

pressed position, according to the position of the pivot of the swinging bar in relation thereto.

The outer end of the swinging bar is provided with the adjacent parallel jaws K K, (inclined to the swinging bar,) between which is arranged the transverse pivot I, and L repre sents an elastic rubber of any suitable material, which fits snugly between the said jaws, and is mounted on the pivot I. This rubber is capable of a slight rotary movement around its pivot, but is not capable of complete revolution.

The front side of the bar 0 is provided with a depending web, III, which covers and pro tects the spring and gives the door-check a neat appearance; and N represents the doorstep, which is provided with a threaded stud,

a, on its inner end, which is screwed into a tapped aperture, 1;, in the said depending web. The outer end of this stop is provided with an elastic cushion, O, which is adapted to strike against the skirting or base-board when the door is opened.

IVhen it is desired that the doorswing freely, the outer end of the swinging bar is elevated until its inner end bears on the stud H, and it will be firmly held in this position by thespring until depressed sufficientl y to bring the spring below the pivot of the ear D. When it is desired to check the door, the outer end of the swinging arm is depressed, (by pressing the foot thereon,) when the rubber attached there to will be pressed by the spring firmly on the floor, thereby preventing the door from swinging freely.

It will be noted that when the swinging bar is in its engaging or checking position it is inclined to the floor, whereas the parallel jaws on its outer end are perpendicular to the floor, thereby causing the pressure of the rubber to be vertical.

By providing the improved door-check with a door-stop adapted to strike the skirting 0r base-board when the door is opened, all necessity for a supplemental device for the purpose of stopping the door is obviated, as will be evident.

Having described our invention,we claim- 1. In a doorcheck, the combination of the swinging bar provided with a depending pivoted ear, D, the stationary stud H under the inner end of the said bar, and the contractile of the door-stop N, provided with a threaded [5 spring attached at one end to the said stud stud, n, on its inner end fitting in a tapped and at the other end to the outer end of the swinging bar, whereby the line of tension of the spring is either above or below the pivot of the ear D, according to the position of the free end of the swinging bar, substantially as specified. v

2. In a door-check, the combination, with a swinging bar, 0, provided with a depending web, M, on its outer side, and having a suitable rubber on one end adapted to bear on the floor, and the spring arranged in rear of the said web and connected to the swinging bar,

aperture, n, in the web M, and the elastic cushion O on the outer end of the said stop, substantially as specified.

In testimony that we claim the foregoing as 20 our own we have hereto aflixed our signatures in presence of two witnesses.
