DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 493,112, dated March 7, 1893.

Application tiled October I 1892. Serial No. 448,466. (No model.)

To all whom t may concern.-

Be it known that I, JAMES S. PATTEN, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have in- 5 vented certain new and useful Improvements in Door-Checks, of which the following is a specification.

Myinvention has for its object to provide a simple and inexpensive door check, and stop,

ro and it consists in the novel arrangement and combination of parts hereinafter fully described in the specication and pointed out in the claims, reference being had to the accompanying drawings, in which, Figure l, is a perspective view of my improvement showing it applied for use. Fig. 2, is a side elevation of the same, showing the door held to a` checked position. Fig. 2, is a similar View of a modified form of zo holder. Fig. 3, illustrates the position of the cushion or holder, as the door is started in its movement to a closed position. Fig. 4, is a similar view illustrating the position of the holder during the final movement of the door to a closed position. Fig. 5, is a View illustrating the position of the holder as the door is started to an open position. Fig. 6, illustrates the position of the holder when it acts as a stop and, Fig. 7, is a transverse section 3o of my improvement on the line 7-7 Fig. 2.

In the accompanying drawings, A, indicates the securing plate which is secured to the door in the ordinary manner, and, may in practice be held for a slight vertical adjustment thereon, and such plate, has an outwardly extending arm a, formed at its outer end with a lateral stud or pintle a', as shown.

B indicates the elastic stop or holder, which is pivoted eccentrically upon the stud a. This 4o holder B, is substantially a crescent shape, the ends of its points being rounded to form contact members b b. This holder, as will be noticed by reference to Fig. 2, is pivotally connected to the plate A, in such a manner that its members b b will be forced into a tight frictional contact with the floor when turned to the position shown in the said tigure, and, when in this position the door will be securely checked from ordinary movement. When, however, the door is to be moved to a closed position (indicated by the arrow in Fig. 2) a suflicient pressure is applied to crowd the member b, between the stud a, and the iioor, (see Fig. 3) which causes the holder to turn on its axis until, it as'- 55 sumes the position shown in Fig. 4; when in this posit-ion it is loosely drawn over the floor, its peculiar connection with the arm ahold ing it from further rotation during such final movement of the door. When the door is 6o moved to its open position, the member b will again catch against the floor and cause the holder B to turn until both members again engage the floor, after which, the member b', will be forced under the stud, as shown, in Fig. 5, after which, it, (the member b) will be dragged over the tioor in a position reverse to that shown in Fig. 4. The upper face of the holder B, is projected beyond the outer end of the arm a as at B2, and forms a cush- 7o ion stop when the door is swung back against the wall, as shown in Fig. 6.

From the foregoing description, taken in connection with the drawings, it will be observed, that, by constructing the holder with 7 5 f two contactv members arranged at opposite sides of its axis, andeccentrically pivoting it,

to the stationary support A, positive means are provided for holding the door checked at almost any point, such operation being ef- 8o fected by simply, slightly, pulling or pushing the door until the members b, b', are both brought into contact Awith the floor.

While I prefer to form the elastic holders, crescent shape, as shown, it is manifest that a disk BX, (see Fig. 2a) having a tread or cut away portion bx, extending to each side of the axis may be employed.

Having thus described my invention,'what l claim, and desire to secure by Letters Pat- 9o ent, is- ,J

l. A door check comprising a securing plate having a horizontally projecting arm, an elastic disk eccentrically pivoted on suph arm and having a flattened contact portion extended to each side of the axis of such disk, whereby stop faces at opposite sides of such pivot are provided when such contact portion is turned to engage the oor; substantially :is centrally of and above the stopsb bell arand for` the purposes described. ranged substantially as shown and for the pur- 2.
