' UNITED STATES PATENT @FFICE.

MARCIUS C. RICHARDS, OF AURORA, ILLINOIS, ASSIGNOR OF ONE-HALF TO THE WVILCOX MANUFACTURING COMPANY, OF SAME PLACE.

DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 444,019, dated January 6, 1891.

Application filed August 11, 1890- Serial No. 361,743- (No model.)

To a'ZZ whom it may concern:

Be it known that I, MARCIUS O. RICHARDS, residing at Aurora, in the county of Kane and State of Illinois, and a citizen of the United States, have invented a new and useful l'mprovement in Spring-Holders, of which the following is a specification, reference being had to the accompanying drawings,in which-- Figure l is a side elevation showing the holder unattached. Fig. 2is a side elevation showing the holder attached in position for use. Fig. 3 is a side elevation showing an entering device held by the holder, and Fig. 4. is a side elevation showing a modification designed to hold the handle of a broom or similar article. 1

My present invention relates to springholders designedfor holding entering devices secured to a door or the handle of a broom or similar articles.

The object of my invention is to provide an adjustable spring-holder whose tension may be adjusted as necessary; and it consists in a holder composed of two spring catcharms extending from a spring-plate which is arched outwardly in a direction toward the outer free ends of the arms in such manner that pressure exerted centrally on the arched plate by an attaching-screw or similar fastening operates to move the spring-arms toward each other, and thereby increase their tension or spring action on the part with which the spring catch-arms engage.

In the drawings, A A represent the spring catch-arms. These catch-arms, as shown in Figs. 1, 2, and 3, are made in proper form to receive and hold an entering device 13, such as that shown in Fig. 3.

When the device is designed to receive and hold the handle of a broom or similar article, the spring catch-arms A A are formed as shown in Fig. 4:.

The spring catch-arms A A are connected by an arched plate C, of spring metal, which projects outwardly in a direction toward the outer free ends of the spring catch-arms in such manner that pressure brought to bear on the center of the arched plate will throw the spring catch-arms toward each other and place them under increased tension.

When the holder is detached, it is normally in the form shown in Fig. 1, the curved portion C being curved inwardly to a considerable extent. The holder is adapted to be attached in position by an attaching screw or bolt D, which passes through the curved portion C near its center. By adjusting the screw dr bolt D more or less tension is given to the curved portion C and spring-catches A A. The attaching screw or bolt D being at the middle of the curved portion C and the spring-catches A A being integral therewith, the catches, while held firmly in position, are free to be sprung apart by the entering of the device 13 or other article to be held by the catches.

When the holder is used as a door-holder, the holder may be attached either to the door or to some stationary part, the entering de- Vice B being attached to the other part. When the holder is used for holding brooms or similar articles, it may be secured in any suitable position.

I am aware that spring holding devices have heretofore been used employing two spring-catches through each of which an attaching-screw is passed, which interferes with the spring action of the catches. By my de vice the catches are held in position by the screw or bolt at the middle of the curved portion, so that the'spring action of the catches is not interfered with and their tension can be adjusted.

The essential feature of my invention consists of the spring-armsA A, connected by an inwardly-curved portion C, whose ends bear against the support to which the holder is to be attached and whose middle portion is adapted to be attached by a bolt or screw to said support, so that by tightening or loosening the attaching screw or bolt more or less tension can be given to the spring-arms A, as fully illustrated in Figs. 1 and 2.

What I claim as new, and desire to secure by Letters Patent, is-- A spring-holder consisting of pair of spring catch-arms extending from a springthrow the catch-arms toward each other, and plate C and integral therewith, said plate hethereby increase their tension, substantially ing" arched outwardlyin a direction toward the as described.

outer free ends of the catch-arms and away MARCIUS C. RICHARDS. 5 from the snppcrtto which it is adapted to be Witnesses:

attached by a screw or bolt, by which pressure GEO. II. HALE,

is brought to bear on the arched plate to '1. II. DAY.
