DOOR CHECK AND HOLDER.

Specification of Letters Patent.

Patented Aug. 4, 1914.

\ Application filed November 22, 1913. Serial No. 802,359.

Improvements in Door Checks and Holders and I do dec are 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain improvements in door checks and holders and has for its object to provide an efiicient and otherwise satisfactory device for preventing the slamming of doors and for holding them closed, as will hereinafter more fully appear from the description to follow.

In the accompanying drawings, Figure 1 is a sectional new of adjacent portions of a door frame and door showing in top plan view my improved door check and holder, the door in this view being shown in a closed posit-ion; Fig. 2 is a similar view showing the door in the act of closing; Fig. 3 is a detached view of the roller frame and roller; Fig. 4 is an elevation of the roller with the spring portions or coils of the frame shown in section; and Fig. 5 is a detached elevation of the roller track or plate.

In a detail description of the invention,

similar reference characters indicate corresponding parts in the drawings and speci fication.

My improved door check and holder consists of two primary co-acting members, one

consisting of a suitable anti-friction roller- 1 which is suitably mounted upon the transverse part of two integral arms 2 which are integral parts of a frame 3 that is attachable to a door 4 in suitable osition as shown in Figs. 1 and 2. It is deslrable that the roller be mounted as near the vertical edge of the door as practicable. The frame 3 and arms 2 are provided with an intermediate spring consisting of coils 5 which transmit a force to the roller throughsaid arms. A bar 6 passes through sai spring coils 5 havin eyes in its ends through which screws pass to secure the roller frame to the door. There is also a third screw 8 which passes through an eye in one terminal of the frame and by means of which three points of attachment are provided for securely fixing said roller frame to the door. I The spring portions 5 have the requisite strength to maintain the door in a closed position as is shown in Fig. 1 against any resistance less than that which is required to open the door forthe purpose of ingress or egress. Constituting the other member and cooperating wit the roller 1 is the buffer plate havng an incline track portion 9 and a pocket or recess portion 10 to receive the roller after it travels over said incline. track portion. This cooperating buffer plate is secured to the door frame at bothends b means of screws 11 and a portion of the uoor is suitably recessed as at 12 in order to permit said door to close against the jamb. As

before stated, the spring portion ofthe rollerv frame is essentially strong in'order that the door may be held in a closed position when the roller enters the recess or pocket 10 of the butter plate. Owing to this necessary strength of said spring, it is desirable that the roller in entering the recess 10 from the incline track portion 9 shall meet with sufficient resistance to prevent a too forcible entrance of said roller into the recess, and owing to the resistance offered by the outer wall of said recess to the passing out of the roller in opening the door, a buffer or ring 13 is provided. This spring 13 may a of any suitable form. In the drawings, I have shown it to be in the form of a plate spring which is attached at one end to the roller track 9 and lies along the under side of said roller track and engages the surface of the roller through a slot 14 in the recess or pocket ortion. In Fig. 1, this buffer spring 13 is sliown as pressed outwardly by the roller 1 the latter having entered the recess 10-and owing to the strength of the spring portions 5 of the roller frame being greater than the tension of the bufl'er spring 13 the latter is forced outwardly. In Fig. 2, it will be seen that the roller is travelin up the incline portion 9 of the rollertrac This operation takes place as the door is being closed. Whenthe roller arrives at the recess 10, it enga es the buffer spring 13 and the latter, yiel ing, permits said roller to enter said recess with a cushion-like resistance only.

Having described m invention, I claim.

1. A door check and older, comprising in combination, a roller, a frame upon which said roller is mounted having intermediate portions which provide springs for said roller, means for attaching sald roller frame to the door, a buffer plate constituting atrack attachable to the door frame and constantially as specifiedf- 2. In a door check and holder, in combi nation with a roller, a frame adapted to be attached to a door and. upon which said roller is mounted, said frame having resil ient portions, a bar extending through said resilient ortions and providing means for the attac ment of said frame to a door, a roller track having inclined and recessed portions over and into which the roller passes, the recessed portion of said track aving an opening therein, and a resilient member constructed and arranged to engage the roller through said opening and to offer resistance to the entrance of said roller in said recess.

In testimony whereof l afiix my signature, inpresence of two witnesses.
