DOOR-CHECK.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed April 25,1905. Serial No. 257,296.

To all whom it may concern:

Be it known that 1, CHARLES MoGINNrs, a citizen of the United States, and a resident of El Paso, in the county of El Paso and State of Texas, have invented a new and Improved Door-Check, of which the following is a full, clear, and exact description.

This invention relates to improvements in checks for swinging doors, the object being to provide a device of this character that will be simple and inexpensive in construction, that may be easily applied to a door, and by means of which the door may be held at any desired opening or permitted to slowly close without slamming.

I will describe a door-check embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming-a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a front view of a door-check embodying my invention and showing the same as attached to a door. Fig. 2 shows the check in top plan. Fig. 3 is an elevation of a locking-rack employed. Fig. 4: is a bottom plan of a cushion employed, and Fig. 5 is an elevation of the device partly in section.

It may be here stated that the device is to be attached to the lower portion of a door near the locking edge and on the side in the direction of which the door swings for opening.

The device comprises a single length of spring-wire having an upper member 1 and a lower member 2. These members are spaced apart, and their connection is made in the form of a coil 3, which engages around a stud 4:, so as to have slight rotary motion thereon. This stud is provided with outwardly-extended wings 5, provided with perforations through which screws pass to secure the lug to a door.

To raise the fastener to upper or normal position, as will be hereinafter described, I employ a spring 6, having two members, between which is arranged the upper member 1, and these side members are provided with spring-coils 7, and the ends are passed into perforations in the lug or stud 4. The cross member of this returning-spring 6 engages against the under side of the upper member 1 of the check.

Secured to the door is a. locking device for the check. This locking device consists of a rack 8, the lower sides 9 of the teeth being inclined upward and inward, so that the member 1 cannot readily or accidentally slip out from engagement therewith. The upper edges of the teeth are inclined downward. as indicated at 10, so that by foot-pressure on the outer end of the upper member the check may be readily forced downward, the said upper member 1 being provided with a ring 11 at its end, which forms a foot-plate. The lower member 2 has a portion extended into an opening 12, formed in a sliding part 13, the upper and lower walls of which are divergent from the center outward in both directions, so as to permit a free sliding movement between the parts. On the lower end of the part 13 is an enlarged block 1 1, slidable in a boxing 15, secured to the door and open at the bottom. At the top the boxing has an inwardlyturned flange 16 for engaging with the upper end of the blocks and preventing it moving too far upward. Seated in the lower end block is a rubber cushion 17, having an H- shaped surface 18 for engaging a floor or carpet. It will be noted that as the end members of the spring 6 pass into the stud 4 at opposite sides of the coil 3 the said coil cannot slip otfthe stud.

In the operation when it is desired to hold the door at any opening foot-pressure on the ring 11 will force the two members 1 .Zdownward, so that the cushion will engage against the floor or carpet. The pressure on the floor or carpet will be regulated by the degree of downward movement of the upper member1 that is, depending upon which one of the rackhooks is engaged thereby. Therefore it is evident that the pressure may be regulated to hold the door firmly open or to permit it to gradually close. To release the device from engagement with the floor or carpet, the member 1 is to be moved slightly downward by foot-pressure to disengage it from a hook of the rack. Then upon releasing the pressure the spring 6 will return the parts to upper or normal position.

While Ihave described the device as a doorcheck, it is obvious that when the door is closed the device may be forced tightly into engagement with a door-sill or the like, and thus form an auxiliary lock.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A door check comprising upper and lower connected members. a stud on which the two members are mounted to turn, a part operated by the lower member for engaging with a floor, and a locking device for engaging with the upper member.

2. A door check comprising upper and lower connected members, a stud on which the two members are mounted to turn, a spring on the stud engaging with one of the members for moving the parts to normal position, the said lower member having connection with a device for engaging with a floor or the like, and a rack for engaging with the upper member.

3. A door-check comprising a single length of spring-wire bent to form upper and lower members having a coil connection, a stud for engaging in said coil connection, a sliding device with which the lower member connects, an enlarged block at the lower end of the sliding device, a boxing in which said block is movable, and a locking device.

4. A door-check comprising a single length member, a rack with which the upper member is designed to engage, and a foot-plate at the end of said upper member.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES MOGINNIS.
