UNITED@ STATES PATENT F'EI'CIEL" SWINGINGLDOOR CHEOK'.

Application fired June `1o, 1925.. semaine; 36,255

Beit known that we, KARL Linssen and VERNER BRYNGELsoN, citizens of the United States, residing a't Niagara, in the county of Marinette and State of Wisconsin, have invented new and useful Improvements in Swinging-Door Checks, of which the following is a specification. v

This invention relates to a door check, the general yobject of the invention being to provide a simple device for checking the swinging movement of a Idoor and one which will stand the strain imparted to it door which is in extensive use.

Another object of the inventiony is` to provide means whereby the check can be easily and quickly applied for use on a door which swings bot ways. This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, ilJ lustrated in the accompanying drawings and s ecifically pointed out in the appended c aims.

In describing the invention in detail, reference will be had to the accompanying drawingswherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation showing the invention in use.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a top plan viewV showing the door open.

` Figure 4 is a section on line i- 4 of Figure 2.

Figure 5 is a detail sectional view through the lower portion of the hinged part of the door.

In these views 1 indicates a door frame and 2 indicates the door, this door being provided with a hinge arrangement which will permit it to be swung in either direction.v The check for the door comprises an L-'shaped bracket 3 which is fastened to the door frame, an arm 4 which is pivoted to the outer end of the bracket and which has a flat portion 4 adjacent its outer end for engaging a part of the door and a spring 5 which connects the arm with the bracket and tends to hold the arm with a shoulder thereon against a shoulder on the bracket, these shoulders limiting the inward movement of the arm. In this position 'the arm will be bya resting against a -faceof 'the ffdoor with the door in clo"sedposition- In order to prevent wear on the door, a plate 6 is fastened thereto and the part 4 on the arm 4 engages said plate.

It will 'thus be seen that when the door is pushed open the part 4 will slide on the plate 6 and the movement of the arm on its pivot will stretch the spring 5 and thus the movement of the door is resisted by the spring. In this way the pressure of the arm on the door will check the opening movementl of the door and will also return the door to closed position after the force which opens the door is removed therefrom.

When the device is used on a door which swings in both directions, a bracket 7 is fastened to the arm and aI spring 8 connects said bracket to a bracket 9 on the door so that when the door is pushed away from the device, this spring 8 will be stretched and will act to return the door to closed position.

As will be seen, the device is very simple, contains few parts and the parts are of considerable strength so that the device can be used on a door which is used a great num ber of times. It can be easily converted into a check for a door opening in either direction.

The drawin s show the door as provided with a novel orm of hinge which consists of a rod-like member 10 connected with the rear edge of 'the door and having its upper end engaging a circular bearing hole 11 formed in a plate 12 fastened to the top of the door frame and its lower end engaging a bearing hole 13 formed in a plate 14 fastened to the door sill above a plate 15 which carries a ball 16 upon which the lower end of the member 10 rests. This provides a strong hinge which is supported upon a ball bearing with its end rotatably mounted in plates in the door frame.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

We desire it to be understood that we may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A door check comprising an L-shaped bracket adapted to be connected with a door frame, an arm pivoted to the outer end of the bracket and having its outer end adapted to engage a door, a Spring connecting the arm with the bracket, a projection on the arm and a spring connected with the outei` end of the projection and adapted to be connected with a door.

2. In combination with a barrier and its frame, an angle-shaped bracket connected with the frame, a. curved arm Jivoted to the outer end of the bracket and iaving a fiat W part on its outer end for engaging the barrior, a spring connecting the outer part of the man with the bracket, an extension on the arm, a spring connecting the outer end of the extension with the barrier, and` a wear plate on the barrier and engaged by the fiat pam of the arm.

In testimony whereof We aix our signatures.

KARL LIDBECK. VER-NER BRYNGELSON.
