SYVER LOE, OF LA CROSSE, IVISGONSIN, ASSIGNOR OF T\VO-THIRDS TO MONS ANDERSON AND JAMES H. LIGI-ITBODY, BOTH OF SAME PLACE.
DEVICE FOR CLOSING DOORS.
SPECIFICATION forming part of Letters ?atent No. 429,278, dated June 3, 1890.
Application filed March 27.1890. Serial No. 345,556. (No model.)
To all whom it may concern:
Be it known that I, SYVER LOE, a citizen of the United States, residing at La Crosse, in the county of La Grosse and State of WVisconsin, have invented certain new and useful Improvements in Devices for Closing Doors, of which the following is a full and clear description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a perspective view of a door with my improvements attached. Fig. 2 is a horizontal sectional view of the same on an enlarged scale.
My invention relates to means applied to doors for holding them open and closed; and the same consists in the constructions and combinations of devices which I shall hereinafter fully describe and claim.
To enable others skilled in the art to make and use my-invent-ion, I will now describe its construction and indicate the manner in which I have carried the invention out.
In the accompanying drawings, A repre- 2 5 sents a door frame or casing, and B the door hinged thereto in any suitable manner. Se-
cured to the door, and preferably near the center thereof, are boxes or bearings a,
adapted to receive the ends or trunnions b of a U-shaped bail C, whereby said bail may have a rocking movement. In the outer curved end of the bail O, which extends at right angles to the door, is made an opening or perforation I), through which a rod D is 5 passed, and has its inner end threaded to receive a nut 0, while its outer end is formed with an eye (1, adapted to have fitted to it the outer ends of two rods E and E, one of which E extends inwardly at an angle and has its inner end pivotally fitted to an eye e,
secured to the door frame or casing or to a fixed part adjacent to the hinged side of the door, while the other rod E also extends from the eye d of the rod D inward at an angle 5 opposite to the angle of the rod E and has its inner end secured pivotally to an eye 9 near that side of the door opposite to the hinges, as shown in Fig. 1.
On the rod D, between the curved portion of the bail and the nut c, is a coiled spring G, whose tendency is to draw the rod D inward and whose tension is regulated by the nut c on the threaded end of the rod D. From this description it will be seen that when the door is closed the spring draws the rod D inward, which movement is communicated to the rods E and E, and as one of said rods is secured to a stationary portion-- 2'. e., the door frame or casingit is manifest that this inward movement of the rod D causes the rod E, which is secured to the door, to hold the door tightly closed. hen the door is moved from its closed position to an open position, the first movement of the door is transmitted through its rod E to the rod D, and this latter rod is forced outward against the pressure of its spring, and the bail is caused to rock slightly in its bearings. When the door assumes a position at about right angles to its casing, or, in other words, 7: when the door is about half-way open, the center of movement or dead-point of the door is reached, when the spring G draws upon the rod D and throws the door further open and until the rod E strikes aportion of the door frame or casing, when its further movement is checked and the door securely held open by the power of the spring. To again'close the door, the latter is moved until the dead-point is again reached, when the spring operates in the manner just described to throw the door forward and to then hold it in a securely-closed position.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. lhe combination, with a door, of a rocking projection therefrom having a rod D moving within it, a spring connected with the rod and normally drawing the same in- 0 ward, a rod pivotally connected with the rod D and with the door 011 one side, and a connection between the rod D and the door frame or casing, substantially as herein described. 5
2. The combination, with a door, of a U- shaped bail journaled thereon and extending outwardly at right angles to the door, a rod D, mounted to move in said bail, a spring tending to draw the rod inward, and rods con- Ioo nected with the outer end of the rod D and extending inward at angles opposite to each other, one of said rods having its inner end attached to the door and the other having 4. The combination, with the door, the U- shnped bail jenrnaled thereon, and the rods la and E, of a threaded rod 1), connected with 1 the rods E and E and adapted to move in I the bail, a spring surrounding the rod, and a 1 t nut; 011 the threaded end of the rod and bearing against the spring; to regulate the tension 20 thereof, substantially as described.
