Application filcclJanuary 29, 1924:. Serial No. 689,343.

To all whom it may ooncem:

Be it known that we, THOMAS O. THovsoN, Emma BRAY, CARL S. Brennan, and OLIVER BRAGER, citizens of the United States, residing at Hanlontown, in the county of lVorth, State of Iowa, have invented certain new and useful Improvements in Gate Latches; and we do hereby declare 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.

This invention relates to gates, and particularly to gates used in connection with hog pens and houses.

One object of the invention is to provide a device which will releasably hold the door of a hog house in closed position, against being moved into open position by wind.

Another object is to provide means by means of which, when the door, which door closes by gravity, reaches its full closed position, it will not have a tendency to swing back and forth, but will be properly held in closed position.

Another object is to provide a device of this character which will permit the door to swing open to its full position without interference therewith, but which will act upon the door, when said door is relieved from the opening pressure to more quickly restore the door to its full closed position.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation of a door, and its enclosing frame, equipped with the present invention.

Figure 2 is ahorizontal sectional View on the line 2-2 of Figure 1, the partially open position being shown in dotted lines.

Figure 3 is a vertical sectional view on the line 3-3 of Figure 1, one of the closing arms being in elevated position, and the door partly open.

Referring particularly to the accompanying drawing, there is shown a door frame including the top and bottom rails and 11, and the vertical side stiles 12 and 13, connected thereto. Secured to the stile 13, and extending between the rails 10 and 11, is an inverted right triangular member 14:, and carried by the upper end of this member is the stationary member 15 of the upper hinge, while the stationary memher to, of the lower hinge is carried by the lower end of said member, this latter nieinber 16 being also secured to the stile.

' conforming to the outline of the rails 10 and 11 and stile 12, while the fourth side is inclined in conformity to the edge of the member 14. By this construction, the door. which carries the other members 18 and 19. of the upper and lower hinges, respective ly, is adapted to gravitate to closed position withln the frame, when opened and released. The door, when swinging into closed position, will vibrate back and forth. before finally settling into position within the door frame, and it is with this difficulty in new that the present device is provided. It will be noted that the upper member of the hinge carried by the door extends longitudinally on the upper edge of the door. for a suitable distance from the member 14.

fiecured to the lower face of the upper rail 10, and extending transversely thereof. is a strip 20. and pivotally supported on each end of this strip, and depending against the face of the door, is an angular arm 22, the free end of which is directed toward the hinged edge of the door. These arms 22 are preferably of heavy metal. so that they will gravitate into depending posi tions, against the faces of the door, and also to act upon the door to move the same into full closed position, within the door frame. The free end of each arm 22 is adapted to be elevated when the door is swung into open position, and to ride on the door carried portion. of the upper hinge, which hinge portion serves as a wear plate to protect the door. 7

The positions of the hinges, of the door, causes the door to gravitate into closed position, when released, but due to the fact that the door will have a tendency to vibrate when in its nearly closed position. the weighted arms 22 are provided to overcome thls and cause the door to quickly settle into full closed position. Furthermore, the arms are of sufficient weight to resist the opening movement of the door under pressure of wind. The door may, however, be easily pushed into open position by the hogs, when passing into and out of the hog house. Thus the door will be held against accidental opening movement, so that drafts, within the house, will be prevented.

lVhat is claimed is:

The combination with a doorway and a gravity closing door mounted therein for swinging movement in opposite directions, of a transverse member secured to the upper portion of the frame 01 the doorway transversely thereof and above the said door, said member having bearing means on its opposite ends disposed beyond the side faces of the door, and an L-shaped arm pivotally suspended on each end of the transverse member and depending against the side face or the door, said arm being arranged to be swung upwardly by the door In testimony whereof, we afiiX our signatures, in the presence of two witnesses.
