3 Claims. (01. 292-204) This invention relates to improvements in closure securing devices and pertains particularly to an improved latch for doors or similar closures.

The primary object of the present invention is to provide an improved latch structure designed primarily for use upon barn or shed doors or other heavy types of doors which may be effectively actuated either from the inside or the outside of the door and which is designed to 10 allow for a slight movement of the door under applied pressure whereby the breaking or otherwise damaging of the holding means is prevented.

Another object of the invention is to provide an improved type of oscillating latch for barn doors,

shed doors or doors of other structures, which comprises a rigid bar mounted for oscillation to operative or inoperative position and also having a slight movement toward or away from the door and adjacent jamb whereby, when the device is applied to a barn for example, the application of pressure to the inside of the door by animals within the structure will be ineffective to damage the latch whereas if a securing means of the usual hook and staple type were employed the same would probably be broken or otherwise damaged.

The invention, will be best understood from a consideration of the following detailed descrip-. tion taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a View in elevation of the latch embodying the present invention showing the same applied;

Figure 2 is a sectional View on the line 22 of Figure 1;

Figure 3 is a sectional view on the line 33 of Figure 4 is a sectional 'view on the line 44 of Figure 2.

Referring now more particularly to the drawing, wherein like numerals of reference designate corresponding parts throughout the several views, the numeral l represents a portion of a door jamb while a portion of the adjacent door is indicated by the numeral 2. The jambxportion of the door structure is shown as including the usual vertical posts at the inner side of the wall,

adjacent which the front edge of the door 2 positions when the door is closed.

The latching device embodying the present invention comprises the long flat latch bar 4 which is provided adjacent one end and upon one flat face with the staple 5 while at the opposite end and upon the same face there is secured the pin 6 which constitutes a means of taking a hold upon the bar for the purpose of oscillating the same in the manner hereinafter to be described. a 10 Intermediate its ends the bar 4 is provided with an aperture 1 which is of polygonal cross section as illustrated and passingthrough this aperture is the shaft 8 which is of a cross sectional design corresponding with the aperture 1 15 so that rotation or oscillation of the shaft about its long axis willefiect corresponding oscillation of the latch bar 4.

One end of the shaft 8 is of circular cross section and threaded, as indicated at 9, to receive a 20 nut l0 and encircling the shaft and disposed between the nut I0 and latch bar 4 is a coil spring H which is constantly under tension when the device is in use, tending to expand to force the latch bar and the nut Ill apart. 25

Upon the opposite side of the latch bar 4 from the spring II are the two washers l2 and i3 and secured to the other end of the shaft 8 isthe handle 14 which, as' shown, has a collar l5 to receive the end of the shaft and this collar car- 30 ries a set screw 16 which engages the shaft 8 to secure the handle thereto. i

In installing the latch, the stud and adjacent portion of the building wall which form the jamb for the front edge of the door 2, are provided 35 with a circular aperture l1 through which the shaft 8 extends, the washer I2 being disposed upon the outer side of the jamb and the washer l3 upon the inner side thereof as illustrated. The latch bar 4 is disposed against the outer face of 40 the wall I so that the end thereof which carries the handle 6 may be disposed across the outer face of the door 2 when the latch is in door securing position. It will thus be seen that the handle pin 6 provides a means for oscillating the latch from the outside of the door and the handle l4 provides means for oscillating the latch through the medium of the shaft 8, from the inside of the structure.

' On the outer side of the wall I adjacent the end of the latch bar 4 which carries the staple, when the latch bar is in horizontal position, there is secured a hasp l8 which may be provided with a suitable slot or recess to receive the staple 5 55 so that a suitable lock may be applied to hold the latch bar 4 in door securing position.

From the foregoing description it will be apparent that the latching device herein described will firmly hold the door 2 in closed position and because of the spring I I will not permit the door to move under the influence of light pressures such as might be applied by airdrafts. However, in the event of the application to the inside of the door of a heavy pressure, such as may sometimes be exerted by animals loose within the barn to which the device is applied, the door may move outwardly slightly against the tension of the spring II but as soon as the pressure is removed the spring will exert its influence to return the door to closed position.

I claim:

1. A door securing latch comprising a shaft designed to be mounted for axial oscillation in a wall adjacent to and in transverse relation with the edge of a door, a bar member having the shaft extended therethrough, the bar being slidable on the shaft but held against rotary motion thereon, spring means encircling the shaft and secured at one end thereto and having its outer end bearing against the bar to force the latter against the adjacent face of the wall, handle means carried by the bar at one end, a staple carried by the bar at the other end, and a handle carried by the shaft upon the end at the side of the wall opposite from the spring.

2. A latch for a door having a jamb or similar structure adjacent an edge thereof, comprising a shaft adapted to extend through the said structure for oscillation therein, a handle carried upon an end of the shaft upon the inner side of the door, a bar having the shaft extending through the transverse center thereof and adapted to position against the outer side of the door and structure, said bar being movable longitudinally on the shaft but held against oscillation independently thereof, a pin projecting from one end of the bar forming an outside handle, a hasp engaging staple carried by the bar at its other end, a spring surrounding the shaft between the bar and the end of the shaft remote from the first handle, and means carried by the last mentioned end of the shaft for maintaining said spring under tension.

3. A door securing latch, comprising a shaft designed to be axially oscillatably mounted horizontally ina wall adjacent to and in transverse relation with an edge of a door body, a latch bar connected with the shaft on one side of the wall and having movement longitudinally of the shaft but held against rotation thereon, means carried by the latch bar facilitating its oscillation with the shaft, said bar when oscillated to one position extending at one end across the outer face of the door, means on the end of the shaft at the opposite side of the wall from the bar for effecting the oscillation of the shaft, and means resiliently urging movement of the bar on the shaft toward the wall.
