CHARLES HARRISON, OF ARMSTRONG, ILLINOIS.

BARN-DOOR LATCH.

To all whom it may concern:

Be it known that I, CHARLES HARRISON, a citizen of the United States, residing at Armstrong, in the county of Vermilion, State of Illinois, have invented certain new and useful Improvements in Barn-Door Latches; and I 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 has relation to a latching device for barn or other heavy doors.

It is the object of the invention to provide a strong latch for barn-doors that will endure severe strains and hard pulls without affecting its efficiency, and that may be conveniently operated from the inside or outside to open it-the latching being automatic and that may be securely protected by a casing on the inside of the door where it is secured.

The nature of the invention is ascertainable from the device portrayed in the annexed drawings, forming a part of this specification, in view of which it will first be de-. scribed in detail with respect to its construction and mode of operation and then be particularly pointed out in the subjoined claim.

Of the said drawings-Figure 1 is an inside view showing the latch as applied to a door. Fig. 2 is an outside view of the door at the point where the latch is applied. Fig. 3 is a horizontal section taken in the plane 3-3 ofFig. 1. Fig. 4 is an inside view of the latch removed from the door. Fig. 5 is a perspective view of the striker plate and catch. Fig. 6 is a view of the bolt on the door when opened back, and the back catch about to be engaged by the hook of the outside pull to hold the door back.

Similar characters of reference designate similar parts or features, as the case may be, wherever they occur.

In the drawings, 10 designates the bevel ended latch bolt that is disposed in a casing 11 forming an open ended square channel having two oppositely disposed outwardly flared securing flanges 12 extending laterally from its inner edges, which flanges are perforated for the reception of the shanks of screws by which the casing may be secured to the inside of a barn-door. This casing is open at its forward end as shown in Fig. 5,

the rear end being closed by means of a perforated stop plate 9 having a central opening and held transversely within one end of said channel. The forward projected end is square in cross section and beveled as at 13 from the inside outwardly so that when the door is closed the said beveled projecting end may come into contact with the inclined side of the recessed striker-plate 15 and sliding thereon, be pushed back in its channel and to the opposing stationary part of the door structure. The head 10 is of a size to snugly fit into said casing as shown in Fig. 3. The bolt 10 has a square face 7 opposite its bevel end 13, and centrally projected from this. face is the straight stem 17 of the pull hook 19, the stem of which extends through the openings within the stop plate 9, the pull hook ending in a recurved portion as shown in Fig. 3. By means of this pull hook 19 the bolt 10 is secured to the housing. This housing, as shown in Fig. 4, is entirely open upon its under side, and the door to which the latch is secured forms the fourth side of the bolt channel. Held upon this stem 17 and interposed between the stop plate 9 and the end of the bolt 10 is the spring 18, which normally forces this bolt outward. From the inside the, bolt is operated by means of this pull hook 19. The bolt is operated in opening the door against the strain of the spring 18. 20 designates a laterally extending pull hook which is projected through the open bottom of said casing and is adapted to extend through a slot in the barn-door and is connected at its inner end with the rear face of the bolt 10 so that from the outside the door may be opened by pulling back on the pull-hook 20. In this way a very efficient and at the same time a simply constructed and readily operated latch is provided for a barn-door that may be operated either from the outside or from the inside. From this it will be seen that the casing 11 forms a bolt receiving channel within which the bolt is snugly held. The hook 20 is so constructed that when the door is opened back fully against the adjacent side of the barn A it may engage a catch 21 suitably secured thereon to hold the door open, and against being blown shut by the wind as indicated in Fig. 6, where the door is represented as just approaching its full-open position. It is that the pull 20 may perform this function as well as being convenient to catch hold of that it is given a, hook-like form. This construction provides a strong, simply constructed barn-door latch which can be operated from both sides.

As disclosed in Fig. 6 the outside pull hook 20 is made to serve a double purpose, in that in providing an ordinary staple and securing the same at the proper point, the barn-door may be held in an open condition, in that the hook 20 will engage the staple and so prevent any slamming of the door or accidental closing of the same during a Windstorm.

The securing flanges 12 extend the full length of the channel forming bottomless housing, and the bolt 10, it will be noted, is of a length less than said channel. The hook end of the member 19 is normally in engagement with the end of the casing 11 as shown in Fig. 4 and limits the outward movement of the bolt 10. This pull hook 19 thus performs a triple function in that it serves as a pull for the bolt, prevents the bolt from becoming detached from the housing after the latch has been assembled and finally serves as a stop in limiting the outward movement of the bolt 10.

Having thus described the invention, what is claimed as new, is z- The combination with a latch housing bent to form a top and two sides, said housing having a uniform rectangular interior cross section throughout its length, each of said sides having a perforated securing flange, a stop plate having a central opening closing one end of said housing; a rectangular latch bolt within and closing the other end of said housing, a pull hook pass ing through and completely filling said central opening and being secured to said latch bolt,.a spring held entirely Within the easing and coiled about said hook between said latch bolt and stop plate, the end of said hook being normally held in front of said top, and a laterally extending pull hook projecting from said latch bolt beyond said bottomless housing in a direction at right angles to said first mentioned pull hook, all arranged as set forth.

@111 testimony whereof, I afliX my signa ture, in presence of two witnesses.

CHARLES HARRISON.
