LATCH.

Specification of Letters Patent.

PatentedAug.31, 1915.

Application filed February 12, 1913. Serial No. 747,958.

To all whom it may concern Be it known that I, FRANK KAMM, a citizen of the United States, and a resident of Lookeba, in the county of Caddo and State of Oklahoma, have invented certain new and useful Improvements in Latches, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new an useful improvements in latches employed in connection with barn doors and gates and the object of my invention is to provide a spring latch of this general character of a simple and inexpensive nature and of a compact and durable construction arranged to hold the door in closed position, and further serving as a catch to hold the door in a secure, open position, the construction being such that the latch can be as easily opened from without as within.

With these and other objects in view, the present invention consists in the combination and arrangement of parts hereinafter more fully, described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims, without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views: Figure 1, is a front view showing a fragmentary portion of a barn door secured by means of a latch embodying my invention. Fig. 2, is a trans verse, sectional view through Fig. 1, with the locking pin removed. Fig. 3, shows an enlarged, side elevational view disclosing the door as locked and held in closed position. Fig. 4, shows the latch arranged to hold the door in open position. I

In the accompanying drawings the numeral 1, designates a fragmentary portion of a barn door, and 2, a front fragmentary portion of a barn the door being secured by means of a hinge 3. 1

At a suitable pointthe door 1, is provided with what I'term a pivot staple 15.; This staple pivotally supports the latch plate 17, at one end which has a slot intermediate of its ends arranged for coaction with the looking staple 16, positioned adjacent to and in horizontal alinement with the pivot staple, as shown in Figs. 1 and 2. When this plate is held upon the locking staple 16, the same 1S 1n a horizontal position.

At a suitable. point near the outer or swinging edge I provide the door 1, as shown in Fig. 3, with a vertically extending slot 6, while secured to the outer face of the door is the slotted face plate 4, which has a slot registering with the door slot 6, as shown in Fig. 3. This plate 4, serves as a stop limiting the upward movement of the outer or main hook plate employed in my invention. This main hook plate 5 has a seat or opening 50 within its upper edge and is pivotally held upon the pin 7, secured to the ear 10, this ear being secured to the inner face of the door, as shown in Fig. 2'. This outer hook plate 5, has the rear extension 8.

Pivotally held upon the pin 7, adjacent to the outer hook plate 5, is the auxiliary or inner hook plate 11, having the seat or opening 1; within its lower edge, this construction being shown-in Figs. 3 and 4. This inner hook plate 11, is further provided with an outstanding stop shoulder 9, arranged to contact with the under edge of the outer hook plate 5, in the manner shown in Figs. 2, 3 and 4.

Secured to the door below the inner hook plate 11, is the spring 12, which has its upper end secured to the inner hook plate 11, below the extension 8. This inner hook plate 11, can be freely carried upward upon the pin 7 the'upward movement of the mem her being stopped by the end of the spring 12, contacting with the extension 8. The

spring-12, normally forces the shoulder 9, against the outer hook plate 5, as well as normally forces the outer hook plate against the upper edge of the slot 6, within the stop plate 4, as shown'in Fig. 3.

Secured to a suitable part of the door frame 3, as shown in-Fig. 2, is the ear plate 14, having the securing base 13. This plate 14, is'engaged by the in'ner'hook plate 11, this ear plate being-so arranged that the same will slide into the opening '0 within the under edge of this member 11, in the manner shown in Fig. 3. WVhen thus arranged the door' is held in secure, latched position. To open the same from without the operator simply depresses the member 5; while opening the door from within the operator raises the member 11, so that the inner hook plate will escape over the ear plate 14. Should it be desired to lock the latch While the door is closed the operator would simply carry the slotted latch plate 17 in a horizontal position, so that the same will engage the locking staple 16, and then introduce the pin 20, into the locking staple 16, or secure the plate 17, to the staple 16, by means of a padlock. In Fig. 1, the plate is shown as locked by means of the pin 20. While the door is thus locked from without the same can be easily opened from within by simply raising the inner hook plate 11.

Secured to the building at asuitable point in the path of the opening w within the outer hook plate 5, is the angular ear plate 18, having the securing plate 19. Should it be desired to hold the gate or door in an open position it is simply necessary to open the door its full extent so that the opening 00 will be engaged by the under edge of the ear plate 18, as shown in Fig. 4.

A latch constructedaccording to my invention is simple and inexpensive in construction, and both durable and efficient in operation, the latch can be opened from within or without with ease, accuracy and despatch.

Having thus described my said invention what I claim as new and desire to secure by United States Letters Patent is:

1, The combination with a door having a vertically extending slot near one edge, of a pivot staple secured to said door adjacent to and below said slot, a latch plate having a slot intermediate of its ends pivotally supported at one end by said staple, a locking staple positioned in horizontal alinement with said pivot staple arranged for co-action with said plate slot whereby said plate may be secured in a horizontal position, an ear secured to the rear face of said door adjacent to its slot, a pin secured to said ear, a main hook plate having a seat within its upper edge pivotally secured to said pin and arranged to contact with said latch plate in horizontal position, an auxiliary hook plate pivotally secured to said pin havinga seat within its lower edge and provided with a stop shoulder arranged to contact with said main hook plate to hold said hook plates in alinement, and a spring secured to said auxiliarv hook plate and to said door, said door slot limiting the upward movement of said main hook plate.
