SLIDING-DOOR FASTENER.

Specification of Letters Patent.

Patented Nov. 21, 1916.

Application filed September 22, 1915. Serial No. 51,949.

To all whom it may concern.-

' Be it known that I, CALVIN A. rims HURST, a citizen of the United States, residing at Clyde, in the county of Lamar and State of Mississippi, have invented certain new and useful Improvements in Sliding- Door Fasteners, of which the following is a specification.

This invention contemplates an improved latch for sliding doors,gates, or windows, and has as its primary object to provide a device of this character which will be positive in operation and which will be automatically movable to locked position.

The invention has as a further object to provide a latch wherein the locking member employed may be locked in operative position, so that the coacting elements of the latch will beheld firmly connected or may be locked in inoperative position, so that the coacting elements of' the latch 'may slide freely relative to each other.- And a still further object of the invention is to provide an improved latch of the above described character employing a pivoted hasp which may be swung to inoperative position out o the path of the locking member.

Other and incidental objects will appear as the description proceeds and in the drawings wherein I have illustrated the preferred embodiment of the invention and wherein tion illustrating the coacting elements ofthe latch in engagement with each other,

this view also showing in dotted lines, the manner in which the hasp of the latch may be swung to inoperative position, Fig. 3 is a top plan view showing the locking member held in operative position in engagement with the hasp of the latch.

In carrying out my invention, Iv employ a supporting member including aba'se plate 10 to one side of which is fixed a substantially rectangular frame 11 arranged'to extend transversely of the base plate to project laterally therefrom. The frame 11 at its rear end, terminates in a solid block 12 to the upper face of which is pivotally connected a stop 13 having a transversely incllned forward beveled edge. Mounted to slide freely within the frame 11 is an annuframe. For convenience, I have shown the base plate 10 of the supporting member as attached to a wall conventionally illustrated at'16.

Associated with the locking member isa hasp 17, the forward end of which is convex to engage the locking member 14, while. the said hasp is longitudinally slotted as at 18 to freely receive the locking member. Pivotally supporting the hasp, is a block 19 having an upstanding car 20 formed thereon which receives a pivot pin 21 eX- tending through the inner end of the hasp. The hasp 17 adjacent its inner end is cut away upon one'sideto provide a laterally projecting shoulder 22 adaptedto engage the forward end edge of the ear 20 for, supporting the'hasp in substantially horizontal operative position,- while the block 19 in the rear of the inner end of the hasp is provided with a shoulder 23 inclined from the vertical and adapted to engagethe hasp when swung upon its pivot for supporting the hasp in inoperative position, as shown in dotted lines in Fig. 2. r

The block 19 is mounted to project laterally from the forward extremity of a base plate 24 and may be formed integrally with the said plate. For convenience, I have shown the base plate connected to a sliding door conventionally illustrated at 25, the base plate 24 being so mounted that the hasp 17, when in normal position, as shown in Fig. 1, will slide beneath the frame 11 of the supporting member to engage the looking member 14.

Normally, the locking member 14 will gravitate to engage the pin 15 and will depend therefrom below the frame 11. When the door 25 is closed, the forward convex end of the hasp 18 will be moved to engage the locking member which will then be forced upwardly within the frame to the position shown in dotted lines in'Fig. 2. In this connection, attention is directed to the fact that the forward end wall of the frame 11 is provided with an inner concave face to engage the locking member. When the door is entirely closed, the slot 18 of the hasp will assume a position to receive the locking member which will then gravitate to position depending from the pin 15 and extending through the hasp in which position of the locking member, the door will be securely locked.

It will now be noted that the stop 13 may be moved upon the frame 11 to engage the locking member 1%, as shown in Fig. so that it cannot be shifted upwardly within the frame 11 to release the hasp. Thus, the elements of the latch may be locked in coacting relation. However, in the event it is desired that the locking member ll may be held in inoperative position, it may be shitted to the position shown in Fig. l and the stop 13 engaged therewith by its torwart beveled edge, so that the stop will then hold 7 the locking member elevated and out of the path of the hasp 17. Should it for any reason be found inconvenient to thus fix the locking member. the hasp 17 may be swung upon its pivot to engage the shoulder 23 of the block 19 out of the path of the locking member, so that the door 25 may be freely opened, or closed.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. A device of the character described including a supporting member having a base, a frame extending laterally from the base and terminating at one end in a block, a locking element shiftably mounted within the f 'ame, a hasp shiftable to engage the locking element, and a stop carried by said block and movable to engage the locking element for holding it in inoperative position out of the path of the hasp or for holding it in operative position in engagement with the hasp.

A device of the character described including a base, a block projecting laterally from the base and an upwardly extending shoulder, a hasp pivotally mounted upon the block, a supporting'member, and a locking element shiftably mounted upon the supporting member, the hasp being shiftable to engage the locking element and being shiftable to a position in engagement with said shoulder out of the path of the locking element.

3. A device of the character described ineluding a supporting member, a locking element shiftably mounted thereon, a base having a block projecting laterally therefrom and provided with cut away portion, a hasp pivotally mounted in the cut away portion of said block and shittable to'cngage the locking element, and'a shoulder projecting laterally from the hasp and adapted'to engage the outer side wall of CALVIN A. WHITEHURST. [L. 8.]
