To all wiz/omit may concern." g y 'Be itknown that I, NOAH. M. HUTTON, a citizen of the United States, residing at Chicago, in the county of Cookv and State oflllinois, have inventedk certain new and useful Improvements in'DoorfLatches, ofwhich the following is a specification. My invention relates to fastenings for l doors, being in the naturelof an improved latch of that general type wherein a hasp secured to thedoor cooperates with a staple and padlock on the casing, or vice versa.

The object of the invention is to provide a simple, strong, and convenient device which may be operated at.eitherV side of the door and which shall be reversible for either right or left hand doors.

To this end my invention consists in a doorlatch having the peculiarities of construction and mode of manipulation substantially as y hereinafter described, and defined in the claims.

My invention in its preferred formis'illus- 1 l trated in the accompanying drawings, .where- Figure 1 is a front elevational view of the complete device in latched position, shown as applied to a door and its casing. 'Fig 2 isa top plan view of the device shown in Fig. 1 with padlock applied'and with thedoor and casing in horizontal section on substantially the median line of the device, and Fig. 3 is a view similar to Fig. 1 with the hasp in an unlatched position. f

Referring to the drawings, 5 designates the 4 vertical marginalportion of a door, and 6 thereof.

designates the stationary casing alongside Secured .to the former, as by screws 7, is a latch-plate 8, projectingfrom the face of which latter near its` oppositel ends are upwardly-extending tongues 9, designed vto n constitute seats or supports for the shank 10 of'a has which is pivotedin and centrally of the p ate 8 at one end and4 on its opposite end vcarries a triangular-shaped head 11,

adaptedl to partially enter a staple 12,' projecting from the face of a plate 13, secured to the casin 6, as by screws 14. The, headof the hasp as secured thereto and projecting from its outer face a staple 15, kwhich when the headis latched with the staple 12 overliesthe latter and may be locked thereto by an ordinary padlock 16. (Shown in Fig. 2.) The inner end of the shank 10 of the hasp is fast on a pivot-pin 1 7, which latter has fast on its outer end a wing-nut 18 and fast on its inner end another wing-nut 19, Fig. 2, which lies within a socket 20, formed in the inner face of the door.

.i With theparts in the position shown inl Fig. 1 the hasp engages the staple, andthe .doorV is latched, while with the padlock 16 applied, as shown in Fig. 2, the door is'locked. In order to open the door from its latched position, it is necessary only to give either. thumb-nut 18 or 19 a twist with the thumb and finger through a half-circle from the outv side or the inside of the door, as the case may be, which swings the hasp over to the position shown in Fig. 3. An equal turn of either thumb-nut in the' opposite `direction effects the latching of the door in an. obvious manner. The tongue 9, remote from the casing, serves lto support the hasp in idle position, and by making thel plate 8 with duplicate ends, as shown, and the hasp-head in duplicate on opposite sides of its longitudinal medial line'th device is adapted fory application for either right or left hand doors, and by making the hasp-operating means accessible on both sides of the `door the latter can be latched and unlatched with equal facility on either the outside or the inside. The triangular or wedge-shapedform of hasp-head insures a snug engagement with the staple, thus preventingrattling and affording a latch combining great strength withsmallweight. The device is applicable to either sliding or hingeddoors, andthe-described manner of operating the hasp in unlatching by swinging away from the margin of the door is of importance, since it prevents all danger of the hasp catching upon objects passing in and out of the doorway and also prevents liability ofbendingor breaking of the hasp through accidental slamming of the door.

While l have shown and described the haspv l i IIO respectively, a pivot-pin rotatably mounted l 99 the head around to a position where it lies in said latch-plate centrally thereof and provided on each end with turning means, a hasp fast at one end on said pivot-pin and having a vertically-disposed ilat triangular or spearshaped head on its other end, and a horizontally-disposed staple secured to the casing and adapted to receive and seat the lower portion of said hasp-head, substantially as described.

2. A reversible door-fastening of the character described, comprising, in combination, a latch-plate having hasp-supporting tongues projecting laterally from each end thereof, respectively, a pivot-pin rotatably mounted in said latch-plate centrally thereof and provided on each end With turning means, a hasp fast at one end on said pivot-pin, said hasp having at its other end a vertically-disposcd ilat triangular or spear-shaped head provided With a central horizontally-extending staple, and a horizontally-disposed staple secured to the casing and adapted to receive and seat the lower portion of said haspehead and be locked to said hasp-head staple, substantially as described.
