JAMES L. COX, OF SCOTTSVILLE, NEWV YORK.
LATOH-FASTENER.
Specification of Letters Patent.
.ratentecl April 2, 1907.
Application filed February 10, 1906. Serial No. 303,517.
To all whom it may concern.-
Be it known that 1, JAMES L. COX, a citizen of the United States, residing at Scottsville, in the county of Monroe and State of New York, have invented new and useful Improvements in Latch-Fasteners, of which the following is a specification.
The invention relates to an improvement in latch-fasteners designed, primarily, for use with double doors, such as cupboard-doors or the like.
The main object of the present invention is the provision of a fastener which will automatically lock itself on the inside of the door in the closing of a door and which may be readily disconnected from the outside to permit opening of the doors by either a turning or tilting of the latch-knob.
The invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which- Figure 1 is a sectional view with the latch shown in elevation, illustrating the application of the invention. Fig. 2 is a similar view of the latch proper, taken at right angles to Fig. 1. Fig. 3 is a transverse section through the latch-casing. Fig. 4 is an elevation of the latch and casing viewed from the inner end. Fig. 5 is a perspective view of the latch removed.
The inventionis designed, primarily, for use with double doors, such as cupboard-doors, wherein one member is carried by one door and the other member by the second door, the invention being designed to dispense with the usual fixed strip between the doors and with the independent fastening for the second door.
Referring to the drawings, my improved latch-fastener comprises a casing 1, of cylindrical form, designed to be snugly fitted in a recess 2, formed in one of the doors 3, the outer end of the casing being closed by a plate 4 of greater diameter than the end of the casing, whereby to provide a laterallyprojecting flange designed to contact with the outer surface of the door and permit the use of a suitable fastening, as 5. The inner end of the casing terminates flush with the inner surface of the door and is closed by a plate 6.
The latch proper comprises a stem 7, formed at one end with an offset or lookinglug 8, preferably of the usual inclined construction, and near the opposite end with a relatively fixed washer or head 9.
In use the latch proper rests centrally within the casing 1, the head 9 resting in contact with the face-plate 4 of the casing and the stem 7 projecting beyond the face and end plates 4 and 6, the former being provided with an opening 10 to permit passage therethrough of the stem projecting forward of the head, while the latter is provided with an opening 11 to permit passage of the stem beyond the end plate, said opening being elongated, as shown in Fig. 4, to permit an inde pendent lateral movement of the stem relative to the casing. The portion of the stem projecting beyond the faceplate of the casing is provided with a suitable knob 12, by which the latch may be operated. As thus described it is obvious that the latch-rod 8 may be revolved within the casing or may be moved laterally relative to the casing, and to provide means for returning the latch to normal position after either of these operations I provide a spring 13, designed 'to cooperate with a rod 14, passed transversely through the rod 7 and projecting therebeyond. The spring member is preferably constructed of a single length of spring-wire formed to provide an arm 15, which projects forward and is turned over the latch-rod adjacent the head 9, as at 16, being then passed around and beneath the adjacent projecting portion of the rod 14, as at 17, then over above the latch-rod 7 in rear of the rod 14, as at 18, then beneath and around the opposite projecting end of the rod 14 and up over the latch-rod 7 forward of the projecting rod 14, as at 19, being projected from the terminal of this bend to provide an arm 20 similar to the arm 15. As shown, the coils 16 and 19 of the spring are enlarged to provide the necessary tension at this point, while the remaining coils snugly embrace the respective parts.
The bottom of the casing 1 is formed with a longitudinally-arranged lug 21 to provide an abutment to receive on each side the free terminals of the arms 15 and 20, whereby to prevent independent movement of said arms.
The fixture or other door 22 is designed to receive a keeper-plate 23, terminally provided with a projection 24 to receive the forward or thickened end of the locking-lug 8.
In use the door 3 may be locked by causing the same to move into proper position relative to the fixture or door 22, the inclined face of the lug 8 riding theprojection 24 of the keeper until the forward edge of said lug rides in rear of said projection. To disengage the latch, the rod 7 may be partially revolved or moved laterally relative to the casing, as may be desired, either movement being against the tension of the spring 13.
By preference the head 9 is convex on its forward edge, as at 25, to provide for the convenient lateral movement of the rod 7 in this operation of the latch.
The structure is simple and provides for an automatic engagement of the latch and a manual disengagement by either of two movements.
Having. thus described theinvention, what is claimed as new is l. A latch comprising a latchrod, a casing for supporting the rod, said rod being mounted for revoluble movement and independent swinging movement relative to the casing, and. a spring for returning the latch-rod to normal position after operation.
2. A latch com rising a casing, a latch-rod mounted W1th1n t e casing for revolutlon and for independent swinging movement, one end of the rod projecting beyond the casing and being provided with a locking-lug, and a spring fixed within the casing and adapted to be put under tension during either movement of the rod.
3. The combination of duplicate cupboarddoors, of a keeper carried by the inner side of one door, and a latch adapted on closing the door to automatically engage said keeper on the inner sideof thedoors, and means operative from without the doors for disengaging said latch and keeper, said means operating by a revolutionor tilting of the latch-body.
In testimony whereof I. affiX my signature in presence of two Witnesses.
JAMES L. COX.
