BOLT.

SPECIFICATIN forming part of Reissued Letters Patent No. 11,606, dated June 8, 189'?.

` Original No. 520,227, dated May 22, 1894. Application for reissue led Tune 12, 1896. Serial No. 595,370.

To @ZZ whom it may concern:

Be it known that I, AUSTIN ADAMS, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented a certain new and useful Fas- Lening Device, of which the following is a speciiication.

My invention relates to self-locking appliances, and in particular to a fastening device primarily adapted for doors, swinging windows, or like articles; and it has for its object the provision oi' an appliance simple and inexpensive in construction, readily applied and operated, and eiiicient in practical use.

To attain the desired end, my invention consists in the construction and arrangement of parts first described, and then pointed out in the claims.

In the drawings which form a part of this specification, Figures 1 and 3 represent front elevations of my fastener; Fig. 2, a rear view of the same. Figs. 4: and 5 are edge views of my keepers, and Figs. 6, 7, and 8 are detail views of my weighted lever.

Like lettersof reference indicate like parts in all the views.

While, as before stated, my invention `is applicable to a great variety of articles, I will first consider it as applied to socket-bolts for doors, duc.

Referring again to the drawings, A represen ts a barrel ordinarily equipped with lateral iianges or base-wings A', pierced or formed with openings a for screws or like securing devices, whereby the barrel A may be secured to its seat upon any article that may be required to be fastened thereby.

lVithin the barrel A slides the reciprocating bolt-bar B, which is provided with a suitable manual operating device, as the stud b, ordinarily terminating in a knob, which stud b works in a longitudinal slot a, formed in the barrel A. I also prefer to use with my boltbar B a retractile device, as the spiral spring C, located on saidbolt-bar and lying between the stud h and the partition a2 of the barrel A, the resilience of the said spring C serving to normally hold the bolt-barB in an open or unlocked relation. The bolt-bar B is provided with an annular groove, milled or otherwise formed in the same near the extremity thereof, in which works a collar formed by closing together to a meeting-point the bifurcated extremity haof the lever B5, at t e other free end of which lever is located the ball b4. The end of my boltebarrel A is provided With an incline or angular recess A3, lwhich receives the weighted lever B3, the said lever following the incline A3 kdown to its seat when the bolt-bar Bis in an unlocked or normal open position. By means of this coustruction the weighted lever on the end ot' my bolt-bar is held flush with the edge of the door, dre., and thereby prevents the same from becoming caught or entangled in the garments of a person passing by, and I am also able-to shoot the bolt a m uch farther distance than would be the case if the bolt were set back on the door, .&c., to obviate the trouble caused by the said projecting lever B3.

Iordinaril y use in connection witlifthe boltbar B a staple or strap, as D, located adjacent to the barrel A and provided with a base-plate D and screw-holes d2, and constructed and arranged to engage the outer end of the bolt-bar B upon the same being closed or locked. This keeper D is provided with 4a hollow or open interior portion and'is preferably constructed in tubular form. The exterior face of my keeper is provided with an inclined edge ordinarily formed by cutting a spiral groove d3 in the said face, which said groove terminatesin a holding recess or cavity d4. ,The said keeper may be constructed in the form of a strap, as shown in Fig. 5, or may be provided with a bottom plate extending entirely under the same, as shown in Fig. 4.

In operation, in order to close or lock the parts, the bolt-bar B is pushed forward by means of the linger-stud b, whereupon the lever I3:s on end of the bolt-bar will follow the incline of the spiral groove d3 and entertl'ie recess d4 at the extremity of the same, the said recess extendiu g backward as regards the inotion ofthe bolt described, and the resilience of the spring C serving to draw the lever into the said cavity and thus hold the bolt-bar B in a locked relation. To unfasten or release the said bolt-bar, it is only necessary to turn back the weighted lever until it enters the groove d3, whereupon the retracted spring C, causes it to follow the incline of the groove, and by reason of the incline A, formed in the end of TOO ing around the two members of my fastener.

My invention is peculiarly7 adapted to seeurely bolt folding and sliding doors which cannot be secured by means of the ordinary bolts.

It is obvious that any one skilled in the art to which my invention relates may apply my fastener to a great numberof movable arti cles other than doors or box-lids that require to be secured in a closed relation.

vAs it is evident that many changes in the constructionA and relative arrangement of parts may be resorted to without departing from the spirit and scope of my invention, I would have'it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that I reserve the right to make such changes, and that What I claim as new, and desire to secure by Letters Patent, is

l. In a fastening device, the' combination, with a bolt-barrel provided at its extremity with an inclined recess, of a spring, anda spring-reacted bolt-bar working therein, and provided lat its extremitywith a weighted 1ever constructed and arranged to travel along the edge of the extremity of said incline when retracted by the spring,thereby automatically `iiushing itself with the said bolt-barrel.

2. In a fastening device, the combination, with a bolt-barrel and with a spring-reacted bolt-bar working therein, and provided at its extremity with a weighted lever, of a keeper consisting of a plate provided Witha hollowr interior portion provided with an inclined edge formed by cutting a spiral groove in the face of the same.

3. In a fastening device, the combination, with a bolt-barrel and with a spring-reacted bolt-bar working therein, and provided at its extremity with a weighted lever, of a keeper consisting of a plate provided with a hollow interior portion and with an inclined edge formed by cutting a spiral groove inthe face of the same, and with a holding-recess located adjacent to the said groove.

4. In a fastening device, the combination, with a spring bolt-bar consisting of one integral piece and provided with an annular groove formed therein near the end of the same, of a weighted levermovably mounted thereon and provided with a bifurcated eX- tremity constructed and arranged to be closed to a meeting-point within the said groove, whereby the solid head thus formed receives the force or blow of the spring-reacted bolt.

5. In a fastening device, the combination, with one member constituting a keeper for. the latch provided with a spiral bearing or slot cut through the exterior Wall thereofand terminating in a locking-recess, of another member constituting a latching device and consisting of a-rotatable member constructed and arranged when engaged lwith the first member to follow the groove suiiiciently far to become locked therein.

6. In a fastening device, the combination, with one member consisting of a pivoted or swinging latch, of another member consisting of a keeper provided with a spiral slot or way cut through the Wall thereof, the rear edges of which incline upwardly and rearwardly against which the latch works, and also provided with a locking-recess extending downwardly and rearwardly, substantially as speci` lied.

In testimony of the foregoing specification I do hereby sign the same, in the city of New York, county and State of New York, this 19th day of May, A. I). 1896.

AUSTIN ADAMS.
