SPECIFICATION forming part of Letters Patent No. 241,279, dated May 10, 1881.
I Application filed April 12, 1880. (Model.)
T 0 all fav/om fit may vconce/rn Be it known that I, GO'ruLIEB M. BARTH, a citizen ot'the United States, residingin Philadelphia, Pennsylvania, have invented an lmprovement in Pad locks, of which the following is a specification.
My invention relates to an improvement in that class of locks in which a number of sets of independent lock-bolt mechanisms are arranged within a single case, my object being to so construct the lock that while difficult to pick it can be readily opened bymeans of a proper key, and can be lockedeither by the use of the key or when the key is removed. This object I attain in the manner too fully described hereinafter to need preliminary explanation, reference being had to the accompanying drawings, in which- Figure 1 is a vertical section of my improved padlock, showing the hasp locked; Fig. 2, a vertical section, showing the hasp unlocked, and Figs. 3 to S detached views of parts of the lock.
A is the outer casing otl the lock, and B the cover-plate, the interior of said easing A being adapted for the reception of a number of small casings, D, which are retained in proper position in the casing A by lugs on the coverplate. Each casing has semicircular recesses a at the ends, for the reception of the legs b b ofthe hasp E, and each casing carries a bolt, d, and tumbler e, the tumbler beingl pivoted to the bolt at the rear end, and both tumbler and bolt being properly guided and retained in the casing. -In the presentinstance the lock has three casings, D, the bolts of the two upper casings being left-handed and engaging with notches in the leg b of the hasp, while the bolt of the lower casing is right-handed and engages with a notch in the leg b of the hasp. Each tumbler is acted upon by asprin gpin, the tendency ot' which is to force the tumbler outward, and the outer end, s, ot' each tumy bler projects'through an opening in the end of its casing D, the end of the tumbler occupying a position adjacent to the end ofthe bolt d, but projecting slightly beyond the same.
On the back ot' each tumbler is a lug, i, which is adapted to and can move in a recess, m, iu the back of the casing D, containing the tumbler, not-ches a being formed at each end of the recess mi'or the. reception andretention ot' the lugi when the .tumbler is ineither ot' its eX- vtreme positions-Abat is to say, when the bolt is adrancedor retracted.
The, leg b! ot' the hasp. is confined to the casin g of the lock by. a screw=pin, h, adapted to a slot in the hasp, andsaid leghas ajoint,j, in order. that the upper portion of the hasp. may be swung back in order to more readily free the staple. The lower endotleaeh leg of the hasp is beveled on theinside, as. shown atf, in order to. eect the automatic retraction of thebolts el when the haspis thrust into the casing ot' the lock but inorder that this retraction may be effected the .lugs z' ofthe tumblers must rst he released from the4 outer notches, n, of the casings D; hence I provide eaclrleg ot' the Ahasp. with a side incline, w, for acting on the projecting ends sot thetumblers e as the hasp isthrustinto.thelock. Each leg of the hasp has alsoa side incline, fr, the reverse. ot' the inclinew, the object ot' this incline .t being to operate on the ends s of the tumblers and release the lugs i of the latter from the inner notchesm, ofthe casin gs D on the removal of the hasp from the casing A. Each leg ofthe hasp also has in the side adjacent to the ends s of the tumblers a recess, y, in which said ends ot' the tumblers rest when the hasp is inserted and the bolts projected, the lugs t'v of the tumblers then resting in the outer notches of the casin gs D and preventing the retraction of the bolts except by the action ofthe key.
When the above-described lock is fastened, as shown in Fig. 1, the operation of unlocking is as follows: The key held with its wards to the right is rst inserted into the lock until the irst set ot` wards are in position for acting on the right-hand bolt and tumbler of the rst casing D, as shown by dotted lines in Fig. 1, a suitable mark on the stem of the key or an appropriate stop within the casing determining this position. The keyis then turned halfway around, so as to retract the bolt and tumbler, which are retained in the retracted posi tion by the engagement ot' the lug fi of the tumbler with the inner notch, n, of the casing. The key is now in position to be thrust completely into the lock7 so as to act on the bolts and tumblers of the two upper casings, which IOC are retracted by another half-turn of the key,
as shown in Fig. 2, and retained in the retracted position by the engagement of the lugs t' of the tumblers with the inner notches, a, ofthe casings, as in the case of the rstbolt and tumbler. The hasp is now free to be withdrawn, as is also the key, the bolt d of the rst casing of the lock being recessed, in order to per.- mit the passage through it of the wards of the key. On reinserting the hasp the tumblers will be released from the control of the inner notches, n, of the casings D by the action on the ends s ofthe said tumblers of the side i11- clines, 10,011 the legs b bof the hasp, the bolts d consequently engaging with the notches of the hasp. When the hasp isinserted the ends s of the tumblers rest in the recesses y of the legs b b ot' the hasp, the lugs i of the tumblers engaging with the outer notches, n, of the casings D and preventing the retraction of the bolts. \Vhen, after unlocking the bolts with the key, the latter is withdrawn before the hasp, the side inclines, fr, of the said hasp, as the latter is withdrawn, release the tumblers and permit the bolts to spring ont, and on insertin g the hasp when the bolts are extended, the side inclines, w, rst operate the tumblers, and the inclinesfotl the hasp then thrust back the bolts until the latter come into line with their proper notches, into which they spring and retain.the hasp.
The incline of the leg b of the hasp is so formed as to prevent such an inward movement ofthe end s of the tumbler of the upper casing as would cause the locking of said tumbler on the springing of the upper bolt in to the end notch of said leg b of the hasp.
A greater number of casings D, with their bolts and tumblers, may be employed than are shown in the drawings, and the casings may be arranged in a manner different from that described.
I claim as my invention- 1. rlhe combination of the casing A, the notched hasp E, and a series of independent sets of bolt mechanism, each set comprising a lockin g-bol t, and a retai nin g-tnmbler operated by the hasp, some of the sets being righthanded and others left-handed, as set forth.
2. The combination of the casing A, the notched hasp E, spring-bolts d, and tnmblers e, for retaining said spring-bolts in their extreme positions, said tumblers having projecting ends adapted for being acted upon by the legs of thelhasp, as set forth.
3. lhe combination of a casing, D, having a recess, m, with notches u fn, the bolt d, a spring for acting thereon, and a tumbler, e, hung at one end to the bolt, and having at the opposite end a lug, i, adapted to the recess m, and notches a n, said tumbler being adapted to be acted upon by the key and by the hasp, as set forth.
4. The combination ofthe casing A, the casings D, having bolts d and tumblers e, and the notched hasp E, having legs, with inclines w and and recesses y, as set forth.
In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.
GOTTLIEB M. BARTH.
