IMPROVEMENT IN PADLOCKS.
Specication forming part of Letters Patent No. 185,222, dated December 12, 1876; application led February 19, 1876. i
To all whom it may concern: Be it known that 1, JAMES W. ELLIOTT, of Beaver Falls,in the county of Beaver and State of Pennsylvania, have invented a new and use.
ful Improvement in Padlocks and Keys and I do hereby declare that the followin g is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure 1 is a view of the internal mechanism, the bolt and double lateral spring being removed,also showing detached views of the spring-tumblers and cross-bolt. Fig. 2 is a sectional view of the lock, showing an edge View ofthe double lateral spring. Fig. 3 shows the relative positions of the key and the parts of the lock when locked. Fig. 4 shows the positions of the key and parts when unlocked. Fig. 5 is a representation ot' the hasp. Fig. 6 is a bottom View of the lock-bolt, and Fig. 7 shows the form of the key.
My invention relates to an improved padlock and key and consists, tirst,`of a slotted and recessed sliding bolt, having a notched projecting pin, in combination with two notched spring-tumblers, a cross-bolt, and a double lateral spring, one portion of which is notched in its free end, and provided with a det-aining-lange; secondly, in a key consisting of a barrel provided with a series of wards and two L-shaped slots, in combination with a rod having two wards projecting therefrom, at an angle of ninety degrees to each other, through said L-shaped slots; and it further consists in the combination and arrangement of the parts which will be hereinafter more fully described and claimed.
In the description of the accompanying drawings similar let-ters of reference indicate like parts of the invention.
The bolt C is provided with openings Z d', made larger at the right than at the left hand side, recesses e e', and a notched projecting pin, g, on its under. side. This bolt ts into a groove, a, formed in the case, said groove being made longer than the bolt C to permit the latter to slide therein. The tumblers f f slide in vertical grooves formed in the case of the padlock, and are forced upward by the spiral springs h h1. The tumbler f has notches w y z, respectively, in its upper, lower, and lefthand surfaces, and has a shouldered point, which enters the recess e in the under surface of the bolt C. The tumblerf has notches x and z', respectively, in its upper and left-hand surfaces, and also has a shouldered point, which enters the recess e in the bolt C'. The cross-bolt rhas a notch, 7c, in its upper surface, which receives the tumbler j'; and said cross-bolt t' slides in a cross-groove in the case, and is operated in opposition to the tumblers ff by a spiral spring, h2. The tumbler f has still another notch, l, in its upper right-hand corner, which, when the tumbler is in the locked position, unites with a notch, m, in the partition between the tumblers f and f', and forms a recess, lm, Fig. l, which receives the detaining-ange n, depending from the arm 0 on the upper portion of the double lateral spring p q. The-upper portion ot' the double lateral spring p q has anotch, r, in its free end, andthe lower portion of said spring forms a tongue to the notch 'r, which, when acted upon by the ward s of the portion l) oi' the key from the left side, will lift both portions of the spring p g, and release the tumbler f, by withdrawing the detaining-flange n from the notch lm; but when the ward sis turned against said double spring from the right-hand side, the ward s will pass through thc notch 1^, carry the tongue or portion q to the left until it slips from the ward s, and resumes its place against the portion p. The key consists of the rod l), provided with the wards s and t, projecting therefrom at au angle of ninety degrees to each other, and the barrel D', having the wards u a1 uz a3, and the crossslots o o', connecting with parallel slots w 'w'. The key-hole is provided with recesses c c at right angles to each other'.
When the key is to be inserted into the lock the ward s, which occupies the L-shaped sloth/w, should be turned inline with the wards u,&c., which brings the ward t at right augles thereto, so that the wards s and a, &c., 'will enter the recess c, and the ward t the re cess c of the key-hole. Whenthe key has been entered into the lock the barrel D' is turned a quarter-turn to the left, which brings the ward u against the tumbler j", and forces it out of the recess e. At the same time-the cross-bolt i'. is moved out of contact with the notch z in tumbler f by means of its beveled end acting against the shoulder of notch z in the tumblerf. This quarter-turn of the barrel D carries with it the Wards s and t one quarter-turn to the left, brings the Ward s in contact with the tongue q, and the Ward t nearly in contact With the tumbler f, Which has already been freed from the cross-bolt i, as before stated. A quarter-turn, now, to the left of the rod D will cause the Ward s to remove the detaining-lange n from the notch l m, and drive the tumbler f back, thereby withdrawing the point from the recess e in the bolt G. The position of the key at this time causes the Ward s to enter the notch in the lower end of the projecting ping, and, by then drawing upon the portion D of the key, the Ward s will draw the bolt G to the position shown in Fig. 4, which brings thelargest sides of the openings d d in line With the openings E E in the lock-case, provided for the insertion and Withdrawal of the hasp B. It' the hasp B should be out of the lock it may be now inserted, and the notches G G broughtin position to receive the smaller sides of the openings d d', When, by pushing upon the rod D, the Ward s, Which is still engaged with the projecting pin g, will slide the bolt C to the position shown in Fig. 3; and by turning the key one half-revolution to the right, the Ward s will pass through the notch 1', strike the spring q, and carry it to the left until it slips from the Ward s to its place, at Which time the tumblers f f will have entered the recesses e e', and the wards of the key will be in position to permit its Withdrawal from the lock. When the lock is closed the cross-bolt i occupies the notches zz in the tumblers` ff', as shown in Fig. 3. When the lock is opened the cross-bolt i is in the position shown in Fig. 4. When locked it will be understood that the notches G G', near the ends of the arms of the hasp B, occupy the smaller portions of the openings d d', and the hasp cannot, therefore, be Withdrawn.
Having thus described my improvements, what I claim as new and useful, and desire to secure by Letters Patent, is-
1. The bolt C, provided with the openings d d', recesses e e', and notched pin g, in combination with the spring-tumblers f and j", the crossbolt fi, and the double lateral spring p q, provided With the notch 1' and detaining-iiange n, constructed and operating substantially as hereinbet'ore set forth.
2. The padlock-key consisting of the rod D,
provided with the wards s and t, in combination with the barrel D', having the wards u u1 u2 a3, and the L-shaped slots v w and t w', constructed and operating substantially as and for thepurposes hereinbefore set forth.
3. The bolt C, provided with the openings d d', recesses e e', and notched pin g, in combination with the spring-tumblers j' f and cross-bolt fi, substantially as and for the purposes set forth.
4. The hasp B, having the notches G G', in combination with the bolt C, provided with openings d d', recesses e e', and notched pin g, and spring-tumblers f f', having the crossbolt i, substantially as and for the purposes set forth.
