FRANK F. LANDIS, OF LANCASTER, PENNSYLVANIA.
Letters Patent No. 77,740, dated ilfay '12, 1868; mttedateol May 7, 1868.
IMPROVEMENTIN PADLOGKS.
"Flu Stlgttnlc I'tltl't'tl! to llt flg'rst "girders Easter: mrt limiting pint at the S'dlltt.
TO ALL WHOM IT MAY CONCERN:
Be it known that I, FRANK F.'LANDIS, of Lancaster, in the county of Lancaster, and .State of Pennsyl- I Vania, have invented a new and useful Improvement on Locks; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the.
annexed drawings,-inaking a part of this specification, in which- Figure 1 is a plan view of a modification of my lock, patented March 5, 1867, No. 62,545, adapted. to a padlock, the pin or pins on the key (in this case a socket-key) employing the-twin bolts B, one on top of the other, with the feet 0 resting against the perforated guard-chamber I-I, all of which I consider substantially met in my patent aforesaid. I
Figure 2 is an improvement up the former and the subject of this application.
Figures'fa, I, II, III, IV, 820., portions of my lock shown separately.
The nature of my invention consists in providing a padlock, that, hile it shuts with a spring, and can beopened in an instant by any one acquainted with the modztsoperandt, it is yet so contrived that a person with the key may work an hour in turning to the right and left, and fail to open it without complying withthe simple conditions required. At the same time, the lock is strong, and no amount of pounding will spring the bolt, nor: can it be picked, nor an impression taken formaking a key, and is found in every respect satisfactory to secure I doors, Xtc.
To enable others skilled in the art to make and use my invention, I will proceed to-describe its construction and operation.
-in like manner, both being separately cast, in the ordinary manner, of brass or other metal.
Fig. 2 presents the plan of the interior.
Fig. 3. I'shows a perspective view of the hox'or case, with its lugs L M, pivots O N, and connecting-pins 1, 2, 3, and'4, for the top or cover II, with the hey-hole K, and spring-covers, and holes for the pins, numbered The l-ink holt A, with its notch, a, (VII,) sets on its pivot N, and, with its rounded, conic, notched end, en'tersthe opening y of the top frame Y, and presses the bolt B back on its spring-tumbler G D, which springs forward, and looks into the notch a of the link A, and secures it in' that position.
The parts introduced for unlocking consist in setting the cylinder J, III, over the fixed pin 0, to which pin the socket in the key is adapted, which enters through the outer cover, II, into the cylinder, revolving freely with the key around the pin as an axis, through K, in J, the top of theicylinder or barrel, III. The bottom of this cylinder, with its perforated guard-chamber H I, and pillars and guide-posts, is cast as shown in Figs.
IV and V.
Fig. 1V showsfalse holes, of any number, partly drilled in, to preventtaking a-cast, so as to know to which perforation the pin on.the key is adapted, since each key can be varied in the position of the pin. I v t Fig. V shows the side of the vertical'guard -chamber, with a single perforation through the .thick wall H.
Against this side the winged tumbler E rests, with its wing or raised flat side covering the wall H, and held u by a. spring against it. I This tumbler has a rounded perforated angle, f, with a'hole for slipping over the pivot f in the cylinder, the other arm extending inwards nearly at a right angle, where it has a vertical ,pin, e,-
to which a bolt, Gr, is hinged by its socket g, Flg., VI. This hinged piece G is-held between the two guide-lugs W W of the cylinder, and, when in position, held by the spring. The point G projects beyond the cylinder, and
enters between the lugs M M in the casing, These lugs are rounded on their inner face, from the centre out= wards, forming inclined planes, against which the jointed piece .G is pressed back, but spring forward into the open space between saidlugs as-the cylinder is turned, by the aid of the key, in either direction. This hinged piece G is in like manner pressed back when the cylinder is revolved,-so as to bring it in contact with the upper or rounded nose or projection D on the dog or tumbler (l, (VIII) In moving from left'to right, having slipped over the same,-it'again springs out, and will allow the cylinder to revolve round again to catch between the lugs M M, and thus it may be turned again and again.
The operation of the cylinder is so, that when the key is inserted, and turned to the right, (or in the only direction it can he"turned,)* quarter round, it comes in contact with the thickened wall H of the chamber. The pin on the key now strikes a headed pin loosely in the perforation made through the wall, (or two such pins', if desirable.) The flattened head of the loose pin being against the wing F on the tumbler E, (YL) it is forced outwards, drawing theother hinged'pieee G in, and disengaging it from between the lugs M, said' tumbler acting 'on its pivot f. Thekey, in this position, revolves the cylinder round, past the hook D on the lever C, (VIIL) When relaxed, the jointed piece springs out, and on reversing the motion from right to left, it catches against the fiat side of the lever D op tumbler Q, moving on its pivot P, and pushes the lower end upwards, causing the upper, end, which is connected with the spring-bolt'B by an oblong slot, over a pin, 6, so as to pushit backwards, thereby drawing the bolt Bback on its guide-lugs L, and disengaging it from the notch a in the linlcbolt A, requiring at the same instant a pull upon'the 1001:;50- as to draw the link out, otherwise, the action of the lever having allowed the catch to pass, the bolt springsvintoo its place, and locks again. It therefore demands a half turn to the'right, then quickly to the left; and a pull upon-the lock or link, to draw it out, on the instant the bolt is withdrawn, otherwise persons may fruitlessly turn round and round, unlock and as quickly lock the same, for zilength of time, andjfail to open it; but when understood, it is readily unlocked, and locked again by simply forcing the link down, without the aid of'the key, making italtogether a strong, cheap,'and reliable lock for doors of any kind, where padlocks are used, and found to render satisfaction in every particular.
I am aware that revolving cylinders are not new; thatvarious devices are employed and patented, embracing a, diversity of arrangements claimed by other inventors, when the link-bolt is locked by interior tumblers, levers, and springs. But I am not aware thatany revolving cylinder has a chamber or wall, H I, perforated, and partially perforated, with a winged tumbler, E F, operated in the manner specified and shown;
What I claim as my invention, and desire to secure by ljette'rs Patent, is
1. The rounded right angled chamber or partition Ipwith its wall,- H, thickened and perforated, in combinationwiththe hinged and winged tumbler G E F, on its pivot f, within a cylinder, J, revolving freely on the pin 0, for the socket in the key, arranged and operated in the manner specified. 1
2. In combination with said chamber or partition I H, and tumbler G E I also claim the arrangement of the lever C, with its hook D, in connection .with the spring-bolt B, by the pin 5, when actuated in the manner and for the purpose set forth.
FRANKF. LANDIS.
