TRUNK-LOCK.
Specification of Letters Patent.
Patented Mar.. 17,1914.
Application filed September 10, 1913. Serial No. 789,218.'
To all 'whom it may concern Be it known that I, SARPALA MARTIN, a subject of the Czar of Russia, residing at Marquette, in the county of Marquette and State of Michigan, have invented new and useful Improvements in Trunk-Locks, of which the following is a specification.
This invention relates to certain new and useful improvements in locks, the primary object of the invention being to provide a lock which is simple ofconstruction, reliable and etiicient in action, and which can only be operated in a determined manner and by a special form of key.
A further object of the invention is to provide a double swinging bolt lock of the character described, in `which springs are provided for holding the bolts normally projected and locking them against releasing movement, combined with tumblers for retracting the springs to permit the bolts to be actuated.
The invention consists ofthe features of construction, combination and arrangement of parts hereinafterV fully described and claimed, reference beinghad to the accompanying drawings, in which Figure 1 is a perspective view of a lock constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section through the lock taken on aline between the locking bolts and keyhole plate. Fig'. 3 is a similar view taken on a line between the back plate of the lock casing and the tumblers. Fig. l is a horizontal longitudinal section on the line 4.-4 of Fig. 2. Figs. 5 and 6 are vertical transverse sec tions on the line 5-5 of Fig. 2 looking in opposite directions. Fig. 7 is a perspective view of a form of key which may be used in connection with the lock, showing the movable bit retracted. Fig. 8 is a longitudinal section through the key showing in itull and dotted lines the movable bit retracted and projected.
In carrying my invention into practice I provide a lock casing including a back plate 1 and a keyhole plate 2, said casing being provided with a pair of spaced openings 3 for the entrance and exit of the keepers, which may be oi any suitable construction. The plate 2 is provided with a keyhole l of ordinary form, and the plate 1 with a keyhole 5 to receive the outer end of the stem of the key when fully inserted. Extending between the said plates land 2 are spaced pins 6 and 7, which are arranged in horizontal alinement with each other and above the plane of the said keyhole A and opening 5. Supported by these pins 6 and 7 is an intermediate key guiding or partition plate 8 having a keyhole 9 corresponding to and arranged Vin alinement with the keyhole 4.
Pivotally supported by the pins 6 and 7 are locking bolts l0 and 11, which bolts are verticallydisposed and pivoted at an intermediate point between their ends to swing toward each other for a releasing action and away from each other for a locking action. The upper ends of the bolts are provided with outwardly projecting locking hooks 12 for engagement with the keepers, and said bolts are respectively provided below the pivot pins 6 and 7 with beveled. and straight surfaces 13 and 1A adapted to be engaged by the bits of a double-bitted key to spread the lower ends of the bolts and thus move their hook ends 12 inwardly to a releasing position. The bolts are provided at the lower ends of their outer edges with stop lugs or projections 14C which are arranged in the path of the laterally bent ends 15 of locking and releasing springs 16, said springs being secured at their upper or opposite ends by screws or other similar fastenings 17 to the casing. The springslG, are 'movable toward and from the sideedges of the partition plate in a direction longitudinally of the casing, and their ends 15 are arranged in the path of outward movement of the shoulders 14 of `the locking bolts. As the lower en dsof the `locking bolts are movable on aros at an angle to the line of yielding motion of the springs, it is apparent that the springs normally lock the lower ends of the bolts against outward movement, thus maintaining the hooked ends of the bolts normally in locking position. After actuation ofthe lock and removal of the key, the springs also serve to return the bolts to normal llocking position, thus rendering them self-acting in this connection.
Pivotally mounted upon the pins 6 and 7 between the partition plate 8 and back plate l of the casing are tumblers 1S and 19 for coaotion with the respective bolts 10 and 11. The bolts and tumblers are loosely mounted on the pins 6 and 7 and the tumblers are movable in planes parallel with the path of movement of the bolts. The tumbler 18 is provided with a beveled surface 20 and the `tumbler 19 with a straight or slightly curved surface 21 for coaction with sections of the bits of a double-bitted key, whereby said tumblers may be swung outwardly. The outer edges of the tumblers are disposed in line with and normally engaged by the ends 15 of the springs 16, whereby the tumblers are normally maintained with the bolts in retracted position and are so arranged that upon the outward swinging movements of the lower ends of the tumblers, the springs will be forced outwardly beyond the paths of the shoulders 14, thus permitting the lock-ing bolts to be moved to unlocking or releasing position. The upper ends of the tumblers are provided at their inner edges with stop shoulders or projections 22 normally engaged by shoulders 23 on the bolts, whereby the tumblers normally coperate with the springsto hold the bolts from releasing movement. The shoulders 23 are adapted to engage stop shoulders 24 formed on the upper edge of Y the partition plate 8, whereby the outward swinging movement of the hooked ends of the bolts is limited.
It will be understood from the foregoing description that in order to retract the locking bolts it is necessary to employ a key having diametrically disposed bits bifurcated to provide engaging projections for action on opposite sides of the partition plate 8 to simultaneously engage the bit engaging surfaces of the two sets of bolts and tumblers. In Figs. 7 and 8 I have shown a form of key 25 which may be employed. This key has a round shank or stem 26 of a size to fit the round portions of the slots 4 and 9 and the opening 5 and provided with oppositely disposed bifurcated bits 27 and 28. The bit 27 is fixed or rigid with lthe stem, while the bit 28 is adapted to normally lie within a recess 29, so as to allow the key to be inserted through the slots 4 and 9, and to be projected outwardly when the key is so inserted, so that the divided portions of the respective bits will be disposed on opposite sides of the plate 8 in position to engage the bit engaging surfaces of the bolts and tumblers, so that upon turning the key to the left the lower ends of the tumblers and bolts will be forced outwardly.V By this means the springs 16will be moved out of the paths of the stop' shoulders at the llower ends ofthe bolts, thus permitting the hooked upper ends of the bolts to be 'swung inwardly to releasing position. VVhen the key is turned back to normal position and removed, the pressure of the springs upon the tumblers and bolts will automatically return thesame to ynormal or locking position.
For the purpose of projecting and retracting the bit 28, said bit is mounted upon the outer or free end of an arm 30 pivoted adjacent its inner end upon a pin 31, said arm being arranged in a normally inclinedl position for movement within a slot 32 communicating with the recess 29. The arm is adapted` to be engaged by a controlling member 33 connected with a finger piece 34 movable in a guide slot 35 in the finger piece of the key, said member 33 being adapted to vslide in contact with the shank to positions on opposite sides of the line of the pivot 31 whereby the shank may be tilted to project or retract the bit 28 as Vwill Vbe readily understood. Hence it will be seen that the key must be inserted with the bit 28 retracted in order to pass through the keyholes 4 and 9, and that the bit 28 must then be projected in order to provide the required number of engaging surfaces for coaction with the tumblers andbolts. TvVhile, ofcourse, the keyaway from the bolt and at an angle to its swinging movement for releasing said bolt.
2. A lock including a pivoted bolt having a locking shoulder at one end and a keeper engaging member at its opposite end, a releasing tumbler movable in the same direction as the bolt, and a spring adapted to engage and retain the bolt and tumbler in normal position and lying in the path of said locking shoulderto normally lock the bolt from movement, said spring being adapted to be released and moved out :of the path of movement of the bolt bythe action of the tumbler.
3. A lock including a casing having a keyhole therein, a partition plate arranged within and spaced from the walls of :the casing and having a keyhole registering with the keyhole therein, locking bolts -pivotally mounted upon one side of said parti- Y tion plate and on opposite sides of the keyhole therein, releasing' tumblers mounted upon the opposite side of the keyhole plate in line with the respective'tumblers, said bolts and tumblers being adapted to be engl'aged and simultaneously operated by a c ouble-bitted key, and springs for normally locking the bolts from releasing movement and adapted to be moved out of the paths of the bolts by the action of the tumblers.
4. A lock including a casing having a keyhole therein, a partition platedisposed within the casing between thewalls thereof and provided with a similar keyhole, pivoted locking bolts upon one side of said plate,
said bolts having keeper engaging members at one end and looking shoulders at their opposite ends, tumblers pivotally mounted upon the opposite side of the keeper plate in line With the bolts and movable in paths parallel with the bolts, coasting surfaces upon the tumblers and key engaging ends of the bolts `to hold sueh ends of the bolts from releasing movement, and springs arranged to engage and hold the tumblers and bolts normally retracted, said springs beingl arranged to lie in the paths of movement of the looking shoulders of the bolts to look said bolts from movement and to be moved out of the paths of movement of said looking l5 shoulders by the action of the tumblers.
In testimony whereof I aix my signature in presence of two Witnesses.
