RUDOLF A. BORSKY, OF FRAGUE-ZIZKOV, AUSTRIA-HUNGARY.
PADLOCK.
Specification of Letters Patent.
Application filed June 19, 1913.
flatented Dec. 16,1 913.
Serial No. 774,714,.
To all whom 2'25 may concern Be it known that I, Ronomr A. lionsid', subject of the Emperor of Austria-Hungary, residing at Libusina S12, Prague-Zizkov, in the Kingdom of Bohemia, Austin-Hungarian Empire, have invented certain new and useful Improvements in Padlocks, of which the following is a specification.
The object of my invention is to provide a safety padlock, which completely covers the door loops on which it is fastened, .lits closely to the door and does not possess any outwardly projecting parts such as shackle, which could be removed by breaking, cutting or filing.
A further object of my invention is to increase the safety of the padlock byconstructing it so that two or more different keys must be used for unlocking the same.
In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood, that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to.
In the drawing,Figure 1 is a view of the inside of the padlock. Fig. 2 is a crosssection on the line Y--Y of Fig. 1, of the padlock. Fig. 3 is a view of the lower part of the padlock. Fig. t shows a detail of F l in a different position. Fig. 5 and Fig. (5 are views of another detail. Fig. 7 is a View of a key to the padlock.
In the drawing, 1 designates the casing of the padlock provided with a rim 2. The side-plate 3 is attached to the casing by means of rivets at. In the casing 'l. are provided openings 5 for the stems of the keys and a square opening 6 surrounded on the inner side of the casing by a rim 7. in two opposite sides of the rim a bolt 8 is slidably guided. One end of the bolt 8 is acted upon by a spring 9 which attached to a post 1-0 provided in the casing, while the other end of the bolt is slidably guided in an opening of the rim 2 and is so shaped that in the locked position it is flush with the outer surface of the rim 2. The belt 8 is provided with a feather S engaging in a groove in the rim 2. The bolt 8 is further provided with transverse apertures lladapted to receive the off-set ends 12 of bars 12, which are slidably mounted in the casing so that they can move perpendicularly to the direction of movement of the bolt 8. To this end each of the bars '12 is provided with a slot 1.2-} .in which engages a pin .1-lattached to the casing, and is further provided with a pin 15, which engages in lt-shaped slots 19 of several superposed tumblers 16; these tumblers being mounted to rock in the easing on pins 17 attached to the casing, and being acted upon by springs 18, the opposite ends of which bear against posts which are attached to the casing, so as to force the tumblers normally in the direction toward ti 2 apertin'es 5.
On the sides turned toward the apertures 5 the bars 12 are each provided with two curved portions 21 and 22, which are divided by a recess 23. lioth the curved portions 21, and 22 are delimited by sectors of a circle of the same radius described from the centers of the apertures 5, the sector of the portion 21 being coneentrical with the aperture when the bar 12 is in the unlocked end-portion, while the sector of the portion is concentrical with the aperture 5 when the bar 12 is locked.
In Fig. 1 the left-hand half of the locking device is unlocked, while the right-hand half is locked. in the i'inlocked position the pin 15 engages in the recess 15) of the slot 19 and thus limits the movement of the tumblers 16 caused by the springs 18, and at the same time secures the bar 12 in such a position in which the oil-set end 152 is free of the aperture 111. in the bolt 8.
In applying the padlock according to my invention to a door, the bolt 8 must be drawn out till it is free of the opening (3 whereupon the padlock is slipped on the two loops 2+t of a door which are to be secured, in such a manner, that the said loops penetrate into the opening (3. The loops i=1; should be of such dimensions and shape and so distanced from each other, that on the padlock being applied till its casing l. bears against the face of the door, the two loops 9fttouch each one of the sides of the rim 7 and stand out far enough into the inside of the padlock to allow the bolt 8 to pass through the openings of the loops. The bolt 8 is thereupon pressed inside the padlock against the action of the spring 9, till its outward end is flush with the surface of the rim 2, and is held, preferably by the finger of the oporator resting on its said outer end, in this position, in which the apertiu-es 1K1. lie opposite the offset ends 12. One of the keys 25 is then inserted through the slot provided in the side-plate 3, till its stem enters the respective aperture 5. ()n the key being turned the tumblers 16 are swung aside by the step-bit of the key against the action of the spring 18, till the pin 15 is released from engagement with the recess 19 of the slot 19, against which it has been bearing. In the neXt moment the lowest projection 25 of the step-bit 25, which had passed free of the portion 21, engages in the recess 23 and projects the bar 12 perpendicularly to the bolt 8, till the off-set end 12 enters the aperture 11. During this movement the bar 12 is guided by the pins 1% and 15 engaging in the slots 13 and 19, respectively (Fig. 1). In the end position in which the off-set end 12 has completely entered into the aperture 11 and the pin 15 has arrived to the end of the slot 19, the tumblers 16 are swung backward by the spring 18 till the pin 15 engages in the recess 19 of the slot 19, thereby limiting the swinging movement of the tumblers 16 and at the same time securing the bar 12 in the locked position. The key 25 can be then freely turned, the projection 25 passing free of the portion 22, till it completes one revolution, and can be removed through the slot 20. If required, also the second bar 12 can be locked in the same manner preferably by means of a second key with a differently shaped step-bit. The unlocking of the padlock is done in the same manner, with the only difference, that the keys are turned in the opposite direction than when locking. As soon as both the ends 12 of the bar 12 are free of the apertures 11, the bolt 8 is projected partly out of the rim 2 by the spring 9, till its outer end can be grasped by the operator and drawn out free of the opening 6, whereupon the padlock can be removed from the loops 24:.
It is understood, that I do not limit myself to any specific number of bars 12 employed in the padlock. In many cases one bar 12 will suffice while where additional i tumbler of each sethaving I-shaped slots to 5 receive the pins on the bars, and springs for operating the tumblers in one direction.
safety is demanded, three, four or more bars can be mounted in one padlock.
riaving thus described my invention, what 1 claim as new and desire to secure by Letters Patent is:
1. A padlock comprising a casing with an opening for the door-loops, a bolt slidably guided in said casing and adapted to pass through the door-loops, a spring proj ecting said bolt out of said casing, a plurality of bars slidably guided in said casing in transverse direction to said bolt, adapted to engage in apertures of said bolt, and further adapted to be operated each by a separate key inserted in succession into the padlook, a pluralityof tumblers mounted in groups, each group consisting of a plurality of tumblers mounted above one of said bars and acted upon by springs so as to rock in the casing, each tumbler being provided with a slot recessed at both ends and with two curved portions divided by a recess, and pins attached one to each bar and engaging in said slots of said tumblers, substantially as shown and described.
2. A look of the character described comprising a casing formed with an opening surrounded by a flange, the latter and the casing having alined openings, a bolt slidably mounted in the alined openings, said bolt having a slot, a spring for normally ejecting the bolt, a sliding bar mounted in the casing to engage the slot in the bolt, and lock same in the casing, means for guiding the sliding bar, a pin extending from the sliding bar, and a plurality of key operated tumblers mounted in the casing and adapted to lock the sliding bar in its retracted posi tion.
