CYCLE-LOCK.

SPECIFICATION forming part of Letters'PatentNo. 623,184, dated April 18, 1899.

Application filed January 21,1898- Serial No. 667,445. (No model.)

To rtZZ whom it may concern.-

Be it known that I, SEBASTIAN SCHADLE, of

Gronenbach, near Allgitu, in the Empire of Germany, have invented Improvements in Oycle'Locks, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates to an improved cycle-lock for preventing the cycle from being used by unauthorized persons, the construction of said lock being such that a bolt projecting from the lock stops one of the two pedal-cranks, and thus prevents the whole pedal mechanism from executing the'slightest movement. p

The invention is represented in the accompanying drawings, in which Figures 1 and 2 are different horizontal sections. Fig. 3 is a vertical section through the lock; Fig. at, an upper view of the look, while Figs. 5 and 6 illustrate the method in whichthe lock is arranged on the velocipede.

In the interior of the look a bolt a is arranged which so projects from the lock that when being slid forward it will grip one of the cranks I), and thus prevent either of the cranks from further rotation. This bolt is slid in and out by hand, and the point in question solely is to retain the bolt in either of its positions and to prevent the bolt when in the closed position from being moved back by unauthorized persons. For this purpose in the interior of the-lock a tumbler d, capable of turning on a pivot c, is arranged, against the nose 8 of which bears the bolt a when in either of its extreme positions. Through the action of a spring g the tumbler d is constantly pressed against the bolt, so that the latter can only be brought into the open or closed position if the tumbler d has been properly moved backthat is to say, brought into the position shown in dotted lines in Fig. 1.

The drag-bar 7L may be actuated so as to move aside the pin 1', which is fixed to the tumbler (Z, and thus simultaneously shift the said tumbler d. This drag-bar h is rotatable upon a transverse fence-bar 7a, which can-be moved between the guides Z, and which is moved by means of a knob m, projecting from the lock-casing. The limits of movement of the knob is determined by the angular slot 77., arranged in the upper casing of thelock, from which the said knob projects, the operation being such that the knob is first moved out of its highest position into that represented in Fig. 4 and is subsequently moved toward the left. By the latter portion of the movement the drag-bar his turned toward the left, and simultaneously therewith also the tumbler d, retaining the bolt, is moved toward the left.

It is evident that the knob must first be turned out of its initial position into the'knee of the slot before it can execute the left-hand movement by which the tumbler d is moved.

The principal idea on which the invention is based is that the movement of the knob out of its initial position down to the knee of the slot can only be executed when the four hands 1* occupy a certain relative position. Now as, on the onehand, very many combinations are possible with these four hands .and as, on the other hand, only the ownerof the cycle is aware of the position required for placing the look into its opening positionit is evident that for any unauthorized person it is next to impossible to open the lock. Each of the hands is connected to a disk or turnbler 0, each of which latter is provided with a gating .9, Figs. 2 and 3. The connection between the hands and the tumblers is of course such that onehand is connected with one tumbler by means of an axle,while the other hand, turning about the same axle, is connected with the second tumbler by means of a small tube or sleeve traversed by the before-mentioned axle. The fencebar lahereinbefore referred to, is provided with two fences t, which are enabled to engage with the gatings s of the tumblers. The said fence-bar 76 thus can only be moved downward to such an extent that the fences come into contact with the peripheries of the tumblers. Consequently the knob m, connected to the fence-bar by means of the drag-bar h, is prevented from being slid down to the knee of the slot and accordingly the pivotal tumbler 61 cannot be moved out of its locking position. After each displacement of the bolt 00 the tumbler dis re turned to its locking position, Fig. l, by a corresponding rotation of the drag-bar h. Thus the movement of the bolt a required for looking as well as for releasing the wheel can only be effected if the hands are so placed that the gatings of the tumblers lie opposite the two fences 2 This given position of the hands may of course be altered by displacing them upon their axes or by imparting to them another relative position on mounting them upon their axes.

The lock admits of being very rapidly opened and closed by passing the four hands into the proper predetermined position, only known to the owner of the cycle. The main advantage of the lock,however, consists in the fact that no key is required for opening and closingthe look, so that the cyclist is not exposed to the inconvenience'of losing his key.

What I claim, and desire to secure by Letters Patent of the United States, is

1. A cycle-lock comprising a locking-bolt mounted in a suitable casing, a pivoted tumbler mounted in the said casing and adapted to engage the inner end of the said bolt for holding the same in place, a drag-bar for moving the said pivoted tumblerout of engagement with the bolt, and means for preventing the movement of the drag-bar, substantially as described.

2. In a cycle-lock, the combination with a bolt mounted in a suitable casing, of a pivoted tumbler mounted therein and adapted to engage the inner end of the said bolt for holding it in its extreme positions, a drag-bar also pivotally mounted in the said casing and adapted to have a radial movement in order to engage the said tumbler for moving it out of engagement with the bolt, and means for preventing the movement of the drag-bar when the bolt is in its locked position, substantially as described.

3. In a cycle-lock, the combination with a suitable bolt, of a pivoted tumbler for engaging and controlling the said bolt, a fence-bar also mounted in the said casing, a drag-bar pivoted to said fence-bar and adapted to engage the pivoted tumbler for releasing the bolt, and means for controlling the movement of the fence-bar, substantially as described.

4t. In a cycle-lock, the combination with a bolt, of a tumbler for controlling the same, a fence-bar carrying fences, a drag-bar pivoted to said fence-bar and adapted to swing upon said pivotal point to operate the said tumbler, and permutation-til mblers for controlling the movement of the fence-bar, substantially as described.

5. In a cycle-lock, the combination with a suitable casing, ofa bolt adapted to move therein, the outer end of the said bolt being provided with engaging arms for engaging the crank of the cycle when the bolt is in its outward position, a pivoted tumbler in the said casing adapted to engage the rear end of the said bolt for holding it in its extreme positions, a drag-bar pivotally mounted in the said casing and having a stud which projects exteriorly thereof through a slot formed in the said casin g, the said slot being approximately L-shaped, whereby the stud upon the said bar must be brought to the lower portion of the slot before it can move laterally for engaging the pivoted tumbler, and means connected to the drag-bar for engaging notched tumblers, the construction beingsuch that when the said means engages the said notches, thestud and arm may be moved so as to swing laterally for disengaging the bolt of the lock, substantially as described.

6. In a cycle-lock, the combination with a suitable bolt, of a pivoted tumbler for controlling the same, a fence-bar provided with two or more fences, a drag bar pivotally mounted on the said fence-bar, and permutation-tumblers provided with gatings and adapted to engage the fences, and means for preventing the movement of the drag-bar upon its pivotal point when the fences are out of engagement with the said gatings, substantially as described. I

7. In a cycle-lock, the combination with asuitable bolt, of a tumbler for controlling the same, a fence-bar carryingfences, a drag-bar pivoted to the said fence-bar and adapted to operate the said tumbler, permutation-tumblers having gatings, exterior pointers secured to said permutation-tumblers for indicating their position, and a projection formed upon the said drag-bar adapted to engage a slot formed in the casing, the construction being such that the drag-bar cannot be moved so as to operate the bolt-tumbler except when the gatings of the permutation-tumblers are in a position to receive the fences of the fencebar, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

SEBASTIAN SCI-IADLE.
