LOCK FOR BICYCLE-STANDS.

SPECIFICATION forming part of Letters Patent No. 634,441, dated October 10, 1899. Application tiled October 29, 1897. Serial No. 656,737. (N0 model.)

To all whom, it may concern:

Be it known that we, JAMES S. CAPEN and HERBERT W. CHENEY, citizens of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Locking Devices for BicyclelStands; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speciiication.

Our invention has for its obj ect certain new and useful improvements in locking devices for bicycle-stands and it consists of the construction, combination, and arrangement of devices and `appliances hereinafter described and claimed, and illustrated in the accompanying drawings, in which* Figure l is a front elevation showing features of our invention. Fig. 2 is a side elevation. Fig. 3 is a view in section on the line 3 3, Fig. 1. Fig. 4 is a view in perspective of portions of the device, showing parts broken away. Fig. 5 is a detail view of the spring-actuated bolt D and related parts. Fig. 6 is a partial side elevation viewed from the side opposite that shown in Fig. 2, with parts of thevcase broken away. Fig. 7 i is av detail view of the key.

We carry out our invention as follows:

In the drawings, A A represent two locking jaws or arms arranged to be opened when the wheel is engaged thereby, said jaws closing automatically about the rim and tire ot' Vthe wheel to lock the bicycle and support it in position. Our invention aims to provide means for opening and locking said jaws, the locking mechanism being mainly contained or inclosed in a suitable case or receptacle B, which may be attached to a bicycle-stand (indicated at B) constructed in any suitable manner.

B2 denotes a door controlling access to the key (indicated at C) projecting loutward in a key-'chamber B3, to which said door B2 is the only means of access.

C is the keyhole of the locking device, to whichaccess may be had when the chamber Bs is opened.

The door B2 is automatically closed by a spring b and when closed is automatically locked by a spring-actuated b'olt D, the inner end of which projects into the chamber 'B3 and engages a latch b upon said door.

The bolt D is actuated bya head D', projecting to the exterior ot' the case or receptacle B, so as to be readily manipulated when free to move. The movement of said bolt D, how- 6o ever, is controlled by mechanism to be operated by any suitable` device inserted into the slot, the slot being indicated at b2, communicatingwitha runway b3, at the base of which is located one end of a lever E, upon which lever the operating device (indicated at F in Fig. 4) rests primarily, the weight of the operating device tilting the lever E, which is. fulcrumed, as at e. The lever E at its opposite end is provided with a head or analogous 7o device, (indicated at 61,) so as to prevent the manipulation of the bolt D and lock the bolt when the lever E is in normal position. a

Within the receptacle or case B is located a rocking bar G, which maybe journaled at one end in'a portion of the case B and at the opposite end in a support or bracket g. An arm G is Afixed in a transverse hole in the rocking bar G, said arm projecting at one eX- tremity underneath the lever E, the opposite 8o end of the arm projecting on the opposite Side of the rocking bar and provided with a crankaarni g'. The cylinder C2, into which the key C is iitted, is provided with an arm C3, having a shoulder c, engaging underalevel H, fulcrumed at its opposite end, as shown at h, and attached intermediate its ends to a locking-bolt J, as indicated at j, so as to lift the bolt J when the lever H is lifted by the turning of the cylinder when the key is op- 9o erated. The locking-bolt J is provided with an expanding-spring J and with a block J2 at its lower end to engage between the rear ends of the clamping-jaws A A, asV indicated in Fig. l. Said jaws are fulcrumed intermediate their ends upon suitable pins or screws, as indicated at a d. Adjacent to their fulcrums the clamping-jaws preferably have a toothed engagement onewith the other, as indicated at c', the jaws being provided with a roe sprin g CL2 to automatically close the forward It will be perceived that ends of the jaws.

when the lever ll is lii'led by turning the cylinder C the bolt .l is withdrawn with its block J ,perniitting the jaws A A to be opened. K denotes a spring, the upper end of which is arranged to engage over the adjacent end of the arm g', so as to hold the arm G' from' tilting` too far, and thereby preventing the lever E from descending, primarily, sufiiciently to allow the lever-operating device to 1o drop fully out of its runway, the lever-operating device being held in the runway until the upper end of the spring K is released from the arm g. Normally the arm g projects at a little distance below the upper end ot the i5 spring K sufiiciently to permit the lever E to be forced downward to release the bolt D, the descent of the lever E being sufficient to release the boltD, forcing the arm g' up into contact with the upper end of the spring K, such zo position being shown in Fig. -l-of the drawings.

\Vhen, however, the bolt D has been withdrawn and the door B2 opened and the key has been inserted in the cylinder C2 to turn said bolster,the turning ofthe cylinder releases the upper endet` the spring K from the arm g, permitting the lever-operating device to drop to its resting-place in the receptacle and altogether off from the lever E. To this end the spring K may be formed with a shoulder, indicated atk.) Said shoulder may siinplycontact with the key C in such a manner that when the key is turned the shoulder will be pressed outward to release the upper end of the spring. The key maybe locked inthe cylinder, so as to be prevented from removal until an operating device has been placed in the slot in any suitable manner-as, for cxample, the rocking shaft G may be provided with a pin, (indicated at 92,) one end of which 4o normally projects into a slot formed -in the key-cylinder, as indicated at c2, preventing the removal of the key until the pin g2 is released from said slot c2. This will occur when the rocking shaft G is actuated by the lever E striking the adjacent end ot the arm G', thereby rocking the shaft G and releasing the key.

L indicates the key-cylinder of an, additional lock to lock the bolt D, the key-cylin- 5o der L being constructed also to receive the key C, the. key-cylinder L being arranged, as hereinafter described, to withdraw the bolt D, so that the door B2 may be opened.

It will be seen that when the operator wishes to release his wheel from the lock he inserts the key into the key-cylinder L, thereby opening the door B2 to the chamber B3, permitting him to insert the key in the cylinder C2, thereby lifting the lever H and the bolt J with its 6o block J2, allowing the jaws A A to open and release the wheel. It will be obvious also that the rocking bar G having been restored to'normal position the key is locked in the key-cylinder C2 by means of the pin f/l and cannot be removed until an operating device has been deposited in the slot. A bicycle may thus be securely locked so as to prevent releasing the bicycle.

any other than the party holding the key from lhe device also insures the return of the key to the lock and locking the key therein, preventing the key from being carried off, while the device is in readiness for the next operation.

The case may readily be so constructed that the parts may be secured in place and the whole attached to the bicycle-stand B, so that all fastenings shall be out of reach.

The bolt D may be provided with a spring D?. the tumbler L, the operating-'spring D2 is placed between the frame B and the end of the bolt, and the bolt is provided with a pin d3 just above the opening through which the end of the tumbler extends. Upon the tumbler is formed an arm which engages with the pin d when the tumbler is turned by means of its key.

The bolt D is provided with a shoulder d upon its upper edge, with which the arm D4 upon the end of the spindle d3 engages. Upon the spindle is placed a spring d2, and upon the outer end of the spindle is placed the head D', by means of which the spindle is drawn outward when the lever E has its rear end depressed, so as to raise the head d from between the arm D4 and the boss on the inner side of the frame. When the head d is raised, the bolt can be operated by drawing out the spindle; but the bolt D can be operated with the proper key at any time by means of the tumbler, as shown in Fig. 5.

That we claim as our invention is- 1. A suitable inclosing case, two lockingjaws pivoted therein, and provided upon their inner sides with teeth which engage with each other, and a spring for connecting the ends of the two jaws for causing them to automatically close, combined with the vertical spring-actuated bolt, which has its lower end to catch between the upper ends of the jaws and to lock them in a closed position, a pivoted lever to which the vertically-moving bolt is pivoted, a normally inaccessible mechanism for operating the pivoted lever, and suitable means for giving access to the operating mechanism, substantially as shown.

A suitable inclosing case, two lockinglevers which are connected so as to move simultaneously, a spring connecting their upper ends for the purpose of causing their lower ends to close, a vertically-moving bolt which has its lower end to catch between the upper ends of the jaws, and a pivoted lever to which the vertically-moving bolt is pivoted, combined with the key cylinder C2 which is normally inaccessible and provided with the arm C3 which engages the pivoted lever Il, a rock-shaft, means for connection between this shaft and the key-cylinder to dog the key, an arm ixed transversely to the rock-shaft, the lever E operating the arm fixed to the rock-shaft and provided with a head at its outer end, and means, controlled by this head, for giving access to the nor- When the bolt D is to be operated by.
