COMBINATION BICYCLE-LOCK.

SPECIFICATION forming part of Letters Patent No. 576,835, dated February 9, 1897.

` Application filed May 9, 1896. Serial No. 590,932. (No model.)

.To all whom t may concern:

Be it known that I, SAMUEL W. COLLINS, a citizen of the United States, residing at Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in a Combination Bicycle- Lock; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the 1o art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in combination bicycle-locks of that class that arev permanently attached to vthe bicycleframe and adapted to securely lock the steering-post against turning Within the framezo head, and has for its objects, iirst, to provide a lock of that class that is always in position; second, that can be locked and unlocked without the use of a key; third, that is susceptible of a great number of changes of the corn- 2 5 bination; fourth, that may be changed readily from one combination to another; fifth, that will add but little Weight to the bicycle; sixth, that will not be in the way of the rider, and, seventh, that may be built upon the bicycle 3o or attached thereto after the machine is finished.

With these objects in view my invention consists in the construction and combination of parts shown in the accompanying draw- 3 5 ings, and described in the following specification.

In the drawings, Figure lis a view of a portion of a bicycle, showing the lock thereon. v

Fig. 2 is a cross-sectional view taken on the 4o line 2 2 of Figs. l and 3. Fig. 3 is a vertical sectional view of the lock and that portion of the bicycle-frame to which it attaches. Fig.

4 is a top plan view showing the outer rings or tumblers in section. Fig. 5 is a crosssection of one of the outer rings or tumblers. Fig. 6 is an enlarged fragmental view of a section of one of the inner notched tumblers and the outer ring. Fig. '7 is a perspective View, partly in section, of the lock-opening ring or tumbler, and Fig. 8 is a sectional View showing a modified form of construction.

A is the handle-bar.

B is the frame-head.

' C is the steering-post.

D is the horizontal top tube of the frame.

E is the central core sustaining the locking-bolt.

F is the retaining-ring, which holds the tumblers and friction-rings up against each other.

G is the lock-operating ring or tumbler.

H H are the separating-rings between the tumblers.

I I are vthe notched inner tumblers.

Y J J are the outer rings or tumblers having the combination-numbers.

K is the locking-bolt.

L is the spring which presses the bolt K forward when it is released by the tumbler G.

The outer rings J are provided with a series of numbers and graduations on the outside, and each of them have the V-shaped pro jection a located upon the inner face at the desired point. This projection ay enters the Vshaped notches b, extending across the outer faces of the tumblers I. The tumblers I are each provided with a slot c in the inner face, and the outer face above the slot c is plain, as at d.

The operating-ring Ghas on its inner face an open collar e, one end of Awhich is narrower at the opening than the other and gradually widens toward the center. It is also provided with a shield f, which is adapted to project over a portion of the outer rings J, and has a semicircular notch g in its outer edge, whereby the screw h, securing the retaining-ring F, may be removed. It is also provided with a mark fr', which is directly over the openin g in the open collar e, secured to the inside. The notched tumblers I are not as wide as the outer rings J, and the dif ference in width is lled by the separatingrings H. These rings are immovable on the tube D and have an opening corresponding with the Width of the bolt K, thereby allowing the projections j thereon to pass said rings Il. These rings serve to separate the tuniblers I and prevent the adjacent tumbler from turning by friction when the next one to it is being turned.

The bolt K is adapted to slide in a slot l1; in the core E, and in the slot 7c in the hori- Zontal tube D, and has the projections J upon its upper edge, which are adapted to pass the slots c in the notched tumblers I, the openings in the separati ng-rin gs II, and the opening in the open collar e. The lower part of the rear end of the bolt K is cutaway and is provided with a stud I, around which one end of the spring L is coiled. The core E has an opening of suiiicient size to receive the coilspring L. The front end of the bolt Kpasses through an opening in the Wall of the frame-head B and enters a slot on in the steering-post C, when said steering-post is turned so as to bring the slot m opposite the bolt K. The spring L presses the bolt forward into said slot m, provided the ring G is turned so as to bring the opening in the open collar c in line with the projections upon the bolt K. When in this position, the shield j' will be opposite the side of the tube D and the mark i will be directly on top of said tube. Then movedin this position, the semi.- circular notch g passes the screw h, and thereby preventsits removal. The tumblers I and the outer rings J, which move together by rea-son of the notches ZJ and the projections ct engaging each other, are then turned, which carries the slots c in the tumblers I out of line with the projections j upon the bolt K, thereby preventing the bolt K slipping back, and holding the forward end in the slot m in the steering-post. In this position the operating-ring G cannot be rotated by reason .of the rear projection j on the bolt K being held against a rear movement by reason ofthe forward projections j not being able to pass the notched tumblers I. The slot m being in the side of the steering-post, it will be seen that the front wheel will be turnedsidewise when locked, thus rendering it impossible to propel the bicycle except in a small circle.

To unlock the wheel, the rings J are turned until the numbers on the ring to which the combination is set come opposite the mark 'i upon the ring G. This brings the openings c in the tumblers I in line with the projection j on the bolt K. The ring G is then turned, the rear projection j on the bolt K being engaged by the narrow end of the open collar, and thereby draws the bolt K back. This brings the other projections into the slots c on the inside of the tumblers Lwhich prevents them from being turned. The shieldfis then `on top of the tube, as shown in Fig. 1, and

covers the numbers to which the combination is set and prevents any one from observing the numbers of the combination when the wheel is unlocked. The Wheel is quickly locked by turning the ring G until the mark t is opposite the numbers of the combination, then turning the steering-post until the opening m comes opposite the bolt K.Y A slight turn of the rings J prevents the withdrawal of the bolt and throws the combination out. To change the combination, the screw 7L is removed and the securing-ring F slid back on the tube D. The ring Gand separating-ring I-I are slid back against F and the outer ring J slipped off of the notched tumbler I. The ring J is then turned until the desired number comes on top, directly opposite the plain portion CZ of the tumbler I, and is then slipped back. when the Vsh aped projection a will enter a corresponding V-shaped notch in the tumbler J. Either one or both of the sets of numbers may be changed in the same manner, when all the rings and tumblers are pushed back into place and the screw h again inserted, holding the lock securely `in place.

It will be seen that the combination is susceptible of a large number of changesand that it will be impossible to open the lock without working the combination or destroying the frame.

In Fig. 8 is shown a modiiiediiform of the lock adapted to be attached to a bicycle already built, as it is obvious the constructions above described can only be advantageously attached when the frame is being put together, The arrangement and .construction .of the rings J and the tumblers I are the same, and the bolt K operates in the same manner.; but the lock-operating ring G is located next the steering-post, and the core E has a flange `n on the outer end, which `is equal in diameter to the diameter of the rings J, and serv-es to hold them in place on the core The bolt K is slightly dilterent in shape, but the principle and manner of locking is the same as in the lock above described.
