Application filed February 15, 1897. Serial No, 623,461. (No model,)

To all whom it may concern:

Be it known that I, Oscar Damon, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, 5 have invented certain new and useful Improvements in Locks, of which the following is a specification.

This invention relates to locks and latches, and particularly to a lock for bicycles, bagro gage, and other portable articles to lock the same against removal or transportation, such lock being as readily adaptable for use as a pad or hasp lock; and the object of the invention is to provide a new and improved lock ^r5 of special construction and arrangement of parts.

A further object of the invention is to provide a peculiar and novel means for locking the separable parts of the lock together.

2o The invention consists in the novel construction and arrangement of parts, and resides, essentially, in the telescoping members or parts and means for locking them together.

In the accompanying drawings, forming 25 part of this application, Figure 1 is an ele. vation of the lock with the members in telescopic position locked together. Fig. 2 is a longitudinal sectional view with the members unlocked. Fig. 3 is an enlarged sectional 30 view on the line a; x, Fig. 2, showing the key in position to unlock the members. Fig. 4 is an edge view of Fig. 1. Fig. 5 shows a modified screw projection. Fig. 6 is a modified key.

The same numeral references denote the 35 same parts throughout the several figures of the drawings.

The lock members consist of a bar or rod 1, forming the shackle, preferably U-shaped, having upon one end teeth 2 and a like40 shaped tube or hollow sleeve 3 to receive the ends of the bar or shackle 1 in telescopic position. The other end of the bar 1 has a longitudinal groove 4, terminating in an L-shaped groove 5, which engages a lug 6 on the inside 45 of one end of the tube or sleeve 3, so that the shackle may be operated to slide in or out of the sleeve the whole length of the said groove 4 with the toothed end of the shackle' in or out of the sleeve without separating the 50 shackle from the sleeve, said shackle being turned to have the lug 6 engage the L-shaped groove 0 to put the toothed end of the shackle out of the line with the sleeve or to separate the sleeve entirely. The other end of the sleeve 3 has integral flanges 7, between which 55 is confined a toothed plate 8, adapted to be moved transversely to the sleeve 3 and provided with a screw-threaded projection 16. , The plate 8 is controlled by a plate-spring 10, provided with an aperture 10% having its 60 bearing upon the plate 8 and upon the top or cover 11, having an aperture ll^a, and which may be secured upon the flanges 7 to the end pieces 12 in any suitable manner. These flanges 7 and the end pieces 12 form the cas- 65 ing for the movable locking-plate 8 and spring 10,said ends 12 having upon the inside tongues 13, engaged by a groove 14 in the ends of the plate 8 and notches 15 in the ends of the spring to keep these parts against displacement and 70 to insure the spring and plate against tilting or any frictional contact that would impair the free operation of the same. The plate 8 is provided with a screw-threaded projection 16. The screw-threaded end of the key 18 75 has a collar or shoulder 19, adapted to engage the top or cover 11 when the key is screwed through the apertures 10^a and ll^a on the projection 16, and by a continued turn of the key the plate is raised out of engagement with the 80 teeth of the shackle, which unlocks the latter from the sleeve 3. It is obvious that immediately upon removing the key the soring 10 will force the locking-plate 8 back to the sleeve until the teeth of the plate project into the 85 sleeve in the path of the shackle.

A chain 20 may be slipped over the shackle and a like chain may also be applied to the sleeve for the purpose of locking articles to it as desired, which cannot be reached by the 90 shackle. It will be observed that the shackle may be extended far into the sleeve or it may be extended far from the sleeve, yet in either position it is locked to the sleeve by pressure of the spring upon the toothed plate. 95

Referring to Figs. 5 and 6, a modified form of screw projection and key is shown. The projection has a central opening 21 or is hollow with a square thread 22, having notches 23 upon opposite sides to admit the prongs 24 100 of the key 25, while the central projection 26 of the key enters the opening 21 to insure the

596,237 proper centering of the key. The operation of this form of key and screw projection is the same as that hereinbefore described.

It will be readily seen that the application 5 of my lock is unlimited, and I therefore do not wish to confine myself to its adaptation, nor to any particular size, shape, or manner of making; but,
