WHIP-LOCK.

Specification of Letters Patent.

Patented June 30, 1908.

Application filed February 27, 1908. Serial No. 418,154.

T 0 all whom it may concern:

Be it known that I, IIENRY O. LAUDER- MILGH, a citizen of the United States, residing at Halifax, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in l/Vhip- Locks, of which the following is a specification.

This invention relates to whip socket and more particularly to locking whip sockets, and has forits object to provide a whip socket of this kind which will be equipped with mechanism for securely and substantially locking the whip therein.

Another object is to provide a socket in which the locking mechanism will be so constructed that it may be chea ly manufactured and which will be such t iat it will be held positively in either locked or unlocked position.

Other obects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a vertical section taken through the casing and locking jaws in the plane of the eccentric disk and transversely of the key shaft. Fig. 2 is a View similar to Fig. 1 showing the parts in the opposite position. Fig. 3 is a detail section taken transversely of the socket, in the plane of the key shaft.

Referring now more particularly to the drawings, the present invention comprises a hollowcylindrical casing 5 of the usual type, within which there are disposed a pair of vertically extending jaws 6. A transversely ex tending horizontal key shaft 7 is journaled in the casing 5, and this key shaft is pivotally engaged in openings 4 in arms 9 which are formed integral with the jaws 6, these arms extending inwardly beyond the inner faces of the aws, to hold the latter in spaced relation. As shown, the jaws may be stamped from sheet metal. The upper end portions of the two jaws 6 are serrated to present teeth 12, and these serrated portions are bent inwardly so that the teeth are directed toward each other. The arrangement is thus such that a whip may be engaged by these teeth as will be. subsequently brought out.

Mounted upon the key shaft 7 between the arms 9, there is an eccentric disk 14, and engaged around this eccentric disk for loose movement of the disk therein, there is a strap 15. This strap is carried by a vertically extending rod 16, having a yoke 17 at its lower end. The spaced legs 17 of the yoke 17 have openings 18 at their lower ends, and these openings receive ahorizontally extending pivot pin 19.

Inwardly extending ears 20 are carried by the lower portions of the jaws 6, and these ears are located in the bifurcated outer end portions of the links 2]., and are connected therewith by means of pivot pins 22. The inner end of one of these links 21 is transversely reduced and is pivotally engaged upon the pivot pin 19, while the inner end of the other link 21 is bifurcated to present spaced portions 21 and 21, these portions receiving the reduced inner end of the first mentioned link therebetween, and being also engaged upon the pivot pin 19.

From the above, it will be seen that when the key shaft 7 is revolved, the eccentric disk 14 will be moved therewith, and the rod 16 will be moved vertically. Then the key shaft is moved to present the major portion of the eccentric disk downwardly, the rod 16 moves downwardly, bringing the links 21 into or approximately into a line with each other, and thus moving the lower end portions of the jaws 6 away from each other and bringing the upper gripping ends of the jaws toward each other to securely grip a whip disposed therebetween.

l Vhen it is desired to release the whip, the key shaft is revolved to raise the major portion of the eccentric disk, which brings the lower ends of the jaws 6 together and separates the upper ends thereof. At the same time, the rising eccentric disk engages the lower end of the whip, to move it vertically and release it from the gripping teeth 12. It will be understood that a suitable key is used to revolve the key shaft, and that the end of the shaft may be formed in a number of different ways to suit correspondingly formed keys. A guard plate A is engaged over the outer end of the key shaft which is thus formed, and prevents the gripping of the shaft by any instrument other than the key intended therefor.

l/Vhat is claimed is 1. A whip lock comprising a whip' receiving casing, jaws located within the casing for movement toward and away from each other,

a single pivot shaft for the jaws, and means for moving the jaws upon the pivot shaft,

said means being connected with the pivot 5 shaft for operation thereby.

2. A locking mechanism comprising a shaft, jaws pivotally' connected with the shaft, for movement toward and away from each other, an eccentric disk carried by the shaft, a rod connected with the eccentric disk for movement longitudinally thereby, and connections between the rods and the jaws, for movement of the jaws towards and away from each other, when the eccentric disk is 15 moved.

3. A device of the class described comprising jaw members pivoted between their ends for movement toward and away from each other, said jaw members having gripping members at one end, a revoluble shaft, an eccentric disk carried by the shaft a 'strap engaged with eccentric disk, a rod carried by the strap, and links pivoted to the opposite ends of the jaw members from the gripping members, said links being also pivoted to the rod.

. In testimony whereof I aflix my signature, in presence of two witnesses.
