FRED C. HAMILTON, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENT,
' TO FRANKLIN W. BROOKS, OF SAME PLACE.
IMPROVEMENT IN SEAL-BOLTS.
Specification forming part of Letters Patent No. 120,061, dated October 17, 1871.
To all whom it may concern:
Be it known that I, FRED C. HAMILTON, of the city, county, and State of New York, have invented certain Improvements in Devices for Locking Shackle-Pins, of which the following is a specification:
The invention relates to a device for applying a seal to a locking shackle-pin in such a way that the seal will be protected from injury while the pin remains in position, but must be broken in order to remove the pin.
Figure 1 is a front view, part of the casing being removed to expose the internal parts. Fig. 2 is a rear view, part of the casing being removed. Fig. 3 is a side view, partly in section. Fig. 4 is a top View, showing a pivoted cover over the seal. Fig. 5 is a perspective view with the locking cross-bar omitted.
A represents the stem or body of the shacklepin 5 B, its head; C, a removable sliding crossbar; and D, a dog, by which the spring-catch E,
' for locking and unlocking the device is pressed back. The cross-bar C has an interior cavity, c, containing' a spring, F, oi' any suitable construetion, and a mortise, c1, in its side, in which the spring-latch E works. At the side of the crossbar C, coming immediately over the spring-catch E, when in place, is a flange or projection, 02,1itting the slot al, at the side of the aperture a, in which the cross-bar is inserted. The spring catch E has a beveled edge, so that when the cross-bar C is pushed into place, this beveled edge, by being pressed against the side of the aperture,causes the catch E to yield, forcing back thespring F until after clearing the Wall a5 of the casing, when it is immediately pushed out by the spring. The spring-catch may be in the casing of the pin, and may catch in a notch of the cross-bar. The dog' D slides Within the casing, and is limited in its motion by the pin d. G is a pivoted cover over the seal-receptacle.
When used for securing a shackle or similar contrivance for which it is adapted, the crossbar G is withdrawn, the body of the pin inserted through the staple, and a seal, a3, inserted within the receptacle therefor, and the cross-bar again pushed into place within the aperture a. The iange c2 forces back the seal, pushing' one end under the top of the casing' at a4, while the other end is held in similar manner at a5, rendering it impossible to remove the seal without iirst destroying it. Said seal is preferably made of variegated glass, adapted to be represented by photography. As one end of the seal rests against a shoulder on the dog D, while the other end bears against the iiange c2, the dog cannot be pushed in so as to operate the latch E so long as the seal remains intact. The cross-bar C is now inserted, as before described, when the shackle is held between the hea-d B and crossbar C.
In order to withdraw the cross-bar C the seal is broken, the pieces removed, and the dog D pushed in, forcing back the catch E until it is iush with the side ofthe cross-bar C-the spring' F yielding to the movement-when the cross-bar may be readily removed, and the pin withdrawn from the shackle. rlhe casing A will be seenvto extend in front down as far as the lower end of the dog D, so as to prevent its being thrown up by an accidental blow, but a cavity, a6, at back, permits its ready elevation by the thumb or 1inger.
I claim as my inventionl. The combination of the shackle-pin A B, bar O, sliding dog D, and spring-catch E, substantially as and for the purpose specified.
2. The shackle-pin A B, and flanged cross-bar C, in combination with a spring-catch, E, seal a3, and dog D, substantially as and for the purpose specified.
