Description

To all whom it may concern:

Atrium WOOLEN, or GROVE, NORTH DAKOTA.

sEAn-LooK.

Specification of Letters Patent;

Patented Nov. 19, 1912 Applicationfiled August 21, 1911'. Serial No. 645,101.

Be it known that I, ALFRED W OO LEN, a citizen of the United States, resldlng at Grove, in the county of Burleigh and State.

of North Dakota, have invented certain new and useful Improvements in Seal-Locks; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in automatic seals and is de' signed particularly and provides a devlce of this nature which is adaptable to car doors, gates, etc, and in fact allhasp locking devices. a

The present inventioncontemplates the provision of a solid sealing ring which wlll cooperate with a pin to lock the hasp 1n position, it being necessary to break said ring to remove the same and free the hasp.

With the above and other objects in view this invention consists in its construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawings wherein:

Figure 1 is a side elevation of seal e r fi bodying all the features of the present invention. Fig. 2 is a similar view of the locking pin. Fig. 3 is a side elevation of the locking pin. Fig. 4 is a vertical section,

- illustrating the locking pin in section.

The automatic seal, forming the subject matter of the present invention, comprises a plate having an orificed staple at one terminal thereof over which the hasp carried by the door is secured by a pin projecting through the orifice of said staple. This pin at its lower terminal enters into a socket member and cooperates with an oblique opening in the side of said socket member, which is adaptable to receiving the sealing ring previous to the entrance of the pin into said socket member. The pin is provided in its lower surface with an opening adapted to receive the sealing ring and automatically engage and lock the latter.

Reference being had more particularly to the drawings: 10 indicates a plate having the openings 11 at each terminal through which the means for securing said plate to a stationary object project. Adjoining the upper terminal of the plate 10 is a horizontal staple 12 having an opening 13 therein,l said opening being straight at its one s1 e. 12 is a socket member 14: having the longitudinal opening 15 therein, said opening 15 being shaped similar to the opening 13 of the staple 12. A vertical slot 16 pierces the Disposed directly below the staple side of the socket member 14 slightly above I the base of the opening 15 in said socket member. The rear terminal of the slot 16 connects with a curved oblique groove, or slot 17 which extends to the forward face of the socket member. This construction permits a solid sealing ring 18 to be inserted in slot 17 and thereby be forced into the slot 16 and be retained transversely in the opening 15 at an elevation above the base thereof.

The locking pin 19 is provided with an enlarged slot head at its upper terminal said head being connected with any suitable retaining means to prevent the loss of said pin. In the cross section the body of the pin 19 conforms with the formation of the openings 13 and 15 of the staple and sleeves 12 and 14: respectively. In the lower flat surface of the pin 19 and adjoining the former terminal thereof is a longitudinal opening 20 cooperating with the transverse opening 21 which forms the

arms

22 and 22. The lower "side of the forward terminal of the blocking pin 20 is tapering under said terminal thereby causing the arm 22 to be at a higher elevation than the arm 22. The forward terminal of said arm 22 is tapered to facilitate the entrance of the sealing ring 18 into the opening 20 as will hereinafter be more fully described.

From the foregoing it will readily be understood that the sealin ring 18 is placed in the slot 16 as hereinbefbre described previous to the entrance of the pin into the opening 15 of the socket member. The hasp 23 is then placed over the projection 12 and the pin inserted in the opening 13 of said projection and forced into the passage on opening 15 of the socket member 14. This movement causes the ring 18, due to the tapering terminal of the pin 19, to force the arm 22 toward the front of the pin after which the sealing ring, through the instrumentality of the tapering terminal of the arm 22 enters the longitudinal opening 20. After the ring has entered the longitudinal opening 20, the arm 22 springs back toits original position locking said ring therein. It is, therefore, necessary, in order to remove the pin 19 from the sleeve, to cut or otherwise break the ring 18 and displace the same from said sleeve previous to the removal of the pin.

Having thus fully described my invention, what I claim as new and desire to se cure by U. S. Letters Patent is: 7

1. An automatic seal comprising in com bination with a plate, of a staple carried thereby, a socket member alined with said staple, a hasp adapted to coeperate with the staple, a sealing ring, means whereby said sealing ring may be inserted in said socket member and arranged transversely therein and spaced from the base thereof, a pin for cooperation with the staple and socket member and alined arms formed from said pin adapted to automatically engage said ring and permanently secure the same in engagement with said ring.

2. An automatic seal comprising in combination with a plate, of a staple carried there- 3. An automatic seal comprising in combination with a plate, of a staple carried thereby, a socket member in alinement with said staple, said socket member being pierced by a straight, transverse opening, and an oblique outwardly extendin opening communicating therewith, a sea ing ring adapted to be inserted in said oblique opening and rest in said straight transverse opening, in a raised position-from the wall of said socket member, a pin for insertion in the staple and.

socket member aforesaid, and a pair of arms formed in one side of said pm, said arins being in various 'el'e'vation's and form a s ce for the reception of the said sealing ring.'

4. An automatic seal comprising a socket member having longitudinal passage therein and a vertical s1ot'co6perating with said passage, said vertical slot oining an oblique slit, a sealing ring adapted to be placed within said oblique slit and be retained in said vertical slot above the base of thepassage in said socket member, and a locking pin cooperating with said socket member for automatically engaging "said seal and be retained thereby. p

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

ALFRED VVOOLEN.
