PATENT BERNARD JOSEPH GIEBEL AND XVILLIAM ARTHUR PARK, OF FREMONT, OHIO.
SEAL-LOCK.
SPECIFICATION forming part of Letters Patent No. 653,799, dated July 17, 190i).
Application filed M 1 4, 1899- Renewed March 8, 1900. Serial No. 7,928. (No model.)
To ctZl whom it may concern.-
Be it known that we, BERNARD JOSEPH GIEBEL and WILLIAM ARTHUR PARK, citi- Zens of the United States, and residents of Fremont, county of Sandusky, and State of Ohio, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar characters of reference indicate corresponding parts in all the figures.
This invention relates to improvements in seal-locks; and the object thereof is to provide a device of this class which is so constructed as to prevent tampering therewith without leaving evidence of such tampering.
The invention will be hereinafter fully described, aud specifically set forth in the annexed claim.
In the accompanying drawings, forming part of this specificatiomFigure 1 is a front elevation'of our improved lock having a portion thereof broken away. Fig. 2 is an end elevation. Fig. 3 is a sectional plan View on the line :0 of Fig. 1. Fig. 4 is a longitudinal sectional elevation on the line 3 y of Fig.3. Fig. 5 is a face view of one of the plates forming part of the device. Fig. 6 is a face view of a seal used in combination with the device, and Fig. 7 is a side elevation of a key adapted for operating the look.
In the practice of our invention we employ ordinary locking means comprising a springactuated hook A and a cross-bar b for engagement therewith, the bar forming part of a casing B, which is secured to the framework of a structure to which the device is attachedfor instance, a freight-oarand the hook A being mounted within a casing C. This said hook is pivoted upon a spindle Ct, which projects from the inner wall of the said casing O, and it normally rests upon alug to", also projected from the said rear wall of the casing, and the hook is maintained in a normallyhorizontal position by means of a plate-spring D, secured to a projecting lug d of one end wall of said casing. The said mechanism is covered by means of a partition or plate E, located back of the front wall 0 of the casing O, and a horizontal keyhole c is supplied through the said plate for guiding the key which operates the locking mechanism. Between the plate E and the front Wall 0 of the casing O is a recess e, which'is formed by means of a rib 6 extended from the face of the plate E, and this said rib bears against the inner face of the front wall 0 of the casing O. This said recess is adapted for retaining a seal 1, as will be hereinafter described.
The front wall 0 of the casing O is supplied with an aperture 0', which has recesses 0 extended therefrom for guiding the key, these said recesses exactly registering with the horizontal portion of the keyhole c. This aperture is of a considerably-larger diameter than the keyhole for the purpose of exhibiting the seal 1, contained within the recess 6. The seal is composed of fragile material, preferably paper, and it is provided upon one corner thereof with an extension 2 for the purpose of removing it and for placing it in position. The seal may also be supplied with any suitable printed matter upon the space 3, which is visible through the recess e.
The several parts of the lock-casing are held together by means of screws 4, which engage studs or projections 5, forming part of the rear wall of the casing, and the device is adapted to be attached to a car-door by means of screws,which maybe passed through the apertures 6, formed through the walls of the casing, similar apertures being formed through the plate E. The casing for engaging the hook when the door is in alocked position is also provided with apertures 6 for receiving screws for fastening the same to the framework of a car.
To prevent the lock from being manipulated without the use of a proper key, annular projections 7 are formed around the post 8, and these said projections engage recesses 9 of the key 10. A
The casing B is provided with a flange or extension 19', which laps over one edge of the front wall a of the casing O to prevent tampering with the seal, and the whole face of the said front wall 0 is covered, by means of a hinged plate 0, to prevent the seal from being injured by moisture during inclement weather. In the operation and use of the device-for instance, when it is placed upon a car-doorwhen it is desired to lock and seal the car it is simply necessary to place a seal 1 within the aperture c and close the door, which, owing to the construction of the lock, will fasten automatically. Then in order to unlock the same it is first necessary to fracture the fragile seal before the key can be inserted, and it is obvious that should said seal be fractured by persons without authority the act can be readily detected.
We do not confine ourselves to the specific details of mechanical construction as herein shown and described, as it is obvious that under the scope of our invention we are entitled to variations, and our invention can be employed in combination with any springlock.
Having thus described our said invention, what we claim as new, and desire to secure by Letters Patent, is-
In a seal-lock, the combination of a casing embodying afront plate having anaperture therein, an auxiliary plate located back of said front plate and having a keyhole which registers with the said aperture, a recess between the two said plates, a fragile seal contained within the said recess, and having the end portion projecting from said recess, and the supplementary casing having the flange or extension which laps over the edge of the front wall of the main casing and covers the projecting end portion of the seal, substantially as shown and described. V
In testimony that we claim the foregoing as our invention we have signed our names, in the presence of two witnesses, this 21st day of February, 1899.
