SEAL.

Specification of Letters Patent.

Patented May 18, 1915.

Application filed April 20, 1914. Serial No. 833,068.

To all whom it may concern Be it known that I, PHILIP J. MITTEN, a citizen of the United States, residing at Oakwood Village, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Seals, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to seals such as are employed for preventing the removal of fastening devices by means of which two parts are fastened or locked together and is more particularly designed for use in connection with fare boxes to prevent the removal of the top of the case, which would permit of access being had to the interior of the box. The seal commonly in use for such purposes consists of a wire having its ends brought through an opening in a lead disk which is then compressed on the ends of the Wires to retain them in position and prevent the withdrawal of the wire from the fastening device through which is has been passed. In practice, however, some unscrupulous persons have been able to loosen the wire in the disk and remove the same, thus releasing the fastening device, and to subsequently return the ends of the wire to the lead disk and re store the seal to its normal appearance.

The object of the present invention is to provide a seal of this character which cannot be removed or separated to permit the fastening device or devices to be removed without destroying the seal or a part thereof; and further, to so construct the seal that the broken or destroyed part thereof cannot be readily duplicated and the duplicate part substituted for that which has been destroyed.

To this end it is a further object of the invention to provide a seal in the form of an elongated bar made up of two or more parts, the adjacent ends of the parts being connected one to the other by pressing a portion of one part into a recess in the other part, and so arranging the parts that a lengthwise movement sufficient to separate them cannot be imparted thereto without destroying one of the parts, thereby preventing the parts being separated by a lengthwise pull.

In the accompanying drawings Figure 1 is a plan view, partially broken away, of the top of a fare box. Fig. 2 is a side elevation of the upper portion of a casing forming a part of the fare box and the top for that casing. Fig. 3 is a plan view of the seal and fastening devices. Fig. i is a detail sectional view of one end of the seal and one of the fastening devices. Fig. 5 is a detail view of the blank from which one part of the seal is formed.

In these drawings I have illustrated one embodiment of my invention and have shown the same as applied to the casing and top of a fare box, but it will be understood that the invention is capable of being applied not only to difierent parts of a fare box where it may be desired to use a fastening device, but also to any other device in which it is desired to seal the fastening devices against removal.

In the accompanying drawings a portion of the casing forming a part of the fare box is shown at 1 and secured to the end of this casing is a top piece 2. These structural parts of the fare box form no part of the invention and are shown here merely to illustrate the fastening devices and the seal. The top may be secured to the casing 1 by the use of any suitable fastening device. In the present instance the top is provided on one side with a depending lug 3 having a projection 4 adapted to enter a hole 5 in the upper portion of the adjacent wall of the casing. In the present instance the projection 1 is in the form of a stud mounted in a hole in the lug 3, having its end upset after the manner of a rivet and having an enlarged head forming the projection and tapered to facilitate its entrance into the hole 5. As here shown I have provided this side of the top with a single lug and fastening device, but obviously any suitable number of these devices may be employed. The opposite side of the top is provided with one or more lugs 6. In the present instance I have shown two. These lugs are adapted to extend inside of the adjacent wall of the easing and after the projection a has been placed in the hole 5 and the lugs 6 moved into their positions within the adjacent wall of the casing, it will be impossible to remove the projection 4 from its opening without first removing the lugs 6 from their positions within the casing. Suitable fastening devices are provided to retain the lugs 6 in their positions within the casing. Preferthreaded pins.

these portions of the pins are provided with ably, but not necessarily, these fastening devices are of such a character that rotatory movement is necessary to their removal and to the releasing of the lugs 6.

The particular form of fastening device here'shown comprises a screw-threaded pin 7 having an enlarged head 8 and adapted to extend through an opening in the wall of the casing 1 and to be screw-threaded into a screw-threaded opening in the lug 6 until the head 8 is brought into contact with the Wall of the casing. So long as the parts remain in this position it is impossible to separate the top from the casing without destroying one or the other of these parts.

To prevent the removal of the fastening devices a locking device orseal is provided which will prevent therotation of the screw Preferably this seal is in the form of a bar or rod extending between the two fastening devices, where twonsuch,

vention here illustrated the enlarged-headS of each fastening device is provided with a transverse aperture 9 through which extends a pin 10 forming a part of the seal. pin has a head 11 to limit its lengthwise movement in one direction and the aperture 9 is enlarged at its outer end, as shown at 12, to receive this head. Preferably the head is rounded as shown in the drawings to prevent it being grasped by a pair of pliers or other implement. The inner end of each pin 10 projects some distance beyond that side of the fastening device opposite the enlarged portion 12 of the aperture, and

recesses 13 which, in the present instance, are in the form of annular grooves having a relatively great width. Arrangedbetween the two fastening devices and connected with the inwardly projecting parts of the pins 10 to form the intermediate portion of the seal is a rod 14 having its ends hollow to receive the adjacent ends ofthe ins 10. Preferably this rod is in the form of a tube,

of brass or other ductile material, andisof a length but slightly less than the distance betweenthe two fastening devices. Infplacing-the seal in position it is necessary that the intermediate portion or ductile body 14' should be first placed in position and then the pins inserted in the apertures 9 in. the fastening devices and thrust in to. the adj a "55 cent ends of the tubular body. 'Afterthe The,

This

parts have been assembled in this position those portions of the tube'or body which extend about the recesses 13 are compressed the seal. It will be obvious that after this by means of a suitable implement to force the metal thereof into the recesses, thus firmly connecting the pins with the body of connection is made it will be'impossible to rotate either of the fastening devices without destroying the seal. The ends of the body being arranged close to the respective fastening devicesprevents the heads of the:

pins being moved outward into a position in which they could be gripped and a lengthwise pull exerted thereon. Likewisethis arrangement of the body 14 prevents longitudinal thrusts being exerted upon this body in such a manner as to gradually loosen the grip of the compressed portions thereof on the pins. By making the recesses-or'annular grooves 13 of a width greater thanthe compressed portion of the. tube or bodyit is not only easier to locate the recess and press the metal intov the same,but the tube may have. a slight longitudinal movementlon the pins without bringing the compressed portions thereof into engagement with the shoulders at the ends of the recesses, which engagement would, if repeatedly made in a forceful manner, gradually force out the compressedportions of the-tube. To prevent a duplicate of the ductile body or tube 14 being provided by unauthorized persons and substituted for the tube of the seal after the latter hasfbeen broken, I prefer to provide the tube with a distinctive marking which is engraved, punched, -or otherwise formed therein as shown at 15 and which it would be difficult to duplicate. Moreover,

the implement employed to compressor crimp the material of the tube into the re.- cess may be of such a character asto form a distinctive mark, as shown at 16, which mark- 7 it would be difiicult to duplicatewitholli the use of this particular tool.

The operation and manner-of use of the. device will be readily understoodfrom'. the

foregoing description and itvwill be apparent that the device'willveffectually prevent the removal of one'or both fastening de;

vices without the destruction of some part, of.-

the seal. Further, that the; device is 'of a simple, inexpensive character which canbe readily applied to the fastening {devices It will also be apparent-that while I have shown the seal as applied to two fastening devices it will operate equally well with a single'fastening device by providing a suitable support for that end of the seal opposite the end connected with the fastening device, to take the place of the support formed by the other fastening device. Further, it will be apparent that the ductile tube. or body'may be formed in any suitable manner,

as by using a section of drawn tubing or 180 by die casting, but in the present instance I have formed the same from a blank of metal, which blank is shown at 17 in Fig. 5, and is adapted to be bent into the form of a tube.

'While I have shown and described one embodiment of my invention, it will be understood that this has been chosen for the purpose of illustration only and that I do not wish to be limited to the details of construction shown and described, for obvious modifications will occur to one skilled in the art.
