Improvements in Seal Locks.
I, JOHN ARTHUR UPSHUR, of 108 North Beech Street Richmond, in the
County of Henrico, and State of Virginia, United States of America, Gentleman,
do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention relates to seal-locks for fastening car-doors, the object being to
provide a lock of this kind which shall effectually defeat all attempts to tamper
with the same without detection, and give protection to the officers and employees
of a railway company, as well as to the persons, or firms, transacting business with
the road.
It is the purpose of my present invention to simplify and improve the construction
and operation of seal-locks; to reduce the cost of their manufacture; to provide a
construction of extreme simplicity, which will defeat every possible attempt to
tamper with the lock and open the door of the car, without rupturing the metallic
tag, and to so form and mutually adapt the two metallic portions of the lock that
they may be assembled, combined and attached to the car in the condition in which
they come from the mold, without any intermediate process of finishing, and
without drilling, or other operation, for making a pivotal connection.
It is my further purpose to provide a seal-lock having such construction that the
introduction of the metallic tag produces a curvature or change of form therein,
whereby it is positively engaged with a rigid part of the structure from which it
can only be released by rupture.
It is my further object to provide a seal-lock of the type last mentioned, and to
combine therewith a metallic tag so formed that when inserted it shall not only be
converted automatically into a part of the lock, but shall also furnish an absolute
safeguard against the insertion of any instrument whereby the disengagement of
the tag without rupture might be attempted.
It is one purpose of my invention also, to provide for the use of the ordinary
metallic tag or thin strip having its ends united by an impressed seal, and to
accomplish this without any material change in the parts and with the minimum
labor and expense.
Finally, it is my aim to improve the construction of the metallic tag; to effect
an economy in the use of the metal from which said tags are formed; to so combine
a record slip or card therewith as to prevent all possibility of the loss or premature
removal thereof and avoid the possibility of wearing or cutting the strip by the
edges of the metal.
The invention consists to these ends, in the novel features of construction and in
the parts and combinations of parts hereinafter fully described and then particularly
pointed out in the claims.
To enable others skilled in the art to fully understand and to make and use my
said invention I will now describe the same in detail, reference being had to the
accompanying drawings, in which:

Referring to Figures 1 to 6 of the drawings, I designates the base-plate of that
part of the lock which is rigidly attached to the car by means of bolts 2 or other
suitable means. This plate is provided in my invention with an integral projecting
plate 3, which enters the eye or loop formed in the end of the hasp 4, and has an
opening, preferably of rectangular forin, which receives the bolt by which the hasp
is confined thereon. At a short distance below the plate 3 is formed a projecting
boss or block 5 provided with a chamber of a size and shape corresponding
substantially with the opening of the plate 3. This chamber is formed in the
block 5 in such manner that its opening is upon the side adjacent to the plate 3.
The bolt which confines the hasp 4 consists of two parts or members 6 and 6ª.
The inner member 6 is provided with a nipple 7 projecting from its inner face near
one end, and seated in a recess in the corresponding portion of the outer member 6",
the two being connected by a spindle or bar 8 passed through an opening 9 in the
nipple and through a suitable opening in the other part of the bolt. This spindle
is of such length as to permit the nipple to be raised out of its seat far enough to
clear the flanges 10 upon the sides of the inner or rearward member 6, from the
rabbets 12 in the body of the other part whereby the face of the latter may be
exposed should this be necessary, either for repair or other purpose. The spindle
is provided with an eye 13 at one end to permit its attachment to a chain which is
secured to the car or car door, and its other end is upset so that the two parts of
the bolt cannot be entirely detached.
The bolt, when its two members are united, is practically a unit, its external
form and size being such that it will readily enter the opening in the plate 3 and
lie in front of the hasp, its lower end entering and substantially fitting the chamber
in the boss or block 5. From the exterior face of the outer member of the bolt
projects a portion 14 of greater thickness forming a shoulder which lies above and
rests upon the plate 3, in order to prevent the end of the bolt from being battered
by impact upon the bottom of the chamber in the block 5.
The space between the flanges 10 of the rearward member of the bolt is filled by
the solid body of the outer member 6, which is rabbeted along its edges to
receive said flanges. At the lower end of the rearward member is formed or
mounted a rib of metal 16 lying centrally and longitudinally and having any
suitable thickness by which channels 17 of equal width shall be left between it and
the flanges 10. At its upper or inner end this rib rises to the height of the flanges
or thereabout, and a little below this extremity the rib is cut away nearly to its
base, leaving a space 18 for a purpose presently to be described. The lower
portion of the rib is beveled off so that its upper edge approaches at the lower

page_text: extremity of the rib very near the face of the bolt from which it projects. From
its lower end therefore, the flat edge of the rib forms an angle with the face of the
bolt until it reaches the opening 18 where it terminates, the end of the rib being at
a right angle with the face of the bolt from which it projects. The square end of
the rib is provided on each side with a concave under-cut 19 by which a cutting
edge 20 is formed between the rectangular end of the rib and the face of the bolt.
A leaf spring 21 is secured by one end to the post 22, above the opening 18, said
spring crossing this opening and having its lower end overhanging the flat top of
the rib and pressing against its upper end, as seen in Fig. 3. The bolt being
inserted in the plate 3 and having its lower end lying in the chamber in the
block 5, a metallic tag 23 having a tongue 24 which is provided with a slot 25 is
applied by inserting the tongue 24 in a narrow aperture 26 formed in the block 5
and entering the chamber therein at such a point that the end of the tongue may
penetrate between the two members of the bolt in which space is provided for that
purpose. The end of the tongue rides upon the beveled Hat top of the rib, raises
the spring 23 and, as its slot 25 comes into position the rib enters the same and the
spring suaps the integral end of said tongue behind the end of the rib and into the
opening 18. Having reached this point it cannot be removed without rupturing
the tongue. The width of the aperture 26 in the block 5 is such as to permit the
entrance of the tongue 24 but prevents the insertion of any instrument by which
the spring 23 may be raised, and the strength of the latter and the construction and
position of the parts entirely preclude all possibility of removing the tag except by
rupturing it. When it becomes necessary to remove it, sufficient force is exerted
to cause the knife edge 20 to sever the end of the tongue.
The tag 23 is provided with a number, or character stamped or embossed therein
by which it is identified. A card 27 is attached by rolling the metal of the tag
over with and upon the paper, or card and seaming the whole by pressure. This
card is provided with space for all the Decessary sealing records, and its other side
may be used for the records usually made upon the side cards.
I make provision in this form of my invention in case of necessity for the use of
the ordinary impressed metallic seal, in connection with the wire, or flat metallic
band, heretofore commonly used, without modifying the invention in form, or
construction. To accomplish this I form in the upper end of the outer member of
the bolt, a kerf 28 of a width sufficient to admit the flat metallic band, and at the
outer edge of this kerf is formed an aperture 29 of a diameter greater than the
width of the kerf, to admit the wire strand should this be used. A similar kerf 30
and aperture 31 is formed in the plate 3 on each side of the opening receiving the
bolt. The manner of applying the wire is shown in dotted lines in Fig. 1, and the
use of the flat strip is so obvious as to require no explanation.
In embossing the proper number upon each metallic tag, I prefer to perforate
the metal in advance of and following the number, in order to prevent the
alteration of the latter by the addition of further figures.
I have shown these perforations in Fig. 6, as having the form of a cross, but
they may be of any suitable pattern, such as a star, a letter, a dash, a circle,
square or any other shape preferred. The numbers embossed upon the tags will
be consecutive and when issued the tags will be charged to the person, or
corporation receiving them. The sealing record, exceptions, and other entries, will
be made upon the slip, forming a permanent part of the metallic tag, and when the
latter is removed, as it will be at the destination noted upon the slip, the latter
will have a complete record showing the road and the initial, or name, of the person
to whom the tag was issued, and whose duty it was to seal the lock; the date,
train-number, consignor, consignee, the contents of the car sealed, the arrival at
destination, and the "exceptions."
The condition of the tag, also will show most conclusively whether the lock was
sealed since the tag cannot be removed without rapturing the tongue by exerting
such a degree of force thereon as to cause the knife-edge 20 to cut the end lying
in the opening 18 in the bolt, this cut being made by the knife-edge 20 at the end

page_text: of the rib which holds the tongue in the end of the bult. It will be seen from
examining the drawing that the removal of the tag in any other way is wholly
impossible, since no instrument can be inserted between the two parts of the bolt
which are wholly enclosed at the end, in the chamber in the block 5. The
aperture 26 in the latter will only admit the tongue of the tag, and should the
latter be cut by withdrawal, its reinsertion in such manner as to avoid detection
is impossible. The tags with their attached slips are filed away as part of the
permanent records of the road.
Referring to Figs. 7 to 13 of the drawings illustrating the modification of the
invention, 1, in said drawings, indicates the base-plate, or that part of the lock
which is permanently attached to the body of the car, or to the car-door, as the
case may be. From the outer face of this plate projects a staple 2b, having an
opening of such size as to readily receive the bolt of the seal-lock, which confines
the hasp 3 in place, when the door is locked, the end of the hasp having an
opening through which the staple plate passes.
At a suitable distance below the latter a rigid block or housing 4 projects from
the face of the base-plate a recess or chamber being formed in the side adjacent
to and parallel with the staple plate. This chamber is of substantially the same
size and shape as the opening in the staple-plate and of any depth suitable for
receiving and securely retaining the end of the locking bolt.
The bolt consists of two members or parts 5 and 6. The part 5b is provided
with a head 7b, having a flat lower face and is of such size and form that it may
seat and rest upon or cover the staple plate 2. Upon the lower face of the head 7
is a rigid hanger 8b, upon one face of which is a rib 9, of less width than the hanger
and of suitable thickness which increases somewhat as the lower end of the banger
is approached. The outer face of the rib 9b, thus converges toward the face of the
hanger, as it approaches the top of the latter, where it is curved toward the
opposite edge of the head 5%, forming thereby, a concave surface 10%. The edges
of the hanger are cut away at the lower end as seen in Fig. 11, so that the end of
the rib, which is here at its maximum thickness, extends below the sides of the
hanger. When the part 5 is cast in the mold, the lower end of the rib 9b, is
formed with an angular slot 12, which lies across its face and extends to and into
a nearly circular opening 13b, of somewhat greater diameter than the pivot-pin
which connects the hanger to the other part 6 of the bolt. The width of the
slot 12 is sufficient to admit the pivot piu which is formed in the manner presently
to be described.
The second part 6 of the bolt consists of a central plate 14b, between two
parallel side plates 15, the pivot pin 16", being cast between and as part of the
ends of said side plates which may be provided with ears 17", at their angles, for
this purpose. Upon the face of the plate which lies between the side plates is
formed a substantially triangular lug 18, having that edge or face which
corresponds to the hypothenuse of the triangle substantially parallel or nearly
parallel, when the two parts of the bolt are closed with the surface of the tongue 9b
in the part 5". The width of said tongue is such that it enters freely between the
side plates 15", and the square end 19, of the lug 18, which corresponds to the
perpendicular of the triangle, lies at a little distance from the end of the plate 14b.
At, or near, the point of intersection of the hypothenuse and base of the triangle
represented by the lug 18, pockets 20%, are formed in the face of the plate 14",
upon both sides of the lug, and at the ends of said pockets nearest the said point
of intersection they are terminated by walls 2.1, at right angles with the faces of
the plate in which they are formed though I may make this angle less than ninety
degrees, whereby the two walls of each pocket will be at a more acute angle.
The parts 5 and 6b, are united by merely slipping the pivot pin in the latter
through the slot 12b in the tongue 9%, until it reaches the opening 13. One or
more blows with a hammer upon the end of the tongue will then close the slot
and confine the pivot pin in its seat, the opening 13b being cast of such diameter as
10 permit the slot to be closed in this manner without binding the pin.

page_text: When the part 6b is turned into locking position it forms, in conjunction with
the hanger 8, a bolt of such size as to substantially fit the opening in the staple
plate 2, as well as the chamber in the housing into which its end descends.
In the bottom of the chamber last mentioned is formed a narrow slit 22b, of
such dimensions as to admit the thin strip or tongue of metal 23, which forms
part of the sealing tag 24. The slit 22 opens at a point coinciding with a
converging opening 25, between the rounded end of the rib 9b, and the beveled
end portion of the face of the plate 14b, as seen in Fig. 8. This opening directs
the end of the strip or tongue between the two parallel, or nearly parallel surfaces
of the rib 9, and the triangular lug 18, which are separated by a sufficient interval
to allow the strip to pass. After passing beyond the end of the lug 18, the end of
The strip impinges upon the concave surface 10 of the rib 9, which curves over
toward the face of the plate 14, from which the lug 18 projects. By pushing
the strip in as far as it is permitted to pass its end will be carried toward the
plate 14, and the lug 18 will enter a slot 26" in said strip which is of such length
that the greater portion of the length of the strip will be held upon the edge or
inclined face of the lug 18. This causes the strip to assume a comparatively sharp
curve as its end reaches the end of the concave face 10. This causes the metal
to assume and retain a curved shape, as seen in Fig. 8, thereby engaging the slotted
portion with the angular end of the rib causing it to retain said engagement by
the form imparted.
Between the slotted portion of the strip 23ª and the metallic tag :4, the edges
of the strip are cut or slit, transversely, the length of the slits 27° thus formed
being substantially equal to the width of the metal on each side of the slot 26º.
From the inner ends of these slits 27, the metal is slitted longitudinally by short
cuts 28, extending toward the free end of the strip and the short tongues 29", thus
formed are bent slightly rearward, as seen in Fig. 1. When the strip is inserted
as described, and when the desired curvature has been formed by its insertion a
slight retractile movement will cause the tongues 29 to pass into the puckets 20",
the ends of said tongues closely hugging the lowest points in said pockets. The
purpose of this construction is to provide an effectual and absolute safe-guard
against every possible method of picking the lock by the insertion of a thin
instrument capable of so far removing the curvature of the strip 23 as to enable
its slotted end to be drawn off the lug 18b. It will clearly he seen by Fig. 10 that
the insertion of such an instrument over the central part of the strip in line with
the slot 26 will be wholly ineffectual as it will merely pass over the end of the lug
and at some little distance from the curved portion. The insertion on either side
of the centre will inevitably cause the end of such an instrument to be caught by
the tongues 29 or between said tongues and the main body of the strip from which
they are struck. Further passage by an implement that can be devised is wholly
impossible and by this simple construction I provide a safe-guard against all
attempts at tampering with the lock which no skill or patience can overcome.
The metallic tag 24 of which the strip 23 forms part is composed of any
suitable sheet metal tin being preferred. Its dimensions and those of the strip 236
are so proportioned that a number of tags can be formed from a sheet of metal,
without any waste, this being a matter of some importance, in view of the great
number of tags used upon seal-locks. The body of the tag 24 will have embossed
thereon such matter as before explained, or as may be usual, or desirable, and
near its lower edge is formed an opening 30b, extending over somewhat less than
the width of the tag. This opening is formed in such manner that the edges of the
metal are turned or projected somewhat from the rearward face of the tag
resembling the burr formed by a punch. Through the opening 30º, is inserted a
slip of paper, or card-board 31° of suitable strength, the insertion being sufficient
to carry the end of the strip above the opening 30. The sheet metal is then
folded upon itself along the line of the opening 30", so as to enclose the inserted
end of the slip between two thicknesses of metal, as shown in Fig. 13. The edges

page_text: of the metal between which the slip lies are curled, or turned, far enough to prevent
wearing, or marring the slip when the latter is bent or folded, as shown at 32",
Fig. 13.
A series of openings 33b are then punched through both thicknesses of metal,
and through the interposed slip, the punch used being blunt or of such form that
one thickness of the metal will be drawn through the paper slip and through the
other thickness of metal, while the slip will also be drawn between the two portions
of metal which are turned by the action of the punch. The projecting edges
surrounding the openings 33" are then upset or riveted down by a tool similar to
that used in fastening an eyelet, as shown by the numeral 34, in Fig. 13. The
paper being caught between these upset marginal portions it cannot be removed nor
can the upset or riveted portions 34" be caused to release the slip without such
mutilation or marring as will afford ample evidence of the attempt.
The record slip 31" affords ample space for the sealing record, the name or the
letters or characters indicating the name of the road, the train number, date
consignor, consignee, contents of car sealed, the name or initial of the person to
whom the tag is issued, and who seals the car, the arrival at destination, and the
"exceptions."
I use I may and preferably do, form a shallow channel 35 in the outer face of
the plate 5, and an opening 30 in the head 7" registering with said channel. The
front angle of the housing 4 is also removed, as shown at 37", Fig. 8 sufficiently to
expose the lower end or portion of the channel 35. Through the latter and
through the opening 36" the metallic strip heretofore used may be inserted, its
ends being brought together just below the housing 4, and united by the metallic
impressed seal, as seen in dotted lines in Fig. 8. This construction is provided to
enable the lock to be used upon roads where the old form of tag and lead seal is
retained.
in use the bolt is attached to the staple holding the hasp by a chain, or connected
in any suitable manner to the car, so that when removed from the staple plate and
housing it may hang by the chain in convenient position for use. When detached
the parts 5 and 6 of the bolt assume the position shown in Fig. 9.
