EDWARD J. BROOKS, OF EAST ORANGE, NEW JERSEY, ASSIGNOR IO E. J. v BROOKS 85 OO., OF NEW YORK, N. Y.
SPECIFICATION forming part of Letters Patent No. 364,892, dated June 14, 1887. Application filcd May 2, 189i'. Serial No. 236,?148. (No model.)i
To all whom, it may concern,.-
Be it known that I, EDWARD J. BEooKs, a citizen of the United States, and a resident of East Orange, in the State of New Jersey, have invented a new and useful Improvement in Seal-Locks, ofwhich the following is a specification.
This invention relates to self-fastening seal- Y locks for the doors of railway freight-cars, and
primarily to that variety of these fastenings in which a loose pin 7 orb'olt coacts With an ordinary hasp and keeper and with a seal, the latterapplied to the pin or bolt so that it must be broken and detached before the pin or bolt can be Withdrawn to release the hasp.
-The present invention consists in certain novel combinations of parts, and in a peculiarly-constructed seal, formingpart of the device, as hereinafter set forth and claimed.
y A sheet of drawings accompanies this speciiication as partV thereof. Y
Figure 1 of these drawings is a front view of a pin or a bolt, as it is hereinafter termed, and its seal, together with an ordinary car-door hasp and staple or hasp and keeper, illustrating this invention. Fig. 2 is a top view of said bolt and seal. Fig. 3 represents a back view thereof, and Fig. 4 an edge or side View. Fig. 5 represents a vertical section of the bolt and seal, illustrating the fastening or sealing operation. Fig. Gis a side view of the same fastened or sealed. Fig. 7 represents a vertical section of the bolt provided with an `internal spring; and Figs. 8 and v9 are, re-
spectively,aface View and a horizontal section of modied seals.
Y Like letters of reference indicate corresponding parts in the several figures.
In carrying out thisinvention in the best way now known to me I employ a strong bolt, B, and a frangible seal, S,.in combination with an ordinary swinging hasp, H, attached to the car-door, and a fixed keeper, K, which may be an ordinary staple secured to the side ofthe carin a convenient position, said keeper receiving the hasp horizontally and the bolt outside thereof in vertical position, as seen in Figs. 1, 5,-and 6, while said seal is applied to the lower end of the bolt, as represented in Fig. 6 and in dotted lines in Figs. l, 3, 4, and 5, so as to prevent its withdrawal 'to release the hasp until the seal is broken. For clearness the parts will be hereinafter described as occupying the relative positions above indicated.
The bolt B is preferably of T shapein front view, as represented in Fig. 1 and round in cross-section; and its head 7L is provided with a perforated lug, l', to coact with an attaching-chain and with another such lug, Z2, at one end,rto coact with the shackle of an ordi nary leadandwire seal, for example, passed therethrough and through the slot of the hasp on roads which employ such seals, and it is so shaped throughout as to be mainly formed in molds out of cast-iron; but these and like details are not considered essential to the respective features of my invention, as herein after claimed.
Said bolt B, for the purposes of this invention, is constructed with a recess or recesses, 71 inits exterior, near its lower end, preferably in the form of a pair of lateral notches, which are horizontal, or substantially horizontal, as seen in Fig. 4, and the inner walls of which are parallel, or substantially parallel, and it has a shouldered longitudinal bore, b, the
.larger upper end of which is securely plugged,
as represented at p, Fig. 6, While its contracted lower end extends through the eX-l tremity of the bolt. A headed locking-pin, l,
slides freely within said bore, and is normally projected by gravity at the lower end of the bolt, as seen in Figs. 1 and 4, in dotted lines in Fig. 5, and through the seal S in Fig. 6.
Primarily to protect the'projecting pin Z, when the fastening is not sealed, said lower end of the bolt B is further` provided with a rigid guard, g, which projects endwise behind the pin, as seen in Figs. 1, 3, 4, 5, and 6, and the face of said guard is provided with a Vlongitudinal guiding-concavity, g', and a terminal gage-hole, h', extends through its up` per end.
The seal S has rigid interlocking portions matching said recesses r in the bolt, a vertical socket, s, matching said lockingpin Z, and a l Vrigid finger-like projection, f, on its back matching said guiding-concavity g' and hole h.
In sealing the fastening, as illustrated by Fig. 5, said finger-like projection f is engaged with the guiding-concavity'g at the lower end front ofthe seal, as seen in Fig. 1.
posite said hole h in the guard g, and the seal is now moved horizontally7 backward, as rep resented by arrow 2. This carries said interlocking portions t' int-o said recesses r, and at the same time brings said socket s into line with the locking-pin l, which thereupon drops into the socket and securely fastens the seal in place.
The fastened seal is represented by dotted lines in Figs. 1, 3, 4, and 5, as aforesaid, and is more fully shown by Fig. G. The seal be ing, as it preferably is, of transparent glass, the `lockingpin Z is exposed to view within it, as indicated in the latter ligure. The pin is still more clearly seen from the front of the seal, as indicated by the exposure of the socket s in the full-line face view of the seal in Fig. 1. The condition of the seal is thus rendered manifest and thorough inspection facilitated. If preferred, the body of the seal may be opaque, as of brittle metal, pottery, or the like; butin this case a Window, fw, Fig. 9, should be provided to form altransparent portion in front of the locking-pin socket s.
The preferred transparent seal shown in Figs. 1 to 6 is furthermore constructed with recesses r r2 in its back, Fig.- 3, on the respective sides of the central portion in which said socket s is formed, and within these recesses distinguishinglabels d d2 are cemented, so that their faces are exposed to view at the The seal is thus readily provided with different origin or destination marks, and with serial numbers or the like, as illustrated by said labels d and di, respectively. Said labels may be of .paper or other fabric, and secured against Adistinguish the seals of different roads, as indicated.
After the seal is fastened in place, as illustiated by Fig. 6, tbc., as aforesaid, the locking-pin l cannot be retracted until the seal is broken, except by inverting the car; and the fastening may, if preferred, be readily rendered secure against being so unlocked by the ditching of a car by simply providing said bore bof the `bolt with alight spiral spring, s',
Fig. 7, of sufficient resistance to overcome the weight and inertia ofthe inverted locking-pin. So provided with a spring, the bolt will work in horizontal or inclined position, as well as in vertical position. To coact with the bolt I3, whether provided with a spring or not, apair of coinciding keepers, such as staples, upon the car side and door, respectively,'arc considered equivalents of a hasp and keeper.
To unfasten a car-door secured by the withindescribed fastening, the frangible seal S is knocked off downward, which breaks off said interlocking portions fi, and throws the seal clear of the locking-pin Z. The bolt Bis then withdrawn, which permits the hasp Hto be disengaged from the keeper K.
To prevent successful tampering with the sealed fastening, the body of the seal is extended upward so as to mask the opening at the lower end of the body of the boli-, as best seen at fm in Figs. 5 and 6. The bottom and lateral edges are provided with rearwardlyprojecting flanges f', so as to coact with said guard g for this purpose. VThe socket s is made sufficiently large and deep to prevent retraeting the locking-pin by concussion; and the lockingpin l may be made of brass to prevent moving itA by a magnet. A bushing, Z1', Fig. 7, at the lower end of the bolt may take the place of said plug p, .so as to be secured by the seal; and said gagehole h in the guard g may be made in the form ol' a closed socket, as shown in the same figure, should the bolt and seal be so used as to expose their backs. Other like guards and modifications will suggest themselves to those skilled in the art.
Having thus described my said improvement in seal-locks, I claim as my invention and dcsire to patent under this specification- 1. In a seal-lock, the combination, with a hasp and a keeper, of a bolt having a recess or recesses in its exterior near one end and a longitudinal bore, and provided with a lockingpin which slides within said bore and normally projects at said end of the bolt, and a frangible seal having a rigid portion or portions to engage with said recesses and a socket to receive said pin, substantially as herein specified.
2. The combination, with a hasp and a keeper, of a vertical bolt having a horizontal recess or recesses in its exterior near its lower end and a longitudinal bore, and provided with a locking-pin which slides loosely within saidbore and is normallyprojeeted at said lower end of the bolt by gravity, and a frangible seal having a rigid portion or portions to engage with said recesses and a vertical socket to reeeivc said pin, substantially as hereinspecified.
3. The combination, with a hasp and a keeper, of a bolt having a recess or recesses in its exterior near one end and a longitudinal bore, and provided with a locking-pin which normally projects at said end of the bolt, and a frangible seal having a rigid portion or portions to engage with said recesses, a socket to receive said pin, and a projection on-its back by which to retract said pin in sealing the fastening, substantially as herein specified.
4.. In combination with a frangible seal hav- IOO IIO
p having a recess or recesses in its exterior near one end to receive said interlocking portions, a longitudinal bore, a locking-pin which normally projects at said end of the bolt, and a rigid guard which projects endvvise behind the projecting pin and is provided with a-concave face and a terminal hole to coact with said projection in sealing the fastening, substantially as herein specified.
. 6. In combination with a bolt having a recess or recesses in its exterior near one end, a longitudinal bore and a locking-pin which normally projects at said end of the bolt, a frangible seal having a rigid portion or portions to interlock with said recesses, a socket which receives the projecting portion of said lockingpin, and a transparent portion which exposes the latter to view Within the fastened seal, substantially as herein specified.
