SEAL- SPECIFICATION forming part of Letters Patent No. 325,661, dated September 8, 1885. Application filed December 1 1834. (Modehl T all whom it may concern:

Be it known that I, JosEPH H. EDGAR, a citizen of the United States, residing at Ar gent-inc, in the county of \Vyandotte and State of Kansas, have invented certain new and useful Improvements in Seal Locks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which .it appertains to make and use the same, reference being had to the accompanying d rawings, forming a part of this specification.

My invent-ion has for its object a seal-lock for car-doors or other purposes in which the seal must first be broken in order to reach the locking devices and release the hasp, and wherein the seal may protect the opening to said devices and afford a better concealment thereof, and at the same time to afford a fastening which may be constructed inexpensively and will give additional security to the looking device; and it consists in the novel construction and combination of its several parts, hereinafter more fully described, and specifically pointed out in the claims.

In the drawings, Figure l is a front view of the seal-lock, showing portions of the cardoor and janib to which it isattached. Fig. 2 is a longitudinal sectional view taken through the sealing devices, as seen in Fig. 1, and show ing the mode of attachment of the latch to the staple. Fig. 3 is a side view of the keeper and the portion of the hasp which receives the seal. Fig. 4 is a sectional view of end of latch which enters the keeper. Fig. 5 is a front view of the seal-plate, showing the seal-h older and openings therein to receive the keeper and to permit the lifting of the latch.

A represents the seal-plate; a, the transverse opening in plate A to admit the keeper; a, the transverse opening in plate A to permit the lifting of the latch. a is a rim or projection on the scal-plateA, inclosingthe opening tothe latch, its sides holding the seal. a" a are perforations in the seal-plate A to receive the ends of the staple.

B is the hasp. b is the transverse opening in the hasp for exhibiting the seal. b is the keeper on the hasp. b is the slot in the keeper. I) is a recess in the hasp around opening b.

If 1s a longitudinal, transverse opening through the hasp to receive the staple. 15 is a longitudinal transverse opening through the hasp B, to receive the lag-screw.

C is the lag-screw.

D is the latch. (Z is the inclined portion of the latch which engages the keeper. (2 is a perforation in the end of the latch to receive the prong of the staple. d is a recess in under side of latch.

E is the staple. c c are the prongs of the staple.

G represents an ordinary glass seal.

H represents the door of a car H, the jamb.

In the construction of my invention I make a Hat plate, A, from suitable material, and of the proper length and width to receive the seal-holder and locking devices. I then make near one end of the seal-plate Athe trans 7o verse opening a, of a suitable size to receive the keeper 6 on the hasp B. At a suitable distance to one side of the opening a and toward the center of the said plate A, so as to come opposite the opening bin the hasp B 5 when the keeper 1) is in the opening a, I make the transverse opening (4., extending in length a suitable distance to operate the latch D.

In the seal-plate A, and in the end opposite to that having the slot at, and in a central relation to said plate A,I make the perforations a a said perforations being, preferably, in line horizontally, for the purpose hereinafter described. Through the perforations a. a, I introduce from the outside of the plate A the ends of the prongs c e of the staple E, which prongs extend into the door. The ends of the prongs e 0 may, however, be upset and a head formed upon said ends after theirintroduetion 0 through the plate A and through and under the latch, if desired, thereby preventing the withdrawal of the said staple. Ithen lnakea latch, D, from suitable material, to extend nearly the length of the plate A,and perforate 9 5 one end of said latch, as at d.

In the under portion of the latch D,extending from that portion of the said latch having the perforation d toward its free end, I make p'ortionately to the distance the perforation d is made through the latch from the lower end the recess (1 said recess having a depth prothereof. The latch D is then placed upon the inner side of the plate A, one prong e of the staple E, toward the end of the plate, entering the perforation d of the latch D and perforation a of seal-plate A, and affording a pivot for the same, and the opposite prong e of the said staple entering the opposite perforations, a, or the seal-plate and aiiordin g a rest for the latch,and extending across the recess d in the said latch. The said latch D is made to extend from its point of attachmenta suitable distance beyond the opening a in the seal-plate A, so as to engage with the slot 1) in the keeper 1; on hasp B when the said keeper is pushed in said opening a. The end portion of said latch I) which enters the slot 1) in the keeper 1), is slightly inclined at d from the upper to the lower portions of said side, which, upon entering the slotin the keeper,will bind against the sides ofthe slots sufficiently to prevent its displacement in the jolt of the car.

In the door H, and opposite the latch D, I make a suitable recess, 71 to receive aud'permit the play of the latch. I then make the hasp B of a suitable length to be attached to the jamb H of the car-door and extend across the face of the seal-plate A. The end of said hasp which is attached to said door-jamb is made with a longitudinaltransverse opening, b through which the loop of the lag-screw O is inserted, and by means of the said loop and the opening in the hasp b secured to the doorjamb in such a manner as to permit, to a cer tain extent, a longitudinal movement of the said hasp B, wherebyin the fastening and unfastening of the said look the keeper may be given sufiicient play, when the door is closed, to readily enter the slot in the said plate. I then make in the hasp B, opposite the staple E, a longitudinal transverse opening, b, so

' that when the keeper is pushed into the opening a in the seal-plate A the said staple will enter the said opening I) and project through a sufficient distance to enable a padlock or other device to be conveniently secured thereto.

Upon the opposite end of the hasp to that which is secured to the door-jamb I form the keeper b, which projects from said hasp in the direction of the seal-plate A. In the door H, opposite the opening a in the seal-plate A, I make a recess, h, which permits the entrance of the keeper 1).

For the purpose of receiving and holding the seal in place in the seal-plate A and preventing the introduction of any device between the hasp B and the seal-plate to dislodge the seal, I make the rim or projections a on the seal-plate A, extending around and at a suitable distance away from the opening a in the seal-plate A. Said rim a projects from the said plate A a distance proportionate to the thick ness of the seal. The hasp B is formed with a transverse opening, I), of a suitable size to exhibit the seal G, and a recess, 12 is formed in the said hasp, upon the inner side thereof, of the proper depth to receive the rim or projection a on the seal -plate A and extend around and inclose said rim.

In the operation of the sealing devices the seal-plate A is attached to a car-door by suitable nails or screws, and the hasp to the side of the car by the lag-screw 0, so as to bring the said hasp opposite the plate A and the locking insured. The seal of the common and well-known kind is then inserted in the recess 1) in the hasp B, and the keeper b, inserted in the slota, made to lift the latch, which latter falls into the notch or slot in said keeper, and as the motion of the car is increased the latch will be firmly held and wedged therein.

The advantage of my improved seal-lock is found in its entire simplicity of construction, all of its parts being so adjusted as to economize space and attain the most serviceable results. To release the hasp from the seal-lock the seal is first broken and the slot at exposed, through which a pin or any suitable device may be inserted and the latch raised from the keeper.

Having fully described my invention, what I now claim as new, and desire to secure by Letters Patent, is-

1. A seal-lock consisting of a plate having suitable transverse slots, and a seal-holder upon said plate adapted to receive a seal and cover a slot in said plate, and a hasp suitably inclosing said seal-holder and provided with a keeper and a latch, and a staple, one prong of which staple is adapted to serve as a pivot for said latch and the opposite prong as a lug for the latch to rest upon, as described.

2. The combination, with the seal plate provided with suitable transverse slots, and a seal-holder upon said plate adapted to receive a seal and inclose a slotin said plate, of ahasp IOC partially inclosing said seal-holder and provided with a keeper, and a latch pivotally attached to said seal-plate adapted to engage said keeper, and inclined as shown and described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
