lSEAL-LOCK.

SPECIFICATION forming part Of Letters :Patent N0.654,021, dated July 17, 1900. Application filed April 21, 1900.V Serial No. 13,727. (No model.)

To all whom t may concern:

Be it known that we, CHARLES ALPHAUS RAsoo and JOHN ToMLINsoN TAYLOR, citizens of the United States, and residents of Americus, in the county of Sumter and State of Georgia, have invented a new and Im proved Seal-Lock, of which the following is a full, clear, and exact description;

This invention relates to improvements in seal-'locks particularly adapted for use on freight-car doors; and the object is to provide a seal-lock of simple construction and comparatively cheap to manufacture and in which the sealmust be destroyed or broken before the lock' can be opened.

We will describe a seal-lock embodying our invention and then point out the novel features in the appended claims.

' Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a perspective View of a seal-lock embodying our invention. Fig. 2 is a front view with a portion of the front plate removed and showing the locking position of the parts. Fig. 3 is a similar view, but showing the parts in unlocked position. Fig. d is a section on the line 5c' a: of Fig. 2, and Fig. 5 is a section on the line g/ y of Fig. 2.

The lock comprises a casing 1, adapted to be secured to the outer sideof a car 2 adjacent to the sliding door 3. Mounted to swing in the casing is a hook-latch 4, having an arm 5 extended outward through an arc-shaped slot 6 in the front plate 7 of the casing, and extended upward from this arm 5 is a lug 8, provided with a recess 9, adapted to receive one end of the glass sea110. The said recess opens upward and outward so the seal may be slipped therein. Extended horizontally from the arm 5 is a perforated lug 11, adapted to receive the hasp 12 of a padlock, the said hasp also passing through a perforation in a lug 13, fixed to the outer side of the front plate 7. The hook-shaped latch el. is designed to engage with the `hook-shaped end 14 of a locking-bar 15, attached to the sliding door 3.

Mounted to swing on the outer side of the front plate 7 is a keeper-block 16, having a recess 17 in its end to receive an end of the pass into the recess 9.

,the upper edge of the seal.

seal 10, as plainly indicated in Fig. 2. Seated in a recess formed in the inner side of the keeper-block'l is aspring-pressed lug-18,`de signed to engage in a recess19,'formed inthe outer surface of the front plate 7 As will be noted in Fig. 5, the base-Wall of-this recess 19 is inclined downward and outward, so'that when the keeper-block is moved .in one direc-A tion it will cause the spring-pressed lug 18 to be moved inward.y 'l

In operation when the parts lof the lock in the casingv 1 are in the position indicated in Fig. 3 the door maybe moved to its closed position, which will pass the end of the bar 15 into the loekscasing, so that the hook-latch may be turned down into engagementthere` with, as indicated in Fig. 2. The seal 10 is to be inserted in the recess 17. Then by turning the keeper-block 16 to the position indicated in Fig. 2 the other end of the seal will The spring-pressed lug 18.will pass into the recess19 and prevent any possible upward movement of the keeper-block, and it cannotV be turned downward because of the seal 10 engaging in the recess, and particularly as the stop-block has a forward projection 2O for engaging upon Of course when the parts are thus placed the hasp 12 of the padlock is to be engaged with the lugs 11 and 13.

When it iswdesiredy to open the Adoor of the car, the seal 10 must be broken. Then after removing the padlock the hook-latch may be turned to the position indicated in Fig.'3, releasing the hook end ofthe bar 15. When it is desired to relock the car with a new seal, the keeper-block may be rotated, as before described.

From the above description it will be seen that this seal-lock is of very simple construction, having no parts liabletoget out of order, and the seals being made of glass are very cheap as compared with metaly or like seals. v

Having thus described our invention, we claim as new and desire to secure by Letters Patent-v 1. A seal-lock fora car, comprisinga casing, a hook-latch mounted to swing in the casing, a hook-bar designed to be attached to the latch mounted to swing therein, a part carried by a car-door for engaging with said latch, an arm extended outward from the latch through a slot in the casing, 2llg extended upward from said arm and havingarecess to receive an end of a seal, means for locking the latch in :its closed position, a keeper-block mounted to rotate on the casing and having a recess to receive an end of the seal, and a spring-pressed lug carried by said block and adapted to engage in a recess formed in the outer surface of the casing, substantially as specified.

3. A seal-lock, comprising a easing, a hooklatch mounted to swing in the casing, adevice adapted to be attached to a car-door for engaging with the hook-latch, an arm extended from said hook-latch through a slot in the front plate of the casing, a recessed lug eX- tended upward from said arm, a perforated lug extended horizontally from the arm, a perforated lug on the front plate of the casing for registering with the lug on the arm, a keeper-block mounted to. rotate, on the `.front vplate of the casing and having a recess to receive an end of a seal and also having a forward proJection to engage upon the upper edge of the seal, and means for locking said block from upward motion when engaged by the seal, substantially as specified.

4E. In `a seal-lock, a casing, a hook-latch mounted to swing in the casing and adapted to' engage a part carried by the sliding door of a car, a recessed lug carried by said latch,

a recessed keeper-block mounted to rotate ou the casing, and a glass seal adapted to engage with its ends in the recesses of the lug and block, substantially as specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
