AUTOMATIC LOCKING CAR SEAL Filed March 3, 1934 Patented Feb. 26, 1935 AUTOMATIC LOCKING CAR SEAL Richard Paul Krause, South Bend,: Ind.i Y X Application March 3,

Claims.

This invention aims to provide a novel means for sealing car doors, heaters, tanks, hampers and the like. The invention .aims to provide novel means whereby a wire of circular cross 5 section, either solid or twisted, may be used of devices of that type to: which the invention.

appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise. embodiment of the invention herein disclosed,

may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing:

Fig. 1 shows in plan, a device constructed in accordance with theinvention;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a section on the line 3--3 of Fig. 2;

Fig. 4 is a section on the line 4--4 of Fig. 1;

Fig. 51s a sectional view with parts in elevation, showing the slide partially in place.

In carrying out the invention, there is provided a case 1 of tubular form, the case preferably being made of metal. The case 1 is fashioned from a single strip of metal, bent upon itself to form a closed end 2 and an open end 3, and to form a. first side wall 4 and a second side wall 5, disposed opposite to each other. These walls 4 and 5 are trough-shaped, as Fig. 4 will show. They have transverse reenforcing ribs 6. Upon their longitudinal edges, the walls 4 and 5 of the case 1 are supplied with outstanding flanges, interlocked by bending, or connected otherwise, to form beads 7. The walls 4 and 5 are inclined toward each other, near to the closed end 2 of the case 1, so that the case, at its closed end, has a tapered portion 8. Located within the case 1 is a keeper 9. This keeper 9 is in the form of a tongue, joined integrally at. 10 with the outer end of the wall 5, as shown in Fig. 2. In the wall 5, a seat 11 is formed, in which the keeper 9 is received. The longitudinal edges of the seat 11 converge toward the outer or open end 3 of the case 1, as shown at 12, and the longitudinal edges of the iesijserial No. 713,914.

(01. 292-s1s) a keeper 9, marked by the numeral 14, are correspondingly inclined, the. keeper, therefore, fitting closely andctightly in the seat 11. The keeper 9 has a reduced end 15, located near to the closed end 2 of the; case 1. As shown at 16 in Fig. 2, the end of the keeper 9 is slightly inclined away from one of the parts that form the tapered portion 8 of the case 1. Intermediate its ends, the keeper 9 is supplied with an inwardly inclined tongue 17. a

The numeral 18 marks a slide,.preferably in the form of a strip of metal. At itsouter end,

TENTjOFFlCE the slide 18 has a hole 19 which may be used for various purposes, such as hanging up the article or carrying it; on a wire orring (not shown), The slide 18 has a first hole20, located in the longitudinal central line of the slide, and. slightly, nearer to the inner end of the slide than to the end ,of the slide which has the hole 19. An inclined resilient latch 21 is struck from the inner end of the slide 18. The slide 18 has a second hole 22 and a third hole 1 23,.spaced apart both longitudinally and transversely of the slide, and disposed between the hole 20 and the latch 21. The inner end of the slide 18 may be strengthened by a longitudinal rib 24, disposedbetween the holes'22 and 23.

The numeral 25 designates a link, in the form of a loop of wire, one end of which is hooked at 26 through the hole 23 in the slide 18.

In practical operation, one end of the link. 25 is hookedat .26 through the hole 22 of the slide 18. and one side portion of the link is threaded through the hole 20 of the slide. The slide 18 is inserted into the open end 3 of the case 1 and is pulled to the right in Fig. 5 until the latch 21 on the slide engages temporarily with the tongue 17 on the keeper 9. This stops the slide 18 in such a position that the hole 23 in the slide is just outside the open end 3 of the case ,1, the hole 22 being within the case, as shown in Fig. 5. The link 25 is extended through any article (not shown) which is to be sealed. The link 25 then is extended through the hole 20 of the slide 18, and the end of the link is hooked into the hole 23 of the slide.

The slide 18 is advanced into the case 1 until the end of the slide engages one wall of. the tapered portion 8 of the case 1, as shown in Fig. 1.

The resilient latch 21 of the slide 18 snaps into engagement with the end 15 of the keepers), and the slide is locked in the case 1, with both ends of the link 25 housed within the case. i

The reason for having the longitudinal edges 12 of the seat 11 in the case 1 converge toward the open end 3 of the case 1, and for having the correspondingly shaped longitudinal edges 14 of .the keeper 9, is to make it practically impossible to open the device by pulling on the link 25 or the slide 18 until the keeper unfolds outwardly in the direction of the arrow A in Fig. 3. So far as movement in the direction of the arrow A is concerned, the keeper 9 is wedged in the seat 11 of the case 1.

The device is simple in construction but will be found thoroughly efficient for the ends in view. It affords a simple means whereby a piece of wire or the like may be used to form the link 25, and when the parts are assembled as shown in Fig. 2, an opening of the seal is impossible unless the person opening it resorts to the destruction of the seal, in which event the opening will be manifest upon inspection.

Having thus described the invention, what is claimed is:

1. In a seal of the class described, a tubular case, one end of which is open, a slide insertible into the case, the slide being provided with an opening, a loop-shapedlink comprising side mem bers, the intermediate portions of which are extended through the opening of the slide, means for connecting the ends of the side members of the link with the slide, the ends of the side members of the link being housed within the case when the slide is advanced sufficiently into the case, and automatically-acting latch means on the slide and on the case for holding the slide advanced in the case, with the ends of the side members of the link housed within the case. i

2. In a seal of the class described, a tubular case, one end of which is open, a slide insertible into the open end of the case, and having holes near to its inner end, the slide being provided intermediate its ends with an opening, a loopshaped link comprising side members, the intermediate portions of the side members of the link being extended through the opening ofthe slide, and having hooks engaged in the holes of the slide, the hooks being housed within the case when the slide is advanced sufiiciently into the case, and automatically-acting latch means on the slide and on the case for holding the slide advanced in the case, with the hooks of the link housed within the case.

3. In a seal of the class described, a tubular case, one end of which is open, a slide insertible into the open end of the case, a loop-shaped link comprising side members, means for connecting the side members of the link with the slide, the ends of the side members of the link being housed within the case when the slide is advanced sufficiently into the case, and automatically-acting latch means for holding the slide advanced in the case, with the ends of the side members of the link housed within the case, said automaticallyacting latch means embodying a keeper extended into the case from the open end of the case, the slide having means for engaging the keeper, the case having a seat wherein the keeper fits, both the seat and the keeper being tapered toward the open end of the case, thereby to wedge the keeper in the seat and render it diflicult to pull the keeper outwardly through the open end of the case by pulling on the slide or the link.

4. In a seal of the class described, a tubular case, one end of which is open, the opposite end of the case having an inclined portion, a slide insertible into the open end ofthe case, a loopshaped link comprising side members, means for connecting the ends of the side members of the link with the slide, the ends of the side members of the link being housed within the case when the slide is advanced sufiiciently into the case, a keeper extended into the case'fromthe open end thereof, and interengaging elements on the keeper and on the slide, the slide engaging the said inclined portions of the case, to cause said elements to interengage, when the slide is advanced into the case.

5. In a device of the class described, a tubular case, a keeper extended into the case, the keeper having a terminal latch element, and an intermediate latch element, a slide insertible into the case and engageable with each latch element, the slide having longitudinally spaced second and third holes, a loopshaped link having its ends engaged in the second and third holes detachably, the second hole being housed inaccessibly within the case, and the third hole being without the case when the slide is engaged with the intermediate latch element, the second and third holes being within the case when the slide is engaged with the terminal latch element, the slide having a first hole which is without the case when the slide is engaged with the terminal latch element, the loop-shaped link comprising side portions, both of which are extended through the first hole of the slide.
