EXTENSION HASP.

Application filed January 10, 1922. Serial No. 528,336.

To all whom it may concern: 1

Be it known that I, EDGAR A. HILL,'a citizen of the United States, and resident of La Fayette, in the county of Tippecanoe and t y-State of Indiana, have invented certain new and useful Improvements in Extension Hasps, of which the following is a specification.

My invention consists in the provision of an extension hasp for use in conjunction with closure fasteners whereby a closure such as a car door may be secured in slightly open position to provide ventilation for the car.

It is well known that freight cars carrying perishable freight must be ventilated, and in order to accomplish this purpose it is the present practice to nail cleats across the doors to hold them. partly open, but this is unsatisfactory because the doors cannot be secured in a practical and yet substantial manner, and moreover, by such means they cannot be sealed.

My invention does not contemplate eliminating or modifying the present standard type of car door fastener in any particular, but consists of a simple and inexpensive device adapted to be quickly and easily removably attached to a standard fastener without changing the mode of operation of the latter, and which is capable of being sealed in the usual manner.

VVith-the foregoing and other purposes in view, my invention consists in the features of novelty to be hereinafter more particularly described in connection with the accompanying drawings, in which Fig. 1 is an elevation of a standard type of car door fastener with which the device of my invention is particularly intended for use.

Fig. 2, a view similar to Fig; 1 showing the device of my invention operatively associated with the fastener illustrated in Fig. l for holding a door partially open; and

Fig. 3, a perspective of my extension hasp.

Referring to the drawings in detail, ticularly Fig. 3, it will be observed that my extension hasp consists of a somewhat elonto gatedmember having an elongated slot 11 formed therein near one end and carrying near its opposite end a laterally disposed substantially T-shaped extension 12. The longer axis of the slot 11 is as shown disposed parallel to the longer axis of the mempar- 1 ber 10 and the head 12 of the extension 12 is disposed at right angles to thelonger axis of both the slot and member, whereby its accidental or surreptitious removal from operatlve association with the standard fastener illustrated in Fig. 1 is prevented,

as will hereinafter become more fully apparent.

The standard fastener illustrated in Fig. 1 consists essentially of a hasp 13, usually carried by the door 14;,and a keeper 15 therefor, usually carried by the car body 16. The hasp 13 is slotted near its two ends and has permanently engaged with one of its slots a door carried member 17 which serves to anchor the hasp to the door for swinging movement with respect thereto. The other slot, that is, the one in the free end of the hasp is adapted to receive a hi 18 on the keeper 15 when the door. is entirely closed and may be locked against removal from the lug by a swinging and: sliding pin 19 carried by the keeper and engageable through an aperture in said lug outwardly of the hasp- The fastener shown in Fig. 1 is entirely old and well known, but as is apparent is only capable of securing the door in entirely closed position. My extension hasp on the other hand is adapted for operative association with the fastener illustratedin Fig. 1 without alteration theretoin any particular and is capable of securing the door partly open, as shown in Fig. 2.

To obtain the assembled relation illus- I trated in Fig. 2, the member 10 is first positioned with its long axis at right angles to the long axis of the ha'sp 13 and the head 12 of the extension 12 is inserted through the slot in the free end of said hasp, after which the member 10 is rotated until its longer axis is alined with the longer axis of the hasp 13 4 when the hasp and member are secured together against separation and in effect constitute a hasp similar'in every respect to the hasp 13 except that it is longer and the door must therefore be opened a distance corresponding substantially to the length of the member in order to permit the slot 11 therein to be engaged over the lug 17 When the member 10 is secured to the hasp'13 in the manner indicated, it may then be secured to the keeper'in'the same .way that hasp 13 is secured thereto, and whenever desired, may be quickly and easily removed from the hasp 13 by simply rotating it until the head 12 is free to pass through the slot in the hasp.

To seal either the hasp 13 or the extension hasp 10 with respect to the keeper, the wire of an ordinary car body seal may be engaged in the usual manner with the lug 18 and pin 19.

From the foregoing description, taken in connection with the accompanying drawings, it is believed that the construction and utility of my invention will be fully understoodand while I have herein shown and described one specific type of extension hasp it is to be understood that my invention is not limited thereto except for such limitation as may be contained in the appended claims.

I claim 1. An extension hasp for closure fasteners comprising a member providedat one end with means for detachable interlocking engagement with a hasp element of an applied hasp fastener by application through the keeper receiving slot of the element and provided at its other end with a slot for receivmaasac 4 ing the keeper element of such applied hasp fastener.

2. An extension hasp for closure fasteners comprising a member provided: at one end with an angularly disposed extension for detachable interlocking engagement with a hasp element of an applied hasp fastener by application through the keeper receiving slot of the element, and provided at its other end with a slot for receiving the keeper element of suc'h applied hasp fastener.

3. An extension hasp for closure fastener.

comprising a member provided near one end with T-shaped lateral extension for detachable interlocking engagement with a hasp element of an applied hasp fastener by application through the keeper receiving slot of the element; and provided at its other end with a slot having its long axis extending longitudinally of the member and at right angles to the head of said T-shaped extension.

In testimony whereof ll hereunto afiix my signature.

EDGAR A. HILL.
