Application November 19, 1935, Serial No. 50,595

In Canada 2 Claims.

This invention relates to a shipping case fastener. Its primary object is to devise and construct a fastening device for shipping cases such as egg crates and the like which may be readily unfastened at the point of delivery without the use of key or similar method.

A further object of the invention is to provide a shipping case fastener that may be built into the case structure to detachably secure the lid to the case without the use of nails, screws, etc.

A still further object of the invention is to construct a fastening device to be associated with a shipping case to permit the lid being secured thereon and removed therefrom without damage to either lid or case so that the same may be used as often as required.

With these and other objects in view that may appear while the description proceeds, the invention consists in the novel construction and arrangement of parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawing, forming part of this application and in which:-

Fig. 1 is an end elevation partially in section of the fastening device associated with the lid and the keeper therefor associated with the case.

Fig. 2 is a cross-section View of the invention showing the fastener and keeper separated from each other.

Fig. 3 is a similar cross-section view showing the fastener in engagement with the keeper.

Referring more in detail to the drawing in which similar reference characters designate corresponding parts throughout the several views it will be seen the invention comprises a fastener unit l0 to be secured to the lid or cover structure H and a keeper unit 12 to be secured to the case structure I3.

The fastener unit comprises an elongated rectangular casing l4 having its ends l5 open to receive the ends of the cleats I6 w ich form part of the lid structure. In the iddle portion two spring wells [7 are for ed and positioned vertically therein. Thesaid wells are spaced equidistant from the center, being constructed with open slots I8 on the inner sides thereof and springs 59 are provided therein. A movable element which constitutes the catch member is located between th said spring wells and arranged for vertical mo ement. Said element consists of an inverted U shaped member 20 having an upturned hook or catch 2| formed on one edge thereof while the other edge 22 is slightly bent inward to form a guide. Ex-

June 18, 1935 tending laterally from the member 20 are two spring engaging arms 23 which rest on the upper end of the springs l9 and are designed to slide vertically in the slots E8 of the spring Wells I1. On the inside of the member 20 is a lug 24 by means of which the said member is manipulated while directly opposite thereto is an aperture 25 in the opposite wall of the member 20. Directly below this member is an aperture 26 in the bottom of the casing i4 through which the member 20 is projected. Another aperture 2'! is provided in the side wall thereof to permit an actuating tool 28 being inserted into the device as hereinafter described.

The keeper unit I2 comprises an elongated rec tangular casing having its ends open for the insertion of cleats 29. Said cleats extend therein to within a prescribed distance from the center leaving a space 30 therebetween. In the top of the unit is an aperture 3|, through which the member 26 projects while in the bottom thereof is a smaller aperture 32 to permit any dirt or other substance being removed therefrom. On the inside wall of the casing is an inwardly and downwardly turned flange 33, which is arranged to register with and to be engaged by the hook or catch 2|.

From the foregoing it will be seen that the two units are secured to or built into their respective members of a shipping case and arranged to register correctly when the said members are brought together for fastening. An actuating tool such as a screwdriver or any other similar medium is then inserted into the fastener unit through the

apertures

25 and 27 to engage the lug 24. The member 20 is then pushed downward, against the force of the springs which are thereby compressed, and projects through the

apertures

26 and 3! into the keeper unit I 2, until the hook or catch 2| engages the flange 33 where it is held by the spring tension.

To release the fastener the tool is inserted as before to engage the lug 2 3, then the same is depressed and pried slightly, moving the catch out of engagement with the flange. The member 20 is then permitted to withdraw, by means of the spring pressure into the casing I 4 and the lid is thereby released from the case.

It is believed that the construction and advantages of the structure is apparent from the foregoing paragraphs taken in conjunction with the accompanying drawing without further detailed description.

While the preferred embodiment of the device has been disclosed it is understood that minor changes in the construction and arrangement of parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

I claim:

1. In a shipping case fastener as described comprising a keeper element consisting of a casing having an aperture therein and a flange bent inwardly from the inner wall thereof, a fastener element consisting of a casing, a projectable catch member reciprocally mounted in said fastener casing, a spring associated with said catch member adapted to exert a retractive force thereon, 'a hook formed on said catch member, a lug associated with said catch member, said fastener casing and catch member having apertures through which a tool may be inserted to engage said lug whereby said catch member may be manually projected through the aperture of the keeper casing to engage said hook with the flange in the keeper casing.

2. In a shipping case fastener as described comprising a keeper element consisting of 2, casing having an aperture therein and a flange bent inwardly from the inner wall thereof, a fastener element consisting of a casing, an inverted U-shaped catch member reciprocally mounted in said fastener casing having laterally extending arms at its upper end, springs disposed beneath 10 said arms exerting an upward force thereon, said catch member having a hook formed on its lower inner end, and means whereby said catch member may be manually projected through the aperture of the keeper casing to engage the hook of 15 said catch member with the flange of said keeper casing.
