RICHARD P. WHITE; OF CHICAGO, ILLINOIS.

FASTENING DEVICE.

Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed December 23, 1918. Serial No. 267,923.

To all whom it may concern:

Be it known that I-, RICHARD P. WHITE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fastening Devices, of which the following is a specification.

This invention relates to improvements in fastening devices and more particularly to a fastener or clamp for clamping or securing the lid or cover to a receptacle.

One of the objects of this invention is the provision of such a fastener for clamping down the cover of a jar or crock or similar receptacle, so that the same is securely held and may be readily released, the fastener being particularly adapted for use in connection with the receptacle made of earthen ware or vitreous material or glass or similar substance. 7

A further object of this invention is to provide such a fastener for securely clamping and holding the cover in position in a yielding or resilient manner.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consistsin the construction, combination and arrangement of parts hereinafter described and then sought to be. defined in the appended claims, reference being had to the accompanying drawing forming a part hereof and which shows, merely for the purpose of illustrative disclosure, a preferred embodiment and also a modification, it being expressly understood, however, that various changes may be made in practice within the scope of the claims without digressing from my inventive idea.

In the drawings Figure 1 represents a side elevation of a receptacle supplied with a plurality of fasteners constructed to embody my invention, the fasteners to the right and in the middle being shown in clamping or fastening position and the fastener to the left being shown in release position. 7

Fig. 2 is a perspective view of the fastener illustrated in Fig. 1.

Fig. 3 is a perspective view of a slight modification of the fastening means, the parts being shown in the position assumed when in clamping or fastening position.

3a detail of o e of the fa te el men s i mouths, presenting a substantially unbroken interior surface and having a flat cover which is to be resiliently held in place on the mouth of said receptacle. This is most efliclently accomplished by resilient or yielding means and this feature is embodied in the construction of a fastening means according to my invention.

In Fig. 1 the numeral 1 designates the upper part of a crock or other receptacle which has a substantially straight inner surface and is provided with the peripheral head or enlargement 2, on top of which the cover or lid 3 is adapted to rest and be clamped. This cover or lid 3 is provided with an annular groove or recess 1 which preferably extends entirely therearound near the edge thereof, as best shown in Fig. 5. I also provide a plurality of lugs or projections 5 at various positions around the upper part of the crock or receptacle which lugs or projections 5 are each provided with a suitable horizontal passage or aperture to receive parts of the fastening means hereinafter referred to.

The preferred form of fastener or clamp is illustrated in Fig. 2 of the drawing and shown applied in use in difierent posltions in Fig. 1 of the drawings. It includes generally the clamping member proper 6 and the finger actuating member or lever 7. This finger actuating member 7 is in the general form of a loop, as shown, and bent at each side near the top end thereof to provide the loops 8. The free ends of the member are bent at right angles toward each other, as

indicated at 9. It is these free end portions which are positioned in the opening or aperture through the lug.5, whereby the fastener or clamp is attached in proper position to the crock or receptacle. It is to be noted that this finger actuating member is I bent at an intermediate point, as at 10, so

that the lower end part thereof extends away from the side of the crock or receptacle in a position convenient for manipulation.

The clamp or fastening member proper 6 is also in the form of a loop, having its free ends bent around the reduced part of the l ps or eyes 8, as at 11.. The legs of tlus clamping or fastener member diverge downwardly, as clearly shown in connection'with the central fastener shown in Fig. 1, of the drawing. The upper part of this clamping member is curved over, as at 12, and has a substantially straight engaging bar 13 which actually forms the end of the loop. This curved endpal't 12 is adapted to fit over the edge of the crock or receptacle and also the edge of the cover-therefor sothat the straight arm or bar 13 will engage the groove or recess in the cover or lid.

The parts are preferably made of wire or similar suitableresilient material, because it is essential that the clamp or fastener should have a resilient or holding action on the parts.

In operating the fastener the clamping member '6 is moved into engagement with the groove, as shown to the right in Fig. 1, at which time the loop 8 is in substantially the same horizontal plane as the free end 9 of the finger actuating member, or in other words,.this fin er actuating member extends in a substantia ly'horizontaldirection, when the clamping member engages the cover and before the parts are moved to "locking or clamping position. The Q erator then presses down on the same, the everage'causing a. considerable strain on the clamping or fastening member 6 so that it gives or yields slightly, due tothe resilient nature of the -material of which it is made and therefore holds a cover or lid on top of the receptacle in a resilient or yielding manner. At the end of the "fastening or clamping movement the loops or eyes 8 are within a line drawn through the point of bearing of the bar 13 on the top of the cover and the connection of the free ends 9 with the stud '5 so that the parts are securely locked againstaccidental release. As a matter of fact this part forms a toggle connection and moving the ber' proper,:18. The parts are otherwise of the same construction and operate in the same manner, as previously described.

It is to be noted that due to the diverging position of the arms of the clamping member thatwhen the clamp or clasp is in clampedfposition, an inward pressure will be exerted against the sides of the finger actuating member, tending tohold the free ends 9. and 1,5, in theinproper position in the aperture or passage within the stud'or projection '5 on the side of the crock, 'jar or other receptacle. The curve or bend 12 in the clamping member is sufiicient to provide for variation in the size and fit of the cover or lid on the receptacle.
