FASTENER.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed August 12, 1912. Serial No. 714,658.

To all whom it may concern:

le it known that 1, Mrs. J ENNIE VVnsoN, a citizen of the United States, residing at Earl Grey, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Fastenors, of which the following is a. specification, reference being had to the accompanying drawings.

This invention relates to an improved fa stener, and has for its primary object to provide a device of this character permanently attached to the part to be fastened, and which will effectively operate to positively hold said part in posit-ion with respect to the object to which it is attached against casual movement with respect thereto, but will admit of the quick and easy detachment of such part. when desired.

Another object of the invention is to provide an improved form of spring fastener particularly designed for use in attaching a milk strainer to a pail. the release of the catch when it is desired to remove the strainer effecting an initial upward and outward movement of the strainer and overcoming the friction thereof againstthe pail walls, whereby the strainer may be removedwithout necessitating the contact with the fingers therewith, thus avoiding liability of contamination.

Still another objectof the invention resides in the provision of a device for the above purpose which is extremely simple and inexpensive in construction. highly convenient and reliable in use.

\Vith the above and other objects in view, this invention consists of the novel details of construction. combination and arrangement. of parts as will be hereinafter more fully described. claimed. and particularly pointed out in the accompanying drawings,

in which Figure l is a plan view showing my im- 45 proved fastener applied to a milk strainer.

Fig. 2 is an enlarged detail section showing the manner in which the spring fastener engages upon the bea ded edge of the pail;

Fig. 3 is a detail fragmentary side elevation of the strainer removed from the pail showing the normal condition of one of the fasteners carried thereby, and Fig. 4 is a similar view of the strainer applied to the pail.

Referring in detail to the drawing, 5 designates a sheet metal pail which is provided with the usual beaded edge 6 at its open end.

The strainer, indicated by the numeral 7, lncludes an annular rim 8 of tin or other sheet metal, to one edge of which a w1re strainer cloth or screen 9 is secured in any approved manner.

Upon the rim 8, at diametrically opposite points. the spring fasteners 10 are secured.

Each of the fasteners 10 consists of a single length of resilient wire, the ends of which are flattened and secured upon the inner surface of the rim 8. This wire, adjacent its spaced ends, is bent outwardly over the edge of the rim 8, as shown at 11, and then extended inwardly and upwardly to provide the oonvergently disposed inclined portions.

12. From these inclined portions of the wire, the intermediate portion thereof is projected outwardly and curved, as shown at 13. for engagement over the rounded beaded edge 6 of the pail. The bight portion of this intermediate loop is reversely bent or outwardly extended, as shown at 1-1. to provide a suitable finger piece for a purpose which will be obvious.

In the use of the milk strainer, the rim 8 is inserted within the upper open end of the nail and is disposed against the inner surface of the body wall thereof. Upon pressing downwardly upon the edge of the rim 8. the intermediate loops 13 of the fasteners 10 will be forced outwardly over the beaded edge 6 of the pail. and the upwardly in clined portions 12 of the wire fasteners are drawn downwardly into close contact with the surface of said head. The tendency of these inclined portions 12 of the fasteners to return to their normal elevated positions causes the curved portion 13 of the loop to engage closely with the bead 6 and retain its position thereon. By the provision of these inclined portions 12 of the fasteners, the rim 8 of the strainer is also held closely againstthe wall of the pail. Thus, liability of the accidental displacement or the entire removal of the strainer is avoided. At the same time however, the strainer can be easily and quickly removed by simply engaging the finger pieces 14 of the fasteners and forcing the same. outwardly. The portions 12 ofthe fasteners assist in the release of the loops 13 from engagement with the head 6 and the upward spring of these fasteners tends to loosen the rim of the strainer 7 from contact with the wall of the pail, so that it is not necessary to engage the strainer with the fingers, the removal of the same be ing completed by simply graspin the fasteners 10 at opposite sides thereo and lifting the strainer off of the edge of the pail.

From the foregoing it is believed that the construction and many advantages of my improved fastener will be fully understood.

As the catches are each formed from a single piece of wire, it will be obvious that the same can be produced at a very small cost.

While I have shown and described the preferred construction of my invention, it is to be understood that the invention is susceptible of considerable modification without departing from the essential features or sacrificing any of the advantages thereof.

What I claim is The combination with an object and an element to be supported thereby, of a retaining clip produced. from a single strand of resilient wire and having its terminal portions parallel with the extremities thereof flattened, such flattened portions being perforated, anchoring means extending throug the perforations to secure the clip to the e e- Inent, said wire having connected bowed portions to form an intermediate expansi; ble loop and adapted to bridge an end portion of the object, the connection between such bowed portions being reversely bent to constitute a finger piece, said wire imme diately above the element being inclined downwardly in opposite directions toward the parallel terminal portions and being capable of fiexure relativelfi thereto.

In testimony whereof I ereunto afiix my signature in the presence of two witnesses.

Mrs. JENNIE WILSON.
