FASTENER FOR CAN-CLOSURES.

Specification of Letters Patent.

Patented May 22, 191 '7 Application filed April 23, 1915. Serial No. 23,399.

To all whom it may concern:

Be it known that I, JOHN W. BURGESS,

a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Fasteners for Can- Closures; and I do hereby declare the folarrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a fragmental perspective view of a milk can, showing the application thereto of the improved closure.

Fig. 2 represents a top plan view of the closure applied to use.

Fig. 8 represents a central sectional view through the upper portion of the can closure, and

Fig. 4: represents a fragmental sectional view on the line H of Fig. 3. I

Referring to the drawing in detail, wherein similar reference numerals indicate corresponding parts throughout the several views, the numeral 5 indicates the body of a milk can of the usual construction having the neck 6 and flared mouth 7 the latter being provided with the outwardly directed flange 8. The closure is designated generally by the numeral 9 and is formed with an upstanding flange 10 shaped conformably with the neck and mouth of the can 5 and having the edge lldirected outwardly overlying the flange 8. A. strap or handle 12 substantially U-shaped in cross section, as clearly illustrated in Fig. 1, is disposed diametrically of the closure 9 and the upwardly directed ends 13 thereof are secured by rivets or bolts 14 to the upstanding flange 10 of the closure.

The strap 12 is provided with a central aperture in which is vertically slidable a rod 15 carrying plates 16 and 17 at its upper and lower extremities, respectively. The rod 15 is reduced in diameter as indicated at 18 at its upper end to define an annular shoulder upon which is snugly fitted a bow spring 19 having the opposite ends thereof curved upwardly and having a central aperture snugly receiving the reduced end 18. A pair of locking bars 20 are pivotally secured by pins 21 to the ends of the plate 16 and are normally retained in alinement with the plate 16 by the tension of the bow spring 19, which has its opposite upturned ends positioned within notches formed in the undersides of the bars 20. The reduced end 18 of the rod is also screwthreaded to receive a nut 18, whereby the plate 16 is secured in position thereon.

The bars 20 are slidable through apertures 22 formed in the upwardly directed ends 13 of the strap 12 and in the flange 10 of the closure 9 and are adapted, when the closure 9 is properly seated, to project into recesses 23 formed in the inner surface of the neck 6 of the can to lock the closure against accidental removal. If it is desired to remove the closure 9, the rod 15 and plate 16 carried thereby are lifted by an upward pull upon the handle plate 17, thus withdrawing 6 and permitting the closure to be removed. As the rod 15 is lifted, the medial portion of the bow spring 19 is elevated while the free ends thereof are retained substantially in normal position and thus the spring exerts pressure tending to lower the plate 16 and extend the lockingv bars 20 outwardly through the openings 18 in the cap and flange 10. It will be clearly evident that the strap 12 also serves as an adequate handle whereby the closure may be removed with ease.

What I claim is:

1. A fastener for a can closure, a U-shaped strap secured diametrically of said closure, a rod slidable through centrally of said strap, a pair of locking bars pivotally connected with said rod, and means connected centrally with the rod and engaging said locking bars for normally retaining said locking bars in extended position.

2. A fastener for a can closure, a Ushaped strap secured diametrically of said closure, a rod slidable centrally through of said strap, a pair of locking bars pirotally connected to said rod, and a bow spring arranged centrally on said rod and interposed between said strap and said locking bars for normally retaining the latter in extended position within said recesses.

3. A fastener for a can closure, a U-shaped strap secured dian'ietrically of said closure and having a central aperture, a rod slidahle in said aperture and having a shoulder adjacent its upper end a pair of locking bars pivotally connecting with said rod, and a how spring arranged centrally on said rod and resting upon said shoulder and engaging opposite ends with said locking bars, to 15 normally extend the same.

In testimony whereof I aliix my signature in presence of two Witnesses.

J. W. BURGESS. \Vitnesses H. A. SILVERNAIL, J. E. VEEKES.
