ALBERT G. HRON, OF KEWASKUM, WISCONSIN, ASSIGNOII TO KEWASKUM ALUMINUM p co., or KEwAsKUm-WTSCONSIN.

l PERCOLATOR.

v Application filed March 22, 1929. Serial No. 349,144.

v This invention pertains to percolators, and more particularly to thatl type commonly known as Coldwater percolators, in whichL rigid and secure joint is obtained, vwhichV avoids possibility of Vleakage or loosening of the base from lthe'receptacle. y

Incidental to the foregoing, al more specii'ic object resides in tlieprovisio'n of a cast base having an integral portion beaded over with a portion of the receptacle to form the attaching joint.' Y g l A still further object is to provide a cast aluminum base with an integral sleeve of pliable metal, adapted to project through the bottom of the receptacle and to be crimped over a portion of the receptacle on the interior of the same, thus rigidly clamping the receptacle tothe base.`

Vith the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction combination andA arrangement of parts substantially vas hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of theherein disclosedinvention may claims. n .Y f

In the accompanying drawing is illustrated one complete example` of the physibe made f as comefwithin` the'r scope of the' ca'l embodiment of the present inventionconstructed according to the best mode so far devised for the practical application of the-*principles thereof. f

In the drawing,r Figure 1 is a vertical section through a portion ofa percolator con-A structed in accordance with the present invention, and K f Figure 2 is" a detail section of the same prior to crimping the receptacle to the base.

Referring now more particularly to the accompanying drawing, the numeral l designates a portion of a conventional percolator receptacle, which it is understood is yprovided with the usual spout and handle, not shown. The bottom of the receptacle l is provided with a central annular opening 2, surrounding which is van inturned beadV 3 formed by crimping the material? over in a manner hereinafter' described. Associatedwith the bottom of the receptacle .is a cast base l provided with the usual central well 5, which cooperates withthe fountain to cause the contents of the receptacle to vpercolate through the .material contained in the usual reservoir, not shown. The top of the-base 4L is providedwith a fiattene'd sur-y face '6, which lengages the bottom of the receptacle adjacent the central opening 2. l y

In the present instance, in which ,the. base 4 is cast from aluminum, a cylindrical sleeve 7 is provided for the-well, the same being cast integrally with the base toV form asecure connection. The upper end of thek sleeve 7 projects through the central Opeliing 2 and is crimpedY over the internal bead 3 formed in the receptacle and thus cooperates with the iiat upper surface 6 to rig- ;y

idly and securely clamp the receptacle to the base. A

As best shown in Figure 2, the present structure lends itself to an inexpensive operation of. assembling, in that prior tothe crimping operation, the receptacle is merely assembled upon the base with'the sleeve 6 projecting through .the central opening and surrounded by an upturned portion ofthe i receptacle. Thus, in the crimping operation, `both the sleeve anda portion of the receptacle are turned over simultaneously, which not only permits the sleeve and` re-f ceptacle to be securely clamped together, but. also eliminates a separate operation in forming thefbead 2. l From the foregoingA explanation it willl be v obvious that an exceedingly simple andeffectivejointhas been provided between the base and receptacle, which eliminates possibility'of-leakage or of the receptacle becoming loosened. It is further pointed out that the particular advantage of providing a cast aluminum base'with an integral sleeve insert of pliable metal, materially facilitates the crimping 'Y derstood that although the present form is also contemplates a structure in Which. the projection of the base may be cast integral with the same instead oi' comprising a separate sleeve moulded into the base duringthe casting operation.

As previously explained, the Well 5,

formed in the base, cooperates with the fountain in the conventional manner. The fountainv illustrated comprises the usual fountain tube 8 which communicates with the valve chamber 9, which is provided with a cylindrical sleeve l() removably mounted Within the Well 7. In the present instance, the fountain is shown supported by engagement of the sleeve l0 with the bottom oi' the Well. However, it Will be appreciated that the length of the sleeve may be materially reduced, and any means provided tor supporting the same on the inturned bead of the sleeve 7. y

Although the fountain has been described in some detail, no novelty is embodied in the same, nor does it constitute any part ot' the present invention other than in the broad combination.

Iiclaim:

1. A percolator comprising a receptacle provided with a central opening in it-sbottom, a base, and an integral extension carried by said base and crimped over the edge of said central opening to 'lform a tight joint between the receptacle and base.

2. A percolator comprising a receptacle provided with a central opening in its bot tom, a base provided with a Well in 'align ment with said central opening, and an integral extension carried by said base and projecting through said opening and crimped over the edge of the same to form a tight joint between the receptacle and base.

3. A percolator comprising a receptacle provided with a central opening in its Ybottom and an internal bead surrounding said opening, a hase provided with a Well in alignment withV said central opening, vand an integral extension carriedby said base and crimped over the internal bead of the receptacle to 'lorm a tight oint betvveenthe receptacle and base.

4. A percolator comprising a receptacle provided with a central opening inA its bot tom and an internal bead surrounding said opening, a base provided with a Well in alignment with said central opening, a sleeve secured in said Well and projecting through toni, a base provided With a Well in alignment with said central opening, said base having a flat upper tace engaging the bottoni of said receptacle, and an integral extension carried by said; base and projecting through said central opening and crimped over the edge of the same to clamp said receptacle upon the fiat upper 'face of said base.

7. A percolator comprising a receptacle provided with` a` central opening, a cast aluminum base provided With a Well in alignment with said opening, a pliable metal sleeve secured in said Well and projecting through said central opening and crimped over the edge of the same to clamp said rc cept-acle to said base.

8. A percolator comprising a receptacle provided with a central opening in its bottom, a cast aluminum base havinga vvell in alignment with, said central opening, and a pliable metal sleeve cast inl the Well oit said base and projecting through said central opening and crimped over the edge thereof to securely clamp the receptacle to the base.

9. In a percolator comprising a receptacle provided, with a central opening in its bottom surrounded by an inturned. bead, a cast aluminum base provided withy a Well in alignment with said central opening, said base being provided with a flat upper face engaging the bottom of Said receptacle, and a pliable metal sleeve cast integral with said Welland projecting through said Well and projecting through4 said central4 opening and crimped over the internal bead surrounding the same to securely clamp the receptacle to the flat upper face of the base.

In testimony that I claim the foregoing I have hereuntol set my hand at Kjevvaslium, in the county of Washington and State oi' Wisconsin.
