SHEET-METAL CYLINDER FOR LARD-PRESSES.

SPECIFICATION forming part of Letters Patent No. 769,435, dated September 6, 1904.

Application filed July 7, 1904. Serial No. 215,607. lNo model.)

To all whom it may concern.-

Be it known that I, CLARENCE GREGORY GARRIsUs, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Sheet- Metal Cylinders for Lard-Presses, &c., of which the following is a specification.

My invention relates to improvements in cylinders for lard-presses or presses for lard, fruit, or sausage-meat, &c.; and the object of my improvement is to make the body and bottom of the cylinder from a single piece of sheet metal and provide efficient means for attaching the spout to the said sheet-metal bottom.

In the accompanying drawings, Figure 1 is a plan View of my lard-press cylinder. Fig. 2 is a broken-out side elevation of the same. Fig. 3 is a sectional view of the lower part of the same on the line .1 of Fig. 1, and Fig. a is an enlarged detached section on the same line of a portion of the spout in the form that it has before it is attached to the bottom of the cylinder.

A designates a sheet-metal cylinder the sides 5 and bottom 6 of which are formed of a single piece of sheet metal. A circular hole is punched'or otherwise cut out of the bottom 6 near its center to receive the mouth 10 of the spout and to facilitate attaching the spout 7 to the said bottom. The spout? is formed of malleable metal, and the mouth 10 is provided with a projecting rim 8 of a cylindrical form on its outer side when first formed, as shown in Fig. 4, and having a flange 9 surrounding the said rim, with the face of the said flange perpendicular to the outer or cylindrical side of the said rim.

In order to insure a snug fit and to facilitate turning over the rim 8, a milling-tool or sweep is employed to dress off the upper face of the flange 9 and the outer side of the said rim, so that it will snugly lit the hole in the bottom 6, while the top of the flange will closely fit the under side of the bottom immediately surrounding the said hole. The same mill or sweep may also sweep or dress off the inner face of the rim 8 inside the mouth, so as to leave a clean surface for the swaging or bending tool. \Vhen the spout has been thus fitted to the bottom, it is first secured thereto by rivets 11, passing through the said bottom and flange. After thus securing the spout by rivets the upwardly-projecting portion of the rim 8 is turned over outwardly upon the edge of the metal surrounding the hole in the bottom, changing the said rim from the form shown in Fig. 4 to that shown in Fig. By

this means a perfectly-tight connection be tween the sheet-metal bottom of the cylinder and the spout may be made which will be efiicient under the great strain to which such cylinders are subjected.

I claim as my invention A cylinder for lard or analogous presses having a sheet-metal bottom and a separatelyformed spout, the said spout having a rim and surrounding flangeat its mouth, with the said rim extending through a hole in the said bottom and the flange resting on the under face of the bottom, the said flange being riveted to the said bottom and the said rim being turned over inside of the cylinder upon the edge of the metal surrounding the said hole in the bottom.
