ADJUSTABLE HYDRAULlC CYLINDER FOR FLANGlNG-PRESSES.

I SPECIFICATION forming part of Letters Patent No. 550,916, dated December 3, 1895.

Application filed September 20, 1895. Serial No. 563,061. (No model.) i

To all whom it may concern.-

Be it known that I, EBENEZER A. W. JEF- FERIES, a citizen of the United States, residing at the city of Philadelphia, in the county .of Philadelphia and State of Pennsylvania,

have invented certain new and useful Improvements in Adjustable Hydraulic Cylin ders for Flanging-Presses, of which the following is a specification.

My invention has relation to a hydraulic fianging-press of the type in which the flanging-die is carried by the ram or piston of a hydraulic cylinder; and it relates to the construction and arrangement of such hydraulic cylinder, whereby the same may be adjusted in the head-plate carrying or guiding the cylinder for the purpose of fianging fire-box mouths of locomotive-boiler fronts and other similar articles.

The principal objects of my invention are,

first, to provide in a hydraulic flanging-press a die adapted to flange fire-box mouths for locomotive-boiler fronts and other similar articles in which the position of the interior opening is variable, and, second, to provide in a hydraulic flanging-press a die carried by the piston of a cylinder adjustable laterally or longitudinally or in both directions in the head-piece of the press.

My invention, stated in general terms, consists of a hydraulic cylinder operating a flanging-die adjustable in the head-piece of the press; and my invention further consists of an adjustable die-carrying cylinder for hydraulic flanging-presses constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure l is a top or plan View of the headpiece and supporting-standards of a hydraulic flanging-press embodying features of my invention and illustrating in connection with said head-piece the laterally-adjustable diecarrying hydraulic cylinder in said headpiece. Fig. 2 is a front elevation of the upper part of a hydraulic press embodying features of my invention and illustrating the head-piece and adjustable die-carrying cylinder adjustable longitudinally therein;

Fig. 4is a top or plan view of the headandFigs. 5 and 6 are respectively front and side views of an 'unflanged and flanged blank for a fire-box mouth of a locomotive-boiler front.

Referring to the drawings, a represents the head-piece or table of a hydraulic flangingpress screwed or otherwise secured to the upper portion of the columns or supportingstandards I). At approximately the center of the head-piece or table a and extending through the same is formed a slot d, which, as shown in Fig. 1, extends laterally across the head-piece or table a, or a slot e may be formed in said table at, extending longitudinally therein, as illustrated in Fig. 4. These slots each cross the middle or center of the table a and are slightly larger in width than the external diameter of the hydraulic cylinder f, whose piston or ram carries the flanging-die. (Not shown.) Within the slot (l or 6 may be located the cylinder f and secured in any desired position therein.

The means which may be employed is as follows: The head-piece a is provided on either cured to the plate (Z or e and the head of the cylinder secured to the table a by screwing down upon the plate the nuts (1 or e of the bolts, thus clamping the plate and cylinder to the table. When the cylinder is to be shifted, the nuts of the bolts are loosened, and the heads and stems of the bolts are thereby permitted to move in the slots or grooves (Z or e of the table.

In flanging the blank h, and'particularly the internal opening 11, of a fire-box mouth for a boiler front or similar blanks it is necessary that the die carried by the piston of the hydraulic cylinder be adjusted so as to register with said opening *6, because this opening in blanks of this character varies in its position even in boiler fronts of the same size and shape. To permit of the adjustment of such die, is provided the adjustment laterally or longitudinally of the hydraulic cylinder f in the piece or table a, and thus to bring the die carried by the piston of the hydraulic cylinder into any desired position to register with the p The successive po- 1 sitions of the cylinder f are indicated in full openings 1' of the blank.

and dotted lines in Fig. 1 of the drawings.

Having thus described the nature and objects of my invention, What I claim as new,

and desire to secure by Letters Patent, is

1. In a hydraulic flanging-press, a head/ piece or table, a hydraulic cylinder and piston or ram carrying a flanging die, and means for adjusting said cylinder in said head piece or table to vary the position of said die, substantially as and for the purposes described.

2. In a hydraulic flanging-press, a headpiece or table having longitudinal or lateral openings and a hydraulic cylinder adapted to be adj ustably secured in the openings of said to said head-piece by said bolt to secure the cylinder, substantially as and for the purposes described.

In testimony whereof I have hereunto set my signature in the presence of two subscribing Witnesses.
