To n/ZZ whom it may con/cern,.-

Be it known that I, CAsIMIR voN PHILP, a citizen of the United States, and a resident of Bethlehem, Northampton county, State of Pennsylvania, have invented certain new and usefulA Improvements in Fluid Pressure Metal-Working Machines, of which the following is a specification.

This invention comprises various improvements in fluid-pressure metal-working machines such as are employed for langing or riveting metal plates and for other purposes.

The invention will be described in detail in connection with the accompanying drawings, in which- Figure 1 is a' vertical section on the-line a b of Fig. 2 of an apparatus embodying my invention. Fig. 2 is a top plan view of the apparatus, the upper pla-ten being broken away, so that the lower platen may be seen. Fig. 3 is a section on the line c d of Fig. 1. Fig. 4 is a vertical section of the working cylinder mounted on the up er platen and Fig. 5 is a top plan view of t e Workin cylinder with the head removed, showing tIie plunger and plunger-guide.

Referring to the accompanyin drawings, the apparatus comprises a suita le foundation on which is mounted a bed-plate A, supporting uprights B. Upon the uprifrhts are slidably mounted .an upper platen O and a lower platen D. Fixed to the bed-plate A is a hydraulic device E for raising the lower platen D. The bed-plate A also supports hydraulic jackcylinders F, the plungers of which may extend above the lower platen -for supporting the work. Adjustably secured within the upper platen C is a hydraulic cylinder G, the plunger ofwhich carries a tool or is otherwise suitably arranged and constructed to work upon the metal.

The upper platen O may be secured in any desired position upon the uprights B by means of lock-nuts 1, engaging with screwthreads upon the uprights. The upper platen has a slot 2, wit-hin which the cylinder G is slidably mounted. The cylinder G has lugs 3, which rest upon'the top of the platen and also lugs 4, which extend into grooves 5, cut in. the sides of the slot 2 and between the upper and lower faces of the platen C. By this construction ease of movement and security in position of the cylinder G is secured.

The interior ofthe outer cylinder 6 is of the usual cylindrical form, within which its a hollow plunger 7. At the top of the plunger is secured a cylinder-rin 10 by a ring 11, fixed to the end of the p un er by bolts 12. Farther down the plunger is ormed a lug 13, by means of which a second cylinder-ring 14 is secured to the plunger. At the bottom of the cylinder a similar c linder-ring v15 is secured by a ring 16 and h der. A short distance from the bottom of the cylinder a lug 18 is formed upon its interior, which lug operates to secure another cylinder ring 19. A guide 9, iixed to the head of the cylinder, has longitudinal grooves 20, into which extend lugs 21, fixed to the interiorof the plunger. In order that the lugs may fit the grooves accurately, liners 22, machined to fit the grooves, may be secured to the lugs. The coperation of the lu s and grooves prevents turning of the p unger within the cylinder, and thereforeprevents twisting of a tool which may be carried by the cylinder with relation to the work. The space within the plunger may be connected with a source of fluid-pressure, as a head of water, by means of a pipe-connected with an opening 23. y sections 24 and 25, whic are jointed to each other, Vso that they may turn. The other ends of thesections are jointed to the cylinder 6 and to a stationary-pipe-head 26, secured to an upright B or Vother stationary portion of the apparatus. the pipe-sections 24 and 25 are of suHicient combined length to permit the cylinder G to move to the end of its travel, while the oints between the stationary pipe, the cylinder, and between the sections are such as to permit the flexure of the pipe-sections, so that the cylinder G may be moved along the slot 2. The opening 23 is also connected to an outlet pipe which may be controlled by a valve in any suitable manner.

In the outer cylinder 6 is a hole 28, which connects with a source of pressure and also with an outlet in a manner similar to that noted in connection with the opening 23. The hole 28 opens into the outer cylinder between the cvlmder- rings 14 and 19. If now the controlling devices be so turned that the space between the cylinder- rings 14 and 19 and between the plunger and the outercyl- As will be noted,

olts 17 to the cylinlOO ' is connected with the source of pressure. The

' being connected to .the cylinder and the other' plungerwill be then forced 4upwardly into-.po-

sition for lanother stroke.

As 'before stated, vthe cylinder y.Gr .ma be moved along fthe slot 2, and it .may beehe d in any desired position by means ofclampingscrews 29,.carried bythe lugs 3 and engaging! with the top of the upper platen. The cylinder;` G may -be moved along theslot 2 -by a .relatigvely movable screw 3U' and sleeve 31,

whicharein engagement with each other,.one

to the platen'. The .relative :movementmay -be effected by means of .a squared end 32 upon the screw, to which a wrench `may be applied.'

The lower platen D is fixedto a plunger 33,v the 4hydraulic device E, which vis .supported vin 4the bed-plate itted within. thecylinder of A. The space vwithin the cylinder .between it andthe plunger eis connected in any suitable. manner with ,a source of 4pressure and also :has suitable Vmeans of exhaust. When theexhaustis closed andthepressure connection opened, ythe-plunger 33 will be forced upthe .platen with it, the d lswardly, carrying tance .to whichthe. laten is moved -fbeing regulated by controlllng they pressure connections. If vit -be desired to lower the platen, the -pressure connections are closed', .while the exhaust'is opened, when the platen and -plunger lwill -fall ,by'their own welght. U onthe bed-plate ,are fmounted @wooden bu ers 34, against which the platen strikes on its return movement. The use'of wood in this connection .has-'beenffound peculiarlyadvantageous,

as it secures the stoppage of theplaten without l undue shock.

The jack-cylinders F com rise-an outer cylinder in which is mounte means for=admitting.pressur'e toand .releasing ressure :from :the space within the cylinder eneath .the .plunger :infany suitable manner. Each'gjack gis slidably mounted ulplen .a .radially-extending track 35, along w 'ch it may be moved by means of avrelatively movable nut 36 and screw 37, which engage with each other and are connected one-tothe jack-.cylinder and the other to the bed-plate, sothat-they may lhave relative movement, Aand .thereby cause the cylinderto move alongthe track. :In the resent instance the nut is shownasx'ed to t e 1jack-cylinder, while the screw Ais1-om- -tably secured to the 1bed-plate and extends a plunger with parallel to the track. 4Slots 38611 the lower platen permit the plungers of the jacks to extend .above Athe said platen, :and fas z'dhe fslots -are parallel to the tracksmovement of the jacks along the tracks is permitted. The jacks F are obviously proachtoward the-center of the platen, and therefore any work which Ais supported -upon the plungers of .the jacks is necessarily unsupported in the center.. It may, however, ybe desirable under some circumstances that the center of the work be supported. To accomplish this, a second plunger'39 is mounted ywithin the iplunger3 of thecylinder E.

The dotted lines in Fig. 1 show the machine arranged to operate as a Hanging-press. The plate 43 to be' flanged rests upon a die 44, supported by the projected plungers `of the jacks, the Hanging being performed by the head 45, secured to the plunger 7, which is projected against the' plate in a manner` before described.
