To all wlwm it may concern:

'Be it known that I, EDWARD' HENRY iwan, a citizen of the United States, residi.ing' in Philadelphia, Philadelphia county, Pennsylvania, (post-office address care Niles- Bement- Pond Company, Philadelphia,

Pennsylvania) have invented certain new and useful Improvements in For ing Presses and Hammers, of which the "ollowing is a s eciication.

lis invention, relating to a .combined 'hammer endfforging ress will be readily understood from the i) taken in connection with the accompanying i hammer. and press exemplifysing my lnvention: Fig. 2 a side elevatlon, part vertical section, of the same: and Fig. 3 a horizontal section through the hammer-head and its guides.

In the drawing:-1, indicates the hammer-iframeJ of usual steam' -hammer form: 2 'the anvil: 3, the steam-cylinder, supportby the frame: 4, the steam-`V iston: 5, the hammer-rod, connected witlt 1e steam-piston: 6 the hammer-head fast on the lower thel hammer-rod and sliding in vertical. guides 'in the frame: 7, the frameguides for the hammer-head: 8, the steamehest: 9, the steam inlet to the steam-'chestz 10 the 4steam exhaust connection: 11, the y' steam-valvezand l2, the leverfor actuating the steam-valve.

'As thus far described the device does not tmterially differ from an ordinary steamhammer and its operation would be the,

same, that is to say, by actuatin the steamvalve the steam will be admitte to and'exhausted from below and above the steam- -pisto n, alternately, and it is to be understood vthat the illustrated steam-valve with its actuating mechanism is merely typical and-that any of the'usual appropriate valves mer-head concentriewith the hammer-rodv and closed at its lower end: 14, :i plunger Specification of Letters Patent. i Application tiled September 17, 1909.

rigidly supported bythe frame and rojecting down mto the water-cylinder tirough suitable packing: 15, a water passage leading through the plunger to permit Water to flow to and from the water-cylinder: 16, a water-valve casing connected with the water passage 15:17, a water inlet for the watervalve casing: 18, a water. outlet from the water-valve casino: 19, a water inlet valve to control the dow of `water from the water inlet to the water-cylinder: 20, a water outlet valve to control the flow of' water from the .water-cylinder to .the water outlet .18: 21, arocler adapted to open, eitherr` of the' ywatervalves,

selectively 22, a' lever foractuating the rocker: 23, a flange formed in the upper end of plunger 14 and restingon the general frame o the structure;` and 24, studs securing flange 23 firmly to the hammer-frame and projecting upwardly into engagement with the stcamcylinder to serve in unit-ing the steam-cylinder firmly to the 'hammerframe.

As the parts are shown in Fig. 2 the inlet water-valve is closed and the outlet water- -valvc 4is open so` that the water-cylinder is Without pressure and, for the time being, Without oice. The steam-valve is in osition to admit steam above the steamiston vand, to permit steam to exhaust from elow corresponding with the beginning of the down stroke'of the hammer when employed as a steam-hammer. VVhe'n the hammer, acting as a steam-hammer, has completed its the piston, the steam-valve being in position down stroke then the steam-valve will be reversed andthe steam be permitted to exhaust from above the steam-piston while live steam enters below the steam-piston and lifts thehammer again.

Looking at Fig. 2, assume, now, that the steam-valve be shifted so as to admit live steam below the steam-piston and exhaust the steam from above the steam-piston, and -assume that the valve be left in that position, the hammer will then be raised by the steamfpiston'eand be held in raised position.

Assumin now, that,the' niachine is to be used as a erging press, the steam-'valve being in the position j ust'mcntioned, the hammer being supported in upward position by the steam pressure below the steam-piston. By yproperly shifting the lever 22 the water 'otlet valve' 20 will be closed and the Water inlet valve 19 vvill be opennthus admitting water to the Waterfcylinder Lnnder pressure,

being understood that the Water inlet 17 is 'connected with the source of supply of water The Water acting in' under heavy pressure. the. Water-cylinder forces the hammer-head down, against the yielding resistance of the steam under the steam-piston. `\Vlren it is desired that the hammer rise then the. lever 22 is actuated to close the water inlet valve and open the Water outlet valve, whereupon the steam acting under the Steam-piston will raise the hammer-head. In this manner the device is employed as a forging press.

It is to be observed that the general machine stands ready for instant selective use' either as a steam-hammer or as a forging press, the parts of one member of the system not interfering at all with .the action of the parts of the other member of the system.

It is to be understood that the water-valve mechanism specifically illustrated is merely typical and that it may find its equivalent in appropriate valvular mechanism for controlling the flow of water to and from the Water-cylinder. The location of the watercylinder within the hammer-head to cooperate with the fixed lungeris a matter of preference as compared) with' the fixed cylinder coperating with the plunger moving with the hammer-head.

I have set forth the principle of the invention and thetbest mode -in which I contemplate embodying that principle, and the structure specifically set forth is to be viewed as a single exemplifieation of the invention.

It should be understood that itis not new to combine a steam hammer and a hydraulic press in such manner'that a hammer-head may do'its work by blows or by pressure as desired, but it shouldv also be understood that where this has been done the hydraulic press quality of the combined machine has been made primary while the steam hammer has been ofthe nature of a secondary adjunct. -The result has been `that the steamhammer feature -of the machine has been lacking in many of the qualities found in steam hannncrs not conjoint with hydraulic presses. In my machine the steam-hammer is the primary agent, the hydraulic press being supplemental or secondary, and the construction is such .that the steam-hammer has all of the virtues-oi ordinary steam-hammers notwithstanding the presence of the hydraulic press. For instance, it will be noticed that in my 'constrlution the han'nnerrod forms a dii-.cot connection extending axially from the steam piston to the hammer-head after the n'ianncr of ordinary steam-'hannners, the hydraulic press not interfering with this direct connection of the hammer rod because the cylinder and plunger of the lhydraulic press surround the ham- .mer-rod, 1n other words, the hammer-rod passes axially through the hydraulic press. I claim 1. A forging press and hammer compris-i ing, a frame, a steam cylinder supported thereby', a' hammer-head fitted to slide in the frame and disposed below the steam c linder and in its axial line, a hammer-rod ,'rectly connecting the steam-piston and hammerhead, valvular mechanism for controlling" the ow of steam'toand from the` steam cylinder, a water cylinder, a plunger ,inf the water cylinder, the Water cylinder and plunger' surrounding the hammer rod between the steam-piston and hannner-head and forming `a coperative couple one of Whose members 4is connected with the hammerhead, and valvular mechanisxnfor contr'olf ling the flow of water to and from the water cylinder, the two valvular mechanisms being independent of each other", combined substantially as set forth.

A forging press and hammer ,compris-.

ing, a frame, a steam cylinder supported thereby, a hammer-'head fitted to slide in the' trame and disposed below the steam cylinder and in its axial line, a hammer-.rod directly connecting the steam-piston and hammer-head, valvular mechanism for controlling the flow of steam to and from'the steam cylinder, a Water cylinder' formed the 'hammer-head, a plunger rigidly. supported by the frame below the lsteam cy inder and projecting down into the Water cylinder, the water cylinder' and plungersurrounding` the hammer-rod and having their axes coincident with the axis'of the hammer-rod, and valvular mechanismto'r controlling the flow of water to and from the water cylinder, the two valvular mech"- anisms being independent of each other, combined substantially as set forth.
