This lrod is .proof its stroke. vided with a cross head 2l for carrying pins or 'I'he power means illustrated includes a vertifollowers 22 ladapted to move freely ln vertical 555 slots 23 in the angles I3. The followers 22 also ride in suitable slots 24 in cam plates 25 mounted on the swinging arms I2. Fluid pressure is admitted to the lower part of cylinder 19. During the first portion of the stroke of the piston rod,

Y illustrated the upper endv 28 of the piston rod positioned in a manner to contact the lower end of stem I6 when the head and bed are in registration'. Therefore, the rod, during the latter part fof the power '.stroke, presses the buck against the head.;

" For controlling the fluid pressure, I have illustrated a duplex valve 29 of a standard type with .an operating handle 30 easily accessible to the operator. l 1

For. opening the press and moving the buck to made-double acting so that the pressrwould be opened by applying pressure to the upper end of the cylinder I9 and thus quickly return the parts toyposition by` movement of the piston 20 and followers 22 downwardly in the cam slots 24. IV

- have. chosen,. however, ,to Villustrate mechanism for relieving the pressure beneath the piston and opening the exhaust by means of the valve 29 `and thereafter permitting the parts to return tothe position shown in Fig. 1 `by their own Weight,

".'I'heconstruction-of valve 29 is shown in detail in Figs4 and 5. The main chamber 45f has an inlet port 46 closed. by valve 41., and anl exhaustY port 48 adapted to-.be closed byvalve 49. Theexhaust port communicates with exhaust conduit 50. Theinlet port communicates by thelateral chamber 5I, through Vneedlervalve 52, with the inlet conduit 53. The valve chamber .45.V communicates through port A54 and conduit .55n with the, lower .side of therpiston I9. The vent conduit..56 connects the upper part of cylf inder. I9.with the exhaust conduit. When valve '.49 is closed and valve 41 is. open, fluid pressure,

lcontrolled by' needle valve 52 enters cylinder I9 and raises the piston. When the valves are reversedthe pressure is relieved through conduit 55, chamber 45, port 48 and conduit 50. The .escaping pressure may flow by conduit 56' to the .space above piston ,I9', thereby equalizing the pressure on Yeachsiderand allowing free opening movement. y For counterwelghtingY the parts, I kprovide weights 3I rigidly carried on a rock shaft 32 piv- `otallysuppcrnrted in brackets 33 mounted on Vthe frame. .The rock shaft is connected to the moving buck byV a link 34 rigidwith'the'shaft and a link 35 pivoted to the arm I2. i

Additional means is provided for holding the buckiiniregistration with the head duringthe closing of the press. j. The means shown comprises levers 36 having notches 31 adjacent their Ainner ends, these levers being rigidly mounted adjacent their central. portions on rock shaft 38 4whichA is pivotally supported on the brackets 33. .ll`hegouterV ends Yof the levers are pressed Yby Vsprings 39 against.theshaft32. 4 Pins 4l)V on the buck carrying arms are adapted to enter'the lina clockwise direction. A projection 43 on the piston rod is arranged to contact the latch, this projection moving the latch idly about its shaft during the upward movement of the piston rod, but acting to depress the levers 36 upon the downward movement of the piston rod, thus releasing the pins from the notches 31. l

The press and its working. parts may be en-V closed in a casing 44, which completely surroundsthe machine except for an opening in the upper portion of the front panel access to the buck.

The operation of the machine With the parts in the position of Fig. 1, the operatorarranges the lay of the work on the buck I I. The control lever 30 is moved upwardly, admitting fluid pressure throughvalve 29 to the lower side of the piston. 'I'he rod 20 moves up, carrying the followers 22 along vthe portions 26 of the cam slots 24, thus moving the parallel arms I 2 to vertical position so that the buck is in registration beneath the head. The pins 40 on arms I2 enter the notches 31 inlevers36 to hold the,Y pressing, elements in registration. During the further upward travel of the piston, while followers 22 move in portions 21 of the cam slots, the upper extension of the piston rod 20 contactspthe stem I6 of the buck and raises the buck from its support I4 into pressing Y. engagement with the head. 'Y i f When the WorkA is sufliciently pressed,'the operator reverses the control lever, Vthus relieving the .which provides is as followsr- I pressure from the lower side of the piston. The

Vpower stroke ofthe powermechanism.Y The reverse stroke of the mechanism is adapted to open the press and returnithe buck to loading position. VThe operator, by the movement 'of'one valve, easily controls the entire operation of the press. more easily operated than pressesrnow in use.

Two means are provided for holding the buckV and head in registration during theY closing of the press, one being the'power actuated follower travelling in the cam slot and the other Vbeing the interlock between the frame and the swinging The machine also requires butv a small amount of floor space. A n additional advantage My improved press is therefore faster and.

will be seen from an inspection of 2, Yshowj ing the press in closed position, the final pressure being applied through Lstraight rods, thus permitting a ver-y light construction of the frame.
