Each of the motors includes a cylinder 228 and a piston 222 reciprocable in the cylinder.‘ The piston is provided with a head 224 compression stroke. having an extension 226 on which is ?tted a leak 65 grip I48. vUpon depressing the lever I36 the shaft I32 is moved through an angle, and this movement is transmitted through the arm I38 70 > . A valve chamber I42 formed in the base of the reservoir has a port I44 which provides a com munication between the valve chamber and the reservoir, and a port I46, the purpose of which will hereinafter appear. A valve cage I48 is ?tted 75 in the chamber I42 and is retained against dis proof cup 228. The extension 226 has a diametral bore 238 communicating with an axial bore 232 extending through the piston and the extension. A bleeder screw 234 is threaded in the bore 232 in the piston and ?tted on the back of the piston is a cap 236 enclosing the bleeder screw 234. As 2,125,585 shown, the piston is held against displacement by a retaining ring 238 seated in a circumferential groove in the wall of the cylinder adjacent the open end thereof. 3 ?uid pressure motors 2I6 and 2I8 are in re tracted position in which position the buck is held against the pistons by the springs 266; under these conditions,‘ the operator places the work 4 The motors 2I6 and 2I8 are connected respec tively by conduits 2'46 and 242 to a coupling 244, upon the buck and lowers the head 268 into opera and the coupling is connected by a conduit 246 the thicknessof the work. tive position, which position varies- according to to the discharge port of the compound cylinder ~ 56 with the check valve 68 interposed, and by a 10 conduit 248 to the port I46 in ‘the valve cham ber I42.

As shown, the rods have 25 heads 262, and sleeved on the rods between the heads 262 and‘ retaining rings 264 seated in cir cumferential grooves in the sleeves adjacent the open ends thereof are coiled springs 266. The springs 266 serve to retain the buck M4 on the 30 caps 236 on the back of the pistons 222 in the cylinders 220 and to return the pistons 222 to their‘ retracted positions. - An ironing head 268 adaptable for cooperation with the buck 250 is pivotally connected to. op 35 positely disposed horns 210 formed on one end of a hollow arm 212, the other end of which is ?ared as indicated at 214 for the reception of the spherical portion I6 of the column I4‘. The arm 212 has an internal web 216 and this web. has ‘an 'in This arm extends downward into the column I4 and is pivoted to the spherical portion I6 of the column I4. A yoke 280 is piv oted on the arm 218 and is connected by coil 40 tegral arm 218. springs 282 to an, adjustable member 284 mount 45 ed on the frame I0. ' ‘ Upon the completion of an ironing operation, the springs 282 actuate the arm 212 to move the head 268 to the elevated or inoperative position. A bell crank lever 286' is pivoted on the frame I0. 50 One leg of this bellcrank lever ‘is pivotally con nected to one end of a link 288, the other end of which is pivotally connected to the arm 218. The other end of the bellcrank lever carries a pin 280 adapted to enter the forked member 202 when 55 the head is lowered into operative position. To vfacilitate in lowering the head intovoperative position, a rod 282 is attached to the arm 212 be 60 movement of the arm I30 transmits force through the thrust rod I28 to move the piston 10 on its compression stroke. Simultaneously therewith, the arm I18 is rocked through an angle, and this movement of the arm I18 disengages the spring pressed plunger I82 from the notch I80. During the initial movement of the piston 10 on its compression stroke, the leak-proof cup 88 ,on the head 14 of the piston covers the port 64, and the ?uidin the chamber 58 is displaced there from through the ports I02 in the head 16 of the piston, past the leak-proof cup I08 into the cham ber 60, thence through ports 66 and past the check valve 68 through conduit 246, coupling 244, and conduits 240 and 242, into the motors 2I6 and 2I8, also through conduit 246 into valve chamber I42, thence through port I88 into cylinder I84, resulting in actuation of the ?uid pressure motors 40 Further increase of pressure results in actua tion of the pistons 222 in the motors 2I6 and 2I8 and the consequent movement of the buck 250 against the head 268; Simultaneously therewith, 45 pressure is built up in the cylinder I84 against the face of the piston I90, resulting in applying force through the thrust rod 200 to the bell crank lever 286 retaining the lever 286 against move _ ment, thus effectively retaining the head in oper 50 ative position.
