Abstract: 1,191,399. Trouser pressing apparatus. UNIPRESS CO. Inc. 7 March, 1968, No. 11030/68. Heading D1A. A press 'for trousers and 'the like comprises a buck assembly movable between a dressing position and a pressing position where pressing heads 21, 23, 24 are relatively movable to press the trousers, the buck assembly B comprising two vertical support members 137 on which the trouser legs are placed which are carried on a mounting member and each of which has front and rear wings 148, 149 pivoted at their lower ends and movable at their upper ends between expanded and contracted positions, the support members being connected by means below the upper ends of the wings and at about the level of the crotch seam of trousers placed thereon. As shown, presser heads 21, 22 are operated by mechanism 23 relative to the stationary presser head 24 with a steam heated cavity and resilient pads. Fly head assembly 25 comprises a fly head 71 having a steam cavity and is movable by a piston rod 72 and cylinder 73 being connected' to head 24 by two pairs of links 84, 89 and biassed away from pressing position by spring 94. A key (70) in the bottom surface of head 71 extends in a key way (68) in the top of head 24 and engages adjacent resilient strips, Fig. 21 (not shown). The pressing heads 21, 22, whose pressing surfaces fit those of head 24 and fly head 71, are each mounted by a bracket 116 on the lower end of an arm 113 pivoted to an upright 110 on a frame member 109 at the side of the apparatus and engaged by a cam. 120 operated by a piston cylinder combination 122, 127 to move the presser heads to pressing position against springs (134) Fig. 1 (not shown). Arms 129 pivoted to the apparatus frame and connected by rods 131 to the connection between arms 113 and the heads 21, 22 keep the heads vertical when out of pressing .position. The leg members 137 each comprise elongated channels 144, 147 secured together by spacers channels 144 being welded to two plates 140 spaced by spacers 141, 142 and plate 143 welded thereto. Welded to extended portions 147c of channels 147 are apertured ears 606, 602, ears 602 being welded to a crotch bracket 601 and a pin being passed through the apertures to allow relative movement of the leg members. The wings 148, 149, e.g. of stainless steel, are located between channels 144, 147. A clamp 150 pivoted between plates (145) Fig. 26 (not shown) and 146 by members 151 holds the lower edge of plate 148 and the lower edge of plate 149 s held by a clamp 154 pivoted by member 155 to links 156. Member 155 has a rectangular projection 155a off set from the axis of a cylindrical portion 155b which is mounted in the apertures 623 of clamp 154 and is extended through an aperture in plate 149. Each projection ,155a extends into the rectangular portion 621 of key-way slot 621, 622 which is of such size that projection 155a cannot turn therein but portion 155b can be inserted through portion 622. Pivot member 151 is similarly constructed. Links 156 are connected by pivoted arm 158 to control arms 161 which extend upwardly and are pivoted to the piston rod of piston-cylinder combination 167 on plate'143. A control arm 163 pivoted to links 156 is pivoted between plates 145, 146. This arrangement extends the wings. The upper ends of plates 148 are each held between a clamp plate 173 and a bar 172 which is biassed upwardly by spring 178 encircling bolt 175 connecting bar 171 to bar 177 which is pivoted to a link 185 pivoted between plates 140. A control link 188 is pivoted at one end to bar 182 pivoted at its centre to plates 140 and at its other end to bars 191 carried on a pivot 194 on a link 193 pivoted between plates 140. Rearwardly of pivot 194, and depending offset of rocker 198 is pivoted between bars 191 by pivot 199 and through the ends of rocker 198 slide studs 200 biassed upwardly by springs 201 and attached at their lower ends to a block (203) Fig. 8 (not shown) and a mounting member 207. Each wing 149 has a pair of front and rear ears respectively attached to opposite sides of block 203 and member 207. Blocks 204, 203 Fig. 8 (not shown) and the; edge of wing 149 prevent transverse movement of the upper edges of seat wings 212, 211 which are connected by a pin which engages cut out 220 in wing 149 to limit their movement about pivot 210. A piston cylinder combination 521 carries a transverse piece 556 with one end extended between flanges 211a of wings 211 and blocks 213 secured to the respective wings and is urged against blocks 213 to keep the seat wings in extended position. A channel member 223 has one leg riveted' to one wing 149 while the other leg engages the other wing 149 to which is riveted a bracket 225 with a web 225a and a tongue 225b which engage both sides of the web 22a, thus allowing limited relative movement of wings 149. Vertically spaced V- shaped brackets 226, 227 are both rivetted to both wings 148 on offset portions 148c extending forwardly of bracket 601, bracket 227 being narrower than bracket 226 to assist in spreading wings 149 as they are overlapped by wings 148 when retracted. Resilient padding 216 with cloth covering is provided on seat wings 211 and is tapered towards the respective wing 149 at the bottom and rear, the normal thickness of the padding being much greater than that of wing 149. A tapered portion of the seat wing forms a pressing fit with head 24. Wings 212 carry padding 217 and wings 148 carry resilient padding 230 covered with cloth and held partly by clips, the bottom edge being tapered to fit against head 24 during pressing. Cloth covered padding is provided on members 144, 147. Pivoted in a block 276 on the piston rod of an upright cylinder 267 are rods 277, 278. A pivot rod 280 which extends through apertures in plates 140 and, through spacer 141 is connected at one end to an arm 279 keyed on the end of rod 277. A pivot member 282 extends through apertures in plate 140 and through annular member 142 is connected by arm 281 to rod 278. A control arm 285 is clamped at one end to rod 277 and at the other to a stud shaft carrying a cam follower 286. A pivoted cam arm 291 carries a cam 295 with a shaft which extends through a slot 287 in arm 285 and carries a roller of greater diameter than. the width of the slot. The piston rod 245 of a cylinder 246 pivoted from arm 177 carries a block, controlled manually by knob 249, to which are pivoted one corner of each of two triangular plates 250 pivoted about a second corner, the third corner of one plate being connected by a coil spring to pivot 183. Diverging from block 248 are arms 256 having clamps 257 which abut the front edge of wings 148 when in extended or retracted position. Wings 148, 149 are moved by pistons and cylinders 242 on opposite sides of plates 140, the piston rods 243 extending along arms 191 and pivoted to pivot 199. Brackets 311 secured to the machine frame carry bolts 312 supporting sprockets 313 carrying a chain 314 whose ends are connected by block 315 connected to a safety door slidable in guideways 318. Chain 314 is also being connected to block 276. As the buck moves from operating station to pressing stataion which are at the same level it rises and the door rises with it to protect the operator. Pivot 290 extends through cam 330 secured to arm 291 and cam 330 carries an offset 340 to operate switches in a box and other cam surface portions directed in the opposite direction. The cam carries fly switch operating flange 333, 334, 335; cancel offset 336, tabs 337, 338 and cut-out 339 to operate the main neutral switch. Tabs 325, 329 and cut out 327 operate the centre switch and offset 340 operates the end switch. The machine is controlled by switches and timing means which are brought into operation as the various operations take place by suitably placed switches. When the machine is at rest the buck assembly is in dressing position with the leg wings retracted, the fly clamp in clamping position and presser heads 21, 22 in open position. The operator holds a pair of trousers by the waist with the seat away from him and then depresses a foot switch so that a holding circuit is provided through a time switch member. At the same time the buck assembly moves down into the trousers, the fly clamps open and the trousers are finally dressed on the buck assembly. The fly clamp is closed, the seat wings move rearwardly and wings 148, 149 are expanded. The buck assembly is moved to pressing position where fly presser head moves in before pressing heads 21, 22. When pressing is complete the buck assembly returns to dressing position and the trousers are removed.
