The preferred form of construction as illustrated in the drawings comprises a suitable supporting frame 15 having a suitable hollow pressing buck 16 supported on the top of said frame on a suitable standard 17 and whereby said buck is available for the reception and support of articles for pressing and ironing, as will be readily understood. The buck 16 is supplied with steam through a supply pipe 18 for maintaining the same in heated conditiorn (lo-operating with the buck 16 is a hollow pressing and ironing head 19 supported on two hangers 20 slidable on a transverse uide rod 21 mounted at the forward end 0 two supporting arms 22'a'nd 23. The supporting arms 22 and 23 are connected at their rear ends by means of a cross bar or yoke 2 1 thereby providing a supporting frame and said supporting frame is mounted for vertical movements bymeans of two slide rods 25 slidable in suitable bearings 26 at the rear of the frame 15. By this arrangement, it will be noted, that the head 19 is mounted for vertical movement into and out ofoperative relation with the buck 16 and is also mounted for lateral movement on the guide rod 21.

V On'its top, the head 19 carries a transverse rack bar 27 meshing with a pinion 28 at the forward end of an. operating shaft 29 which in turn carries a pinion 30 at its rear end meshing with a vertical rack bar 31, as best shown in Figs. 1, 2 and 3. The rack bar 31 is mounted to reciprocate in the vertical gu ide housing'32 which may be fixed on yoke 24, the upper end of said guide housing limiting the upward movement of the rack bar and thereby limiting the relative movement permitted between the rack bar 31 and its co-operating pinion 30." The rack bar 31 is formed onthe upper end of a piston rod 33 connected with a piston 34 in a vertical steam cylinder 35 mounted at the rear of the frame 15, as best shown in Fig. 2. The cylinder 35 and piston 34: serve as a means for vertically reciprocating the rack bar 31 when'desired.

By this arrangement, it will be noted, that when the rack bar 31 is resting against the top of the housing 32 and the piston 34 is lowered in the cylinder 35, the head 19, by the controlling action of said rack bar, will be lowered into operative engagement with the buck 16. As soon as the head 19 operatively engages said buck, further lowering of the head is prevented by reason of the lost motion or separable connection between the head and rack bar, and further lowering of the piston 34 causes relative movement between the rack bar 31 and the pinion 30. This relative movement causes rotation of shaft 29 and consequent lateral sliding or movement of the head 19 to effect an ironing action on an article on the buck 16, as will be readily understood. The ironing action thus induced results from the lateral sliding or slip between the pressing head and the buck and closely resembles that employed by the human hand in the ordinary ironing operation in that it produces either a partial or a full gloss of the surface of the goods being ironed depending upon the degree of pressure and heat.

Upon the return or up-stroke of the piston rod and rack bar 31, the pinion is rotated to move the head back laterally, resulting in a reverse ironing action, and upon reaching the limit of the rotation of the pinion, further movement of the piston red, by means of the lost motion connection, raises the head off the buck to its initial position.

A stop collar 36 is mounted on the piston rod 33 and arranged to engage with oppo sitely disposed rocker arms 37, best shown in Figs. 2 and 6. These rocker arms 37 are pivoted at their outer ends to the upper bearings 26 and are connected with the upper ends of push rods 38 carrying compression springs 39 resting at their lower ends in pockets on the cross bar 40 of the frame 15. By this arrangement, it will be noted, that as the head 19 is lowered into operative engagement with the buck 16, the lowering movement is cushioned by the cushion arms 37 and shocks and jars during operation thereby prevented. A stop nut 41 is arranged at the lower end of each push rod 38 to limit the upward movement thereof and suitable nuts are provided at the upper ends of said push rods for adjusting the tension of the springs 39, as will be readily understood.

The cylinder 35 is supplied with steam through a steam supply pipe 42 leading into the rear end of a valve casing 43 formed at the upper end of said cylinder, as best indicated in Figs. 1, 2, 10 and 11. The valve casing 43 is provided with an internal cylindrical bore 44 and a cylindrical slide valve 45 having longitudinal steam passages 46 therein, as shown, and whereby both ends of the steam chamber 44 are Constantly supplied with live steam through the supply pipe 42. Suitable packing rings 47 are provided, as shown, on the slide valve 45 and said slide valve is connected with a control rod 48 extending through the forward end of the valve casing 46. A compression spring 49 is also imprisoned in the forward end of the steam chamber 44 and tends to hold the valve 45 yieldingly in its rearmost position. An exhaust port 50 is arranged centrally in the lower portion of the valve casing 43 as shown. A steam supply port 51 leads from the rear portion of the valve casing into the upper portion of the cylinder 35 and a similar steam supply port 52 leads from the forwanjl portion of the valve easing into the lower end of the cylinder 35. The exhaust port 50 leads to an exhaust pipe 53, as shown. The slide valve 45 is provided with a central valve passage 54 and with end passages 55 and 56, said passages serving, when the slide valve 45 is in its forward position, as indicated in Fig. 10, to supply the upper end of the cylinder 35 with live steam through the port 51 and to exhaust the lower end of said cylinder through ports 52 and 50, whereby when said valve 45 is thus shifted into its forward position, the piston 34 will be lowered in its cylinder and the head 19 lowered into operative engagement with the buck 16. When the valve 45 is shifted into its rearmost position the lower portion of the cylinder 35 will be supplied with live steam through port 52 and the upper end of the cylinder exhaust through ports 51 and 50, as will be readily understood, and whereby the valve 45 serves as a means for fully controlling the operation of the piston 34 and the head 19, as will be readily understood.

The control rod 48 is connected at its forward ends with a control lever 57 fulcrumed at 58 on a lateral extension 59, at one side of a supporting table 60, mounted at the upper end of rocker arms 61 pivoted on a pivot rod 62 extending transversely across the upper forward portion of the frame 15 and supported in a central bracket 63 and in the ends of said frame, as shown. A stud shaft 64 passes freely through the inner end of the lever 57 and engages at its lower end in a slot 65 in the table 60. A pinion 66 is mounted in a guide block 67 loosely resting on top of the lever 57, the stud shaft 64 being fixed to the pinion 66 and extending freely through the guide block 67 and lever 57. Rack bars 68 are slidably mounted in the guide block 67 and en age opposite sides of the pinion 66. These rack bars 68 are pivotally connected at their forward ends with rocker arms 69 on sleeves 70 loosely mounted on the pivot rod 62. At their outer ends the sleeves 7O carry operating rocker arms 71 which are pivotally connected with the rear ends of operating handles 72. By this arrangement, it will be noted, that operation of either of the handles 72 alone will result in a mere idle rotation of the pinion 66 and a corresponding idle retraction of the oppo site operating handle. However, when both of the handles 72 are simultaneously moved inwardly or outwardly, the pinion 66 is held from rotation by the rack bars 68 so that the force applied to the operating handles 72 is transmitted through the stud shaft 64 directly to the lever'57 swinging said lever on'its fulcrum, the shaft 64 traveling in the slot 65 in the table 67 during such operation. Obvi-- ously swinging of the lever 57 operates the control rod 48 and thereby operates the slide valve 45 to control the operations of the piston 34 and the head 19, as explained above. In this Way a simple and eflicient control mechanism is provided which requires simultaneous use of both hands of the operator and thereby prevents the operator from permitting either hand to become caught in the machine between the head 19 and buck 16.

The head 19 is supplied with live steam through a rearward extension 73 connected with a steam pipe 74 leading into a transverse steam head 75 arranged transversely at the rear of the machine. (Io-operating with the steam head 75 is a telescoping steam pipe 76 operating through a stuffing box 77 at one end of the steam head 75 and whereby lateral movements of the head 19 will be permitted as will be readily understood, the pipe section 76 sliding freely in the steam head 75 to permit of such movement. The steam pipe 76 connects with a vertical steam pipe 78 similarly sliding in a steam head 79 through a stuffing box 80, the steam head 79 being supplied with live steam through a steam pipe 81, as will be readily understood, this arrangement permitting of vertical movements of the head 19.

The guide rod 21 and pinion 28 are protected by a guard housing 82 best shown in Figs. 1 and 3. A locking rod 83 is slidably mounted in the housing 82 and in a guide lug 84, as shown. The rear end of the looking rod 83 is arranged in operative relation with a hole or socket 85 in the pinion 30 and whereby when the rack bar 31 is elevated into its uppermost position, the parts may be locked in such position by. means of the locking rod 83 so as to prevent the lateral ironing movement of the head 19 when desired. Under such circumstances the machine will be used as an ordinary pressing machine and without the ironing effect.
