The ironin h ing hereinafter descrlbed and partlcularly differs further from the conventional ironset forth in the appended claims, together ing shoe in that the heating element 11 is so with such variations and modifications therearranged within the shoe as to concentrate the heat largely in the forward edge portion of the shoe so that the edge of the shoe which first engages the material being pressed is the hottest portion of the shoe. This may be accomplished by spacing the heating coils closer together within the forward portion of the shoe as shown in Fig. 3. In pressing pleats, folds and the like, in portions of a garment it is highly important that definite creases be immediately formed in the fabric as the pieces are fed into the space between the presser shoe and roll so that the creases and folds will be formed along the desired lines. This is accomplished by the device of the present invention by delivering the ma terial directly into engagement with the hottest portion of the presser shoe.

Means is provided by which the presser shoe 6 can be instantly disengaged from the roll 4 whenever desired so that the pressure exerted by the presser shoe against the material passing between the roll and shoe can be regulated during an ironing operation. The shoe is moved about its pivotal support by means of actuating connections from a rock shaft 14 extending from the front to the rear of the frame beneath the top 2, the shaft 14 being journaled in suitable bearing brackets 15 secured to the under side of the top 2. A laterally projecting arm 16 is fixed to the shaft 14 adjacent its rear end and the outer end of the arm 16 is connected to the outer end to the bell crank arm 8 by means of a link 17. The shaft 14 has a second arm 18 fixed thereto and extending laterally in the same direction as the arm 16 and to the outer endof the arm 18 there is connected a link 19 which extends downwardly to a pedal 20 which when depressed by the foot of the operator turns the rock shaft 14 in a direction to exert a downward pull on the link 17 to rock the ironing shoe outwardly away from the roll. The shaft 14 also has a downwardly extending arm 21 to which is connected a coil spring 22 which extends horizontally from the lower end of the arm 21 to the inner end of an adjustable rod 23 which is anchored at its outer end to a supporting leg of the frame by means of a nut 24 which may be adjusted to regulate the tension of the spring. The shaft 14 has a second downwardly extending arm 25 fixed thereto and, adjustably mounted on the arm 25, there is a knee plate 26 which is carried by a collar 27 slidable on the arm 25 and secured in adjusted position thereon by means of a set screw 28 carried by the collar. A cam 29, provided with circumferentially spaced notches 30, is mounted on the shaft 14 and cooperates with a spring pressed detent 31 for releasably holding the rock shaft 14 at its opposite limits of movement, in one of which the presser shoe is retained in retracted position and in the other of which it is retained in engagement with the roll. The

presser shoe is yieldingly pressed against the roll 4 by means of the spring 22, but in order to maintain a proper feed of the material it may be desirable to partially relieve the pressure at times during an ironing operation. 5

This the operator can do by pressing laterally with his knee against the knee plate 26 or by exerting a pressure with his foot on the pedal 20, thereby exerting a torsional thrust on the rock shaft 14 in opposition to w the thrust of the spring 22, taking a portion of the thrust of the spring with his knee or foot so that the presser shoe will be yieldingly pressed with a lighter thrust against the ironing roll. The operator can thus readily control the amount of pressure exerted on the work while it is passing beneath the presser shoe, and if at any time the work begins to move out of proper position, by H simply increasing the pressure of his foot or knee can instantly disengage the presser shoe.

The ironing roll is driven by an electric motor 32 which is preferablya variable speed motor provided with a suitable control by which the speed may be varied as desired during operation of the machine. The drive from the motor 32 through the ironing roll 4 is through a suitable worm gearing in housing 33 which drives a belt 34 extending to a pulley 35 supported by a bracket 36 depending from the top 2. Mounted coaxially alongside the pulley 35, there is a second pulley 37 which is driven from the pulley 35 through a clutchof conventional design. A belt 38 provides a driving connection from the pulley 37 to a pulley 39 011 an end of the shaft of the roll 4. Pulleys 35 and 37 are engaged and disengaged by a suitable clutch shifterlever 40 pivoted to the bracket 36. The lever 40 is provided with a projecting brake arm 41 which extends over the pulley 35 and engages with a cylindrical portion 42 of the pulley 37. The lever 40 has a laterally ex-- tending arm 43 which is connected by a link 44 to a foot pedal 45 so that the operator may, by means of the foot pedal, instantly disengage the clutch at any time and simultaneously apply the brake to stop the rota- The ironing of portions of garments which have folds, pleats or the like without previously basting or priming the folds or pleats, requires that the article be correctly folded or pleated as it enters between the presser shoe and ironing roll. The operator can make the necessary folds or pleats in the fabric on the feed table 46 but it is difficult for the operator to hold the fabric to the proper form while it passes over the top of the ironing roll and into engagement with the presser shoe. This would also necessitate holding the fabric with the hand while it is passing over the top of the roll which would bring the hands of the operator uncomfortably close to the hot presser shoe, with the danger that the operator might get his fingers caught between the shoe and roll. This difficulty is avoided in the machine of the present invention by providing a small roller 47 extending the full length of the ironing roll and engageable with the top of the ironing roll between the feed table and ironing shoe. The roller 47 is mounted for vertical movements toward and away from the ironing roll and is preferably interconnected with the shoe shifting mechanism in such manner that it is engaged with the ironing roll as the presser shoe is moved away from the ironing roll and is shifted out of engagement with the ironing roll as the presser shoe is moved into engagement with the ironing roll.

As herein illustrated the roller 47 is journaled in the forward end of a pair of arms 48 which are fixed to the horizontal shaft 5 upon which the ironing shoe is pivoted. The shaft 5 is provided with a rearwardly extending arm 49 which is connected by a link 50 to an arm 51 fixed to the shaft 14 and extending to the side of the shaft 14 opposite that upon which the shoe actuating arm 16 lies, so that the movement of the roller actuating link 51 is always in a direction opposite that of the shoe actuating link 17 With the ironing shoe disengaged from the roll and the roller 47 engaging the top of the ironing roll, the op-' erator may fold the piece to be ironed to the proper form on the feed table 46 and feed the piece forwardly onto the ironing roll 4 and beneath the roller 47. The roller 47 serves to hold the piece to be ironed against the top of the roll to retain the folds which have been made therein by the operator. When the forward edge of the piece has been advanced to a position where it will be engaged by the forward edge of the ironing shoe, the ironing shoe is shifted into engagement with the roll, the roller 47 is lifted out of engagement with the work.

It will be apparent that the device of the present invention provides a simple and inexpensive ironing machine which can be effectively used for pressing or ironing folds, pleats or the like in parts of garments during the process of manufacture without the necessity of hand basting or pinning the fabric prior to the pressing operation and in which means is provided to hold the pieces to be pressed flat against the roll while being delivered to the heat and pressure applying element, thereby very greatly lessening the danger of the operator injuring his hands in feeding the pieces beneath the heated presser shoe.

Furthermore, it is to be understood that the particular form of apparatus shown and described, and the particular procedure set forth, are presented for purposes pf explanation and illustration and that various modifications of said apparatus and procedure can be made without departing from my invention asdefined in the appended claims.
