UNITED STATES PATENT OFFICE This invention relates to new and useful improvements in electric pressers and ironers.

It is one of the principal objects of my invention to provide a portable electric presser and 4 ironer which can readily be set up and attached to a source of electric current for pressing and ironing garments and other'fabrics. Its compactness, efficiencyand portability are qualities that commend themselves to a person who oc- 10 casionally'presses trousers and other articles of clothing at home or elsewhere. It is equally well adapted for ironing various fabric articles, and

- may be used to good advantage by a press shop in the pressing of suits while one waits.

' 15 It is one of the particular objects of my invention to discharge steam through a heated bed to dampen the fabrics being pressed or ironed.

If the bed were not heated, the steam would condense and pass'through the discharge orifices as 20 water, nor would the bed itself be hot enough for an eflicient pressing or ironing operation. 1

It is another object of my invention to provlde lever means for-raising the roll above the bed to a position from which it may be easily 25 tipped back to permit the insertion of the fabrics to be pressed or ironed,;between the roll and the bed.

. Pressing and ironing with my device is an easy, quick and economical operation, and one which 30 insures excellent results.

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.

In the accompanying drawings illustrating one 5 form of embodiment of'my invention, Figure 1 is a side view of my pressing machine. Figure 2 is a longitudinal-sectionalv view taken through the machine. Figure 3 is a transverse, sectional view taken on the line H of Figure 2. Figure 40 4 is a transverse sectional view taken .on the line H in Figure 2. Figure 5 is a detail view of the dryer tube. Figure 6 is a detailed view of the heated bed. Figure 7 is a detail view of the inner end of the roll bracket. And Figure 8 is a detail 4 view of the support.

Referring now to the accompanying drawings for a detailed description of my invention, the numeral I designates a rotatable pressing roll having thereon a conventional fabric covering 2.

50 The roll I is mounted upon a shaft 3 joumalled in an outboard bearing 4, a center bearing 5 and an inner bearing 6. The bearings 4, 5 and 6 are cast integral with a bracket I, having at its inner end a suitable motor mounting pad 2. At its 7 55 outer end the bracket-is formed with an inverted circular portion 2 above the roll I. (See Figures 2.,3and4).-

Supported below and in alinement with the axis oi'the roll I is astationary bed Ill. The

central portion of the face of the bed I is formed to the contour of the roll I, while its longitudinal edges II, II are formed downwardly to facilitate entrg) of the material to be' presse d. (See Figure AsshowninFigur'es2,3and6,thebedlllis 10 formed with a series of longitudinally positioned tubes l2, whose open ends are received within aninlet header I! at one end of the bed, and an outlet header H at the outer end thereof, whose inner wall M is apertured to receive the tube ends. This assembly of tubes l2 and headers II and I4 are then cast enblock to form the bed. As shown in Figure 6, the center tube I2 is slightly longer than the'remainder of the tubes, having its outer end permanently closed within the header ll and its inner end provided with a needle valve llbywhich steam is admitted to it from the header II.

. Positioned below the bed l0, and attached thereto, is a cylindrical boiler l6 of substantially the length of the roll and bed. This boiler is preferably formed from steel tubing having welded I convex heads I! and I8. Asshown in Figure 2, the boiler is positioned with its axis horizontal,

and has secured in the bottom thereof a dryer tube ll. This tube, as shown in Figures 2, 3 and 5, is elliptical, having open ends which are pressed together and welded to exclude water therefrom. Communicating with the dryer tube l 9, and attached to the outer end thereof, is a wet steam inlet tube 2|. The upper open end 22 of this tube projects into a filler neck 22, welded to the outer head I! of the boiler It. When this filler neck 22 is closed by a suitable cap 24, steam will enter the dryer tube I 9 through the inlet tube 2| (See 40 Figures 2,3and 5).

Communicating with the dryer tube l9 at its inner end, is a dry steam outlet tube 25 whose upper end is secured to, and discharges into, the inlet header it. when the dry steam enters the header ll, it flows through the tubes l2. except the center one thereof. The steam thus entering the tubes l2 will maintain the bed at a relatively high temperature. The condensation from the steam flowing through these tubes, will flow into the header I4, and, through a small orifice 26, will return to the boiler. I

When a garment to be pressed is passed be- .tween the roll I and the bed It, the valve I5 is opened to admit dry steam from the header I2 to the center tube l2. This, tube is provided with a plurality of small orifices or Jets 21 extending through the center of the bed l and below the roll I. The steam thus released through these jets in the heated bed will not be readily condensed thereby, but the moisture from the steam will sufficiently dampen the cloth to aid the pressing thereof.

Positioned beneath the boiler l6, and formed to the contour thereof, is an electric heating element 28 of conventional form, and having terminals 29 for connection with an electric circuit (not shown). Surrounding the heater element 28 and the boiler I6 is a heat-retaining insulation 30 such as asbestos and encased in a metal apron 3| that extends upwardly to the bed l0 and to which it is secured.

Rotation of the roll I is effected by a motor 32 secured to the pad 8. Mounted on the motor shaft is a worm 33 in mesh with a worm gear 34. The worm gear 34 is secured to a short shaft 35 journaled in bearings 36, 36 integral with the bracket 1. Also attached to the shaft 35 is another worm 31 that drives a worm gear 38 keyed to the shaft 3.

'I'he'means for raising the roll structure above the bed to permit the insertion of the garments to be pressed or ironed, will now be described. The bracket 1; at its inner end and adjacent the bearing 6, is formed downward to provide two oppositely disposed side flanges 39, 39 joined by a transverse web 40. This web projects downwardly below the bearing 5 and has formed on its outer face at its marginal edges flanges 4|, 4|. (See Figures 2, 3 and 7) v The bracket 1 is slidably received between the upper forked ends 42, 42 of a support 43. Secured to the inner face of each of the forked ends 42, 42 is a roller 44 freely mounted on a stud 45. Below the rollers 44, the forked ends have formed. on their inner and oppositely disposed faces, parallel ribs 46 and 41. Projecting transversely through the forked ends 42, 42, and below the ribs 46 and 41, is a shaft 48 to which spaced lever arms 49, 49 are secured. To the outer ends of the arms 49-49, links 50-50 are pivotally connected. At their upper ends these links 50-50 are pivotally secured to the lower ends of the ribs 4|, 4|.

On the outer faces of the ribs 4| 4| I have provided'rollers 5|, 5| that are received between the ribs 45, 41. When so positioned between these ribs, the bracket 1 is permitted a vertical travel when the shaft 48 is rotated to move the links 50 vertically.

Formed on the oppositeouter faces of the side flanges 39, 39 are short parallel ribs 52 and 53 between which each roller 44 passes when the bracket is lowered. (See Figures 2, 4, '7- and 8).

When the bracket 1 is raised by the rotation. of the shaft 48, the ribs 52 and 53 on the opposite flanges 39-39 will be raised above the rollers 44. This will permit the bracket 1, roll I and associated mechanism mounted thereon to be rotated clockwise as viewed in Figures 1 and 2. When the bracket is thus rotated, it will revolve about the rollers 5|-5| maintained between the ribs 46 and 41, thus permitting the roll structure to be easily tipped'backa suflicient distance to allow the'ga-rment to be inserted between the roll and the bed. For the purpose of lowering the roll I to press the garment against the face of the bed l0, the shaft 48 is rotated counterclockwise as viewed in Figure 2. The ribs 39 and 40 will then engage the rollers 44, 44 to maintain the .roll and bed in flrm engagement with each other through out their lengths during the pressing or ironing operation.
