PORTABLE IRONING MACHINE.

Application filed January 23, 1925.

To d yelio/nt -z't may comin/'fn A Be itl nown that I, Mic-in HEDGLON, a citizen of the United States, residing at Syracuse, inthe county oi Onondaga and State of New York, have invented certain new and useful Improvements in Portable Ironing "Machines, of which the following is a specification.

This invention relates to improvements in ironing machines, designed particularly for household use, and has for its object to provide a novel, simple Yand light machine,A

smoothing of the articles, as they are moved over a heated surface of thel shoe. In the present case, the ironing roll constitutes the driven member of the machine, which is rotatable in a fixed horizontal plane, by an electric motor, and the shoe is disposed directly bcncathand substantially concentric to the roll. rI he rear side of the shoe is shown pivoted to the frame, in a manner to allow the shoe to be moved bodily, as wcll as to twistor rotate in a horizontal plane relatively to the axis of the roll. The forward side of the shoe is allowed a certain range of adjustment towards and away from the roll in a vertical plane, for facilitating applying and adjusting the articles, by means of an eccentric mechanism, which is controlled manually by a lever, and with the latter is associated adjustable tension means, by which a variable ironing pressure may be effected and maintained. The ar? rangement of the pivot and eccentric mecha` nisms is such that, any inequalities of the ,ironing roll itself, as well as any variations in the thickness of the articles to be ironed are taken care of by the flexing of the tension means, and also by the iioatable nature of the shoe, due to the peculiar arrangement of the shoes pivot. A particular object of this invention is to provide an ironing machine of the class, which is arranged to be operated and controlled by a person who may sit facing the frontside of the machine, instead of having to stand and lean over the machine, as heretofore. And a further ubicct is to provide an ironing machine Serial No. 4,262.

whereby certain portions of the articles, such for example, as the cuffs and collar-bands 0f shirts, as well as circular margins or other portions of dresses or skirts', and the like, may be ironed at the remote open end of the machine, without requiring the whole garment to be passed or fed through the machine.

This invention relates particularly to improvements in the ironing machine shown and described in my pending application filed September 25, 1924, Serial No. 739938.

The various features and parts of the invention will be understood from the detailed description which follows and by reference to the accompanying drawings, in which- Figure 1 is a topv plan view of the complete machine. Fig. 2 is a partial front side elevation and a partial central vertical longitudinal section; the, latter being taken ou lin-e 2-2 of Figi l. Fig. 3 is an enlarged detail view of the clutch that controls'the ironing roll. Fig. 4 is a front end elevation with the cover of the gear casing removed; showing the gear train that operates the ironing roll; also showing the eccentric mechanism by which certain movements of the shoe are controlled. Fig. 5 is a broken vertical cross-section taken on line 5--5 of Fig. 2; showing the shoe lowered from the ironing roll. Fig. 6 is a similar view showing the shoe in the ironing position. Fig. 7 is a top plan view of the ironing roll and the slices; showing the shoe twisted horizontally at an angle to the axis of the ironing roll. And Fig. 8 is a rear-end elevation of the machine.

In the drawings, 2 represents a common wooden base, upon which the combined :ironing and driving mechanism is rigidly mounted, and rendered easily portable, as one part. One of the ironing members preferably consists of a heavily padded ironing roll 3, which is driven by a motor 4, the said roll being supported for operation in a fixed horizontal plane, by means of spaced rigid brackets 5 and 6. The other member comprises a trough-like ironing shoe 7, substantially the same length as the roll 3, but being broader and normally projecting beyond the opposite sides of the roll, as shown in Figs. 1, 4, 5, G and 7. The trough 7 of the shoe is normally disposed concentric to the roll 3, and may be 'tinted longitudinally, as shown at 7X in Fig. 5, for increasingthe frictional area of the ironing surface, as

ioo

y sa

well as for ventilating the shoe, by allowing the vapor from the damp articles to escape at the opposite ends of the shoe.

The roll 3 consists of a hollow tubular body 3 having normally open ends, in which are permanently disposed concentric heads 3, which are bored out centrally to receive similar shaft-sections 8 8', the latter constituting the axis of the roll 3, the said shafts preferably being rigidly secured to the heads 3, bymeans of pins 8a. The roll 3 is externally covered by a relatively thick layer of padding, 3b, for suitably cushioning the roll, as shown in Figs. 2, 4, and 6.

The top portion of the bracket 5 comprises a hollow body 5', in which housed a train of gears, by whichthe power of the motor 4 is transmitted to the roll 3. The brackets 5 and 6 are provided with bottom flanges through which bolts 5a are driven, for rigidly securing the brackets to the base 2. The gear-train consists of a worm 9, which is rigid on a shaft 9, the latter being' journalled in bearings 5". Upon the shaft 9 is mounted one member 10, of a clutch, the other member 10 of the clutch being rigid on shaft 4 of the motor.

The worm 9 meshes and drives a relatively large gear 12, which is journalled on a stationary shaft 12', the latter being supported by the casing 5, and also by the cover 5 of the casing, as best seen in Fig, 2. The gear 12 Supports and drives a pinion 13, which meshes and drives a relatively large spur-gear 14, the latter gear being arranged concentric to the roll 3, as shown in Fig. 4. The gear 14 is preferably loosely mounted on the shaft 8, upon which it may idle, when the roll 3 is stationary. The gear 14 is arranged to be driven constantly by the motor, and the roll 3 is driven during the ironing operations by a clutch c, which comprises the outer end of the hub 14 of gear 14, and the corresponding end of an aligning sleeve 8b, which is keyed to and is slidable on the shaft 8, as shown at 8C, in Figs. 2` and 3. The sleeve 8b is journalled in a bearing 5e of the cap 5c, and its outer end is formed with a liob 8d, by which the sleeve may be moved axially on shaft 8 relatively to the roll 3, for Starting and stopping the said roll.

The rear edge of the shoe 7 is pivotally supported by a stationary rod or shaft 15, which passes loosely through, and plays in slots 15 formed in flanges 15a, of the opposite ends of the shoe, as shown in Figs. 4, 5 and G. By this construction and arrangement the shoe 7 may be moved forwardly and backwardly as well as circularly on the rod 15. The ends of the rod 15 extends beyond the ends of the shoe and are disposed rigidly in, and are supported by, integral arms or lugs 5i and 6 of the brackets 5 and 6, as shown in Figs. 1 and 4. The

upper rear portion of the shoe is formed round, for facilitating the discharge of the ironed articles. The forward edge of the shoe is fitted with a similar shaft or rod 17, Whose ends also project beyond the ends of the shoe, and upon these projecting ends are mounted respectively a crank 17 and an operating lever or crank 18, as shown in Figs. l, 4, 5 and G. The crank 17 and the lever 18 are formed with similar perforated lobes, as 17a and 18 (see Figs. 2 and 4), which are engaged by the upper hook-endsof guide-rods 19-19. Both of the said rods extend downwardly from the lobes and are loosely inserted through perforated extensions 5X and 6 of the brackets and G. The rods 19--19 are similarly threaded intermediate their ends to receive adjusting nuts 20. Between the nuts 2O and the said extensions are disposed similar coil compression springs 21, through which the said rods pass, the said springs being disposed between washers 21-211, as best seen in Fig. 4, in which the full lines show the lever 18 depressed and the springs slightly compressed fo-r lifting, and for holding the forward side of the shoe 7 in the ironing position, shown in Figs. 4 and 6. When the lever 18 is moved to the dotted position shown in Fig. 4 and the full line position shown in F ig. 5, it effects the lowering' of the forward side of shoe 7 away from the roll 3, by gravity, as shown in Fig. 5. The perforations of lobes 17a and 18 are so disposed that When lever 18 is lowered to the full line position shown in Figs. 4 and G, the points of pivotal'contact of the rods 19-19 are moved inwardly past, or eccentric to, the axis of shaft 17, and prevents the accidental release and lowering of the shoe, ,until vthe operator swings the lever 18 upwardly, as to the dotted position, shown in Fig. 4 and the full line position shown in Fig. 5. The nuts 2O are employed 'for regulating' the tension of the springs 21,

for lifting and for sustaining the load of the relatively heavy shoe, as well as for creating the additional pressure of the shoe against the undersidero-f the roll 3, required for performing the ironing work. When the lever 18 is swung upwardy to the dotted or release position, the rods 19-19 are also lifted thereby sutliciently to relieve the pressure of the nuts against the springs 21. Thisallows the forward edge of the shoe 7 to gravitate away from the roll 3, as shown in Fig. 5; the extent of this lowering of the shoe being limited by the spacing of the shaft 17 and the perforations of the lobes 17a in which the rods 19-19 are pivoted. This releasing of the lever 18, also allows the springs 21 to relax and lengthen, but the said springs still continue to support the shoe, when the latter is in the position shown in Fig. 5, and said springs therefore tend to regulate or limit the gravitative travel of said shoe. The

.lever 18 is provided with a rearwardly facing lug 1S?, which is arranged toengage a screwor stud 7 carried by 'the shoe, for f v l ydurable and light, and may be produced arresting the releasing movement of the lever, as shown 1n Fig. gl., The top` face of the forward edge-of the shoe 7 is normally flat, and to the said edge is detachably applied, preferably in the same plane, a table 22,' upon which the unironed articles may rest while being adjusted and fed-towards the roll 3, as shown in Fig. 6. The table 22 is spaced from the shoe by asbestos or other heat resisting spacers 22, which tend to keep the table cool, and the table is secured to the shoe by bolts 22a, as shown in Fig. t.

The medial longitudinal portion of the shoe 7 is preferably hollow and comprises a heating chamber 7d, in which is disposed the electric heating element consisting of a horse-shoe shaped part 28, as shown in Figs. 1, t, 5 and G, and the said element may be supplied with current by wires 23 and 23a. rllhe heating of the shoe may be controlled by any suitable 'switch or controlling means (not shown) in a well-known manner. The current for the motor 4, which drives the ironing roll may also be controlled in any usual manner. The arrows in Figs. 4, 5 and indicate the direction of rotation of the roll 3.

In Fig. 7, the shoe 7 is shown at a slight angle relatively to the longitudinal axis of the roll 3, and indicates the twisting or movement of the shoe in a horizontal plane. '.lhis automatic floating action of the shoe will be appreciated, when it is understood that at the instant a piece of cloth, as a, is fed into the machine, as shown in Fig. 6, the

shoe 7 is shifted forwardly on rod 15, until4 the rear portion of the trough makes contact with the right underside of th-e roll. lf the article is the same thickness throughout, the shoe and the roll will be maintained in substantially normal concentric relation, as shown` in Fig. 1. YWhen however, the article is thicker at, say the left margin, than at the right, the extra thickness at the one end will first cause the corresponding portion of the shoe to be forced forwardly and downwardly, while the opposite end will be practically unchanged, and then when the article reaches thel rear side of the trough 7', the thickened end of the article will cause the corresponding portion of the shoe to be moved rearwardly on rod 15, as shown at 7e in Fig. T. These forward and backward movements of the shoe, whether the latter is moved bodily, or whether one or the other end only is shifted, is effected by the play of the shaft 15 in the horizontal slots 15 of the shoe, rl`his floating action of the shoe during the ironing operations is futrther facilitated, by the flexible or resilient nature of the supports 21 at the forward side of the shoe, as explained.

My ironing machine is extremely simple,

at comparatively low cost. The novel arrangement and disposition of the floating shoe, the controlling lever and clutch, and the adjustable tension means, by which the raising and lowering of the shoe is effected, andy also by which the ironing pressure may also, be regulated at will, enables me to provide a light portable device of the class, which may be readily moved from place to place, and may be mounted upon a table, or between tables, or chairs, or other supports during the ironing operations, the said machine being arranged particularly for operation by a person while seated at the front side of the machine, within convenient reach of all of the controlling and operating means.
