June 17, 1941. F. c. HANSON LAUNDRY APPARATUS Filed Feb. 6, 1940 Patented June 17, 1941 Application February 6, 1940, Serial No. 317,574

7 Claims.

This invention relates generally to new and' useful improvements in laundry apparatus and hasparticular'reference to novel improvements in ironing devices adapted for ironing tubular parts of apparel such as sleeves of shirts, coats or jackets and legsof overalls or trousers and the like. r

I am aware of certain improvements which have heretofore been made in various types of ironers to which 'my invention relates wherein the heated forms were made in relatively movable sectional forms to'accommodate same to various widths of the tubularmembers to be ironed thereby, however, theseironers have been made of relatively complicated parts and provided with mechanisms relatively costly and did not afford the desirable features or advantages which may be secured by my improved ironer.

While these various former devices were to a certain extent adjustable at either or both ends of the elongated heated forms, they were not adjustable in their intermediate portions so as to be form-fitting, thatis, no adjustable means was provided in the intermediate portions of the heated forms affording relatively different exsuch form-fitting tubular partsof various garments. 7

Another feature of my invention resides in the provision of resilient means, preferably foot-operable, for simultaneously moving form-expand ing members transverselyof-the stationary form portion in opposite directions and in degrees of movement corresponding to the general contour of the inner faceof the tubular part, that is, the

form-expansion members are adapted to be movedat spaced portions intermediate their ends different distances responsively to the-diiferent inside widths of the tubular part of the garment at such spaced portions.

Another feature of my invention resides in the provision of relatively flexible elongated members disposed on opposite sides of a stationary heated form which are adapted tobe simultaneously moved outwardly and transversely of the longitudinal axis of the heated form whereby spaced intermediate portions thereof may be moved outwardly different distances from the longitudinal axis. The flexibility of such members adapts same to be slightly bowed in their intermediate portions to thereby lie in graceful curves or lines conformingto the normal formfitting shape of the tubular member to be ironed on such heated form.

A further feature of my invention is found in the provisionof flexible movable elongated members of wire of preferably round cross-section and of a comparatively small diameter positioned on opposite sides of a stationary heated form and movable .in opposite directions whereby same shall function to produce oppositely disposed creases in the sleevesof various kinds of garments or in the legs of overalls, trousers and the like.

My invention consists in the novel combination, construction and arrangement of the parts and members shown in preferred embodiment in the attached drawing, described in the following specification, and is particularly pointed out in the appended claims.

In the illustrations in the attached drawing:

In the illustration, l2 generally indicates a table-like support cornprisinga base [3, a hollow tubular pedestal l4 having a flanged top l5, and a table top It mounted on the flanged top 15.

Each of the twoironing forms is generally in- I8 will apply to either of them as both are of like construction.

The steam heated forms I8 are preferably vertically mounted on the table I2.

Each form I8 is preferably constructed as an upwardly tapering structure having smooth sides, that is, the transverse section decreases progressively upwardly of the elongated structure.

Each form I8 is composed of two separate, like and hollow sections 26 secured together at their base I1, and as by the countersunk screw Each hollow section 26 is formed of preferably segmental cross-section progressively decreasing in area upwardly from its base portion I1, and each sectional is provided with a central recess 21 formed within the outer face of the inner wall 28 and extending longitudinally the full length of the vertical form l8.

When the two sections 26 are secured together, as shown in Figs. 1 and 3, these recesses 21 will form an interior chamber 29 of rectangular cross section extending through the upper and lower ends of the form I8.

The fully closed steam chamber in each form I8 is indicated by numeral 38. Each steam chamber 30 is provided with the steam inlet pipe 20 and a drain connected with the drain pipe 23,

The elongated chamber 29 of rectangular crosssection constitutes a housing for a plurality of spaced operators generally indicated by numeral 3| which are simultaneously operable by a single operating rod 32.

Each of the operators 3I comprises a V-shaped block 33 having a pair of parallel and perpendicularly. disposed opposite sides. 34, of a width slightly less than the inside width of the operating mechanism chamber 30, and a pair of opposite sides 35 disposed angularly downwardly toward the other. Each V-shaped block 33 is slidably mounted on the operating rod 32.

Secured to each of the angularly disposed sides 35 of the V-shaped blocks 33, as by countersunk' head screws 36, is a pair of upwardly oppositely angularly disposed steel leaf springs. 31 having free end portions in sliding engagement with opposite end walls of the chamber 29.-

A set collar 38 is fixed to the operating rod 32 adjacent to the lower end of each V-shaped block 33 and another set collar 39 is fixed to the operating rod 32 a distance above the top of the V- shaped block 33. A spiral spring 40, under normal slight compression, is mounted with one end in abutment with the underside of the collar 39 and the other or lower end in abutment with the top face of the V-shaped block 33.

Pivotally supported below each V-shap-ed leaf spring supporting block 33 on one of the side walls of the chamber 29, as on the end-threaded pins 4|, is a pair of connecting rod operating arms 42 of slightly irregular shape. These arms 42 are preferably made of comparatively heavy material-such as cast or malleable iron, although same might be made of a steel stamping, to insure their normal gravitational positioning with their free slightly curved ends in engagement with the lower ends of the leaf springs 31.

One of the important features of my invention, as generally stated above, resides in the provision of a pair of adjustable and preferably flexible form-expanding members 43 which are positioned on opposite sides of each stationary heated form I8 and are adapted to be simultaneously moved transversely of the longitudinal axis of such stationary form distances difiering in amount or degree at spaced intermediate portions of such form-expanding members 43.

While, as above pointed out, these form-expanding members 43, need not be flexible since same might readily be made of thin rigid steel bars, I find it an additional advantage to construct such members 43 of a comparatively thin round wire of sufficient flexibility to permit it to be slightly bent or bowed at spaced intermediate portions in different degrees of curvature so as to conform to the curvatures of various form-fitting tubular portions of garments such as the sleeve or leg portions. Being of a comparatively small diameter, such form-expanding wires 43, due to their close proximity of and contact with the heated stationary tapered form I8 through their transversely disposed vertically spaced connecting rods 44, are readily maintained heated and are particularly adapted for forming the desirable creases in opposite sides of the tubular garment portions.

It will be observed that these form-expanding wire members 43 extend along the slightly flattened narrow edges of the opposite sides of the tapered stationary heated form I8 from its bottom to its top. V p

The upper and lower ends of each of such wire members 43 are preferably slidably supported and may be bent inwardly of the form I8 to extend into the recesses 45 which are formed inthe upper and lower end portions of the complimentary sectional parts 26 of the form I8, as indicated in Figs. 6 and 7 which show such recess 45 at the upper end of the form I8.

Since most tubular parts of form-fitting garments are made with comparatively long sweeping and slightly curved shapes, the vertically spaced connecting rods 44 may be welded to the form-expanding wire members 43, although a small inwardly disposed pivotal connection between the rod 44 and wire 43 might be employed.

The spacing of the rods and their number may obviously be arranged to suit the designer of the ironing device.

The connecting rods 44 are arranged to extend through the transverse tubular passages 45. Each tubular passage consists of a recess of semicircular cross-section formed in the outer face of the inner wall 230 f each section 26 and the recesses of the two sections 26 are arranged for alignment to form a tubular passage 45 when the sections 23 are secured together.

The inner ends of the connecting rods 44 are brought to close proximity of the straight face portions of the outer sides of the pivoted arms 33.

The operating rod 32, which simultaneously operates all of the operators 3 I associated therewith, extends downwardly through the hollow support I1 and table top I6 for pivoted connection with the foot-operable pedal 45 which is pivotally supported at one end on the sup-port 41 when the pedal is moved down into operative position, to retain same in such operative position.

The hooks 59 are rigidly connected to the ends of rod which is pivotally supported on the upstanding supports 52 formed integrally with the base I3.

Rigidly connected to the center of rod 5| is a foot-releasable pedal 53 which is normally held in raised position by spring 54. A downward movement of the pedal 53 will rock the hooks 50 to thereby disengage same from the pins 49 to thus release the foot pedals 46.

In the modification shown in Fig. "'9 each of the connecting rods 44 has a threaded connection at its inner end with a slightly enlarged rounded head 55 between which head 55 and the face of the end wall of chamber 29 is a coil spring 56 which functions to assist in positively returning the rod 44 into normal inoperative position.

The provision of the springs '56 on each rod 44 is illustrated in 'Fig. 9 as a possible modification although such spring-return of the rods 44 is not necessary for satisfactory operation, since the release of all operators 3| and the removal of the article ironed will readily permit mounting of an unironed tubular garment portion thereon and in such mounting the wires 43 will be moved inwardly against the stationary heated form by such tubular garment portion.

As indicated by the title, the device herein disclosed is particularly adapted for use by laundries for simultaneous form-drying and pressing, or smoothing by means of a heated form, tubular parts such as sleeves of shirts or legs of over-ails or trousers.

In the operation of the device for form-drying and pressing, for example, the sleeves of a shirt, the operator mounts the two sleeves on the forms [3 so that the shirt body will overlie the table top and the enlarged portions of the sleeves adjacent the shoulders are positioned over the lower portions of the steam heated forms. After the sleeves are so mounted the operator then depresses the pedals 46 to thereby cause an outward movement of the form-expanding wire members 43 to efiect expansion of the sleeve forms to stretch, dry, press and crease both sleeves in one operation.

When the pedals 45 are depressed they are automatically locked in such operative position by the spring-pressed hooks 50 which engage over the pins 49.

In the movement of the foot-operated pedals 46 into operative position, the operating rods 32 are moved downwardly and in such movement the rods 32 simultaneously operate all of the operators 3| which move the two form-expanding wire members 43 on each form l8 outwardly in opposite directions.

In such downward movement of the operating rod 32 all of the collars 38 and 39 of the several operators 3| are simultaneously moved downwardly to compress all of the springs 40 to thereby cause by the pressure of such springs 40 a downward movement of the V-shaped blocks 33 with their attached upwardly flared leaf springs 31.

The downwardly moving blocks 33 and leaf springs 37 will cause the loosely pivoted arms 42 to swing outwardly about their .pivot pins 4| to thereby simultaneously push a'll o'fthe connecting rods 44 outwardly of form l8 and thus cause relatively opposite outward movements of the two form-expanding members 43 to properly stretch the sleeves.

-0ppositely disposed creases will be formed in the sleeves by the hot small wire members 43. The thickness or diameter of these form-expand- 'ing and creasing members -43 is preferably about three thirty-seconds of an inch. The diameter of the connecting rods 44 maybe approximately the same as that of the wire members 43 or about one-eighth of one inch. Obviously, the crosssectional form and thickness of the members 43 and rods 44 may be varied.

When the pressing operation has been performed the release pedal 53 is depressed to thereby 'simultaneously release both pedals '46 into upward releasemovement of the rods 32 and all of the operators 3|. 7

It will now be understood that the form-expanding and creasing wire members 43, due to their 'own flexibility and the resiliency-of the leaf springs 31 and that of the springs "40, may readily assume straight or slightly curved formations in their media] or intermediate portions conforming to the form-fitting or tailored shapes of the sleeves or legs of the garment ironed. In other words, the connecting rods 44 may be readily moved relatively different distances by the arms 42 because of the relatively difierent permissible movements of the V-shaped blocks 33 and their operatively associated resilient members 31 and 40.

As above pointed out the pressure applied to wires 43 caused by the removal of the pressed garment and the mounting of another to be pressed on the forms 18 will permit the form- 'expanding wires 43 to be easily moved back against the stationary form l8 into normal position, however, where automatic return of the form-expandingmembers 43 is desired, the construction and spring-actuated connected rods 44 shown in Fig. 9 may be employed.

Various changes and modifications in details of construction and arrangement will become readily apparent to those skilled in the art to which my invention appertains upon perusal of the above specification and attached drawing without departing from the spirit of my invention defined in the appended claims.
