the same pressure and tension both lengthwise and transversely of the article, avoiding any dis- 10 tortion thereof and imparting thereto a desirable smoothness and sheen. Hand ironing thus produces a noticeably better finish to the articles than it is possible to accomplish by machine ironing, as usually practiced, but is open to the objec- 20 tion that it involves more time and labor than ironing by machine.

My invention is directed primarily to the provision of an ironing machine which, in operation, closely approximates hand ironing and imparts to the articles that smoothness and sheen characteristic of articles ironed by hand. Broadly, it is an object to provide an ironing ma-,

chine having two cooperating ironing members, one of which is a rotating roll, movable into and out of cooperating relation and capable of relative reciprocation lengthwise of the roll, the roll being driven by a motor and means being provided to eiiect the desired relative movements of the members. A further and more specific object is to provide simple and efficient means for moving a cooperating shoe lengthwise of the roll, in cooperating relation therewith. It is also an object to provide means for optionally stopping relative reciprocation of the ironing members in predetermined relation one to the other. Further objects and advantages will appear from the detail description.

I have illustrated my invention, by-way of example, as embodied in an ironing machine which is, in general, similar to that disclosed in Patent No. 2,054,631, issued September 15, 1936, to Ru dolph W. Janda, for Ironing machine. Themachine comprises a suitable stand .having a top bed plate 9 supported by depending legs ID. A main gear housing I l, closedat its outer end by a removable cover plate I2, is appropriately mounted upon bed plate 9, at one end thereof, and extends downward therethrough. -A sleeve I3 is formed integrally with, and extends upward from, bottom wall l4 of housing I I. v

A worm gear housing I5, appropriately secured to and depending from housing II,, is provided with a collar l6 aligned with a depending bearing boss I1, the latter receiving the lower end portion of a shaft section l8, which passes upward through collar IS. A worm wheel l 9 is se-' cured upon shaft section I8 and meshes with a worm 20 fixed on a shaft 2| rotatably mounted -in housing 15, the latter shaft being driven, through a flexible coupling 22, by an electric motor 23 suspended from bed plate 9 by hanger brackets .24.

Shaft section l8 passes upward through a bushing 25, mounted in sleeve l3 with its lower endcontacting the upper end of hub I 9a of worm wheel I 9. Bushing 25 extends above sleeve l3,

, through an eccentric and clutch assembly designated generally by the reference number 26. The assembly 26 is similar to the eccentric and clutch assembly disclosed in the above identified patent to Rudolph W. Janda and in .Patent No.

1,867,839, issued July 19, 1932, to Rudolph W. Janda, and need not be illustrated, nor described here in detail, abrief description thereof being sufiicient.

Assembly 26 comprises a member 21, loose on .bushing 25, having a depending eccentric 21a seating at its lower end upon the upper end of sleeve I3. Suitable means is provided 'for clutching and declutching member 2'! to and from shaft section l8. This clutch means is controlled by a,

' from shaft section I8.

trip finger 28 pivoted to the front-wall 29 of gear housing H and normally held in operative position. Finger 28 is connected, by a rod 30, to an arm 3| secured upon a pin 32 loosely mounted through a lug 33 extending inward from upper portion 29a of front wall 29 of housing II. An angle lever 34 has its lower end secured upon pin 32, extends through a slot 35 in wall portion 29d, and is provided at its outer end with a head or knob 36. Lever 34 normally is held in its outer position by a coil wire spring 31 disposed about pin 32, with one arm engaged beneath arm 3| and its other arm extending across the top of lug-33, in rear of lever 34 and effective as a stop for limiting outward movement thereof. Spring 31 also serves normally to hold trip finger 28 in normal position, effective for declutching member 21 from shaft section l8 and maintaining it declutched.

When lever 34 is moved inward a short distance, trip finger 28 is moved into inoperative position, releasing the clutch means, which is spring actuated, thus clutching member 21 to shaft section |8 for rotation therewith. Lever 34 is moved inward but momentarily, and is then released, returning trip finger 28 to operative position. Rotation of member 21 with shaft section l8 continues during a predetermined portion, about of the ensuing rotation of shaft section I8, at which time an element of the clutch contacts finger 28 and member 27 is declutched In this manner member 21 is clutched to shaft section I8, turns therewith to a predetermined extent, and is then automatically declutched therefrom. The particular clutch means employed is not of the essence of my invention, though I preferably employ the clutch means disclosed in Patent No. 1,867,839, above referred to. Suffice it to state that suitable means is provided for optionally clutching member 21 to shaft section H! for rotation there-. with to a predetermined extent, and declutching member 21 from the shaft section when it has been turned to the desired extent.

Shaft section l8 is'disposed below and coaxially with an upper shaft section 38 rotatably mounted through a relatively thick rib 39 extending from the inner end Wall of gear housing Shaft section 38 is provided, at its lower end, with a reduced squared stud 38a which fits into a corresponding bore in the upper end of a coupling member 39. Shaft section I8 is -provided, at its upper end, with a reduced squared stud |8a which fits into a corresponding bore in the lower end of member 39. In this manner, the two shaft sections are coupled together-for rotation as a'unit.

An ironing roll 40, provided with a suitable pad, extends from gear housing inward over bed plate 9 there-above and parallel therewith. Roll 46 is mounted for rotation about its axis, and is secured to a shaft 4|, extending into gear housing II and appropriately mounted for rotation. Conveniently the roll 40 and shaft 4| are mounted and secured together in the manner disclosed in the two above identified Patents No. 1,867,839 and No. 2,054,631. The particular manner of mounting roll 40 and shaft 4|, and connecting them together, is not of the essence of my invention, and need not be set forth in greater detail. Sufiice it to state that the roll and the shaft are rotatably mounted and connected together in an appropriate manner.

Roll shaft 4| is driven, as desired, fro-m shaft section 38 through'a change speed gearing assembly indicated generally by the reference number 42. The assembly 42 is similar to that disclosed in Patent No. 2,054,631, and need not be described here in detail. It has associated there-. with suitable control means whereby shaft 4|, and consequently roll 40, may be driven at either one of two speeds, or rotation of the roll may be prevented, as desired. The control means is operated by a control rod 43 mounted for turning movement through a boss 44 at the bottom of upper portion 29a of front wall 29 of gear housing Rod 43 also extends through and projects outward beyond a plate 44a seating upon the outer face of boss 44, suitably secured thereto and extending downward therefrom to the upper surface'of'bed plate 9. An operating handle 46 is secured upon the outer end of rod 43, the inner end of which is connected, by a universal connectlon 41, to the forward end of a .turnably mounted control member 48. Means is also provided, comprising a two-part control lever 49 and a cooperating eccentric 50 rotatable with member 21, for automatically enabling and disabling the drive between assembly 42 and roll shaft 4|, in accordance with predetermned turning of the latter. The variable speed driving means and associated control means, referred to, are fully disclosed in Patent No. 2,054,631 and need not be described in greater detail here. If desired, any other suitable means may be provided for driving the roll shaft, such, for example, as the means disclosed in Patent No. 1,867,839 or in Patent No. 2,026,345, issued December 31, 1935, to Rudolph W. Janda, for Ironing machine. It will be seen, from what. has been said, that the shaft sections l8 and 38, together with coupling member 39, constitute a unit or shaft and that this shaft has appropriate driving connection to the roll for driving or rotating the latter from the motor 23. The ironing machine illustrated and so far described, is, in general, similar to that disclosed in Patent No. 2,054,631.

Gear housing H is provided, at its rear inner ,53, the bore of which is coaxial with and of less diameter than recess 52, providing a shoulder 54 at the inner end thereof. An elongated tube or sleeve 55 is mounted at its outer end in boss 53, extends therefrom along bed plate 9 in close proximity thereto and parallel with roll 40, and has its inner end portion secured in a bracket 56 (Figs. 1 and 2) in an appropriate manner, as by a set screw 51 (Fig. 3), which bracket is bolted or otherwise suitably secured to bed plate 9. A shoe operating shaft 58 extends through bushings 59 mounted in the ends of sleeve 55 (Figs. 3 and 6), and is mounted therein for axial reciprocation and rocking movement about its axis. Shaft 58 extends through the outer end of sleeve 55 and boss 5| into gear housing II, as shown in Figure 6, and also projects through the inner end of sleeve 55 a considerable distance beyond bracket 56, as shown in Figures 1 and 2.

- A shoe operating armQ60 is suitably secured, as by means of a pin 60a, on the inner end of shaft 58, and is straddled by a bifurcated shoe supporting arm 6|, loosely mounted at its lower end on shaft 58 and confined-against relative movement lengthwise thereof by arm 60. Means, including an emergency release lever 62, is provided for normally coupling the arms 60 and 6| together for movement as a unit. An ironing shoe 63, conveniently heated by electrical resistance elements contained therein, is mounted upon the upper end of arm 6| for movement therewith.' This shoe is of known construction and has a concaved ironing or operating surface conforming in transverse curvature and in length to the cooperating'surface of the roll 48. It will be clear that the shoe 63 is mounted on shaft 58 and connected thereto for movement therewith, when the arms 68'and 61 are coupled together. The arrangement of the arms 68 and 6| and the associated coupling-means and the shoe is similar to that disclosed inPatent No. 2,026,345. It is not essential to my invention, however; that this particular arrangement be used, and any other suitable means may be provided for supporting the shoe and operatively connecting it to its associated operating shaft.-

An arm 64 (Figure 4) is secured by a pin 66a,

(Figure 6) upon the outer end of shoe operating shaft 58, within gear housing ll, and extends downward therefrom. The lower end of arm 64 isconnected, by a universal connection 65, to the rearward end of a connecting rod 66 provided at its forwardend withan eccentric strap 61 fitting about eccentric 21. Turning of eccentric 21 to predetermined extent, into one position, turns shaft 58 about its axis in one direction, and turning of the eccentric from that position through 180 into its other position, turns shaft 58 about its .axis inthe other direction. In this manner eccentric 21 ,serves to turn shoe operating shaft 58 about its axis in alternately opposite directions and to predetermined extent, efiective for moving the shoe 63 to the roll 48 in cooperating relation therewith and moving the shoe away from the roll out of such cooperating relation.

Shoe operating shaft 58 may also be 'reciprocated axially, for reciprocating the shoe length- -wise of the roll. A lever 68 is pivoted. at its midportion for movement abouta vertical axis, on a stud 69 screwedinto aboss 18 integral with wall H of gear housing I I as shown in Figure 4. At its rearward end lever 68 bears upona bearing ball 12 (Figure 6) seated in a corresponding recess in the outer end of shaft 58. A coil compression spring 13,' mounted about shaft 58, is.

confined under compression between shoulder 54 and the upper end of arm 64, and yieldinglyurges shaft 58 outward. Coupling member 39 is provided at its mid-portion with an eccentric I4 fixed thereto, conveniently formed integrally therewith. Lever 68 carries, a shdrt distance from its forward end, a roller I5, mounted for rotation about a vertical axis and bearingupon the operating surface of eccentric I4, which rotates in a clockwise direction, as indicated by the arrow in Figure 6, in the rotation of the roll a drive shaft, comprising sections l8 and 38 and the coupling member 39. The cam 14 and'lever 68 cooperate'to limit outwardrnovement of shaft 58 and'to move the latter inward-in opposition to spring 13, aswill be clear from Figure 6. In this manner shaft 58 is reciprocated axially, as indicated by. the double-headed arrow a, reciprocating shoe 63 lengthwise of roll.

48. The provision of the universal connection 65, in conjunction with the ability of eccentric;

strap61 to turn slightly about eccentric 21, if necessary, eliminates possibility of binding of parts incident to reciprocation of shaft .58.

, In Figurel shoe 63 1s shown in the position which it occupies when shoe operating shaft 58 has been moved by spring 13, under control of lever 68 and eccentric 14, into its outermost po- 'Figure 2 shoe 63 is shown in its other extreme position, into which it is moved in the direction indicated by the arrow a incident to corresponding movement of shaft 58. It will be noted that the ends of shoe 63, in.t he latter position thereof, are flush with the ends of the roll, so that the operating surface of the shoe is coextensive lengthwise with the operating surface of the roll, for a purpose presently to be described.

In some cases, as when ironing pleated garments or certain fabrics, it may 'be desirable not to reciprocate the shoe. Accordingly, Lhave pro- Vided suitable means to that end. Lever 68 is provided, at its forward end, with an upwardly projecting head 68a the outer face'of 'whichis "convexed in plan, as shown in Figure 4. Head the latter projecting forward from wall 29 of gear housing H, below and adjacent boss 44. Rod 11 is provided, at its outer end, with an operating knob 19 and, in the ,portion thereof operating through boss 18, with two circumferential grooves so and 81. A locking ball 82, yieldingly'urgedupward by a'coil compression spring 8 3,disposed within bore 84 in boss I8 and confined between the ball and a screw plug 85 closing the-lower end of the bore, is disposed to engage into groove 88 in the inner position of rod 11, and groove 8| in the outer position of this rod.

Bore 68b.,is so disposed as tobe aligned with stud 16 when head 68a of lever 6-8 is in its outermost position, at which time the point on the circumference of eccentric [4 most remote from the axis of the roll drive shaft is in contact with roller 15 and shoe operating shaft 58 isin its innermost position, shoe 63 then being in the position shown in Figure 2. In order to stop recip .rocation of the shoe','rod TI is pushed rearward until stud 16 contacts head 68a, and is then maintained under rearward pressure until bore 68b is brought into alignment with stud 16, the latter then entering bore 681) and locking the forward end of lever 68. against movement. I6has fully jentered bore 68b, ball 82 engages into groove 88, locking rod 17 against accidental outward or forward movement. In the continued rotation of eccentric '14 the latter may touch roller 15 but exerts no effect upon lever 68, ,due'

to the position in which the latter is held. If desired, bore 681) may' be slightly inclined relative to stud 16, in proper direction and extent such that by forcing stud 16 into bore 68b. the forward end of lever 68 is movedoutward a slight distance beyond the outermost position to which itis moved by eccentric l4. This additional movement may be slight, just sufiicient to assure that the eccentric 14 will clear roller 15, and will.

not noticeably or objectionably affect the position of shoe 63 relative to roll 48, as shown inFigure'2. Head 68a is of sufiicient extent to preclude possibility of disposing stud '76 in such position as tolock the forward end of lever 68 in its inner position, in opposition to the outward movement imparted thereto by eccentric 14. 'Any other suit- When stud.

able means may be provided for stopping reciprocation of the shoe, within the broader aspects of my invention.

Preferably, when reciprocation of the shoe is stopped the latter is disposed with the ends thereof flush with the ends of the roll, as previously stated and shown in Figure 2. Stopping the shoe in that position. relative to the roll assures that the operating surface of the shoe extends the full length of the operating surface of the roll. That has the advantage of preventing marking or creasing of an article being ironed, such as might occur if an end of the shoe were disposed inward of the roll from the corresponding end thereof.

Subject to the above noted exceptions, the shoe is reciprocated lengthwise of the roll during the ironing operation. The reciprocating shoe acts upon the articles in two directions substantially perpendicular one to the other, lengthwise of the roll and transversely thereof. This operation closely approximates hand ironing, with the result that the articles have imparted thereto a smoothness of finish and sheen substantially equal to that obtainable by experienced hand ironing.

In the modification illustrated in Figures '7 and 8, shoe operating shaft 58,-when reciprocated, is positively moved in both directions. Bore 52a of boss -5la is equal in diameter to and forms a continuation of the bore. of boss 53. The outer end portion of shaft 58a is reduced, providing a neck 88 with shoulders 81 and 88 at the ends thereof. A lever 89, pivoted on stud 69, is provided at its rearward end with a vertically disposed form 90, which straddles neck 86 with the arms of this form contacting shoulders 81 and 88, the latter being of slightly rounded or frustospherical shape as shown. Lever 89 is provided, at its forward end, with a horizontally disposed form 9|, which straddles an eccentric 92 loose upon a coupling member 39a, similar to coupling member 39 except that it is provided with an outwardly extending circumferential flange 93 upon the upper face of which eccentric 92 seats.

' Flange 92 is provided with a series of arcuate notches 94 disposed to receive a locking pin 95 vertically slidable through cam 92.v Pin 95 is yieldingly urged downward by a leaf spring 96, secured at one end in a stepped groove 91 extending from the upper face of cam 92, the free end of this spring bearing upon a finger 98 fixed in pin 95, this finger operating in groove 91 and preventing turning of finger 95 while also limiting downward movement thereof.

Pin 95 is provided, at its upper end, with an integral trip arm 99 disposed at right angles thereto and projecting outward therefrom substantially radial to eccentric 92. Arm 99 cooperates with a tripping cam I00 secured upon the rearward end of a rod IDI non-rotatably and slidably mounted through boss 18 and plate 44a. Cam 100 is curved inward toward coupling member 39a, as in Figure 8, with its rearward end rounded and its upper face inclined upward and forward to a transverse horizontal surface l88a, as indicated in Figure 7, and is movable, by means of rod llll, from its inoperative position, shown in full lines in Fig. 8, into its operative position, indicated in the latter figure, and in Figure 7, by dot and dash lines. Rearward movement of rod l0! maybe limited in any suitable known. cam I is manner. In its operative position, disposed above and adjacent eccentric 92, with its inclined upper surface in the path of travel of trip arm 99, when the eccentric is rotated operated by power derived clockwise as indicated by the arrow in Figure 8. As arm 99 moves relative to cam Q09, it contacts the inclined cam surface and, in the continued turning of eccentric 92, is forced upward in opposition to spring 96 until it enters upon flat surface lUfla. This raises the lower end of pin above the upper face of flange 93, declutching the eccentric 92 from coupling member 39a, the latter continuing to rotate without affecting the eccentric. Pin 95 is so disposed that the eccentric 92 is declutched when the forward end of lever 89 is in its outermost position, shoe 83 being then in the position shown in Figure 2, in which position it is held by eccentric 92, the latter being then in dead center position with respect to cou- -pling member 39a and fork 9|.

When it is desired again to reciprocate the shoe 83, cam member I00 is moved into'inoperative position, releasing pin 95 which is moveddowmward by spring 96. In its downward movement pin 95 either enters directly one of the notches 94 in flange 93, or contacts the upper face of this flange. In the latter event, the continued rotation of coupling member 39a brings a notch 94 beneath pin 95 which immediately enters thereinto. After pin 95 enters a notch 94, slight turningof coupling member. 39a brings the following end wall of the notch into contact with the pin, causing eccentric 92 to rotate with member 39a. Any suitable means, other than that shown, may be provided for controlling reciprocation of the shoe, the particular means illustrated being exemplary only.

With the exceptions above described, the construction and operation of the modified form of machine illustrated in Figures 7 and 8 are the same as in the form illustrated in Figures 1 to 6, inclusive; and need not be described in greater detail. In both forms, the roll is driven by the motor 23, which conveniently also operates the means for moving the shoe to and from the roll and the means for reciprocating the shoe, and the latter is automatically positioned, when reciprocation thereof is stopped, with its ends flush with the ends of the roll. In the broader aspects of my invention, it is not essential that the shoe be from the motor 23. Any other suitable means may be provided for imparting the desired movements to the shoe, or the desired relative movements to the cooperating ironing members.

As above indicated, and as will be understood by those skilled in the art, changes in construction and arrangement of parts of my invention may be resorted to without departing from the field and scope thereof, and I intend to include all such variations, as fall within the scope of the appended claims, in this application in which the preferredforms only of my invention have been shown.
