12 Claims.

This invention relates to ironing machines, and has to do with ironing machines intended for domestic use and which employ a rotating roll and a cooperating shoe movable toward and away from the roll.

It is customary to dampen articles to be ironed preliminary to the ironing operation. It frequently happens that such articles are considerably damper at certain portions thereof than at others. If these articles be passed through the ironing machine at a uniform rate, there is the possibility that the damper portions of such articles will not be thoroughly dried during the ironing operation. It is an object of my invention to provide simple and eilicient means under control of the operator for momentarily stopping rotation of the article while the shoe is in contact with the article, so that the damper portions of the articles being ironed may be subjected to the heat of the shoe, at the discretion of the operator, for sufficient time to assure thorough drying thereof, such means being operable to cause again rotation of the roll while the shoe remains in opcrative relation to the same.

In the patent to Carl F. Anderson and Rudolph W. Janda, No. 1,656,656, dated January 17, 1928, for Ironing machine, there is disclosed an ironing machine of the character above referred to and which is provided with a box cover hinged to the bed structure of the machine and movable into position to enclose the ironing roll and shoe, this cov-cr, when opened, occupying a position alongside the hot shoe in parallel relation thereto and serving as a guard therefor. In the machine of the patent referred to, means is provided for quickly releasing the shoe and moving it away from the roll, in case of emergency. This means includes a release lever accessible from the front of the machine. A further object of my invention is to provide a release lever of proper length to extend well above the ironing shoe and roll so as to b3 readily grasped and operated by the operator of the machine and without danger of the operators arm coming in contact with the hit shce, this lever being capable of being disposed in a position below the shoe and roll so as not to interfere with positioning over the latter of a box cover the top wall of which, When in closed p( sition, is adjacent the top of the roll and the shoe. A further advantage of the relatively long release lever is that it facilitates operation of the release mechanism with ease and expedition. Further objects and advantages of my invention will appear' from the detailed description.

In general, the construction of the machine 25 of the instant application is similar to thatof the ironing machine disclosed in my Patent No. 1,867,839, dated July 19, 1932. The machine includes a bed plate I5 having a depending peripheral flange I6 to which are secured the upper ends 30 of supporting legs I1 in a suitable manner, as by nut and bolt means, these legs being formed of sheet metal of suitable gage and of angle cross section. The legs I'I are disposed at the corners of the bed plate, which is of rectangular shape in 35 plan, and may, if desired, be provided at their lower ends with suitable casters such as are disclosed in my patent above identified. Likewise,

any suitable means may be provided, if desired, for bracing the legs and maintaining them in 4o proper spaced relation.

Bed plate I5 is provided, adjacent one end thereof, with an opening which accommodates a main gear housing I8, the lower portion of this housing iitting through the opening and extending below the plate. Housing I8 is provided with an outwardly extending ange I9, at the ends and the inner side thereof, this ange seating upon the upper face of bed plate I5 and being secured thereto in a suitable manner, as by means of bolts 20 passing through the flange and the bed plate, nuts (not shown) being screwed onto these bolts. The outer side of the main gear housing is closed by a lower plate 2| suitably secured thereto, as by means of screws, and by an upper plate 22 suitably secured to 4the housing as by means of screws, one of which is shown at 23, this upper plate being provided, at its lower end, with an inwardly offset lip 24 which engages over the upper edge portion of plate 2l.

A worm gear housing 25 is suitably secured, as by means of screws 26 (Figure l), to the underface of housing I8. The housing 25 is provided with a depending boss (Figure 2) 2,1 which is suitably bored from its upper end for reception of a. shaft 28 rotatably mounted therein. This shaft extends upward through a bearing bushing 29 which fits through a collar 30 integral with and extending upward from bottom wall 3| of housing I8, this collar being concentric with the bore of boss 21. A worm gear 32 is keyed or otherwise suitably secured upon shaft 28 and is rotatably seated upon the upper end of boss 21. Hub 33 of worm gear 32 contacts a flange 34 at the lower end of bushing 29 and acts to hold this bushing against downward movement.

rIhe upper portion of shaft 28 is of reduced and squared cross section, at 35 (Figure 4) and fits into a correspondingly shaped bore in a clutch member 36 secured upon portion 35 of shaft 28 in a suitable maner, as by means of a set screw 31. The upper portion of the bore of clutch member 36 is of enlarged and circular cross section and receives the lower end of the lower reduced and squared portion 38 of a shaft 39 rotatably mounted at its upper portion through a bushing 4D which extends through a relatively thick rib 4I projecting from front wall 42 of the gear housing I8. A dog pointed screw 43 screws into the rib 4I, the point of this screw engaging into an annular groove 44 formed in the shaft 39 and holding the latter against endwise movement, this screw also passing through the bushing 40 and holding the latter in the rib 4I. Shaft 39 is disposed coaxially with shaft 28 and the lower end of bushing 46 contacts a cup washer 45 disposed about shaft 38. An expansion coil spring 46, mounted about shaft 39, is confined between washer 45 and an angle bearing ring 41 the lower fiange of which seats upon the upper face of a flange 48 at the lower end of a clutch member 49 slidably mounted upon squared portion 38 of shaft 39. Clutch member 49 tapers upward and is provided at its upper end with an annular shoulder 56, beneath which the other flange or arm of ring 41 engages, this ring fitting snugly about the body of the clutch member. The clutch members 36 and 49 are of known type and are provided, at their adjacent ends, with teeth which cooperate to establish driving connection between these members when they are in operative relation, in a known manner. The cup washer 45 and the ring 41 permit of the use of a spring of ample size for the purpose intended, and the ring 41 is advantageous as reducing friction and eliminating any tendency to binding of the clutch member 49 on the squared portion 38 of shaft 39.

Spring 46 acts to urge the clutch member 49 downward into operative engagement with the lower clutch member 36, thus establishing driving connection between the shafts 28 and 39. A bevel pinion 5Iy is suitably secured, as by means of a pin 52, on the upper end of shaft 39, above the rib 4I. This pinion meshes with a bevel gear 53 suitably secured, as by means of a pin 54, upon the outer end of a roll drive shaft 55. This shaft 55 is rotatably mounted through a boss 56 extending from the inner face of wall 42 of gear housing t8, and through a boss 51 aligned with boss 56 and extending from the outer face of wall 42. Shaft 55 extends through a tubular supporting arm 58 suitably secured, at its outer end, in boss 51. This arm 58 projects inward over bed plate I5 to within a short distance of 5 the other end thereof,- and may contain suitable antifriction bearings for rotatably supporting shaft 55 in arm 58.

A worm shaft 59 is rotatably mounted in the worm gear housing 25, in a suitable manner, and 10 carries a worm 68 rigid therewith, this worm meshing with the worm wheel 32. Shaft 59 extends beyond the inner side of housing 25, beneath bed plate I5, and is connected by a suitable coupling 6I to armature shaft 62 of an electric motor 15 63 supported by brackets 64 suitablysecured to the bed plate. Suitable means is provided for connecting the motor into an electric circuit.

Upon closing of the motor circuit, worm wheel 32 drives the shaft 28, the direction of drive of 20 the motor being such that this shaft is driven in a clockwise direction when viewed from above. With the clutch member 49 in its raised or inoperative position, shaft 28 and clutch member 36 rotate without effecting rotation of shaft 39. 25 Lowering of the clutch member 36 serves to clutch shaft 39 to shaft 28, these two shafts then becoming, in effect, a single shaft which serves to drive the roll shaft 55 through the pinion 5I and bevel gear 53.- Shaft 39 is thus driven, at this 30 time, in a clockwise direction as considered in Figure '7.

Sleeve 58, in conjunction with shaft 55, provides means for rotatably supporting a roll 65 comprising a sheet metal body 66 of cylindrical 35 shape, and suitably arranged reenforcing rings disposed within this body and secured thereto in a suitable manner, as by box welding. One of these rings, designated 61, is disposed adjacent the open end of body 66 and extends inward to 40 within a short distance of the end of sleeve 58. 'I'he cylindrical body of the roll is adapted for reception of a. suitable length of fabric which may be secured thereon in a suitable manner and is wrapped about the same to form a pad 68 com- 45 posed of a plurality of layers of the fabric, there being a suitable fabric cover 69 disposed over the pad thus provided.

The end portion of shaft 65 remote from housing I8 is flattened at 16 and fits through a corre- 50 sponding slot 1I in reenforcing ring 61. The flattened 'portion 10 of shaft 55 is threaded, and ring 61 is clamped between a nut 12 at the inner face of the ring and a cap nut 13 at the outer face of the ring. The nut 12 abuts the outer 55 face of a ball bearing structure 14 of known type, suitably mounted in the outer end of Ysleeve 58, and coacts with bevel gear 53 and boss 66 to hold shaft 55 against endwise movement, the two nuts 12 and 13 screwing onto the end portion 10 of 60 shaft 55. The roll is thus mounted for rotation on the axis of arm 58 and when it is desired to remove the roll, this may readily be accomplished by removing cap nut 13, after which the roll may slide lengthwise off of the shaft 55 and arm 58, 55 away from the gear housing I8. To replace the roll, this operation is reversed.

An eccentric structure 15 is mounted for free turning movement about the bearing bushing 29. This structure is provided, at its underside, with 70 a reduced eccentric element 16 which seats upon the upper face of collar 30. An eccentric strap 11 fits above eccentric element 16. This strap is formed at one end of an arm 18 which is provided, at its other end, with a fork 19. 'I'his fork 75 receives a block 88 pivotally secured in the fork, on a vertical axis, by a. pin 8|. This block is also pivotally secured, by apin 82, to the lower end of an arm 83 secured upon and depending from a. shoe operating shaft 84 which is rockably mounted through a bearing sleeve 85 projecting from the inner wall of gear housing |8. This sleevey 4lng concentric with shaft 84. This provides a lost motion connection between arm 81 and shaft 84 which permits of limited rocking movement of the arm independently of the shaft.

A fork member 9| is pivotally connected at its lower end, by a headed pin 82, to the other end of arm 81. This fork member is provided with arms 83 which extend beneath the lower flange of angle ring 41. Adjacent its upper end, fork member 8| is provided with a vertical slot 84 which receives enlarged element 43a of screw 43, there being a washer 85 confined between the head of this screw and the outer faceof member 8|. In this manner, the 'fork member is slidably mounted on rib 4| of housing |8 for vertical movement. The fork member 9| is further provided, adjacent its upper end, with two lingers 96 disposed at each side thereof and extending therefrom oppositely to the arms 93. A clutch shaft 91 is rockably mounted in housing 8 transversely thereof and adjacent fork member 9|. This shaft is flattened at 81a (Figure 3) and fits snugly through correspondingly shaped openings 98 (Figure 8) in the arms of a U-shaped cam member 98. Member 99 embraces fork member 9| and the arms of member 99 are rounded to provide cam surfaces |88. The arms of member 99 are also provided with fingers |8| adjacent the upper ends of the cam surfaces |88 and disposed to contact the outer surface of member 8| when the latter member is in lowered position, as in Figlure 8. In this position of member 9|, fingers 96 rest upon the upper edges of the arms of member 99, which is horizontal position, and elements |8| contact member 9| adjacent the fingers 96. A suitable handle |82 is secured upon shaft 91, exterior of housing I8 and at the front wall thereof. With shaft 91 in the position illustrated in Figures 2 and 3, fork member 9| is in its lowered position and clutch member 48 is lowered into engagement with clutch member 38 thus driving the roll 65 in the manner previously described. By turning the shaft 91 in an arc of 90 and in a clockwise direction, as viewed in Figure 3, cam surfaces |88 of cam member 98 are caused to exert a camming action on fingers 86 so as to raise the fork structure 9| sufficiently to move clutch member 48 upward into its inoperative position, in which it is out of engagement with clutch member 36, thus stopping the roll 65. In this position of the cam member 89, the pressure exerted by spring 46 is transmitted to the cam l member through fingers 96, the line of pressure being substantially in the plane of the axis of shaft 91. This, in conjunction with the friction between the parts, serves to hold the clutch member4 49 in its raised position. Turning the shaft 91 in the opposite direction serves to return the clutch member 49 to operative position so as to drive again the roll 65. In this manner,

the roll may be stopped and started at the will ofthe operator, by suitable turning of handle |82.

Eccentric member 15 ls provided with an upwardly projecting flange |85 concentric with 5 shaft 28, the upper face cf this member being flat or plane from the flange to the outer 'edge of the body portion thereof. Member 15 is provided,- in the upper face thereof and adjacent flange |85, with a channel |86 of appreciable l0 depth (Figure 5), which receives a ltension coil spring |81. One end of this spring is secured, by a pin |88, to member 15. At its other end, spring |86 is provided with an eye |89 which receives a tongue ||8 pressed downward from a l5 clutch operating ring which fits about flange |85 and seats upon the upper face of eccentric member 15, this ring forming a closure for the upper end of channel |86. An annular clutch yoke ||2 is disposed about flange |85 and seats 20 upon ring This yoke is provided with diametrically disposed notches ||3 which receive angularly disposed tabs ||4 formed integrally with the ring and projecting upward therefrom, these tabs being outwardly offset relative to the 25 body portion of the ring. A star wheel ||5 is disposed within the pocket or recess defined by flange |85 and ts about the squared portion 35 of shaft 28. This star wheel and the yoke ||2 are preferably of laminated construction, the 30 elements thereof being suitably secured together, as by riveting. However, the yoke and the star wheel may be otherwise constructed if desired. An annular cover plate |6 is disposed beneath clutch member 36 and seats upon flange |85. to 35 which it is secured by screws |85a, this plate projecting outward beyond this flange and acting to hold the yoke ||2 and the star wheel ||5 and cooperating parts against upward movement.

Referring more particularly to Figure 4, flange 40 |85 is provided with a slot ||1 extending therethrough and of a size to accommodate a clutch disc I8 of a size and shape to t into the notches H50. of the star wheel ||5. Clutch yoke ||2 is provided, in its inner edge, with a recess ||2a of 45 proper depth to receive the portion of disc ||8 Which projects beyond flange |85 when this disc is in its outer or inoperative position. This recess is provided with an extension ||2b of reduced depth to accommodate the outer portion 50 of the disc ||8 when the latter is in its inner or operative positon. The spring |81 urges ring in a clockwise direction, as considered in Figure 4.

A trip finger ||9 is roekably` mounted upon a boss |28 projecting inward from the front wall 5" of gear housing I8. A control rod |2| is slidably mounted in the top of housing I8 and is pivotally connected at its lower end to finger ||8. A button |22 is suitably secured upon the upper end of this rod, and an expansion coil spring |23 is GO mounted about the rod |2| and confined between this button and the bottom of a bore |24 provided in housing |8 to accommodate the button. Spring |23 serves normally to hold the rod I2| raised, thus normally holding the outer end of 6* trip nger I9 depressed and in contact with the upper surface of cam member l5. The nger, when in its normal operative position, is disposed to contact tabs ||4 of the ring This serves to hold the yoke ||2 in such position that recess 70 |2a thereof is in allgnment with slot ||1, due to contact of tabs ||4 with the end walls of notches ||3. At this time the disc ||8 is in its outer or inoperative position, and the star wheel H5 is free to turn with Shaft 2s independently 7' of the eccentric member and other parts associated therewith. At this time, the spring |01 is under tension and tends to move the ring in a clockwise direction, as viewed from above. In Figure 4, the shoe operating shaft 84 has been rocked in a counter-clockwise direction, as considered in Figure 2, into its extreme position, the

eccentric member being at this time disposed in its extreme position to the right of shaft 28 and being on dead center with this shaft and pin 8|. This provides an eccentric lock which serves effectively to hold the shaft 84 in rocked adjustment.

When it is desired to rock the shaft in the other direction, finger I |9 is raised into inoperative position. Spring |01 then turns the ring so as to bring the tabs ||4 into contact with the other ends of the notches ||3, the spring then acting to turn both the ring and the clutch yoke I2 in a clockwise direction as viewed in Figure 4. This movement of yoke ||2 moves the disc 8 inward into engagement with star wheel I5 and, the shaft 28 being driven, clutches the eccentric member to the star wheel for rotation therewith. This movement of the yoke ||2 serves first to move the disc ||8 inward, after which the reduced portion ||2b of recess ||2a is brought into position to fit about the outer portion of disc I8 thus holding it in its inner or operative position.l 'I'he eccentric member turns with the star wheel through a half rotation, at which time the other tab ||4 of ring ||2 contacts trip finger ||9, it being understood that this trip nger is returned to its operative position by spring |23 immediately upon release of rod |2|. Upon contact of the tab ||4 with the trip finger, ring is held against turning movement, yoke 2 continuing to turn with the star wheel vuntil the end walls of notches !|3 contact the tabs, at which time the yoke also is held against turning movement. Upon continued turning of the star wheel and the eccentric member, slot ||1 is again brought into alignment with recess |2a, atwhich time disc |18 is forced outward into this recess, by the pressure exerted upon this disc by the star wheel. This returns the parts to their relative positions of Figure 4, except that the disc 8 andv asso-l ciated parts will have been moved through an arc of 180 from the positions of this figure, and the eccentric element will have been turned through an arc of 180, at which time the shoe operating shaft |84v has been rocked into its extreme position in a clockwise direction as considered in Figure 2. At this time, the eccentric element is again on dead center with the shaft 28 and pin 8 l, providing an effective locking means for holding shaft 84 in its rocked position.

An arm |25 (Figure 1) is suitably secured, as by means of a pin |26, upon shaft 84 adjacent the holding member 86. This arm extends upward from the shaft and is bifurcated atits upper end for reception of a reduced neck (Figure 10) |21 extending rearward from a head |28 which is secured upon the forward end of an adjusting rod |29. Neck |21 abuts a head |30 at the forward end of a thimble |3|, which is also mounted upo'n the rod |29. 'I'his thimble screws through a cruciform member |32 rockably mounted in a shoe carrying arm |33. This arm is bifurcated at its lower end, which straddles arm |25, and is loosely mounted upon shaft 84. At its upper end arm |33 is suitably pivoted to a shoe |34 which cooperates with the ironing roll. This shoe has a concaved forward face to fit above the roll, when the shoe is in its forward position, and is provided with suitable heating means, preferably electrical means which may be controlled by the same switch which controls the motor. 5

Rod |29 has a pin and slot connection to thimble |3| for rotating the latter while being slidable therethrough. A knob |35 is suitably secured upon rod |29 at the outer end thereof for rotating the rod in desired direction. The forward 10 face of this'knob is recessed and receives one end of an expansion coil spring |36, the other end of which seats in a cup washer |31 mounted about the rod and abutting the rearward end of thimble 3|. The means for coupling the arms 15 |25 and |33 together is the -same as that disclosed in my above identified Patent No. 1,867,839, and need not be described here in greater detail.

With the arms |25 and |33 coupled together, 2o when shaft 84 is rocked in a counter-clockwise direction, as viewed in Figure 2, arm |25 acts. through head |28 and rod |29 and associated parts to swing the shoe supporting arm |33 forward thus bringing the shoe into contact with 25 the roll or the work thereon. After this occurs arm |25 moves forward a short distance, placing spring |36 under compression so that the shoe is held to the roll by spring pressure. By rotating rod |29 the effective spring pressure 30 exerted on the shoe can be regulated as required.

A release lever 40 is connected to member |32 for rocking the same to couple and uncouple the arms |25 and 33. This lever is provided, at its lower end, with a finger 4| which passes through 35 the upper arm of member |32, this finger being disposed at right angle to the lever. n

' Arm |32a of member |32 and through which finger |4| passes, is provided with two notches |42 and |43 extending from the opening which 4o receives finger |4|, these notches being at the rear face of arm |32a. An expansion coil spring |44 is mounted about finger |4| and confined betwe'en the forward face of arm |32a and an abutment in the form of a washer |45 suitably secured 45 upon lfinger |4| at the forward end thereof. This spring urges lever I 4| toward arm |32a so as to hold it in one or the other of the notches |42 and |43. When lever |40 is in notch |42 it is disposed in vertical position and projects well above the shoe |34 and the roll 65. A knob |46 is provided at the upper end of lever |40 for convenience in grasping the same and, in the vertical position of the lever, this knob is disposed a suiiicient distance above the hot shoe so as to be readily grasped by the operator from in front of the machine without danger of the operators arm or hand coming into contact with the hot shoe. The considerable length of lever |40 is also of advantage in facilitating operation 60 of the coupling means. When the lever |40 is disposed in the notch |43 it is at an angle of approximately 45 to the horizontal so that knob |46`is below the top of shoe |34, and this shoe and the roll may be enclosed by a box cover |41 65 seating upon the bed plate I5 with the top wall of this cover adjacent the top of the shoe and the roll. I

When the machine is being used for ironing, the lever |20 occupies the vertical position shown 70 in dotted lines in Figure 1. By swinging this lever rearward, member |32 is rocked so as to disengage head |28 and neck |21 from arm |25 and swing head 28 upward and rearward into contact with arm |33, thus swinging this latter acarrea element 86a formed integrally with the holding' member 86 and projecting into the path of movement of arm |33. In order to couple the two arms together, lever |40 is swung forward. In the forward movement of this lever head |28 contacts the forward face of the upper end of arm |25and neck |21 passes into the slotted end thereof, coupling the arms together.

In the normal operation of the machine," cam member 99 is turned to its inoperative position illustrated in Figure 3 thus permitting of vertical movement of fork member 9| in either direction. When the shoe is in its open or inoperative position, pin 89 contacts the wall at the upper end of slot 90 so-as to hold arm 81 in raised position, thus holding clutch member 49 in its raised or inoperative position against the tension of ,apringI ' I'he shafts 28 and 39 are then declgitched so that the roll is not rotated when the "shoe is out of operative relation thereto. Upon movement of the shoe into operative relation to the roll, shaft 84 is rocked in a counterclockwise direction, as considered in Figure 2, and spring 46 acts to move clutch member 49 downward into engagement with clutch member 36, at which time arm 81 occupies the position illustrated in Figure 2. Accordingly, when the shoe is moved into' operative relation tol the roll, the shafts 28 and 39 are coupled together to drive the roll 65, in the normal operation of the machine. With the shoe in operative relation to the roll, clutch member 49 may be raised into inoperative position,y by turning the clutch control handle |02 in proper direction, at the pleasure of the operator. This permits of momentary stopping of the roll so as to assure thorough drying of relatively damp portion of the article being ironed, in the manner previously described. Also, by retaining the clutch member 49 in its raised or inoperative position, the shoe may be moved toward and away from the roll while the latter remains stationary, by proper operation of the rod I2 for pressing suits and like articles. It will thus be observed that under normal conditions the roll 65 is driven when the shoe is in operative relation to the roll, but rotation of the roll may be prevented at the will of the operator and as conditions require.

The box .cover |41. may be constructed and mounted as in my Patent No. 1,867,839, or as in the Anderson and Janda patent, above-identi ed, and the clutch mechanism for controlling operation of the shoe and the means for coupling the shoe supporting arm to the arm which is secured upon the shoe operating shaft are similar to the corresponding means disclosed in my above identified patent and need not be further illustrated nor described here, it suflicing to note that suitable means is provided for operating the shoe shaft 84 and suitable means is provided for establishing operating connection between -this shaft and the shoe.
