1 Claim. (Cl. 38-59) This invention relates to ironing machines of the type having a padded roller mounted on a stand and positioned to coact with a heated shoe or buck, and in particular an ironing machine having three primary movements with the roller adapted to oscillate about its axis, rotate, and slide longitudinally whereby a plurality of ironing actions are obtained which make it possible to iron materials with substantially the same movements produced in hand ironmg. g

The purpose of this invention is to provide a universal ironing machine in which reciprocating movements are combined with rotary travel of a roll and in which substantially all types of materials and garments may b ironed thereby.

Ironing elements of ironing machines have been provided of various types and designs to compensate for dif-, ferent materials and articles to be ironed thereon and to imitate ironing by hand, however, it has been found difficult to combine the rotary and sliding movements where the sliding movements are both transversely and longitudinally disposed.

With this thought in mind this invention contemplates an ironing machine having a roller mounted on an den-- gated spindle with the roller positioned to coact with a heated buck or shoe and in which operating means are provided for elevating and lowering the buck, for oscillating the roller with transversely disposed movements,

for rotating the roller continuously, and also for sliding the roller IOngitudinally on the spindle and in relation to the buck.

'The object of this invention is, therefore, to provide means for forming a combination or universal ironing machine in which a roller journalled on a spindle is rotated, and reciprocated transversely and longitudinally and in which a buck, mounted to coact with the roller, is adapted to be raised and lowered to compensate for'dif-E ferentmaterials or articles being ironed. I Another object of the invention is to provide means in an ironing machine whereby an ironing roller is adapted to be reciprocated transversely, reciprocated longitudinally or rotated continuously in which the different move ments are controlled by cams and in which the cams are, selectively, actuated by clutches.

A further object of the invention is to provide'a univer-' sal ironing machine in which the ironing roller is reciprocated transversely, rotated continuously, or reciprocated' longitudinally and in which the heated shoe or buck is.

one end thereof, a padded roller mounted to slide longi-.

tudinally and rotate on said spindle, a heated buck positioned above the roller, foot actuated means for elevating and lowering the buck, and a plurality of cam actuated.

clutches for engaging and disengaging operating devices for,selective1y,-actuating the different parts of the ironer.

spindle and forming the core of the roller, :1 shoe 13 hav- 3 ing an arcu ate'under' surface 14 and having electric heating elements 15 and 16 therein, a post 17 on theupper end of which the shoe is mounted with an arm 18, and a plurality of cams and clutches mounted in the upper portion of a housing mounted on wheels or rollers 19 and having a base 20.

The roller 10 is formed with a fabric cover; to which the numeral 10 refers, positioned on a cylinder or casing 21 and, as illustrated in Fig. 4, the cylinder is .provided with spiders having bands 22 supported from hubs 23 with spokes 24, the spiders being positioned in the ends,- and thespider, at the inner end being rotated against a collar 25 on the sleeve 12.

The cylinder 21 is secured to the bands 22 of the spiders with set screws 2andthe. collars 25 are securedin position on the sleeve 12 with set screws 5.

The ironing machine has four cams, three of these cams being used to shift the position of the rotors. The cam at 38 is designated as the horizontal oscillation rotor gc'am. The cam 38 is provided with a groove 37 which is engaged by a projection 36,011 the arm 26 that is clampedto the sleeve 12 that is slidably mounted on thespindle'. 11 for the roller 10. The cam at 104 is designated as the vertical oscillation positioning cam. The cam 104 is provided with a groove 107 which is engaged by the :projection -108 of a slider 109. The cam at 96 is designated as the vertical clockwise positioning cam. The cam 96 .is provided with a groove 95 which is engaged by a projection 94 of a slider 93. The cam 71 is designated as the horizontal oscillation positi'oning cam. The cam 71 is providedwith a groove 70 that is engaged by a projection 69 on a plate 67 that is attached to the slider 65. The projections on the sliders engage their respective grooves in their respective cams as set forth to effect the operation of the various rollers,as will be later described.

I As illustrated in Figs. 8 and 9 an arm or lever 26 is clamped on the sleeve 12 between the collar 25 and a similar collar 27 with the portion of the sleeve positioned between the collars clamped in an arcuate section 28 of the arm 26 with a complementary arcuate section 29 having a base 30 and positioned in a recess 31 of the arm and having-a flange 32 extended from the opposite end. The flange 32 is secured by bolts 33 to a flange 34 on theupper endof the arrn 26 and the base 30 is secured to the arm 26 with bolts 35. The lower end of the arm 26 is provided a projection 36 that extends into a groove 37 in a cam 38 on a shaft 39 journaled in vertically disposed members 40 and 41 of an inner frame, with bearings '42 and 43. I

The supporting frame, of which the members 40 and 4 1 form parts is provided with additional verticallydisposed members '44 and 45 which are mounted .on a base 46 and, as shown in .Fig. 4 the upper ends of the members are connected with a horizontal member 47. Thefr-a-me is also provided with an upper intermediate member 48, alower member 49 extended between the members 41 and 44 and a connecting member 50 by which the member 40 is mounted on the member 41.

Upon rotation of "the cam 38 from the position shown in Fig. 4, the projection36 on the lower end of the arm 26 follows the groove 37 whereby the arm 26 moves'outwardly carrying the ironing roller 10 and sleeve 12 longitudinally of the spindle 11 whereby upon continued rotation of the cam 38 the roll 10 reciprocates longitudinally.

The cam 38 is mounted on a sleeve -51, to which the sleeve is secured with a set screw 52 and, as shown-in Fig. 4, the extended end of the sleeve 51 is provided with a jaw 53 of a clutch having a coacting jaw 54. The jaw 54 is carried on one end of a sleeve 55 on the opposite end of which a clutch collar 56 is mounted, the clutch collar being held against the flange 57 with a spring 58.

The arm 26 is also provided with a guide bar 59 that extends through a U-shaped bracket 60 that is secured to the frame member 40 with bolts 61. The 'end wall 62 of 4 the housing is provided with an opening 63 through which the.bar.59 may extend.

The clutch collar 56 is actuated by a yoke 64 extended upwardly from a slider 65 mounted on the member 49, as illustrated in Figs. 15 and 16, the slider 65 extending over the upper surface of the member 49 and having a flange 66 extended over the member; and the slider being secured on the member with a bottom plate 67 that is attached to the slider with screws 68. The plate 67 is provided with a projection 69 "that extends into a cam groove 70 of a cam 71 and the cam 71 is mounted on a shaft 72 which is journaled in the frame members 41 and 44 with bearings 73 and 74, respectively.

The shaft 39 is rotated by a motor 75 through an endless belt 76 that is trained over a pulley 77 on the motor shaft and a pulley 78 on the shaft 39, and the shaft 11 is rotated from the shaft 39 with a chain 79 that is trained over a sprocket 80 on the shaft 39 and the sprocket 81 on the shaft 11. The sprocket 81 is secured to a sleeve 82 with a set screw 83 and, as shown in Fig. 4, the sleeve 82 is-provided with a clutch jaw 84 that coacts with a similarjaw 85 on a sleeve 86 on the opposite end of which is afiange 88 against which a clutch collar 89 is held with a spring 90. The sleeve 86 is keyed to the shaft With'a key 91 and the clutch collar 89 is actuated by a yoke 92 extended from a slider 93 slidably mounted on a member 48 and having a projection 94 extended from the lower side which extends into a groove 95 of a cam 96 on a shaft 97.

The shaft 97 is rotated from the shaft 72 with an endless chain 98 that is trained over a sprocket 99 on the shaft 97 and over a sprocket 100 on the shaft 72.

The extended end of the shaft 72 is provided with an index wheel or pointer 101 by which the shaft, with the cam 71 thereon, may be rotated until the projection 69 is in the high point 102 of the cam slot at which time the slider 65 is moved on the member 49 until the jaw 53 of the clutch is in engagement with the jaw 52 so that with the jaw 53 secured to the shaft 39 with a key 103 the cam 38 will be rotated, moving the projection 36 longitudinally with a reciprocating action whereby the arm 26 longitudinally reciprocates the ironing roller 10.

At the same time the chain 98 rotates the shaft 97, turning the cam 96, and also turning a cam 104 positioned-on the opposite end of the shaft.

With the cams 71, 96, and 104 adapted to be rotated by the lever or index wheel 101 these cams are adapted tobe set .so that the high point of each cam groovemay be positioned to close its respective clutch, whereby the different movements of the machine are independently controlled.

By this means a high point 105 of the cam groove 95 of the cam 96 is adapted to be set to close the clutch jaws 84 and 85 whereby the shaft 11 will rotate .in a

clockwise direction continuously so that ironing may be continued in the conventional manner.

At the same time the movement of the member 101 may be continued to the position illustrated in Fig. 4 in which position the high point 106 of the cam groove 107 of the cam 104 holds the projection 108 of a slider 109 on the member 48 whereby a clutch jaw 110 is in engagement with a clutch jaw 111 on the inner end of a sleeve 112 on the end of the shaft 11. With the jaws 110 and 111 'in engagement and with a sleeve 113 on which the jaw 110 is positioned keyed to the shaft '11 with a key 114 the shaft 11 with the roller 10 will be reciprocated transversely.

The sleeve 113 is provided with a clutch collar 115 that 'is urged awain'st a flange 116 by a spring117, and the collar 115 is actuated by a yoke 1'18 extended from the "slider ,109. 7

'As illustrated in Figs. 4a'nd '5 the sleeve 1'1'2 isprovide'd with a lever 119 that is secured to the sleeve with aset screwv 120 in a hub'121 and the lower end of the lever is connected to a link 1% with a p'inf1'23. ,The

mam

opposite end of the link 122 is pivotally connected by a pin 124 to the end of an arm 125 that is secured to the shaft 39 with a set screw 126 in a hub 127 of the arm. With the parts mounted as illustrated in Fig. rotation of the shaft 39 carries the arm 125 around a circle with the link 122 moving the lower end of the lever 119 from the position shown in full lines to the position shown in dotted lines whereby the shaft 11 is turned to an angle of substantially degrees. With the parts moving continuously from the position shown in full lines to the position shown in dotted lines and from the position shown in dotted lines back to the position shownin full lines the shaft 11 oscillates or reciprocates transversely. With the sprocket 81 mounted on the sleeve 82 the sprocket and sleeve are free to rotate with the shaft 39 as the motor is in operation and a rotary motion is transmitted to the shaft 11 when the jaws 84 and 85 are in engagement. By the same means the shaft 11 is recipro cated transversely or oscillated when the jaws and 111 of the clutch actuated by the cam 104 are in engagement, as shown in Fig. 4.

The inner frame in which the cam and clutch shafts are mounted is positioned in an upper compartment or section of a housing forming the stand of the ironer with the base 46 of the frame positioned on a base and with the upper portion of the frame supported laterally by threaded studs 131 and 132, the upper ends of which are threaded into an upper plate 133 and the lower ends of which are threaded into the upper member 47 of the frame. The end plate 62 is provided in one end of the upper section of the housing and the plate 134 is provided at the opposite end. The housing is also provided with a rear plate 135 and a front plate 136 in which a door 137 is provided, as shown in Fig. 1. The door 137 is secured to the plate 136 with hinges 138 and 139 and a latch 140. The plate 138 is secured to the side and end plates of the housing with screws 141. The plate 62 is provided with an offset section having a horizontally disposed portion 142 and a vertical section 143 and, as shown in Fig. 4, the portion 142 is provided with a slot 144 in which the arm 26 travels.

The plate 62 is also provided with a projection or indicator 145 that is positioned to coact with the lever or index wheel 101 to show which cam is in the operative position or in positions wherein the clutches are engaged or disengaged.

The ironer housing or stand is also provided with a lower back plate 146, end webs 147 and 148 and an intermediate web 149. These parts are mounted on the base 20 and extend upwardly therefrom and, as shown in Figs. 1, 10, 11, and 12 the buck or shoe 13, which is carried by the arm 18 extended from the post 17 is mounted on the rear plate 146. The post 17 is slidably mounted or telescopes in a tubular section 150 and the post is secured in adjusted positions with a set screw 151 in a collar 152 on a mounting plate 153.

The lower end of the post 17 is provided with a foot plate 154 that extends forwardly, as shown in Figs. 10 and 11, so that it is within reach of a foot of the operator whereby the shoe may be held downwardly upon the ironing roll 10 as the machine is in operation.

A foot crank 155 is provided for elevating the shoe and, as illustrated in Figs. 1 and 12 the crank 155 is pivotally mounted by a pin 156 in spaced vertically disposed bars 157 and 158 and, as illustrated in Fig. 12, the post is elevated by placing a foot on a pedal 159 and pressing the upper end of the lever downwardly, as shown in dotted lines whereby a roller 160 in the opposite end of the lever presses upwardly against the under surface of the foot plate 154. With the post and shoe in the elevated position a latch 161, pivotally mounted in supports 162 by a pin 163 is urged inwardly by a spring 164 whereby one side of the plate 154 snaps into a notch 165. By this means the post and shoe are retained in an upwardly extended position and when it is desired to lower the shoe the latch 161 is actuated by placing a feet on a. projection 166 extended from the outer edge thereof.

The post 17 is resiliently supported from the lower end of the tube 150 with springs 167 and 168 on rods 169 and 170, respectively, the rods extending through a bar 171 on the lower end of the tube 150 and also through the ends of a bar 172 on the post 17. The upper ends of the rods are provided with heads 173 and 174 and the lower ends with nuts 175 and 176, respectively whereby tension on the springs may be adjusted. j

The front or cover plate 136 is provided with an ex tension 177 that extends to the web 147 and the extension is provided with a knob 178 for adjusting the temperature of the shoe of the ironer and also a knob 179 for actuating a switch to turn the circuit of the rotor on and off.

It will be understood that a conventional shoe or buck may be used in combination with the roll 10; however, as illustrated in Figs. 13 and 14, the shoe 13 is provided with a cover plate 180 having an insulating liner 181 and the cover is secured to the shoe with screws 182. The shoe is provided with end sections 183 and 184 in which the heating elements are mounted with tubes 185 of insulating material. The heating elements, which in the. design shown, are in the form of coils are wrapped around tubular insulating ,rods 186 and 187 and the coils are connected to a brass rod 188 at the center. The rod 188 is also supported in the end members 183 and 184 with tubular insulating members 189. By this means the temperature of the shoe may be regulated as desired.

The shoe 13 is suspended from the arm 18 on the upper end of the post 17 with studs 190, the lower ends of which are connected to a base plate 191 that is connected to the cover plate 180 with screws 192 and, as shown in Fig. 13, the'studs extend through hubs 193 on the end of the arm 18 and the threaded upper ends of the studs are provided with adjusting nuts 194. Springs 195 are positioned between the lower surface of the arm 18 and shoe.

Figure 22 illustrates a typical connection of a wire of an electric circuit to the electric heating element through the cover plate 180, the cover plate being provided with a threaded plug 196, of insulating material and the plug having a stud 197 secured therein. The lower end of the stud 197 provides a terminal 198 for a wire 199, and a connector 200 on the wire by a screw secured against a nut 201 on the end of the stud. The stud is also provided with a projection 202 to prevent the stud rotating as connections are made thereto and the upper end of the stud is provided with a threaded section 203 on which a nut 204, of insulating material, is threaded. A wire 205 extends through an opening 206 in the upper end of the nut and the end of the wire is secured to the end of the stud 197 by soldering or other suitable means.

As shown in the wiring diagram shown in Fig. 2 the knob 179 actuates a switch 207 one terminal of which is connected by a wire 208 to a source of current supply with the wire being connected to terminals of the motor 75 and the other terminal of the switch 207 being connected by a wire 209 to the other side of the source of current supply. The wire 209 is also connected by a wire 210 to one of the terminals, such as the terminal shown in Fig. 22, of the electric heating element and the other terminal of the electric heating element is connected by a wire 211 to a resistance coil 212 of a rheostat or regulator 213. The opposite terminal of the control device 213 is connected by a wire 214 to the wire 208. It will be understood, however, that current may be supplied to the ironer by other suitable means.

As illustrated in Figs. 20 and 21 the shaft 72 may be rotated with a wheel or lever, as indicated by the numeral 101, and the wheel may be provided with points 215, 216, and 217 to correspond with high points of the area-37s cams,,.the high points being, indicated in the diagram shown in Fig. 20'.

With the machine designed and assembled in this manner three separate and distinct movements are accomplished such as an oscillating movement with the roller rotating first in one direction and then in the other across or below theishoe or buck; a continuous rotary motion with the cylinder rotating continuously in the same direction; and third, a longitudinal reciprocating motion with the roller sliding longitudinally on the shaft and under the shoe.

By this means substantially all types of garments and other articles may be rapidly ironed on the machine, andin ironingd'ifiicult articles the operator may readily shiftfrom one motion to another.

All bearings are provided with grease cups or fittings and 'as shown in Figure 2, threaded openings 3 are provided in .the frame for grease cups.
