' Be it known that I, JOHN MIKUPNSEK, a

citizen of'- the United States', reslding at State of Iowa, have invented vnew and useful I ma Ironing Machines, of which trol being efected by a foot pedal.

wheels 13 so that the machine may be easilyv moved about The stand has upright anglebarsll at Aits corners'to the upper l ends of" 60.

which is 'fastened a frame 15, above which latter the elements 10 and 11 are positioned. Over the angle4 bars 14, from three sides of the machine-are. fastened sheet metal cover nrgs 1 6, and in front is aA double door 17 swinging on hinges 18. When the machine isnot in use, a hood 19 maybe placed on the frame 15 to exclude dust ffrom ,the parts above the latter and toconcealthe same.'

The machine is a portable one,.and it. is de.- i

signed so that it may Jbe installed in any conyenient room in a dwelling, Awithout detractingfrom the appearance thereof.` 'Thefma- .chine 1s also so designed thatI it .takes up no more space thanan ordinary domestic sewing machine, and when constructed ina cabi-- net type 1t is a fitting piece'of furniture.

To the base frame 12 is vfasteneda hou'sl ing frame v2 0 over' which is set ahousing' c o'veil 21 enclosing most of themechanisml i The frame 12 and` housing 22, have'iverti-v :cally alined bosses carrying pivot screws 27 supporting aV l framei 28 'carrying an electric or other motor 29 having its shaft'fitted'- with a- 'friction wheel I3 1 for driving'a, concave friction d1sk'32-carr1ed by a shaft- 33. The

frictionwheel'v vengages'the concave side iss Qf the, disk saaie sid-@being Spherical, the y center of the fcurvature lying upon. the axis of .thefpivot screws 27. i.fIhe friction wheel i i engages the friction disk edgewise, and its with -the :curvature of -the concave friction surface of the disk. In" orderto take 'up thel :end j thrust, 'ja f ball bearing 3 4 is .interposed 'between-.the .frictonlvheel and. the 'bearing on ythenfiotor yframefor thefniotorshaft.-

'f'lhemotor 29is-fastened at its base to an arm 355p1vQted, as shown at 36 to the frame 28, Against fthe arm 35 bearsp'ne-end of a v top,` the motor. 291is supported by jpl-mud t bu-toffset-latera1lyi'with respect to the pivots 27.'. u

95 edge' having a convex curvature coinciding f face of '.the frame 28, it Iwill beseen that the fric- -ver 26 carries 'a latch seen that the spring 3'? tends to turn the' motor 29 in a counter-clockwise direction, whereby the friction wheel 31 vis .held pressed against the friction .disk 32, insuring thereby a steady andeven driving contact even if the center of the spherical surfaceof the disk does not coincide exactly with the pivots 27, or if said surface should wear in on place more than in another. Y

The foot lever 26 is connected to the frame 28 for swinging the latter about its pivots 27. This motion of the frame 28 shifts the friction wheel 31 to and from the center of the disk 32, whereby the speed at .which the latter is driven is varied. In order to lockthe fra-me 28, the foot lepin 40 engageable with a notched sector 41 on the frame 12.

The housing enclosing' the motor and the friction gear, 1s made in two sections-22 and 23, the former being stationary and carrying the top pivot screw 27. The section 23 is detachably fastened to the base frame 12 for inspection of the mechanism.

As the center the disk 32lies upon the axis 27 of tion wheel 31 remains in driving contact with the friction disk when the frame is shifted to vary the speed-,of the friction disk, and as thevaxis of the friction disk and the friction wheel are parallel, andthe 'latter is edgewlse in driving contact with the former, the .arrangement produces a wide surface of contact, and the contacting surfaces move with the same relativespeed at all points. This is notthe case with an ordinary friction drive where the axes of the driver and the driven friction members are at right angles to each other. In this case, if the driver is a friction wheel engaging with its edge the face of a friction disk, the surface speed of the contacting surfaces nearest the axis of the 'disk is less than at ca bevel gear which Ais in-mesh with a bevel 52 is supported in bearings. 53 .on

points. farther from said axis.

The yshaft 33 driven roller 10 and theI shoe 1.1 'through certain instrumentalities to-be presently described.

The frame 15 is provided on its under side with a hub 42 through which extends a tubing 43 rising dfrom pending from the hub, with its lower end su ported by the housing cover 21. The tu 4is fastened to the hub by a set screw 44 ver the upper projecting' end of the tubing is fitted and secured by set screws 45, the neck 46 of a hollow bracket member 47, said bracket neck being also bolted to the frame 15. The bracket has a vertical bear- 48 'supporting the upper end of a vertishaft 49, on which shaft is mounted a The shaft gear 51 on a horizontal shaft 52.

the inside of the curved friction surby the friction gear-` ing hereinbefore described, voperates the g forheating the frame and also de" bracket 47 bya bolt 54a.

The roller 10. is supported at one end by vthe inner end of the axle 54 through a ball- Abearing 55, and at its opposite end, the roller projects a short distance beyond the corresponding end of the axle and hasa hub 56 into whlch ing pinned or otherwise made fast to the shaft. It will therefore be seen that the roller 10 rotates when the shaft 52 is in motion, said shaft being driven from the shaft 49 through the bevel gears 50 and 51.

The roller 10 is covered with a layer of soft absorbent material as usu'al and it is perforated, as shown at 5 7, through which the absorbed dampness in the-cover passes into'the roller so as to escape from the outer end thereof, said end being open except for the spokes 58 joining the hub 56 to the roller.

The bracket member 47 at the inner end of the roller'lO does not rise above the latter,

of a hollow tapered axle 54 fastened to the l the shaft 52 extends, the hub beand as the opposite end of the roller is also but if desired, the material can be folded,

doubled, or creased, etc.`and ironed this way.

The pressing or ironing `shoe 11 has 'a concave work-engaging face 59 to conform to the peripheral contour of the roller 10. A rear wall 60, end walls 61 and a flattop 62 complete being hollow to house a gas burner or any other suitable heating element 63. -The fumes escape through openings 64, in the top- 62, at the ends thereof, and air is adthe shoe structure, the samev mitted through a slot 65 at the bottom of f the rear wall 60. In the shoe is located a deector 66 to direct the heat to the workengaging surface 59 or to the top, 62, or both. The top 62 ish flat so that-a sad-iron I may be heated by being seated thereon as shown in Fig. 3. This provides a convenient means a sad-iron to be used for ironing garments and other articles or parts of such which cannot be handled by the machine.

On the frame 15`is pivoted,I as shown at 67 a frame 68 having operating connections with .the shoe 11 and. from the roller A10. of thef frame 68, is a hand release lever nected by a -link 71 vwith the shoe 1.1. The frame 68 is also connected to the shoe 11`by a link 72, the connection beingmade below the link 71. It willv therefore be .seen that the shoe 11 is carried toward or from the roller 10 when the frame 68 is swung, and the shoe may also be 4swung by operating the lever 0, the link 72 lnow functioning-as To the upper end to'swing the same toward pivoted as shown at 69 `70 which latter iscon- -68 is sw'ung the lever I 78 having its shaft 7 9 .Y 77, there is a swinging 'Suppen for ttes oe, the frame 68 Vremaining stationary. hen the frame 7 O and the `- links 71 and 72 swing bodilytherewith t'o'carry the shoe 11 toward or from the roller'10. lIt will be "understood that a link connection72 is made.

at each end of the,shoe.11l

Beneath the frame v15 isa' sitioned lever arm 73 which is connected 'to the frame purpose hereinbefore' described. The lever arm 73 obtains motion from the shaft 33. and other elements tov descr1bed,andthis shaft also through a gearing be presentlyy drives the shaft 49 which isv gearedto the shaft 52. for driving the roller 10.

The housin 20 has a step'bearing. 74 for the lower en of -the "shaft 49, and 'jon' said shaft is looselyfmounted a worin wheel 7 5 which is in mesh with a worm 7 6 on the shaft 33. On the shaft 49, abovethe worm wheel 75 is also loosely mounted a bevel gear 77 which is in mesh with a bevel gear supportedl in bearings on the housing cover is an eccentric "80 having its vstrap 81 'provided with a rod 82 having a yieldingconnection with a yoke 83, which latter is connected tothe lever arm 73. --The yieldingv connection between the rod 82 and the yoke 83 is made by a spring rod inside the yoke between the bottom'.por tion thereof and an abutment 8531011 the upper end of the'rod, said abutment being a nut so that the tensi'oiilof the spring may be adjusted. The yoke 8 3 of course seats Vslidably onthe rod 82. Thev motion of the eccentric 80, through its connections with the.

lever arm 73 swings the saine to rock Vthe frame 68, whereby the shoe A11 is ycarried toward and from the work onthe roller l0.

. The gear 77, through the gear 78 drives worin wheel 75. As stated hereiribefore,

the eccentric 80, and the drives the shaft 49.- the gear 77 and the worm wheel 7 5l are loose on the shaft 49, and hence a drivingconnectionmust be-.provided, which will now be described. v Y f Between the worm wheel 75 and the gear made fast on the shaft by a set screw or other 'means 86, the 4vhub 87 of a radial arm 88 having at its outer end an abutment in the form of an upstanding roller 89.. 0n the upper face of the worm wheel 75 is a similar abutment 90. On the at 91,-a dog 92, and on the under side of the gear 77 is lpivoted,as shown` at 93, a dog 94. The dog 92 has a depending flange92a which is in the path of the abutment 90. The arm 88 has an abutment 95 against which the dog 92 is held pressed by a spring 95a, vand on gear 77 is an abutment 94EL f or dog 94. The parts are so arranged that the shaft 49 is rotated when the worin wheel is in motion horizontally po- 68 for swingingthe same for the:

'spectively,

84 coiled around the' A104 as shown in Fig. 8,vv and as flange 92aofdog 92, and as said og is carried by the arm `88 and the latter is 'fast on l Shaft 49, a driving connection between the dog 92 and the arm 88- is established by thev engagement ofthe dogwith the abutment'95 Von said arm.

AV driving connection between the'arm 88 and the gear 77. is established by the -enf gagement of .the abutment 89 lon said. arm

.with a depending iange 96 on Vthe dog 94,`

carried .by said gear, said flange being in the path ofl this abutment, and the dog being pressed against the abutment 94,

At 97 and 98 are shown trip thedogs 92 and 94, said .fingers extending laterally from rocker arms 97a and 98a, re on a rocker bar 99y supported by bearing screws 01 carried by the frame 20.

The outer end ofthe arm 98a is connected,

02 to4 a foot pedal 03 supported by frame 12. A spring 04 normally holds the pedal '03 elevated,and with the pedal in* this position, in the pathof the'dog 92, whereas trip finger '98 is above and outoil the path ofthe dog by a rod v94 as shown in Fig. 8. The side arms of the the .pedal extend through an opening 05' inv base frame-12,v and the top of the openings limit the upward swing of the pedal. It will alsol be noted that v tioneddirectlyabove the arm 98a sothat it presses down'on said armon its downward stroke... On the Iupward stroke of the eccenthe shoe 11, through its connections with is swung away from the roller the eccentric goes down, the shoe is lowered as shown in Fig.v 9. .The connections between the ectric, the eccentric,

centric and the shoe are shown diagrammatically only in Figs. 8 and 9.

The operation lor the mechanism may be summarized as follows: A

Fig; 8 shows the .parts when the machine is not running. To start the machine, the motor 29 is started to set the worm wheel 75 in motion. down, which lowers the finger 97 out of the path of dog 92 so that whenthe abutment 90 reaches the flange 92a of said dog, the arm 88 is locked to-worm Wheel 75 `and the motion of .the latter i`s transmitted by thel arm to shaft 49 to rotate the roller 10. rl`he pedal isdep-ressed far enough to brin the finger 98 below and out of the p ath o? dog 94, and hence when the now swinging arm 88 ngers vfor the trip finger 97 is The pedal O3 is now pressed the eccentric 80 is positakes its abutment 89 in contact with the '.liange 96 of dog 94, the gear 77 also starts to turn and through the ear 78,v motion 1s transmitted to the eccentric 8O to lower the vshoe 11 to operative position, this'movement of the eccentric being downward. The pedal: 03 is depressed only long enough for the abutment 89 to reach the 'iange 96 of dog 94, because when the eccentric 80 goes downv f the shoe 11. The

www

it presses down on the a'rin 98 to again place the finger 98 in the path of the dog 94. The eccentric. arrives at 1ts lowered position after one half revolution of the arm 88, at the end of which the dog 94 is tripped by the finger 98 so that the motion of the gear 77 is discontinued and the eccentric 480 remains in lowered position, in Whichpositio'n the shoe l1 is down in operative position holding the material to be pressed against the roller 10.

The lowering of the arm 98El by the eccentric 80 also operates to maintain the position of the nger 97 out ofthe path of the dog 9 2, and hence the worm wheel 75 remains coupled to the arm 88 and the shaft 49 continues to turn to operate the roller 10. The

parts remain in this position until the piece of fabric being ironed is finished, where-l upon, the shoe 11 must be elevated and the roller 10 stopped for the insertion of another piece of fabric. This stoppage of the mechanism is effected by again depressing the pedal 03 far enough to take the finger 98 below the position it is held by the eccentric, as shown in Fig. 9, and hence out of the path of the dog 9,4, so that when the abutment 89 again reaches the flange 96, and gear 77 starts to turn, the eccentric 80 rises to elevate pedal 03 is depressed only momentarily, and then released to let the finger 97 come to tripping position, and by the time the shoe l1 has been elevated, the dog 92 has reached the finger 97 and the dog isnow tripped to break the driving connection for the shaft 49, so that the roller 10 now also stops.

The bracket vmember 47 carries a table bracket 06, a pivotal connection being provided, the same consisting of pivot screws O7 which enter the ends of the bolt 54a and provide a hinge connection to enable the table bracket to be dropped down, and it is held in horizontal position by a latch pin 08 ,v

adapted to be inserted into a keeper aperture in the bracket member 47. On one side of the table "bracket 06 is hinged, by links 09, a feed -table 010, and on the other sideis similarly hinged a leaf 011 having the shape of an ordinary ironing board, so that it may be used for finishing parts "of work, which are not reached in the ypassage of the same between the roller l0 and the shoe 11. The

ironing board can also be used for ironing` small pieces. The feed table 010 is held horizontal by a set screw 012 and the ironing board is held up by a prop 013. 4When the machine is not in use, the parts 06, 010 and O11 can be folded as shown dotted in Fig. 3, and covered by the hood 19, which latter keeps everything free from dust, and also disguises the appearance of the machine.

. For the sake of economy in construction, vthe machine may be built without the outside mantle 16 and the hood 19, as it still remains a safe and well-housed construction.
