AXEL ROBERT GUSTAFSON, OF CHICAGO, ILLINOIS.

IRONING-MACHINE.

To all whom it may concern:

Be it known that I, AXEL ROBERT Gus- TAFSON, a citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented a new and useful Ironing-Machine, of which the following is a clear and accurate specification.

- My invent'bn relates particularly to the class of laundry machines which are used for'ironing shirt bosoms, collars, cuffs and the ,like' and themachine which I employ differs. essentially in form from those customarily used.

It is desirable in ironing machines that the construction be such that there is no danger of catching the articles opera-ted upon in the working parts of the machine and damaging them, otherwise great care has to be taken by the operator to avoid such results. In .my invention this difficulty is entirely avoided'inas much as the operating or driving parts ofthe machine are placed on the oppositeside of the frame or standard from the rollers and the ironing board. The roller or rollers are journaled in adjustable bearings, while theironing board, forming the segment of af icircle, is passed under the said roller or rollers, thereby rev'olvingsame. The freedom of movement is accomplished. by a novel beltshift' device, whereby I am enabled to reduce t e movement of the segment, which constitutes the ironing board, to a few inches, which allows me to pass it rapidly back and forth under the roller should the article to ,be ironed and placed upon the ironing board make such proceeding desirable. .The pressure exerted y the rollers upon the article placed upon the ironing boardcan be increased or decreased by means of springs resting upon the bearings wherein the rollers revolve. In

' this way a pressure is obtained which is at the same time of a yielding nature so that over the entire inner surface,

uniform high temperature throughout the rollers.

These various objects as set forth above are accomplished by the novel construction of the machine illustrated in the accompanying drawings, in which a Figure 1 is a complete side elevation of the machine, showing all its principal part-s; Figs 2, is a plan view in which the ironing rollers are more particularly shown; Fig. 3, is a sectional plan View at lines AA of Fig. 1; Fig. 4, is a detail of the shirt stretcher with a sectional view of the stretcher bar; Fig. 5, is a detail of the yoke and neck band clamp; and Fig. 6, is adetail of the saddle, lookin at it from below and showing the methoIl of securing the'removable ironing boards. Fig. 7 is an enlarged, fragmentary, longitudinal section of the ironing board and saddle plate therefor.

Similar letters refer to like parts throughout the several views.

The frame A, which has the shape of a goose neck, carries the ironing device indicated as a whole by B. The n'oning board C is carried byareinforced rocker" arm D, which latter is pivoted in the foot of the frame A, where is also located the mechanism which moves the former. A belt shifting device E reverses the movement automatically; in addition thereto it can be reversed at will by foot power; These are the principal parts of the machine, the functions of which will. now be explained in detail The frame A 'is secured. to floor late 10 which is placed upon the floor an suitable belt connections are made to tight and loose pulleys 1. A b'elt shifter 2, which is supported in suitable brackets 2 is used to shift belt 3 from the loose upon the tight pulley and vice-versa. The pulleys 1 are secured to power shaft 4 in the customary manner. The latter revolves in bearings 5' which are a part of the special pulley frame 5. This frame isfitted to the gooseneck of machine frame A and secured thereto by bolts 5 v Power" shaft 4 carries one pulley'6 between bearings '5, which is keyed to the shaft 4. At the lower end of pulley frame 5 a driven shaft 7 is similarly located. This shaft is rovided with a series of tight and loose pul eye which correspond with the pulley placed on the power shaft 4. The. belt connection between the pulleys on power shaft 4' and driven shaft 7 is established by one straight belt 8 and one twisted belt 8. By shifting the two belts so that at one time the straight belt and at another time the twisted belt runs on the tight pulley 6 the movement of the driven shaft is reversed. This reversing movement is, as is well known, not new and reference to it is made merely for the purpose of identifying it with the novel features embodied in the shifting device E, which is located in the foot of frame A.

Driven shaft 7 is provided with a pinion 7", which is in gear connection with gear wheel 9, the latter of which is secured to operating shaft 9. This shaft is journaled in bearings 10, which are substantially bolted to floor plate 10, and its side thrust is taken up by collars 9 which latter are secured to shaft 9. .The opposite end of shaft 9 is provided with worm 9 which is in gear connection withthe toothed segment 11 of rocker arm D.

Rocker arm D swings in a recess 12 in the foot of frame A, as shown in the section Fig. 3. In the legs 12 at the sides of this recess, arm D is swingingly supported by means of axle 13, which is secured to the rocker arm by pin 13. The faced bosses 12 prevent side play during the swinging movement of arm D within the recess.

Two brackets 14 are secured to floor plate 10 in front of the machine. In the bearings 14 of these brackets rotates axle 15, being secured therein by collar 15 and nut 15 A short lever 16 is secured at one end to axle 15 and pivotal connection betweenthe other end of this lever and the hori- Zontal shifter arm 16 is established by means of pin 16 This shifter arm is provided with a fork 16 on its other end, wherein is placed the upright connecting arm 17, being connected by pivot 17 therewith. The short end of connecting arm 17 is pivoted by means of pivot 18 in upright bracket 18, which latter .is'secured to the floor plate 10. Connecting arm 17 is bent sidewardly toward the center of the frame where it meets the horizontal belt shifter 19, which is connected with the fork -17 by a pin 19. A slot 17 allows the required play for the pin 19 during the swinging movement of arm 17. Shifter arm 19 slides within apertures 5 with which pulley frame 5 is provided and carries shifter prongs 19 in proper relation with the position of belts 8 and 8.

The belt shifting is accomplished automatically by shifter pins 11 which are secured in their proper position in segment 11. These pins engage shifter lugs 16 which are adjustably secured to shifter arm 16, during the rocking movement of arm D as will be apparent. The treadle 15 is attached to axle 15 outwardly of bearing 14 to the right hand of the machine. By means of this treadle belts 8 and 8 can be shifted at will,

whereby the rocking movement of arm D isplaced fully within the control of the operator.

Rocker arm D carries on its upper end shield 20, which is secured to. it by bracket 20 and bolts 20 Above the shield, the arm obtains the form of a saddle 21, upon which the removable ironing board 22 is secured. The board is provided below with a square boss 22, the surface of which is fitted to the square saddle surface 21, so that the board 22 forms the arc of a circle described on pin 13 as an axis. Lockers 23 are secured to the under side of board 22, they are provided with 'a boss 23, the height of which corresponds with the thickness of saddle plate 21 and swing around cap screws 23 Dowel pins 22 which are driven into the underside of square boss 22, fit into corresponding holes in saddle plate 21, whereby the ironing board is always placed in its true position. These dowel pins may be placed in the saddle plate 21 instead of in the boss 22, in which case the latter must be provided with the corresponding holes. When the ironing board is placed upon the saddle, it is only necessary to swing lockers 23 over saddle plate 21.

The top of the ironing board 22 is padded with suitable material to form a cushion for the article to be ironed. This padding is hooked in place upon hooks 24, which are covered by a frame 24 the latter of which is secured to the board by round head screws 24 When a shirt isplaced upon the ironing board, it must be held thereto. This is done by placing the neck band of the shirt in the circular cut-out 25 of the ironing board and a special neck band clamp, of which a detail is shown in Fig. 5, is used to hold it-in place. The neck band clamp is located upon the shield 20, below the circular cut-out 25, and fastened to the former by .brackets 26, which serve at the same time as the bearings wherein the .clamp rod 26 rotates. are placed upon the rod and are secured in the desired position by set screws 26 A crank 26 is fastened to clamp rod 26 and 1 connection between the latter and the clamping crank 27 is established by a connecting 115 piece 27 The, axle of clamp crank 27 is journaled in the bracket 27, which is also secured to shield 20, and carries on its free end the crank handle 27 These cranks 26 and 27 draw the clamps 26 against the yoke 120 and neck'band 'of the shirt on the ironing board and by swinging connecting piece 27 upon the dead center of clamp crank 27,

secure same in that position. The shirt is now held fast to the ironing board by its yoke 125 and neck band, it must now be stretched over the ironing board without folds or wrinkles. This is accomplished by the bosom stretcher as shown in Fig. 4. The stretcher rod 28 is journaled in brackets28, which are also 130 Clamps 26 the latter.

located on the shield 20 on the lower end of A half round stretcher clamp 28 is pivoted to the rod at .one end so that it may be swung up into the dotted position. The clamp locker 29 is located on the other end of the rod and is movably secured thereto by pin 29. The nose 29 of clamp locker 29 reaches under the rod 28. A spring 29 .rests upon the nose, whereby the locking hook is forced over the half-round stretcher clamp 28. The shirt is placed between rod 28 and clamp 28 the latter is pressed down and as soon as the locking end has passed the hook of locker 29, the latter engages over the clamp and locks it. For the purpose of stretching the shirt, the stretcher rod 28 .must be rotated in the required direction whereby the shirt is drawn tightly over the ironing board. When the shirt has been stretched in this way, it is held in this condition by the sharp nose 30, which is fastened to rod 28 and which engages slot 30 of spring 30 the latter of which is fastened to bracket 28, though obviously any number of noses and corresponding slots may be provided. The collar 30 is for the purpose of adjusting the side-play of rod 28.

When the ironing board 22 is swun under the ironing rollers 31, these rollers will be rotated in their hearing blocks 32. The latter are located in a special bracket 32, which is rigidly bolted to the goose-neck of frame A by bolts 32". The bearing blocks 32 are fitted into the housings 33, wherein their height can be regulated by adjusting screws 33 from below. The yielding pressure, whichfo'rces the rollers down upon the ironing board, is provided by a pin 32 which pin is a part of the bearing block 32 and extends into spring bracket 34. A spring 34 is housed in this bracket and rests upon the pin 32 The pressure may be increased by hand screws 34 whereby the spring can be compressed to any desired compression. The spring bracketv 34 is secured to the box part 33 of bracket 32 by cap screws 34 It will thus be seen that the rollers may be forced down upon the ironing board with more or less ressure, the degree of which can be readlly adjusted. The rollers 31 are hollow and the heating device 35, which is shown in Fig. 2,- is inserted into same through the brackets 35 and extend throughout the envice is stationary with the brackets 35 while the rollers revolve, and as the heat is produced by a mixture of gas and air, which escapes from the heating tube, a flame is pro ,duced which strikes the complete inner surface of the ironing roller, and provides thereby a uniform and high temperature throughout its ironing surface.

During the process of ironin the rollers may act repeatedly and inuidli succession upon particular plaits or fo ds in the shirt bosom or other articles by theuse of the foot attachment of the shifter device.

It will be seen that the construction of the machine maybe altered in minor details without departure from the spirit and the scope of my invention.
