SPECIFICATION forming part of Letters Patent No. 717,568, dated January 6, 1903.

Applies@ ned Marat 26, 1902.

To all whom, t ina/y concern:

Be it known that LHENRY H. GrRAACELad citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Ironing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates. to improvements in ironing-machines and to such as are adapted for the ironing of the wristbands and neckbands of shirts or like garments.

It consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents an end elevation of the ironingmachine, the power-receiving pulley thereof being removed. Fig. 2 is a side elevation of the machine. Fig. 3 is an elevation of the opposite end of the machine from that shown in Fig. 1. Fig. 4 is a detail sectionai view through one of the ironing-rolls andthe mechanism supporting the same. Fig. 5 is a longitudinal sectional view through the paddedy pressure-roll.

The ironing-machine embodying this invention is' formed kwith a frame made up of two standards 1 and 2, connected by a brace bar or plate 3 and further braced by a tie or brace rod et. One of the standards, as 1, carries a power-receiving shaft 5, journaled in the said standard and carrying at its outer end fast and loose pulleys 6 and 7 which are adapted to be connected up by suitable belting with a proper source of power. The inner end of the shaft 5 projects a short distance beyond the standard 1 and carries a pinion 8, which meshes with a gear-wheel 9, secured to the end of a counter-shaft 10. The counter-shaft 10 also finds a suitable bearing in the standard 1 of the frame, its outer end being provided with a pinion 11, which in turn meshes with and actuates a gear-wheel12 upon the outer end of a pressure-roll shaft 13.

The pressure roll shaft is considerably longer than either the shafts 5 or 10, so that it may project beyond the standards 1 and 2 of the frame at each end of the machine.

Serial No. 100,123. (No model.)

One end of said shaft carries the pinion 12 just outside the standard 1, while the other end carries the pressure-roll 33 just outside the other standard 2 at the opposite end of the machine. Arranged in suitable relation to the shaft 13 are two other shafts 17 and 18, carrying ironing-rolls 29 and 30, which act in conjunction with the pressure-roll just men tioned. The shafts 13, 17, and 18 are mounted in the frame of the machine in a similar manner, one end of each shaft being secured in a cylindrical sleeve or box 19, which is formed with oppositely-projeeting trunnions 20, as clearly indicated in Figs. 1, 2, and et of the drawings. The bearing-boxes 19 permit the shafts 13, 17, and 18 to rotate properly and yet allow for movement of the said shafts in a plane at right angles to the axes of the trunnions 20. The boxes 19 are arranged in apertures formed in the frame-standard 1. Each ofthe said shafts 13, 17, and 18 extends through a sliding bearing-box 21, mounted in the standard 2 of the frame. These bearingboxes 21 are formed with liat sides,which bear against the guiding sides of slots 22 in the standard 2. By reference to Fig. 3 it will be seen that the movement thus arranged for the shafts 13, 17, and 18 is such that the rolls can be readily brought together or that by separating the said shafts the rolls will be correspondingly separated. The shafts 17 and 18 carry pinions 15 and 16, respectively, which mesh with a gear 14 on the shaft 13 and receive motion therefrom.

- The boxes 21 of the shafts 17 and 18 are normally pressed inwardly by means of springs 23, which are inclosed in casings 25, formed upon the standard 2. A set-screw 24 in the end of each of these casings is employed to regulate the tension of the said springs. The sliding box 2l of the shaft 13 is -held in position and adjusted by means of a cam 26,which is pivoted between lugs 27 on the standard 2 and is provided with a lever-arm 28, as shown in Figs. 2 and 3. The cam is preferably formed with a circular head eecentrically pivoted,so that the retractile pressureof the pres sure-roll will tend to hold the cam in one position or the other without other locking means. The lever arm or handle of the cam engages the frame of the machine or a stop thereon, which limits the movement ofthe IOO cam. The bearing-box 2l, carrying the shaft 13, is forced inwardly, so that the pressureroll 33 is forced against the ironing-rolls 29 and 30. By lowering the lever-arm 23 the cam 26 will be so moved as to permit the pressure-roll to fall away from the ironing-rolls 29 and 30.

A knife or curved plate 35 is mounted in such relation to the ironing-rolls as to bear at its opposite ends against the peripheries thereof, the said knife being supported upon the standard 2, as clearly illustrated in Figs. 2 and 3. This knife-plate occupies such a position that it will prevent the cloth of an article being ironed from adhering to one of the ironing-rolls and will guide the said article properly between the other ironing and the pressure roll.

The ironing-rolls 29 and 30 are made practically alike, the only difference being that the roll 30 is preferably slightly larger in diameter than the roll 29, so that its periphery will travel a little faster than the periphery of the roll 29 and will assist in keeping the material of the article ironed smooth and without folds or wrinkles and will have a polishing action also upon the surface of said material. Each of these rolls is made hollow, as shown in Fig. 4, the outer end being open to receive a burner 31, by which the said roll maybe heated. The inner end of said roll is preferably conical in shape and is formed with apertures 32 for Ventilating the interior of the roll.

The pressure-roll 33 is preferably a padded roll, its surface being covered with several layers of suitable fabric, and the said roll is preferably smaller than the ironing-rolls, so that the said ironing-rolls will move faster than the pressure-roll in their action upon the article being ironed. The pressure-roll 33 is also made longer than the ironing-rolls 29 and 30, so that the material at the end of the roll, as at 34, which projects beyond the ends of the rolls 29 and 30, will be left in a raised condition, the remainder of the padded portion of said roll being much compressed with relation thereto, because of the pressure of the ironing-rolls. This shouldered portion 34 of the padding of the pressure-roll is found to be very advantageous in the ironing of the wristbands and neckbands of shirts, since it makes it possible to iron such bands without flattening or crushing the adjoining fulled or gathered portion of the fabric.

The gearing connecting the pressure-roll and ironing-rolls is so proportioned that the ironing-rolls travel faster than the pressureroll, so that the tendency is for the ironingrolls to flatten out or straighten out any wrinkles or folded portions of the garment being ironed and at the same time to give a considerable polish to the exterior thereof. The curved knife-plate 35 being arranged to scrape against the ironing-roll 29, as shown, prevents the fabric from adhering thereto and assists in giving the parts a proper circular form. In use also the roll 30 is heated somewhat hotter than the roll 29, since the said roll 29 engages the fabric to be ironed while it is more or less moist and if very hot would be apt to burn or scorch the same, While the rollV 30, engaging the said fabric after it has been considerably dried by the said roll 29, may be made considerably hotter without danger of scorching the material operated upon.

In operating the machine power is applied to pulley 7 and transmitted through the train of gearing described, so that the ironing-rolls are rotated faster than the padded or pressure roll. The lever 28 is lowered for the insertion of an article to be ironed and is then raised to throw the padded roll into contact with the ironing-rolls, which are previously heated, as described. The tensions of the springs 23 are adjusted to give the desired pressure upon the wrist and neck bands. The articles to be ironed are fed between the padded roll and the roll 29 and are then guided by the knife 35 between the said padded roll and the second or nishing ironing-roll 30. The article operated upon will then be ironed and polished and given a proper circular form.

I may, if desired, employ any suitable shield over the gearing and rolls and., prevent the fingers and clothing of the operator from being caught by any of these parts; but they may be made of any ordinary form, and I do not illustrate or claim'the same.

The parts of the device are comparatively simple and yet easily within the control of an operator at all times. It will be apparent, of course, that I may make minor changes in the form or structure of the parts without departing from the spirit of the present invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An ironing-machine provided with a suitable frame, a padded pressure-roll mounted therein, hollow heating rolls or drums arranged to rotate against said pressure-roll, the pressure-roll having a periphery of the same diameter throughout, but being longer than the heated rolls so that its padded surface will be squeezed around the edges of the said heated rolls for preventing the crushing or flattening of the gathers or folds of the garment adjacent to neck or wrist 'bands and the like, substantially as described.

2. An ironing-machine, comprising a suitable frame, a pair of hollow heated polishingdrums yieldingly mounted in said frame, a padded pressure-roll arranged to bear against the peripheries of the polishing-drums, a pivoted and a sliding bearing supporting the said pressure-roll, a cam mechanism adapted to engage the sliding bearing of said roll, comprising a circular head portion eccentrically mounted and bearing with its periphery against the said sliding bearing,and a lever for turning the said circular head, the said lever engaging a stop for limiting the movement of IOC) IIO

the cam, the head being so arranged with respect to its pivotal point that the retractile pressure of the pressure-roll will tend to hold the cam in one position or the other Without other locking means, substantially as described.

3. An ironing-machine, formed With ironing-rolls and a pressure-roll, the ironing-rolls being 0f larger diameter than the pressureroll so as to move more rapidly over the garment or other article being roned than does the pressure-roll, shafts mounted in a suitable frame and projecting beyond the end thereof, for carrying said rolls, journal-boxes at the ends of said shafts opposite to the rolls, said journal-boxes being pivotally mounted in apertures in the frame of the machine,
