WILLIAM A. ZEIDLER, or" NEW YORK, n. Y.

Application filed December 13, 1920. Serial No. 430,312.

To all whom it may concern:

Be it known that I, WILLIAM A. ZEIDLER, a citizen of the United States, residing at New York, in the county of Bronx and 5 State ofNew York, have invented certain new and useful Improvements in Ironing Machines, of which the following is a specification.

This invention relates to improvements in ironing machines and the like, and has for its primary object to provide a simple and efiect'ive means for applying pressure to the feed rolls during the ironing operation, and quickly releasing and raising them from the work, the same means being adapted to lock said rolls in position during the operation.

applied pressure between them.

A. further object of the invention is to provide an improved hot-plate having a plurality of channels upon the ironing surface, each with a declining entry in order to insure positive feeding action to the rolls. A further object of the improved hot-plate is to provide means to apply a current of heated air from the interior of the plateto the work after being ironed in order to assist in the drying.

With these and other objects in view, the invention resides in the combination and arrangements of parts as will be hereinafter more fully set forth in the accompanying specification and drawings, in which Figure 1 represents an end elevatlon o my improved ironing machine;

Figure 2 represents an enlarged crosssectional view of the hot-plate of themachine with the rolls partly broken away,

shown in the ironing position;

Figure 3 represents an enlarged side elevation of the member- 22, with a tension rod and spring implace;

Figure 4 represents a top plan View of the machine with the.rolls and hot-plate broken away in order to show ating pedals, etc.

the oper- Figure 5 represents an enlarged rear ele-' vation of the hot-plate.

Flgure 6 represents an enlarged sectional View of a modification of the hotplate, with the rolls," in the ironing position and the frame of tlna machine indicated by dotted lines.

In. the embodiment of my invention herein illustrated, 1-1 represent standards or legs, arranged two at each end of the machine, connected by suitable cross braces '1 at the top and carrying the upwardly fac-.

ing heated member 2 and the feeding board 3 approximately level with the working surface thereof. This table is formed pref erably of hard wood, provided with an overhanging lip 3 of metal, approaching but. not touching the heated member 2. This heated member is made of metal and is' shown as formedlwith two longitudinalfrom the top by a gradual incline as shown.

The rear wall of the heated member 2' is here provided with a series of perfora tions, 2", the purpose of which will be shown later, and while this member may be heated in any approved manner, it is shown in this instance provided with a gas burner 4, connecting with a gas conduit 5. Beneath the burner 5 is a casing 6 formed of foraminous material which extends around and about the lower and'side parts of the hotplate 2 in order to prevent contact therewith, either by an article 1 being ironed or the operator.

Pivotally mounted uponbrackets 7-7 10- cated, one upon each end of the topof the machine at the side of the heated member opposite the feeding board, are jointed arms, each of which comprises two links, 8- and 9, respectively. Two cloth covered rolls,.10 and 11, respectively, are journaled between these arms, the centrally disposed shaft 10 of the roller 10 pivotally connecting the ends of the links 8 and 9, while the roller 11 is ..journale d between the free ends of the links 9 9 at either side of the machine.

Rotatably mounted upon a stud 7, of the bracket 7 at the left side of the machine, is a orm gear 12'meshing with a worm 13 the face of the worm gear 12, and is con:

- right ends of the shafts 10 and 11 of the nected by a sprocket chain 20 to a larger sprocket wheel 21 mounted upon the left end of-the shaft 11 of the roller 11. Upon the rollers 10' and 11 are mounted sprocket wheels 22 and 23, respectively, which'are connected by a sprocket chain 24 as shown It follows that the motor driving the pulley 16 will impart motion to the roller 11 through the sprocket chain 20, and thence to the roller 10 through the sprocket chain 24 connecting the sprocket wheels 22 and 23.

It will be seen that the compound arms carrying the rolls 10 and 11'may be flexed due to the pivotally connected links 8 and 9, and in order to limit this movement, each link 8 is formed with a squared projection 8 at the head, while the links 9 are formed with a lug or stop 9" upon the inner side as shown in Figure 4. The projection 8 and the lug 9 are in close proximity, so that the flexing movement of the links 8 and 9 is limited by the distance between the projection 8 and the lug 9.

A longitudinal shaft 25, journaled within the cross braces 1"1 at each side of the machine, carries permanently aifixed crank arms 2626, one at each end, and each of these crank-arms is provided with a pivotally mounted member 26, through which a rod 27 freely passes. The rods 27 are pivotally connected at their' upper ends with the links 9-9, at a point midway between the rolls 10 and 11, and their lower ends, beyond the member 26*, are each provided with a nut 27, set with a jam-nut 27". A.

coiled spring 28 is disposed upon the rod 27 between the nut 27 and the member 26, and another nut 27 is located upon the rod 27, above the member 26. Therefore power ap plied to the rods 27 from the cranks 26 to raise therolls 10 and 11 would be against the nuts 27, while power applied to the rods 27 to lower the rolls would be through the medium of the spring 28 against the nut 27. A lug 1 formed integral with the crossbrace 1, at eachend of the machine acts as a .stop for the corresponding arm after it passes the down center when the rollsare in pgsition. While in this position the ironing they are he depressed against the heated member with a force depending upon the tension of the spring 28, which in turn depends upon the. adjustment of the nuts 27 and 27".

Two arms 29 and 30, respectively, are also permanently mounted upon the shaft 25 at a point intermediate its ends and extending in op osite directions. necte with a pedal lever 31 by a rod 32, and

the arm 30 is connected with another pedal lever 33 by a rod 34. Thqpedal'lever 33 is provided, close to its front end, with a pivoted latch member 35 having teeth 35 adapted to engage a longitudinalbra'ce 1 at the front of the machine. The latch member 35 is held in contact with the brace 1 by a coiled spring 36, as shown. ,A shelf 37 is disposed between the standards 1-1, at a point below the hot-plate 2 in order to receive articles from the ironing rolls, and the shelf 37 is provided with a hinged extension 37. An electric switch 38 is mounted upon one oft-he standards 1, and is provided with an actuating lever 38 adapted to engage a'member 39 mounted upon and aflixed to one of the rods 27, so that when the rods 27 are moved upwardly to raise the rolls 10 and 11 from the ironing bed 2, the switch 37 The arm 29is con-.

will he opened, stopping the motor, but when the rolls are lowered to the ironing position as shown in the drawings, the switch 38 will be automatically closed and the motor will be started.

In the modification of the hot-plate or ironin bed illustrated in Figure 6, it will be notice that the contours of the channels formed on the ironing surface differ from those shown in Figure 2. In Figure 6 the channels M -40* of the hot-plate 40 are curved downwardly from the front of the plate, forming arcs of greater radii than that of the rolls, while the back of the first channel 405 conforms to the roll 11, curving upwardly to the surface of the plate 40, and the back of the second channel 40" curves downwardly at the rear edge 1 as shown. In this manner,a wide, gradually lessening curved threat is formed at the front of the rolls in order to facilitate the feed, the upwardly inclined rear channel 405 acting to atten out any full ness of the goods created durin the assage rtion of the first of the goods through the first 0 anne The Y abrupt downward curve 40" permits the oods to assume a natural curve over the fiobplate 40 downwardly to the receiving shelf. This entirely eliminates any wrinkling or fullness t at may be caused in folded articles passing through the channels 40-40. The rear walls are provided with a series of rforations 40, similar to those shown'in 11E: ures 1 and 5.

In operation the article to be ironed is spread upon the shelf 3 and introduced into the first channel 2 of the hot-plate 2. The rolls 10 and 11 are then lowered'to the ironing position by releasing the pedal 33, the

'120 hot-plate 2, as shown in Fig switch 38- being closed by the downward movement of the rod 27. -"Ihis brings the arm 26 only part way down but leaves the rolls and 11 resting on the heated member or'ironing board solely by their own weight mitted by the stops 8, 9. The articles are rapidly smoothed and dried not only by this pressure but by being drawn over the rounded portion of the heated member or ironing bed which rises between the two rolls. This conformation of the bed combined with its wide extent produces a quick drying and since the evolution of steam is permitted by the small diameter of the rolls sprin and the considerable distance between them the machine operates very rapidly. In case a higher degree of pressure is desired. than is produced merely by the weight. of the rolls, the second pedal 31, is depressed t the position shown in Fig. 1, which moves the arms 26 past their dead centers until they engage the stops 1". The rods 27 being attached to the mid-points by the links 9, the pressure of the rolls is equalized while permitting them to yield against the The article after ironing passes backwardly over the hot-plate 2 and over its rear wall, the perforations 2 of which permit the direct application of heated air from the burner 4 to assist in drying the article ironed, which falls to the shelf 37.

The rolls 10 and 11 are raised by foot pressure applied to the pedal 33 acting on the rod 34, the arm 30, shaft 25, arms 26, and rods 27 connecting with the'links 9-9 of the articulated arms carrying the rolls. As the pedal 33 is depressed, raising the rolls, theteeth 35 of the latch member 35 engage the .mlbrace 1, holding the rolls in the raised po-' sition, the switch 38 being opened by the lipward movement of the rod 27. When it is desired to lower thev rolls, a quick downward thrust upon the pedal 33 is suflicient to. dis engage the latch member 35, or the pedal may be depressed slightly and the latch member disengaged by the toe or other meansg, When either pedal is depressed the 56 other is always elevated. Pedal 31 is locked in depressed position by the movement of I the arms 26 past dead center, but is unlocked and raised by depressing-the pedal 33. I claim:' 1. In an ironing machine, a roll, a plural ity of pedals, means inter connecting said roll and pedals adapted for raising and lowering the roll upon a downward and upward movementof one of the pedals, and meansv connecting with the first means for increasing the pressure upon the roll upon a downward movement of another of said pedals.
