UNITED STATES PATENT FISE,

WILLIAM A. ZEIDLER, 0F NEW YORK, N. Y.

IRONING- MACHINE.

Application filed January 5, 1921.

To all whom t 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 State of New 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 simplel and effective means for applying pressure to the feed rolls during the ironing operation, and for quickly releasing and raising them from the work; the same means being adapted to lock said rolls in position during the operation.

Another object of the invention is to provide an improved means of mounting and heating a mangle roll. A further object is to provide novel means to supply heated air from the interior of the roll to the burner. A still further obj ect is to give an improvement in relation to the feed table, heated roll, and padded drums, whereby finely iinished work will be quickly produced.

With these and other objects in view, the invention resides in the structure, combination and arrangement of parts as will be hereinafter more fully set forth in the accompanying specification and drawings, in which- Figure 1 represents a side elevation of a machine embodying my invent-ion,

Figure 2 is a fragmentary top view partly in section of cylinder mounting and heating means,

Figure 3 is an enlarged side elevation of the rock shaft and pressure arm, with a tension rod and spring in place,

Figure 4 is atop plan view of the machine with the rolls broken away in order to show the operating pedals, etc.,

Figure 5 is an enlarged side elevation of the rolls with one side of the frame and connections removed.

Figure 6 is an enlarged detail sectional view of the control pedal,

Figure 7 is a detail perspective of the chimney.

In the embodiment of my invention, herein illustrated, 1-1 represent legs located at each end of the machine, and la, 1a, represent cross bars, upon which is journalled a rotary shoe or drum 2. A feed shelf 3 is provided at the front, formed preferably of wood, and having an overhangng lip 3 of metal,

Serial No. 435,211.

closely approaching but not touching the drum 2. The drum is a hollow cylinder having spiders 2a at the ends fixed upon a foraminate hollow shaft A which serves as a combined journal and burner. The shaft projects beyond the drum at each end and is there supported upon roller bearings ta moving in a suitable raceway 4b, on bars 1a of the frame. rlhe foramens of the shaft are within the drum only. 'I'he shaft is open at the left end, and the raceway there is closed at the outer side by a cap plate 5 spaced from the end of the shaft suitably to admit air entering through the bearing. In the cap plate a nozzle 6 is provided arranged to direct gas axially into the shaft. A fuel conduit (ifL leads to the nozzle. The jet from the nozzle serves to draw air into the burner through the bearing, keeping the latter cool, and forming a properly com* bustible mixture.

Pivotally mounted upon brackets 7 7 located, one upon each side of the top of the machine at the rear, are jointed arms, each of which comprises two links, 8 and 9, respectively. rIlwo cloth covered rolls, 10 and 11, respectively, are journaled between these arms, the centrally disposed shaft 10a of the roller 10 pivotally connecting the ends of the links 8 and 9, while the shaft 11El of the roller 11 is journaled between the free ends of the links 9 9 at either side of the machine.

Rotatably mounted upon a stud 7a, of the bracket .7 at the left side of the machine, there is a worm gear 12 meshing with a worm 13, mounted upon a shaft 14, which is journaled within the member 15 as shown. A grooved pulley 16 is mounted upon the outer end of the shaft 14C, and is connected by a belt 17 to the pulley 18a of an electric motor 18. A drive wheel 19 here shown as of the sprocket type is centrally mountedupon the face of the worm gear 12, and is connected by a chain 20 to a larger sprocket wheel 21 mounted upon the left end of the shaft 112L of the roller 11. Upon the right ends of the shafts 1()a and 11*1 of the rollers 10 and 11, are mounted sprocket wheels 22 and 23 respectively, which are connected with a sprocket chain as shown. It follows that the motor driving pulley 16 will impart motion to the roller 11 through the sprocket chain 20, and thence to the roller 10 throu h the sprocket chain 24 connecting t e sprocket wheels 22 and 23.

It will be seen that the compound arms carrying the rolls l() and ll, may be flexed due to the pivotall connected links 8 and 9, and in orde-r to limit this movement, each lilik 8 is formed with a squared projection 8TL at the head, while the links 9 are formed with a lugor stop 9y upon the inner side as shown in Figure The projection 8 and the lugl tifL are in close proximity, so that the upward movein .at of the link 9 relative to the link 8 is limited.

A longitudinal s iaft 25, journaled within the lower cross braces lf2-l. at each side of the machine7 carries permanently aiiixed crank arms .2G- 267 at each end, and each of these arms is provided with a pivotally mounted wrist member 2G7 through which a rod 27 freely passes. The rods 27 are pivotally connected at their upper enc-rs with the links 9 9a at a point midway between the rolls l0 and lll, and their lower ends, beyond the member 26, are each provided with a nut 2TLL and a jam-nut 27". l coiled spring 28 is disposed upon the rod 27 between the nut 2'?" and the member 25a, forming' a yielding means for transmitting pressure from the wrist to the rod. A nut 2T is located upon the rod 273 above the wrist by which a positive lift is provided. Lugs lb formed integral with the cross braces laa on each side of the machine serve as stops for the crank arms after they pass the lower read center iirlowering movement, lowering the rolls l0 and ll. Due to the spring 28 they become ),f'ieldingly locking on the ironing bed.

rlwo crank arms 29 and 30 respectively, are fixed upon the shaft 25, midway of the machine7 extending in opposite directions. The crank 29 is connected vith a pedal lever 43l by a link 32, and the crank 30 is connected with another pedal lever by a link 34. rl`he lever 38 is of channel iron with its bigrht portion at the upper side. The lever has pivoted therein an upstanding forwardly leaning latch notched at the upper front part 36 to receive the upper rearwardly turned flange of a channel bar cross brace between the two front legs of the frame. The latch has slidable thereon a release member l0 having an inclined part al which on upward movement will the lower flange of the bar 34 and ward the latch rearwardly until the notch 36 is clear of the upper flange. This action is effected by pressing` ay button 42 close to the foot plate 83a on the pedal lever 33.

rlhe latch release comprises a strap of metal having its upper end bent at right angles to its major part and apertured to slidably receive the latch. lmmediately below the apertured part it is bent forwardly and then rearwardly at oblique angles to form a il-shaped part 43, the upper side of which may wipe against the flange when the release is moved upward. From this inchined part the strip is extended downward through the lever lwhich is suitably apertured to hold its lower part slidably. The lower end la of the strip is recurved forwardly and apertured to receive the rear end of a small lever between the sides of the lever 'he outer end of the lever being closely adjacent the pedal plate 33 and attached to the stein of the button e2. lit desired a spring e6 may be employed to bear the latch i nto operative position. I

A shelf is disposed between the standards lwl. at a point below the drum 2 in orderV to recel/e articles from the ironing; rolls7 and the shelf 37 is provided with a hinged extension 37". An electric switch 38 is provided at the left of the frame having an actuating' leverl 38 connected with a member 39 upon the adjacent rod 27, so that when the rolls l() and ll are raised the switch 38 will be opened stopping the motor, but who the rolls are lowered to the ironing;l position as shown in the drawings, the switch 3S will be automatically closed and the motor will be started.

ln operation, the rolls l0 and ll are first released by the pedal 33, and the article to be ironed is next placed upon the shelf 3 and extended to the roll 2. rEhe rolls l0 and ll. are then lowered to the ironing` position by foot pressure applied to the pedal 3l acting;i on the rod 3 2. crank 299 shaft 25, cranks 26, spring 28e and rods 27 connecting` with the links 9-9 of the articulated arms carrying the rolls7 the switch 3S havingl been closed by the downward movement of the rod 2T. rlhe rolls l() and il are thereby held yieldim pressing upon the work, pressure in both rolls beine` equalized. Full stroke of the pedal 3l carries the wrist 26a beyond the dead center and the rolls are looked in ironing,- position without further effort by the operator.

The article after ironing passes backwardly over the roll 2 and falls to the shelf 37.

The rolls .l0 and il are raised by foot pressure applied to the pedal acting on the rod 34 the crank 30, shaft 25, cranks 26 and rods 2? conim f ina* with the links 9 9 of the articula1A .Y arms carryingV the rolls. Asthe pedal 33 is de resseth raising the rolls7 the notch of the latch member 35 engages the Aflame ld holding' the rolls in the raised position, the switch 38 being at the same time opened by the rod 27. When it is desired to lower the rolls, a quick downward thrust upon the pedal 33 is sui'icient to disengage the latch member 35, or the pedal may be depressed slightly and the latch member disengaged by the toe or other means.
