To all whom it may concern:

' Be it known that I, WILLIAM A.

a citizen of the United States, residing at New York,-in the State of New York, have invented a new and useful Im rovem'ent in Ironing Machines, of which t e following is a specification.

to the end that steam may be evolved freely and the ironing performed rapidly; the provision of a plural roll machine having new and im' roved means of driving, supporting,

and ad usting the rolls; the PIOVIS'IOII of a new and improved type of domestic ironer; while further objects and advantages will become apparent as the description pr ceeds.

In the drawin accompanyin and forming apart of this applicationI ave shown certain physical structures in which my invention can be embodied although it' will be understood that these drawings are intended to be merely illustrative and not limiting.

Figure 5 is a detail of part of the roller driving mechanism; 1

Figure 6 is a fragmentary side elevation, partly in section, of the standards mounting a modified form of my invention;

Figure 7 is a fragmentary plan view of Fi re 6; I

igure 8 is a top view of the rod 52 and immediately adjacent pedal portions.

"In the embodlment of my invention there is provided a frame including a pair of standards 2, mounting a table 3, upon'which table is superposed a secondary pair of 3 is across section thro h the standards 4 carrying a U-shaped sheet metal plate 5, upon the front bight part of which carried by this table is a heated member 8 provided with any suitable heating means such 'as the gas'burner 9 fed'by a pipe 10. One part of the plate 5 bears a feed table 6 provided with a thin lip'7 projecting close to the heated member.

Beneath the burner 9 a guard screen 11 is hung, which extends full around the lower and si e arts of the hot plate 8.

'Pivote at 12 upon upstanding arms 38 wardly articulated levers each including the fulcrum arm 13 and forearm 13', pivoted at 15 on the former. Upon the extremities of the. arms 13' there is mounted a roller 14 and between the arms 13 intermediately of their length a roller 14" is mounted. The rollers have an endless chain connection by which they are caused to rotate with the at the rear ends of the plate 5, there are forsame eripheralspeed. The arm 13 is connect resilientlywith a lever 16 of the first class by a link 17, connected to a sliding collar 18 on the link seated against a spring 19 secured at the lower end of the link.

The lever 16 is fixed on a transverse fulcrum shaft 20 mounted beneath the table 3, upon which shaft a lever 21 is also fixed in alinement with .the lever 16 and forming therewith a bellcrank, the lever 21 being connected by a link 22 to a pedal lever 23, yieldingly supported by a spring 24 and pivoted adjacent the bottom of the frame at 25 in a U-sheafed bracket 26. The lever 16 is provid .with a latch member 27 enga g a rack segment 28, mounted on the tab e 3,

the teeth of the ratchet being so formed that .side of which is so curved and located as to fit snugly to the roller 14 when lowered, while the front side of the tter slopes graduallyupward to a level with Mounted .upon the table 3 there is a motor 29, connected by a belt 30 with a pulley 31,

on a shaft 32, the shaft 32 being mounted upon one lever13 with the pulley in such position that movement of the lever 13 will not affect the proper operation of the belt the plate 7. I

30. Upon the shaft 32 there is a worm 33 meshed with a worm gear 34 on the'shaft of the roller 14'-which carries a Sprocket 35 37" are provided. 7

driving. the chain 36' and thereby another sprocket 37 on the roller 14. At the other end of said rollers, like sprockets and 1 The hot plate 8 terminates to the rear of the roller 14 and a clearway 40 is provided through which fabrics may pass downwardly from the hot plate, and in the direction of the arrow 41, upon a sheet metal, or other suitable curved plate 42, the form of the plate being such that with the stiffness imparted by the ironing, fabrics will be projected forwardly thereon conveniently to the hand of an operator. This permits a single operator to both feed the machine and receive the finished work therefrom.

In the ,irdning operation, the work is placed upon the table 6, and fed beneath the roller 14, by which the pieces are drawn rearwardly, passin under the roller 14 and fixed by said stop, cause the upward movement of said lever 13, but, upon the downward movement of the lever 13 by the rod 17, when the roller 14' engages the plate 8 or work thereon the roller 14 will continue in itsdownward movement until it reaches the limit of the bottom of the recess 8, less the thickness of the work therein.

In the modified form shown in Figs. 6, 7,

and 8, the shaft 20 has fixedly mounted thereon three members, including two end arms. 44 and 45 and a central arm 46, the member 46 being a lever centrally mounted and rovided witha bifurcated end 46', the mem rs 44 and 45 being levers provided with respectively bifurcated ends 44' and 45. The shaft 20 is loosely mounted upon an internal ratchet segment 47, which segment is held from rotation b a shaft 48, which shaft 48 extends the 1111 length of the machine and is anchored to table 3. A pawl 49 pivotally mounted at 50 en ages in teeth 51 of said ratchet segment. '5 pawl is; a. right-angled bent-over extension of a vertical shaft 52, which as ivoted at k 50 upon its rotation engages and isengages the pawl from-the teeth 51. In order to'oompensate for the angular movement of the, ever- 46, to which the shaft 52 is connected,

a pivot 53 is rovided, .which between the bi urcations'46' of -t e lever 46.

Pivoted at 54 to the'standards 2 is a pedal 55 provided with an eye 56 and yieldmgly he said f ivot 53 is supported by a spring 24, said eye receiving the lower end of the shaft 52 as indicated at 57.

' Fixedly mounted on the shaft 52 there is a. rudder 58, which rudder is yieldingly held in alinement with the pedal lever 55 by a helical spring 59, but upon pressure of the toe in a clockwise direction as shown in FigureS, the shaft 52 is rotated, turning the pawl 49 from engagement with the teeth 51, which permits the spring 24 to lift the pedal 55 and lower the fixed levers 44'and 45, thereby pulling downward upon the lever 17. When the pedal is depressed, theratchet arm rides over the teeth 51' which are inclined for the purpose, whereby the said lever 46 will become set at whatever position it may be when downward movement of the pedal ceases, thereby regulatin the degree of pressure on the rolls 14 an 14 in stages suitable to various fabrics. For instance, the upper stop may give the greatest pressure; the second stop give a lighter pressure; the third sto is operative when the roll 14 is raised slig tly from the ironing bed for heavy work, and the lowest stop disengages the rolls entirely, which permits the irons to be cleaned easily, as preferably the predetermined lift of this lowest stop causes the front roll to be raised about thrfie inches, and the rear one about one 1110 It will be obvious that the modified form permits full control of the rod 17 b the foot alone, and in a simple and e cient manner.

-The space between the forward sloping part and the roller 14 may be termed a throat space, and the fabric passing from the forward part of the table will readily enter this throat without notable bending, obviating the need for a feed apron in advance of the roller 14, and without requiring the hands of the,operator to be brought near the throat.

Thelip plate 7 being very thin conducts but little heat from the plate 8, and radiates so much; that the feed table 6 is not detrimentally affected. The space betweenv the lip plate and hot plate is so extremely small in practice that work passes thereacross as though on a continuous surface, and the surfaces of the feed table and hot plate may be termed a practically continuous feed surace.

What I claim tobe new is:

1. In an ironing machine, a heated member supported in a substantially horizontal position, a frame pivoted to each end of said member, a pair of parallel horizontal rollers journ'aled in said frame and located above and in operative relation to said heated member and means for raising and lowering said frame, said framehavlng an articulation between said rollers whereby .frame at the sideawa the latter may exhibit a limited vertical movement relatively to each other. 7

2. A domestic ironing machine, compris-' ing a frame, a heated member supported by sa1d frame in a substantially horlzontal position, and two spaced, parallel, horizontal, padded rollers located above said heated member and in operative relationtherebo, bearing members for said rollers located at opposite ends thereof andpivoted to. said from the operator, means for driving sai 'rollers in the same direction, and pedal means for swinging said bearing members about their pivots so as to raise said rollers simultaneously away from said heated member.

I 3. a domestic ironing machine, a heatheated member and in operative relation.

thereto, means for revolving said rollers in the same direction, means for depressing said rollers with varying pressures while leaving said rollers free to movevertically independently-of each other in accordance with the thickness of articles passing therethrough, a pedal adapted when depressed to elevate both said rollers away from said heated member, and means for locking said pedal in' depressed sition.
