IRONING- SPECIFICATION formingpart of Letters Patent No. 472,954, dated April 12, 1892. Application iiled October 15, 1891. 4Serial No. 408,802. (No model.)

To ZZ whom, it may concern:

Be it known that I, CHARLES E. QUARN- STRM, a subject of the King of Sweden and Norway, residing at Chicago, in the county of Cook and State of Illinois7 have invented a new and useful Improvement in Ironing-Machines, of which the following is a specification.

My invention relates to an improvement in 1o ironing-machines of the class employed more especially for ironing and polishing shirt-bosoms, collars, and cuffs, andv which involve as their main operating parts a hot revolving ironing orpolishing roller and a support for I5 the article to be ironed reciprocating below and in contact with the ironing-roller.

AMy objectis toprovide a machine of the above character of a simple, durable,l and comparatively inexpensive construction and l zo which shall be eminently effective and quick in its operation.

In the drawings, Figure l is View of myimproved machine in side elevation; Fig. 2, a central longitudinal section of the same; Fig.

z5 3, a section taken on line 3 of Fig. l and viewed in the direction of the arrow, and Fig.

4 a sectional plan view taken on line 4 of Fig. l and viewed in the direction ofthe arrow.

A represents the frame of the machine, comprising two sides or castings t Z', connected together by cross-bars t2.

B is the drive-shaft, mounted in and extending through bearings s s in the frame A. The shaft B carries at one end the fast pulley 3 5 r and two loose pulleys r', and at its opposite end it is provided with a pinion q.v Above and somewhat back of the shaft B is a shaft vC in bearings in the frame A and carrying outside the frame a cog-wheel 0,*which meshes 4o with the pinion q. Between its bearings the shaft .C carries a friction wheel or drum C', theouter circumference of lwhich affords a n friction-surface.

D is a swinging frame comprising side bars n n, connected together at their end portions by cross-bars n. beted in their adjacent faces to afford a grooved track n3, as shown in Fig. 3. The frame D is supported on arms or brackets fn?,

The side bars n n are rab-v rigid therewith and-whichare pivotally mount- 5 o ed at their lower ends on the shaftCbetween the drum C" and sides of the frame A. Journaled in bearings m, extending downward from the sidebars n of the frame D, is a roller m. Extending downward from the center o`f the cross-bar n', nearest the front l of themachine, is a lug Z, threaded at its lower end, and extending downward from the 'cross-bar Z2 at the forward end of the frame A is a lug k, threaded alongitslower end 6o portion. A bracket t" of the angular shape shown in Fig. 2 is provided near its opposite ends with openings which t, respectively, closely, but loosely, over the lugs Z lc. Interposed between the bracketiand bar n on the lug Z is a cushion Z, which may be of rubber, as indicated by Athe drawings, or any convenient form of spring, and the bracketz'is maintained against the cushion by a nut Z2 on the threaded end of the lug Z. lug k and confined between the bracket 1I and cross-bar t2 is a spring k. Below the bracket fi on the threaded portion of the lug Za is a crank k2. Turning of the crank Zazin one direction causes it to travel up the lug k, and by bearing against the bracket t' carrying the latter up against the resistance of the spring lc. The bracket i' in itsr'ise lifts the frame D and swings it upward on its pivot, which, as before stated, is the shaft C. Turning of8o the crank k2 in the other direction causes it to travel downward .on the lug 7c and permit the frame D to swing downward on its pivot. The reciprocating ironing-board frame or support-E for the goods comprises a base-board 8 5 h, centrally upon which is mounted the ironing-board proper E. At the sides of the base h are flanged upwardly-extending plates h.

F is a hollow ironing or` polishing roller mounted near opposite ends in bearings g g 9o at theV tops of the sides t t', respectively, of the frame A. Outside the bearing g the ironing-roller carriesapinionf, which meshes with the cog-wheel o. Extending into the roller F is a gas-burner :n The drum C and roller m extend at the highest points of their circumferences in a plane about oneeighth of an inch above the guide-grooves n? Surrounding the` 7o which is connected by rods e with a sliding collar c2 on the shaft B. Mounted in a bearing t3 at the center of the lower forward crossbar t2 of the frame Ais a vertical rod e3, to the upper end of which is keyed a backward-eX-- tending arm c4. At its opposite end the arm e4 is connected pivotally to the collar e2. Ad-

,instable up and down on the rod e3 is acrossbar e5, formed at opposite ends with foot-rests e6. The cross-bar e5 may be secured in adjusted position by a set-screw e7, which thus operates, also, to fix the bar e5 against independent rotation upon the rod e3.

The shaft B is rotated from a suitable driving-power by belts, one of which is crossed,

- so that when they are shifted alternately to Y ward direction.

the fixed pulley lr they will rotate the latter in opposite directions.

In operation the ironing-board is slid forward out of engagement with the drum C and the article to be ironed placed thereon. The belt-shifting mechanism is turned by the operator with his feet to cause the drum C to rotate in a direction which will cause it to carry the ironing-board in the backward direction when the latter is pushed backward into engagement therewith. The frame D is adjusted upon its pivot by turning the crank 7a2 to cause the upper surface of the ironingboard to engage the ironing-roller F. The operator then pushes the ironing-board frame in a backward direction until it is engaged by theA drum C', which, owing to its frictional engagement with the under side 'of the baseboard 71., carries the ironing-board in the back- /Vhen the ironing board has passed under the roller F, the Operator Vby turning the cross-bar ewith his feet will shift the other belt to the fast pulley o" and f f cause the motion of the drum C to reverse and slide the ironing-board in the forward direction. The ironing-board may thus be reciprocated backward and forward until the article carried by it is suitably ironed. By simply turningthe crank 7a2 the pressure of the ironing-board against the ironing-roller may be regulated'at will. To prevent the lironing-board frame from being caused to travel too far in either direction, I fasten it at its forward end by means of a chain or other liexible medium CZ, of suitable length, to the upper forward cross-bar t2.

As the frame D is pivoted upon the shaft C, the drum C will always project the same distance above the lower sides of the grooves n3. Owing to the relative positions of the drum C and ironing-roller F, the adjustment of the frame D- on its fulcrum to regulate the pressure of the ironing-board against the roller F is under perfect control of the operator and may be quickly changed at will.

The operator may sit down, if h e desires, while operating the machine, and the crossbar e5 may be raised and lowered to suit his convenience.

I do not claim the belt-shifting Vmechanism in this application. A

Some articles have to be ironed under a great pressure to produce the best results, and, owing to the frame D being pivotedlon the' shaft C and the relative position of the ironing-roller, much greaterleverage comparatively may be had than were the frame D pivoted- -at the back of the machine, as is usual in machines of this class. In my improved machine, furthermore, the relative positions of the cog-wheel o and pinions q and f are never changed. In those ironing-machines wherein the shaft 'C is journaled in the swinging frame D the teeth of the cog-wheels have necessarily to be considerably longer than in 1 by Letters Patent, is-
