SECIFICATION forming part of Letters Patent No. 506,428, dated October 10, 1893. Application led May 16, 1892. Serial No. 433,101. (No model.)

To @ZZ whom it may concern:

Be it known that l, HORACE L. GEE, a citizen ofthe United States, residing at Troy, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Ironing-Machines, of which the following is a specification.

My invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts inthe several Iigures therein. y

Figure l of the drawings is an end view in elevation of my improved ironing-machine.' Fig. 2 is a vertical longitudinal section of the same, taken on the broken line, 22, in Fig. l, with the lower part broken away. Fig; 3 is a vertical cross-section taken on the broken line, 3-3, in Fig. 2, extended through the parts broken away in the latter figure.

A, A-f represent the end uprights of the main fr'ame of the machine which support in suitable bearings a rotary polishing-roll,.A2, and upper and'lower feed-rolls, A3, and A4-. The middle or polishing roll is adapted to be heated in the usual manner by the combustion of gas conveyed interiorlyfof the hollow roll by a pipe, A5-, inserted through oneof the roll-journals apertured to receive it, as shown in Fig. 2. The pipe is non-rotaryand is Supported in a cap or bracket as indicated l :...Fig. 2. Combustion takes place at the out-Lv c, "fr small apertures, A6, in the gassupply` The rolls, A3, and A4-, are preferably cethed in the usual manner and serve to feed nzpress the fabric to be ironed against the polishing-roll. The feed-roll shafts are rotaryin bearing-boxes, A7, movable in slideways, As-,in the frame uprights. The pressure of the feed-rolls upon the polishing-roll is maintained by weights, W, and W. The weight, W-, is adjustably secured to one arm of lever, W2,` fulcrumed upon the rod W3-, the ends of which are supported by the end uprights of the frame. The other arm of this weight lever is con- The other end of the latter lever is connected by link, W6, with the arm, W7, fixed upon the rock-shaft, WS. Another arm, Wi-, fixed upon the rock-shaft, is connected by link, W10-, with the arm, W12-3 of the lever which is pivoted upon the shaft of the upper feed-roll.. The other arm, W14- of such lever is connected by link, W15-, with the lever, Wlfulcrumed atene end upon the rod, W17-, and provided at the otherend with the adjustable weight, W. A like system of weights and levers, not Wholly shown, is provided at the other end of the rolls.

By means of a hand-lever, A9, fixed upon one end of the rock-shaft, W8, the shaft can be rocked to force the feed-rolls awayfrom the polishing-roll and back again to the position shown in the drawings, the rock-lever being held in any desired position by the ratchet, A1-, and pawl, A12-. When the rolls are/forced apart, the weights rest upon the floor, W19, or other suitable support.

Most ironing machines having a heated polishing roll are provided with mechanism for separating the rolls to admit of repair or renewal of the material with which the feedrolls are clothedor for other purposes. Itis necessary to rotate the polishing-roll to heat it equally on all sides before work is commenced, and to prevent delay the rotation of such roll should be continuous to keep it uniformly heated, while the feed-rolls are temporarily forced away from it for repairs or other purposes. The clothing of the feedrolls can frequently be better repaired while in motion than they could be while at rest, and one of the objects of my invention is'to provide a 'combination of a polishing roll supported infixed relation to the machine frame, with feed rolls and feed roll raising and lowering mechanism adapted to raise and lower both feed rolls and at all times to support said rolls with mechanism for maintaining the rotary movements of all the rolls in whatever position they may be made to assume by the system of weights and levers.

Another object of my invention is to pro- IOO vide a convenient means for communicating to the feed-rolls a much slower rate of rotary movement than that communicated to the polishing-roll. Heretoforesuchvariationsinrates of speed have been accomplished in a limited degree by means of an expensive system of intermediate cogged wheels and pinions. As heretofore constructed, the practical limit of variation has been about twenty-two revolutions of the polishing-roll to one of the feedrolls. It is desirable to increase this ratio two or three fold; and I have ascertained that by use of worm-gear connections between the polishing and feed-rolls, I can easily and cheaply obtain any desired ratio of rotary speed, and a steady, even movement of the feed-rolls. Such a construction also permits of a considerable movement of each of the feed-rolls away from the polishing-roll without interfering with the continuous movement of all the rolls. When desired power may be applied directly to the polishing-roll, but I have shown a separate shaft, B, having end-bearings in the frame uprights, provided at one end with a loose and fixed driving-pulley,

B-, and with a gear-wheel, 132-, at the other end, adapted to engage with gear-wheel, B3, fixed upon the trunnion of the polishing-roll to rotate the same. The drive-shaft, B, is also provided witha beveled gear wheel, B1-, fixed thereon and adapted to engage with each of the gear-wheels, C and C-, fixed respectively upon the worm-shafts, C2, and C3-. The worm-shafts are rotary in bearings contained ""iwangle-brackets, C4-, secured to the frame uprights by screw-bolts, C5. The worms, D-, are adapted to respectively engage with the worm-wheels, D2, D3-, severally fixed upon the feed-roll shafts.

It is obvious that the driving-shaft will rotate as many times during each rotation of the feed-rolls asthere are teeth in the wormwheels. The larger the diameter, the greater the number of teeth which can be practically employed in the worm-wheels, the greater the leverage obtainable to rotate the feed-rolls. By having considerable leverage I amable to impart a steady even movement to all the rolls instead of an unsteady, jerky movement to one or more of them.

The gear-wheels, B2-, and B3-, may be-of the same size or one may be larger than the otherV and both made detachable and interchangeable to produce a varying ratio of speed between the feed and polishing rolls, when desired.

' I'can easily make fifty to seventy-five teeth on a twelve o`r"rteen inch Worm-Wheel, producing a relative rate of speed between the polishing roll and feed-rolls of fifty or seventy-ve to one.

By having the worm-shafts parallel with the respective slideways, A8, and the worms of the proper length, the worm-Wheels will not be disengaged from the actuating worms by the movement of the feed-rolls to and from the polishing-roll, since the worm-wheels will travel longitudinally of their respective worms while in mesh therewith.

What I claim as new, and desire to secure by Letters Patent, is-

l. In an ironing machine, the combination of the polishing roll, the feed rolls, a worm gear intermediate the polishing roll and each feed roll, mechanism at each end of the machine for moving` the feed rolls to and from the polishing roll said roll moving mechanism being adapted to support the feed rolls in every position of the same, and consisting of two pairs of` approximately parallel links,the links W4 and W6 forming one pair, and links W10 and W15 forming the other pair,.each pair connected loosely by a lever pivoted on the axis of a feed, roll, the links W6 and W10 at one side of the rolls being connectedby mech-` anism adapted to move them oppositely, and the links Wl1 and W15 at the other side of the with a counter-balancing weight, substantially as set forth.

2. The combination of the polishing roll;

supported in` fixed relation to the machine frame, a spur gear fast on the shaft of said" roll, feed rolls having eachva worm wheel; on its shaft, the worm shafts, a bevel gear on each of said shafts, mechanism for continuously and positively driving thepolishinglrolll andthe feed rolls by the medium of intermediate gears B? and B1 and; feed roll raising and lowering devices adapted to raise and` lower each feedroll and to support said rolls in every position of the same; substantially as set forth.

3. In an ironing machine, the combination of a feed roll having a worm. gear, aworm shaft supported to turn in fixed bearingsand provided with a bevel gear, a polishing roll having a shaft provided with a spur gear,;a driving shaft having alike gearmcshingiwith the polishing-roll shaft gear and also having a bevel gear meshing with the bevel gear of the worm shaft, and means for moving the feed roll to and from the polishing roll in a right line without disconnecting any of the gears, substantially as set forth.

In testimony whereof I have hereunmtoset my hand thisllth day of` May, 1892-1 HORACE L. GEE;
