Y., ASSIGN- ORS TO SAID HEINS, AND JOHN H. LEE, OF NORWALK, CONNECTICUT. IRONING-MACHINE. SPECIFICATION forming part of Letters Patent No. 340,225, dated April 20, 1886. Application filed October 31, 1884. Serial No. 146,892. (No model.) To all whom it may concern: Be it known that we, CHARLES A. LIEB and CHARLES L. HEINS, of the city and State f- New York, haveinvented an Improvement in Ironing-Machines, of which the following is a specification. This invention is animprovement upon that set forth in our application No. 142,191, filed September 4, 1884; and it relates to the peculiar construction of the ironing-cylinder and to the device for applying pressure to the iron and holding the saine while the work is being done. In the drawings, Figure 1 is a vertical section longitudinally of the cylinders and through part of the standard. Fig. 2 is a crosssection of the ironing-cylinder. Fig. 3 is a side view of the lever for moving and clamping the shaft supporting the revolving iron. Fig. 4 is a section at the line as x. Fig. 5 is an end view of a portion of one head of the lower roller, and Fig. 6 is an elevation of the lever shown in Fig. 3. The base c, standard b, and bearings c d for the shaft e are similar to those in our aforesaid application, so, also, is the tubular box h, at the top of the standard b,and the shaft i, which passes through said standard and is bent outside the bearing, and the part 2-receives the ironing-rollerl with the tubular hub 5, to revolve freely upon such shaft. The shaft e is provided with the handle e', by which it and the cylinder f are revolved. This cylinder f is supported by the two heads f f2, the edges of which are beveled or conical, and they receive between them the sheetmet-al sleeves of the cylinder. These sleeves f3 f* are each of sheet metahof suitable thick- -ness, and the inner cylinder is of a size to fit closely within the outer cylinder. These sheet-metal sleeves f8 f4 are to be contracted, so as to be of a smaller diameter, by lapping the edges of the respective cylinders, and one cylinder is within the other, then the said cylinders are introduced into the seamless tube forniing the woven or knitted surface upon which the material to be ironed is laid. The conical heads are applied to the ends of the cylinders and the sheet metal ex-y panded by forcing the conical heads toward each other until thelapped portions pass clear of each other and the abutting edges of the sheet metal come together, the longitudinal separation of the outer cylinder being at the opposite side to the longitudinal separation of the inner cylinder, so that the cylinders inntnally support each other and the elastic or woven surface upon the same. The headf2 is held from moving endwise upon the shaft e by thev collar e2, and there is a screw-thread upon the shaft e, near the end within the hub of the head f', and the heads may be revolved, or the shaft is turned while the heads are held stationary, and one head is thereby screwed toward the other head, and the conical surfaces of the heads expand the sheet-metal cylinders and stretch the woven bag, forming the surface of the cylinder, as aforesaid. The hub k of the headf is split longitudinally, and it is-provided with projecting ears m, for the clamp-screw n to pass through, so that by tightening such screw after the cylinders have been expanded the hub will be made to clamp the screw portion of the shaft and connect the cylinder and its shaft firmly. The ironing-cylinderlis heated by a gas' flame or otherwise, and it is free to be revolved upon its shaft by contact with the material that is being ironed upon the bed-cylinderf. The shaftiis bent or crank-shaped, the portion 2 being eccentric to the part that passes through the portion h ofthe standard. There is upon the shaft i, adjacent to the standard b, a split shell, s, the edge of which surrounds a cylindrical flange, b', upon the tubular upper part, h, of the standard b, and the hub s of this shell is clamped rigidly to the shaft i. There is a lever, t, having an opening in it, so that the lever passes at each side of the hub s', and thepivot pin t2 passes through the two parts of the lever and through the hub, but at one side of the shaft. The .long end of this lever is made as a handle, t3, and the short end is :made with a box or fork, tf, the inner faces ofwhich are slightly tapering, and upon the edges of the shells there are lugs s4, projecting one at each edge of the split or saw-cut in such shell s, so that by swinging the lever upon its fulcruniv the fork t* presses against the outer surfaces of IOO the lugs Is and springs the split shell sufficiently to-cause it to clamp the cylindrical flange b and hold the parts so that the shaft i cannot turn. The object of this construction is to allow the attendant to grasp the handle 1,3 andpartially rotate the hub s', shell s, and shaft i and by the crank oreccentric portion of the shaft 'i apply the necessary pressure of the ironing-cylinder to the goods upon the bedcylinder, and then by a lateral movement or swing of the lever upon its pivot to canse the fork t to close the split shell. grasp the sta tionary cylindrical flange, and hold the parts firmly in position while the bed cylinder is being revolved and the ironing performed. The revelse movement releases the parts, and it is preferable toemploy a coiled spring, v, within the cylindrical flange b', with one end passing into a hole in the standard b and the other end into a hole in the hub s, so that the expansion of the spring will partially turn the shaft and lift the ironing-cylinder off its Work. We do not herein claim the devices set forth K in our aforesaid application No. 142,191,1iled September 4, 18M-viz., the hollow cranked shaft supporting the ironing-cylinder and a lever for partially turning the shaft, a spring inders, one within the other and split lengthwise, and the fibrous covering for the bcdcylinder, the latter being expanded by the sheet metal cylinders, and the conical heads acting upon the saine, substantially as set forth. 2. The combination, with the ironing-roller and its crank-shaped shaft, of a standard having a tubular box, h, at its upperend supporting the shaft, a cylindrical iange,v b', upon the boX h, a split shell with projections upon it, ahub by which the shell is attached to the shaft, and alever pivoted upon the hub for moving the shaft. and a fork, t, of the level` for tightening the split shell upon the cylindrical flange, substantially as set forth. Signed by us this 29th day of October, A. D. 1884. CHARLES A. LIEB. CHAS. L. HEINS. Witnesses: GEO. T. PINCKNEY, WILLIAM G. Morir.
