CLOTH-PRESSING MACHINE- T0 on whom, it may concern."

Be it known that we, LAWRENCE SVOBODA and J AROSLAV KUDRLE, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Cloth-Pressing Machine, of which the following is a specification.

Our invention relates to an improvement in cloth-pressing machines of the class in which a sad-iron mounted on the machine to adapt it to be moved to any position on the cloth to be pressed is mechanically operated to be forced against the cloth or work laid for the purpose on a pressing board or buck to exert the required pressure.

In pressing cloth, particularly during the making of a garment, for properly pressing the seams, folds, and stitches it is necessary toforce the heated iron With great pressure against the work, andiin machines of the class referred to this is generally accomplished by means of levers'operating in conjunction with the iron and a treadle, whereby the operator may cause the iron to bear upon the work with the requisite amount of pressure. However, in the machines referred to the sad-iron has a flat ironing-surface, in the operation of which it is necessary that the pressure upon the iron be released to permit it to be moved to a different position on the work when the pressure is exerted anew, these operations continuing intermittently until the Work is completed, thus rendering the operation of such machines laborious and consuming much time in performing it.

Our primary object is to provide a clothpressing machine which will effect the pressing without requiring the sad-iron to be lifted from the work in changing the areasof pressure thereon, thereby to expedite the operation and reduce the amount of labor involved.

Another object is to provide a machine in which the area of contact at one time" between the sad-iron and the cloth to be pressed as compared to the area of the pressing-surface of the iron is relatively small, thereby permitting the iron to be forced with uniform pressure against the work with the advantage of producing more effective pressing with less labor than is required in the operation of machines as hitherto constructed with Specification of Letters Patent.

ing it to be rocked against the surface of the work under the constant pressure with which it is applied thereto, thereby rendering unnecessary the intermittent application of pressure referred to involving the release thereof for changing the position of the iron upon the Work.

Our invention is illustrated in the accompanying drawings, inwhich- Figure 1 is a view in front elevation, partly in section and partly broken, of our improved i machine; Fig. 2, a view of the same in side elevation; Fig. 3, a section taken through the sad-iron at the line 3 3 on Fig. 1 viewed in the direction of the arrows and showing parts in elevation; and Fig. 4 a section taken at the line 4 4 on Fig. 1 viewed in the direction of the arrows and showing the roller bearing for the reciprocable carriage.

A is the frame of the machine, formed of frame members A, supporting a top A, on which is immovably secured a pressing block or buck B. Secured to the under side of the top A as by bolts (2, are parallel depending guides 0, each having an elongated slot 0. Between the guides C is supported a carriage D, provided with an elongated longitudinal opening d, extending'transversely through it and longer than the openings 0, with which it registers. A roller E, mounted at its ends in the guide-openings c to roll therein, extends through the opening din the carriage to form a rolling-support therefor and permits the carriage to be freely reciprocated in the operation of the machine, as hereinafter described.

A lever F, fulcrumed at its lower end on the frame of the machine, is pivotally' con-'.

nected at its upper end at f with a bar D,

rigidly secured to the carriage, and between its ends at f to a horizontal lever G, which terminates in a bifurcated head g, having a cross-pin g secured in it.

H is a treadle journaled on a rod I at the back of the machine and resiliently held against depression by a spring K. The

treadle carries a board or plate H at rignt angles to it, and through a slot in theplate' a ver N is fulcrumed near its lower end at n to a rigid bar D projecting from one end of the A link M, pivotally secured to the carriage, and carries on its upper end a horizontally-extending bar P, provided with a head p, which is mounted on the vertical arm of the bell-crank N to turn thereon and is adapted to be vertically adjusted on the arm, being supported in any position by verticallyadjustable collars N. On the opposite end of the bar P a sad-iron Q is secured at its stem Q by a universal joint 1) and is provided with means for heating it and with an ironing-head q, formed with a rounded and preferably arc-shaped pressing-surface. The stem Q is surrounded by a sleeve q, of heatinsulating material, forming a handle by means of which to manipulate the iron.

Any suitable medium for heating the sadironsuch as gas, electricity, or other means-may be employed, though it need not necessarily be heated for all purposes of its use. \Ve have shown the iron as a hollow body adapted to beheated by gas by providing it with a chamber 1 having vent-apertures g in its sides to permit the products of combustion to escape, and into which chamber is projected a gas-burner R, pro' vided with tips 1, communicating with a pipe 1*, leading from a gas-supply. (Not shown.)

The operation of the machine is as follows: The work to be pressed is spread on the buck and the treadle is depressed. The depression of the treadle causes the lever G to swing at the pivotal connection f, drawing down wardly the link M, and thereby turning the lever N on its fulcrum n to force the sad-iron against the buck. The pressure on the iron having been once applied by continuance thereof the iron remains forced against the buck, while the operator, grasping the handle q, rocks the iron to and fro against the surfact of the cloth, the universal joint 1) permitting the iron to be thus rocked and to be turned at the joint to extend in all directions. It will be noted that at no time during the rocking or turning of the iron is it necessary that the pressure thereon be released. As the iron is rocked it causes the carriage D to reciprocate on its roller-bearing, swinging the lever F on its pivot and carrying with it in its movement the bell-crank lever N, which being pivoted at m to the link M, which in turn is pivoted at m to the lever G, causes the various levers and link to be shifted in the same direction to accommodate themselves to each other in their movements, thus renderingthe operation of rocking or turning the iron an easy one without affecting the continuity of pressure upon the iron during the shifting operation and without encumbering the operator with the Weight of the sad-iron.

We are aware that it is not broadly new with us to provide a sad-iron with a rounded base adapting it to be rocked thereon. Our cloth-pressing sad-iron, however, is provided as its distinguishing characteristic with a base describing an arc of a circle of aradius so short as to cause the iron to bear in any position it assumes in rocking it in either direction from its transverse center to the end of the are only at a relatively short section of the latter against the surface of the cloth under subjection to the pressure, thereby attaining substantial uniformity in the pressure exerted at any point in the rocking action.

What we claim as new, and desire to secure by Letters Patent, is I 1. In a cloth-pressing machine, the combination with a support for the work to be pressed, of a sad-iron having a rounded pressing-surface, a support on which the sad-iron is suspended to adapt it to be freely turned about a vertical axis and rocked radially relative to said axis against the surface of the work, a reciprocating carriage connected with the sad-iron support to be reciprocated by rocking the sad-iron, and means for pressing the iron against the work.

2. In a cloth-pressing machine, the combination of a frame on which to impose the work to be pressed, an upwardly and downwardly movable sad-iron support, a sad-iron having a rounded pressing-surface and suspended on its support to adapt it to be rocked, a roller-guided reci rocable carriage mounted on the frame an with which said support is connected to reciprocate it by rocking the sad-iron, and lever mechanism connected with said support for lowering and raising the sad-iron relative to the work.

3. In a cloth-pressing machine, the combination of a stationary support for the work to be pressed, a sad-iron having arounded pressing-surface, a reciprocating carriage, lever mechanism connected with said carriage to reciprocate it and by which said iron is suspended to adapt it to be freely turned about a vertical axis and rocked radially relative to said axis against the surface of said work, and means for actuating said lever mechanism to depress the iron against said support.
