Specification of Letters latenti To all whom it may concern Be it known that I, ARTHUR HAMMER, a

Berlin, Germany, have invented new and useful Improvements in Ironing-l1a-chines, of which the following is a specification.

This invention relates to ironing machines of the type in which a smoothing iron Works in a rigid arm projecting from the machine frame, which iron works on the garment attached to an ironing table extending outward on all sides over the foot plate of the machine andcapable of a suitable displacement. i

The ob'ect of the present invention is to provide a single machine capable of com pletely ironing the whole shirt including the front. g

The invention consists in an improved ironing machine of the type referred to in whichthe ironing table during the ironing may be pressed against or held away from, as desired, the iron which reciprocates in a fixed planethereby enabling the front of the shirt to'be subjected to an ironing operation in one direction only.

One" example -of the J improved ironing machine according to the invention is illustrated'in the accompanying drawings in which- Figure 1 isa side elevation, Fig; 2 a front elevation, Fig. 3 a plan of an ironing table used in combination. with 'the'ironing machine for ironingthe shirt front, Fig. A: is a sectionalviw of a'detail of this ironing table, Figs. 5 aud o illustrate in plan and side elevation respectively and to a larger scale a device for stretching the neck-band, used in combination with the ironing table of Fig. 3. Fig. 7 represents a sleeve blank.

Sreprcsents a coil ironing board.

The machine consists substantially in a1 frame or standard a supporting laterally the driving mechanism, from which stand ard there projects at the front an arm 0 Carrying the smoothing iron b; the base of the standard supports the column a? for the ironing table e, along with the mechanism for the elevation-and drawing forward of thetable. The smoothing iron 5 to which steam for heating is supplied by means not 'shown in the drawing is mounted at the '-lower'end of the arm c'in suitable guides enabling it to move in a horizontal plane.

This movement is one of reciprocation and is eii'ected by means of acrauk disk [the .neath the smoothing iron.

zontal direction at right angles to-the mo tion of the smoothing iron by means of dovetail. guides. The up and down motion of the table is effected by means of a toggle k one end of which is pivoted to the bottom of the machine frame and the other to the sleeve guide of the table. crum of the toggle is connected through a link 1 with one end of a bell crank lever the other limb of which is formed as a pedal m for the operator of the machine. The joint connecting "the pedal lever to the link is provided with flutings in order to present a secure grip for the footof the operator.

The outward motion of the ironing table 6 is effected by means of a hand lever n" pivoted at a and provided with an upwardly directed arm 0 provided with a pin 0 which engages: in a vertical slot .guide 8 in the table, a counterweight being arranged ont-he said lever in such a manner that the table is hormallv held in' he smoothing iron has a semicircular recess on its right side correspondingto the necloband of the shirt. On the left side the ironing table overhangs its column for a considerable distance so that the smoothing iron in its middle position lies nearly over the center of the shirt front.

According as the back, sides, culls, neckband, or front of the shirt are to be ironed several boards are used as backing the sizes of which decrease regularly so that they can be laid one over another on the ironing table without. interfering with the work. Along with the cult ironing board 5 serving as Patented July 16, 1912.

Application filed June 1, 1911. Serial No. 630,562.

The middle fulposition underbacking when ironing the sleeves, a soi called sleevesblank a is'used,consisting of a thin board having the form ofa flat folded sleeve, over which sleeve blank the sleeve/is drawn to enable it to be ironed.

g The board or table for the ironingof the front of the shirt is illustrated in Figs. 3

and 4. It consists 01' a rectangular board or T preferably of a plate of aluminium. pros vigledwith the device illustratedin Figs. and 6 for stretching-the neck-band, this do vice. being arranged at the place denoted by the circle in Fig. 3. At the opposite end the board is provided with a roller 7 which serves the purpose of stretching out the shirt which is held fast at the neok-band and shoulders. For this purposethe lower end of the shirt is wrapped about the roller and-the latter is turned until the desired tension is attained. The roller is maintained in this tensioned position by means of a pawl seen at the left-hand corner of wedge segment attached to the upper plate 8 in such a manner that by moving the clamp arm to one side the plate .3, which is preferably provided at its front edge with downwardly pointing teeth, the plate is pressed upon the clasped shoulder of the shirt.

The device for stretching the neck-band consists of two semicircular wooden disks '0 and o. The two disk halves are mutually guided by means of pins to inihe disk 41 which slide in corresponding holes in the other half '0. In two lugs attached to-the half 4) is journaled a transverse spindle it provided with an arm y and carrying a lever a at each end, to which levers is jointed a metal strap 2 embracing theperiphery of the disk half 1;. On. the disk half 1/ is pivoted a cam disk 3 the edge of which is in contact with the straight edge of the part 1). On rotation of this cam disk the parts o and 'v are moved away from each other. This stretching device works in thefollowing manner. The neck-band previously ironed in spread out position is placed with the open side underneath the strap 2 and the latter pressed down by depressing the arm y by means of a clamp arm 4. The disk halves a and o are then caused to move away fromeach other by rotation of the cam disk 3 until the necessary tension is attained. The neck-band being thus stretched the shoulders are secured by means of the clamps q and the shirt tensioned over the board by tightening up the roller 0 in the manner already described. In this condition the board is placed on the ironing table which for this purpose is drawn forward fromnnder the smoothing iron by means of the lever 12,. ironing table has been pushed back underneath the smoothing iron the ironing may begin. This is efiected' by first elevating the table by leaning with the wei ht of the After the body on the pedal m and then starting the smoothing iron'by operating its coupling. On its motion to the right the semicircular recess in the iron encounters the stretching device for the neck-band and thereby pushes the ironing board to the outer end of its stroke, where it remains. During the actual" ironing a pressure will obviously beexerted on the ironing table by means of the pedal lever while the motion of the iron is to the left and on the reverse motion the pressure will be removed so that the .iron moves freely over the shirt'on the table. By this means the shirt front which can be firmly tensioned from the neck-band side, will. be subjected. only to pull during the actual ironing and'the formating of folds will thus be prevented.- Thealternate lifting and lowering of the ironing table which must be synchronous with the reciprocation of the iron produced by the driving crank disk, is easily effected by the operator who stands on the pedal plate m wit-l1 one foot on the joint connecting the pedal lever with the link Z and leans the weight of his body alternately on one foot or the other in time with the reciprocation of the iron, supporting himself by means of a'hand grip 5 on the front of the arm 0. The operator by these means has complete control of the up and down motion of the ironing table and also of the degree of pressure on the ironing table while at the same time he can easily follow the reciprocation of the iron. When the actual ironing is finished the ironing table preferably by pressure and with the machine at rest, is held for a certain time against the iron in order to completely dry the shirt. The remaining parts of the shirt are proceeded with in similar 95 manner using corresponding boards and blanks, but in this instance the ironing may take place at both strokes of the iron. It may be stated that by using the hereinbefore described stretching device for the neck-band, shirts with fixed collars may beeompletely ironed.

What I claim is:

1. In an ironing machine a vertically movable ironing table extending outward on all sides over the foot plate of the 1113:.
