To aZZ- whom it may concern:

Be it known that l, HERMANN SCHMIDT, of the city of Berlin, in the Kingdom of Prussia, German Empire, have invented Improvements in Ironing-Machines, of which the following is a specification.

The object of the invention is to provide a simple and eifective machine by means of which a number of linen collars7 cuffs, or similar goods can be ironed at the same time mechanically, saving thereby much time and labor, and furnishing a better and more uniform prodncnthan was before possible by hand or the ironing-machines in use.

My invention embraces, also, a device which takes held of the linen to be ironed, but allows a very rapid application and removal of it; also, a device by which the operator can alter fthe pressure of the hot ironing roll or rolls according to his will and to circumstances.

ln the accompanying drawings, which form part of this specification, similar letters of reference indicate corresponding parts.

Figure l is a sectional. side view of the ma hine. Fig. 2 is a vertical cross-section of saine. Fig. 3isa plan view. Fig. lisavertical longitudinal section of the carriage used on the machine. Fig. is a front view of the table and the carriage hand-wheel removed. Fig. 6 is a side elevation, partly in section, of an attachment 'to the machine, showing the parts of the machine proper in longitudinal section. Fig. 7 is a partial plan view of the same part. Figs. to 7 are drawn-double size of the otherV figures.

The table o receives a reciprocating motion upon the bed o, fixed to the frame b ofthe inachine, by the connecting-rod d and the oscillating slotted lever c, which is moved by the crank f. The crank f is set in motion by means of the wheel It, keyed to the crank-shaft, and the gear g, turning with the main shaft, which receives its rotary motion through beltconnection from any suitably-situated pulley. As the gear g revolves with uniform speed, it is easily understood that the movement of the table o to the left is faster than that to the right at the back-stroke'. The carriage z', supporting the linen k by plates j, which are shoved into recesses on the sides of the carringe-frame, rests upon the table a., to which it can be fastened.

The hollow ironing-roll p is heated by gas, steam, or other suitable means, and rotated from the gear f/ `through the wheel l. The speed of the roll' p should be always greater than that of the carriage i. The roll p turns in bearings of the Aforked lever in., which swings round the shaft y] of the gear g, and is counterbalanced by a weight in such way as to have the tendency to be lifted from the plates j. llhis roll'p can be pressed down to the plates j by the operator, either by hand or by stepping with more or less force upon the foot-lever o, connected through two rods to the two branch( s of the lever m. The linen It (in the drawings are shown collars) is inserted, one piece after the other, between the plates j, and fixed in its desired position the other, and screwing them all together and against the back part of the carriage-frame by means of the screw 'r andthe hand-nut s. For this purpose the screw r is attached with one end to the back part of the carriage-frame, the other end of the screw o resting in the lower part of the slit of the guide-cam 1, which reclines backward as much as to allow the plates j to be shifted about one-half an inch forward lfor inserting the linen properly between them. The front end of the screw s is then lifted up in the slit of t, so that the nut s can bear fairly against the iirst plate j, when by some turns of the nut s all the plates j are screwed together and the linen rmly clamped. The front edge of each plate j is beveled under an angle of about thirty degrees, while the back edge is square, for producing a better clamping-grip. After the linen is fiattened upon the plates j the machine is started, the roll p gently drawn down to give a light touch to the linen, and then a greater pressure applied to the roll p by bearing heavy on the lever o until the required gloss is acquired. When the work is finished, the carriage ,with the linen on it, is removed from the table a and rolled, by means of a wagon running on a cross-track, (not shown in the drawings) to a place where the plates j are unscrewed, the lin en taken off, replaced by new ones, and properly adjusted. The carriage i is now ready to by pushing one plate j against IOO undergo again the described treatment. During the time of discharging and recharging the carriage another one already charged is treated in the machine. Notwithstanding the Work of ironing goes on in this Way very rapidly, still more time may be saved by using two ironing-rolls, p and p, instead of one, Figs: 6 and 7. The second roll, p', heated as above described, is jonrnaled in the branches of the elongated lever m; but the journal-boxes a are not rigid, but are movably fitted to their housings and kept down by springs q. The roll p must be arranged in such a Way that when the lever m is brought down the roll p touches the linen prior to the roll p, and with a lighter or heavier pressure, as the springs behind the journal-boxes are less or more compressed. Zhen the play of the boxes is exhausted,then the first roll, p, comes in contact with the linen, and both rolls p and p are then acting upon the linen With a pressure depending from the Weight which is brought to bear upon the foot-lever o. For two rolls, p and p', the coun- `ter-Weight ofthe lever m must be heavy enough to give to the front end of it the tendency to rise. The roll p revolves in the salne direction as the roll p, for which purpose it is geared to the Wheel l of the roll p by the aid of an idler, w, `which construction is clearly shown in Fig. 6.

It must be understood that the shape of the plates j depends upon that of the goods to be ironed, as also the degree of the pressure of the roll or rolls p p. By the arrangement above explained the operator has this pressure entirely under control, and may alter it at any moment.

In some cases it is desirable to iron the linen in different directions. To accomplish this seams a turn-table, x, turning round the trunnion o, is mounted to the carriage z', which .supports the plates j in the manner described above. This turn-table v can be arrested in any position, or it canbe turned during the ironing process, so as to present the linen to the roll or rolls in any desired direction.

The speed of the roll p and rolls p p depends upon the kind of goods to be ironed. In all cases it must be greater than that of the carriage 1T, as above mentioned. Vhen two rolls are employed they may have the same speed, or, if preferred, one may revolve faster than the other. These arrangements depend Wholly upon the judgment of the manufacturer, and are not claimed.

I claiml. The table a., combined with the carriage t', and means, substantially as described, for reciprocating the said table and carriage, clamping-plates j, ironing-rollspp, and mechanism, substantially as described, for moving said parts t', y', and p, in the manner specied.

2. The .plates j, made With beveled edges and combined With the table a, carriage i, rod d, hand-nut s, and cam t, substantially as specilied.

3. In an ironing-machine, the rolls p p', journal-boxes a, lever m, and springs q, substantially as shown and described, in combinatio with table a, and carriage t', as and for the purpose set forth.

This specication signed by me this 27th day of February, 1883.

HERMANN SCHMIDT.
