MANGLE.

' SPECIFICATION forming part of Letters Patent No. 594,430, dated November 30, 1897.

Application filed March 20,1896. Serial No. 584,186. (No model.) Patented in Germany July 10, 1895, No. 86,624; in France November 19, 1895, No. 251,818; in England November 29, 1895, No. 22,903; in Switzerland February 18, 1896,

To all whom/it may concern:

Be it known that I, FRIEDRICH ERDMANN RICHTER, model-maker, of 36 Merseburgerstrasse, Leipsic-Plagwitz, in the Kingdom of Saxony, German Empire, have invented new and useful Improvements in Mangles, (for which I have obtained a patent in Germany, No. 86,624, hearing date July 10, 1895; in France, No. 251,818, bearing date November 19, 1895; in Great Britain, No. 22,903,'bearing date November 29, 1895; in Switzerland, No. 12,004, bearing date February 18, 1896, 1,297, bearing date specification.

My invention relates to a mangling-machine by means of which two parties may mangle independently of each other, the machine being used in common and driven either by hand or by machine power.

In the accompanying drawings a manglingmachine is represented.

Figure 1 is a front view of the same, the left-hand side showing the mangle in operation, while on the right-hand side the lowest set of rollers is represented out of action and the upper set has been omitted. Fig. 2 is a side view of the same.

The improved mangling-machine comprises, essentially, two standards, consisting each of two plates or a and serving for the reception of the drum 1). Upon the shaft'c of the drum 1) a toothed wheel (1 is rigidly secured, which is rotated together with the drum by means of toothed wheels (1 d 0Z pivotally arranged between the plates or a of one of the standards. The toothed wheel (1 is mounted upon the shafte of the fly-wheel e, and the toothed wheels 01 and d are fixed upon an intermediate shaft. The toothed wheel 01 meshes with the toothed wheel (1, and the toothed wheel (1 meshes with the toothed wheel (1 The operation takes place either by means of a handle 6 directly fixed onthe fly-wheel e, or by means of a pulley especially arranged.

On each of the two sides of the drum 1) are arranged two pairs of rollers f f and g g, one of which is placed above the other and which can be used at the same time, the arrangement being, moreover, such that each single pair of rollers can be disengaged and that one pair, two pairs, three pairs, 850., may be used for the working, according to requirements. The rollers f and g serve for the reception of the washing to be mangled, which has to be laid with hand over the entire length of the same. The rollers themselves are supported in the arms h in such a manner as to, be removed easily out of their bearings. For this purpose the arms it have at the upper ends slots which open to the upper side and serve for bearings of the rollers. The arms h are adapted to turn about bolts 2, fixed to the plates at, so that an engagement and disengagement of the rollers mounted in these arms with the drum can be executed. In order toprevent the arms with the rollers moving too far in disengagement, stop-bolts k are arranged which retain the arms after disengagement in their inoperative position. The pressing-rollers f and g are mounted on arms m, pivotally arranged upon bolts Z, and serve to press the rollers f and 9 against the drum b in order to efiect in this way the smoothing of the washing. When disengaged, the arms m rest against the stop-bolts it, so that a further'outward movement of the pressing-roller is prevented.

In order to press the pressing-roll ers f and "g against the rollers f and g and the latter against the drum 1), there are arranged rollers 01., which are pressed against the pressingrollers f and g"by means of double lever-arms 0, to the longer shank of which a Weight 19 is attached. By adjusting the weight 19 on the lever-arm the pressure required for smoothing the washing can be suitably regulated. Each ofthe rollers 02 is mounted in a rod q, swinging round the point 'r and connected at its shorter shank by means of a link-piece s with the disengaging lever t. The double lever-arm 0, which is adapted to swing round the point 0, catches with its shorter shank suitably bent behind the suspending arm of the mangle-rod q, and presses thereby the roller n against the pressing-roller f. or g, from which the pressure is transferred to the rollerf or g and to thedrum b. The disen arms 7t.

lowerside of the longer shank of the lever 0, carrying the weight 1). From this arrangement results that when the lever t is brought into the position shown in Fig. 1 on the righthand side the lever 0 raises with the weight, whereby the shorter arm of the lever 0 sets free the man gle-rod q with the roller attached to it. Because the mangle-rod q is connected with the longer shank of the disengaging lever thy means of the link-piece s, the manglerod q is turned round the point r and the roller 01 releases the pressing-roller.

Vhen one pair of rollers is disengaged, the roller for g is removed and wound abo at with the washing to be smoothed, after which the roller is put backinto the bearings of the Now the roller wound about with washing is pressed against the drum 1) by means of lifting the pressing-roller, after which the levers 2, being arranged on both sides, are lifted, and effect thereby a pressing of the rollers it against the pressing-roller. The drum 1) is constantly rotating, and because the pressing-roller is pressin the roller wound about with washing against the drum, the roller wound about in consequence of friction is also rotated and elfects thereby the smoothing of the washing. After sufficient mangling the roller wound about is released by means of the disengaging levers t and may be wound about again after the smoothed washing has been taken off. The

drum Z) remains constantly in movement because one pair of rollers can be provided always with washing to be smoothed.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

In a mangling-machine the combination of a rotary drum supported between two standards, with two rollers for the reception of the washing to be smoothed, arranged on each side of the said drum and supported by pivotal levers, rollers also arranged on each side of the drum and supported by pivotal levers and pressing upon the rollers carrying the washing, rolls also arranged on each side of the drum and supported by pivotal levers and pressing upon the said pressing-rollers, weighted levers the shorter arm of which presses against the longer arm of the levers carrying the said rolls, and levers the longer arm of which forms a handle and the shorter acts upon the longer arm of the said weighted levers and being connected by means of link-pieces with the shorter arm of the levers carrying the said rolls; as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
