RICHARD A. STRATTON, OF PHILADELPHIA, PENNSYLVANIA.

MANG-LE.

Specification of Letters Patent No. 16,887, dated March 24, 1857.

To all whom t may concern.

Be it known that I, RICHARD A. STRATTON, of the city of Philadelphia and State of Pennsylvania., have invented a. new and Improved Mangle; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists in arranging four rollers for mangling cloths in the following manner: Two of the rollers are placed with their centers in a line horizontally with each other, their surfaces being some distances apart, and are caused to turn in the same direction on ournals, `in suit-able frames, by gearing. Above and between these two iirst rollers, I introduce a third roller, around which the goods to be mangled are wound. This third roller is independent of the frames and has a rotary motion imparted to it by the contact of its surface, or rat-her that of the goods wound around it, with the two first rollers. Directly above this third roller is a fourth, which has its bearings on the end of vertical rods, connected to levers in such a manner that the said roller may be elevated at pleasure a considerable distance above the third roller, allowing the operator to remove and replace the latter at pleasure, t-he object of the whole arrangement being in order that the third roller, around which the clothes are wrapped, may become partially wedged between the surface of the two rst rollers by the superincumbent weight of the fourth roller and its appendages, thereby eiliciently mangling the clothes on the third roller, without winding and unwinding them, as in ordinary mangles, the above duty being performed by much less exertion for the operator, while the whole machine occupies much less space and is much less costly than the common mangles.

In order to enable others skilled in the art to make and use my invention I will now proceed to describe its construction and operation.

On reference to the drawing Figure 1 is a side elevation'of the machine. Fig. 2 is a detached sectional view of the rollers. Fig. 3 is a front View of the machine.

A A are the frames of the machine in which the axles ZJ of the rollers B and B have their bearings. To these axles, and on the outside of the frame, are secured the toothed wheels C and C', into both of which v gears the pinion Gr. The latter is allowed to turn loose on a pin it secured to the frame, and is furnished with a handle L, on turning which t-he rollers B and B are caused to turn in the same direction. The aXles CZ of the upper roller D are allowed to move freely in the slot at t-he upper portion of the frames A, and connected to the axles on each side of the roller D and inside the frames are the rods E, the lower ends of which are jointed to the pins z' on the bent levers F. The latter have their fulcrums on pins H secured to the inside of each frame, the other ends being connected together by the cross-bar f. The frames are connected together by the stays j j and e.

K is the middle roller around which the goods to be mangled are wound.

As themachine is shown in the accompanying drawing, the roller K with the surrounding goods to be mangled is introduced to its proper position in regard to the rollers, readyto be operated upon. It will be observed that the rollers B and B are a considerable distance apart, allo-wing the roller K to be partially wedged between their surfaces by the upper roller D, which is acted upon through the rods E by the levers F. The operator may place his foot or hang any additional weight on the crossbar f and proceed to set t-he rollers B and B in operation by turning the handle L. The action of the rollers (as I have found by experiments on a large scale) have now `a tendency by their peculiar arrangement not only to press the goods against the roller K but also wind them tight aro-und the same, effectually removing all the creases. By the peculiar posit-ion of the pin 2' in regard to the fulcrum H when the levers F are down the weight of the latter and the cross bar f must of themselves exert considerable force in pressing down the roller D. From this fact, together with the natural tendency of the roller Kto wedge itself bet-Ween the rollers B and B', it is evident that but little additional weight will be required on the ends of the levers F. The goods on the roller K being sufficiently mangled the levers F are raised by the operator to t-he position shown in red lines, which through the rods E raise the roller D until its axles d rests on the termination of the horizontal slots a in the frames A. The roller K with its goods may now be easily removed and replaced by I ain aware that rollers have been used for mangling clot-hes, but heretofore the goods have generally been Wound from one roller t-o another and pressed between their surfaces after the manner of ordinary calenders. Therefore I do not claim clothes, but

What I do claim and desire to secure by Letters Patent is- The rollers B and B in combination With the movable roller D, arranged and driven substantially in the manner set forth, for the purpose of'actingupon the roller K n such a manner that the cloth on the saine may be efficiently mangled Without Winding it from one roller to another, and for the purpose of removing and replacing the said roller K with facility.
