T mar-aria of Letters Patent No. 20,002, dated April 20, 1858.

.To aZ l whom it may concern: I

Becit known that I, SAM. NoWLAN, of the city, county, and State of New York, have invented certain new and useful Improvements in Mangles, of which the following is a full, clear, and exact' description, referv ence' being had to the accompanying drawing, which forms part of this speclficatlon,

and in which-.-

Figure 1 represents a vertical section through a piece of furniture commonly called dressing-bureau, and Fig. 2 a cross section through the line w y of the mangle.

My invention consists in the peculiar construction and arrangement of the mechanism of a mangle, whereby the apparatus without losing its eificiency is reduced to such compactness as to enable it to be combined with any suitable article of furniture,

which will serve the two purposes of a man-. gle and of a furniture adapted to such other uses as made for. I

To enable others to make and use my invention I proceed now 'to describe its construction and operation.

The general construction of the bureau presents no particular feature of novelty with the exception of the following: The first or upper drawer does not extend throughout the whole depth of the bureau. The backboard A is secured at right to the sides and the bottom of the drawer so as to occupy about the middle of the let down,

depth of the bureau when the drawer is shut, thus leaving a space behind it where the mangle is located. The cover or top plate of the bureau is made of 2 halves which are hinged together so as to fold and allow the rear half to lapover the front one as shown in the annexed drawing. On lifting the rear plate or on folding it over the hinges, the mangle is uncovered and ready to be operated upon. Another peculiarity of the construction of the bureau consists in the addition of an adjustable table T hinged to the backboard of the bureau at m. This table when not in use is when it lies flat against the backboard, so that the bureau may be placed against the wall of the room. But when the mangle is used the table is lifted up to the horizontal position shown in Fig. 1, in-

angles the bureau.

The mechanism of the mangle consists in two rollers Rand R the journals of which These are placed in a frame F which is permanently secured 'to the inner sides of the bureau. I would recommend that the bushes D or those of'the lower roller be permanently fixed intothe bottom of the frame F for the. purpose of securing the proper relation of the gearing parts and to render them less liable of getting out of working order.

To one of the journals of the lower rollers and between the end of said roller and the bushes is a cog wheel n which meshes into and is operated by a pinion P supported by a bracket cast onto the side of the frame F. This pinion has a shaft the end of which projects out of and through the side of the bureau and is provided there, with a set of levers L or a crank-or flywheel as the case may be.

The bushes incasing the journals of the upper roller are loose in the frame and are therefore liable of an u and down sliding motion within the gui es or sides of the frame. To give the requisite pressure of one roller onto the other, I use a powerful spring F which is. inserted between the top of the bushes D and the plate G, which is adjustable by means of screws or bolts for the purpose of increasing or diminishing the intensity of pressure of one roller onto the other. The roller R is provided with an apron L one end of which is fixed in a slot of the cylinder B. Other equivalent means of securing the end of the apron to the cylinder may be used.

The mangle is so arranged in relation to the other parts of the apparatus, that the surface of, the table T should be in a plane tangent to the cylinder R and that the axes of the 2 rollers R and R shall not be in a perpendicular plane, but that they shall occupy an inclined position in relation to each other.

The operation is as follows: When the bureau is to be used as a mangle, the'table T is lifted so as to occupy a horizontal position. The strut S is then taken out of the groove and placed upright beneath the table to support it. The crank is then put side grooves 9 thus completing the back of are. set in suitable metal bushes D and D. 1

in motion in the direction of the arrow 0, whereby the apron is unwound. The cloth to be mangled is then slightly wetter, folded.

and laid on the apron and this done the crank motion is reversed 21. 6. turned in the direction of the arrow to. By this operation the apron is wound up together with the cloth. After the cloth has been rolled.

and pressed sufficiently, the crank motion is again reversed and the apron rolls out with the cloth completely mangled which latter is then removed.

I do not confine myself to the application of mangles constructed and arranged as above described, to bureaus only, as sub stantially the same principle of construction 1 can be applied to any land of furniture such aswardrobes, tables, desks, etc.

Having now fully described my 1mprovement what I claim as my invention and desire to secure by Letters Patent is The mechanism of a mangle constructed and arranged in relation to and in combination with parts of any suitable articles of furniture in the manner and for the purposes specified.
