^ Letters Patent N 96,646, Vdated November 9,`1869.-

I IMPI-oven MANCLE.

The Schedule referred to in these Letters Patent and making part of the same.

ments of devices forfworking a table reciprocatingly. under a pressing and smoothing-roller, on which tablev the clothes to be mangled are spread, the pressing and mangling-roller ,being provided with adjustable' Weights, for varying the pressure.

Figure l represents a side elevation of my improved Figure 2 represents sectioned.

Similar letters of reference indicate corresponding parts.

A A are two side frames, preferably made 'of castmetal, and connected together by rods B. 0 C are two rollers, mounted `in bearings at each end, in the said side frames.

They support the reciprocating table D, having'two straight-toothed racks E on its lower side.

F is the upper mangling-roller. e

It is provided with Abearings G, arranged to move up and down in slots in the housings, -and they are connected to levers H, jointed to the frame at I, and connected, byrods K, to other levers L, pivotedto the frame at M, and provided witll'weights N, for varying the pressure of the roller on the clothes, the said weights beingadjustable along the said levers.

The table and roller are, in practice, covered with cloth, and the cloth cover for the table is connected toA one end by a clamp, and at the other by stroller, having a ratchet and holding-pawl', for stretching the cloth over the table.

vThe rods K are made in two parts, and are connected by a screw-threaded sleeve, K', in which the an end view, with some parts rods may be adjusted for shortening or lengthening l them. In practice, I propose to provide them with right and left-hand threads, so as to effect the adjustments by turning the sleeves.

O is a driving-shaft, carrying toot-hed wheels P,

gearing with the racks E, for moving the table back and forth.

For simple and cheap machines, lthis shaft may' have a hand-crank for turning it backend forth; but

for the-best class oi' machines, to beoperated byhand, or other power, constantly moving in one direction, I provide a curved rack, Q, on thet'aceot' a disk, It, conneetedto the said shaft, which rackis toothed on both the nuterand innci; faces, and over the ends, with which-.I gear a driving-pinion, S, mounted on a shaft, T, fixed in a bearing, U, capable of sliding np and down in va slotted plate, V, supported in bolts W, projecting from the main frame.

. Between the ends of the curved rack, a guide-plate, -X, is attached to th'edisk, having two curved guiding` faces, Y Z, which come against the inner endof the shaft T, at each time one end of the said toothed rack arrives at the pinion, by which' the pinion is carried either up o r down, as the lcase may be, around the end of the said rack, to reverse the motion thereot', and thereby that ofthe table.

` The table is provided with guide-pulleys a, suitably arranged in the frame, to work against the edges ot' the table, for controlling its position laterally.

Having thus described my invention,

I I lclaim as new, andv desire to secure -by Letters 'Patent- 1. The combination of the table D, rollers C, driving-shaft 0, wheels P, racks 1*]pressing and man gling-mller F, sliding bearingG, levers H L, connecting-mds ]I, and weightsv N, when all'arranged substantiallyas specified.

2. The combination, with the driving-shafts O and .'l, of the diskR, toothed rack Q, guide X, pinion S,

and sliding bearing U, all substantiallyv as specified."

The combination, with the frame A, and the subjectmatter: ofthe second claim, of the-slotted plate Y, supported onv the bolts W, substantially as specified.
