. SPECIFICATION forming part of Letters Patent No. 660,301, dated October 23, 1900.

Application filed June 1, 1899- To all whom it may concern.-

Be it known that 1, Lens J. LINDBEoK,a citizen of the United States, residing at Bishop Hill, in the county of Henry, State of Illinois, have invented certain new and useful Improvements in Mangles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to mangles, and has for one object to provide a device of this na-, ture which will be simple and cheap of. construction, easy and efflcient in its operation, and which, moreover, when not in use will have an ornamental appearance.

A further object of my invention is to provide a readily-operated tension device for the rolls of the mangle and means for operating the rolls. i

In the drawings forming a portion of this specification, and in which like letters of reference indicate similar parts in the several views, Figure 1 is a front view of my mangle when closed and showing the ornamental appearance thereof. Fig. 2 is a front view of my mangle with the front open and readyfor operation. Fig. 3 is a section on line 3 3 of Fig. 2. Fig. 4 is a section on line 4 4 of Fig. 2. Fig. 5 is a detail section taken through the shaft M and showing its cam and its yieldable connection therewith.

Referring now to the drawings, in operating in accordance with my invention I form a casing comprising a back a, sides I) and 0, top d, and bottom 6, the front comprising an upper hinged lid f, hinged to a horizontal partition g in the casing and adapted to inclose a mangle-compartment, there being a lower portion below said partition having drawers h for any desired purpose.

It will be noted that the sides I) and c at their upper portions, which are engaged by the lid f, are sloped backwardly from the bottom of the lid to the top of the casing, giving the casing when closed moreof the appearance of a desk.

Serial No. 719,029. (No modal.)

and a rearflange hisformed at the rear edgeof the plate, said front and rear flanges projecting in-the same direction with the upper and lower flanges. The guide-plate c is similar to the guide-plate b and is separated from the side cof the casing by an interspace t, as

shown.

Journaled in bearings formed in theplates bandc are the trunnions k and lof a roller m, which roller, has a sheet of fabric a secured thereto by means of tacks or other form of fastening means along one edge of, the sheet. This sheet is substantially thewidth of the roll and the secured edge thereof lie longitudinally of the roller.

The trunnionlof the rollerm passes thlgough the plate 0 and into the inter-space t, within which interspace and upon said trunnion is arranged a pinion 0,-meshing with a second and larger pinion-p upon a shaft r, journaled in the side of the casing and having at its outer end a crank t, through the medium of which its shaft may be rotated to rotate the roller m.

Slidably arranged between the upper and lower flanges of each plate I) and c is abearing-block B and C, respectively, which blocks are adapted to move toward and away from the trunnions of the roller 0%. Each of the bearing-blocks has a downwardly and rearwardly directed bearing-slot D, which when the blocks are at the limit of their rearward movement are in alinement with the entering-ways f, permitting the insertion of the trunnions- E and F of an adjustable roller 'H, adapted to be carried toward and away from the roller m as said bearing-blocks are'reciprocated, and thus exert pressure upon or release any body entered between the adjacent surfaces of the rollers.

In order to move the bearing-blocks forwardly, and therewith the roller H, I arrange a cross-bar 1, whose ends project into the inin a similar manner.

closure of the inwardlydirected flanges of the plates Z) and c and engage the bearingblocks, as shown in Fig. 3 of the drawings. A second horizontal partition L and a bar K are mounted between the partition 9 and the top of the casing, and this bar K and the partition 9 have bearings in which is mounted an oscillatory shaft M, having an eccentric N fixed thereto or form ed integral therewith and adapted to engage the cross-bar I and press it forwardly as its shaft is rotated in one direction and to release the cross-bar when its shaft is rotated in the opposite direction.

In order to oscillate the shaft M, I mount loosely thereon an operating-lever O, connection being made between said lever and shaft through the medium of a spring-strap P, one end of which is connected with the lever and the other end of which is passed through a diam'etrical perforation in the shaft. Thus is formed a yieldable connection between the shaft and its operating-lever, and as a result a yieldable pressure of the roller H against the roller m.

In order to hold the lever O in its adjusted positions to maintain pressure between the two rolls or .to hold them at any desired distance apart, 1 form upon the bar K a notched segment R, adapted to be engaged by a projecting portion S upon the lever O.

The space above the partition L is divided to receive sliding drawers and also to form pigeonholes, as shown, or may be otherwise arranged, as may be desired.

In the operation ofmy invention the fabric 'n is drawn outwardly from the roller 'm to lie upon the inner surface of the lid j", which is brought to lie in a horizontal position, as shown in Figs. 2 and 3 of the drawings. The article to be mangled is then laid upon the cloth or fabric and the crank zfis operated, with the result that the roller 7% is rotated. At the same time the lever O is operated to move the roller H forwardly and into engagement with the said fabric, exerting pressure upon said fabric and upon the material carried thereby. After the article has passed between the rollers the rotation of the rollers is reversed and the article removed from the fabric, folded, if desired, and again passed between the rollers When the operation is completed, the lever O is disengaged from its holding-segment and the roller H allowed to return. This return may be assured or assisted by means of helical springs 'l and U, arranged between the forward edges of the bearing-blocks and stops V on the inner faces of the plates.

It will be readily understood that I may vary the specific construction and arrangement herein shown and described, that I may use whatever material may prove advisable for the different elements of my invention, and that I may equip the casing outside of the mangle-compartment as desired without departing from the spirit of my invention.

Having thus described my invention, what I claim is- 1. A mangle comprising a roller mounted in stationary bearings, j on rnal-blocks, a roller mounted in the journal-blocks, said journalblocks being adapted for reciprocation to move the second roller toward and away from the first roller, a cross-bar engaged with the journal-blocks, a shaft adjacent to the crossbar, an eccentric upon the shaft and adapted to engage the crossbar to move it to shift the journal-blocks, alever mounted loosely on the shaft of the eccentric, and a spring having one end connected with the lever and the other end connected with the shaft of the cocentric to form a yielding connection therewith.

2. A mangle comprising a roller mounte in stationary bearings, journal-blocks mounted for reciprocation with respect to the roller, a second roller mounted in the journal-blocks, a cross-bar engaging said blocks, a shaft journaled adjacent to the cross-bar, an eccentric upon the shaft and adapted to engage the cross-bar to move the journal-blocks, a lever mounted loosely on the said shaft, a spring connected at one end with the lever and at the opposite end with the shaft to form a yielding connection therebetween, and means forholding the lever at diiferent points of its movement.

In testimony whereof I affix my signature in presence of two witnesses.
