ASSIG-NORS OF ONE-.HALF TO MINNESGTA, A CORPGRATION.

AT/IERICN LINEN CIVIPAN Y,

OF MINNEAPOLIS,

LAUNDRY-1VIANGLE FEED-HOPPER.

Application filed June 1, 1915.

To zZZ whom t may concern Be -it known that we, FRANK M. OvannoL'r and ARTHUR G. (learners, citizens of the United States, residents of Minneapolis, county of Hennepin, State of lviinnesota, have invented certain new and useful lmprovements in Laundry-Mangle lieed-Iloppers, of which the following is a specication.

In the operation of a laundry mangle, it is customary to dump the clothes'as they come from the extractor into a hopper-*like receptacle in front of the mongie, where. they are picked out piece by piece and fed into the rolls. The hopper is usually filled to the top, or nearly so, and as the clothes are removed it is evident that the inangle attendants must stoop or reach down a little farther until the bottom of the hopper is reached. This constant stooping has been found to be tiresome and laborious and the Object of our invention is to provide means for raising the bottom of the hopper so that, as fast as the clothes are fed into the machine, the pile can be raised to a point within convenient reach of the attendants.

A further object 4is to provide a simple, inexpensive means for raising the hopper and its contents, which can be applied to any type of mangle.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure I is a side elevation of the forward portion of a laundry mangle with our invention applied thereto.

Fig. 2 is a plan view of the same, the middle portion of the mangle and hopper being broken away.

In the drawing, 2 represents the frame of the mangle; 3 and t the feed belts to which the pieces of Hat work, such as sheets, towels, and the like, are delivered .for passage over the steam ironing and drying rolls. 5 represents brackets projecting forwardly from the frame of the machine and 6 is a hopper, supported at 7 on, the frame of the machine and attached to a shaft 8 that is journaled in bearings in the outer ends of the brackets 5. This hopper preferably consists of a strip of canvas-or other suitable Specification of Letters 'Eatent Patented May 315, 1917. Serial No. 31,446.

flexible material, which will assume a sacklike form when unwound to its fullest extent and hold a large quantity of the clothes to be ironed. (lne member of a ratchet clutch 9 is secured on one end of said shaft S and the other member l0 is loosely mount-- ed thereon and normally held out of engagement with the member 9 by a tension coil spring 1l. A sheave l2 mounted on the clutch member l0 and has a belt drive 13 with a pulley 14.- on the shaft .l5 of one of the feed rollers. Normally this belt and the sheave l2 run idle. A lever i6 is mounted to engage the clutch member l0 and has an end portion 17 projecting outwardly where it can be conveniently engaged by the attendant standing in front of the hopper for forcing the clutch member l() into engagement with the other clutch member 9 to volve the shaft 8 and wind up the flexible hopper thereon to raise the clothes therein to a point where they can be conveniently reached by the attendant. Backward movement of the shaft is prevented by a ratchet wheel 1S and a dog 19. IVhen the clothes have all been removed from the hopper, the dog 19 may be disengaged from the teeth of the ratchet wheel and when a fresh supply of clothes is deposited in the hopper, the weight of them will revolve the shaft 8 and unwind the hopper, allowing` it todrop down to the position indicated in Fig. l, the ratchet clutch being, of course, disengaged automatically as soon the attendant releases the lever 1G. vided for the inner end of the lever 16.

We do not wish to be confined to the particular construction herein shown and de scribed for operating or supporting the lever in the front of the mangle, as in various ways these features may be modified and still be within the scope of our invention.

IVe claim as our invention:

l. The combination, with a laundry mangle, of a liexible hopper mounted in front of the same and means for winding up one side of said hopper to raise the lower portion thereof and lift the clothes.

2. The combination, with a laundry mangle, of a hopper mounted to extend transversely thereof and trough-shaped inform and adapted to contain clothing piled loosely therein, and means within control of an attendant for raising said hopper to A stop guide 2O is proelevate the clothes therein within convenient reaching distance as the pile in the hopper diminishes.

3. The combination, with e laundry mengle, of a hopper composed of flexible meterial supported et one edge over the mengle frame, e shaft Whereon the other edge of the hopper is mounted, end means connecting seid shaft with u moving portion of the mengle for raising the hopper and the clothes therein to a. higher level.

4. The combination, with en ironing meehine, of a hopper composed or' flexible muterial supported et one end of the machine frame, zt Shaft Whereon the other edge of the hopper is mounted, e driving connection between sind shaft and :L moving portion of the machine for raising the hopper und the clothes therein to e higher level, und a clutch inechunism'within Control of the attendent for rendering seid driving connection operative or inoperative.

5. The. combination, With e laundry man` gle, of e hopper composed of flexible me teriel and extending across the front of the mengle, a shaft mounted to Wind up one edge of said lieXible hopper thereon to elevate the clothes in the hopper, and meehenism within control of an attendant for revolving Suid shaft.

In Witness whereof, We have hereunto set our hands this 21st day of May, 1915.
