To @l whom, t may con/007%.-

Be it known that we, ARTHUR L. WING- and ANDREW NORTON, citizens of the United States, residing at Boston, in the county of Suffolk` and State of Massachusetts, have invented new and useful Improvements in Ironing-Machines,of Which the following is a speciiication. l y

This invention relates to improvements in mangles or ironing-machines= and it is particularly Well adapted for mangling or ironing bedclothes, table-cloths, towels, napkins, or other Hat goods that do not require starching, and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure l represents a top plan view of the machine. Fig. 2 represents afront elevation, and Fig. 3 represents an end elevation, of the same. Fig. l represents a cross-section of the machine, partly shown in elevation. Fig. 5 represents a detail side elevation of one of .the sprocket-wheels, its chain, and endless apron.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A A represent the end frames, secured together at aproper distance apart by means of suitable stays or braces. Inabearing in one of said frames is journaled the driving-shaft B, preferably driven by belt-power applied to a pulley on said shaft, and to the latter is secured a pinion b, the teeth of which mesh in theteeth of a spurgear C, loosely journaled on a stud C', secured to one of the end frames. The teeth of the spur-gear C mesh in the teeth of the pinions D and E, which are secured to the respective horizontal shafts CZ ande, journaled in preferably vertically-movable bearings arranged in the end frames A A, -as shown.

F is an intermediate gear driven by the spur-gear C. Said intermediate gear F is journaled on a pin or stud f, secured to one of the end frames, and has its teeth meshing in the teeth of a pinion G, secured to a horizontal shaft g, journaled in preferably vertically-movable bearings arranged in the end frames A A, as shown.

To the rotary shaft cl are secured sprocket- Wheels D D', from which a rotary motion is conveyed to similar sprocket-wheels D D at the opposite end of the machine, as shown.l

The sprocket-Wheels D are secured to a shaft d', journaled in preferably vertically-mov- D3 D3 are endless sprocket-chains by which a rotary motion is conveyed to the sprocketwheels D from the sprocket-wheels D', as shown.

To the sprocket-chains Ds D is secured an endless apron consisting of lateral metal bars @Z3 d3, secured to the links of the chains in any suitable manner. Below the said Vendless apron is arranged a stationary fiat steamchest D4, between which and the under side of the said apron the cloth to be mangled o r ironed is carried. Such flat steam-chest is provided with steam supply and return pipes for the purpose of heating the same to the proper temperature as required` during the mangling or ironing process.

Between the top and bottom of the endless apron above described are located a series of vertically-movable gravity-rollers d4 d4 d4 for the purpose of holding the under side of the apron as well as the cloth to be mangled or ironed in proper contact with desired pressure against the top of the steam-chest, so as to obtain a great and superior finish on the cloth during the mangling or ironing operation. The size and weight of such rollers may vary according to the pressure desired, or they may be dispensed with altogetheras, for instance, the endless apron may be of sufficient Weight so as to produce the same effect. 4

In practice the bars da cl3 are covered or padded on their outside with cloth, felting, dac., so as to serve as a cushion to relieve the pressure on the goods in a manner similar to ordinary ironing-tables, so as to produce in this machine Work similar to or superior to ordinary handwork. In Fig. 5 we have shown such padding or cushion as consisting of a series of flexible strips d5 d5,attached in a suitable manner to each individual bar cl3 and lapping over one or more of the succeeding bars, as shown. In a like manner to the shaft g (which is arranged below the steamchest D4) are secured sprocket-wheels G', from which a rotary motion is conveyed to similar IOO sprocket-Wheels G, secured to a shaftg', preferably journaled in vertically-movable bearingsin the end frames A A, by means of sprocket-chains G3 G3,to which the endless apron,composed of the metal bars g3 g3, (shown in dotted lines in Fig. 4,) is connected, like the bars el? on the chains D3, hereinabove de scribed. In connection with said endless apron We use a series of vertically-movable gravity-rollers g4 g4, like the ones hereinabove described, and below said apron is arranged a iiat steam-chest G4, like the steamchest D4 on the uppermost mangle or ironing device.

Below the steam-chest or fiat steam-heated ironing-table G4 are arranged the rotary sprocket-wheels E E, secured to the respective shafts c e and provided with sprocketchains E3 and apron-bars c3, with hollow flat steam-chest E4, like corresponding parts hereinabove described. To the front of the steamchest D4 is secured a guide-plate D5 for properly guiding the articles to be mangled or ironed between the endless apron d3 and the fiat steam-chest D4, as shown in Fig. 4. At the rear end of said steam-chest D4 is secured a downwardly-projecting guide-plate D6 for guiding the cloths onto the endless apron g3. To the rear end of the steam-chest G4 is secured a guide-plate G5 for guiding the cloths between the apron g3 and steam-chest G4. To the front end of said steam-chest G4 is secured a guide-plate G6 for guiding the cloths onto the apron c3.

E5 is a guide-plate secured to the front of the steam-chest E4 for guiding the cloths between the apron e3 and steam-chest E4, and E is a guide-plate secured to the rear end of the steam-chest E4 for guiding the mangled or ironed cloths out of the machine.

During the operation of the machine the cloths are taken in a damp condition directly from the extractor or wringer, and by being passed between the successive traveling aprons and their steam-heated flat chests such cloths are caused to he automatically dried, mangled, or ironed on both sides, as described. It will be noticed that as the cloths pass from one apron and steam-chest to another in the series they are reversed-- that is,the position of such cloths is reversedcausing them to be dried, ironed, or mangled on both sides.

What we wish to secure by Letters Patent and claim is- 1. In amangle or ironing-machine, the combination with a series of flat steam-tables arranged horizontally one above the other, of sprocket-wheels arranged at the opposite ends of the tables, endless metallic aprons carried by said sprocket-wheels in contact with the upper sides of the tables,and reversely-curved rigid guide-plates iXed to the opposite ends of the tables and operating to guide the cloths from beneath one apron and deliver them under another, substantially as described.

2. An apron for mangles or ironing-machines, comprising endless chains, metallic bars arranged transversely and secured to said chains, and flexible strips attached to the outer sides of said bars and overlapping each other and said bars at their free ends, substantially as described.

In testimony whereor` We have hereunto set our hands in presence of two subscribing witnesses.
