lRONlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 518,871, dated April 24, 189 4,

K Application filed March 20, 1893. Serial No. 466,957. (No model.)

To aZZ whom it may concern:

Be it known that I, FREDERICK C. WEN- DELL, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements inIroning-Machines, of which the following is a specification.

This invention relates to ironing machines or mangles, and aims to provide an improved machine of this character which will be simple in its structural features, will occupy comparatively little space while having an extensive ironing surface, and in which a large proportion of the heat applied to the machine can be utilized in' the ironing operation.

Ironing machines have been constructed with steam heated drums, some rotary, about which the material to be ironed has been carried by aprons and rollers, and others stationhereinafter fully set forth.

In the accompanying drawings which illustrate certain adaptations of my invention, Figure 1 is a vertical section, between the frame and drums, of a mangle constructed according to the preferred form of my invention. Fig. '2 is a fragmentary plan view thereof, the apron being omitted. Fig. 3 is a diagrammatic elevation of a modified form of mangle, one half being broken away. Fig. 4 is a similar view of another modification, and Fig. 5 is a similar view of still another modification.

Referring to the drawings, let A indicate the framework of the machine, B the drums as a whole, 0 the apron carrying the goods to be ironed, D the feed roller over which this apron passes on entering the machine,E the delivery roller for the apron at the exit of the machine, F the usual adjusting roller for adjusting the tension of the apron and taking up the slack of either side thereof as usual, G G idler rollers for the apron, II a reefing roller between the idler rollers, I a rack for holding the reefing roller in its various posi- ;cording to my invention.

tions, which is of known construction, J another adjusting roller, and K the return idler roller over which the apron passes to the feed roller.

Referring to Figs. 1 and 2 I will now describe the preferred form of my invention. According to this construction Iprovide an oblong and substantially flat hollow steam drum having preferably convex opposite faces a b and a rounded end face 0, which faces constitute the ironing faces of the drum, being substantially .the entire outside thereof. The goods to be ironed are dragged over these faces by the apron, being carried successivel over the first face a and 'then across the rounded end 0 and back over the second face b. Preferably the entrance and discharge ends of the opposite faces are within the bulge of their convexity, and the apron enters and leaves in contact with these entrance and discharge faces, whereby by its tautness it maintains intimate contact of the goods against. the remainder of the convex portions of the respective ironing faces of the drum.

Preferably improved moisture escape grooves are provided in the ironing faces ac- Ihese grooves lettered d are preferably formed integrally in the metal walls of the drum and traverse laterally the entire width of the ironing faces thereof. In the construction shown one groove is provided in the face a and two in the face I), and the grooves are disposed at an inclination relatively to the faces, their openings in the faces opening toward the direction of movement of the goods over the latter, whereby the passage of the goods over the grooves is not resisted. Preferably the farther side of the groove is slightly rounded at its junction with the face to facilitate the passage of the goods. Any moisture driven from the goods while in contact with the drumcan escape through these grooves.

Preferably a pluralityof analogous sub stantially flat drums are employed, grouped together in as close proximity as convenient, and disposed in substantially parallel ing successively the respective faces of all the drums. Preferably the apron traverses the drum l3 first and B last, whereby the goods rise from the bottom to the top of the machine and are delivered at the top, traversing a. tortuous or circuitous path of substantially continuous ironing surface.

Various expedients for transferring the apron and the goods it carries from the ironing face of one drum to the adjacent face of the next drum may be employed. According to the preferred form of my invention, I provide transfer rollers carrying the apron and its goods from oneironing surface to the next. Preferably a plurality of these are employed, four being shown in Fig. l where they are lettered L L L and L respectively. The first carries the apron and its goods from the delivery end of the ironing faceb of the lower drum to the entrance end of the ironing face a of the succeeding drum. The next performs the same function between the two succeeding ironing faces, the next the same between the next faces, and the last L carries the apron and its goods from the top face of the drum l3 upwardly and free from the ironing faces. The apron passes over this roller and rearwardly over the delivery roller E, at which point the ironed goods may be removed in any suitable manner.

Preferably I continue the ironing surface around the transfer rollers by providing an intermediate ironing face 6 between each drum and the next, which at one end coincides with the face I) of the one drum, and at the other end-meets the face a of the next drum, whereby in their transit from one drum to the next the goods are substantially continuously ironed and the ironing surface is a substantially continuous, tortuous ironing surface. Preferably these ironing surfaces e constitute the walls of a steam jacket or drum,

giving a heating surface as well as an ironing surface. This maybe variously accomplished, butI preferto provide an auxiliary steam drum B one side of which embraces all the ironing faces 6, and the other side of which, as well as its end, is also utilized to form ironing faces f and g respectively. By disposing the other drums horizontally and the auxiliary drum vertically, the latter can embrace the ends of all the horizontal drums, all the transfer rollers, and provide a long substantially vertical ironing face from the top of the machine to the face aof the lower drum. Thus the goods entering at the feed roller D at the top of the drum B will traverse downwardly its ironing face f, then turn under on its face g, and go to and around the faces a c b and e of the respective drums before reaching the delivery end of the machine. Preferably the face f is convex, and the feed roller D is disposed inside the bulge of its convexity, whereby the apron presses against the greater part of the surface of this face.

Steam willbe admitted to the various drums, and the water of condensation withdrawn therefrom, in any suitable manner, as for example through the steam holes h and the outlets t for each drum, shown in Fig. 1.

My invention comprises an improvement in driving the apron O, which consists in making each of the transfer rollers a drive roller for the apron. This may be accomplished by driving these rollers by any suitable mechanical provision, but I prefer to use a spur gear N on the shaft of each roller, to provide idlers 0 between and meshing with these spur gears for communicating motion from one to the other, and drive pinion P meshing with one spur wheel or idler as desired for supplying the power to drive all. Thus the four drive rollers are disposed at points most advantageous for the peculiar sinuosity of the belt, and can be driven in a very simple manner.

I prefer to mount the transfer rollers yieldingly so that in case of inequality in the thickness of the goods ironedthere will be no danger of jamming at the circular ironing faces 6. To this end each roller is preferably mounted on afulcrumed slotted link Q, which receives the bearing j, of the shaft of the roller, in its slot, and carries a spring Z acting to force the bearing and roller toward the face e, this motion being arrested by the end of the slot in the link. Preferably each link is carried by an eye R, bolted to a corresponding cross brace S of the frame A. To permit a slight upward movement of, the transfer roller, I provide a slight hollow m in theironing faces e and a where they join above this roller, into which hollow the roller can ride when it yields upwardly.

The frame A shown, is constructed with a cross brace S for each of the horizontal drums, which drums are connected to the frame in any suitable manner as by theirlugs n which are bolted to the inner faces of the frame. To stop the downward movement and sustain the weight of the transfer rollers I prefer to tap a screw stop T into the frame under each link Q, by adjusting which stop the lower position of its transfer roller can be determined.

Preferably a guard U of thin sheet metal is provided to house the feed roller D, over which guard the goods are fed to the apron G.

In operation the operator will feed the goods to the apron over the guard U at the top of the vertical drum and the goods will then traverse the various ironing faces and be removed from the apron at the rear, preferably at the discharge roller E. The pieces of goods will be fed in one after another, and in their transit will be dried, smoothed and polished, leaving the machine completely finished. Any jamming of the goods at faces e, or any unusual tension of the apron, will be compensated by the yielding transfer rollers. The bends g c and e will be particularly effective in imparting a polish to the surface of the goods.

It will be seen that my invention provides an improved mangle which will be effective IIO in operation, lightin weight, exceedingly compact, and in which almost the entire surface of each heating drum is utilized for contact with the goods to be treated. By utilizing nearly the entire sides of the drums the necessity of covering them with non-conducting substances to preventwaste of heat is avoided, and the maximum results are obtained from the heat supply. By disposing the drums in such manner that the apron traverses over several sides of each, and arranging them as close together as will conveniently permit the passage of theapron and goods on their opposite faces, great compactness for a very extensive ironing surface results. In practice the machine shown in Fig. 1 gives an ironing surface in excess of thirty feet in length, while the length of the entire machine is less than eight feet and the height approximately five feet. The vertical and horizontal drums can be united together by bolts V at top and bottom, the intermediate drums of the horizontal series being in engagement with the vertical drum simply by grooved joining faces ,W.

It will be understood that the invention is not limited to the exact details of arrangement, construction, and operation, described and shown as its preferredform, as it may be availed of according to such modification as circumstances, or the judgment of those skilled in the art, may dictate, without departing from its essential features.

Fig. 3 is a fragmentary view of a modification in which only four horizontal drums are used, and the goods are shifted from the top face of one drum around the transfer roller transfer roller betweenthe two drums, and so on until at the last transfer rollerthe tapes ride ardund a return wheel X, from which they return over an idler X to the lower small roller \V". As the apron leaves the ironing face and passes onto the transfer roller the tapes W hold the goods against the face of the apron and move therewith from the lower to the upper side of the transfer roller, thereby preventing displacement of the goods on the apron, until they are in position for contact with the next drum.

Fig. 4 is a diagrammatic view of a simple modification in which the drum herelettered Y has two branches the lower one Y having convex lower ironing face and concave upper ironing face, over which faces the apron here lettered G rides, while the upper branch has a convex space against which the apron rides after traversing a roller lettered Y which transfers it from the lower to the upper branch. Presser rolls 10 press the apron against the concave face of the branch Y. The interiors of the several branches of the drum Y are hollow and in communication. The apron passes over the feed roller D along the ironing faces of the drum, around the discharge rollerE, and back/over an idler to the feed roller.

Fig. 5 shows a modification similar to Fig. 4 except that the drum here lettered Z has its branches constructed with plain fiat ironing faces, and presser rollers lettered q are employed for holding the apron lettered against all these faces.
