1 Claim.

The invention relates to a heated roll, and more particularly to oil heating means for mangle rolls used in ironing machines or other like machinery.

The primary object of the invention is the a provision of means of this character, wherein an ironing roll will be heated by the use of oil or other suitable liquid which will give the required or necessary heat without boiling or evaporating.

Another object of the invention is the provision '10 of means of this character, wherein oil or other suitable liquid is introduced into one end of the heated ironing roll and exhausting it at the other or opposite end of such roll and plenum or vacuum being employed sufficient to cause the oil 'or'other 3 liquid to flow at the necessary'speed through the roll, and a conduit being provided to carry the oil to the middle of such roll with branches or perforated pipes associated therewith to distribute the oil or other liquid equally in opposite directions 13 or to both sides of the median of the roll.

A further object of the invention is the provision of means of this character, wherein the oil or other liquid in its distribution within the roll will be maintained at a uniform temperature throughout the length of said roll, the oil or other liquid being distributed in both directions and also exhausted in both directions from the median of the roll and the distributing medium being stationary while the roll rotates so that a thorough agitation of the oil or other liquid is had.

A still further object of the invention is the provision of means of this character, which is comparatively simple in construction, thoroughly reliable and eflicient in its purpose, strong, dur- 1 3 able and inexpensive to manufacture and install.

With these and other objects in view the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in 4') the accompanying drawing which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is an elevation of the means construct- 4 ed in accordance with the invention and showing the heated ironing roll in vertical longitudinal section.

Figure 2 is a fragmentary sectional view on the line 2-2 of Figure 1, looking in the direction all of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail A designates generally the heated ironing roll which is in the form of a cylinder having fitted in opposite extremities end heads 11 and 12, these being pro-' vided with central hubs 13 journaled in side uprights 14, of the frame of a machine, for example an ironing machine. The roll A is rotated in any suitable manner from power furnished the machine. Concentrically disposed about the roll A is a series of closely arranged presser rolls 15,

these being suitably journaled in the uprights 14 of the frame to coact with the outer face of the mangle A during the ironing operation or when linen or other materials are mangled, the linen or materials being fed between the same from a stand or other support, as shown in Figure 2 of the drawing.

Arranged centrally within the-cylinderlo is a conduit 16, which is extended reversely through the journals or hubs 13 of the end heads 11 and 12, these being provided with stufling boxes 17 for the conduit. Spaced from the conduit 16 and arranged close to the inner face of the cylinder 10 and coextensive therewith and parallel thereto are perforated distributing pipes 18 and 19, re-

spectively, the pipe 18 being connected with the conduit 16 by the branch 20, while the pipe 19 is connected to this conduit by the branch 21,

these branches being on opposite sides of the median of the cylinder 10. The pipe 18 constitutes an oil or other suitable liquid distributor and the same is provided with a row of perforations 22 serving as outlets for heated oil or other liquid from the conduit 16 into the cylinder 10. The pipe 19 constitutes an exhaust from the cylinder 10 for the oil or other liquid and the same is provided with a row of'perforations 23 serving as outlets 9 therefrom. The conduit 16 between the

branches

20 and 21 is suitably closed preferably by a plug 24 so as to divide this conduit into an inlet stretch 25 for the oil or other liquid and an outlet stretch 26 for the exhaust of the oil or other liquid. The Q pipes 18 and 19 are held rigidly spaced by brackets 27, which are carried by the conduit 16, while the outer ends of the pipes are fitted with removable caps 28 for permitting the cleaning thereof. Located at a suitable point is an oil or other liquid heater 29 from which extends a feed tube 30 which is connected with the conduit 16 at the outer end of the inlet stretch 25 thereof so as to feed heated oil or other liquid thereto, and arm5 ranged within this tube 30 is a suitable themestat 31, which is also associated with the burner tube 32 so as to control the burner not shown of the heater 29, as will be obvious. Also this tube 30 carries a suitable gauge or thermometer 33 2 so that the oil or liquid condition can be determined.

Arranged spaced from the heater 29 is a suitable pump 34 which at its periphery has a lead 35 to the heater and this lead carries a strainer 36 and a hand operated valve 37, while extended from the center of said pump 34 is a lead 38, the latter being connected with the outlet stretch 26 of the conduit 16. The lead 38 close to the pump 34 has the connection 39 with an oil or other liquid supply tank 40, the connection 39 being provided with a hand operated valve 41, while the lead 38 has the connection 42 with anexpansion tank 43 provided with a sight tube 44 and the connection being provided with a gauge 45. The lead 38 is fitted with a hand operated valve 46.

Opening through conduit 16 and oppositely extending from and in alignment with the branch 21 is an air vent outlet 47, which extends through the outlet stretch 26 and also through the lead 38 to without the cylinder 10 and the outside end of this vent tube 47 is fitted into a valved cook 48.

The burner tube 32 is fitted with a hand operated valve 49, while the lead 38 carries a mometer 50.

In the operation of the roll A it will be apparent that oil or other suitable liquid which will give the required degree of heat without boiling or evaporating is conveyed from the heater 29 through feed tube 30 into the inlet stretch 25 of the conduit 16 whence it is distributed through pipe 18 into the cylinder 10 for the heating of the roll A and any gases or air formed therein due to agitation of the oil or liquid therein on distribution thereof will be drawn on through vent outlet 47 .on the opening of its cook 48 outside of the cylinder 10. The pipe 18 will carry the oil or liquid to the middle of the roll A and distribution will be had throughout the cylinder 10. Thus it will be seen that the heated oil or liquid enters the roll at one end and is exhausted therefrom at its therother end by the pipe 19, these pipes 18 and 19 being extended in both directions so that an equal distribution and exhaust is maintained and a uniform temperature had all along the length of said mangle, and the rotation of the cylinder 10 causes the agitation of the oil or liquid. The oil or liquid is supplied heated to the cylinder 10 under a plenum or a vacuum, and the temperature of such liquid or oil being regulated to meet the requirements of the work to be done by the roll A.

In the operation of the roll A the oil or liquid is caused to flow in the cylinder 10 at the necessary speed under the employment of plenum or vacuum.

From the foregoing it is thought that the construction and manner of operation of the invention will beclearly understood and therefore a. more extended explanation has been omitted.

It is to be understood that changes, variations and modification may be made in the invention, without departing from the spirit or sacrificing any of its advantages and as fall properly within the scope of the appended claim.

What is claimed is:

In fluid heated rolls. a cylinder, end heads fitting the cylinder and each having a central hub, uprights having the hubs journaled therein, a. conduit arranged centrally in the cylinder and extending reversely through the hubs, distributing pipes arranged close to the inner wall of the cylinder and parallel with the conduit, branches connected close to each other with the conduit midway of the cylinder and with the distributing pipes, a closing plug in the conduit between the branches, a heated fluid supply connected to one end of the conduit, an exhaust connected to the other end of said conduit, and a valved vent tube leading from within the-cylinder through a portion of the conduit to without said cylinder.
