6 Claims. 1
My invention relates to pressing machines, and more particularly to heating means for a pressing machine having a movable presser head cooperating with a stationary buck. I his is a division of my co-pending application Serial No. 368,836, filed December 6, 1940, patented July 13, 1943, Patent No. 2,324,029, on Heating means for ironers.
In ironing devices such as pressing devices of the above mentioned character it is desirable to obtain a temperature of the ironing surface that is above 212 F. With the use of steam it would be necessary to increase the pressure to such a high point as to be dangerous, in order to obtain a temperature high enough above 212 F. to be highly eifective. Temperatures near 500 F. are often desirable in apparatus of this character, and in order to obtain temperatures as high as 500 F. with safety, it is necessary to utilize a liquid that has a higher boiling point than the highest temperature that is desired, so that no high pressures are necessary in order to get the desired heating value out of the heating medium. Such temperatures can be easily obtained by the use of oils or other'liquids, that do not deposit carbon, or other undesirable ingredients, at temperatures as high as that mentioned. It has been found that in order to get the desired heating effeet from a liquid heating medium, it is necessary to have constant interchange of heat between the liquid medium and the wall of the ironing member, such as can only be obtained by movement of the liquid over the wall of the member that is to be heated.
In order to accomplish such heating, I have provided heating means wherein a liquid can be heated and supplied to the pressing apparatus by any suitable circulating means, in such a manner that sufiicient pressure is provided that the liquid heating medium can be discharged onto the inner wall of the presser head on the opposite surface thereof from that which constitutes the ironing surface in a jet, or spray, but Without putting any high pressure on the liquid that might be harmful in case of leakage. The pressure on the liquid in the supply conduits suitable for the apparatus illustrated is between five and ten pounds per square inch, in contradistinction to much higher pressures now used in steam heated presser heads.
Pressing machines of the character herein referred to comprise a movable presser head and a buck. While the heating of the presser head is of primary importance, in such devices, it is also desirable to heat the buck to a certain extent,
and one of the objects of my invention is to utilize the liquid, that has been discharged against the wall of the presser head that has the ironing surface thereon, for heating the buck.
Other objects and advantages of my invention will appear as the description of the drawings proceeds. I desire to have it understood, however, that I do not intend to limit myself to the particular details shown or described, except as defined in the claims.
In the drawings:
Fig. 1 is a top plan view of the presser head of a pressing device utilizing my invention.
Fig. 2 is a section taken on the line 22 Fig. 1.
Fig. 3 is a section taken on the line Z-il of Fig. 1, on a slightly enlarged scale.
Fig. 4 is a longitudinal sectional View through one of the nozzles used, and
Fig. 5 is a transverse section through said nozzle, taken on the line 5-5 of Fig. 3,and being on a somewhat further enlarged scale.
Referring in detail to the drawings, the improved pressing machine comprises a buck BI and a movable presser head82, which is usually mounted to be swung into and out of super-imposed relation to the buck at, the particular mounting means being immaterial and not being shown. A suitable flexible conduit 83 extends to a connection with a pipe 34, said pipe 85 being connected by means of an elbow 85 with a pipe 86 that has a T 8? connecting the same with branch conduits 88, which are provided with suitable Ts and elbows for connecting the downwardly extending nipples 89 thereto, which are connected with the bushings 90, mounted in the wall of the presser head 82 in screw-threaded engagement therewith, and in which are screw-threadedly mounted the nozzles 9!. Four of such nozzles 9| are shown in the drawings, and it will be noted that these are arranged, preferably, near one side edge of the presser head t2, within the chamber 92, provided inside said presser head. A suitable discharge connection is provided at 93 in the presser head at substantially the lowest point of the same, along the other side wall thereof from that adjacent which the nozzles 9| are located, the discharge connection 93 being connected through a union 9 with a flexible conduit member 95.
The flexible conduit member 95 is in turn connected with a pipe 96, by means of a union 0?, which is provided with a T 98 and an elbow 99 leading to upwardly extending conduits E09, that are threaded into openings in the bottom wall 3 ID! of the buck 3| near one end thereof. A discharge connection I02 is located near the other end of the buck, extending through the bottom wall thereof, and connecting with a discharge pipe I03, which may lead away in any desired direction to return the liquid to the heating means. The liquid is discharged from the nozzles 9|, passes along the inner face of the bottom wall I04 of the presser head to highly heat the 'member III, which has a closed end wall formed by the disk-like member H2 welded into the end of the member 1H lying opposite the threaded portion thereof. A restricted opening H3 is provided in the end wall H2, and a plurality of restricted openings H4 are provideddn the side wall of the tubular member, as will be evident from Figs; 4 and 5, the side openings H4 being directed toward the side of the presser head having the discharge connection 93 thereon, and the opening I I3 being directed downwardly immediately below the location of the nozzle.
Itwill be obvious from the arrangement of the nozzles that a thinlayer of moving hot liquid willbe passing over the inner convex surface of the wall "14 over the entire area thereof from one side to the other thereof and from one end to the other thereof, flowing generally from the nozzles toward the sides of the presser head, and
more particularly toward the side having the discharge connection 93 thereon. Thus there will .be a rapid flow of liquid over the inner face of the'wall providing the ironing surface, and a discharge at high velocity of the hot liquid into.
engagement with said wall. At the same time the hot'liquid willbe utilized for heating the buck to the extent desired before being returned to theheating apparatus.
It will be obvious that the size of the openings H3 and 1 l4 and the pressure utilized, as well as the character of the openings, will determine whether a spray of the liquid is discharged therefrom, or whether jet-like streams of the liquid are discharged therefrom. Under the low pressures usually utilized, the openings shown in the drawings would produce a jet-like discharge, although if higher pressures are used the tendency to spray would be present. a
It is,' of course, to be understood that any suitable means for circulating the liquid may be provided, so that sumcient pressure is provided that the liquid will be discharged through the openings in the nozzles with sufficient force as to engage the wall 104 at high velocity. The pressure is, however, relatively small and is not such that there would be any danger of any breakage of connections in the conduits provided for the carrying of the heating liquid to and from the ironing member.
. In operation the presser head 32 is, of course, moved back and forth toward and away from the buck. In moving the presser head 82 away from the buck, it will move from the position shown in Fig. 3 to a substantially Vertical position, whereupon the heating liquid will drain therefrom through the flexible conduit into the buck. As this occurs at frequent intervals, this will prevent the building up of any pressure in the presser head and it will ordinarily not be entirely filled with liquid during any pressing operation. Ordinarily the presser head is in the vertical position for longer periods of time than in the position shown in Fig. 3 in the use of the mac i What claim is:
1. In an ironer, a buck, a hollow liquid tight presser head mounted to swing toward and away from said buck, said head having an imperforate bottom wall providing a concave ironing surface, and means for heating said wall comprising means extending into-and fixed relative to said head for directing liquidtoward and transversely of said wall toengage the inner convex side of said wall with a heated liquid at high velocity and pass a thin body of said liquid rapidly thereover and means for discharging :said liquid from said head uponswinging said head away from said buck.
