This invention relates to a steam generator which is designed and adapted for use in various devices for steaming, forming or shaping, and pressing fabrics, and various articles made of fabric including apparel and garments.

The principal object of the invention is the provision of a steam generator which embodies novel construction by virtue of which a unit is constituted enabling incorporation thereof in devices of the indicated character, also enabling replacement of a heating element constituting a part thereof without scrapping other parts unnecessarily, also giving an increased thermal efficiency so that steam is instantly generated and delivered upon repeatedly introducing quantities of water by suitable means connected therewith.

The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accompanying drawing, in which- Figure l is a side View of a pressing and forming device selected to illustrate the invention embodied thereby;

Figure 2 is an enlarged vertical section through the device showing certain features of the invention;

Figure 3 is a section taken on the

line

3, 3 of Figure 2;

Figure 4 is a section taken on the line 4, 4 of Figure 3.

Referring now more particularly to the several views of the drawing, it will be apparent that the steam generator of the present invention includes a metal body I of such size and shape that it may be arranged within a casing constituting a part of a device used for the various purposes mentioned. In the present instance, the body I0 is rectangular or oblong in shape. The body II] may be made of one piece, or may be made of separate sections, as in the present instance. As shown, the body II] consists of two sections, a section II and a section I2. Each section is of hollow construction to provide a space or chamber, the space or chamber in the section I I being designated I3 and that in the section I2 being designated l4. The space or chamber in each of the sections II and I2 is provided by boring a hole therein from one end, the open end being closed by a removable plug I5. The section II has grooves I6, while the section I2 has edge portions I! which fit into the grooves I6 respectively. Each section II and I2 is tapped near its upper end to receive a removable plug I8. When the sections II and I2 are brought together with the edge portions I I of the section I2 in the grooves I6 in the section II, a space T9 is formed between the sections II and I2 by reason of their cross sectional formations. The space I9 extends from one end of the body ID to the other. The sections II and I2 are fastened or secured to each other by suitable fastening element in the form of a screw 20 which is received in tapped holes in the sections II and I2 which are in alinement with the plugs 10 I8. The screw 20 has a bore 2I extending therethrough which establishes communication between the chambers l3 and I4 at a suitable distance above the bottoms thereof and thus forms one continuous passage within the body II]. The screw may be employed to fasten or secure the sections II and I2 to each other by removing the plug I8 of the section I2. The section II has secured thereto a water inlet 22 which communicates with the chamber I3. The inlet 22 may 20 be arranged at any suitable point, and in the present instance it is arranged at one side between the ends of the sections, as shown in Figure 3. The section I2 has a steam outlet 23 which communicates with the chamber I4 pref- 25 erably at the lower end thereof as shown in Figure 2. A conduit conducts steam generated within the body I0 from the chamber I4 to a point of delivery. The conduit consists of a copper tube 24 which is coiled about the body I 0 in contact therewith, and one end of the tube 24 is connected with the outlet 23, as at 25, and the other end 26 of the tube; projects beyond the body Ill. The body I0 is heated by electric heating element 21 of any suitable construction. The heating element 21 is designed to lit in the space I9 formed between the sections II and I2 in contact therewith so as to heat by conduction. The heating element is long enough to project beyond the opposite ends of the body I0, and is held in place with respect to the body III by the screw 20, the element 2'! being provided with a hole for that purpose, and the resistance coil of the element having certain of the convolutions thereof Widely separated to accommodate the screw 20 and avoid short circuiting. Certain con-' volutions of the tube 24 are also widely separated in order to afford access to the plugs IB so that they may be removed in order to remove the screw 20, when it is desired to remove the heating element 21 should the occasion arise to re place the same. Certain refractory or ceramic or other heat resisting material 28 is applied to the body I0 with the coils of the tube 24 embedded therein.

The steam generating unit hereinabove described is designed and adapted to be arranged within a steaming, forming and pressing device. In the present instance, by way of example, the unit is arranged within the casing 29 of a device for fonning and finishing scalloped edges of garments. This device includes a valve 30 secured to the casing 29 and connected with the water inlet 22 by a coupling 3|. The terminals 32 of the heating element 2'! are connected with binding posts 33 carried by the casing 29 and. insulated therefrom. The binding posts 33 project into a receptacle or socket 34 secured to the casing 29. Electric current is supplied by conductors connected with the socket 34. A water supply pipe is connected with the valve 30, the water being obtained from any suitable source. The end 26 of the tube 24 projects upwardly through the casing 29 into a former 35 detachably secured to an extension 36 and the casing 29, by a screw 31. The former 35 is one which is adapted to shape or form a scallop on the edge of a garment or the like when inserted therein with steam being caused to issue therefrom through passages 38 opening through one face of the former 35. The heating element has a hole to accommodate the screw 31, and at this point the resistance coil of said element has certain convolutions thereof widely separated in order to accommodate the screw 31 to avoid short circuiting. The end 26 of the tube 24 loosely fits in a bore in the former 35. The casing 29 has a removable section 39 in order to incorporate the unit within the casing and to permit the removal thereof.

From the foregoing, it will be obvious that the body l0 may be heated when current is flowing to the heating element 21, and that by manipulating the valve 3|] quantities of water will be introduced into the chamber 13 of the section II. The water is admitted at intervals and is instantly converted into steam by coming in contact with the walls of the section II. The quite moist steam flows from the chamber I3 into the chamber l4 through the passage 2|, where the steam is further attenuated and enters the tube 24 through the outlet 23. The tube 24 conducts the steam to the former 35 for the stated purpose. It will thus be understood that the objects of the invention hereinbefore mentioned may be attained.
