SADIRON.

application inea naveniber so, 192i. serial No. 'zassa My invention relates to sad irons, and particularly, although not necessarily, to sad irons containing an electrical'heatin unit,

and commercially known as electric sad irons.

It is a. purpose of my invention to provide an' electric sad iron having incorporated therein manually controlled means, by which steam can be generated as desired and applied to the cloth or garment during the normal pressing operation'of the sad iron, whereb a combined steaming and pressing of the clciith can be effected conveniently and expeditiouslv and to the elimination 4of the old method of employing a wet cloth for dampening. n e

I will describe only 911e form of sad 1r on embodying my invention and will then point out the novel features thereof in claims. J

In the accompanying drawings, Figure 1 is a view showing in perspective and partly in section one form of sad. iron embodying my invention;

Figure 2 is a view showing a iron in side elevation and in upright position;

Figure A3 is an enlarged detail perspective view of the water valve embodied in the iron shown in the preceding views y y Figure 4 is a bottom plan-view of the sad iron with a portion thereof broken away to reveal the electrical heating unit.

i Similar reference characters refer to similar parts in each of the several views.

Referring specifically to the drawings, my invention, in its present embodiment, comprises an iron body 15 conventional in form and having therein an electrical heatin unit '.16, the terminals of whichl latter are e ectrically connected to a conventional plug 17 extending upwardly from the upper side ofthe iron body and ada ted for connection with a conventional soc et member' v18 shown in dash lines in Figure 1, towhich latter are connected the usual conductors for supplying current to the heating unit, as will be understood. Fixed' to the upper side' of the iron body 15 is a frame comlprising a rear post 19 and a front post 20. ormed integral with the rear post |andl disposed horizontally is a cylinder 21, and this cylinder is secured 4to the-front arm 20 and is encased in a tube 22 of heat insulating material which is shaped to provide a handle adapted to be gripped in the operation of the iron'. rl'he rear end of the cylinder is closed by .a screw plug or head 23 having therein a check valve 24 open-l i knurled handle 28 which is adapted to'beA manually gripped in effecting reciprocation o f\tlie piston. The plug 25is provided with a port 29 for admitting air tothe cylinder to permit the proper operation of the piston.

The cylinder and piston constitute an air pump operable to place Water contained in a. tank 30 under pressureand to thus permit the discharge of water from the tank or reservoir in' relativelysmall quantities, in

order that it maybe converted into steam. I

' This tank 30 is secured to the rearend of the iron body by a bracket 31 embracing theA plug 17, the inner side of the tank conforming in part to the curvature of the rear end of the' iron body so as to have snug engagement therewith. The. outer side of the tank is inclined and provided at its far corners with projections 32 in order that it may function to support the entire iron in u right position when not in use, as clearly i lustratedin 'Figure 2. The tank 30 is provided with a filling plug 33 by which waterV may be supplied to the tank, and in such manner as to partly fill the tank so that an air chamberis provided above the body of. water, as illustrated in Figure 1. i The cylinder of the air pimp is in communication with the air chamr of the tank throughthe medium of a pipe 34 connected at one end to the rear end of the cylinder 21, and at the other to` the inner side of the tank 30 adjacent the top thereof.

The bottom of thev tank is provided with an outlet nozzle 35 having a relatively small restricted duct 36 for discharging i water in relatively small quantities into a pipe 37 extending longitudinally ofand within the bottom portion of the iron body, as illustrated in dash lines. This pipe 37 terminates adjacent the pointed end of .the iron body and communicates with a discharge port 38' formed in the bottom or working surface of the iron body, and diverging from this port are grooves or channels 39 in the bottom ofV the iron body designed for thepu'rpose of distributing steam projected 'from the port 38 over the working surface of the iron.

The discharge of water from the nozzle A35 los reservoir and working surface of the iron,

Y means carried by the iron and communicatingV with the reservoir for placing water in the latter under ressure, vand means for controlling the disc arge of water from the reservoir to the conduit, whereb water discharged into the conduit will, uring transit through the latter, be converted into steam by the heating means and discharged from the working surface of the iron.

6. A sad iron as embodied in claim 5 wherein the handle of the iron is hollow and said means for placing water in the reservoir under pressure comprises a manually operable aiipump the handle and having its 15 top and rear side thereof, the lower surface ofthe reservoir being spaced above the working surface of the body; and the rear side of the reservoir being substantially flat, whereby a stand is provided for the iron when the latter is 'in an up-ended inoperative posi- 26 tion.
