3 Claims.

This invention relates to garment finishing boards or what are usually called spotting heads. It is of the general type shown in the application-of Don O. Goodwin of St. Louis, Mo., Serial Number 549,383, filed August 14, 1944, which issued on January'13, 1948, as Patent No. 2,434,404.

The. invention has for its object a particularly simple and compact apparatus, wherein dry steam, moist steam and also preferably compressed air can be projected through the garment or article on the spotting head down through the head, at the will of the operator, and the dry steam and the air pass through a heater or heat exchanger on its way to the nozzle while the moist steam, which is added to thedry steam to give it the amount of moisture that may be required, lay-passes the heat exchangerfor the dry steam, the heat exchanger being located in heat exchanging relation in a steam receiving chamber from whichboth the dry steam andthe moist steam is taken.

The invention further has for its object operating members for valves controllingthe dry and moist steam systems or conduitsand the air systemor conduit, the operating memberfor the control valves. for the dry and moist steam systerns being. common to both and operable to successively open. the valves in the .dry and. moist steam system at the willof. the operator, so that when the dry steam system is first turned on, if it is too dry andrequires moisture, additional operation of the commoncontrol member opens the moist steam valve, adding moisture to the dry steam.

It will be understood that in removing spots from garments and other articles, the use of dry steam and. moist steam is dependent upon the skill of the operator, and oftentimes the dry steam must be moistened an. amount determined by the operator, and hence one operating member for both the dry steam valve-and the moist steam valve greatly facilitates the removal of the spots, also blowing heated air through the nozzle greatly facilitates the drying out of the area from which the spot has been removed.

The invention consists in the novel features andin the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. 1

Figure l is a longitudinal, vertical sectional -iew of this spotting apparatus.

Figure 2 is an end view looking to the left. in Figure 1. I t

l designates the so-called spottinghead, which is supported by a column 2 rising from a base 3. This head, in so far as this invention is concerned, may be of any suitable form, sizeiand construction. It is here shown in the form of a "board overhanging the beset. It has a perforatedtop at the left end portion or half on which the-garment or article is. laid, this tophaving a. brush, as in said'application referred to, and a hollow chamber-or passage into which the steam and'air passing through the spot are projected- The passage in the head I: has a suitable discharge outlet. 1 V, 1

l designates the nozzle or the-so-called steam gun, although in this apparatus, it isalso an air gun to project air through the articleon the head I. The nozzle has connected thereto a flexible conduit or hose 5 connected in or commonto the dry. steam, moist steam and compressed air systems. It is provided with a suitable grip ,han-

dle B to manipulate nozzle 4 over the garment. lhe dry steam system includes a receiving or heating chamber 8 which is here shown aswithln the column 2, the .columnbein-g form-ed hollow for the purpose of providing this chamber 8,.a. steam supplyconduit or pipe 9 opening at in into the column, an outlet pipe ll leading from a. port l2 near the topof the column, a transfer pipe l3 leading from the pipe I! to the lower end. of a heat exchanger or coil 14 in the chamber 8, the upper end of which coil isconnected through suitable couplingslE, I B to the hose. 5. Av dry steam control valve ll islocated. in; the pipe. ll between the port I2 and the receiving end of a transfer pipe l3, this valve being normally closed.

When is open, however, the steam. passes from the chamber 3 throughthe pipe l I, open valve ll, transfer pipe l3, thence through suitable couplings it to the lower end of the heating. coil Hi, and thence through couplings. l5, Hi to the hose 5 to the nozzle through which the steam is projected when the pedal 1 is operated. The chamber 8 is also provided with a return pipe l9 leading from the lower end thereof back to. the steam supply or boiler. Moisture or condensation the steam flows out through this pipe. The moist steam system comprises a conduit ZUleadfrom the return pipe lQ-and having a control valve 2i therein which controls the flow through pipe 22 directly to the flexible hose 5 of the nozzle l, this conduit 22 thus b-y-passing the coil I l. As the moist steam conduit leads from the return conduit, it carries moisture therewith, and hence coupling at the inner end of the hose 5.

when the valve 2| is opened, moist steam passes through the nozzle 4, and as will be apparent, mixes with the dry steam, because of the two valves I! and 2| being successively operable by an operating member, as the pedal 1 is common to both.

The air system includes an air supply pipe 23 which, through a valve 24, communicates with the pipe l3 leading to the lower end of the heating coil l4, so that when the air valve is open, the air passes through the coil l4 and picks up heat, while passing to the nozzle 4 through the hose 5. As this conduit I3 is common to both the dry stream and the :air, a check valve 25 is provided set to prevent the steam from normally passing into the air pipe. As the pressure on the steam supply is greater than on the air, this check valve will open to the flow of air when the air valve is opened and the steam valve closed. This check valve may be of any suitable construction.

The operating means for the valves I'l, 2| and 24 include an operating member common to the dry steam valve I! and the moist steam valve 2! to operatethem successively and an operating member individual to the air valve 24. The operating members are here shown as pedals 26, l

' mounted respectively on concentric or nested rock shafts 29, 28, the rock shaft 28, which is operated by the pedal 1 being connected through suitable motion transmitting means to a lever 30 pivoted to a suitable bracket on the body of the valve ii "pipe l3, coil or heat exchanger l4, hose to the nozzle 4. Upon the initial movement of the pedal 1, the valve I1 is opened. The motion transmitting means is here shown as a cable or chain 3'2 connected at one end to the lever 30 and at its other end to a rock arm 33 on the rock shaft 23.

:The moist steam valve 2| is operated from this same pedal 1 through the rock shaft 28, rock arm 33, chain or cable 32, lever 39 and link 34 connected to a lever :35 pivoted to a suitable bracket on the body of the valve 2| and having an arm I31 which thrusts against the stem 36 of the movable member of the valve 2|.

There is a lost motion in the connection between the levers 39 and 35, and as here shown, the link 34 is adjustable as to its length, in order to space the arm 3'! of the lever 35 away from the end of the stem 36 a sufiicient distance so that the valve 2! is not opened until after the pedal 26 has been depressed a predetermined amount sufiicien-t to open the 'steam valve Il. Then continued movement also opens the valve 2| permitting moist steam to flow from the bottom of the member '8 through the pipes I9, 20, open valve 2| and pipe 22 to the Thus, when the operator notes that the steam is too dry and moisture is necessary to soften or remove the dirt particles of the spot being removed, he depresses the pedal further to permit the moist steam to mix with the dry steam. The coil or heat exchanger I4 normally acts as a drier for 4 to the lever 39 and to a rock arm 4| .on the rock shaft 29. The lever 39 is similar to the lever 35 and operates the stem 42 of the movable member of the air valve 24. Thus, after the spot has been softened and removed, the spotted area is dried by directing the nozzle 4 against that area and shifting the foot from pedal 1 to pedal 26, permitting the airto pass through the pipe 23, air valve 24, past the check valve 25, thence through the pipe I13 and the heating coil or heat exchanger I4 and through the hose 5 and the nozzle 4. The steam and air, after passing through the article, passes into the head I, which is hollow, and out through a suitable outlet pipe.
