1' Claims.

This invention pertains to garment pressing machines, and more particularly to machines of that type wherein provision is made for spraying steam from the head or upper pressing element. More specifically, the invention relates to an improved valve actuating mechanism for controlling the flow of steam from the pressing face of the movable pressing element or head.

The main object of the present structure is to provide a. simple and eiiicient means by which the valve can be caused to open either through hand or foot manipulation. The structure makes for ease of operation which, of course, is particularly advantageous during hand actuation, and likewise ensures quick opening and closing of the valve, whereby the volume of steam as well as the time interval of projection thereof is wholly under the control of the operator.

The mechanism is illustrated in the annexed drawing, wherein:

Figure 1 is a vertical sectional view, partly in elevation, of a head steaming valve and the controlling or operating means of the present invention, the connection therefrom to the foot lever being broken away;

Fig. 2, a top plan view;

Fig. 3, a horizontal sectional view on the line IIIIII of Fig. 1;

Fig. 4, a fragmentary view showing the operative connections extending from the foot lever to the valve; and

Fig. 5, a transverse sectional view taken on the line V-V of Fig. 1.

The valve proper is of the type wherein the closure disc is unseated by steamv pressure when permitted so to do and, as shown in Fig. 1, is the same as that set forth and claimed in U. S. Letters Patent No. 1,942,987 to Sutton, to which reference is had.

In the drawing, l denotes a portion of the head of a garment press having a heating and pressure chamber 2 formed therein. The lower wall of the chamber 2 is denoted by 3 and spaced therefrom is a perforate wall 4 through the perforations of which steam is designed to be ejected. The wall 4 and the lower face of the wall 3 form what is commonly known as the spray chamber, here denoted by 5.

A steam dome 6 extends upwardly from the head and the chamber therein is in free communication with the heating and pressure chamher 2 into whichlive steam under pressure is introduced, as is usual. The valve body, denoted generally by l, is exteriorly threaded at its lower end and screwed into the wall 3, and is in open communication with the chamber A nut 8 and a sealing gasket 9, the latter resting on the upper outer face of the steam dome, secure the valve body in steam-tight relation with the dome, as in the Sutton patent aforesaid.

As will be best seen upon reference to Figs.

1 and 5, the valve body is provided with a central chamber ill in its lower portion, into which extend ports or passages II and I2 that are in direct communication with the steam space with- 10 in the-dome. The upper end of the wall in which the chamber I0 is produced is fashioned into a valve seat, as in the patent above mentioned. Longitudinally extending passages I3 and I4 extend from a point adjacent the valve seat downwardly through the body of the valve proper and terminate in the open lower end of the body, as in Fig. 1.

Normally, the valve is closed by a disc l5 mounted in the lower end of a plunger-like element 20 I6 which is free to reciprocate within the valve body. The upper end of the plunger is provided with a socket into which freely extends a. valve stem I! which, in turn, extends upwardly through a stem guide l8 screwed into the upper end of 25 the valve body. Stem I7 is free to move upwardly to valve open position when freed from restraint of certain mechanism about to be described.

As stated at the outset, it is desirable to operate the valve stem releasing mechanism, as it may 30 be termed, either through hand operation or "finger-tip" control, or through the operation of a lever pivoted upon the lower portion of the machine and designed to be actuated by the operators foot, so that the steam pressure may raise the valve from its seat and permit steam to flow through the structure. The finger-tip control mechanism for opening the valve is directly associated with and carried by the valve body proper, and the arrangement is such that the operator may cause the valve to open without removing his hand from the ordinary handle present upon the head of a garment pressing machine and employed to raise and lower the same.

The valve body 1 is formed with a shouldered 45 portion H! which may be employed as a medium to screw the valvebody in place as well as to form a seat or abutment for the lower face of an eye 2i formed upon the lower portion of a bracket denoted generally by 22. The eye 2| is held in 50 place between the members l8 and I9 when the member I8 is screwed'down to position, as clearly shown in Fig. 1. The bracket-like member 22 is provided with an upstanding portion formed by two separate walls or

elements

23 and 24, 55

5 at all times.

spaced apart, as best shown in Fig. 3, said walls merging at their upper ends and terminating in a laterally extending overhanging bracket denoted generally by 25 The extending portion 25 of the bracket has a vertically disposed spring pocket 26 formed therein in alignment with the stem H. A cup-shaped plunger 21 is mounted in the lower portion of said pocket and a spring 28 seated in said cup and hearing at its upper end against an adjusting screw 29, acts to force the cup 21 downwardly and into contact with a floating lever interposed between the cup and the upper end of the valve stem H. The lever is denoted generally by 3| and those portions thereof which are in contact with the cup and the stem are rounded and are denoted, respectively, by 32 and 33. This rounding of the parts affords ease of movement or operation of the elements with reference to each other.

At its outer end the lever 3| is pivotally connected to the lower end of alink 34, as at 34 the upper end of which is pivotally connected to the upper outer end of a bell crank lever 35 fulcrumed upon a bolt 36 which extends through the body of the bracket-like member 25. The bell crank lever at its lower end is connected to a link 3'! which, inturn (see Fig. 4) is connected at its opposite end to a second bell crank lever 38 pivoted at 39 to a fixed portion of the machine. The opposite end of said lever 38 is connected by a draw link 40 to a bell crank lever 4| mounted on a pivot secured to a fixed portion of the machine frame. The depending arm of said bell crank is connected by a link 4" to an upstanding arm 43 formed upon a foot lever 42. Said lever is fulcrumed at 43 and forward of the fulcrum there is a compression spring 44 which tends to rock the lever clockwise. The connections are such that the spring normally holds the lever 3| in the position shown in Fig. l with the valve closed. An adjustable stop 45 carried by the foot lever prevents the spring from causing over-travel of the parts.

Lever 3|, at what might be termed its inner end, extends between two fingers 46 and 41 formed by bifurcating the inner end of a valve release lever 48. A pin 49 extends through said lever 3i and the outer ends of the fingers 46 and 41 (see Fig. 3), and forms the pivotal connection between said lever 3| and the lever 48. Lever 48 is fulcrumed upon a pin 5| which extends through and is secured in place with reference to the

upstanding walls

23 and 24 of the bracket-like member, 22. i

A set screw 52 (see more particularly Figs. l and 3) is mounted in the lever 3| and bears directly against or extends into a seat formed in the through pin 49. Extending inwardly from each of the vertical portions of the

walls

23 and 24 is a lug, denoted by 53 and 54, respectively, which underlie the outerends of the pin 49 and under certain operating conditions provide: a ful-' crum for the lever 3| or, in other words, when said lever is operated so that its outer end is raised through the actuation of thefoot lever 42. When this foot lever is operated, the link 34 is elevated with the consequence that the lever 3| is rocked about the pin 49 as a fulcrum, the rounded portion 32 of the lever 3| forcing the spring pressed cup upwardly against the spring and permitting the steam under pressure to lift the valve from its seat, so that steam may flow from the pressure chamber to the spray chamber of the head. The moment the foot lever is released by the operator, the spring 44 will restore the parts to the position shown in Figs. 1 and 4, and the valve will be closed by the spring 23 acting through the lever 3| and the valve stem l'l.

When it is desired to open the valve through the depression of thelever 43, the operator without any necessity of removing his hands from the ordinary handle mounted upon the pressing head for raising and lowering the same, may by merely exerting a slight downward pressure by his finger upon a pad 55 secured to the outer end of the lever 48, rock said lever about its pivotal point 5|, thereby carrying the fingers and 41 and the pin 49 upwardly together with the adjacent end of the lever 3| which latter at such time fulcrums about the pivotal connection between its outer end and the lower end of the depending link 34. This carries the surface 33 upwardly and permits the valve stem I! to be moved upwardly and the disc i5 to be unseated by the steam pressure passing into the chamber l0.

Release of the head steam valve, through the depression of the finger-tip control lever 43 is dependent upon the presence of the spring 44 under the foot lever 43. The spring acts to hold the connected parts in place so that the outer end of the lever 3| where it connects, as at 34, with the link 34 will act as a fulcrum when the valve is hand operated. It will be appreciated that the valve might be released by the simultaneous operation of the hand and foot means, in which case the lever 3| is raised at both ends simultaneously, permitting the steam pressure to open the valve.

To control the volume of steam delivered by the head valve, a stop screw 56 is mounted in a finger 51 extending outwardly from the bracket 22. The stop screw underlies the lever and by proper adjustment limits the movement of the lever 48 and the floating lever 3|, which latter limits the degree of upward movement of the.

member I! and, consequently, the degree of opening of the valve.

As above indicated, the lever 3| is of the floating or two-way operating type, one end functioning at one time as the fulcrum point, and the other end at another time and through another operation functioning as the second fulcrum point.

It is thought that it will be appreciated from the foregoing description that the invention is simple in its nature. and in practice it has been found to bev susceptible of easy operation. The finger-tip control of the lever 48 is of marked advantage and, as a matter of fact, an operator once he becomes accustomed to the finger-tip" release will ignore the foot lever entirely unless,

perchance, the press head is thrown up to open position and he desires to hold the garment or piece of goods against the spray face of the head while utilizing both hands to steam the goods, at which time, he will use the foot lever 42 to effect the steaming operation.
