9 Claims.

This invention relates to garment and laundry pressing machines and has for its object a mechanism by which a fluid as steam can be projected on the garment and controlled either by a handle on the head of the machine or an operating member or pedal on the frame of the machine.

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

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

Figure 1 is a front, perspective view of a machine embodying this invention.

Figure 2 is a side elevation thereof.

Figure 3 is a detail view of the operating member on the head.

Figure 4 is a plan view of parts seen in Figure 3.

The pressing machine may be of any suitable form, size or construction, and as here illustrated, comprises a stationary buck I mounted on a bracket 2 which is supported on a frame 3.

l designates the head movable toward and from the buck the head being carried at the front end of a yoke lever 5 pivoted at 6 between its ends to a standard 1 rising from the frame. The head may be actuated by foot or power, but in the machine here shown, it is actuated by power mechanism comprising a cylinder 8 having a piston movable therein, the rod 9 of which is pivoted at it to one arm of an angle lever H, pivoted at H2 at its angle to the base of the frame, the other arm it of the lever being pivoted at M to the lower end of a link 55, the upper end of which is pivoted at it to the rear arm of the yoke lever 5. The piston is single acting, and the press is opened when the pressure in the cylinder 8 is released, by countersprings il E8. The flow of motive fluid to and from the cylinder is controlled by valve mechanism operated by a push button 20 and release lever 2 I.

The pressing machine thus far described, forms no part of this invention.

Garment pressing machines, as will be understood, are usually provided with means for projecting steam through the pressing face of the head to moisten the garment and the valve controlling the steam is carried by the head. Oftentimes, the operator is desirous of steaming the garment while holding the garment stretched on the buck so that it is awkward to operate the valve .on the head. This invention relates to means whereby the valve on the head is operable by a pedal when desired.

22 designates the valve which controls the flow of steam from the usual steam chamber in the head, to the usual chamber or channel which discharges through 'et openings 23 through the pressing face of the head.

24 is the movable stem of the valve located in a casing on the head to control the flow of steam from the steam chamber in the head to the channel in the head and from the jet openings.

28 is the operating member of the lever pivoted at 29 to a bracket 353 on the head and having an arm 3i arranged to push against the stem 24, the lever 28 having a handle 32.

33 is a pedal pivoted at 34 near the lower portion of the frame, this pedal being connected to the operating member 28 so as to operate the lever 28 and hence open the steam valve 22 when the pedal 33 is depressed. The connections between the pedal 33 and the operating member 28 are so arranged that the movement of the head 4 or the yoke lever 5 does not afiect either the pedal 33 or lever 28. Also, such connections include a one-way lost motion connection so located that the movement of the operating member to open the steam valve is independent of the pedal 33 and transferred to the stem 24 of the valve through the operating lever 28.

As seen in the drawing, the connections include an angle lever 35 pivoted at 35 to the yoke lever 5 eccentric to the axis 6 of the yoke lever t, the lever 35 having one arm 36 radial with the axial line of the pivot t.

The lever 36 is connected by a link 3i through suitable motion transmitting mechanism to the pedal 33, and the pivotal joint 38 connecting the link 3? and the arm 35 is located in the axial line of the pivot 5. The other arm of the lever 35 is connected by a link 39 to the lever 28 by a one-way lost motion connection. This lost motion connection comprises a slot ll] formed in the lever 28 and a pin ll on the front end of the link 39. Obviously, downward movement of the handle 28 will actuate the valve stem Without transmitting motion to the link 39, and that forward movement of the link 39 effected by depression of the pedal 33 will transmit movement from the link 39 to the lever 28 owing to the fact that the pin ll thrusts against the front end wall of the slot til.

The motion of the pedal 33 is transmitted to the link Bl through suitable mechanism comprising an angle lever 42 pivoted at 33 at its angle to the frame, one arm thereof being pivoted at 46 to the lower end of the link 3'! and the other arm being pivoted to one end of a link it, the other end of which is pivoted to an arm it on the pedal 33.

This steaming mechanism is particularly advantageous in that the operator can steam the garment either by operating a hand valve on the head or depressing a pedal on the frame.
