IRONING AND PRESSING MACHINE Filed May 18, 1932 2 Sheets-Sheet 2 Patented Nov. 27, 1934 UNITED STATES PATENT OF FICE' 10 Claims.

This invention relates to laundry machinery and more particularly to reciprocating frictional ironers.

Among the objects of the invention are:

Provision of means for retaining articles to be ironed in the desired position when in the ironer to prevent undesirable creases.

Provision for ironing every portion of the article within the scope between the buck and head of the ironer inclusive of the space covered initially by the retaining means.

Provision for frictional movement between the buck and head members under pressure the movement being effected manually at leverage advantage.

Variation of pressure to be effected for various angles of oscillation of friction members.

Other objects as will be set forth or.evident from the disclosure.

The invention accordingly comprises features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings in which Fig. 1 shows the ironer in side elevation;

Fig. 2 shows same in and elevation;

Fig. 3 is a sectional elevation view of the ironer while in operation.

Fig. 4 is a plan view of the retaining means Fig. 5 is a diagrammatic representation of the scope of movement of the ironer and retaining members.

In the preferred construction, a frame 10 has a base 11 and a boom 12. A stand'lB is mounted on base 11 and fixedly secured thereto or adapted for sliding along guides 14 on the base 11. The stand 13 supports a buck 15, and the boom 12 carries a head member 16 to cooperate with the buck for ironing. The preferred manner of mounting the buck 15 on stand 13 is as follows:

Slidably mounted in vertical position within the stand 13 is a plunger 17, which is preferably rounded at the bottom and has a lug 18 at its,

upper extremity. The buck member 15 also has a pair of lugs 19 which are adapted to rotatably fit over a pin 20 passing through lug 18. The buck member 15, which has a handle 21 at one end thereof, is thus adapted to be oscillated about pin 20 by moving the handle 21 up and down.

The rounded end of the plunger 17 is adapted to bear against a cam 22 keyed to the shaft 23 to which a lever 24 is also keyed so that the shaft may be rotated within the bearings 25 in the stand 13. The preferred positioning of the cam 22 and lever 24 are such that when the lever is moved downward, the cam 22 forces the plunger 17 upward effecting pressure of the buck 15 against the head 16. When the lever 24 is in its handle 39. To provide for vertical displacement of the head member 16 when it is oscillated from the horizontal position, the head member 16 is slotted at the pin 29 about which it pivots and is adapted to move against the action of a spring 30 preferably through the intermediary of a cap 31 slidably mounted in the carriage 27.

Preferably secured to one of the lugs 19 of the buck member 15 is a supporting frame 32 for the article retaining means 33. The retaining means comprises preferably a. plurality of flat bottomed fingers 34 mounted on a shaft 35 in the bearing 36 on frame 32, and tied together by handle bars 37, 3''! the shaft 35 being normally centrally maintained with respect to the frame 32 by means of the springs 38 which also apply the necessary pressure on the fingers. he shown in the drawing, the fingers 3d are preferably triangular in section, and a V-groove do is provided in the head member 16 to wholly accommodate the fingers 34. A heater 41 is provided on the head member 16 for heating same, the heater being preferably an electric heating unit, the plug d2, connected by wire 43 to a source of electric power, being used as a switch whereby to apply or shut off the heat.

The operation of the device is as follows:

Before pressing or ironing the garments, the buclr member 15 is exposed for laying the garment, preferably by pushing the head member 16 back to the position indicated in dashed lines in Fig. 2; or the buck may be moved forward along the guides 14 to expose it for garment laying. The retaining means 33 is raised and swung back out of the way sumcient to overcome the action of the springs 33, by being held in its raised position through the action of a stud 36 resiliently pressed by a spring 38 into a deep notch 32 in the shaft to hold the fingers against the torsion of springs 38 and the garment is spread on the buck. When the garment has been properly laid on the buck the retaining member 33 is applied to the garment, all wrinkles are removed and the retaining fingers keep the garment in the desired position.

In the preferred mode of operation the head member 16 is then brought forward by means of the handle 39 so that the head member 16 is directly over the buck 15. Pressure is applied by moving the lever 24 down so that cam 22 raises the buck with the retaining fingers as and the spring 30. In view of the balanced position of thefingers 34 by virtue of the springs 38, the grooves 40 are automatically in alignment with the fingers 34. Thus no wrinkles or creases are introduced into the garment as the head contacts the buck, because the fingers are not caused to be moved.

In this manner the garment is pressed while the heatis applied to the heater element 41. However, to obtain a finish or the equivalent of an ironer, all that is necessary is to move the handle 21 up and down several times, to obtain a friction movement of the head relative to the buck, whereby the friction and heat accomplish the purpose of the ironer. When the operation is finished, the lever 24 is raised to drop the buck. It will be noted that during the oscillation, the fingers 34 are caused to move with the head while the garment is under pressure, so that the portions of the garment covered by the fingers 34 are likewise ironed. The Fig. 5, shows the displacement of the fingers between the two extreme positions of the oscillating movement.

It will also be noted that increase in the amplitude of oscillation causes greater compression of the spring 30 and the increased pressure effected is transmitted uniformly to. the garment.

In this invention, the buck is readily movable for applying pressure or for moving same into pressing alignment with the head, without danger of spoiling the position of the article on the buck withconsequent possibility of forming undesirable creases. Once the retaining fingers are applied, the garment is held in position for all movements of the buck.

It will thus be seen that a simple, low cost structure is fully disclosed that is positive and simple in operation; that meets the requirements of practical use and whereby the various objects of the invention are attained. Of course many changes in construction and arrangement of parts can be made without departing from the spirit of the invention. It is therefore intended that all matter contained in this specification shall be interpreted as illustrative and not in a limiting sense, except as hereinafter claimed.
