17 Claims.

An object of my invention is to provide an osc ating iron for laundering, pressing and the like, which is simple, durable and comparatively inexpensive to man A further object ufacture. is to provide a tool having a heated sole plate which oscillates relative to the major portion of th e tool for the purpose of traveling over a much greater area of material being ironed or otherwise ment of the tool ac finished during normal moveross the material, thus reducing the amount of manual movement required in proportion to the actual over the material.

passage of the sole plate Still a further object is to provide a laundry iron or the like having a sole plate to which rotary oscillatory moveme nt is imparted, the sole plate being mounted for such movement on an axis perpendicular to the pressing surface of the sole plate.

Still a further object is to provide a compact iron comprising a casing having a manipulating handle, oscillatable sole plate mounted on and enclosing the bottom thereof and an electric motor carried by the casing and connected with the sole plate which is oscillated thereby during the operation of the iron.

Still another obi the handle of the iron ect is to provide a switch in connected with the motor vice, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing, in which:

Figure 1 is a plan iron embodying my view of an oscillating laundry invention.

Figure 2 is an enlarged sectional view on the line 22 of Figure construction.

Figure 3 is a det 33 of Figure 2 to the handle of the i only limited swiveling 1 to show internal details of ail sectional View on the line show a means for connecting ron to the casing and permit of the handle.

Figure 4 is an electro-diagrammatic view of the motor and heating Figure 5 is a pla construction showing shape of the usual element of my invention; and 11 view of a modified form of an oscillating iron of the domestic electric iron instead of one having a circular outline as shown in Figure 1.

On the accompanying drawing I have used the reference numeral It to indicate a sole plate. It

is circular in shape, being preferably upturned at its periphery as indicated at l2. An annular groove M is formed in the sole plate l0 within which I locate an electric heating element IS.

The heating element It is retained in position by a sheet of insulation l8 and a cover plate 20. Cap screws 22 are provided for retaining the cover plate 253 in position and clamping the sheet of insulation l 3 between the cover plate and the sole plate. 10

The plate 2B3 has a tubular extension 24 in which is located a pair of graphite bearings 26. These rotate on a stationary shaft 28 having a head So and mounted as by screw threading or the like in a hub 32 of a casing 3d. Thus the sole plate it is oscillatably mounted relative to the casing 3 3.

Mounted on the casing 34 is a motor 36. A gear casing 38 is connected with the motor 36 within which gear casing the shaft of the motor has a worm l!) which meshes with a worm gear 42 (see Figure 1). The worm gear d2 drives a crank shaft M journalled in the casing 38.

Within the casing 3d a crank 46 is secured to the lower end of the crank shaft 44 and is pro- 25 vided with a crank pin 48. An arm 50 is secured to the sleeve 26 and its outer end is connected by a link 52 to the crank pin 48.

From the construction of the parts just described, it will be obvious that rotation of the 30 crank 46 will impart oscillation to the arm 50 and consequently tothe sole plate I 0.

For controlling the heating element I6 I provide a rheostat switch 84 which is preferably of the snap acting type and operable to energize the heating element l 6 for low, medium or high heat as desired. -Within the casing 34 the circuit for the heating element l 6 includes a pair of flexible leads I l which permit oscillation of the sole plate. The switch a; is consequently located adjacent a manipulating handle 86 which is mounted on the casing 3 3 by means of a yoke 88, a swivel stud 90 and a bracket 92. The stud 90 has a semiannular groove 94 (see Figure 3), a retainer pin 9% extends through the bracket 92 for retaining the stud 90 in position yet permitting swiveling movementtherecf, this movement being limited to approximately a half revolution due to the fact that the groove 90 is not completely annular.

The yoke 38 is provided with a Wire carrying channel Q8 and the handle 86 is provided with a trigger portion Hill. The trigger is pivoted at I02 and is adapted when the handle is grasped to counter-sink into a channel I04 of the handle and in so doing to close the circuit through a When the handle 86 is released the push button moves back to the open circuit position, moving the trigger I00 with it. The push button I06 is connected in the circuit of the motor 36, thus providing an automatic control which de-energizes the motor whenever the operator stops using the iron by letting go of the handle. Flexible leads I08 extend from the switch I06 to the casing 34, these leads being looped as indicated at l08a to permit swiveling of the handle 86.

The current supply wires for the motor and heating element are indicated at IIO. These may extend to a yoke II2 secured to the casing 34. i

In Figure 4 I show a wiring diagram illustrating that the heating element and motor are independently controlled by their respective switches. The switch for the heating element is of the rheostat or some other type for obtaining different degrees of heat as desired.

In Figure 5 I show a modified construction in which the sole plate Illa and the casing 34a are in the shape of the usual household iron.

As shown by dotted lines the sole plate oscillates about the axis shown at 280. and the handle 86a is mounted in the usual position of domestic irons. The motor 36a and gear casing 380. are mounted ahead of the handle 86a. The internal construction and operation of the modified construction is substantially similar to that described in connection with Figure 2.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
