PRESSING IRON.
Application filed April 15,
The present invention relates to pressing irons and particularly to the type heated by gas, an object thereof being to provide a simple thern'iostatic control of the gas sup ply to maintain in the iron substantially a uniform heat. Another object of the invention is to provide a construction which will permit a thermostatically controlled valve to be operated manually.
In the drawings:
Fig. 1 is a plan view 01": an iron constructed in accordance with this invention;
Fig. 2 shows the iron in side elevation and partially in section;
Fig. 3 is a detail view showing the valve open; and
Fig. 4 is a similar View showing the valve closed.
Referring more particularly to the drawings. 1 indicates the body of the iron and 2 the handle. Between the main portion of the handle and the body of the iron, a plate 3 is provided, as is common, to keep the direct heat of the body away from the hand of the user. The iron is heated through a burner & arranged in the body and supplied through a conducting pipe or tube 6 to which combined air and gas mixed at a distant point is forced under pressure.
In the piping 6 a valve casing 7 is arranged which contains a valve member 8 controlling the passageway 9 through the casing. This valve member is normally held away from the seat 10 by a helical spring 11 surrounding the stem 12 on the valve member between the casing and a head 13 on the stem arranged exteriorly of the casing. This valve is very sensitive and is controlled by the thermostatic device.
The thermostatic device, in this instance, is in the form of a small strip 14: made of two metals having different coefiicients of expansion so that when subjected to heat the strip tends to bend, this being commercially known as a bi-metallic thermostat. One end of this strip is secured so that the heat of the body 1 that is heated from the latter will be conducted thereto while adjacent its other end, the thermostat lies in contacting relation with the head 13 when the valve is open and the strip 14 is in a straight condition or in a cool state. As the iron heats, this strip bends or deflects laterally, depending upon the amount of heat conducted thereto and tends to move the valve to reduce the 1925. Serial No. 23,182.
supply of fuel or gas passing through the pipe 6 tothe burner. The strip is flexible and should it be desired to close the valve 8 pressure thereon by the hand to bend it laterally will permit the manual closing of the valve.
The means for establishing conducting relation between this bi-metallic thermostat, in this instance, consists of a block 15 having two ears or projections 16 and having the strip fastened at one end in the block between the ears. This block has a reduced portion 17 passing through the plate 13 with a nut 18 on its lower end. This nut engages a screw 19 which is carried by the body of the iron so that there is direct heat conduction between the body of the iron and the block 15 which supports the bi-metallio thermostat 14.
In order to adjust the bi-metallic thermostat so that it may close the valve 13 at any desired temperature of the body, an adjusting means is provided comprising, in this instance, two screws 20 extending toward each other through the ears or projections 16 to cooperate with opposite sides of the bi-metallic thermostatic member 14: adjacent its lower secured end, so that the free end of said bi-metallic thermostat may be shifted. laterally in either direction toward or from the valve, thus varying its time of action on the valve.
From the foregoing it will be seen that there has been provided a simple and inexpensive means for controlling the supply of gas to a gas heated iron through a thermostat. This means may be adjusted in a simple manner so that any desired temperature may be maintained in the iron. It is so arranged that it permits the manual operation of the controlling valve, should such manual operation be desired. Not only does the invention maintain the iron in a uniform temperature, but it acts to save the gas a considerable amount.
WVhat I claim as my invention and desire to secure by Letters Patent is:
1. A gas heated iron-having a gas supply pipe leading thereto through the top thereof, a valve in said pipe having a horizontally movable plunger provided with an external ly arranged portion, a spring opposing the movement of said plunger for maintaining the valve in open position, and a bimetallic thermostat secured at its lower end to the w Gil projecting upwardly from the iron, a bi- 1 metallic thermostat secured to the block at its lower end and extending upwardly, its upper end engaging the externally arranged portion of the valve plunger, and two screws adjustable in the two ears to cooperate with 15 opposite sides of the lei-metallic thermostat.
