` `7 claims. (ci. azz- 74) 10 and inadvertently fails to turn onf` the electric current.
Another object ofl this invention is to provide a self-raising atiron which may be locked in its closed, operative position, if so desired, during l 15 the working period or for the purpose of storing `the ilatiron away.
A further object ofthis invention is to provide a. self-raising iron which is eicient in performing its particular function and which can be manufactured at relatively low cost. l Additional features and advantages of this invention will appear in the following description I considered in connection withthe accompanying drawing forming part of this application.
In the drawing:
Fig. 1 is-a longitudinal sectional view showing one embodiment of my invention.
Fig. 2 isa perspective view of the used in Fig. 1.
Fig. 3 is a perspective view of a cam lever also used in Fig. 1.
Fig. 4 is an enlarged sectional'view of one of the spring-supports employed in the embodiment shown in Fig. 1.
Referring to 1 in particular, the atiron- This atiron is mounted ona sub-base 8 being 4 yieldingly supported by, preferably, three supporting-springs 9, resting on bosses I0, provided on the sub-base and vbearing against the inside of the cover 6. Guide-sleeves II, screwed on the bosses I Il, are used to prevent buckling 'of these springs and also/to protect them somewhat from exposure to the intense heat ,produced bythe heating element. As shown, suitable holes are provided in the base, heating element, and core to freely accommodate these sleeves and the latsub-base ter are provided at the top with flanges I2 which serve as stops limiting the upward lift of the latiron proper, by contacting the bottom of the enlarged recesses I3 formed in the core. If de- I sired, a post I4, extending through the fiatiron proper, may be screwed into the sub-base to act as a locking device to releasably hold the base I in close contact with the sub-base 8. This post is provided with a notch I 5 which may be engaged by thetapering cami6 provided on the lo cam-lever Il rotatably mountedton the bolt t and held in place by the bolt-nut I8. l
The aggregate strength of the supporti-ng springs 9 is slightly greater than the weight of the fiatiron proper, so that only a light down- 15 `.On the other Ihand, as soon as said `pressure isremoved, the springs will force the iron up and provide suicient clearance between it and the sub-base to .eliminate all danger of scorching or burning the goods that is being ironed, Preferably, the flange I 9 of the sub-base is suitably perforated, as at 20, to facilitate increased circuf lation of air between the sub-base and the iron, when the latter -is in its raised, inactive position. It will be noted that when the flatiron is de pressed on the sub-base, vthe downward sides of the cover 6 practically cover the perforations thereby reducing the loss of heatv and thus concentrating. same on the sub-base. When the cam-lever is in the position shown in Fig. 1, that is, substantially cross-wise of the fiatiron, the caJn-ange of the lever does not engage the notch I5 in the post Hand, therefore, 35 u notch` and, owing to the bevelled shape of the 40 former. the atiron andthe sub-base will be forced and locked together into intimate contact to facilitate the transfer of heat from the base I to the sub-base 8.
1. In combination with a ilatiron, a sub-base having a peripheral flange arranged to freely receive, surround, and guide the base of the atiron and adapted to rest on the goods being ironed, and spring actuated means mounted on 50 the sub-base to lift the fiatiron above' the subbase when pressure thereon is removed.
2. In combination with a flatiron, a sub-base having a peripheral flange arranged to freely receive, surround, and guide the base of the flatiron and adapted to rest on the goods being lroned, and spring means mounted on the subbase to lift the flatiron above the sub-base when pressure thereon is removed, the peripheral flange 6 of said sub-base having apertures to increase the circulation of air between said base and subbase.
3. In combination with a flatiron, a sub-base therefor adapted to rest on the goods being 10 ironed; means positioned on the sub-base to automatically lift the flatiron above said sub-base when pressure on the atiron is removed, and means to lock the flatiron in contact relation with vthe sub-base. 15 4. In combination with a atiron, a sub-base therefor adapted to rest on the goods to be ironed; spring means positioned on the sub-base to automatically lift the flatiron above said subbase when pressure on the atiron is removed; a 20 cam-lever rotatably mounted on the atiron; a post mounted on the sub-base and having a notch engageable by the cam-lever to lock the atiron in contact relation with rthe sub-base.
5. In combination with a atiron, a sub-base 15 therefor adapted to rest on the Agoods being ironed; spring means positioned on the sub-base to automatically lift the flatiron above said subbase when pressure on the atiron is removed; a lever rotatably mounted on the flatiron; a ta.-
pered cam on the lever; a.I post mounted on the.
lation .with the sub-base and vary the pressure.
7. In combination with a atiron, a sub-base therefor adapted to rest on the goods being ironed; means positioned `on thesubv-base to automatically lift the atiron abovesaid sub-base `when pressure on the atiron is removed,l and unitary self-locking means to lock the atiron in contact relation with the sub-base and gradually vary the pressure thereon.
