. MICHAEL A ROLLMAN, OF, MOUNT JOY, PENYSSYLVANIA EL CTRIC snnrnon Application filed January 14, 1928, Serial N tasha. Renewed. June is, 1921..

The object of this invention is to provide simple means whereby, when the iron is in the iron;

normal position, the current, will be oil, so

that the iron will not be heated and will,-

therefore, be safe as regards accidental fires, means being provlded whereby the operator,

while using the iron, may conveniently hold the current on whenever she wishes to do so,

means also being provided whereby she may keep the current on in the iron even when she is not using it if she desires to keep the iron hot ready for use, as more fully here- I inafter set forth.

In the annexed drawings Fig. 1 is a side elevation of iron; v r a Fig. 2 is a similarview showing the iron set on end, in heating position;

Fig. 3 is a plan View of the rear-end of Figs. 43 to 11, inclusive, are views of details I hereinafter described; j

Referring to the annexed drawings by refcreme-characters, designates two wires leading up from the heating-element located within the body of the iron (not shown herein), part of which is-shown at 16, Fig. 4. These two wires lead "down into the ironbody through a pair of insulating-blocks 17 removably attached to the rear-end of the iron by means of screws 18. These two wires 15 lead up intothe handle to a switch mechanism hereinafter described. From the switch mechanism, these two wires pass out plug-and-socketqdevices employed in this type of iron. These plug-and-socket devices have well-known disadvantages and, there fore, my arrangement of'the conductors completely does away withall the problems con nected with the plug-and-socket method of.

connecting the the iron-body.

The handle is conductors to the rear-end of constructed of a plurality of plates 22 secured together by transverse my improved screws23 and spaced apart from each other by means of bosses 24. Thus spacing the plates 22 away from each other forms open air-channels which tend to keep the handle cool and also provides convenient housings for the switch-members andthe' conductors hereinafter described. y P

YVithin the central space, i. e, between the two inner plates 22, is mounted a fiat bar 25 7 whose rear-end extends out beyond the rearend of the handle and whose forward end extends to a point some distance in front of the central one of the screws 23. In a slot 26 there is mounted, a retractile spring 27 which tends to pull this plate-bar25 rearwardly.

Slots 28am formed in this plate in position to embrace the {bosses 24:- surrounding-the screws 23 and thus serveto guide the bar 25 in its back-and-forth movements Attached tothe forward-end of bar 25 is a forwardlyproje-ctizig finger 29 of insulating. material, and through this insulating-piece extends a short metallic contact member .30 whose pro jecting endsare rounded;

1 he'plate 25 is adapted r0 manually projected forwardlyby means of a finger- "l'ever 31 pivotally mounted at 32 at a point between, the two central handle-plates 22.

Depression of the finger-piece32, whichlpro jects above the handle, serves to slide the plate 25 forwardly, and removal of the finger from this finger-piece 32 permits the spring 27to automatically return it to normal posi-V tion, as shown in Figs. and 9 7 When the bar 25 is thus slid forwardly, its contact 30 bridges the two contact-springs 33 mounted in. the spaces, respectively, between the central-plates 22 and the outereplates 22'and normally projecting into the central space.

through slots 34 formed in the two centralplates'.,. These two free ends of the springs 33 springfar enough inwardly to bearlightly againstthe forward end of the insulatingmember 29 when'the parts are in normal o position, so that, whentheplate 25 is pro;- jected forwardly, the springs will be electrically connected throughthe'. medium of the is'co-nnected to cable 20,. while the other wire of the cable20 is one of the wires -15, heretobridge-contact 30;' One of these springs 33 fore described. The other wire 15 lies in the space at the other side of the handle and is connected to the other spring 33, so that, when the finger of the operator depresses the finger-piece 32, the metal bridge-contact 30 will move forward and close the circuit across the springs 33 and thus provide the heating-element in the iron with current. WVhen the finger is removed, the parts return to normal position and the current is automatically cut off. The current may, however, be maintained in the iron by setting it up on its rear-end, as shown in Fig. 2, in which position the weight of the iron will force the plate 25 forwardly in the same manner as depression of the finger-piece 32 and hold it in its forward position so long as the iron remains in its upset position. To give the proper angle to the iron when thus upset, i. e., to bring its weight sufficiently upon the switch-plate 25 to force it forwardly, I provide the rear-end of the body of the iron with a prop 35. To insure at all times, even after considerable use, a good contact between the springs 33 and the contact 30, I provide each one of the springs with a coil expansible spring 36, each of which abuts against one of the outer-plates 22 of the handle and presses against the free end of the adjacent spring.

For the purpose of decreasing the friction incident to sliding the bar 25, I prefer mounting upon the bosses 24 roller-sleeves 38.

In accordance with the provisions of the patent statutes, I have herein described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiments thereof, but I desire to have it understood that the apparatus disclosed is only illustrative and that the invention can be carried out by other means. Also, while it is designed to use the various features and elements in the combinations and relations described, some of these may be altered and others omitted and some of the features of each modification may be embodied in the others without interfering with. the more general results outlined, and the invention extends to such use.

hat I claim as new is: Y

1. An electric sad iron embodying an electric heating-element, electric conductors extending into the handle, and a normally-- open switch mechanism enclosed in the handle embodying a finger-piece extending outside of the handle at the forward end thereof beyond the grasping portion of the handle, means being provided at the rear-end of the handle for closing the switch when the iron is set up on end.

2. An electric sad iron embodying a heating-element and a switch mechanism located in the handle thereof holding the circuit normally open, said switch mechanism embody signature.
