UNITED STATES SIGMUND SACHS, 01

Application filed September To all whom it may concern:

Be it known that I, SIGMUN'D SACHS, a citizen of the United States, and a resident of the Bronx, county of Bronx, and State of New York, have invented certain new and useful Improvements in Automatic. Stands for Electric Irons, of .which the following is a specification.

The objects of this invention are toprovide a stand for supporting an electric iron which will combine with the functions of a support, a simple and practical means for automatically cutting ofi the heating current when the iron is not in use.

Various other objects of the invention and the novel features of construction, combinations and relations of parts by which the same are attained will appear in the course of the following-specification.

In the drawing accompanying and forming part of the pecification, the invention is illustrated in a practical commercial embodiment but as such illustration is primarily for purposes of disclosure, it should be understood that the structure may -be varied and modified without departure from the broad spirit and scope of the invention as hereinafter defined and claimed.

Figure 1 is a brokenperspective view illustrating the stand in use and showing the one continuous cord circuit from the supply outlet through the automatic switch in the stand to the iron.

Figure 2 is a top plan view of the stand partly broken away to illustrate the switch and connections.

Figures 3 and 4 are longitudinal and transverse sectional views of the stand, the

latteras taken on line 4-4 of Figure 2.

Figures 5 and 6 are sectional and perspective detail views of the movable and stationary contact elements.

In the illustration 5 designates an iron of conventional design supplied with heat ing current by a flexible cord 6 provided with a plug 7 engageable with an ordinary outlet fixture 8.

As shown in the general view, the stand for the iron is interposed in the cord circuit.,-at a point to provide adequate length. of cord for conncction'with the outlet fixture and to provide sufficient freedom for ordinary ironing purposes. Where, however, greater than ordinary freedom is required, the iron may be. temporarily disconnected from the cord by simply detach- 6 1924. Serial No. $38,238.

ing the plug 9 which'connects the cord with the terminals of the iron.

The stand is shown in the form of a base plate 10 of the general shape of the iron and having upstanding side flanges 11 for guiding the iron to a proper seat thereon. For ventilation purposes, this base plate is supported in raised position, by a foot or lug 12 at the front and by a dependent wall 13 at the rear. This latter is continued around to form a switch chamber which is closed at'the bottom by a cap plate 14 removahly secured in place by screws 15.

Within the switch chamber and shown as secured to the under side of the base plate at 16 is an insulating base 17 carrying at its under side a pair of spaced

contacts

18, 19 arranged to be bridged by a contact 20 carried by a plunger 21 proiecting up through a guide passage 22in the insulating base and supporting base plate. This plunger is shown as positioned about midway or on the longitudinal center line of the stand adiacent the open rear of the same so as to be surelv engaged by the iron even though it be carelesslv placed or not fu l entered over the stand.

The movable contact is shown in the form of an annular washer having lu s. 23. turned in ard over a disc 24 of ins a ing m te fixe on the plunger and the lower.

end of the plunger is shown as of red ed diameter and operating through a guide opening 25 in the can plate.

A tomatic en a ement of the movable conta t with the ti ed contacts is e 'e terl in the illnstration hv a bowed spring 26 having a hearing on the cap plate and perforated in i s intermedia e portion to receive the reduced part of the plunger and engage I with the shoulder 2 on the plunger.

In. the rear wall of the switch chamber ofthe stand. insulating bushin s 28. 29 are mounted for passage of the single length of conductor cord which is all that is necessarv to use in this invention.

The stand can be wired hv simply removing the cap plate 14 and threading the cord to the binding screw 34 of the other stature,

tionary contact 19. The stand is tapped intothis cord circuit at-such an intermediate point as to leave plenty of cord to reaclrthe outlet and an ample length of the cord for use of the iron.

Because of its simplicity, few parts and manner in which it isv braced by the convergent side flanges l1 and the front and rear supports, the stand can be made quite light in weight. solidity and stability is desirable in a support of this character, a relatively heavy stud 35 may be extended down from the central portion of the top plate to serve both as a centrally located weight and as an extra foot for supporting the intermediate portion of the top plate. This foot prevents the top from sagging even when made of quite thin metal andprevents injury even if the iron-be dropped heavily onto the stand. By thus taking the shocks this toot serves to protect the switch strucli' additional solidity or finity is desired, the stand may be secured fast upon the ironing-board, table or other support by means of a suitable anchor screw extended up through the support into a screw seat 36' provided in the dependent weight and brace 35.

The switch plunger operates with a straight u and downv motion and beingguided at 0th top and bottom, shifts easily either with the weight of the iron to break the circuit or under impulse of the spring to close the circuit.

The guide flanges 11 usually will stand higher than the tip of the switch plunger serving as guards to prevent an object from falling over the stand and breaking the circuit and also as raised supports upon which the iron may be rested in case it should be found desirable to allow the iron to heat for a while, supported on the stand. lhe insulating washer which .carries the movable switch contact maybe fixed on the plunger by a screw threadedconnection, as

indicated in Figure 5, and as this plunger is free to, rotate it'may turn, in the use of the stand, to presentiresh contact surfaces to the stationary switch elements.

All of the switch arts are wholly enclosed within the switch chamber in the I bottom of the stand and so protected from mechanical injury, dust, moisture, etc., and the user of the device is fullyprotected against any possible injury; The convergent guardfianges uide the iron squarely into position over t e switch plunger with- As a certain degree of masses pendent walls at the rear of the same forming a chamber and support, a removably secured cover plate closing said chamber, an

insulating) base on the under side of the spring engaged over the lower portion of i the spindle hearing at its ends against the inside of the cover plate and operating to thrust the spindle upwardly to normally hold the plunger contactengaged with the stationary contacts.
