MORGAN, OF SAN FRANCISGO CALIFORNIA;
ELECTRIC HEATING DEVICE;
Specification of Letters Patent. Patented M 31; 1914,
Application filed November 6, 1912. Serial No. 729,902.
To all 1"]; am it may concern:
Be it known that I, MILTON H; SHOEN- uruc. a citizen of the United States, residing in the city and county of'SanFrancisco and State of California, have invented certain new and useful Improvements in Electric Heating Devices, of which the following is a specification.
The hereinafter described invention relates to a simple, effective, inexpensive and durable open mouth device for quickly heating water placed therein for use generally, although the device is more particularly designed for the heating ofthe contents of an auxiliary vessel placed within the outer vesscl and partly submerged therein, as, for instance, the heating of'the food or milk contained in a bottle,'the contents of which is used for the feeding of babies; the object of the invention being the providing of means for positively and quickly raising the temperature of liquid or water placed in the open month vessel, the providing of hand actuated spring controlled means for automatically cutting oil the electric current on the removal of pressure therefrom, and in the production of simple and effectual means for forming a sealed'joint between the lower end of the vessel and the base support therefor.
To comprehend the invention, reference should be had to the accompanying drawings, whercin- Figure 1 is a side elevation of the im-' proved heating device, with an auxiliaryvessel mounted therein. Fig. 2 is a vertical sectional view of the improved heating device with the auxiliary vessel mounted therein. Fig. 3 is a cross sectionalview taken on line rc-a'-Fig. 1 of the drawings.
In the drawings, the numeral 1 is used to designate any suitable form of a supporting base, and '2 a casing or outer shell held thereto. Preferably, the casing or shell is cylindrical in form and composed of any suitable material, n'cference being given to glass. At its lower end the casing or shell 2 is seated on a shoulder or supporting ledge 3 of a block 4 fitted within the ring flange 5 of the base 1, thesaid block being provided with a seat (5 for the reception of an expansible packing ring 7. I
From the base 1 projects a bracket 8, to which is secured an upwardly extended stud 9 carrying a handle piece 10, and to the upper screw-threaded end 9' ofithe stud or handle-post 9 is securedby means .of a nut.
10 the outer end of an arm or bracket 11. This bracket at its outer end carries a securing ring 12, which fits over the upper end of the casing or shell 2 and .holds the same properly positioned relative to the base section 1. and base form a holder for the outer container or shell of the heater.
Through the arm or bracket 8 extend the current'wire connections a-a, whichconnect respectively with the terminal posts b-Ji upwardly extended through the supporting block 4. On the said block 4 is seat.- eda coil holding block 13, the terminal posts 6-7) extending upwardly through bores cc in the block 13 and projecting within an annular groove 13 of the said block. Vithin the said annular groove 13 is seated'a resistance coil 14, the ends of which connect with the terminal posts b-?)' of the connections (t-(L.
Through the base 1 and a vertical bore 14 in the block l extends a clamp screw 14', the inner threaded end of which works within a countersunk threaded seat 15 of the block 13, which block rests on the packing ring 7. lVhen the clamp screws 14 are tightened during the assembling of the parts the block 13 is drawn downwardly toward the block 1, compressing the packing ring,
7 to expand the-same firmly against the inner wall surface of the lower end of the casing or shell 2 and by so doing making a closed orhermetical sealed unionjoint between the parts, the joint between the block t and the clamp screw 14 being closed by the ring washer 15 interposed between the blocks 1 and 13. I
On the projecting end portion 16 of the bracket 8 is slidably mounted a slotted sleeve 10', carrying a socket plug 17, said sleeve being normally held mitwardly pressed by the pressure of the spiral spring 17 mounted on the end portion 16 of the bracket 8 and bearingagainst the inner end of the sleeve 16. From the end portion 16 of the bracket8 project the contact posts18 and 18, which on the socket plug 17 being forced inwardly fit within the seats 19 and 19 thereof for making contact with theterminals of the electrical supply wires or connections 20 and 20 extended into the switch or socket plug 17 to close the circuit to the resistance coil 14.
The brackets, handle pieceheld inward by-pressure exerted on t e fin-V ger piece extensions'd, d, projecting .re-
' spectively from the bracket extension 16 and e plug 17 and while the extensions cl and d are held to ether manually the current flows through the coil 14. The momentpressureis released or removed'from the switch 'or socket plug 17, the pressure of the compressed spring 17 forces outwardly the sleeve 16' to take the contact osts 18 and 18' from within the seats 19 an 19' and by so doing breaking the electrical circuit.
The casing or shell 2 contains and holds the liquid or fluid to be heated, but where the heater is em loyed forheating milk or food products, t e same is placed in a container or auxiliary vessel 20? which is placed into the casing or shell 2 and partly submerged within the liquid contained'therein. This liquid is heated by the resistance coil 14 on the electrical circuit being closed, and saidliquid in turn transmits its heat energy to the partly submerged container or aux iliary vessel 20 for heating the contents thereof, the said container or vessel 20 be ing held securely in place by means of a packing ring 22 attached to the securing fhe described heating device will be found not onlyconvenient for use generally, but more especially so in connection with sick rooms, hospitals and for use in the heating at night time-the milk or food roduct for babies; the device being extreme y light and easily moved from place to place and the electrical connection being at all times under the control of the person using the same, the device is exceedingly useful in households and all places wherein it is required to quickly and economically heat liquids and 00d products.
Inasmuch as the improved heating device maybe quickly taken apart and the parts reassembled, access may be had at all times to the various essential parts for the cleaning thereof, thereby making a sanitary heater for the purposes desired.
I am well aware that changes may be made in the details of construction of the parts herein shown and described without creating a departure from the spirit and scope of the invention, and I do not Wish to be understood as so restricting and limiting the invention, the essential feature of which comprises a heating unit provided wit-h a resistance coil for the heating of liquid, the said heating unit being detachably secured within an open mouth outer shell or casing.
