Application fried' october' 2 This invention relates to heaters, and more particularly to devices of this character which may be employed on vehicles',.particu larly automobiles, for the purpose of heating bottles or the like.

The object of the invention-is to provide a heater of this type and character which is simple in structure, efficient in loperation and economical of manufacture, installation and maintenance. Y

A further object of the invention is to prof vide a heater of this typewhichis electrically4 operated, and which becomes operative whenthe vbottle or other. receptacle is placed therein. y f y A further object -of' the invention is the provision of a resilient-support. for the bottle to maintain the saine safe. against breakage due to vibration ortlielikefyg..

The invention consistssubstantiallyinthe construction, combination, location and relativey arrangementjofI parts, 1all 'as will be more ful-ly. hereinafter set. forth, as 'shown by the accompanying drawigsand finally pointed out in the'appended-claims.

A great majority of the people who own and operate automobiles also number among the members of their families atleast one infant which is still in its mothers, arms.

It is quite usual to provide such infants with food in the forni of warm milk from :i bottle having a rubber nipple attached thereto.

As is well'known, infants1 become hungry .circuit and destruction.

at such unusual times that it is not always convenient to provide warm milk with which to appease their veracity. Especially is this true when the motorist takes his family for a trip or outing of any considerable duration.

I have, therefore, in response to this crying need, conceived ofa convenient devicefor attachment to motor propelled vehicles, whereby a babys bottle may be safely cari ried either before heating or during its heat# ing on the dashboard or other convenient place in a vehicle without danger: of destructionorloss.

IVith these objects in View, I Willnowdescribe my invention For purposes of illustration only, I have shown an embodiment of .my invention mounted on dashboardl ofa vehicle, although I conceive that it may be mounted in any convenient placein thev,veliicle. The -casing 2 may be made'ofany suitable insulating material, as glass,.bakelite, fibre steel or other material, andl serves to protect the heating-andfsupporting coils 3 from short The case.2, especially wh'enit is of heat in@ sulating material, such as asbestos, or the like, also serves to confine the heat to the enclosed area thus accelerating the warming of the-bottleinserted in the space thereof. The upper ends 1of the coils 3 project through the, insulating .ring l0. andare joined together in series by'. short ,connections A. `*These coils Spass throughliolesiri ean insu- -v-lating ringand terminate in airinsulating block 6 to which they may be attached in any suitable manner The short -jumper wires 7 serve -to connect the coils A3 in series gat-their lower. ends. Bythismeans all the `coils 3 .are connected iii series with the cx- -ception oftwo 'free ends 8 and 9 which are yconnected toa suitable power source l1 and :switch l2 respectively, which switch is also connected t'o the power source l1 by lead 13.

The ring l0 is detachably Asecured to the ring 14 which is mounted on the dashboard Vor other1 support l.

It will be understood that the bottle or device which is to be warmed will be inserted through the opening 17 and will be resiliently supported by the coil springs 3. I of course wish it to be understood that I do not desire to be limited as to shape or size of thedevice,and it will therefore be apparent which due to their resilience, willv adapt themselves as to relative position in accordance with the contour of the bottle or container inserted therein. Furthermore, Ifdo not desire to be limited orrestricted as to the particularV construction orI circuit arrangement employed, as many modifications will readily suggest themselves to those skilled in the art without departing from the spirit and. scope of my invention as deiinedin the claims. For example, as shown in Fig. 6, instead of having the resilient supporting wires 3 in the form cfa conductor, their sole function may be to resiliently support the bottle or other container and the resistance element 3a may pass therethrough, in or out of contact therewith, as desired. It is preferable in. this instance to have' asupporting coil of suiiicient diameter tov aff ord relatively large movementwithout subjecting the conducting element. 3a to excessive strain.l v I Likewise, instead ofhaving'tlie resistance elementV connected' in'series, as in' the arrangement shown in Fig. 1, it may be connected in series parallel. where the ring 10, to which is securedonefend" ofthe coils 3 is formed of conducting materialwto which one lead Sis attach-ed; and the. other end sof the coils"V 'areconnected together and the otherlead 9 is attached thereto.

Instead of a switch' 12 mounted on the dashboard 1, I also contemplate mounting av switch comprising a spring'finger 15 and a contact piece 16, on the block 6 so thatwhen the bottle is slipped into place'throu'gh the opening 17 its weight will. automatically close the circuit between ngerl' and coiitact 16; Thisswitch will, of course, be connectedv in circuit in a'ffmanner similar to switch 12 but in place thereof.

It will be seen `from the foregoing that I have provided a simple, inexpensive' but nevertheless efficient device which maybe utilized either vas a part of the permanent equipment, or employed to attach thereto, at small expense and with very little effort as an .accessory thereto; and wl'ierei'n` a simple and safe device is provided2 for 'heating bottles or other containers. Of `col1rse,when heating glass bottles ordinarily employed for feeding small children, theglas'sbeing a non-conductor, would not cause a short circuit in the series connection wherein sus pension coils are used as the heating element. It however, insulation is desired, enamelled wire could be used. Itis also apparent that the current source for heating7 the heatlr'esistance elements may bedrawn from the'storage battery o-r mot'orgener'ator of the vehicle.
