Specification of Letters Patent.
.iatented June 1o, 1913 Serial No. 736,662,
To a ic/ o'm '1 75 may (:0 21 (-6701 lie it known that Y, Lizs'run A. B11113, a citizen of the United t 'tates, and a resident of Cambridge, in the county of lvliddlesex and State of illassacltusetts, have invented a new and useful improvement in Electric Air-Il'eaters, of which the following is a specification.
My invention relates to electric air heaters and its object is to improve, simplify and cheapcn the construction of such heaters in the manner hereinafter set forth.
My invention will be described in con neetion with the drawingwhich accompanies and .forms a part of this specification, and which shows a longitudinal section of one embodiment of the same.
In the particular drawing selected for more fully disclosing my invention, 1 repre sents a well known type of c:.irbureter haw ing an air-intake pipe 2 to which my im proved heater is attached. in the present instance the flange i of the heater-tube is secured to the air-intake by the flanged nut 5, although it will be understood that any suitable means may be eniployed for this purpose. The heater-tube may shown be of liber or othersu-itabie insulating materiah or else of coi'iductino material, in which case the heating element must of course be insulated therefrom,
The healing elcu'lent is herein shown as a coil of wire 6 having its terminals connecled to the bii'iding posts 7, 7. llreferably the coil is cone'shaped, open at both ends, and tapering toward the air-intake. It forms a hollow, metallic, conical-shaped body and is so arranged that every particle of air which passes into the carburetor mustcome into contact with some portion of its radiating surface.
that, therefore, the air has a free and uninterrupted passage to the carbureter, as distinguished from similar devices in which the air must pass through restricted passages in order to reach the intake pipe.
It will be obvious that inyirnproved heat er may be Very cheaply constructed and eX- perience has shown that the energization thereof for fifteen seconds will enable the operator to start an automobile gasengine in the coldest weather as easily as in summelz Various modifications may be made in the heater which I have specifically described Without departing from the principle of my invention.
I claim:
An electric airdieater comprising cylindrical tube of uniform diameter tliroughout, and having unrestricted "open ends, said tube being adapted for attachment to an air intake pipe and forming a direct extension thereof, and an electric heating element com-- prising a wire coil freely supported inside of said tube, said coil being of conical shape, the large end thereof being substantially oi' the same diameter as said tube but out of contact with the Walls thereof, whereby a straight free air passage through salt tube is provided, and whereby the air currents throughout substantially the entire crosssection of said tube are brought into contact with the radiating surface of said coil,
in testimony whereof, i have hereunto subscribed my name this 11 dayof Dec. '19. 2.
