Specification of Letters Patent.
Patented Feb. 1, 1921.
Application filed September 18, 1919. Serial No. 324,671.
To all whom it may concern Be it known that I, JOHN E. SMITH, a citizen of the United States, residing at Moorestown, county of Burlington, .State of New Jersey, have invented certain new and useful Improvements in Heating Appliances for Internal-Combustion Motors; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to certain new and useful improvements in a carbureter temperature regulating device, and it has for its principal object to provide thermostatically controlled valve means for regulating the volume of air flowing into the carbureter whereby the greatest eflicacy and effectiveness will result from the combustible gas when ignited. within the engine.
The invention further resides in an improved air feed whereby both warm and cool air may be admitted singly or simultaneously and in a manner insuring greatest efficiency in the running and operation of the motor. I
More specifically, the invention resides in, what may be termed, a plural 01' compound valve, one section of which is designed to control the ingress of cool or cold air and another section or valve part to control the admission of warm or hot air, both valve sections or parts having a thermostatic control operable to actuate the sections in 1nverse or opposite order so that-as one closes the other will open.
The' invention will further be found to reside in the provision of awarm air chamber incasing one valve section to supply heated air thereto.
In the drawings.
Figure 1 is a fragmentary side elevation of an intake pipe system having the present improvements incorporated therein;
Fig. 2 is a similar view of a modified form of the invention in which the warm air valve is omitted;
Fig. 3 is a longitudinal section through the preferred form of the temperature controlling device of Fig. 1, per 86,
Fig. 4 is an end elevatlon thereof depicting more clearly the thermostatic control: and
Fig. 5 is a transverse section through the warm air end of the device, taken on line 5-5 of Fig. 3.
The warm air drum or casing 1 is prefer ably of cylindrical form and is-adapted for connectlon at the rear end with a suitable source of heat, not shown, as by a pipe 2, while within the forward end of the casing is set a ring 3 by screws 4 and whose inner face is circumferentially grooved, as at 5.
A valve-containing barrel or casing is divided into two sections or parts 6 and 7 having abutting peripheral flanges or collars 8 at their inner ends and diametral or spider bars 9 extending across their outer ends. The casing sections'have circumferential series of radial ports or slots 10 extending lengthwise thereof and the slots of one section are circumferentially staggered or ofi'set relative to those of the companion section in which relation they are fixed by the plIlS 11 uniting and passing throu h the flanges 8. Subsequent to securing t e sections together the composite casing flange 8 is engaged in the groove 5 of ring 3 which is split at 12 to facilitate such insertion when the ring is removed from the chamber and sprung apart. The ring is next positioned within the chamber and secured by screws 1.
Within .the valve casing is journaled a sleeve or tubular valve 13 by a pair of axially disposed screws 14. and 15 threaded through the cross bars 9 and formed with pointed ends engaging respectively, the solid inner end wall 16 of the valve and a diametral bar 17 in the outer end thus providing means for rotatably supporting the valve with minimum friction. The valve is formed with a series of slots 18 of suflicient length to pass over and register with the two series of slots in the valve casing, and, although when one casing series of slots is in full registry with the slots of the valve the other casing series is shut by the valve, stlll partial registry can be obtained concurrently between all the casing slots and the valve slots.
The outer cross bar 9 is formed integral with a removable ring 19 which is secured in the outer end of the valve casing by a plurality of screws 20 that pass radially therethrough and also secure a sleeve or coupling 21 to the end of the valve casing. This coupling is adapted to connect the air feeding device to the carbureter 22, the type of carbureter here depicted being the Zenith make.
Within the coupling is housed a ring 23 having a diametral support 24. for a coil 25' contract the coil and rotate the valve to dethe carbureter.
crease or increase the size of the warm air ports in valve part 6. To set the thermostatic coil so as to operate the valve to a greater or lesser degree or for different at mospheric temperatures, the ring 23 is rotatably mounted and carries a radial screw 29 operating in a slot 30 of coupling sleeve 21. A pointer 31 on the screw cooperates with the graduations '32 along one side of the slot and when the'desired setting is procured the binding nut 33 is moved downwardly to secure the ring fixed.
In the modified construction, the warm air chamber and valve part are omitted, the c lindrical valve casing 34 being connected irectly to'the heater pipe 2 and provided with air ports 35 adapted to be closed by valve 36 which is thermostatically controlled as in the preferred form.
It will therefore, be observed that the air is always delivered to the carbureter at a predetermined temperature. When the temperature of-the heated air is too great the expansion of the thermo coil will cause the valve to revolve in such manner as to cause its slots to coincide more or less with the slots in the outer drum or casing which will allow the outside air under the hood of the automobile to pass into the structure and thereby cool the air before it is delivered to If the air is insufl'iciently heated the set screw 29, 33 is adjusted downwardly in the slot which will cause the coil of thermo metal to be more tightly wound so that it will require greater expansive force to cause the inner valve to revolve to open communication with the air for cooling purposes, and therefore hot air from the heater will be confined within the structure without any cooling to speak of.
The stove or other heating agent that is employed is designed to always maintain a heat greater than the temperature desired for the air where it is introduced into the carbureter, so that there is no trouble in obtaining heat enough. As a matter of fact the temperature of the air delivered into the carbureter is lowered 15 or 20 by the act of mixing the air with the gasolene or other fuel, so that the temperature of the fuel mixture delivered within the engine cylinders would be too low if the thermo coil was not so adjusted that the air delivered to the carbureter would be heated 15 or 20 hotter. Therefore after the fuel is mixed with the air the resultant temperature is approximately correct for proper combustion.
In the summertime with an outside temperature of 92, that is to say, the temperature of the atmosphere, and in the instance of this particular car the engine runs best with the fuel mixture delivered at a temperature of and that 15 of heat are taken away by the act of mixing the fuel with the air, the temperature of the air at the point where itv is delivered into the carbureter should be Since 92 of this 100 will be furnished by the outside air it is only necessary to increase this temperature 8 the heater and this is readily provided for by the adjustment of the thermo coil which will cause the valve to operate to bring about this result.
For running in the winter when the temperature outside is zero it is necessar to employ a great amount of heat from the heater in order to get the zero air up to 100 by the time it is delivered into the carbureter, and therefore the thermo coil will operate in such a manner as to keep the slots in the inner valve part coinciding so as to get the full amount of heat into the interior of the structure and at the same time keep the outside slots in the outer valve part closed so as to kee J the heat in.
