HEAT-EXHAUSTING DEVICE.
Application filed September 7, 1917.
To all whom. it may concern.'
Be it known that I, HENRI' SMITH, a citizen of the United States, residing at Cumberland, in the county of Allegany and State of Maryland, have invented new and y useful Improvements in Heat-Exhausting Devices, of which the following is a specifi cation.
.As a heat exhausting device, the invention seeks to provide, as its principal object, a compact and eii'ective means for extracting hot air from the crank-cases of internal combustion engines and the like, and replacing this with cool air. i
A further object is to provide a device of this kind which will be capable of exhausting hot air and admitting cool Iair to an engine crank-case in such la manner as to preclude danger of admitting dust or grit to the crank-case.
Cheapness of construction and simplicity of structure are other objects of the invention.
Still another object is to provide means in the device, whereby the crank case may be oiled therethrough.
Other and further objects will appear vas the detailed description progresses. A
While the invention is illustrated in but one of its embodiments, it is not to be considered as restricted to this embodiment. An actual reduction to practice may suggest certain desirable changes or alterations, which the right is claimed to make, in--so tar as they may be compatible with the spirit of the subjoined claims.
In the accompanying drawings z- Figure l is a side elevation of an internal combustion engine, such as is used with auto-vehicles. This figure shows the man ner in which the invention is applied to such an engine.
Fig. 2 is an end elevation of the structure shown in Fig. 1.
Fig. 3 is an enlarged View partly in elevation and partly in section o. the invention per se.
In the drawings, 14 is an internal conibustion engine provided with a crank case 2 and the invention is applied to this crank case by attachment in the hole through which the crank case is ordinarily oiled, as indicated at 8 in Fig. 1.
The invention itselt' comprises the nipple l which is threaded in the hole before re- Specication of Letters Patent.
Patented Oct. 1, 1918.
Serial No. 190,238.
fel-red to as existing in the crank casing 2. On the upper end of this nipple, there is threaded a coupling 5 which receives on its upper end, by threaded engagement therewith, a second nipple (i5. A tubularelbovv 7 projects from the side of the coupling 5 and its free leg is turned upward, receiving on its end the screw plug 8, which is designed as a closure member for the elbow.
rIhreaded ont-o the nipple (i at its upper end. there is a T U which receives in opposite ends ot its cross leg, by threaded en gagement therewith. the tube 10 and the bushing 11. The tube 12 projects centrallv through the bushing lll and is rigidlv fixed therein, this tube extending into the cross leg of the T 9 a sufficient distance to per mit it to cross the upper end ot the nipple (ln that end of the tube 12 which projects out of the bushing 11, a funnel 13 is attached, this funnel having a cylindrical hub portion 14 which effects a threaded engage ment with the end of the tube 12.
That end 15 of the tube 12 which is within the cross leg of the T 9 is truste-conical in shape, thus reducing the. diameter of the outlet ot' the. tube 12 at this end as compared with the inlet at the other end. Since the tube 12 is designed to take air at its larger end, this frusto-conical end 15 has the e'ect of creating a vortex at the outlet of the tube which results in a relatively greater suction being set up in the tube 10.
The invention is designed to be applied as shown in Fig. 1 and, as the engine shown therein is the kind commonly used on autovehicles, the invention is so positioned that, as the engine is moved'forward by the vehicle which it. drives, the funnel 13 gathers a quantity of cool air currents which are converged at the apex of the 'funnel and pass through the tube 12 at a high velocity, being further converged as they pass out the truste-conical .end 15 of the tube 12. As these air currents pass out of the tube 12 and through the tube 10, they serve to drive all the still air contained therein out of the latter, creating a partial vacuum which results in a suction through the air outlet from the crank casing 2` which air outlet is composed of the nipples 4 and't and their connecting coupling 5. Since the tube 12 enters the cross leg of the T 9 a suficient distance to extend across the upper end of the nipple 6, any dust or grit that may be gathered b y the tunnel 13 je driven out through the tube lO and thus prevented from dropping into the crank casiiig where it would likely do damage.
Since the device is attached vto the crank aeing in thc hole through which the .latter ie ordinarily oiled` the elbow 7 and plug 8 are provided for oiling the crank casing at the desired point, without disconnecting the device.
Ordinarily auto-\-'ehicles and the like employ internal combustion motors of the tourcycle type which, therefore, are not required to have gas-tight crank casings, as is the case with the two-cycle niotore. ln the eniployinent oi? the present inventioi'i7 it is pre ,sinned that the crank casing :an receive air through the infini-inge and beti'vcen the edges of its conn r`ting sections to t.: the place oi. the hot air rcinoved by tinl den ice L, y.nit in case this.: ineane of admitting ooi air ie not suiiicient, a hole may be termed in the trank Casing to adinit enough cool air to take the place of the hot air reinoved.
Without making any, provision, for the admission of cool air, it ie obvious that the device would be eHective in operation. The Cool air gathered by the funnel. ,i3 and discharged through the frusto-cmiical end will of course create sufficient suction to drive all hot air away frein the crank casing. Since. air is reduced in weight. as temperature rises. the heavier and cca-.ler air broucht through the tube 15 will drop doa the nipples G and i -ir c i thus tali-ing the place what is claimed l. ln a heat exhaueiinv dni-aw tor inter nal combustion engine rrauli-meiner and the like` an outlet tube, a T positioned on the top thereof, a .suction tuhc connected to one. end of the cross-leg' ot' the T. an inlet tubo projecting into .said cross-leg through the opposite end thereof, and a funnel attached to the end ot the inlet tuber` the inlet tube having the opening at its free end reduced as compared With the opening at its other end, whereby air currents may-be gathered by the funnel and converged. thereby and by the inlet tube to create a suction in and through the suction and outlet tubes.
2. In a heat exhausting` device for internal combustion engine crank-caeinge and the like, an outlet tube designed for attachment to the ciank-casix'igof an engine, said outlet tube having an elbow extending laterally therefrom 'which elbow provides a .rneans 'for oiling the crank-casing, a T positioned on the. top of the outlet tube7 a suction tube connected to one end of the cross-leg of the T, an inlet tube projecting into Said crossA leg through the opposite end thereof, and a l'unnel attached to the end of the inlet tube` the inlet tube ha ving the opening` at its, free end reduced as compared with the opening at its otheil end. whereby air currents may be gathered by the tunnel and converged thereby and by the inlet tube to create a suction in and through the suction and outlet tubes.
3. In av heat exhausting device for internal combustion engine crank-casings and the like, an outlet tube,y a T positioned on the top thereof, a suction tube connected t0 one end of the cross-leg ot' the T, an inlet tube projecting into said cross-leg through the opposite end thereof and extending' across the upper end of the outlet tube, and a funnel attached to the end of the inlet tribe; the inlet, tube h the opening at ite Atree end reduced as npa'red with the opening at its other end. whereby air currents may be gathered by the tunnel and converged thereby and by the. inlet tube to create a suction in and through the suction and outlet tubes.
In testimony whereof I affix my signature.
HENRY SMITH.
