WILLIAM. M. TINNISWOOD, OF SANTA MARIA,- (JALIFORNIA.
BREATHEE FOR ENGINES.
Application filed April 27,
To or! whom it may concern:
Be it known that l, lVILLIAM M. TINNIS- woon, a subject of the King of Great Britsin, and resident of Santa Maria, in the county of Santa Barbara and State of California,'have invented certain new and useful Improvements in Breathers for Engines, of which the following is a specification.
This invention relates to breathers for internal combustion engines.
Briefly stated an important object of this invention is to provide an auxiliary air sup-- ply means for the crank case of an internal combustion engine and more particularly to the engine of the Ford automobile so that the internal pressure in the engine crank case is reduced to a minimunn A further object of this invention is to provide a breather which may be efliciently installed on engines either during manufacture or at any time thereafter without elaborately altering the construction of the same and without the exercise of unusual skill.
A further object of the invention is to provide a breather member for internal combustion engines which is of highly simplified construction, durable in use and cheap to manufacture.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawing, forming a part of this applicatlon and in which like numerals are employed to designate like parts,
Figure 1 is a side elevation of the improved breather applied.
Figure 2 is a longitudinal sectional view through the same, the sections of thebreathor being separated.
Figure 3 is a group perspective of the improved breather.
In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 generally designates an internal combustion engine having a crank case 6 upon which the cylinders 7 are mounted in the usual manner.
The invention forming the subject matter of this application is especially adapted for use on the engine used in the Ford automobile and it will be seen that a transmis-, sion 8 is arranged within the transmission housing 9 arranged at the rear end of the 1923. Serial No. 635,135.
crank case. The transmission housing 9 is" as illustrated in Figure lprovided with a detachable coversection 10 having. its upper side provided with an elongated opening 11 by the numerals '14, 15 and'16,the plate la being the outer section, the plate 15 being the intermediate section and the plate16' being the lower section. The several plates are securely and detachably joined by means of screw bolts 18 which are passed through aligned openings 120 in the plates and threaded into openings in the cover orupper half 10 of the transmission housing.
The air may circulate through a transverse opening-20 in the lower portion of the bot-. tom plate 16 and the air which passes through the opening 20 encounters a plurality of battle angle bars 24: secured in any suitable manner to the underside of the intermediate plate 15. If air is passing outwardly through the opening 20 it will encounter the bafiles 9A and any solid particles of oil suspended in the air will be collected by the ba'liles 24.
The oil thus collected by the baffles 24 will drip into the recessed bottom 26 of the lower plate 16 and will then return to the transmission housing by way of the transverse opening 20.
Figure 3 illustrates that the upper portion of the intermediate plate 15 is formed; with a transverse opening 28 for the passage of air after the oil has been removed there from. by the battles 24. The air which passes through the transverse opening 28 will contact with the raised portion 30 of the upper or top plate 14: and will then pass out through. a rather large opening 29 in the lower portion of the top plate.
Attention is directed to the fact that the oil is positively prevented from escaping from the transmission housing by way of the invention forming the subject matter of this application as the intermediate baflle member 15 is provided with reliable means by which the oil suspended in the air is re housing.
moved and returned to the transmission Therefore the exterior of the transmission housing is maintained more or less free from oil in the vicinity of the auxiliary breather.
through I the breather and thereby relieve the internal pressure in the crank case. Also the invention forming the subject matter of this application can'be applied to an engine either iduringtihe course of manufacture .or at anytime thereafter Without altering the engine in any way and without the exercise of unusual skill all of which contribute to the desirability and salability of the attachment. 7
It is to be understood that tl1B IEOI'Il'l of the invention herewith shown and described is to be taken as a preferred example of the same an'd that such minor changes in arrangement and construction of parts may be made as will remain within the spirit and scope of the invention as claimed.
Having thus described the invention,
what is claimed is I 1. An auxiliary breather for internal combustion eng nes comprising a cover plate I, adapted to be applied to the transmission housing provided with a chamber therein said cover being provided with openings forming respectively inlet andoutlet ports, a plate extending longitudinally .of the chamber and provided with-a pluralityof diagonally extending baflies by 'means of through the breather is removed.
2. An auxiliary breather for internal com bustion engines comprising a top, intermediate and bottom plate, means whereby the It will be seen that the air may circulate plates may be secured-together and across the opening of a transmission housing, the intermediate plate being provided on its under side with a plurality of diagonally extending angle bars constitutingbafiles by means of which the oil contained in the air is removed, the lower plate "b'eing provided with a recessed bottom for receiving said battles and .a transverse opening at its lower end for the passage of air and oil, the top plate being provided with .a raised portion defining a ;shallow chamber, theintermediate plate being provided with a transverse opening directly beneath the shallow cham{ ber anc communicating there-with.
3. In an article of manufacture, a com- .bined cover plate andbreather for internal combustion engines comprising, top, intermediate and lower plates, the intermediate plate being provided with diagonally extending angle bars constituting battles, for
collecting oil, the bottom plate being provided with a transverse air passage and a recessed bottom directly beneath said battles, the intermediate plate being also provided with a transverse opening for the passage of air and the top plate being provided with an opening communicating therewith.
