Description
A. TAUBER Sept. 29, 1925.
C OMMUTATQR Filed on. 11, 1923 Application filed Q'ctobcr 11, 1923.
To all whom it may concern.
Be it known that if, iln'rirun Tannnn, a citizen of the United States, residing at Yonkers, in the county of li estchester and State of New York, have invented certain new and useful improvements in Commuators, of which the following is a specification.
This invention relates to improvements in commutators and has for one of its objects the provision of mechanism for use in connection with commutators of internal combustion engines, for permitting the removal of the commutator from its usual position on the front end of the timing gear case be low the oil breather, as is the case in the well known Ford motor car, and for arranging the commutator in a place where it will be convenient for inspection and free from pollution from oil, grease, and the like.
With this object in View it is proposed to cast integrally with the motor or provide a detachable bracket to comprise a supporting member for supporting the commutator in I the desired location. It is also proposed to provide an excentrically driven member, se cured to and driven by the cam shaft of the motor, which carries a spring pressed brush, preferably of copper, which travels in a rotary motion over the face of a bakelite card provided with contact studs, so that the eXcentric travel of the brush contacting with the several studs regulates the appropriate timing of the cylinder firing.
With the foregoing and other objects in view the invention consists in the combination of parts and in the details of construc* tion hereinafter described and claimed, a specific embodiment being illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a portion of an internal combustion engine showing the commutator and its actuating mechanism, in vertical section, attached to the motor;
Figure 2 is a View in section taken along the line 22 of Figure 1, showing in detail the spring pressed brush contacting with the contact studs of the commutator;
Figure 3 is a view in section taken along line 33 of Figure 1 showing the sleeved guide pin in sliding relation with the guide rod;
Figure 4 is a view in section taken along line 4 of Fig. 1 the inner excentric member of the guide rod keyed to the front end of the cam. shaft of the motor.
Serial No. 667,9i.
Referring more particularly to the drawings a bracket 1 is attached to the timing gear case by means of bolts The upper portion of the bracket 1 terminates in an integral shell 2%. inside of which a collar 18 is rotatably mounted. The collar 18 is se cured to the bakelite card 3 of the commutator by means of screws a passing through the slots for limiting the rotation of the member 18 within the shell 2%. The commutator 3 is provided with contact stu s 1 A guide pin 8 is arranged on the bracket 1 and on this pin is slidably mounted an actuating or guide rod 5. An oil cup 9 is se cured to guide rod for lubricating through the oil groove 10. The guide pin may also be provided with a removable sleeve 26, while bolts 16 are provided in the guide rod 5 for taking up the wear on the sleeve.
Integral with the guide rod 5 is an outer collar 12 provided with a race with ball bearings 13 to form a bearing upon an inner collar which is mounted eXcentrically on and keyed to the front end of the cam shaft '27 by means of the key 23, washer 14 and nut 15.
The upper end of the guide rod 5 has screw-threaded therein a plunger sleeve 28 for carrying a spring pressed brush 6 with a spring 22 retained by the cotter 21 for forcing the brush 6 against the commutator card 3 and engage the contact studs 17 arranged therein.
The collar 18 is provided with 2. lug 19 to which is secured a suitable system of levers 20 for rotating the collar 18 and the card 3 for the purpose of adjusting the timing of cylinder firing.
The cam shaft 27 of the engine upon rotation, through the excentric members 11 and 12 causes a sliding motion of the guide rod on the guide pin 8 thus causing a rotary motion of the brush 6 over the face of the commutator card 3 in engaging the contact studs 17.
Thus it will be seen that I have provided a commutator which may be arranged in a location in which it will be convenient for inspection and removed from danger of pol lution from dirt and grease. There has also been provided an improved and novel means of actuation driven directly from the cam shaft of the engine.
I claim 1. In an internal combustion engine, a commutator, a Supporting member exte d ing upwardly from the timing gear case of said engine and provided at its upper extremity with a shell for receiving said commutator in rotary relation, a guide pin on said supporting member having. a rotatable sleeve mounted thereon, a guide rod carrying at its one end a spring pressed brush adapted to rotate over the face 071" said commutator and engage the contact studs thereof, an inner collar mounted excentrically on the cam shaft of said engine and keyedtosaid cam shaft, an outer collar integral with the other end of said guide rod and mounted on said inner collar, with ball bearings. therebetween, said guide. rod having a channeledportion slidably mounted on the sleeve of said guide pin, said channeled portion being provided w'th an oil cup and groove and a split portion beyond the channel, bolts extending through said split portion for varying the width of said. channel for the purpose of adjustment.
2. In an internal. combustion engine, a commutator, a supporting member extend ing, upwardly from the timing. gear case of said engine and provided at its upper extremity with a shell for receiving said commutator in rotary relation, a guide pin on said supporting member having a rotatable sleeve mounted thereon, a guide rod carrying at its one end a spring pressed brush adapted to rotate over the face of said commutator and engage the contact studs thereof, an inner collar mounted eccentrically on the cam shaft of said engine and keyed to said cam shaft, an outer collar integral with the other end of said guide rod mounted on said inner collar with ball bearings therebetween for the purpose of actuating said guide rod which integral with said outer collar, said guide rod having a channelled portion sli .lahly mounted on the sleeve 01'? said guide pin, said channelled portion being provided with an oil cup and groove and a split portion beyond the channel, belts extending through said split portion for varying the width of said channel for the purpose of adjustment, a system of levers for rotating said commutator contact studs with relation to spring pressed brush to accomplish the adjusting of the spark in said engine.
in testimony whereof I aflix my signature.
