ENGINE-DRIVEN BLOWER FOR EXPLO$BON=ENGINES.
Specification of Letters Patent.
Patented Feb. 20, 1906.
Application filed an ry 11. 1905. $erial No. 240,570.
To all whom, it nuty concern:
Be it known that we, LEE A. FRAYER and VVILLIAM J. MILLER, citizens of the United States, residing at Columbus, in the county of Franklin, in the State of Ohio, have invented certain new and useful Improvements in Engine-Driven Blowers for Explosion-Engines, of which the following is a specification.
Our invention relates to improvements in engine-driven blowers wherein we provide a yielding gear-wheel mounted on the prime moving shaft and meshing with another gearwheel mounted on a secondary shaft, which carries the blower at its outer end. This arrangement relieves the blower from the shock due to the sudden starting or stopping of the engine, and inasmuch as the yielding gear is relatively larger than the gear with which it meshes the speed of the blower is thereby increased greatly beyond the speed of the engme.
Figure 1 shows a sectional view of our device and the manner of connecting the same to the main shaft. Fig. 2 is a plan view of the cog-wheel with one-half removed. Fig. 3 is an enlarged view of the cog-wheel in vertical section. Fig. 4 is aview of the removable middle portion of the cog-wheel.
In the drawings, 1 and 2 designate blades of the fan mounted upon the shaft 3, which carries upon its outer end a clutch 4, adapted to engage with a corresponding clutch 5 on the crank 6, used in starting the engine. Shaft 3 on its inner end carries a small cog- Wheel 7, adapted to mesh with the large cog-' wheel 8, mounted, preferably, upon the crank-shaft of the engine. Cog-wheel 8 is so constructed that it may be separated along the circumference, thus dividinginto similarly-constructed halves. Each half on-its interior side is provided with four projections or stops 9, 10, 11, and 12, each having an opening 13 therethrough. When the halves are placed together to form the complete cog-wheel, these openings register and bolts may be inserted therein. The cogwheel thus formed has a large opening 14 extending therethrough, into whichis fitted a circular art 15, provided on its circumferencewit four projections 16, 17, 18, and 19,
each of which is designed to be positioned between two of the stops above mentioned upon the inner face of each of the halves of the cog-wheel described above. Between the projections of this inner portion of the wheel and the stops spiral springs 20 are placed. This inner portion of the wheel contains an opening 21 to receive the crankshaft 22, to which it is keyed, as shown at 23.
Assume that it is now desired to start the engine. Crank 6 is applied to shaft 3 in the usual way and the motion induced in shaft 3 starts the fan, and by turning gear-wheel 7,
which meshes with the large wheel 8, the e11- gine is started. The power for operating the fan is then transmitted from the engine through the large gear-wheel 8, small gearwheel 7, and shaft 3. It is seen that the small gear-wheel will impart to the fan a higher rate of speed than that at which the crank-shaft moves. The relative speed may be regulated by varying the size of the small gear-wheel at the desire of the operator.
The inner portion of the cog-wheel 8 is rigidly mounted upon the crank-shaft, and therefore moves with it. The outer portion of said wheel has a movement independent of the inner portion, the limits of which are determined by the spiral springs and stops and projections. The range of movement is great enough to relieve the shaft 3, carrying the fan, from the severe shock incident to quick starting or stopping of the engine.
It is obvious that when the engine is quickly started or stopped there is more or less shock to be borne by the fan, and if the gear connection is rigid the shock is so great as to become a serious matter. We overcome this difficulty by the arrangement described above in connection with cogwheel 8, in which the springs between the projections on the inner wheel and the stops on the cog-wheel take up the shock to a great extent, and in this way the stress upon the fan is relieved. 1
