Application June 4, 1945, Serial No. 597,548
1 Claim. 1
The invention relates to a motor and more particularly to an internal combustion rotary motor or engine.
The primary object of the invention is the provision of a motor or engine of this character wherein the rotor carries power blades, these being of the spider type and operate within a compression chamber interiorly of the casing and such blades are timed in their working so as to effect a continuous drive of the motor and smooth operation thereof.
Another object of the invention is the provision of a motor of this character which is compact and economically operated for the production of maximum power in the driving of mechanism.
A further object of the invention is the provision of a motor of this character which is most efilcient in operation, assuring maximum production of power and economy in fuel consumption, thoroughly reliable and efllcient in operation, and inexpensive to manufacture and install.
With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawings, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended.
In the accompanying drawings:
Figure l is a vertical sectional view through the motor constructed in accordance with the invention.
Figure 2 is a sectional view taken on the line 2-2 of Figure 1, looking in the direction oi. the arrows.
Figure 3 is a sectional view taken on the line 33 of Figure 2, looking in the direction of the arrows.
Figure 4 is a sectional view taken on the line 4-4 of Figure 2, looking in the direction of the arrows.
Figure 5 is a sectional view taken on the line 5-5 of Figure 4, looking in the direction of the arrows.
Similar reference characters indicate corresponding parts throughout the several views, in the drawings.
Referring to the drawings in detail, A designates generally the motor constructed in accordance with the invention and hereinafter fully described.
The motor A comprises a circular casing i0 having heads H and I2 respectively, while interiorly of this casing II is a rotor l3 forming an 2 annular chamber H which is separated into power, firing and exhaust zone l5 and compression and intake zone [6, respectively, by means of abutments l1 and I8, diametrically opposite each other and formed interiorly of the said casing.
The rotor is keyed to a power shaft I 9 journailed in center bearings in the heads ii and i2 for the casing Ill.
The casing III has formed therewith intake and exhaust leads 2i and 22 respectively opening into the power, firing and exhaust zone i5 and the compression and intake zone l6 of the said chamber H.
The rotor l3 at diametrically opposite points of the periphery thereof has fitted therein spider type bladed H 3, the blades of which are tripped by the abutm l1 and I8 and such vanes are fixed to rotatable supporting axles 2, these being journalled in bearings 25 fitting the rotor i3, Fixed within the casing l0 next to the head I2 is a timing ring 26 which coacts by means of notches 40 with trips 21 fixed to the axles 24 of the bladed vanes 23 and such trips 21 function in association with the ring 28 to have the blades of the vanes 23 override the abutments I! and I8 within the chamber ll at the correct times for the power operation of the motor.
Upon the casing I 0 is a combined firing and compression cylinder housing 28 having therein a rotatable combined firing and compression cylinder 29, it having the journalled ends 30 fitting the housing 28 and one of these journalled ends carries a toothed gear 3| meshing with a companion gear 32 operated from a timing spider wheel 33 suitably journalled and coacting with a timing ring. on the rotor l3. This combined firing and compression cylinder 29 has the cavities 35 therein and separated from one another while fitting the housing 28 is an ignition device such as a spark plug 36 adapted to be arranged within an ignition system for the firing of the charges within the cavities 35, that is to say one of the same when it is in communication with the power or firing zone I! through the port 31 provided in the abutment i8. This abutment it also has a port 33 which leads from the zone I6 when one of the cavities 35 in the cylinder 23 registers therewith so that the compression charge will pass through port 33.
It will be apparent that the power bladed vanes 23 are timed for rotation to clear the abutments I1 and i8 and also that the combined firing and compression cylinder 23 is timed for the explosion periods of the motor in the working thereof.
The gear 32 is journalled in the head I! and the timing ring 34 for the spider trip wheel 33 isdfiunted on the rotor l3, as will be clearly apparent from Figures 4 and 5 of the drawings. The spider arms of the wheels 21 and 33 have bearing rollers 39 and these engage trip notches l0 and 4| respectively in the timing rings hereinbefore described.
In the operation of the motor the rotor 13 is driven in one direction and through internal combustion action power and cycle of rotation thereof is efiected as should be obvious, while the timing for the explosion and the compression intake and exhaust periods of action is automatically controlled, in the manner as hereinbefore set forth.
For example, referring to Figure 1, each of the four cycles have been completed. The power or firing zone 15 comprises the cavity 35 in the cylinder 29 and extends downward to vanes 23, while the exhaust zone l5 comprises the exhaust lead 2| and the remainder of zone [5 to the vane 23. In like manner the intake zone 18 comprises the intake lead 22 and extends upward to the vane 23 while the compression zone 16 comprises the cavity 35 in the cylinder 29 and the remainder of the zone 16. Therefore, as the vanes 23 rotate past the abutments l1 and I8 the vanes will move into position for the cycles to be repeated.
It is believed that this description with Figure 1 as an example will clearly explain the operation of the motor without a more extended explanation. It will be understood, therefore, by those skilled in the art that a motor has been. provided that will accomplish the objects set forth and that changes and modifications of the various combinations and parts may be made within the spirit of the invention and the scope of the appended claim.
and intake zones ifi the chambers at opposite sides of the abutment said power firing and exhaust zone being to the left of the abutments, and said compression and intake zone being to the right of the abutments, a rotor within the casing and having spider type power bladed rotatable vanes adapted to be tripped by said abutments, intake and exhaust leads to and from the respective zones in said chambers, a timing ring fixed in said casing, tripping wheels for the said bladed vanes and controlled by said timing ring, a combined firing and compression cylinder fitted to the casing and having firing and compression cavities therein for communication with the compression zone, and the firing zone, a timing ring on the rotor, a trip operating said firing and compression cylinder and controlled by said last mentioned ring, and ignition means for the firing and compression cylinder.
