TURBINE-BLADE.
Application filed October 10, 1910.
To a]? whom 1'1 may concern:
Be itknown that I, CHARLES N. F. KNAPE, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have made a new and useful Invention in Tun bine-Blades, of which the following is a specification.
This invention relates to rotor motors and particularly to means for securing blades to the blade holding element of said motor.
The invention is illustrated as being employed in connection with a turbine of the impulse type in which there is an impulse disk or blade carrying element and blades secured to the periphery thereof by means of calking pieces or keys.
In the drawings: Figure l is a sectional view through a blade carrying element showing the blades secured thereto; Fig. 2 is an enlarged fragmentary view of a blade holding element, a blade and a calking piece inserted between the blade and its carrying element; Fig. 3 is a similar view showing the calking piece peened over after insertion; and Fig. at is a perspective view of one of the blades.
The blade carrying elementmay consist of a disk 5 on a shaft 6, said disk being provided with an annular dovetailed slot 7 having a straight face and an inclined face 9, said slot 7 being provided for the reception of the tail piece 10 of a blade 11 The tail piece and the blade are connected by a web 12 providing a slot 13 for the reception of a flange 14 on the periphery of the disk 5. The tail piece 10 is provided with a straight face 15 to rest against the face 8 of the disk 5 and the end of the tail piece 10 is provided with an inclined face 16 which approximately coincides with the angle of inclination of the face 9, said faces 9 and 16 being spaced apart. Within the space formed by the spaces 9 and 16 an insert or calking piece 17 may be interposed and driven home by any suitable tool, said calking piece 17 being of greater length than the depth of the face 16 so that the rojecting end of the calking piece may be ent over against the shoulder 19 of the tail piece Specification of Letters Patent.
Patented May 13, 1913.
Serial No. 586,288.
10 to form a lip, said calking piece being effective in securely wedgin the blade within the groove 7 of the disk 4). Any tendency of the blade to become loose by centrifugal force during the rotation of the disk 5 will be couutm'acted by the resistance of the face 8 to the face 15 and any sidewise movement of the blade will be resisted on the one hand by the disk 5 and on the other hand by the calking piece 17 so that after the two are secured together an efficient tight connection will be made.
Having thus described my invention, what I claim is:
1. The combination with an impulse wheel having an undercut groove and a projection and a blade having a slot and projection, the projection on the blade of less width than the width of the slot, the projection on the blade engaging the groove in the impulse wheel and a projection on the impulse wheel engaging the slot in the blade and fitting it, and means between the blade and the inner wall of the undercut portion of the groove for fastening saidblade and impulse wheel together.
2. The combination with an impulse wheel and a blade means for causing the blade and impulse wheel to interengage and a distortable wedge having a bent over end engaging a shoulder on the blade for securing them together.
3. The combination with an impulse wheel having a dove-tailed groove, a blade having a slot engaged by a portion of the impulse wheel which fills said slot, a tailpiece on the blade for engagement with the impulse wheel and a distortable wedge interposed between the tail piece and one edge of the groove and with the undercut portion of the groove, and having one end bent over a shoulder on the blade.
In testimony whereof, I have hereunto subscribed my name this 6th day of October, 1910.
CHARLES N. F. KNAPE.
