,LESLIE R. HUFF, OF PHILLIPSB'UR-G, NEW JERSEY, ASSIGNOR TO INGERSO'LL-RAND (lOMPANY, OF JERSEY CITY. NEW JERSEY, A CORPORATION OF NEW JERSEY.
OPEN IMPELLER.
Application filed July 5,
To all whom it may concern:
Be it known that I, LESLIE R. HUFF, a citizen of the United States, and a resident of Phillipsburg, county of Warren, and State of New Jersey, have invented a certain Open Impeller, of which the following is a specification accompanied by drawings.
This invention relates to blowers but more particularly to impellers for blowers of the 10 type in which the vanes or blades are opened or unshrouded.
One object of the invention is to secure the blades to the hub or shaft of the blower rigidly and securely in a simple and inex- 18 pensive manner.
Other, objects and advantages thereof will be in part obvious and in part pointed out in the following description in conjunction with the accompanying drawing in which,
Figure 1 is a longitudinal section of a blower in which the vanes are attached to the shaft in accordance with the practice of the invention,
Figure 2 is a cross section through the impeller blades and shaft along the line 2-2 looking in the direction of the arrows,
Figure 3 is a perspective view of one of the vanes before insertion of the shaft, and.
Figure 4 is a longitudinal section of a blower having a double suction impeller with blades secured to the shaft and to each other in accordance with the invention.
Referring toxthe drawings, the blower comprises a casing A of a'ny desired form, a shaft B extending through the casing having hubs O preferably formed integrally thereon to support impeller blades D. Each of the hubs G is provided with a plurality of grooves E which are preferably dovetailed in form and extend longitudinally with respect to the shaft B. Each of the blades D is formed with a. base F corresponding to the shape of the groove E.
In order to insert the base F of the blades into the dove-tailed groove E, the groove is cut in the arc of the circle and the base F of the blade is also constructed in the form of the arc of'a circle of the same radius as the groove E. The blade D is adapted to be attached to the hub C by inserting the base 1924. Serial No. 724,244.
into the groove E from the position shown in dotted lines in Figure 1 and rotating the blade to an upright position, generally perpendicular to the axis of the shaft B. With the blade in this position the ends of the groove E may be peened over to partly close the groove and prevent the blade from rotating. The circular shape of the base F stilfens the blade D and prevents looseness in the connection between the blade and the hub C.
In Figure 4 there is illustrated a modification in which the double suction impeller is provided with two sets of blades D inserted in the hubs G as in the modification shown in Figure 1. The slots are here cut in alignment with each other and opposite to each other on the hub C and may be held in the grooves E by means of a plate G riveted to each, but the slots may be staggered if desired. In order to remove the blades 1) from the grooves E, it is necessary to swing the blades in opposite directions, this being normally prevented by the plate Gr and also peening over the ends of the grooves E.
I claim:
1. A blower comprising a shaft, a hub on the shaft having a circular groove in a plane extending longitudinally with respect to the shaft, a blade, and a base for said blade insertable in said groove and adapted to be held in the hub thereby. 2. A blower comprising a shaft, a hub formed thereon having a circular dovetailed groove in a plane extending longitudinally with respect to the shaft, a blade and a circular dove-tailed base on said blade adapted to be inserted in said groove and held therein by peening the ends of said groove.
3. A blower comprising a shaft, a hub on said shaft having opposite circular dovetailed grooves in alignment with each other and extending longitudinally with respect to the shaft, oppositely disposed impeller blades, a dove-tailed base for each of said blades insertable in said grooves, and means for clamping said blades together whereby said blades are held against removal from said grooves.
for clamping said blades together whereby said blades are held against removal from said grooves.
In testimony whereof I have signed this specification.
LESLIE R. HUFF.
