Description

tirent iatza WILLIAM W. WEBB, OF INDIANAPOLIS, INDIANA.
Letters Patent No. 113,229, dated March 28,1871.
IMPROVEMENT IN BLCWERS.
The Schedule referred to in these Letters Patent and making part of the same.
I, WILLIAM W. WEBB', of Indianapolis, in the county of Marion and State of Indiana, have invented certain Improvements in Rotary Fan-Blowers, of which the following is a specification.
Nature and Objects of the Invention.
My invention consists in the construction, arrangement, and mode of operation ofthe rotary fan-blower, as will hereinafter more fully appear.
Description of the Accompanying Drawing.
Figure l is a side elevation of a rotary fan-b1ower embodying my invention.
Figure 2 is a side elevation of the same, with onehal' of the external case removed.
Figure 3 is a vertical transverse section of the same taken on line x x, iig. 1.
Figure 4 is a stretched-out view of the cam-groove formed by the pieces-T, in which the rolers O travel that give the required movement to the fan-blades F.
General Description.
A is the external case of the fan-blower, formed of twocircular pieces of metal or other suitableymaterial, that together constitute a circular tube, as shown, and which is made to it, at the inner circle of the tube, into a groove in a rotating ring, B, into which theinner edges of the case A is packed, so as to form the induction and eduction-orifices H and I, is lled` with any suitable material to form an abutment, J, leaving merely space between the filling in the halves for the blades F to -pass edgewise, as shown in g.- 2.
The shaft G, to which the fan-blades F are attached, have arms S near the hub G, in which the wheels O are pivoted, as shown, standing at an angle of forty-five degrees to the fan-blades.
In their rotary movement the wheels 0 travel in a cam-groove formed by the pieces T, which is shown in its stretched-out form in fig. 4, so arranged as to turn the fan-blades parallel to the plane of their rotation just as they pass the eduction orice I and enter the narrow space in the abutment J, and transversely, so as to ll or -close the circular tube as theyemerge from the abutment, s0 as to gather the air at the induction-tube H.
The direction of rotation is indicated by the arrow in fi 2.
Te position of all the fan-blades, when one of them is turned edgewise inpassing through the abutment J, is shown in g.'2.
The hub G is supported in position by spokes P, as shown in g. l, but not shown in the other guresA to avoid confusion.
The same device may be employed as a lift-andforce pump.
C' latins,
I claim as my invention- -l. The wheels O and arms S, attached to the fanblade shaft G, in combination with the cam-groove formed by the pieces T, arranged as and for the purpose set forth. v
2. The ring B, in which the hub C and fan-blade shaft G are arranged, in combination with the case A, substantially as set forth.`
WILLIAM W. WEBB.
