SALYER REED EARLE, OF TORONTO, CANADA.

vCOMFOUND AIR-INSPIRATOR.

SPECIFICATION formingv part yof Letters Patent No. 685,117, dated October l22, 1901.

Application filed November 5, 1900. Serial No. 35,564. (No model.)

T0 @ZZ whom it may concern:

Be it known that I, SALYER REED EARLE, mechanical engineer, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Compound Air-Inspirators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this speciiication.

The present invention relates particularly to the compounding of air .injectors or exhausters; and it consists of a plurality of conical concentrations and enlargements or conical shells alternately arranged and successively decreasing in size and actuated by steam or compressed air discharged in the direction of the-greater concentration.

The invention consists alsov of a plurality of duplicating or compounding of air injectors or exhausters for the purpose of increasing the pressure and capacity of the machine as ablower or exhauster, and thereby increasing the usefulness ofthe steam or compressedair actuated blower without sacrificing the efiiciency.

To such ends my invention consists in the construction and the combination of parts, as hereinafter particularly described and claimed, reference being had to the accompanying drawings, forming part thereof, in which similar figures of reference refer to like parts throughout.

Figure lis a side elevation of a compound air-inspirator embodying my improvements, and consists of two sections discharging into a distributing-chalnber. Fig. 2 is a vertical sectionl of Fig. l and showing an elbow in place of the distributing-chamber. Fig. 3 is a top plan View of the conical concentrating portion of the sections. Fig. 4 is a bottom plan view of the conical enlarging portion of the sections. Fig. 5 is a plan View of the tubular ring and diametrically opposite radial branches and showing the arrangement of the nozzles. Fig. 6 is a cross-sectional view of a portion of the tubular ring. Fig. 7 is a Central sectional view of the nozzle; and Fig. 8 is an end elevation of the radial branches, showing the opening into which the supplypipe is secured.

To illustrate the present invention, it is shown as a duplex machine-that is, consisting of two sections, the upper and lower sections 1 and 2, respectively. A machine may consist of three or more sections when it is so desired to increase the pressure and capacity of the same .as a blower or exhauster. The sections are similar in construction and arranged consecutively with proportionally-decreasing areas and terminating in the flared portion 3. The object of gradually concentrating the moving air, in addition to the conical concentrations of each individual section, is to more fully absorb the kinetic energy of the liberated steam or compressed air as the air accelerates in motion.

The sections 1 and 2 are composed of two subsections each, the conical enlarging portion 4 and the conical concentrating portion 5 and having located at their greater diameter the tubular ring 6, which contains the nozzles 7. The .section and subsections 3 and 4 and 5, respectively, are connected by external annular flanges 8, bolted securely together and presenting an unbroken interior surface.

For the purpose of convenience in construction,and more especially in machines of large diameter, the conical concentrating portions or subsections 5 are composed of a number of vertical sections 9, preferably four, united by external ianges and bolts or by soltted lugs 9, as shown, for the purpose of more conveniently inserting the bolts or removing the sameA To control and operate the several sections collectively or individually,' a regulatingvalve l0 is inserted between the steam or compressed-air supply pipe 11 and the connections to the tubular ring 6 of each section. The tubular ring 6 is triangular in cross-section and supported by diametrically opposite radial branches 12, of similar cross-section, which enter a V-shaped recess 13, formed in IOO the ange 8 of the subsections 4. To fasten the tubular ring 6 to the subsection 4 and lie flush with the ange 8, provision is made for the reception of lugs 14, an integral part of the branches 1,2, and equal in width to the flange 8 and of suflcient length for the reception of machine screws or bolts. l

Provision is made in the tubular ring 6 for the reception of the conical nozzles 7, which are uniformly spaced and point in the direction of the greater conical concentration. f Pointing in the reverse direction is the apex of the triangular cross-section of the tubular ring and radial branches by which the resistance to the incoming air is greatly reduced, whereby the machine operates comparatively noiseless.

The machine operates with equal eciency in either a vertical or horizontal position. In the vertical form of adaptation it discharges into an elbow 15, provided with a supportingrest 16, as shown in Fig. 2.

When circumstances demand the supply of a number of air--conduits from one machine, either collectively or individually, (in the latter case it is obvious that cut-olf valves must be inserted,) a distributing-chamber 17 with, a number of outlets 18is employed, as shown in Fig. 1. The distributing-chamber may be attached to the reverse end of the machine when operating as an exhauster and accomplish similar results.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A compound air-inspirator comprising a body formed of a series of conical shells, alternately arranged with their greater diameters contiguous, and steam or air jets located in the spaces inclosed by the greater diameter, for the purpose hereinbefore set forth.

2. A compound air-inspirator comprising a body formed of a series of conical shells, successively decreasing in size and alternately arranged With their greater diameters contiguous, and having located in the spaces inclosed by the greater'diameters a plurality 0f steam or air jets, for the purpose hereinbefore set forth. K

3. A compound air-inspirator comprisinga number of independently-actuated sections consecutively arranged,each section containing a series of two conical subsections alternately arranged with their greater diameters contiguous,each section having located in the space inclosed by the greater diameter a plurality of steam or air jets, and means for communicativel y connecting the said sections to be operated collectively or individually, for the purpose hereinbefore set forth.

4. A compound air-inspirator comprising a number of independently-actuated sections consecutively arranged, each section containing a series of two conical subsections alternately arranged with their greater diameters contiguous, intervening rings supported by radial arms and carrying steam or air jets, and means for communicatively connecting the said rings to be operated collectively or individually, for the purpose hereinbefore set forth.

Signed at Toronto this 31st day of October, 1900.

SALYER REED EARLE.

In presence of H. DIXON, E. A. FoRsTER.
