I claim as my invention- 1. The combination, with a fan-casing having a discharge-spout and an annular eye enlarged adjacent the discharge-spout, of the fan-shaft extending through the casing and carrying fan-blades arranged to traverse the casing, and bearings for the shaft near each end thereof.

2. The combination, with a fan-casing having a discharge-spout and a central eye leading to said discharge-spout, of a central stationary core arranged in said eye, a shaft extending through said core, suitable bearings for said shaft, fan-arms, carried by the shaft, extending over the inner end of the core and downward into the fan-casing through the annular space remaining of the eye of the fancasing, and fan-blades secured to said arms.

3. The combination, with a fan-casing having a discharge-spout and an eye leading into its interior, said eye being substantially circular for its major portion and enlarged immediately adjacent the discharge-spout, of a fan-shaft, and the fan blades arranged to traverse the casing.

4. The combination, with a fan-casing having a discharge-spout and a central eye leading to said discharge spout and enlarged adjacent said spout, of a central stationary core arranged in said eye, a shaft extending through said core, suitable bearings for said shaft within the core, fan-arms, carried by the shaft, extending over the inner end of the core and downward into the fan casing through the annular space remaining of the eye of the fan-casing, and fan-blades secured to said arms.

5. The combination, with a fan-casinghaving a discharge-spout and an eye leading into its interior, of a fan-shaft, a central core surrounding said shaft and extending into the eye of the fan, and blades carried by the fanshaft to traverse the annular portion of the fancasing.

6. The combination, with a fan-casing having a discharge-spout and an eye leading into its interior, of a stationary core extending into said eye, a fan-shaft carrying blades arranged to traverse the annular remainder of the fan-casing, and bearings for the shaft Within the core. r

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 2d day of July, A. D. 1902.
