HEAD FOR RQTARY BLOWERS.
Specification of Letters Patent.
Patented Dec. 18, 1906.
To all whont it may concern:
Be it known that I, GEORGE C. HICKS, J r., a citizen of the United States, residing at Connersville, Fayette county, Indiana, have invented certain new and useful Improvements in I-Ieads for Rotary Blowers, of which the following is a specification.
This invention will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure 1 is a side elevation of a blowerhead embodying my invention; Fig. 2, an outer face elevation of the gear-case; Fig. 3, a vertical central section of the general structure; Fig. 4, an inner face elevation of the gear-case, and Fig. 5 an outer face elevation of the head with the gear-case removed.
In the drawings, 1 indicates the head-plate of a rotary blower of the ordinary type in which the axes of the two impeller-shafts are arranged in a common vertical plane; 2, the stufling-box glands for the shafts; 3, bearings for the shafts, the bearings being in alinen'ient with their appropriate glands and being supported by independent but integrally-formed brackets projecting outwardly from the head-plate; 4, semicircular ans constituting parts of the bearing-brac rets, these pans lying below the spaces between the glands and the inner ends of the bearings; 5, the pedestal portions of the bearings in rectangular trough form to receive the bed member of the bearings 6, the gear-case secured against the outer ends of the bearings and serving as a vertical tie and strut between them; 7, the base of the gear-case, the
same being in the form of an integrally formed pan; 8, one of the upper quarters of the gear-case resting upon t e base*portion; 9, the other upper quarter of the gear-case; 10, the flanged vertical joint connecting the two upper quarters of the gear-case, this joint coinciding with the common vertical axis of the two bearings; 11, the flanged horizontal joint connecting the bases of the two upper quarters of the gearcase with the base 7 12, bolts passing through the rear wall of the gear-case into the outer ends of the bearing-brackets and serving to secure the gearcase in position; 13, a pair of lugs projecting outwardly from the rear face of the gear-case and engaging downwardly over the outer end of the lower bearing-bracket, one at each side of the lower bearing, and 14 a similar lug engaging upwardly under the upper bearing-bracket.
The bearing-brackets give support to the gear-case, and the gear-case acts as a stay and strut for the bearing-brackets. Either of the upper quarters of the ear-case may be removed for inspection of t 1e gearing with out disturbing the other upper quarter or the base of the gear-case and without the necessity for removing any oil that may be in the base of the gear-case. In the construction of rotary blowers, as is well known, the impeller-shafts projecting from one end of the blower-casing terminate when they have received the gears at that end of the machine, while at the other end ofthe-machine one of the impeller-shafts terminates when it has received its gear at that end, while the other impeller-shaft I proceeds onward past the gear to receive connection with the driving power. The outer flat face of one of the gear-cases would accordingly be perforated to permit the onward passage of-the powerreceiving impeller-shaft. This construction is illustrated in the drawings.
I claim 4 1. A rotary blower-head comprising a headplate provided with a pair of outwardly-projecting separated bearing-brackets, a shaftbearing in the outer end of each of said brackets, an integrally-formed pan-shaped gearcase base secured against the ,outer face of one of the bearing-brackets and having a flat oint surface substantially in the plane of the axis of the bearing pertaining to the bracket to which it is attached, and a pair of quartercases'secured against the outer face of the other bearing-bracket and secured to the flat joint face of the base, and secured to each other by a joint substantially in the common plane of the axis of the two bearings, combined substantially as set forth.
2. A rotary blower-head comprising a headplate provided with a pair of outwardly-pro- I jecting separated bearing-brackets, a shaftbearing in the outer end of each of said brack-.
ets, an integrally-formed pan-shaped gearcase base secured againstthe outer face of one of the bearing-brackets and having a flat joint surface substantially in the planeof the aXis of the bearing pertaining to the bracket IOO to which it is attached, a pair of quartergaging between the outer ends of the bearcases secured against the outer face of the big-brackets, cornbined substantielly as set 10 other bearing-bracket and secured to the flat forth. j I joint face of the base, and secured to each GEORGE O. HICKS, JR.
other by a joint substantially in the comrnon plane of the axis of the two bearings, and Witnesses:
