FLY-IWH EEL.
SPECIFICATION forming part of Letters Patent No. 402,564, dated May 7, 1889.
Application filed June 21, 1888.
To all whom it may concern;
Be it known that I, ROBERT B. COLLIER, of Columbus, Franklin county, State of Ohio, have invented a new and useful Improved Sectional Fly-Wheel, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to the construction of fly-wheels, and has for its object the construction of fly-wheels in two or more sections by means of devices which will, while enabling the ordinary advantages of s ectional construction to be obtained-to wit, stronger and better castings and greater ease in transportation'-in addition possess greater strength and rigidity, be moreperfecily true than ordinary sectional fly-wheels, and enable liners and shimming to be dispensed with.
Reference being now had to the drawings which illustrate myinvention, Figure 1 is a side elevation of my improved fly-wheel made in two sections, and Fig.2 a central cross-section thereof.
AA indicate the two sections of the wheel proper; B B, the sections of the central web, from which the spokes of the Wheel radiate, and which of course are sectioned the same way as the rest of the wheel. 0 is the hub proper of the wheel, made up, as shown, of a broad annular flange, C, and a sleeve, 0
D is an annular plate of dimensions corresponding to the flange O of hub O.
E E, &c.,are bolts provided with heads and nuts in the usual way.
F F are lugs perforated to receive a bolt, J, said lugs being formed, as shown, on the edges of adjoining sections of the wheel-rim.
Gindicates a wrought-iron ring shrunk into a recess formed in the casting between adjoining sections of the rim, and G G chipping-strips. Both of these devices, being usual in sectional fly-wheels,'need not be particularly described.
H is the crank-pin.
My fly-wheelis constructed and put together as follows: .Two sections,A'A are cast in the usual manner, the abutting ends of the castings being carefully planed and faced off both at the rim and at the central web, B B, so as to fit smoothly and truly against each other. The sides of the central sectional web,
Serial No- 277,769- (No model.)
B B, are also to be faced off, so as to be per fectly true, and the central hole the-rein carefully bored out to fit upon the sleeve (3 of the hub C. The annular flange G of the hub C a is faced off, so as to fit truly against one side of the sectional webB B, and the annular plate D is similarly faced to fit against the other side of the sectional web B B. A large number of bolt-holes are drilled through the flange O, sectional web B B, and the annular plate D, and carefully reamed to give a true and even bearing through all the three pieces for the bolts E, which should be turned to fit neatly in the hole. A perforation should also be formed to receive the crank-pin H, as shown in the drawings, the perforation passing through the flange C, the plate D, and one section of the sectional web B B, and being carefully reamed to fit the turn-pin H. The usualarrangement, such as indicated at F F, f, G, and G, may be used to secure the abutting edges of the rim together.
A wheel made in the above-described manner will be perfectly true and when put together as rigid as though made of a single casting. The sectional castings are stronger and more free from injurious strains than a single casting would be, and the wheel of course much more easily handled, as it can be loaded on the cars in sections and accurately and securely put together at the point where it is to be erected. It will be found desirable to shrink the hub 0 upon the shaft before shipment. This can be easily done without interfering with the convenience of transportation, as would be the case wherethe whole wheel was secured. to the shaft before shipment.
I have described and shown my improved fly-wheel as made in two sections. Three or even more sections could obviously be constructed in the same manner, and my invention would not be departed from by such a change. The number of sections into which the wheel would be divided is simply a matter of convenience in view of its size.
cable not only to fly-wheels, but also to the construction of unusually large gear-wheels,
asto which the same advantages would be gained by following my plan of construction.
Having now described my invention, what I It is obvious that my invention is appli- ICO claim as new, and desire to secure by Letters Patent,is
1. A sectional fly-Wheel consisting of a plurality of cast sections, A A, each comprising a portion of the rim and a corresponding portion of a sectional central Web, B B, the abutting edges of said sections being carefully faced off to fit against each other, and the sides of the sectional central Web being carefully and truly faced, a slotted hub, 0, made of a single flanging or casting, and having an annular flange, C, faced ofi to fit truly on one side of the sectional central web, B B, and having a sleeve, C turned to fit tlie central hole in Web B B, and an annular plate, D, made of a single piece of metal, turned and faced to fit on the sleeve 0 and against the sectional central web, B B and a num= ber of bolts, E E, arranged to fit in carefullyreamed perforations symmetrically arranged about the hub G and passing through: the central web,B B, andfiange O, the sectional the plate D. 1
2. Asectional fly-wheel consisting of a plurality of cast sections, A A, having a sectional central web, B B, the abutting edges of said sections being carefully faced off to fit against each other, and the sides of the sectional central web being carefully and truly faced, a hub, 0, having an annular flange, O, faced 01f to fit truly on one side of the sectional central web, B B, and having a sleeve, 0 turned to fit the central hole in B ROBERT B.
