MEANS FOR FIXING A WHEEI. ON A SHAFT.
Specification of Letters Patent.
Application filed November 5, 1915. SeriaINo. 59,781.
To all whom it may concern Be it known that I, ISAAC J. PHILLIPS, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in the Means for Fixing Wheels on Shafts, of which the following is a specification.
One of the objects of this invention is to provide an improved method for preventing a pulley or wheel from slipping upon its shaft, which consists in interposing a bushing between thebore of the wheel and the shaft, the bore of the bushing being provided with means for biting the shaft and the contact surface between the wheel and bushing being eccentric relatively to that of the shaft, so that the tendency of the pulley to rotate relatively to that of the bushing will be counteracted by the tendencyof the bushing to bite the shaft, and the tendency of the pulley to rotate relatively to the shaft will be counteracted by the wedging moment due to the eccentricity.
With the above and related objects in view, my invention comprises the hereinafter described means, illustrated in the accompanying drawings, and embraced within the scope of the appended claims.
In the said drawings :.-Figure 1 is a front elevation of a pulley which is shown to be fixed upon a shaft by an improved method and means which is the subject of my invention; Fig. 2 is a side elevation thereof, only a fragment of the wheel being shown diagrammatically; Figs. 8-7 illustrate a method for deriving an eccentric contact surface from a concentric contact surface; Fig. 8 represents the central portion of Fig. 1; Fig. 9 is a central section of Fig. 8; Fig. 10 is a plan view of half a lining and bushing in connection'with Fig. 9; Fig. 11 is a central section thereof; Figs. 12-14 illustrate a modification of the method illustrated in Figs. 3-7, and Fig. 15 illustrates the eccentricity of the contact surface when the parts derived by means of the method illustrated in Figs. 1244: are mounted invertedly upon a shaft.
Referring more ings for a detail description of my invention, referring to Figs. 1 and 2, 16 represents the rim of a split pulley or wheel, 17 represents its spider, 18 its hub, 19 represents the bolts joining the hub, rim, 21 represents a split lining, 22 represents the pins carried by the lining projected within recesses of the hub to hold the lining in alinement with the hub, 23 represielntfs a split bushing, and 24 represents the s a t. i
The split lining 21 and bushing 23, shown in Figs. '1 and 2, which may be either cast or machined, are derived as follows :An annular cylinder, as shown in Fig. 3, whose axis passes through the center 0, is split and reduced along the dot and dash lines. The reduced parts are then brought together along the dot and dash line shown in Fig. 5 and reduced by turning to the circumference indicated by the dot and dash curve whose center is at 0, the center of the lower portion of the bore being at 0 and that of the upper portion being at 0*. A cylinder concentric with the annular cylinder and of a diameter approximately equal to that of the said annular cylinder is similarly reduced along the dot and dash lines shown in F ig. 4. The reduced parts are then joined as shown in Fig. 6 and bored upon the center 0, the parts being respectively concentric with the corresponding parts of the lining. The parts are then assembled along the line of contact shown in Fig. 7 and reduced from said line of contact to the dot and dash lines. The lining formed along the above described lines, either from a casting or a forging, is provided with the pins 22 to aline the parts with the corresponding parts of the hub of the wheel and with the countersunk rivet holes 26 for riveting onto the hub, and each part of the bushing is provided with bits 27 and with threaded holes for the set screws 28 adapted to hold the parts of the bushing in proper alinement with the shaft 24 when the wheel is mounted and the hub tightened thereon.
The method for deriving th lining and bushing illustrated in Figs. 12-14 is a modi- Patent'edAug. 21, 1917.
particularly to the draw-.
20 the bolts joining the method in so far as any tendency of Y parts overlapping as shown.
herein before described they are derived from cylinders provided with eccentric bores, Fig. 12 representing the cylinderffrom which the lining is derived, the center of the cirfication of the cumference of the cylinder being at 0' and and Fig. 13 representfrom which the bushing is that of its bore at 0, ing the cylinder derived, 0 being concentric with inder and 0 being the center of said cylinder of the lining cylinder. Both cylinders are then split and reduced along the dot and dash lines shown in Fig. 1%, the lining cylinder being turned and the bushing cylinder rebored with 0 as a center and then reduced further in a manner similar to that illustrated in Figs. 57.
The lining formed along the lines of the hereinbefore described modified method is alined and riveted unto the hub of a wheel by inverting the respective parts of the lining, and the parts of the bushing are invertedly mounted upon the shaft. This is illustrated in Fig. 15, wherein 0 represents the common center of the shaft 2d, of the bore of the bushing 23 and of the cylindrical surface of the lining 21, the center of the line of contact between the the lining and bushing being at 0 and that of the upper parts being at 0 I From the above it will be readily understood that any tendency of the wheel shown.
from sudden overloads of aheavy fly-wheel, the. inverted parts of the lining 21 and bushing 23 may be preferable; Assuming that the wheel shown in Fig.1 is mounted in'the manner illustrated in Fig. 15, and the spaces therein shown properly filled in, then the wheel to turn upon the shaft 2d will tend to cause each part of the lining to be resisted by the opposite parts of the lining and bushing, on account of the Having thus described my invention, what I therefore claim is,
1. In combination, a shaft, a wheel adapted'to rotatewith the shaft, the bore of the wheel being provided with recesses, and a bushing interposed between the shaft and wheel, the surface of said bushing being provided with pins for the recesses of the wheel and the bore of the bushing being provided with recesses, and teeth mounted in said recesses adapted 2. The combination of a shaft, a wheel and with outwardly pro the bore of the lining cyl I the center of the bore. which is concentric with the circumference posed between the lower parts of the bushing 23 radially and cause it to c bers being in contact,

provided with rehaving acylindrical bore,
adapted to be cesses, a cylindrical bushing mounted on the shaft to carry the wheel, I
said bushing provided with inwardly projecting wedges adapted to bite the shaft, 'ecting pins adapted to enter the recesses of the wheel.
3. In combination, a shaft, a wheel surrounding the shaft, and a bushing intershaft and the wheel, said bushing having a cylindrical surface and a cylindrical bore, pins projecting outwardly of he bushing adapted to carry the wheel, and plugs projecting inwardly of the bushing adapted to bite the shaft. 7
4. In combination, a shaft, a wheel, a bushing mounted. on the shaft, plugs carried by said bushing adapted to bite the shaft, a second bushing within the bore of the wheel and providedwith pins adapted to carry thewheel, saidbushings having an eccentric contact surface adapted to prevent their relative movement.
5. The combination of a shaft, abushing 1 mounted on the shaft and a wheel mounted on the bushing, said wheel, bushing and shaft being concentric, said bushing comprising two members having an eccentric contact surface, one of the members being provided with projections adapted to carry the wheel, and the other member being also provided with projections adapted to bite the shaft.
6. A bushing adapted to be interposed between a shaft and a wheel,and comprising a member having a bore concentric with that of the shaft and provided with projections to bite the shaft, a member having a surface concentric with provided with projections to carry the wheel, said members being provided with an eccentric contact surface.
7. A bushing adapted to be interposed between a wheel and a shaft and comprising an annular inner member and annular outer member, the inner member beinggprovided with a cylindrical bore, the outer member being provided with a cylindrical surface that of the shaft'and concentric with that of the bore, said memthe contact surface between the members being eccentric relatively to that of the bushing, the inner member being provided with projections adaptshaft, and the outer member being also provided with projections adapted to carry the wheel.
