'SPECIFICATION forming part of Letters Patent No. 616,205, dated December-20, 1898.
Application filed anuary 2 l, 18 9 7.
To @ZZ whom if; may concern.-
Be it known that I, GEORGE W. SHAMP, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements inVelocipedeBearings,of which the following is a specication.
This invention relates to the adjusting devices employed for taking up the wear of ballbearings, and more particularly to an adjusting device which is especially desirable for bicycle-bearings.
My invention has for its object to provide an adjusting device of simple construction which is easily accessible and which permits a ready and accurate adjustment of the bearing. In the accompanying drawings, Figure l is` a sectional elevation of a crank-shaft and hanger provided with my improvement. Fig. 2 is a cross-section in line 2 2, Fig. l. Fig; 3 is a detached fragmentary elevation of the shaft, showing the slot in the same. Fig. 4 is a sectional elevation of a crankshaft-and hanger, showing a modified construction of the adjusting means. Fig. 5 is a cross-section in line 5 5, Fig. Li. Fig. 6 is a sectional elevation of a wheel-hub provided with my improvement. 1
Like letters of reference refer to like parts in the several figures.
A is the hanger or bracket, which is of the usual cylindrical form and provided with the customary sockets or lugs for the attachment of the frarnetubes, which sockets are not shown inthe drawings. ln the construction shown in Figs. l and 2 the bearing-cups b are arranged to face inwardly and engage with the ends of the hanger screw-threads.
C .is the crank-shaft, C the cranks, and D the sprocket or driving wheel. One of the cranks is preferably integral with the shaft, and the other is kdetachably secured thereto by a key or other fastening, as shown.
e is the fixed' cone, secured tothe shaft opposite the right-hand .bearingcup, and f are the balls interposed between said cup and cone. This cone abuts against the shaft and is clamped against the same by a nut g; but thesame may be secured to the shaft by any other suitable means, if desired.
Serial No. 620,043. (No model.)
' 71. is the adjustable cone, arranged on theshaft opposite the left-hand bearing-cup, and i are the balls arranged between said cupau-d cone. The adjustable cone is arranged to slide on the shaft toward and from the opposing cup.
J is an adjusting-rod arranged axially in the shaft, which latter is hollow or bored out to receive the rod. This rod is free to move lengthwise in the bore of the shaft and operates upon the movable cone 7b through the medium of a ring or collar 7c, loosely surrounding the shaft and bearing against. the inner or rear verse pin l, passing through a longitudinal slot fm, formed diametrically inthe hollow portion of the shaft and having its ends se- 'cured to-the 4ring 7s. The front or inner end of the adj listing-rod bears loosely against the transverse pin Z, so that upon pushing the rod forwardly or farther into the shaft said pin and the ring lo are shifted in the same direction, thereby moving the adjustable cone t0- w`ard the opposing bearing-cup.
The bore of the shaft extends through the hub of the right-hand outer face of the same, terminates at a distance shaft, as shown in Fig. 1.
and the adj usting-rod from that end of the ln the outer porside of said cone, and a transcrank and opens at the tion of the bore not occupied by the adjusting-rod is arranged an adjusting-screw or screw-plug N, which engages with an internal screw-thread n of the bore and bears at its inner end against ing-rod, so that upon screwing the plug farther into the shaft the rod is shifted forwardly, or toward the opposite end of the shaft. The adj usting-screw N extends to the outer face of' the adjacent crank and is proi vided with a nick, as shown, for receiving a screw-driver, or, if preferred, its exposed end may be made dat-sided or otherwise formed to receive a suitable wrench for turning it.
When it is desired to take up the wear of the bearings, it is only necessary to screwthe plug N forwardly,'whereby the plug pushes the adj listing-rod J farther into the shaft, and the rod in turn shifts the sliding cone h toward the opposing bearing-cup through the intervention of the transverse pin Zand the ring 7c. The bearings, if too tight, 'are loosened by unscrewing the plug N more or less,
the outer end of the adjust- IOC i directly afraiiist an internal shoulder 7143 off` whereupon' the pressure of the balls against figure, A'
said cone will force the saine away from the opposing ball-cup unt-il the rod J limits the further movement of the cone by coming in contact with the screw-plug.
ingl screw or plug is accessible at the outer side As the adjustof thezuljacentcrank, the adjustment is easily and quickly effected.
lhe adjustable cone is confined against movement in one direction by the balls and in the other by the ring 7.','which forms a positive stop, and no lock-nut or other additional retaining device which must be separately maiiipulated therefore required for holding the cone iu place after adjustment, thus not only simplifying the construction of the adj usting device, but greatly facilitating the adj ustment ot' the bearings. `The sliding cone also affords a more accurate adjustment than can be obtained by the use of a cone which engages with the shaft by a screw-thread.
'.lhe ring 7.- may be made of soft metal, While the cones are hardened, as usual.
if desired, the adjusting-screw maybe formed in. one piece with ythe adjusting-rod; but the paris are preferal'ily separate, as shown, because by that construction the adjusting-rod not turned in adjusting the bearings, and the transverse pin is thereby relieved from the Wear which it would receive by the rotation of the adjusting-rod against it if the rod were made integral with the adjustin g-scre w.
ln Figs. i and 5 is shown a modified conl l l struction of my improvement which is applicable to bearings in which the cups face outi A provided with a bearing-cup, of a shaft ar- Wardly and the cones are arranged on the outer sides of the cups. The adjusting device l and a longitudinal slot intersecting,r its bore,
is in this case arranged at the saine end of the crank-shaft as the sliding cone ll". The boro of the shaft extends inwardly only a short distance beyond the sliding cone anda short adjusting-rod J' is employed, While the transverse pin passes through an opening formed diainetrically in the adjusting-rod and bears with its projecting' end portions the adjustable cone, so that when the rod is moved inwardly by the screw-plug N the pin carried thereby is caused to shift the cone toward the opposingbearing-cup.
My improved adjusting device is also applicable to the bearings of wheel-hubs, Fig. 6 showing a hub provided with the kind of adjusting device illustrated in Fig. l.
In this is the wheel-hub, having the usual perforated spoke-anges; C2, the bored axle of the wheel; h3, the adjustable cone; J 2, the adjusting-rod, and N2 the adjusting-screw. 'lhe bearings are in this case adjusted in the saine manner as in the construction previously described.
In the construction shown in Figs. l to 5 the crank-shaft hanger forms the inclosing ease of the bearings, while in the construetion shown in Fig. G the Wheel-hub forms the bearing-ease.
I claim as my invention-- l. The combination with an inelosing case provided with a bearing cup or surface, of a shaft passing through the ease and having a longitudinal bore and an opening extending from said bore to the surface o f the shaft, an adjustable bearing-cone arranged to slide lengthwise on said shaft, a pin for shifting said cone arranged loosely in the opening of the shaft, and an adjusting-screw arranged in the longitudinal bore of the shaft and operating to shift said pin in its opening, sub` stantially as set forti The combination with an inclosing case provided with a bearing-cup, of a shaft arranged in said ease and having a longitudinal slot extending therethrough, an adjustable bearing-cone arranged to slide length- Wise on said shaft, a transverse pin for shifting said cone arranged in the slot of the shaft, and an adjusting-screw arranged axially in the shaft and operating to shift said pin in the slot of the shaft, substantially as set forth.
2i. rlhe combination with an inclosing case ranged in said case and having an axial bore GEORGE XV. SIIAMP. YVitn esses CARL F. Gnrnn, ilvrnnrx Etalons.
