Specification of Letters Patent.

Patented June 16, 1914.

Application filed February 11, 1910. Serial N0. 543,323.

To all whom it may concern Be it known that I, FREDERICK G. PICK- ERING, a subject of the King of Great Britain, residing at New Glasgow, county of Pictou, in the Province of Nova Scotia, Canada, have invented certain new and useful Improvements in Wheels; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to vehicle wheels, and more particularly to means for adjusting the spokes.

1n order to more clearly disclose the construction, operation and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings, like reference characters designate the same parts.

ln the drawings Figure 1 is a side elevation of one half of a wheel, with the invention applied; Fig. 2 is a central cross section of a wheel, showing one form of the invention, applied; Fig. 3 is a side elevation of the outer sleeve; and Fig. 4C is a side elevation of one form of adjusting wedge.

The main object of the invention is to provide a simple and economical spoke tightening and spoke clamping device for the staggered spoke type of wheel.

A further and secondary object is that of providing a means for correcting the dish of one set of the spokes, independently of the other set of spokes.

Referring to the drawings in detail, 1 indicates an outside cylindrical sleeve provided with a central tapered flange 2, hav ing a plurality of bolt openings 3 extending therethrough at equal distances from its center. The flange 2 is adaptedto act as a separator for the alternate spokes 4 of the wheel. In order to hold these spokes in position on the sleeve and close against the flange 2, collars 5 and clamping bolts 6 are used. The bolts, of course, are passed through openings in the collars and spokes, as well as through the openings 3 in the flange 2. The openings in the spokes are slightly elongated as shown in Fig. 2 to permit slight relative vertical movement of the spokes on the bolts, for tightening the spokes and for correcting the dish of thewheel, all as will appear more clearly in the following de scription. A tapered annular wedging member 7 is carried by each collar and adapted to be drawn forcibly between the sleeve and spoke ends to exert a powerful, outward spreading movement of the spokes from the sleeve toward the rim of the wheel, to tighten the spokes. Preferably the member 7 is adjustable with relation to its collar, though this is by no means a necessity. The most desirable connection between the collar and the wedging member is a set of coopera-ting screw-threads on each. Each collar had a minimum diameter slightly greater than the maximum diameter of the sleeve 1. The inner diameter of the wcdging members 7 is just about equal to this maximum diameter, permitting the wedging member either to slide longitudinally on the sleeve 1, or to rotate thereon.

In assembling the wheel, the spokes will be arranged alternately on opposite sides of the flange 2 with the bolt openings alined with the bolt openings through the flange 2 and the collars 5 with their connected wedges 7 will then be slipped on the ends of the sleeve and moved toward flange 2 with their openings proper alined with the openings through the spokes and t-he flange; and clamping bolts 6 will then be passed through all of the alined openings. When the nuts are turned down tight on the threaded ends of the clamping bolts 6, the `two collars 5 will be drawn toward each other and toward the center flange. As the collars move in ward they will force the wedging members 7 between the sleeve 1 and the spoke ends. This will effect a powerful outward spreading movement of the spokes from the sleeve toward the rim or tire. The spreading action on both sides of the flange will be equal and simultaneous, of course.

During the use of the wheel it may be slightly dished on one side or t-he other. An adjustable connection such as that described, between each collar and its wedging member, may be used to counteract this. To this end, each of the wedging members is provided with sockets, notches or recesses 9 in its outer surface to receive the prong of a spanncr or like tool for giving the wedging member a rotary movement relatively to its collar. Due to the screw-thread connection between the collar and wedging member, the wedging member will either be drawn in by the collar or forced out by it, as it is turned by the spanner. In this way, it is possible to quickly and accurately counteract any dishing of the wheel on either side of the central flange 2. Likewise, adjustment on one side may be entirely independent of any adjustment on the other side.

The outer sleeve 1 is mounted on the inner sleeve 10, and is connected thereto by lugs 11 projecting from the sleeve 10 and fitting into cooperating notches 12 in the sleeve 1. Relative longitudinal movement of the sleeves in one direction is prevented by a collar 13 extending around the inner end of the sleeve 1, while like movement in the opposite direction is prevented by an overlapping nut 14 threaded on the project-ing end of the axle 15. 1Within the inner sleeve is mounted a roller bearing cage 16 adapted to contain a plurality of roller bearings, 17. A collar 18 is formed on the axle l5, and the roller bearing cage and sleeves 1 and 10 are all held in place on the aXle between this shoulder and the nut 14.

In order to prevent the entranceof dirt and other injurious substances, a dust cap 19 has been provided. This cap is provided with interior threads adapted to cooperate with the threaded portion 20 of the outer sleeve 1. In this way, the cap completely incloses the ends of the sleeves, the end of the roller bearing cage, and the overlapping nut.

It is thought that the operation and use tion, what I claim as new and desire to secure by Letters Patent, is

1. A wheel of the character described comprising a rim, a sleeve provided with a central flange, spokes connected at one end to said rim and having their opposite ends arranged alternately on opposite sides of said central flange, clamping collars movable on said sleeve longitudinally of the latter, means for drawing said collars simultaneously and by the same devices toward the central llange of said sleeve to clamp the ends of the spokes therebetween, wedging members slidably mounted directly on said sleeve beneath said spoke ends and moved to operative position by means of said collars.

2. A wheel of the character described comprising a rim, a sleeve provided with a central lange, spokes connected at one end to said rim and having their opposite ends arranged alternately on opposite sides of said central flange, clamping collars arranged on opposite sides of said central flange, wedging members carried by said collars and adapted to enter between said sleeve and the spoke ends, means for drawing said collars toward said central llangc to clamp the spoke ends therebetween and force said wedging members to operative position, and means for moving either ol. said wedging members relatively to its eollar and independently of the other oil said wedging members.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
