SPOKE-SOCKET.

sPEcIi-"IcATIoN forming part of Letters Patent No. 339,721. dated April 1885- Applieatlon filed January 15, 1886. Serial No. 188,6.

To all whom, it may concern.-

Be it known that I, \VAUPER F. \VHITON, a citizen of the United States, residing at Bangor, in the county of lcnobscot and State of Maine, have invented a new and useful Spoke Socket and Tenon; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improved socket and tcuon for the spokes of vehicle-wheels, and is illustrated in the accompanying drawings, in which- Fignre .l. is an isometric view of spoke-socket turned upward. Fig. 13 is a front elevation of the form of bolt shown in Figs. 3 and 4. Fig. 3 is a sectional view through the center of the spoke, showing all the parts in position. Fig. 4 is a longitudinal sectional view showing all the parts in position. Fig. 5 is a sectional view 'of a second form of my device through the center of the spoke, showing all the parts in position. Fig. 6 is a front elevation of the form of bolt shown in Fig. 5. Fig. 7 is a sectional view of a third form of my de vice through the center of the spoke, showing all the parts in position. Fig. 8 is a front elevation of the form of bolt shown in Fig. 7.

Similar letters refer to corresponding parts throughout the several figures.

The object of my invention is to provide a device whereby the size of the mortises for the reception of the spokes in the felly of the wheel may be reduced to a minimum, the necessity of the shoulders commonly formed around such lnortises obviated, the tenons wholly omitted from the exterior ends'of the spokes, or, when not omitted, clasped, braced, and supported in such a manner as to prevent their wearing and rattling in their sockets, and thus, speaking generally, to produce a stronger and better wheel.

In the construction shown in Figs. 1, 2, 3, and 4, I provide a metallic socket, A, preferably of steel, consisting of the spoke-sockct proper, a, rim or plate a, and hub a, all being preferably formed integral. The part a is shaped to receive the tenon or point of the spoke S, and from and around its exterior surface, at or near its base, projects the rim or plate a, shaped to fit and bear upon the [No model.)

inner edge of the felly F and lap over its sides, if desired. The under side of the base of the socket a may be convexed, to conform to the curve of the inner edge of the folly, or may be slightly prolonged in its cylindrical shape below the bottom of the plate a, as shown in the figures above referred to. From the center of the under side of the base of the socket a, and in the direction of its longitudinal axis, is projected the hub c, of lesser diameter than the socket a, and preferably countersunk at its exterior end. The felly is correspondingly mortised to receive the hub u", and when the prolonged socket is used, to receive such prolongation also. The length of the hub a is not invariable; but I. prefer to construct it of a length somewhat less than half the thickness of the folly. I further provide a metallic bolt, ill, fitting the hub a, having a screwthreaded point, I), and a head, 1), preferably countersunk,) near the midlength of its stem, and when countersunk adapted to iit a corresponding countersink in the exterior end of the hub a.

In operation the spoke-socket A is litted upon the exterior-end of the spoke S, or when the end of the spoke is tenoncd, upon the tenon. The point I) of the bolt is introduced through the bore of the hub a and screwed into the spoke S, which is bored to receive it until the head I) of the bolt rests upon the exterior end of the hub. The end of the spoke is thus drawn tightly against the bottom of thesocket a, and the spoke S, spokesocket A, and bolt B are firmly held together, and the portion 1) of the bolt projecting above the bolt-head I) for1ns,esscntially,aienon to the spoke,or a continuationof the tcnon,il' the spoke be tenoned, the felly being mortised to receive the part b" of the bolt, and the hub u." (and also the prolongation of the socket proper, a, when such prolongation is used) is then littcd upon the part b of the bolt, which part is prefer ably formed of suliicient length just to fall short of reaching the outer surface of the fell y, althougl1,if desired, it may be made of somewhat lesser length, in which case the morliscs need not extend through the whole thickness of the felly.

The form shown in Figs. 5 and t differs from that before described simply in forming an internal screw throughcnlt the whole length of KOO the bore of the hub a, and a corresponding external screw,b",upon the stem of the bolt B, extending from immediately beneath the head I) for a distance substantially equal to the length ofthc bore ofthehub, omitting the screwthreading beyond the point thus reached and leaving the round point bof the boltsmooth. In this form the bolt B screws into the huba", as shown in Fig. 5. and not into the spoke, which is simply bored to receive the round point b" of the bolt. The bolt still serves as a teuon to the spoke or as a continuation of the tenon when the spokeis teuoned, but ceases to draw and hold the external end ofthe spoke to the bottom of the socket a. A substitute for this form may be produced by Formingthe bolt and socket integral; but I should not consider-it sodesirable as that l havedcseribed, as it would poss less strength.

The form shown in Figs. Tandtidillers from that first described simply in the substitution of a common serewbolt with common head, stenuand threaded point for the screw-bolt shown in Fig. 2. lhe spoke-socket used is that shown in Fig. l, and the application of this form is shown in Fig. 7, (the screw-bolt itself being represented in Fig. 8, l) the th readed point screwing into the spoke as in the first form, but the head of the screw,which is pro fez-ably ctmntersunk, bearing upon a corresponding countersink in the outer edge of the folly instead of the hub. the telly, substantially in the same way as by the form shown in Figs. 2; and l,w.ith the added advantage that when, owing to shrinkage or warping of the t'ellies,it becomes necessary to remove and reset the ti res of the wheel, a slight turning of the screw-bolts, together with the usual kcriing at the junctions of the ends of the fellics, leaves the wheel ready for the reception of the tire after it has been upset in the usual way.

3y means of my device I obviate the necessity of forming shoulders around the morlises of the telly, thus greatly simplifyingthc construction of the telly. I materially reduce the size otsuch niortiscs, this becoming possible by reason of the metallic bolt 13 being substituted for the wooden tenon of the spoke, as

whole operation of tcnoning the spoke, and I hold the spoke or spokc-tenon immovably in its socket, thus preventing rattling and wear from the constant jar and strain unavoidable in the use of wheeled vehicles, and I produce a stronger and neaterwheelthan those in common use.

I am aware that sockets for the spokes of wheels are not new, and therefore I do not claim a spoke-socket, broadly; nordo I elaim,broad- 1y, securing the spoke in the mortise of the folly by a scre\v-bolt,either with or without a spoke-socket; but

\Vhat I do claim, and desire to secure by Letters Patent, is-

1. In combination with the spoke and folly 01 a wheel, a spokcsockct having a rim or plate surrounding its outer periphery at or near its base, and a hub projecting from the under side of the base of the socket proper and in continuation thereof, and a bolt fitting said hub havingahead near the mid-length of its stem, and a screw-threaded point, so that the portion of the stem above the head may projectbcyond the exterior end of the hub when the parts are adjusted together and serve as a tcnon or a continuation of the tenon ot" the spoke. substantially as described.

.2. In combination with the spoke and telly of a wheel, a spoke-socket having a rim or plate surrounding its outer periphery at or near its base, and a hub projecting from the under side of the base of the socket proper and in continuation thereof, said hub having an Thespokc is held in internal screw-thrczuled bore, and a bolt fitting the bore of said hub and having a round point, a head near its mid-length, and an external screw-thread below such head for a distance substantially equal to the length of the bore of said hub and corresponding to the internal thread of the bore thereof, substantially as described.

3. In combination with the spoke and l'elly of a wheel, a spoke-socket having a rim or plate surrounding its outer periphery at or near its base, and a hub projecting from the under side of the base of the socket proper and in continuation thereof, and a bolt having a countersunk head, a screw-threaded point engaging with thcend of the spoke, and a smooth stem litting thebore of said hub, substantially as described. commonly used.) \Vhen desired, I save the \VALTER F. \VHITUN. \Vitncsses:
