UNITED STATES PATENT OFFICE CHARLES V. FILLMORE, OF MARENGO, ILLINOIS.

VEHICLE-HUB.

SPECII'ICATION forming part of Letters Patent N0. 335,442, dated February 2, 1886.

Applicatiou filed Octobe1 19, 1885. Serial N0. 180,311.

T0 all whom it mag concern:

Be iE known El1aE I, CHARLES W. FILLMORE, a resident 0f Marengo, in Ehe eounty of Me- Henry and State of Illinois, have invented 0er- Eain newand useful Improvements inVehicle- Hubs; and I do hereby deelare Ehe following Eo be a full, clear, and exact deseription of Ehe invention, such as will enable others skilled in Ehe arE Eo which 1'E pertains Eo make and use Ehe same.

My invemion relates Eo improvements in vehiele-hubs, and is fully Set; fo1Eh end described in Ehis speeifieation, end shown in Ehe aceompanying drawings, in which- Fignre 1 is a plan of a hub embodying my invention; Fig. 2, a longitudinal cenEral see- Eion 0f one-half of Ehe hub; Fig. 3, a transverse seetion of one-half of Ehe hub Ehrough Ehe line w y, Fig. 1; Fig. 4, a similar secEion Ehrongh Ehe line m1, Fig. l; Fig. 5, a longi- EudinaleenEral secEion ot' a modified form of Ehe reEaining-bar, together wiEh Ehe eneireling bands in operative connecti'on therewith; Fig. 6, an elevation 0f parE of an encireling band of modified forn1.

In Figs. l, 2, 3, 4, A is a wooden hub of 01- dinary form, having in its middle portion a series 0f spoke-morlaises, C, and a corresponding series 0f Eenon-mortises, C, each of Ehe spoke-mortises being adapted Eo reeeive Ehe approximately full-sized end E of a spoke, end each Eenon-mortise to receive Ehe corresponding Eenon, E.

BeEween Ehe spoke-morEises, and forming Ehe side Walls Ehereof, are a series of metal retaining-bars, D D, whose ends extend beyond Ehe spoke-mortises Eoward boEh ends of Ehe hub, Ehe ends being embedded in Ehe wooden hub, and Eheir exposed faees being flush wiEh Ehe surfaee Ehereof. These bars are held in plane and firmly united wiEh Ehe wooden hub by Ew0 bands, B B, whieh eneircle Ehe hub 0n opposite sides of Ehe line of spoke-mortises,

anti COVI Ehe embedded ends 0f Ehe retain- (N0 model.)

form D is a EruneaEed wedge, iEs sides being aE such an angle EhaE Ehe side Walls of Ehe spoke-morEise are parallel, while Ehe form D is a wedge of such angle as t0 make eaeh spoke morEise narrowesE an Ehe surfa'ee 0f Ehe hub. IE is evidenE EhaE when bars of Ehe form D are used the spokes ean only be drawn from Ehe hub by firsEdisplacing Ehe bars, each spoke being thiekesE aE Ehe tenon-shoulder, and gradually decreasing in Ehiekness from EhaE point ouEward Eo Ehe snrfaee of Ehe hub. 111 Ehe use of eiEher form D D Ehe side faees of eaeh reEaining-bar are in cl0se eonEaeE wiEh Ehe Ewo spokes between whieh Ehe bar lies, so EhaE Ehere is n0 space beEween Ehe bar und either 0f Ehe spokes for Ehe admission 0f moisE- ure 01 Ehe lodgrnenE 0f maEter, which might tend Eo rot Ehe spoke. 'Ihere is, however, be- Eween each pair 0f cont-iguons spokes a 1*ecE angular depression equal in depth Eo Ehe Ehickness of Ehe bands B, and to fill Ehis depression and give Ehe bands B and Ehe retainingmetal betweeu Ehe spokes a uniform surface I have adopted Ew0 expedients, whieh are illusErated in Figs. 5 and 6, respectively.

Fig. 5 shows a rebainingbar having any desirecl erossseclsion, and provided with an inEegrally-fornned neutral plaEe, D, having a lengEh equal E0 Ehe length of Ehe spoke-mor- Eise, anda Ehiekness equalEo EhaE of Ehe bands B. In use Ehe side faces of the plaEe D (like Ehe remainder 0f Ehe side faees 0t' Ehe bar) lie in elose contacE wiEh Ehe spokes 011 eiEher side of Ehe bar, while Ehe end faces of Ehe plate are in conEaeE with Ehe inner edges of Ehe bands B, and make elose joints Eherewith.

Fig. 6 shows a band B provided WiEh in- Eegrally-formed plates B, of Ehe same Ehiekness es Ehe ring, and adapted Eo lie beEween Ehe spokes and cover Ehe reEaining-bars, Ehe Ewo rings B B and Ehe plaEe B B being of uniform surfaee. IE is evident EhaE eitherall Ehe plates may be forn1ed on one 0f Ehe rings B, or half 0f Ehe plates maybe formed 011 eaeh r1ng.

Fig. 6 also shows 0n Ehe margin 0f Ehe band a series 0f lugs o1 poinEs, B, adapted Eo enter Ehe edges 0f Ehe spokes and loek Ebern againsE longiEudinal movement. IE is evident EhaE Ehese may be used wiEh any of Ehe forms 0f reEaining-bars shown, end either wiEh or wiEhonE Ehe plaEes B, and I do noE limiE Ehe use of IOO this device to it's combination with the special forme of retainingbars shown.

The Patent N0. 324,928, f C. W. Fillmore, shows a hub provided with a series of retaining-bars, lying between the spoke-rnortises, and held in rigid conneetion With the hub by means 0f 'DWO retaining and eneireling bands, separated loy a consiclerable spaee fr0rn the ends 01 t-he spoke-mortises. The constrnetion shown in that; patent provided the edges 0f each spoke with a bearing wholly 0f w0od, thus insnring an elasticity which a 1netal bearing againsl: the edge 0f the spoke cannot give. In wheels of a certain dass and grade the elasticity thns secured is valuable and almost essential; bub the're are on the obher band a large dass 0f wheels in which elasticity is n0b desirable, hub strength, stiffness, and rigidity are the prineipal reqnirements. F0r wheels of t-he last-named dass, Ehe eonstrucbion shown herein (so far as the same consists in placing he eneircling bands B in eontact with rhe edges 0f thespokes) is preferable to th at show n in Ehe patent referred t0.

Patent N0. 324,927, 0f Charles WV. Fillmore, ShOWS a hub provided With a series 0f rebaining-bars sirnilarto those shown herein, though 11011 having he Same cross-sec'nion, said retaining-bars being encircled and held in p1ace by a Single band forn1ed with snitable spokeopenings. VVhile the construction shown in that patent is perfectl y practieal anal has various advantages whieh make il; valuable, ib is different fron1 the 0ne shown herein, 11011 only in various minor features whieh are sei; 01113 in the claimsof this applieation, hub also in the important particular that where two separate bands are used the ende 0f the hub may be slightly cone l 0r tapered, ancl Ehe bands forcecl on, and thns made much tighter than a Single band can possibly be.

In O. WV. Fillnxores Patent N0. 126,278 a hub is shown in whieh a series of retainingbars lie between the spokes, and are held in place by flangecl bands whieh encirele the hub and the ends 0f the retaining-bars, the flanges of Ehe bands being in contaeb with the edges 0t the spokes. The constrnet-ion sh0wn in bhab patent differs from that: sh0wn herein in many partieulars, bnlaespeeially in the fach that those part's 0fthe retaining-bars which lie between olne spokes are not in elose0ontaet therewit-h, bnu are separatecl therefrom by spaces snificient for the admission of moistnre and the lodgmens of extraneous matter. In lahis respect the constrnction shown herein is sbronger, neater, ancl better adapted to wibh- Stand deca-y.

Having now deseribed and explained my invention, what I claim as new, and desire 130 secnre by Letters Patenb, is-

l. The cornbination, with a wooden hub, 0f a series 0f spokes sei: therein, a series 0f metal. retainingbars lying between and in elose coutacb with seid spokes, and having' their ends embedded in the hub 0n opposite sides of the series ofspokes, and two metal bands eneireling the hub and nhe ends 0f bhe reaining-b2ir and in contaeb wibh the edges 0f ehe spokes.

2. 'lhe eornbinatioxi, with a wooden hub, 0f a series of s p0kes seb berein, a series 0f metal ret-aining-bars between ancl in elose eontact With said spokes, and having their ends embeclded in the hub on opposite sides of the series 0f spokes, two mebzil bands encircling the hub and the ends of the retaining-bars, and in contact With the edges 0f the spokes, and meal plates lying bet-ween the'spokes and superpos ed up0n bhe bare, and having a thiekness approximately tl1e same as thab of Ehe bands.

3. The combination, with the wooden hub A, the series of spol es sei; berein, and the bands B, encireling the hub and in eontaeb Wil;h the edges 0f Ehe spokes, of the series 0f retainingbars between and in elose eontact therewibh, and having their ends embeddecl in the hub wibhin the bands B, each of seid bars having an integrally-formed cenbral plabe, D", 0f the approxi nnate ohiekness 0f the bands B, substantially as shown and described, and f0r the purpose Set; forlsh.

4. 'lhe combinabion, with the hub A and the spokes Set therein and widesb ab the Lenonshoulder, 0f the retaining-bars D between 5 said spokes, and adapted to prevent; the Withdrawal'thereof fron1 ehe hub, ancl means, subsbanbially as shown and describecl, f0r holding said bare in eonnection with the hub.

In testimony where0f I have signed this 1 o speoification in the presence 0f w0 subscrib ing wicnesses.
