4To all whom/it may concern:

Belitkn'own that I, SIMONE-SMITH, of Stilem, in the county of Salem and State'of New Jersey, vhave invented anew and -nseful-Improvernent in the Tnrn-Bearin g or Fifth-Wheel of a Vehicle; and` l do hereby declare that the' followin g is a full, clear, and exaet description of the construction of' the seule, r.eference be:

ing 4had toltlie accompanying drawings, making a part'of thisspeciticatiomin vwiden- 1 'Figure-lisalongitudinal seetionof the said'- improvement applied to the axle and spring ofa light'carriage;Fig. 2,a plane viewofthe same as applied 5' Fig. 3,' a transverse section 'as connectedto theturn-bearing.

Like letters of reference indicate the same partswhen in the different {ign-res'.

` The object o f myimprov'ement is'to'affordv aneat, strong, 'and mncllle'ssfcostly turrrbearA ing or fifth-wheel foralight'carriage; '.and ny'invention consists .inconstrncting what is known as the head-block, t'getherwith -thev perch bearing or bearings and the'diskofthe wheel, in a single piece of cast metal, snbstani tially as hereinafter described and, also, 1in

combination with the sai'dtfth-wheel, thepeculiar construction and applicatOn f the kin g4' bolt, whereby the said wheel is secured'tc the scribed. I l

.Beferrin g to the drawings, A is the improved tnrn-bearin g B, the spring 5v 0.0, the perches D, thefront or oscillatory axle ot' thevehicle,l

and -AFr.theking-bolt which` connects the aille D and the-'turn-bearing At'ogether.v

The turn-bearing. A has; the lspring bearing- Fi g. 3,) and extending longitudinally acrossthe upperside of a', so as tc project ornament` elly at each end, in e.'

' old wooden heedfblock, (see Figs. l and 2,) and f also with the supports'd" 1t/"for the wooden grindingaway the opposite surfaces of the two disks a .and (1. f

manner similar'to the perches -C extendin obliquely in ai liorif zontal plane from a little above the seat of the spring B on the bearing a, so as to form abuttings-houlders a5 for the inner side .ofthe spring B,l to the length of a foot (more or less) beyond the edgeof the diskl a', as shown in Fig. '3. j 4The upper sideof each ottlie perclxbearings el" is sunk or groeved, so as to' receive the lower portion of thesuooden perch-Qandth usl "strengthen both. .'(See Fig.4.) L Y On the upper'sideo'fthe rear portion ofthe 'disk @dan adjust-able sliding clip,'a4, (se'e Figs. 2 and 3,)is`attacl1ed'by a screw'bolt, a", so that- `the 4said rear part of af'can vtherebybe coniined downnpon the projectingidisk-plate d whieliis.permanently .xed ontheaxlejI-end et the same-time allowthe said axle to be os,-

-cillated freely in a horizontal-'plane as herewhichv-thel'headof the bolt a5 is passed-ineppl-yiug or-rein'oving it, and the said plate 1d is alsofniade a' little concave-ou: its upper side,

andconsequ'ently allowsany sand or dirt to 'fall through the hole d, and thusjpreveuttbeir upon the bearing et', by means if two screwbolts, b' bf', the cap-plates ofthepercli'es being'. also secured rml ydown upon theirrespective' bearings fa" 'a" with the wooden-perches C' between. bymeans-of the additional bolts c c. A(See Figs. 2 and 3.)

The king-bolt E hasfalarger diameter along :its middleportion thenat its ends, for the pur-- pose of-'aft'ording the necessary strength and durability at 'the part around 'whichfthe axle E oscillates and the said boltisrigidlyed through-the partsA and B and secured bya screw-nut, as'sliown'in the Figs. 1 end 3.

TheA weight of this'my -improved turn-bear ing is not greater then'tbe weight of the usual mall'eebleiron f thwh'eel with yits supports,- 7, while the costof construction and application of' the former isA not more than one-half that of the latter,.and it-is equally durab1e, 'end much lessliable to get loose or otherwise out of order iu use.

1 wish it to be understood than do nos iutend to coniine myself in theconstructiou ofA my said improved turn-bearing to the use of" two perch-hars, C O, as it is obvious that the bearing Alcan be as readily made to receive a. single perch-bar in lits middle, if so required;

llordo I desire to claim, broadly, a turn-bearing or fifth-wheel' having its disk and perchbearings cast together in one piece of metal,

as this has'been done beforefor heavy'wagons but, What 4I claim 4as my invention,V and desire to secure by Letters Patent, is confined to the following, viz; Y A l 1Q The head-blockafgthe'peh-Beaping mi, and the disk a', when cast togetherin onepie'ce of .metal, substantially as, and for "the `purpose described.

2.In.combinatiou with the combined-.me-

chanical devices of theprecedng claimithe l.

king-holt E,'when constructed and appled'asr 'described and shown, for the purpose specified. f"
