. STREET-SWEEPEB.

State of Missouri, have invented a new and Improved StrcetSweeper, of which the following is a full, clear, and exact description.

The invention-ibas in view the dproductionof a street sweeper carriedby an formino' a part of a motor, vehicle, referably of the autoinobile-'type,.and in w ich the sweeping mechanisin is driven from .the .vehicle motor.l

In the operation ofthe sweeper, the sweep- A ings are collected and delivered into the vehicle body, the latter being shiftable. on the ruiming gear of the machine to carry it to and from a dumping position'. 4 Provision is iliade for the sprinkling of the streetb the sweeper in advance of the brush, where y the dust is allnyed, and for'the .elevation of the. brush and connecting mechanism upon lthe vehicle vbody when itis tobe thrown out of action.

Reference is to. he had to the accompanying drawings forming a par-t ofI this specification, in which similar characters of reference indicate mrresponding parts inall the figures.

Figure 1 is u. plan of the sweeper complete' showing the ,brush and connecting mechanism in operative position; Fig. 2 is a side elevation oflho saine; Fig. 3 isa central, longitudinal section throughthe rear portion of the machine; F`0. 4-is a. section on the line 4 -4' of Fig2 looking rearwardly; Fi 5 is a section onthe line 5 5.of Fig. 2, loo g in the saine direction, and 6 is an' inverted plan of the forward portion of the machine, showing. a portionof'the mechanism for shiftin the Abody oftlie sweeper.

= he forward portion of the swee fr presents the same ap arance and is of t ie same general constructionas the ordinary ty'pe of automobile except that the power-transmise sion is slightly inodiiied to meet the special u requirements of this type of machine.. rI he rear portion-ot the'sweeper is co'i'isiderably increased'in width and carries a. box=body 10 movable oil-rollers 11, jonrnaled at opposite sides of the frame cfr-the running rear or chassis,.three rollc'i'sbei provii ei which are respixftively positionei la't,"t,lie rear of the drivers seat, at the rear 'ofA the machine and in an' intermediate position. The running gear also carries a tank l2 which is suspended underneath and extends the full length of the iiuwhiue.

As shown in F`..\'6`and in dotted outline in Fig'. l, a counters mit 13 is connected u i lwith `the motor in any suitable manner suc i that it may be controlled from the drivel-s seat in driving it in either direction or rendering it inactive. Fixed to the shaft 13 is ,a bevel )i'non lllshown inlzfighg, w l iich i sengaged y a beve-l pinion 15 secured to the lower end ,of an -inclincd shaft 16.

shaft carries at its` opposite and upper end a worin 17 in mesh with a worin-wheel 1S cariied by a shaft 19 whichis supported in suit able bearings and in turn carries a drinn 20. A cable 21 is wound intermediate itsilength about the drum 20 and has the opposite ends theieof iassing over sheaves 2 2 and 23, respective f arrai'iged and supported at the top and bottoni' anti slieave 23passe-s under the rollers 11 and is eoiuiected to the. bottom of thebodylO near its inner end. The o iposite end of the cable passes directly to an( is'coniiected with the miler end of said. body. i .-The drivi1i'f 'sl\aft of the engine, as shown lin dotted out ine in Fig. 1, isprovided with a bevel pinion 24 in me h with a similar pinion 25 attached to a cross shaft 2.6, the latter bein" extended beyond the machine at each side where it is )rovided with sprocketwheels 27, one. end of this sheit being also provided with a srocket-whe :l 21S arranged at the outside of the adjacent sprocket-wheel 27 and connected with 'a linger sprocketwheel 29 'by n chain 30 this last-nained sprocket-wheel heilig carried on the rear axle pro ielled.

ie sprmzketfwhiels 27, by cha-ins 31, are connected with and drive. sprocketfwheels 32 .idly mounted on studs near the rear axle and also in fixed ielation each with a' gear 33 in mesh with a gear 34, each gear 34 bein" journaled on a beariiw carried h v an L-s iaped arm 35, said arm being pivoted eccentric to the gear 34 at a point 36. The :irnis are slidf able within keepers 3,7 earned nl the sides ol' arni 35 is normally forced in :i re'nrv ardl direction by a spring 39 which operates to 'ecp This last-named at "he rear of the drivers. seat. The end of the cable passlng'over the of the sweeper through which the machine is the lbody l'U zuid areA instructed with hoiisl the gears 33 and 34 in mosh when the sweepingr mechanism is in operative position.

lilnshiingr with. the gear 34 at each side of the n'mchinc. is a gear 4() having:r a sprocketwhocl 41 in lixed rela-tion. therewith, which is connected with a similar sprocketfwheel 42 by a. chain 43. The sprocket-wheels 42 are fixed to the opposite reduced .ends'of a roller 44, which is jonrrrs-led in bearings carried at Ithe top center of' the body 10. A similar roller 45 is slidabloiin gnideways 46 fixed to the rear half of the" body 10, the gnideways 46 being slightlv depressed at their rear ends to retain the rol er'infoperative position when slid thereto.

'In mesh with the gears 40 at the oplosite vsides of the'mach'ine, 'are gears 47 connected with sprocketwhcels48 ori shafts which form theY )ivotal connection of arms or links 49, saidinks beingr in tu rn pivotally attached to links 50 and adapted to be retained in alinementtherewith b "loo is 51 slidable overthe adjacent ends o eaell pair of links` As shown in Fig. 1, the link 50 at the ri rht of the machine is offset to carry'it be on the hub of the rear wheel at this side o the sweeper, and tlns permits a' revoluble b rush 52 which is jou rnaled between the' free ends of the links 50, to' ass close ,to the curb`o the street when t e vsy'veeper is inaction. The axle of "the brush 5 2 is extended beyond the link .50- at the let of the' niachine and vcarriesv a sprocket-wheel 53 which is connected with and driven fror'nthe sprocket-wheel 48'by a chaini54.' As shown 1n detail in Fig." 5, the point of pivotal connection between the links 561 and 5 1v is provided with suitably-supported' rollers 5 5 which overhang and contact with the bottom and top links of tnechain 54.

Rigidl secured to the links 50 adjacent to the brus i 52;*isa pan 56 which is rovided with wheels 57 designed to travel) on the gnound and assist in supporting this part of the sweeping Jnwhanism when the machine is in operation. The construction of this Een as best shown in Fig. 3, comprises a an ed o'u'tpr edge '58"conformin'g to thebrus 52,- which 'prei-'ents the sweepingsfrom wasting out. after being collected. A rollef, 59 is joul'nalod crosswise of the al1-adjacentto the flange 5.5 and receives, t iereabont an elevator consisting of an apron 60 having buckets 61'. This elevator is provided with chains 62 at opliosite ed es adapted to zengage with sprocet-whees'63` secured to a" shaft 64 j ournal'ed near -the wren-dnt ther. fi

In the sides of the body 10. near-the topi front end thereof is journaled a cross shaft 65, having drums 66 fixed at opposite ends 443, thel line extending from this -point-.to the 7U adjacent link 50 to which it .is connected. By this construction, whenfthe brushand elevator are to hethrown out of action, by slidingr back the loops' lS'lffan'd winding up the line 68 by the 'operation' of thecrank 67, the 75 brush, pan and elevator are carriedby the cranks to an elevated ositi'on over the top of the bod f 10, the lin sf49 assuming a' vertical )osition withfthe links 50'atri'ght angles't creto resting'onfbrackets70at`tached 80 to the body 10, this inoperative position of the brush and connecting partsb'eing. shown in dotted outline in'Fl "12 land in full linesin Fig. 8.
