To all'jwmmit may concern: Be it --kuown that I, JOHN CABLE, a citizenof the UnitedStates of America, and a resident of the city of Seattle, in thc county of King and State of lVashington, have invented certain new and useful Improvements in Svfeepingh'lachines, of which theI tions of parts, hereinafter' described and suc.

cinctly defined in my annexed claims.

Referring to the accompanying drawings in which like numerals of reference indicate like parts throughout: Al*`igure l isa top plan view of a sweeping machine constructed in accordance with my invention,'parts being broken away. Fig. 2 is .a side view thereof `with parts broken away. Fig. 3 is a cross sectional view. FigLelis fragmentary detail View,` illustrating more particularlyoiie of the slidably supported bearings for the drive shaft. Fig. 5 is a fragmentary view .showing more particularly the means for securing the fiights to rthe endless chains of thek conveyer, and Fig. 6 is a view 11i perspective ofl one of the blocks in which the axle of the Refer-rin to the drawings, 41 indicates a bottomless iousing provided at its forward end portion with an 4inclined a iron' 2, arranged to receive the sweepings rom a suitable brush 3, supported for rotation and driven by drive gears 4, fixed to the rear traction wheels 5, which latter are journaled on an axle 6, supported in any desired manner atthe rear end portion of the housing` as clearly shown in Figs. 1 and 2.

A snow considered, I4 provide gears 7 on the end portionsof thc axle 8` of brush 3.

the same being in mesh with drive gears 4 and being of a com aratively small diai'ncter.

To compensate or wearing of the brush, I support the saine for -vertical adjustment,

'mesh with gears 4.'

axle S beingjournaled. in blocks 9,'slidably.

arranged in curved slots 10, provided in the sidewalls of housing 1. i

Blocks 9 are pivotally connected with whereby during vertical adjustment of the brush, gears. 7 will not be Ythrown out of The' adjustment of brush 3 is etl'ectedby the operator who rocks a cross' shaft '11, journaled on an upwardly extending casing 12, through the medium of a lever 13,' having a latch .mechanism of ordinary form for engagement with the ,toothed segment 14.

Shaft- 11 is provided on its end portions with cranks 15, connected by links 16 with blocks l Reference numeral 17 indicates ariendless conveyerextending from 'apron 2 ina forward direction, then upwardly ina rearwardly curving path to the point of"discharge. By thisy arrangement of the conveyer the flights 18 thereof are caused to first drag over .the face' of apron 2 to gather the sweeping. Flights 18'have outwardly curved side edge portions 1S', Yand these prevent dis'- placeinent of the material duringthe rearward travel of the flights. The lower side edge portion 18" of each flight projects outwardly farther than the upper one' so asto engage and travetoverfthe inner face ofthe fori raid wall of casing 12.

now constructed, eonveyer 17 comprises two chains-A passing from sprocket wheels 19" on a drive shaft:v 19, over suitable idlcrs 20 and 21, the latterof which are car' ried-on a shaft 22, supported inside wings 23 of apron 2. Y

' To secure flights IS on saidendless chain,

T`provide certain of the links with lugs, `asl 2l (see Fig. 5) to which said'tlights are secured h v screws E25., i Y

Drive shaft. 19 is jonrn'aled in slidable bearings 26. connectedvitli adjusting devices 27, and is provided on one .end with a sprocket wheel 2S to Awhich iower is transmitted by a chain 29 from a rivcnushaft 3.0. Sliat" 30 is journaled on the top wall of 'housing 1 and provided with gears 31 meshing with drive gears 4,

Reference numeral 32 indicates a Vforwardly disposed shaftV driven by a chain 33 from shaft 30 and transmitting powerto 4suitable gearing 84, 34 to side brushes 35.

Brushes 35` are set in forwardly diverging planes so as to sweep on opposite vsides. o

12 I f wen-,ees

. frame o the machine and the axles of said.v brushes are connected by universal joints 38 pivotally support the same, as by hin es 45, A

the face of said apron, at all times.

."'in passing around sprocket wheels 19 discharge their contents through the discharge 'upwardly-as illustrated in Fig. 2, to an insame during such movement carrying with ceiver, thatshovvn beingin 'the form of aA as by hinges 18 on the housmor 1.

'handle 50 is 'provided on its end portions* the pathl of brush-3 and throw the swee l material tovtheiupper rear end thereof, the

ings'caught. therebyinto the pathl of said brush 3, as `wi l l be readily understood. Brushes 35 areV 'ournaled in frames 36 swingingly su porte on brackets 3 7 of the main with the' gearing 34, by which construction either or both of the brushes 35 can be swung operative position. As a means. for elevatV ing brushes 35 I have shownlinks 39 which are connected to frames 36 and to suitable levers 40 Brackets 37 are formed on the lower end portions of frame members 41 which are secured in any desired manner to housing 1 and casing 12 and extend forwardly therefrom to provideja platform 42 to which the forward axle 43,for the supporting wheels 44, is pivoted. l

To prevent injur to apron'Q, as by the same striking a roc or other obstruction, I

whereby the apron can swing vertical the it shaft 22 and thereby insuring of a proper action of the flights in their movement over In the operation of my machine, the flight opening -Got casing 12 into a suitable reclosed receptacle`47, swingingly supported A rock shaft 4 9, provided witha suitable operating with catches 51 which normally engage lugs 52 on the sides of receptacle 47 to prevent accidental swinging thereof.

If desired one or more fenders 53 'may be provided to prevent the housing or projecting .parts of the machine coming in contact with the curbing.

j'While I have herein shown and described a machine which will carry out the functions assigned toit, I reserve the right to make such changes in the details of construction as fall within the scope of my annexed claims.

Having thus described my invention what I claim as new, and desire to secure b v Letters Patent of. the United Statesof America, 1s:

1. In a street sweeper, the combination of a housing, sweeping means arranged in said housing, a casing communicating at it's front end with the housing and curving upwardly' an'd rearwardly therefrom, a conveyer arranged in said casing and adapted to carry I casing having a discharge opening at said upper 4rear end, supporting frame work for the aforesaid parts, areceptacle partially.

mounted in the space between the casing and the housing and provided in its upper portion with an opening into which material 1s discharged from the casing, and means for tilting the receptacle rearwardly from the .casing'to discharge the contents thereof.

'2. In a street sweeper, .the combination and a dirt rece tacle mounted pivotal y on said frame wort betweenits ends so as to tilt. rearwardly away from the 'curved cusing, said7 receptacle having its upper front portion curved so as to fit partly into the space between the housing andthe casing" and the curved portion havin "iii its top to receive material irom the discharge of the-casing. f

3. In a street sweeper, the combination of a supporting frame work mounted on wheels, a bottomless housin 'at the rear portion of said support. a brus 1 mounted in the housing, an apron at the front portion of the housing and in advance of the brush, an upwardly and rearwardly curving casing mounted. on the housing and communicatin atI its lower end with the front portion o the housing and above the apron aforesaid, a conveyor mounted in the casing, said casing having a discharge at its upperV rear end, a receptacle havin the frontbody portion thereof received tween the curved casing and the housin and being pivoted between its ends and t e'frame work so asto tilt rearwardly away from the casing, the upper portion of the receptacle being curved to conform with the curvature of the cas? ing and having an opening theremjust be low the discharge of the casing, locking de vices' for 'preventing .earward tilting movement ofthe ,/receptac1e, and mechanism mounted on the'casin; and connected wit the brush to raise and o Signed at Seattle, Washington this 17th day'of' December 1908.
