SPECIFICATION forming part of Letters Patent N 0. 517,709, dated April 3, 1894.

' Application filed September 19, 1893. Serial No. 485,790- (No model.)

To all whom itmay concern;

Be it known that I, JAMES B. TILTON, a citizen of the United States, residing atFresno,

nia, have invented certa n new and useful I mprovements in Street-Sweepers, ofwhich the following isa specification, reference being to the The invention consists in the peculiar construction of a machine, especially designed for use in sweeping asphalt or other smooth to be pushed about by hand.

The invention particularly consists in the peculiar construction of the frame, the brush supporting, actuating and adjusting mechanism, and further in the peculiar construction, arrangement and combination of parts.

In the drawings, Figure 1 is a tion of my improved machine. plan view thereof. Fig. 3 is a tral, longitudinal sectionon the Fig. 4 is a'horizontal section Fig. 1.

A are the ground wheels connected by the drive axle B.

C are side bars of the frame supported on the axle and at their outer ends connected by the cross push bar 0', by means of which the machine may be pushed or pulled.

D are posts supported on the bars 0 over side eleva- Fig.2 is a top vertical, cenline y y Fig. on line x 00 of the axle, and connected together above the wheels, by means of the cross bar D.

About the middle of the side bars 0 are depending brackets E, provided with suitable caster wheels F which support the outer end of the frame. Inside of this truckframe and supported therefrom is the hood G which covers the semicircular dustv receptacle H which is pivotally suspended on the axle. This receptacle is provided with the circular heads or ends I which extend to near the hood G for a purpose hereinafter described.

Connected to the hood G is the inclined trunk L having a lip L engaging over the rear edge of the dust receptacle H, as shown in Fig. 3. The rear sideM ,of the dust receptacle is made slightly eccentric to the axle to permit of its engagement beneath this lip and still allow of the rotation of the receptacle same. The dumping accompanying drawings.

the various without friction with the lip in dumping the is effected by means of a strap N passing around the under side of the receptacle and through an aperture in the top of the hood, extending to the'front of the machine in convenient proximity bar. When the receptacle 1s a dumped moved the receptacle by being pivoted ecthe lower end of the trunk is hinged the brush hood 0. i

P is a rotary brush journaled in the rear ends of the arms P; which at their forward ends are journaled on shafts P secured to the side bars of the truck frame. The brush frame is supported by a rod Q connected at its upper end to the hand .lever Q, which is arranged in convenient its adjusted position by engagement with the notched segment Q is an inclined dust apron hinged at the lower end of the elevatortrunk and extendto carry the dust swept thereon into the pocket R at the foot of the elevator trunk.

' S is an elevator provided with suitable buckets and working through the trunk. The ele- On this stub shaft are sleeved two sprockets d e; the latter is connected by a sprocket chain f with the sprocket wheel 9 on the upper shaft of the elevator; the former is connected by a sprocket chain it with the sprocket wheel .t' on the end of the brush shaft.

provide drive mechanism for both ends of I the brush shaft according to the size of the pinions b on the stub shafts P nected or disconnected with wheels through the medium of may be conthe sprocket any suitable by the lever clutches T which are actuated U on the rear of the frame. connected to the clutches by means of connecting rods T and T U is a notched segment on the rear of the frame in which the lever U is adapted to engage to hold it in its adjusted position.

The apron the contracted portions-V and the trunk is provided with corresponding contracted portions V. This construction enables me. to use a wide brush and a comparatively narrow elevator giving me ample room between the hood and trunk and the sides of. the frame for the necessary drive mechanism, greatly lightening and cheapeningthe manufacture, besides simplifying the same.

W are flexible aprons hung from theends of the brushhhoodtopreventthe escape of the dust atthe-end and to direct. thedust upon the hinged, apron B.

By providing the: dust receptacle II with the the circular heads I on opposite ends, which thedust anddirt extend to-near'the hoodG,

afterleaving the trunk Lrcannot escape andv will fall directly into the dust receptacle What I; claim as my inventioniis 1. In astreet sweeper, thecombinationot' a wheeled truck,a dust receptacle pivotedion the axle thereof, and normally held with its mouth presented upward, means for dumping the receptacle, ahood covering the receptacle, an elevator trunk communicating with the hood above the receptacle, an in, an inclined hingedapron at the lower end of the trunk, a rotary brush at the lower end of the trunk, and drive mechanism for the brush and the elevator,substantially as described.

This lever U is R is provided on its ends witlr elevator there- 2. In a street sweeper, the combination with a wheeled truck and receptacle th ereon of the frame comprising a hood for the receptacle, an elevator trunk connecting into the hood above the receptacle and a brush hood hinged to the lower end of the trunk, the brush, the elevator actuating mechanism therefor, a lever on the truck, and a connection of the lever extending down and secured to the outer end .of the brush frame for elevating the same substantially as described.

3. In a street sweeper, the combination with a Wheeled truck, a frameonthe truck,a hood supported on the frame, a trunk, an elevator in the-trunk, a brush hood at the lower end ofthe trunk, a brush therein, means for actuating the brush and elevator, atdust receptacle eccentrically pivoted on the trunk, means for dumping said receptacle, the trunk for the receptacle either in-its normal-or dumped position, substantially as described. 4:. Ina street sweeper, the combination with 1 the frame, the hood, elevatortrunk and a semi circular receptacle pivoted unden the hood, having its rear portion formed eccentrically of a curved liplonthe upper edge of the lower face of the elevator trunkibeneath whichvthe eccentric portion of the receptacle is adapted to engage,and which acts as astop'for the edge oi' the receptacle when it is dumped, substantially asdescribed.

In testimony whereof Iaffix my signature in presence of two witnesses. JAMES B. TILTON.
