STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 542,571,.dated July 9, 1895.

Application filed November 2, 1894. $eria1 No. 527,712. (No model.)

To all whom it may concern:

Be it known that I, ANDREW JACKSON REY- NOLDS, a citizen of the United States, resid ing at Worcester, in the county of Worcester and State of Massachusetts,- have invented certain new and useful Improvements in Street- Sweepers, of which the following is a specification.

Myinvention relates to street-sweepers, and particularly to that class of sweepers provided with a receptacle into which the dirt is thrown as it is swept from the street.

The object of my invention is to improve upon the construction of street-sweepers of the class referred to as now ordinarily made, and to provide a street-sweeper of very simple construction and operation, in which there are two brushes arranged at an angle to each other and a receptacle at the rear of the brushes, into which the dirt, &c., is thrown by the brushes, the dirt being carried up and over the brushes into the receptacle by the revolution of the brushes, in connection with a curved angular deflector or apron in front of the brushes and in close proximity thereto, the lower part of said deflector being provided with a flexible portion adapted to drag upon the ground in front of the brushes.

My invention consists in certain novel 'features of construction and operation of my street-sweeper, as will be hereinafter fully described, and the nature thereof indicated by the claims. I

Referring to the drawings, Figure 1 is a plan view of a street-sweeper embodying my improvements with the front portion broken away and showing the brushes in section. Fig. 2 is a central longitudinal vertical section through the sweeper shown in Fig. 1.

In the accompanying drawings, 1 is the frame of the sweeper, consisting of two side bars and a rear bar. Extending forwardly from the frame 1 are two bars, which in this instance form the shafts of the sweeper. In the sides of the frame 1 the axle 3 is jour naled, and on the ends of said axle are mounted, to turn loosely thereon, the supporting-wheels 2 of the sweeper. The wheels 2 are adapted to be clutched inany ordinary way to the axle 3 to causesaid axle to turn --Fig. 2, and pivotally hung on pins 80, secured PATENT OEETQE.

with said wheels or to be unclutched to allow the wheels to turn without turning the axle, as is customary in this class of sweepers.

The receptacle 8, into which the dirt and sweepings are thrown directly from the rotary brushes, consists, preferably, of a metal bucket having a circular bottom, as shown in in the sides of the frame 1. v The bucket 8 is adapted to swing downwardly at its front end, which is next to the brushes, and upwardly at its rear end to discharge the contents of I the bucket in the rearof the brushes between the wheels of the sweeper. The-top of the front edge of the bucket does not extend as high as the side bars of the frame, as shown in Fig. 2. I have shown in this instance attached to the axle 3, and adapted to revolve therewith,- spring paddles or pushers 9, which as they revolve are adapted to strike against pins 10, extending up from the bottom of the receptacle 8, and pass by said pins and push the dirt from the front of the bucket into the 1 rear part thereof. In lieu of the paddles or pushers 9 any other suitable or equivalent deh vice may be employed for pushing the dirt as it is swept into the bucket 8 from the front part thereof into the rear-part thereof to prop;

erIy load the bucket. There are two rotary brushes 4 arranged w an angle to each other and directly in fro] 1-, I

of the bucket 8 and of the driving-wheels 2,

The brushes 4 are of sufficient length so t the outer ends thereof will extend beyond 11 9 wheels 2 and the inner ends at their frm; 3

portions will interinesh, as shown, in F a;

The brushes i are provided with central $1 I 5, which in this instance are supported 5 h i 1y outer ends by means of a supplementa, hi d frame 70, which in this instance is d't uy supported at its inner end on the o t d of-the axle 3 and extends aroundi f t of the brushes. The front portion of sa id f me 70, carrying the brushes 4, is in this f tg connected with the shafts by bars 71', h l d at one end to the shafts and pivotally at h d at their other ends by bolts 71 to the si i f the frame 70. (See Fig. 1.) 3 I provide levers pivotally supported on the front portion of the sweeper, as shown in Fig.

Tflexdeflector 71s secured by bolts or other:

2. The shorter lever 83 is connected through a spiral spring with the inner ends of the brushes, and the longer lever 85 is connected through a rod 86 with the outer end of one brush, and another similar lever (not shown) is connected with thevouter end of the other brush, so that the outer end'of either brush may be raised or lowered independently, and the inner ends of the brushes may be raised or lowered independently of the outer ends, as desired.

The rotary brushes 4 are each preferably made up of six separate sections or parts. arranged around the axles 5, each part being provided with a back 19 and bristles extending out therefrom, and each part attached separately to the central axle 5 of the brush,

in this instance by means of screw-threaded bolts 18, which are screwed into hubs onthe axles 5, and at their outer ends are provided with adjustable nuts, oneon the outside and one on the inside of the back 19. By turning said nuts in one direction or in theother each section of the brush may be adjustedoutwardly or inwardly, as desired. In practice, as the bristles wear down, the sections 19 are moved outwardly, as shown at the right in Fig. 1, to compensate for the wear of,the bristles. The inner ends of the axles 5 of the brushes are jointedly connected to a short shaft 6, carrying a sprocket-wheel 16 fast thereon and mounted in the outer end of anarm 17, Which is pivotally supported at its inner end onthe shaft 14. (See Fig. 1.) ,A sprocket-chain20 passes over said sprocket-wheel 16 and, over another sproeket-wheell5 fastonthe shaftlt, mounted in the lower front part'of theframe land provided atone end with a pinion.13, which meshes with a gear 12 fast on the axle.3. Itwillthus be seenthat as the sweeper is drawn along the revolution ofthe Wheels 2, clutched to the axle 3, will cause said axle 3 torevolve, and through gear 12, pinion 1.3, shaft -14, sprocket wheel 15, sprocket-chain 20,, and

g'sprocket-wheel 16 the brushes will-be*revolved. Arranged directly in front of the b rushes is a deflector or apron 7 which is of an gular shape in horizontal cross-section, as wn in Fig. 1, the angle of said deflector responding to the angle-of the brushes.

i to the front bar of the frame 70,0n which h b ushes are mounted. The deflector 7 is fcu ved shape invertical cross-section, as h n Fig. 2, and the upper part thereof t d irectly back over the top .of the brushes 1 oward the receiving-bucketS- The lower pa rt of the deflector ,7 is curved in- ,and is provided with a flexible porch is adapted to extend under the brushe h advantages of my improved streetsweegpel' will be readily appreciated bythose skiltled in the art. It is of very simplecon- 5 struction and operation, and the dirt, .as it is "swept from the street, is delivered directly brushes and the receiving-bucket.

from the brushes into the receiving-bucket, without the intervention of any intermediate mechanism, such as a fan, &c., between the WVhen the receiving-bucket is filled the contents are dumped in a pile by simply tipping the bucket on its pivot-support.

It will be understood that the details of construction of my street-sweeper may be Varied if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a street sweeper, the combination with a frame, an axle mounted thereon, two wheels loose on said axle, and adapted to be clutched ported directlyinfront of, andin close proximity to said brushes, said deflector of angular shape in: horizontal cross section, and of curved shape in verticalcross section, with its upper end extending back over the top of the1brushes,.and its lowerend provided with a flexible portion extending under thelower front part of the brushes, substantially as set forth.

.2. In a street sweeper, the combination with the frame, an axle mounted thereon, two wheels loose onsaid .axle, and adapted to be clutchedthereto to cause said axle to revolve with saidwheels, to operate, through interveningv mechanisimthe rotary brushes, and a collecting. bucket supported on the frame be tween the wheels, at the rear of the brushes, of two rotary brushes, located infrontof the collecting bucket, and extending at an angle to each other, and jointedat their inner ends, to a driven shaft and supported independently at their outer ends, and at their inner ends, sothat the outer ends, or .the inner ends may be raised or lowered independently,

and a deflector or apron supported in front of the rotary brushes, and in close proximity thereto, saidapron being of angular shape in horizontal cross section, and of curved shape in vertical crosssection, with its upper end extending rearwardly over the brushes, and its lower end provided with a flexible portion adapted to extend under the lower front part of the brushes, substantially asset forth. 7

3. In a street sweeper, the combination with the frame, andtwo rotary brushessupported thereon, and arranged at an angle to each other, and jointedly connected at their inner ends toa driven shaft, in such a manner that the bristles atthe inner ends will intermesh at their front portions, of an apron or deflector supported in front-of and in close proximity to the brushes, said deflector of angular shape in horizontal cross section, and of curved Witness my hand this 15th day of October, shape in vertical cross section, with its upper A.
