Specification of Letters Patent.

Patented Jan. 1908-.
' To all whom it may concer-n.'
Be it known that I, Cir-ARLES K. PEVEY,
l a citizen of the United States, residing .at
IVorcester, in the'county of Worcester and State of lllassachusetts, have inventedeertain new and useful Improvements in Street- .Sweepers; and -I do hereby declare the following to be a full, clear, and exact description of the invention, such as will venable others skilled'in the art to which it appertains to make and use the same.v
My invention relates to improvements inv street sweeping machines, especially to that type of machine in which a `large rotary brush or broom is used to sweep the refuse.
- into a pan provided with a series of plates hinged to the edge thereof adjacent to tli'c broom. In short, my invention is an im-v provenient on the form of sweeper shown in the patent to E. S. Day, hid-.669,511 and dated March l2, 1'901.
In the use, of this patented sweeper, it has been found that the rigid metal plates hinged to therear edge of the pan` are often bent out of shape by coming incontact with a rock or irregularity in the road Awhen the machine is .backed without raising said plates, resulting from the carelessness of the driver, shying of thehorses, or other cause.
The object of my invention is to provide against the bending of said plates out of sha-pe onsuch occasions The invention cbnsists in constructing said plates 'of' flexible material which will give when it strikes an irregularity in -the road and will resume its place afterwards.l i The invention also consists in the features of construction and combinationsof parts hereinafter described and more particularly pointed out in the claims concluding this specification.
In the accompanying drawing illustrating the preferred embodiment of my invention:
YFigure 1 is al broken sectional. view transversely through the bromn, scraper, frame, conveyer, pan and one of the platesI hinged to said pan, of a machine constructed in accordance with my invention. Fig. 2 is a fragmentary detailed view illustrating metal plates with flexible edgings. Fig. 3 is an under plan view of onel ol' said plates, Fig.
. 4 is a detailed perspective view of a plate made entirely of flexible material, a portion of the pivoted rod around which it is mounted being shown as well as the metalslecve arranged around said rod and within theloop of the flexible material.' Figi is asimilar view of a modified construction of all flexible, plates in which double thickness is' -used.
xof Fig. 1v showing the arrangement and shape ofthe scraper for cleaning the lower conveyer-carry1ng roller, and F1g. 7 is a perinvention are illustrated in the accompanying drawings and their constructions'ian'd operations are described in this specification,
from the constructions shownv and-:described pended will permit. I
of said' pan extends to the conveyor-5,
of plates, each pivoted around a common rod, 7, provided withfingers, 8, extendin edge of the stationaryl portion of the pan, and'form a continuation thereot as shown, so that the dirt .is not allowed todrop out between them. A crank, 9, rigidly secured to said rod atene end is pivotally connected at the other end to the operating rod, 10, whcrc' by all the plates may be raised at'the same time and yet each may be thrown'upward independently ofthe others when it strikes a projection 1n the road. The main broom, 11, is .hung at the rear of thcv machine, as shown, and sweeps the dirtup over the hinged plates into the stationary portion of "the pan., The scraper frame, 12, which may be provided with any number of blades, 13, as may be desired, each o'f which is provided with an edging of wirebristles, 14, or of folded flexible fabric, 15, is arranged in front of the broom and above the stationary portion of the an.` its blades alternately engage the broom and the dirt on the bottom. of the pan, thereby serving the double purpose of cleaning the broom and passing the dirt forward to the conveyer.
I preferably make the plates entirely of rubber or some other suitable vllexibvlema.-
Fig. Gis a cross sectional view on the lineA spective view of 'said scraper '(let'acl1 ed.,', Vhile the preferred embodimentsvof Referrin morepartici'ilarlyD to the drawf ings, 1 is t ie stationary portionflof the pan which is provided'with side,flaxiges, 2 secured `by rivets, 3, or other suitable meanatothev body, 4, of the sweeper. The forii'a'rl edge As said frame is revolved,-
the right is reserved tofmake such 'changes 70 herein as the scope of the claims l1ereto,ap
while near its rear edge are hinged a series below each of said plates. 'The pivote( 'A plates are arrangedin juxtaposition to the '11o terial. lVhen` made rubber, asshown at 6 in Fig. 4, onlyfou'e thickness-is' used, and the forward edge is loo ed over the `rod, 7, andsecured by suitab e means such as the rivets, 7. 1
To insure the freeand easy movement of the plate upon the rod, a metal sleeve, 6a, is inserted within the folds or looped portion of the plate and iits loosely around said rod.
If thinner rubber GY is used to make the plates, it is folded at the center around the sleeve and the two thicknesses are held together by two or more transversev rows of rivets, as shown in Fig. 5. The u per or for-A ward portion of the plates may e stiifened and be iven greater rigidity by vulcanizing or by pacing a metalplate, 6b, below it, as shown in Fig. 5.
As shown in Figs. 1, 2' and 3, afurther modification of my invention consists in making the upper or forward ortion of the plates 6, of metal, 6c, to whicli is secured a flexible edging, 16, by means of rivets 17. In the latter form, the two end plates are preferably provided with side flanges, 18, which, with the flanges 2.0i the an, hold the bristles of the brush in p ace, preventing them rom spreading out, and keep the dirt from Working off the ends of said plates and`pan.
The scraper, 19, is preferably made of sheet metal bent to extend across the upper portion of the roller, 20, between the runs of conveyei' 5. The lower edge of the scraper plate 1s cut out on a curved line, 21, at each side of the central bend,22, so that it fits upon the curved surface of the roller. Said scraper is secured in position by rivets or bolts, 23, passing through ears, 24, on the ends of said scraper plate and the body, 4,
of the sweeper. It will be noted that the scraper, when in the position shown, is arranged out of the Way and does not interfere with the .free action of the conveyer while,
at the same time, it is placed at the point* where it accom lishes the best result.
Having thus escribed my invention, what I claim as new and desire to secure by Let- Y ters Patent is:
In a machine ofthe character described, the combination, with a stationary pan. and a broom of a series of iiexible plates independently hinged to a common rod and forming a continuation of said pan, `said rod having a ,series of fingers extending therefrom, one
below each otsaid plates, and means to.
