Serial No. 781L141.

To all whom it may concern Be it known that I, .lVILL'n-uu H. Donor, citizen of the United States, residing at Manhattan, in the county of Riley and State of Kansas, have invented new and useful Improvements in Street-Cleaning Iilachincs of which the following is o specification.

My present invention pertains to machines for cleaning asahalt and other hard and smooth roadways.

' The general object of the invention, is the provision of a machine of the character stated that is simple and inexpensive in construction, cllicient in operation. and is adapl; ed to be expeditiously and easily adjusted to take up wear as well as to enable the ma chine to operate to advantage under ditl'erent conditions.

The invention in all of its details will be.

20 fully understood from the following description and claims when the some are read in connection with the drawings, accompanying and forming part of this specificw ,tion, in which: v i

Figure 1 is a side elevation of the machine constituting the best practical embodiment of my invention that}. have as yet devised. Fig. 2 is a longitudinal vertical section of the machine. -Fig. 3 is a horizontal section of the machine, taken in a plane above the ronnd wheels from which I prefer to take motion to drive the elevator. igi 4 is a detoil. plan of a modified gather n hereinailtter specifically referred to.

Referring by numeral to the said drawings and more particularly to Figs. 1 to 3 thereof: 1 is the body of my novel machine which may be of any configuration cornpatible with the .function of the machine without ulfeetin my invention. The said body is provide at'fl with receptacle for dirt and other substance when up from a roudway; and thereeeptacl'z: is provided at El, ll igs. land with a hinge door to far cilitete reo'urval of the collected dirt and oi er suhstanye therefrom. The door 3 may obviously be normally secured in closed nosirion by'any conventional niez'ms. Fixe in "iihe body 1 and extending downwardly and :lorwardly from the upper portion of the forward wall of the receptacle 2 is an inclined well i which terminates or. its forward end in a forwardly directed portion. that extends to o. point closely adjacent the rivay or surface on; which the machine is rested.

As will be observed by reference to Fig. 2 the body is provided with side walls 6 that extend upwardly from the inclined wall l with a view to preventing the lateral escapoof dirt and other substance incidental to the raising thereof, as hereinafter described. Journoled in suitable bearings in the lower portion of the body 1 is a trunsvci" shaft 'T, and fixed on. the said shaft are ground wheels 8. Also fixed on the shaft 7 is a sprocket gear}. Suitably mounted in the body ribove the inclined wall and between the side walls 6 are drums 9 and 10, and passed around or arranged on the said drums is an endless blades 1.2. The said blades serve to move before them dirt and other substance from the platform or wall portions upwardly on and other substance in the receptacle 2. The

on the upward and rearward traverse of the same. The endless apron 11 is driven from one of the ground wheels 8 through the medium of a driving connection which preferably comprises a sprocket. gear 13 fixed with respect tothe drum l0 and a sprocket belt 14: mounted on and connecting the gears 9 and 13, as clearly shown in Fig. 1. At this point l'w'ould have it understood that the illustrated embodiment or my invention is designed to he pushed by 'a laborer or drawn by draft animals, and that in said embodi menl; I prefer as described to drive the endless apron 11 from one of the ground-wheels 8 v I would also have it uiulerstood that when my invention is uuriiuporated in a motor driven machine, as well as in a horsedrawn machine, the endless apron 1.]. may be without involving departure from the scope of my claimed invention.

By reference to Fig; .3 it will belobserved that the'transverse shaft. 7 is provided with two cranks 15 and a third crank 16, the latter being arranged intermediate of the cranks Connected to and extending for wardly from 'tho cranks 15 are rods 17, and. carried at the forward ones; of the said rods and between the said ends arranged transversely of the machine at the forward end thereof. The said scraper 18, as its name imports, is designed to scrape 01' rake dirt and other submachine is moved and assure the placing of apron ll having at intervals of its length the inclined walls l and deposit the said dirt driven by a motor carried by the machine is. a straper .18

said function is performed by the blades 12 stance from the roadway over which the provide the machanism shown in Figs. 2 and 3. In addition to the intermediate crank 16, of the shaft 7 the said mechanism comprises a vertically-rocking lever, "j ournaled in thebody-at the points21 and have ing a rear area 22 arranged underthe intermediate crank 16 and also havi-ng'forward side a ms 23 that-terminate at their forward ends in eyes 2% in which the rods 17 are loosely arranged as shown. It will be manifest that 1 during the forward stroke of: the rods 17 and the rake 18, the'cranl' 16 will depress the rear lever arm 22,.and in that way raise and maintain in 'raised' position the forward.

arms 23 of the lever and the rods 17 and k 18. 0 the rearward traverse of-them e n i in Figs. 1 to 3 rotatablebrushes may beused rake, howeven the crank '16 will be out of engagement with the lever arm'22, and. this will enable the rake 18 andi appurtenances to gravitate so -that the rearward traverse theraising of the .rake subsequently to the" of the rake will take place while the rake bears on the roadway.- This manner of op erating the rake will be apprec ated as materially advantageous when it is stated that placing of dirt by the same'on the platform 5,-leaves all of the dirt on said platform in readiness for the same tojbe elevated by the.

' blades'12 of the apron 11. Fixed with respect to the body anddisposedimniediately I under the platform 51s a blade 3.0 -wh1chhas for its function to lift from the roadway dirt or other. substance that; may have become caked on the roadway. In order to properly position the blade 30 relative to the surface of a roadway and totak. up ior compensate for wear of the said blade,-"1 mount the rear portion of the body 1 on a shaft 32 that is journaled in bearings car-- rie'dby the body and is provided at its ends with crank arms 33-011 which are mounted loosely wheels 34. Any suitable means may be employed to rockithe shaft 32 about itsaxl 'andraise or depress the rear portion of the body 1 that is fulcrumedor centered on the 1 shaftI'Z. I prefer, however, tdei'nploy for' the purposea beveled gear '35, fixed on-theshaft 32, and a beveled. 'gear;36 that is. ins.

The gatherers 41 may be adjusted and ad ustably fixed byh any suitable means without involving departure from my claimed invention. I prefer, however, to provide the 'gatherers with handles 42 possessed of resiliency, and to,

fix curvilinear racks 13 to. the body 1 in such 5 4 positions that the handles 42fc'an be sprung" .into and out of-seats in the. racks. v In. lieu of the blade-like gather'ers shown as gatherers."
