ALEXANDER S. YOUNG,
OF GALESBURG, ILLINOIS.
SPECIFICATION forming part of Letters Patent No. 746,229, dated December 8, 1903.
A p plioationfi led February 5 1902.
To all-whom, it mayconcern:
- Be it known that I,ALEXANDER S.YOUNG, a citizen of the United States, residingat Galesburg, in the county of Knox and State of Illinois,ha've invented certain new and useful Improvements in Street-Sweepers, of which the following is a specification.
The present invention relates .to that class of sweepers that collect the dirt and deliver it into a cart or wagon as'the sweeper pro-v ceeds.
, It is of course-very-desirable to confine as much as possible the dirt and dust thrown up by the broom, and thus avoid littering the sidewalk and adjoining property, and this is particularly so whenthe sweeper is used during the day, else pedestrians would be annoyed anddiscomfited byclonds of dust; and one object of the present invention is toipro- Vide improved means for accomplishing this very desirable result. To this end I inclose the broom in a hood which is made as tight as circumstances willpermit, and I connect this hood with a closed wagon by means of, a closed chute, in which the upper or ascending lap of the endless conveyor travels. It is also desirable to revolve the broomwith certainty, and thus prevent it from either rolling or dragging upon the ground, else it will not give the dirt the forward impetus necessary to throw it onto the conveyor. ;Heretofore in sweepers of the class .to'which the present riage; but the weight of. thisportionot themachine is notzsuffi'cient t6 producethenecessarytraction under all conditions.
Another object ofthe invention is to provide improved means for driving the broom when the latter is supported by a..carriage which is independent of the collecting-wagon,
a speed proportional to that of the sweeper, and to thisend Id-riveit from the rear wheel of the collecting,- wagon by some suitable mechanism, such as sprocket-wheels and. chain. It is alsodesirable that little or none of the work of dragging the broom-carriage. and itsaccessories be put upon the chute, else it would be necessary to make the chute objectionably heavy in order to give it the neo- Serial No. 92,642. (No model.)
invention is to provide. means independent of thechute for dragging the broom-carriage and its accessories. To this end I connect some part of the broom-carriage with the wagon by means of a draw bar or barsor other suitable device.
Another object of the invention is to pro- .vide improved means'for adjusting the broom vertically. r 1
Another object of the invention isto provide improved means'for adjusting the rear roller, over which the endless carrier runs, in order that it may be placed and maintained in proper relation to the broom.
Other minor objects of the invention will appear hereinafter.
The invention consists in the features of novelty herein described, and in order that it may be fully understood I will describe it with reference -to the accompanying drawings, which are made apart of this specification, and in which- Figure 1 is a side elevation of a streetsweeper embodying the invention with portions broken away. Fig. 2 is a longitudinal section thereof. Figs. 3 and 4 are transverse sections of portions thereof on the lines 3 3 and 4. 4, respectively, Fig. 2.
Only a portion of the receiving wagon or cart is shown in the drawings. It comprises a body portion 1, made of wood, and a housing or
cover 2, resting removably upon Ihe'body portion 1 and forming therewith a tight joint at all points wherethis is practicable. In thefloor of the wagon is a trap-door 3,'held upby anysuitable faslen-ing devic'eand adapted to be let down for emptying thewagon of its contents. In the top of the cap or cover '2 is an openingprovided witna cover 4, which 3 cover may be opened to uncover the opening when it *is .desiredito use the wagon without the means hereinafterdescribed for sweeping1up the dirt and'automatically delivering it into the wagon. At the rear end of the cap or cover2 is a short hollow socket 5, adapt- .ed to telescope with the upper end of achute 6,which inclines downward, its lower end being connected with a forwardly-projecting portion 7 of a drum.8. The chute 6 is closed IOO on allsides from its top to the point of attach- 1 'ment to the hollow projection 7 and has in its top ,an opening closed by a door 60. The
which are slotted at 91 for the passage of a.
shaft 10, carrying the
broom 11, said shaft being jonrnaled in boxes 12, supported by hangers 13, which pass through guide- brackets 13, secured to the heads of the hood. In Fig. 4 the hangers are shown partly in section and partly in elevation. The hangers 13 pass upward through the shaft or axle 15 of the ground- wheels 16, by which all of the rear portion of the sweeper is carried. The portions of the hangers which pass through the shaft 15 are threaded, and nuts 14 are turned onto them and bear upon the top side of the shaft, so that by turning the nuts one way or the other the broom-shaft 10 may be raised or lowered, as desired. The broom derives its motion from one of the rear wheels 16 of the cart or wagon.
17 is a master gear-Wheel secured to the ground-
whee1 16 by means of brackets, clips, or other suitable devices 18. This mastergear-wheel meshes with a pinion 19, secured to a shaft 20, journaled in suitable bearings 21, supported by the wagon. 22 is a sprocketwheel secured to the 20, and 23 is a sprocket-chain passing around the sprocketwheel 22 and also around a sprocket- shaft wheel 24, secured to the broom-shaft 10. With this arrangement the rotation of the ground- wheel 16 will be transmitted to the gear 19, its direction being reversed in the transmission, and the rotation of the gear 19 will be transmitted to the broom-shaft 10 without reversal. The broom is thereby revolved in a direction the reverse of that of the groundwheels, and its lower side sweeps forward, throwing the dirt and dust ahead of it. The dirt and dust thus thrown forward are caught by blades 25, which are secured to an endless belt 26, the blades and belt forming an endless carrier by which the dirt is carried upward and dumped into the wagon. At this upper or forward end the endless carrier passes around a roller 27, fixed to a shaft 28, carrying a pinion 29, which meshes with the gear 19, said shaft being journaled in bearings 30, supported by brackets 31, secured to the sides of the wagon-body. At its lower or rear end the endless carrier passes around a roller 32, carried by a shaft 33, journaled in boxes 34, the boxes being carried by hangers 35, which are adjustable vertically. These hangers pass through brackets 36, secured to the sides of the chute, and pass also through a stout cross-bar 37, secured to the top of the chute and crossing it from side to side. The portions of the hangers 35 which pass through the cross-bar 37 are threaded, and onto these threaded portions are turned nuts 38, bearing upon the top side of the cross-bar, so that by turning the nuts in one direction or the other the hangers 35 may be moved upward or downward, and thus raise or lower the roller 32, by which the rear end of the endless conveyer is carried. The upper run of the endless conveyer travels within 1 the chute, the bottom of the chute being provided at its upper end with a curved sill 39, over which the conveyer passes to the roller 27. The roller 32 is so placed that the blades 25 of the endless conveyer will just clear the ascending side of the brush, and their curved form enables them to retain the dirt better than could be done with straight blades. They are located at sufliciently close intervals to insure that the space between the depending apron-like sides -10 of the chute will always be closed by one'of them, thus preventing any dirt or dust thrown forward from escaping under the conveyer. As will be seen, these aprons 40 extend forward past the.roller 32.
For the purpose of dragging the broom-car riage and relieving the chute ofthis duty draw bars or
rods 41 are used. These drawbars are preferably connected at their forward ends to the axle 42 of the rear groundwheels 16 of thewagon and at their rear ends to the brackets 13, so that there is a direct pull from the rear axle 4:2 to a point on the broom-carriage between its axle and the shaft of the broom. These draw-bars are preferably rigid, so that they will not only draw the rear part of the machine forward, but will also force it backward, and thus prevent injury to the chute in the event of a backward movement of the wagon.
Having thus described my invention, the
following is what I claim as new therein and desire to secure by Letters Patent:
