Application'filed December 14, 1907. Serial No. 406,463.
, 'Be it known that I, FREDERICK A. BISHOP,
' acitizenof the United States, residing at At- ..la1 1ta,1 n the county of Fulton and State of Georgia, have invented new and useful Imirovementsin Street-Sweepers, of which the I tollowingfis a specification.
mac
This invent on relates to street sweeping hines and has for its ob ect to provide a machineof the class referred to oil-simplified and improved construction, embodying a motor and sweeping mechanism which is so mounted and organized with relation to the motor that thelatter is adapted to propel the machine along the roadway and also drive fthe sweeping mechanism, including the suctioniapparatus, while permitting the s'we'elp- Y ing mcchanlsrn'to adjust itself readily to t 10 surface being operated upon.
\llith the above and other objects in view, the nature of which Wlll more fully appear as the description proceeds, the invention consists 1n the novel construction, co'mblnation and arrangement of parts herein fully described, illustrated and claimed.
In the accompanying drawings :'Figure 1 is" a sectional elevation of a street sweeping .machine embodying the present Fig. 2 1s a s de elevation thereof.
invention. 7 Fig. 3 is an enlarged vertical cross .section through the machine on the line 33 of Fig. 1. Fig. 4 is a vertical sectional view of the separator. Fig. 5-is a detail side elevation of the lower v ortion of the trash box, showing the door I olding and releasing mechanism.
The nachme comprises a suitable body 1 i: fniounted upon a truck or wheel frame 2 sup-.
ported u on carrying imparte wheels 3, motion being to the machine for propelling the same by an engine 4 mounted in a suitable geared by means of a drive shaft 6', chain 7 an'd counter-shaft 8 to the rear axle 9, the driving mechanism thus far described being similar to that now employed on automo- 'biles.
' 1O designates the operators seat and 11 the steering wheel by which the machine is controlled! At therear of the machine is arranged a trash box 12 into which empties a separator 13 having a conical lower portion 14 which sets into the upper part of the trash box 12 the machine and and is secured thereon by means of a flange or brackets 14. The separator has communicatingtherewith a dust and trash conveyer '15 consisting of a pipe of suitable size .while within the separator is a deflector 16 a ainst which the material is thrown by the action of the fan blast, the trash passing downward through the separator into the trash box 12 while the air passes out through a central opening 17 in the to of the separator as shown in Fig. 16, the eflector being of l'rusto-conical shape and serving'as a guard for the o ening 17. In advance of the trash box 12, t e pi e 15 communicates with a fan casing 18 in w ich is mounted fan that sucks the air in centrally through a suction head 19. The u per end of this suc= tion head is round or su stantially so where it communicates with the fan casing, and from said pointdownward, the head expands in width as shown in Fig. 3 until the lower end thereof is practically the full width of the machine and ({uite narrow as illustrated in Fig. 1 so as to ie between a pair ofswoeping brushes 20 and 21. The brushes 20 and 21 operate on the suction head 19 as clearly shown in Fig. 1 and while one of said brushes is provided with a continuous covering of bristles, the other brush 21 is preferably provided with pockets or intervening spaces 22 between the several groups of bristles, said brushes rotating in opposite directions as indicated by the arrows in Fig. 1.
The brush 20 is journaled in bearings in the lower ends of a pair of oppositely arranged hangers 23 while the other brush 21 is journaled in the lower ends of another pair of oppositely arranged hangers 24. The hangers 23 and 24 are connected by pivotal arms or links 25 and 26 to common supports 27 whereby said hangers 23 and24 are adapted to move up and down while providing bearings for the axles of the brushes 20 and 21. O
passes a sprocket chain 29 that rotates around another sprocket wheel 30 on the shaft of the brush 20. The other arm 26 "carries a sprocket wheel 31 around which runs a chain 32 that passes around another sprocket wheel on'the brush 2 1 corres 0nding with the sprocket wheel 80 on the rush a rotary opposite sides of the lower end of of the arms 26' carries a sprocket whee 28 around which 20. The wheels 28 and 31 are driven in opposite directions by a sprocket chain 3-3 which extends forward and passes around a driving sprocket wheel 34: fast on a shaft extending transversely of the machine, the shaft 35 also carrying a crown gear wheel as which is driven by a bevel pinion 37 on one end of a shaft 38 having at its opposite end another bevel pinion 39 which meshes and is driven by a bevel pinion 4.0 on the driving shaft 6 of the machine. By means of the driving connections just hereinabove described, rotary motion. is imparted to the brushes .20 and 21 and they are simultane ously driven in opposite-directions so as to gather up the trash and subject the same to the suction of the fan, causing such trash to be drawn into the suction head -19 and propelled by the fan through the conveyor 1:3 into the separator 13 and finally into the trash box 1 v The brushes 20 and 21 are housed in a suitable protecting hood comprising a stationary or fixed section 41 and a movable telescopic lower section 42 adapted to slide up and down within the fixed section All. The movable section 42 is supported and carried'by theraxles ofthe brushes 20 and 21 the extremities of said axles, after passing through the hangers 23 and 24', being .journaled in openings in'the hood section 42 i' as shown at 43. and fall automatically, the movable hood asection -42 correspondingly raised and 35-" Thus, as the brushes rise lowered, thus keeping the lower edge of the hood at the proper distance from the surface on which the machine is operated. i The trash box 12 has reversely inclined slopingwalls 4E4 while the bottom 45 is composed'of a air of drop doors meeting at the center and ged attheir opposite edges as shown at 46 so asto adapt said doors to drop downward as indicated in dotted lines in Fig. 1 to empty the trash box. The doors 45 are upheld by a pair of L-shaped catches -47 as shown in Fig. 5, which catches engage pins 48 on the doors. These catches are provided with inwardly extend ng overlapping slotted arms e9 connected by an eye or ring 50 to which is attached a flexible connection 51 which leads upward and forward passing through suitable guides v52 and 53, said connection being attached at its for ward end to within reach of the driver on the at 10 who by pulling on the handle 54, operates he oat-case 7,releasing erases the drop doors l5 and discharging the trash I in a pile on the roa l-way.
claim s e 1- street sweeping machine comprising m opposed rotary brushes mounted es adapted to rise and fall, hangers in connecting the hangers with the frame and permittm said hangers to use and fall, and
means for actuating said brushes including journaled, sprocket driving mechanism for said brushes carried by the hangers and movable up and down therewith. while in operation, and a motor geared to the driving mechanism of the brushes.
3. A street sweeping machine comprising opposed rotary brushes, swinging-link supported hangers in which said brushes are jourmrled, sprocket driving iechanism for said brushes carried by the hangers and movable up and down therewith while in operation, a motor geared to the driving mechanism ol the brushes, and a telescopic inclosing hood for said brushes embodying a movable section which. is connected with the brushes and adapted to rise and fall therewith. 1
4. A street sweeping'machine comprising opposed rotary brushes, link-supported hangers by which said brushes are carri'edand rendered movable up and down, a suction head having a laterally extended lower or;- tremity which lies between the brushes, a suction fan communicating with said head,
a trash box, a conveyor pipe leading from the fan to'the' trash boX, means including a motor for simultaneously driving the brushes and fan sprocket wheels carried by said hangers, and sprocket chains for transmittin motion to the brushes through said sprocket wheels.
