Specification of Letters Patent.
Patented June 15, 1915.
Application filed October 1, 1914. Serial No. 864,445.
To all whom it may concern Be it known that I, DANIEL SrLLo, subject of the King of Hungary, residing at Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Street-Sweepers, of which the following is a specification.
This invention relates to certain new and useful improvements in street sweepers.
The primary object of this invention is to provide a street sweeper adapted to be drawn or propelled for sweeping the roadway of a street and positioning the sweepings centrally and forwardly of the device in position to be collected by an endless conveyer operable by the movement of the devlce.
With this general object in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts to be hereinafter more fully described, illustrated in the accompanying drawings and set forth in the appended claims.
In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views, Figure 1 is a side elevation of the device with two of the wheels and the drawing tongue mechanism removed, the axles being shown in section while the brush is shown in end elevation to better illustrate the adjacent parts. Fig. 2 is a top plan view of the device partially broken away. Fig. 3 is a similar view of the main frame of the vehicle detached. Fig. 4 is a front elevational view of the main frame and the auxiliary frame with the forward wheels partly broken away. Fig. 5 is a longitudinal sectional view through one of the conveyor buckets.
Referring more in detail to the drawings, the vehicle portion of the device comprises a frame including side rails 10 having a rear axle 11 journaled in the rear ends thereof and having rear wheels 12 fixed upon the opposite ends of the said axle, while a forward axle 13 is provided having a cross bar 11 positioned thereabove and with a connecting block 15 secured to the forward converging ends of the rails 10 positioned between the said bar and front axle and having the king-bolt 16 extending therethrough. The front wheels 17 are journaled upon the end spindles 18 of the front axle While a drawing tongue 19 is connected to the front axle by means of forwardly converging connecting strips 20.
Resilient brackets 21' are secured to the rails 10, projecting forwardly thereof and being slightly divergent and are secured to the bar 14:. The brackets 21 have curved lower ends 22, to the lower end of each of which a support 24 is hinged at 26 for mounting sweeping brushes 23 which are journaled in the said supports and are normally positioned rearwardly convergent as shown in Fig. 2. Hinged connecting straps 25 extend between the supports 24 and the horizontal portions of the brackets 21 whereby the supports 21 may be moved upwardly upon the hinge pins 26 that connect the sup ports to their respective brackets.
Supporting rods 27 are secured to the rails 10 and the bar 14:, being positioned outwardly of the brackets 21, and have their forward ends downwardly curved with a shaft 28 journaled therein above and rearwardly of the axial line of the brushes 23. An auxiliary floating frame or platform 29 is secured by means of bolts 30 at the rear end thereof to the rear end 31 of the rails 10, the said platform extending forwardly above the said rails and being otherwise unsupported in spaced relation thereto. The platform has lower longitudinal grooves 70 receiving the brackets 22 when the front of platform is sprung downwardly. A shaft 32 is journaled in spaced posts 33 substantially centrally of the platform 29 and is provided at one side of the platform with a grooved pulley wheel 3 1 and also a sprocket wheel 35. The rear axle 11 has a sprocket wheel 36 secured thereto and adapted to turn therewith while a sprocket chain 37 runs over the said two wheels 35 and 36 whereby a forward movement of the vehicle imparts a counter-clockwise movement to the pulley wheel 34.
Forwardly on the platform, similar spaced posts 38 are mounted for journaling a shaft 39 which has a pulley wheel 40 secured to one end thereof and over which a crossed belt 11 is adapted to pass and which belt also passing over the pulley wheel 31 results in a clock-wise rotation of the pulley 10 during the travel of the vehicle. A sprocket wheel 42 is secured to the shaft 39 centrally between the posts 38 and a sprocket chain 13 which forms the carrying member of an endless conveyeris adapted to pass thereover and be propelled thereby. Rear posts are carried by the platform 29, having an idler sprocket wheel 45 centrally positioned and journaled in the upper ends thereof and over which the conveyer chain 'also passes.- "A similar sprocket wheel l6 is secured to the shaft 28 of the supporting rods 27 and the sprocket chain 4E3 passing over the said wheel46 revolves the shaft 28 and pulleys A7 which are secured thereon and at opposite sides of the sprocket wheel/l6. V
Pulleys 48-are fixed uponhthe inner ends 49'of the brush axles, and belts 50 passing over the pulleysf l'Tand 48 result in revolving the brush-es 23 in the sweeping operation during the =movement of the sprocket-chain A3 at all times during-the travel ofthe vehicle. Side bars 51 are carried by the platform29 and downwardly project therefrom and have a road-scraper 52 secured at their lower ends, thesaid scraper-having acut awayforward portion 53 through which the collecting buckets 54 that'are mounted upon the chain 43' will pass during the collection of the sweepingsby the said buckets- These buckets 54L are mounted upon the outer side of the'sprocketchain d8 which chain is an endless one and passes over the sprocket wheels42,'4:5-. and 46 as hereinbefore noted and 'also passes through a central opening 55 of theplatform29 and between the side rails '10-of the main :frame. The buckets 54 are provided with rollers 56- upon the bottoms thereof While the forward end of the bottom-57 of each bucket is sharpened as at 58. A collection receptacle 59 is mounted by means of brackets 60 to-the rear end of the platform 29 and-has a' hinged bottom 61 provided with a'spring-pre'ssed catch 62.
The operation of the-device will be at once apparent from this detailed description as the forward movement of the vehicle whether drawn by horses or motor results in turning the power sprocket wheel 4:2 which propels the conveyerchain A3, thereby turning the shaft28 and'the sweeping brushes 23. r The sweepings are brought centrally in front of the conveyer and the movement of the buckets thereof along. the ground collects the sweepings :and elevates them in a manner that will be v apparent until the buckets are turned upside down by passing over the'sprocket 45 which action=drops the sweepings from the buckets into the receptacle 59-wherethesa me may be removed by opening the bottom=6l thereof. The passing of the'conveyer buckets through the scraper 52 allows the bucketsto collect any sweepingsthat the scraper has gathered up and in this manner the .conveyer takes up all-of the sweepings leaving the ground or road surface' freeand clean of all sweepings and refuse.
It will be noted that the brushes are nor mally positioned upon the ground-horizontallybu-t may be elevated and retained out of contact with the ground by moving the sameupwardly upon their hinged pins 26 k which is made possible by the pivotal folding" movement of the supporting. straps 25.
WVhile I have shown and described the preferred embodiments of my invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit andscope of the 1nvention as set .forth' inthe claims.
