Specification of Letters Patent.

Application filed May 10, 1907. Serial No. 372,950.
To all whom it may concern:
Be it known that I, JOHN THOMAS WVHIT- TOME, residing at Parkwood Road, Tavistook, in the county of Devon, England, have invented a Combined Street-Sweeper and Collector; and I hereby declare that the following is a full, clear, and exact description of the same.
This invention relates to a combined street sweeper and dirt collector, which will sweep the dirt from the surface over which the apparatus passes, collect it into a receptacle provided for that purpose, and convey it by an elevator or carrier from the receptacle to a cart or Wagon.
It further relates to a means for automatically moving the dirt in the receptacle into the path of the elevator or carrier, and to a means by which the elevator of carrier is enabled to pass any obstacle which enters its path.
For an understanding of the invention reference is to be had to the following description and to the accompanying drawings, in which, v
Figure 1, is a side elevation of a sweeper and cart with one side of the elevator removed. Fig. 2, is a side elevation of a sweeper, showing a modification of the construction illustrated in Fig. 1, with the elevator side removed. Fig. 3, is a rear elevation of the sweeper shown in Fig. 2, with the sweeper brush removed. Fig. 1, is a detail view of the mechanism for actuating the side scrapers operating in the dirt receptacle. Fig. 5, is a plan view of the mechanism shown in Fig. 4:. Fig. 6, is a detail view of one of the elevator buckets shown in Fig. 1. Fig. 7 is a detail view of one of the elevator buckets shown in Figs. 2 and 3. Fig. 8, is a view showing one set of elevator scrapers. Fig. 9, is a side view of one of the scrapers shown in Fig. 8.
Like characters of'reference refer to like parts throughout the specification and drawings.
Referring to Fig. l; the rotary brush B is revolubly mounted in the arms I) rockably mounted on the shaft G, journaled in the sweeper frame, so that the brush can accommodate itself to the surface over which it is moving. Power is transmitted to the brush by chains G passing over sprocket wheels G on the shaft G and sprocket wheels G on the brush shaft. The shaft G is driven by chains Cr passing over sprocket wheels Gr mounted on a sprocket wheel shaft 9 and other sprocket wheels (not shown) on the shaft G. The sprocket wheels G are driven by pinions G on the axle a and pinions (not shown) on the sprocket wheel shaft g.
The lower part of the elevator casing P forms a dirt receptacle P having an opening P, through which the dirt fromthe brush B is thrown into the dirt receptacle. Pivoted to the lower edge of the opening P is an apron b", which together with the brush B may be vertically adjusted. This adjustment is effected by chains or cords b connecting the apron b with the arms I) and the latter with the rocker beams 5 The rocker beams b are fulcrumed to the sweeper frame at b, and pivotally connected to the rocker beams 12 and to the adjustment levers b are links 6 The adjust-- ment levers b are fulcrumed to the standard b, and are operated to respectively raise or lower the brush B. Pivoted at C -to the dirt receptacle P are arms C in which is mounted a shaft c fitted with sprocket wheels 0 and journaled at the top of the elevator is a shaft 12, on which are mounted sprocket wheels H. Passing around the sprocket wheels H and c are sprocket chains C to which are secured the buckets C. Mounted on the shaft n is a sprocket wheel m driven from the shaft G, by a chain G Idlers h are provided for the sprocket chains C immediately below the sprocket wheels H. The buckets carry the contents of the dirt receptacle over the sprocket wheels H, and deposit the said contents through the delivery spout P into the cart. The arms C are provided with studs C vertically movable in the slots C of the hanger arms C the latter being pivoted at C to the elevator sides, so thatwhen an obstacle obstructs the path of the buckets C, the sprocket shaft 0 can move upwardly to enable the bucket or buckets to clear the obstacle, and resume its normal position by gravity when the obstacle has been passed.
Connected to the front of the sweeper is an axle upon which may be mounted one or more guide wheels E, and attached to the front of the sweeper is a draw bar F.
The construction shown in Fig. 2, is in many respects similar to that shown in Fig. l, but in this case the drive wheels A, are situated closer to, the elevator, and the drive wheel axle a is provided with cog wheels A meshing with cog wheels a on the shaft G. In Fig. l, the sprocket wheels I-I are shown to be of greater diameter than the sprocket wheels 10 shown in Fig. 2, and in the latter figure the idlers h shown in the former figure are dispensed with. In Fig. 2, the adjusting levers b are pivoted to the elevator frame instead of to the standards 5 as shown in Fig. 1, but otherwise the general principle of the construction and operation of the parts shown in Fig. 2, is the same as that in Fig. 1.
Means are providedfor moving the dirt in the dirt receptacle P into the path of the elevator buckets C, and for scraping the dirt away from the delivery spout P of the elevator to prevent it accumulating at that place. The means for moving the dirt in the dirtreceptacle into the path of the elevator is shown in Figs. 3, 4E and 5, and may be described as comprising scrapers D working from the ends of the dirt receptacle P toward the elevator buckets C. The scrapers D are connected to scraper arms d having guide plates d formed with guide slots d, to receive the crank pins d attached to the bevel wheels d The bevel wheels d are g mounted to revolve on studs 03 projecting from the standards 03 secured to the sweeper frame and their rotation is effected by bevel wheels d on the shaft G. During the rotation of the bevel wheels 0Z the crank pins d engage in the guide slots d, and move the scrapers from the position shown in the full lines, to that shown in dotted lines in Fig. 8. During the movement of the scrapers, from the position shown in full lines to that shown in dotted lines, the crank pins cl engage with the bottom ends of the guide slots al and drag the scrapers along the bottom of the dirt receptacle. During the return of the scrapers from the position shown in dotted lines, to that shown in full lines, the crank pins 03 engage at the top of the slots and lift the scrapers from the bottom of the dirt receptacle.
I To prevent the accumulation of the dirt in the delivery spout P a scraping device is provided consisting of scrapers 70 provided with scraper arms 72 mounted on a crank shaft k driven by a chain 70 from the shaft n. The ends of the scraper arms 70 are connected by links is pivoted to the elevator frame. The rotation of the crank shaft 70 carries the scrapers in an outward direction along the bottom of the delivery spout P to eject the dirt resting thereon, and during the return movement, the scrapers 7a are raised above the bottom of the delivery spout until they attain its inner end, when they are lowered into engagement with it.
In the operation of the apparatus the drive wheels A revolve the shaft (4 and the revolution of the shaft (F'revolves the cog wheel A which meshing with the cog wheel (1 causes the revolution of the shaft G. The revolution of the shaft G, through the agency of the bevel wheels d revolves the bevel wheels d and crank pins d, to oscillate the scrapers D between the ends of the dirt receptacle and buckets C. To hold the scraper arms and scrapers in a position where they will be obliged to complete the full distance of their travel, links cl are connected to the scraper arms (Z and to a pivot plate (Z secured to the elevator.
I claim 1. In a combined street sweeper and collector in combination, an axle, two ground wheels mounted thereon, a dirt receptacle suspended from the axle of the ground wheels, an elevator to remove the contents of the dirt receptacle, an elevator driving means actuated by the ground wheels, two scrapers within the dirt receptacle and lo-- cated one on each side of the elevator, and provided with scraper arms extending beyond the dirt receptacle, links pivoted to the scraper arms and to the elevator, and means I for imparting reciprocating motion to the scraper arms and scrapers actuated by the elevator driving means.
