JOHN IIASSON, OF READING, PENNSYLVANIA.
SPECIFICATION forming part of Letters Patent No. 600,222, dated March 8, 1898.
Application filed september 25, 1897. Serial No. 652,972. (No model.)
T0 at whom it may concern.-
Be it known that I, JOHN HASSON, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Street-Sweepers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in combined street sweepers and sprinklers.
The object of the invention is to produce a sweeper of simple construction and easily operated.
The invention is fully described in the following specification and clearly shown in the accompanying drawings.
Figure l is an elevation of my sweeper. Fig. 2 is a rear end view of the same.
The body A of the wagon serves as a water-tank, the water contained therein being conducted to a perforated pipe B, extending the full width of the vehicle and immediately in front of the rear wheels, whereby the surface to be swept is moistened just previous to the action of the brushes.
Two arms 0, pivotallyattached at their upper ends to the body A, carry the sweeper D, pivotally attached to their lower ends. This sweeper consists of a series of bunches of bristles O, secured to a suitable frame 0 To the front side of this frame is secured a metal scraper E, which reaches nearly to the lower edges of the brushes or brooms.
To the rear end of the bodyA is secured a pulley F, over which a flexible cord passes, the one end of which is secured to the frame C and the other end to the lever G. This lever G is pivotally secured at its lower end to the forward end of the body A, and the cord h is attached to it near its upper end.
When a sufficient amount of sweepings have been gathered, the lever G is pushed forward, raising the brushes, allowing them to pass over the sweepings, and when the lever G is released it will drop the brushes again to the surface of the street.
The scraper serves to loosen anyhardened substance over which it passes, so that the sweeper may brush it along.
Should the scraper strike a stone or other obstruction, the frame will be raised on its pivotal connection and pass over it.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
In a combined street sweeper and sprinkler, a tank having a depending pipe B attached thereto, arms 0 pivotally attached at their upper ends to the tank, their lower ends pivotally connected to and carrying a frame provided with brush-bristles and a scraper, a lever G secured at its lower end, pivotally, to the front end of said tank and having a flexible cord attached thereto and passing over a pulley secured to the rear end of the tank, the lower end of said cord attached to the frame of brushes and adapted to lift said brushes, all substantially as and for the purpose set forth.
In testimony whereof I affiX my signature in presence of two witnesses.
