T0 at whom it may concern:

Be it known that I, HORACE BORDEN, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Street-Cleaning Machines, of which the following is a specification.

The object of my invention is to provide a street-cleaning machine which will scrape accumulations of dirt and refuse from an uneven and irregular street-surface as well as from an even and regular surface. This object I attain by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view of the machine. Fig. 2 is a top view of the same, showing a portion of it in dotted lines; and Fig. 3 is a plan View showing a variation in the arrangement of the scrapers.

Similar letters refer to several views.

The letter (1 represents the scrapers, con sisting of metallic blades of suitable width and length securely attached to rods 0, which rods are hinged to the draft-beam g, which beam is supportedby a wheel Z.

3' represents portions of the frame of the machine rigidly secured to the beam v9 and extending rearwardly to near the scrapers a, where crossbars i and i are secured to them,

similar parts in the which cross-bars carry the guides h. The

tions j, as shown guides it serve to prevent lateral movement of the rods 0, and the cross-bars i and i are a suitable distance apart to allow the necessary vertical movement of the scrapers a. The handles it are bolted to the frame porin Fig. l, and it is obvious that when the handles it are raised the scrapers a are also raised. The scrapers a are shown with their edges overlapping; but this is not essential, though perhaps convenient.

It is obvious that the outer scrapers might be rigid, with no vertical motion, and in that case the intermediate scrapers would accommodate themselves to the unevenness of the street and attain the end desired; but it is deemed advisable to give each scraper an independent vertical movement.

en the scrapers are arranged as shown in Fig. '2, the machine is especially designed to clean the gutters of a street by being drawn along the same by a draft-animal, a man guiding it by the handles and dumping the same when required. This operatlon puts the dirt in piles convenient to be shoveled into carts to be transported to the dump. When the scrapers are arranged as shown in Fig. 3, the machine is designed to scrape the dirt from the whole width of the street into the gutter, ready to be scraped into piles by the machine. (Shown in Fig. 2.)

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. A street cleaning machine, having a series of scraping-blades, each blade having an independent vertical movement; and means to simultaneouslyraise said blades over an accumulation in front of them, substantially as described.

2. A street-cleaning machine, having a series of scraping-blades overlappingeach other, and each having an independent vertical movement; and means to raise said blades over an accumulation in front of them, substantially as described.

3. A street-cleaning machine, having a series of scraping-blades, a majority of which have an independent vertical movement, and means to raise said scraping-blades over an accumulation in front of them, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.

HORACE BORDEN.
