STREET-CLEANER.

Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed January 9, 1912. Serial No. 670,329.

To all whom it may concern:

Be it known that I, JOHN B. GRAVELLE, citizen of the United States, residing at Asbury Park, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in Street- Cleaners, of which the following is a specification.

This invention relates to street cleaners, and has for its object to provide a cleaner in the form of a barrow adapted to be propelled over the surface of the street and provided with a rake attachment for the purpose of moving material from the surface of the street up into the body of the barrow.

A further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which: 7

Figure 1 is a perspective view of the cleaner; Fig. 2 is a sectional view of the same; Fig. 3 is a bottom plan view of the cleaner; Fig. 4 is a perspective view of portions of the cleaner, showing the manner in which the rake operating rods may be interlocked.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

The cleaner includes a body 1 which constitutes a barrow, formed from sheet metal and shaped up as will be explained hereinafter. The said body 1 is mounted upon wheels 2 which are located in the vicinitv of the rear edge thereof. Handles 3 extend rearwardly from the body 1 and are connected together by a cross bar 4. Each handle 3 is provided at a point near the body 1 with a grip 5. The said grips are disposed inwardly with relation to the said handles. The body 1 is provided at its sides and at its forward end with eyes 6 to which trace chains may be attached when it is desired to move the cleaner by the use of a draft animal. The body 1 is formed from a blank having a bottom portion 7, side portions 8 and an end portion 9. Reinforcing angle irons 10 are applied to the meeting edges of the sides 8 and bottom 7 and the end 9 and bottom 7. A stiffening strip 11 is applied to the under forward side of the bottom 7 and a strip 12 is applied to the upper side of the strip 11 so that the upper surface of the strip 12 is flush with or in the same plane approximately as the upper surface of the bottom 7. hen the strip 12 is worn to such an extent as to be useless it may be removed from the strip 11 and a new one substituted in its stead.

Guides 13 are mounted at the upper edges of the sides 8 and a rod 14 is located between the said guides and the upper edges of the sides 8. The said rod is held against longitudinal movement with relation to the said sides by means of heads 15 fixed at the ends thereof.

A rake member 16 is mounted upon the rod 14 and is provided with an upwardly and forwardly projecting arm 17. A guide 18 is mounted upon the end 9 and a rod 19 passes through the said guide 18 and is pivotally connected at its forward end with the upper end of the arm 17. The rod 19 is provided at its rear end with a grip 20 and at a point in the vicinity of its rear end with a laterally disposed lug 21. A bail 22 is attached to the upper portion ofthe rake 16 and extends rearwardly therefrom. A rod 23 passes through the guide 18 and is pivotally connected at its forward end with the intermediate portion of the bail 22. The rod 23 carries an eye 24 which slidably receives the rod 19. The rod 23 is provided at its rear end with a grip 25 and at a point in the vicinity of its rear end with a laterally disposed lug 26.

It will be seen that the body 1 may be propelled over the surface of the street and brought in contact with the material lying thereon, and by moving the rods 19 and 23 through the guide 18 the rake 16 may be dis posed over the said material. By moving the rods 19 and 23 alternately in opposite directions the rake 16 will be swung upon the rod 14, whereby the said rake will encounter the said material and sweep the same back upon the bottom 7 of the body 1. By drawing the rods 19 and 23 rearwardly at the same time the said rake will pull the material back toward the end 9 of the said body.

As illustrated in Fig. 4 of the drawings the lugs 21 and 26 carried by the rods 19 and 23 respectively may be interlocked with each other so that by pushing the rod 19 the rod 23 will be moved longitudinally in a forward direction, and by pulling the rod 23 the rod 19 will be moved rearwardly. Thus the rake member 16 will be moved bodily without tilting or swinging the same upon its supporting rod 14.

In some instances where the surface of the pavement or street is not level but is rounded in an upward direction, it is desirable to slightly buckle the body 1 so that the strip 12 will fit snug against the bowed surface of the street. To accomplish this, ears 28 are located at the ends of the body 1 and rod sections 29 are connected with the said ears. The inner ends of the said rod sections 29 are connected together by a turnbuckle 30. A rod 31 is provided with branches 32 which are connected with the rod sections 29 beyond the ends of the turnbuckle 30. The rod 31 is connected at its rear end with a lever 33 which is pivoted to the bottom of the body 1 and which is arranged to engage a dentate member 34, also attached to the body 1. Therefore it will be seen that by swinging the lever 33 the rod 31 will be moved longitudinally, whereby the inner ends of the rod sections 29 may be swung rearwardly and thus the said rod sections are moved out of alinement with each other. This movement on the part of the said rod sections will have a tendency to buckle or arch the bottom 7 of the body 1, so that the strip 12 will fitsnugly along the surface of an arched pavement.

Members 35 are pivotally attached to the end walls 8 of the body 1 and when not in use may be swung upwardly and inwardly within the said walls as indicated in Fig. 4 of the drawings. hen these members are in use they are swung so that their forward port-ions project in front of the forward edge of the strip 12 as indicated in other and adapted to be moved to swing the rake and move the rake along its sustaining guides.

2. A cleaner comprising a body having sides provided with guides, a rake supported in the guides, a guide mounted upon the rear end of the body, and rods slidably received in the last mentioned guide and guided with relation to each other by an eye carried by one of the said rods, said rods being connected at their forward ends with the rake at the opposite sides thereof.

A cleaner comprising a body, rods connected with the ends thereof, and a lever mechanism mounted upon the body and connected wit-lithe said rods to move the same to buckle the body.

1. A cleaner comprising a body, rods connected with the ends thereof, a turnbuckle connecting therods together, a lever mechanism mounted upon the body, and a rod connecting said lever mechanism with the first mentioned rods.

In testimony whereofI affix my signature in presence of two witnesses.

JOHN B. GRAVELLE.
