SWEEPING. ATTACHMENT.

Application filed September 11, 1924. Serial No. 737,111.

To all whom 2'1- may concern:

Be it known that I, JAMES M. FREEMAN, a citizen of the United States, residing at Elizabethtown, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Sweeping Attachments; 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 appert-ains to make and use the same.

The invention has for its object the provision of a sweeping mechanism which may be attached to a tractor, steam roller or other vehicle whereby it may be drawn over the road or other surface to be swept and which may be adjusted as required, and which embodies few parts, said attachment comprising a plurality of sweeper units, which are self-adjustable to conform to the surface to be swept.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention,

Referring to the accompanying drawings forming a part of the specification,

Figure 1 is a side view of a sweeping mechanism embodying the invention, showing the same attached to a propelling vehicle such as a steam roller,

Figure 2 is a top plan view of the sweeping mechanism disassociated from the vehicle,

Figure 3 is a rear View of the attachment,

Figure 4 is a vertical longitudinal section on the line 4-4 of Figure 3,

Figure 5 is a detail sectional view on the line 5-5 of Figure 4,

Figure 6 is a detail sectional View on the line 6-6 of Figure 5, and

Figure 7 is an enlarged detail View of the sweeper adjusting means.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 10 denotes a vehicle such as a steam roller or tractor, the same being illustrated to show the sweeping mechanism in operative position. An angle bar 11 is connected in any preferred way to the vehicle 10 and a second angle bar 12 spaced rearwardly therefrom is connected to the angle bar 11 by means of braces 13 and a plurality of bars 14 are pivotally connected at 15 to the angle bar- 11 and carry brushes 16 which are pivotally connected intermediate their ends to the rear ends of the bars 14 so as to rock and adapt themselves to the nature of the surface over which the sweeping mechanism is drawn. It is observed that the brushes 16 have a two-fold movement, that is vertically with the respective sup porting bar 14 and pivotally about the rear ends of the respective bars 14.

A plurality of guides 17 are provided one for each of the bars 14 and consist of U- shaped frames folded or otherwise attached at their upper ends to the bar 12 and these guides direct the bars 14 in their vertical movements and maintain them in determi nate spaced relation. A lift bar 18 passes be; neath the bars 14 and is supported in guides 19 similar to the guides 17 and attached at their upper ends to the angle bar 12. An operating member 20 attached at its lower end to the lift bar 18 passes loosely through a keeper 21 attached to the bar 12 and is notched in an edge as indicated at 22 to engage a bolt 23 at one end of the keeper 21, whereby to hold the lift bar 18 and the bars 14 elevated when the brushes or sweep ing units 16 are held. elevated from the surface of the road.

When the sweeping i'nechanism is attached to a vehicle whereby it may be drawn over the surface to be swept, it presents the appearance substantially as indicated in Figure 1, and when the bar 18 is lowered, the sweeping units rest upon the surface and sweep the same.

The sweeping units are free to rise and fall and also to pivot about a medial axis, hence, the surface is effectively swept. lVhen required forany purpose the sweeping units may be lifted from the surface of the road by means of the member 20 and held elevated by engaging the notch 22 of said member with the bolt 23.

What is claimed is An attachment of the class described comprising an attaching banaburspuced therefrom and rigid therewith and at a higher elevation, U-shaped guides depending from the second mentioned her, arms passing through said guides and carrying brushes, said arms being pivoted to the first men tioned bar, a lifting bar disposed under said arms, guides for the lifting bar dependingfrom the second mentioned bar and having their openings at a right angle to the open ings of the first mentioned guides, and means to secure the lifting bar in elevated position to the second mentioned bar.

In testimony whereof I affix my signature.

JAMES M, FR EEHEY.
