The present invention relates to improvements in brushing or sweeping devices and has reference more particularly to an attachment for a motor vehicle equipped with pneumatic tires, the primary object of the invention residing in the provision of a brushing attachment for clearing the path of the front wheel of the vehicle of and removing therefrom, broken glass, nails, tacks or any other obstructions that may be encountered and which would puncture or otherwise damage the pneumatic tires of the front wheels of a vehicle.

One of the important objects of the invention resides in the provisions of a brush attachment that can be readily and easily installed on an automobile without necessitating any material alterations of the parts with which the brushing attachment is associated,

the device being at all times positiveand efficient in carrying out the purposes for which it is desired.

A further object is to provide a brush attachment for vehicles of the above mentioned character wherein means is provided for adjusting the height of the brushing or sweeping member with respect to the ground, additional means being provided to permit swinging movement of the brush head when the same strikes a large obstruction so that the brush head may pass over said obstruction without causing damage to the brush attachment.

Still a further object is to provide a brush attachment wherein the parts are so arranged as to deflect the broken glass, nails or the like to one side of the road.

Still a further object is to provide a brush head attachment of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purposes for which it is designed.

Other objects and advantages will become apparent during thecourse of the following description.

In the accompanying drawing, forming a part of this specification,and in which like numerals indicate like parts-throughout the same:

Serial No. 321,500.

Figure 1 represents a front elevation of the brush attachment embodying our invention showing the manner in which the same is mounted on an automobile.

Figure 2 is a side elevation showing front and rear brush units,

Figure 3' is a vertical sectional view through one of the brush units,

Figure 4 is a top plan view for more clearly disclosing the attaching means for a brush unit,

Figure 5 is a sectional View taken approximately on the line 55 of Figure 4 looking in the direction of the arrows,

Figure 6 is a sectional view taken on the line 6-6 of Figure 3,

Figure 7 is a detail view showing the means for adjustably securing the lower frame in the stationary upper frame and,

Figure 8 is a detail perspective View of the removable brush.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of our invention, the numeral 1 designates a substantially rectangular. shaped channeled frame that is curved as suggested in Figure 6.

This frame is disposed in front of as well as directly rearwardly of each of the front wheels A of an automobile. The supporting means for the frame disposed forwardly of each front wheel includes the upper and lower rods 2 and 3 respectively. The forward ends of these rods are secured to the inner side portion of the frame 1 while the rear end of said rod has connection with a vertical plate 4 that is disposed against the front axle B in the manner as clearly suggested in Figures 4: and 5.

A similar plate 5 is disposed against the rear side of the'front axle and suitable securing bolts 6 extend through the unner and lower ends of the alined plates 4 and 5 for engagement with the upper and bottom'faces of the front axle to rigidly secure the plates in position as also shown in Figure 5.

Additional rods 7 extend from the stationintermediate portions of the rods 2 and 3 and brace rods 9 extend laterally from the cross piece 8 to a plate 10 that is disposed against the front side of the front axle B inwardly of the plate 4.

A plate 11 is secured against the rear side of the/front axle B in alinement with the plate 10 by bolts 12.

The stationary frame of the rear brush unit is supported in a similar manner. The rods that extend from the plate5 to the frame of the rear brush units are shown at 13 and 14: respectively while the brace rods that extend from the plate 11 are indicated at 15.

Upon referring to Figure 7 it will be observed that the frame 1 is provided in its front side with a screen 16, the edges of the screen being disposed within suitable channels formed in the respective sides of the frame. j Each brush unit includes a slidable lower frame 17 which is also slightly curved and this frame 17 is slidable between the channeled sides of the stationary upper frame 1 through the bottom of thestatio'nary frame. A handle 18 extends across the rear portion of theslidin'g frame 17 for manually raising and lowering the "frame and for the purpose of holding the slidable frame in any vertically adjusted position with respect to the stationary upper frame 1, we provide the set screws 19 that extend through the opposite sides ofjthe stationary frame l'and'en gage with the adjacent side edges of the slidable frame in the manner as also clearly disclosed in Figure 7.

The slidingframe 17 is covered with -a screen 20. Each brush unit further includes edge of this strip of rubber being attached to the lower edge of the sliding frame 17 by "suitable clamping plates or strips 24; as shown in :Figure 3. V

The purpose of the rubber connecting strlp .23 between the frame 17 and the brush head from the rear side of the housing 27, the

lower edgeof thisfplate terminating above the ground engaging portions of the bristles 28. A

When the brush units are positioned in front of and directly behind the front wheels of the automobile, the lower frame 17 is properly adjusted so that the bristles 28 engage the ground, it will be readily apparent that the bristles of the brush and the brushes will sweep away to one side any obstacles such as pieces of broken glass, nails, tacks "and other sharp elements from the path of readily and easily atmchedin proper position on the automobile without -Iit-lcess'itating any alterations. I

Furthermore the brush attachment will at all times bepositive and efficient in carrying out the purpose for which it is designed and due to its simplicity the same can be manufactured at a very lowcost and yet be strong and durable. v

Should the bristles 28 wear away so as to -render the brush ineflicient in its operation,

the brush may be readily andeasily removed and replaced vv'ith a new one. i Y Y While we have shown thepreferred embodiment of our invention, it is tojbe understood that various changes in the size, shape "and arrangement ofpartsmay be resorted to without departing from "the spirit of the invention'a'nd the scope ofthe appendedclaims.

7 Having thus described our invention, What we claim as new is:

,1. In a brush attachment for automobiles,

a'vertical member for disposition infront'of each of the front wheelsgof the automdbile,

supporting means for said member, an additional member having its upper portion slid- -ably associated with the stationary firstmentioned member, means for adjustably securing'the movable member with respect to the stationary member, a brush for engagement with the ground, and a flexible connection between the brush and thelower [edge of the slidablemember, said flexibleconnection'comprising a strip of stiff rubber secured at its lower endto the head of the brush, the upper edge of the 'strip of rubber "being secured "to the loweredge of the slidable member.

,2. In brush attachment for automdbiles, "a vertically disposedchanneled frame for "arran-gement in front of each of the front wheels of an aut'omobile, supporting means therefor, a screen mounted 'inthe stationary frame, an additional frame'slidably mounted in the channeled frame, a screen carried by't'he slidable frame, means for adj ustably securing the slidable frame in any vertically adjusted position, a brush for engagement with the ground, and resilient means interconnecting the brush and the lower edge of the slidable frame.

3. In a brush attachment for automobiles a vertically disposed channeled frame for arrangement in front of each of the front wheels of an automobile, supporting means therefor, a screen mounted in the stationary frame, an additional frame slidably mounted in the channeled frame, a screen carried by the slidable frame, means for adjustably securing the slidable frame in any vertically adjusted position, a brush for engagement with the ground, and a strip of stiff rubber secured at its lower edge to the head of the brush, the upper edge of the strip of rubber being secured to the lower edge of the slidable frame.

In testimony whereof we affix our signatures.
