'7 Claims.

This invention relates to a brush construction suitable for the cleaning of an automobile chassis, particularly the wheels and running gear of the vehicle.

Heretofore in order to clean between the spokes and particularly where the spokes join to the hub of the wheel, it has been necessary to whipsaw rags, or the like, between said spokes at the junction with the hub in order to completely clean the wheel. Tapered brushes have been employed, but these mar the wheel, because the tip was not protected.

The present invention is directed to a tapered brush construction, wherein the tip has a certain cooperating relation with the bristle support of the brush and the end bristles of the brush, so that in the insertion of the brush between the spokes, the paint, enamel or lacquer will not be marred and upon withdrawal of the brush between the spokes, the tip will not become separated from the brush structure, as hereinafter set forth merc fully.

This invention also is directed toward a reversible brush.

The invention also is directed toward a brush, the shape of which may be readily changed so that the brush support instead of constituting substantially a straight line, may be arched for better operation.

The invention also is directed toward a brush of the aforesaid general character previously mentioned, and which is adapted to be readily provided with a handle to transform a handleless brush into a handle type brush.

The chief object of the invention is to provide a brush having the foregoing characteristics and which brush is suitable for the purposes before mentioned.

One chief feature of the invention consists in the flexible flange upon the tip whereby upon withdrawal movement of the brush with the tip, the flange turns back upon itself and lies along the tubular portion of the tip so that the full force of withdrawal is not directly applied to the tip for separation of the same from its support, the brush core or body, but the majority of the withdrawal force or opposition to withdrawal is absorbed in the bending of the flange and only a minor portion of that force is transmitted to the tubular portion and this portion is insufficiently effective toward the tendency to separate the entire tip from the brush body support.

The full nature of the invention will be understood from the accompanying drawing and the following description and claims:

In the drawing, Fig. 1 is a side elevation of a non-reversible type of brush provided with a protective tip.

Fig. 2 is a side elevation of a reversible type of brush, the dotted lines therein representing a detachable handle that has been applied to one end of the brush.

Fig. 3 is an enlarged central sectional view through the tipped end of a brush.

Fig. 4 is a perspective View of the tip.

In the drawing, 10 indicates a substantially cylindrical bristle body supported by a pair of twisted wire portions 11, the bristles being arranged in spiral layer formation. The numeral 12 indicates the tapered spiraled layer'portion of the brush which terminates in a projecting wire portion 13 see Fig. 3and the same constitutes in effect a screw thread arrangement adaptedto be seated or screwed into a recess 14 of a rubber cap having the end 15, the tubular portion 16 and the flange portion 17 adjacent the mouth of the opening in portion 16. In Fig. 3, as shown clearly, the flange on the tip is seated on the projecting end 13 of the wire portions 11 and to such a depth that the bristles 18 at the end of the brush are compressed and turned back toward the cylindrical portion of the brush.

' In the, form of the invention shown in Fig. 1, there also is mountedupon the projecting ends of the wire portions 11 a flange or guard disc 19 which, in the present instance, may be fibre, and the handle 20 includes a bore 21 therein which receives the projecting wire portion ends 22. One of the wire portions is extended, in the present instance, to the end of the brush and is turned outwardly and is seated in a slot 23 and 24, so that the end 25 and the lateral portion 26. seat respectively in the slotted portion 24 and 23see Fig. l. The aforesaid constitutes the single brush construction embodying the invention.

In Fig. 2 there is illustrated a modified and preferred form of the invention and herein the brush is of the reversible type. The cylindrical body 'of the brush is indicated by the numeral and the bristle support consists of two twisted relatively rigid wire portions 31. The cylindrical body portion 30 of the brush is extended as tapered portions 32 and 33 at opposite ends and each terminate short of the extreme ends of the wire portion 31 and upon the latter at 35 and 36 is mounted in substantially the same manner as illustrated in Fig. 3, the protective tip shown in perspective in Fig. 4. The same bristle and flange cooperation exists. The tip in all instances is prefer- 5 being arranged or mounted by said wire portions in spiral formation, which is old in the industry. The brush shown inFig. 2 has been forcibly deformed so that it may be readily applied to the spaces'between the spokes at the junction of the i0 spokes with the hub in a wheel construction and in such other places as cannot be readily cleaned by a sponge or standard brush construction.

Whenever it is desired to use'a handle brush arrangement with the brush shown in Fig. 2, all

that is necessary is to take a 6 to 8" piece of or rubber hose, indicated at 37, and by the dotted lines in Fig. 2, and having the bore 38,'and telescope the same over one end of the brush. Such telescopic movement continues until the hose assumes the position on the brush as indicated by the transverse line 39. This provides a detachable handle for the reversible brush and the brush will function with this handle in exactly the same' manner as the brush shown in Fig. 1. To separate the hose from the brush, the two are caused to rotate relatively of each other accompanied by a withdrawal movement, which enacts with the radially extending bristles to release them from looking engagement with the interior of the hose. Any other suitable tubular handle'or a handle having a bore, may be utilized. In thiscohnection, however, it is noted that the flange of the tip 36' constitutes a support for the end bristles in approximately the same manner that the flange 3 l9 constitutes a support for the end bristles in the form of the invention shown in Fig. 1.

While the invention has been described in great detail in the foregoing specification, the same is to be considered as illustrative and not restrictive g in character and the modifications disclosed hereinbefore as well as others which will readily suggest themselves to persons skilled in this art, are all considered to be within the broad scope of a the invention, reference being had to the appended claims.

The invention claimed is V 1. In a brush construction, a brush body comprising bristles circularly and longitudinally arranged, one end of the body having bristles of 593 shorter length than the body portion to form a tapered end, a pair of twisted wire portions constituting the support for said bristles and pro' jecting at each end beyond the brush body, and a rubber tip having an elongated body of lesser diameter than the tapered end and having a bore therein to nest therein the projecting twisted wire portions adjacent the tapered end, the projecting twisted wire portions at one end consti-' tuting a threaded connection and the nection anchorage for the tip.

2. In a brush construction, a brush body comprising bristles circularly and longitudinally arranged, one end of the body having bristles of shorter length than the body portion to form a tapered end, a pair of twisted wire portions constituting the support for said bristles and projecting at each end beyond the brush body, and a rubber tip of lesser diameter than the tapered end and having a single bore therein with a single opening and secured to the projecting wire portions adjacent the tapered end, the projecting wire portions at one end constituting a threaded connection for the tip, said tip including a lateral flexible flange projecting therefrom sole conadjacent the opening and bearing against the endbristles for mutual reenforcement and bristle protection in brush withdrawal movement.
