w W. m w E MW m M Uited States Patent 2,810,147 Patented Oct. 22, 1957 2,810,147 SECTIONALLY FORMED BRUSH AND THE LIKE Thomas E. Aman, Mobridge, S. Dak. Application August 5, 1955, Serial No. 526,703 2 Claims. (Cl. 15-202) This invention relates to hair brushes and more particularly has reference to a hair brush the bristle-supporting head of which is sectionally constituted, so as to permit separation of the component sections in such a manner as to facilitate cleaning of the brush. Although the description of the device will be directed mainly to application of the invention to hair brushes, the invention, as will be apparent, is applicable with equal facility to dog brushes, and any other type of brush.

Ordinarily, the cleaning of a hair brush is attended with some difiiculty, due to the fact that a separate brush is generally required for the purpose of cleaning the bristles. Alternatively, some type of separate cleaning means must be employed, and even so, a full, satisfactory cleaning of the brush head is diflicult, due to the relatively large area of the bristle-supporting surface thereof, making relatively inaccessible the central part of the bristle assembly.

In View of the above, the main object of the present invention is to provide a hair brush the head of which will be composed of detachably connected sections, with said sections being so designed as to permit the bristles of one section to be rubbed over the bristles of the other section, in a manner that will effect a swift and easy, and yet full cleaning of the bristles of both section's.

Another object of importance is to provide a device as stated in which themeans detachably connecting the sections will be so designed as to permit the connection or disconnection of the sections to be accomplished speedily and easily, and will at the same time be adapted to rigidly secure the sections to one another when the hair brush is in use.

A further object of importance is to form said connecting means in such a manner as to dispose the same completely out of the area in which the bristles are embedded in the head, so that there will be no interference with mounting the bristles in the head during manufacture of the brush.

A further object is to design the means connecting the sections together in such a manner as to cause the major portion of said brush to be wholly concealed from view within the body of the brush.

Yet another object is to provide connecting means for the sections of the hair brush which will compose a plurality of parallel pins on one of the sections, engageable in provided sockets of the other section, with said pins being disposed in relatively offset, horizontal planes so as to provide a particularly strong connection which will resist any pressures tending to flex one of the sections relative to the other.

A further object is to combine with the relative olfsetting of the pins a curved, contacting edge formation of the sections, resulting in positioning of the pins in an arcuate series, in such a manner as to cause the arcuate path in which the pins are disposed to cooperate with the offsetting of the pins in different planes in assuring a firm, tight connection between the sections of the brush.

Other objects will appear from the following description, the claims appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, and wherein:

Figure 1 is a top plan view of a hair brush formed according to the present invention;

Figure 2 is a side elevational View; and Figure 3 is a view similar to Figure l in which the sections have been separated from one another.

Designated generally at 10 is one of the sections of the hair brush, while designated generally at 12 is the cooperating section. The section 10 may be appropriately termed a handle section, while the section 12 is a head section. However, as will presently appear, the handle section includes a part of the head of the brush and the terms used are intended merely to facilitate identification of the respective sections during the following description. The sections may be formed of plastic, wood, or any other suitable material, and the handle section 10 includes a handle 14 integral at its inner end with a Wide base 16 having, as shown to particular advantage in Figure 3, an inwardly curved outer end surface 18.

Secured to the fiat underside of the base 16 are transversely spaced, short rows of bristles 20, there being in the illustrated example two tufts of bristles at each row, with the rows being disposed in an arcuate path closely paralleling the curved edge 18 as best shown in Figure 1.

Embedded at their inner ends in the curved end surface 18 of the base 16 are

pins

22, 24 of copper or other noncorrosive material. The pins are embedded in the base 16 for approximately half their lengths, and extend in parallel relation, said pins being spaced apart transversely of the base 16 over substantially the full width of the base. In the illustrated example, but not necessarily, four pins are employed, the middle pair of pins being designated at 24 and the pins of the outer pair being designated at 22. The middle part of pins lies in a horizontal plane lower than the horizontal plane in which the outer pair of pins 22 are disposed, as shown in Figure 2, and due to the fact that the end surface 18 is curved, said pins are disposed in an arcuate path, so that the pins 22 project outwardly a greater distance than do the pins 24, with the pins 24, conversely, having the inner ends of the projecting portions of the pins 22.

The section 12 is substantially greater in area than the base 16, and has side edges which constitute extensions of the sides of the base 16 when the sections are connected, as shown in particular advantage in Figure 1. Further, the top surfaces of the respective sections merge into one another, as do the flat bottom surfaces thereof when the sections are connected. Section 12 includes a-body 26, the inner end edge 28 of which is arcuately bowed outwardly, to mate with the inwardly bowed end edge 18 of the base 16, thus to provide a tight joint between the sections when the sections are connected.

Formed in the end surface 28 of the body 26 of the outer section 12 is a series of

cylindrical sockets

30, 32, the sockets 30 being adapted to receive the projecting portions of the pins 22 and the sockets 32 being adapted to similarly receive the projecting portions of the pins 24. The sockets 32 are disposed in a common horizontal plane lower than the common horizontal plane of-the sockets 30, in the same manner as the

pins

24, 22

respectively are disposed, and thus, when the sections are connected, they will be securely held against relative flexure in up-and-down directions, and also against relative movement laterally of one another.

Embedded in the bottom face of the body 26 is a plurality of tufts of bristles 34. These are arranged'in rows extending longitudinally of body 26, said rows being spaced uniformly across the full width of the body as shown in Figure l and being aligned with the rows of 34 are substantially longer than the rows of bristles 20, and accordingly, when the sections are detached from one another, the handle may be grasped, and the relativelyv small number of bristle tufts 20 can be rubbed againstv the bristles 34, and also between the rows of bristles 34, to effect a thorough cleaning of the section 12,. Thereafter, the section 12 can be grasped and the bristles thereof rubbed in the same manner between the rows of bristles 20, to effect a cleaning of the section 10, Of course, when the sections are being rubbed against one another, they serve to effect a simultaneous cleaning action of both sections as well, thus permitting the dean: ing of the brush to be carried out with maximum ease and in a minimum amount of time. 4 i i To latchably connect the sections to one another, there is provided a latch member 36, formed from a length of leaf spring material, secured by. longitudinally spaced rivets 38 to the body 26 and having a free end portion turned upwardly as at 4 and projecting beyond the end edge 28 of the body 26. An opening 42 is formed in the free end portion of the. latch member, and is adapted to receive a lug 44 projecting upwardly frornthe top surface of the base 16. Thus, when the

pins

22, 24 are engaged in the

sockets

30, 32 respectively, the lug 44 will cam upwardly the upwardly curved free end portion 40 of the spring latch, and when the sections are in full engagement with one another as in Figure 1, the lug will snap into the opening 42. This holds the

sections

10, 12. against relative movement in a longitudinal direction away from one another, while the brush is in use. V l i It will be apparent that, the brush, when in use, has the same form and functional characteristics as a con ventional hair brush not having the advantages previously described herein. At the same time, the brush can be readily separated so far as its component parts are concerned, and can be swiftly cleaned by using one'section for the purpose of cleaning the other section. Still further, the connecting means is, 'with the exception of the latch clement, wholly concealed, and is so designed as to insure to the maximum against relative deviation of the sections in any direction. 1

It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof 'described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claims.
