Application. January 26, 1946-, Serial No. 643,643'

2 Claims. 1

This invention. relates tcimprovements in brushesand it has reference more particularly to novel features in the, construction of paint brushes; it being the principal object of this invention to providejbrush heads made in laminations and which may be interchangeably used in the same brush handle, and which heads may be made up of various number of 'brush head sections or laminations as required or desired for any particular use.

It is also anobjectof this :invention to provide brush head laminations that may be assembled in various numbers in an interlocked relationship and applied within*v the clamping jaws ofthe handie portion; the jaws ybeing adjustable to receive and hold brush headsof one` or more laminations.

Still anotherobject ofV the invention is to Aprovide an irnprovedtypeY ofbrush handle including a pair of jawsthat are arrangedto holda brush head between themV andy are adjustable by means of a nut located atthe outer enclfof the handle.

Still another object of the invention is to pro,- vide aA brush that permits quickA and. easy removal of a brush head therefrom and the separation of the laminations making up the head for quick and eiective cleaning of the bristles.

Still further objects of the invention reside in the details of construction of parts; in their relationship and mode of operation as will hereinafter be fully described.

In accomplishing these and other objects of the invention, I have provided the improved dedetails of construction, the preferred forms of which are illustrated in the accompanying drawings, whereini Fig. 1 is a side view of a brush embodying the novel features of the present invention.

Fig. 2 is a longitudinal, sectional View of the same, showing the brush handle jaws opened apart for reception of or removal of the brush head.

Fig. 3 is a perspective View of a single section or lamination used in making up a brush head.

Fig. 4 is an end View of a brush head comprising two assembled laminations.

Referring more in detail to the drawing-d The present brush comprises a metal handle portion and a. brush head portion. The handle is designated generally in Fig. 1 by reference character H and the brush head by reference character B. The brush head may comprise one or more similarly made brush sections or laminations I0, one of which is shown in Fig. 3 as comprising a pack of bristles I2 with upper ends bound by an enclosing metal band I3. Each section,4 or lamination, of .the brush would beto-i .the full width Aci thexbrush head, but-relatively thin; as. ,illustrated and.: itis the: intent. that ,such laminationsbe Aassembled.face te; face., as seen `in Fig. ;2',..and used- VVin any reduired number to ,make up a. brushheadlof Varequired-,thieleness for the Work being done.

.In order. thatthese laminationsinay `be held in an exact .and proper relationshinwhen saassemhled,. I have provided :the bndingstrp .l'3 at each sidecf the section .or lamina-tien with al1-.indenture,.-as at .la andi ,aprotnberarnce or Yboss as 4at i6; these being oppositely arrangedionaopposite sides or" rthe section.7 In the assembling of vthe laminations, 4face to face the nrotuberances I6 ,willl seat within the indentures I5 of the other aand .theseare so arranged: thatthe,sections-will thereby Ibe held irl-.an exactregistraiton as understood by reference .to Fig, 4..

It is further to be understood that brush heads .may be made nn.otone,.two, ,three yor more 1aminations.

The handle portion of the brush .Qomprisesthe `opposite side sections Ztl-2.9;, alikein shape yand ot the same'size. lAtther rupper ends ythese-sections are joined by a resilient cross piece ZI in spaced relationship. The lower end portions of the opposite side sections 20--20 are spaced apart and served as jaws to receive and hold the brush Y head between them.

The opposite side sections of the handle have flat, and somewhat widened, jaw portions 22 at their lower ends, designed to embrace the brush head between them, and each of these jaw p0rtions is formed with an indenture 25 and a boss 26 at the same spacing as those of the brush head sections. Therefore, when the brush head is assembled, and its upper end portion placed between the jaws 22-22, these parts may be clamped together to grip the head therebetween, and in so doing, the protuberances It of the outside laminations of the brush head will be seated in the recesses 25 of the brush head and their indentures I 5 will receive the jaw protuberances so that the head will be held secure.

The clamping action of the handle sections is eilected by means best shown in Fig. 2, wherein it is noted that a rod 30 is located lengthwise of and between the opposite side sections of the handle. At its upper end, this rod passes through a centrally located hole SI in the piece 2| and is equipped at its top end with a turning button 32. The lower end portion of the rod is threaded, as at 33, and is adjustable within a tubular extension 34 which, at its lower end, has an extension 35 xed therein, and pivoted in the lower end of this extension member are toggle levers or links 36-36 that are in the crank shaft form shown in Fig. 1, with crank ends pivoted on the handle jaw portions. The arrangement of parts is such that when the rod 3U is turned in one direction by means of the button 32, the toggle linkage wil be expanded and the jaw spread apart. Then when turned in the other direction, the toggle will be retracted and the jaws will be drawn together and thereby clamped against the brush head to hold it in place. Adjustments may be quickly and easily made and brushes of one or more laminations used and held securely in place between the jaws.

One advantage in this brush construction resides in the provision for separation of laminations for easy and quick cleaning of the brush and handle. Another advantage is the possibility of making up brushes of dierent weight or thickness to meet the job at hand. Still another advantage is the requirement of only one handle for any number of brush combinations. The inter-engaging of the protuberances of the laminations with the indentures provides for secure holding of the laminations in the handle so long Aas the jaws are clamped, but easy separation for cleaning when unclamped.

While in the foregoing description and in the drawings I have described and shown a brush head of one width only, it is to be understood that the brush head may be made in Various widths, as has been indicated in the dotted line shown in Fig. 1.

Furthermore, it is to be understood that by the assembling of laminations of varying widths a brush head may be built up of a, substantially oval shape; that is. by using wider laminations in the central portions of the brush head and narrower laminations toward the outside of the 40 brush head.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent is: l. A paint brush comprising a, brush head made up of a plurality of independent bristle sections,

each equipped with a metal binding about one end, and said bindings of adjacent sections being disposed in face to face relationship and with parts of bindings of adjacent sections interengaged and a handle comprising coextensive opposite side portions serving as oppositely related gripping jaws at corresponding ends for receiving the brush head between them and joined at their outer ends in a manner to permit the jaw portions to be moved from and toward each other and a toggle linkage between and connecting the jaw portions of the handle and an adjusting shaft for the toggle disposed longitudinally within the handle and extending beyond the joined ends thereof and operable to adjust the said side portions of the handle to move the jaws from and into gripping contact with the brush head when placed between them.

2. A device as in claim l wherein said adjusting shaft includes a tubular inner section attached to the toggle linkage and an outer end section rotatably held against longitudinal movement in the handle and threaded into the tubular section and equipped at its outer end with a turning button.
