PAINTBRUSH HAVING A PLURALITY OF DETACHABLE TUFT SECTIONS Filed March 21, 1946 Patented Dec. 6, 1949 PMNT-BRUSH G A PLURABITYGF DETACHABLE TUF! SECTIONS a Paul S. Ricchiuti, Chicago, Ill. I Application MarchZl, 1946,5Se1ialNon65'55942- 1 This mvention relates to a new and improved sectional .paint brush and 51135 .for one of .its principal :objects the provision pf a unit bristle section adapted to be used either singly or in combination with a plurality of emits to form various sizes of brushes.

important object aof this invention is :to provide a rectangularly shaped bristle section adapted to be removable attached to a handle and depending clamping skirt.

Another important object -.of this invention :is.

to provide a removable and replaceable :bristle section for a paint brush thereby facilitating the cleaning of the bristles atter use and/or .i'ephic-v ingthe clean bristle section or inserting :a new bristle section should the original bristles :become worn. i

A- further important/object of the invention is the provision of a paint brush having clampin ferrule members :s'haped substantially rectangular and adapted to clamp a rectangular set of brush bristles whether the bristles comprise a single unit or a composite group of unit sections arranged "to form a large rectangular shape.

.A still further important object @of the inven tion is to provide a paintbrush having a :permanent handle and ferrule portion and replaceable bristle sections to facilitate use of the brush bristles in various sizes of :handle shOldBllS, thus effecting a more economical use of the several paintbrush elements.

Other and further important objects will Ebecome apparent from the disclosures in the following specification and accompanying drawings, in which:

Figure 1 is a perspective view of a paint brush incorporating the principles of this invention;

Figure 2 is an exploded view of the paint brush as shown in Figure 1;

Figure 3 is a sectional view taken on the line 3-3 of Figure 1;

Figure 4 is a perspective view of another paint brush incorporatin the principles of this invention; and

Figure 5 is a perspective view detail of the unit brush section employed in the brushes of Figures 1 and 4.

As shown in the drawings the reference numeral I0 indicates generally a paint brush handle 1 Claim. (01. 202) for :relativehzmermanent The handle in cludes a hand-engaging portion .11 and a wide spread portion :12 having :a downwardly dependin tongue 113, as best shown in Figure 2, which telescopes within the twoemiece ferrule member 14.. v

The two-piece .fenrule imember consists of op nosed plampmg skirt'zmemhers 1.5 and It. Each skirt member l5 and i i is equipped with a rela--:

tive'ly vertical side wall H and inwardly turned ends i8 and 4:9; Additionally the opposed skirts 5.5 and :kfizhave zzrlined apertures 12s and 2!. Dire downwardly depending tongue 1123 of the paintbrush handle it iisilikewise equipped with apertures 32,2 spaced similarly to the apertures '20 and 2i and in a'linement therewith the brush handle inoperative position with respect to the two-:piece iernule Ill. :Scnews comprising :an in-.

ternally threaded sleeve member :23 and :an .ex-

ternally threaded member :24 are positioned. through :a-iined apertures 20, 2 l., and '22 land by. screwing the members together the opposed skirtmembers is and dtli are drawn up closely to the brushhandle in. 1 s The brush ibristlesili :as shown in Figure :1

appear 11:0 be a :single bristle section. However, as shown in Figure 2 the bristles 25 comprise an aggregation :of six rectangular .unit .bristle sections .26. Each unit bristle section :26 is complete inlitsel'f. The iu-m't is equipped with a head 2;! carrying/or supporting numerous downwardly depending zbristles which cover substantially the entire under surface of :the rectangular head- 21. These heads may be made of any suitable material such as rubber or the like or metal jacketed rubber which performs the important function of maintaining the bristles fixed with respect to the head portion. The rectangular shape of each unit bristle section is quite important insofar as this invention is concerned. When several bristle sections are gathered together, the result is a new size brush. The resultant rectangular shape is such as is generally used for paint brushes. The clamping ferrule operates quite effectively on a rectangular shape, and further the rectangular unit sections prevent any dead or corner spaces where there are no bristles.

Inwardly turned flange or clamping members 28 on the ferrule 14 grip against the bristles beneath the head portion 21 of the unit sections 26 and positively maintain the bristle unit or units in a mixed. position with respect to the handle and Ierrule lo and 14, respectively. The unit sections 26 of the brush cannot now be removed from the handle until such time as the screws 24 are disen a ed or at least loosened.

The aint brush in Figure 4 shows a brush having a single bristle unit, but otherwise the handle 29, clamping ierrule 3D, and bristles 3| are identical. Figure shows a bristle unit 26 having the head 21 and downwardly depending bristles over the full under surface of the head. This bristle unit 2o" comprises the entire bristle section 3| of the brush as shown in Figure 4 or comprises one-sixth part of the bristle portion 25 of the large brush as shown in Figure 1.

The sectional paint brush of this invention is very easy and economical to manufacture. The individual parts are simply constructed and are conducive to long wear. As an example of this,

it should be pointed out that the clamping flange six sections such as shown in Figures 1 and 2 or for that matter the number of unit bristle sections employed may be unlimited in number in creating the desired size brush. The handles and the ierrules may be used over and over again, and when the unit bristle sections wear down, new sections may be purchased and installed within the two-piece ferrules as shown at It or 39. The ferrule is made in two pieces in order that they may be drawn together to efiect a clamping of the unit bristle sections therewithin.

It will be understood that the purpose of this invention is to provide a set of unit bristles for point brushes which the user may assemble into any one of several sizes or handles by combining one or more sections of bristles with one or several sizes of handles to make the desired size of brush. The assembled brush can also be easily and quickly dismantled for thorough 28 on the ferrule members in addition to prevent- 9 ing withdrawal of the bristle units when the brush is assembled adds considerable strength and rigidity to the ferrules. All of the parts of the brush are easily removable and a cleaning after each usage contributes to longer effective use of the paint brush.

The brush of this invention has been designed to overcome the inadequacies of presently manuiactured paint brushes. Heretofore, paint brushes, at least those used by amateurs or just occasional users, were items to be purchased for each new job. The paint brush would be used and an attempt would be made to clean the bristles after use by swishing the bristle portion of the brush in a paint thinner or remover such as turpentine. In the case of large brushes, however, and necessarily more costly brushes, it seemed practically impossible to remove the paint from the inner bristles to which the paint adhered. Others have attempted to solve the problem of cleaning paint brush bristles but none of them have employed a small unit rectangular bristle section which may be used as a full unit for a small brush and which may be removed from the handle and completely immersed in turpentine or the like without detriment to the brush portion. Further this unit bristle section may be used in combination with-other unit bristle sections to form larger brushes of any desired size. In all cases, however, the unit bristle sections are of a fixed standard size and may be used interchangeably so that as a userdesires he may buy only a half dozen bristle sections and by using several different size handles may have the use of several sizes of brushes such as a one section brush, a two section brush, and any number all the way up to the cleansing so that the brush may be put away for future use without becoming hard and unusable. Further the cleaned unit sections may be immediately used in another size handle for continued painting operations.

Numerous details of construction may be varied throughout a wide range without departing from the principles disclosed herein, and I therefore do not propose limiting the patent granted hereon otherwise than as necessitated by the appended claim.

What is claimed is: w

A paint brush having a plurality of unit rectangular bristle sections placed adjacent each other in both lateral and longitudinal directions and forming a composite rectangular bristle portion, a skirt encircling and substantially enclosing the plurality of unit rectangular bristle sections, and means for tightening and loosening said skirt for assembly, removal, or replacement of any one or all of the bristle sections, said skirt having an inwardly turned lower edge engaging substantially the entire periphery of the composite rectangular bristle portion.
