Application October 29, nniseisl No. 706,404 r I 1 Claim. (01. "15 -171) This invention relates to brushesof the paint brush type, and more-particularly to brushes of the paint brush type of the general character disclosed in my application Serial No, 560,763, n wl ten N 2,508 3 M y 23, 9

- In myabove mentioned pending application:

I described a new type of brush construction comprising a combined bristle and handle securing unit which was designed particularly for use with plastic handles. I Iv I I I have now found that by using an improved type of combined bristle and handle securing unit employing a new type of bristle securing element,;it is possible to considerably simplify the construction of this type of brush and I have further found that when using sucha modified type of combined bristle and handle securing unit it is possible where necessary to use wood or other non-mouldable substance as a handle material instead of, plastic, and yet retain the inherent advantages of the type of brush described in my above mentioned pending application. I It is the object of my invention to provide an improved brush construction of the type described in my Patent No. 2,508,931, which is simplified in construction. a I I I It is another object of my invention to provide abrush of thiskind in which" wood may be used for a handle material without detracting materially from the advantagesof .brushe'si made according to my above mentioned'pending appliationI V c. It'fis a f "the'r object of my inventionto 'pro-' videffa "sim iegeonvem nt methodfof securing aflwoodenbrush handle without any"visible nails or ivets, insucha manner that the handle is secured againstany tendency to warp,,twist out of alignmentor pullaway.

With these. and other objectsfin view the inifntion generally' comprises a combined bristle and handle securing unit including a ferrule into' which the butt ends of the bristles may be projected'," a bristle securing element having a substantially fiatapertured abutting surface for the butt ends of the bristles and fitted within the ferrule, a cementitious material penetrating the bristles, and flowing through and around the edges of the apertures in the bristlesecuring element and holding the bristles solidly in position, a handle seating element abutting against the bristle securing element within the ferrule, means for securing a handle on the handle seatingelement, and means in connection with the ferrule for jointly securingthe ferrule, bristle securing element and handle seating element together.

to provide a peripheral socket for the wooden handle, and to accommodate the handlese'cuf-- mg means. I One embodiment of my invention is illustrated by the accompanying drawings in which, I

Fig; l is a'fragmentary longitudinal section of' 'a paint type brush according to my inven- I Fig. 2 is a fragmentary longitudinal section of the same brush taken at right angles to the section in Fig. 1;

Fig. 3 is an enlarged fragmentary perspective view of the bristle securing element;

Fig. 4 is an enlarged fragmentary perspective view of the handle seating element. f Referring more particularly to the drawings,

A indicates generally a brush of the paint brush type constructed'according to my invention:

B indicates the bristles or flag of the'brush which may be of'any type desired.

C indicates "generally a combined bristle and handle securing element according to the inven' I flange I8. I The ferrule at its normally upper endv is offset outwardly and enlarged as at 19 so that? Theihandlesecuring element is specially sn against the bristle securing element I I, within the ferrule ll 0.

The bristle securing element I l is formedwith a' fiat apertured surface I3 which contains a1 number of :holes'i l; When assembled, the sur face'jl3 provides an abutment for the butt ends of the bristles B, and cementitious material which penetrates the bristles, and the holes It in the bristle securing unit I 1 forms a'body roughly in;- dicated by 16 in Figs. 1 and 2, which embraces boththe bristles and the bristle securing element, holding them firmly and positivelyto' gether. c j

' The" bristle securing element is further formed with afperipheral wall H, the free extremity, of which is formed into a peripherally ext nding the peripheral flange l8 ofthe bristle securing element ll may; whenthe element is, sli'dably projected into the ferrule It], be disposed within the confines of the ferrule. The handle securing element I2 is formed at its normally lower end with 'a'peripheral flange 20 which is designed to be slid into the enlarged end of the ferrule and into abutment with the "flange-' 'of the-bristle securin element. Thus, by, spinning 4 hating the necessity of visible nails, rivets, or the like for securing the handle. The elimination of nails or rivets produces an improvement in appearance which is an advantage. Of perhaps greater importance are two further advantages. On the one hand, nails, or. rivets, as in the first instance, tend to make splits in itheibristles resiiltingin a'brush" fingering during use." On the other hand, such nails or rivets are apt, in many IO-cases, to cut the bristles off in the path of the end of the handle D,and forma'socliettherfor.

I5'advantages of this kind are completely elimi- Extending from the ferrule-like extension 23 in the opposite direction is a peripheralhidelwall 24 terminating in the outwardly extending peripheral flange 20. V

In assembling the brushithe butts of the bristles a-ma be inserted within the ferrule it and including a "suitable 'sp'acer or Wedge where "d esirecLand the bristle securing element "Histhen prdjected into the" "open end' of the ferrule until the abuttingsur'face l3 ehgagesthe butts of the bristles B. A suitable cementisthen poured' into the open'en'd' oftheierruleso that 'it will pass through the openings l4 and into the butts of the bristles, and; "asindicated at E6, wilhpartially inib'ed'the bristle securingelement so that the bristles and said latter element are firnilyiocked together. v

The handle D may be attached "to the handle seating element I2 "by suitable securin means such as longitudinally disposed screws 25 which holdfthe .handle firmly in the socket "formed by the" peripheral "ferruie like extension 23 and the surface 2 l. v

Itis but asimple operationto,prdjectthehandle seating element "with its 'attach'edhandte into the open end of the ferrule lfl *untilthe flanges of'the bristle securing element l'andilhandle' seating element are in 'abutment'with one ,another, whereupon "the enlargedportion "of thefer'rule EH1 is suitably clinched such as byspinning orrulling fit around the dualjlprojecting flanges "f8 and 211' I'form'ed respectively on these elements. In consequence, thereforethe three elements, name ly; the ferrule I D, "the bristle securing element I l, and the handle securing element [2, are "locked together as aninseparable rigid unittoproduice a substantially unitary-brushmember which incorporatesasolidly attached handle. Alternatively, in securing the bristles within the -ferrule HI, the latter may'be slipped over Ithe bristles Lan'd 'the"'iiag end or the bristles' may be 55 dipped in a suitable adhesive which "will temporarily 'set'ithem. "The ferrule may then be slipped down on the .s'tiifen'ed bristles" and the thenuprojecting butt endsof the 'bristlesmay'be dipped in a suitable cement up to adesire'd level.

This methodvprovides for a uniform infiltrationiof 'I'iiefbristl'e siecuring' ler'nent I (may then be inserted' and' cement" poured in thefiopen' {end of thelferruletothe desired level.

Likewise, the nailed handles sometimes split as the nails'are passed through them, and serious dis- ;natetl-r'accordingitodzhe present invention.

Finally, several further advantages are produced." In one instance,-the necessity for a relatively deep penetration of the bristle butts into set firmly-without the necessity ofdeep penetration} and a suitable overall depth ibrthe' bristle settingcompound'and-woodenhandle. This-permits the use-of shorter' bristles obtained a't'fa 25 lower 'cost while maintaining "a =flne-' qualityof brush, which is of-particular importance -in the use -"of ,nylon'bristle. "Moreover, 'the shortening of the depth of the 'ferrule' permits the hand o'f the operator to be nearer to the bristles; "which is an important factor-in -keeping 'a balance -an'd= in lessening the leverage that an '-'op'erater useinfapplyin'gpa'int.
