.3 Claims. (Cl. Yu-30) This invention yrelates to a roller type paint applicator and 4particularly to an improved handle construction therefor.

One of the `features of this invention is to provide a manipulating apparatus removably engageable with a hollow cylindrical `paint-applying portion of a roller type paint applicator with this apparatus comprising a handle portion Aand a core member rotatable 'thereon and insertable "within the cylinder portion, the .core member -inc'luding a vpair of spaced .collars and a segment of a cylinder extending therebetween with the segment ineluding end 4portions enclosed by the collars to hold the core lmember assembled and an outwardly-,extending spring edge portion 5located 'between but .spaced from the collars. Another feature of the invention is the provision of :such a vstructure Vwherein the core member includes a plurality of Alongitudinal segments of a .cylinder arranged seriatim to describe Asubstantially a cylinder with each end portion of a segment within a collar having an edge bearing against an edge ofthe next end portion, each `segment having an outwardly-extending spring :edge portion located 'between but vspaced from ,the collars with each end o'f a `spring edge -portion being defined Aby a deep notch `in 'the segment adjacent to a collar, each end portion of a segment within a collar being provided with a circumferential groove to 4give rigidity 'thereto and each segment being vprovided with a lSecond circumferential groove extending `from Jthe "bottom of a 4notch 'around the remainder ofthe segment substantially parallel to Ithe iirst groove 'and each `collar having an inturned inner edge engaging one of `these second grooves. l:A further feature of the invention iis the lprovision of a lmanipulating apparatus wherein the core member includes 'an outwardly-extending spring vmember having a sloped 'lateral Vedge vportion acting as an inclined Aplane vlever to aid'in Vforcing-the :spring mem ber inwardly when the edge of "the cylindrical :pai-ntapplying member is forced over this edge. 'Yet 'another feature of the invention ,is the provision of such a structure wherein Athe core member includes a pair of spaced collars and a plurality of longitudinal segments of a cylinder extending therebetween, .the ends of :the lsegments :being :enclosed by the collars without A,substantial Compression of the segments and `each :segment having an `outwardly extending spring edge portion located be- .ftvueen the collars. Other ffeatures Aand advantages zof .the invention will be apparent from .the following description `of one embodiment of the invention l as shown in :the accompanying drawings. Qf the drawings:

When :paint is .applied Eto a surface fby means v.of .la roller :applicator .fthe @applicator is Aordinarily `.Constr-,usted so that lthe absorbent :surface fof ethe roller fmay :be iat least 4partially saturated lwith :paint and then rolled-over the surface to 'be painted. The absorbent rollertis .ordinarily freely rotatable :on i-a :manipulating handle. As the paint absorbing roller eventually .becomes wenn and contaminated with v,dried `paint `tit is necessary that the roller be replaced -with :a :fresh `one. =ln the applicator of this invention `applicant has :provided 1a :structure wherein the `cylindrical roller yis firmly held tin place :0n the manipulating Vhandle .-by .fa spring act-ion but may tbe readily removed ,for 4-r-,eplaeement Vby `a new applicator. The core memberfof the manipulating handle apparatus Vis Aof sturdy .but inexpensive construction and ;is preferably made by Vinterlocking sheet -rnetajl :portions having .integral spring portions.

In the .embodiments shown in the `drawings V`the paint applicator comprises -a manipulating apparatus including a handle portion 10 and La tcore `member 11. The .core lmember .11 is `rotatable fon a .straight axle vport-ion 10a of the handle. ,As shown ,in the drawings, the :handle portion 17,0 fcomprises a imetal rodfof circular tcrossgsecftion bent to form the axle portion 10a with the end opposite the .axle yportion .being fitted "with a hand, fengageable'member d2.

The score Kmember 11 =s arranged vto `removably -:retain Vva hollow .cylindrical paint-applying .member .13. This ,member includes a rigid .cylindrical portion :13a having vfibers 13b on the y,outer surface thereof. Such `a paint- Yapplying roller is well known in 4the art. When -tlue applicator is used -to .spread paint on the surface, :the outer part of the fibrous portion 13b is immersed-in ,pa-inl .and ftp-lie roller fis then .rolled over vthe sunt-ace to be painted.

The ycore member 11 that .-is .removably retained vwithin the ,hollow roller 13 vcomprises a pair l.of substantially .cylindricalcollars 14 Irotatably mounted on vthe .axle i100 `and spaced apart .,a.distance substantially .corresponding VAto rthe .length of the paint-applying member .13. Each .of fthe collars f1.4 rhas `a `closed `inwardly `recessed end 14a attached .to a substantially cylindrical bearing :rotatable .on `:the `axle 510g, the bearing at the outer end of the .axle being .designated `as 15 `and that at the inner rend as 15a. The opposite'openiendof eachtcollar J14 :extends toward the other collar, .as ,shown in .Fig 3.

Held by the collars 14 are `a pair `of Vsubstantiaily semicylindrical ,sheet metal segments .16 which together substantiallydescr-ibe -a rcylinder. Each ofthe .segments 16 has van end located within la collar -1'4 with each end port-ion 16j being provided-wilma circumferential :groene 16a to reinforce dt ,against bending. Each :of :the tend portions within :a collar ,14 is provided vwith `an inwardly .directed flange Mb bearing against asimilar flange .on the adjacent section. Thus, .each Isemicylinrlrical section r'16 `has two substantially .fdiametrically fopposite iianges 1611 .each hearing against fa similar flange om the next `segment i6 Withfall :these .anges being located withinthe collars 14.

in order to lock the semicylindrical segments t6 :in place, each of the collars 14 s'providedraniinttwneti inner edge 14B engaging a corresponding groove 16e in the sheet metal segments 16. Thus the assembly of collars 14 and segments 16 are rigidly held by the edge portions 14b of the collars bearing inwardly against the segments 16 and the flanges 16b of the segments bearing against each other. The circumferential grooves 16a and 16e add rigidity to the structure.

Each segment 16 is provided with a spring portion 16d extending generally outwardly when uncontined, as shown nFig. 5. These spring portions are provided by cutting generally V-shaped notches 16e from one edge of a segment 16 with each notch being located adjacent an'end portion 161 Ithat is held within a collar 14. The bottom of the deep notch 16e is located at approximately thc midpoint of a segment 16 and is positioned at the end of the inwardly directed groove 16C that is positioned in the uncut portion of thesegment adjacent an end portion 16f to give rigidity to the structure. Thus, the groove 16a within'the collar 14 and the groove 16e just outside the collar 14 aids in providing a rigid construction at each end of the core member. Y Y

The spring portion 16d, defined by the part of each segment 16 between the V-shaped notches 16e, is distorted outwardly as shown in Fig. 5 to extend beyond the cylinder defined by the undistorted portions of the segments 16. When the core member is inserted within the tubular portion 13a of the roller 13Kthese spring portions 16d bearV against the inner surface of the tubular portion '13a and hold the roller 13 on the handle 1li. When the paint-applying roller is removed from the handle it is necessary only to grasp the roller and force it to the left, as viewed in Figs. l and 3. When a new roller is applied, it is pressed on in the reverse direction. The sloped inner edge of each groove 16e aids in pressing the roller into place as this edge acts as an inclined plane to produce leverage on each spring portion 16d and force it inwardly when the leading edge of the roller is forced across the edge 16e.

In order to hold the core member properly located on the handle portion the innermost bearing 15a bears against a backing member 17 fastened to the axle 10a. `The opposite bearing member is held in place by an outwardly located washer 18 held on the end of the axle '10a by aV screw 19. When it is necessary to remove the core member 11 the screw 19 and washer 18 may be removed and the core member slipped oft the end of the axle.

i Asv can be seen from-the drawings, the cylindrical portions of the collars 14 do not compress the segments 16. TheV parts are held in assembled relationship primarily by inwardly-extending inner flanges 14h on the collars engaging the grooves 16C. This lack of initial compression of the parts is of decided advantage in providing a superior applicator. These advantages include ease -of assembly as the parts may be made with greater toler- Iances andthere is no need Vto compress carefully and ilaboriously each cylindrical segment to lit it carefully within the collars. This avoidance of initial compression Aalsoresults in longer life of the applicator as there is no necessity for repeatedly bending outwardly the resilient edges of the segments in order that the required pressure will be maintained at all times against the inner surface of the cylinder 13. As the new applicator avoids initial compression of the parts there is also less danger of the cylindrical segments assuming a permanent set which is liable to occur when the parts are constantly under compression. par-ts are made of thin sheet metal members that are more susceptible to permanent set.

Having described my invention as related to the embodiment shown in the accompanying drawings it is my intention that -the invention be not limited by the details of description unless otherwise specified but rather be construed broadly within its spirit and scope as set out in the accompanying claims.
