f1 UNITED [STAT ES PATENT; OFFICE 1 1 g 2,477,234 FINISHING L 'eo Eai f j U J. Anson Brock, South Duxbury, and Robert I Brock, I Abington, Mass., assignors I to; zBI'OQlk Chemical Co; -Inc., North Abington," ,Massl,",a corporation of Massachusetts ,3 Ourpresent invention a'novel and improved finishing roll cover adaptedparticularly for wax and stain-applyin rolls or wheels.

Heretofore, finishing or polishin rolls for various purposes have usually been made in the form of a roll or wheel with a series of brush-like bristles over which a cover of canvas, drilling, or other textile material was applied. v'Io such covers, the wax, stain, or other finishing andpolishingimaterials-were applied, and the wheels or rolls being rotated atv considerable speed effected the smoothing, polishing-and finishing operations onthe article being treated.

Suchi finishing devices have been extensively used in the shoe trade, and the use of prior cotton or textile material for the cover resulted in wearing out-the same very rapidly so that cone stant renewal of the covers-was required, Also, morerecently a cover made of nylonmaterial has been-used, but, such nylon resulted in wearing out the brush'underneath the cover, and also such'nylon material permitted slippage between the cover and the brush because of lack of friction between the contacting: surfaces of the brush with the'nylon material. Such slippage tended also'to wear out the brush and; furthermore, the nylon fabric permitted the wax and finish to permeate .and go thru the cover-and onto the:brush, resulting in causing the brush.elements to become-stilt and saturated with wax, nullifying-the resiliency'of the .brush as well-as increasing the slippage-. G

'Wehave discovered that'the combination of a cotton textile layer for direct contact with the brush element'o'n the roll or wheel, together with a nylon polishing layer for contact/with the article being finished, causes new and novel results in the finishing operation as well as insuring longer life and'usefulness in the'burnishing roll. Such a combination, with the nylon material on the outer surface, backed by the cotton material underneath the same and in direct contact with the roll, gives greater wear resistance to the polishing-nylon surface, together with greater protection and increased friction between the cotton :cover and the brush, as Well as enabling the waxor other finishing material which penetrates the nylon to be caught and held by the underneath cotton layer, protecting the brush from becoming wax-filled and, hence, hard and nonresilient, and resulting also in a carrying of the wax between the nylon and cotton layers, thereby enabling the wax thus carried to be fed back thru the nylon surface onto the work.-

Thus, our present invention insures a longer Wearing of the brush, maintains the desired friction between the cover and the brush, preventing slipping; causing the wax ,or finishing material to be carried by the cover and spread moreevenly, and feeding out the polishing material thru the I Application May 22, 1947', Serial No. 749,704 5 1i I v1 Claim. (01.12 495) 5 I, nylon surface, which nylon surface itself is more wear-resistant becauseofthe backingand padding effect afforded by the cotton cover.

A further advantage of our'combinlng a nylon layer and a cotton layer, as described for a finishing cover, consistsiinpreservingthenylon and preventing it from being chafed,.,torn, or worn, particularly, durin the finishing operation" on shoe soles, heels, and heel breasts. Thus, the cotton :layer protects the nylon in its. wear on 'the work and also protects, the;brush,;while the nylon surface takes up thedirect wearon the. work and protects the cotton layer, and bothlayerscooper-' ate in; holding wax :or the likematerial therebetween and insures more even distribution of the same on the work, which mutual interrelation between the two layers gives longer-life .to both thei-brush-andthecoverand saves the time of changing worn covers as well as changing the brnsh-,- rolls or wheels, t 1 i The-advantages of this two-layer combination will be "appreciated when it is, considered that heretofore: singlet-layer covers were worn and changed for every six or eight casesof shoes; Whereas With our novel combination, with the cotton under layer and the nylon upper layer, our improved cover will operatesuccessfully on from fiftyto one hundred cases of shoes. 7 s

We have-discovered, also, that our combination of cotton and nylon-layers on finishing wheels ef fects a vast saving in the wax or finishing material utilized, as-well as a savin in the time and labor of applying the wax, which wax has to be intermittently'applied; I

'We may-prefer, if desired, to spray theinner surface of the cotton layer with a coating of latex, or the like, which will thus be in direct contact with the brush, thereby increasing the friction and tendingto, prevent undue wear on the cotton layer.- v ,7 g,

By our combinationof difieling materials, each layer ideally positioned; for the usefulness for Which it is intended in the finishing wheel operation, wax canzbe applied sufficiently so that a substantial amount iscarriedbetweenthe two layers and then fedback lthru the more porous nylon layer directlyonto the work. The more uniiorm application of. the finishes. being used also results in a better quality of work and increased speed in the polishing and finishing oper: ation.

vlildditional features of our present invention are the way in-rwhichthetwo'layers are united, ar fording, a considerable free area for carryin wax between the two; layers. .sFor this .purpose we unite the two layers While fiat by a stitching operation along the marginal portion of the nylon and cotton' strips, preferably'turning over and stitching the edges of one or both layers to prevent unraveling ,of the-materialand to provide a hem in the lower cotton layer thru which purse or running ,stringsorcords are led 'toadlust' the cover to the brush and partially enclose the periphery of the brush to which the cover is applied.

While we prefer to unite the two layers before they are applied to the finishing mil, itis within the scope of our present invention to utilize the combination of two layerswhether at tached or unattached as long-as they are assembled in association with the finishing "roll to which both are applied, the cotton layer being underneath and in contact withfthe finishin brush, and the nylon layer being on the outside for contact with the work.

Referring to the drawings:

Fig. 7 isa cross-sectional viewon the line 1-1 of Fig. 5, and a Fig. -8 is a cross-sectional view on the line -8--8 of Fig. 2.

Referring to the drawings, Fig. l designates a usual standard type of finishing roll comprising a core 1 having a central opening 2 therethru to fit upon a shaft anda massof bristles 3. Our improved cover is applied to this typeof finishing roll, or to any other, but a finishing roll with the mass of bristles gives desired -=resiliency and is generally employed, particularly in the shoe trade, and to which typeof roller our improved cover is especially advantageous.

Our cover comprises two layers as shown in Figs. 1, '2 and 3, the lower layer 5 beingof cotton or other suitable textile material relativelyclosely woven, which layer is providedwith stitched marginal edges, as indicated at 6-6, by=stltching I, Fig. 8, thru which drawstrings III-40 are'threaded to attach the cover about'the finishing rolls including the mass of'bristles. This cover 5 is made as an endless band of suitable length and width to be enclosed about theroll for which it is designed and to be snugly drawn thereabout by tightening up'the drawstrings111 on each side, which are tied in a suitable knot, as shown in Fig. 1. 7

Our outer or nylon cover is illustrated at it being preferably of slightly less width thanthat of the textile layer 5, the two layers being prefer-- ably stitched together as shown in dotted lines at 14, Fig. 2. This outer nylon cover is ofsuitable length and of substantial width to fully cover the mass of bristles 3 and to be held in assent bled position by the drawing of the running strings 10. Preferably, we have the meeting edges of the nylon strip turned-over, as indicated at l5, and extending under the meeting edges of the two layers, being held bystitc'hing 18 to prevent a frayed edge, as clearlyshown in Figs. 2 and3.

As shown inFigs. -4, 5, '6, and 'l, we may employ two separate layers, each separately attached tothe finishing roll and each of 'suflicient' width 4 and of appropriate length to cover and enclose the mass of bristles 3. this f0rm;1the; underneath layer 5 is formed with the running strings H1 and is first applied to the finishing roll and the running strings I ll drawn tightly, pursing the stitches of the cover about the roll and held in assembled position by knotting the ends, as

shown. 'Therenpon, a separate nylon layer, comprising a distinctly separate strip 20, having its marginal edges turned under is shown at 2| and it has stitching 22 on each edge to enclose sepamtenmningstrings 25. The nylon strip 20 is then applied over the lower layer of canvas, duck, drilling, or textile material 5 and is fitted and assembled by tightening the running strings Ill and-tying same into a suitable knot on each side. InFig. 8,30 designates a coating of latex, or the like, sprayed on the under side of said layer 5, which coating '30 is in direct contact with the brush 3, and often proves effective in preventing undue wear on the layer 5 as well as increasing the frictional relation between said layer 5 and brush 3. And we therefore wish'to claim'this feature in the appended claim. 7

Thus, the two layers are separately assembled but are in cooperating association so 'as'toinsure the outer or wear-resisting permeable nylon layer for carrying the wax or finishing material, and for direct contact with the avork by the underneath layer of cotton or equivalent textile material, protecting the bristles-3 from being clogged or damaged with wax and also insuring suflicient friction so that in the rotation of. the finishing roll the layers will be carried around the same despite the pressure applied between the work and the outer layer.

In the form wherein each layer is separately assembled on the roll, we may turn under the marginal ends of .the nylon roll'and unite same by stitching26 or may simply lay the same over, as illustrated inFig. 6. Preferably, however, we turn in the edges, as shown in Fig. 3.

It will thus be seen that our inventive combination of an outer permeable, Wear-resisting layer, and an inner backing layer, which not only protects the bristles but insures frictional .engagement between the roll and the cover, as well as affording a padding andcushioning element for the outer layer, is provided, the outer nylon layer being preferable for directpolishing contact'with the Work because of its inherentcharacteristics for wear-resistance. Both layers are thus advantageously combined in a complete finishing roll cover, affording greatly increased wear, serviceabil-ity, and uniform action.

We claim:

'A finishing roll cover ofethe kind. described; comprising an underneath layer of cotton havin the under surface thereof coated withlatex, said layer constituting .a friction-contacting element on a finishing brush, roll, or the like. vandan outer layer of nylon, and means uniting said two layers adjacent their marginal portions.
