Jan. 27, 1925.-
Patented Jan. 27, 1925.
Application filed April 18, 1921. Serial No. 462,431.
To all whom it may concern.
Be it known that I, Lanarrs I-InNnTn NinLsnN, a subject of the King of Denmark, and a resident of Kolding, Denmark, have invented a new and usei'ul I1n1'n'ove1nent in Cylindrical or Ring-Shaped Brushes, of which the following is a specification, the principle of the invention being herein en plained, and the best mode in which I have contemplated applying that principle so as to distinguishit from other inventions.
The present improvements relate to that type ot industrial brushes generally known as rotary brushes, which are made up of several layers or sections, `firmly held together and mounted on a shaft through the Vmedium ot a suitable base or hub. One object ot the invention is theprovision et a brush of this type, in which the sections may be readily and inexpensively constructed out of any of the usual materials. Another object is to provide a convenient and satisfactory manner tor combining an assent blage of such sections into a unitary structure, in` which the brush material is not only firmly `held but properly distributed and supported so as to give maximum service. Still another object is the provision of a unique form ot base or mounting for a brush of the general type in question, and particularly one ot the special construction hereinbefore referred to. l
To the accomplishment oit the foregoing and related ends, said invention, then, consists ot' the means hereinafter ilully .described and particularly pointed out in the claims, the annexed drawing and the following description setting forth 1n detail certain mechanism embodying the invention, such disclosed means constituting, however, but several of various mechanical forms in which the principle of the invention may be used. Y
Figs. l to 3, inclusive, illustrate in crosssection the appearance oi? an individual brush section in successive stages of manufacture; Fig. Il is a brolien side elevation of such section in the stage of manufacture illustrated in Fig. 3; Fig. 5 is a cross-seetion of a. completely assembled brush showing more particularly the manner in which the brush sections are mounted on they holder therefor provided; F ig. G is a similar section showing a modification in the construction of such holder; Fig. 7 is a view similar to Fig. t, showing a modilication in the construction olf the individual sections; and Fig. 8 is another view similar to Fig. 5, but showing a diiiere/nt form of base, as wel] as a modiiicat-ion in the manner in which the assembled sections are secured together.
A characteristic feature in the construction of the component layers, sections or brush rings of my improvedl rotary brush is the inclusion of suitable rings of pasteboard or equivalent fibrous material as spacing pieces between the bent librous .material which constitutes the operative part ot the brush, similar rings being also used as spacing members between adjacent sections. Another characteristic .'leature is the use ot one or more rows et nails that are driven transversely into the assembled sections composing the brush, such nails being driven in from both sides so as to penetrate the successive rings of pasteboardor like meterial, and being spaced so closely as to prevent the iibrous material from being torn loose or drawn out from the brush when the latter is in use.
In the illustrative section or layer, as illustrated in Figs. l to t, inclusive, it will be noted that the hbrous material 2 is bent `around a ring formed wire l into open U- ring 3 of approximately the same thickness as said wire l, euch brush material bemg thereupon pressed against such ring and held solidly in place by means of one or more rows oi stitching et..
rIhe manner in which the brush material is assembled on the wire ring l, and then pressed against the pasteboard ring and stitched to the latter 'forms no part ot the present invention, but it may be eiqilained thatspecial devices may be utilized to advantage in this coimeetion whereby the sec* tion may be thus preliminar-ily formed and then placed under a sewing machine in or der to stitch the brush material and the pasteboard ring together. t will be observed that the stitching i is applied directly to the brush material without using any other means for holding the saine in l (it) place orafte-rwards bending same into rotary shape; also that in place of such stitching Lone orn'olie rows of'steellwiie staples, or specially bentsteel pieces l2, may be employed as shown in Fig. 7, such staples preferably over-lapping eachother soas to.. give th esa-me eiiect as a continuous stitching.v
Due to the fact that the ring-shaped pasteboard or fibrous inlay 3 is of'fapproxim'ately the same thickness as the winding wire or ring l, such inlay serves to equalize'the pressure when a plurality of sectionsareput. to gether, and prevents suelr lpres'sii're `from being -loea'lizedzugainst thefsucees'sive wire rings. lith sections ofi the construction described itA is possibletol assembleA afrotary brush `Aof any desired thieltness, and the methott'of constructiqn' is equally adaptable to sectionsv ofv different diamters.
In assemblingV a pluralityV of sections to form arotary -b'r'nshof desired 'thi` ckness, I place betweensuch ysections pasteboard rings 5 as shownin Fig. 5, these vrings'being'of slightly :larger diameter internally` than'the brush sections.z Said ringsarefirst'dipped in glue before being laid betweensuelrsec tions, which: are thenI pressed together, 4and when dried constitute, in edect, a unitary structure. In `order' tovfill out the spaces that are leftl'between the interiogrfparts of said r:rings andthe brush sections, f when thus assembled,` alayer 6 .of molten pitch ymay 'be applied in'thecentral openingso as to form a smooth cylindrical Vw all and I'further assist in binding the lsections together. I niay also 'drive' one or more circular rows 'of broad-head nails 13 j through theassembled body of brush sections, as shown in Fig. 8, such nails being thus driven'y from opposite sides adjacent' to the :wire ringsl; solas `to penetrate more Vor less. completely the Vsuccessive vpastebo-ard rings 3 and 5. These nailsiserve' to strengthenthefbaseof the brush and'more firmly securethe brush material to such base," as will bey readily appar? ent.
Forv the, pur ose of mounting the finished brush on the s raft or arbor I -halve' -designed the special mounting or holder shown "in Fig. 5, such mounting,comprisinga transversely split band 7,'andtWo co-,operating side plates or rings S. The inner faces of thelatte'r are cut aWayor otherwise 'formed to presentco'nical bearings that contact with the 'respective sides ofthe band 7 sothat When side plates are ydrawn together said band will be expanded f. against, the' vcylin drical Wall lof the central openingfinv'the brush, thereby binding such bandand-brush together and forming "a vcomp act unit. VAAt the same time the bru'sh ispreventedfroin turning ,on the 'mounting' when in use'.
A brush constructediin the fashion hereinbefore'described may of course be mounted on'other kinds of hubs thanv the special one just described. Thus, as shown in Fig. 6, the hub may consist of two complementary wooden rings 10 with laterally projecting flanges, between which the brush is held,
said rings being drawn together by nails or merely of side plates similar to the metal Side plates 8 shown in FigJ. e As in the case of hubs'ections of Fig. 6, so the rings ll in F ig.V 8 `will beheld together with nails or equivalent securing means.`
Other modes of applying the principle of,V
myv invention may e em )loyed instead of the' one explained, change lbeing made as regards the mechanism herein disclosed, provided the means stated by any of the followingclaims or thefequivalent of such sta-ted means beemployed.
I therefore particularly point out and distinctly claim as my invention :M
l. A rotary brush section comprising a baseer-ing, brush material looped uponsaid l' ring, afiatkring inserted between such loo )ed material adjacent said ring, and fastenin" means forl securing such material tosaid 'flat ring.
'2. A rotary brush section comprising a -base`ring, brush material loopefdlupon said ring, a fiat ring inserted between such looped n'iaterial adjacent said ring, and stitching passing through such material and Hat ring.
3. In` af rotary brush, Vthe combination of a plurality .of sections, each comprising a basel element, brush material looped upon said element, a fastening means securing suchmaterial to said element; and fiat spacing rings interposed between successive sections, said'rings and sections being secured together. i i 4 4 In :a rotary brush, the combination of al` plurality of'sections, each comprising a base element, brush material looped upon said element, and fastening means -securing such materi'alto said element; and liat spacing rings interposed between successive sections, said rings and sections being ,glued together.v
5. In a rotary brush, the combination of a plurality ofvsections, each comprising a base element, brush material looped upon said element, [and fastening ,means securing such material kto said element; andiiat spacing rings `of larger internal diameter than said sections interposed between successive sections, `said rings and sections being glued together, and the spaces left in the central lili) rings interposed between successive sections, said rings and sections being glued together; 10 and a olrole of nails transversely driven into such assembled sectlons and rings.
