12 Claims. (01. 51-263) t This invention relatesto an applicator for applying lubricants, polishing compounds and soft plastic materials of low viscosity to grinding and polishing wheels, belts and like high speed finishing surfaces. For the purpose of illustration my invention will be described particularly in relation to the application of tallow to finishing wheels, wherein the problems to be solved by the invention and the solutions thereof will be readily apparent, the use thereof in connection with other polishing compounds and lubricants on moving finishing surfaces being readily apparent from the specific example described.

In the line grinding or polishing of articles it is necessary that a suitable film of lubricant be maintained on the surface of the wheel or polishing means. Tallow is one of the cheaper and more satisfactory materials for this purpose as it can be removed easily from the article by a weak alkali bath and water rinse. However, it has such a low melting point and low viscosity that it is very difficult to apply onto the moving wheel as it becomes soft and semi-fluid under the slight heat therefrom and collapses so that it cannot be held firmly against the wheel. In order to raise the melting point of the tallow, stearic acid, paraffine and the like have been mixed with the tallow, forming therewith a homogeneous massof sufficiently high meltng point and rigidity to be pressed and held against the wheel occasionally without collapsing thus causing enough tallow to be spread and retained on the wheel to produce the desired coating.

These methods, however, have serious objections. The loss of tallow is quite pronounced, a large proportion flying off from the wheel and mass during application due to both centrifugal force and. the semi-fluid state of the tallow. Further, the stearic acid is relatively expensive and neither it nor paraffine have-any lubricating effect. The stearic acid and paraffine adhere to the wheel and, of course, are transferred onto the artcle being polished or finished. To remove the paraffine from the article is much more difficult than removal of the compound or lubricant. In case the article is to be plated, it'must be perfectly clean and free from all such foreign substances, as their presence on the article very deleteriously affects the platingoperation.

One of the principal objects of thepresent invention is to provide an'applicatorby which oils, soft lubricants, polishing compounds and plastic materials having low melting ponts and viscosity may be applied efiiciently and easily to the moving finishing surface without material loss of the lubricant or compound so applied.

Another object is .to effect a more even distribution of the applied material over the finishing surface and to reduce 'splattering and loss of the material.

Still another object is to provide an applicator in which the materal is stored and ready for use at all time and which is in a form which may readily be grasped in the hand of the operator and forced against the moving surface of the wheel.

' More specific objects are to provide an applicator of this character which is reinforced against radial and axial collapse even when used in'con- 7 fnection with'a very soft plasticv or fluid material to be applied, which will be worn away readily by the action of the wheel as the material contained therein is applied, and which is composed of a material which may readily be removed from 5 the article on which the wheel has operated by the same bath and method that will remove the lubricant or material applied.

Other objects and advantages will become apparent from the" following specification in which reference is. made to the drawing, wherein Fig. l is a side elevation illustrating a form of applicator embodying the principles of the present invention and the manner in which used;

. Fig. 2 is an enlarged side elevation of the aplplicator, part thereof being shown in section for clear'n'ess in illustration; Fig. 3 is a cross sectional view of the applicator taken on a plane indicated by the line 3-3 9 in'Fig. 2; and r Fig. 4; is a cross sectional view of a'modified form of applicator.

The applicator comprises generally a tubular casing 1, which is preferably of sufficient rigidity to be, self-supporting and within which is a reinforcing and'retaining core designated generally at 2. The core 2 is cellular in construction, the cells thereof being filled with and retaining the lubricant or material 3 to be applied to the moving surface of the wheel or other moving polishing surface.

In the form illustrated, the core is composed of a spirally wound corrugated paper of the type having a corrugated sheet i, to one face of which, 1 along the crests of the corrugations, is secured a backing'sheet 5 to retain the corrugations in shape. The resultant sheet is preferably wound spirally, with the backing, sheet 5 outwardly so that the wall portions'of adjacent turns of the 1 material either solid heating appreQiablyadjacent i worn away soft, plastic material to be applied, preferably by pouring it in liquid state, into the ends thereof so that it may flow down tional material is added until the applicator is entirely filled. s V I The reinforcing and retaining core 2 is preferably self-supporting, as shown, and held by friction, gluing or otherwise within the casing 1. Thus the casing is reinforced both radially and axially. Both the casing and the core are preferably of a fibrous or absorbent material which may be permeated readily by the oil, lubricant, or material to be applied thereby, so thatsuch materialis firmly held by the core a'nd'assists in swelling the core and firmly interlocking it with the casing.

If desired, instead of the casing 1, the outer layer of the sheet 5 may form the casing, but this is usually not as satisfactory as it does not have as great rigidity.

The applicator with the material therein is forced endwise against the finishing surface [on which the material is to be applied, as illustrated in Fig. 1. The applicator itself is of material of a characteristic which will be removed or gradually and readily by the action ofthe Wheel. Consequently, the end of the applicator quickly assumes snug engagement with the wheel for the entire diameter of the "appli- 'cator.

The heat from the wheeltends to melt or reduce the viscosity of the material contained in the applicator but it cannot afiect any great portion thereof so that the portion will move as a mass, due to the'retaining and heat insulating eifect of the cells or pipes. Further, heating of the material in that portion of the applicator actually engaging the wheel does not result in material in the ap walls. Again, the holdthe material so that a uniform 'plicator because of the cell cell walls and the casing wall against the'face of the wheel light film thereof is'applied and spread thereonto. Furthermore, any appreciable mass of the material is prevented from flowin'g or tearing loose and being thrown off by the wheel, due to the fact that the core andcasing material retain it within the limits of the end of the applicator. Thus much more of the material is actually applied efiiciently with a resultant saving in the amount required.

In Fig.' 4, a slightly modified form of applicator is illustrated, in which the corrugated paper for 'the core, instead of being spirally wound, is cut or folded into parallel strips, placed .face to face, thus providing. a core having parallel laminations rather than spiral laminations.

It is apparent from the foregoing description that an applieator'of the character described may be utilized for applying, substantiallyany or liquid to the finishing surface of the wheel While the surface is in motionan'd that thesame is economical both as to manufacture ,and use. U
