This invention relates to means for bufing and burnishing metal articles in preparation for the application of protective coatings thereto such as platings.
The bufiing, burnishing and polishing of metals in preparation for the application of protective coatings, as for instance electro-plating, has always, so far as We are aware, been a slow, laborious, hazardous and expensive process. The use of fabrics, skins, leather and applied abrasives, in a rotary polishing wheel, is very costly and each article requires special buffs.
,Useful life of the buff is impaired by wear which increases with the complicated nature of the contour or surface acted on. This is especially tru where sharp edges are encountered and the abrading material of the wheel is rapidly torn into shreds by working against such edges or other rough surfaces. In such cases, an exhaust system is required 'to remove and dispose of the residue from the wheel with a considerable exe penditure of both power and labor.
Furthermore, the abrasives applied to the abrading wheel are rapidly dissipated and lost by centrifugal action,v thus creating a messy residue the removal of which applies an additional load on the exhaust. In addition, considerable effort and expense are entailed in the removal from the crevices of the treated articles of the abradant remaining thereon after the abrading operation.
The primary object of this invention is to obviate the objections above-noted by the provision of simple and efiicient means for buifing and burnishing meta-l articles while submergedv in or wet with a burnishing solution and at a considerable saving in time, labor and material used over the means heretofore used for the purpose.
, Another object of the invention is toimprove the abrading means heretofore employed byreducing to a minimum the dissipation of abrasive material. v
Another object of the invention is the provis'ion, in a machine of the class described, of an improved form and construction of rotary abrading element whereby abrading of an article may be accomplished in arapid, efficient and economical manner.
Further objects and advantages of the invention'will be apparent from the following detailed description and from the accompanying drawings illustrating oneembodiment thereof, in which f Fig. l is aplan .view ofan apparatus embodying the invention with a part broken away;
12 Claims. (Cl. 51-134) Fig. 2 is a rear end view of the apparatus with parts broken away; Fig. 3 is a side elevation of the apparatus with parts broken away; Fig. 4 is a top plan view of the rotary buffing mat of the machine, and Fig. 5 a section thereof on the line 5--5 in Fig. 4. I
Referring to the drawings, I designates the base frame of the machine, the top 2 of which is inclined to the horizontal and provided with an upstanding journal stud 3 with its axis normal to the plane of inclination of said top. A turntable 5 is mounted for rotation about the axis of the stud 3 and has a depending hub sleeve 6 journaled on the stud. The table 5 is formed by annularly fianging the sleeve at its upper end, and the outer edge of such flange is provided with a skirt flange 1 that is braced with respect to the sleeve by radial webs 8. The flange I terminates at its lower edge in an annular outtumed flange 9 to which the inner edge of an annular workcarrying rim portion I0 is attached. This'rim presents a broad article-supporting surface disposed in a plane normal to the hub axis, and it is perforated orof foraminous form to permit liquids to pass freely therethrough. In practice, it is preferable to make the rim I0 in sections; as shown, to facilitate building and to permit damaged parts to be easily and quickly removed' for repair or replacement. A series ofwork-carrying fixtures I lfmay'be fixedly mounted on the rim Ill formovement therewith, or the work-pieces l2 tobe burnished may be securedin some other suitable manne directly to the rim.
The hub sleeve 6 is provided at its lowerend with a large ring gear l3 that is driven at slow speed from a motor I 4 through suitabl reduction gearing. In they present instance, the motor pulley l5 has driving connection with a pulley I6 through a belt [1 and this last pulley has driving connection through suitable speed reduction gearing in the case l8 with a small pinion [9 in mesh with the ring gear l3. A substantially U-form of tank 20 forholding a burnishing liquid 2| extends around the front orlower side of the table 5, and. fora distance rearwardly at each side thereof, 'in the inclined plane of rotation of the work supporting rim ll] of the table. The bottom of this tank extends slightly below the table rim: l0, so that the rim and work, as they pass through the lower forward loop :portion of the tank, are submerged in the burnishing liquid 21 therein. The rear or terminal ends of the leg portions of the tank 20 are open to permit the movement pending flange or inner side wall part that-= terminates in adjacent relation to ansann-ularv splash flange 22 mounted on and projecting outwardly from a ledge on theetablelskirtrlinto.

The table 5 turns in clockwise direction and its rim l0, after leaving the outlet end of the tank 20, passes through a washingezone- Azand: 7
