Nash Company, Milwaukee, Wis., a cor poration of Wisconsin Application July 29, 1935, Serial No. 33,647 45 Claims. (01. 51-154) My invention relates to improvements in ?nish ing and polishing machines of that type in which pieces of work in rotation are carried by a re volving turret or drum successively into contact 5 with polishing, bu?lng, or other ?nishing devices occupying positions which are predetermined in correspondence with the requirements of the in dividual pieces of work to be ?nished during a given setting of the machine. Heretofore each polishing or ?nishing element 10 or member required independent setting and lock ing, and as such members are often very numer the various lines of ?nishing and polishing mem bers are supported, whereby the machine may be adapted for turrets of different diameters, and for work pieces of differing diameters. Further objects are to provide improved sup- 5 porting devices for sanding and buf?ng members; to provide means whereby holders for the yield ing back members associated with such sanding or buf?ng members may be lineally adjusted in any given series without requiring readjustment 10 of associated tensioning means; and to provide controls at one end of the machine, whereby the ous the setting up operation consumed consider able time and the desired degree of accuracy was 15 not always attained. 7 Primary objects of this invention are to pro vide means whereby one of the pieces of work may be utilized to simultaneously position all ?n ishing and polishing members of any given lineal series and such parts associated with said mem bers as require corresponding positioning adjust ment, and whereby all of such members may be simultaneously locked in their proper positions while they are being held in such positions by the work. It is my object to provide means for utilizing a piece of work to mechanically set up a machine of the described class by adjusting such piece of Work in a controlling position with reference to the members requiring adjustment for such a set ting up operation. It is also my object to provide means whereby the same piece of work may be successively ad vanced from one controlling position to another various members can be locked, released, or re adjusted for any given line instantly and simul taneously; and to provide means whereby each member in any series may be independently piv oted to a common support and adjusted either in common or individually. In the drawings: Figure 1 is an end elevation of the machine em bodying my invention, with a portion of one of the arcuate end walls or standards of the brush supporting frame partially broken away to dis close the mountings for the brushes employed for tensioning the strip of sanding paper or buf?ng material. ‘ - Figure 2 is a detail View of one of the standards, showing means for effecting bodily adjustments, either forwardly and backwardly, or laterally, and also showing means whereby one or more upper series of brush holders may be swung forwardly and backwardly independently of the lower series.

' A further object is to provide means whereby all of the adjustable members in any such lineal series may be simultaneously locked while per mitting independent readjustments of any mem ber in the series in correspondence with special 45 requirements for increased or diminished pressure of the ?nishing or polishing device upon work. A further object is to provide means for ob taining pressure variations common to all mem bers in any given line of working members or elements, whereby such variations may be ac complished simultaneously. vA further object is to provide means whereby lines of ?nishing and polishing elements and as sociated parts may be bodily adjusted to increase 55 or diminish the curvature of the are along which of one of the end standards or frame member Figure 4 is a fragmentary perspective view of one of the brush mountings, a portion of the brush being illustrated.

In the following description the terms “polish ing material” and “polishing strips” bu?ing material of any description. The term “brushes” will be "employed to designate any yielding backing material for holding the polish 7 ing material or members in contact with the work and in conformity to the contour of the work. 20 The term “work holding carrier” will be employed to designate any means for presenting the work to the polishing strips‘, the work being ordinarily rotated about. its own axis while it is being pre sented in order that all surfaces of the periphery may be polished. ' . ‘ The form of the carrier, the means for actuat ing it, and the means for rotating the work are I not material to the subject matter of the inven tion herein disclosed, and it may be assumed that 30 these portions of the machine will conform gen erally to machines of the type disclosed in expired patent-to A. H. Matteson, dated November 9, 1915, and' numbered 1,159,696. Therefore, detailed illustration and description of the work carrier and work rotating means are deemed unnecessary. In Figure 1 the work carrier 20 is illustrated conventionally, and'pieces of work are indicated at A as they are'being conveyed by the carrier into contact with strips of polishing material 722 40; which depend from their supports as hereinafter described, and are held against the work bybun ' These standards being arcuate, an additional’ _ adjustment of their ends is desirable in order‘ to permit the upper end portions to swing down 10 wardly toward the work carrier, where a rotary carrier of'the turrettype is employed.

A set screw 38 extends through a slot 39 in the section 35 and clamps that section'to the lower section 25 in the rear of the pivot 37. The slot 39 is of su?icientlength to allow the section 35 to be swung from its full 20 line position in Figure 2 to the dotted line position when the'lower section 25 has been ad justed from its full line position to the dotted line position in that view. ‘ .

' The end standards are connected by rock shafts 45, each of which supports. one lineal series of brush holders. The brush holders 46 of each series are pivotally attached to a longi tudinally extending frame composed of bars 41, 48, and 49, which are connected at intervals by divider plates 50, preferably welded to the'bars 41, 4,8 and 49 to form a substantially rigid frame, dles of broomrcorn, whichtconstitute resiliently an enlarged fragment of which is illustrated in yielding backingsvor brushes 23.

' In place of the push rods 56 shown in Fig A tension spring I23 connects one arm of the bell crank with the arm 80a‘. The bell crank is 50 pivoted at I25 to a projection on the arm 86a. Link rod lZI extends through an arcuate slot 90a formed in the standard. It also extends through an aperture in the armY8Ila which serves as a guide for the link. f In all other respects the structure embodied in this modi?cation may be assumed to be sub stantially like that above described with reference to Figures 1 to 6, inclusive. In the modi?cation disclosed in Figures 11, 12,. 60 i3 and-1d the brush holders are associated for adjusting purposes in both lineal and arcuate ' series, whereby those of several linear series at dif ferent levels may be simultaneously adjusted from a single piece of work. In the modi?cationillus trated, it is not necessary that the piece of work, should be mounted on the rotary turret or car rier. It may be supported in a centered posi tion upon ‘the pivoted arms I76, and these arms may then be lifted to push‘ the work into actuat~ ing relation to a set of gauge ?ngers, each con nected to position one of the brush holders. ‘ This specially mounted piece of work'may thus be utilized to mechanically position all. associated brush holders simultaneously. Also; in the modi?cation now to be described, ure 1, levers I41, one for each brush holder, may " be pivotally'mounted upon a longitudinally ex tending pivot red I 48, this pivot rod extending . through an intermediate portion of the_lever.. . One arm of the lever has a rounded nose I49 which bears against the brush holder below the brush holder pivot rod 531), whereby to angularly position the brush. The brush holder hook 55b preferably has an extension 5 50 which bears upon the upper surface of the nose portion M9of'the lever, whereby upward movement of thisarm of the lever will positivelyswing the brush 23b downwardly. Movement of the lever in the op-' posite direction will of course tend to swing'the brush upwardly. The outer arms of the-levers I41 are connected in an arcuate series by links I55, whereby movement of anyone lever is trans mitted toeach of the others in this arcuate series, 65 thereby adjusting all of the associated brushes simultaneously in the same direction. This adjustment 'of the levers I41 in each ar- 2 cuate series may be simultaneously accomplished by mounting a set of controlling levers upon a pivot rod I60. The short arms IEEI of these con; trolling levers are slotted and receive the pivot pins I 62 which‘connect the links I55 with the outwardly projecting arm of one of the levers." I41, whereby movement of the arm I6I of the 75 5 2,119,954. controlling lever will be transmitted through the pivot pin I52 to the lever I41 upon which it is mounted, and through the links I55 to the other ure 14, wherein individual collars are mounted upon the shaft I30 and secured thereto-by set screws I15. These collars have eccentric ?anges levers M1 in the same arcuate series. The controlling levers are provided with up wardly extending arms I65 which carry con tour testing or gauge ?ngers I56 adapted to bear upon a piece of work A’ which has been cen tered between supporting arms I15 secured to an oscillatory shaft or rod I'll. As shown in Figure 12, these controlling levers with their con tour testing gauge ?ngers IBIS are arranged in a longitudinally extending series upon the pivot rod I69 and are adapted to adjust associated 15 brush holders in conformity with the contour of the particular portion of the work with which any given gauge ?nger I66 may contact. Levers i555 may be locked on the pivot rod Hit by means of clamping nut I61, thereby locking all the levers I41 in their adjusted position. Therefore, in setting up a machine of the type disclosed in Figures 11 and 12, a piece of work may be centered between the supporting arms I15 and swung upwardly into contact with the gauge ?ngers I56, thereby adjusting all the brush holders in conformity with the requirements of the work. Like adjustments will be made for each brush holder in any given arcuate series, whereas different adjustments will be made in each lineal series in correspondence with the diameter of the Work against which the re spective gauge ?ngers I55 may bear. In machines of the type illustrated in the draw ings, the polishing materials delivered from suc cessive rolls 69 or 6% will ordinarily be of dif ferent grades, the upper series of rolls 6% hav ing the strips surfaced with a comparatively I350 encircled by straps I360 connected with the arms I310. These arms I310 have studs 53c with which the brush holder hooks 550 may be engaged. Otherwise the construction of the machine may be the same as that shown in Figures 11 and 12, or if desired, it may be, the same as that disclosed in Figures 1 ‘to 6, inclusive, if 10 these eccentrically ?anged collars are mounted upon the rock shafts 45 disclosed in those views. The individual adjustments made possible by the use of separate collars I350, as shown in Figure 14, and separate pivot studs to which the brush 15 holders are hooked, as shown in'that view, may be utilized to adapt these machines for special duty, in which a variation in polishing pres sure at one or more stages in the polishing op eration becomes desirable. . ~ 20 In Figures 12 and 13 it will be observed that the links I55 are arranged in pairs for mutual reenforcement and to allow polishing strips 221) of substantial width to occupy the space between them. These links may be offset from each 25 other, as indicated at I11 (Fig. 13), to permit of their connection with the uniformly spaced brush holder adjusting levers I41. This also facilitates access from the rear side to the levers I41 and to the eccentric members I350 when the 30 latter are made individually adjustable. From the foregoing description it will be un derstood that in the form of construction dis closed in Figures 1 to 6 the means for holding the polishing strips to the work under the de 35 sired pressure in any given lineal series may be simultaneously adjusted by a specimen of the work mounted upon the carrier and conveyed coarse abrasive material for rough polishing or thereby into contact with the polishing strips sanding operations.

I 41. In this manner one series of brushes may be relatively advanced or retracted to vary the resistance which the brushes exert to the pressure of work conveyed by the carrier along the associated pol ishing strips. . With some classes of work it may be desirable to provide for individual adjustments of the brush holders independently of the setting of the levers I41 and independently of the oscillatory adjustment of the shaft ISII. This may be ac 75 complished by the construction shown in Fig positions.
