Be it known that I, ALLEN G. ,WILLIAMs a citizen of the United States, residing at Baltimore, in the State of Maryland, have invent` ed certain new and' useful Improvements in' Bnrnishing-Rolls, of which the'followin g is a specification.

' This invention relates to a novel construction of burnisliing-rolls for use on certain' ro parts of boots and shoes, such as the Shanksv vand heel edges, which have been coated with blacking composition.

The object of the invention is to provide a wheeler rotary body ot suitable material, such jig. as metal, and to loosely attach to the perime Iter 'of said wheel radiating leather' paddles,

whereby the bu rnishin g action on the article l -to be burnished will consist, essentially, oi'- vslight blows or taps rapidly applied. By the -construction herein described there is lan absence of a spring or yielding pressure of the burnisher on the surface that is treated and an absence of a yielding rubbing friction on'v said surface. v

The invention is illustrated in the accomL panying drawings, in wliieh- A Figure l is a diametrieal section of the burnishing-roll. Fig. 2 is a side view ofthe burv nishing-roll, the outer broken circle indicating the ends of the leather paddles, and a portion' of the wheel-rim being broken away to show the inner looselyattached ends of .the paddles. Fig. 3 is an edge view of the burnishing-roll, showing that by reason of the loose attachment of the leather paddles they may assume a diagonal position crosswise of the wheel-rim. Fig. l shows one of the leather paddles-detached.

The wheel or rotary bodyA may be made, and preferably is made, of a single piece of metal. It has a central bore b to receive a revoluble shaft, on which itis to be secured by any suitable means. In the present instance a setscrew c is shown for this purpose. The rim of this wheel has a groove f7 around it, and an inward-turned flange e is on each side of the groove. The two flanges e confront each other,

the` groove itself.

rlhe paddles F may be made of any suitable smaller than the groove d crosswise. .thus be 'seen that the paddles may be loosely attachcdto the perimeter of the wheel by sim.-

lnaterial g but I preferleather of uniform thickness. Each paddle` has two square notches g near its inner end, one on each edge, andthe two being directly opposite each other. The 55 square or rectangular notclrforms on the eK- posed-part of the paddle,arightTangled shoulder g' on each edge. These notches are larger than the inward-turned flanges c on the wheel, and the inner end .71,l of thepaddle is slightly 6c It will ply inserting the inner end 71y of each paddle into thegrooveffZ-and allow Ithe two notches 65 c of each paddle, to? loosely engage the two ilanges e,v as shown in'l Fig. 1,. Thus each paddle is perfectly loose in distinction to heingl clamped, and each isfree to have slight movement in .the channel independent of all 7i other paddles, allowing the paddles to assume a slightly twisted Aor diagonal'position. As the paddles are of. unitormlthickness' from endto end, the inner ends ,Zt in the groove will f be closer together than theoute'r ends, as seen 74 in-Fig. 2. Thus the burnishing,end'sbr outer ends of the paddles arespaceda pai:t;"permit ting each to 1n ake a tap or blowonthe surface to be bu rnishcd. By Ithus havingtle outer ends of the paddles'spaccd apart there is an 8 absence on the burnishing-riin of anything like a continuous rubbing-surface, and by the loose attachment of each paddle and its indc pendence of movement there will be no friction, rubbing, or spring-pressure on the ar- 8 ticle that is being'burnished, but instead the edect or action produced will be that of slight taps or blows very rapidly applied. Vhen the paddles have had their ends inserted into the groove or channel Where they are loose, 9 the right-angled shoulders g of the paddles bear on the peripheral rim of the wheel and serve to keep the loose paddles projected radially.

vVhere the paddles are made of leather, the g inner ends 71 can be'inserted in the groove cl by bending; but special provision is made for inserting the paddles to the groove. At one side of the wheel-rim the iiange e has a radial slot opening into the groove and wide enough i to admit one paddle edgewise at a time. The paddles are to he placed into the groove d by inishedwill not develop any injurious i .2sA

simply enteringthem one at a time through the slot and when each paddle has been er1- tered sliding italong the groove `to allow another to be inserted. After all the paddles have been entered the. slot iss-closed or illed by a block-fi, which .exactly iits int'o the slot.' This block has a flange j resting on the side o f the wheel, and a -screw k retains it in p'o-` lsition. The outer ends of these paddles, by

'reason of their looseness in the channel, may

.be made to assume a diagonal .position crosswse of the wheel-rimas seen in Fig. 2.

The paddles in :ny-wheel being loose may be easily detached and removed when worn.

By wear theybecome too short for use. When .thus worn, new paddleslmay readily be inserted loosely in the solid metal wheel.'

The velocity of the vrevolving wheel will 4maintain all the 'loosely-attached paddles in radial lines, Vand the tap or blow which each one makes on the article that is' being bureffects, suoli as burning the article.

1 The paddles are to be cut by means of a die from scraps of sole-1eather or split leather. In this way many scraps or smal-l pieces can be utilized.

It is obvious that the iuventionlis not limited to making the metall body or wheel in theform of a solid single piece, as shown in4 the drawings. e

Having thus described myinvention, what "I claiin as new, and de sire to'secure by Letters 1. In a burnishiug-rll the eolnbinationof a wheel having a circumferential channel each side :of which is provided on its peripheral rim with an inturned flange; paddles which are separate and independent of each other 4and each having square notches which form right-angled shoulders and take loosely over the said intu-rncd flangestlie saidright-angled shohlders bearing lonthe peripheral rim,... n

kept projected radially and one or more paddles may `be removed or inserted without changing the wheel-or disturbing 'theother -paddles.-

'n n A n n n I ,i A burnishing-roll having in combination a wheel-provided on its rim with a circumfervof the wheel, whereby the loose paddles 'ai'e eutial groove;` paddles iittingloosely in saiii groove and radiating from the wheel and free to -move in the' groove independently; and

means to retain the movable paddles in said groove in their radial position.

3. Aburnishing-roll having in combination a wheel or circular body provided Von its rim with a`oircumt`ereutial groove having inwardturned flanges; andpaddlesof'uniformithicksingle piece having a circumferential chan- -nel provided with inturned flanges; and ra-/y diatng paddles movable in said channel.

5. Aburnishing-roll having in conibinatioil A a wheel or circularbody provided with a c eumferential groove having inward-turid v llanges'and a slot through one iiange open', ig.

into said groove; means to close'. said s t; and paddles secured in said groove loos ly by the said inward-turned anges.

In testimonyl whereof I aflix my signature in the presence of two witnesses.
