.To all whomitmay concern:

invented jcertain new and useful Improvements 1n Burnlshmg-Machmes, of which the following isa specification.

The object'of my invention is to produce a 01193.1),15511111313, and highlyv efiicient 'machineforlournishing or finishing leather articles or the like, or any other kind of mav terial or art-iclefto be burnished or finished.

The salient features of the invention consist in providing a; heated slotted finger or:

burnishing tool Whichreciprocates or. oscillates in connection wlth pressure and oscillating feeding mechanism for automatically feeding the material toJbe burnished and thus imparting to the material a reciprocating or oscillating fmovement while being burnished. I p

.The'various features and-advantages of the invention will readily become apparent from the following specification.

My machine consists of-Ia frame 1 providedwith an upward and'forwardextending portion or arm 2; in the forward end of arm 2 I placevertical'bearings.3 and4,'see Fig. 6. The purpose of the bearingsv S and fl, is to hold the shaft 5 in a vertical position and'to allow same to slide freely. Fasto Shaft at r;end,ipna a.

At theilower Patented A1 a said sorewactingas a stud oriaxis'for feed roller 8 which is also attached to saidarm 'through medium of said screw; [The feed. roller ,8 has a knurled or'roughened surface as shown 111 Fig; 12. On the shaft?) and 7 between bearings 3 andf4, Ifastenc0l1an9.

vAroundshaft 5 and placedgbetween the bear- 1ng-3 and-collar 9, Icompres's the spring 10 as shown inFig. 5. The action of. spring 10 against therigidbearing 3 and the collar '9 'onshaft, 5, is, to expand laterally, thus cause ing a downward pressure :tothe shaft 5 and arm fi and consequently feed roller 8. l

I In the upward and forwardextending,

arn1.,2,'and' atv its middle, I construct bear'i ng 12. Through bearing 12 I oscillate shaft 13 and at the upper end of shaft 13, I fasten collar" 14:. jAt the lower end Ofshaft 13, I securely fasten the housing 15, Between the housing :15 andlower'end. of bearing12, I

place an asbestos washer 16.- -I hus"itcan be seen that the collar 14: acting'as athrust bearing against the upper face I of bean.

ing 12, will hold the housing 15 :in position. The housing 15 is constructedso as to admit an electric unit .17 Atthe' forward end of housing 15, I securely fasten the burnishing 'toolo'r finger 18, projecting downward and.

away from the housing 15 ata suitable angle; see Fig. v6. Thus it willbe seenith'at when the electric current is applied; to' unit the lower end of tool '18, I place a slot'19.

,fIn jorder to oscillate toollS, I adoptj the 7' following means. In the upward and forward extending arm 2, I. place bea'r'ings120 and 21; see'Fig. 10. Through these bearing's the shaft 23.--is revolvedandllheld inposition by means of the collars-24-fand 25, which are-fastened to shaft 23. The forwardend of shaft '23, isturn'e'd smaller in diameter and offset, thus forming an eccentric 26. 'Journaled on this eccehtric26, I

1 connect thelink27, as shown in Fig 10.

The other end of link 27 is journale'dlon the. stud 28, which is secured to housing 15,

. at bearing 29. Thus it can readily, be seen that when the shaft 23 with its eccentric end is revolved, the housing will receive an oscillating motion, through themeans of.

the link 27 and its connections and also the finger 18, which being connected'to said.

housing, will reciprocate with it.

automatic feed ofmy machine is one of its important features for burnishing. My object is to feedthe lateral edges of the material to be burnished, through the "slot",-19,1 in the burnishingtool 18, and also to reversefthis feed, intermittently. To ob- .tain thisres ult'I adopt the following means.

.in which I oscillate the shaft 32.

In the frame-1, 'I place bearings 30{ and 31, I V V I also place-the bearings 33 and 34 in the frame way or cam groove 44 to admit the roller 45 ,as shown in Fig.8 The roller 45 is gconnectedto-the sliding arm 46'by meansof a stud and must revolve fr eely on said stud. The sliding "arm 46, has a forked shaped end 47, which slides over and under the ;shaft 38. The colla-r'63 on shaft 3'8'holds thesliclingarm -46 in position against cam 41'. f-At'the otheren'd of the-arm 46, I connectthe rocking arm 48, at the point 49.

' "The arm 48 is "fastenedto shaft 32. At-the forward end of shaft 32, I also fasten arm 50. At the upper end of arm '50, at the point 51, 1 connect the feeding arm 52. The -=.'fee'ding arm 52', hasa fork shaped end 53, which slides over and under the roller 54.

"The roller 54, is fastened by means of a stud to; the arm55. Arm 55 is fastened to s-haft- 35 at, the forward end of said shaft.

The feedingarm' 52, is constructed'with a ffeedingplate 56; said plate being held in pOSltlOIi by means of screws 57 and 58. The

topof the frame 1,-is cutaway at the point 59, to allow-the feeding plate 56, to extend *up through the frame land to come into contact with the face of the feed roller 8;

*see Fig. 12. The top face of the feed plate 56, has a knurled or roughened surface, as

shown in Figs. 10 and '11.

*The feed roller 8, actuated bythe spring 10, has a downward pressureupon the feed plate 56 and the downward travel of the "feed wheel 8, can be governed by the collar 9 on shaft 5, said collar being adjustable, to and away from bearing 4, by means of a setscrew in collar 9, the said collar 9 then acting as a stop against the lower bearing 4, thuslimiting thetravelof feed wheel 8.

On shaft 35, I'fasten arm 60 and on main shaft 38, I place the cam 61, as shown in Fig. 7. I The cam 61 is constructed with one lscribed, must be timed as follows. 41, with its double acting'noses 42 and 43, will give a double oscillating action to shaft '32, during one revolution of main driving shaft 38, therefore shaft 32, with its double oscillating action. will give a double oscilnose 62; see Fig. 9. Connected to arm 60, at-point 64, I have-the sliding arm 65, with a fork shaped end, passing over and under shaft 38- The roller 66 revolving against the face of the cam 61 and held in position holding the roller 66 against the working surfaccof 02111161. A collar 70, holds the arm in'posltion against the cam 61, as

shown in Fig. 7'. Power is applied to shaft 23' through pulley 75. On shaft 23, I place spur gear 76 and on shaft 38', I place spur gear 77; the diameterof the gear 76 is one half the diameter of the gear 77 so that the shaft 23 makes two complete revolutions "while the. shaft 38 is making one complete revolution.

i In order to get aperfect burnishing effect, the slot 19 in the burnishing tool 18 lies approximately in the plane in which the work engaging face of the feed plate 56 engages the work. The feeding nechanisnujust do The cam lating action to the feeding plate 56. The cam 61, withits single acting nose, will give a single oscillating action to shaft 35. Therefore shaft 35, with its single oscillating 'action, will, through mechanism described,

drop the feed plate 56, below the surface of frame 1, thus causing an intermittent feed between the feed roller 8 and the feedplate 56.

The result obtained by this double action 0f the feed plate and the singleaction of dropping the plate is as follows. The feed plate, with its forward and backward and forward action, and in contact with "feed roller 8, will feed the material forward and backward and forward again, the single acting cam then coming into operation and dropping the feed plate below the contact bearing between the material and the feed roll and the feed plate, will release the material. The feed plate-56,.while in this position will then come back without feeding the material and again be brought into contact with roller 8 by means of the single acting cam. The double acting cam. then coming into operation repeats the function above set forth.

The material to be burnished or finished is placed upon the feed plate 56 and adjacent thereto and between said feed plate and the feed roller 8, the edge to'be burnished or finished extending into the slot 19 in the burnising tool 18 and while the burnishing tool is oscillating forward and backward the feed plate and roller are holding the material in alinement and the feed plate is also oscil lating forward and backward carrying the material with it; thus while the burnishing tool is working backward and forward the material is also being workedriorward and backward and thus a double action is exerted upon the edge of the material being burnished; this action preventing any deteriorating or ill efi'ect upon the material; this action being continuous and only. inter rupted when the feed plate 56 drops to begin refeeding. By using my inventiondelicate' and easily marred surfaces can be acted upon and properly burnished without de' stroying or injuring them in any way. By

While I have described and shown eerf tain specific mechanism for carrying out my invention, it will be readily seen that the same is capable of considerable 1nodification and change without departing from the spirlt and prlnclple of my invention, and I wish to be understood as claiming thatsuch modification and changes will still fall within the scope of my invention.

IVhat I claim as new and my invention and deslre to secure by Letters Patent 1s:
