The invention relates vto improvements in beveling. The object is to provide improved methods and 'means' forv b eveling flexible strips, especially the corners of the side edges of leather belts, by abrasion.

The invention comprises method and means whereby the strip is supported and moved so that the corners of its side margins will cross the paths of travel'of a plurality of abrading devices.

The invention 'comprises a plurality of pairs of cog-operatingr rollers, some or all being power driven, and associated supporting and guiding mechanism, for causing thestrip or belt to travel in a" desired path, and ra plurality of grinding or abradingelements projecting partway into the path of travel ofthe belt, that is, projecting suiiiciently into said path to abrade the upper and lower corners of the side edges of the belt. These abrading elements are also power driven.

The invention also comprises means lments, with respect to the path of travel of the body operated upon. The invention also includes improvements in details of construction and operation.

Referring to the: drawings, which illustrate merely by way of example, suitable means for effecting the invention. Y

In Figs. 1 and-3 are shown four pairsof cooperating rollers, these rollers are num- 45 bered A6, 7, 8, 9, 10, 11, 12 and 13, respectively.

The device herein illustrated Y and described, by Yway of example, is suitable for operating upon strips of leather used in the Vmanufacture of belts for wearing apparel.

50 l The strips are adapted to pass between the inclusive. j Rollers 6 to 9 inclusive are driven for supporting and adjusting these abrading eley r35 of the abrading wheels. #The adjustment rollers of each'pair, and between the guide elements 14 and 15,v positioned'between the pairs of rollers and above and below the path of travel of the strips. The construction of the guide is shown in Fig. 5.

The several rollers are drivenby gears 16, 17, 18, 19,20, 21 and 22. Gear 16`is driven bysprocket 23, which is 'driven through the chain 24, from sprocket 25 on counter-shaft 26. Counter-.shaft 26 is driven from, a sprocket'on the reducingfgear 27, which 'is driven by`motor28, as shown inFig. 1. j This description refers to rollers 10to.,1`3

by a similar setof gears 19 ,to 22inclusive, sprocket 23'-, chain V24 and sprocket 25 also oncountershaft 26. f V Y Fig. 1, shows the second, or Bunit Aof rollers and the driving meanssimilar t'otheflirst 17.0 unit' of rollers,fexcept: that the secondfunitis oifset from the first, as'shownj in Fig. 2, and laterally adjustableas hereinafter described. Flanking,they several .pairs .of rolls are the grinding. orabrading wheels, l30, `31, 32 and 75 33.V Eachabrading wheel is mounted in a suitable :frame such as 34,shown in Figsfl and f2. These frames are adjustably mount ed, by means of the screws andfslots 34', on the machine' and. provide bearings-forl the shafts of the frames 34 is secured byj'theV adjusting A screws 36, for adjusting the abrading wheels with respect to the belt to .be operated upon.

The grinding wheels and 31, on lone side of the machine are mounted on shafts provided with pulleysr39,1 and 40 driven by belts V41 and 421fromthe counter-shaft 43 which is Adriven by belt 44 directly from the `motor28. `Counter-shaft 43 also drives through belt 44', `the Vcounter-shaft 45, which in turn drives wheels 32 and 33, which are on the other side of the machine, in a similar way.

One roller of eachpair of rollers is arbitrarily movable and spring controlled,` and one roller of each has aiixed bearing.' Referring to Figs. 1 and 3, roller 11 is mounted on'a bifurcated arm 47, connected to hand lever 48, mounted on shaft 49, which lever 48 is'lcontrolled by spring 50,v normally to 100 :the movement -.0;f a 'roller towards :its co-.op`

erating roller. v

By the simultaneous operation of levers 48 and 54 the rollers of one unit may be separated for the purpose to be described.

For the purpose of adjusting the machine fordifferent widths ,of belt, one unit is movable laterally toward or away from the line of the other unit. This is accomplished in the following way:

The unit, marked A, is fiXed, and t-he unit marked B, is movable. The frame 57, Carrying unit B is slidably mounted on a stationary `part of the machine by the screws ,and slots 58. The frame 57 is provided with the lug 59, co-operating with thesnitably mounted screw 60, operated 'by the hand wheel 61, whereby the frame 57 .of said unit B may be moved laterally toward or away from the longitudinal :line of the fixed unit. This adjustment may be arbitrarily made with a belt, of the width fto be operated upon, in position. After such adjustment, by separatirtgr the rollers as above described, the guides of proper width are put in place.

The abrading wheels, to 33 inclusive, are so positioned, two on each side of the train of rollers, that the will engage the upper and lower corners o each side edge of the belt, as said cornersmove through the paths oftravel of the peripheries of said abrading wheels.

It ,will be `noted from an inspection .of Fig. 2 that the rollers of one unit are in aline which `is offset from the line of the rollers of the other unit, and that the vbelt 67 projects on one side of the rollers of one unit `and on `the other side of the rollers of the other unit so that the edges of the vbelt may be engaged by the abrading wheelson the said projecting sides. It will also be noted from an inspection of Figs. 2 and 4 that certain of the rollers `are recessed sharply from their peripheries on the side from which the vbelt projects in order to receive the abrading wheel which projects into said recess, and thus the abradingwheel is permitted to engage the corner of the jbelt which projects from the side of sai-d recessed roller as indicated in Fig. 4, It will also be noted that the roller cooperating with the recessed roller, projects laterally slightly beyond the side margin or face of-.the recessed roller, in order to support the belt .opposite the corner being abr-aded and to 4prevent belt from bending away from the .abred'ng wheel.

These labra-ding; wheels are so rotated-that fnected by vpipes such :as '63, suction box 64.

may be left, is left on the thin edge of the .a belt. This feather is easily removed by a subsequent operation.

Casings or hoods, such as 62, are fitted over the several abrading wheels and are conwith a suitable What I lclaim is:
