The shafts 21 carry stropping or means for axially rotating the grinding or grinding media, which may be of leather or stroppingmedia; other suitable'material, adapted to engage Fig. 7 is a s de view illustrating the drivth tti d a f an mid t b mg meai s of Fig. 6; stropped, such as a. strip of steel A, which Fig 8 IS a detail of gui ing means for the may be utilized for safety razor blades. We material to be stropped; have shown each of theshafts 21 equi-dis- FlgS- 9 an 1 are Sect/101181 fif P8- tantl'y dis osed respecting the axes of the tively on lines 9, 9 and 10, 10 of Fig. 8; and correspon ing shafts 9 and 13, the shafts 21 F g. 10 IS a cross-section of strip-A. being provided with rolls 22, secured to said Similar numerals of reference. indicate shafts by ins 23 or in an other desired corresponding ,parts in the several views. manner. aid rolls are s own provided with spirally disposed peripheral grooves 2a in which are located the media before referred to, such as strips of leather or other suitable material 25, (Fig. 2), whereby said strips are helicallydisposed around the rolls 22 and have their outer surfaces exposed to engage the cutting edge a of the strip A. The strips 25 may be secured in the peripheral recesses 24 of rolls 22 by anysuitable means, such as by an adhesive. The strips 25 may be of suitable material adapted to grind or reduce the edge a by contact therewith, or have a grinding substance applied thereto such as ground emery, in any suit able way, or said strips may be of leather, canvas or the like, relatively smooth on the working surface, to serve for stropping or honing edge a of strip A. During the rotation of shafts 9 and 13, by means of the gearing before described, the rolls 22 are rotated bodily around; the axes of their shafts 9, 13, with respect to the strip a passing between them, so that the outer surfaces of the media or strips 25 may engage the sides of strip A or its edges a. lit will be observed from the drawings that the respective sets of stropping rolls are located on opposite sides of the strip .d,, which is guided to travel longitudinally through a guide 26 which may be supported in vertical slots 3' of the standards 3, screws 27 carried by said standards serving to adjust the guide 26 in an upward direction and retain the guide in set position, (Figs. t and 5). lhe guide 26 may be of any suitable construction having an upper interior space 26 to receive strip A, (Fig. 9). The guide 26 is shown formed in two'pieces of metal secured together by screws 29 and provided with longitudinally disposed odset portions 26 which oppose and provide the guiding recess 26, (see Figs. 8, 9 and 10). Uentral guiding members 26 are set relatively close together to receive strip A between them at the portion where the grindingor stropping is performed, and secured to guide 26, (Figs. 8 and 10).

In the example illustrated in Fig. 1 the rolls 22 at the ri ht hand side are adapted to be rotated bodily clockwise, in the direction of the arrow 6, and the rolls 22 at the i left in said figure are adapted to be rotated row 0, and said rolls on bodily anti-clockwise, in direction of the aropposite sides of the machine are shown so disposed as to alternately engage the edge a of strip A as said rolls rotate bodily. Means are also provided to rotate the rolls axially while they are being bodily rotated around the axes of their respective supporting shafts 9 andld, so the stropping media or strips 25 willnot only engage the strip A by reason of their bodily rotation, but also by reason of tlldll ttfilal rotation, as in a lanetary manner. For producing the axia rotation of rolls 22 we prothat near/n74 vide said rolls with pulleys 30, which may be secured to the respective shafts 21, which pulleys are adapted to engage an endless belt 31v during bodily rotation of said pulleys with their respective rolls, (Figs. 6 and 7). The endless belt 31 passes from a drive pulley 32 over guiding pulleys 33 on opposite sides of the machine, and has-bights or loops 31, 31* above said pulleys which re-- spectively enclose some of'the pulleys on opposite sides of the machine, said belt at its portion below said bights or loops also passing over guide pulleys 34: on opposite sides of the machine (Figs. 3 and 7). The pulleys 33, 34 are arranged in pairs and are carried upon shafts or pivots 35 supported by arms 36 projecting outwardly from the frame 2. The belt 31 is driven in the direction of the arrows in- Fig. 6 by means of pulley 32, and as the pulleys 30 are rotated bodily around the axes of their shafts 9 and 13 and make contact with the respective bights of the belt 31 said pulleys are rotated axially respectively in the direction of the arrows at and e in Fig. 6, that is to say the pulleys and their rolls 22 are rotated axially clockwise on one side of the machine, as on the right hand side of Fig. 6, and axially anti-clockwise at the left hand side of Fig. 6, whereby the stropping media or strips 25 will be rotated correspondingly in contact with the opposite sides of strip A, in a direction toward the cutting edge of the strip. By adjusting the arms 14:, 15 toward the cutting edge a of strip A the 'stropping or grinding media or strips 25 not only engage said edge of strip A with a so-called wiping stroke by reason of their bodily rotation, -but also with a relatively sliding action against such edge by reason of their axial r0- tation and their helical or spiral action against said edge.

The pulley 32 may be driven in any suitable way, being illustrated mounted upon a shaft 37 journailed in suitable bearings on the main frame to be driven in any suitable manner. The belt 5, for the drive pulleys 5 and 6, is adapted to operate on fast and loose pulleys 38, 39" on shaft 37, whereby shafts i and 37 are rotated together.

The strip A may be fed between the respective sets of rolls 22 in any suitable manner, such as from a reel B on one side of the machine to be pulled by drawing rolls C on the other side of the machine. Our 1m; provements may be incorporated in any desired or well known machine adapted to first grind the edge a of strip A to reduce the cutting edge a to any desired condition before being operated upon by the described stropping or honing devices, or the grinding may be performed in one machine and the stropping or finishing in a separate machine.

While we have illustrated sets of rolls 22 on opposite sides of the machine, adapted to V bodily at, one

the medium, the said bodily tions of said rubbing member being consuccessively or alternately operate on opposite sides of the edge of strip A, it will be understood that where the cutting edge of astrlp is to be gIOllIlCl or stropped only on one side thereof, only one set of the rolls 22 need be used to operate on the corresponding side ofthe strip.

From the foregoing description it will be understood that as the strip A advances adjacent to the rolls 22 the-latter will be rotated bodily as well as axially in contact with the edge portion of the strip, and that the grinding or stropping media 25 will continue to engage the cutting strip with alternate successive touches from the corresponding series of rolls 22, so that as the strip advances along said I rolls the same part of,

'thestrip willbe successively'engaged by succeeding media 25, whereby a very fine and delicate edge may be produced upon the strip in an accurate and expeditious ma1iner. The rolls 22 may be used in our machine to first grind the strip A for an edge and then strop it, spaced sets of rolls being provided for such purpose, or the rolls may be arranged to grind or to strop only as may be desired.

The finished strip may be divided into shorter lengths for any desired purposes, such as for razor blades. Instead of passing a strop through the machine for grlnding, stropping or honing its cutting edge a strip of suitable length may be placed in the guide or holder 26 to be ground or stropped while held stationary, to be removed and replaced when finished, and so on successively. 1

We term the strip or strips 25 a rubbing medium or media whether adapted for grinding or stropping the material or strip A since, as such medium passes said material or strip it will engage the same with a rubbing action. Although we have shown the medium 25 in the form of astrip spirally disposed on its roll 22 it will beunderstood that said medium may be in any other deisired form adapted to engage material when passing the same.

Having now described our invention, wha we claim is v 1.
