- 1 This invention relates to'shoe treating machinery employed inroughening the bottom of a shoe preparatory to applying the sole thereto. The apparatus is generally used at the factory` although it may be used elsewhere where a sole is to be applied to a shoe.A

Prior to thecementing or other securing of a sole to a shoe, the bottom thereof is generally roughened, particularly around the edges or margins. For this purpose, the shoe bottom is held against a rotating roughening or abrading wheel. The operator holds the shoe so that its bottom `makes contact with the vrotating wheel, and, in

particular,I he generally holdsv the marginof the f Ashoe bottom against the wheel, rotating it to insure suitable roghening of the entire margin.

-In e'iectng the above mentioned roug'hening A step, operators have generally encountered difculties in suitably maintaining the shoe against the'wh'eel because of the rapid rotation ofthe wheel'and its tendency t'oV displace the shoe in opposition tothe action of the operator. The operator must adjust his own applied pressure inrelation to the tendencyjof the wheel to throw Vthe shoe downwardly, and the roughening action is often quite erratic. The shoe, under the inuence of the diverse or opposing forces may slip from the operators hand since there is no method of holding or guiding it except by the unaided hands of the operator.

With the foregoing in mind. I have devised an apparatus to be used in connection with an abrading or roughening wheel of the type hereinabove described which serves as a stabilizer or guide for the shoe while it is acted upon by the wheel. Such apparatus takes the form of a roller which is'mounted so as to rotate in a' plane perpendicular to the plane of rotation of the roughening wheel and is disposed adjacent to said wheel so that the edge of the shoe bottom may bear against the roller while the shoe bottom is being roughened, the roller permitting convenient and facilitated rotation of the shoe so as to properly treat the marginal edges of the shoe bottom. The roller is arranged to be longitudinally adjustable so that it may accommodate abrading wheels of different sizes or as may suit the convenience of the operator.

The invention will be further understoon from the following describtion and drawings in which:

Fig. 1 is a side elevational view of a shoe bottom roughening apparatus provided with the device of the instant invention.

Fig. 2 is a front elevational View thereof.

Fig. 3 is a fragmentary, enlarged cross-sec- .3 Claims. (o1. 51-102) 1 2 Y tional view as taken alongl the lines"3`-3 of Fig. 2'. y

Fig. '4 is a cross-sectional view as'taken alongy the lines 4-4 of Fig. 3.

The housing IIJ, including thewaste receptacle II, is conventional as is 'the abrading or roughening `wheel I2. Wheel I2 is mounted'for rotation within the housing generally. by a'shaft E S actuated by an electric motor-aswill be'evident to those skilledA in the art. 1 Wheel IZhas an exposed lfront operatingl surface and igenerally rotates downwardly in conventional mechanisms, although, if desired, the wheelmayfrotate upwardly Without interfering with the Soperation of the invention. Y

To the top of the casing I0 is' rst applied Va bracket I3 having a 'substantially upstanding arm I4 formed with sidesrso that' arm I4 ais `channelled -An opening is formed therethrough for vreceiving the threaded shankv .I5 offaset screw I 6 for purposes to be hereinafter described.

' A guidingroller or stop I1 is maintained adjacent to the working surface of wheel I'2.` Roller or stop Il includes a ball bearing as illustrated in Fig. 3 and it rotates in a plane perpendicular to the plane of rotation of wheelv I'2. Bolt .I8 secures roller Il to an elongated arm I9 bya nut 20, a washer 2I being disposed between the roller I1 and arm I9.

In the form shown, the arm I9 is flat and the roller I1 rotates in a plane parallel to the flat surface of the arm I9.

Arm I9 is formed with an elongated slot'22 through which the shank I5 of set screw I 6 penetrates for securing the arm I9 to the bracket 40sapplied and tightened. Arm I9 is received within the edge channels of bracket arm I4 when it is connected thereto so that the yassembly is rendered sturdy and stable. vThe-presence of elongated slot 22 provides for longitudinal adiustment of arm I9 and consequently of roller-I1 so that theroller may be disposed immediately adjacent the wheel I2 or at a height satisfactory to the reouirements or wishes of the operator.

When a shoe bottom is to be roughened around its margins, the operator holds the bottom flatly against the periphery of wheel I2 with the bottom or sole edges in contact with the roller Il which is positioned oiiset from and above the center of the operating surface of the wheel I2 and which, it will be noted, extends past the lower end of arm I9 so as to permit such contact. He then turns or rotates the shoe so that the entire margin becomes roughened by the wheel. During the rotating operation, the shoe bottom edge is always in contact with the roller I1, the roller rotating pursuant to the rotation of the shoe bottom. In this way, the operator is provided with a perfect guide for rotation of the shoe, which guide does not present any resistance pursuant to the operators action in rotating the shoe bottom in a plane parallel to the normal plane of rotation of roller Il'. It is thereafter unlikely that the shoe will fall from the operators hands or will slide about erratical- 1y since he need merely place the bottom, edge against the roller I1 while the wheel l2 is rotating. This will provide such stability and certainty of operation as to result in a more workman-like job performed with greater A,speedand dexterity.

After theshoe bottom Yhas been roughened in this manner, the sole will be applied and secured in conventional fashionto completetheoperation.
