MEANS FOR GROOVING OR SCORING LEATHER Filed April 27', 1929 Patented Sept. 16, 1930 JGEN WILLIAM BABBUBNE, OF RUSHDEN, ENGLAND MEANS FOR GROOVIITG GR SCORING LEATHER Application filed. April 27, 1929, Serial No. 358,673, and in Great Britain April 16, 1929.
This invention relates to means for grooving or scoring leather the means being of the kind comprising series of discs provided with peripheral projections and mounted on a. 5 rotatable shaft for scoring or grooving pieces ofleather, and in particular the bevelled or chamfered margins of soles of footwear, for the purpose of improving toe adhesion between the pieces of leather or soles and the inner soles and uppers of footwear when secured together by an adhesive; and its primary object is to facilitate such grooving or scoring, especially in connection with comparatively thin pieces of leather or soles such as are used for the soles of dancing and similar shoes such. soles being of insufficient thickness to enable them to be effectively held 1 against the grooving or scoring means solely through the body of the leather forming 29 the sole.
' According to the invention, a movable member serves to support the margins or portions of the pieces of leather or soles evenly and closely against the grooving or scora 'ing means. The supporting means not only facilitates the grooving or scoring of-the said margins or portions but also ensures an improved result and obviates injury to the hands of the operator through not having 'topress the margins or portions of the pieces fof "leather or soles against thesaid means with his hands. To further facilitate the grooving or scoring operation there is provided .in connection with the movable supporting member a table on whicn the operator can place the pieces of leather or soles to be operated upon by the aforesaid means. The grooving or scoring means comprise a series of apertured discs of known form provided with teeth or projections and arranger on a spindle capable of being rotated at a a continuous cutting ed e.
to b
an arrangement constructed according to the li us or s iral lines in order to form 'rooves ing the grooving or scoring means comprises It will be understood that the use of such a continuous cutting edge renders unnecessary any finishing operation to the pieces of leather or soles 55 prior to the attachment thereof by an adh sive, as is found necessary in some cases when only toothed discs are employed.
In order that the said invention may be clearly understood and readily carried into effect, the same will now be more fully described by way of example with reference to the accompanying drawings, inwhich:-
Figure 1 illustrates in sectional elevation lzii invention;
Figures 2 and 3 are face views of two forms of discs made use of in the grooving or scoring means. i
The movable supporting means in the construction illustrated in the drawings consists i of a roller or wheel a formed with a bevelled periphery and so arranged relatively to a table 7) that a part of the beveled surface of larger diameter projects through an apei ture Z/provided therefor. The table Z) is inclined at a different angle from that of the bevel of the roller or wheel a, the difference being such that the portion of the roller or wheel a of smaller diameter is always flush at iii) that part where the roller or wheel a extends into the aperture 1), while the portion of larger diameter projects through the aperture and above the surface of the table 6. Above the table band over the roller or wheel a is disposed the grooving or scoring means comprising a series of discs 0 mounted on a spindle (Z capable of being rotated at a high speed through the pulley e. The disc with the continuous cutting edge is designated f and is disposed over the portion of the roller or wheel a of larger diameter. The discs are secured to the shaft between nuts 9 screwed thereon. The roller or wheel a is supported by hanging bearings h attached to the under surface of the table 6. From an inspection of the Figure 1 it will be seen that the discs constituting the grooving or scoring means are so arranged as to produce at the edge of the leather under treatment a bevel some- Q I tween the r oller or Wheel-wand the grooving syor'sco ringmeansis greater at'that part Where the'roller or wheel a 1s ofsmaller d ameter than t the part: of" larger diameter. In 1 thus forming the said space it approximately coreresp ondsfwith the shape, in cross se'ction of the bevelled or chamfered margins of the pieces ofleather or soles.
