Be it known that I, JEAN Bficm'a, a subject 'of the Kingof Prussia, German Em- Perot, residing at Hiickeswagen, in the Province of the Rhine, Kingdom of Prussia, German Empire, have invented a certain new and useful File, of which the following is a specification. T
--This invention relates to improved files.
- In files with cut teeth the surfaces are too great, whereby too great a pressure in filing becomes necessary. In order to avoid-this the tooth is divided by channels or cro$ cuts. The channels which run parallel to the axis of the file have, however, the drawback that the file so out forms grooves in the article filed, while files cross cut at an angle to the axis of the file occasign a sidewise slipping of the file and likewise the formation of grooves unless the strength of .the workman overcomes this side slip. In order to obviatethese drawbacks, the files according to the presentv invention /are provided with two rows of groovs, one sloping from right to left and the other sloping from left to. right with regard to the centralaxis respectively. Such a construction is illustrated in Figures. 1
and 2 of the accompanying drawings. By this means the side slip is avoided and moreover each single file tooth is sub-divided into parts of various sizes and so there isattained the great advantage that each subdivided file tooth has a difierent division to that preceding it. Any of the work is hereby completely prevented because tooth units of different width are constantly following one another in the filing.
erence will now be made.
Moreover, by this means a decidedly sharper attack is secured with the file.
The accompanying drawings illustrate the invention in four figures to which ref- FILE.

Patented (M2 1913.
' 5 Figs. '1' and '2 are diagrammatic plan views of files indicating by diagonal lines, the directions of the cuts made to produce the notches. Fig. 4 is an edge elevatiomof a portion of a The flat body portion A of the file has primary curved teeth B,-ext ending across the file and parallel to each other.
C indicates the narrow flat surfaces between the rows ofteetha I Each tooth B has a plurality of notches Fig. dis a plan view, and
D; In Fig. 1., the notches are produced by cuts along the lines E, which are spaced apart'approximately the same distance as the cuts along the lines F, while in Fig. 2 the cuts along the lines E are spaced closer together than the cuts along the lines F.
What I claim and desire to secure, is
In a file having a flat body portion, primary curved teeth disposed across said body portion, said teeth having their cutting edges at the top f their vertical faces and at the'innen-fiid. of their curves, said cutgdges also transversely notched so that the notches in one primary tooth will not be in alinementlongitudinally of the file with the notches in thenext succeeding primary tooth and so that the inclination of a part of the notches on one side of the middle I name to this specification in thepresenceof two subscribing witnesses.
