METALWORKING TOOL-MEANS FOR CONNECTING THE CUTTER TO THE HOLDER Fiied June 27, 1936 2 sheets-sheet 2 Inventor By/.-M 'Attorney y Patented Oct. 1.3, 1936 TOOLS-MEANS FOR THE CUTTER T0v THE` My invention relates METALWORKING coNNEoTlNG HOLDER orties Emil Gairing, Detroit, Mich., assignor to The Gairng Tool Michigan Company, a corporation of Application June 27, 1936, Serial No. 87,727 s claims.v (orgie-93) to metal -working tools, means for yconnecting the Figure 1 is a plan v adjacent to the drivin iew of the assembled tool g lugs, the upper wall ofv the holder and one of its driving lugs and the upper portion of the locking pin being cut away as indicated in Figure 2,
by the straight lines ing lugs at right angles to the axis ofthe tool.
Figure 3 is a plan and sectionalview of, the
assembled tool, taken on or about Y the broken and straight arcuate lines III-III, of Figure 4,
Figure 4 is a cross- Figure 2, showing the position.
Figure 5 is a detail or the shank and lugs of the the holder.
Figure 6 is a plan sectional view, similar to parts in another relative oss-sectional View through view showing the shank of the cutter, which nts into a corresponding socket Y in the holder.
Figure 7 is a detail wall of the holder sho its operating mechanism.
Figure 8 is a detail section of a part of the wing the locking pin and view of a 'portion of the wall of the socket of the holder looking outwardly as indicated by the arrows, showing the shape of the slot in which the locking pin reciprocates lengthwise of the tool.
The numeral 2 denotes the holder having the usual cavity or socket,
shapedj to receive' and co-act with the shank of the cutter. r'Ihe numerals 3-33 are driving lugs extending inwardly from the wall of 120 to each other.
of the holder atan angle The numeral 4 designates the cutter provided with outwardly extendi spaced 120 apart and the lugs 3 3-3, when ng lugs 5-5-5, angularly adapted to come between engaged in the holder.
The lugs 3 and 5 are rectangular in crosssection,-have radial faces-and are of a circumferential extent that will permit considerable free relative movement of rotation.
The numeral 6 denotes a cavity extending inwardly from the middle of a driven of the lugs 5, and (a designates an inner end of inner end of the socket face of each offset at the said cavity on the side toward the of the holder.
The numeral l indicates a slot extending radially into the wall of but not through said the socket of the holder Wall, and the numeral 8,
a bore extending into the wall of the holder from thel edge'at its outer end, and parallel to the axis thereof. The axis of the bore intersects that of the slot 1, at right angles.
The numeral 9 denotes a smaller bore coaxial with the bore 8, extending radially from the cavity'l, opposite to the bore 8.
'I'he `cavity, T is semicircular at its ends and islonger than wide, as shown most distinctly in Figure 8. KK
. The numeral I6, denotes a pin fitting adapted to reciprocate longitudinally in the slot l, and extends radially intorthe socket of the holder. The pin has a transverse aperture formed therethrough'as shown in broken lines in Figure 8.
The numeral Il indicates a pin having a head Ha, adapted to t The numeral I2 denotes a coil pressure spring in the bore 8, the numeral i2a denotes a screw-threaded plug in the outer end of pressing said head against the pin l0 and forcing the latter toward the inner end of the slot 1.
and when said pin is opposite l engage in said offset at its inner end, said pin" the onset 6e, it is forced into the same by the action of the spring I2.
The pin VII) is adapted to reciprocate freely on the shank I Ib of the pin I I.
