Title: Improvements in twist drill grinding machines
IPC: B24B3/24
Filed: 1951-05-24
Abstract: 693,403. Sharpening drills. ROSENBLOM, K. E. R. May 24, 1951, No. 12211/51. Class 60. A machine for sharpening twist drills comprises a cradle 5, Fig. 2, to oscillate about an axis 3 and carry a grinding wheel 8, and a cradle 27 to oscillate about an axis 25 in synchronism with the cradle 5 and carry means to hold the drill 40 which is also mounted to be swung intermittently about an axis 30, Fig. 3, intersecting both the centre line of the drill and the axis 25 at right angles. The angular movement about the axis 30 is effected manually and in step with the movement of the grinding wheel and is equal to the supplement angle to the drill point. The grinding wheel is driven by an electric motor and supported by a screw-adjusted slide 6 from the cradle 5 which is oscillated by an adjustable-throw crank 15, Fig. 2, bearing on a follower 13 secured to a link 10 pivotally connected to the cradle and a rocking arm 11. The shaft 20 carrying the crank is rotated through worm gearing by a hand wheel 21 and also carries a cam 48, Fig. 3, which through a follower 49 oscillates the cradle 27. A number of axially spaced cams of different configuration may be mounted on the shaft 20, the follower 49 then being adapted for selective engagement with them. Movement about the axis 30 is obtained by providing the drill-holding means with a handle 45 and mounting it on a pivot 29 rigidly connected to the cradle 27. A row of radially-cut notches 47 are engaged by a pawl on the drill-holding means to retain the latter in the correct grinding position. The drill is held between two self-centering, screwconnected jaws 35, 36 one of which is fitted with a replaceable V-shaped member 39. An arm carrying a stop 42, Fig. 4, and a mirror 43 may be swung by a handle 44 to a position opposite the drill point to position the latter. A trace on the mirror indicates the correct angular position for the cutting edge of the drill. The shaft 20 or the cradle 27 may operate an audible or visible signal when the drill is to be swung about the axis 30. Between each of these movements the grinding wheel is advanced by a distance of 0.05 to 0.15 mm. Servo-motors operated by pressure impulses from a synchronised distribution arrangement may be used to operate the machine automatically. Cooling agent from a pump is sprayed over the grinding wheel by a nozzle (not shown).

Title: Improvements in toothed face clutches and method of producing same
IPC: B23F15/06
Filed: 1945-05-23
Abstract: 592,648. Claw clutches. ABBEY, A. (Gleason Works). May 23,1945, No. 12935. [Class 80(ii)] [Also in Groups XXII and XXIII] The driving faces of facially-toothed clutches, for automatic-overload-release or for driving when only partly engaged, are helical and also curved in the radial direction. The radial curvature of the teeth 22 on one member may be convex and on the other concave, as shown, or both may be convex, the radius in each case being different to prevent tooth-contact near the radial ends. The teeth may be helical over their whole depth or only over a chamfered portion near their ends, and are of constant depth. The clutch-teeth are cut (or ground) by successive blades 36 of a circular face-mill cutter (or annular grinding-wheel), which is rotated about a symmetrical (or other) axis 37 (or 37<SP>1</SP>), Fig. 3, parallel to the axis 26 of the clutch-member 22, which latter is rotated uniformly about its own axis as the cutter is fed into and away from it. The inward feed cuts one side face 24a of one tooth, the outward cutting the opposite side face 23a of a tooth spaced symmetrically or otherwise from the first tooth, the work being indexed tooth by tooth until the same side of the cutter finishes all faces. Convex faces are produced by the inside face of the cutter, as shown, concave faces being cut by the outside face of a different cutter. Only the rounded point 49, Fig. 7, of one side of the cutter generates the finished tooth-profile so that the sides 46, 47 need not be accurately dimensioned.
