CUTTER HEAD AND BIT [n We@ 07' en?? fTa/Zoys Patented May 2, 1933 vUNITED STATES ramos PATENT A OFFICE HENRY H. TALBOYS, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO NORIDBERG MANU- FACTURING CO., 0F MILWAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN CUTTER HEAD AND BIT ApplicationV led June 29,

My invention relates to an improved cutter or cutter head and has for one purpose the provision of improved means for adjustn ably securing a cutter or a cutter head. Another object isV the provision of improved means for adjusting cutting elements.

Other objects will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein VFigure l is an elevation of an adzing device to which my cutter head and cutter have been applied;

Figure 2 is a top plan view of the cutter head with cutters in place;

Figure 3 is a section onv the line 3-3 of Figure 2; Y

Figure 4 is an enlargement of a portion of Figure 3;

Figure 5 is a section on the line Figure 4;

Figure 6 is a view of a cutter receiving member; and

Figure 7 is a view of an individual cutter.

Like parts are indicated by like symbols throughout the specification and drawings.

I have illustrated my invention as applied to an adzing machine but it will be realized that this is but one of a number of applications which may be made of it.

Referring to the drawings, A indicates a railroad track tie carrying the rail A1.

B indicates generally the transverse frame of an adzing machine, upon which is mounted any suitable motor B1 with a drive wheel B2. B3 is a belt passing about the pulley B4E which rotates the shaft B5.

C is anyv suitable supporting wheel or wheels upon which-the transverse frame B is mounted. The rollers C1 prevent lateral movement of the wheel C in relation to the rail A1.

I) indicates any suitable counter balance or poise adapted to maintain the center of mass of the entire device along an axis generally aligned with a rail A1. The operator may employ the handle'l)1 to thrust the outer end of the frame downwardly but preferably the weight Dis sufHci-ent to hold 1931. serial No. 547,47a`

'the Outer end of thermale B tarea upwardly away from the tie.

E generally indicates a cutter head mounted on the lower end of the shaft B5, and rotated in response to rotation of the drive wheel B2. The cutter head E may yinclude the hub E1, web portions E2 and radial ribs E3 associated with theV webs E2. The webs E2 are recessed or cut back as at'Et adjacent 'tudinal movement is prevented. by the upper Its forward face is and lower flanges G1; channelled as at G2 to receive the longitudinally extending rib G4 of the cutter member G3. It will be seen, as in Figure 5, that the cutter member is of substantially greater length than the abutment G.

H indicates a clamped member having a flange I-I1 conformingvand penetrating the aperture E7. At its opposite end or edge vit is provided with a frame portion H2 opposed to the outer face of the cutter G5. n Cates aflock bolt passing throughthe aperture I-I4 ofthe member E5. It is provided Vwith a head H5 which engages the face of the member E5 opposite to the apertures EB and Ef The bolt I-I3 also passes through an aperture H5 inthe member H. Washers H7 and a nut H8 may be employed to lock the parts in theV position in which they are shown in Figures 4 and 5, with the lower cutting edge G10 of the cutter VG3 in cuttingl position. The cutter is made reversible, with cutting edges lat top and bottom. Vhen reversal is desired, or longitudinal shifting of the cutter G3, the nut H8 may be slacked and the-cutter G3 moved or reversed.

It will be realized that whereas I have Vdescribed and shown a practical and operative device, nevertheless many changes may be made in size, shape, number and dispositionV of parts without departing from the spirit of my invention. I, therefore wish,

H5 indiy the embodiment of my invention hereinv shown, is employed to adze railroad ties. The head is rotated about a generally vertical axis, which, at the saine time moved along the track, thus adzing a flat bottomed depression to receive the base flange of the4 rail. The individual cutters G3 are preferably set to a uniform cutting plane perpendicular to the axis of rotation of the head. In adZing an old device it oftenvrhap-V pens that pieces of metal are left in the ties, such as the Shanks of old railroad spikes. The life of the individual cutter member is, therefore, short, and I wish to provide for quick and easy adjustment, reversal or replacement. In effect drawing up on the nut H8 rotates the clamp lmember H about an axis adjacentthe engagement between the portion H1 with the aperture or depression E?. Y The end H2 is powerfully thrust against the cutter G3; The cutter is prevented from twisting by the rib Gt which engages the abutment Gr. rvThe abutment is positioned by the flanges G1 and is prevented from twisting by its seat in the depression A relatively slight loosening of the nut H8 permits the cutter G3 to be slid'up or down or to be removed altogether for reversal or replacement. The abutment member Gr, however, is kept in place even when the cutter is removed from between it and the portion I-I2 of the clamp member.

I' claim: y

1. In a cutter head,l a rotatable head member disposed in a.A plane transversely of the axis of rotation of thehead, and provided with a cutter receiving face portion lying in a plane substantially parallel to the axis of rotation, said face portion being provided with radially spaced recesses extending substantially parallel to the axis of rotation, a cutter abutment positioned in one of said recesses and restrained thereby from radial motion in either direction, and carrying parts interlitting with said headto hold the abutment against lateral and longitudinal movement with respect to the head, a

cutter member contacting theexposed face of the abutment, and extending transversely of the plane of the head substantially parallel to the axis of Vrotation thereof, the contacting faces of the cutter and abutment being provided with longitudinally extendinginteritting parts, a clamping member having a portion engaging the exposed face of the cutter to urge the cutter into engagement with the abutment, said clamping member carrying a flange seated in another of said recesses in the face portion of the cutter head, and a bolt member penetrating the face portion of the cutter head and said clamping member intermediate said recesses for securely drawing said clamping member int-o engagement with the cutter whereby to retain the parts in operative position on the cutter head.
