Application filed September 21,1927.
This invention relates to cutter-headsfor wood working machines, such as planers, or the like. V p The object of the invention is the improvement of cutter-heads of this character with. a view to increase its elliciency and reduce the cost of manufacture.
more specific object is to provide a cutter-head which is adapted forthe use of narrow cutter blades, and which is provided with means for rigidly holding the blades in adjusted positions.
Another specific object is to provide a cutter-head with means which will enable the blades being firmly clamped to the body of the head in close proximity to the periphery thereof.
Other specific objects and advantages of the invention will description.
The invention consists in the novel construction, adaptation and, combination of parts hereinafter described and claimed. 7 v
In the accompanying drawing,- Figure 1 isa view partly in end elevation and partly in transverse section of a cutterhead embodying my improvements; Fig. 2 is Fig. 3 isa perspective View of a cutter-blade; Fig. 4 is a perspective view of a seat strip; and Fig.
'5 1s a perspect' ve View of a blade-clamping strip; the elements illustrated in Figs. 8, 4 1 and 7 being shown detached from the head.
present invention, a a cylindrical body 10, of steel or other suitable material, having circumferentially spaced apart longitudinal slots located between 11 and 12, of the body 10. H
Said. slots are disposed somewhat tangentially of the body, each slot being formed with a rear portion extension than the front portion which terminates at a bottom seating surface 14 which is disposed at right angles, or nearlyso, with respect to the slot surfaces ofthe re spective walls 11 and 12. Provided in the rear portion 13 of a slot and extending outside of the plane of the surface 14 is a metal strip 15 whIich is)provided with'a reentrant (dg. 4 its sides 17 in the plane,preferably, with the i e respective recess According to the strip 15.
inner rear corner,
clamp them one appear in the following,
For each-slot rear side and is of a thickness equal to the thicknessof the reduced 22. represents a blade clampingstrip, one for each slot, and is adapted to have its reentrant angle 16 againstthe outer side surface portion21 of the strip. 1 7
he rear surface of the clamping-strip is adapted to bear against acutter blade to the same against wall 11. To effect the clamping function of a strip 22- there is provided for each of or more set screws 24, three being shown in Fig. 2, taking in'threadedholes, as 24 provided in the respectice bodyjwall l2 and extending from recesses 25 into which the respective screw heads 26 are sunk interiorly head.
The set screws 23 are approximating with respect to-the plane of the respective cutter blades, and to afford suitable bearing surfaces stripsyeach of the latter of the reduced front side to videthe bearing surface 28 above referred to. I l I As shown in Fig. 5 the reentrant angle of aclamping strip extends the entire length of the same to enablethe strip to be located at selected positions lengthwise of the, body 10 to ac'con'imodate the positions ofathe set screws for different lengths of cutter blades and with respect to different endwisc loca tions of theblades, 7
he outersurface of each clamping strip s. prov ded with a concave groove 29, the arc of which extends to the edge 30 which abuts breakers.
the clamping strips to serve as chip machines it In planers for wood working is important that the planer blades be rigidly secured in their adjusted positions to the body, or cylinder, of the head. This Is accomplished inthe present invention by.
means of the clamping strips 22 eachhaving portion 21 of a I or heel, 23 fit within the of a seat strip 15 andthe respective body disposed at an angle I is provided'a narrow cutting I of the cutting circle of the cutter I upon the clamping is forined'with a proreentrant angles Within which lit the clampino' strips.
3y the provision of a groove 27 in a clamping-strip of the entire length of the strip, short strips may be used with short blades and located in most advantageous positions for holding the blades.
What I claim, is,
'1. A cutter head provided With a groove having a side-Wall provided with a seating surface, and screw threaded holes extending through the opposite Wall of the groove, a cutter blade, a narrow strip, a clan'iping nieniher adapted to bear along its opposite edges against the cutter blade and strip respectively, and screws engaging in said holes for regulating the clamping member for securing both the cutter blade and the strip to the cutter head.
2. A cutter-head for Woodworking niachine, comprising a cylinder having a longitudinal groove, a cutter-blade, a seating strip having a reentrant angle to providethe strip with an edge portion of approximately the thickness of said cutter-blade, a clainping strip having in one of its sides a groove extending longitudinally thereof, and a plurality of set screws extending through threaded. holes provided in one of the Walls of the groove of said cutter-head and into engagement with the clamping strip Within the groove of the latter, said screws serving to cause to cause the clamping strip to bear against the reduced portion of said seating strip and against the cutter-blade to clamp the latter against the other wall of the cutter-head groove.
