SPIDER CONSTRUCTION FOR STALK CUTTERS F iled Oct. 1, 195a I -T. E-J 3 Patented Dec. 28, 1937 UNITED STATES SPIDER, CONSTRUCTION FOR STALK CUTTERS Lloyd J. Taylor, Wichita. Falls, Tex.
Application October 1, 1936, Serial No. 103,539
1 Claim.
This invention relates to stalk cutters and it has particular reference to a spider construction for a bladed rotary stalk cutter.
The principal object of the invention is to provide, as a new article of manufacture, a spider construction, cast in a single piece, for receiving the blades of the cutter and due to such construction, several advantages accrue such for example, as added strength and ability to resist unusual shocks and strain transmitted to the spider by the blade; longer periods of usefulness and greater economy in manufacture.
The invention further aims to provide a spider of the character specified whose blade receptacles or recesses are so disposed radially and relative to the rotating axis of the spider that the blades when in position will also be radial relative to such axis. Accordingly, any strain on the cutting edges of the blades will be met by the solid'resistance of the center mass of the assembly.
With the foregoing objects as paramount, the invention has other and lesser objects as well as certain salient features of construction, to become manifest as the description proceeds, taken in connection with the accompanying drawing, wherein:-
Figure 1 is a side elevation showing an example of the spider assembly and its use, and
Figure 2 is a transverse section on lines 2-2 on Figure 1.
Continuing with a more detailed description of the drawing, reference is primarily made to Figure 2 which shows a transverse section of the cutter complete but an elevation of. one of the spiders, constructed according to the invention.
It will be observed in this figure that the ar ticle is constructed with a view of making it easy to remove from the mold, after being cast, yet without sacrificing any of its strength and durability in actual use. Each spider is composed of a hub l with integral, radiating arms or projections 2. The ends of the hubs are outwardly tapered, as shown, to insure ready removal thereof from the mold.
Each of the arms 2 is provided with a recess 3, one wall of which is alined with a line extending radially from the rotating axis of the shaft 4,
upon which the spider is mounted and secured by set screw 4*. The opposite wall of the recess 3 is relatively at an angle. This construction is desirable first, as a means to insure a clean casting and to effect its ready removal of the casting from the sand and second, to enable the blade 5 to be inserted into the recess without difficulty. Moreover, since the recess 3 has one wall in radial alinement with the axis of the mounting shaft 4, so also is the operative face of the blade disposed, 10 due to the fact that'the straight wall of the recess affords an abutting surface for .the blade and against which it is rigidly secured by bolts 6,
passing through apertures provided therefor in the extremities of the arms 2. 15
Thus it will be seen that not only is there suificient stock forwardly of the operative surface of each blade to resist any undue strain imposed thereupon but the lip I likewise serves to rigidify the blade and relieve the bolts 6 of much of the strain imposed thereupon. Moreover, due to the radial alinement of the blade surfaces with the rotative axis of the spiders, the Weight of the mass is greatest, with the least possible strain on the casting when the blade is under maximum 25 pressure or in a position to cut a stalk or other substance.
Manifestly, the construction shown and described is capable of some modification and such modification as may be considered within the scope and meaning of the appended claim is also considered within the spirit and intent of the invention.
What is claimed is:
As a new article of manufacture, the combination in a spider casting for rotary stalk cutters comprising a tapered hub portion receivable on a .shaft, a series of radial arms, each being bifurrelative to said abutting wall and means for secur- 45 ing said blade in said recess.
