DEVICE FOR SECURING SAWS AND OTHER APPLIANCES TO ARBORS Filed Sept. 5, 1939 Patented Sept. 16, 1941 DEVICE FOR SECURING SAWS AND OTHER APPLIANCES TO ARBORS Robert L. Hcrbst, Hdrtonvillc, Wis., assignor of one-half to Charles J. Steidl, Hortonville, Wis.
Application September 5, 1939, Serial No. 293,459
1 Claim. (Cl. 143-155) This invention appertains to novel means for securing circular saws, grinding and polishing wheels or discs, and the like upon their arbors or drive shafts.
Much difficulty has been experienced in replacing saws, discs, wheels, etc., upon arbors, in view of the fact that the center opening of such saws, discs, etc., are not always of uniform size, and, consequently, when an opening is of a larger size than a shaft, the saw or disc is liable to move off-center.
It is, therefore, one of the primary objects of my invention to provide novel means for properly centering and securing a saw, disc, or other like device upon an arbor, irrespective of the size of the center opening.
Another salient object of my invention is to provide a pair of hub blocks for engaging the opposite sides of the saw or other device to be secured to the shaft or arbor, with a retractible cone carried by one block movable into and out of the center opening of the saw or other device for snugly engaging the wall of said opening, whereby to properly support and center the saw or other device upon the arbor or shaft.
A further important object of my invention is the provision of novel means for mounting the centering cone in the hub block, whereby the cone can be readily moved into and out of the block, and whereby the cone can be held against accidental turning movement after adjustment.
A still further object of my invention is to provide a novel device of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a small cost.
With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing:
Figure 1 is a central section through my device, showing the same utilized for holding a saw upon an arbor, the view being taken substantially on the line l-| of Figure 3, looking in the direction of the arrows.
Figure 2 is a similar view, showing the device utilized for holding a disc upon the arbor having a center opening of less size than the saw shown in Figure 1.
Figure 3 is a fragmentary, sectional view taken on the line 3-3 of Figure 1, looking in the direction of the arrows.
Figure 4 is a fragmentary, enlarged, detail, sectional view taken on the line 44 of Figure 1, looking in the direction of the arrows.
Figure 5 is a detail, side, elevational view of I the centering cone.
Referring to the drawing in detail, wherein similar reference characters designate corresponding parts through the several views, the letter D generally indicates my'improved device for properly centering and securing a circular saw S or similar device upon an arbor A. The arbor or drive shaft A can be of any preferred character or type, and the outer end of the same is threaded, as at I0, for the reception of a clamping nut II. The saw S can also be of any preferred size or character and includes the disc-shaped body l2 having the center opening l3.
My novel device D comprises a rigid hub block [4 and a removable hub block IS. The block I4 is sweated on or otherwise rigidly secured to the arbor or shaft A, while the block 15 is freely removable from the shaft, and this block, in accordance with my invention, is formed with an axial bore l6 opening out into an enlarged,
internally threaded chamber l1. This chamber IT extends out through the inner face of the block, and the adjacent face of the block I around the shaft or arbor A is provided with an axial opening I8.
Adjustably mounted within the chamber I1 is the centering cone IS. The cone is movable into and out of the chamber l1, and the cone can be adjustably mounted in the chamber in any preferred way. As illustrated, the cone can be externally threaded and threaded into the chamber, as by this method a desired fine adjustment of the centering cone can be had. Any preferred means can be employed for rotating the centering cone, and the centering cone can be provided with equidistantly spaced slots 20 for the reception of a suitable tool.
After the cone l9 has been adjusted, the same can be held against accidental displacement in any preferred manner, such as by the use of a key 2! Obviously, the key 2| can be inserted in a keyway 22 formed in the wall of the chamber I! and in one of the grooves 20.
In use of my improved device, when it is de-' sired to replace a saw or other appliance mounted upon the arbor, the nut II is removed from the arbor, which will permit the rapid taking off of the block l5 and the saw. The new appliance is placed against the inner face of the block l5, and
the centering cone is adjusted back and forth according to the size of thecenter opening in the new appliance until the appliance; snugly I seats upon the cone. At this time, the block l5- and the appliance can be ,slid on the arbor A until the appliance butts up against the rigid face of the block [4. At this time, the nut I! Y 'can bethreaded upon the arbor and tightened into intimateengagement with the block 15.
l Obviously, the centering cone will, extend into the chamber [8 formed in the block It.
By the use of my novel device, the saw isv properly supported, and all danger of the saw becoming off-center is eliminated.
1 As' heretofore brought out, variousappli'ancesv other than saws can be properly centered with my device, and in Figure 2 I have shown a disc 25,'"'which can be considered as a polishing disc, and it is to be noted that the center openi'ng 26 of this disc is of a considerably less diameter than the diameter of the opening I3 of the saw.
Consequently, the centering cone [9 is moved a considerable distance back into its chamber I'I', whereby the ported. 7 By having my adjustable centering cone l9, it can be seen that, in effect, I can changethe active diameter of the shaft or arbor A to suit the exact size of the center opening of arcircular saw or other appliance. I
means for holding the movable block in tight contact with the saw or other appliance.
