Description
SAW HOLDING AND CENTERING DEVICE
BACKGROUND OF THE INVENTION
S The present invention concerns a device to hold and center a saw on a saw sharpener or other similar machine.
Many saw-holding or centering systems are known in the industry. Most of these prior art systems use a plurality of magnets to hold the saw in place, which generates several drawbacks. Magnets usually attract dirt since any piece of metal clings to them, and any movement of these magnets displaces the blade of the save which leads to distortions in the blade sharpening.
The present invention provides a saw-holding and centering device without 1S magnets which eliminates the need for constant maintenance, and is in addition simpler and cheaper to build than prior art systems.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a schematic side view of a saw holding and centering device according to an embodiment of the present invention.
Figure 2 is a view from the front of a saw to be held by a device according to the present invention.
Figure 3 is a schematic side view of the device of figure 1 showing an inclined ball and socket joint according to the present invention.

2 DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
Referring to figures 1 and 2, the holding and centering device according to a preferred embodiment of the present invention comprises a support base 5, having a top surface 7 fit to receive a saw 9 thereon, the saw 9 having a central circular opening 10. The base 5 is preferably of circular shape. A plurality of ball-and-socket joints 11 are fixed on said base 5, each having a saw-holding member 13 projecting therefrom in a direction generally perpendicular to the support base 5. Each ball-and-socket joint 11 is held in position by a washer 15. The ball-and-socket joints 1 1 are distributed in a circular manner on the support base 5.
A circular tappet 17 is provided over the base 5, having a diameter slightly larger than the diameter of the circle defined by the ball-and-socket joints 1 1. The tappet 17 is translatable in a direction perpendicular to the base top surface 7, and is preferably fixed on a central shaft 19. A handle 21 is rotationally and threadedly fixed on said shaft 19, in such a manner that rotating the handle allows to push down the tappet 17 toward the base 5 and hold it in position.
The tappet 17 then applies a radial pressure on the saw-holding members 13 of the ball-and-socket joints 1 1, setting said saw-holding members 13 in a position outwardly inclined from the center of the device as may be seen in figure 3.
The saw-holding members 13 of the ball-and-socket joints 11 therefore retain securely in place the saw 9 on the base 5 in a perfectly central position.
The device according to the present invention may in a preferred embodiment be used to hold a saw 9 having a central circular opening 10 provided with ridges 23. The saw-holding members 13 may then be placed to fit in these ridges 23 and hold the saw 9 more efficiently. However, the present invention may be used with a saw 9 having a central opening 10 of any shape, by adjusting the positions of the ball-and-socket joints for this purpose.
Referring to figures 1 and 2, the holding and centering device according to a preferred embodiment of the present invention comprises a support base 5, having a top surface 7 fit to receive a saw 9 thereon, the saw 9 having a central circular opening 10.

However, the present invention may be used with a saw 9 having a central opening 10 of any shape, by adjusting the positions of the ball-and-socket joints for this purpose.
3 Of course, numerous modifications could be made to the preferred embodiment disclosed hereinabove without departing from the scope of the present invention.
