Description
DRESSING APPARATUS FOR GRINDING WHEELS
FIELD OF THE INVENTION
This invention relates to dressing apparatus for grinding wheels, more particularly grinding wheels utilized in ice skate sharpening machines.
Skate sharpening machines typically provide a jig in which a skate to be sharpened is mounted, and means to traverse the jig along a predetermined path relative to a grinding wheel. Skate blades are usually hollow ground, which requires that the outer perimeter of a grinding wheel rotating in a common plane with the blade is dressed to an appropriate convex profile at an appropriate elevation relative to the blade to be sharpened, although in some cases a flat grind is desired, and provision may be desirable for cross-grinding where recontouring of the blade is required. It has however proved difficult to provide satisfactory arrangements for providing suitable dressing facilities for the grinding wheels used without either increasing the complexity and reducing the flexibility of the machine, or using add-in devices which are difficult to align.
U.S. Patent No. 5,897,428 (Sakcriska) describes a dressing apparatus for use with a skate sharpening machine, in which the dressing tool is held by a dressing arm pivotable between stored and operative position relative to a housing surrounding the grinding wheel and associated with a relative elaborate mechanism for positioning the dressing tool relative to the grinding wheel.
U.S. Patent No. 4,520,788 (Melvin) describes a dresser for precision grinding wheels in which a dressing tool with a flat end is rotatable in a housing.
The housing is magnetically secured to a magnetic table and the table and grinding wheel are adjusted up and down relative to one another.
U.S. No. 4,502,457 (Marron) describes a universal multiple angle workpiece holder with provision for attachment of a dressing tool.
U.S. Patent No. 5,441,449 (Hart) describes a grinding wheel dresser "integratable" with grinding apparatus. The dresser includes a housing surrounding the grinding wheel and support means for positioning the dressing tool, somewhat similar to the Sakcriska apparatus discussed above.
U.S. Patent No. 5,591,069 (Wurthmann) discloses a skate sharpener having a built-in dressing tool. It includes means for positioning the tool and moving it to an inactive position, built into the tool.
A very widely used type of ice skate sharpening machine has a table mounting a grinding wheel for rotation about a vertical axis, and a flat steel worktable on or into which various jigs and templates may be located. A
permanently-installed dressing apparatus, or one which involves substantial installation, is an obstruction or inconvenience to be avoided, if possible.
In a high volume skate grinding facility, more than one sharpening machine may be provided, together with a cross-grinding machine for contouring and rough-grinding, and it would be desirable to provide a dressing apparatus which could be used with all such machines.
According to the invention, there is provided dressing apparatus, for a skate grinding apparatus of the type including a grinding wheel, a worktable for supporting a skate-holding jig for movement over the table along a path determined by templates mounted on or in the table, the grinding wheel being mounted for rotation about a centre spaced a predetermined distance above the table; the dressing apparatus comprising a body having a base with a table engaging lower surface, and releasable means associated with the body for drawing the base member against the table, a horizontal traversing mechanism mounted on the body and at least one tool holder pivotally mounted on the traversing mechanism and supporting a dressing tool for arcuate movement transverse to a plane of rotation of the grinding wheel. The dressing apparatus is, preferably, for use with apparatus having a conventional steel table, and the releasable means is a magnet supported in the body by a lever mechanism for movement between a table-engaging position and a position sufficiently above the table to release the body for movement over the table. The tool holder is mounted on the traversing mechanism for rotation about an axis which is preferably horizontal, and a second tool holder may be provided movable in an arc having a vertical axis.
Further features of the invention will be apparent from the following description with reference to the accompanying drawings.
SHORT DESCRIPTION OF THE DRAWINGS
Figure 1 is a plan view of the dressing apparatus of the invention.
Figure 2 is a side elevation view thereof.
Figure 3 is a perspective view thereof.
Figure 4 is another side elevation view thereof.
DETAILED DESCRIPTION
The dressing apparatus comprises a body 2 having a base ground flat for frictional contact with a flat steel table 4 of a skate grinding machine, whether a sharpening machine with a grinding wheel rotating in a plane which is horizontal and parallel to the table, or a contouring and rough-grinding machine with a grinding wheel rotating in a vertical plane about an axis which is horizontal for cross-grinding. A skate blade to be ground is held horizontally in a jig. Both types of wheel may, in some cases, be mounted on the same table. For reasons that will become apparent, the height of the grinding wheel (the centre plane of horizontal wheels, and the rotational axis of vertical wheels) should be adjusted to the same predetermined level for every machine with which the dressing apparatus is to be used, although the height of a vertical wheel is not very critical.
The body 2 has a straight horizontal keyway 10 machined in its upper surface which is engaged by parallel rails 12 supported on the body 16 of a traversing mechanism. A drive screw (not seen) with a handle or hand wheel 18 at one end is journalled at its ends 14 in the body 16, with the screw engaging a threaded lug (not shown) extending upwardly from the body 2 into the keyway.
The tool holder can be traversed horizontally and incrementally relative to the base by turning the hand wheel 18. Mounted on the body 16 of the traversing mechanism are two tool holders 24 and 26.
The first tool holder 24 has a body 30 rotatable about a pivot pin 28 which extends horizontally through the body 16 of the traversing mechanism and through lugs 32 on the body 30 of the tool holder. Formed on one end of the pin 28 is a projection 8 which can act as a gauge for checking the height of the periphery of a horizontal grinding wheel. An actuating lever (not shown) may be provided on the body 30 to assist in pivoting the body about the pivot pin 28.
A
tool holder arm 36 extends from the body at an angle from the axis of the pivot pin 28 and is provided with intersecting bores co-axial with longitudinal axis of the arm and transverse to that longitudinal axis. A set screw 38 in the co-axial bore, which is threaded, secures the shank of a sleeve 39 into which is screwed a tool 40 having a diamond dressing surface 42 at its outer end, the distance of the surface 42 from the axis of the pivot pin 28 being adjustable by releasing the set screw 28 and moving the sleeve 39 axially. The sleeve may be graduated to facilitate setting the distance between the tool surtace and the axis, Which ultimately determines the radius of a hollow grind applied to a skate. This distance may be adjustable, for example, between 3/e inch and 1'/2 inches. The tool may also be removed from the sleeve and screwed into a bore in the set screw 38. With this arrangement, the distance of the tool surtace from the axis of the pivot 28 is sufficient that radius of a grind applied to a skate blade by a grinding stone so radiused is essentially flat. Although the drawings show separate tools in each of the three possible locations to be described, for reasons of economy, it may be preferred to move a single tool from one location to another, since only one may be used at a time.
The body 22 also carries horizontal arcuate track 43, along which the second tool holder 26 may be moved in a horizontal plane by means of a handle 46 to move a tool 40 having its shank screwed into a socket 50 such that the dressing surface 42 can dress a grinding wheel rotating in a vertical plane on a horizontal axis.
As shown, no vertical adjustment is provided for the centre height at which the dressing tools will contact grinding wheels to be dressed. This height may be, for example, 4'/ inches (slightly higher for a tool in socket 50). All grinding wheels to be dressed by the device should be set at this same height above their associated tables. It would, of course, be possible to provide for vertical adjustment of the tool holders to accommodate different grinding wheel heights, but this requires the height to be adjusted or checked for each dressing operation, delaying operation, reducing precision and increasing the possibility of error.
In order to secure the base to the table 4, a cavity within the body 2 accommodates a powerful magnet 50 with a flat under-surface, which is suspended from a cam 52 on a lever 54 so that it may be lowered onto or raised from the table 4 to lock or unlock the base from the table. Other securing means such as suction cups could possibly be used, but a magnet is believed most satisfactory and durable.
In use, the tool 40 is located, if necessary, in the location appropriate to the type of dressing to be performed on a grinding wheel to be dressed, the sleeve 39 is adjusted, if applicable, to provide a desired radius of hollow grind, and the dressing apparatus is placed on the table so that the surface 42 of the tool is almost touching the periphery of the wheel to be dressed. The body 2 is then locked to the table by engaging the magnet 50 with the table 4. The grinding wheel is placed in rotation, and the tool 40 is fed into the grinding wheel by using the wheel 18 to move the body 16, while rocking the applicable tool holder about the pin 28 or along the track 43.
It will, of course, be understood that the apparatus described is exemplary only, and its construction and details may be varied within the scope of the appended claims.

DETAILED DESCRIPTION
The dressing apparatus comprises a body 2 having a base ground flat for frictional contact with a flat steel table 4 of a skate grinding machine, whether a sharpening machine with a grinding wheel rotating in a plane which is horizontal and parallel to the table, or a contouring and rough-grinding machine with a grinding wheel rotating in a vertical plane about an axis which is horizontal for cross-grinding. A skate blade to be ground is held horizontally in a jig. Both types of wheel may, in some cases, be mounted on the same table. For reasons that will become apparent, the height of the grinding wheel (the centre plane of horizontal wheels, and the rotational axis of vertical wheels) should be adjusted to the same predetermined level for every machine with which the dressing apparatus is to be used, although the height of a vertical wheel is not very critical.
The body 2 has a straight horizontal keyway 10 machined in its upper surface which is engaged by parallel rails 12 supported on the body 16 of a traversing mechanism. A drive screw (not seen) with a handle or hand wheel 18 at one end is journalled at its ends 14 in the body 16, with the screw engaging a threaded lug (not shown) extending upwardly from the body 2 into the keyway.
The tool holder can be traversed horizontally and incrementally relative to the base by turning the hand wheel 18. Mounted on the body 16 of the traversing mechanism are two tool holders 24 and 26.
The first tool holder 24 has a body 30 rotatable about a pivot pin 28 which extends horizontally through the body 16 of the traversing mechanism and through lugs 32 on the body 30 of the tool holder. Formed on one end of the pin 28 is a projection 8 which can act as a gauge for checking the height of the periphery of a horizontal grinding wheel. An actuating lever (not shown) may be provided on the body 30 to assist in pivoting the body about the pivot pin 28.
A

A set screw 38 in the co-axial bore, which is threaded, secures the shank of a sleeve 39 into which is screwed a tool 40 having a diamond dressing surface 42 at its outer end, the distance of the surface 42 from the axis of the pivot pin 28 being adjustable by releasing the set screw 28 and moving the sleeve 39 axially. The sleeve may be graduated to facilitate setting the distance between the tool surtace and the axis, Which ultimately determines the radius of a hollow grind applied to a skate. This distance may be adjustable, for example, between 3/e inch and 1'/2 inches. The tool may also be removed from the sleeve and screwed into a bore in the set screw 38. With this arrangement, the distance of the tool surtace from the axis of the pivot 28 is sufficient that radius of a grind applied to a skate blade by a grinding stone so radiused is essentially flat. Although the drawings show separate tools in each of the three possible locations to be described, for reasons of economy, it may be preferred to move a single tool from one location to another, since only one may be used at a time.
The body 22 also carries horizontal arcuate track 43, along which the second tool holder 26 may be moved in a horizontal plane by means of a handle 46 to move a tool 40 having its shank screwed into a socket 50 such that the dressing surface 42 can dress a grinding wheel rotating in a vertical plane on a horizontal axis.
As shown, no vertical adjustment is provided for the centre height at which the dressing tools will contact grinding wheels to be dressed. This height may be, for example, 4'/ inches (slightly higher for a tool in socket 50). All grinding wheels to be dressed by the device should be set at this same height above their associated tables. It would, of course, be possible to provide for vertical adjustment of the tool holders to accommodate different grinding wheel heights, but this requires the height to be adjusted or checked for each dressing operation, delaying operation, reducing precision and increasing the possibility of error.
In order to secure the base to the table 4, a cavity within the body 2 accommodates a powerful magnet 50 with a flat under-surface, which is suspended from a cam 52 on a lever 54 so that it may be lowered onto or raised from the table 4 to lock or unlock the base from the table. Other securing means such as suction cups could possibly be used, but a magnet is believed most satisfactory and durable.

The grinding wheel is placed in rotation, and the tool 40 is fed into the grinding wheel by using the wheel 18 to move the body 16, while rocking the applicable tool holder about the pin 28 or along the track 43.
It will, of course, be understood that the apparatus described is exemplary only, and its construction and details may be varied within the scope of the appended claims.
