Abstract of the Invention An ice skate blade honing device comprising a two part ellipsoidal body member, each part of identical shape, providing a central recess to contain a cylindrical honing stone of one or more grit compositions, the two part body member forming diametrically arranged slots for guiding reception of an ice skate blade for sharpening contact with the honing stone.
Description
~254~42 2196-460 The field of this invention relates to sharpening devices for ice skate blades and for blade-type articles having longitudinal edges or edge faces to be maintained in a sharp condition.
Prior proposed sharpening devices of this nature have included hand-held and bench-held devices in which a sharpening stone was exposed a-t the bottom of a slot provided in a body which received the blade of an ice skate. General examples of such prior devices are found in United States Patents Nos.
546,929; 927,131; 594,723; 2,032,640; 1,006,000; 2,398,566; and 4,219,975. The shapes of the sharpening stones varied from cylindrical to part-cylindrical and part-planar sur:Eaces.
In general, many of the prior proposed sharpening devices were not readily hand-held, that is, the shape of the device dia not comfortably fit the hand of the user, were not readily inexpensively manufactured, some did not provide differ-ent sized grits in the sharpening stone for permitting rough and then fine sharpening of the blade, and some were not readily carried in the pocket of the user so that a blade could be con-veniently sharpened at the ice rink or skating pond.
The present invention provides a sharpening device forice skate blades comprising: an ellipsoidal body including a pair of identically shaped externally and internally configured body parts symmetrical about both a major and minor axis, each body part comprising a generally semi-ellipsoidal external sur-face extending the length and width of the body part, a planar inner surface margin, a generally semi-cylindrical central internal recess along one axis of the ellipsoidal body, said recess having a length less than the length of the body part, and rectangular bosses at each end of the recess on ends of each body part and having abutmen-t faces spaced from the planar sur-face margin adapted to abut corresponding faces on the adjacent B ~*
~S404~ 2196-460 body part; means for holding the body parts in juxtaposed assem-bly with the abutment faces of each part in abutment wi.th the abutment faces of the other part whereby the planar margins define a pair of longitudinally extending slots, each extending for the length of the body and each for receiving a blade edge;
each of said external surfaces including a shallow external recess; a honing stone element having an exposed planar surface received in at least one of said external recesses; and a cylin-drical honing s-tone contained and snugly fitted within the opposed central recesses of the body parts and presenting a con-vex elongated face for sharpening engagement with the blade edge when the blade is inserted into one of the slots and the body and blade are moved relative to each other.
The invention contemplates retaining the body parts and stone in assembly by readily releasable bolt and nut assem-blies and, in one example, the provision of shims to adapt -the width of the -la-3~
~z~ z 58-190/L11.27 slot to various widths or thickness of ice skate blades.
The invention further contemplates the provision of a recess in the external surface oE at least one of the body parts for reception of a flat surfaced honing stone and of identification means on the other of said body parts to indicate ownership of the sharpening device.
The invention contemplates a sharpening device which in its ellipsoidal shape is readily held by the hand of the user and may be readily carried in a pocket o~ provided with attachment means for carrying on a belt.
The primary object of the present invention there-fore is to provide a novel construction of a portable, readily carried, sharpening device for ice skate blades.
An object of the invention is to provide a shar-pening device which i5 constructed to facilitate inex-- pensive manufacture and assembly.
Another object of the invention is to provide a sharpening device which includes means for limiting rocking of the blade relative to the stone about a ~0 lateral axis of the sharpening device.
A further object of the invention is to provide a sharpening device including convenient means to hold the two identical parts of the body in assembly.
Various other objects and advantages of the present 2S invention will be readily apparent from the following description of the drawings in which an exemplary embodiment of the invention is shown.

Detailed DescriRtion In Fig. 1 a sharpening device generally indicated at 10 embodying one example of this invention is shown.
~he device 10 is of a generally ellipsoidal, oviod, or generally egg-shaped configuration and of a length and width to comfortably be held, in use, in the palm of the hand of the user and readily received and carried in a pocket of the user. As best seen in Fig. 2 the device 10 provides an upper slot means 11 and a lower slot means 12 which expose longitudinally extending external surfaces 14 and 15 respectivèly of a honing stone 16 of cylin-drical form. On one external surface 18 of device 10 may be provided mounting means for a rectangular honing stone 19 having a flat surface 20. On the opposite face of device lO may be provided a suitable identification element 21 as later described.
; In further detail and with reference to Fig. 4, the device 10 comprises identical symmetrical semi-ellipsoidal body parts 30, each body part 30 having a generally semi-ellipsoidal external surface 31 and a planar ~nner surface margin 32. The inner surface margin 32 surrounds a generally semi-cylindrical central recess 33 along the major or longitudinal axis o the semi-ellipsoidal bodyO At each end of recess 33 a longi-tudinal rec~angular boss 34 is provided, each boss 34 having an abutment face 35 spaced from the planar margin 32. When abutment faces 35 of the body parts 30 are in juxtaposed abutting relation the bosses 34 serve to define the space between the margins 32 and define the width of the slots 11 and 12. The rectangular bosscs 34 ~5~2 58-190/L11.27 also provide inner faces 36 which define the ends of the semi-cyli~drical recess 33 and which serve to abut and limit l~ngitudinal displacement of honing stone 16 when assembled with the body parts 30.
Means for holding the body parts 30 in juxtaposed assembly with the abutment faces 35 of the bosses 34 of each body part in abutment with the face on the boss of the other body pa~t may comprise a p~ir of nut and bolt assemblies 40 having opposite ends countersunk in the external surfaces 31. Each bolt 40 extends through a port 41 provided in aligned relation in the body parts 30 for threaded engagement with nut 42 for drawing the body parts 30 into snug assembled relation.
The cylindrical hon.ing stone 16 may include a semi-cylindrical portion 44 having a selected grit size forfine sharpening of the blade and a semi-cylindrical portion 45 of a coarse grit-size for initial rough sharpening of a blade. The radius of the semi-cylindrical portions 44 and 45 of stone 16 is approxi-mately the radius of the semi-cylindrical recess 33 so that the stone 16 fits within the opposed recesses with a suitable tolerance to generally firmly contain the stone 16. When as~embled it will be apparent from Fig. 2 that the finer grit 44 is readily accessible through slot 11 for sharpening a blade and the rougher grit 45 is readily accessible through slot 12.
Rectangular bosses 34 may extend across the end inner margins 32 from the end of recess 33 to the external surface of the body part 30. The opposite longitudinal edge faces 47 of each boss 34 lie parallel to the major axis of the body 10 and are spaced apart a distance less than the diameter of the stone 16. When sha.rpening an ice skate blade by placing the blade in the slot 11, for example, the bosses 34 limit rocking of the blade or of the body 10 about a lateral axis so that as the body 10 is moved along a blade, excessive rocking of ~;4~4Z
58-190/Lll.27 the blade is limited by the edge faces 47 at their external ends.
As previously mentioned, on the external semi-ellipsoidal surface of one of the body parts ~0, a recess 50 may be provided to receive and mount a rectangular honing stone 19 of different grit si~e than that provided by the two-part honing stone 16. The rectangular honing element 19 provides a flat planar surface 20 on its external side for suitable flat sharpening of blades or for dressing blade surfaces. The honing element 19 may be secured in the recess by suitable bonding adhesives.
On the other body part 30, a recess 51 of the same configuration of recess S0 may be provided for carrying a suitable rectangular identification element 52 whlch may bear the owner's initials or some other decorative indicia.
- Each of the body parts 30 may be provided with a hole 54 through which may be passed a suitable chain or thong for carrying the device by attachment to the wearer's belt or otherwise.
The shape or form of the device 10 provides a length, width, and depth which may be readily held in the palm of the hand. The external ellipsoidal surface formed by the two body parts is smooth and non-abrasive to the hand. While the honing stone 19 and the iden-tification element 52 have flat surfaces spaced from the external surface of it~ body part, the spacing is minimal and insufficient to cause abrasive skin contact with the edges of the elements 19 and 52. The size and shape of device 10 lends itself readily to carrying of the device in a pocket of the user without awkward bulkiness.
In operation of the device 10 an ice skate blade can be inserted, first, in slot 12 for rough honing of the edge of the blade by moving the device 10 and blade relative to each other for the length of the blade. In such sharpening, the device lO may rock a limited amount ~L2~ 4Z
58 190/Lll.Z7 about a lateral axis with respect to the direction of movement and such rocking is restricted by the opposite ends of the slot as at 60. When the blade edge has been honed by the rough grits 45 of the honi~g stone 16 the device 10 may be turned over so that the edge of the blade may be finished honed by engagement with the finer grits 44 of stone 16. The cylindrical or convex honing surfaces facilitates retaining a hollow ground edge of the blade when the blade has been previously treated to such hollow grinding.
It is sometimes desirable to dress the side edges of the blade. For this purpose the rectangular flat surface medium grit stone 19 may be used by drawing device 10 along the sida faces of the blade.
When the cylindical honing stone 16 becomes worn because of sharpening engagement with a blade at the bottom of the slots 11 and 12, the bolt and -nut assemblies 40 may be loosened so that the honing stone may be turned about its axis to present a fresh honing surface at the bottom of the slot. Such adjustment of the honing stone is usually of infrequent occurence.
The device 10 shows an example of a pair of slots 11 and 12 having a pre-selected width to accomodate the thickness of many ice skate blades. In the event it is desired to use the device 10 to sharpen a blade of greater thickness, shims may be interposed between the abutment faces 35 of the bosses 34. An example of such shims is shown in Figs. 5 and 6 wherein at one end a shim 62 is interposed between the abutment faces 35 of the body parts. Shim 62 is provided with one hole 63 to permit passage of bolt 40. At the opposite end of device 10 which includes ports 41 and hole 54 a shim of the same thickness such as 66 may be provided with a hole 67 and a hole 68, hole 67 permitting therethrough hole 40. Hole 68 coincides with the hole 54 and permits passage there-through of a thong or the like to facilitate carrying the ~;~S4~
58-190/L11.27 device.
The disassembly of device :L0 to insert or remove the shims 62 and 66 is readily accomplished by dis-as6embling the nut and bolt a~semblies 40, withdrawing bolt 40, and removing the shims.
Preferably the device 10 may include shims for wide ice skate blades and a diameter of honing stone which fits the recess 33 as by a slight squeeze fit to prevent movement of the stone about its axis. When a thinn r skate blade is to be sharpened, the shims may be readily removed by disassembling the nut and bolt assemblies 40 and also removing the stone then in the recess. A
smaller stone of smaller diameter may then be substituted for the larger stone so that a similar slight squeeze fit may be obtained with the smaller stone when the body parts are reassembled without shims. It will be, noted that in the -absence of the shims the cross-sectional shape of the recess becomes slightly oval in shape because the transverse or lateral diameter of the recess is reduced by the amount of the thickness of the shims.
The smaller diameter stone is therefore readily lightly gripped by the body parts.
If desirable, small pads may be placed in each recess 33 to more firmly hold the honing stone 16 under shim or non-shim conditions.
The device is of such size and shape that it may be readily carried or worn as an attractive novelty device and may be associated with a keyring or the like. As an attractive novelty device, it will be understood that the body parts 30 may be made of suitable plastic material which may include different solid colors or different mixed colors to provide a noticeable pleasing device.
One body part may be one color, and the other body part a different color, and since each body part is iaentical and symmetrical the assembly of various color combi-nations is readily facilitated.

Prior proposed sharpening devices of this nature have included hand-held and bench-held devices in which a sharpening stone was exposed a-t the bottom of a slot provided in a body which received the blade of an ice skate. General examples of such prior devices are found in United States Patents Nos.
546,929; 927,131; 594,723; 2,032,640; 1,006,000; 2,398,566; and 4,219,975. The shapes of the sharpening stones varied from cylindrical to part-cylindrical and part-planar sur:Eaces.

Detailed DescriRtion In Fig. 1 a sharpening device generally indicated at 10 embodying one example of this invention is shown.
~he device 10 is of a generally ellipsoidal, oviod, or generally egg-shaped configuration and of a length and width to comfortably be held, in use, in the palm of the hand of the user and readily received and carried in a pocket of the user. As best seen in Fig. 2 the device 10 provides an upper slot means 11 and a lower slot means 12 which expose longitudinally extending external surfaces 14 and 15 respectivèly of a honing stone 16 of cylin-drical form. On one external surface 18 of device 10 may be provided mounting means for a rectangular honing stone 19 having a flat surface 20. On the opposite face of device lO may be provided a suitable identification element 21 as later described.
; In further detail and with reference to Fig. 4, the device 10 comprises identical symmetrical semi-ellipsoidal body parts 30, each body part 30 having a generally semi-ellipsoidal external surface 31 and a planar ~nner surface margin 32. The inner surface margin 32 surrounds a generally semi-cylindrical central recess 33 along the major or longitudinal axis o the semi-ellipsoidal bodyO At each end of recess 33 a longi-tudinal rec~angular boss 34 is provided, each boss 34 having an abutment face 35 spaced from the planar margin 32. When abutment faces 35 of the body parts 30 are in juxtaposed abutting relation the bosses 34 serve to define the space between the margins 32 and define the width of the slots 11 and 12. The rectangular bosscs 34 ~5~2 58-190/L11.27 also provide inner faces 36 which define the ends of the semi-cyli~drical recess 33 and which serve to abut and limit l~ngitudinal displacement of honing stone 16 when assembled with the body parts 30.
Means for holding the body parts 30 in juxtaposed assembly with the abutment faces 35 of the bosses 34 of each body part in abutment with the face on the boss of the other body pa~t may comprise a p~ir of nut and bolt assemblies 40 having opposite ends countersunk in the external surfaces 31. Each bolt 40 extends through a port 41 provided in aligned relation in the body parts 30 for threaded engagement with nut 42 for drawing the body parts 30 into snug assembled relation.
The cylindrical hon.ing stone 16 may include a semi-cylindrical portion 44 having a selected grit size forfine sharpening of the blade and a semi-cylindrical portion 45 of a coarse grit-size for initial rough sharpening of a blade. The radius of the semi-cylindrical portions 44 and 45 of stone 16 is approxi-mately the radius of the semi-cylindrical recess 33 so that the stone 16 fits within the opposed recesses with a suitable tolerance to generally firmly contain the stone 16. When as~embled it will be apparent from Fig. 2 that the finer grit 44 is readily accessible through slot 11 for sharpening a blade and the rougher grit 45 is readily accessible through slot 12.
Rectangular bosses 34 may extend across the end inner margins 32 from the end of recess 33 to the external surface of the body part 30. The opposite longitudinal edge faces 47 of each boss 34 lie parallel to the major axis of the body 10 and are spaced apart a distance less than the diameter of the stone 16. When sha.rpening an ice skate blade by placing the blade in the slot 11, for example, the bosses 34 limit rocking of the blade or of the body 10 about a lateral axis so that as the body 10 is moved along a blade, excessive rocking of ~;4~4Z
58-190/Lll.27 the blade is limited by the edge faces 47 at their external ends.
As previously mentioned, on the external semi-ellipsoidal surface of one of the body parts ~0, a recess 50 may be provided to receive and mount a rectangular honing stone 19 of different grit si~e than that provided by the two-part honing stone 16. The rectangular honing element 19 provides a flat planar surface 20 on its external side for suitable flat sharpening of blades or for dressing blade surfaces. The honing element 19 may be secured in the recess by suitable bonding adhesives.
On the other body part 30, a recess 51 of the same configuration of recess S0 may be provided for carrying a suitable rectangular identification element 52 whlch may bear the owner's initials or some other decorative indicia.
- Each of the body parts 30 may be provided with a hole 54 through which may be passed a suitable chain or thong for carrying the device by attachment to the wearer's belt or otherwise.
The shape or form of the device 10 provides a length, width, and depth which may be readily held in the palm of the hand. The external ellipsoidal surface formed by the two body parts is smooth and non-abrasive to the hand. While the honing stone 19 and the iden-tification element 52 have flat surfaces spaced from the external surface of it~ body part, the spacing is minimal and insufficient to cause abrasive skin contact with the edges of the elements 19 and 52. The size and shape of device 10 lends itself readily to carrying of the device in a pocket of the user without awkward bulkiness.
In operation of the device 10 an ice skate blade can be inserted, first, in slot 12 for rough honing of the edge of the blade by moving the device 10 and blade relative to each other for the length of the blade. In such sharpening, the device lO may rock a limited amount ~L2~ 4Z
58 190/Lll.Z7 about a lateral axis with respect to the direction of movement and such rocking is restricted by the opposite ends of the slot as at 60. When the blade edge has been honed by the rough grits 45 of the honi~g stone 16 the device 10 may be turned over so that the edge of the blade may be finished honed by engagement with the finer grits 44 of stone 16. The cylindrical or convex honing surfaces facilitates retaining a hollow ground edge of the blade when the blade has been previously treated to such hollow grinding.
It is sometimes desirable to dress the side edges of the blade. For this purpose the rectangular flat surface medium grit stone 19 may be used by drawing device 10 along the sida faces of the blade.
When the cylindical honing stone 16 becomes worn because of sharpening engagement with a blade at the bottom of the slots 11 and 12, the bolt and -nut assemblies 40 may be loosened so that the honing stone may be turned about its axis to present a fresh honing surface at the bottom of the slot. Such adjustment of the honing stone is usually of infrequent occurence.
The device 10 shows an example of a pair of slots 11 and 12 having a pre-selected width to accomodate the thickness of many ice skate blades. In the event it is desired to use the device 10 to sharpen a blade of greater thickness, shims may be interposed between the abutment faces 35 of the bosses 34. An example of such shims is shown in Figs. 5 and 6 wherein at one end a shim 62 is interposed between the abutment faces 35 of the body parts. Shim 62 is provided with one hole 63 to permit passage of bolt 40. At the opposite end of device 10 which includes ports 41 and hole 54 a shim of the same thickness such as 66 may be provided with a hole 67 and a hole 68, hole 67 permitting therethrough hole 40. Hole 68 coincides with the hole 54 and permits passage there-through of a thong or the like to facilitate carrying the ~;~S4~
58-190/L11.27 device.
The disassembly of device :L0 to insert or remove the shims 62 and 66 is readily accomplished by dis-as6embling the nut and bolt a~semblies 40, withdrawing bolt 40, and removing the shims.
Preferably the device 10 may include shims for wide ice skate blades and a diameter of honing stone which fits the recess 33 as by a slight squeeze fit to prevent movement of the stone about its axis. When a thinn r skate blade is to be sharpened, the shims may be readily removed by disassembling the nut and bolt assemblies 40 and also removing the stone then in the recess. A
smaller stone of smaller diameter may then be substituted for the larger stone so that a similar slight squeeze fit may be obtained with the smaller stone when the body parts are reassembled without shims. It will be, noted that in the -absence of the shims the cross-sectional shape of the recess becomes slightly oval in shape because the transverse or lateral diameter of the recess is reduced by the amount of the thickness of the shims.
The smaller diameter stone is therefore readily lightly gripped by the body parts.
If desirable, small pads may be placed in each recess 33 to more firmly hold the honing stone 16 under shim or non-shim conditions.
The device is of such size and shape that it may be readily carried or worn as an attractive novelty device and may be associated with a keyring or the like. As an attractive novelty device, it will be understood that the body parts 30 may be made of suitable plastic material which may include different solid colors or different mixed colors to provide a noticeable pleasing device.
One body part may be one color, and the other body part a different color, and since each body part is iaentical and symmetrical the assembly of various color combi-nations is readily facilitated.

means for holding the body parts in juxtaposed assem-bly with the abutment faces of each part in abutment with the abutment faces of the other part whereby the planar margins define a pair of longitudinally extending slots, each extending for the length of the body and each for receiving a blade edge;
each of said external surfaces including a shallow external recess;
a honing stone element having an exposed planar sur-face received in at least one of said external recesses;
and a cylindrical honing stone contained and snugly fitted within the opposed central recesses of the body parts and presenting a convex elongated face for sharpening engagement with the blade edge when the blade is inserted into one of the slots and the body and blade are moved relative to each other.
