Apparatus for cutting a sausage product

An apparatus for cutting a sausage product has an elongate, generally cylindrical housing and a generally annular cutter member. The housing has an axis, a circumferential side wall with radial inner and outer surfaces, and first and second axial ends. The housing defines a cutting chamber sized for receiving the sausage product, and the side wall includes a plurality of elongate, generally parallel axial slots extending therethrough. The slots are generally equally spaced from each other around the circumference of the side wall. The cutter member has an axial length and a curved inner circumferential surface with a diameter at least slightly greater than that of the outer surface of the housing side wall. The cutter member extends around and is coaxial with the housing, and includes a plurality of generally radially inwardly extending blades, where the blades are spaced from each other around the circumference of the cutter member so that each blade is generally aligned with and extends through one of the housing slots and into the cutting chamber. Accordingly, axial movement of the cutter member with respect to the housing results in a plurality of generally parallel axially extending cuts being made into the sausage product located within the cutting chamber.

FIELD OF THE INVENTION 
The present invention relates generally to an apparatus for cutting hot 
dogs and similar sausage food products. More particularly, the present 
invention relates to an apparatus for cutting a hot dog such that a 
bitten-off or severed section breaks into several small pieces or 
segments, thereby reducing the risk of choking. 
BACKGROUND OF THE INVENTION 
As is known, eating a hot dog or other similarly shaped food product can be 
hazardous to small children and others. In particular, if an individual 
bites off a piece of the hot dog, fails to sufficiently chew the 
bitten-off piece, and then attempts to swallow, the piece may block the 
airway of the individual and result in serious injury or even death. 
Accordingly, a need exists for a product that lessens such risk of 
blockage. 
As is also well known, a hot dog or other similarly shaped food product is 
typically formed with a skin or skin-like exterior and has a straight, 
elongate shape. When cooked, such hot dog swells, and the swelling may 
cause the exterior to rupture. If such a rupture occurs, the shape of the 
hot dog may become distorted and bent out of the straight, elongate shape. 
Such a distorted hot dog is aesthetically unpleasant and visually 
unappetizing. 
To prevent such a rupture, the hot dog may be held by hand and the exterior 
of the hot dog may be slit by a knife or other sharp object. However, the 
use of such knife is inherently dangerous since the knife can easily slip 
from the hot dog and cut the hand and/or other body parts. Accordingly, a 
need exists for a product for safely slitting such hot dog. 
SUMMARY OF THE INVENTION 
The aforementioned needs are satisfied by an apparatus for cutting a 
sausage product where the apparatus has an elongate, generally cylindrical 
housing and a generally annular cutter member. The housing has an axis, a 
circumferential side wall with radial inner and outer surfaces, and first 
and second axial ends. The housing defines a cutting chamber sized for 
receiving a sausage product, and the side wall includes a plurality of 
elongate, generally parallel axial slots extending therethrough. The slots 
are generally equally spaced from each other around the circumference of 
the side wall. 
The cutter member has an axial length and a curved inner circumferential 
surface with a diameter at least slightly greater than that of the outer 
surface of the housing side wall. The cutter member extends around the 
housing to be generally coaxial therewith. The cutter member includes a 
plurality of generally radially inwardly extending blades, where the 
blades are spaced from each other around the circumference of the cutter 
member so that each blade is generally aligned with and extends through 
one of the housing slots and into the cutting chamber. Accordingly, axial 
movement of the cutter member with respect to the housing results in a 
plurality of generally parallel axially extending cuts being made into a 
sausage product located within the cutting chamber.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
Certain terminology may be used in the following description for 
convenience only and is not limiting. The words "left", "right", "upper" 
and "lower" designate directions in the drawings to which reference is 
made. The words "inwardly" and "outwardly" are further directions toward 
and away from, respectively, the geometric center of a referenced object. 
The terminology includes the words above specifically mentioned, 
derivatives thereof, and words of similar import. 
Referring to the drawings in detail, wherein like numerals are used to 
indicate like elements throughout, there is shown in FIGS. 1-5 an 
apparatus 10 for cutting a hot dog 12 or the like constructed in 
accordance with a preferred embodiment of the present invention. It should 
be understood that all references to the term "hot dog" should be taken to 
mean any and all cylindrical elongate sausage food products of a type 
which is characteristic of a hot dog, of a uniform or non-uniform 
composition or of any such cross-sectional shape. Though the drawings 
generally illustrate an apparatus for a generally straight hot dog, it 
should expressly be understood that the preferred embodiment of the 
present invention may also be employed with a curved hot dog. 
Typically, the hot dog 12 is a ground or emulsified mix of meat, cereal, is 
formed into a generally elongate cylindrical shape with substantially 
hemispherical ends, and is pre-cooked prior to sale to the consumer. The 
hot dog 12 as received by the consumer may be approximately 0.625 inches 
(15.9 millimeters) in diameter and 5 inches (127 millimeters) in length, 
although many other dimensions are common. For example, hot dog-type 
sausage food products such as sausages, wursts, and the like usually have 
greater lengths and diameters. 
The apparatus 10 includes an elongate generally cylindrical housing 14 
having an axis 16, and a circumferential side wall 18, as shown in FIG. 1. 
The side wall 18 has radially inner and outer surfaces 20, 22 (FIGS. 2-5), 
and the housing also has first and second axial ends 24, 26 (FIGS. 1 and 
2). As particularly seen in FIGS. 2-5, the housing 14 defines a cutting 
chamber 28 sized for receiving the hot dog 12. The side wall 18 includes a 
plurality of elongate, generally parallel axial slots 30 that extend 
through the side wall 18. As will be explained in more detail below, at 
least some and preferably all of the slots 30 correspond to slits to be 
made in the exterior of the hot dog 12. 
In the preferred embodiment of the present invention, eight slots 30 are 
generally equally spaced from each other around the circumference of the 
side wall 18. However, one skilled in the art will recognize that a 
greater or lesser number of slots 30 may be provided in the side wall 18 
of the housing 14 and that the slots 30 may be unevenly spaced without 
departing from the spirit and scope of the present invention. For example, 
if the apparatus is sized for a larger diameter product such as a 
knockwurst, twelve or sixteen slots 30 may be provided. 
In the preferred embodiment of the present invention, the apparatus 10 also 
has a generally annular cutter member 32. As seen in FIG. 2, the cutter 
member 32 has an axial length L. As seen in FIGS. 3 and 4, the cutter 
member 32 has a generally annular body 34 with a curved inner 
circumferential surface 36. The cutter member 32 extends around and is 
generally coaxial with the housing 14. Accordingly, the inner surface 36 
has a diameter that is at least slightly greater than the diameter of the 
outer surface 22 of the housing side wall 18. 
The cutter member 32 includes a plurality of generally radially inwardly 
extending blades 38. As particularly seen in FIGS. 2 and 3, each blade 38 
is a generally planar member with a cutting edge 39, where the planar 
member resides in a plane generally parallel with respect to the axis 16 
and the cutting edge is generally diagonally oriented with respect to the 
axis 16 and facing toward the first end 24 of the housing 14. Preferably, 
the blades 38 are spaced generally evenly around the circumference of the 
cutter member 32, and each blade 38 is generally aligned with and extends 
through one of the slots 30 of the housing 14 and into the cutting chamber 
28. 
As shown in FIG. 2, the cutter member 32 may be axially moved with respect 
to the housing 14 from a first position to a second position. In the first 
position, the cutter member 32 (shown in solid in FIG. 2) is adjacent the 
second end 26 of the housing 14. In the second position, the cutter member 
32 (shown in phantom in FIG. 2) is adjacent the first end 24 of the 
housing 14. As should now be understood, when the hot dog 12 is positioned 
within the cutting chamber 28, the movement of the cutter member 32 from 
the first position to the second position causes each of the blades 38 to 
slit the hot dog 12. 
More particularly, by the axial movement of the cutter member 32, the 
blades 38 make a plurality of generally parallel axially extending cuts or 
slices through the exterior and into the hot dog 12 located within the 
cutting chamber 28. Preferably, in both the first and second positions of 
the cutter member 32, the blades 38 are not in contact with the hot dog 
12. Accordingly, the slits made by the blades 38 extend along 
substantially the entire axial length of the hot dog 12 from one end to 
the other. 
Preferably, and as seen in FIGS. 2 and 3, the cutter member 32 has one 
blade 38 for each slot 30 of the housing 14 such that one blade 38 resides 
within each slot 30. However, one skilled in the art will recognize that 
other numbers of blades 38 may be employed and/or the blades 38 may be 
unevenly spaced without departing from the spirit and scope of the present 
invention. 
Preferably, and as best seen in FIG. 2, the blades 38 on the cutter member 
32 are organized into first and second tiers 40a, 40b. As particularly 
seen in FIGS. 3 and 4, the first tier 40a preferably includes four spaced 
blades 38 at a first axial position with respect to the housing 14 and the 
second tier 40b includes four spaced blades 38 at a second axial position 
with respect to the housing 14. Preferably, and as best seen in FIG. 3, 
the blades of the first tier 40a are staggered with respect to the blades 
of the second tier 40b. As shown, the blades 38 of the first tier 40a are 
spaced about 90 degrees from each other, the blades 38 of the second tier 
40b are likewise spaced about 90 degrees from each other, and each blade 
38 in the first tier 40a is circumferentially offset about 45 degrees from 
a circumferentially adjacent blade 38 in the second tier 40b. 
As shown, when the cutter member 32 is moved from the first position toward 
the second position, the blades 38 of the first tier 40a contact the hot 
dog 12 first, while the blades 38 of the second tier 40b are delayed in 
contacting the hot dog 12 until the first tier 40a has already penetrated 
the exterior of the hot dog 12. As should be appreciated, such an 
arrangement is preferable in that the pressure necessary to initiate four 
cuts simultaneously in the exterior of the hot dog 12 is less than the 
pressure necessary to initiate eight such cuts simultaneously. As one 
skilled in the art will recognize, the preferred embodiment of the present 
invention may have a different number of tiers of blades 38 in the cutter 
member 32 and a different arrangement of the blades 38 without departing 
from the spirit and scope of the present invention. For example, if the 
cutter member 32 is to have twelve blades 38, the blades may be organized 
into three staggered tiers. 
Preferably, each blade 38 extends a predetermined distance into the cutting 
chamber 28, where such predetermined distance is less than the distance to 
the axis 16. Accordingly, the hot dog 12 is not severed within the cutting 
chamber 28 into discrete pieces when the cutter member 32 is moved from 
the first position to the second position, and at least a portion of the 
hot dog 12 proximate the axis 16 is not cut. As a result, the slitted hot 
dog 12 remains as a unitary body. Preferably, the un-cut portion of the 
hot dog 12 has a diameter of at least one-quarter of an inch, and acts as 
a core from which the cut portions of the hot dog 12 radiate. 
Preferably, and referring now to FIG. 2, the apparatus 10 includes a 
generally circular base member 42 that is removably secured to the first 
end 24 of the housing 14. As seen, the base member 42 may be inserted into 
the housing 14 by coaxially aligning the base member 42 at a first 
position (shown in phantom in FIG. 2), and then axially guiding the base 
member 42 into contact with the housing 14 (as shown in solid in FIG. 2). 
Preferably, the base member 42 maintains an interference fit with the 
housing 14 by way of an annular base flange 43. 
Preferably, and as seen in FIGS. 2 and 5, the base flange 43 is generally 
coaxial with the housing 14 and the base member 42, extends axially from 
the base member 42 toward the second end 26 of the housing 14, and is 
sized to encircle the outer surface 22 of the side wall 18. As shown, when 
the base member 42 is secured to the housing 14, the base flange 43 aids 
in limiting the movement of the cutter member 32 toward the first end 24 
of the housing 14, and helps to define the second position of the cutter 
member 32 as was described above. Preferably, the slots 30 extend along 
the side wall 18 of the housing 14 short of the farthest extreme of the 
first end 24 and are closed at such farthest extreme. Preferably, the 
closures at such farthest extreme contact a non-sharp, posterior portion 
of each blade 38 of the first tier 40a to limit the movement of the cutter 
member 32 toward the first end 24 of the housing 14 and to define the 
second position of the cutter member 32 along with the base flange 43. 
As seen, the base member 42 includes a pedestal or support member 44 that 
is generally coaxial with and extends into the cutting chamber 28. 
Accordingly, the hot dog 12 is inserted through an aperture in the first 
end 24 of the housing 14 and is positioned within the housing 14 by being 
coaxially aligned with the housing 14, the pedestal 44, and the base 
member 42 as the base member is inserted into the housing 14. Preferably, 
the pedestal supports the hot dog 12 in the cutting chamber 28 a 
predetermined distance from the first end 24 of the housing 14. As should 
be understood, the predetermined distance generally corresponds to the 
axial length L of the cutter member 32, such that the blades 38 in both 
the first and second tiers 40a, 40b of the cutter member 32 slice through 
the complete length of the hot dog 12. 
Preferably, and as best seen in FIGS. 2 and 5, the pedestal 44 includes a 
plurality of spaced, radially extending support fins 46 for supporting the 
hot dog 12 within the cutting chamber 28. Although eight fins 46 are 
shown, one skilled in the art will recognize that a different number of 
such fins 46 may be employed without departing from the spirit and scope 
of the present invention. For example, four evenly spaced fins 46 may be 
employed. Moreover, one skilled in the art will recognize that the fins 46 
need not be evenly spaced while still being within the spirit and scope of 
the present invention. 
However, and as is shown in FIG. 3, it is necessary that each fin 46 be 
positioned so as to prevent interference with the blades 38 in both the 
first and second tiers 40a, 40b. Preferably, and as shown, each blade 38 
in the first or second tier 40a, 40b is circumferentially spaced about 45 
degrees from a circumferentially adjacent blade 38, as was described 
above, and each fin 46 is circumferentially offset about 22.5 degrees from 
a circumferentially adjacent blade 38. 
Preferably, and as shown in FIG. 5, the base member 42 and the housing 14 
in combination include a reference device 47 to ensure that the fins 46 
are properly positioned with respect the blades 38 when the base member 42 
is secured to the housing 14. As seen, the reference device 47 is at the 
base flange 43 and at the outer surface 22 of the side wall 18 of the 
housing 14. As should be understood, the reference device 47 limits the 
fins 46 to a circumferential position that does not interfere with the 
blades 38. Preferably, the reference device 47 includes a notch in the 
base flange 43 and a matched key on the housing 14, although one skilled 
in the art will recognize that other types and arrangements of reference 
devices may be employed while still being within the spirit and scope of 
the present invention. 
Preferably, and referring now to FIGS. 1 and 2, the apparatus 10 includes 
an annular coaxially positioned cap member 48 secured to the second end 26 
of the housing 14. As seen, the cap member 48 has a radial outer dimension 
at least slightly greater than the diameter of the inner circumferential 
surface 36. Accordingly, the cap member 48 limits the movement of the 
cutter member 32 toward the second end 26 of the housing 14, and defines 
the first position of the cutter member 32 as was described above. 
Preferably, when the cap member 48 is not secured to the second end 26 of 
the housing 14, the slots 30 extend along the side wall 18 of the housing 
14 to the farthest extreme of the second end 26 and are open at such 
farthest extreme. Accordingly, in constructing the apparatus 10, the 
cutter member 32 is preferably slipped onto the housing 14 at the second 
end 26 and the blades 38 are positioned within the open slots 30 prior to 
the attachment of the cap member 48. The slots 30 are closed when the cap 
member 48 is secured to the second end 26 of the housing 14. 
Preferably, the cap member 48 is epoxied, sonic welded, fused, or otherwise 
permanently secured to the housing 14. However, one skilled in the art 
will recognize that the cap member 48 may be removably secured to the 
housing 14 if so desired without departing from the spirit and scope of 
the present invention. For example, the cap member 48 may be screwed or 
snapped onto the housing 14. 
Preferably, and as best seen in FIGS. 1 and 2, the cutter member 32 
includes a pair of gripping members 50 that extend generally radially 
outwardly with respect to the housing 14. As should be understood, the 
gripping members 50 facilitate the application of pressure by an 
individual to move the cutter member 32 with respect to the housing 14 
from the first position to the second position. Preferably, the apparatus 
10 is placed in an upright position with the base member 42 down and the 
cap member 48 up during such application of pressure. Although only two 
gripping members 50 are shown, one skilled in the art will recognize that 
a larger number of gripping members 50 may be employed and that the 
gripping member 50 may be replaced with a substantially coaxial gripping 
ring or the like without departing from the spirit and scope of the 
present invention. 
Preferably, the housing 14, the cutter member 32 including the blades 38, 
the base member 42 and support member 44, and the cap member 48 are 
constructed from a polymeric material. For example, the polymeric material 
may be polystyrene. However, one skilled in the art will recognize that 
other materials may be employed without departing from the spirit and 
scope of the present invention. For example, the blades 38 of the cutter 
member 32 may be steel blades. 
As should now be appreciated, with the apparatus 10 of the preferred 
embodiment of the present invention, the exterior of the hot dog 12 is 
provided with a plurality of generally parallel axially extending slits, 
and the slits prevent the hot dog from rupturing. Further, it has been 
found that by making the axial slits with a predetermined depth and then 
cooking the hot dog 12, a bitten-off piece of the cooked hot dog 12 will 
break down into smaller discrete pieces defined by the slits with little 
if any chewing required. As should be understood, then, the risk of 
choking on such smaller discrete pieces of the cooked hot dog 12 is less 
then the risk of choking on one larger piece. 
From the foregoing description, it can be seen that the present invention 
comprises a new and useful apparatus for cutting a hot dog and similar 
sausage food products. It will be appreciated by those skilled in the art 
that changes can be made to the embodiment described above without 
departing from the broad inventive concepts thereof. It is understood, 
therefore, that this invention is not limited to the particular embodiment 
disclosed but is intended to cover modifications within the spirit and 
scope of the present invention as defined by the appended claims.
