Stomper For Food Grinder

Abstract

A stomper for a food grinder comprises a distal end adapted to push food into a receiving tube of a food grinder, a proximal handle end adapted for a user to grasp the stomper while pushing food into the receiving tube of the food grinder, an elongated shaft between the distal end and the proximal handle end, a channel defined in the proximal handle end, and a bayonet projecting from one or more internal walls of the channel. The bayonet is adapted to engage a protrusion on an auger of the food grinder to apply a pulling force to remove the auger from the food grinder.

DETAILED DESCRIPTION OF THE DISCLOSURE

[0014] Certain terminology is used in the following description for convenience only and is not limiting. The words “lower,” “bottom,” “upper,” and “top” designate directions in the drawings to which reference is made. The words “inwardly,” “outwardly,” “upwardly” and “downwardly” refer to directions toward and away from, respectively, the geometric center of the device, and designated parts thereof, in accordance with the present disclosure. Unless specifically set forth herein, the terms “a,” “an” and “the” are not limited to one element, but instead should be read as meaning “at least one.” The terminology includes the words noted above, derivatives thereof and words of similar import.

[0015] Referring to the drawings in detail, wherein like numerals indicate like elements throughout, FIGS. 1-5 illustrate a food grinder system and stomper for a food grinder in accordance with a preferred embodiment of the present disclosure. A stomper, also called a pusher or a plunger, is used to push food into the food grinder while keeping a user's hands safely away from any moving parts that could potentially injure the user.

[0016] The food grinder system of embodiments of the present disclosure comprises a food grinder 10 and a stomper 50. The food grinder 10 comprises a base 12 housing a motor (not illustrated), a throat portion 18 coupled to the base, a receiving tube 16 coupled to the throat, and a feeding tray 14 (also termed a hopper tray) coupled to an upper end of the receiving tube 16. Food to be ground may be placed on the feeding tray 14 and directed toward a hole (not illustrated) that leads to the receiving tube 16. A stomper 50 may be used to push the food down into the receiving tube 16. A selectively rotatable auger 30 is inserted into the throat portion, such that a shaft 32 at the inner end of the auger engages with the motor. The auger has a spiraling main body 34 for propelling food and a protrusion 36 at the outer end. The protrusion 36 has a circumferential groove 38. A rotating blade (not illustrated) may be placed on the protrusion 36. A disk or plate 22 with a plurality of holes (different disks are typically available with different sizes holes) is placed on the protrusion 36. A locking nut 20 is screwed or otherwise affixed onto the end of the throat portion 18 to secure the disk 22, the blade (if equipped), and the auger 30 in place.

[0017] It is also known that the auger may be connected to accessory auger for sausage making. See, for example, U.S. Pat. No. 7,144,316. The auger still serves the role of propelling a meat product from a receiving tube through a throat portion.

[0018] To operate the food grinder 10, the motor is powered on, which rotates the auger and the blade (if equipped), and food is pushed down into the receiving tube 16 until the food reaches the auger 30. The rotating auger propels the food toward the grinder outlet. If a blade is equipped, it grinds the meat and the finished product is propelled out through the disk 22. For sausage making, the meat is pushed into a tube. Additional or alternative accessories for the grinder appliance may be employed. However, the auger is the motive force for the food through the grinder appliance.

[0019] After the food processing is complete, the food grinder 10 needs to be disassembled for cleaning, as would be understood by one familiar with the art. As part of the disassembly, the auger 30 is pulled out of the throat portion 18. A user may attempt to remove the auger by pulling on the protrusion 36. However, as discussed above, the protrusion will likely be greasy. Further, any residual meat product may make pulling the auger difficult. It can be difficult to remove the auger by hand.

[0020] A stomper 50 for use with a food grinder of embodiments of the present disclosure is illustrated in FIGS. 3 and 4. The stomper 50 comprises an elongated shaft 56 with a distal end 58 sized and shaped to push food into the receiving tube and a proximal handle end 52 for a user to grasp and hold the stomper 50. The distal end 58 may be flared as illustrated. The stomper 50 may have a guard 54 to limit how far the stomper can be inserted into the receiving tube 16 and to help ensure that the user's hand is kept away from the receiving tube 16.

[0021] In addition to functioning as a conventional stomper, the stomper 50 of embodiments of the present disclosure functions as a tool for pulling the auger out of the throat portion. A channel 60 is defined in the end and side surfaces of the proximal handle end of the stomper 50. A bayonet 62 projects from the internal walls of the channel 60. “Bayonet” here indicates a reduced diameter subsection of channel 60. As illustrated, one embodiment of the bayonet 62 has a curved engaging surface to correspond with the circular surface of the auger protrusion 36 and groove 38. The bayonet 62 is able to engage the groove 38 on the protrusion 36 of the auger 30. As best illustrated in FIG. 5, and further described below, the distal end of protrusion 36 cannot fit through the bayonet 62 subsection of channel 60. Once groove 38 is positioned within bayonet 62, pulling stomper 50 away from auger 30 along the axis of the auger 30 withdraws or pulls auger 30 from throat portion 18.

[0022] In further detail, the stomper 50 is positioned such that the auger protrusion 36 is at least partially within the stomper channel 60 and the bayonet 62 engages the groove 38. Once engaged, the user can apply a pulling force to remove the auger from the food grinder. In other words, the bayonet is operable to transmit a pulling force on the stomper to the auger in order to remove the auger from the grinder. FIG. 5 illustrates the stomper 50 in position relative to the auger and one embodiment of the bayonet engaged with the groove (the stomper is shown in cross-section).

[0023] While the groove of the auger protrusion is illustrated having a curved (i.e., concave) shape, any suitable shape may be used. For example, the groove could have a squared shape or an angled (e.g., V-groove) shape. Having a differently shaped groove may or may not necessitate a change to the engaging surface of the bayonet.

[0024] Stomper 50 is used to push the meat product into the throat portion of the grinder. As such, it is already exposed to raw meat during use of the grinder and must be cleaned by the user. The presently disclosed improvement to grinders eliminates the need for a separate tool that can be lost and must also be cleaned after contacting the auger. Further, the present disclosure provides a simpler and less expensive solution relative to using an additional single-purpose tool. Overall, the lower costs and reduced parts improve the user experience.

[0025] It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this disclosure is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present disclosure as defined by the appended claims.
