The blade is retained by a partial peripheral flange 90 of the housing and a pivoted retaining shoe 36 secured to the knife hand piece 22. A securing screw 40 and an adjustable abutment 80 retain and position the shoe against the blade. The arrangement allows convenient blade changing. A handpiece 22 has asymmetrically flared recesses 56, 130, 132 adjacent the blade for promoting discharge of product particles that tend to accumulate. The shoe and housing substantially cover gear teeth 42 of the blade.

Rotary hand knife

An improved product pusher for a cutting apparatus. The pusher slides downward along an upright receptacle to urge a comestible product, such as meat through a magazine movable past a cutter of the apparatus. The pusher has a catch for automatically retaining it at an upper end of the receptacle to facilitate loading the magazine. It also has two bottom surface portions with product engaging projections. In one arrangement the two surface portions are in a fixed angular relationship and a spring-biased stripper plate is beneath one of the surface portions, extending in a common plane with the other surface portion. In another arrangement the two surface portions are relatively pivoted and securable in either an angular relationship or co-planar.

The magazine has product receptacles 76, 77 constructed for convenient removal from a one-piece molded plastic supporting base 40, all of which facilitates cleaning the machine. The base 40 is received on the end of a drive shaft 30 and is adjustable in height relative to the shaft. A plate 71 secured to the shaft and clamped against the base secures the receptacles and eliminates wobble from clearance between the base and shaft. Projections 122, 123 from the plate 71 transmit rotary force between the drive shaft and base. Pusher plate assemblies 94, 96 slide along the receptacles to urge products through the magazine 26.

Slicing apparatus having rotary magazine

An apparatus for tenderizing a comestible product, such as meat, comprising an intermittently advanced horizontal conveyor for conveying a product to be processed underneath a set of knives in a knife carriage supported for vertical reciprocation toward and away from the conveyor. The knife carriage has a plurality horizontal plate-like members fixed in vertical spaced relative to one another and discrete knife assemblies each comprising a rod-like member slidable in closely spaced vertically aligned apertures of upper plate-like members and extending to opposite sides thereof. The rod-like members each have a flange at the upper side of an intermediate plate-like member normally engaging the same. A discrete compression spring surrounding each of the rod-like members is interposed between the flange thereon and the under side of an upper plate-like member which is adjustable towards and from the intermediate plate-like member. A plurality of tenderizing blades or knives are connected to the lower ends of each rod-like member and extend through individual apertures in a lower plate-like member. A product stripper plate is arranged to move downwardly and upwardly in timed relation with like movements of the knife carriage and to rest upon the upper surface of the product during piercing thereof by the tenderizing knives and to be locked in said position while the knives are withdrawn from the product. The knife carriage is movable to a horizontal position for ready accessability to the knife assemblies etc. for servicing, such as, replacement etc.

Tenderizer

A hand knife for use in processing meat. The knife has a handle, a circular housing secured to one end of the handle, and a rotatably power driven ring-like blade in part circumferentially contained by the housing. An arcuate wear pad or plate overlies a portion of the inside surface of the blade adjacent the handle limiting movement of the blade away from the blade housing near the handle and against the surrounding housing opposite the handle during use, distributing wear that otherwise occurs between the interior of the surrounding housing and the outside of the blade, and transferring some of the wear to the exterior of the wear plate and the inside of the blade. The ends of the wear plate are tapered outwardly and toward the blade and each has a surface transverse to and overlying the inside surface of the blade. The transverse surfaces form knife edges at the inside surface of the blade and deflects outwardly cut portions of product being processed as they move through the blade and housing and limit their movement circumferentially with the blade.

Ring blade knife having wear plate

An apparatus for tenderizing a comestible product, such as meat, comprising an intermittently advanced conveyor for conveying a product to be processed underneath a set of thin knives supported for vertical reciprocation toward and away from the conveyor by a knife carrier or carriage having three horizontal plate-like members fixed in vertical spaced relation to one another having a multiplicity of closely spaced vertically aligned apertures and discrete blade or knife assemblies each comprising a rod member slidable in each of the aligned apertures of the upper plate-like members and extending to opposite sides thereof. The rod members each having a flange at the upper side of the intermediate plate-like member normally engaging the same. A discrete compression spring surrounding each of the rod members and interposed between the flange thereon and the under side of the upper plate-like member which is adjustable towards and from the intermediate plate-like member. A further horizontal plate-like member below the lower plate-like member supported by the knife carrier for limited movement towards and from the knife carrier and having apertures therein through each of which an individual knife extends. A product stripper plate arranged to move downwardly and upwardly in coordination with like movements of the knife carrier and to rest upon the upper surface of the product being pierced and to be locked in said position while the knives are withdrawn from the product. The aforementioned further horizontal plate reduces the length of knife shank which would otherwise be unsupported against bending during operation on a product.

A hand knife having a ring-like rotary blade the diameter of which is considerably greater than its axial length rotated by a motor in a handle extending normal to the axis of rotation of the blade. The blade of the knife is rotatably supported in a blade housing that surrounds it and which can be removed together with the blade for sharpening of the blade by merely loosening a pair of threaded fasteners. The knife also has a member in the interior of the blade which guides a part being removed from a product being processed through the central opening of the blade and interferes or restricts the movement of the part with the circular rotation of the blade thereby increasing the efficiency of the cutting operation. The material guiding and restricting member is connected to the knife by the same fasteners which connect the knife housing to the knife handle, may be angularly adjusted within the blade and/or may also be disassembled from the knife without removing the fasteners.
