Definitions

  • This invention relates to power operated slicing knives, and particularly to a knife adapted for slicing meat and other foods or materials by blades disposed in either vertical or horizontal cutting positions while the user holds the knife in a predetermined position without rotating the body of the knife as a whole about its longitudinal axis in order to change the cutting position of the blades.
  • Power operated knives on the market commonly are provided with elongated generally cylindrical housings shaped to be gripped in the hand of a user in a predetermined position wherein the blade are disposed in vertical planes and are adapted for slicing by cutting in vertical planes. If the user of such a knife desires to slice in a horizontal plane, it is necessary to turn or rotate the knife bodily about its longitudinal axis in order to place the blades at the desired angle. This rotation of the knife body from its initially designed position deprives the user of the benefit of the shape or configuration of the knife body which was originally provided to aid the user in grasping and holding the knife with the blades in vertical planes.
  • the main object of my invention is to provide means for rotating the knife blades 90 degrees from their normal vertical planes without turning the body of the knife as a whole, thereby permitting the user to perform the slicing in either vertical or horizontal planes while holding the knife by its handle or by gripping the body of the knife in the manner intended for vertical slicing.
  • Another object of the invention is to provide means for preventing release or removal of the blades except when the blades are in the vertical position relatively to their housing and parallel to the release means.
  • Another object of the invention is to provide a turret mounted on the forward end of the knife, rotatable about the longitudinal axis of the knife housing, for quick manual adjustment of the blade positions in either vertical or horizontal positions.
  • FIG. 1 is an elevational side view of one form of power operated knife embodying my invention.

  • FIG. 4 is a top plan view of the lower housing member and the parts mounted therein, the upper housing and handle being omitted for clarity.
  • FIG. 5 is a transverse vertical sectional view in the plane of the line 55 of FIG. 4, showing blade carriers and the blades in vertical cutting positions.
  • FIG. 6 is a view similar to FIG. 5, showing the same parts when the blades are in horizontal cutting positions.
  • FIG. 7 is a transverse vertical sectional view in the plane of the line 7--7 of FIG. 4, showing the carriers and the blades in their vertical cutting positions.
  • FIG. 8 is a view similar to FIG. 7 showing the same parts when the blades are in horizontal cutting positions.
  • FIG. 9 is an elevational side view of one of the blade retaining levers and carrier.
  • FIG. 10 is a sectional view in the plane of the line 10-10 of FIG. 9.

  • the blades 14 are provided with grease guards 21 each attached to the outer side of a blade adjacent the tangs 19, said guards 21 partially entering the turret 17 as shown in FIG. 4.
  • the motor 22 as a whole has a shaft 23.
  • a worm 24 on the end of the shaft 23 engages a worm gear 25 fixed on shaft 26.
  • a pair of cams 27 are eccentrically fixed on the shaft 26 to rotate with the shaft, their working faces being 180 apart.
  • the shaft is journaled in bearings 28 mounted in the gear housing 29.
  • the cams 27 are located between the flanged downturned arms 30 which are integral parts of the driver bars 31 and transmit reciprocatory motion to the blade carriers to be described hereinafter.
  • the driver bars 31 are generally flat and vertically disposed in their rearward portions which engage the cams 27.
  • the forward portion 32 of each driver bar is semicylindrical in transverse vertical section as shown in FIGS. 7 and 8.
  • One of the driver bars 32 is provided with a slot 33 and the other with a slot 34 between its ends.
  • the driver bar members 31 and 32 are connected together as indicated at 35.
  • the slot 33 extends arcuately more than degrees in the left hand driver member 32 from above a horizontal plane to the right of a vertical plane, and the slot 34 extends more than 90 degrees in the right hand driver 32 from left of the vertical plane to below a horizontal plane.
  • Reinforcing ribs 36 are located in the driver members 32 at opposite sides of the slots 33, 34.
  • Two blade carriers 41 are generally semi-cylindrical on their outer surfaces, in transverse vertical section, and are located between the driver bar members 32for rotative movement relatively to said bars.
  • Each of the carriers 40 is provided with a centrally bored boss 41 which projects laterally from the carrier body 40.
  • One boss 41 extends through the slot 33 of a driver bar 32 and the other boss 41 extends through the slot 34 of the other driver bar 32.
  • Each carrier 40 is retained rotatably relatively to a driver bar by a retainer ring 42 mounted on the outwardly projecting portion of the boss 41, said retainer ring 42 being held in place by a spring 43 mounted in a groove 44 near the outer end of the boss 41.
  • a retainer stud 45 in the central bore of each boss 41 has a head 46 on its inner end.
  • the stud 45 has pivotally mounted thereon a blade retainer 47in the form of a fiat lever, best shown in FIGS. 3 and 10.
  • The'lever is retained by the head 46 between the head and the inner surface of the carrier 40.
  • the retainer lever 47 has a hook 48 formed on its free end to provide a curved edge 49 which engages the projection 20 on a blade tang 19.
  • a retainer spring 51 has one end 52 hooked through an aperture in the lever 47 and its other end attached to a part of the carrier 40, as shown in FIGS. 9 and 10*, to normally hold the lever 47 in position wherein the hook -48 and edge 49 engage the projection 20 on the tang 19 of a blade 14.
  • the blade release button 16 shown in FIGS. 3, and 6, is mounted in the bottom wall of the lower housing 11 in position to contact the arms 50' of the levers 47 of the two carriers 40 .when the carriers are in the vertical positions shown in 'FIG. 5. When the blades are in the I horizontal position of FIGS. 6, the button 16 cannot contact the arms 50 of lever 47.
