Abstract
ABSTRACT OF THE DISCLOSURE
A circular cover has a peripheral flange to overhang and enclose the cutting edge of a rotating disk slicer knife in a slicing machine for meat and other foods. A central handle remote from the cutting edge of the knife disc is provided for applying the cover to the knife disk. Magnets recessed in handle protuberances at the rim of the cover secure the secure the cover to the knife disk, these handles being used to pull the magnets free of the knife disk in removing the cover.

Description
113~55'~ -r~his invention relates to a temporary safety cover to be applied ~o the rotating disk slicer knife when the operating guard is removed for cleaning the slicing machine.
Slicing machines used in a res~aurant for slicing servings of cooked meat and the like have a motor driven rotating disk slicer knife which is normally shielded by a conventional form of guard when the slicing machine is in operation. However, ~hen -the machine is to be~leaned or serviced from time to time the normal operating guard must be removed. The exposed sharpened edge of the knife disk then presents a serious hazard to the hands and fingers of a person cleaning or servicing the machine.
The present knife cover is equipped with securing means such as magnets t~ secure it to ~he flat surface of the knife disk when the normal operating guard has been removed. ~ circular flange on the cover overhangs and encloses the cutting edge of the disk so that the operator's hands cannot come into contact with the cutting edge while pieces of food are being wiped from portions of the slicing machine under and behind -the knife disk. There are pre-ferably a pair of magnets on the underside of the cover to secure the cover a~ two points on the knife disk and handles are provided on ~he upper side of the cover overlyin~ said magnets for pulling the magnets free of the disk to remove the cover. A
central handle remote fr~m ~he peripheral portion of the cover which approaches the cutting edge of the knife disk is provided for applying t~e cover to the knife disk.
Thus the invention is described as a safety cover for a rotating disk slicer knife comprising a circular member having a rim portion arranged to overlie the rim of said knife, a flange on said rim portion arranged to overhang and enclose the cutting edge of sa~d knife,securing means inside said cover co engage said knife and secure the cover to the`knife, and handle means comprising a protuberance on the outs~e of the cover overlying said securing means for removing the cover.
Various changes may be made in the details of construction and 10 ~rangement of parts and certain features may be used without others.
All such modifications withint the scope of the appended claims are included in the invention.
In the accompanying dra~ings, Fig. 1 is a perspec~ive view of a com~on form of slicing machine with the food carriage and normal opera-cing guard removed to illustrate the exposed position of the slicer knife disk when the machine is to be cleaned or serviced.
Fig. 2 is a ~op plan view of one embodiment of safety cover accordlng to the invention.
Fig. 3 is a sec-tional view on the line 3-3 in Fig. 2.
Fig. 4 is a -top plan view of a modifica-~ion.
Fig. 5 is a sectivnal view on the line 5-5 in Fig. 4.
In the slicing machine in Fig. 1 a motor 10 rotates a slicer knife disk 11 having a sharp edge 12 to slice servings from a large piece of meat such as a roas~ or a ham. In ~he use of the machine a sliding carriage (not shown) moves che Fiece of food back and forth across the rotating knife 11 and during ~his operation the knife 11 is shielded around mos~ of i periphery by a conventional form of guard.
Irhe operacing guard is removed in Fig. 1 to illuscrate the exposed condi-tion of -the sharpened edge 12 when -~he machine is il3155;~
prepared for cleaning from time ~o time during the day, or for servicing. The operator must bring his hand close to the sharp edge 12 in wiping away pieces of meat that have fallen below and behind the knife disk 11, this being a dangerous operation, especially when performed in haste as is often necessary in a busy restaurant.
rhe first embodiment of cover 13 shown in Figs. 2 and 3 has a narrow rim portion 15 with a perpendicular circular flange 15 to overhang and enclose the cutting edge 12 of the knife. An integral diametrical portion 17 of the cover provides a convenient central handle for applying ~he cover tO the knife 11 as shown in Fig. 1 while leaving the cover open at 18 on opposite sides of handle 17 for economy of construc~ion and reduc~on of weight.
At each end of handle portion 17 a magnet 20 is mounted in a recess 21 in a handle protuberance 22 by a screw 23. Thus the magnets 20 engage the steel knife disk 11 and secure the cover 13 to the knife disk. The cover is readily removable from knife disk 11 by grasping a handle 22 in each hand and pulling the -two magnets 20 away from the knife disk 11. Since the handles 22 are directly connected to the magnets 20 no stress is applied to other parts of the cover in pulling the magnets away from the knife disk and the cover may ba made of rela-tively thin plastic ma~erial.
The modification 24 in Figs. 4 and 5 contains the same magnet 20 and handle 22 arrangement just described but has a continuous plastic cover 25 without the openings 18. In this modification there is an attached knob handle 26 in the center of the cover for applying the cover to the knife disk 11. The head of handle screw 27 in Fig~ 5 is received in the central recess 28 in knife disk 11 whereby the protruding screw head does no~- tend to hold mag-nets 20 away from contact wi~h the knife disk~
A single central handle and magnet may be used without the rim magnets and handles 22 but the arrangements described above are preferred. Two magnets in opposite sides of the cover insure that the entire circumference of the cutting edge 12 is adequately covered.
