7 Claims. (01. 146-402) This invention relates to slicing machines and is particularly directed to slicing machines in which the article to be sliced is manually fed I to a motor driven cutting knife.
In general, the object of this invention is to improve the various parts of a slicing machine.
More specifically, an object of the invention is to provide a slicing machine in which the articleholding feeding carriage may be moved past -a knife without encountering any obstructions from the knife guard which would limit the stroke of the carriage.
Another object of the invention is to provide means for supporting and housing a grinding device so as to provide a rear wall for the grinding device lying in the same plane as the knife edge and serving as an article abutment and as a guard for the rear knife edge.
Still another object is to provide an improved -means for receiving the scrap which falls from the knife during a cutting operation.
Another object is also to provide novel means for supporting the gauge plate housing from the knife supporting frame.
Another object is still further to provide means for guarding the knife which may be easily placed Without removing it from the machine in inoperative position to permitaccess to the knife for cleaning or other purposes.
Still further another object of the invention is to provide a novel scraping construction for cleaning the knife.
Various other. objects and advantages of my invention will be obvious from the following particular description of one form of mechanism embodying the invention or from an inspection of the accompanying drawings; and the invention also constitutes certain new and novel features 'of construction and combination of parts hereinafter set forth and claimed. i
In the drawings:
Fig. 1 is a side view of the feeding side of the slicer.
Fig. 2 is a side view, of the motor side of the slicer.
Fig. 3 is a top .view of the slicer.
Fig. 4 is a section onrline 44, of Fig. 1.
Fig. 5 is a detail view showing the position of the grinder device during the knife sharpening operation.
Fig. 6 is a rear view of the grinder, and
Figs. 7 and 8 are sections on lines 7-7 and 8-8- respectively of Fig. 1.
Referring to the drawings in detail, the slicing machine comprises a base 10 on which is mounted a motor 11 connected by a belt 12 to the pulley 13 which carries knife 14. The pulley is provided with a shaft 15 journalled in the hub 16 on the pedestal 17 which is integral with the frame 18 having radial arms 19 and 20 on the motor side of the knife. The bushing 21 lining the hub on which the shaft of the pulley is mounted has a depression therein in which is set a screw 23 threaded through the hub 16 (see Fig. 4). After assembling the knife and pulley in the hub the set screw 23 is tightened, thus preventing adjustment of the knife and knife pulley relative to the frame 18.
On the feed side of the knife the base carries a round rail 25 supported by posts 26 and a flat r rail 2''? vertically underneath the round rail. The article holding carriage 28 is slidably mounted on these rails for movement to and from the knife. The carriage may be provided with any suitable clamping means for clamping an article to the carriage.
The radial arm 19 of the frame 18 is provided at its outer end with a horizontal extension 30, the vertical face of which is in flush abutment with a vertical surface of the gauge plate housing 31, a screw binding together the extension and housing, which is further supported by an angular piece 32 carried at one end by the right hand post (as viewed in Fig. 2) and at the other end bolted to the bottom of the gauge plate housing. The gauge plate 33 (Fig. 1) may be adjusted by any well-known means to adjust the thickness of slice to be cut. The op erating means for the gauge plate adjusting device comprises a handle 34 and an index plate 35 movable therewith and cooperating with a pointer-36 to indicate the gauge plate adjustment. A cover 37 for the gauge plate housing is fast thereto.
In previous machines of this type it has been known to use a cover plate for the feed side of the knife which in order to guard the rear edge of the knife has been deflected outwardly from the plane of the knife. Consequently, the article on the feed carriage could not move past the deflected portion of a cover plate without being forced away from the knife plane. The feeding stroke of the machine and the length of slice to be cut was thereby limited.
In the present construction the feeding carriage is free to move past the rear edge of the knife since the cover plate 40 is not offset from the plane of the rear edge of the knife but sets entirely within the recess 41 of the knife. The
rear end of the knife is thus left uncovered. As the article moves past the rear edge of the knife it is necessary that a backing means be provided therefor to prevent its movement relative to the plane of the knife. Such movement would result in the tearing of the article by the knife and in a slice of varying thickness. The backing means in the present case consists of a lower flat plate substantially in the same plane as the rear knife edge and an upper flat plate 46 also in the same plane with the rear knife edge. In addition to serving as abutments-for the meat or other article after it passes the rear edge of the knife, these plates serve to guard the rear knife edge so thatv the operator cannot accidentally engage his fingers with said knife edge. The upper plate 46 further serves as a rear wall of the housing 50 for the knife grinding device while the lower plate 45 further serves as a cover for the drive means of the knife.
The grinder device is substantially of the same structure as shown in Patent 1,753,635. In brief, it comprises a grindstone 51 having 'a threaded stem 52 carried by the front wall of the housing 50 and provided with a knob 53 for adjusting it. A burringstone 54 is also provided witha threaded shaft 55 carried by the front wall of the housing 50 and provided with a manipulating knob 56.
The housing 56 has an integral sleeve 57 rotatably and slidably mounted on a stud 58 carried by the cars 59 of a U-shaped bracket 69 fastened to the inclined. face of the rear portion 61 of the knife carrying frame. lhe ears 59 each carry a plunger 62 adapted to seat in a corresponding notch 63 of sleeve 57 of the grinder housing. 'In operationthe grinder device is moved from an inoperative position in which the rear plate 46 guards the knife edge to an operative position in which the grinder 51 and the burring stone 54 may be moved into engagement with the knife edge, by first rotating the grinder device about the stud 58 away from the knife then moving the device along the stud 58 towards the plane of the knife and subsequently moving it towards the knife.
In grinding position, the left hand plunger 62 as seen in Fig. 6 engages in the corresponding recess 63 of the portion 57 and prevents rotation of the grinder device. In the non-grinding position the right hand stud engages the corresponding recess 63 to prevent rotation of the grinding device. In order to change from one position to another, it is necessary to retract the plunger engaging the recess 63.
A scraper is provided which consists of a spring metal strip 65 having a fibre block 66 at the end for engaging the knife. The strip 65 is fastened to a stud 6'7 rotatable on a pin'68.
. In order to prevent excess springiness of the I secured to the main frame 18. A pan '74 is provided beneath the scrapperto catch the scraps falling from the knife. The scrap pan has a front plate and a rearwardly extending curved bottom 76, the upper end of which catches under a spring latch 77. The plate'75 has at its lower end an inset lug 78 which catches on a proiection 79 on the frame 18 to prevent the movement of the scrap pan upwardly when the pan is in position.
The latch 77 prevents accidental movement of the scrap pan outwardly. Fastening means for the cover plate 40 comprises an upper set of pins 80, the heads 81 of which engage the cover plate when turned downwardly and'which when alined with the slots 82 of the upper cars 83 permit the cover plate to slip off the pins 80. Springs 84 located in recesses 85 of the radial arms 19 and 20 tend to hold the heads of the pins 80 in engagement with the cover ,plam. The lower end of the cover plate is held to the frame by pins 86 engaging in slots 87 of the lower deflected portion 88 of the cover plate. Pins 86 are urged by springs 89 in a direction to normally engage the cover plate.
The lower abutment plate 45 is removably fastened to the frame by latching elements 90 threaded into the frame 18 and which when moved into alignment with slots 91 in theplate permit removal of saidplate from the machine. The radial arm 20 carries at its upper end a hinge 92 on which is swin'gable the tubular guard 93 which guards the upper knife edge. The free end of the guard 93 is provided with a slot 94 which permits the guard 93 to be swung on the hinge 92 away from theknife when the latch 95 threaded in the arm 19 is, in alignment with the slot. Guard 93 can thereby be moved into a position in which the portion of the knife guarded thereby may be accessible for cleaning- A deflector plate 96 has a bearing sleeve 97 fixed to the rear side thereof which is pro vided with'an opening for. receiving the stud 98 fixed to the motor side of the knife frame 18. A'set screw 991s carried by the bearing lug for engagement with'the stud 98 to fiX the deflector in position. A projection 100 on the frame adjacent the back of the deflector plate engages the deflector to wedgingly cam the lower end thereof into engagement with the front of the upstanding fiange 101' of the receiving tray 102. firmly in place.
'Whlle there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is the intention therefore to be limited only as indicated by the scope of the following claims. I V
