In the embodiment of my invention illustrated in the accompanying drawings the frame I is of 1934, Serial No. 713,678
(Cl. 14S-153) a character and of such dimensions as to properly support the various parts of the machine but the details of the frame will be referred to only insofar as they directly relate-'to particular elements to be described.
The slicing mechanism comprises a slicing table 2 having a series of parallel slots 3 receiving the blades 4 mounted to reciprocate in these slots. The table 2 is detachably and adjustably mounted on the brackets 5 disposed in opposed relation on the side members of the frame and rabbeted to receivethe ends of the table grips 6 secured by the nuts I a l.ustably holding the table in position,. 1qvi -tli Ythe `fingers resulting from the slots which are open at the inner edge of the table between the blades. The forward ends of the fingers are preferably beveled as shown in Fig. 4. The table has a series of clearance or discharge holes 8 therein for the discharge of crumbs or debris resulting from the slicing.
Side plates or end guides 9 are adjustably mounted on the delivery table, these end guides having supporting brackets I0 adjustably secured by means of the clamping screws II in the slots I2. These end guides have longitudinal ribs I3 on their inner sides and the forward ends of the guides extend between the cutters as shown in Fig. 3. These ribs serve to hold the end slices and through them, owing to the slight compression, the entire sliced loaf in assembled relation as it is delivered across the table to the wraping machine conveyor.
I provide two cutter or knife units, each consisting of a frame I4 preferably formed as an integral aluminum casting and including upper and lower knife supporting bars I5 and I6, respectively, these bars having horizontal perforated ribs receiving the knife or blade coupling members I1 and I8. The upper coupling members are preferably provided with tensioning springs I9. The connections for the blades to the coupling members are conventionally shown in Fig. 6.
The cutter frames are provided with slides 2li of V cross section which coact with correspondingly shaped vertical ways 2| on the frame. The slides 20 have inwardly projecting journals 22 which engage the bearings 23 provided therefor in the frames, see Fig. 6. The cutter units are reciprocated so that one moves upwardly while the other moves downwardly, thereby minimizing i.,
the tendency of the cutters to displace the articles acted upon by the cutters.
The driving means in the embodiment illustrated comprises a crank shaft 24 having opposed cranks for the connecting rods 25. These connecting rods are connected to the crossheads 26 reciprocating in the cylinderlike vertical guides 21, pitman rods 28 being connected to these crossheads and having reduced portions 29 arranged through bores in the boss 39 on the lower cross piece of the cutter frames and detachably secured thereto by means of the nuts 3|. The slideways 2| are open at the top of the frame so that by releasing the pitman rod and removing the table 2 the cutter units may be removed as such from the machine. This is of particular advantage in that it allows the substitution of other cutter units so that the machine may be kept in substantially continuous operation while the knives are being sharpened, or permits substitution of other cutter frames with different spacing of knives for producing slices of different thickness. This, however, is usually quite standardized. Such a substitution of knives of different spacing would require the substitution of a table correspondingly spaced.
'I'he casing 32 for the crank shaft and crosshead guides is preferably adapted as an oil reservoir so that the parts may be kept efficiently lubricated. Packings 33 are provided for the rods 28, it being desirable to exclude lubricant as much as possible from the exposed parts of the machine.
While the articles to be sliced are acted upon by the knives they are held downwardly by means of finger-like holders 34 carried by the arms 35 having limited pivotal movement on the rod 36 disposed transversely across the machine. 'I'his rod is provided with pins 31 engaging the slots 38 in the arms, the slots being of such length as to limit the movement of the arms and consequently the swing of the holder members. The holder members project between the cutters, extending well beyond the rear cutters, so that the slices are urged thereby downwardly upon the table until the loaf is completely discharged from the cutter.
The supporting rod 36 is carried by brackets 36' on the frame and has anarm 39 carrying the adjusting nut 39' which coacts with a stop 40. This stop has threaded engagement with the arm so that the position of the holders may be accurately adjusted. The bracket is'split at 4 I, a clamping screw 42 being provided for clamping the rod in its adjusted positions.
The slicer feed conveyor is designed to feed the articles to the knife in a continuous stream and the articles are carried through the knives by the thrust of succeeding articles. This feed means comprises a bottom conveyor including a pair of conveyor chains 43 carried by the sprockets 44 on the shafts 45 and 46. These conveyor chains carry slats 41 preferably provided with longitudinal ribs 48. These slats are quite close together so that each article conveyed is engaged and supported by a plurality of slats. 'I'he ribs are provided to insure more effective engagement.
The shaft 46 is positioned so that the articles are delivered from this bottom conveyor to the slicing table, the relation of these parts being clearly shown in Fig. 4. 'I'he conveyor side bars or guides 49 are carried by the standards or brackets 50 adjustably supported by the adjusting screws 5| and 52. 'I'he brackets are simultaneously adjusted to and from each other. 'Ihe screw 5| is provided with a hand Wheel 53 and is connected to the screw 52 by means of suitable chain and coacting sprockets designated generally by the numeral 64.
The upper reaches of the conveyor chains 43 are supported by means of bars 55, see Fig. 2. The conveyor chains slide along on these bars which prevent the sagging thereof and hold the conveyor slats in alined position while carrying the articles." Y'Io further position the articles fed to the cutters, that is, so that the article is properly presented to the knives, the entire guide bar unit consisting of the guide bars and supporting screws may be adjusted laterally of themachine through the adjusting screw 56 which carries the yoke 51 engaging the ends of the screws 5| and 52 which are mounted in their bearings for limited sliding longitudinal adjustment.
The slicing machine feed mechanism also comprises a top conveyor acting to engage the tops of the loaves, holding them upon a bottom conveyor and also slightly compressing them to eliminate holes the presence of which is likely to result in distorted and broken slices. pressing action is conventionally illustrated in Fig. 7.
This top conveyor comprises supporting chains 58 with slats 59 extending between the same and carried thereby.
The sprocket Wheels 6| are carried by the tiltably mounted frames 61 which are pivoted on the drive shaft 61' of the sprockets 6| and adjustably supported by the screws 68. This enables the raising and lowering of the front end of the top conveyor. The frame 61 is longitudinally slotted at 69 to receive the shaft 18 of the pulleys 60 so that the sprocket chains may be adjusted by means of the screws 1|, the sprockets being rotatable on this shaft. The supporting bars 12 carried by the frames 61 serve to support the bottom reaches of theconveyor chains 58 when in loaf engaging position. The brackets 36 carrying the pivot rod 36 for the holders 34 are adjustably mounted on these upper conveyor supports 61, set screws 13 being provided for securing them in adjusted positions.
'I'he screws 65 are connected to be simultaneously rotated by means of the hand wheel 15 which is mounted on the shaft 16, this shaft being connected by the sprocket chain 11 and suitable sprockets to a shaft 18 disposed transversely of the frame and having beveled gears 19 thereon meshing with the beveled gears on the lower ends of the screws 65.
The driving shaft 61 for the sprockets 6| is provided with beveled gears 8| meshing with the beveled gears 82 splined to the vertical shafts 83, these shafts having beveled gears 84 on their lower ends meshing with coacting gears 35 on the shaft 46. This shaft 46 is connected to the driven shaft 86 by means of a variable speed transmission designated generally by the numeral 81. The gear box and the adjusting member 88 are the only parts of this transmission illustrated.
The shaft 86 is preferably driven from the wrapping machine, fragments of the intake conveyor of which are shown in operative relation to the slicing mechanism, see Figs. l, 3 and 4. A portion of the delivery mechanism of the wrapping machine is indicated at Fig. 1. The sprocket The comchain 89'connects thedlscharge conveyor of the wrapping machine, designated generally by the numeral 90, to the shaft 86 through a sleeve |23 and a clutch designated generally by the numeral |24.
The intake conveyor of the wrapping machine comprises the slideway 9| and the endless conveyor 92 having flights 93 cooperating with this slideway. The articles to be wrapped are discharged from the slicing delivery table 2 upon the receiving table 94 from which they are pushed on to the way 9| between the side members 95 and picked up and carried along by the flights. The wrapper feed control trip 9B is positioned to be engaged by the articles carried along by the flights. The conveyor side members 95 extend into cooperating relation with the guide members 9 of the delivery table.
The articles to be sliced are in the embodiment illustrated delivered to the slicing conveyor consisting of the slideway 91 along which the articles are carried by the flights 98. These flights are pivotally mounted on the conveyor chains 99, certain of the links of the conveyor chains being provided with brackets for the flight pivots |0|. The flights have supporting arms |02 which coact with the guides |03 for supporting the flights in upright position relative to the conveyor way 91, see Figs. 1, 3 and 9.
The feed conveyor delivers upon the feed table |04 across which the articles to be sliced are pushed by succeeding articles on to the bottom slicer feed conveyor. One of the side bars 49 is provided with an extension |05 disposed at the side of the feed conveyor opposed to the work table |06.
In the structure illustratedv the workman pushes the loaves from this table |06 on to the conveyor way 91 between the flights by which they are picked up and advanced and delivered, as stated, to the table |04. As the flight carrying brackets- |00 pass to the sprockets on the conveyor drive shaft |08 the guide arms |02 are released from the guide |03 and the flights tilt backwardly and drop through the space ||0 between the receivirg table |04 of the slicer and the end of the conveyor way, see Figs. 3 and 9.
The front side member of the slicing conveyor has an extension see Figs. l and 3, which shifts the loaves longitudinally, assuming that they have not been previously properly positioned, and properly centers them relative to the slicing conveyor. The spring fingers ||2 are provided on the side bars of the slicer feed conveyor, see Fig. 3, for the purpose of supporting the bread as it is picked up or engaged by the slicing conveyor. These spring fingers also serve to straighten up the loaf should it be presented at an angle as it is engaged by the bottom slicer conveyor.
The feed conveyor shaft |08 is driven from the sprocket chain |09 coacting with a suitable sprocket wheel on the sleeve |23. The sprocket chain |09 drives the shaft 08 through a sprocket wheel M3 which is rotatably mounted on the. flanged sleeve H4 and having a yielding driving connection thereto consisting of the spring pressed dog ||5 engaging a coacting recess IIE in the flange H1. The sleeve ||4 is keyed to a sleeve ||8 on the shaft and is adjustably connected to the shaft through the handwheel |I9. A spring pressed pin is mounted on the hand wheel to engage holes |2| in the flange |22 of the sleeve H8. This connection provides for a release or slippage of the conveyor drive in the event of the feed becoming jammed, the yielding driving connection being such that the machine is driven with a suitable degree of positiveness for ordinary operation but in the event of jamming the driving connection is broken or slips so that damage is minimized.
The adjustable connection enables the adjustment of the feed conveyor with the wrapper conveyor mechanism and enables the adaptation of the machine to loaves of different widths. The proper speed of the slicer conveyor is secured through the timing or variable speed gear 81.
The clutch |24 iscontrolled from a trip |25 disposed to project through an opening in the conveyor way 91, this trip being mounted on a rockshaft |26 connected by the link |21 to the clutch control member |28. The clutch is of such type that when the operator keeps the feed conveyor supplied with loaves of bread so that each flight carries a loaf and delivers it to the slicer conveyor the clutch remains in constant driving connection for the drive sleeve |23 to the shaft 86. However, in the event that a vacancy occurs in the conveyor load the control member |28 remains in position to disengage the clutch, thereby momentarily stopping the slicer conveyor.
In the event it is desired to continuously drive the slicer without regard to the feeding of loaves by the feed conveyor, for example, such as in clearing the slicer, the control member |28 is locked out of operative position by means of the dog |29 which coacts with the arm |30 on the rockshaft |26, these parts being conventionally shown in Fig. 1.
I have illustrated and described my improved slicing and feeding means in an embodiment which I have found highly satisfactory. I have not attempted to illustrate certain embodiments and adaptations or modifications thereof which might be desirable to meet different conditions as it is believed that this disclosure will enable those skilled in the art to embody or adapt my improvements as may be desired.
