Serial No. 474,905.
This invention relates to slicing or cutting apparatus and is characterized as comprising a cutting blade or knife formed to provide a cutting edge in the shape of a conical helix.
5 of articles and substances but it is herein illustrated as embodied in a machine which is designed and particularly adapted for use in slicing meats, such as for instance; pork and beef loins and chops, bacon or any other similar products of the meat packing industry, with or without bones therein, as ,machines constructed in accordance with the present disclosure have been found to serve well in this use.
It is an object of this invention to provide a slicing or cutting apparatus, which employs a continuous cutting motion in operation as distinguished from intermittent or reciprocating motions usually employed in slicing operations.
Another object of this invention is to provide a machine or apparatus which is extremely simple in construction and relative- 1y cheap to manufacture and one, the primary element of which is the cutting blade referred to with a rotary shaft for mounting said blade.
Another object is to provide a slicing or cutting apparatus which successfully rforms cuttin operations at a relatively high rate of speed, whereby the cutting capacity of the machine is greatl in excess of the capacity of the machines eretofore employed for cutting or slicing operations.
A further object of the invention is to provide slicing or cuttingv apparatus in which the location of the cutting action in roducing a single cut or slice, travels axialy with respect to the rotating cutting knife whereby a cutting contact betweenthe knife means at a constant and continuous rate of speed into the cutting apparatus with the production of uniform stralght slices or cuts by a continuous cutting motion. 7
A further object is to provide a cutting blade or knife shaped to provide a cutting edge formed as a conical helix in which the space between adjacent convolutions of the knife is greater than the thickness of the slices cut thereby.
In connection with the last stated object, it will readily ap ar that by employing a helical knife bla e having more than one convolution, that two or more cutting blades will be caused to simultaneously penetrate the object being cut whereby the intervening slices or cuts are caused to occupy thespaces between adjacent convolutions of the blade, and that unless special provision is made in the construction of the blade to provide additional space between adjacent convolutions, the enclosed cut or slice will be wedged into a space which is less than the thickness of the slice by an amount equal to the thickness of one cutting blade. Accordingly, by the present invention, a knife is provided of a special construction designed to produce cuts or slices of less thickness than the space between blades whereby the undesirable wedging referred to is eliminated and the slices are free to readily fall away from the location of'the cutting knife after the cutting operation is completed.
It is a further object of the present invention to provide a slicing or cutting apparatus of the character aving a single rotary knife or cutting blade of the character described, which is adapted to simultaneously perform a plurality of duplicate cutting 'actions, whereby. the ca acity of the a paratus is not only increase through the higher efficiency of the high speed continuous operation, but is also increased as the multiple of the number of operations being carried on at any one time.
It IS a further object to provide a slicing or cutting apparatus comprising a rotary knife of the above described character in which the thickness of the slices is determined b the pitch of the helix and further in whic the pitch may be varied or adjusted within limits whereby the thickness of the slices or cuts may be selected at will.
It is a further object of the present invention to provide in a cutting apparatus of the above described character, a knife having a cutting blade in the form of a conical helix constructed in such manner with relation to the article being cut so that in any single cutting operation, a portion of the knife remains in cutting contact with the article until the leading portion of the knife has penetrated the article in commencing a second cut, whereby a rtion of the knife is always in contact with the article and the cutting blade also serves as a conveyor for automatically feedin the article being cut into the cutting Inec anism.
It is a further object to rovide a cutting apparatus having in com ination with a knife, of the above described character, article holding means adapted to position and permit feeding of the article into the knife during the cutting operation at a constant and continuous rate of speed equal to the travel of the cutting contact between the blade and article whereby a cutting operation is carried on by continuous motion of the apparatus.
It is a further object of the present invention to provide a slicing apparatus having a plurality of cutting blades on a single shaft, each provided with a cutting edge formed as, or approximating a conical helix, together with means for positioning and feeding an article to be cut thereby at a constant and continuous rate of speed driven in synchronism with the rotations of the blades whereby the rate of advance of the article being cut is that which will advance the article an amount required to reduce a number of slices equal to the numher of blades on the shaft.
These and other objects not specifically enumerated are contemplated for the present invention and will readil appear to one skilled in the art, as the following description proceeds.
The resent disclosure is given merely by way o example and is not to be considered as limiting the invention in any respect, as the scope of the invention should be determined from the appended claims and from an understanding of the present disclosure and an appreciation of the advanta es which the invention produces therein.

The type of apparatus which is disclosed gin Figures 1 to 3 inclusive,-will be described rst.
In this form of invention, the helical cutting blade is provided with at least one complete convolution whereby the cutting contact between the knife and the article being out also serves to convey or feed the article into the cutting mechanism automatically and at the proper rate of speed.
By referring to the drawings, it will be noted that this form of invention is illustrated as embodied in an apparatus comprising a shaft 10, mounted in suitable bearings 11, supported by any suitable frame construction, not shown. The shaft 10, is provided with a pulley or other gearing element 12 through which rotation is imparted to the shaft. On the shaft, a hub 13, is provided rigidly fixed, attached for rotation, which hub is provided with a spiral groove 14, which serves as a mounting for the cutting blade or knife.
As more clearly shown in Figure 2, it will be noted that the cutting blade 15, is formed and arranged as a spiral helix with the outer edge 16 thereof sharpened to provide the cutting or knife edge.
Furthermore, the portions of the blade between the cutting edge and the hub are inclined or arranged on an angle as shown in Figures 1 and 3, whereb the space designated S in Figure 3, etwecn adjacent convolutions may be selected as greater than the pitch of the helix, designated P in Fi re 3.
e helical cutting blade may be mounted on the hub in any suitable manner such as welding in the groove 14 or b screws or similar fastening means and urthermore, the cutting blade may be made up in any desired manner such as by assembling a plurality of separately made parts.
Preferably, the cutting blade may be made up of a number of parts, each of which is substantially 360 degrees and formed to provide the final helical shape when the parts are assembled on the hub.
In associated relationshi with the cutting mechanism, an article hol er or positionin means 16 is preferably provided, position in the manner represented in Figure 1 so as to present articles to be cut by the apparatus in proper cutting relationship with the cutting blades. As the cutting edge conforms to a conical helix it will be observed that the axis normal to the cutting blade will be at a slight angle to the axis of the rotary shaft and therefore the article holding means 16 should be disposed at a slight angle so that the blades will slice or cut the article in transverse direction.
In the mechanism illustrated in Figure 1, it is particularly ada ted for slicing articles of meat, such as por loins or chops and is therein shown as the holder 16 inthe form of a tube of a size and sha adapted to conveniently contain and position a loin or strip of rk chops.
y inspecting Figure 1, it will readily ap pear that in operation the rota driven from a suitable source power to rotate in that direction which causes the spiral circumference to continuously increase. When so rotated, any article to be out, such as pork loin, is thrust forwardly in the tube 16 until the far end projects beyond the right hand edge of the tube as shown in Figure 1.
It will be noted that the tube is so adjusted with respect to the cutter that the upper surface of a pork loin when so presented is in position to be cut to some'extent by a smaller portion of the helical cutter. When the pork loin is thrust forward sufficiently the upper surface thereof comes in contact with that portion of the rotary knife which is of smaller diameter which accordingly starts a slicing cut. As the cutter continues to rotate, the pork loin is drawn forward by the action of the helical blade in the out already started so that eventually the slice is completed by a larger portion of the cutter. I
In the meantime, after the knife has made a complete revolution, the smaller portion of the blade starts a second cut and so on to provide a continuous cutting action while the cutter isloin is drawn through the tube 16 by the automatic feeding action of the cutter.
This action results in the rapid severance of successive slices until the loin or strip of chops has been completely cut or exhausted. m
It is contemplated that a second loin or other article to be cut, can be introduced into the holder 16 and fed forwardly immediately behind the loin being cut so that after the exhaustion of a particular piece, the operation may be continued without interruption.
The advantage of providing the space S between adjacent convolutions-of the cutting knife will obvious from an inspection of Figure 1,where it will be noted that the thickness of individual slices is determined by the pitch of the helix so that b providing the pitch P less than space S the individual slices are free from binding in the space S between adjacent convolutions.
Inasmuch as the'holder 16 occupies a. relatively small space, it is contemplated that other work holders 16 may be positioned in corresponding locations around the shaft so that two, three, four or any convenient number of holders may be provided, and as many pork loins or other articles sliced simultaneously. In such cases, the only additional provision necessary is that of some catching or conveying means for receiving the slices from each holding unit.
Referring now articularly to Figure 4, it will be observed t at a cutting mechanism is disclosed which is capable of varying the pitch of the cutting knife and therefore the thickness of slices to be cut. The blade in this modification is mounted in a groove 20 provided in the outer surface of a spiral s ring member 21. The spiral spring is esigned to have a greater end to end length than the length it will normally occupy in a position 0 maximum pitch ofthe helix whereby in all positions, when mounted for cutting operation, the spring 21, will be under some degree of compression.
The convolutions of the s rin 21 are formed as a true spiral where hy 51c correspondingconvolutions of the cutting blade will be positioned to form a true conical helix. The hub portion of this modification comprises a member 22, which is designed to be he ed [to a shaft for rotation and provided with internal threads 23 for receivin the threaded sleeve 24. The sleeve is provi ed with gear 25 on the outer edge thereof in mesh with a pinion 26, mounted for rotation in the socket 27, carried by the thrust collar 28; A straight sided opening 29 is 'provided in the gear, adapted toreceive a crank or other tool for rotating the gear and in turn, the sleeve 24. It will thus appear that the rotation of these parts causes the sleeve to move axially with respect to the hub 22 and by contact with the thrust collar 28 to impart a correspondirg movement thereto.
This adjustment is e ective to either compress or relax the spring 21, whereby it is caused to varythe distance between adja- 3 cent oonvolutions of the spr' and correspondingly, the pitch of the helical knife edge.
As it is desirable to maintain the exact itch between all convolutions of the cutting 1' Enife, allowance should be made for the varying cross section of the cutting knife, so
that the section modulus of the combined element namely, the spring 21 and the knife blades about the axis of flexure shall be constant.
In practice, this may be done by varying the cross section of the spring 21 from point to point whereby the spring will be correspondingly weaker throughout those rtions where increased strength is provided by the greater cross section of the cuttin blade. i In the modification shown in igure 5, a shaft is provided mounted in bearing 31, held by the frame 32, which shaft is provided with a hub 33 having a cutting blade 34 mounted thereon with a cutting edge in the form of a conical helix. The construction is more clearly shown in Figure 6 from which it will be noted that this cutting blade is 39 formed of less than one convolution. Accordingl a positive feeding means is provided which comprises a clamp 35, having projections 36 thereon, adapted to engage and hold the article to be out, such as a pork M loin or other strip of meat, or the like, 37
The direction of feed of the clamp 35 is determined by the threaded shaft 38 which has screw threaded engagement with the block 39 servin as a carrier for the clam 49 The threaded s aft is mounted in suitab e bearingscarried by the frame 32.
It will be noted that the shaft 38 is disposed on a slight angle to shaft 30 for the purpose of feedin the article to be cut in a position normaf to the eifective cutting edge of the blade. The effective service of the cutting blade at any one time is at a slight angle to the axis of rotation due to the helical formation thereof.
Intermediate shafts 40 and 41 are provided mounted in bearings 42 and 43 respectively. The shaft 41 is rovided with gears 44 and 45, the latter of which is in mesh with gear 46 on the shaft 30. Likewise, shaft 41 carries gears 47 and 48, the latter of which is in mesh with a gear 49 on the shaft 38.
Gears 44 and 47 are in mesh whereby the rotation of the driving shaft 30 by means of 7 suitable power applied to the gearing ele ment 50 on the end thereof, will serve to rotate the shaft 38 so as to effect a forward feeding of the clamp and the article being cut. The gearing in this modification is so 65 arranged with respect to the pitch of the and knife threads on shaft 38 that the article being cut will be fed forwardly for each rotation of the cutting knife an amount equal to the pitch of the cutting knife, whereby the feed 1 action is constant and continuous.
t will be obvious that this t pe of mechanism eliminates all necessity or reciprocab ing or intermittently movin parts and assures with great accuracy, s ices of constant, uniform thickness.
The modification illustrated in Figure 7 is quite similar in construction and operation with the exception that the clamp is held by a carrier 61 which slides on a bar 62. Bar 62 is stationary and the forward feeding movement is imparted to the carrier by means of the yoke 63 which on ages the pin 64, mounted on the carrier. he yoke in this modification is provided with a threaded hub 65 in engagement with the threaded shaft 66 which is driven b means of gears 67 and 68 from the main s aft 70, on which the cutter is mounted. in this form, power may be transmitted to the shaft 70 throu b any suitable mechanism not shown, w ereby the pork loin or other an.
ticle bein cut will be advanced in the manner described in Figure 6.
Here also, the gearing is adjusted to provide the forward feeding of the article being cut at a rate equal to the pitch of the feeding screw for each revolution of the main shaft 70.
In the modification shown in Figures 8 and 9, a plurality of cutting blades 86 are shown mounted on a hub 90, fixed to rotate with the shaft 91. The shaft 91 is held in suitable bearings 92 in the frame 93. In this form, the cutting blades which are less than one hundred and eighty degrees in size, are located at an angle as shown in Figure 8, but are of substantially straight lormation instead of strictly conformin to the formation of a conical helix. This orm is shown by way of a suitable embodiment of the invention and the deviation from the strictly helical form is permitted for the purpose of manufacturing convenience and with the result that the variance is insuilicient to produce any substantial difference in the cutting action.
The angular dis sition of the cutting blade is such that t e oint of cuttin contact at any one time a vances forwar ly in substantially the same manneras that of a true helix. It will therefore appear that where the blades are of relatively small arcs in size, that variance to the straight but angularly disposed blades may be permitted without substantial change or efiect upon the operation.
In this form, two cuts or slices are completed for each rotation of the shaft Hl and accordingly, the clamp 94 holding the loin or other article 95, is fed forwardly at a rate suflicient to expose a uantit of the alrticle to the knives sufficient to produce two s ices.
In other words, the rate of feed is twice that of the rate in the device shown in Figures 5 and 7. The forward feedin is accomplished by means of a rotary t readed shaft 96, on which is mounted the threaded collar 97, having a carrier 98 for the clamp 94 rigidly attached thereto. ,The shaft 96 derives its rotary motion from a gear 97 and chain 98 in mesh with a gear 99 mounted on shaft 95. The shaft may be rotated by any suitable gearing means from a source of power not shown.
As shown in Fi re 9, a suitable tray 10( may be positione with respect to the cutting blades to maintain the loin or other article in proper feeding position with respect thereto.
From the above description of the various modifications of this invention, it will readily appear that the applicant has disclosed a new and improved type of slicing and cutting apparatus which possesses the advantages enumerated therefor and fully accomplishes all of the above stated objects.
