19 Claims.
This invention relates to a multiple blade and blade frame assembly for slicing machines and more particularly to such assemblies for 'use in bread slicing machines.
One of the objects of the present invention is to provide a multiple blade and frame assembly for slicing machines with new and improved means for placing the cutter blades under substantially uniform tension.
Another object is to provide such assemblies with means for placing the cutter blades under substantially uniform and continuous tension.
Another object is to provide a blade frame having a plurality of spaced cutter blades mounted thereon with compression springs for placing the individual blades under tension, all of the springs having substantially thesame characteristics.
A further object is to provide a blade frame having a plurality of cutting blades mounted thereon with new and improved means for mounting the blades which will permit easy assembly of the blades to and disassembly from the blade frame.
With the above and other objects in view, which will be apparent from the following detailed description, the present invention consists in certain features of construction and combination of parts which will be readily understood by those skilled in the art to which the invention appertains.
Reference should be had to the accompanying drawing, which illustrates a suitable embodiment -of the invention, in which:
Figure l is a front elevation of a blade frame showing a plurality of cutter. blades mounted thereon, a number of the blades being removed;
Fig. 2 is a Vertical section taken approximately on the line 2-2 of Fig. 1;
Fig. 3 is an enlarged fragmentary section taken through the blade frame showing the mounting of the cutting blades in greater detail;
Fig. 4 is a fragmentary front elevation of the construction shown in Fig. 3;
Fig. 5 is a view similar to Fig. 4 showing a modified mounting means for the cutter blades; and
Fig. 6 is a fragmentary perspective view of one of the bolts employed for placing the cutter 50 blades under tension.
In slicing machines of the construction used for commercially slicing baked bread'and other baked products, it is common practice to employ two series of cutter blades so arranged that 55` While one series is moving in one direction the other series is moving in the opposite direction, and furthermore so that each blade in one series is positioned between a pair of blades in the other series in order that the blades of both series will substantially simultaneously engage the article to be sliced.
In order to arrange the cutter blades in this manner two blade frames are employed to simultaneously reciprocate in opposite directions, each of the blade frames having a series of spaced cutters. The present invention, however, is directed to a new and improved means for mounting the cutter blades on the blade frame in such manner that the proper tensioning of the blades is obtained.
Referring to the accompanying drawing, in which like numerals refer to like parts throughout the several views, the blade frame preferably comprises a single piece casting of suitable metal which is provided with upper and lower head pieces I and 2, respectively, and side pieces 3 integrally interconnecting the head pieces I and 2.
The head pieces I and 2 preferably gradually increase the depth from the side pieces 3 to-` ward the center of the frame in order to give adequate strength thereto. The increase in thickness of metal occurs outwardly of the planes of the ends of the side pieces so that the metal of the head pieces will have a tendency to be placed under compression when the cutter blades 4 are properly mounted on the head pieces. By providing head pieces of gradually increasing depth, material deection of the head pieces is prevented.
The mounting means for anchoring the blades II to the lower head piece 2 comprises a number of anchoring plates 5 secured by suitable screws 6 to the head piece 2, spaced flanges 'I preferably being provided on this head piece to insure the proper positioning and alignment of the mounting plates 5. The mounting means, however, may comprise a single member. Each plate 5 carries a number of outwardly projecting lugs 8 spaced according to the blade spacing and each lug is formed with a slot 9 of sufficient width to receive the endof the blade 4. The lower sides of the lugs 8 at each side of the slot 9 are formed with recesses I0 which receive the buttons II provided at the lower ends of the blades as shown in Figs. 3 and 4. Y
The mounting means for anchoring they upper ends of the blades 4 to the top head piece I also comprises either a single or a number of mounting plates I2 secured by suitable screws I3 to the head piece I. These plates are preferably formed with a rib I4 which seats within a recess or groove I5 extending longitudinally of the head piece to insure the proper positioning and alignment of the mounting plates I2.
'I'he plates I2 extend below the head piece I as indicated in Figs. l and 3 and are also provided with outwardly extending lugs I6 which are aligned with the lower lugs 8. The lugs I6 are preferably provided with slots I'I, aligned with the slots 9 of the lower lugs, and which receive the upper ends of the blades 4.
Bolt openings I 9 are provided through each plate I2 above the upper horizontal faces I8 of the lugs I6, and the upper ends of the blades are supported upon bolts 2| which extend through the openings I9, the outer ends of the bolts being formed with enlarged rectangular head portions 22 which are supported on the horizontal lug faces I8. These enlarged head portions 22 are provided with slots 23 which also receive the blades 4.
The upper surfaces of the head portions are tapered at 24, the taper being inclined from the outer end of the head portion toward the bolt axis for engagement with the projecting buttons II at the upper ends of the blades.
Also, preferably disposed above the lugs I6 are slotted shorter lugs Ia having Vertical abutment faces ISa which are engaged by the buttons I I carried at the upper ends of the blades 4.
The inner end of each bolt 2I which extends through the plate I2 is provided with a nut 25 and washer 2S, a coiled spring 2 being carried by the bolt and disposed between the plate I2 and washer 26 to continuously tend to draw the bolt through the plate opening i9. This tendency, because of the inclined portion '24 of the head 22, exerts a continuous pressure upwardly against the blade buttons II, thus placing the blade 4 under tension, the buttons II also abutting against the vertical faces ISa of the lugs I 6a which are in alignment with the buttons to serve as abutments. In other words, the head portion 22 of the bolt 2l acts as a wedge which, by reason of the continuous tendency of the bolt to be drawn through the mounting plate I2 acts directly against the blade buttons II and places the blade under a continuous tension. The angle of inclination of the inclined face I2 of the head portion is such that the bolt will have a full freedom of movement through the bolt opening regardless of the force exerted against it by the blade buttons EI so as to avoid binding action or sticking of the bolt.
All of the blades 4 are mounted in the same manner and it is desirable that all of the springs 21 have the same characteristics so that all blades will be subject to a continuously acting tension.
In order to provide for an easy removal or assembly of the blades to the blade frame, each of the bolts 2I is formed with a recess 28 adjacent the head portion 22 so that when the nut 25 is loosened or removed or when the spring is compressed and the recess 28 is disposed outwardly of the Vertical faces I8a, the buttons II at the upper end of the head Will drop into the recess 28 so that the buttons I I at the lower end of the blade will clear the lugs 8. In other words, Whenever the bolt 2| is in such position that the buttons II at the upper end of the blade 4 drop into the groove 28, the blade can be easily removed by merely swinging the lower end of the blade outwardly from within the slot 9 of the lower lugs 8 and then bodily lifted from the supporting bolt 2I.
In the construction shown in Fig. 5 the mounting is identical with that just described with the exception that the blade slots 30 formed in the lugs I5 are inclined from the vertical with respect to the slots in the bolt heads 22a. so that the blades 4 will be engaged by opposed corners of the blade slots 30. The slots in the lower lugs which receive the lower ends of the blades 4 may be similarly inclined if desired. The inclined slots will assist in reducing vibrations of the blades and also minimize the tendency of the ends of the blades to move sidewise or to twist.
Furthermore, should the blades stretch in their operation the springs have suicient compression characteristics to always maintain the blades under tension, thereby tending toward the elimination of blade breakage which frequently occurs from improperly tensioned blades.
Although a certain type of blade frame and plate supporting means is shown and described, it is to be understood that the present invention is applicable to other types of blade frames and blade supporting means.
Furthermore, it is to be understood that the particular form of apparatus shown and described, and the particular procedure set forth, are presented for purposes of explanation and illustration and that various modifications of said apparatus and procedure can be made without departing from my invention as dened in the appended claims.
