Operatively mounted at their ends on, and extending trans-l versely between, the chains 44, is a plurality of spaced parallel bars 58 each provided with a tatably supporting guide'rollers 54, 55, respectively. Outwardly to one side ofthe guide roller 54, each plate 5,! is provided with a preferably integral forwardly extending slide-boss 56 and correspondingly. outwardly to one side of the guide roller with a similar rearwardly projecting slide-boss 51, all as best seen in Figures 1 and 3 and for purposes presently more fully appearing.
Mounted on, and extending inwardly of the machine from, the posts 29, 29, just aboye the plane of the forward or lower run 46 of the conveyor chains 44, are horizontally extending arms 58 supporting at their inner end a horizontally disposed guide-track 53 having a vertically extending roller-engaging rail 60 and a horizontally extending boss-engaging rail '6 I. The guide track 59. extends initially longitudinally along, a side margin of the conveyor table [4 for a short distance, as at 62, is then bent to extend obliquely inwardly of the table 14, as at 63, and finally is bent to extend longitudinally forwardly, as at 64, again in parallelism with the longitudinal axis of the conveyor table l4. At its rear end-portion, the straight section 62 of the track'59 is provided with an upwardly curled lead guide G5 for initially engaging the slide-boss 51 of the respective pusher-plates 55 for smoothly directing the same successively into operative engagement With the track-railfi l,
Similarly. mounted at its extremities upon, and
extending horizontally just above the plane of the return run 45 of the conveyor chains 44 between, the posts 38, 30, is a return track 65 having an inwardly extending oblique section 61 paralleling the oblique section 53 of the track 59 and a straight section 63 paralleling and correspending with the straight section 62 of the track 5? the track 6%; being at its rear end provided preferably integrally with an L-shaped bracket extension 69, all as best seen in Figure 1 and for purposes presently appearing.
Each of the pusher plates 5! is provided with a relatively large longitudinal slot or opening "iii having along its lower horizontal margin an enlarged annular bead 'H for slidably accommodating a complementarily shaped spring metal clip 12 provided with a forwardly projecting arcshaped end gripper 13, all as best seen in Figures 3 and 6 and for purposes presently more f'uily appearing.
Mounted on the rails i3 a short distance forwardly of the posts 29, 35, is a pair of transversely aligned upstanding brackets '14 each provided with a tubular sleeve 15 for shiftably accommodating guide supporting arms 16 each, in turn, provided at its inwardly presented end with an enlarged frusto-conical head 11, and each secured adjustably in its sleeve 15 by a set-screw or the like 78.
Similarly mounted on the side rail is a short distance rearwardly of the posts 29, 30, is a pair of transversely aligned brackets 19, each provided with a tubular sleeve 86. for accommodating guide supporting arms 84 disposed substantially parallel to the arms if, and each likewise secured adjustablyv in position by means of a set-screw or the like 82 engaging the sleeves 8i). Pivotally mounted upon the inner end of the respective arms BI, is a shiftable guide 83 having a forwardly extending straightlsection 84 projecting preferably, as shown, over the discharge end of the table I 4 of the transfer conveyor assembly B, a rearwardly and obliquely outwardly extending section @355, and a rear straight section 86 extending in parallelism with the adjacent side rail I3 and having an aperture, as at 81., positioned and sized for freely accommodating one of the transversely disposed guide supporting arms 16, all as best seen in Figures 1 and 4 and for purposes es y fully appearin 88 designates a straight guide provided longitudinally upon its outwardly presented face and intermediate its ends with a block 89 having a dovetail slot 98 for slidable engagement with the frusto-conical head 71 of the arm 76. At their respective forward end, the guides 88 are, bent slightly inwardly of the machine, and each provided upon its outer, face with a C-shaped slide clip 9! sized for snug-fitting 'shiftable engagemerit around they oblique section of the shifting guide 83, all as best seen in Figures 4 and 5 and for purposes presently fully appearing.
At their respective rearward end, each guide 38 terminates a substantial distance forwardly of the delivery plate 8 and is provided with a long tudinally extending slot 92 for shiftably accommodating a wing-screw 93 mounted in a short extension-guide 84 extending obliquely upwardly across the delivery plate 8, all as best seen in Figure 2 and for purposes presently fully appearing.
Welded or otherwise; fixed upon the forward end of the, divider plate II and extending horizontally over the conveyor table I4, is a free swinging switching guide95. constructed preferably of relatively flexible steel or other suitable material and terminating at its forward or free end between the forward straight sections 84 of the shifting guides 83, the guide 95 being of suficient length to swing obliquely from side to side into contact at its free end with the respective switching guides 83 at a point slightly forwardly of the juncture line between the straight sections 8 and the oblique sections 85 thereof, all as best seen in Figures 1 and 7 and for purposes presently fully appearing.
In use and operation, the set-screws 82 are loosened and the guide supporting arms 8! adjusted transversely of the table 54, so that the forward straight sections 84 of the shiftable guides 83 are spaced apart by a distance substantlally equal to the length of the particular loafportion or loaf-fraction to be delivered into the conveyor C of the wrapping machine W.
Similarly the set-screws 78 are loosened and the guide arms 16 shifted transversely of the table 34, so that the straight guides 88 are each spaced equidistantly from and on opposite sides of the divider plate II by a distance equal to the length of the particular loaf-portions or loaf-fractions to be conveyed and wrapped, the guides 88 being also simultaneously shifted lengthwise to maintain proper adjusted relation with the oblique sections of the shiftable guides 83 at the clips 98. likewise shiftably adjusted longitudinally so as to extend across the delivery plate 8 in substantial proximity, at their rearward extremities, to the knives of the slicing head 2.
As the loaves L are successively fed through the slicing head 2, the sliced .loaves L are discharged in succession across the delivery plate 8 between the extension guides 94 and each subdivided into fractions Z, Z, by the divider plate ii. Thereupon, the fractions Z, Z, of each loaf L are simultaneously picked up by a flight rod 2% and progressed forwardly over the table l4. As such loaf fractions Z, Z, pass between the posts 29, 39, one of the pusher blades 5| drops downwardly behind the fraction Z. viously stated, the chains M and the associated pusher plates 5i are moving at approximately twice the speed of the flight rods 2!, the loafportion or fraction Z will be accelerated sharply and advanced ahead of the slower moving fraction Z, which continues its forward movement under the influence of the particular guide rod 2i. As the particular pusher plate 51 is moved forwardly, its slide boss 5'! engages the under face of the track 6i, thereby holding such pusher plate 5i against swingable movement on its supporting rod 5% and simultaneously the roller 55 rides against the track face 60, thereby shifting said pusher plate 5| transversely inwardly and disposing the end gripper 13 into facewise abutting engagement with the outer end face of the particluar loaf fraction Z approximately at the instant at which the same moves forwardly away from the straight guide 88 and against the oblique section 85 of the shifting guide 83. As the loaf fraction Z is progressed further forwardly, it is shifted toward the center of the conveyor table M as a result of the combined forward movement of the pusher plate 5| and the oblique direction of the shifting guide section 35, the end gripper l3 serving to prevent unauthorized tilting or misalignment of the loaf slices at the outer end of the particular loaf-fraction Z. Meanwhile the inner or crustless end face of the loafraction Z moves into engagement with the switch- The extension guides 94 are Since, as preing guide 95, which, being sufliciently flexible to bend under the pressure exerted by the loaffraction Z without materially deforming the crustless end face thereof, will initially assume a shape somewhat as shown in full lines in Figure 7. In fact, frequently the crustless end slice of the loaf-fraction Z swings outwardly into more or less flush engagement along the switching guide 95, as shown in dotted lines at :c in Figure 7.
As the particular loaf-fraction Z moves forwardly between the straight sections 84 of the shifting guides 83 for discharge into one of the pockets of the wrapping machine conveyor C, such particular pusher plate 5! swings upwardly and rearwardly as the chain 44 passes over the forward sprockets 3i and moves rearwardly along the return run $5, the roller 52 coming into engagement with the track 61 and causing such pusher plate 55 to be again shifted transversely during the course of its rearward travel to initial position for engaging a subsequent loaf-fraction Z, all as best seen in Figure 3.
Meanwhile the loaf-fraction Z of the one sliced loaf L has been moved forwardly by the flight rod 2! and comes into engagement with the rearward portion of the switching guide 95, deforming the latter to approximately the position shown in dot-dash lines in Figure 7 and actually pulling the free end of the switching guide away from engagement with the preceding loaffraction Z and thereby materially speeding up the fractionating operation, the particular portion or fraction Z', in turn, being discharged in consecutive order between the guide-sections 84 into the wrapping conveyor C. Thus the fractions or portions of the several sliced loaves L are in consecutive order and in predetermined timed relation fed automatically to the machine W for wrapping and further handling.
It will also be evident that the transfer conveyor assembly B may be very quickly and simply adjusted for transferring unfractionated sliced loaves or portions of loaves if, for some reasons during production, it becomes desirable to package a predetermined number of unfractionated loaves. plished simply by removing the divider plate II and its associated switching guide 95. At the same time, the pin-clutch 42 may be disengaged for effecting a cessation of movement of the chains 44 and the associated pusher plates 5!. In most instances, the chains 44 will come to rest in such a position that one or more of the pusher plates 5! are in downwardly disposed loaf-pushing position. Such plates, therefore, may be swung forwardly and upwardly out of the path of the unfractionated sliced bread loaves and pushed laterally along the rods 5i], so that a corner thereof will rest upon the upper margin of the guide track 59, the pusher plates 5| being thereby retained in such upwardly disposed inoperative position.
