FEEDING MECHANISIVI.

Specification of Letters Patent.

Patented A110. 22, 1911.

Original application led March 24, 1909, Serial No. 485,492. Divided and this application filed August 3,

To all whom it may concern:

Be it known that I, JAMES J. SULLIVAN, a citizen of the United States of America, and a resident of Elmhurst, county of Queens, and State of New York, have invented certain new and useful Improvements in Feeding Mechanism, of which the following is a.

specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in feeding mechanism, and particularly to mechanism for feeding plastic material and to means operating in conjunction therewith for controlling mechanism arranged to act upon the material so fed forward.

In a co-pending application, Serial No. A4E85,t92 filed March 24, 1909, of which the present application is a divisional, I have shown a complete machine for feeding plastic material, for segregating the material into articles of a predetermined form and shape, for wrapping such articles with a suitable wrapping material such as tin foil, and for preparing labels and applying them thereto.

rIhe present invention relates to that part of the apparatus embodied in the feeding mechanism and the controlling means operated in conjunction therewith, and particularly to mechanism by which the feeding of the material and the subsequent operations upon the material so fed are both controlled by the forward movement of the material itself.

In the feeding of plastic material such as yeast, ice cream, and the like, the amount of material fed forward during a predetermined movement of the machine is largely dependent upon the consistency of the material,-the decreased resistance offered by a thinner material causing less material to be fed forward than occurs where the material is thicker or of a heavier consistency.

' In a co-pending application Serial No 480,7 58, filed March 1, 1909, such application being a renewal of an earlier application, Serial No. 386,598, filed August 1, 1907, I have disclosed means for feeding forward plastic material, the feed being discontinued by means controlled by the forward movement of the material itself, but the mechanism for operating upon the material so fed forward is independently started into operation at predetermined intervals of Serial No. 510,972.

time. The predetermined intervals of time are necessarily of sufficient duration to permit of the feeding of the thinnest material and consequently a certain amount of time is lost at each cycle of operation, and this results in a large total loss of time.

The main object of my present invention is to obviate this loss by not only controlling the feeding means by the movement of the material, but also by controlling thereby the mechanism by which the material so fed forward is later acted upon.

To this end my invention consists in many novelfeatures of construction, and combinations of parts, and to the end that my invention may be fully understood, I will now proceed to describe a machine in which thev same 1s embodied, reference being hadto the accompanying drawings illustrating the same, and will then point out the novel features in claims.

In the drawings: Figure 1 is a top view of the machine. Fig. 2 is a view in central longitudinal section, the section being indicated by the line 2-2 of Fig. l. Fig. 3 is a view in side elevation of the machine, with a portion of the bed plate broken away.

'Fig 4 is a view in vertical transverse section upon the plane of the line 4-4 of Fig. l. Fig. 5 is a view in horizontal section yupon the plane of the line 5 5 of Fig. 2,. with portions of the bed plate broken away beneath the plane of section. Fig. 6 is a detail underside view in horizontal section uponv the plane of the line 6-6 of Fig. 2. Fig. 7 is a detail view of certain of the operating parts, the plane of section being upon the line 7--7 of Fig. 5.

It will be understood that in a cycle' of operation in a complete machine, two sets of operations take place; first, that in which the material is fed forward, and second, that in which the portions ofthe material are segregated, wrapped, labeled and delivered. During the time the feeding mechanism is in operation the other mechanism is at rest, while during the time the segregating, wrapping, labeling and delivering mechanism is operated, the feeding mechanism is at rest.

rIhe mechanism for driving the parts is as follows: The drive' shaft is located beneath the bed plate 26 of the machine, being journaled in suitable bearings secured to the said bedplate, and is provided Vwith a suitable pulley 27 by which it may be driven. The said pulley is, however, mounted loosely upon the shaft, but is adapted to beconnected in driving relation therewith by means of a clutch member 28 which is secured to the said pulley, and a complementary clutch member 29 arranged fast upon the shaft 25. At the opposite end of the shaft to that at which the pulley 27 and

clutch members

28 and 29 are located,

the said shaft is also provided with a miter y shaft 38 of the feeding mechanism 39. rIhev 'i feeding mechanism comprises a suitable receiving hopper 40 for the reception of material to be wrapped, which in the present case may be a plastic material such as yeast, stirring blades 41 for acting upon the mass to thoroughly miX the same, a feed screw 42 '"for feeding the material forward, and a discharge nozzle 43 through which the materialis adapted to be fed toward the wrapping or other mechanism. The stirring blades 41 and the feed screw 42 are mounted upon the said shaft 38 and are rotated by the driving mechanism just described in a direction to feed the material toward and through the nozzle 43. The feed of the material continues for so longa time as the drive shaft is connected in operative driving relation therewith through the

clutch members

28 and 29,but will cease immediately the said clutch members are disengaged. This disengagement is brought about automatically by means of the material which has been discharged through the nozzle 43 when a predetermined quantity of the material has been so discharged,

and is effected in the yfollowing manner :l

path of transverse movement of a pivoted shipper lever 47, the lower end of which engages a shipping bar 48. The Vshipper bar is arranged in engagement Y with a pivoted clutch operating lever 49, the lower end of vwhich engages a collar 50 which is secured to the drive pulley 27. The drive pulley 27, which, as has already been stated,-

is mounted torrotate loosely upon the shaft 25, is permittedV a slight longitudinal play uponA the said shaft and a spring 51 normally eXerts tension to pull the shipper bar 48 in a direction to move the pulley 27 toward the left (as viewed in Fig. 4) to disengage the clutch member 28 from the clutch member 29. llhen, therefore, the abutment 46 is moved by the engagement of the material as it is being fed forward in the machine so as to clear the shipping lever 47,7the said shipping lever will be permitted to swing over to the left (as viewed in Fig. 4) permitting the bar 48 to move over to the right and the pulley 27 and clutch member 28 over to the left. All feeding movements will now immediately cease, butthe foregoing movement, in addition to disengaging 'the

clutch members

28 and 29 will have the effect of engaging other clutch mechanism so as to thereafter immediately commence to drive the other parts of the machine. The other said clutch mechanism comprises a clutch member 52 which is sewhich is carried by an intermediate shaft 57 mounted in suitable bearings beneath the bed plate of the machine parallel with thev d-rive shaft 25. The intermediate shaft 57 is provided at one end thereof with a bevel pinion 58, the teeth of which are arranged in mesh with a bevel spur gear 59 disposed upon a vertical shaft 60. The vertical shaft 60 passes through the bed plate 26 to a point above the said bed plate and is provided with two mutilated gear wheels 61-62. The lower of the mutilated gear wheels 61 is arranged to engage a pinion 63 which is mounted fast upon a vertical shaft 64 in the central line of the machine. The shaft 64 is also provided at its upper end with a pinion 65, the said pinion being arranged in mesh with a spur gear 66 mounted loosely upon the central post 67 ofthe machine. The spur gear 66 vis also arranged inY mesh with certain other pinions 68-69-70 which are disposed concentrically around the central post 67 as will be seen by reference to Fig. 5, whereby the movement imparted to the shaft 64 and pinion 65 will be partaken of by the said pinions 68--69-70.

At its lower end the shaft 64 is provided with a bevel gear 71 which is arranged in vmesh with a complementary bevel gear 72 Secured upon a short shaft 73 which is journaled in suitable bearings beneath the bed plate 26 of the machine and which isYY disposed longitudinally in the central line of the machine.

At its rear end the saidV shaft 73 is provided with a bevel gear 74 transverse shaft 76. The said shaft 76 is provided with a cam 7 7 which is housed in a yoke 78, the said yoke being connected to a cross-head 79 which carries a cutter 80 for cutting off a predetermined quantity ofthe material which has been fed through the nozzle 43. The cutter 80 may be of different characters in accordance with the character of material to be acted upon; when a plastic material such as yeast is employed, such cutter preferably comprises a shortsection of wire 81 (see Fig. 4) held taut in a position to engage the material when the cross head is moved in either direction by means of a yoke 82. Normally the cutter- (in this case the wire 81), is held at rest just below or above the path of movement of the material as it is being fed from the nozzle 43, but directly the feeding ceases by reason of the tripping of the clutch mechanism by the material itself as has been explained above, and the train of gearing through the pinion 55, spur gear 56, shaft 57, bevel pinion 58, bevel spur 59, vertical shaft 60, and mutilated gear 61 has been set in motion, the said mutilated gear will promptly engage the pinion 63 so as to rotate the vertical shaft 64 and thereafter through the train of gearing including the bevel gears 71 and 72, shaft 73, and bevel gears 74 and 75, rotate the shaft 76 and with it the cam 77 whereby to impart a rapid movement to the cross head 7 9 through the medium of the yoke 78 so as to cause the cutter to move in one direction or the other across the body of the material in front of the nozzle (see Fig. 3) and thereby to cut off the front portion of the material so as to segregate the same, and to present such portion in the form of a rectangular unit or cake, as it is called, to the receiving and Vwrapping mechanism to be Wrapped, labeled and delivered or otherwise acted upon. r1`he receiving means for the segregated cake comprises two fingers 83 which are pivotally mounted upon a slide 84. r:[he said slide 84 is radially mounted in a turn table 85 which is mounted to rotate freely upon the central post 67. 1t may be here noted that there are a plurality of these slides withY their appurtenances, mounted in the said turn table, six being shown Vin the present instance, and that a step by step movement is given to the turn table to bring each of these slides in order, in line with the material being f ed. As all of these slides and their appurtenances are precisely similar, a description of one will serve for all, but it will be understood that the particular slide referred to in the following description is the one which is now in line with the hopper nozzle. The said slide is mounted in a suitable guideway so Vthat it maybe freely moved radially in the said turn table. At its lower face the said slide isV provided with two dependent flanges 86-87, the contiguous faces of the said iianges being spaced apart so as to receive a stud 88 with which the pinion 65 is provided. The said fingers 83 are provided with short arms 89 by which they may be operated, the said arms being pivotally connected to an operating rod 90 which extends longitudinally along the frontface of the slide, and the said operating rod is provided with a dependent finger 91 which passes down through a suitable opening in the said slide 84 to a position between the stud 83 and the face of the fiange 87. A spring 92 normally operates to pull upon the said operating rod 90 in a direction toward the central post 67 so as to swing the fingers 83 in a direction toward each other. The normal rest position of these parts is with the slide retracted to its inner position toward the center of rotation of the turn table and with the operating rod 90 retracted so as to cause the fingers 83 to be moved toward each other. The parts are so shown in Figs. 2 and 3 of the drawings and are in such position while the material is being fed for-l ward and preferably up to the time such feeding movement ceases. Immediately the shaft 64 commences to rotate in the manner aforesaid to accomplish the cutting off of the material the gear wheel 65, rotating therewith, carries the stud 88 around in a course concentric with its center of rot-ation and the said stud in its movement operates to move the slide 84 forward in a-direction toward the hopper nozzle 43. At the moment of its .first movement it will engage the dependent finger 91 of the operating bar 90 thereby operating to move the fingers 83 apart so that as the slide `moves forward the fingers 83 will be slightly spread. The movement of the slide will be sufficient to carry the fingers to a position upon either side ofthe portion of the material which is being segregated and the first movement of the stud 88 as it passes the central line of the machine upon its return movement will release the operating rod thereby permitting the spring 92 to retract the same and to cause the fingers to move together to embrace and hold the said material. At just about this moment the section of material will have been entirely segregated so that upon the return movement of the slide the segregated cake will be drawn back as the slide moves back to its first position. The mutilated gear 61 is so proportioned with relation to the pinion 63 with which it engages to rotate the shaft 64, as to impart exactly one revolution to the said shaft 64 at each operation so that the aforesaid driving movements will effect one complete reciprccatingmovement of the slide, the first half or forward portion of such movement lbeing' synchronous with an operative movenozzle 43, engages the finger 44 to thereby cause the plate 45 to move toward the cential post 67. This is a movement relative to the slide but the slide is held against movement at the time by the stud 88. When the forward feed of the material ceases, further movement of the finger 44 and plate 45 ceases; and thereafter when the movement of the stud 88 compels the forward movement of the slide 84 such movement is again a relative one with respect to the finger 44 and slide 45, and the extent of such movement is suiiicient to bring the fingers 83 in front of the finger 44 so that while the fingers 83 embracethe sides of the material, the face of the material is immediately adjacent to the forward face of the finger 44, and when the stud 88 upon its returnenovement retracts the slide, the plate 45 and finger 44 will be retracted therewith. It will be understood that in the complete wrapping machine, a piece of wrapping material will have been fed to a position between the segregated unit or cake, and the finger 44 of the slide 45, and that the relative movement between the slide 84 and the linger 44 by which the fingers 83 are projected beyond the face of the finger 44 will not only result in the grasping of the cake but also in the bending of the wrapping material into trough-like form around the cake. I will not, however, go into any further detail as to the operation of folding the wrapping material around the cake as the same forms no part of the present invention, but the said co-pending application Serial No. 485492 may be referred to for a complete understanding of the entire machine. The transfer of the cale and the receiver from one position to another in the machine is brought about by a step by step movement of the turn table 85, the extent of such movement being, in the present instance, T1,.- of a revolution at a time. The turn table is so moved by means of the mutilated gear 62 which engages at the proper time a pinion 96, the said pinion being secured upon a vertical'shaft 97 which also carries a pinion 98, the teeth of which are disposed in mesh with teeth 99 upon an apron 100 which is dependent from, and secured to, the said turn table 85. The relationship `of the teeth of the mutilated gear wheel 62 with the teeth of the -pinions 96-97 and the teeth 99 of the turn table 85, is such that a portion of the said mutilated gear wheel will produce just exactly one-sixth of a revolution of the said turn` table, and the time at which the teeth of the mutilated gear wheel 62 engages the pinion 96 is after, and preferably immediately after, the mutilated gear wheel 61 has completed its engagement with the pinion 63, wherein the vertical shaft 64 has made one full revolution. Directly the turn table has completed its one-sixth of a'm'ovement so as to bring a new slide into line with the hopper nozzle it is necessary to shift the drive from its connection through the

clutch members

52 and 53 with the mechanism last described, to its connection through the

clutch members

28 and 29 with the feeding mechanism. This is accomplished by the abutment 46 of the plate 45, which in the last portion of themovement of the turntable comes into engagement with the shipping lever V47 as will be readily understood by reference to Figs. 3 and 4 of the drawings, so as to move over the said lever 47, back to the position in which it is shown in Fig. 4, thereby shifting the shipper rod 48 over to the left, as is viewed in Fig. 4, against the tension of the spring 51 and roclringrthelever 49 upon its pivotal support so as to slide the elements 50-52 and 28 upon the shaft 25 whereby to disengage the clutch member 52 from the clutch member 53 and to cause the clutch member 28 to engage the clutch member 29. In order to positively stop the movement of the turn table at the right moment and to prevent overrunning thereof due to the momentum of the moving parts, I have provided a pawl 122, the end of which is adapted to engage a shoulderedv portion 123 provided at the rear of the bevel wheel 59 upon the vertical mutilated gear shaft 60, said pawl being drawn out of engagement with the said shoulder when the shipper rod is moved to a position to cause the turn table to be driven, and permitted to engage the said abutment when the shipper rod is moved in the opposite direction.

After a segregated cake has been received within a receiver in the carrier it is carried to different points in the machine in the movements of the carrier and is wrapped and labeled, or otherwise operated upon, as may be desired, and vfinally, delivered. In' the present machine the side and end folds up to, but not including the turning over of the projecting folded ends, are completed at a point in the machine one-sixth of a revolution of the turn table in advance of the point at which the cake is received, Vthe mechanism being driven by thepinion 68. The Yprojecting folded ends are folded'down while the turn table is moving through the next one-sixth of its revolution, and at the next stopping place a label applied by mechanism driven from the pinion 69. The completely Wrapped and labeled article is delivered when the turn table has completed its next one-sixth of a revolution, the point of` delivery being exactly opposite to, and in a line with, the feeding nozzle. The delivery is effected by means of the pinion 70 which is provided with a stud 202 arranged to engage the slide when it is at its delivery position, in the same manner as the stud 88 engaged the slide when it was at its first position. The slide in being brought to the delivery position receives the stud 202 between the dependent flanges 86 and 87, and when the pinion 70 is rotated the slide is given a reciprocating movement in a radial direction with respect to the turn table. A receiving chute 203 is arranged at this point, the inner bore thereof being of a proper size and shape to receive the wrapped and labeled articles. rlhe slide in its reciprocation forces the article into the chute, and a pawl 204 retains them in position there-in. In its return movement the slide will bring back with it the plate 45 and finger 44 because of the frictional engagement between the two said parts, but the desired position for the said finger and plate is a forward position when the slide is brought around to the first position in the machine, z'. e., the position in which it is ready to receive a cake from the feeding nozzle. For the purpose of moving the said plate and finger forward, I have provided a stationary cam piece 205 which is adapted to engage the abutment 46 upon the lower face of the said plate 45 after the plate and slide have left the fourth position and before they again reach the first position.

In order to prevent the slides from moving radially in any positions other than the first and fourth positions, I have provided a stationary ring 206 which is received between the abutments 86 and S7 upon Jthe slides in all positions except the first and fourth. The said stationary ring is cut away as is shown at 207 and 208, in the part thereof corresponding to the first and fourth positions, but while the slides are in these cut-away positions they are positively held by the

studs

88 and 202 so that other than predetermined movements thereof are prevented. It will follow from the foregoing that as the slides successively reach their first position they will have been brought to a proper position to receive material fed thereto from the feeding nozzle.

It is, of course, understood that a complete cycle of the machine is effected during each one-sixth of a revolution of the carrier plus the time the carrier is at rest at each point, or in other words, that in the present machine wherein the carrier has siX receivers, six cycles are completed in a complete revolution of the turn table. The

folding, labeling, and discharging operations at the different points in the machine are carried on simultaneously upon successively formed cakes, as will be well understood.

From the foregoing it will be seen that a predetermined quantity of plastic material measured by the material itself will be forced through the nozzle during a feeding operation, and that during such time all the rest of the machine will be idle. Immediately the feeding mechanism is stopped the segregating mechanism comes into operation to segregate a portion of the material so fed forward, and various operations upon previously segregated sections of material will be carried out in various parts of the machine. The carrier will then be given a step by step movement to its neXt position, the train of mechanism governing the movements of all but the feeding mechanism being brought to rest upon the completion of the movement of the turn table, and the feeding mechanism again started into active operation.
