I Specification of Letters Patent.

Patented Mar. 4, 1913.

To all whom it may concern:

Be it known that I, JAMES A. KEYEs, a citizen of the United States, and resident of the city, county, and State of New York, have made certain new and useful Inventions Relating to Wrapping-Machines, of which the following-is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates to wrap ing machines and relates especially to .mac ines for wrapping cakes of soft or weak material such as compressed .yeast and the like, although. of course, these machines may be used for wrapping other articles.

In the accompanying drawings showing in a somewhat diagrammatic way, an illustrative embodiment of the invention, Figure 1 is a side elevation with the adjacent frame member removed, Fig. 2 is a similar view from the other side of the machine, Fig. 3

is an end view' looking from the left in Fig.

1, Fig.4 is the opposite end elevation, Fig. 5 is an enlarged sectional view of the paper feed rolls, Figs. 6, 7 and 8 are enlarged detail views of the lifter devices, Fig. 9 is a top view showing the folding devices, Fig. 10 is an enlarged vertical. sectional view of the folding plunger and associated devices, Fig. '11 is a horizontal section thereof along the lines 111l of Fig. 10, Figs. 12 and 13 are enlarged transverse showing progressive folding operations,

Figs. 1-1and15 are similar side elevations,

Fig. 16 is a detail view taken at right angles showing this end folder, and Fig. 17 is a perspective view showing the wrapped cake.

In the illustrative embodiment of this invention shown in the drawings one or more wrappers of paper or the like, may be used to inclose the cake of yeast or other article and they may be in the form of continuous webs 1, 2, the inner web 2 being of waxed paper or the like if desired, and the outer wrapper strip or web 1 being if desired, printed with suitable advertising matter and also perforated with alining apertures such as 231 indicated in Fig. 5 to regulateits alinement. The inner wrapper 2 may pass over the guide roll- 4 in the bearin brackets '3 and over the similarly a justable guide roll 12 in the bearings lland then this inner wrapper may pass over the guide 13 provided if desired, with the frictional gripping finger 14 indicated in Figs.

- .of the roll to the desired extent.

sectional views i 4 and 5, in order to maintain the proper tension in the web and prevent its moving backward when released. The outer or printed wrapper 1 may pass over the similar guide roll 5 in the .bearin brackets 6 supported on the extensions 7 and then over another guide roll 8 in the adjustable bearings 9 before passing over the feed board 16 and into the bite of the feeding and

cutting rolls

19, 20, indicated in Fig. 5.

The knife roll 19 on the shaft 17 65 may be provided with the transverse knife or cutter 25 mounted in suitable yielding material so that its edge projects from the 'periphery' The 00- operating roll may have a recessed block of wood 26 to cooperate with the knife and may be rotated by its shaft 18 ill-111115011 with the cutting roll so asto feed the paper strips between them and severthem at the proper time. In order to allow strips of different length to be used in the machine it is desirable to form the knife 'roll with a fiat releasing portion or face'23 on its periphery so that when this portion 23 comes into engagement with the opposing roll the wrapper strips are not gripped but may be longitudinally adjusted to the desired extent. A suitable friction retarding device may .be used in connection with the outer wrapper strip and the frictional gripper 32 may be faced with rubber or other material to engage the wrapper with the desired effectiveness. This gripper may be mounted on the rock arm 31 connected by the link with the rock lever 29 and the link 28 connected with this rock lever may carry at its lower portion, the cam roll 27, cooperating with the cam 24 on the shaft of thecut-ter roll so that the gripper 32 is nor- 95 mally held in the raised inoperative position shown but after the wrappers have been severed this gripper is released to engage the wrapper strip. From the rolls the wrapper strips pass through the curved 0 guides 33 so as to be engaged by the gripper 36, which serves to aline the wrapper when the cylindrical paper aliner 254 is engaged by the remaining half of the circular perforation 231 in the end of the wrapper strip. The gripper, after it has moved up and engaged the end of the wrapper strips, may then if desired, definitely aline them by pushing the wrapper back through the feeding rolls which are then in their released that a greater length of wrapper may be withdrawn. and the gripper, instead of forcing the wrapper back into alinement after first engaging it, may withdraw a suitable additional length at any time in the travel of the gripper when the feed rolls are in disengaged position.

The heavy frame of the machine may be made of suitable side members such as 83 and 84 connected by suitable rigid braces and this frame may carry the supporting bracket 85 on which the

paper feed plates

10, 15, may be mounted. The driving shaft 48 may be mounted-in the machine frame in any desired way and may be operated by the pulley 222 or otherwise and may be turned over for adjustment by the hand wheel 221. This drive shaft may carry the gear 47 meshing with the idler gear 46 on the shaft 49, which also meshes with the gear 45 on the paper feeding shaft 444 The shaft 50 also carries a similar idler 51 meshing with the gear 47 and also meshing with the gear 52 on the cam shaft 55 so that all these shafts are operated in unison. The sprocket .225 on the paper feed shaft 44 operates a suitable sprocket chain 223 which engages the sprocket wheel 224 on the shaft 17 of the cutting roll, see Figs. 2 and 3. The shaft 18 of the cotiperating feeding roll is driven by the meshing gears 228, 229 on these two shafts. The gripper 36 may, as

indicated in Fig. 1, be mounted in a suitable slide 219 in the frame and may be operated by the link 38 through a stud 37 and pivoted at one end of the gripper lever 40 by a bolt 39 and which, as indicated in Fig. 2, oscillates about its pin 42. This gripper lever carries the cam roll 41 meshing with a suitable inclosed cam groove in the cam 43 on the shaft 44. The movable gripper jaw 256 is pivoted about the pin 218 shown in Figs. 12 and 13 and is normally swung toward the opposing stationary gripper jaw 36 by a suitable light spring 255. A suitable releaser 172 may be used to control the position of the movable gripper jaw and this releaser may be slidingly mounted in the guide 173 on the gripper slide 219. As long as the releaser is in the osition shown in Fig. 12, it forces the tail 175 of the gri per jaw into such position. as to swing t e connected movable gripper jaw 256 away from the cooperating jaw" 36. As the gripper moves upward the releaser-172 engages the adjustable gripping stop 170 on the the feed raiser 73 may operate. as is. indicated in Fig. 2, may be provided slideway 220 and wedges this releaser downward into its ide so as to force itout of engagement with the gripper tail 175, thus allowing the gripper jaws to engage the wrappers. As the gripper. is drawn downward together with the wrappers the releaser 172 finally comes into engagement with the adjustable releasing stop 171 so as to wedge the releaser up into engagement with the gripper tail 175 opening the grip- .per jaws and releasing the wrappers. The

lower ends of the wrappers are thus left resting in the notches 253 of the adjustable paper stops 174' shown in detail in Fig. 13.

The cakes of material such as the large cakes of compressed yeast used by bakers require careful handling and for this reason it is desirable to have a readily controlled feeding device which may be of the fourmotion type indicated in the drawings. The feed bracket 76 may be formed of two outer plates as indicated in Fig. 4, between which This raiser with two or more inclined cam portions which coiiperate with similarly inclined sta- V tionary raising cams 74 on the bracket. The feed raiser is thus vertically raised as it is longitudinally reciprocated by any desired means, such as by the link 78 engaging the pin 75 on the raiser connected at its other end with the raiser lever 79 which is pivoted about the pin 82 as shown in Fig. 1. The follower 80 on this lever engages the closed cam groove9l in the raising cam 81 on the shaft 55 so as to reciprocate this feed raiser at the proper time and cause a slight vertical movement of the raiser'and the heavy plate feeder 71 supported thereby and guided laterally between the plates 76. This feeder may be reciprocated by a feed rod 61 pivotally or otherwise removably. secured to the pin 69 in the bracket 70 on this feeder and having its other end loosely hooked over the crank and pin 60 mounted upon the aliner rod 59, as shown in Fig. 2. The operating arm 58 of this crank may be connected by the link 57 with a suitable yoke passing over the shaft 55 and supporting the follower 56 so that it cooperates with the closed cam groove 54 in the cam 53 so that the raiser is first raised slightly, carrying the feeder -71 and the cakes 72 clear of the feed table 257' and then the feeder is moved forward about the width of a cake before the raiser again lowers, leaving the cakes supported at either side of the table. It is desirable in feeding such friable material to have a safety device on the feeder to prevent over feeding and possible crushing of the articles;

This may be conveniently effected by having a suitable relief connection in the feed rod 61 by securing the guide 62 on one end of the rod and interposing a suitable spring 67 between the pin 63 on this guide and the omo-re pin 68 on the end of the other'section of the feed rod. This limits the feeding pressure and a further desirable .safety device may consist of the yielding aliner 108 in the path of the cakes as indicated in Figs.*6'to 8,

This aliner is mounted on the aliner rod 59 supported in suitable brackets mounted upon the frame 84 and the aliner may be normally held improper position by the alining spring 120 which allows the aliner to yield in case of excessive'pressure of the cakes thereon so as to minimize breakage. The stop pin 114 is supported in the

bracket

112, 113, inthe frame and its head 118 is normally down out of the path of the feeder stop"119 on the feeder 71, as shown'in .Fig. 7. If, however, thealiner is tilted by excessivepressure of the cakes the collar 116- is correspondingly raised so as to exert through the, spring 115 suflicient pressure on the'stop pinthe end of the feeder by a suitable lifterwhich as" indicated in Figs. 7 and 8 ma comprise the two lifter members 123-on eac side of the feeder 71 and having curved arms 122 to avoid interference with the aliner rod and supportedon thelifterslide 124 guided in the ways 121 asshow'n in ig. 7. This lifter slidesmay' be recipjrocated by the link 136 connected to the pin 137 in the slide and pivoted at its lower-end to the free end of the lifter lever 182 which is mounted on its pin- 185. ,This'lifter lever carries the follower 1'76 coiiperating with a suitable cam groove in the cam 230-01; the

shaft 55 as shown in Figs. 1-a'nd4; It is also desirable to have a-suit'able disengager to'positively disengage the aliner from. the forward cake beforethe lifter'members v123 on each side of the feeder" raise the-cake therefrom.- This may- ;convenien'tly effected by providing-"the adjustabledi'sem gager -110 on they top of the lifter slide so that it engages the aliner tail 111-s'o as to the first cake before itis raised int-o the upper position shown in Fig. 12, where it is engaged and forced forward by the printing plunger. 93 having the head 95. This printing plunger 93 may be mounted o'n'the slide .and reeiprocated at the proper time by the suitable link 89 connecting thisslide to the u )per mid of the plunger lever 88 as shown in Fig. 1. This plunger lever may be pivoted about the pin82 and carry the follower 87 cooperating with a suitable closed cam groove in the cam 86 on the shaft 55 as shown in Fig. 4 so as to force the cake forward, carrying therewith the .rearplath slide 208 may be mounted in the ollower 212' cooperating with the cam the a-liner out of engagement with. old this brush up in the inoperative posi- -front of the p 'rear'. platen '207 on the slide 208 so as to move gradually back behind the cake in with the printingplunger to' insure thejproper' .printing action thereof. This the guideway 209 shown in Figs. 1 3 and 1 2 and reciprocated at the proper time by the connecting link 210 and the platen lever 211 ivoted about the pin 198 and having groove in the cam 213.

It is desirablevwith such soft friable Jmaterial as yeast to insure the propercleaning of the printing head or die after each im-f pressionand for this purpose a. suitable- 5::-

cleaning brush maybe mounted to cooper 'ate with the printing plunger as shown in Figs. 6 to 18. This brush 97 may bemounted in the vertically moving brush frame 98}..-

guided on the pins 99, 103', in the-bracket 100; On the hollow stub-shaft 2660f this brush a suitable brush pinion 102 may be mounted so as to cooperate with the stationary. 'brush rack 101 and rotate the brush asit is raised and lowered. ,It is also desirable 1 a) change the angular position'of this brush from time to time and this may be conveniently effected by providing a series of angula-rly spaced slots. 104 in the hollow brush shaft 266 and havin a pin 267 on- 'the relatively movable br'us stem '268 so that by withdrawing this brush stem against the pressure of the spring 105 by takin hold' of the head 265 the pin267 may he s ip (1 into another of these notches. This brus 1 automatically raised by the lifter so asto be keptoutof contact with the cakes andthis may be etf ected by providing the lifter pin 107 so as to coiiperate with the "bracket 96 on -the brush. frame and thus carr the I brush; upward as the lifter is raised. hen,' as the printingplun er/93 moves forward the guide 94; on the s de of this plunger, as shown in Fig. 6, moves forward under thefiuide lug 250 on the brush frameso' as to tic-n shown until the plun er again withdraws, whereu on the brus falls down in lilnger face so as to clean it, 7 the fall being cushioned by springs such as 106 on the guide rod 99.

-- As the cake72 is forced by the printing plunger between the stationary folding bars and'-126, the wrappers'a're thereby 'fold- 811*81011I1d the cake so asito .inclose it on 126 three sides by the time the cake comes into pdsition above. the folding plunger 139. The lower side folder 164 on this plunger then moves upward forming the lower side fold and then the plunger moves bodily up- 130 p position indicated.

ward, carrying with it the cakeiand forming the upper side fold as the wrapper engages the rubber grippers 206 on .the discharger. cated in Figs. 10 and 11, is vertically guided from a suitable bracket 138 which carries the dovetail guide 163 fitting in the plunger as is shown in Fig. 11. The plunger itself is vertically reciprocated by the bar 150 carrying the cam roll 154 fitting in the closed cam groove 149 of the cam 147 on the shaft 48. The lower side folder 164 is pivoted on the folder slide 141 mounted in a suitable guideway 142 in the plunger, see Figs. 11 and 12, so as to be vertically recip'rocated by the bar 143 carryin the cam roll 144 cooperating with the cfosed cam groove 148 in the cam 145. This side folder is normally pressed inward in line with the plunger by a suitable spring 167, but the relatively movable cam 166 secured to the plunger holds this folder out in the inoperative position shown in Fig. 12 when it is in its lowered In this way as this folder is moved upward it enga es the lower lap of thewrappers some little istanc'e away from the cake so as to more readily fold the wrappers around it and then when the folder has moved out of engagementwith the cam, as shown in Fig. 13, this folder snaps in into close engagement'with the cake so as to hold the wrapper tightly against the same. When this has occurred the folding plunger 139 moves upward, carrying with it the cake and wrappers which are frict-ionally engaged by the pivoted grippers 206 faced with rubber or similar material and having their supports 204 pivoted about the pin 205 in the dlscharger arm 203. This additional frictional engagement on the free end of the wrapper folds it .tightly around the-cake so as to take up any slack, which is also assisted by the top platens 179 which finally come into engagement with the top of the cake. These top plates may be supported on the-platen rods 180 in suitable guide brackets so that the weight of these platens and rods brings them into engagement with the upper portion of the-wrapper soas to holdthe same down firmly against the cake and assist the positioning At this time the

rear end folders

185, 186, are swung around into engagement with the wrapper ends to make the first end folds therein. These end folders are pivoted in

suitable brackets

191, 192, supported from the stationary folding bar 126 and the folders carry at their upper ends the geared folder sectors 187, 188, meshing with the folder racks 189 on the r-ack slide 190, see Figs. 9 and 15. As is seen in Fig. 1, this rackslide 190 is secured to the plunger 193 which is reciprocated by the link 194 and rack lever 195pivoted about the pin 198. This rack This folding plunger, as is indi lever carries the follower 196 engaging a suitableclosed cam groove in the cam 197 on the shaft 44 as shown in Fig. 3. When these rear end folders have operated the

bottom end folders

158, 159, are actuated by the support 156 and slide 155 and connected roll 153, shown in Fig. 10, as coiiperating with the groove 152 in the cam 151. This forces these

folders

158, 159 upward so as to en gage the overlapping wrapper ends at some distance from the cake and then, after having partly formed the fold the ends 162 of these pivoted folders move out from under the

stationary cams

160, 161 on the folding plungers so that the folders snap down into firm engagement with the cake and set the folds. The

top end folders

177, 178, then operate to form the top end folds and close them down into holding engagement with the folds beneath. These folders are pivotally mounted in the

folder arms

181, 183 on the folder shaft 128 and are provided with suitable light springs 184 normally tending to oscillate these folders in toward the cake. As the folders are brought down toward the cake and wrapper the pins 251 connected with these pivoted folders engage the cams 252 so as to rock the lower edges of the folders out slightly and facilitate starting of the folds. Then, when these pins 251 ride past the lower ends of these cams the springs throw the folders inward against the ends of the cake so as to complete and set the folds. The cam pins 251 on the up.- ward movement of the folders ride against the stationary cam surface 262 and move past the pivoted cams 252 which are normally held in the position indicated in Fig. 16 by the light springs shown. The folder shaft'128 is oscillated at vthe proper time by the arm-129 shown in Fig. 2, connected thereto and pivoted to the cam rod 130 hav- I ing a guide yoke at its lower end to embrace the drive shaft 48 and hold the cam follower 131 in engagement with the cam groove 133 in the cam 134 on this shaft. The discharger plate 204 is then moved forward by the discharger arm 203 shown in Figs. 9 and 12 soas to carry the cake for ward between the stationary end folders to form the final end folds in the wrappers, as is indicated in Fig. 15. This discharger arm is reciprocated by the link 202 pivoted to the discharger lever 201, carrying the cam roll 199 coiiperating with the cam 200 on the shaft 44, as shown in Figs. 1 and 3. The completely wrapped cake 232 shown in Fig. 17, is thus intermittently fed forward along 'the discharge table 216, shown in Fig. 2, be-

tween the side guides 215 which hold the end folds of the wrapper in proper position until the wrapped cakes are taken from this table for packing.
