Application filed August 1, 1919. Serial No. 314,592.
To all whom it may concern:
e it known that I, HARRY L. JOHNSON, a citizen of the United States residin at Boston, county of Suffolk, stiitefif assachus setts. have invented an Improvement in Wrapping Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.
This invention relates to wrapping machines of that type which are adapted to wrap a sheet of paper about a package, and, if the Wrapping paper is a wax paper, to seal wrapped package by softening or melt- 15 ing the wax on the paper at the places where it is folded so as to Cause the folded edges to adhere together.
The objects of my invention are to provide an improved machine of this type M which has various novel features, all as will be more fully hereinafter set forth.
In order to give an understanding of my invention, I have illustrated in the drawin s a selected'embodiment thereof which W111 6 now be described, after which the novel features will be pointed out in the appended i-laims.

Fig. 54 shows the arrangement of shafting for driving the different parts of the machine. a
The complete machine herein illustrated comprises a feeding-in belt by which the packages are fed into the machine, a transferring plunger for transferring the packages singly from the feeding-1n belt to a feed plunger, said feed plunger which elevates the packages through an opening in the bed of the machine, paper-feeding devices which feed sheets of wax paper over the feed plunger and beneath the opening in said frame so that when the feed plunger raises the package through the opening the sheet of wax paper is carried up through the opening with the package, and during its operation is wrapped about three s des of the package by the sides of the opening, folding instrumentalities which fold the edges of the paper about the bottom ofthe package and also fold the ends of the paper about the ends of the package, and a heater which heats the folded portions of the paper sufficiently to soften the wax thereon so as to seal the package.
The operative parts of the machine are carried by a suitable framework indicated generally at 1. The feeding-in belt which into the machine is feeds the packages p two diindicated at 2, and it passes around rection pulleys 3 and 4 and has at each side thereof guide members 5 between which the packages 7) are carried by the belt. The belt may be driven in any suitable way, but I have herein shown the pulley 4 as positively driven from a sprocket chain 6 which passes around a sprocket wheel rigid with the pulley 4 and which is actuated by a sprocket wheel on a driving shaft 7 that extends longitudinallv of the frame. Said shaft 7 is shown as being driven from a driving pulley 8 carried by a shaft 900 that is geared by means of gears 920 to a shaft 921 that has a bevel gear 901 thereon meshing with a bevel gear 902 on the shaft 7.
Situated at the inner end of the feedin in belt is a transferring plunger 10 whic moves transversely of the belt and by its movement transfers the end package p on the belt from the belt to the feed M? 11 which has a vertical movement. he transferring plunger 10 has the front vertical face 10 which acts against the package to push it from the feeding-in belt 2 onto the feed plunger, and the side face 10" which is situated over the belt when the plunger is in the forward position shown in Fig. 45 and in dotted lines Fig. 5. side face 1O acts as a stop for the ackages p on the feeding-in belt and hol s the package in position until the transferring, plunger is withdrawn. When said transferring plun er is in its retracted position shown by fu 1 lines, Fig. 5, then the packages on the belt 2 will be fed forward until the foremost package strikes the stop 9. This stop properly positions the foremost package so that on the next forward move ment of the transferring plunger said foremost package will be pushed from the feeding-in belt onto the vertically-moving feed plunger 11.
Situated between the feeding-in belt 2 and the.plunger 11 is a supportin platform 360 which partially supports t e package 7) when it is in position on the feed plunger. In passing onto the feed plunger the package is pushed through an opening 361 (see Fig. 44) between the stop plate 9 and a guide plate 362, said opening constituting a sort of guide opening for the packages as they are delivered to the plunger.
The transferring plunger 10 is carried by a slide 12 which is provided with guiding cars 13 that embrace and are guided by a guide-plate 14 (see Figs. 5 and 6) carried by the frame, and said slide is actuated from a cam groove 15 formed in a cam 16 fast on a shaft 17 forming an element of the papersupply device, as will be presently described. The cam groove 15 receives a stud 18 carried by a lever 19 pivoted to the frame at 20 and connected by a link 21 with an elbowlever 22 pivoted to the frame at 23. This elbow-lever is connected by another link 24 to the slide 12 so that at every revolution of the shaft 17 the transferring plunger will be given a complete forward and backward reciprocation. It will be noted that this transferring plunger is actuated from the shaft 17 forming part of the paper-supplying means, and hence will only be actuated as the paper-supplying means is operating. The purpose of this will be presently des ribed.
As stated above, the transferring plunger 10 in moving from the full to the dotted line position. Fig. 5, carries a package 71 from the belt 2 onto the feed plunger 11.
This feed plunger and belt are situated be- This neath the bed of the machine which comprises the lower plate havin an opening 26 therein and an upper late 2 also having an opening 28 therein. he upward movement of the feedplunger 11 carries the package upwardly through the openings 26, 28 into a position above the upper plate 27, and as each package is thus elevated through the openings 26,28, 1t 1s taken by the conveyor and carried to the end folders,
, package.
29 indicate rolls placed at opposite edges of the opening and spaced apart a distance equal to the width of the package so that as the package with its wrapping paper w is forced up through the opening 28, the rolls 29 will engage the sides of the package and hold the paper in close contact therewith, thus folding the paper about three sides of the package.
The feed plunger 11 is herein shown as guided in its reciprocations by a guiding member 30'and as being connected by a link 31 to an arm 32 fast on a rock-shaft 33 which extends transversely of the frame, said rockshaft having another arm 34 fast thereon which is connected by a link 35 to a lever 36 pivoted to the frame at 37 and having a projection or roll which is received in a cam groove 38 in a cam member 39 carried by the shaft 40, see Fig. 2. Said shaft 40 extends transversely of the frame 1 and is geared to the shaft 7 by suitable bevel gears 41 (see Fig. 54). The elevating plunger will thus be reciprocatin in a vertical direction so long as the sha t 7 is operating.
After each package has been raised into the position shown in Fig. 51 thereby to wrap the sheet of paper w around three sides of the package, the edge 42 of the paper w is folded underneath the bottom of the package b means of an edge folder 43. This edge older is in the form of a plate which is mounted on the frame for horizontal movement, and it is actuated in proper timed relation with the other parts of the machine so that after the package is raised into the position shown in Fig. 51, the folder 43 moves forwardly, and in doing so forces the edge 42 of paper beneath the package, as shown in Fi. 52. This edge folder is illustrated in Figs. 3, 48 and 49, and it is actuated from a cam member 44 fast on theshaft 40. For this purpose said folder is connected by a link 45 to a lever 46 pivoted to the frame at 47 and connected in turn by a link 48 to a lever 49 having a projection entering a cam groove 50 in the cam 44. The edge folder-43 is guided in its reciprocations by a guide member 703. The lever 46 is provided with a plurality of holes for receiving the pivot 47 so that by shifting the lever into different positions relative to the pivot, the extent of movementof the ed e folder 43 can be varied. This provides or operating on packages of different sizes.
Situated at the rear of the openin 28 above the bed 27 and at the opposite side of said opening from the edge folder 43 are two guide fingers 51, see Figs. 4, 48 and 49, which are fast on a rock-shaft 52, said rockshaft having an arm 53 fast thereon to which. is connected a ullin spring 54. Said arm 53 is also provi ed wit a pin 55 adapted to be received in a notch formed in a lockin latch 56 pivoted at 57 to the frame. Said %ocking latch normally holds the fingers 51 in their elevated position so that when the packa e is elevated through the opening 28, sai ffiigers will press against the back side of the package and will hold the wrapping paper w firmly in contact with the package.
Afterthe edge, 42 of wrapping paper has been folded underneath the package, as shown in Fig. 52, the package is then engaged by the conveyor, presently to be described, and moved over the bed plate 27. Means are provided whereby the guide fingers 51 are unlocked just before the package is carried backwardly onto the bed 27 by the conveyor, and in the construction shown, this unlocking of thu fingers is accomplished by the folding movement of the edge folder 43. Said folder 43 is provided with an arm 58 having a cam or beveled surface 59 thereon, and as the folder is given its folding movement the cam surface 59 of said arm passes u'ndera roll 60 carried by the locking latch 56 and raises said latch sufficiently to disengage it from the pin 55. This unlocks the fingers 51 so that when the ackage p is carried onto the bed plate 27 y the conveyor,-said fingers can swing downwardly into a horizontal position to allow the pack ages to pass over them. During this movement of the package the edge 61 of the paper' is folded underneath the package, as shown in Fig, 53, by the edge of the opening 28, the yielding'pressure of the fingers 51 against the bottom of the package assisting in this folding operation. As soon as the package has passed over the fingers 51, the spring 54 returns them to their uprightposition where they become automatically locked by the latch 56.
At this stage of the operations the wrapping paper is wrapped about thefour sides
