` To all/whoa?. .it may concern:

Be it known that I, HiLARIo DE EsooBALEs, a citizen of Porto Rico, and a resident of the city of New York in the county of Richmond and' State of 2New York, have invented a certain new and useful Improvement in Wrapping-Machines, of which the following is a specification.

This invention relates tol machines in which an article and a wrapper are passed through folding devices -whereby the wrapper is folded around the article.

The object of the invention'is to provide means whereby the article can' be effectually covered, and to provide means whereby the wrapper can be readily removed.A

The inventionA consists of a movable channel section having inwardly extending side .projections which serve to fold overhanging side portions of a wrapper when an article and a wrapper are moved into the channel section. p

The inventionalso1V consists in means whereby the channel section is intermittently rotated, and mechanism operated by said means for intermittently rotating the channel section,l whereby apaper sheetand a strip of tape can be moved into pos1t1on to be forced into the channel section after its rotary movement ceases.

The invention further consists in the use of a stationary wrapper folding channel having inwardly extending side projections which serve to fold overhanging side portio-ns of the wrapper, which overhanging side portions are caused by said rotary move-` ment of the channel section.

In the accompanying drawings: Figure 1 is a sectional elevation taken on the line I-I of Fig. 2. Fig. 2 is a horizontal section on the line II-II of Figfl. Fig. 3 is a perspective View of the Wrapper and tape partially folded upon an article. Fig. 4 1s a perspective view of said article, wrapper and tape when turned over, showing the wrapper and tape further folded upon the article, and showing paste applied to a part ofthe wrapper to be folded upon the wrapper folded on the article. Fig. 5 is a sectional elevation taken on lthe line V-V o f Fig. 6. Fig. 6 is a transverse section on the line VI-VI of Fig. 5. Fig. 7 is a perspective view of the article, wrapper andtape when moved from the rotatable channel section into the stationary channel, vshowing the wrapper and. tapefurther folded upon the article. Fig.8 shows the upper side flaps folded down and paste applled to a lower sidel flap. Fig. 9 shows a paste coated lower side flap folded up against a folded upper side flap, and also showsa pasted end of the tape fol ed within the wrapper.

J ournaled in the main frame 1 is a driving shaft 2 to which is secured a wheel 3 having a series of gear teeth 4 and a convex peripheral surface 5 without teth. The

Vgear teeth 4 are adapted for engagement with gear teeth 6 on a wheel 7 which is secured to a vshaft 8. At the end of a half revolution of

wheels

3 and 7, the convex l surface 5 rides in a concave surface 9 formed onwheel 7 ,thereby causing the wheel 7 and shaft 8 to remain stationary during another half revolution of wheel3.

Forming part of shaft 8 is a channel 'section 10 extending transversely to the shaft and provided with upper and lower plates 11, and. projections 12 extending inward from the two sides thereof. Located between said upper and lower plates and'said inwardly extending side projections is a short plunger 13 adapted for sliding movement in the channel section.

Secured to shaft 8 is a gear wheel 14 in mesh with a gear wheel 15 lwhich is loosely mounted on a shaft 16. Securedl to shaft 16 is a gear wheel 17 in mesh with an intermediate gear wheel 18 which is in mesh with and driven by a gear wheel 19 secured to 16 is a wheel 20provided with a cam groove 21 in which a roller 22 on an arm 23 travels. Arm 23 is secured to a rock-shaft 24 hav ing arms 25 secured thereto. Journaled in the free ends of arms 25 is a shaft 26 provided with a friction wheel 27 at the center and a rollei 28 near each end thereof.As shown in Fig. 5, the cam wheel is causing the friction wheelt27 to be moved toward a friction wheel 29 and .is moving rollers 28 toward rollers 30 which travel in contact with paste 3 1 in receptacle 32. .Friction wheel 29 and rollers 30 are secured to a shaft 33 to which is secured a gear Wheel 34 meshing with and driven by gear wheel 15. Secured to shaft 33 is a gear wheelv 35 in mesh i with a gear wheel 36 which is secured to a shaft 37. v Secured to shaft 37 is a roller 38,

rotruding unthe driving'shaft 2. Also secured to shaft which is secured to a shaft 46.

47 and the strip of tape 49.

roller 48 issecured to a shaft5 to which is lsecured a' gear wheel'51 meshingwith and driven by a gear wheel 52 secured to shaft 46.

After the gear wheel 7 has made a halfl revolution the channel section 9,- the paste applying rollers 28, the'papersheet 40, and the strip of tape 49, will have been moved from the.position shown in Fig. 5

y and lwhich is free to the position shown in Fig. 1. The knife 53 will have cut the tape and paper sheet when the feed rollers have ceased to move, and the tape and paper sheet then fall to the

supports

54 and 55. Cutting of the tape and paper sheet is effected by means l of the movable knife blade 53 coperating with the stationary knife blade .56. The movable blade 53 is attached to an arm 57 which is secured to a vertical shaft 58 to which an arm 59 carrying a roller 60 is secured. Roller 60 engages a cam 6l secured to the driving lshaft 2, which cam serves to actuate the knifev 53.

Secured to the driving shaft 2 is a cam 62 which is engaged by a roller 63 on a lever l 64 pivotedat 65.

The free end of lever 64 is connected by a link 66 to a plunger 67 to slide in guides 68. When plunger 67 is moved to the position shown by dotted lines in Fig. 6, an article 69 falls to rest in front of the plunger. Forward movement of the plunger then causes the article to be moved to rest in front of a plunger 70, as shown in -Figs V1 and 2. Plunger 70 is free to slide in guides 71 and is connected by a lever 73 pivoted at 74. Lever 73 is connected by a link 75 to a crank arm 76 secured to the driving shaft 2, so that rotation of the shaftcauses reciprocating movement of the plunger 7 O;

Forward movement of plunger 70 causes the article 69 to be moved against the tape wrapper, further movement of the plunger then causing the article, tape and wrapper to be moved into the channel section 10. Movement of the article and wrapper into the channel section causes the short plunger 13 tobe moved along the channel section to the position show'n in Fig. 5. During this movement the wrapper and tape take against the upper and lower plates and overhanging side portions of the wrapper take against the inwardly extending side projections 12 of the channel section, causing the wrapper and tape to be folded in the manner shown in Figs. 3 and 5. During return movement of plunger 70 the channel section links 72 to the free end of the gear teeth 4-on wheel 3 engage the gear i teeth 6 on wheel 7, thereby causing rotary movement of the channel section in the direction indicated by -the arrow. During a lhalf revolution of the channel section the unfolded portion b of the wrapper and tape will strike against a stationary part 77 of the machine, causing saidpart b to be folded in the manner shown in Fig. 4, at which time the cam wheel 20 Will have moved 'the paste applying rollers 28 against the part c of the wrap er as shown in Fig. 1. It will be p seen that this half revolution of has caused the short plunger 13 to again be at the entrance end of the channel section. When another article, tape and wrapper has been moved into the channel section, and caused the short plunger 13 to be moved along the channel section, the movement of said short plunger will causethe article, tape and wrapper first named to be moved out of the channel section. During this movement ofthe first named article, tape and Wrapper, the unfolded part 0 of the Wrapper and tape takes against the stationary part 77, and overhanging side portions d of the wrapper take against projections 78 extending inwardly from a stationary wrapper folding channel 79, causing the lparts c and d to be folded -1n the manner shown in Fig. 7. The paste 31 applied to the part c of the wrapper will cause said part -to be held securely to the previously folded part of the wrapper, thereby holding the unpasted tape having the end e protruding beyond the end of the wrapper.

The stationary wrapper foldi'ng channel 79 is provided with an upper plate 80 having two inclined folders 81 extending downward Ain range with the upper side flaps f of the wrapper, so that as the article and wrapper are moved into the stationary channel, the upper flaps f by taking against the inclined folders 81 will be folded down in the manner shown in Figs. 5 and 8.

By reference to Fig. 1 it will be seen that during the travel of the article and wrapper from the channel section into the stationary channel, the folded parts Z of the wra per will be bearing against the inwardly extending side projections 12, so that there Will be little tendency for the parts d to buckle previous to the time they reach the side projections 78, at which time they will be protected by the flaps 7". g

Secured to the driving shaft 2 is a chain wheel 82 which drives a chain.83 riding over a chain wheel 84 secured to a short shaft 85. Secured to shaft 85 is a gear wheel 86 in mesh with agear wheel 87 which is secured to a shaft 88. Near each end of shaft 88 is secured a roller 89 which travels in contact with paste 9() Traveling in contact with each of the paste coated rollers .89 is a wheel 92, one of said CTE in a receptacle 91.

v article and wrapperare moved farther along is moved into the channel section and the second out, the first will. be moved along the 'stationary` channel, and the 'lower iaps g of the wrapper will travel beneath the wheels 92 receiving paste therefrom as shown in Fig. 8. The lower plate 95 of the 'stationary channel is provided with two inclined folders 96 extending upward inrange with the lower flaps g so that as the the stationary channel, the paste ,coated lower iiaps g by taking against the inclined folders 96 will be folded up against, the folded flaps f, in the manner shown in It will be seen that in the completed package shown in Fig. 9, the protruding end e of the tape can be used for the purpose of tearing the paste secured wrap er, owing to the fact that no paste has to the tape. n
