WRAPPER-CUTTING AND REGISTERING APPARATUS..

. Specification of Letters Patent.

' Patented May 21, 1907.

Original application filed April 3, 1905, Serial No. 253,517. Divided and this application filed November 16, 1905.

- Serial No. 287.744- 1 To all whom itmwy concern:

' Be it known that I, Janus HENRY BRADY, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Mapper-(Puttmg and Registering Apparatus, of which the following is a specification.

This invention relates to means for cutting.

printed wrappers from a web used in wrap ping i'nachincs and registering the printed label portion upon the article wrapped therein. l The web is severed while in motion by 'cutting devices whose operation is controlled in the accompanying drawings is one which experience has demonstrated to be practical and efficient but changes in the details of structure and arrangement may, no doubt,-

be devised by those skilled in such matters without departing from the principles of the invention. Figure 1 is a longitudinal sectional diagrammatic view; Fig. 2, a transverse detail section-showing the web severing cutter and its trigger; Fig. 3, a bottom plan view showing electrical contacts that control an electric circuit that determines the moment of actuation of the cutter; Fig. 4, a longitudi- .nal detail section, on a larger scale than Fig. 1, showing the electrical contact devices; Fig. 5, Fig. 6, an enlarged detail view of the electric contact devices.

2, indicates a horizontal base plate upon which-is mounted a reciprocal carriage 3, by means of guide-shoes 51 grooved to receive the edges of tho-plate 2. y The side bars of carriage 3 are rigidly connected at each end by cross-piece ll. The rightdnind end of Fig. l is regarded as the front of the machine for the purpose of thisdescription.

The figures in the drawings illustrate my invention as embodied in. a machine for wrapping cakes of chewinggum, a full description of which will be found in the application above referred to.

To the rear cross-piece 14; is secured a a plan view'of the label web and cake-ejecting bar 15, adapted to push the bottom cake from a stationary hopper 50. When carriage 3 moves forward bar 15 pushes the bottom cake in hopper 50 forward under

springs

55 and 56 until the rear edge of the cake drops in'front of a shoulder formed by an abutment plate 17 attached to the base plate and constituting the bottom of the ho ppel, V

9 represents a web of waxed paper, and S a printed label web, which are together drawn forward, one superimposed upon the other, under the base-plate, through the contact devices, and upward through a diagonal slot 65, in the base-plate upon the upper face of which they lie. In the base-plate in front of

springs

55 and 56, is a spring 57, acting to. elevate the free ends of webs 8 and 9-. When the lowest article or cake in the hopper is pushed forward, springs 55 and 56 press it upon the web, the end of which, extending beyond it, is slightly elevated by spring 57 (Fig. 1).

The laliel web 8 is formed with openings, or breaks in its uniform continuity,'shown, in.this instance, as perforations 64 ,(or'slits 19 and 10) (Fig. 5), arranged mid-way between the printed labels. If a slit like that illustrated at 10 is used, the transverse out thereof is preferably disposed centrally between the labels. The exact location of the openings in the web depends upon the adjustment of the devices.

Y Electriccontact devices (Figs. 1, 3,4,5) are secured to the under face of the base plate. The. waxed web 9 (Fig. 4) passes above, and the perforated label web 8 below, a separating plate. An insulated contact spring 61, provided with an upturned 'tacts 5?) and 60, until spring 61, enters a perforation or slit, and so lifts contact piece 59 against contact 60 closing an electric circuit.

A wrapper-folding shoe 18, having apresser spring 68, in front and an auxiliary presser spring 69, is ca led at the rear end of a shoearm 16, secured to and reci roosting with the front cross-piece is (not illustrated) oi oarriege 3. in the basc-plate eshort distance in front oi spring 57, there is e slot 66 adapted to receive the cutting edges of a cutter 67, pivoted on a shaft 1. on one side of base-plate 2, and urged downward by e strong spring 6. Just above the cutter is a trigger 12, (having it spring 4 applied to it) pivoted on a stud 13, and having oneend notched to hold the free end of the'cutter, end its opposite end provided with anermeture for anelectro mag: net 1. A cord passingover a guide ullcy and through the eye of c link csrrie by a stand ard 5 on theba-ss plate has one end attached to cutter 67 near itsnpper edge, and its other end to the carriage 3; The cord is of suchlength en so arranged that it raises cutter 67, at the end of the forward stroke of carriage 3, a suliicient height to be engaged by the spring latch or trigger 12, in which position it is held by the trigger during the rear ward stroke of carriage 3 and a portion of the forward stroke. When the point of s ring 61 passes int-'0 a perforation in the lobe -web the circuit of magnet l is closed at contact pieces 59 end 60 and the armature carried by the trigger being attgectcd the cutter is re. leased. 'lhc'cuttcrb? being held in elevated position during the rearward stroke of shoe 18, allows the shoe to pass freely over slot 68 toward hopper 50. A cake of gum or other article to be wrapped having been fed by plunger 15, upon the web and under

springs

55 and 56 shoe 18, as it moves to the rear, strikes the tree ends of

webs

8 and 9 which are held up by spring 57, folds them' around the forward edge and down on top iof the cake where theyare held by spring 68. The shoe I travels over the cake until its heelor lower cake. 'As shoe 18 moves forward it drags with been turned over it and that are clamped by of the it the cake together with the webs that have spring 68. During this forward trevc webs, a perforation in the label web is brougl t opposite the poinflof Spllbgf 61, the contact pieces come together, magnet 1 is energized and cutter 67 is instantly thrown down by its spring, the webs being severed at the proper point, i. (a, midway between the lacls. To facilitate assembling the contact apparatus is made udjustabllongitudinally oi the base plate. The mac line can not get out of time, so to out the wrapper across the label or fail to ragister the printed label portion properly on the coke, because cutter 67 willonl y descend when the pol nt of spring segues 61 meets a perforation, and when a perforation is over slot 66. The cutter may be of I any appropriate character. As shown its edge is serrated, as also are the edges ol the slot 66. The term perforations (referring to the web) as used in the claims is intended to include equivalent apertures, slits, notches or other breaks in the continuity of the sur face of the web. The web severing means controlled by such perforations are shown as electrical and are preferred for the reason that not only instantaneous action of the cutter is eilected, but the part controlled by the perforations may be very light, have but slight pressure upon the web and small extent cl movement.

In order to prevent the webs from being carried forward out of position when a take of gum is ushed out upon them, 'a stop 63 working t rough an aperture on the base late is mounted on a spring and adapted to be depressed by plunger l5 and hold the waxed web 9 firmly while tho mike is being pushed thereon.

It is unnecessary to describe or'show the remaining operations for folding the wrapper over the article and discharging the wrapped package from the machine.

The electric circuit may be arranged in any appropriate way. As indicated spring 61, carrying contact piece 59, is insulated, and contact 60 is in electrical connection. with the frame? Consequently one terminal of the magnet-coil should be connected to spring 61 and the other should be connected to an insulated pieoewith which some moving part of the frame contacts at such times as energization of the magnet is required.

I have shown in Fig. 1 part of the folding devices ldescribed and claimed in my epplicetion Serial Number 253,517, liled April 3rd, 1905. Such folding devices form no part of the invention lierein claimcd and have been shown in the drawing merely to illustrate one way in which the paper web, or webs, may be drawn forward. v
