Fig.12 shows in plan spring Just back of'thepackage-fe'eding chute 2 or fingers or plateswhich act upon the paper at upon the side toward which the packages are the ends of the package to fold it down. Fig. moved from the feed-chute is the vertical 13 is a cross-section of the wrapping-chute paper-chute 12. An extension of this chute and the spring-held plate which engages the is seen in Fig. 3 extending beneath the table I00 50 top of the package. Figs. 14 and 15 are views, or upon the opposite side of the Wrappingrespectively, from above and below, showing chute. The paper out to "proper size is fed into the upper end of the paper-chute by mechanism which will be hereinafter described and drops to the bottom thereof, where when the next package is advanced by the plunger 4 the package will engage the paper approximately at its middle and will carry the paper along into the wrappingchute, thus folding the paper into contact with three sides of the package.

To adjust the paperchute to different lengths of paper, as are required for packages of different size, the lower extension of the chute lying beneath the table is terminated by a movable plate 13, Figs. 3, 7, and 8, which snugly fills the'chute and is supported by threaded rods or bolts 14, Fig. 7, by whichit may be raised or lowered. This plate may, if desired, have projections 15, engaging slots or grooves 16 in the side walls of the chute. As the package is removed fromthe feed-chuteby the plungeritis carried to a point in the wrapping-chute where it lies beneath and is engaged by the spring-pressed plate 17, Fig. 3, which is shown in detail in Fig. 13. The edge of this plate firstengagd by the package is preferably beveled or slightly turned up, so that the package may easily lift it. This plate is held down by springs 18, which surround stems 30, which serve as guides for the plate. One stem, as a central one 31, acts as a stop toprevent the plate from dropping too low, said stem having a collar or nut 31 secured to its upper portion. Located one upon each side of the wrappingchute, where they will engage the projecting portion of the wrapping-paper at the passing of the package, are the two tucking-plates 32. These are mounted upon blocks 33, Fig. 3, which slide in guides lengthwise the wrapping-chute and are moved by links 34, which connect them with a lever 35, which may be of any suitable form. This lever is secured to a shaft 36, which is rocked from one end by means of a crank 37 and link 38, (see Fig. 2,) which connects it with a crank-pin or eccentric 39, carried upon the main shaft 9. The relative movement of these tuckers and the package is so timed that they pass in one direction to fold the paper at the edge of the package covered by the middle of the paper sheet, as at a Fig. 22, and then after these ends of the paper sheet have been folded the tuckers move in the other direction to fold the paper over the other edge of the package 1 at the ends of the sheet, as at a Fig. 24.

The first fold or tuck is caused by moving the package past the tuckers and the second tuck by reciprocating the tuckers while the package is stationary. These successive conditions'of the paper are shown in Figs. 22, 23, and 24. The package when advanced by the plunger 4 is left so that the edge which was engaged by the plunger has just passed the foldingblades 40 and 41, Fig. 3. These blades reciprocate through slots formed, respectively, in the plate 42, forming the top of the wrapping-chute, and in the table. One

plate is placed sufiiciently in advance of the other, so that their edges may pass. These blades are caused to reciprocate, so as to fold down the ends of the wrapper, as at b Fig. 23, before the tuckers 32 return to form the second edge tuck a at the end of the package. The upper plate 40 is carried by an arm or rod 43, Figs. 1 and 6, which is restrained to move vertically by means of a suitable block 44 and a slot in the frame, Fig. 6, and is reciprocated by means of link 45 and crankarm 46 upon the shaft 47, (see Figs. 3 and 6,) said shaft being oscillated by means of an arm 48, Fig.2, which engages a cam 49 upon shaft 50, which shaft is turned from the powershaft 9 by means of double gears 51 and 52. The other blade 41 is reciprocated by direct connection with arm 53, which is loose or pivoted upon shaft 47 and engages cam 54.

After the package has been operated upon by the tuckers and folding- blades 40 and 41 it is advanced along the wrapping-chute by the pressure of the package next following it in the chute. As it advances along the chute the upper and lower side tucks or flaps 0 (9,

Fig. 24, at the ends of the package are turned by suitable folders, the upper by the turningguides 54, which consist of curvedplates projecting downwardly from the plate 42, which forms the top of the wrapping-chute. These turning-guides are so curved as to fold the upper side tuck down against the end of the package. At this point the lower side tucks or flaps still extend horizontally and by the progress of the package are passed beneath two paste-wheels 55, Figs. 3 and 11, one on each side of the package, whereby they are givensuch a coat of paste that when they are folded up against the end of the package they will stick there. The paste is supplied to the wheels 55 by means which will be described later. After passing the pastewheel the lower end tucks or flaps are engaged by the folders 56, which turn these flaps up against the end of the package. In Fig. 3 these are shown as being plates which extend upwardly from the table; but I prefer a construction such as is shown in Fig. 12, in which they consist of long blades or spring-arms 107, which are supported from thetable by one end and are also made adjustable lengthwise the wrapping-chute by slots 108 in the table, within which the securingbolt lies, such adjustment being desirable to accommodate the wrapping of packages of difierent sizes. By this constrnction they are made flexible, so that they willact equally well without adjustment upon packages varying considerably in size. The otherset of folders may be similarly construct ed. After the folding operation has been completed the package remains momentarily between the folding or turning guides 56, and the paste has a chance to set. The package is then discharged upon the delivery-chute 57, which is also preferably provided with side bars or plates 58, which also hold the pasted flap down, so that by the time the package e-has left the delivery-ch11 to the paste has thor j the tops of which turn toward each other and one of which engages the wheels 55. As the paste used is stiff and only a small amount is used at a time, no side wall is needed. The turning of the rollers will tend to force the paste towar'd the central line between the rollers. The frame in which the rollers turn acts as end wallsflhese rollers are turned by means ofha vertical shaft 73 and two sets of bevel-gears 74 and 75, which connect it, re-

spectively, with" the shaft 50 and the shaftof the 'PQllerfiO.

A preferred foriiiof pasting device is shown in Figs. and ll'fiin which but a single-roller is used. 7 This is turned in the same way from the shaft 50 and has a paste box or holder 61 placed upon it. This box is open on its bottom where it engages the roller, either in whole or in part. At the edge from which the paste passes out it is provided with an adjustable scraper or gate 62, by which the thickness of the paste-layer on the roller may be adjusted. p

A single or a double wrapper may be used in my machine. In the drawings I have shown two wrappers, an inner and an outer;

but it is evident that either of these may be omitted. The paper should be in rolls, which would be mounted at any convenient point. The roll from which the paper 76 forming the outer wrapper is drawn is not shown in Fig. 3, but is shown at 63 in Fig. 1. This paper passes first through feed-rollers 64 and then between a pair of idler guide-rollers 66, the paper between these two pairs of rollers hanging in a loop, in which is placed a weighted roller 65, which is suspended by the paper.

The feed rollers 6i are constantly driven.

by means of a shaft 110, Fig. 3, which is connected by bevel-gears with the feed-rollers and with the shaft 50. The outer paper 76, after passing the guide-rolls 66, passes between the feed-rolls 77, at which point it meets the inner wrapper 80, which proceed Y from a roll conveniently placed. Where an inner wrapper is used, it is generally of oiled paper orsimilar material and is neither as wide nor as long as the outer wrapper. l/Vhen supplied from a roll a rate of feed different from that of the outer wrapper is required. The feed-rolls 77 consist of comparatively narrow disks placed to engage the outer wrapper only at its edges. These disks are sufficiently separated topermit'the inner wrapper passing between them. Feed- disks 78 and 79 are provided for the inner wrapper, the disks 78 being secured to the same shaft as one set of the disks 77, but are of smaller diameter than the disks 77, or at least those which are secured to the same shaft with the disks 77 are smaller than said disks 7 7 As they are equally rotated, it follows that the inner wrapper is fed a 'less amount than the outer wrapper.

The paper-feed rollers or disks 77 and 78 are given an intermittent movement and are driven by the shaft- 68, which is connected thereto by bevel-gears 69 and is itself driven from the shaft 50 by bevel-gears 70 and 81. The bevel-gear 81 is secured to a sleeve 82,

Fig. 3, which will slide freely upon the shaft 50,-but must turn with it. Aspring 83'holds the two gears together. When the two gears are in contact, the feed- rollers 77 and 78 are turned, and when the gears are out of contact the feed-rollers are not turned. The position of the gear 81 is controlled by alever 72, which forms or carries the armature of an electromagnet 71. The wrapper 76 is provided with a series of perforations spaced apart a distance corresponding with the length of paper required for the outer wrapper. Two contact members, as 84E and 85, which are placed in the circuit of the electromagnet 71, engage opposite sides of the pa-- per and are insulated from each other by the paper until one of the perforations in the paper is reached, when the circuit is closed, the magnet energized, and the bevel gear 81 moved out of contact with the bevel-gear 70, and the paper-feed rollers 77 and '78 stopped.

At about this time the knife which severe the wrappers is brought into operation. This knife is shown in detail in Figs. 14, 15, 16, and 17. 86 is a fixed top plate havinga slot 87, through which the wrapping-papers pass. 88 is a cutting plate or knife, which is held against the plate 86 by bolts '90, passing through inclined slots 89 in the knife-plate. Springs 92 beneath plate 88 form a yielding support therefor.

A lever 94, which is pivoted to the frame,

ICC

is connected with the knife-plate 88 to reciprocate it.- As herein shown, this lever engages a pin 93 on the knife-plate. As the knife-plate is advanced the inclined slots force it over the slot87, and the papers are cut. The lever 9a is actuated by a cam-95 on shaft 50 or by any other suitable means, so as to give it a quick and limited motion once at each revolution of the shaft. This motion is timed to correspond with the other parts, so as to drop the severed wrappers between the insertion ofsuccessive packages in before the feed can be resumed to supply the next wrapper, is accomplished by a device such as is shown in Fig. 18, which also shows the electrical circuits. The magnet 71 is the one which acts to separate the bevel-gears. 84 and 85 are contact members correspond- IIO ing with the contact members 84 and 85 of Fig. 3, which are placed on opposite sides of the paper. There are two circuits, one through the magnet 71 and lever 99 and contact members 84 and 85. The other is through the magnet 100 and the contact members and 106 and connected wires, as shown, and their circuit-wires.

The disk 102 is secured to turn with some rotating member of the machine, which, like the shaft 50, turns once for each complete wrapping operation. This disk has a circular ring 103, of some insulating material, which supports the contact finger or brush 105. The ring 103 is not complete and is completed by a segment 104 of conducting materia1,so that when the finger 105 is on the segment 104 the current is free to pass through said finger and the disk 102 to the finger or brush 106, and thus to complete the circuit. This disk is timed so that the circuit is completed through the disk and magnet 100 shortly after the current has been completed through the magnet 71. The lever 90, which carries the member 84, which makes contact through the perforations in the paper, forms the support for the armature of the magnet 100, so that when the circuit is completed through the magnet 100 the contact members 84 and 85 are separated. The inauguration of the paper-feeding movement inserts the paper between these contact members and prevents closing the circuit through them when they are brought together by the spring 98. The member to which the disk 102 is secured is not material, although as a matter of convenience it would probably be secured to the shaft 50.

In Fig. 9 is shown a skeleton-like construction for the feed-hopper. This consists of angle-shaped members 2*, one for each corner, thus leaving an opening at each side.

In Fig. 4 is shown a slightly-different arrangement of the mechanism in which two shafts 501 and 502 are employed as a substitute for the single shaft 50 of the other figures. The electromagnet 71 is also shown further removed from the bevel-gear and is connected therewith by a link.
