papers. circulars` folders and the like which do not have stifl" backs or covers. It relates more particularly to a device of this charl acter by which the article may be bent through the middle portion and the edgesl 'brought together, by which one edge of a wrapper may be lapped or folded around one edge ot' the article before it is entirely lolded and the other edge of the. wrapper may lie lapped or folded around the edges of the article after they are 'folded together. By this device the wrapper may be guiniiied and pasted during the wrapping process l5 and the wrapper may be so applied to the article that the danger of its becoming displaced or torn off accidentally is minimized. Heretofore wrapping machines of various sorts have been made .forwrapping niaga- 50 zines, etc., in which, for example, the niagazines were rolled np with a wrapper whose oiiler edge projected and was pasted down. In such cases the springiness of the paper often pulls the Wrapper off unless a long time is given for the paste or glue to dry. .ln other machines the entire wrapper is wound, usually by a plurality of turns, around the entire article leaving a cylindrical package that is inconvenient for stacking. mailing and handling. By the present invention the article is folded flat and a sharp bend in the wrapper at the proper placevhelps to eliminate the danger of theu pasted portion being torn 45. loose by the tendency of the folded article` .to unfold. '.l'l'iis and other advantages will be more clearly understood as the description proceeds. The invention will be particularly described in connection with wrapping magazines although it is to be understood that it is not confined to wrapping this article.

The article to be folded and wr pped, such as a magazine.. for example. should be narrower than the wrapper that is to he placed around it. In the drawings. reference character ill represents a flat table or board upon which the elements for wrapping the along the line 22-2 224323 articles are mounted. The right hand end bf this board shown on Fig. 3 will be called the front end and the left hand end shown Ion Fig. 2 will be called the rear end. Parallel strips 31, L-shaped in cross section, are mou ted on the board 30 to form a guide- Way for the wrappers, the front ends of `these strips flaring outwardly to provide a llconvenient entrance. These strips 31 are provided with slots through which thumb screws 32 pass so that these strips can be adjusted at different distances apart to aecommodate wrappers of different widths. A number of parallel bars 33 are mounted on the top of the board 3U, five being shown, two of which bars extends from one end of the board 30 to the other. A similar set of parallel bars 34 are mounted above the oard 30 by means of angle irons 35 iu a slightl r higher plane than tbe bars 33. These ars serve to catch the magazine as it is dropped on top of them as will be explained below and they extend only a short distance along the board 30. Parallel strips 3G, which are fastened to the board 30 by means of adjustable holders 38, serve as guides for the magazine, one of these strips 36 being provided with a wing 3T bent upwardly and outwardly to causethc magazine to drop in place 'when i'cd to the device.

vStops 39 held to the board 30 by adjustable brackets 40 serve 'to prevent the magazine from being thrown too far to one side of the device when it is fed thereto. Two pairs of endless tapes or bands 41 are mounted so as t0 be within the channel formed by the guide strips 31. One endless band. of each pair is above the other one. These bands pass around rollers 42 which are mounted in adjust-able brackets 43 and 44 (Figs. l and 9), the ones at the rear end only being shown on the drawings. These bands are so dis osed that the lower side of the upper one an the upper side of the lower one contact slightly so that the edges of the wrappers can be passed between them and be carw ried along as the bands are revolved, which can be done by any convenient means (not shown). The pairs of bands are approximately, as far apart as the wrapper is wide.

A sprocket chain 45 carrying extensions or lugs 46 spaced at proper distances ap. rt passes around a driving sprocket 47 (Fig. at the rear end of the device and around a loose sprocket 48 (Fig. 3) at the 'front end of the. device. The sprocket 48 is carried by a shaft 49 which revolves in bearings 50 at y iuched to the lower side of the board 30. 'lhe shaft 51 to which the driving sprocket 4T is rigidly attached, is mounted in bear ings 52 beneath the board 30 and this shaft together with the sprocket 47 is driven by means of the driving pulley from any convenient source of ower. A bevel gear 54,7is mounted on the s raft 51 to turn there- 1, 4 and (5 comprises four uprights or stand Yards 60 upon which are mounted, on opposite sides, two shafts 62 that revolve in bearings 6l on the standards (it). Mitre gears (Sil on thel ends of the shafts (i2 mesh with and'are driven by mitre gears (54 on the shaft (i5 which revolves in bearings (36. The sha'i't (35 y has rigidly attached thereto a toothed wheel (57`which has the teeth on its outer periphery. A lever 68 is loosely mounted on the shaft 65 and has its outer end slotted. This lever G8 carries a pawl 69 actuatedl by a spring 7U to come into contact with the teeth on the toothed wheel 67. A link Tl which has its lower end adjustably mounted in the slot of the lever (38 carries a cani roller 72 near its upper end which upper eitd is bifurcated as shown at T4 to straddle the shaft 56 and be guided thereby. A cani T3 is mounted upon and revolves with the shaft 5G and thereby moves the link 7l longitudinally by pressing against the cam roller 72 and a spring 75 returns the link 7l which draws the same upwardly when the lower part oi the cam edffe is correspondingly turneihtho action of the cam 'w73 and spring 75 thus oscillating the lever 69 and causing the wheel (57 to be turned as the pawl G1 ratchcls over the teeth in one direction.

Each of the shafts 62 carries thetwo sprockets 77 over which endless chains 78 pass. These chains each carry at intervals horizontal bars 79 alud on their inside travi-l they press against upright strips Sl) hcld in place by cross pieces and al. the top of the chains 78 they pass over sprocket wheels Additional upright guides 8l are prin ided on the side of the feeding device next to thc board 30.

Parallel bars 83 are joined by cross bars 84 to form a frame or rack for carryingr a package or slack of magazines. This frame rests upon .the bars 79 attached to the chains 78 and is gradually raised as the device is driven. The upper ends of the bars 8l are bent horizontally as shown at 85 to vform a temporary rest for the niagazines they are shifted from the package stack.

At the top oi the standards {il} two parallel bars 8i' are fastened to i'orm a trackv which extends over the board 30. A frame SS having channels 89 along`the corners thereof slides to and fro on the tracks 8?. This frame 86 carries an adjustable hook or puller 90 on its rear edge.. Two brackllU lil)

The for- Ward portion of the guide Way 255 beyond the lip 264 is bent downwardly as shown at 26S (Figs. 20 and 25) and an opening 269 provided therein for the purpose ot permitting the ends of the elements 270 of the brush 271 to pass therethrough as the. brush is revolved.

The operation is as follows: A magazine wrapper fr is placed between the, guides 253 and a magazine Ma. is placed thereon between the guides 254 and then thepivoted projections 252 carried by the chain 251 are brought into Contact with their rear edges to move them forward. As they are moved forward the central portion thereof passes beneath the wheels 260 and 261 and are prevented rd'm'heing raised while their edges are curved upwardly (Fig. 22) and also while the cam 256 turns the extreme edge of the wrapper at a. right angle. As the two are. moved forward to the position shown in Fig. 23, both sides are turned into a substantially vertical osition and the extreme right hand edge oi) the Wrapper is further bent at a right an le b pending lip 263. urt ment of the two to the sition shown in Fig. 24 causes the left lind edge of the wrapper to be bent horizontally by means of the horizontal portion 264 (Fig. 24) of the guide 255 and when itpasses over the, wheel 266 the adhesive is applied to the lower side thereof. Further forward movev ment of the two causes the downwardly projecting portion 268 of the guide 255 (Fig. 25) to turn the edge of the wrapper downw'ardly after it has passed beyond the end of the guide 256.k Brush 271 then brushes through the openinlr 269 against the overJ lapping edge of the wrapper and causes the. same to be. stuck. During the time the projections 252, carried by the chain 251, are moving the magazine and wrapper through the channel formed by the guideways 255 and 256, they are gradually turned upwardly as more elearlyr shown in Fig. 2A by the gradually curving portions of the guideways 255 and 256 and again droi3 into open position when they have passed eyond the channel formed by these guideways.
