To all who/m. t may concern.

Be it known that we, JOHN E. FILLIN- GAMEh and JOSEPH M. Rmnoo'r citizens of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Wrapping Devices, of which the following is a specification.

This invention relates to a device primarily designed for use in pasting and applying wrappers to magazines and other periodicals for transportation through the mails, and by means of which paste or like adhesive employed may be automatically applied to the wrappers and the latter properly tensioned or drawn taut about the pub-l lication during the wrapping operation.

The primary object of the invention is to provide a wrapping device whereby the paste may be automatically applied successively to the wrappers as they are used, whereby the amount of time Aand labor required in applying the adhesive to the wrappers by means of a brush may be reduced and the wrapping operation considerably simplified and expedited.

A further Object of the invention is to provide means for supporting a pile or stack of wrappers of any desired thickness, in connection with a reservoir for the paste which is adjustable to permit any desired number of wrappers to be placed thereunder and is adapted to feed downward by gravity to effect the application of paste to the successive wrappers.

A still further object of the invention is to provide means whereby a prescribed amount of paste may be applied to the end of the wrapper to be pasted, and whereby in the process of applying the wrapper to a magazine the wrapper will be drawn as taut as desired and the paste automatically applied thereto.

Vith these and other objects in view, the invention consists of the features o construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which .z

Figure 1 is a top plan v iew ot a wrapping device embodying the invention.

Fi showging in dotted lines the movement `of the wrapper for applying 1t to the maga- 2 is a side elevation of the same,-

zine and actuating the paste hopper for the application of paste.

Fig. 3 is a section taken longitudinally of the device through the hopper, showing the same in normal position.

Fig. 4 is a View similar to Fig. 3 showing the hopper tilted for the paste spreading'action.

Fig. 5 is a sectional elevation showing certain features of construction;

The device comprises a base board or plate lof suitable size and form to support a pile or stack of wrappers 2, which are arranged in superposed relation thereon so as to be successively withdrawn for use one by one from the top of the stack.

The end edges of the end portions 3 of the wrappers, which form the pasted folds or flaps thereof, are arranged to abut against a `vertically and transversely disposed gage or stop plate 4 having a base portion or plate 5 provided with slots G for the passage of screws or like fastenings 7, whereby the gage plate is adjustably secured to the top of the base 1. By the adjustment oi' this gage or stop plate et the wrappers may be adjusted and positioned with reference to the paste discharge outlet of a paste hopper or receptacle 8 so as to vary the amount of the end portion 3 of each wrapper exposed for the application of paste thereto.

The hopper or receptacle 8 contains the paste or other adhesive 9 which is t0 be dispensed, and which is of su'licient iiuidity to enable it to be applied and spread in a desired manner. The hopper 8 is made oi metal or other suitable material and extends transversely of the base 1 and is of a length approximating the width of the wrappers 9.. As shown, the hopper is open at top for the convenient replenishment Vof the paste whenever required and is approximately V-shaped in cross section, its sides converging in a downward direction to provide a constricted outlet 10. This outlet 10 is controlled by a valve or closure member 11, in the form of a substantially circular body7 of rubber or other elastic material which is adapted when depressed to snugly lill the outlet 10 and cut off the outflow of the paste therethrough. The valve 11 is carried by a plunger stem 12 slidably adjustable in a guide 13 onthe front wall of the hopper and provided with a notch or linger piece 14 whereby the valve may be tion until it is forcibly depressed to closed' position. Y Y

The end walls of the hopper are provided with apertured brackets 15 .which slidably engage and embrace a pair of posts or standards 15 between whichthe hopper is arranged. By this arrangement the hopper is guided for movement between the posts in a vertical plane, allowing it to be elevatedv manually to permit a stack of wrappers to be placed beneath the same and also adapting the hopper to move downward by gravity so as to rest upon the upper wrapper vof the stack and so as to gradually and automatically descend as the wrappers are successively removed, to always dispose the outlet 10 in position-to apply the paste tothe wrapper which is in uppermost position. For the purpose of holding the hopper elevated while a fresh supply of wrappers is being placed in position for use, spring actuated dogs or latches 17 are provided upon the brackets 15 for engagement with keeper Vrecesses 18 in the posts or standards 16, whereby the hopper may be held in raised position, leaving both hands free to apply and adjust theA wrappers or to perform other incidental opera-tions, it being understood that before the hopper is so elevated the valve 11 is forced downward to close the outlet 1() against the discharge of paste. After the wrappers are placed in position for use and the hopper supplied with a suitable quantity ofpaste, the latches 17 are released and the hopper allowed to descend until its lower end rests upon the upper wrapper of the stack, whereupon the valve 11is elevated to open position. The paste thus descends by gravity and issues throught-he outlet 1() so as to come in contact directly with the underlying surface of the end portion of the upper Wrapper member 2,'in readiness foi a spreading application of a required amount of paste thereto.

The openings Vin the brackets 15 are of a size to allow said brackets to loosely embrace the posts or standards 16, thus adapting the hopperA 8 to tiltor rock in a forward and rearward direction on said posts or standards. F or the purpose of governing or regulating the degree of this tilting movement the brackets are provided with depending arms 19 carrying adjustable stop screws 20 to engage the posts or `standards 16, whereby the tilting motion of the hopper may be regulated to an exact degree as may be required for any desired paste applying action. Attached to the forward portion of the hopper and projecting beyond the front wall thereof at a downward and forward angle is av U-shaped'bracket 21 carrying a' transverse guide and tensioning roller 22V which normally rests upon the upper wrapper of the stack at a point in advance of the hopper. The weight of this bracket, and that of the valve, servesby gravity to normallyjtiltV the outlet portion of the hopper rearwardly, to the position shown in Fig. 8, in which position the lower edge 23 of the front wall of the hopper bears upon the; surface ofthe upper wrapper, while the lower edge 24of the rear wall of l the hopper is elev-a-tedf slightly above the surface of said wrapper, this arrangement allowingftheV paste to come in/contact withthe front of the wrapper in line with the outlet 10 and beneath the wall edge 24'.y as will be readilyunderstood. The hopper 8 is adapted tobe tilted during the wrapping operation in the oppositedirection, as shown! in F ig. 4, thus elevating the frontv edge wallv 23 andl depressing the-'rearl edge wall 24: of

the outlet 10,jfor;a purposev presently described. 1n this operationthe lower portion of the hopper tilts forwardly and rollers'25 are provided upon the.v end walls-'ofiy the hopper to limit such *tiltingV movement. These rollers are Ajournaled upon axes varranged in rear ofy the vertical longitudinal center of the hopper'andfare adapted to gage the surface of the uppermost wrapper 'for the purpose-described.while permitting,

by their rolling action, free outwardmovement of the `portion 3 ofthe wrapper from beneath the hopper during the application ofthe pasteto'ithe wrapper andthe application ofthe wrapper to the magazine or article 26 to which the wrapperE is being ap lied. ,l v

nv practice'the wrappers 2 may be previously addressed in anyy suitable manner, andthe addressed sides of the wrappers are arranged to face downward and the stack of wrappers 'placedinfposition upon the vbase 1 with the rvend edges-of their portions-3V disposed to bearupon the gagel,l which is adjustedto theproper posltion to regulate the amount of'such end portion disposed-forv the the wrapper. The y magazinel or article" 26 isv then laid in position upon the outer or forward end portionlof the wrapper and the extremity 27 of the latter the outer surface of thel magazine-*or between the leaves thereof, after which the magazine, with the-portion 27 of the-wrapturned over, asV indicated in- Fig.` 2', and'either' disposed upon per applied thereto, is folded over upon the body of the wrapper, as shown in dotted lines in Fig. 2, while the magazine and body of the wrapper are at the same time raised from the body of the stack, the arrangement thus being such that upon drawing the end portion 3 of the wrapper outwardly with the paste applied thereto and bringing the partially unwrapped magazine downward upon the face of the stack, the end portion 3 may be folded over upon the previously folded body portion of the wrapper and pasted thereto to complete the wrapping operation. When the partially folded wrapper and magazine are elevated to the dotted line position shown in Fig. l, at an angle to the end portion 3 of the wrapper, pressure will be applied to the roller 22 carried by the bracket 21 to lift the same, and said roller and bracket will thereby be caused to perform the function of a crank arm or lever, by means of which the hopper 8 will be tilted from the normal position shown in Fig. 3 to the paste spreading position shown in Fig. 4. The operator then draws end portion 3 of the wrapper outwardly from beneath the hopper during the motion of folding the outer portion of the wrapper initially about the magazine 26, the resistance of the portion 3 o the wrapper to outward movement being sufficient to cause a tension to be applied to the wrapper during the folding operation, whereby the wrapper will be drawn tautly about the magazine. 1n such paste applying position of the hopper 8, the edge 24 of the rear hopper wall is depressed into engagement with the surface of the wrapper, while the edge 23 of the front wall of the hopper is on the contrary elevated from engagement with the wrapper. Hence it will be understood that as the end 3 of the wrapper is drawn outwardly, during which the adjacent portion of the wrapper runs easily in engagement with the turning roller 22, the edge wall 24 will serve as a guiding edge holding the end 3 of the wrapper depressed while the paste is being applied thereto, while the edge 23 of the front wall of the hopper, being spaced from the wrapper, will allow a certain amount of paste to flow from the outlet over the end portion 3, the amount of which is governed by the dista-nce of the edge 23 from the surface of the wrapper, such edge 23 acting as a scraper to remove any excessamount of paste. Thus as the wrapper is drawn out,- wardly a film of paste, of a depth or thickness varying according to the degree of elevation of the edge 23, will be applied to the entire area of the portion 3 of the wrapper drawn beneath the. outlet 10, whereby the paste may be automatically applied in a rapid and eiiicient manner and the application of an excess amount of paste to the wrapper avoided. It will of course be un- -the application of the derstood that by adjustment of the stop screws 2O the movement of the edge 23 in the tilting action of the hopper, and its distance from the surface of the wrapper may be regulated, thus enabling the depth or thickness of the film ofpaste to be applied to the wrapper to be varied as desired or required under different conditions of service. After the portion 3 of the wrapper is withdrawn from beneath the hopper, it is turned over upon the folded body of the wrapper and secured thereto to complete the wrapping operation, and thereupon the hopper tilts automatically back to the normal position shown in Fig. 3 from the paste applying position shown in Fig. 4C, in readiness for the application of paste to the neXt succeeding wrapper of the stack.

The device constituting the present invention will be found of special value in saving time and labor in the wrapping of magazines and other publications commonly wrapped in a flat condition for transportation through the mails, the device saving considerable time and labor over the practice commonly employed of hand-applying the paste by means of a brush to the end portions 3 of the wrappers, as well as diminishing the amount of time and labor required in the folding of the wrapper and pasted edge to the body of the wrapper. With this device it is simply necessary to place a pile or stack of wrappers in position upon the base l and in proper relation to the hopper 8 and to fold the wrapper successively about the magazine, the hand motion required in this operation effecting the tensioning of the wrapper to the desired tautness about the magazine and the automatic application of paste to the free end of the wrapper, so that the wrapper may be quickly and conveniently folded over and secured. As the hopper S may be adjusted to different elevations, the number of wrappers contained in the pile or stack disposed beneath the same may be varied, so that when required all wrappers of subscribers within a given territory may be placed in position for use at one time, thus enabling the wrapping of magazines in accordance with a determined schedule to be conveniently carried out in a time and labor saving manner. It will be observed that the paste applying action of the device is such as to avoid the waste of paste and at the same time insure the application of a proper amount of paste to the wrapper and no more. 1n addition to the time and labor saved in applying paste to the wrappers, additional time and labor is saved in the use of this device in wrapping the. magazines or other articles in such a way as to apply the wrapper with a desired degree of tautness, since in the folding motion described proper tension Will be automatically placed upon the ivrap- While the invention is set forth as being designed especially for use in Wrapping 1naga- Y zines and other periodicals, it is to be understood that it may also be employed in the Wrapping'of any other articles fory ivhich it maybe found to be adapted.
