WRAPPING-MACHINE.

Specification of Letters Patent.

Patented Feb. 22, rate.

To all whom it may concern:

Be it known that I, THEODORE G. MCGIRB, a citizen of the United States, and residing in the city, county, and State of New York,

have invented an Improvement in Wrapping-Machines, of which the following is a specification.

The present invention relates to machines for applying wrappers to articles, the object of the invention being to provide a simple, durable and compact apparatus for the purpose.

In a complete apparatus organized according to the present invention, there'is a vertical holder into which the unwrapped articles are put, the said holder being open at its bottom so that the articles may be pushed laterally therefrom, ahorizontally acting pusher or plunger for removing the articles from said vertical guide or holder and placing them over the wrapper, a vertically acting plunger which pushes the articles and the wrapper down a vertical chute provided with means for folding in the sides and ends of the wrapper and scrolls for turn- .ing in the corners of the wrapper to form of the same a five-sided box; a horizontally moving plunger for forcing the article and its wrapper into and through a horizontally disposed guide-way provided with means for laying the leading end of the wrapper down u on the article and with means for folding in the sides of the wrapper upon the article, said plunger beingv provided with spring means for folding in the follower or rear end of the wrapper upon the article before the sides thereof are laid down thereupon, as aforesaid. It is preferred that the wrappers should be fed and be severed from a roll or rolls by any suitable mechanism. The wrapper may have printed thereon any suitable or desired matter. I

The invention comprises features of construction, arrangements and combination of devices. hereinafter described and more particularly pointed out in the concluding claims.

The invention is embodied in the machine .illustrated in the accompanying drawings forming part hereof, in which Figure 1 is an elevation from the left hand side ofthe machine; Fig. 2 is an elevation fromthe right hand side of the machine with the side frame removed Fig. 3 is a lan sectional view upon the plane AA 0 Figs. 1

the lower part of the frame work.

and 2; Fig. 4 is a similar view upon th plane B B of Figsl and 2.

In the drawings, the reference A designates a suitable frame work in which the moving parts are mounted in manners ap propriate thereto, and B is a main or driving shaft having fast and loose pulleys B thereon. The said shaft B carries a series of cams hereinafter more particularly described.

The articles to be wrapped are placed in the vertical chute or guide-way w which is attached to a table t mounted on the frame work A. This guide-way to may be open at one side for convenience of access thereto as well as for observational purposes. pusher a is mounted in horizontal guides 11 attached to the table 73 and the pusher a has a part projecting through a slot in the table t, which part is connected at a with a lever a fulcrumed at a. The lever a has a stud? or roller a thereon which engages with the cam a fast upon the shaft B aforesaid, whereby the pusher a is reciprocated in its guides to cause the same to push the lowermost article from the guide-way (w over the wrapper on the table t. The table. If is slotted to allow the head 6 of the vertical plunger to move the article and wrapper downward into the vertical guide-way b. The head I; is carried by a rod 12 which works in the guide 72 attached to one side of the chute or guide to. The guide 6 is slotted at b for the headed stud b which is fast to the rod b A lever b fulcrumed at b", is rovided with a slot 1) which engages with t e stud b aforesaid, whereby the lever moves the rod 6 up and down in the guide b The lever b is connected at 6 with a pitman b, which pitman may be adjustable as to length and which is connected at b with a lever 5 fulcrumed on the rod C in T e lever 75 is provided with a stud or roller 6 which engages with the cam 1) fast upon the shaft B aforesaid, whereby the lever 6 is moved up and down.

As the plunger 1) moves the article and its wrapper downward the sides of the wrapper are turned at right angles to the underside of the article by the sides of the slot t after which the inclined folders f turn up the ends of the bottom of the trough-like wrapper, thus leaving triangular pr ecting parts of the wrapper at each corner of the cle on the platform 2) ready to be moved.

horizontally to complete the folding opera tious. At this point, the horizontally acting plunger 0 advances to push the article horizontally. The plunger 0 has a down wardly projecting arm 0 which arm passes through and is guided by a slot in the table go and is pivotally connected with a link 0 whose other end is pivotally connected with a lever c fulcrumed upon the shaft C aforesaid. A pitman 0 is pivotally connected with the lever c and is provided with a fork which slides upon the shaft l3 aforesaid and the pitman 0 is provided with a roller or stud which engages with a cam groove in the disk 0 which is fast upon the shaft B aforesaid. The cam groove in the disk 0" is proportioned to move the plunger 0 sufficiently far for the said plunger to push the article into the folders f and underneath the over-hanging layer i which is attached to the cross bar 9 of the guide-way h The folder or layer f presses down the forward end of the wrapper and its sides cxtendto nearly the edges of the articles,

whereby they force down the forward end fiaton the article and thus produce a neat and compact folding in ofsaid end. The

guide-way]; is detachably connected with the platform ;a by means of screws h. Attached and movable relatively to the plunger c is a folding finger which is provided with anup-turned end 0 slidalole on the rod 0 attached to the slide or plunger 0; a spring 0 surrounds the rod 0 and abuts against the end 0 and adjustable nuts 0" on the rod 0 whereby the finger 0 is normally held forward in position completely to push in and down the middle section of the end of the Wrapper before the plunger 0 begins ceding article alone the scrolls f and the guide-way it until the same are delivered at the right hand side of the'machine in Fig. 1. I The mechanism for feeding and cuttmg the wrappers is now to be described.

v A roller d is loosely mounted upon the shaft and above the roller (l are disks or rollers 01 mounted on a shaft (.5 the said rollers d 'co-aoting with the roller a to feed for were ceases wrappers are employed. The roller cl has a gear d fast thereto, which meshes with and drives a gear (Z attached to the rollers 03 or to their shaft (Z The shaft d has agear d loosely mounted thereon, whichgear (i is connected with the gear (Z by means of a ratchet wheel d" and a pawl (Z whereby the roller at will be rotated in one direction and not in the other as the gear 0Z is oscillated by the segment 0Z which is journaled on the shaft d of the frame work. The gear seg-. ment d is connected by a pitman with a lever (Z which is fulcrumed on the shaft C aforesaid and which lever is provided with a stud or roller (Z which engages with the cam groove in the disk (1 The roller d is held against over-throw by means of a brake, which, in the instance shown,'c'onsists of two pivoted arms at which enter a groove in said roller, and which are held against the roller by an adjusting device comprising the bolt and screwnut n. The arms n are pivoted on a support a mounted on the rod d. The friction of the brake is regulated by the bolt and nut n aforesaid. The wrappers are severed from the web or webs by means of a knife 6 and an edge e as the edge of the able t. The knife 6 is fulcrumed aforesaid and proportioned and timed to cause the knife to sever the wrappers from the web while the web is at rest. The cam e is connected to a sprocket wheel 8, loosely mounted on the rod (P, which wheel is driven by a chain s driven from shaft B by a wheel 3.
