This invent-ion relates to certain new and;l Auseful improve-ments 'in Amachines for wrap; ping'or enveloping candy, either in the formv 4of drops or sticks,

` -tion of the core is substantially Fig, 5, a longitudinal sectional Fig.' 6, isa

of Fig. l Fig. 8, a side elevation` with adjacent parts; and Fig. 17, a sectional view'of the clamp for the gripper spindle.

- `The letter A designates the bed or topol ourmachine. It is mounted upon legs B,

ypreferably connected together bybase rails C. On the bed plate A are mounted standards D whichsupport a drum E- on which is wound and supported along strip of paper F which passes under guide-bars .G and over a guide-bar H, all supported in a frame I on, DAYTON, onto.

mounted on the bed piece. l Collars J, held by set screws, serve'to guide the paper strip by engaging with its edges. -The collars may be set in or out to agree with the Width of the strip. (See Fig. 1.)

Secured to the frame I,is a guide core K, preferably made ofsheet metal and curved in the Iirstportion of it so `as to guide the paper strip smoothly under it. The crosssecsemicircular, as suggested in Figs. 1v and 5, and clearly shown in Fig. 6. About the point where the curve of this core terminates, commences the paper guide conduitL also preferably made cular cross section, as suggested in Figs. 1, 2 and 5 and clearly shown in Fig. .6 and other detail figures. andthe guide conduit L is left suicient for the ready passage ofthe paperstrip. -The guide conduit extends to the point M where it is formed into a tube.

`J ustbefore/the part place' in the conduit whatwe term the hopper which is shown at O, Figs..1, 2, 3, and 16. This hopper see Fig. 16 is substantiallya tube,

A space between thecore K 'f M of the conduit, we f being'cut open atene side and having its edges flared ont to'form an opening P for receiving the candy or other articles. The remainder of the hopper, the tubular part, projects onward in the conduit. 'lhe hopper is provided with a bracket Q which spans the conduit and tits upon the bed-plate where it is detachably secured by spring latches R.

- Thus the hopper issupported in the conduit with a space between the hopper and conduit for the passage of the paper just as is the case between the guidecore K and the conduit.

At S a sleeve is placed over the conduit, the sleeve being openas seen in Fig. 13 so that it can be sprung to slip past the tubular part IOO.

. 75 of sheet metal and of substantially semicir- M of the condui-t. This sleeve performs two functions, first, that of engaging with the up per projecting edges of the paper strip and turning them toward each otherso section into a tubular form as it passes between the hopper and the conduit at the point where the sleeve S spans or encircles the conduit; secondly, the function of the sleeve S is to support spring arms T which carry at their other ends, theoverlapping jaws U thereby forming what we term the article holder. These overlapping jaws U hold the article after the paper is about it, while, in the initial operation, the

blank is disposed of, andwhile the paper of the first article is being twisted, these jaws hold the second wrapped article, and so on as the -machine is operated.

Now in order to project th article along from the mouth of the hopperthrough the tubular part of the hopper and thence into the paper tube, which latter is shown at V, being that part of the strip from the sleeve S to the end of it in the direction of the right hand as viewed in Figs. 1 and 2, weprovide a feed rody or plunger W which reciproeates in the conduit and through the hopper so as to force the articles frpm the hopper into the paper tube to about the point indicated at X in Fig. 2. The plunger is reciprocated, preferably by means of a bell crank lever Y, with which it engages as seen at d a cam-mechanism and elevated by a sprin g c, as will hereinafter appear, so that the plunger is automatically and regularly reciprocated,

The next mechanism to operate in the machine is the reciprocating gripping device. This consists of a head d, mounted in ways e, of the bed A,and carrying a sleeve or hollow shaft f, rotated by a flange g and pins h, which are engaged by pins fi, carried by a pulley j, operated by albeit b" and mounted on a hollow shaft or sleeve l mounted in a stationary head m, itself secured in a fixed position by a set screw o in the ways c of the bed A. Thesleeve or hollow shaft f has pivoted therein two grippersp and q the enlarged inner ends of which are respectively notched to receive the knobs lr and s of the yoke t, forming a part, of the gripper shaft u, mounted in the f and l. close the grippers.

This shafty operates to open and Referring to Fig. 12 it will be seen that the grippers are closed. Let it be supposed that they arekto be opened and that the sliding head d is/to be advanced so that the grippers can take hold of the projecting end of the paper, as seen in Figs. 8 and 9. The shaft lwis frictionally held bythe friction clamp fu, w, mounted in the hollow fixed standard s'. When the head d advances toward'the paper paper blank ahead of theV article is being twisted.- When this paper.

Z. This lever is` y actuatedby a pitman a, connected with a piv- 1q l oted bal: b,which is depressed by sleeves or, hollow shafts lment-of the head d' causes l ticle and the holder-U,

lshould have been {L '1. r. delayed by this friction clamp. to open until the the knobs r and s the shaft u is i This causes the grippers shoulders a and b strike that the respectively. This done the shaftuis thrown -strip is changed from a gutter form in cross through the clamp, the spring c acting on the collar d assisting in moving the rod through the clamp..` When" the grippers arrive at the paper they are to be closed from the position shown in Fig. 9.to that shown in Fig. 8. This `is done when the head d returns and draws the grippers against the knobs fr and s. This done the further return movethe grippers to press harder and harder against the knobs, the tendency beingto make the grippers bite harder and harder upon the paper. hen the pressure of the grippers against the knobs overcomes the friction in the friction' clamp and the tension of the spring c', the shaft u moves back with the head. The paper tube is, during this return movement of the lhead andl grippers, being drawn out L and the holderU sothat by the time the head d is at its returned. position the paper and contained article have assumed the position shown in Fig; 8. At'this time also the pins h are being engaged by the` pinsz' and the grippers rotated so at each side of the article, Fig. 8. -n

The next device to come into operation is the shears or scissors by which the `paper is clipped. This device consists of two pivoted blades e', f which act like scissors, their pivot being fastened in a suitable part of the frame, say the upper part of the bracket h'. The shears are located so as to clip that part of the twisted paper which is between the arallowng a projecting end for the grippers to take holdof in the as also shown in `next operation.

designates a plate having oblique slots j which receive the antitriction rollers 7c' of the studs Z in the lower ends of 'the shear blades. This plate t" is carried by the reciprocating rod 'm' mounted in the bracket h' andY slotted at' its lower end, as seen at o to straddle the cam y shaft p. A spiral spring q presses against the bracket h and against a collar fr on the rod tm so as -todepress the rod and uickly close the shears, so that they will clip t e paper. A cam s" mounted on the shaft p' engages an antifriction roller t on a stud u' carried by lifted against the spring and the shears opened.` Thus the shears are operated, being quickly closed by the spring action and being opened by the cam action.

In describing the operating. mechanism it stated that the standard k, which supports the shaft p is slottedas shown at l in Fig. 11 so as to guide the rod b. It should also ave been stated that a standard m" supports the bolt o" of the bell# as to twist the paper the rod m whereby the rod is of the conduit TCO - perhead returns to deed anything'that is to crank 'lever formed of this rod and the arm c". The shaft p also carries a gear wheel e' which meshes with a pinion w carried on the shaft w mounted in the bracket z,'which bracket is a part of the head m., A pulley a carried by the shaft drives a belt'b" by whichthe pulley j is rotated to rotatey the grippers, as above stated. The head d is reciprocated simultaneously with the reciprocations of the plunger rod W by the arm c which is in eiect arigid extension of the pivoted rod b. In other words a bell cranklever is formed of the arm c and therod b. Motion is given this bell crank lever by the cam d mounted in the shaft p and engaging with an antifriction rollere fixed collars f on the rod or portion of said bell crank lever markedb. To compensate for the arc described by the arm c" of this bell-crank lever the pin g reciprocates in said arm see Fig. l12 and is pivoted to the head d. The shaft p is preferably rotated by power applied to it through the pulley h. But two devices remain to be mentioned, namely, the box 12 in which the articles are kept to form av supply chine; and thereceptacle j into which the wrapped articles drop, this receptacle being placed suicien'tly at one side of the machine to catch the articles as they fly out of the machine on account-of their high rotary speed at the moment when the'paper is-clipped.

We have incidentally described the gperation of the machine in connection with the above description of its mechanismg but in order that, it may be more lfully understood we would observe that in the first placethe paper strip is fed by hand before the machinev is startedup, that is,.the initial feed i's done by hand. After that the paper is drawn'automatically throfugh the conduitby the action of the grippers when the Ireciprocating gripwhat may be called'the normal position. The papel' having been fed in the first instance by hand, an article, say a candydrop, or a lemonor an orange or inbe wrapped, is

dropped ntothe hopper when it is projected by the plunger rod to the position shown at X in Fig. 2. This done the gripper head advances yand the grippers take hold of the projecting tubular-part of the paper and draw out what may be called a blank, twisting and cutting it olf. This blank goes to waste, but

in drawing it out the paper is advanced iny the conduit until the article is moved along with the paper tube from thepoint X to within the spring holder U. nere it is had unu the gripper head again advances and takes hold of the projecting end of the paper and draws the paper out, taking with it the con tained article. We have before stated that as the gri ppers advance to the paperthe plunger rod reciprocates toward the hopper. Therefore as one article is drawn from the point X another will have taken its place, so that -cle is being wrapped by playing between cle, and grippers to take -means to reciprocate and for feeding the ma- 'with a conduit wh into the tubular as an article leaves the holder and enters the holder. Thus while oneartithetwisting process another is in the holder and the paper tube .is beingclamped about it by the holder so that the paper is held from rotation and from twisting by the holder, causing 'the twists to take place only in the unfilled part of the Shown in Fig.8. These operations'are repeated in rapid succession and the articles are wrapped with great rapidity andwith uniformity, as has been ascertained by practical tests Aof this machine. l

Having thus fully described our invention, what we claim as' new, and desire to secure by Letters Pate-nt, is-
