used for wrapping candies, such as suckers or other similar articles which are or may be supported on a stick. I

I The principal object of the invention is to provide a machine of the above type which will wrap and at the same time seal the wrapping material about the candy on the stick, by the application of heat, and without the necessity of twisting the wrapping material about the stick and candy. V

The invention also embodies instrumentalities and parts designed to bring about the above mentioned results and in such accomplishment reducing the amount of wrapping material requiredto a minimum--the suckers being fed into the machine manually.

The machine also embodies as few parts as possible consistent with a practical application thereof to the purpose intended.

The invention will be clearly understood from a perusal of the following detailed description, taken in connection with the accompanying drawings, and wherein: I v

In carrying out the invention there is provided a table or other suitable support I on which is mounted a drive shaft 2, with a power pulley 3, the shaft'being supported by the bearings 4. A driven shaft 5, supported by the bearings 6, is also mounted on the table I and is in operable connection with the shaft 2 by means i cam I2.

of the gears I and 8. The driven shaft 5 has mounted thereon in proper spaced relation a wrapping material feeding cam 9, a knife cam III, a plate sealing cam II, and finally a plunger The material with which the candy or other article is to be wrapped is carried on a mechanism (not shown) butwhich may be disposed on the table at the point A. This material, preferably Cellophane, is drawn off a supply spool, reel or drum by means of the parts embodying the wrapping material feeding mechanism. This consists of the parts such as a cam 9,the bars I3, on which are carried a small roller I4, the roller being held in frictional contact withthe cam 9. In Figure 6 is shown a detail of the cam 9'andits 'co-acting parts, its roller I4 and the bars I3. 'Thes'e bars I3 are shown broken away in' Figure 1 for clearness of illustration,'but the construction is such that their outer ends are pivoted to the spaced arms I5 by means of a single piece of material IE, the latter carrying a pin H which is adapted to he slid in the grooves I5a in. each of the arms I5. The arrangement includes also a ratchet wheel I 8, mounted on a shaft I9Yand having bearings in the block 20. Mounted on the shaft I9 is a bevel gear 2 I. To completethe wrapping material feeding mechanism assembly, there are providedthe roller I4-a mounted on the shaft 22, and wheel 23 mounted on theshaft 24, the shaft 24 having one bearing in the block 20 and its other bearing in a support 25., The shaft 22 is supported in the blocks 25-a and has also mounted thereon a bevel gear 22a which meshes with the, gear 2I in bringing about a stepped or periodicrotation of the wheel 23 and 'the roller I4--a. A pawl 26 under spring tension rotates the ratchet wheel I8 at such time as the arms I5 are moved downwardly by rotation of the shaft 5.

Thewheel 23, see Figure 7, is provided with adjusting means by the springs 23a mounted on the pins 23-h, so that the wrapping material may be controlled in the feeding thereof between the roller I4--a and the wheel 23.

The machine provides for cuttingthe wrapping material into proper lengths by means of a stationary knife 21 and a movable knife 28. The

movable knife 28, shown in detail in Figure 10,

a thrust rod 34-e, the pivot pin P being stationary in the frame.

For reciprocal action of the sealing plates 36 and 31, there is provided a cam H, mounted on the shaft and coacting with a bar 39, carry.- ing a small roller 40, the bar 39 being pivoted as at 42 to the table.

In Figure 3 is shown the means for moving the sealing plates to operative and inoperative positions and for this purpose there is provided,

and as shown in Figure 2, and disposed under neath the table top I, a plate mounted on the legs 4|, the legs being supported by a crosse piece 4la. There is also a plate 42, the latter plate having connected thereto a resistance c'oil (not shown) for generating heat to be imparted to the plates 36v and 31 byan electrical circuit through the wires W. The sealing plates 36' and 31 are supported on the plate 40 and are held in slidable position thereon by the strips 43 and 44. The plates 40, 4I a and 42. and the table top I each include an'opening O which are in register to permit the suckers to be dropped into a basket. This basket is preferably made of four pieces of clock spring indicated at C and spaced apart as shown.

The arrangement for sliding the 36 and 3'! laterally to and from contact with the article to be sealed and wrappedis. provided for by the angular arms 45 in connection with the bar 39, previously referred to, and to which arms bar 39 is connected through a bar 46. The latter bar is' pivoted to the arms 45 at the point 41 and each arm 45 is pivoted to swing on a stationary pivot pin 48 secured to: the underside i j, of the table top I.

being shown in engaged position in Figure 5-.

the sealing plate 36' then, being between thetwo pieces of the plate 31. The sliding together of these plates advances the notches N against a sucker S and the previously heated platesseal the wrapping material on the candy and the stick S-2 thereof. i

The machine provides means in the, form of a plunger for thrusting the article from the machine and also for causing the sucker to be dropped from the basket when they wrapping and sealing has been accomplished.- .This. plunger consists of a rod 48 with a cone-shaped or flared end 49se'e detail view in Figure 1 2. A member 59, having a bored passage, formed integrally with and supported by a frame 51,; holds the plunger in operable position and permits the rod 48 to reciprocate therein. A cross-arm 52 is connected to the plunger rod 48 and has pivotally connected thereto two swingable arms 53 and to the latter are pivoted the spaced bars 54. The bars 54 terminate in ahead piece 55. A stub shaft 56 is passed through the head piece and is connected to an arm formed of the two parts 5l-and a piece 59. A roller 60 carried on the two parts 51 of the arm. is thus held in contact with the cam [2.

sealing plates being shown at 6|, a similar spring being employed with the knife, but not shown, a spring 62 for the bar 39 and a spring 63 for the arms 54 of the plunger.

The. articles to be wrapped and sealed are fed into the machine by hand, the sucker. being held by the stick S2 over the opening 0. The plunger 48 with its flared end 49 makes a downward movement, the article carried on the stick is knocked from the hand, the stick being projected upwardly into the member '50 and the candy is shoved downwardly through the opening Q into the basket, where it is held against the springs C. The knife 28 having been previously lowered in the severing of the wrapping material at the same time the bar 3 4;a was depressed and advanced the "rodnt l-re in bew e t r n G-,-t .u h d ng th ti le n position. As soon as; the article is sealed- -bythe movement inwardly of the sealing plates 35 and 31, the plunger again descends and ejects the article, through the opening Oth e rod 34i -e having been in the meantime retracted from between the springs C astheknife rises;

Themachine is susceptible of some modifications, changes and alterations in keeping with the spirit thereof and such as would be within the scope and meaning of the claims appended hereto.
