SPECIFICATION formingpart of Letters Patent No. 724,538, dated April 7,

Appncatiuieuuneiz,1902. serialnaiinsto. (Nomen.)

To all whom, it may concern:

Be it known that 1, LoN BoNNEnoI, of Troyes, France, have invented a new and useful Improvement in Wrapping- Machines, which improvement is fully set forth in the following specification.

This invention has for its object a machine for wrapping pastils or cakes of chocolate or other objects, whether round or otherwise, in tin-foil or paper. The machine shown inthe drawings is specially intended for wrapping round pastils or cakes in tin-foil.

In the drawings, Figure 1 is a plan of the machine. Fig. 2 is a longitudinal section through the center of the machine. Figs. 3 to G are partial sections for showing the position of the dierent parts at different moments and for elucidating the action of the machine. Fig. 7 is a detail View.

a a are the pastils or cakes, and b the sheet of tin-foil in which the cake is wrapped.

The frame of the machine is formed of a foundation-plate 1, provided with four pillars 2, 3, 4, and 5. The pillars support a table 6, which carries a plate 7. 8 is a vertical shaft, upon which the controlling parts of the machine are mounted. The shaft carries a bevelwheel 9, actuated by a pinion 10, which is keyed to the crank-shaft 11. Three cams, the function of which will be later explained, are keyed upon the shaft 8. Upon the plate 7 a box 12 is fixed, which contains the pastils or cakes a to be wrapped up in tin-foil. They are placed in the box by any suitable means..

Figs. 1 and 2 show the parts in the position in which they are at'the moment the wrapping operation is about to commence.

The first pastil or cake of the pile, commencing from the bottom, is lodged, as shown in Fig. 2 in a recess in a movable piece 13, which slides under the box and which will hereinafter be called the carrier.7 The carrier 13 slides between the

guides

14 and 15, placed upon the plate 7. When the crank is turned, the cam 16 acts upon the roller 17 and causes the carrier 13 to advance into the position shown in Fig. 3, and the slide 18 is at the same time moved beneath the carrier by the returning-springs 19 and 2O in such a man ner that t-he cavity 21 in the slide coincides with the hole 22 in the carrier and with oriflee 23 in the plate 7.

Care is taken to ar- .the spring 31, which in what manner the same is the slide 18, above the cavity 21, a sheet h of tin-foil for wrapping the pastil or cake up in. As will be seen, the slide 18 is provided with

flanges

24 and 25 in orderto support the sheet of foil in position. The slide is formed of two plates, one above and the other below the table 6. The two plates forming the slide are held together by bolts, which slide in the

grooves

26 and 27 in the table 6. The pastil or cake a falls, pushing before it the sheet of foil b. 28 is a plunger, which by the effect of the cam 29 actuating the lever 30 then takes the position shown in Fig. 4. The plunger 28 is then raised by bears against the abutment 32, which is integral with the box 12. The abutment acts also as abearing or guide to the stem of the plunger. The pastil or cake a now rests in the orifice 33 of the table upon the lower portion of the slide. The slide 18 is moved into the position shown in Fig. 5, and in its travel folds the left-hand side of the sheet b over the pastil or cake a. The slide then comes, by the action of the cam 34, back into its first position, (shown in Fig. 2,) and in its travel folds the righthand side of the sheet l) (see Fig. 6) over the pastil or cake. The cavity 35, formed ip the lower portion of the slide, coincides with the orifice 33 in the table, thus allowing the pastil to fall. At this moment the Wrapping is complete.. At the moment at which the slide 18 commences to return to its first position the carrier 13 is moved back to its original position b v the returning-springs 36 37 and is ready to receive a new pastil.

Of course the present invention is not limited to the means for actuating the parts, which may be altered as desired.

Having now particularly described and ascertained the nature of` my said invention and to be performed, I declare that what I claim is-y 1. lu a wrapping-machine, a series of horizontal reciprocating plates provided with apertures adapted to receive the wrapper and the article to be wrapped, said plates arranged to slide one above the other in such a manner that the apertures therein will be successively brought into and out of register, thus folding the wrapper about the article.
