MEANS FOR WRAPPING UP TIN CANS OR OTHER ARTICLES.

Specification of Letters Patent.

Patented Ju1y'2'7, 1909.

Application led .Tune 22, 1906. Serial No. 322,924.

To all whom it may concern:

`Be it known that I, JAMES AUSTIN HoRNE, a subject of the King of Great Britain, residing at 7 Beatrice road, Stroud Green, London, England, have invented certain new and useful Improvements in Means for Trapping Up Tin Cans or other Articles, of which the following is a specification.

This invention relates to a means for folding or tucking in the overlapping ends of a paper wrapper that has previously been placed around a tin or other article.

In practice it has been found that by making the folding fingers of uniform height and width, and setting same at the same angle to the line of travel of the object to which the wrapper to be folded has been applied, it is impossible for all the. folds imparted by such fingers to the projecting ends of said wrapper to be formed so that they lie one on top of each other, and said folds have a tendency to spring away from the ends of the object instead of remaining closely applied thereto when such object leaves the machine, and so subjects said wrapper to the liability of becoming torn, or even stripped or pulled off the object during the necessary handling forv packing transporting and vending same.

The object of my improvement is to obviate the liability of these disadvantages occurring, and to produce nished wrapped articles of neater and more uniform appearance.

My improvement is illustrated in the accompanying drawing, in which Figure l is a longitudinal section through the machine. Fig. 2 is a plan view thereof. Fig. 3 is a transverse section through the bed or plate of the machine showing the folding fingers in elevation, and Fig. 4 an end view on a larger scale of the finished object showing the form of folds made by the folding fingers.

The apparatus comprises a bed or plate l of approximately the same width as the tin or object 2 to which the wrapper has been applied, and along which itis caused to travel either by inclining such bed toward the point of delivery, so that said object rolls down same by gravitation, or over which it may be propelled by suitable means such as an endless traveling band bearing on the upper surface thereof but to which I lay no claim as such means of propulsion are already known. On either side of said bed or plate 1 a series of folding fingers 3, 3, 3b etc., etc., one behind the other are arranged. The first of such fingers 3 (inthe line of travel of the object 2) is of less width and height than the succeeding fingers 3a, 3b, 3, etc., etc., same being approximately one half the height of thel latter (preferably slightly more) and also'about one half or slightly more than half of the width thereof, these differences in dimensions being for the purpose ofproducing the result to be hereinafter explained.

The numbervof the fingers employed will depend upon the number of folds it is desired to impart to the ends of the wrapper 4 in folding same against the ends of the object to which it is applied. The circumference of the tin gives the length of plate on whichthe folders or projecting pieces are fixed; the number of folds required givesI the number of folders orprojecting piecesthe number of folders are divided equally into the length of the platek and therefore gives their width, except that the lirst small folder on each side, being about half the with of the others, takes upf-about half the space allowed to it. The arrangement illustrated in the drawing shows the employment of five large fingers 3, 3b, etc., and the forward smaller fingers 3 in the front thereof, and if the large fingers are 1g in. in width, and the smaller forward one about 1 in., such an arrangement would produce six equal folds, one overlapping the other in succession, on a tin of 9 in. circumference.

The fingers 3, 3a, etc., may be made of metal, wood, or any suitable material.

In cases where a wrapper is applied to an object so that it only requires to be turned or folded down against one end thereof, only a single set of ngers 3, 3, etc., on one side of the bed or plate l will be required, the opposite edge of the bed or plate l 'being in this case provided with a flange or cheek to confine the object 2in its proper course over same during the folding operation. lhen the wrapper 4 has to be folded over both ends of the object 2 to which it has been applied,

the set of fingers 3, 3a, etc., has to be duplicated, those on the opposite sides being set at reverse angles, as shown in the drawings.

It will be seen that the front edge 5 of each of the fingers 3, 3, etc., is vertical, the top G being rounded off and merging by the curved surface 7 into the rear edge 8 of the finger. The outer surface 9 ofAv each finger also is the combination with a bcd over which the' A chainfered or beveled 0E from the near front edge to the back edge thereof, as show-n especially in plan in Fig. V2. The first or smaller and narrower finger 3 is preferably, as shown, set at a greater angle to the line of travel of the tin or other object 2 than the succeeding fingers 3a, etc. The effect of the employment of the first narrow and smaller finger 3 is that the first fold is not such a sharp fold as the others and lit is left wide open or away from the `tin so that the last fol-der will be able to make its fold under same, and the whole of the folds produced by the fingers will in consequence lie compactly one over the other with as little tendency as possible to spring or open outward even when the object 2 has left the machine. in order to insure good folding and malte a perfect tuck-in lof the loose projecting ends la of the wrapper, it is advisable to 4apply the wrapper Ll to the tin l so thatthe forward edgeof such wrapper arrives either in close, contact with the first or smaller finger 3,012 at. the same distance as the width of one of the larger folders therefrom.

That I claim and desire to secure by Let-1 ters Patent is y l. A wrapper folding device comprisingg article inclosed by the wrapper travels, of a set of folding fingers arranged at Yeach side of the bed and at an angle with the line of travel of the article, all of the fingers having their front and rear ends respectively extending outwardly and inwardly regularly and similarly in sequence and the first finger Aof each set of fingers being positioned at a khaving their front and rear ends respectively Vextending outwardly and inwardly regularly and similarly in sequence and the first finger of said set ,being arranged at a greater angle than the other fingers of the set, said first. finger of the set being approximately half the width and height of the remaining fingers of the set and said remaining fingers of the set being of uniform width and height.

In testimony whereof I have hereunto set my hand in presenceof two subscribing witnesses.
