wnarrme-macnmn Specification of Letters Patent. Patented Dec. 13, 1921,

Application filed April 26, 1920. Serial No. 376,729.

To all whom it may concern:

Be it known that I, HARRY Y. ARMSTRONG, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Wrapping- Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters a of reference marked thereon, which form tive construction for thus wrapping the a part of this specification.

This invention relates to wrapping machines of that kind which is capable of takingsthe article to be wrapped, as a stick of chewing gum, and inclosing it in an inner wrapper, and an outer label wrapper, and

sealing the latter Wrapper and passing the articles so wrapped into an accumulating device, from which groups of a predetermined number are adapted to be extracted for further treatment, as, for instance, inclosed in a sealed group wrapper and a label group wrapper, if desired.

The invention has for its objects the production of an exceedingly simple and effecarticles, so constructed and arranged as to effect the several folds of the wrapper to produce individuall wrapped sticks by the use of simple, readi y operable, rugged, and durable mechanisms, and of a character whereby the machine has large output capacity by the use of mechamsms that are adapted to operate at relatively slow speed and short operative strokes, whereby the machine runs smoothl [and without jars or vibrations characteristic of known so-called high production machines, thereby avoiding the racking effect of excessive vibration heretofore observed in high production machines.

A further object of the invention is to provide a novel mechanism for causing the articles to pass through the machine while bein wrapped, designed to avoid severe han ling-0f the articles and wrappers and thereby breakage thereof, with consequent clogging of the machine, a feature which adapts the machine to continuous operation and saving losses of time in keeping the machine clear of clogging impediments, as broken articles, torn paper, and the like.

vAnother object of the invention is to provide an improved mechanism for advancing the articles, such as sticks of chewing gum, whereby the articles are not subject to severe impacts or urging parts, which tends to crush soft articles or break dry and more or less fragile articles.

Another object of the invention is to provide, in connectionwith a reciprocable carriage means, an intermittently swingable or. otherwise movable stop element, the function of which is to hold or arrest the articles when the carriage is traveling in one direction so as to cause the articles to be displaced in and relatively to the carriage in such direction that when the sto element is released from the article hol ing position, the articles travel bodily with the carriage in the reverse direction and are thereb advanced through the machine and relative to wrapping mechanisms by which the articles are wrapped.

Another object of the-invention is to pro: vide, in a wrapping machine of the character described, a reciprocable carriage, having thereon and movable therewith a rotative folding element to receive articles and their wrapper to partially fold the wrappers about the articles during the reciprocable and turning movements of the carriage and folding element, respectively.

A further object of the invention is to provide, in combination with such reciprocable carriage and rotative folding element, stationary folding means to partially effect wrapping of the articles, together with means cooperable with the re'ciprocable carriage, to intermittently displace the articles rearwardly and through the stationary folding means and to release the wrapped articles from the carriage.

A further object of the invention is to provide novel means of transferring the articles from a stack thereof in a swinging or movable magazine to the wrapping mechanism, constructed an operating to effect such transfer by a relative total movement A further object of the invention is to prov1de a novel wrapper cutting and feed -device for cooperation with a swinging or means to release the bottommost article from the stack in such a way that the stack is at all times supported by means at the magazine bottom which constitutes fixed means to release the articles from the bottom of the stack when the magazine is swiliiging or moved to and fro in its limited pat The invention has as other objects to provide means to correlate and operate the mechanisms above set forth, to give proper combinative effect thereto in'a unitary machine, and the invention consists in the com bination and arrangement of the parts shown in the drawings and described in the specification, and is pointed out in the appended claims.

Figs. 28 and 29 show progressive steps of applying the said label wrapper to wrapped gum stick. 7

Fig. 30 is a perspective view of a group of gum sticks in readiness for sealing.

The invention is herein illustrated as applied to a machine for wrapping sticks of chewing gum and like articles, taking a single stick, progressively wrapping it in a suitable inner oiled or waxed wrapper W cut from a strip of paper unrolled from a with its side flaps w, w, overlapping,-

and with the end fiapsj w w laid in, as best shown in Fig. 26, then wrapping said stick so Wrapped in an outer or label wrapper L, to which the initially wrapped sticks are presented, in the manner shown in Fig. 27, with paste patches applied to one side lap Z, the label wrapper being progressively wrapped-about the initially wrapped stick in the manner shown in Figs. 28 and 29, and by the mechanism hereinafter described, the paste-bearing side flap being pasted over the oppositeside flap Z to complete the application of the label wrapper, with the ends of the labeLwrapper extending over and confining the end flaps 'w.

wrapped sticks are thereafter brought together in the group containing a prescribed number of pieces, after which the group may subsequently be sealed or otherwise handled, depending upon the practice of the manufacturer. i

The embodiment of the invention illustrated in the drawings contemplates the utilization of a reciprocable carriage, one or more intermittently rotatable, side folding elements'movable with thecarriage which move or moves separately over the sticks, together with a wrapper or wrappers, fed

by suitable mechanism across the path or paths of the gum sticks, as they are released rom the magazine, or other part of the mechanism, and a suitably constructed and actuated stop element which cooperates with the reciprocable carriage to arrest the gum sticks in space so that they may be prothe gum sticks and their wrappers W are directly released from the magazine. If a label wrapper is to be applied, as shown in Fig. 27, two of such side wrapping folding "elements are employed, one at each end of the reciprocable carriage, the latter to re-' ceive the gum stick after it is fully wrapped and to apply the label wrapper L thereto.

The carriage has a relatively short reciprocating movement and the swinging or otherwise movable stop element cooperates with the carriage when in full action to arrest a series of gum'sticks in space, to allow the carriage to move forwardly relatively thereto, so that when the stop element is released from the gum sticks and the carriage moves rearwardly the gum sticks bodily move with the carriage mechanism and are wrapped by the folding mechanism. After inner and label wrappers are applied to the gum sticks the finally wrapped sticks are released into a space to receive a number. of sticks to make up a desired group, and the groups may be removed for further wrapping, if desired.

All of the above referred to mechanisms,

excepting the magazine for the gum sticks,-

the mechanism for cutting and feeding inner wrappers, the stop elements for arresting the gum sticks in space while the carriage wrapping slot passes ther-cover, are carried by and reciprocate with the carriage.

The carriage is designated as a whole by- 17 and is mounted to reciprocate by means hereinafter described on a suitable frame 10, in which is journaled a shaft 11 (Figs.

suitable motor. Said shafts 11 and 18 are provided with meshing spiral gears 19 and 20, respectively, (Figs. 3 and 5) through the medium of which the counter shaft is driven by the drive shaft. The drive shaft 18 is also rovided at the rear end of the machine (Fig. 1) with a pinion '21 which meshes with aar- 22 arranged on a short horizontal sha 24 parallel to shaft 18. Said latter shaft 24 is provided with a beveled pinion 25 which meshes with a beveled gear 26 arranged upon a shaft 27 which, in the complete wrapping and sealing machine,

is adapted .to actuate mechanism for trans-' ferring a group of wrapped gum sticks to a single sealing mechanism which may receive groups from a plurality of sidewise I mechanisms can be located in rear thereofand in a vertical plane between the vertical planes of the wrapping mechanisms. The total sea-ling mechanism is not here shown,

only sutficient to show its relation in the combination. This arrangement is an advantageous one lnasmuch as the speed of the sealing mechanism 1s relatlvely slower than the wrapping mechanism because the sealing mechanism handles groups of gums, while the Wrapping mechanism handles in.- dividualgum sticks; therefore, it becomes possible to operate two wrapping mechanisms serving a sin 1e sealing mechanism at desirably low spec while maintaining the output of the machine high Both wrapping mechanisms, including the gum and label magazine and wrapper folding and cutting mechanisms, as well as the stop elements and actuating. means therefor, are substantially alike and the description of one unitary wrap-ping mechanism will apply to the other. In the following description, therefore, the parts will be referred to in the singular except where the context indicates otherwise.

. The magazine 13 in whlch the gum sticks to be wrapped are stacked is pivotally mounted upon a shaft 28 carried by the upper ends of standards 29 that rise from and are secured to the bed of the machine frame. The standards 29 also carry reels 30 for rolls of inner wrapping material W such as wax paper, tin foil, or the like. The wrapping. material extends in a. wish in front of the magazine and is intermittently fed from the roll and has a portion thereof severed from the web by a Suitable cutting mechanism to provide an inner wrapper W
