Application filed October 14, 1927. Serial No. 226,090;

This invention relates to improvements in mechanism fordepositing a predetermined number of articles into a receptacle.

The primary object of the invention is to 5 furnish a machine adapted to fill a series of cartons, each with a predetermined number of small articles, such as candy tablets or the like, while the cartons are intermittently fed alon a runway which leads them to a carton O 10 closing mechanism.

A further object is to furnish a mechanism for this purpose, in which the articles are moved forwardly by a continuously moving endless belt made up of alternately arranged perforated feed sections, and imperforate blank sections; the articles to be boxed being deposited in the perforations of the feed sections, and being delivered by the latter into the cartons during intervals when the series of cartons is at rest.

In the Weber et al. Patent 1,l76,274 of December 4, 1923, a machine for this general purpose is disclosed, in which the articles are fed by means of intermittently moving fiat platesor plaques, and the present device differs mainly from the mechanism disclosed in the Weber et al. patent, by employing an endlessbelt in place of the flat plaques. In the improved belt construction made up of the perforated feed sections and imperforate blank sections, the intermittent movement of the line of cartons takes placewhile the imperforate sections of the, continuously moving belt are moved over thesame, and due to this construction, the mechanism much simpler,

and is cheaper and easier to run and maintain, and gives greater speed possibilities.

lVith the foregoing objects outlined, and with other objects in view which will appear 40 as the description proceeds, the invention consists in the novel features hereinafterde scribed in detail, illustrated in the. accompanying drawings, and more particularly pointed out in the appended claims.

Referring to the drawings:

Fig. 1 is a vertical longitudinal sectional view of the improved machine.

Fig.2 is a top plan view of the same.

Fig. 3 is an enlarged top plan View of a por tion of the feeding belt,illustrating the means for connecting the links or sections of'the .same. 7

ri'ed by shafts 5 and 6;

The shaft 6 is provided with 'a-gear 7, that is continuously rotated by a gear 8 on a shaft 9 whlch may, be continuously driven by any suitable mechanism. The shaft 9 and asilnilar shaft 10 are arranged below the table, and

they carry wheels 11 and 12 on which is and arranged above the table, and the articles to bepackaged move by gravity from this hopper on to the uppersurface of the upper I i run of the feed belt. As the latter move'sover the table 2, brushes 16, which maybe rocked by any suitable mechanism, cause'the arti cles to distribute themselves in the pockets 17 ofthe perforated sections or links 18 of the The table 2 is providedwith a transverse perforated-or screened portion 19 to permit any small particles breaking off of the articles, to fall through the table into a suitable receptacle 20.

Another brush 21 extends across the table above the belt, and may be rotated in a counter-clockwise direction by any suitable mechanism, for the'purpose of lnsurlngfilling of the pockets, and preventing any excess articles from riding on the upper surface of the belt.

A runway 23 is arranged at one en'dof the table and extends at right an les to the feed be filledfareinter belt, and the cartons to mittently fed along this runway by any suitable mechanism. a As before stated, the feed belt is continuously driven, and as one of its imperforate sections 18 comes over the runway 23,- the series of cartons in the runway will be moved forward one step, as the mechanism will be suitably timed to take care of such action. Then, while the cartons are at rest, one or more of the perforated sections of the belt may be moved over .the'same, so that the articles carried in the pockets of that section or those sections, may drop through into the cartons in the runway, which, of course, at this time are in alignment with the perforations of the belt. v

By the use of this mechanism, each carton may be gradually filled with lozenges or the like, while the cartons are intermittently moving along the runway 23. I For instance, when a carton is first halted beneath the upper run of the feed belt, the mechanism may be so timed that one or more articles are dropped into the carton. Then, while one of the blank or imperforate sections 18 of the feed belt is passing over the runway 23, the line of cartons may be shifted. Now, thecarton will receive one or more articles, and afterwards, the carton will again be shifted while an imperforate link of the belt is over the runway, and so on until the package is en tirely filled.

After the cartons are filled, they are preferably fed along the runway to a closing mechanism of the type shown in Patent No. 1,641,794, dated September 6, 1927.

As best shown in Figs. 3, and 4, the chain links have end flanges or cars 24, pivotally connected together by pins 25 carrying roller portions 26 which engage the teeth 27 ofthe sprocket wheels on which the feed belt is mounted.

Each link or section is preferably rectangu lar in plan, and is. provided on one side with the pivot ears, and its oppositeside, with parallel ribs 28;,the latter cooperating with the brushes 16 to facilitate the distribution of the, tablets or the like, into the apertures of the feed sections of the 'belt. The ridges or ribs 28 are spaced as shown to correspond with the width of the lozenges. V I

Each link or section of the belt is preferably formed of a metal casting, and I use metal wherever possible of the machme.

.From the foregoing it is believed that the in the remaining portions construction, operation and advantages of the invention may be readily understood, and it is apparent that changes may be made in the details disclosed without departing from the spirit of the invention as expressed in the following claims.

What is claimed and desired to be secured by Letters Patent, is:

1. In combination with an intermittent container moving mechanism, a continuously moving feed belt arranged at an angle thereto and comprising feed sections and blank sections, alternately arranged; the intermit-. tent container movements being timed to occur during the passing of each blank section, said feed sections having a series of alter nately aligned feed apertures adapted to register severally with a series of containers, when the latter are at rest, and successive intermittent movements of the latter being arranged to cumulatively load each of said containers. I

2. In combination with a runway support ing a series of intermittently moved cartons, of a continuously moving feed belt having one of its runs extending across said runway,

and comprising perforated feed sections and imperforate blank sections alternately arranged, the intermittent movements of the u cartons being tuned to occur during the pas- -sections permitting the passage therethrough of articles into said cartons, and the series of cartons being movable. along the runway while the blank sections of the feed belt are passingover said runway.

5. In'combination, a table, a runway associated with the table and supporting a series of intermittently moving cartons, a continuously moving feed belt slidable along said table and having one of its runs movable across said runway, means for depositing on one run of the belt, articles to be fed into said Y cartons, said belt comprising perforated feed sections and blank sections alternately arranged, the perforated sections being adapted to receive the articles and move them along thetable, and to finally drop them into the cartons, and the blank sections permitting movement of the series of cartons step by step between the feeding operations of the feed. sections. i

6. The combination with a runway supporting a series of intermittently moving 7. In combination, a runway supporting alternately arranged, said feed sections bean intermittently moving series of open caring provided With a series of transversely V tons, a continuously moving feed belt having alined perforations and all the sections being 1 one of its runs extending across said runway, provided With alined parallel ribs extending 5 means for depositing on said belt articles to between said perforations.
