PACKING-TABLE.

Specification of Letters Patent.

Application filed pctober 31, 1911. Serial No. 657,848.

To all whom it may concern:

Be it known that we, ALONZO'LINTON BAUSMAN and DANIEL C. COTTREAL, both citizens of the United States of America, residing at Chicopee and Springfield,- respectively, in the county of Hampden and State of Massachusetts, have jointly invented new and useful Improvements in Packing-Tables, of which the following is a specification.

This invention relates to a packing table of a kind particularly useful to aid in packing candy.

- The structure embodied in this invention may be used for many purposes besides the particular one referred to.

In packing assorted candies and the like, the common method is for each packer to kinds of candy in regular rotation from a suitable receptacle which contains the candies in certain definite proportions. It is-desirable for the manufacturer to have his product uniform, and heretofore there has been much trouble because the packers can not be depended upon kinds of candy in the proper way. Some kinds of candy intended for the mixture in each box would be slighted andafter the packers have been working several hours atthe usual method of packing, it has been found that the'prodnot in each box is not the kind of a mixture desired. The result is clearly undesirable, not only as to the'product but also because the manufacturer can not definitely determine just how much candy of each grade he can safely make up to yield a. given number of boxes with the proper proportion of each grade in the mixture.

It is the object of this invention toavoid the difliculties referred to in packing assorted candies.

Another object of the invention is to provide a structure which will require the packers to work at a uniform speed and'which will afford a means of checking up the work If any packer neglects to of the packers.

the required rate of work. this fact will immediately be apparent.

Other objects of the invention will appear in the detailed description of the invent-ion and in the claims.

In the drawings forming part of this applicatiom-Figure 1 is'a top plan view of each tray, so that, as can the apparatus. view taken on the line 2-2 of Fig. '1 looking in the direction of the arrow. Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1. Fig. 4 is an end view of the apparatus assembled. Fig. 5 is an enlarged view of the mechanism directly involved for transferring the trays on the outward travel of the endless chain to the inward travel.

The apparatus comprises, among other things, a device operated to carry a series of trays along beside a stationary table by an endless chain. The trays are adapted, with suitable mechanism, to contain articles to be packed andalways to remain with one side up while traveling around with an endless chain.

Referring to the drawings in detail, a is a motor adapted to drive the sprocket wheels 0 suitably mounted through the gear connections, clearly shown in Figs. 2 and 4. The wheels 0, together with sprocket-wheels (Z. carry endless chains 6, (one on each side of the apparatus) which are adapted to operate any desired number of trays. The trays a Z2 0 etc., are provided with front and rear rollers, as shown, which are supported on the tracks g, best seen in Fig. 3. The front rollers have their axles extended to cooperate with the bearings q carried by the chain (see Fig. 5). These front rollers to this extent differ from the rear rollers of be seen from the the rear rollers, when they leave (Fig. 2) can be carried, togethler t 1c drawing, the track 9 with the rear end of the tray, between two endless chains shown, the lowertrack g (the tracks being mounted suitably, as shown in the frame) by mechanism now to be described.

On the shaft r is a sprocket-wheel (see Fig. 5) which, together with a wheel mounted on the shaft m in the frame, carries a chain. This chain transmits motion from the driving shaft to the sprocket-wheels loosely mounted on the bearing shaft on.

Itis to be understood, as is clear from Fig. at of the drawings, that each sideof the apparatus is similar and the side opposite that shown in Fig. 5 has the identical arrangement of mechanism as that shown in Fig. 5. I

The shaft on has mounted fast thereon a cam which operates on two levers a pivot- Patented Apr.-9, 1912.

the arm 0 to grip the extending pins k of the rollers at the rear of each. tray, and thus hold the rear of each tray as it leaves the upper track 9 until that end of the tray has been placed on the lower track 9 in a way to be later described.

The mechanism-by which the trays are transferred from the lower track to. the upper one is shown best in Fig. 2 and differs in certain respects from the mechanism just The shaft p is mounted in the frame. outside the space inclosed by the chain c. A chain-gear connection, as shown, transmits motion from the'wheel d to the shaft p. It will be noticed that the front ends of the trays on their outward passage are the rear ends on their rearward pas-1 The shaft p has sage, and vice versa. mounted thereon an arm 8 similar to the arm 0 on the shaft m but differing therefrom in that there are no levers n, n mounted thereon. A semi-circular track 7:. cooperates with the arm 8 to pass the ends of the trays from the lower to the upper track. The arm 8,

as shown, has slots provided in its ends to cooperate with thepins of the rollers not fastened to the chain e.

- k, the cam, which is desi The operation of the apparatus, so far described, is as follows: The tray 0 is pulled along the upper track b the endless chains. When the forward en of the tray reaches the circumference of the wheel a and is about to pass from the outward to the" rearwardatravel of the chains, the slots the arms 0, one on each side of the apparatus, engage the pins 7: of the rear rollers. The shaft m is so geared to the shaft 0" and the trays are so placed along the chains that the engagement of the pins is will take place at exactly the right moment. At the'same time that the slots 1 cooperate with the pins ed for the purpose, will force the hooke ends of the pivotally mounted levers n around the pins to hold them securely in the slots. The cam is designed so that the hooked ends of the levers will release the pins only after the arm 0 in its rotation has carried the rear end of the tray from the top track 9 to the bottom track 9.

As can be easily drawings, the passage of the tray from the top to the bottom track takes place without turnin the tray over. The same side of, the tray remains the upper side at all times. As may also be seen from the drawing, the rear rollers of the tra are kept on a substantially horizontal ine with the front seen from Fig. 5 .of the continually the apparatus is designed so thatrollers so that the tray in its passage .notonly remains with the same side up bu also remainslevel. The operation of this art of the apparatus may be seen so clearly from the drawings that more detailed description is thought to be unnecessary.

When a tray passes from the bottom to the top track, the slots in the arm s engage the pins is (see Fig. 2) and the rotation of the arm forces the rollers around the track k while the rollers fastened to the chain pass around the wheel and keep the tray on a horizontal line: The small track g afi'ords. a bridge for supporting the rear rollers for the passage from the releasing position of the arm 8 to the track g.

From the operation described and from :the' drawings itcan be-seen that the trays pass around the cycle of operations with the same side always up and always level. It may be also seen that the arms 11. and s are operating with the trays. As the arms finish with one 'tray by releasing it from one end for its passage along the track the opposite ends engage the next succeeding tray to aid in its transfer from track to track. All the available space for the trays carried by the endless chains, which it is possible to use, is used.

The apparatus is used for packing as follows: The packers sit on each side of the table 2' (Fig. 1). The trays, in their travel, passalong between the packers, each tray having a certain kind and numberof pieces of candy, or other .article to be packed, the kinds in each tray usually differing from the other trays. The number of pieces in each tray is determined by the number of packers working. These pieces, in proper-number, aree placed'son eachatray by an operator sitting at the end A; As each tray passes a packer, that packer must take the proper number of pieces therefrom and as the tray is traveling at a uniform. speed past each packer, the speed of packing is regulated. If any the proper share from each tray then the tray will return to the operator at'the end packer neglects to take A still containing one or more ofthe articles to be packed. A check is thus obtained on the work ofthe packers which immediately gives notice when the packing is not progressing as desired. Where notice is given as soon as trouble arises, the trouble can be easily located and the mixture of the goods packed be kept uniform.

The results obtained from the apparatus described are,. increased attention to the wor on the part of the packers, and a meansof insuring the uniformity of ackages, such as mixed chocolates and the like.

The apparatus may be used for any purpose where it is desired to pass containers around with an endless belt while keeping them uniformly level and right side up.
