To all whom z't may concern.'

Be it known that I, CLIFFORD G. Cizoon, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have in vented a new and useful Improvement in Machines for Packing Goods; and I do hereby declare the following to be a full, clear, and exact description thereof.

Myl invention relates to a machine for packing goods, and' has special reference to the packing of goods, such as candies in boxes, wherein goods of the same kind and shape, or goods of different kinds andshapes arle packed in boxes for 'shipment or for sa e.

Heretofore, in the packing of goods, such as candies, and particularly when it is desired to pack a large number of boxes at one time, the empty boxes are laid upon a table against each other, and then each of the packers hasy a large box or receptacle in his hands or in his arms or on his arms, with each containing different candies to be placed in such empty boxes. In this case,

the packers are required to walk around such table while picking out the candies from their boxes or receptacles, so that they can place the required amount or number' in each of the empty boxes, and thus a great deal of time was consumed in this process due to the packers interference with each other.

It was also very laborious for the packers on account of the walking and carrying which was necessary.

The object of my invention is to overcome these objections and diiculties by providing a cheap, simple and efficient machine for packing these goods, which will do away with carrying of the goods to be packed, will overcome the walking required, and will enable the goods to be packed in a much faster time.

A still further object of the invention is to provide such a machine on which the trays for carrying the different goods or candies to be packed will be capable of having dif'- ferent and intermittent speeds for the purpose of packing boxes of different sizes or quantities.

To these ends my invention consists, generally stated, in the novel machine for packing goods, as hereinafter more specifically set forth and described and particularly pointed out in the claims. p

To enable others skilled in the art to which my invention appertains to construct and use my improved machine for packing goods, I will describe the same more fully, referring to the accompanying drawings, in which:

Figure 1 is a side elevation of my improved machine for packing goods;

Fig. -2 is a sectional lan or top view of thesame, taken on the line 2 2 Fig. l, looking in the direction of the arrows;

Fig. 3 is an end View of the machine, taken on the line 3-3 Fig. l, looking in the direction of the arrows; Fig. 4 is a cross-section of the machine, on the line 4-4 Fig. 1 looking in the direction of the arrows;

Fig. 5 is a sectional view showing one of the power driven sprocket wheels employed and its operating lever, and taken on the line 5 5 Fig. 3;

Fig. 6 is a View showing a portion of the gearing mechanism;

Fig. 7 is a section of the gearing mechanism on the line 7-7 Fig. 3, looking in the direction of the arrows;

Fig. 8 is a View of the tray hanger;

Fig. 9 is an enlarged sectional View of the trays and carrying chain for same; and

4 Fig. l0 is an elevation of one of the trays.

Like symbols of reference indicate like parts in each of the figures of the drawings. As illustrated in the drawings, my improved machine is shown at A, and is formed from and supported by suitable frame work 1 built up from the floor a.

Within the frame 1 and on each side of the machine is a separate chain 2, which passes over sprocket wheels 3, 4 at each end of the machine and mounted on the shafts 5 and 6. The shaft 5 is mounted in suitable adjustable bearings 5 at lthe front end of the machine A and the shaft 6 is mounted in suitable bearings 6 at the rear end of the machine. chains 2 are the receiving trays 7, whichare pivotally connected to said chains through the hangers 8, such pivots being indicated at 9, and being at the upper ends of such hangers in order that the trays will have a swinging or tilting motion, but will always remain in a horizontal position for receiving and carrying the goods to be packed in the movement of the chains. The trays 7 will also be removable from'the hangers 8 Extending across between thev separa-ble and resting upon the removable ange portions 8' placed on ledges 8 on said hangers, and upwardly extendlng anges 7" are also formed on said portions to hold the goods to be packed on said trays, such portions and plates being held by said ledges resting on the same, with the portions resting in a seat 9 in said ledges. l

Mounted upon the floor a is a suitablemotor 10 which has a small pulley 11 mounted upon the main shaft 12 of the same and around which pulley and a larger pulley 13 mounted on the cross-shaft 14 a belt 15 passes. A small sprocket wheel 16 is also mounted on the shaft 14 and around such wheel and a larger sprocket wheel 16 on the cross shaft 17 a chain 18 passes. A sprocket wheel 19 is also mounted on the shaft 17 and around which and a larger sprocket 4wheel 2O on the cross-shaft 21 a chain 21 passes, which shaft 21 has suitable gearing mechanism, B connected therewith, as hereinafter described. l

Above the trays 7 and supported by the frame-work 1 is the storage bin or receptacle 22 for the elnpty boxes to be lled, which is provided with inwardly tapered open sides 23, formed of strips of wire cloth, and an opening 24 below each of the same, so that such boxes will-be directed to such openings and against the bottom`22 of said bin to enable them to be withdrawn through the openings when desired, as hereinafterl described.`

Extending along each side of the frame work 1 and exteriorly of the machine A is a bench 25, and under each of the same is a conveyer belt 26, which passes over'a pulley 27 at the front end of the machine and over a pulley 28 in a wrapping table 29, at the rear end of the machine. A supporting shelf 30 extends out from the frame-work 1 under the upper portion of the belt'26 to hold the same level and permit it to slide along the same, and a guard 30( extends out from such frame under the lower portion of such belt to keep the same from sagging down and interfering with the operatives. y

Mounted on the shaft 6 is the sprocketwheel 31 around which passes a sprocketchain 32, which also passes around a sprocket wheel 33 mounted on a shaft 34 carrying' the pulley 28, while an idler 35 mounted under the table 29 engages withf the bottom portion of the belt 26 to hold the same taut in passing over the pulleys 27 and,

28, and such belt through these connections is adapted to run at a slower rate of speed than the trays 7.

The gearing mechanism B is connected up with the shaft 21 and mounted upon one `side of the machine A, and upon said shaft 21 adjacent the sprocket wheel 20 is the sprocket wheel 36, and 'such wheels are of the same diameter, A chain 37 passes Mounted upon the shaft 21 -on the opposite side of the ,machine A from the wheels 2O and 36 is a gear wheel 41, which meshes with a larger gear wheel 42 mounted'on a shaft `43 above and in line with. the shaft 21, and mounted on said shaft 43 are the two gear wheels 44 and 45, which are of the 'same diameter, except that the wheel 44 is provided with only a toothed section 45 thereon for engagement with the gear wheel 46 when desired. This wheel 46 is movably mounted on a `shaft 47 whichis above and in line with the shaft 43 andsuch wheel is adapted to be moved along said shaft "47 by means of a yoked lever 48 engaging with a Y hub 49 on one sidey of the same. A gear wheel 50 is also mounted upon the shaft 47 and meshes with a smaller gear wheel 50' mounted upon the shaft 6 which is also above and inline with said shaft 47.

The use and operation of my improved machine for packing goods is as follows:

When the machlne A is placed in operation in any suitable'manner'by any suitable means, such asY the motor 10, acting through the shafts 12, 14, 17 21, 43, 47 and 6 will through the interposed connections betweenl the same, as previously described, operate,

ico

so that the conveyer formed by `the chains 2 and trays 7, as well as the belt 26 will travel in the direction of the arrows, shown in Fig. 2, The trays 7 being provided with the goods to be packed and the storage bin l22 provided with the empty boxes desired, such boxes can be packed in the following manner.

In the case -of mixed or assorted candies,

boxes or receptacles containing the same are placed upon the trays 7, with two ofthe same kind upon each tray, as described, and

the girls or other operatives are seated along each of the benches 25, so that as each operator pulls out an empty box from the bin 22 through the openings 24 and by holding the same in one hand or by placing the same on the bench 25, they can with the other hand pick the amount of candy desired from the receptacles passing along in the trays 7 in front of such operators. When the operatives have filled the boxes, they are then placed on the belts 26 which carry the same back into the table 29 where they are re` 'moved from the belts by the operatives seated around such table and the lids placed on thesame, after which they can be weighed l bythe operators around thetable 29, and

wrapped in the usual manner.

In case it is desired to change the speed of the moving trays 7, such as for instance, when larger boxes are, to be packed, the clutch 39 is so operated by the lever 40 to enga e with the sprocket wheel 20 and such wliee being connected by chain 2l and with the sprocket wheel 19 on the shaft 17, as pre- -viousl described, the shaft 21 is operated at a s ower speed than whenthelsprocket- Wheel was engaged by said clutch owing to the diiferences in sizes of the wheels 19 and 36. This slower movement of the shaft 21 will operate the shaft 6 through the gearing B at a slower speed and allows the operatives more time when packing largerr boxes.

When it is desired to pass still larger boxes and where several pieces are to be taken from the same receptacle on the trays 7 or from the said trays, an intermittent` drive is provided by theshifting of the gear 46 into engagement with the gear 44, at which time such gear 46 will be operated intermittently by reason of the toothed portion or segment 45 on said gear 44 and such trays will move forwardly along and then stop in front of the operatives for a predetermined period, so that the operatives may have sufiicient time to extract as many pieces as desired from such trays in the packmg of said larger boxes. e

It will thus be seen that by reason of the change inspeeds of shaft 2l and the continuous and intermittent gearing between shafts 43 and 47 in suc-h gearing B, variations of speeds, either continuous or intermittent, may be obtained.

It will also be seen that my improved method and machine for packing goods will enable the operatives to sit easily and comfortably around the machine and pack the goods quickly and easily, and thus overcome the laborious and irksome task of walking around a table carrying the goods to be packed.

It will further be seen that the goods to be packed will be within easy reach of theoperatives at all times and the empty boxes for packin will also be within reach, so that a continuous and steady packing of the goods can be kept up and maintained during the operation of packing and wrapping the goods.

V It will also be obvious that the operatives.

will be enabled to work faster and steadier without interference with each other in the packing of goods, and by reason of the arrangement of the device the operators are enabled to pack the goods fromA each of the trays in passing and each of the packed goods will be carried away from the machine ior weighing and wrapping. This arrangement of the device will also permit the trays to travel through the machine continuously and iny a horizontal position at all times, and they will not be liable to spill, drop or emgtg'A the goods to be packed which are carrie y them. l

It will be understood thaty my improved machine for packin goods may be used for the packing of goo other than candies or other like goods, and when used in connection with such goods, candies of different kind and shape and of the same shape and kind can be packed either by .being individually packed in the boxes from the trays or inbatches.'

Various modifications and changes in the design` and vconstruction of my improved mac ine may be resorted to without departing from the spirit of the invention or sacrifcin an of its advantages.
