LUDWIG NEUMAYER, OF MERSEBURG, GERMANY.

DIVIDER AND BAG-FILLER FOR POWDERS.

' SPECIFICATION forming part of Letters Patent No. 678,272, dated July 9, 1901. Application filed May 25, 1900. Serial No. 17,940- (No model.)

T0 all whom it may concern.-

Be it known that I, LUDWIG NEUMAYER, a subject of the German Emperor, and a resident of Merseburg, Germany, have invented certain new and useful Improvements in Devices for Dividing'Pulverulent Masses into Equal Parts and Filling Same into Paper Bags, of which the following is a specification.

The object of my present invention is to provide a device whereby a given quantity of pulverulent ware is mechanically divided into any desired number of equal parts and then filled into a corresponding number of paper bags or other receptacles.

The invention consists of a case serving to receive the pulverulent ware to be divided and filled into bags, &c., a divider, a second case serving to receive the filled bags, and a device-for shaking and reversing the dividing and filling cases.

In the accompanying drawings, Figure 1 is a vertical section, Fig. 2 a top plan view, and Fig. 3 a side elevation, of the case a, serving to receive the pulverulent ware to be divided into equal parts and then filled into paper bags, &e.; Figs. 4, 5, and 6, details in side elevation, top plan, and transverse section,

respectively, of the adjustable evener for spreading the material uniformly in case a; Fig. 7, a bottom plan view of the divider; Fig. 8, a vertical section thereof on line say of Fig. 7, and Fig. 9 a top plan view of said divider. Fig. 10 is a vertical section, and Fig. 11 a top plan view, of the case serving to receive the filled bags, in the latter view with its sides opened flatwise; Figs. 12 and 13, respectively,a side elevation and a top plan view of the skeleton frame or basket for holding together the bottom and side walls of the case last above mentioned; Fig. 14, a detail illustrating the operation of the evener in connection with case a and its contents; Fig. 15, a

transverse section showing the case a with its contents and the divider introduced therein, with the bag-holding case on top thereof and the skeleton side and bottom holding frame thereover; Fig. 16, a corresponding view of said parts inverted to permit the contents of case ato run into the bags held by the other case. Fig. 17 is afront elevation, and Fig. 18

is made square in cross-section a side elevation, of the apparatus for shaking and inverting the cases in operation.

' The case a. is provided with handles 19 and has its upper edges reinforced by means of angle-irons or equivalents c. The inner faces of the case are lined with suitable material, such as sheet metal, &c.

Thedivider is formed of a number of sockets made of equal sizes and one end of which Said sockets are assembled so that they form a rigid deviee adapted to be snugly fitted into the case a. The end opposite to the square section of each socket is made circular in cross-section. The outer sockets are surrounded by a frame "5, which serves at the same time to support said sockets when it is laid upon the upper edges 0 of the case a and to prevent the diivider from falling out of the latter when the operator reverses the device, as hereinafter explained. The case is, serving to receive the filled bags, is formed of a fiat bottom, to which are hinged the four side walls by means of hinges I. Said walls are provided with slidable parts 41, provided with slots n, through which extend guide-pins secured to the walls, and the nuts m of which serve to lock said slidable parts on the Walls of the case 7 0, so that the height of the latter may be made corresponding to the height of the paper bags employed in each particular case. The bottom and side walls of the case are held together by means of an outer case or basket. outer case is formed of a frame 0 and two crossing stirrups p,-secured thereto, andprovided with handles q for easily manipulating the case, which fits snugly over the case k, so that the latter is then held in closed position.

The device so far described is manipulated as follows: The pulverulent ware to be divided into equal parts and filled into bags is poured into the case a and uniformly spread out over the bottom thereof by means of any suitable devicefor instance, by means of the device shown in Figs. 4 to 6. Referring to these figures, d'represents a wooden bar, the under side of which is covered with a metal band h. f f indicate threaded guidepins secured to the side of said bar and ex- (Shown in Figs. 12 and 13.) This 4 tom of the case a, the frame t' of the dividerresting then on the upper edges 0 of the case (i Now the paper bags or other receptacles.

are fitted over the sockets of the divider, and

over the latter is finally fitted the second case 3 7a. In order to prevent the bags fitted over the extreme sockets of the divider from being mutilated between the edges of the cases a: and k, the walls of the case 70 are movably connected to the bottom of the latter, as al- .1 ready described, so that said walls are brought;

case k, whereby the device is in the position shown in Fig. 15. Now when the device is turned over or inverted by means of the handles b q the pulverulent ware drops through the sockets into the paper bags, Fig. 16. After removing the case a and the divider the filled paper bags are arranged in the case It.

It will be seen that the several cases or the whole device must be somewhat shaken inf operation in order to facilitate the passage ofi the pulverulent mass from one receptacle To this end and for the purpose of easily reversing or inverting the cases, I have provided the device shown in Figs. 17-

Each of said bearings is pressed upwardly by the action of a coiled spring at and may be lowered by depressing a 1 treadle 5, connected to said bearings by: After releasing the treadle the bearings are rapidly raised by the action of the springs 4 4, t In order to means of chains 6 and connecting-rods 7.

the end of one of the studs 0 is provided with,

a slit or groove engaged by a spring-actuated lever 8, so that the case may be maintained in either an upright or inverted position. To

the case a is suitably secured the case it, the

walls of which are held together by means of the stirrups 1), provided with the handles q q, already described. In order to prevent the case 70 from falling down after loosening its connection with the case a, I have arranged between the lateral frames 3 3 a platform 9, guided in vertical slots provided in said frames and adapted to be raised and lowered by means of a weighted lever 10, alever-arm shaken.

Then the skeleton shown in Figs. 12 and 13 is fitted over the 11, and guide-rods 12 13. To lock the skeleton p to the case a, slotted hasps 14 are hinged to said skeleton, and upon the case a are arranged brackets 15, in which work thumbscrews 16,en gagin g the screw-threaded shanks of hooks 17 to draw them down into the slots of the hasps, and thereby secure said hasps. The operation of the device is as follows: After filling the case aand securing the case 70 thereto said cases are rotated on the studs, so that the case 70 is suspended under the case a. By depressing the treadle 5 and at terward releasing same the cases are strongly Then the platform 9 is raised under the bottom of the case 70 by depressing the weighted lever 10, whereupon the connections between the cases aand k are loosened, whereby the case 70 may be removed laterally. The socket-divider is not shown in Figs. 17 and 18; but the operation may be readily understood without showing said divider. It is evident that the springs serving to shake the cases may be dispensed with and cams or equivalents substituted therefor. Again, the platform 9 may be raised and lowered by means of other devices, such as rack-andpinion mechanism, and the whole device may be operated by hand or any suitable power.

Having fully described my invention, what I I claim, and desire to secure by Letters Patent, is
