To all whom t may concern Be it known that we, Ismon Z. GARFIELD, a citizen of the United States of America, residing in New York, borough of Manhattan, county and State of New York, and NATHAN GoLDrAR, a citizen of the United States of America, residing in New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Packaging Powders, of which the following is a specification. y

This invention relates to an improved machine for packaging powders, such as Seidlitz powders, Rochelle salts and similar powders for medicinal use, by which the powder is fed in accurately-measured quantities and in a temporarily compressed state to an intermittently -moving paper-band from which wrapper-blanks of the required size are cut, elo-sed by a double-fold atfthe sides and ends and then successively fed after the closed packages are subjected to pressure for crushing the cakes in the same to a delivery and counting mechanism whereby the manual work heretofore required for packaging such powders is dispensed with, and the same quickly and effectively packaged without loss of powder; and for this purpose the invention consists of an organized machine for packaging powders, which comprises means for measuring uniform quantities of the powder, compressing them into cakes and delivering them to a. continuous intermittently-movable paper-band below said compressing means. a folding mechanism for folding the sides of the wrappers into a double-fold over the cakes, means for cutting off the wrapperblanks from the continuous paper-band, and means for folding the ends of each wrapper on the body-portions of the same, and means for delivering and counting said packages.

The invention consists further of certain details of construction of the different cooperating parts of the machine, which will be first fully described and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a plan-view of the left-hand portion of our improved machine for packaging powders, Fig. 2 is a vertical longitudinal section on line Llf--LL Fig. 1, Fig. 3 is a plan-view of the right-hand portion of the machine, Figs. 4, 4:, 4b and 4 are vertical transverse sections showing the successive steps of side-folding the wrapping-paper over the cakes of powder fed to the continuous, intermittently-moving band, Figs. 5 and 6 show respectively, a side-elevation and a vertical transverse section, on line 6-6, Fig. 3, of the powder-measuring, cornpressing and delivering mechanism, Fig. 7 is a detail side-elevation of the lower portion of the feed-hopper showing the means for regulating the supply of powder to the compressing mechanism, Fig. 8 is a sideelevation of the left-hand end of the machine, showing tently-feeding the paper-band, the cutting off mechanism, and the mechanism for folding and closing the ends of the wrappers, Fig. 9 represents a vertical, transverse section with the mechanism for folding the ends of the wrappers over the bodypor tions of the same, and Figs. 10, 10b and 10 represent respectively perspective views and an end-view of the wrappers in the different stages of folding over and closing the ends of the same.

Similar letters of reference indicate corresponding parts throughout the several iigures of the drawings. y

Our organized machine for packaging medicinal powders by mechanical means into paper-wrappers consists of a machine for measuring the powders in uniform quantities and temporarily compressing them into cakes, and feeding them to a continuous paper-band which is intermittently moved forward below ing mechanism, a primary folder for creasing one side of the paper-band, a plurality of folders for doubling up and folding the sides of the paper-band, and intermittentlyactuated cutting mechanism for cutting off the side-folded paper-band into individual wrappers, means for folding over and closin the ends of the wrappers, and means for de ivering the packaged powders successively into a slidable tray for removing the same from the machine, and a counter for lthe mechanism for intermit-` the measuring and compress-I counting the number of packages delivered suitable medicinal powder, but preferably either sodium bi-carbonate or pulverized tartaric acid when the packages are made for Seidlitz powders which are usually wrapped into conventional blue and white paper. In. the hopper H is arranged about midway of its height a rotary agitato la, the arms ofwhicli keep the powder in motion, break up any lumps and prevent the clogging of the same. The stirrer-shaft h1 receives an intermittent rotary motion by suitable power-transmitting mechanism from the driving-shaft S of the machine. At the lower end of the hopper H yis ai'- ranged a box-shaped delivery-portion H1 in which is arranged a second transverse shaft'l which is preferably made of square shape at the inside of the box-shaped portion H1 and which is provided on each of its sides with brushes 71,3.' The brusli-shaft h2 receives like the stirrer-shaft h1 intermittent rotary motion so that the brushes are moved over a horizontal screen h4 which is supported on suitable cleats h5 at the bottom of the box-shaped portion H1 so as to feed a,

. delivery opening o in the bottom of the box.-

shaped portion H1. In the drawing, the drum D is arranged with six openings, but it is obvious that any other number of openings may be arranged in the same. The drum D is provided at each inlet-opening 01 with a stationary compressing cylinder l in which is located a piston d1 having a pis` toii-rod d2 which is guided in aii opening of the closed inner end of the cylinder d. Intermittent motion is imparted to the pistons d1 so as to produce first the compression of the measured off quantity of powder, next a forward motion for delivering the compressed cakes .onto a paper-wrapper, and then a return-motion for returning the pistons into their initial position for receiving the next quantity of powder through the feed-opening 0 in the lower box-shaped por-v tion of the hopper. The shape of the cylinder and pistons corresponds to the shape of the feed-openings o and o1; Each compressing cylinder (l is provided sidewise of the piston-rod d2 with a stop-screw (Z3 by which the inward adjustment of the piston is regulated and the same held in a ixed position when receiving the powder delivered to the cylinder. The positions of the stop-screws d1 are adjusted according to the quantity of powder which is to be delivered to the piston and the degree of compression to be imparted to the cakes. The quantity of powder to be delivered to each compressing cylinder of the drum D is furthermore regulated by raising the brush-shaft h1 into a somewhat higher or lower position in the box-shaped portion H1 by means of two exterior plates lz" located at opposite sides of the box-shaped portion H1, which plates are pivoted at one end of the side-wall of the vboxI-I1 and provided with bearings for the ends of the shaft k2. The shaft 11.2 is guided in slots o2 of the side-walls of the box-sliaped portion H1. The opposite end of each pivot-plate h6 is provided with an arcshaped recess if through which is passed a clamping-screw las, as shown in Fig. 7, for permitting the vertical adjustment of the plates h6 and shaft 11.2 and thereby the more eective feed-action of the brushes Ir* on the powder in the box-sliaped portion H1 and the delivery of a smaller or larger quantity of powder through the feed-openings o into the cylinder d then below the opening o. The adjusting plates are arranged at opposite sides of the box-shaped portion H1 so as to set thereby the shaft of thev feedbrushes at both 'ends slightly higher or lower relatively to the screen h1. The feed-brushes k3 force the powder with a variable pressure through the meshes-of the screen k* and feed after proper adjustment a uniform quantity of powder through the sani The exact quantity required is fed to each compressingcylinder of the drum D, after. brushes on the one hand and the pistons on the other hand are properly adjusted, so that these measuring devices operate with an accuracy equal to weighing devices. For some powders, especially for pulverized crystalline powder, such as tartaric acid, the screen can be dispensed with, as they are not liable to clog and move freely and easily under the pressure of the brushes to and through the feed-opening, while for impal- .pable powders, such as sodium bi-carbonate.

it is preferable to'use a screen and force the powder through the meshes of the same.

Intermittent rotary motion isimparted to the drum D and simultaneously to the shaft of the agitator and feed-brushes from the driving-shaft S by means of a pinion p on the same, which pinion meshes with a lgearwheel 7) that is mounted on a short intermediate shaft S said shaft being supported in journal-bearings of the supporting-frame. A wrist-pin p1 on the gear-wheel p is connected by a pivot-rod Q53 with a crank-arm p4 on a shaft S3 which is likewise supported in journal-bearings of the supporting-frame of the machine. On the shaft S3 is mounted a ratchet-wheel p5 which is provided with the feedas many teeth and recesses as there are eompressing-cylinders in the drum, the recesses of the ratchet-wheel being engaged by 'a spring-actuated pawl p on the outer end of the crank-arm p4 and by a check-pawl p. A second crank-arm 8 is mounted on the shaft S3 and connected y a pivot-rod p with a crank-arm p1" and by a pawl p at the end of the pivot-rod 9 with a ratchet-wheel p13 keyed to the shaflt S4 of the drum D, so that by the intermediate pawl and ratchet-wheel mechanisms and crank. connections, an intermittent rotary motion equal to 1/6th of the circumference of the drum is imparted to the same and thereby one compressing-cyl.- inder after the other fed into register with the' feed-opening in the bottom of the boxshaped hopper-portion H1. On the intermediate shaft S3 is mounted sidewise of the ratchet-wheel p5 a gear-wheel p15 which meshes with a pinion p on the short shaft p12 which is supported in bearings of the machine-frame. On the shaft p12 is keyed a sprocket-wheel p1 which transmits by a sprocket-chain p and wheel p18 intermittent rotary motion to the shaft h2. of the feed-brushes and by another sprocket-wheel and chain transmission p1 and p20 to the shaft h1 of the agitator h, as shown in Fig. 5. On the supporting-frame for the motiontransmitting mechanism is supported'an inclinedl block B, the concave face of which is concentric with the drum D and forms contact with the circumference -face of the drum, as shown in Figs. 5 and 6, and closes thereby throughout the rotation of the drum the opening o1 of the same which is at the time in register with the face of the block B. This block B serves to hold the charge of powder supplied to the openings o1 of the drum and to the cylinders d, while the inner ends of the pistons receive an outward motion by an intermediate mechanism, which is shown clearly in Fig. 5 and which consists of an oscillating lever b, which is fulcrumed to a fixed supporting arm b on the frame of the machine. The upper end of thearm b acts on the piston-rods of the cylinders while its outer slotted end is actuated by a connecting-rod b2, the upper end of which is pivoted to a wrist-pin b3 on a crank-disk b* placed on the shaft p12 of the sprocket wheel p1". By adjusting the lower end of the connecting-rod b2 nearer to or farther away Jfrom the'fulcrum of t-he oscillating bar b, the compression of the powder in the compressing cylinders of the drum D is regulated in proportion to' the greater or smaller degree of compactness to which it is to be compressed. This compression takes place when the drum D has completed onesixth part of its rotation which commences with Ythe registering of the first cylinder with the feed-opening of the hopper. When the drum is moved for 'the next one-sixth of its rotation, the compressed cake of powder is held 4Wit-hout any further action in its cylinder while at the end of the third onethe base-plate of the sixth part of the rotation of the cylinder the cake arrives at a point diametrically opposite to the feed-opening o and is delivered onto a wrapper placed below the drum on machine, by the action of a curved pusher e, which forms the upper arm of an elbow-lever e that is pivoted to a standard e2 attached to the base-plate of the machine. The elbow-lever e is connected at its apex by a pivot-rod e3 with the wrist-pin b3 on the crank-disk b* so as to be operated at the proper time whenever one ofthe compressing cylinders arrives at the end of the third one-sixth part of the rotation of the drum. The pusher e acts on the piston-rod (l2 and pushes the pistou d1 downward and delivers the cake from the cylinders to the wrapper. During the next one-sixth part of the rotation ot the drum D, the piston remains in its forward position in the cylinder, as sho-wn in Fig. 6, while after the fifth one-sixth part of the rotation of the drum D, the piston d# is returned into its normal position at the inside ofthe cylinder into contact with its stopscrew d3 by a pusher-lever f which isl fulcrumed to an upright standard f on the base of the supporting-frame, said pusherlever being provided with an a'rln f2 that extends inwardly into the cylinder so as to contact with the Apiston of the same and return the piston into its initial position ready to receive the next charge when the drum arrives at the end of the last one-sixth part of itsfrotation in register with the feedopening of the box-shaped portion H1. The lower end of the fulcrumed pusher-lever is connected by a pivot-rod f3 with the wristpin b3 on the crank-disk b4 so that the pusher-lever is actuated at each full rotation of the crank-disk. During the next rotation of the drum the same steps, namely. feeding the powder, compressing it into a cake, delivering it onto a wrapper, and returning the piston, are successively repeated for each rotation of the drum and as many cakes of powder delivered as there are compressing cylinders in the drum.

As some of the powder is carried along from the feed-opening o on the exterior surface of the drum D, as each cylinder passes beyond the feed-opening of the box-shaped portion H1, a scraper g is arranged in contact with the surface of the cylinder D, the upper end of the scraper being'attached to the end-wall of the box-shaped portion H1. By means of the scraper, any adhering powder is removed from the surface of the drum and delivered over 1the side-edges of the drum to a' suitable receptacle without being lconducted int-o the/narrow space between the compressing cylinders (Z and the compressing block B so that not the slightest increase in the quantity of powder in the compression-space between the cylinder and moved forward over its -block can take place. At one side of the hopper H is arranged a spring-actuated knocker 7L", the spring-arm of which is actuated by the sprocket-wheel on the shaft 71,2. The blows of the knocker on the lower part of the hopper shake up the powder and deliver it freely to the feed-brushes.

The measuring and compressing machine forms the subject-matter of a separate application led by Isidor Z. Garfield on March 13,1912, ser. No. 683,522. Y It is obvious that any other measuring and compressing mechanism for delivering cakes of uniform weight and round or other shape may be employed.

The feeding and side-folding mechanism 0f the paperbamd-The paper is supplied wrappers required for the packages. The

^\ tent feed of the temporarily-compressed cakes are dropped at the required equal distances fromeach other on the intermittently-movable paperband so that a sufficient space is left between the cakes to bring them into the center of the wrapper-blanks. The intermitpaper-band is imparted from the shaft S of the gear-wheel 7) to avv shaft S which is connected by a universal joint y' with the shaft S and by another universal joint j with a horizontal shaftv S6 which turns in suitable bearings of a separate vsupporting-frame F for the left-hand end of the machine and which supplies the required power for the intermittent feeding of the paper-band over Vthe supporting guide-plate F that extends from the compressing drum to the frame F, also the lpower foractuating the cutting oil", endfolding, delivering and counting mechanisms. The frame F is connected with the frame of the compressing machine by longitudinal parallel bars F2. On the right-hand end of the shaft S is mounted a wormwheel fw which meshes with a second worm- .wheel rw of equal size, which is located at right langles to the worm-wheel fw below the same and the shaft 'w2 of which is supported inl bracket-bearings of the frame F for'` transmitting by acrank-rod m4 connected with a wrist-pin w3 on the wormwheel 'w' oscillating motion to lever 105,' which is pivoted at its lower end to a crossbar F2 of the frameF andv which is pivotally connected at its upper end vwith a reciprocating carriage we, guided on ways 107 ofthe frame F. In ears at the upper frontend of the reciprocating carriage w-6 is supported a lateral pivot-shaft w8 which expawl 102, that is pressed and 4 respectively,

tends over the side-folded paper-band and which carries a downwardly projecting feedin downward direction during the forward motion of the carriage by a spring-finger w1 which presses on the upper curved edge of the feed-pawl, as shown in Figs. land 8. The wormwheel transmission is so proportioned that for each rotation ofthe gear-wheel p and shaft S2, an oscillating forward and backward motion is imparted to the lever 'w5 so that it moves at each forward motion by the engagement of the sharp edge of the Apawl w the paper-band forward immediately after a cake o f powder has been delivered bythecompressing drum on the same. The biting action of the pawl and the forward feeding of the paper-band takes place during theoscillating motion of the lever lw5 toward the left, while by the return-motion of the level-fw5 toward the right the feed-pawl is moved freely in backward direction over the paper-band ready for the next feed-motion of the pawl. A transverse bar fwn onfthe reciprocating carriage lw extends over the paper-band adjacent to the feed-pawl wg, as shown in Fig. 1, and holds thereby the paper-band in position for bveing fed'by th'elfeed-pawl over its supporting guide-plate F toward the end-,folding mechanism at the vleft-hand end of the machine.

By the forward movement of the paperband over its supporting guide-plate F, there is firstformed at one edge by an inclined folder z', -and creaser which are arranged on the Aleft-hand side of the lguideplate F near the compressing drum, a narrow creased edge-strip Z, as shown in Fig. 4. Thezfolder z' bends over the edge l and the creaser 2'. being smaller in size than the folder z', produces the. crease-line in the paper-band. 'Simultaneously therewith the left-hand side of the paper-band is folded over thecakes toward the right-hand side of the, same, as shown in Fig. 42. The creased edge-'strip `Z serves to contact with the paper-band land serves to hold the foldportion in a l slightly-curved poSied-Over tion, inthe nature of'a loose bight so that pressure on the cakes' is prevented and the same carried along with the pa er-band until the paper-band is doubleolded at its right-hand side. The double side-folding of the paper-band is accomplished gradually by the successive action of the turnover folders, 2, i3, z", which are arranged on the right-hand side of .the guide-plate F, as shown in Fig. 1. The folders 2, 712,'4

-fold the right-hand side of the paper-band' over the creased strip, asI shown at l and then fold it with thev creased strip into a double fold Z2; as shown in the Figs. 43,4",

so that when the paperband arrives 'near the feed-pawlit is closed by the double fold. During the side folding of the paper-band, the folded portion is held on the guide-plate by suitable cross-strips. After the side-'folded paper-band has'passed beyond the feed-pawl, it is cut off mldway between the cakes delivered thereto by a fulcrumed cutting device C which consists of a stationary knife 7c and an oscillating and vertically reciprocating knife k,'which latter is operated by means of a downwardlyextending cam 7a2 on the shaft S3, said cam engaging a pin 7c3 at the lower end of a pivoted arm la* which is held 'by a spring lo in contact with the cam 7a2 while the cutting operation takes place. The portion of the side-folded paper-band, which has been moved past the cutting-device into the endfoldingmechanism is thus cut of and forms the wrapper proper, which is then folded at the ends and moved forward for delivery.

The end-folding mechanism.-The sidefolded wrapper containing the cake is next taken up by the end-folding mechanism and moved through an angle of 90 from its horizontal osition into a vertical `position by anV oscil ating plate or platform a of the end-closing mechanism. The platform n is hinged at its inner end and connected at the underside of its forward end with an actuating cnecting-rod n', the lower end of which is connected by an anti-friction roller n2 with the cam-groove of a cam n3 on the shaft SG. Each rotation of the shaft S6 imparts an up and down tilting motion to the platform n and moves thereby the wrapper into vertical position along stationary sidewalls n* by which the wrapper-ends are bent over at right angles to the body-portion of the wrapper Z3, as shown in dotted lines in Fig. 10a and in full lines in Fig. 10b. During the upwardly-tilting motion of the wrapper, it is passed along by a spring-finger a5. In this position the rectangularly bent-over ends of the wrapper are acted upon by laterally-oscillating lingers a6 which fold the bent-up ends of the wrapper over on the body-portion of the' same, as shown in Fig.

10c. The motion of the fingers a is accomplished by means of fulcrumed levers a7 which are pivoted at their upper ends to the lower ends of the fingers 'n.6 and at their lower slotted ends to a pin on the cam-rod fn. of' the platform, so that during the upward motion of the cam-rod n the fingers are moved outwardly and during the downward motion of the platform inwardly for folding the ends of the wrappers over the body-portion of the same. lThe end-folded wrapper is next pushed forward by the next following end-folded wrapper over curved guide-fingers n into the ad]acent end 1"` of a delivery-channel r. The connecting-end r of the delivery channel 7' is curved in the form of a quadrant of a circle while the main-portion is straight and arranged parallel with and alongside of the supporting guide-plate for the paper-band, as shown in Fig. 1. A second spring-actuated finger Va extends over the upper edge of the raised. wrappers so as to hold them in proper position for being pushed forward lnto the curved portion of the delivery-channel r. The upper edges of the'wrappers are thenl passed under a stationary angular uide-arm 11.1 and then forward between e curved side-walls of'the delivery-channel into the straight main-portion of the same.

Alongside of the curved end-portion 1" of the delivery-channel 'r is arranged an intermittently-rotated disk 'n.11 which is provided with pins no on its face that are engaged by a spring-pawl 11,12 which is operated lby means of a spring-actuated connecting-rod n having an anti-friction roller n at its lower end. The roller 'n.14 engages a cam n at the outermost end of the shaft S so. that the disk n is turned for one twelfth part of its rotation on every rotation of the shaft S6. For this purpose the disk nu is provided with twelve teeth or pins on its face. Y 0n the circumference of the disk 'nu is arranged in radial alinement with one of the pins, a longer tooth n which engages the downwardly-extending arm- 1t" of a rocking-lever a and produces the lifting of the longer arm of the rocln'ng-lever a that enters through a slot in the side-wall of the curved portion of the delivery-channel rA and the raisin of every twelfth wrapper into a diagonal y inclined position, as shown in Fig. 2, so as to separate thereby the wrappers into dozens for the convenient packing into boxes for shipment. The wrappers are pushed forward along the curved portion of the delivery-ch annel into the straight portion, while the inclined separating wrappers are guided along the upper edge of the outer side-wall of the delivery-channel 1'.

In place of dividing the wrappers into groups of one dozen each, they may be di-- vided into groups of ten wrappers, in which case, however, the actuating disk for the rocking-lever is to be provided with ten instead of twelve teeth.

By the pressure exerted on the package during the folding over of the ends of the wrappers and by the forcible forward pushinv of the same into the delivery-channel a sultlicient pressure is exerted on the bodyportion of the wrappers for crushing the cakes in the same and changing them back into powder-form so that flat wrappers of the usual shape are obtained. l

The delivery mechanism- The delivery mechanism consists of the delivery-channel r, a plate r2v which is located in and guided,y

by the side-walls of the channel 1', and a. t.

delivery-tray ravwhich is placed in the channel .and pushed under the plate r2. To the delivery-plate r2 a horizontally-reciprocat- 'every inclined twelfth package.

ing motion is imparted by means of a transverse rod T4 which is attached to the upper slotted end of the oscillating lever wf and which serves to engage one or the other oi' two downwardly-extending pins T5 on the ingoing end of the delivery-plate T2, as shown in Figs.v l and 2. The pins T5 pass through slots T6 in the bottom of the delivery-channel T. The delivery-plate T2 is provided at opposite sides with fiat crimped-up inclined teeth T'r which during the left-hand motion of the delivery-plate are moved un-4 der the'lower edges of the wrappers fed to the same from the curved portion T of the delivery-channel and then carried along by the motion of the delivery-plate T2 toward the right over toward and on a delivery-tray T3 until the same is entirely filled up with Wrappers divided into groups of twelve by The fiat teeth of the delivery-plate T2 gradually push the wrappers forward so that the same do not exert any backward pressure on the wrappers in the curved portion T and the end-folding mechanism. When the delivery-tray T3 is gradually filled up with wrappers, it is removed and a'new tray placed in position under the reciprocating delivery- 'the combination, with a combined measurf ing and compressing device for the powder, 'of means for delivering the cakes formed plate to be lled again with wrappers delivered by 'the delivery-plate. Simultaneously with the oscillating mot-ion of the lever lw, a counter D is operated by an oscillating connecting-rod u which` is pivoted to -the reciprocation, rod T'i at one end and connected with a crank u on the countershaft at its opposite slotted end by a pin u2 so that the shaft of the counter is operated whenever the connecting-rod u arrives at the end of its motion.' The counter serves for counting the total nu ueber of wrappers made and delivered by the machine within a given time.

The machine is mainly intended for packaging- Seidlitz-powders, but it is obvious that any other powders which 'are to be packed into wrap ers closed-at the sides and ends,- can be pac ed by the same, without loss or waste, which is mainly due to the temporary compressionl ofthe powder into cakes, which cakes are afterward, by the end-folding of the wrappers and the pressure exerted thereon, crushed and changed into powder-form, the temporary compression of the powderA into cakes serving only for the purpose of preventing loss of material and from the wrappers during the folding operations and during the transmission of the wrappers from the measuring and compressing mechanisms to the end-folding.
