SPECIFICATION forming part of Letters Patent No. 716,007, dated December 16, 1902.

Application filed March 26, 1902.

T0 (0 whom, it may concern:

Be it known that 1, WILLIAM H. DOBLE, a citizen of the United States, and a resident of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Packaging-Machines, of which the following is a specification.

There are certain kinds of goodssuch' as spice, flour, baking-powder, and other fine fluffy goods-which if fed loosely into a pack age will occupy much more space and require a larger package than if packed closely, and if put up in a package large enough to contain the desired quantity when loose there will be too much space after the package has been handled about, so that the goods will shake around in the package. Besides, itis otherwise an advantage to have the packages as compact as possible. 'When the packages consist of cartons or other packages of flexible material with which it is not so desirable to employ tappers to settle the goods, it is advantageous to employ means for pressing the goods into the package while filling. In such case if the package is not of rigid material it is desi rable to have a holder to retain the package in' proper form.

The main objects of the present invention are to provide means for pressing the goods into the package while being filled and to retain the packages in form. Other features of the invention will be set forth in the specification.

The invention will now be fully described by reference to the accompanying drawings, and the novel features will be particularly pointed out in the claims at the close of the specification.

In the drawings, Figure l is a front elevation of a machine embodying the invention. Fig. 2 is a side elevation viewed from the right-hand side of Fig. 1. Fig. 3 is an enlarged detail of a portion of Fig. 2, showing the feed and the mechanism for handling the carton. Fig. 4 is a detail plan of the cartonholder. Fig. 5 is a detail plan showing the carton-holder and the connecting mechanism for controlling the movement of the carrier. Fig. 6 is an end elevation of Fig. 5, partly Serial No. 100,059. (No model.)

sectioned, on line 6 6 of Fig. 5. Fig. 7 is a detail of the wedge which actuates the clutchengaging mechanism for starting the carrier. Fig. 8 is an enlarged detail of the sleeve and sliding bolt on the rocker-shaft. Fig. 9 is an enlarged detail elevation showing the clutch and some of the connections for driving and stopping the package-carrying ring. Fig. 10 is an enlarged detail showing the same parts as in Fig. 8 and in addition thereto the stop 57, with which the bolt engages. Fig. 11 is a plan of the machine, the worm-feed hopper and overhead mechanism being omitted. Fig. 12 is a vertical section on line 12 12 of Fig. 11. Fig. 13 is a detail elevation at the rear of the machine, showing the cam-lever which is engaged by one of the package-carrier fingers and the connections for actuating the rocker-shaft to open the scale-hopper valve. Fig. 14 is a detail, partly in section, on line 14 14 of Fig. 13.

Referring now to the drawings, 1 represents a hopper through which goods are fed to provide the packages with a preliminary supply of goods, and 2 represents the scalehopper, through which the package receives the completion of its load.

3 is a rotary ring-carrier provided with fingers 4, which move the packages along a track 5 from beneath the preliminary feedhopper 1 to the scale-hopper 2. When the scale tips, a reciprocating member 6 is caused to move in a direction to close the scale-hopper feed. The carrier-ring 3 is driven by pinion 81 on shaft 9, and shaft 9 is connected by clutch 41 and bevel- gears 87 and 140 with a shaft 141. The lower member of clutch 41 is fast to shaft 9, and the shell 85 is fast to the hub of bevel-gear 87, but loose on shaft 9. In the inner periphery of shell 85 are a series of scalloped recesses 94, adapted to be engaged by a pawl or cam 86 on the upper end of shaft 93 to lock the two members of the clutch together, and when so locked the shaft 9 will revolve and move the carrier-ring 3. A spring 88 tends to hold the cam 86 thus engaged. On the lower end of cam-shaft 93 is a dog 83, which when the reciprocating frame 6 is in its rearward position and the hopper-valve open is engaged by a stop-lever in a manner to hold the cam-shaft 93 turned so that the cam 86 will be out of engagement with any of the recesses 94 and the shaft 9 will not turn. When the reciprocating frame 6 moves forward to close the hopper-valve, the projection 42 on the side of the frame will, by its engagement with wedge-arm 46 and engagement of arm 46 with arm 43, push the sliding pin 7 to the left as viewed in Fig. 9, thereby causing the boss 95, which is carried by the pin 7 and is in engagement with arm 96 of stop-lever 80, to turn stop-lever 80 on its pivot 99 and disengage the stop-lever from the dog 83, thereby allowing spring 88 to throw cam 86 into engagement with one of the recesses in shell 85, and the pinion 81 is caused to revolve and move the carrier-ring 3.

Carried on shaft 9 is an eccentric cam 84, which when said shaft has partially completed a revolution will, by its engagement with arm 82, projecting from sliding pin 7, turn said pin 7 on its axis far enough to turn arm 43 down out of engagement with wedge-arm 46, and spring 8, which was compressed when the pin 7 was pushed by the sliding frame, will expand and push said pin in the reverse direction back into the position shown in Figs. 5 and 9, bringing stop-lever 80 down into position' to again intercept the dog 83 at the end of the revolution of shaft 9. When the dog 83 is thus intercepted,the two members of the clutch will be disengaged and the rotation of pinion 81 and carrier-ring 3 will be stopped, the pinion 81 having made one complete revolution. After the eccentric cam 84 has moved around far enough for the stop-lever 80 to drop down into its intercepting position, the cam will before the end of its revolution permit spring 8 to turn pin 7 on its axis, so as to bring arm 43 back into the position shown in Figs. 5 and 9, ready to he engaged by wedgearm 46 at the next feed-valve-closing movement of the reciprocating frame, the wedgearm 46 having been turned down out of its engaging position, as will be hereinafter described, so that arm 43 may be brought up into position.

There are various forms of mechanisms by which the scale hopper or valve may be closed and the carrier-ring actuated by the tipping of the scale-beam and the valve opened again when a package is brought to the scale. One form of mechanism for doing this is shown in Patent No. 633,253, dated September 19, 1899, to G. W. Watson, and another form is shown in Patent No. 556,231, dated March 10, 1896.

The mechanism shown in the drawings for actuating the reciprocating frame and scalehopper valve is operated by compressed air and will now be described; but it forms in part the subject of another application, and it is not intended to limit the scope of the claims herein to the use of the form of mechanism shown for actuating the scale-hopper valve or to the use of compressed air as a power.

In one end of cylinder 100 is a piston 101,

whose stem is connected with the cross-head 102 of the reciprocating frame 6, and in the other end of said cylinder is a piston 103, whose stem is connected with cross-head 104. The two cross-heads are connected together by side rods 105, which slide through brackets fixed to the side of cylinder 100 and, to gether with the pistons 101 103, compose what is herein referred to as the reciprocating frame 6. A bushing 106 passes crosswise through an air-chest 107 in cylinder 100 between the two pistons 101 and 103 and forms a casing for the piston-valve 118, which is connected by rod 108 and crank 109 with rockershaft 110, the valve 118 being moved up and down by the rocking of said shaft. The airchest 107 is cored out to form ring air-chambers 111 112 113, each of said chambers having ports leading through the bushing 106. A duct 114 leads from the lower ring-chamber 113 into the cylinder-chamber 115, in which the piston 101 moves, and a duct 116 leads from the upper ring-chamber 111 into the cylinder-chamber 117, in which the piston 103 moves. The middle ring-chamber 112 is connected with a compressed-air chamber or pump. The rising and falling of the pistonvalve 118 admits pressure alternately to the cylinder-chambers 115 and 117, and thereby drives the pistons 101 and 103 and moves the reciprocating frame, which opens and closes the scalehopper valve. The scale-hopper valve, which, as shown, consists of two shutters 119, has a lever-and-link connection with rod 120, which is connected by arm 121 with a projection from the cross-head 102 of the reciprocating frame. The mechanism for rocking said shaft 110 will now be described. A torsion-spring 121 tends to rock the shaft in a direction to pull down the piston-valve 118, and thereby apply the air-pressure to the piston 101 and drive the reciprocating frame in a direction to close the scale-hopper valve. This tendency, however, is resisted by the engagement of a stop-lever 122, fixed to the rocker-shaft,with the head of the pivoted vertical tripping lever 123, whose lower end strikes against the end of the short arm of the horizontal lever 124. When the scalebeam 125 tips under the weight of a load on the scale 143, the hook on the under side of the scale-beam engages the long arm of the lever 124 and tips it up, thus dipping the rear short arm and releasing the lower end of vertical lever 123, so that the rocker-shaft is allowed to turn under pressure of spring 121. The stop-lever 122 rides down along the side of the curved head of lever 123, turning lever 123 slightly on its pivot and throwing forward the lower end of said lever 123, so that it stands above the reduced rear portion of lever 124.

The mechanism for rocking the shaft 110 in a direction to lift the piston-valve 118 and reverse the application of pressure so that the reciprocating frame moves rearwardly to open the scale-hopper valve is actuated by the moving carrier-ring, and is thus described. A cam-lever 126 is pivoted at 133 to the fixed ring 127 and is so located that when the movable ring 3 rotates a projection from the ring 3 will ride over the cam-lever and cause it to turn down on its pivot. The carrier-fingers 4 may serve to do this. The movable end of said cam-lever is connected by a link 128 with the lever 129, which is fast to clutch-disk 130 on rocker-shaft 110. Said disk 130 forms the driving member of a clutch and engages with disk 131, which is slidable on said rockershaft, but rotates only with the shaft. A spring 132, which must be more powerful than spring 121, tends to lift the cam-lever 126 and hold it in contact with the projecting finger 4, and when the clutch-disks are in engagementwith each other it turns the rockershaft 110 in a direction to lift the piston-valve 118. A yoke-lever 134, fulcrumed to fixed ring 127, is connected with the sliding disk 131 and also with the lower end of vertical lever 135, which extends upward into the path of the reciprocating frame. A spring (not shown) normally holds lever 135 in a position to hold the two disks 130 and 131 in engagement with each other. Then the carrier-ring 3 revolves, the finger 4 rides over the cam-lever 126 and first depresses it, then allows it to rise by degrees, and when it rides 0d the end of the cam-lever the spring 132 will throw the cam-lever up its full limit. This turns the disk 130, and thereby turns the disk 131 and the rocker-shaft 110 and lifts the piston-valve 118 and causes the reciproeating frame to move rearward and open the scale-valve. When the rocker-shaft has partially turned under the influence of spring 132, the pin 136 rides up along the head of lever 123 on the opposite side from stop-lever 122 and turns lever 123 far enough to disengage it from the upper side of lever 124. The forward end of lever 124 will then drop and raise the rear end high enough to prevent lever 123 from again moving forward under the action of lever 122 farther than to engage the rear end of lever 124 until said lever 124 is tipped by the scale-beam 125 under a load. \Vhen the reciprocating frame moves rearward, it engages upright lever 135 and turns it far enough to disengage the clutch- disks 130 and 131 from each other, thus releasing the rocker-shaft from torsion of the spring 132 and allowing it to respond to the spring 121. The stop-lever122, which engages lever 123, prevents the rocker-shaft from turning far enough to shift the valve 118 until the lever 123 is disengaged from the end of lever 124 by the tipping of the scale-beam. When the scale-beam is tipped by a load, the lever 123 will be disengaged from the end of lever 124, and the lever 123 being free to turn the torsion of spring 121 will turn rocker-shaft 110 and cause piston-valve 118 to move down and admit pressure to close the scale-hopper valve.

The mechanism for pressing the goods into the packages is shown in connection with the first hopper. The object is to provide mechanism to press down the goods as fast as they are fed into the package. In the machine shown in the drawings the feeding in the first hopper is by means of a worm 10, which extends down through the nozzle 11 of the hopper. This nozzle should be substantially the shape of the carton or package and small enough to enable the nozzle to go inside of the package. Mounted on the worm-shaft 34 are the stirrers 152. The empty package is placed in a holder 12, which is secured to a plate 13, mounted on the upper ends of the vertical slide-rods, 14, which pass through holes in the table 15 and also through holes in the guide-block 16, secured to the frame 17 of the machine. A pulley-cord 18, secured at one end 19 to the frame of the machine, passes down around a pulley 20, attached to a treadle 67, thence up through a clamp 22, which connects the two rods 14 and clamps the cord, thence up over pulley 23, and carries at its end a weight 24. The weight 24 tends to hold the slide-rods 14 in their elevated position, the adjustment being such that when in the elevated position the empty package standing in the holder 12 will be raised high enough for the lower end of the nozzle 11 to eXtendin to the bottom of the package. As the Wormfeed 10 revolves and feeds goods into the package there will be a constant pressure of the end of the worm on the goods, tending to crowd them down. The pressure will be sufficient to overcome the weight 24 and will push down the package as fast as filled, thereby of course pushing down the holder and the slide-rods l4 and treadle 67 until the feed stops. The further downward movement will be made by the operator pressing down the treadle until the plate 13, which connects the upper ends of the slide-rods, is brought down to the table 15. The top of the plate 13 when .in its lowermost position should be on a level with the track 5, so that the package may be easily moved onto the track when the carrier moves to transfer the package to the scale. In order to permit ready insertion of a package into the holder from the front instead of from above, the sides are secured to the front wall 61, but not fixed to the rear wall nor to the base. The front wall 61 is hinged at the bottom, so that it may be pulled over on its hinge and bring the side walls down also. There are side latches 62, which engage with catches 79 to connect the side and rear walls together. One of the side walls 63 is also preferably hinged to the front wall, so as to swing laterally. This is to prevent the side wall from binding on the package when the front of the holder is being opened.

The mechanism for starting the worm-feed will now be described.

Pivoted to a bracket 25 on the under side of the bed of the machine is a lever 26, whose rear arm is connected with the lower end of a rod 27, the upper end of rod 27 being connected with one arm of a crank-1e ver 28. The other arm of crank-lever 28 is connected with a clutch 29 on shaft 30 and moves the clutch into and out of engagement with pulley 31. The shaft 30 is connected by bevel-gears 32 33 with the worm-shaft 34. A spring 66 on rod 27 gives elasticity to the clutch connection. The forward arm of lever 26 extends forward past one of the vertical slide-rods 14 and is adapted to be engaged and lifted by a projection 35 on the side of the rod 14 when the slide-rods rise. Pivoted to the frame in front of the forward end of lever 26 is a hooklever or dog 36, having a torsion-spring 37, which tends to turn the dog on its pivot, the tail of the dog pressing against the lug 39 on rod 14 when the front end of lever 26 is down, and as soon as the front arm of lever 26 is lifted far enough for its end to clear the hook of dog 36 dog 36 will be turned so as to bring the hook 38 to the under side of lever 26 and hold lever 26 up. The lifting of the forward end of lever 26 pulls down rod 27 and throws the clutch 29 into engagement with pulley 31, so as to start the worm-feed as soon as the carton has been raised to the nozzle.

The mechanism for stopping the worm-feed is as follows: Secured to the rod 14 is a lug 39, which when the rods 14 descend will engage a tail 40 on the dog 36 and trip the hook 38 away from the lever 26, allowing the front arm of lever 26 to drop, as it will do, from gravity, the forward arm being heavier than the rear arm, its descent being also aided by a spring 66. The dropping of the forward end of lever 26 lifts its rear end and disengages clutch 29, thereby stopping the feed. The adjustment of the trip is such that it will occur when the package has received the approximate quantity of goods intended to be fed into it from the first hopper.

It is important that the carrier-ring shall not start until the preliminary feed and the scale or drip feed are both shutoff, and mechanism is provided by which this is accomplished, as follows: The clutch 41, as already described, is held out of engagement by a stop-lever 80 while the feed is open, and the ring cannot revolve until said stop is tripped by the forward movement of pin 7, said pin being normally held back, as shown in Fig. 9, by spring 8. On the side of one of the side rods of reciprocating frame 6 is a projection 42, which when the reciprocating frame is in its forward or scale-valve-closing position, is nearly in engagement with an arm 43, which is fixed to the pin 7. Arocker-shaft 44, supported in bearings 45, has attached to it a wedge-shaped arm or cam 46, which when the shaft 44 is turned from right over to left in Fig. 5 will enter between the arm 43 on pin 7 and the projection 42 on the sliding frame. If the sliding frame is in its foremost position, the cam-wedge will rub against the projection 42 and will cause shaft 44 to slide forward slightly and will push against arm 43 with sufiicient force to push pin 7 forward and turn the stop-lever 80, so that the clutch 41 will become engaged and allow shaft 9 to revolve, thereby moving the carrier-ring 3 through its arc of movement. The sliding frame 6 is for all practical purposes fixed for the time beingthat is, unyielding to the pressure of the wedge-arm 46-so that the full longitudinal movement occasioned by the wedge is imparted to the rocker-shaft 44 and sliding pin 7. If the rocker-shaft 44 be turned so as to bring the cam-wedge into its operative position before the sliding frame moves forward, then when the sliding frame 6 does move forward the rocker-shaft and wedge will be pushed forward slightly, enough so that the pin 7 will be given the necessary movement to release the stop-lever from the clutch.

The means of operating the rocker-shaft 44 is as follows: A crank-arm 54 is loosely journaled on shaft 44 by a sleeve or hub 47, so that either the hub or the shaft may be turned without turning the other, except when they are bolted together, as hereinafter described. Pinned to the shaft 44 on each side of the hub 47 are collars 48 49. In the inside of the wall of collar 49 there is an endwise slot 50. (See Figs. 8 and 10.) Hub 47 is also formed with an endwise slit 51 in the inside of its wall, within which is a slide-bolt 52. Behind the bolt 52 is a spring 53. When the hub 47 is turned on rocker-shaft 44 by crank-arm 54 and its connections far enough to bring the hub-slot 51 into alinement with the slot of the collar 49, said spring 53 will throw the end of the bolt into slot 50 and lock the hub 47 to the collar 49, so that as the collar 49 is fast to the shaft 44 the continued movement of crank-arm 54 will rock the shaft 44 and turn up the wedge 46, as above described. On said shaft 44 is a torsion-spring 58, which is also a thrust-spring. When the shaft 44 is turned in the manner just described the torsion-spring 58 will be wound more tightly. Secured to the bolt 52 is a stud 55, which projects outward through an elongated slot 56 in the side of the hub 47, said slot 56 opening into slot 51, in which the bolt lies. When the shaft 44 is moved forward by the engagement of cam-wedge 46 with the projection 42, said stud will engage with a stop 57, so that as the shaft moves lengthwise, carrying with it hub 47 and collars 48 and 49, the bolt 52 will be held still. On account of the onward movement of the hub 47 and collars 48 and 49 with the shaft while the bolt is engaged by the stop the bolt will be withdrawn from the slot 50 in collar 49 and be brought back entirely within slot 51 in the hub, or, more literally speaking, the collar and hub being carried on with the shaft 44, While the bolt is stationary, with its end abutting against the stop, the bolt is brought entirely within slot 51, with the same effect as if pushed back, thus compressing the spring 53 behind the bolt, and the hub will thus be unlocked from the collar. This leaves the shaft free to turn without turning the hub. Torsion-spring 58, which has just been wound up by the turning of the shaft, will thereupon turn the shaft 44 in the reverse direction and turn wedge-arm 46 down out of engagement with arm 43 on the sliding pin and arm 42 on the sliding frame. When thus disengaged, the spring 58 will contract and pull the shaft 44 back again in a longitudinal direction. This will of course carry back the hub 47 on account of its being held between the collars 48 49; but the slots 50 and 51 being outof alinement with each other the bolt 52 will be held back in the hub-slot 51, with its spring 53 under compression, ready to throw the bolt as soon as the two slots are again brought into alinement with each other. Pivoted to the crank-arm 54 is a rod 60, which extends along the under side of the table 15, above which is the plate 13, on which rests the carton holder 12, the rod extending through a guide-hole in the frame beneath the table and projecting out somewhat beyond the front. Secured to the front of the holder is a handle 64, which not only serves as a handle to open and close the hinged door, but it serves as an actuator to start the carrier-ring if the scale-valve is closed. When the front door 61 is turned down, the handle 64 strikes the end of rod 60, as shown in dotted lines in Figs. 3 and 6, and pushes rod 60 backward, thereby pushing back the lower end of crank 54 and turning shaft 44 as soon as the crank has turned far enough for the bolt 52 to be thrown into the slot in collar 49, as already described. After the carrier-ring has moved through its arc of motion and has stopped a fresh carton will be placed in the holder and the front closed again. As soon as the handle 64 is withdrawn from pressure on rod 60 the spring 65 will bring rod 60 forward again, drawing with it the lower end of crank 54. The rear wall 68 of the holder does not drop when the carrier moves. It therefore cannot be made short enough to permit the carrier-fingers 4 to ride over the top of it; but in order to properly support and retain in form packages which are higher than the wall 68 it is necessary that there should be an additional rear support. Means for doing this are shown in the drawings and are described as follows: Secured to the bracket 69 are guide-rods 70, to which is journaled a plate 71 by means of the rings 72, so that the plate may slide up and down on rod 70. Secured to the upper part of the side walls 63 are hooks 73, which when the holder is carried up by the rods 14 will engage with the under side of the rings 72 and carry up the plate 71, as shown in Fig. 3, raising it sufficiently to form a rear supportfor the upper part of the package. When the rods 14 and the holder and package descend, the plate 71 will also slide down again. When in its lowermost position, the plate 71 is too high to be engaged by the carrier-fingers.

The cycle of operations will now be described, the scale-valve being closed, the

worm-feed clutch disengaged, the elevator in its lowermost position, the treadle being held down by the foot of the operator or blocked or held in any other way. The carrier-ring cannot now move, because the wedge-arm 46 is not in position to press the sliding pin 7. The scale-valve remains closed, because the movement of thecarrier-ring is required to open it. The worm-feed cannot start until the elevatoris raised by the weight 24 after the treadle is freed. When the operator is ready to start the machine, he by hand turns down the front 61 of the package-holder, as shown in Fig. 3. The handle 64 will engage with the end of rod 60 and through its connections will turn rocker-shaft 44, so that wedge-arm 46 will be turned up between the end of bar 42 and arm 43, thereby moving the sliding pin 7, and start the carrier-ring 3 in the manner already described. The carrier-ring will move far enough to advance all the packages one stage. removed from the scale, the partially-filled package will be removed from the holder and carried along the track toward the scale a distance equal to the arc of movement of the ring, as already described, and the partiallyfilled package next behind the package which was removed from the scale will be carried to the scale. The scale-valve will be opened by the carrier at the end of its movement, as already described, by the turning of rockershaft 110 to actuate the piston-valve 118 and apply the air-pressure to move the reciprocating frame rearwardly. The worm-feed cannot start until the operator releases his foot from the treadle. When the carrier-ring stops, a package is placed in the holder, and the front 61 is turned up by hand and latched. The spring 65 throws rod 60 forward again, turning rocker-shaft 44 in a direction to turn the wedge-arm 46 out of its engagement with pin 7, so that when the reciprocating frame again moves forward it will not start the carrier-ring until the operator is ready. When the package is in position in the holder and the door 61 closed, the operator will relax his foot-pressure on the treadle and allow the weight 24 to descend and lift the packageholder in the manner previously described. As the slide-rods 14, attached to the holder, move upward the lug 35 on one of the rods 14 will raise the forward end of lever 26 and throw the clutch 29 into engagement with pulley 31 to start the worm-feed. The rising of the holder carries the package up, so that the nozzle 11 will be inside of the package. The hook 38 engages the lever 26 in the manner previously described and holds it until the worm-feed has depressed the package and elevator a certain distance, when the hook 38 will be disengaged from the lever 76 and allow the forward end to drop and raise the rear end and disengage the clutch, thereby stopping the worm-feed. The scale -valve will be closed by the tipping of the scale, as described, independently of the stopping of The filled package will be ICC the worm-feed; but the carrier-ring will not move until the operator again pulls down the handle 64. He will then depress the treadle to bring the package-holder down to a level with the track, and if he desires to continue the operation he will turn down the front 61 and proceed as before. Thus the beginning of each cycle of movement is at the will of the operator.

It is obvious that instead of the weight and treadle there may be readilysubstituted other forms of mechanism under control of the operator for starting the elevator at the beginning of each cycle.

8. In a packaging-machine, a holder for retaining a package while material is being compressed in the package, mechanism for compressing the material into the package while it is in the holder, means for releasing said holder from said package, and mechanism actuated by the releasing of said holder to remove said package, substantially as described.

9. In a packaging-machine, a holder for retaining a package while material in the package is being compressed, means for compressing material into said package, a packagecarrier, mechanism for actuating said carrier, mechanism connecting said holder with said actuating mechanism whereby said carrier cannot move until said holder is out of the path of movement of said carrier, substantially as described.

10. In a packagingmachine, a packagecarrier, mechanism which actuatos the carrier, a stop adapted to limit the movement of said carrier to a prearranged cycle of actuation,mechanism controlling said stop,a holder for holding packages while being supplied with material, mechanism for releasing the packages from said holder, and mechanism connecting said holder with said stop-controlling mechanism whereby said packagecarrier can move only when said holder is in a released position, substantially as described.

11. In a packagingmachine, a package- 'carrier, a package-holder having upright walls to retain the package in position while being filled, a hinged drop-front, and mechanism actuated by the dropping of the front to start the carrier substantially as described.

12. In a weighing and packaging machine, a scale, two feed mechanisms one of which supplies to each package a part of the required load and the second of which supplies it with the balance of the required weight, mechanism for carrying the package from the place where it receives the first instalment to the scale where it receives the balance of the load, mechanism which opens and closes the scale-feed, mechanism which actuates the carrier, mechanism which stops the carrieractuating mechanism at the end of each cycle of movement, a holder for the package at the first feed, a hinged front to the holder to release the package after it has received its preliminary load and to admit a new package, and mechanism which releases the stop from the carrier-actuating mechanism, said releasing mechanism being actuated by the combined action of the scale-feed-closing mechanism,and mechanism actuated by opening of the package-holder at the first feed,substantially as described.

13. In a weighing and packaging machine, a scale, two feed mechanisms of which one supplies to each package a part of the required load and the other supplies it with the balance of the required weight, mechanism which carries the packages from the first place of feed to the second, mechanism actuated by the tipping of the scale to close the scale-feed, mechanism for starting the carrier which is actuated by the combined action of the closing of the scale-feed and of other mechanism actuated at will by the operator, both mechanisms being essential to the operation, substantially as described.
