MECHANISM FOR FILLING AND SETTLING GOODS IN PACKAGES.

SPECIFICATION forming part of Letters Patent No. 767,893, dated August 16, 1904.

Application filed March 8, 1902.

To all, whom it may concern.-

Be it known that I, 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 Mechanisms for Filling and Settling Goods in Packages,of which the following is a specification.

The main object of this invention is to provide mechanism for packaging and settling goods in cans, packages, or other receptacles and also for securing complete discharge into the can or other receptacle of the intended quantity whenthe goods have first been weighed or measured out into a preliminary holder and are afterward emptied into the can or other receptacle.

It also has for its object other features, which will be set forth hereinafter.

The invention will now be fully described, and the novel features thereof will be particularly pointed out in the claims at the close of the specification.

In the best form of machine embodying the invention now known to me there are two rotary carriers mounted on the same vertical shaft and moving in unison, the lower carrier carrying the receptacles to be filled and the upper carrier carrying a series of funnels which are in alinement with the receptacles beneath. These funnels and receptacles are successively brought around into position to receive the load which is delivered to the receptacles through the funnels. The carriers move intermittently in unison with the carrier for the package-filling mechanism. Tapping mechanism is provided by which each package is tapped at periods of rest between the movements of the carrier. New recep- 4 tacles are supplied to the carrier at the entrance as rapidly as the filled ones are removed at the place of exit. The funnels, however, continue the round of operations again.

In the drawings, Figure 1 is a plan, sectioned on line 1 1 of Fig. 2, of a machine embodying the invention in combination with a portion of a weighing or packaging machine in Serial No. 97,289. (No model.)

which the required weight or quantity of goods is first delivered into receptacles which 5 are afterward emptied into the cans or packages. Fig. 2 is an elevation viewed from the left of Fig. 1. Fig. 3 is a detail plan of the train of gears which connect the shaft of the settling mechanism with the gear-ring of the 5 5 weighing or packaging machine. Fig. 1 is a sectional detail on line 5 5 of Fig. 1. Fig. 5

is a sectional detail showing one of the tappers and the ratchet which operates the tapper. Fig. 6 is a plan of the mechanism for feeding the material into and weighing it in the temporary receptacles and for discharging into the permanent receptacles. Fig. 7 is a detail view of one of the temporary receptacles.

Referring now to the drawings, 1 is a hopper, suitably supportech'into which the goods are emptied for delivery to the receptacles.

On the rotary shaft 2 is mounted a spider 3 in form of a spoke-wheel carrying a series 7 of funnels 4, attached to arms 5, which project from the periphery of the spider. Inthe operation of the machine these funnels are successively brought beneath the hopper 1. Below the funnels 4 is a circular track 6, which extends around beneath the funnels and the hopper 1. Connected with the track is a table 7, onto which the receptacles 3a are fed by a carrier-belt 8, driven by a pulley 9.

Mounted on the shaft 2 is a spider 10 below spider 3 and of similar form to spider 3. Projecting from the periphery of spider 10 are arms 11, carrying finger-blocks 12, provided with fingers 13, which engage the receptacles and push them around on the track 6. The 5 finger-blocks 12 are equal in number to the funnels at and are so located that the receptacles when engaged by the fingers 13 will be directly beneath the funnels and will be kept in the same relative position while the recep- 9 tacles are carried around the tracks. Mechanism is provided, as hereinafter explained, by which the shaft 2, and consequently the spiders 3 and 10-, are given an intermittent rotary movement,each movement being through an are equal to the distance between two funformed by the block and the fingers ready to be carried along on the track at the next movement of the shaft 2 and the spiders.

The funnels 4: are preferably formed with a flange-base 14, having a turned-down flange or lip 15 around the periphery. The under side of the base is preferably provided with a pad, of felt or other suitable material, surrounding the outlet, so that when the upper end of the receptacle is brought up against the base of the funnel the fine particles of the goods cannot escape during the discharge from the hopper. In order to permit bringing of the receptacle up close against the bottom of the funnel, the table is somewhat lower than the main part of the track, and the portion of the track which leads from the table is on an incline for a short distance, so that when the receptacle is delivered onto the table therewill be a space between the top of the receptacle and the bottom of the funnel above it, as shown in Fig. 1. When the spider revolves, the receptacle will be carried up the incline of the track, and when the level track is reached the top of the receptacle is brought up against the bottom of the funnel.

There are preferably guide-rails 16 at the sides of the carrier-belt 8. In order to guide the receptacles during the passage from the table and up the incline, guides 17 are provided. The track descends again where it approaches the table at the end of the circuit to allow the receptacle to be brought away from the funnel, and the receptacle passes between guides 18, which conduct it to the belt 19,

which travels in the reverse direction to the belt 8 and is driven by pulley 20.

One form of mechanism for delivering the material into temporary receptacles and weighing it and discharging it into the permanent receptacles and giving intermittent movement to the shaft 2 and its actuated connections and which is the preferred means is as follows: A gear-ring 21 is made to revolve intermittently through a uniform distance at each period of movement. This can be done in well-known ways-such, for instance, as shown in Patent No. 633,675 to G. W. Watson, dated September 26, 1899, or Patent No. 556,231 to G. W. Watson, dated March 10, 1896, or in my application for United States Patent, filed February 13, 1902, Serial No. 93,886, in which the gear-ring is at rest while a package is being filled with a predetermined quantity of goods and which is moved after thescale tips. Engaging with gear 21 is a pinion 22, which is mounted on 27 28 29 and pinion 30 with a gear31 on the shaft 2. The gears are so adjusted that at each period of movement of the gear 21 the shaft 2 will be revolved through the arc necessary to give the required movement to the spiders 3 and 10, as already explained.

Connected with the Weighing or preliminary measuring-machine is a track 32, around which are carried receptacles 33, into which are successively delivered a predetermined weight or quantity of goods and which are moved intermittently by the action of the gear-ring 21, so as to bring a loaded receptacle 33 above the hopper 1 at the end of each period of movement of the gear-ring, which also brings one of the funnelset and one of the receptacles 34 beneath the hopper. Mechanism is provided by which the receptacles 33 are caused to discharge their contents into the hopper 1 and are then carried around to be refilled. This may be accomplished by forming the receptacles 33 with a valve 35 in the bottom hinged at 61, held by a catch 62, which is tripped when the receptacle reaches the proper position above the hopper and which is closed before the receptacle is again to be filled. In Fig. 7 the valve 35 is shown closed. In Figs. 1 and 6 the valve 35 is shown open, the receptacle 33 being then in a discharging position. The catch 61 may be tripped by engagement with a projection (not shown) between the rails of the track and reengaged when the receptacle moves away from the place of discharge by engagement of the valve with the rails of the track. As shown in Figs. 1 and 6, the rails have an open place at the discharge-station to permit downward opening of the valve. The feature of continuously filled and discharged receptacles forms the subject of another application for Letters Patent.

The mechanism for delivering the material into temporary receptacles and weighing it and then transferring the temporary receptacles and discharging them into the permanent receptacles'is shown in Figs. 6 and 7, although some of the details are omitted, as

they will be understood by reference to other patents above mentioned. The temporary receptacles 33 are moved around on the track 32 by fingers 51, which are attached to arms 52, projecting from a flange on the intermittently-movable gear-ring 21. The machine remainder of its required weight. In the machine shown in Fig. 6 53 represents the preliminary sup1i lyhopper and 54 the scale feedhopper.

Gear-ring 21 is driven by driving-shaft 55 through suitable connecting mechanism, in-

cluding mechanism, such as a clutch, (not shown,) by which the ring 21 may be thrown into and out of connection with the drivingshaft. A reciprocable member 56 opens and closes a valve to the scale-hopper 54. Vhen the scale tips under the weight of the load in the receptacle, mechanism is actuated thereby, which causes the reciprocable member 56 to move forward and close the scale-hopper valve. When the frame 56 thus moves forward, a projection 57 on the reciprocable member 56 engages an arm 58, carried by a slide-rod 59,

and causes said slide-rod to render operative the clutch which connects driving-shaft 55 with the shaft of a pinion which meshes with gear-ring 21. Said clutch and pinion and pinion-shaft are fully shown and described in Patent No. 633,253 to Watson, dated September19, 1899. hen the clutch connection is made, the gear-ring2l is moved by said pinion until the clutch is disengaged. Slide-rod 59 is turned to bring arm 58 out of engagement with the reciprocable member 56, so that spring 60 will throw slide-rod 59 back before the said pinion has completed its revolution, and thereby actuate mechanism to stop the pinion at the end of one revolution. The size of the pinion determines the are through which the gear-ring 21 moves at each cycle of operations. The receptacle-mow ing finger-arms 52 should be spaced so that at each period of movement a receptacle will be deposited on the scale.

Mechanism is provided which is actuated by the tipping of the scale to move the reciprocable member 56 forward to close the scalehopper valve and which is actuated to move said member 56 rearwardly to open the 11013 plication Serial No. 93,886 the reciprocable member is actuated by fluid-pressure. The machine shown in Fig. 6 of the accompanying drawings is especially designed to be operatedby fluid-pressure; but any of the mechanisms shown in the patents above mentioned may be applied to it.

The two side bars 56 of the reciprocable frame are slidably mounted in bearings 63 and are connected with each other at the ends by cross-heads 64 65. Connected with the rear cross-head 64 is a piston-rod 66, which connects with a piston (not shown) in cylin- 65 is a piston-rod which connects with a piston in the forward part of said cylinder 67.

A vertically-movable piston 68 is operated by fluid-pressure admitted to the chamber of piston 68 through pipe 69, said piston 68 be ing operated by mechanism (not shown) which is actuated by the tipping of the scale to admit pressure to move the reciprocable member forward and actuated by mechanism after a receptacle reaches the scale to admit pressure to move the reciprocable member rearward.-

The spiders 3 and 10 are preferably adjustably clamped to the shaft 2, so that they may be set according to the capacity of the receptacles to be filled.

As there will sometimes be a slight variation in the weight of receptacles which are intended to be of the same size and as it is desirable to have the receptacle it close up to the padded bottom of the funnel in order to provide for such slight variation and still retain the close joint, the track 6 is preferably made somewhat yielding, as by having the track supported on springs 36.

The mechanism for tapping the receptacles to settle the goods will now be described.

Loosely mounted on shaft 2 is a wheel 37, having crown ratchet teeth or cams 38. On the hub 39 of this wheel is a pulley 40, by which the wheel 37 is continuously revolved. Mounted on pivots 41 in brackets fixed to the standard 43 are a series of levers 44, the inner ends of which extend inward, so that their under sides are engaged by the ratchet-teeth 38 and caused to continuously vibrate up and down. The outer arm of the lever is bent upward, so that its end will form a tapper, which as it vibrates will move up and down between the rails of the track 6. Tension is given to the levers by means of springs 47, thereby causing quick action and sharp blows by the tappers. The levers are so disposed that the vibration will cause the tappers to strike the bottoms of the receptacles 34 when the spider which moves the receptacles is at rest. The number and arrangement of the tappers should be such that the receptacle will be engaged by the first tapper when the receptacle is under the hopper and will be engaged by additional tappers at each time of rest until it comes around near to the table where it is transferred to the removable belt, the series of tappers being arranged in a circle concentric with the path of movement of the receptacles. Thus the receptacle is subjected to a much more thorough settling process than if it is tapped merely while being filled. In the device shown in the drawings there are twelve arms to each spider, showing that there will be twelve periods of movement, nine of which are between the hopper and the place of deder 67. Connected with forward cross-head I posit again on the table, and there are eight action one, two, three, or four tappers.

course the form and size or the rest may be.

tappers. Not only will the receptacles be shaken, but the vibration will be communicated to the tunnels resting on the tops of the receptacles, and thereby shake down any material which otherwise clings to the sides of the funnel.

It is obvious that the apparatus may be connected with a machine in which goods are first measured out into preliminary receptacles as well as when weighed.

The teeth 38 instead of being of ratchet form may be corrugations or other form of projections from the crown of the wheel.

With some classes of goods it may not be necessary or desirable that the receptacle should be subjected to tapping by the whole series of tappers. Mechanism is therefore provided by which a portion of the tappers can be thrown out of operative action. A segmental rest 49 is mounted on a sleeve outside of shaft 2 and is capable of being turned around on its center and by means of a set-screw or other suitable clampingmechanism held in its ad j usted position. It extends up above the ratchetteeth 38 enough so that wherever the rest a9 is placed the tappers will rest on it and it will prevent the teeth 38 from engaging and actuating the tappers. If it is desired to put into operation all of the eight tappers shown in the drawings, the segment 49 is turned around, so that it will be on that side next to the entrance and exit where there are no tappers. It can be moved so as throw out of varied, so as to be capable of throwing out of action more or less of the tappers.

The temporary receptacles may be of any suitable form or material, and for the sake of brevity they will in some of the claims be referred to as (:lummies, and for the same reason the worc can will be understood as representing anysort of receptacle to be filled which has been referred to in the specification as the permanent receptacle.
