' TOBACCO-PACKING IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 565,349, dated August 4, 1896.

Application led October 4, 1895.

To all whom t may concern:

Be it known that I, CORNELIUS WATSON GUERRANT, a citizen of the United States, and a resident of Danville, Pittsylvania county, Virginia, have invented certain Improvements in Tobacco-Packin g Machinesof which the following is a specification.

The object of my invenion is to construct a bag-iilling machine which will be entirely automatic in its action save as regards the application of the empty bags to the fillingmolds and the removal of the filled bags from the machine. This obj ect I attain in the following manner, reference being had to the accompanying drawings, in which- Figure 1 is a side view of the machine. Fig. 2 is a vertical section of the same. Fig. 3 is an end view. Fig. 4 is a sectional plan View on the line 4 4, Fig. 2; and Fig.'5 is a sectional plan view on the line 5 5, Fig. 1.

The xed frame 1 of the machine has bearings in its lower portion for the driving-shaft 2 and the cam-shaft 3, a spur-pinion 4 on the driving-shaft meshing with the spur-wheel 5 on the cam-shaft, so as to drive the latter at a rate of speed considerably less than the shaft 2 and with correspondingly-increased power. The shaft 2 has at one end a pulley 6 for receiving a driving-belt, this pulley being loose on the shaft but capable of being clutched thereto by any ordinary form of laterally-mow able clutch, such, for instance, as is represented at 7.

On the shaft 3 is a cam 8 and two arms 9 and 10. The cam 8 acts upon 'an arm 11, pivoted at one end to one of the cross-bars of the fixed frame and bearing at its free end against a stud or pin 12 on a sliding rod 13, which is connected to a cross-head 14, from which extend upwardly, through suitable guide-openings in the cross-bars of the fixed frame, a pair of rods 15, the latter being connected at their upper ends to a cross-head 16, which carries a plunger-rod 17, the latter having, at its lower end, any suitable form of plunger for compressing the material in the bag t0 be filled.

The plunger-frame is elevated by the action of a weight 18, which is suspended upon a cord or wire 19, passing over guide-pulleys 2O at the top of the machine, the Weight being guided upon rods 21 and being hollow,

so that when at the limit of its descent it can slip over a box or plug 22, to which. it iits snugly, so as to form a dash-pot and check the further ascent of the plunger-frame.

Buffer-springs 23 are interposed between the upper cross-head of the plunger-frame and the top cross-bar of the fixed frame, as shown in Fig. 3.

Suitably mounted so as to be free to be rotated in bearings in a table or bed 24, but vertically conned to said table or bed, is a hollow vertical standard 25, which has at its upper end a disk 26, upon which are mounted a series of filling-mold carriers 27, guided vertically upon rods 28, which extend upwardly from the disk and are held in position laterally by means of vertical guide-rods 29, so that they are capable of vertical movement, but cannot swing or be removed from their proper radial position on the disk 26. Each of the carriers has projecting arms 30, notched for the reception of pins at the upper end of a metal tube 31, which constitutes a filling-mold, and which is held in position on the carrier by means of spring-retainers 32, the tube serving as a support for the bag 33,

'which is to be lled.

Intermittent movements of partial rotation are imparted to the disk 2G by the action of a pin on a crank-arm 10, said pin acting upon one arm of a lever 34, which is hung to the lower end of a bell-crank lever 35, pivoted to a suitable bearing on the fixed frame and connected at its upper end to a spring-pawl 36, which is adapted to engage with pins 37 on a disk 38, secured to that portion of the shaft 25 which projects below the table 24, there being in the present instance four of these pins, so that on each vibration of the lever 35 the shaft 25, its disk 26, and the parts carried thereby will be moved to the extent of a quarter-turn.

lThe fractional movement will of course depend upon the number of carriers mounted on the disk 2G, four carriers being shown in the present instance simply for the purpose of illustration.

Secured to the shaft 25, below the disk 38, is a notched disk 39, and with the notches of this disk is adapted to engage a lug 40 upon an arm 41, which, as shown in Fig. 4, is hung to a bracket on a fixed frame and is acted IOO upon by a spring 42, tending to maintain the lug 40 in engagement with a notch of the disk 39.

Forming part of the operative mechanism of the machine, however, is a vertically-sliding rod 43, upon which is a cam-lug 44, adapted to act upon a projection 45 on the arm 41, so that as said rod 43 descends the arm will be pushed outward against the action of the spring 42, so as to withdraw its lug from the notch of the disk 39 and thus permit the turning of the latter by the pawl 36, the ascent of the rod 43 permitting the arm 4l to resume its normal position, so as to again lock the disk 39.

The rod 43 is operated by the pin of the arm 9, said pin acting upon an arm 46, which is hung to the bracket on the xed frame and is connected by a suitable link to the rod 43.

The upper end of the rod 43 is adapted to act upon the lug 47, depending from each of the carriers 27, as the latter is brought into position over the upper end of the rod, so as to impart a vertical sliding movement to the carrier and to the filling-mold 31 hung thereto, and in order to prevent side contact of these lugs with the upper end of the rod 43 as the disk 26 is turned and the carriers swing around in position I provide the table or bed 24 with an elevated inclined rail 48, Fig. 1, over which the carrier rides as the disk is turned and by which said carrier is slightly elevated, so that when it finally leaves the high end of the rail it will drop into position with its lug 47 directly above the top of the lifting-rod 43.

A tension-spring 50 is interposed between the levers 34 and 35, and if there is any undue resistance to the rotation of the shaft 25 and disk 26 the lever 34 only will be moved by the pin of the crank-arm l0, the spring 50 yielding to permit such independent move-' ment. The spring, however, is so strong that in the ordinary operation of the machinethat is to say, when the rotation of the shaft 25 and disk 26 meets with only normal resistance, the levers 34 and 35 will act practically as one. A pin 51 on the lever 35 serves by contact with the lever 34 to limit the approach of said levers.

At one end of the shaft 2 is a cam 52, which acts upon the lower arm of a lever 53, hung to a suitable bearing on the fixed frame of the machine, the upper arm of said lever being acted upon by a spring 54, which tends to keep its lower arm always in engagement with the cam. The upper end of the lever 53 is connected by a link 55 to an arm on an upright shaft 56, upon which are mounted two perforated segments 57 and 58, which play in slots in a feed-tube 59, suitably mounted upon an upright rod GO.

The segments 57 and 58 are separated vertically from each other to such an extent that the capacity of that portion of the feed-tube between the two segments will equal the desired charge for the bag, and the openings in the two segments are oset in respect to each other, as represented in Fig. 5, so that when the opening of the upper segment is in line with the feed-tube the opening of the lower segment will be out of register therewith and vice versa. /Vhen the segments are at one limit of their movement, the opening in the upper segment is in line with the feedtube and the material can pass down -tlirou gli the same onto the lower segment and can iill that portion of the feed-tube between the two segments. When the segments are moved, the first effect of the movement is to carry the opening of the upper segment out of register with the feed-tube and thus cut oif any further supply of material, the opening of the lower segment being finally brought into register with the feed-tube, so as to permit the charge previously deposited between the two segments to flow down through the feedtube, through the bag-filling mold, and into the bag, which has been previously adjusted upon the lling-mold and carried beneath the feed-tube in order to receive the charge.

The operation of the machine is as follows:

`A bag being applied to one of the fillingmolds 31, the latter is first brought under the feed-tube 59 and the bag receives its charge.

Q The next movement of the disk 26 brings the tube and its bag directly under the elevated plunger, a second bag being brought under the feed-tube.

As soon as the parts are properly moved into position the plunger def scends, so as to force the charge tightly into the bag, and owing to the character of the cam 5 8 the plunger remains in the depressed position for some time, so as to permit of the elevation of the filling-mold 31 under the action of the lifting-rod 43 to such an extent as to withdraw it from the bag, the plunger being then elevated, so as to permit of the removal of the bag, and the tube 3l being lowered prior to a further movement of the disk 26, so as to bring the newly-filled bag under the plunger and afresh bag under the filling-tube. These operations are repeated indefinitely, so that the machine is practically automatic in its action, save as regards the necessity of applying the empty bags and removing the filled ones.

Extending up through the table or bed 24, directly below the filling-tube 59, is a spout 61, which receives the charge of material from the filling-tube in the event of there being no bag in position to receive it.

Having thus described my invention, l claim and desire to secure by Letters Patent l. A bag-filling machine in which are combined a disk provided with means forimpart- `ing to it intermittent movements of partial rotation, a series of mold-carriers, one for each mold, said carriers rotating with said disk but `mounted so as to be capable of sliding vertically, bag-filling molds detachably hung to said sliding carriers, an intermittently-actul ated reciprocating packing-plunger, a feeding device, and means for vertically reciprocat- IOC IIO

ing the mold-carriers in succession as the bags are lled, substantially as specified.

2. A bag-lilling machine in which are combined a disk provided With means for imparting to it intermittent movements of partial rotation, carriers on said disk, bag-filling molds hung thereon, a reciprocated packingplunger, the feed pipe having segmental valves located one above the other and having openings therein, the opening of one valve being out of line With that of the other, a rockshaft carrying said segmental valves, and means for rocking said shaft at intervals, substantially as specified.

3. A bag-filling machine in which are combinedra disk provided With means for imparting to it intermittent movements of partial rotation, bag-filling molds mounted so as to slide vertically on said disk, a lifting-rod for raising said bag-filling molds and an inclined rail for partially lifting the bag-filling molds before they reach a position to be acted upon by the lifting-rod, substantially as specified.

4. A bag-filling machine in Which are combined a disk, a series of bag-filling molds carried by said disk, a packing-plunger, and means for imparting intermittent movements of partial rotation to the disk, said means comprising a paWl-carrying lever, a supplementary lever mounted on said paWl-carry- 3o ing lever, a spring whereby it is held normally in proper relation thereto, and an operatingis operated by said reciprocating rod, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
