SPECIFICATION forming part of Letters Patent No. 691 ,537, dated January 21, 1902.

Application filed July 25, 1901. Serial No. 69,635. (No modeLl To (all whom it may concern:

Be it known that 1, CHARLES OSCAR ERIC- son, of Helmetta, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Packing-Machines, of which the following is a full, clear, and exact description.

My invention relates to improvements in that class of machines which are used for packing loose material, such as snuff or tobacco, into bottles, boxes, or other packages; and the object of my invention is to produce a simple and efficient machine of this character which is adapted to pack char es of the material rapidly and snugly into the desired package; which is especially adapted for packing material which is more or less damp or sticky, as it has means for preventing the said material from sticking to the funnel through which it has to pass; which is adapted to pack the material without waste; which is very easily operated and kept in repair, and which in general affords means for packing such material cheaper and better than by the use of ordinary means.

To these ends my invention consists of a packing-machine the construction and arrangement of which will be herein described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar figures of reference refer to similar parts throughout the several views.

Figure 1 is afront elevation of myimproved machine. Fig. 2 is a broken side elevation thereof with parts in vertical section. Fig. 3 is an enlarged detail sectional View of the funnel and the plunger mechanism which reciprocates therethrough. Fig. 4 is a sectional plan of the hammer and scraper.

The packing mechanism is mounted and supported on a suitable frame 10, which may be of any approved construction, and it is my purpose to use the packing mechanism in connection with a hopper 11, containing a conveyer, which is driven by the gearing 12, the latter being driven from a driving-shaft 13, having tight and loose pulleys 14:, and the hopper 11 being arranged to discharge into a suitable weighing-scale 15.

The above mechanism as referred to in a general way forms the subject-matter of my funnel l6,into which the material to be packed is placed, and I have illustrated two such funnels and, in fact, duplicate packing mechanism throughout, as I find by using the packing devices in pairs much more rapid work can be performed, for in this way the packing is continuous and one device is stuffing the material into its package while a package is being removed and another substituted in the second packing device. I will therefore describe one packing device in detail. This funnel 1G is suitably supported and, as illustrated, is carried on a cross-piece 17, which can be angle-iron, and for convenience the funnel is arranged near a shelf 18, having a suitable back 19, so that the packages can be conveniently piled on the shelf while the machine is in operation.

The snout of the funnel 16 is held in a suitable collar 20, (see Fig. 3,) and the discharge of the funnel is into the bottle 21 or other package into which the snuff or other material is to be packed. The bottle or package 21 is adapted to rest on a little table 22, which is arranged beneath the funnel 16 and is carried on the top of a vertically-reciprocating support or rod 23, which slides through suitable guide-collars 24:, these being supported on the main frame by means of bracket-plates, as shown. Each rod 23 is pivoted to an arm 23, and this is provided with suitable weights 25 and 26, which are adjustable and which are adapted to hold the table 22 in a normally elevated position, or at least they will so hold it when the table is pushed up to the position shown at the right hand in Fig. 1. Each arm 23 connects by a pivotal link 27 with a hanger 28, which is suitably supported on frame 10. The lower end of the rod 23 extends into a cylinder 30 and is provided with apiston 29, to the end that the depression of rod 23 may be gradual as the package on the table 22 is filled and the table pushed downward. The cylinder 80 can be filled with glycerin or other similar liquid. On one side the upper and lower parts of the cylinder connect by a pipe 31, in which is a valve 32, which controls the flow of liquid, and a similar pipe 33 also connects the upper and lower parts of the cylinder, this being provided with a check 34. It will be seen that as the piston 29 goes down the liquid is forced up above the piston through the pipe 31 and that on the upstroke of the piston the liquid is forced to the lower part of the cylinder through the pipe 33. This arrangement of the cylinder with its liquid and the piston on the rod 23 is especially applicable where large packages are to be filled with snufi and where an even resistance must necessarily be imparted to the rod 23; but where small packages are used the cylinder and piston can be dispensed with and the rod permitted to slide freely.

The material to be packed is forced-downward through the funnel 16 by a hammer or plunger 35, which has a reduced shank 36 and a suitable head 37, adapted to pass closely through the snout of the funnel. The hammer or plunger is shown detachably connected to vertically-reciprocating rod 38; but ob viously the parts may be made integral, if desired. The rod 38 slidesthrough suitable guide- collars 39 and 40, (see Fig. 1,) the former being supported on the bracket-arms 41 and the latter on the machine-top.

In packing snuff or any other loose or sticky substance the tendency is for the material to stick against the wall of the funnel 16. To obviate this, I provide a scraper, (best shown in Figs. 3 and 4,) which is adapted to move downward close against the funnel-wall and scrape the material therefrom. As shown, the scraper comprisesja supporting-spider 42, which is secured to the hammer or plunger '35, the ring 43, carried by the spider, and the depending blades 44 and 45, which are of unequal length and which are hung pivotally on the ring 43. It will be seen that on the upstroke of the hammer or plunger the scraperblades hang loosely, but on the downstroke they fly outward against the wall of the funnel and as they move downward scrape off the material which would otherwise adhere. I find that by having the blades of unequal length the scraping effect isbetter and that a more even filling of material beneath the hammer results.

It is obvious that many well-known devices can be used for reciprocating the hammers or plungers 35; but means should be provided for regulating the stroke of the hammers, and they should be made to reciprocate alternately, so as to facilitate the shifting of the packages described belowthat is, so that one package can be removed when its hammer is up, while the hammer of the opposite package may, perhaps, be down. For this purpose I have shown each rod 38 pivoted to a lever 46, (see Fig. 2,) whichis centrally fulcrumed at 47 on a hanger 48 and which has several holes 49, in either of which the fulcrum-pin 47 may be placed so as to shift the stroke of the rod 38. The outer end of each lever 46 is pivoted to a connecting-rod 50,

whichis connected with an eccentric-strap 51, and this is carried on an ordinary eccentric 52 on the driving-shaft 13. This arrangement, it will be seen, makes a very convenient means for reciprocating the two hammers and for making their strokes alternate.

In operating the machine the package 21 to be filled is placed on one of the tables 22 and a charge poured into the funnel 16 above, after which the same operation is performed upon the second packing device, in each instance the table 22 being pushed up so as to bring the bottle or package 21 close to the funnel-snout, as in Fig. 3. In this connection it will be seen by referring to the said figure that a cushion 21 is provided, against which the mouth of the bottle may contact. It will be seen that the filling of two bottles can go on at the same time, and the attendant merely removes the filled bottle and substitutes another, while at the same time the charges for the funnel are of course supplied as fast as is necessary.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a machine of the kind described, the combination with the funnel and the reciprocating hammer which moves through the funnel, of a scraper carried by the hammer, said scraper comprisinga series of freely-swinging blades adapted to contact at their free ends with the side wall of the funnel.

2. In a packing-machine, the combination with the funnel and the hammer reciprocating through the funnel, of the scraper comprising a ring attached to the hammer, and a series of freely-swinging blades hanging from the ring so that their free ends may engage the funnel-wall. V

3. In a machine of the kind described, the

combination with the funnel and the hammer which reciprocates through it, of the scraper carried by the hammer, said scraper comprising a series of freely-swinging blades of different lengths, the ends of the blades being adapted to engage the funnel-wall.

In testimony whereof I have signed my name to this specification in the presencejot two subscribing witnesses.

CHARLES OSCAR ERIGSON.
