PACKER. FOR STOCK FEED.

; Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed April 19, 1918. Serial No. 229,585.

for Stock Feed; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improve ments in packers,-and has for an object to provide an improved packer especially adaptable for packing stock feed in sacks. v

Another object of the present invention is to provide an improved packer of simple construction adapted to operate quickly and efliciently, and wherein the feed or other material to be packed may be readily loaded into the machine, and the empty bags quickly put in place and after being filled quickly removed.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views: I

Figure 1 is an end elevational View, with parts shown in section of an improved packer constructed in accordance with the present invention.

Fig. 2 is a longitudinal vertical sectional view through the improved packer taken at right angles to Fig. 1, and showing in dotted lines the advanced position of theplunger.

Fig. 3 is a top plan view of the improved hopper.

Fig. 4 is a horizontal sectional view taken on the line H in Fig. '1.

gig. 5 is a plan view of the guide plate; an

Fig. 6 is a crosssectional view taken on the line 6-6 in Fig. 2.

Referring more particularly to the drawings, 1 designates a plunger of substantially elliptical form as shown in Fig. '6, fitted to move through an elliptical casing 2 having a delivery mouth 3 about which is arranged a double series of staggered pins 4 for receivin the mouth of a sack or other receptac e 5.

The side walls of the casing 2 are extended to form a hopper 6 havin the inclined bottom 7 which directs the fee or other material delivered thereto into the casing 2;

there is a cut-away portion 8 provided at the upper end of this hopper 6 in order to enable the operator to look in beneath the plunger 1 and ascertain the amount and height of the material in the casing 2, and to otherwise inspect the interior of the hopper and casing. The casing 2 and hopper 6 are supported in any suitable manner, preferably by braces 9 and 10, which are shown in Fig. '1 to diverge upwardly and be bolted or otherwise fastened to appropriate supports.

A piston rod 11 driven b a piston which reciprocates in a cylinder 12 disposed above the casing 2, is'threa'ded through a central and threaded opening in the plunger 1 and locked therein by a lock nut 13. The piston in the cylinder 12 is preferably composed of three steel disks l4: spaced apart by cupped leather washers 15, the ends of which bear against the cylinder walls. These disks 14 and washers 15 are, as shown in Fig. 2, fitted over the reduced end 16 of the piston rod 11 and held thereon by a nut 17. At its upper end the cylinder 12 is closed by a head 18 having a cylindrical flange 19 threaded to engage the threaded upper end of the cylinder 12. Brackets 20 are provided on the cylinder head 18 and cylindrical flange 19, and are adapted toreceive bolts or other fastening means 21 by which the upper end of the cylinder may be held on a support.

In like manner the lower end of the cylinder 12 is closed by a head 22 formed with the cylindrical flange 23 threaded on the lower end of the cylinder. This lower head carries a guide plate 25 'having openings 26 in any suitable number therein, and carrying thereon a bracket 27 which enables the lower end of the cylinder to be fastened to some object. The lower head 22 also carries a stufling box 28 containingpacking bag 29 surrounding the piston rod 11 and held in place by the gland 30. The heads of bolts 31 engage this gland 30 whereby to hold same in place, such bolts or screws being attached or threaded into the cylinder head 22. 7

Guide rods 32 provided in suitable number, corresponding to the number of the openings 26 in the plate 25, are slidingly fitted through said openings 26 and are attached to and movable with the plunger 1. For this purpose the plunger is preferably provided With small threaded openings to receive the lower threaded ends 33 of such guide rods 32. The purpose of the guide rod-s is to steady the plunger 1 as it moves through the casing 2.

A compressed air pipe 34 from a. suitable source of supply, is provided with the branches 35 and 36 leading respectively to the upper and lower ends of the cylinder, each of such. branches including shut- 01f cocks 37 and 38. A threeway or other valve 39 having operating means actuated by hand or automatically, is provided to turn the compressed air alternately into the up- 'per and lower ends of the cylinder 12 so as to reciprocate the piston.

The operation of the. invention is substantially as follows:

With the plunger 1 in the raised position shown in full lines in Fig. 2, the feed or other material to be packed is dumped into the open upper end of the hopper 6 and is diverted by the inclined wall 7 into the casing 2 below such plunger. This material passes freely through the delivery mouth 3 of the casing 2- and into the receptacle 5, which has been previously aflixed to the hooks or pins 4 in the manner shown. T he operator may constantly observe the height of this material, and when same rises to an appropriate level the deliver I of further material may be cut off to prevent overflow of the hopper and casing.

The valve 39 is now moved to direct C0111- pressed air through the branch pipe 35 into the upper end of the cylinder 12, the cocks 37 and 38 being normally open. This introduction of compressed air will drive the piston down, causing the plunger 1 to be also driven downwardly through the casing 2,

pushing before it the material, which it packs into the bag or receptacle 5.

The plunger 1 may be driven to any lowered position required. Generally it will be found desirable 'to drive it to substantially the position shown in dotted lines in Fig. 2, which will allow sufficient space above for the bringing of the mouth. of the bag together for tying. lVhen the bag is thus filled the valve 39 is turned to the position where it will allow the compressed air to pass through the branch 36, at the same time closing the branch 35, and compressed air will therefore be put into communication with the lower part of the cylinder 12, where it will become efiective to raise the piston and return the plunger 1 to the initial position at the top of the casing 2. The sack 5 is now removed fro-m the pins 4 and an empty sack substituted, whereupon the above described operations are repeated.

I claim:

In an apparatus having a casing, means whereby a receptacle to be filled may be supported with its mouth beneath the easing, and means traveling through the casing for driving material therein into the receptacle, the combination of a hopper formed by extending the side walls of said casing, the hop er bottom being inclined whereby to direct the material into the casing and through the delivery end of the latter, said hopper having a portion thereof cut away to enable the operator to look beneath said material driving means when the latter is in a retracted position, substantially as de scribed.

in testimony whereof, I affiX my signature.
