SPECIFICATION forming' part of Letters Patent No. 717,826, dated January 190g.

Application Jfiled May Sl, 1902. Serial No. 109,766. (No model.)

To @ZZ whom, t may concern.:

Be it known that l, CHARLES W. ELL'Is, a citizen of the United States', residing at lndianapolis, in the countyof Marion and Statev of Indiana, have invented certain new and useful Improvements in Packers, of which the following is a specification.

My invention consists in certain improvements in packers, and has for its objecta means for packing allr kinds of fluffy homogeneous material, such as bran, iiakes, dto.

The object consists, further, in providing a packer having a movable platform lwhich carries a plate mounted in ways to which the casing which incluses the sack is secured, a cylinder through which the material is fed into the sack, a reciprocating plunger working within said cylinder, and a chute connecting with the cylinder through which the material is fed, the said chute being provided with a valve which is operated by a crankarm secured to the shaft to which the valve is secured, the said crank-arm having an upright pivotally secured thereto, which is formed into a hook on the upper end and which hook engages with an arm on the plunger-beam, and through which construction an alternating movement is imparted to the valve, thus discharging the material to be packed into the cylinder in an alternating manner.

There are other features, and the construction and arrangement of the several parts will he hereinafter more particularly described, and then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof and on which similar numerals of reference indicate similar parts, Figure 1 is a front elevation of my packer and shows the movable platform in its lowest position. Fig. 2 is a side elevation of the construction shown in Fig. l. Fig. 3 is a central vertical section of the pac ker, on a considerably-enlarged scale, and shows the platform raised and enveloping the cylinder, in this figure the uppermost or driving mechanism of the packer being broken away. Fig. a is a side elevation of the lower portion of the packer with the platform raised and also showing the manner in whichthe movable platform actuates the mechanism for operating the valve in the chute.

Fig. 5 is a horizontal sectional vieur of the packer and shows the platform in plan view. This figure also shows how the casing is adjustably secured to 'said platform. Fig. 6 is a fragmentary detail, on an enlarged scale, of the vise-shaped clutch mechanism which regulates the downward movement of the platform, as well as determining the pressure on the material by the plunger; and Fig. is a fragmentary detail in elevation of the plat= form and shows the manner of inserting the adjustable block that forms the base when packing material into barrels.

In the drawings, 1 represents the uprights of the framework of the packer which forms the guide for the platform.

2 is the movable platform. The platform 2 is provided at each end with a standard 3, which stands vertically with and against the uprights 1 of the frame. The standards 3 are provided with the yokes 4, which extend across the face of the uprights 1 and keep the two parts in alinement. The yokes also form a bearing for the vertical rods 5, which are secured to the platform 2 at the bottom and have an eye at the top, to which the chains 6 are secured. The chains 6 extend upward and engage with the grooved` wheels 7 by means of the lugs 8 and hooks 9.

The packer is provided at each side with one of the grooved wheels 7, which are mounted on the transverse shaft '10, suitably secured in bearings in the framework of the packer. On each side of the packer and mounted on the transverse shaft 10 and adjacent to the grooved wheels 7 are the balance- Wheels 11,having a grooved periphery, which form a seat for the cables 12. Each of the wheels 11 has a cable 12 secured thereto, each of which has a balance-weight 13 secured to the suspended end. The balance- Wheeis 11 are each provided with a frictionclutch which regulates the downward movement of the platform, and on the release of the said clutches, which will be hereinafter described, and under the tension of the weights 13, as previously described, the platform 2 is raised. The movement of the platform also regulates the amount of compression exerted by the plunger on the material being packed. Each friction-clutch is formed like a vice composed of the jaws 14.

and 15, between which the wheels pass. The jaws 14 and 15 of the clutches are mounted on the threaded stud-shafts 16, each of which is secured to a suitable base fixed to the framework of the packer. A coil-spring 17 encircles each of the shafts 16 between the jaws of the clutches. The springs have a tendency to relax the pressure of the jaws on the wheels 11 when the lower ends of the jaws are actuated. The shafts 1.6 are provided with the hand- wheels 18 and 19, one of which regulates the longitudinal movement of the jaws, while the other acts as a jamnut. The lower ends of the jaws 14 are provided with grooved friction-wheels 20, while the jaws 15 carry the cams 21, which engage with said friction-wheels. The cams 21 are mounted on the shafts 22, which extend to the rear of the framework 1. The shafts 22 have the crank-arms 23 secured to the rear ends thereof and which are connected together by the connecting-rod 24. One of the shafts 22 extends forward and has the crankarm or hand-lever 25 secured thereto,so that on actuating the hand-lever 25 the shafts 22 and clutches are operated sim ultaneously through the connecting-rod 24. When the wheels 11 are released from the clutches, the weights 13 cause lthe platform to rise. To limit the upward movement of the platform, I secure the stops 28, having a flexible cushion, to the side of the nprights 1 of the framework of the packer. When the platform rises, it envelops the vertical cylinder 27, which is secured at its upper end in the frame 1. The platform rises until the floor thereof is approximately twelve inches from the lower end of the cylinder 27, which provides ample room for the first discharge of the material, and hence no descent of the platform takes place on the first compression. The upper end of the cylinder 27 is closed. A plungerbeam 29 passes through the cover of the cylindex' and has the plunger-head 30 secured thereto, which compresses the material. The upper end of the plunger-beam 29 has the guide-strips 31 secured thereto, which strips engage with the xed guide 32, which guide prevents any lateral movement of t-he upper end of said beam. A pitman 33 is pivotally secured to the beam 29, which pitman is secured to the crank-arm 34 on the shaft 35, and through the shaft 35, gear-wheels 36 37, and the pulley 38 the plu nger-beam 29 is operated.

A chute 39 connects with the cylinder 27, through which the material is fed. The chute 39 is provided with a valve 40, mounted on the transverse shaft 41. The shaft 41 has a crank-arm 42 secured to each end. The arm 42 on one end of the shaft carries the weight 43, (see Fig. 1,) which insures the closing of the valve. The valve 40 is actuated by connecting the upright 44 to one of the crankarms 42. The upright 44 has a hook 45 formed on the upper end thereof, which stands in the path of and engages with an arm 46, secured to the plunger-beam 29. The arm 46 on the plunger-beam comes into contact with the hook 45 on each upward stroke of the plunger, which contact opens the valve 40' in the chute. The upright 44 is made in two parts and can be adjusted so that the hook will engage with the arm 46 at a desired point, and thus determines not only the throw of the valve 40, but regulates the amount of the discharge. It will be readily seen that through this construction I can procure a discharge of various amounts, which is one of the main features of this invention. I may also state that the contact of the arm 46 on the plungerbeam and the hook 45 is near the terminus of the upward stroke of the plunger-beam, the valve 40 opening when the plunger-beam is above the egress of the chute 39.

The upright 44 passes through a horizontal sliding plate 48, which plate is mounted in ways cut in rthe sides of the box or trough construction 47, which is fixed. (See Fig. 4.) The sliding plate 48 when actuated, and which will be hereinafter described, moves the upright 44 into or out of the path of the arm 46 on the plunger-beam. The upright 44 normally stands in the path of the arm 46 under the tension of the spring 49 during the time the valve 40 is being operated, and only when the upright 44 is thrown out of contact with the arm 46 is the valve 40 at rest, the reason for which will be hereinafter fully described.

It willbe seen by examining Figs. 2 and 4 of the drawings that an uprighty 50 extends from the lower end of the packer near the door up to a point immediately above the box 47, where it terminates. This upright 50 passes through the sliding plate 48 in the same manner as the upright 44. The upright 50 is pivotally connected to the framework of the packer at the pivotal bearing 51. The upright 50 is provided with two cams or inclines 52 and 53. The cam 53 is made integral with the upright, while the cam 52 is secured in an adjustable manner by the overlapping plate 65, carrying the slots 54, through which the bolts 55 pass. The upright 50 is actuated by the cams 52 and 53 coming in contact with ears secured on the movable platform 2 and standard 3. When the platform ascends or descends, the ears thereon actuate the upright 50, and through the sliding plate 48 the upright 44 is either thrown into or out of contact with the arm 46, secured to the plunger-beam. Thus it will be seen that the platform actuates the upright 50 automatically, which in turn moves the upright 44 into engagementwith the arm 46 on the plunger-beam and through which construction a reciprocating movement is imparted to the upright 44, and through the crank-arm 45, which is pivotally secured to the lower end of the upright 44 and the valve-shaft 41, the valve 40 in the chute 39 is oscillated.

One of the standards 3 of the movable platform 2 is provided with an ear 56, rigidly secured thereto, and which engages with the IOO IIO

cam 53 on the upright 50 on the ascent of the platform and moves the upright from the dotted lines in Fig. 4 to the position occupied by said upright in full lines. This moves the upper end of the upright 50 backward, and through the sliding plate 48 the upright 44, which is pivoted below the plate 48, is moved until the hook 45 on the upper end stands in the path and is actuated by the arm 46 on the plunger-beam 29. The platform '2 is provided with a second ear 57, which comes into contact with the cam 52 on the lower end of the upright 50 and which contact moves the upright in `the opposite direction from the previous operation, which also moves the upright 4:4 out of contact with the arm 46. This last operation takes place when the platform has reached the end of the downward -movement, at which time the valve 40 is at rest and no material being discharged. When the platform has reached the bottom, the sack in which the packing has taken place is lled and not until the full sack is removed and replaced by an empty one and `the platform has risen to the terminus of its upward movement, at which time the ear 56 onl the standard 3 comes into contact with the cam 53, when the valve 40 is again thrown into operation. It will be noted, however, that I in no wise interfere with the operation of the plunger, which in my packer is constantlyin motion. Pivoting the upright 50 between. the cams 52 and 53 provides a means for actuating said upright in both directions, as has been previously described.

In Fig. 5 of the drawings I have shown the casing 26 secured to a sliding plate 58, which plate slides in the ways 59, secured to the platform 2. This construction provides -a means for removing said casing and replacing the' same by casings of various sizes or by substituting a block that forms a base when I desire to pack into barrels. (See Fig. 7.) Y
