ARTHUR ELPHINSTONE CUMMINS, OF LONDON, ENGLAND.

BALING-PRESS.

Specification of Letters Patent.

Patented May 16, 1911.

Application led November 4, 1910. Serial No. 590,681.

To all whom it may concern:

Be it known that I, ARTHUR ELPHIN.- STONE CUMMINS, a subject of the King of Great Britain, residing at 58 Belsize Park Gardens, London, England, have invented new and useful Improvements in Baling- Presses, of which the following is a specification.

The press forming the subject of this invention is a horizontal endway press with one very long filling box having doors throughout its whole length and large enough to take loose cotton thrown into it without any manual pressure suflicient to form a whole bale; at one end of the box is lixed a condensing chamber and at the end of this chamber is attached a powerful cylinder in which works a double acting ram which by means of a multiple rope gear attached to it gives on its return stroke the preliminary pressure required to pull the loose cotton into the chamber; the ropes actuate a follower traveling inside the filling box and are attached to horns on the follower which horns project through slots in the bottom of the filling box. In this way a loose cotton filling box of very large capacity can be provided at a very low cost, and the cylinder, ram and other gear formerly used for forcing loose cotton into the chamber are entirely dispensed with thus greatly reducing the first cost of the press while the size of the building necessary for the press is also much reduced.

The details of construction of my press will be more readily understood from the drawings accompanying this specification so I will at once proceed to describe them.

Figure 1 is a part vertical section of a baling press made in accordance with my invention, Fig. 2 is a cross section (to a larger scale) on the line A-A Fig. 1, while Fig. 3 is a part plan. Fig. 4 shows details of the box to a larger scale. Figs. 5 and 6 show details of the valves to a larger scale.

1 is a long box or trough, the greaterpart of which is broken away, the extreme ends only being shown. Fig. 4 is a cross section of the box to a. larger scale and Fig. 5 is a side view of a. portion thereof.

The box is formed of plain steel plates 2 on each side, back and front, the whole length of the top being formed of a series of doors 3 (shown open in Fig. 1 and closed in Figs. 3 and 4); the bottom consists of channel and angle irons 4 only, as seen in Fig. 4, running longitudinally the full length of the box; these plates, channels and angles are retained in place by square binding T-brackets 5 between the doors so that the box is perfectly ri id when erected in working order. Each door 3 is carried by eccentrics G on a shaft 7 so arranged that the first movement of rot-ation imparted to the shaft by any convenient means such as an arm fast thereon causes the door to slide toward the shaft thus withdrawing its front edge from beneath a shoulder 8 on the top of the box (see Fig. 4). As soon as the door has thus been freed, a counterbalance weight 9 secured to it turns it back upon its hinge.

In the box runs a follower 10 provided with wheels 11 and having horns 12 projecting downward through the bottom of the box 1. On to these horns are looped ropes 13 which pass to multiple pulley blocks 14 on an axle 15 carried by wheels 16 running on a track 17. This axle is moved to and fro by a rod 18 connected to a ram 19 moving in a hydraulic cylinder 20. From these moving blocks the ropes pass to blocks 21 secured to the cylinder. Though the follower might be actuated by a single rope arranged in the middle of the press, I prefer to use two ropes and two pairs of pulley blocks one on each side as shown.

It will be seen that when the ram moves to the left the pulley blocks 14 move away from the blocks 21 thus pulling on the ropes and moving the follower 10 also to the left. When the ram moves in the opposite direction, the follower is also moved to the right (keeping the ropes 13 taut) by a rope 22 passing out at the right hand end of the box and over pulleys 23 on a standard 24 and so to a weight 25. During this last movement of the follower and while it is at rest in its extreme right position, loose cotton is thrown into the box 1, the doors of which are then closed, and on the ram being moved to the left the follower 10 pushes the cotton before it into the condensing or baling chamber 26. This chamber consists simply of two main steel sides 27 coupled to the cylinder 20 by means of projecting horns 28, those on the sides and cylinder end being bound together by strong steel hoops 29 shrunk on hot, eight horns in all being coupled in twos in this way; the two steel sides form the back and front of the chamber, and between them to form the top and bottom steel and iron plates are inserted under lugs lcast on the main steel sides, the whole being bolted together by through bolts from main side to main side. In the sides are fitted strong doors 30 for hooping andreleasing the bale in the usual way. The top releasing door 31 opensv in a much easier and more gradual manner than formerly, by reason of being set on two eccentrics 32, and this is of great advantage insomuch that the bale is allowed to expand gradually as it is being condensed on four sides, instead of two as formerly when held rigidly until nished before releasing the top door, a large economy in power is thus effected. The opening of the door may be effected automatically as hereinafter explained.

When the follower 10 has reached the end of its travel to the left a grid 33 passes into and across the press and when it is in position water is again admitted to the cylinder as hereinafter described and the ram is caused to move to the right compressing the bale. rllhe grid takes the full pressure of the ram, vbeing supported by the main sides 27 of the condensing chamber. The grid is preferably moved in and out by means of a quick screw 34 and hand wheel 35, see Figs. 2 and 3, butit may be moved by any other convenient means.

If desired, and as has been already indicated, the doors of the baling. chamber may be opened automatically as follows: As the ram is nearing the end of its stroke to the right' a lump 36 on the rod 18 cornes against a bell crank 37 connected to a bar 38 linked to arms 39 on the Ashafts 40 carrying the eccentrics 32 so that the movement of the ram turnsthese eccentricsY and releases the top door 31. The bar 38 may also be connected to arms 41 on pins 42 which lock andunlock the side doors 30'. Preferably alsoI so arrange the valves governing theY supply of water to the cylinder 2O that the'pressure shall be automatically cut 0E when the ram reaches a predetermined position. With this object I may use the valves shown in Figs. 6, 7 and 8. I'nthis arrangement water enters the valve box 43 by the port 44 and can flow bythe 'passage 45 past the screw down valve 46 to the port 47 leading by the pipe 47X to the left hand end of the cylinder and also by the passage' 48 past the screw down valve 49 to the port'50 leading by the pipe 50X to the right hand end of the cylinder.

Branches 51, 52 leadfrom the passages 45', 48 to waste valves 53, 54. In addition a relief valve 55 is arranged in such a way that when' it is open the pressure water flows directly to waste. This relief valve is op-A erated by aV lever 56 so weighted that the valve is normally closed but it can be opened as follows: When the ram hasarrived almost atthe end of its travel to the right the lump 36'comes against and rocks a lever 57 which pulls a rod 58 rockingv a lever 59 and so pulling a rope 60 connected to an arm 61 on the lever56 and so opening the relief vvalve 55 and stopping the supply of water to the left hand end of the cylinder. The ram is stoppedA at the end of its return stroke by part of the follower 10 coming against a bell crank 62 linked by a rod 63 to a bell crank 64 also connected by a rope 65 to the arm 61. Y. It is obvious that by altering the length of the ropes 13 the travel of the follower 10 and consequently the point at which pressure is cut off from the right hand end of t-he cylinder and therefore the stroke of the ram may be altered. This is of great advantage when baling material such as hemp or jute that requires greatly less filling box `capacit-y than Afor cotton, much less working expenses being incurred, for the ram will be using considerably less pressure water, and the speed of baling will be increased.

The valves 46 and 49V are able to move slightly up and down on their stems so that they will allow water to pass them to the cylinder but as soon as the pressure is relieved they drop by their own weight so imprisoning the water in the cylinder before they are screwed down and stopping'the ram dead. As will bp seen from Fig. 1 there is a large difference between the areas of the two sides of the ram, the larger or more powerthe full power of the ram can be at once turned on to the material by simply opening the valve 54.

The action of the press is as follows The ram is run full out andthe balance weight withdraws the filling box follower 10, the filling box is then filled with loose cotton by means of the filling doors, and theV ram retired, .which thus draws the loose cot` ton'mtc the condensing chamber, the grid is then inserted and the ram runout; as the i ram runs out the follower 10 retires leaving the filling box empty and readyfor more cotton for the next bale, as soon as the'lash- Y ing doors back and front open, the'bale is lashed and the ram is retired, and the bale thrown out, the doorsV are closed andthe grid withdrawn, the rope gear commences to act and draws up the farthercotton yfor a subsequent bale, and so on. v

l/Vhat I claim is V1. In a baling press,the combination of a condensing chamber, a hydraulic cylinder at one end of the condensing chamber, a ram in the cylinder, a filling box at the other end of the condensing chamber, and mechanism whereby the movement of the ram in one direction forces the loose material from the filling box into the condensing chamber while the movement of the ram in the other direction compresses the material in that chamber.

2. In a baling press, the combination of a condensing chamber, a hydraulic cylinder at one end of the condensing chamber, a ram in the cylinder, a filling box at the other end of the condensing chamber, a follower in the filling box, and rope gearing connecting the follower to t-he ram so that the movement of the ram in one direction causes the follower to force the loose material from the filling box into the condensing chamber while the movement of the ram "in the other direction compresses the material in that chamber.

3. In a baling press, the combination of a condensing chamber, a hydraulic cylinder at one end of the condensing chamber, a ram in the cylinder the effective area of the two sides of the said ram being dierent, a filling box at the other end of the condensing chamber, and mechanism whereby the movement of the ram in one direction forces the loose material from the filling box into the condensing chamber while the movement of the ram in the other direct-ion compresses the material in that chamber.

4. In a baling press, the combination of a condensing chamber, a hydraulic cylinder at one end of the condensing chamber, a ram in the cylinder the effective area of the two sides of the said ram being different, a filling box at the other end of the condensing chamber, a follower in the filling box, and rope gearing connecting the follower to the ram so that the movement of the ram in one direction causes the follower to force the loose material from the filling box into the condensing chamber while the movement of the ram in the other' direction compresses the material in that chamber.

5. In a baling press, the combination of a condensing chamber, a hydraulic cylinder at1 one end of the condensing chamber, horns on the condensing chamber, horns on the cylinder, and means for binding together the two sets of horns.
