FEED-PACKER.

Specification of Letters Patent.

Patented Sept. 12, 1911.

Application filed August 19, 1909. Serial No. 513,712.

To all whom it may concern:

Be it known that 1, ROBERT MAXWELL, a citizen of the United States, residing at Peru, in the.county of Chautauqua and State of Kansas, have invented certain new and useful Improvements in Feed-Packers, of which the following is a specification.

This invention relates to feed packers, and my object is to produce apparatus of this character which will operate efiiciently, reliably and expeditiously, and by which feed may be packed at the desired density.

lVith this general object in view and others as hereinafter appear, the invent-ion consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which;

Figure 1, is a central vertical section of the lower portion of a feed packing apparatus embodying my invention with the movable parts in their initial positions. Fig. 2, is a side elevation of the complete apparatus on a smaller scale than Fig. 1. Fig. 3, is an enlarged cross section taken on the line 111-111 of Fig. 2. Fig. 4, is a top view of the upper part of the apparatus. Fig. 5, is a side view of the upper part of the extension rod of the machine in its elevated and inoperative position.

In the said drawings, 1 indicates a chute leading through a floor 2 to a bin 3 mounted upon a suitable frame l and provided with a cylindrical discharge spout 5 provided, by preference, with an external groove 6 and with a plurality of inwardly projecting pins or shoulders 7 above said groove as a means.

of limiting the downward movement in the spout of an inverted hollow truncated cone 8, which in practice forms a tapering or diminished mouth for the spout. Underlying and of slightly larger diameter than the spout and suitably supported is a cylindrical casing consisting of a semi-cylindrical stationary portion 9 and the semi-cylindrical hinged door 10, any suitable latch mechanism 11, not detailed because of its unimportance, being employed to secure the door in its closed position.

12 is a sack adapted to be fitted over the lower end of the spout 5 when the door 10 is opened and secured by a clamping ring 12 or equivalent device, in the external groove of the spout.

13 is a reciprocatory rod arranged centrally in the spout and extending up through the bin and floor 2 as well as other floors if desired, in fact it is preferred that said rod shall be of suflicient length to extend up through the topmost floor of the mill equipped with the apparatus, the rod being guided near its lower end in a cross bar or other guide 14: and near its upper end in any suitable manner, not shown, cross bar 14: forming a support for a cushion 15, which is preferably in the form of a helical spring. The rod .is provided with a collar or enlargement 16, and said floor has an opening 17 of suficient size to permit the collar to pass through it. The rod also carries a smaller collar 17 capable of passing through an opening in a bracket 17 secured on floor 2 and a weight 17, the latter fitting slidingly on the rod and incapable of passing through the opening of said bracket. d

When the apparatus is in its initial position the collar 16 is supported upon a catch 18 pivoted on a bracket 19 and held yieldingly in the path of vertical movement of said collar 16 by a spring 20, a. lug 20 project-ing from the bracket 19 preventing catch 18 from being pressed far enough to conflict with the collar 17 (See Fig. 2.) A cable 21 guided over a sheave 22 is connected to said catch at one end and at its opposite end to a lever 23 mounted on frame 4 within convenient reach in order that an operator may withdraw the catch and permit the rod to drop downward until the collar 16 is arrested by the cushion or by the contact of the plunger 2a with the bran or other feed being packed into the sack.

The plunger 24 is preferably of truncated conical form and secured on the lower end of the rod 13 and is adapted when elevated to form a cut-off or closure for the tapering mouth 8 of the spout 5, and said plunger is provided with a plurality of channels 25 through which air may pass upward in the downward movement of the plunger as the bran or other'feed which passes down into the sack when the plunger starts downward will be in suflicient volume to practically fill the space between the exterior surface of the plunger and the sack and unless means were provided for the upward passage of the air,

the latter would in a measure retard the descent of the plunger and interfere with the free descent of the feed, as will be readily understood.

At its upper end the plunger rod 1.3 is

- equipped with a pivoted extension rod 26 provided with a plurality of spaced pins 27 so asto constitutea rack bar, and said rod 13 and its extension 26 are provided at oppoa cam arm 34 adapted to successively engage the pins 27, for a purpose which hereinafter appears.

Secured on a timber 35 or its equivalent 2 adjacent to the belt wheel, is a bracket 36 having inclined arms 37 at opposite sides of extension 26, terminating in flanges 38 interposed between the extension and the shaft 31, to limit movement of the former toward the latter under the pressure of spring 30,

and the extension rod is also provided with a pin 39 adapted when the plunger is at its highest point to be forced by a guide arm 37 of the bracket 36 or its equivalent, outward from the shaft and thus hold the lowest pin 27 out of the range of action of the cam arm 3t-as shown in Fig. 5.

When the plunger is elevated as shown in Fig. 1, it is held in such position by the catch 18, and at such time the pin-equipped rod extension 26 occupies the position shown in Fig. 5.

Assuming that it is desired to charge the sack with feed, not shown, contained in the hopper or fed continuously thereto when the machine is in operation, through chute 1, the lever-.23 is pulled downward to permit the plunger and the part-s connected thereto,to drop downward as hereinbefore explained, until the collar 16 is arrested'by the cushion 15. The belt is then started and the shaft rotated in the direction indicated by the arrow Fig. 2, it being. understood that as soon as the plunger dropsfa charge of feed passes through the reduced mouth 8 of spout 5 into the sack, and it will also be noted that when the plunger drops, spring 30 swings the rod extension 26 toward the shaft until arrested by the flanges 38 of guide bracket 36 so that as the cam arm starts upward it will engage the topmost pin 27 and thereby lift the plunger until said cam arm becomes disengaged with said pin, which in practicewill preferably be about an eighteen. inch lift; In this lifting operation a quantity of the feed will pass down around the plunger to the bottom of the sack. As the cam arm passes out of engagement with said pin, the plunger will drop and the air will pass up through the channels 25 and thus avoid agitating or blowing the feed upward around the plunger. In the next revolution of the cam arm it may reengage the same pin and again lift the plunger, but if it does engage said pin the second lifting operation will be somewhat less than the first because the feed in the bottom of the sack will prevent the plunger from moving downward to its extreme limit of movement as when the sack is empty. In practical operation the cam arm may engage said pin two or three times and eventually the plunger will be elevated until the cam arm engages the next lower pin. These operations are repeated until the undermost pin is engaged and lifted by the cam arm, by which time the sack will be full of packed feed, the final engagement of the cam arm with the undermost pin causing pin 39 to slide upward and outward against guide arms 37 for the purpose of disposing the undermost pin 27 out of the range of movement of the cam arm. The door 10 may then be opened and the sack removed and replaced by an empty one, after which the door is reclosed and the described operations repeated. It will thus be seen that a sack can be rapidly, efliciently and reliably filled.

In the operation of the apparatus collar 17 is functionless if heavy feed is being packed, as in such case the weight 17 will be removed from the plunger-rod. Where the feed is light and it is desired to pack it as tightly as possible in a sack, the weight 17 c is slipped upon the rod, so that each time the plunger is raised, the small collar 17 passes up through the bracket 17 b and lifts the weight, to utilize the same for causing the plunger to move downward with greater force than usual. The weight is arrested by the bracket 17 just before the collar 16 strikes the cushion 15, which is thus relieved of the strain incident to arresting the downward movement of the weight. After sufficient feed has been packed in the sack to check the downward movement of the plunger before the collar 16 strikes the cushion, the power of the downward stroke of the alun 'er will be increased because the )lun er will not move downward a sufiicient distance for the weight to come in contact with the bracket 17 b as will be readily understood.

It is obvious that the size of the weight 17 may be varied and that the density of the packed feed maybe diminished or increased by adjusting collar 16 downward 01' upward respectively, on rod 13.

From'the above descriptionv it will be ap-' parentthat I have produced a feed packer embodying the desirable features enumerated and I wish it to be understood that I do not desire to be restricted to the exact details ofconstruction shown and described as obvious modifications will suggest themselves to one skilled in the art.
