AFPLIGATIOH FILED APR-1. 1921. 1,381,797. Patented June 14, 1921 2 $HEETS-SHEET 118192201220; Cagoers:





' Application filed April 1,

improvements in stock sorters and particularly to devices for separating hogs of different sizes and ages.

One object of the invention is to provide a gate mechanism whereby the smaller hogs can readily pass through to the feed troughs, and whereby the larger hogs will be excluded.

Another object is to provide gates of this character which are readily capable of adjustment to compensate for the growth of the hogs.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings:

Figure 1 is a top plan view of the gates.

Fig. 2 is an elevation of the gates viewed from the entrance side thereof.

Fig. 3 is an elevation of the gates viewed from the exit side.

Fig. 4: is a horizontal sectional view taken on the line 4-14 of Fig. 2, which passes through one of the adjustable hinges of the smaller gates.

Fig. 5 is a vertical sectional view on the line 55 of Fig. 1, extending longitudinally of the roller support.

Referring particularly to the accompanying drawings, there is shown a frame including the base 10, the uprights 11, the upper horizontal cross member, 11'. A yoke 12 has its upper longer arm 13 disposed transversely of the intermediate portion of the member 11, and properly secured thereto, while its lower shorter arm 1a is secured to and extends transversely of the intermediate portion of the base 10. The outer end of the arm 14 lies almost flush with the edge of the bas 10, while the longer arm 13 extends outwardly beyond the corresponding edge of the member 11'. Carried transversely on the outer projecting end of the Specification of Letters Patent.

Patented June 14, 1921.

1921. Serial No. 457,573.

longer arm 13 is a member 15, and secured to each end of said member is a coil spring 16. Extending out from the outer end of the shorter arm it is an eye 17, while in the pro ecting end of the longer arm 13 there 1s formed an opening alining vertically therewith, as shown at 18, and disposed vertically through said openings is a pivot rod 19 on which is hung the large gate 20, said gate extending outwardly from the frame. Disposed vertically between the arms of the yoke, and having their ends journaled in the said arms, are the rollers 21, the same being disposed wholly within the frame. Carried by each upright 11, and on its inner vertical face, are hinges 22, the outer leaf 23 of which is longitudinally slotted at 24, and disposed against the inner vertical face of a door 25. Bolts 26 are disposed through each door and the slots of the hinges whereby the doors are capable of sliding adjustment to dispose their free edges at different distances from the rollers 21. Each door has extending from its free edge, both adjacent its upper end and its lower end, a bearing bracket 27, and journaled in each pair of brackets are the upper and lower trunnions of the vertical rollers, shown at 28. To the doors 25 are secured the other ends of the before-mentioned coil springs 16, said springs serving to pull and maintain the doors in closed position against the upper and lower stops 29, carried respectively by the member 11 and the base 10.

By sildably adjusting the doors through the medium of the slotted leaves of the hinges and the bolts 26, the distance be tween the rollers 28 and the rollers 21 can be varied so that hogs of certain sizes only, will be permitted to pass between the said rollers to the feeding troughs. The doors will swing freely, when the hogs pass out from the feeding pens. As the hogs grow, the doors are adjusted to accommodate the increased width of the animals. Thus hogs of certain sizes can freely pass back and forth past the doors, but hogs of large sizes will be excluded.

What is claimed is:

1. A stock separator comprising a frame, a main gate carried centrally by one side of the frame, movable doors mounted in the frame at opposite sides of the mounting of the main gate, and means for adjusting the doors toward and away from the said mounting of the main gate.

2. A stock separator comprising a frame, a vertical partition centrally within the frame, vertical rollers carried by the partition, doors movable in the frame at opposite sides of the partition, means for adjusting the doors toward and away from the partition, and a vertical roller on the free edge of each door.

3. A stock separator comprising a frame, a yoke mounted centrally in the frame and including an upper longer arm projecting beyond one side of the frame and a shorter arm projecting a short distance beyond the corresponding side of the frame, a main gate mounted on the projecting ends of said arms, vertical rollers journaled in the arms within the frame, hinged doors mounted in the frame and havingslotted hinges whereby the doors are adjustable toward and away from the said rollers, springs connected to the doors and to the projecting end of the longer arm, and a vertical roller mountedon the free edge ofeach door.

In testimony whereof, I affix my signa ture, in the presence of two witnesses.
