The lower portion of the one of the beveled faces 22, 23 and 24 is said magazine as seen from the front (Fig. effected by merely loosening the said wheels 40 1) is semi-circular in order that a circular 21 and 25 and moving them longitudinally bucketed feed wheel 4 (hereinafter particuof their respective shafts until the wheel 21 larly described) may be rotated therein with engages with the face required. to give the its circumference nearly in Contact Wl h desired speed of the bucketed feed wheel, the inner surface of magazine; and the said and then tightening the wheels by means 45 ortion as seen from the side, as in Fig. 2, f the set s rews in their hubs.

is tapered toward the bottom. By thls con- 27 i a ti l haft jo rn l d i th struction, the seed deposited in the magazine frame 1, and also in the magazine 3, which collects about the lower buckets of the feed receives its rotation from the shaft 17 wheel and in the rotation of the same are through the medium of gear wheels 29 and 50 entirely filled with seed. 30; and at its upper end it is fitted with a 5 is a hopper into which seed in bulk is head 31 to which the measuring cup 33 is thrown, the same having a pipe a leading attached in a manner hereinafter described. therefrom to the bottom of the magazine In the revolution of the measuring cup it where it is shaped to correspond with the passes under the funnel 9 and receives a 55 surface of the magazine at that point, as charge of seed which is carried over a chute 35 into which it is dumped by the inversion of the cup in a manner hereinafter described.

It is desirable that the seed measuring cup 33 should rest or slow up for a short period while under the funnel 9, to insure its being filled; and to obtain this stop, the gear wheel 29 is of the mutilated order, or devoid of teeth for a proper circumferential distance; and the space thus produced in the said wheel is arranged to meet the wheel 30 at the time that the measuring cup is directly beneath the funnel 9.

36 is a scraper preferably of sheet rubber, suspended from the side of the funnel 9 under which the filled measuring cup passes. By means of this device any seed in the cup which projects above its edge, is swept off before the seed is dumped into the chute 35.

To effect the inversion of the measuring cup so that it will dump its contents into the chute 35 and then right itself before again reaching the funnel 9 to receive another charge of the seed, the head 31 and the vertical shaft 27 are bored to receive the bar 37 in two parts 9 and h which parts meet at o. The upper part 9 of the bar 37 where it is contained within the head 31 is provided with rack teeth as shown in Fig. 4, and these teeth are in mesh with the teeth of a pinion 39 inclosed within a cavity in communication with the bore of the head. The shaft of this pinion extends laterally through the head and to its end is fastened an arm 40 which is secured to the stem 42 carrying the seed measuring cup. The lower end of the upper part 9 of the bar 37 is provided with a pin 43 which extends through a slot j in the hollow shaft 27, and upon the said shaft, and between the projecting ends of the pin 43 and the under-side of the upper bearing for the shaft which is formed as a part of the magazine, is coiled a compressed spring 44. The efiect of this coiled spring is to yieldingly hold down the part 9 of the bar 37 in its lowest position and retain the measuring cup during the main portion of its revolution in its upright position shown in Figs. 1 and 2, wherein it is adapted to receive seed delivered from the funnel 9, and carry the same to the chute 35 into which it is dumped by means of mechanism hereinafter described.

The lower end of the lower section it of the bar 37 is made polygonal and is guided by a properly supported bracket 45, and it is consequently not susceptible to rotation; and at a point between the said bracket and the beveled gear wheel 30 it is provided with rack teeth similar to those of the upper section 9.

47 is a toothed sector on a horizontal shaft 49 supported by the brackets 50 which also support the shaft 17, the teeth of which sector are in mesh with the rack teeth of the lower section it of the bar 37; and on the shaft 49 is also an arm 52 carrying a roller 0 which bears against a cam 53 on the shaft 17.

The shape of the cam 53 is such that as the seed measuring cup in its revolution reaches the chute 35, the bar 37 is suddenly lifted, the seed measuring cup inverted and its contents dumped into the chute. After the cup has discharged its measured quantity of seed to the chute 35, it is immediately righted, and upon again passing under the funnel 9 receives another supply of seed.

The lower end of the chute 35 is provided with a nozzle 55 adapted to receive an envelop held over it by hand, during the dumping operation of the machine.

56 is a hinged door in the front of the seed magazine to give access to its interior. In Fig. l the door is supposed to be open, the edge and the hinges only being shown.

57 is a sliding door which forms the bottom of the seed magazine 3, to be opened for the discharge of any seed left in the machine upon the completion of its operation.

The seed measurin cup 33 is extensible and contractible in efiective length to alter its capacity, by means of a movable bottom is held by a set screw which extends through a slot in the wall of the cup as shown in Fig. 5.

I claim as my invention,

1. In a machine for measuring and packaging seed, a seed magazine, a funnel, and a rotary bucketed feed wheel adapted to elevate seed from the magazine and discharge it into the funnel, combined with a chute, a seed-measuring cup with means whereby it is revolved in a horizontal plane and made to pass under the said funnel to receive seed from the same, and devices to invert the said cup and thereby dump its contents into the chute, substantially as specified.

2. In a machine for measuring and packaging seed, a seed magazine, a funnel, and a bucketed feed wheel to elevate seed from the magazine and discharge it into the funnel, combined with a chute, a revoluble seed measuring cup adapted to receive the seed from the funnel, mechanism whereby the said seed-measuring cup is inverted at the time that it is above or over the chute, and a feed hopper with a delivery pipe leading therefrom to near the bottom of the magazine, the said pipe being adjustable in height whereby the quantity of seed delivered from the hopper to the magazine may be varied, substantially as specified.

3. In a machine for measuring and packaging seed, a seed magazine, a funnel, a device to elevate seed from the magazine and discharge it into the funnel, and a chute, combined with a measuring cup, devices whereby the said cup is revolved horizontally about an axis which is exterior of the the funnel to insure of its being filled with seed, and other mechanism to effect the inversion of the cup while the same is over the chute, substantially as specified.

4. In a machine for measuring and packaging seed, a frame, a seed magazine which is supported by the frame, a funnel, a feed Wheel to elevate seed from the magazine and discharge it into the funnel, combined with a chute, a revoluble seed measuring cup, mechanism whereby the seed measuring cup is revolved about an axis, other means to invert the cup when the same is above or over the said chute, and differential gear wheels to drive the feed wheel, whereby the speed of the feed wheel with respect to that of revolution of the measuring cup about its axis can be varied, substantially as specified.

5. In a machine for measuring and packaging seed, a seed magazine, a horizontal rotary shaft carrying a bucketed wheel which is situated Within the magazine and adapted in its rotation to elevate and discharge the seed contained in the magazine, combined with a bevel gear wheel secured to the shaft of the bucketed wheel and adapted for adjustment toward and from the said feed wheel, the said gear wheel having a multiplicity of toothed faces of different diameters, and a vertical driving shaft carrying a bevel gear wheel having a single toothed face, which beveled gear wheel is adjustable longitudinally of the said shaft, whereby the teeth of the second wheel can be brought into mesh with the teeth of any one of the toothed faces of the first wheel, to change the relative speeds of the bucketed feed wheel and the driving shaft, substantially as specified.
