Specification of Letters Patent.

Patented May 27, 1919.

' Application ledwAurgust 20, 1915. Serial No. 46,445.

,F To all rwhom z't may concern:

, Be it known that I, FRANK HAMACHEK, a citizen of the United States, and resident of Kewauiiee, in the countyof Kewaunee and State of Wisconsin, .have'invented new and kuseful .Improvements in Pea-Separatore, of

ence being had to the accompanying drawings, which are a part of this specification;

This invention relates to pea separators which operate upon the crop of pea vines as .separated and vsubjecting them toblows of harvested and -by ykeeping the vines well rotating beaters causes theY pods to break `and liberate the green peas which are then sifted yfrom the pods and vines and immediately discharged to avoid'injury to them. The objects of the present invention are to improve upon details of construction of pea separators generally and particularly of the pea separator construction illustrated Vand described in my application for pea hullers and separators which resulted in Letters Patent No. 1035184,-dated Aug. 13, 1912.

' One of the objects of the invention is to provide stationary discharging fingers at the discharge'end of-the sifter drum Which eX- tend ,downwardly and obliquely from the Y' -fdischargeopeiiing of the drum in order to engage which may partially extend through the opening and thus coperate with the turning ofthe drum in drawingv vines 'out of the drum and preventing theirk accuf mulati'ng at the discharge opening.

@Another Vobject of the invention is to provide 'a slotted, grooved chute leading from :the discharge opening of the sifter drum with agitator wheelst'urning through the l "slots thereof toengage the tailings and lift them and shake them while they are somef what restrained in their travel by means of through thi'sfshakiiig andcombing out opera- "tion effect theseparation of such peas as thel tailings, the grooves of the chute aordm-ay have gone through the sifte-r drum with ing a} cl ear passagewayfor the discharge of fsiichpeas.'` QwAnother object of the invention is to im- 'prove upon details of'construction vof `the 4"tailings conveyer by :means of which l the i Y' iltailings are dischargedfrom the separator,

'whereby peas from thedischarge chute and frointhe tailings may freely roll down the tail'ing conveyer while the' tailings are be d thereby.

Another object ofthe invention is to improve upon various details of construction ofpea separators. y y

With the above andV other objects in view the invention consists in the pea separato-r as herein claimed andall equivalents.

Referring to the accompanying drawings in which like characters of reference indicate the same parts in different views: i g

Fig. 7 is a plan view thereof; Fig.8 is a view showing a modified form of toofth construction'. for the tailings cone veyer belt, and; Y Y

Fig. 9 is a plan view thereof. In these drawings 10 ,indicates a frameof any desirable construction-wliichhas ya shaft 11 journaled through it in bearings 12. This shaft carries a pulley 13 by means of which it may be driven from any suitable source ofpower. vletween thebearings 12 the'shaft hasmounted on' it ahe'xagonal or Vother-1desirably shaped body `portion 14 provided .with hiilling beaters 17which may bevaril l r ou'sly shaped vand are preferably oblique adjustable spring teeth above/the chute and with relation to the axis of the body porshaftv 11 cause them Vto actvv laspiropellers or fan blowers'for` causingfa. current of airto fiowiii theY .directionof the rear. or discharge end of the'pinachine wherethe pulley '-13 is located.

. Surrounding'thebody liti-with hulling beaters isa sievefdrum which has Vannular ends or heads 19 with metal bandsv or tracks 20 thereonwhich vrideon rollers 21 on the frame to support the dru m` within the frame and permit "it toirota-tef about the shaft 11 as its axis.V 'A rotary movementis givenv to the drum by means of chains@ which 'enf1 gage occasional lugs or sprocket teeth 23 on the heads 19 of the drum and which chains also travel around sprocket wheels 24 on a countershaft 25 which is journaled at the upper part of the frame and is driven from the shaft l1 by means of a sprocket wheel V26y on the shaft 25 connected by a chain 27 with a sprocket wheel 28 on said shaft 11. The direction of rotation of the drum is the same as the direction of'rotation of the hulling beaters, being the direction indicated by the arrow in Fig. 2, but its speed is much slower.

The end plates-L4 at the ends of the drum serve to confine the hulled peas to the space between them and fit close to the rings 19 as before and on the end plate 44 at the bottom of the discharge end of the sieve drum are secured a series of downwardly extending oblique teeth 85 which v`are so arranged as to readily engage a projecting portion of a bunch of vines while being carried around with the drum and as these teeth are stationary they tend to hold the vines while the drum turns away from t-hem,

thus assisting in the discharge of the vines from the drum. The teeth 85 being inclined are readily freed from the vines as the vines drop from the drum onto an inclined corrugated chute 86 below the teeth 85. The downward movement of the vines on the inclined chute 86 is restrained somewhat by the presence of a stationary inclined rake 87 which is adj ustably mounted on the frame at 88 to be capable of having its position changed to suit the requirements. The tines of rake 87 project toward the corrugated inclined chute 86 and serve to hold the vines if they are in large masses and subject them to the action of rotating combing wheels 89 therebeneath. The combing wheels 89 are mounted on a shaft 90 which is journaled across the discharge hopper 69 beneath the chute 86 and have backwardly turned arms or fingers extending therefrom reaching through slots in the upper or crest portions of the corrugated surface of the inclined chute 86 as shown in Fig. a. The action of these combing wheels 89 is to thoroughly comb out and separate the bunches of vines which are sufficiently large to be engaged by the rake 87 and thus liberate theV peas which may be entangled therein. Because of the corrugated surface of the inclined chute 86 the peas that are liberated readily sepay rate from the tangled vines and pass do-wn the trough portions of the corrugated surface. The inclined chute 86 discharges onto an inclined conveyer belt 91 which is in the form of an apron of canvas or other suitable material having slats 92 extending across it on its bottom surface to keep it in shape without forming shoulders for engaging and holding the peas which are discharged thereon by the inclined chute 86. In order that the vines may not slide down the conveyer 91, however, the Islats 92, have fingers 93 projecting upwardly from them through the apron and these fingers may be formed 1n tegral with metal slats as shown in Figs.

upper and lower ends of the conveyer 91- are provided with grooves 95 to receive the slats 92 and thus permitof the apron being kept tight at all times while also serving as a driving connection-between the Vpulleys and the apron. l

The operation of the pea separator of the present invention is substantially `the same as that of the structure covered by my copending application referred to. The peas liberated by the impactof the hulling beaters against the pods quickly find their way through the openings of the sieve drum and roll down the inclined apron 47 to the conveyer 50. Such peas as may be contained in the tailings, however, are more effectively recovered as the vines are more quickly ejected from the sieve drum by their engagement with the stationary teeth 85 and thusthe tendency ofthe vines to bunchlat the discharge end of theidrum is prevented, and the action of the comb wheels 89' in 'cooperation with the retarding rake 87 serves to entirely separate vines which may be tangled so that the peas held therein may be liberated and may pass down the grooves s ofthe inclined chute 86 on'tothe apron of the conveyer 91', the construction of the conveyer being such thatthis separation ofthe vpeas from the tailings is possible. While the vines are effectively carried upward by the conveyer 91 such conveyer presentsno hold the vines up offlof the chute surface and `assure free travel for the peas lon the chute. l

The guards as shown consist of spring rods, 100, preferably attached at their upper ends to the underside of the chute and extending downwardly and forwardly-at some distance above the chute. As stated the guardshold the vines away from the surface of the chute allowing the combing wheels 89 to get better action on the vines, thus securing better separation of the peas from the vines than when the guards are not present.

What I claim as new and desire to secure by Letters Patent is:

1. In a pea separator, an inclined chute for conducting vine tailings having its surface corrugated to form inclined vine conducting ridges and troughs into which loose peas may drop from the vines and be conducted separately from the vines.

2. In a pea separator, an inclined slotted chute for conducting vine tailings having pea conducting surfaces between the slots, means for restraining the passage of masses of vines down the chute, and combing wheels beneath the chute having arms passing through the slots'of the chute for separating the vines held by the restraining means to release peas contained therein.

3. In a pea separator, an inclined slotted chute for conducting vine tailings having pea conducting surfaces between the slots, an adjustable inclined rake positioned above the inclined chute for restrainin the passage of vines down the chute, an combing wheels beneath the chute having arms traveling through the slots of the chute for agitating and separatin the vines held by the rake to release peas t erefrom.

4:. In a pea separator, an inclined chute for conducting vine tailings and having a corrugated surface forming inclined troughs into which loose peas may drop and be conducted separately from the vines, said chute being provided with slots at the ridge portions of its corrugated surface, and combing wheels beneath the chute having arms traveling through the slots thereof for agitating the vines in theirtravel to shake the peas therefrom.

5. In a pea separator, an inclined chute for conducting vine tailings and having its surface corrugated to form inclined troughs into which loose peas may drop and be conducted separately from the vines, and inclined guard rods above the chute and approximately parallel therewith for holding masses of vines away from the surface of the chute.

6. In a pea separator, an inclined chute for conducting vine tailings, and inclined parallel guard rods above the chute for lifting the vines therefrom and holding them away from the pea conducting surface of the chute.

In testimony whereof, I aiiix my signature, in presence of two witnesses.

FRANK HAMACHEK.
