PEA THRESHER AND SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 566,571, dated August 25, 1896.

Application filed July 30, 1895.

To aZ/I whom it may concern-.-

Be it known that I, DAvII) A. GAITHER, a citizen of the United States, residing at Williston, in the county of Fayette and State 01": Tennessee, have invented a new and useful Pea Thresher and Separator, of which the following is a specification.

This invention relates to machines for hulling, separating, and purifying peas and beans, and has for its object to provide a mechanism for performing the required work in a thorough and efiective manner and with the expenditure of a minimum amount of energy.

Other objects and advantages will be apparent as the nature of the invention is understood, and to this end reference is to be had to the following description and the drawings hereto attached, in which Figure 1 is a perspective view of a machine constructed in accordance with the present invention. Fig. 2 is a vertical central section thereof, the dotted lines showing the movable or intermediate hopper partially drawn out. Fig. 3 is a top plan view of the machine with the upper hopper removed. Fig. 4 is a detail section of the upper portion of the machine about on the line X X of Fig. 3.

The framework, which will be a substantial structure, may be of any approved construction for conveniently supporting the operating parts, and is shown as comprising cornerposts 1, upper and lower side beams 2, and The hullin g or threshing cylinders 4: are of similar con struction and are arranged in parallel relation and are journaled in bearings on the upper side beams 2. The teeth 5 are arranged spirally upon each cylinder, the spiral arrangement of the two cylinders being in inverse order, whereby in the operation of the machine the peas or beans to be threshed are moved in one direction by one of the threshing-cylinders and in an opposite direction by the other threshing-cylinder.

The two threshing-cylinders are spaced a proper distance apart, and a semicircular riddle 6 is placed beneath each. These semicircular riddles 6 have their edge portions outwardly flanged and overlapping the upper cross-beams 3 and an intermediate cross-beam 7, and by means of which the said riddles are Serial No. 557,603. (No model.)

held in proper position. These semicircular riddles are formed of sheet metal, and the series of openings formed therein are of a size to admit of the passage of the peas or beans, and the semicircular form thereof admits of the teeth of the threshing-cylinders sweeping close to the upper sides of the said riddles when the machine is in operation.

Rows of teeth 8 extend inwardly from the opposite edges of the riddles and are supported by the upper and intermediate crossbeams. In order to give strength to the rows of teeth 8, the latter pass through openings near the edges of the riddles and are let into the wooden cross-beams of the framework, and in order to facilitate the threshing process the teeth 8 incline slightly to the horizontal. The teeth of the threshing-cylinders and the rows of teeth 8 are so disposed that the teeth of the said cylinders will operate about midway between the teeth 8, thereby breaking the pods or hulls and liberating the peas and the beans.

The upper hopper 9 is removably fitted upon the framework and has a horizontal partition 10 a short distance above its bottom edge, and which forms a bottom thereof, and a discharge-opening 11 is located in the horizontal partition or bottom 10, so as to come directly over one end of a threshing-cylinder. A series of strips 12 and 13 are secured to the under side of the partition or bottom 10, the middle strip 12 coming directly over the intermediate cross-beam 7 and having a space 14 at the end opposite the opening 11 to admit of the peas and beans passing from one cylinder to the other in the working of the machine. The side strips 13 come directly above the upper cross-beams and serve to retain the peas in engagement with the teeth of the threshing-cylinders.

Immediately below the threshing-cylinders 4 are located a fan 15 and a supplemental threshing-cylinder 16, the fan and the threshin g-cylinder being arranged in the same plane and located side by side. Side pieces 17 close the ends of the fan-case and form an inclosure-for the threshing-cylinder 16. A vertical wall 18 extends between the fan and the threshing-cylinder l6, and its lower portion curves forwardlyand upwardly and is provided with a series of openings, and consti- V V l 1 i l i f 3 a; inner: end terminates iinrmediatelybelowithe l r j i h agecylincler :16 ancli approaches :eiose I tutes asemicireu'lar riddle 19 for: the ethre'shi-z V hug-cylinder; 16 1A cross-bar'20, made fast operate- :in; the; spaces between the teeth; '22,

WVhen it is required to gain access to the upper riddles or the lower threshing-cylinder, the hopper 25 is drawn out and said parts are exposed and the obstructing matter can be quickly removed. This slidable feature of the hopper 25 upon its supports 26 and 17 also admits of the lower or supplemental threshing-cylinder being thrown out of operation when desired, as will be readily understood on reference to the dotted lines in Fig. 2. A door 27 is hinged to the lower end of the hopper 25 and closes against the crossbar 20, thereby completely inclosing the threshing-cylinder 16. This door 27 forms, in effect, a movable side to the housing, which closes the upper portion of the riddle 19 and threshing-cylinder 16 and admits of access being readily had to the riddle and threshin g-cylinder for removing obstructing matter, for cleaning the riddle and threshing-cylinder, and for making repairs when required. The thresher may be operated by manual or other power, and for this purpose a journal of one of the threshing-cylinderseiis supplied with a crank 28, and the opposite jour nal carries a fly-wheel 29 and a sprocket gearwheel 30, which transmits motion 'to a support for one edge of the-riddle I9, andis provided with; rowrof teeth 21 avhich no operate with the teeth '22iof tl 1e threshing eylinder 16,; so as to breakup any pods or hulls which, may Zhavoeseaped ite tho snpplei 1 mental threshing mechanism.

The pods or hulls of the first or initial riddle are transferred to the second threshing-cylinder by means of the teeth of the first or initial threshing-cylinder, and in order to make provision for the escape of the said hulls or pods from the first riddle a number of the teeth 8 at the inner end of the inner row are omitted opposite the space or opening 14, as most clearly indicated in Fig. 3. The peas or beans after escaping from the riddles 6 are subjected to a second threshing by means of the cylinder 16, and after leaving the riddle 19 they are subjected to a blast of air which carries off all small particles, thereby permitting the peas or beans to be received into a receptacle thoroughly cleaned and freed from all foreign matter.

A machine of the character herein set forth can with slight modifications be adapted for factory or domestic use, and in constructing the same for the particular requirement it is to be understood that changes in the form, proportion, and minor details of construction may be resorted to without departing from :10 the principle or sacrificing any of the advantages of this invention.
