FEEDlNG ATTACHMENT FOR THRESHlNG-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 569,588, dated October 13, 1896. Application filed October 18, 1895. erial No. 566,130. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE WAsHINeToN RUCKER, of Belle Plaine, in the county of Benton and State of Iowa, have invented certain new and useful Improvements in Feeding Attachments for Threshing-Machines, of which the following is a full, clear, and exact description.

This invent-ion relates to certain improvements in feeding attachments for threshingmachines and the like, and has for its object to provide a device of this character of a simple and inexpensive construction having means for cutting the bundles and feeding the grain to the separator, the construction being such that the device is increased in capacity and better results than heretofore attained.

The invention contemplates certain novel features of the construction, combinatiomand arrangement of the various parts of the device, whereby certain important advantages are secured, and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use than prior devices of the class to which it relates, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicafe corresponding parts in all the figures.

Figure 1 is a side view showing the device in position for use. Fig. 2 is a vertical section taken longitudinally through the device. Fig. 2 is a perspective view showing the pivoted plate which engages the concave and supports the rear end of the conveyer. Fig. 3 is a rear end view of the device. Fig. 3 is an enlarged fragmentary view showing the means employed for taking up looseness between the sides of the conveyor and casing. Fig. 4 is aview similar to Fig. 1, but showing the opposite side of the attachment. Fig. 5 is a plan view showing the carrier detached. Fig. (3 is a fragmentary sectional view taken vertically through one side of the carrier and showing the adjustable side board thereof, and Figs. 7 and 8 are respectively a fragmentary side view and plan view showing on wheel an enlarged scale the means for actuating the carrier.

In the views, 1 represents the separator to which my improved attachment is applied, 5 5 said attachment being supported by means of inclined supports or braces 2 and comprising a casing 3 of suitable construction, as clearly shown in the drawings.

In the casing 3 is journaled a transverse 6o shaft at, having at one end a pulley 4: to be engaged by a belt 5, passing over a pulley 6 on a shaft 6 of the separator. On the shaft 4, within the casing 3 and extending across the same, is a drum 10, having knives 11 mounted on its periphery to engage and cut the bands.

The rear end of the casing 3 is provided at its lower part with projections or brackets 13 at opposite sides, having vertical guide-rods 7o 14, forming guides wherewith engage the ends 15 of a shaft 19, extending transversely across the carrier, between the side rails or sills 16 thereof. At its forward end the sides 16 of the carrier are provided with upturned bracle 7 5 ets or side pieces 17, and at opposite ends of the bottom 18 of the carrier are journaled the shafts 19 and 20, over which passes the endless carrier 21, which may be of any construction, being preferably formed of an endless 8o flexible apron having transverse strips secured on its face, as seen in Fig. 5.

On the shaft 19 is mounted a sprocket- 22, over which passes a chain or link belt 23, geared to a sprocket-wheel 24 on a short shaft 25, journaled on one side of the casing 3, and on said shaft is mounted a second sprocket-wheel, 26, geared by a chain or link belt 26 to a sprocket-wheel 27 on a crank-shaft 28, journaled below the casing 3 go at the rear part thereof and extending transversely across the said casin g to the opposite side thereof, 'where it is provided with a pulley 29, over which extends a belt 30, passing around a pulley 31 on the adjacent end of the 9 5 drum-shaft 4:. In this way the crank-shaft 28,

the cranks of which actuate the conveyor, and the shaft 19, which actuates the carrier, are driven from the drum-shaft 4, and in order that said parts may be conveniently 10o thrown into and out of operation I provide a belt-tightener 7, having a roller 8 normally pressed by a weighted arm 9 against belt 30,- so as to hold the same tight. When said belt tightener is thrown out of operation, the con veyer and carrier are stopped.

The sprocket-wheel 22 is loose on the shaft 19, being capable of both rotative and longitudinal movement thereon, and said wheel is integrally formed or secured to a clutch member 32, arranged, when slid along said to shaft, to engage a similar clutch member 32,

forks on the end of a lever 35, pivoted or hung loosely at 36 on the carrier-frame and arranged to be engaged on its inner side or that side next said carrier-frame by a wedge 37, carried on a lever 38, fulcrumed at 39 on the said frame and connected at its ends with shifting ropes or the like 4.0 and 41, extending along the side of the carrier in position to be conveniently manipulated by an attendant to move the wedge into and out of engagement with the said lover or rod 35, so as 40 the separator.

to engage or disengage the clutch members and stop and start the carrier, as will be readily understood.

Cords 42 or equivalent flexible connections are secured to the forward end of the carriel frame at the ends of the shaft 19, and said cords pass over sheaves or rollers 43 at opposite sides of the top of the casing 3, and are carried forward to a suitable connection with By drawing on said cords the carrier may be raised and lowered to any desired position, so that the carrier may be loaded to the top of the feeder for convenience in moving.

The carrier-frame is provided along its opposite sides with adjustable side boards 45, held in inclined positions by means of triangular braces or brackets 46, secured to their outer sides, as clearly seen in Fig. 6, the lower horizontalmembers 47 of said braces being arranged to slide through apertures 48 in the side bars 16 of the carrier-frame, so that said side boards may be conveniently adjusted in or out to give the carrier more or less width.

In the interior of the casing 3 a shelf 49, forming above it a transverse guideway 50, extending across the upper part of the casing and adapted to receive a sliding plate 51, to which are secured two or more spring- 6:; plates 52, the ends of which are bent down and provided with knives 53, held over the drum 10 in position to cut the material passin g over the same into the separator, and said casing is provided behind said knives with a downwardly-inclined deflecting-wall 54, arranged to deflect said material and deliver the same to pickers 56, mounted on a shaft is arran ged 57, extending transversely across the casin g and provided outside the same with a gear 58, meshing with a pinion 59 on the shaft 25, whereby said pickers are driven.

60 represents a conveyor located in the lower part of the casing 3 below the drum 10 and comprising a board provided with transverse serraii )ns 61 in its upper face, said serrations having their forward walls made vertical and their bottoms sloped up rearward, so that the shatterings falling thereon will be held against being discharged from the open end of the casing and will be conveyed into the separator.

To opposite sides of the conveyer 60 are secured spring-metal'plates 63, the upper edges of which are secured to strips 64, of wood or the like, extending along the inner sides of the casing These springs serve to take up all loosen ess l: etween the sides of the conveyer and casing, so as to prevent the loose grain from falling outside the open bottom of the casing.

The rear end of the conveyer is held on cranks 65 on the crank-shaft 28, said cranks engaging boxes 66 on the under side of said conveyor, whereby arocking or shaking movement is imparted to the rear end thereof, while the forward end of the conveyer is supported on a bar 67, resting on a tilting or swinging plate 68, (seen in detail in Fig. 2%) having its free edge arranged to engage the concave 69 of the separator. Said plate 68is provided at its rear edge with depending flanges 7 0, having outwardly-directed lugs 71 to engage perforations in the lower end of straps '72 on opposite sides of the casing. In this way the conveyer is always held in position to deliver to the separator, while the concave may be adjusted at will.

At its forward end the conveyer is provided with upwardly and rearwardly extending projections or arms 73, whereon is supported an inclined floor 74 similar to the floor or bottom 60 of the conveyer proper and' having its upper end arranged to receive the grain passing over drum 10 and its upper face formed with strips or serrations similar to the serrations 61 in the bottom 60. Plates 75 are also secured on the floor 74, as clearly seen in the drawings, and said plates serve to carry forward the straw to the separator-cylinder. A series of cleaners 55 are mounted on a support- 55 below the rear upper edge of the floor 74, and serve to clean the straw from the knives 11 on drum l0.

In operation the carrier is arranged at a proper elevation to feed the material into the a casing, and is adapted to be operated by four men, two on either side. The sheaves when thrown on the carrier will be straightened out automatically in case they strike with one end on the inclined side pieces 45, so that little care is required in feeding the sheaves to the carrier.

The sheaves are delivered to the drum 10, over which they pass, being cut by the knives I DO IIO

ll thereon and also by the knives on the spring-plates 52, and the cut material is fed to the pickers 56 and thence to the separator. Should any straw adhere to the knives on the drum 10, it will be removed by the cleaningplates 62, and said plates, together with the serrations 61, serve to hold the loose grain against falling out of the casing and discharge the same through the opening 76 below the floor 7st to the separator.

The device constructed as above described is extremely simple and inexpensive and is well adapted for the purpose for which it is intended, since it effectually prevents the loss of the shatterings and is notliable to get out of order.

It will also be obvious from the above description of my invention that the device is susceptible of considerable modification without material departure from the principles and spirit of my invention, and for this reason I do not wish to be understood as limiting myself to the precise form of the parts herein set forth.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
