My invention relates to new and usefulimprovementsin swather attachments, an object of my invention being to provide a device of the character herewithindescribed whereby single or double swaths may be laid down-by a single '2 Claims. (01. 198-102 machine instead of using two machines as heretofore.

A further object of my invention in conjunction with the foregoing object is to provide a device of the character herewithin described whereby the operator can select a single swath when the yield of grain is heavy or a double swath when the yield is light thereby enabling an associated combine to work efficiently at all times.

Another objectofmy invention is to provide a device of the character herewith n described whereby the change from single to double swathlaying or vice versa can be made by the operator without stopping the machine.

A yet further object of m invention is vide a device of the character herewithin described which is particularly suitable for attach ments toconventional swathers, and which does not increase the width of said machines to any material extent. H e r a A further object of my invention is to provide a device of the character herewithin described which is relatively light in weight and is easily attached and detached to conventional swathers. A still further object of my invention is to provide a device of the character herewithin described which maybe driven from any convenient source of, drive upon existing swathers..

Yet another object of my invention is to provide a device ofthecharacter herewithin described which is relatively simple inoperation, economical in manufacture, and. otherwise well suited for the purpose forwhich it is designed.

With the foregoing objects in view, and such other objects and advantages as will become apparent to those skilled in the art to whichtthis invention relates as this specification proceeds,

my invention consistsessentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which: v

V V "[Figure 2 is an enlarged'top plan view of my swath-laying conveyor per se. Figures-is a rear and elevation of Figure 2.-

'Figure 4 is a schematic representation of the means provided for selective reversible movement of my swath-laying conveyor but reversed from Figure 3.

Figure 5 is a perspective view of my transfer conveyor per se.

In the drawings. like characters of reference indicate corresponding parts in the difierent figures. In large scale farming, the present practice in harvesting is to use two swathing machines, one being fitted with an extending conveyor in order that the cut grain may be conveyed over onto the swath laid by the first machine travelling in advance, which machine is of standard construction; This entails the use of two operators, two tractors, and two swathers, and the entire field has to be cut in this way resulting in a considerable wastage of man power and effort.

"Furthermore, this provides a double swath under all'conditions which is not desirable inasmuch as whenth'eyield of grain in one particular sectionof the field is extremely heavy, the combine dealing with this grain is slowed down considerably. However, it is a decided advantage to maintain a double swath where the yield 'is light so that the combine is provided with sufiicient grain for efiicient operation.

Therefore, I have designed the swather attachment hereinafter to be described which permits single or double swath laying to be undertaken by a single machine at Will thereby enabling the operator'to select the type of swath to be laid depending upon conditions of yield thus evening up the combine in operation which normally follows.

In the accompanying drawings, the conventional portions of the swather have been shown fra'gmentarily, the various drive means to the components having been deleted for clarity. Proceeding now to describe my invention, it will be seen upon reference to the accompanying drawings that I have provided a substantially rectangular framework I mounted upon a shaft' 2 supported by ground-engaging wheels 3 only one 'of which is shown. A conventional reel 4, cutter-bar 5, and main conveyor table 5 are provided and driven from whatever source of power is available tothe particular type of swather upon which my attachment is assembled.

The main conveyor table 6 operates in a direction of arrow I thereby normally depositing out grain in a swath through a discharge area 8 situated at one end of the aforementioned rece tangular framework I.

Within this area 8 I have provided what I define as a transfer conveyor collectively designated 9 which is adapted to run substantially at right angles to the direction of movement of the main conveyor 5, which conveyor deposits out grain upon the transfer conveyor as will hereinafter be described. 7

ers l mounted uponsh'afts H which are journalled for rotation within the rectangular framework I, the rollers being situated substantially adjacent the forward edge l2 an'di the rear edge 13 of the main conveyor 6. A further rolier'l t is mounted upon a shaft l5, which is journal led for rotation to the rear andab'o've"thefiarmember l6 of the aforementioned -rectangular frame I as will hereinafter be described.

The forward portion 19 is substantially paral- "lei "although at right "angles to "the upper run ofltiie aformentioned main conveyor-"5 and does not commence to elevate until clear of therear edge H3 "thereof. flhe 1 rear portion -20 -of the transfer --c'onveyor is guided upwardlyandreartv'ardly by' means of 'angle iron guides 2 l extend- *ifi'gfrom brackets 22 to spindlel5 upon-which the" rear roller is mounted I 'These g'uidesare curved-as illustrated in Figure "fi thus guiding the upper run of the forward end "'o'ftheconveyor 2 0 ina gentle curve towards the "i'olier'll.

One end of shaft l'5'=is extended-and provided wima-pcuey 23 aroundwhich a-belt 24- extends "to a'" convenient "sourceofdriving power -(not'il- -histrated) from the main swath'er.

I have provided means for-=driving-carivas- 32 in either direction thereby permitting this convey'or to be capable of selected reversible movement as required by the operator of the swather. The means to provide this selected reversible movement is shown in detail in Figures 2, 3 and 4 and includes a main drive-shaft 33 supported for rotation within a bracket 34 extending from member 21 and within a bearing contained a"= =plate Biwoolted to member 29 of the rectan- --"gula'r framework 26 of the swath-laying conveyor.

Having described my devicein detail its method of; operation will now be presented.

T The swather is dr-iven by means of a tractor or other similar sources of power in the direction of arrow54, cut grainbeing deposited upon the main conveyor canvasa whicheonveyssame towards-theareamas hereinbefore described. The grain is deposited upon the transfer conveyor which operates in the direction of arrow 55 thus carrying the grain to the rear of the swather and upwardly as shown in Figure depositing same upon the swath-laying conveyor 25. If it is desired to lay the swath to the left of the machine with reference to Figure 1, then lever 48 is moved in the direction of arrow 56 thus causing belt 43 to be tightened by the engagement of pulley 50 with the upper run 5| thereof which causes the upper run of the conveyor canvas to move in the direction of arrow 47. At the same time, hook 52 upon the opposite end of cross-bar 49 lifts the upper run 5| of belt 44 clear of the sheaves thus permitting same to idle.

If it is desired, upon the next round for example, to lay the swath in the same path, then the direction of travel of canvas 32' of the swathlaying conveyor 25 is reversed by moving lever 48 in the direction opposite to arrow 56. This causes pulley 50 to engage the upper run 5| of belt 44 thus tightening same and causing the drive to be transmitted to pulley 4| thus reversing the direction of travel of the canvas. 'At the same time, the hook 52 upon the opposite end of the cross-bar 49 raises the upper run 5| of the belt 43 thus allowing this belt to idle at this time.

In conclusion, while I have described a beltdriven system for reversing the direction of travel of canvas 32' of the swath-laying conveyor, it will be appreciated that, if desired, a system of drive-shaft and bevel gears, together with a reversing gear-box could be utilized but, for simplicity, the present embodiment is preferred.

Since many modifications can be made in the invention herein described and since the accompanying drawings have been prepared only to illustrate the relative arrangement and interaction of parts and not with regard to accuracy of dimensions for manufacturing purposes which in view of this disclosure I consider to entail merely mechanical skill together with the skill of the mechanical draftsman, and since many apparently widely different embodiments of this invention may be made within the spirit and scope of the accompanying claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense and I desire only such limitations placed thereon as justice dictates.

What I claim as my invention is:

1. A conveyor attachment for swathers and the like, said swather including a conventional main conveyor platform or table and transfer conveyor at right angles thereto, said transfer conveyor including a pair of rollers, an endless canvas rotatable thereon, means for driving one of said rollers, the forward portion of said transfer conveyor spanning one end of said main conveyor table, the rear portion of said transfer conveyor curving upwardly and rearwardly from the rear edge of said main conveyor table, a swathlaying conveyor at the rear of said swather substantially parallel to said main conveyor table, the rear end of said transfer conveyor being mounted upon the supporting structure of said swath-laying conveyor and overlying said swathlaying conveyor thereby permitting cut grain to be transferred from said main conveyor table and deposited upon said swath-laying conveyor, said swath-laying conveyor including a pair of supporting members extending rearwardly from the main frame of said swathing assembly, a substantially rectangular framework supported by said members, a pair of rollers mounted for rotation within said framework, an endless canvas extending around said rollers, means for driving one of said rollers, said swath-laying conveyor being capable of selective reversible movement, and means to provide said selective reversible movement.
