IMPROVEMENT IN RAKING ATTACHMENTS TO HARVESTERS.

Specification forming part of Letters Patent No. 20,475. dated June 8, 1858.

To all whom it may concern:

Be it known that 1, JOHN A. BARRINGTON, of Fredericktown, in the county of Knox and State of Ohio, have invented a new and useful Improvement in Harvesters; and I do hereby declare that the following is "a full, clear, and exact description of the same, reference being had to the annexed drawings, forming part of this specification, in the several figures of which similar characters of reference denote the same part.

Figure l is a top view of platform and raking mechanism. Fig. 2 is a vertical section on w at. Fig. 3 is a vertical section on y y. Fig. 4 is a section through axis of vertical shaft, showing manner of connecting crane therewith. Fig. 5 is a cross-section of crane on 22.

The nature of my invention consists in a peculiar combination of devices, hereinafter to be described, for grasping the gavel, conveying it to the rear of the machine, and discharging it perpendicular to the track of the machine, the details of construction and operation being as tollows.

The grasping mechanism consists of two rakes. f f, each suspended by a pin, a, from a slide'piece, b, movable longitudinally in the arm of a crane by a cord-connection, c, with a pulley, d, at one extremity, the cord passing around another pulley, c, in the end of the crane-arm. The rakes ff are moved upon their suspending-pins by the groove 9. in which a stud, 'v, on the rake-arm moves, as will be set forth.

The crane-arm A is designed to move rearward ninety degrees, deposit the gavel, and

then return to the position shown in the drawings. The arm has two branches, It h, embracing the vertical shaft B, and is connected with the shaft when the lever-catch i has the position shown in Fig. 4. Upon the shaft B and above the branch h of the crane-arm is a cog-wheel, O, by which motion is given to shaft B from a reciprocating rack-piece, R. Near the head of the shaft B isfa wheel, W, partly toothed, meshing with pinion k on the shaft of pulley d, and giving motion to the slidepieces to which the rakes ff are attached. The rack It is reciprocated by the alternate meshing of a wheel, D, on the main axle E, with the racks r r in the said slide-piece. The piece R being brought in connection with these racks by reason of the studs m m on piece R following the groove Z Z in the fixed plate G. The branch h of the crane has two notchesmt, for the reception of catch 1', which said notches are distant from each other ninety degrees. The crane will therefore turn with the shaft B during the time catch 1' is in one of the notches m, and the shaft will move independent of the crane during the time the catch is out of the notches, which is three-fourths of the revolution. The rack-piece R is held in position against plate G by the guides k It, so as to reciprocate freely behind them. It is lifted so as to place p ns 112 in upper groove, Z, by cams p p, operated by lever g. This same lever, by drawing upon rod t, turns shaft s and moves catch it so as to release theorane. The wheel D has a ratchet-connection with its axle, so that the backing of the machine has no effect upon the mechanism operating the crane and its rakes.

The operation of the several parts is as follows, commencing with the position shown in the drawings: The rakes are extended to grasp the grain. The stud n in the handle is entering inclined portion 1 of groove g, spring w on slide b having lifted the rake-head into this portion of the groove. Pins m m are in the lower grooves, l, of plate G, and the rack r is meshing with wheel D. The slide-pieceR moves to the front and rotates shaft B, and causes the slides b of the crane to be drawn together. The stud o ofrakef follows groove 9 and enters straight portion 2 thereof, and is drawn along said portion. The same being the condition of rake f, the two rakes are close together with the gavel between them and the bearing-piece N. At this time catch 't' falls into one of the notches m, and the crane is turned to the rear ninety degrees, when one of the teeth of the side rack of piece R presses upon pin a, removes catch 6 from the notch m, and severs the connection between shaft B and the crane. Previous to the commencemerit-of this crane movement the extremity of slide-piece b strikes lever c and lifts catch 61, which holds the said crane. The rack-piece It has by this time run to its front limit, the wheel 1) being under the plane portion e. Spring-brace i has passed under guide 70 and abuts against the front edge thereof. Lever q is then moved, causing arms 19 p to lift piece it, so as to bring studs m m into groove 1. and

effect the meshing of wheel D with rack 'r. a

The spring-brace-has a curved extremity,which,- acting against the guide k, throws rack-piece R a little forward and insures the clearing of partition 1" by studs m when power is applied to raise piece R. Brace 'i passes through groove 5, when rack-piece It is elevated and the opposite movement begins. The slides b in the crane are now drawn in the opposite direction. The rake-handle presses against a spring-stud, 0, while stud '0 is drawn into portion 3 of groove 9. This causes rakes f f to separate, which separation continues as stud 1) passes into and along portion 4 of groove g. This deposits the gavel and takes up threefourths of the revolution of shaft B, at which time catch '6 enters the other notch m, and crane A swings into the position of the drawings, ready to take up another gavel. Studs on m then drop into groove L, and the operation is repeated, as above described.

Having described my invention and the op eration thereof, 1 claim- 1. The reciprocating and vertically-moving rack-piece R, operating substantially as de- J. A. BARRINGTON.
