Manufactured by Pitts Agricultural Works - Buffalo, Erie County NY
Assigned to Pitts Agricultural Works - Buffalo, Erie County NY

Abstract: The objects of the invention are, first, to provide a rake of this character composed of a minimum number of parts; second, to dispense with a separate tooth-guide independent of the rake-head; third, to provide a combined hand and foot retaining-lever; fourth, to form an improved yielding flexible connection between the retaining-lever and the rake-head; fifth, to mount the rake-head directly above and in line with the clearer-head, so that any strain upon one will be exerted upon the other and the full strength of the clearer-head is utilized in supporting the rake-head; sixth, to simplify the construction of the draft-frame; seventh, to form improved connections between parts united by threaded bolts, whereby in some instances nuts on said bolts are rendered unnecessary and in other instances the bolts are held out of contact with the holes through which they project and parts are held as against moving out of position; eighth, to form improved means for disengaging the pawls of the trip-shaft from the ratchet of the carrying-wheels; ninth, to provide improved means for normally holding the connection between the retaining-lever and the rake-head out of a dead-center; tenth, to provide an improved trip-lever and means for connecting the same and limiting the movement thereof; eleventh, to enable the rake-head to be securely held when elevated, so as to prevent any downward movement thereof, and hence avoiding contact of the pawls with the ratchets while the rake is elevated; twelfth, to provide improved clips for attaching the rake-teeth to their head, and, thirteenth, to provide a draft- equalizer whereby the swinging of the rake from side to side is reduced to a minimum. Claim: In a horse hay-rake, the combination with the draft-frame and the carrying-wheels having short axles, of the clearer-head supported at its ends by said axles, the hinging-arms connected to said clearer-head having extensions provided with openings and recessed sides, the draft-frame having corresponding bars fitted in said recessed sides, the eyebolts binding said bars to said extension, the shafts connected by said eyebolts to said draft-frame, and the rake-head pivotally supported by said hinging-arms.

Abstract: The first part of my invention relates to the circular frame resting upon the axles of the deriving and steering wheels or upon intermediate frame supporting the machinery used for forming the propelling power. The second part of my invention 'relates to the fore part of the afterbody of the carriage, which rests upon and is extended in cylindrical or circular form or framework around the aforesaid circular frame of the fore-body, which rests upon the axles of the driving-wheels or upon an intermediate frame. This arrangement affords a support for the forebody of the vehicle; it also allows the said forebody to turn independently, the object being to enable the carriage to be steered in any direction by the regulation of the speed given to either of the (hiving-wheels. The third part of my invention relates to the inner hub attached-to the driving-axles and its projecting arm, which, when "in motion, becomes connected with a projection from the driving-wheels, the object of which is to prevent the engine being caught ,on a center when the power is being applied to the aforesaid driving-wheels. Claim: The circular frame of the forebody B B resting upon the axles K K of the driving-wheels C C.
