DANIEL IV. SMITH, OF CHICAGO, ILLINOIS, ASSIGNOI-t TO INTERNATIONAL HARVESTER COMPANY, A CORPORATION OF NEW JERSEY.

Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed March 3, 1905. Serial No. 248,259.

To alt whom it may concern.-

Be it known that I, DANIEL W. SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and @tate of Illinois, have invented certain new and useful Improvements in Sheaf-Uarrier Attachments, of which the following is a specification, reference being had to the accompai'iying drawings, forming a part thereof.

My invention relates to sheaf-carrier attachments for grain-harvesters; and it is particularly designed for use in connection with attachments of the above character having endless-apron carriers operative to deliver the sheaves therefrom, the object of the invention being to provide means for retaining the sheaves upon the carrier and preventing their premature delivery therefrom until by the regular operation of the carrier they are de posited upon the ground.

My invention consists in providing an endgate that is pivoted on the frame of the carrier and operates to close the delivery end thereof whileit is receiving its load and which is released and allowed to swing outward as soon as the endless carrier begins its movement to discharge the accumulated load.

Figure 1 represents a plan view of a harvesting-machine having a sheaf-carrier embodying my invention attached thereto. Fig. 2 represents a plan view of the carrier detached from the machine. Figs. 3, 4:, 5, and (3 are views showing details of construction, and Figs. 7 and 8 represent details of the clutch mechanism.

The same reference-numerals denote like parts.

7 represents the main frame of the harvester, upon which the grain-receiving platform and cutting apparatus are mounted.

2:: represents the push-pole, and 9 the platform upon which the operator stands.

10 represents the binder attachment, located at the delivery end of the carriers and adapted to deliver the bound sheaves stubbleward therefrom.

11 represents a sheaf-carrier frame, suitably supported at the delivery side of the binder attachment, and 12 represents an endless car rier mounted upon suitable driving and driven rollers that are journaled in said carrierframe.

The endless carrier is given motion through its connection with a moving part of the harmovement of the lever 15-connects the driving-roller of the carrier with the continuously-driven member in any of the well-known ways. The carrier is tripped into intermittent movement to discharge the load by the operator pressing with his foot upon the triplever 16, mounted upon the platform 9. The trip-lever is connected, by means of a link 17, with a bell-crank lever 18, mounted upon the harvester-frame an d connected with the cl utchshipping lever 15 by means of the link 19.

Pivoted upon the outer front corner of the sheaf-carrier frame is an end-gate 9.0, which is normally held closed across the delivery end of the carrier by means of a spring 21 coiled about its pivot and arranged to operate to close said gate. A short crank-arm 22 forms part of the end-gate connections, and 23 is a link pivotally connected to said crank and extending along the front of the carrier-frame is supported near its opposite end in a yielding manner by means of the spring-loop 24. A hook portion 25 is formed on the link that is adapted to engage with a fixed part of the carrier-frame, as shown in Fig. 6, in a manner to hold the said end-gate closed. The link 23 is extended inward beyond its hooked portion, and 25 is a rockshaft suitably supported by the side bars of the carrier-frame, having the crank portion 26 adapted to engage with the link 23 in a manner to cause its hooked portion to be disengaged from the fixed part when said rockshaft is turned in one direction, as shown in Fig. 4. At its opposite end said rock-shaft 25 is provided with a crank portion adapted to engage with the clutch-shipper lever 15 and be moved thereby to rock said shaft in its bearings and cause it to release the endgate.

The end-gate is caused to open by the pressure of the load of bundles during the discharge operation of the carrier, and it is im mediately closed by the action of the spring mechanism when the discharge of the load is effected. The tripping mechanism is caused to return to its initial position by means of a spring under the foot-lever 16.

The clutch mechanism comprises the continuously-rotating sprocket-wheel 13, having a clutch-tooth 28 on its inner surface that is adapted to engage with a roller 29, mounted on one end of a vibratilelever 30, that is pivotally mounted near its middle portion upon a part 31, secured to the shaft 32, that is connected with the driving-roller of the carrier. A coiled spring 33, operative between the opposite end of lever 30 and the part 31, normally holds the roller 29 from contacting with the tooth 28. Upon the endof shaft 32 is a longitudinally-movable sleeve 3st, having a slot 35, through which projects a pin 36, that allows the sleeve to have a limited longitudinal movement on the shaft. The lever 15 has one arm bearing against the sleeve, and 37 is a coiled spring operative between the end of the shaft and the sleeve in a manner to press the sleeve against the lever. At the opposite end of the sleeve is a projecting arm 38, having an inclined portion 39 adapted to engage with the lever 30 in a manner to force it inward, and thereby cause the roller 29 to come within the path of the tooth 28, and thus clutch with the continuously-driven sprocketwheel in a well-known way.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a sheaf-carrier, the combination of a carrier-frame, an end-gate mounted to turn about a vertical pivot at the front and stubbleward corner of said frame, means for closing said gate across the delivery end of said carrier, means for locking said gate in its closed position, and means for releasing said locking means.

2. In a sheaf-carrier, the combination of a carrier-frame, an end-gate mounted to turn about a vertical pivot at the front and stubbleward corner of said frame, a spring operative to close said gate across the delivery end of said carrier, means for locking said gate in its closed position, and means for releasing said locking means.

3. In a sheaf-carrier, the combination of a carrier -frame, an endless carrier mounted upon said frame, means for intermittently operating said carrier, an end-gate mounted to turn about a vertical pivot at the front and stubbleward corner of said frame and means for normally looking it in a closed position across the delivery end of said carrier, and means connected with said intermittentlyoperating means for releasing said locking means.

4:.
