GRAIN-CARRIER.

SPECIFICATION forming part of Letters Patent No. 604,822, dated May 31, 1898.

Application filed April 1, 1897. Serial No. 630,297. (ll'o model.)

To aZZ whom it may concern.-

. Be it known that I, ALVA E. DEWEESE, of Quincy, in the county of Logan and State of Ohio, have invented certain new and useful Improvements in Grain-Carriers; and Ihereby declare that the following is a full, clear, and exact description thereof, reference being had to theaccompanying drawings,which form part of this specification.

v This invention is an improvement in strawcarriers for self bindingor bundling mowingmachines and is also applicable to othermachines or for other purposes. Its object is to provide an endless carrier with bars or rakes, which will move the straw, (360., along to the point of discharge, at which point the forks or bars are shifted automatically, so as to clear themselves of- .the straw and not catch or drag any of it backward, thus preventing clogging of the machine- I am aware that there have been various forms of carriers dethe partsof the carrier proper being shown disproportionately .large for the purpose of clearness of illustration. Fig. 2 is a longitudinal Vertical section on line 2 2, Fig. 1.

Figs. .3 and 4 are detail perspectives of one of the toothed rakes of the upper section and its hinge connection with the sprocket-chain. Fig. 5 is a detail perspective of one of the angle-bar rakes of the lower section. Figs. 6

' and 7 are enlarged diagrams showing how the rakes are withdrawn from the straw at the "discharge end. Fig. 8 isa detail top view of a rake tilted.

Referring to said drawings, A designates the platform or lower section of the conveyor of a self-binding mowing-machine, for examposed of side sprocket-chains D and trans chains D or journaled directly in such links,

so that the rake-bars will be drawn along the lower section, as in ordinary carrier construction. The end of stud e is bent upward at rightangles perpendicular to part E, forming a trip-finger e for the purpose hereinafter explained.

The chains D-run over sprockets F, mounted on shaft F at each end of the section A.

To the floor a at the inner end of the platform is attached a sheet-metal plate G, which is bent down close to shaft F, as shown, and fastened to the under side of the platform, and at proper points adjoining said sheet and above shaft F pins e are secured to the side board of the section in position to be struck by the fingers e on the rake-bars E just as these bars come directly over the shaft the rake-bars are thereby tilted backward, so'that the parts E slip from behind the straw, as indicated in the drawings, and let it drop freely onto the endless'conveyer of section B, as indicated in the drawings. It

will be observed that thepart E of the rake-- has an endless carrier consisting of sprocket chains H, running over sprocket-wheels h on Then as the bars turn down to pass around the shaft-fingers e strike pins 6 and.

shafts h at each end of the carrier, and a at below the shaft, as shown.

bent short down under shaft h and its lower edge made fast to the bottom of the platform To the lower end of the platform I) is attached the edge of a sheet-metal plate 2', which is curved around on a radius equal to the circumference of the sprockets h on the lower'shaft h, and its other edge is bent upward and fastened to a bar I) on the bottom of the platform, as shown, slightly in advance of or above the lower shaft h.

The rakes J of the upper conveyer are of peculiar construction and are made in sections, as shown, two being employed, the inner ends of the sections being pivoted to an intermediate sprocket-chain H, running over sprockets h on shafts h like the chains H.

Each section J of the upper conveyer=rakes consists of a metal bar having at its outer end a narrow forward projection or shoulder J from which projects outwardly, parallel with the section, a pivot-pin j, which is journaled in a suitably-formed link of the chain H or in a journal bracket I1 attached .thereto, as shown. The outer end of pin j is bent up at right angles thereto and perpendicular to the broad face of bar J into a trip-finger j, hereinafter referred to.

The inner end of eachsection J is likewise provided with a shoulder J 3 on its front edge, having a journal-pin j projecting therefrom axially in line with pin j and journaled in a suitably formed link or chain H or in a bracket attached thereto, as shown.

The sections J are provided with a series of short upstanding teeth J at regular intervals apart, which teeth project up through longitudinal slots k in a sheet-metal plate K, overlying the platform b, whilefthe sections J of the bars pass between said plate and the platform, as shown. The ends of plate K are fastened to bars 13 B at the upper and lower ends of section B, so as to be out of the way, as indicated in the drawings, or in other con- Venient manner.

To the side boards of section B, at proper points adjoining upper shaft h, are secured studsj in position to engage fingers j and trip the rakes J backward just as they reach the top of the section. This causes the teeth J 3 of the rakes to withdraw themselves backwardly from the straw, so as to free the latter wholly and let it all drop onto the bundleboards, the withdrawal of teeth J 5 fromthe straw being accomplished similarly to the withdrawal of the rake-bars E therefrom, and

the clearing of the straw being facilitated by the slotted plate K. This plate K may be made of a series of strips, if desired.

By reference to Fig. 7 it will be seen that the teeth J drop backwardout of the straw,

. keeping close to plate I and passing down under the under side of the platform I) in a partly-turned position difierent from that they would have if the bars were fixed on the sprocketchains, and yet not turned completely over. In short, the natural rotation of the bars and teeth with the sprocket-chains as they pass over the upper shaft h is arrested and not completed until after they have passedbelow said shaft. As shown, the bars J are not rotated into position to bring their teeth properly uppermost-until they pass under plate 2', which compels them to rotate in their bearings into proper position.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is

1. In an endless conveyer, the combination of the platform, sprocket-wheels at the ends thereof, endless chains arranged to move rake-bars over the platform and return them under the platform; the L-bars having hingestuds e, e, on their ends journaled on the chains substantially as described, said studs having upstanding trip-fingers e on their ends, with a stationary pin at the discharge end of the conveyer adapted to engage the trip-fingers on the rake-bars and cause the bars to partly turn on their hinges as they pass overthe discharge end of the platform and thus withdraw from the straw, and a guard-plate for turning the rake-bars to natu-. ral position at the front or. grainward end of the platform, allsubstantially as and for the purpose described.

2. In an endless conveyer, the combination of the platform the endless carriers running up over the platform and back thereunder,

rake-bars J having upstanding teeth J at their rear edge, and journal-pins j on their front edge at each end, by which they are hinged on said carriers, and also upstanding tripping-fingers j on the ends of pins j; with fixed studs at the discharge end of. the conveyer adapted to engage said trip-fingers and cause the rake-bars to partly turn downward and backward and withdraw from the straw, &c., on the conveyer as they pass over the discharge end thereof and means for throwing said rake-bars into their natural position before they reach the working-point, all substantiallyas and for the purpose described.

3. In an endless conveyer, the combination of the endless side chains H and intermediate endless chain H having links provided with 4.
