. Application inea october so, 1919@ serial naaafiea y To all 'whom t may concern.'

Be it known that I, BERNARD M. McFAn- LANE, a citizen of the United States, residing at Hettinger, in the county of Adams, State of North Dakota, have invented certain new and useful Improvements in Binder Ele* vators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Vwill enable others l0 skilled in the art to which it appertains to make and use the same.

rilhis invention relates to grain binders, and more especially to that class of devices known as endless belt loaders; and the obf' jectof the same is to produce a simple forni of elevator mechanism which can be applied to the binder by first removing certain parts of the latter, and isserviceable for carrying grain from the table of the binder to the header box. p

The invention includes an elevator consisting of an ordinary endless canvas belt or apron with slats, but it has specially constructed sides andftop for holding the grain in place on the upper stretch of the apron,

yielding when necessary, and preventing the .action of wind thereon, and it has means whereby the upper end of the entire elevator may be raised or lowered or held at any desired height.

t is my purpose to produce a cheap and serviceable article of this character which can be sold to the farmer and by him ap-y plied to a standard make of binding inachine.

The following specification sets forth one successful embodiment of the idea, reference being had tothe drawings in which:

Figure l is a perspective View of this device complete, indicating `in dotted linen a power chain applied to its driving sprocket and a rope attached to its bail. v

Figure 2 is a cross section on the line 2 2 of Figure l.

Figure 3 is a longitudinal section.

The frame 0f this elevator includes rather wide upright sides l connected by a bottom board 2 at their lower ends and by a wider bottom board 3 at their upper ends, and the upper edges of the side boards are preferably also connected by straps 4t at their upper and lower ends. A roller 5 has truniiions 6 journaled in bearingsifat the lower ends of the sides, and fonefof .said truunions has ay sprocket wheel I to which a power lchain may be applied asseen in dotted lines. similar roller has'its Atiunnions 8 yournaled inthe side boards near their lupper ends."` `lrround these rollers .nioves an endless canvas'belt or apron Qhaving slats l() secured acrossits outer face at inter vals, and the chain and sprocket will vcause the upper stretch of this apron tomove upward between the si'des,'which latter will prevent a lateral blast of windv from striking the grain which lies on the elevator.

Supported1 `at 20 in theside boardsvfnear their lower ends is a rockable cross bai"21 carrying a seriesof vretainerbars 22"extend= ing longitudinally within theJ `frame and standing parallel vwith and .rather close vto each other, and the uppery ends of these ref` i i tainerbars are supportedy by a notched bar or combl 23 whose back 24 extends across between the side boards near their upper ends and whose teeth which are flattened at their lower ends, are spaced to correspond with the spacing of the retainer bars and have the upper ends of said retainer bars attached thereto, leaving the spaces between the teeth alining with the spaces between the retainer bars'. At each endof the comb is attached a flexible element such as a strap 25 which leads over the upper edge of a side board and is secured to the outer side of the same as at 26. These straps prevent the comb from falling to such a distance as to permit the upper ends of the slats to stand undesirably close to the cross slats on the apron, while at the same time the straps permit thev comb and the upper ends of tached, as shown in dotted lines in Figure The upper edges of` l, the same serving as vmeans for adjusting the upper end of the elevator to any desired position and holding it there.

In applying this device to an ordinary binding machine, the binding parts of the latter are removed and theelevatorattached,

its sprocket being connected with the saine chain that drives the lower elevator on said machine.v The upper end of the elevator is now adjusted so as to lead 'to the header box. The grain cut by the machine is delivered to the lower end of the elevator and onto its apron or belt beneath the retainer'bars 22, and the apron carries or elevates the grain and ldelivers it to said box. In its passage upward on the upper stretch of the apron,

it is held thereon by the retainer bars' andv moves beneath them, and any pieces of grain which project between the retainer bars will move through the spaces between the comb teeth. The weight of the comb added to that of the upper ends of the retainer bars holds the latter down' onto the grain and the grain down on'the apron, but the flexible lconnection or straps 25 permit the comb and retainer bars to rise incase the'accumu lation of grain is sufficient, andthus thev choking or cloggrgiiigg of the elevator at its outlet end is prevented. The opening'at the bottombetweenthe bottom boards 2 and 3 permits the dropping out of whatever is carried over the upper roller by the apron, and thus the choking and clogging oi" the lower stretch ofI the elevator is prevented. While my invention is primarily intended` for aiise such as has'been described7 l do notv wish to be limited to that particular use.

Also, while have describedI and shown a canvas apron with cross slats, l claim no novelty for this detail.

What is claimed is:

A binder elevator including` a frame, an endless belt mounted in the frame, a'transverse bar rotatably mounted in the sides of the lower portion of the frame for rocking movement, a transverse bar extending between the sides of the upper end of the frame, flexible straps secured to the ends of the last-named bar and to the sides oi? the frame to perinitthe bar to rise and fall under the influence of material passing thereunder and to maintain said bar in spaced relation with respect to and above said belt, the lower portion of the upper bar being formed with a longitudinal series of depending; teeth each having its lower end lattened, and retainer bars extending longitudinally of the frame and over the endless belt with their upper ends secured to the said flattened ends of' the teeth of the upper bar and their lower ends secured to the lower 'face oi the rocking,l bar 'for rocking movenient therewith.

In testimony whereof, I affix niy signature,'in the presence of two witnesses.
