T0 at whom-it may concern:

Be it known that we, WILLIAM A. GAR- Lrrs and THOMAS WOODARD, residing at Cald- Well, in the county of Sumner and State of Kansas, have invented a new and Improved Adjustable Straw-Rack, of which the following is a specification. 7

Our invention, which relates generally to grain-separating machines, more-particularly has for its object to provide an improved construction of adjustable straw-rack for separators of a simple and economical conarts are cooperatively so connected an combined whereby they can be quickly and positively adjusted to provide forthe desired setting of the rack-slats for permitting the desired and unbroken air-current to pass therethrough to uniformly blow upon the grain-screeners.

Our invention consists in the peculiar construction and novel combination of parts, all of which will be hereinafter described in detail, specifically pointed out in the appended claims, and illustrated in the accompanying drawings, in which Figure 1 is an inverted perspective view of a double-secti0n adjustable rack and showing the preferred form of our invention. Fig. 2 is a similar view of a single rack-section and showing a modified form of our invention. Fig. 3 is a detail vertical longitudinal section of the preferred form, taken substantially on the line 3 3 on Fig. 1. Fig. 4 is a crosssection of the same on the line 4 4 on Fig. 3. Fig. 5 is a detail side elevation that shows the preferred means for clamping the slatholding brackets to the shifterbar, the slats being shown in section. Fig. 6 is a detail view of one of the modified constructions of brackets. Fig. 7 is a cross-section on the line 7 7 of Fig. 4. Fig. 8 is a detail perspective view of one of the slats. Fig. 9 is a detail sectional view on the line 9 9 of Fig. 5.

Referring now to the details of construction, 1 1 designate a pair of shaker-sections, each of which, as shown, includes three longitudinal notched or fish-back members 10 10, the number of said fish-backs in practice depending on the Width of the machine of which our adjustable straw-racks may form a part.

The shaker 'or rack sections 1 each includes a series of overlapping slats 2 2, whose outer ends have short journals 20 20, that engage the bearing-apertures 11 in the lower has a series of such seats 24, one for each of edge of the outermost ones of the fish-back orside members.

The several slats have such correlative ar rangement and adjustment that when closed to their limit they lie flatwise' and overla each other, and thereby ractically close 0 air-draft through them, ut when adjusted as desired said slats, while forming a substantial shaking or separating base, can be set to provide for a uniform and maximum flow of the airtherethrough to the screens above it.

In the preferred construction of our invention all the slats are connected to a means for adjusting all the slats uniformly and in unison, which is best shown in Figs. 1 and 4 and which consists of a longitudinally-disposed shifting bar 3, located under the slats midway thereof and having upon the under side a series of notches or seats 30, one for each slat, each of which receives the crossbearing 40 of a U-shaped bracket 4, one for each slat, and each of which has lateral flanges 41 41, screwed or otherwise made fast to the slat, as clearly shown in Fig. 4, by reference to which it will also be seen the slat midway its length has a reduced or journal portion 23 that engages the bearing-seat 24 in the under side of the central fish-back member, which the journal portions 23 of the slats, to which seats the central bearings of the slats are firmly held by the capstrip 5, that passes over all' the journals 23, and is bolted or otherwise made fast to the under side of the central fish-back member, as shown.

At one end the notched bars 3 have U- shaped notches 33, that form the opposites for similar notches 50 in the locking bars or members 5, which are bolted or otherwise made fast to the shaker-bars 3 and serve to' close over the cross-bearings 40 of the brackets 4 and hold the said bearings securely journaled in their respective notches 30.

6O designate the squared ends of the [00 securing-bolts 6, that fasten the crank end 61 of a rocking-lever 62, journaled on the under side of the cross member 80, that forms a art of the shaker-frame, and the said bolt ends 60 fit within the squared sockets formed to 5 in the outer ends of the shifting and clamping bars.

The rocking levers 62 each have a second crank 63, that join with an adjusting-bar 64,

one end of'which is pivotally connected to a I10 setting-lever 65, that has a latch for engaging a segmental rack 66, which holds the actuating devices and the slats to their adjusted positions.

In Figs. 2 and 5 is shown a slightly-modified arrangement of our invention, and in this form instead of using U-shaped brackets for connecting the slats to the shifting bar we employ angle-shaped brackets 80, having lateral lugs 81, that take through apertures 83 in a single shifting bar 84, and which are made fast to the said bar by turning down the outer ends of the lugs 81, as shown in Fig. 5.

From the foregoing, taken in connection With the accompanying drawings, the advantages and complete structure of our invention will be readily understood.

It is apparent that to increase or decrease the air-passages between the slats the operator need only set the hand-lever on the segmental rack to the desired distance, which effects the adjustment of all the slats in both the sections 1.

By joining the slats to the shifting bar as shown and described an economical and easily-applied connecting means is provided, and when using the single clamp-bar all the brackets can be held secured to the shifting bar under the single operation of fitting the said clamp-bar in place- Having thus described my invention, what I claim, and desire to secure by Letters Patent, is I 1. As an improvement in straw-racks for separators, the combination With the main supporting-frame of a series of fish-back sections mounted thereon, comprising two outer and a central member, the central member having a series of seats in its lower edge, a

series of cross-slats rockably mounted on the several fish-back members to lap 'each other, the ends of the slats having short journals for engaging apertured bearings in the end fishback members, and reduced centrally whereby to form journals for engaging the seats of the central fish-back member, means for holding the said central slat-journals in the said seats, U-shaped brackets that straddle the central fish-back member and have their ends secured to the slats at opposite sides of the central journal thereof, a bar connecting all of the U-sha ed brackets and a means for shifting and ho ding the said bar, the brackets and the slats to their adjusted position, as

set forth.

2. The hereinbefore-describedimproved straw-rack for separators, which comprises in combination, a supporting-frame, a series of fish-back sections mounted thereon, a series of cross-slats for each set of fish-back sections, rockably mounted in the fish-back frames to lap upon each other, a shifting lever for each set of slats in each fish-back section, an adjusting-bar, crank-levers connecting said bar and the shifting bar, each of said shifting bars having sockets, a U-shaped bracket secured to each slat and having it's cross portion fitted in the shifting bar sockets, and a cap-strip detachably fitted over the socketed edge of the shifting bar, as set forth.
