GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent N o. 472,143, dated April 5, 1892. Application ledl January 30, 1891. Serial No. 379,744. (No model.)

To all whom t may concern:

Be it known that I, GEORGE SCHUBERT, a citizen of the United States, residing at Walnut,in the countyof Bosque and State of Texas, have invented certain new and useful Improvements in Grain-Binders; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in down-binders or platform-binders, and is especially adapted for the conveyer patented February17,1S91,No. 446,473, invented by me.

This invention has reference more especially to the compressing, discharging, and starting mechanism for grain-binders.

This improvement relates to the construction and operation of the compressor, the discharging-bar, and a starting mechanism for the bindergearing, together with other features specified in the claims, so as to adapt to the above-mentioned conveyer the Wellknown Appleby type of machines-such as is represented, for example, in Letters Patent of the United States granted to George Esterly, No. 262,026, dated Augustl, 1882, and No. 266,254, dated october 17,1882.

By the above-mentioned improvements the needle can be placed above and the tying mechanism below in a narrow space in the platform, so that the grain can be carried by the conveyer direct to and within reach of the `binder arm or needle, thus dispensing with the elevating mechanism and packing mechanism, as is shown in the drawings, in which- Figure 1 is a plan view of a harvester-platform provided with my improvements, the upper plate of the platform being broken away in various parts to show parts below in full lines. Fig. 2 is a front View of the platform and mechanism. Fig. 3 is a longitudinal sectional view on line 1 1, Fig. 1, the post being partly broken away. Parts beyond the section-line are shown in full lines. Fig. 4 is a cross-section on line 2 2, Figs. 1 and 2, looking as indicated by arrow No. 1 in Fig. 1. Fig. 5 is a cross-section on line 3 3 of Fig. 1 with the cross-sill omitted, looking as indicated by arrow No. 2 in Fig. 1, showing parts beyond the section-line in full lines. Fig. 6 is a side view of the diScharger-bar shown in position with parts of the upper plate of the platform shown in section. Fig. 7 is a detail lview of the lever on the discharger provided with its anti-friction rollers. Fig. 8 is a detail View of the starting-lever on the shaft CZ and an enlarged plan View of the dog carried by said lever. Fig. 9 is a plan view of the rod provided with the block or ferrule carried by the compressor and a plan view of the ferrule, and Fig. 10 is a front view of the mechanism with the needle elevated.

A designates the finger-bar of the ordinary Z form. Said finger-bar can be extended with its stubbleward end to the harvester-frame. (Not shown in the drawings.) A

,l A designates an inclined ange extending from near the inner shoe B3 stubbleward a proper distance, for the purpose hereinafter stated. Said flange A can be constructed as a part of the finger-bar A, or constructed in a separate piece provided witharight-angled flange a2, by which it can be secured to the finger-bar A, as shown in Fig. 1.

a. designates the lower` plate of the platform, secured with its front edge to the lower iiange of the linger-bar and with its rear edge to the sill B.

a is the upper plate of the platform, secured with its front edge to the upper flange of the linger-bar A and with its rear'edge to the sill B. Said sill B forms the rear sill of the platform, and is provided with an inclined extension at its stubble end to correspond with the inclined extension A.

The plates a and a extend stubbleward to the ends of the sill B and the flange A', with the plate a curved down at its stubbleward end to partly close the stubble end of the platform, as shown. The front edge of the plate d is turned down to a right angle, (indicated at a3 in Fig. 1,) by which it can be secured to the inclined flange A. On said stubbleward extension of the platform is placed in an upright position the binderframeD a proper distance stubbleward from the shoe B3, as shown, and secured in any suitable manner to the finger-bar and the inclined flange A.

B is a cross-sill extending from the lingerbar A and inclined flange A to the sill B.

IOO

Said cross-sill B is of suitable width to extend from the plate ct to the plate a, and is placed between the shafts C and d and cut out near the center of its length to provide room for the mechanism hereinafter described.

A2 is a slot left in the upper plate a for the operation of the conveyer.

The inger-bar A is provided on its front edge with the usual guards B2 and a shoe B3.

The binder-frainel) is of ordinary construction and is in general use. D is a brace eX- tending from the stubble end ofthe flange A to the upper end of the binder-frame D.

C designates a shaft journaled with its rear end in the sill B and with its forward end in the bracket C. Said bracket C is provided with an arm C2 and is secured to the fingerbar A in any suitable manner. Said shaft C is provided with a bevel-pinion l) adjacent to the rear side of the bracket C and a pinion b loose on shaft C and located in front of the inclined flange A and held in position by the ferrule C3 and clutch b2. Said clutch b2 is op erated by the shaft C and held in position by the spring b3, which is coiled on the shaft C and presses with one end against the clutch b2 and extends with its other or rear end in a perforation in the shaft C, as shown. C'1 is a collar secured on said shaft C adjacentto the front side of the sill B.

e designates a sprocketwheel secured on the shaft C near the center of the slot A2 and d5 is the binder arin or needle secured onthe shaft d4 adjacent to the rear end of the arm D2 and is of ordinary construction. Said needle, the shaft d4, and arm D2 are partly broken away in Fig. l to show parts below in full lines.

t4 designates a disk secured on the rearward-projecting end of the shaft d adjacent the rear end of the arm D3. 3 are two notches formed in the periphery of said disk t". One or more such` notches may be formed in said disk. (Two are shown in the present instance.) 5 is a stud on its front side and near its periphery, as seen in Fig. 3.

t2 is a lever pivotally secured on the shaft d adjacent to the rear side of the disk 4. Said lever t2 is provided with two lugs t1@ and t to receive the pawl 15G.

T is a spring coiled on the pawl and press ing with its upper end against the lug 110 and with its lower end on a shoulder t11 of the pawl t, pressing the said pawl G downward, causing it to engage with the notches t3 of the disk t4.

t is a stud secured in the upper and free end of the lever lf2, projecting rearward and beneath the upper strand of the chain e.

B designates a post extending from the plate a to the plate a and placed on thegrain side ot` the arm D3 with its rear side flush with disk ffl.

t8 is a lever pivoted to the post B6 a proper distance from its lower end, said lever having its lower end curved forward and a dog or rod t9 pivoted thereto. Said rod i projects stubbleward through a perforation in the post B to engage with the stud t5.

t is a stud secured in the upper end of the lever ts, projecting rearward beneath the upper strand of the chain c.

The perforation in. the post B for the rod 9 forms a guide for the stubbleward end ot` the rod t.

l is an opening made inthe platea ashort distance grainward from the post B and on the front side of the slot A2. A part of the metal is cnt loose at both ends. Part IS is curved upward and a part I" is turned down, as shown in Fig. 6.

I is the discharger-bar provided with two prongs l7 on its free or stubbleward end to more readily engage the bound sheaf and with its other end extending grainward and bent near to a right angle to near a vertical position, forming the part I5, with its lower end rounded to receive the lever I2, secured by a key lf.

l is an eye in the lever 12 to receive the discharger-bar, as described. Said lever I2is bifurcated at one end and provided with antifriction rollers 13 and I4 to operate in the track 2 and projecting with its other end rearward above the lower strand of the chain e. The discharger rests with its rear or grain end on the plate a and with its free or stubbleward end on the downward-projecting portion l on the plate d when not in use. rlhe lower fiange of the finger-bar can be extended toward the rear, as shown in Fig. 4, to form a projection for the track i2.

c' is a strip extending from the lower flange of the finger-bar to the plate a. Said strip is provided with a strip t" on its rear side, forining the track i2, in which the anti-friction rollers I3 and IA1 operate.

F designates the compressor. Oneor more of such compressors may be employed. (One is shown in the present instance.) Said compressor F is curved about as shown in Fig. 3 with its lower end bifurcated.

J is a perforated block or ferrule provided with studs J, by which it is pivoted in the bifurcation of the compressor F.

J2 is a rod provided with an anti-friction roller J3 on its lower end to operate on the plate a. Said rod extends through the fer- IIO rule J and is provided with an eye J5 near its upper end to receive the forward-projectin g end of lever j.

J4 is a spring coiled on the rod J2, bearing with its lower end against the ferrule J and with its upper end against the shoulder formed by the eye J5. l

,7'4 is a block secured on the lower side of the plate a on the rear side of the slot A2 and near the stubble end of the track 72, as shown in Fig. 3. Said track jg is formed as shown in Fig. 4, having its ends S and S turned back orrearward, as shown in Fig. 1,and inclined, as shown in Fig. 3, to correspond to the inclined portion of the chain e.

j is a two-armed lever having anti-friction rollersj and j2 on the free ends of its rearward-projecting arms to operate in the track 75. Said lever j projects forward through the eye J5 of the rod J2 with its end extending to and beneath the upper strand of the chain e.

75 is a spring secured with one end to the sill B (near the stubbleend of the sill) and with its other and free end pressing against the rear of the compressor,as shown in Fig. 1.

The chain e is provided with inwardly-projecting lugs e2, e3, and e4. The lug e3 operates on the studs t and t to operate the starting mechanism and is located on the front edge of the chain e about two feet in front of or stubbleward from the conveyer. The lug e2 is located on the rear edge of the chain e and is to operate on the lever j to operate the compressor F and is placed about two feet stubbleward from the lug e5. The lug e4 is also located on the front side of the chain e and about six or eight feet stubbleward from the lug e2 (said distance depends somewhat on the size of the machine and length of the platform) and is to operate on the lever I2 to operate the discharger-bar I. Said lug e4 is placed on the lower strand of the chain e far enough from the conveyer or 1ug-c2, so that the grainward movement of the conveyer and upper strand of the chain e ceases as the lug e4 nears the roller o. The studs t and t project only to the center of the width of the chain e', and thus are not operated by the lug e2, and the lever j also only projects to near the center of the width of the chain, and thus is not operated by the lug e2.

The ends of the track i2 are turned back the same as thetrack js, as indicated in Fig. 1.

The plate et is out out at J7 for the operation of the compressorF shown in Fig. 1, and J8 is an opening made in the plate a for the reception of the needle shown in Fig. 3.

u isa bracket secured to the under side of the plate a and on the front side of the slot A2 and near the grain end of the track i2, projecting with its free end rearward over the chain e and provided with an anti-friction roller u in position to operate on the chain e toguide said chain. u is a similar bracket secured to the post B6 with its anti-friction roller o in position to operate on the lower strand of the chain c. Said bracket v and roller fu and a part of the post B6 are omitted from Fig. 3 to show the construction of the compressor and are shown in Fig. 10.

R is the main operating-arm of the conveyer, pivoted near its'center to the conveyerblock R4 and provided on its lower end with an anti-friction roller R to operate on the plate a and having pivoted to its upper end an extension R2.

R3 is a rod pivoted with its lower end to the conveyer-block and with its upper end to the grainward end of the extension R2, as more fully described in the patent issued to me, No. 446,473, dated February 17, 1891. The conveyer-block R4 is made about the same thickness as the chain e. Said chain e is secured to each end of the conveyer-block R4 with its upper side flush with the upper side of the conveyer-block R4, as shown, to operate under the guide-roller u, as shown.

197 is a spring secured to the bracketC, projecting with its free end grainward in position to engage with the cogs b9, as shown.

The bevel-pinion b is partly broken away in Figs. 2 and 10 to show parts beyond in full lines.

The parts are constructed and arranged to operate as follows, viz: The bevel-pinion b receives its movement from mechanism (not shown in the drawings) and operates the shaft C, which in turn operates the pinion b by means of the clutch b2. Said shaft C also operates the conveyer by means of the sprocket-wheel e and chain e. As the conveyer moves stubbleward with the gavel of grain the lug e2 comes in contact with the forward-projecting end of lever j, moving it stubbleward, thereby shifting the compressor in position, as seen in Fig. 3. As the compressor receives its proper position the roller t72 will reach the portion S of the track js, thereby moving the lever j to an angle to vthe chain e and back to some extent, allowing the lug e2 to spring the chain e and pass the lever j. As the lever j is moved rearward it also moves the upper end of the rod J2 rearward and behind the block j4, (see Fig. 3,) thus preventing the rod J2 from moving grainward when notso desired. The compressor receives its elasticity of compression from the springs J4 and L75 and is preferably made of spring-steel of proper thickness, so that it can yield to some extent after the capacity of the springs J4 and t7'5 have been absorbed. After lthe leverj is4 moved to the position as seen in Fig. 1 it is moved far enough rearward, so that the lug e2 can spring the chain and pass the end of said lever and again engage with it as the lug e2 is moved grainward. Next the lug e3 comes in contact with the stud t on lever t8, moving it along, moving the lower end of said lever t5 grainward, drawing the rod t9 in the same direction, and thus unlocking the shaft o3. At this time the lug e2 moves against the stud t on lever t2, moving it along, (stubbleward,) as

IOO

seen in dotted lines in Fig. 3, when it will spring the chain upward and pass the stud t. Said movement of lever t2 causes the shaft CZ to make about one-fourth revolution, which brings the needle or binder arm b5 far enough down to grasp the grain brought in by the conveyer, as shown in dotted lines in Fig. IO. At this time the movement of the conveyer is reversed, and the pinion b', being now operated by the clutch b2 and in engagement with the cog-wheel b4, will rotate the latter until the blank bs is again opposite the pinion b', as seen in Fig. lO. The momentum of the cog-wheel bt causes it to move far enough to allow the pinion Z7 to rotate in the blank bs clear of any friction until the shaft d is again started, as described. As the conveyer moves grainward, the lug e3 moves against the stud t', moving the lever t2 back again, as seen in full lines in Fig. 3. Next it moves the lever s back again, as seen in Fig. 3. Next the lug c2 moves against the lever j, moving it along, thereby drawing in the compressor in posi` tion, as seen in dotted lines in Fig. 3. At this time the lug e* comes in contact with the lever I2, moving it stnbbleward, thus operating the discharger-bar and discharging the bound sheaf. As the roller I4 reaches the ends of the track i2, bent forward, the lever I2 will move forward and to an angle to the chain c', allowing the lug c'l to spring the chain and pass the lever. At this time the grainward movement of the conveyer ceases. As the conveyer is again started on its stubbleward movement, the lug e4 comes again in contact with the lever I2, moving it grainward, thus drawing in the discharger-bar in position, as indicated in Fig. 6.

Then the shaft CZ is started, as heretofore described, the cogs b9 will engage with the pinion b', the spring bl preventing any rearward movement of the shaft CZ, and when the movement of the conveyer is reversed the pinion b operates the cog-wheel b4, as described.

rlhe studs 15 and t are only indicated in Fig. 3, as they are on the rear side of the levers t8 and t2.

The lever t2 when in position, as seen in full lilies in Fig. 3, rests with the lug tw against the post B6, and when moved, as seen in dotted sides in Fig. 3, it rests on a stud e, secured in a suitable position in the sill B', as shown in Figs. l and 3.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
