IMPROVEMENT IN BAKING- .AND BINDING ATTACHMENTS T HARVESTERS- Specification forming part of Letters Patent No. 54,672, dated May 15,1866.

To all whom it may concern:

Be it known that I, JOSEPH BAR'IA, of La Grosse, in the county of La Orosse and State of Wisconsin, have invented a new and Improved Raking and Binding Attachment for Reapers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1, Sheet N o. 1., is a plan or top view of my invention; Fig. 2, a vertical section of a portion of the same, taken in the line mm, Fig. 1; Fig. 3, a detached view of a part pertaining to the same. Fig. 4, Sheet No. 2, is a side view of the same; Fig. 5, a vertical section of the same, taken in the line y y, Fig. 1; Fig. 6, a vertical section of a portion of the same, taken in the line 2 2, Fig. 1; Fig. 7, a vertical section of a portion of the same, taken in the line w m, Fig. 1. Figs. 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 1s, 19, and 20, Sheet No. 3, are views pertaining to the knot-tying and cord-cutting mechanism.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and improved raking and binding attachment for reapers, designed to be operated automatically throughout from the driving-wheel of the reaper to which it may be applied.

The object of the invention is to obtain a device for the purpose specified which will be capable of being put in motion at longer or shorter intervals, as occasion may require, and be also capable of being adapted for binding long or short grain.

I will first proceed to describe the driving mechanism, by which the device is operated. A representsthe framing of a reaper, and B B standards attached thereto, in which the bearings G of a horizontal shaft, D, are fitted. On one end of this shaft a wheel, E, is placed loosely, so that it may turn independently of the shaft, and this wheel E has a ratchet, F, attached concentrically to its inner side. G is a wheel attached permanently to the shaft D, and having a recess or notch, a, made in its edge,'as shown clearly in Figs. 5 and 6, and His apawl which is attached to one end of -a shaft, 12, which has its bearings in arms 0 attached to the shaft D, said shaft passing through the wheel G, and having a lever, H", attached to it, which is by the side of the notch a at one end of the same, a. spring, d, bearing against said lever in order to keep the pawl Hengaged with the ratchet. I is a plate attached to the upper part of a vertical shaft, J, and having a spring, 0, bearing against it, which spring has a tendency to keep the plate I in line with the lever H. K is an upright shaft, which has an arm, f, pro; jecting from it, and passing through an eye or loop, g, attached to plate 1. From the lower part of this shaft K a lever, h, projects, with which pins 1 on the inner side of the wheel E come in contact. These pins i are arranged in concentric circles at the inner side of the .wheel E, said circles of pins varying of course in diameter, gradually decreasing in diameter as they approach the center of the wheel, and only one circle of pins operate against the lever h at a time, and said lever may be brought in range or line with any one of said circles by raising or lowering the shaft K, which is done by means of a lever, L, the lower end of which is connected by an arm, j, to the lower end of a bar, It, the upper end of the latter being attached to the upper end of shaft K. The shaft K is retained. in the de sired position by having the leverL fitted in a proper notch in a segment-bar, M, attached to one of the uprights B.

The office of the pins i and lever h is to draw the plate I out of line with the lever .11, so that the pawl H may be kept in contact with the ratchet F, and motion be communicated from wheel E to shaft D.

It will be understood that when the plate I is in line with the lever H, the latter will come in contact with the former, and the pawl H will be thrown out from the ratchet F, consequently the wheel E and ratchet F will rotate without communicating motion to shaft 1), but when a pin, t, strikes the lever h, the plate I is drawn out of line with the lever H and the spring (1 immediately throws the pawl H in contact with the ratchet F. When the plate I is thus drawn out of line with the lever: H, the wheel G catches in a groove in the edge of said plate and keeps the lever it out free from the pins t, so that the latter cannot be acted upon by the former, and the spring 0 throws the plate I out of line with lever H when the notch a of the wheel G comes opposite the plate I.

From the above description it will be seen that the shaft D will be rotated at longer or shorter intervals, according to which circle of pins t the lever It is adjusted in line with. For

instance, if the outermost circle has six pins i, the shaft D will rest during one revolution of wheel E, the time said wheel makes onesixth of a revolution, and if the innermost and smaller circle has but one pin i, the shaft 1) will he rotated one revolution during every ,two revolutions of awheel, E, D rotating one revolution, with E remaining stationary the next revolution, and moving with it the succeeding one, and so on. v

Thus it will be seen that the binding apparatus may by a very simple adjustment on the apparatus, which takes the cut grain from the platform and deposits itin the binding-cradle. The platformof the reaper is not shown in the drawing, but it isdirectly in front of a bed, N, which extends out from the frame of the machine, and has a metallic sliding frame, 0, upon it, fitted between guides Z This frame 0 is of curved form, as shown clearly in Fig. 1, and it is slotted its entire length, and has a plate, P, fitted upon it, one end of which is bent or curved to form an eye to receive the rake-head Q, which is allowed to turn freely therein. The rake extends over the platform, and is at right angles with the sickle or cutter, the portion of the rake-head which is fitted in the eye of plate P being at right angles with the part to which the rake-teeth are attached, and to the outer end of the rake-head adjoining the eye there is an arm, m, which is connected by a rod, '41, with a bent lever, 0, on plate P, and this bent lever o is connected bya link, 12, with a lever, q,- on plate P, said lever q having its free or disengaged end connected by a rivet with a plate, R, underneath or within the frame 0. (See Figs. 2 and 3.) S is an endless chain, which works around pulleys r on the bed N within the frame 0, and around a pulley, T, on a shaft, 3, which has a pinion, t, on its inner end, said pulley T beingturned first in one direction and'then in the other in consequence of a part pinion, U, and a toothed segment, V, on a wheel, W,gearing alternately into the pinion t, the wheel W being on the shaft D To the chain S a staple, X, is attached, through which the plate R passes, and by this means the rakehead is connected with the chain S and a reciprocating motion given the rake over the platform. As the rake is moved from the inner to the outer side of the platform the former is held in an upright position, so as not to interfere with the cut grain falling thereon in consequence of the staple X pressing against the plate R in the direction indicated by arrow 1., (see Fig. 1,) and during the return movement of the rake it is kept down upon the platform in consequence of the staple X bearing against, plate R in the direction indicated by arrow 2. The rake is prevented from making aretrograde movement while traveling in either direction by means 'of two pawls, n a, which engage alternately with a rack, 0, on the frame 0, said pawls being freed from the rack by the bent lever 0','when the latter is moved to raise and lower the rake. (See Fig. 1.)

t The frame 0 I termed a sliding one, in consequence of it being capable of adjustment on the bed N in a longitudinal direction there with, soas to be nearer to or further from the outer end of bed N; This adjustment of the frame 0 admits of the cut grain being delivered to the cradle centrally therewith, the adjustment compensating for the variation in the length of the grain. When long grain 'is being cut the frame 0 is adjusted outward, on the bed N asfar as possible, and adjusted'inward when short grain is being cut. The frame 0 is moved by means of a lever, A, having a crank, B, atits lower end, which crank is connected by a rod, it, with frame 0.

(See more particularly Figs; 1 and 6.) 0

represents the cradle into which the cut grain is discharged by the rake. This cradle is composed of a series of curved .teeth, o, extending from a plate, to, the ends of which are provided with journals fitted in eyesa at the front edge of an inclined bar, b,on the framing. This cradle is allowed to work freely up and down on its journals as centers, and the outer tooth 'v at one end oi'the'eradle has a plate, D, attached to it, saidplate having a notch, a, made in it, to receive a projection, d, on a bar, E, the ends of which are bent at right angles with its main portion .to form arms (I, which are pivoted to uprights c c on the framing of the machine. This bar E is raised and lowered by means of a lever, F, which has a part pinion, f, attached to it concentric with its fulcrum-pin 9, said part pinion f having two sets of teeth, hh",

into which respectively a concentric pinion, i, on the inner side of the wheel XV, and a toothed segment, j, on the same side'of said wheel,

gear alternately, thereby raising and lowering the bar E; (See Fig. 7.) When the bar E rises, the cradle G is also raised, in consequenceof the projection d of bar E catching into the notch c of plate D, and when the cradle is raised it is held in an elevated position by means of a catch, it, and the bar E is held in an elevated position by means of a catch, l. The bar E and the cradle O are released at the proper time by projections m on the shaft D, the bar being released a little in advance of the cradle. The cut grain is raked from the platform of the reaper into the cradle 0 when the latter is down, and by means of the adjustment of the frame 0, as previously described, the grain may be discharged centrally into the cradle, so that the cord may be passed and secured centrally around the sheaves. The cord is wound upon a spool placed on a horizontal shaft, 10, supported by uprights on a bar, g, on the upper ends of the uprights a c. The cord r passes through an eye or guide, 8, attached to the bar q, and then through a clamp,t, at the frontend of abent lever, H", placed on the top plate a of a case, I, which contains the knottying mechanism, the end of the cord being secured in aclamp, 1;, attached to bar E. When the grainis discharged into the cradle C it rests upon the cord 1", and when the bar E rises, the cord is drawn around the grain and is passed in to clamp t, a twister, J, being thrown forward with open jaws to w to grasp the cord, the twister being then drawn back, leaving the cord around a hollow square, a, on one of the jaws w. (See Fig. 17.) After the twister is drawn back it turns to give the twist to the cord, and after thetwist is given, a curved hook, b, passing through the eye and drawing the cord through the loop of .the cord, and thereby forming the knot. The twister J is rotated by a toothed segment, 0, attached to a pivoted plate, K, on the top plate a of the case I, said segment gearing into a pinion, (1, on the twister-shaft, and the twister is moved forward by means of a lever, 0, having a pin, f, attached, which is fitted in a curved slot, 9, in plate K, and the hook I) is moved from the plate K in consequence of a pin, h, attached to an arm on the hook passing through a slot, 6, in said plate. The plate K is moved by an arm, j, on a vertical shaft, k, operated from the shaft D by part pinions l. After the knot is tied the cord above the knot is cut by shears m on the bar E, the moving blade being connected to a slide, a, on bar E, and operated by a lever, L, which is actuated by a cam, O, on shaft D. The sheaf is retained in the cradle C while being bound by means of a lever or arms, 19, acted upon by cams g on shaft D, and when the knot is tied and the cord cut above it, the apron L is released and the bound sheaf rolls down the inclined bar 12, and raising the apron L, passes out. The bar E and cradle G are then lowered, the cord r extended down with bar E, and a succeeding gavel is raked with cradle C, to be bound as before.

ranged in concentric circles, and the ratchet F connected with said wheel, and both placed loosely on shaft D, in combination with the notched wheel G on shaft D, the pawl H provided with the lever H, and the plate I, all

arranged substantially as shown and described, for the purpose of rotating the shaft D, and consequently the raking and binding device, intermittently, at longer or shorter intervals, as may be desired.

2.
