' Specif cation forrningpart of Letters Patent No. 177,616, dated May 23, 1876; application filed February 15, 1875.

I I "do hereby declare the following to be a full and exactdescrip'tion of the same, reference being bad to. the accompanying drawings, forming part of .this specification, in which- Figure 1 is a top view of my machine,

showing the general plan of the whole, a por 5 tion of the grain-platform being broken away to'show the raking mechanism. Fig. 2 is a vertical sectional view taken through the line w 00 Fig. 1, and shows the rake and manner of operation. Fig. 3 is a vertical sectionalI view taken through the line m :0 and shows the rake-operating mechanism. Fig. 4 is a rear elevation of thecompressing.mechanism. Fig. 5 is a verticalsectional view of the compresser-operating mechanism taken through the line :0 m Fig.6 is an enlarged top view of the band-forming mechanism, parts being removed to show more clearly the construe tion and manner ofoperation. Fig. 7 is a similar top view of the band former, the ma. chi i'e being adjusted so as to form a different style of band. Fig. 8 is a detached side view of the band-forming needle, showing the construction and manner of operation. Fig. 9 is a detached side view of the reciprocating throat, 92. Figs 10, 1'1, and 12 illustrate the different forms of bands and the-manner of forming the same. v

My invention relates to that class of harvesters easily convertible from'amowing to a reapingmachine, and vice versa; and this part of my invention'relates to devices whereby the grainis compressed and bound by means of a continuous binding formed by interweaving or braiding together the buttends of the straws on the outside of the sheaf while it is being compressed and rotated, a separate application being made for the novel 1 features of the machine as adapted only to cutting grass or grain, with or without the gathering-platform. This part of my invention consists in an extension rake-head, which moves forward beneath a secondary taper platform, and rearward over the same, and

operated by means of an endless chain; in a binding-mechanism, consisting of reciprocat ving needles which knit or braid the endless band about the sheaf; in an improved holding and rotating device; and in the arrangement and construction of the various elements hereinafter more fully described, and specifically claimed.

' Similar letters and numbers of reference, where they occur in different figures, indicate corresponding parts inall of the drawings,

To enable others skilled in the art to make and use my invention, I will proceed to dea, as alsodoes the rear end of the countershaft a for the purpose of supporting and connecting the binding mechanism. The finger-bar 12 is strongly connected to the main frame by means of the braces f and 6, and the secondary'tongue or pole d, and in such a manner as to allow the bar 12 to float upon the surface of the field whenmowin-g, and permitting the outer end of the said bar to play Vertically relative. to the main frame when'adjusted for reaping. v

To the edges of the platform 131 'aresecured the vertical sides 606 and 501, the latter of which is placed as near the inner drivewheel as possible. It is therefore somewhat which is securely, but adjustably, connected.

with the said inner side 501. The object of this arrangement is to adjust the tension of the chain 64. The rear chain-pulley is secured to the shaft 601, and receives motion from the gear-wheel 76 by means of the couplings 45. The chain 64 is provided with. a bloclclink, 52, to which is pivoted the rear end of the lever 54. The forwardend of the said lever is pivoted to the short lever 51. The said short "ing them in position.

- der side, the said studs moving within the grooves or guides 59 and 55-in the platform 131. To the forward side of the carriage 46 is pivoted the rake-arm rod 48, which is, by means of the arm 47, rigidly connected with the extension rake-head 41. The said rakehead 41 consists of three (more or less) parts,

which telescope within or past each other. The end piece 43 is provided with the frictionrollers 58 and 59, the latter of which plays within the groove 56 as the rake is beilfg moved forward, thereby extending the rakehead to the full width of the forward end of the grain-platform. 47 is the grain-platform, and is secured to the outer side 606, forming the opening 607, as shown in Figs. 2 and 3. To the inner side of the said platform 47 is secured a ledge, 65, which has for its purpose to prevent the falling grain from coming in contact with the rake-operating mechanism. The door 35 is hinged to the rear end of the grain-platform 47 by the hinges 44, and is provided with a ledge on its inner side, so as to form a continuation of the ledge 65. To the outer forward corner of the door 35 is a short a hanging lever, 608, which extends downward,

and connects with the rod 609, which is secured to, and plays within, a recess in the lower platform 131. The rear end of the said rod 609 is provided with a stud, against which the carriagc 46 strikes, for the purpose of raising the door 35, in the manner and for the purpose hereinafter described. The chute 62 is rigidly connected with the bottom l31-and the sides 606 and.501. The bevel-wheel 74 receives motion from the shaft a and meshes with the wheel 76 upon the shaft 612, thus, by means of the clutch 77, giving motion to the raking mechanism.

The operations of the rake are as follows: A gavel having accumulated upon the platform 47, the operator, by means of the shipper-lever 78 connects the clutch 7 7,-which gives motion to the chain-pulley 60, and by means of the chain 64 moves the carriage 46 forward.

The rake 41 passes through the opening 607. The link-block 52 in passing around the forward pulley 60 depresses the rear end of the lever 54, andby means of the short lever 51 and the connecting'rod 50 raises the rakehead 47 to a vertical position, the block-link passes into the groove 613, thereby holding the lever 54 down and the rake in position, and moving the carriage and rake rearward, the studs within the grooves 59 and 55 hold- The friction-roller 58 impinges against .the outer side 606, thereby contracting the rake head and the gavel, which is being swept rearward along the wed ge-shaped platform and through the chute 62 to the binder or to the ground, as may be desired. The'carriage having nearly reached the rearward extent of its movement the arm '4 46 strikes against the stud on the rod 609, carrying the hook 610 against the arm 608, thereby raising the door 35 to the position shown by the dotted lines, Fig. 2. The block-link 52 now passes upward around the rear chainpulley 60, raising the rear end of the lever 54, and thereby throwing-the rake-head down upon the lower platform. The friction-roller 59 then passes into the groove 56, the carriage and rake move forward beneath the grainplatform 47, and, relieving the stud-rod 609, the door 35 drops into its first position, and the groove 56 extends the rake, as before described. The operator now, by means of the shipper-lever 78, releases the clutch 7 7, and the rake stops until another gavel accumulates upon the platform.

chine is used for depositing the gavels on the stubble without binding, and the said platform may be curved and extended so as to place the gavels as far from the standing grain as may be desired. To the rear ends of the main-frame rails B B is securely but detachably connected the obliquely-extending arm 63, which has for its purpose to form a frame and support for the binding mechanism. To the arm 63 are connected the curved arms 142. These arms serve as guides for the curved compressor-arms 67, which are provided at their outer ends with hooks or slides,

which clasp the guides 142. The said coinpressor-arms 67 are pivoted to the main arm 63, and are connected by the connecting-rod 130, so as to operate together. The pulleys 172, 102, 152, and 103 are pivoted to the arms 67, and carry the compressing and rotating cord around the gavels. To the rear end of the shaft a is secured the pinion 68, which meshes with the wheel and. pulley. 61, which latter turns upon the stationary stud a, as

' also does the crank-disk 66. In the outer side of the wheel 61 is a groove, which is provided with internally-projecting teeth, with which the pawl 132 engages, thereby communicating motion to the crank-disk 66. The spring 128 depresses the pawlarm 129, thereby keeping the pawl-arm against the said teeth, except when raised, ashereinafter described.

To the wrist 135 is pivoted the connectingrod 125, the opposite end of which is pivoted to the arm 69. The studs 126 and 127 strike against the pawl-arm 129, for the purpose of releasing the pawl 132. By this arrangement the connecting-rod always stops at each extreme of its throw or movement, thereby always stopping and holding the compressor open or closed, and its movements are governed by the lever 79, which is pivoted to the outer main-frame rail B, and is provided at its lower end with the spring and pawl 80. The said pawl engages with the teeth 0 in The'object in hav-. ing the lower platform open is to allow fragmam a the crank-disk 66, for the purposes before mentioned, and in the manner hereinafter described. The web 121 hangs loosely upon the rollers 101 and 104 and the central pin a"'. The

- rollers 101104 are pivoted to the arms 108 107.

out of the binder, and to support the top end of the sheaf while being rotated and bound.

The cord 14 passes around the driving-pul-- ley 61; thence around the stud-pulley 105, to

the tightening-pulley 17,4; thence around 105;

- thence to the arm-pulleys102, 172, 150;aud

103; thence back around 105 and 106 to the 1 driving-pulley 61. To the upper ends of the curved arm's 142 is connected the plate or frame 118, (shown in Fig. 6,) to the inner end of which is connected the standard 147, in the top of which are bearings for the shafts and a". The lower end of the shaft 70 is pivoted to the arm 63, and receives motion, by means of the bevel-wheel 72, from the bevelwheel 76; The tops of the shafts 70 and a are provided with gears 82, and the lower end of the shaft (17 is pivoted to the frame 118, and carries the grooved disks and 119, in the lower of which is a heart-shaped groove, in which play the pivots 0r friction-rollers 86, on the levers83 84. One end of the said levers is pivoted to the frame 118. The other end is,

, only used in the arrangement shown in Fig. 8.

The ends of the needles 88 are beveled off on their under sides to a point, as shown in Fig.

8, and are provided with the eye 89. a is a tine pivoted to the side of the needles 81, near the eye 89. The end of the tine is provided with a vertical arm, which is connected to the frame 118, by means of the coil-spring of. The inner ends of the needle-shafts 81 are provided with a slight vertical play or movement, and are scalloped at e, which enables the said needles to pass over each other alternately when in operation. and 87 are curved guides, which are firmly but detachably connected with the framellS, and have for their purpose to deflect the thread-of straw from the top of the needles, causing the said nee-' dles to take up the same wisp of straw at each movement, thereby using the entire length of the straw.

' 71 is a tined disk, pivoted to the vertical supports 73, and receiving, motion from the shaft a by means of the cord 87, and has for its purpose tocarrythe end of the braid or band against the needle, so as to connect the first and last formed ends, thereby making an endless band. T T are two tines, securely connected to frame 118 at the'opposite sides of the opening 520, and project in the direction in which the gavel is rotated. The band or braid is formed around these tines, which hold the said braid while being formed by the needles, and passes off the points as the gavel is revolved. To the forward side of the arm 63 is attached the eyebolt 64., for the purpose of receiving the hook 53 for attaching and sup porting the rear end of the platform.

By this construction the fin ger-bar is allowed to follow inequalities of the field, and the rear end of the platform oscillates upon the eye- 'bolt without materially interfering with the operations of the binding mechanism.

To the sides of the chute 63 is attached the I leaves 61, which have for their purpose to de-,

flect'the grain and straggling straws into the binding mechanism.

The operation of the binder is as follows: The operator, being provided with a suitable seat within reach of the levers 78 and 79, causes the grain to be raked into the com pressor, as before described. The lever 79 is then raised. The pawl 80 engages a tooth in the disk 66, revolving it a little, when the stud 127 slips past the pawl-arm 129. The spring moves the pawl 132 so as to engage a tooth in the wheel and pulley 6l,whieh causes thecrankdisk to turn one-halfof a revolution, when the stud 126 strikes against the pawl-arm 127, thus disengaging the crank-disk 66, and bring in g the compressor-arm 67 to vertical position,

carrying the cord around the gavel, raising and holding it against the tines T The web 121 is carried against the heads of the grain by the rollers 102 and 103, thereby balancing the rotating gavel upon the cord 140. One of the needles being withdrawn, the arm of the tine e strikes against the frame '118 at (F, bringing itinto theposition shown in Fig. 8. The return movement causes the tine a to take up a little of the straw of the gavel, which forms a loop, which is thrust over the tine T the tine a The opposite needle takes up a wisp of straw fromthe gavel at the opposite side of the frame 118.- In the same manner the and so on, forming a braid of straw about the gavel as it is revolved, as shown in Fig. 10. The first-formed part of the band, in coming around, is caught by the tines 71, and carried against the needles through-the opening 520, and is interwoven-with the last-formed part of the band. The connection being completed, the

operator raises the lever 79, which again causes the crankdisk to make another half ofa revolution, as before described, throwing open the compressor'arms 67, whenthe bound sheaf drops away from the binder, and is pushed out of thecompressor by the next gavel. Either of the tines a may be removed from The spring a closes the eye 89 by 'theheedles, when. the band will beformed,,as
