E$PECIFICATION forming part of Letters Patent No. 367,852, dated August 9, 1887.

Application filed June 19, 1886.

tion, showing the parts in position to receive the cut grain; Fig. 2, a similar elevation showing the parts in position to compress the cut grain; Fig. 3, a similar elevation showing the parts in position as the cut grain is compressed; 7

Fig. 4, a similar elevation of the compressorarm, showing itsvposition for'the discharge of the bundle.

The object of this invention is to produce a device or apparatus for compressing cut grain into suitable gavelsto bebound in automatic or self binders, which will yield during theseparation of the grain, and compress a gavel in more than one direction; and its nature consists in the improvements hereinafter described and claimed as new.

In the drawings, A indicates a binding-platform, upon which the automatic or self binder is mounted, as in-the Fsterly machine, (shown in PatentNo. 266,254,)the impro vementshereinafter described being substantially based on said machine, and it is mounted upon a frame of gas-pipe or other suitable material.

B indicates the position of the breast-plate upon which the knotter is mounted; G, the needle-arm, which is of the usual form,having the rear extension operating as a separator or divider; D, the compressor-arm; E, the pivoted supporting-block; F, an inward or downward projection on the needle-arm; a, pivot of the compressor-arm and the tumbler E; b, slot in the compressor-arm; 0, pin or bolt passing through the slot 1) and connected with the support E; d, arm for operating the supporting-block E; d, shaft for operating the arm d,- c, link connecting the arm or lever d and the support E; f, adjusting -holes for giving the compressing-arm more or less movement; 9, arm or lever for operating the arm D in a forward direction; 9, shaft for operating the arm h, chain for connecting the arm 9 with the compressor-arm; 2', chain for similar to the Esterly or other machine, where r the grain is carried up over the drive-wheel by an elevator anddelivered onto a downwardlyinclined binding-platforn1, and the devices here shown and described areadapted to be operated with any machine which carries a knotting apparatus upon a breast-board lo cated in the position shown by the line B.

The needle, as before stated, is of the usual construction, except that on the side opposite its shaft it is provided with an extension, F, having holesj for receiving the clevis or link which forms a part of the chain 13.

l The compressing-arm D is best made in the form shown; but this form may be somewhat varied. This arm is pivoted to the supporting block or bar E at a by astud, pin, or bolt, as may be most convenient. It is provided, also, with a slot or opening, I), so that it may have a limited amount of movement inde pendent of the block'or bar E, with which it is connected by the pin 0 passing from said block through the slot 1). The bar E is made in the form shown, and is pivoted to the' p1*ojection F or upon the needle shaft. It may all be in one piece, or the pivotal extension may be made separately and be bolted on, and it has a vertical movement to the extent of the movement ofthe arm (I. This supporting block or bar E is connected by the link 6 with the operating arm or lever cl, by which it is held and operated.

The compressing-arm is connected with the projection F of the needle or needle-shaft by the chain 1', which chain may be adjusted by means of the holes j in the projection F. The compressing-arm is also connected with the partly-rotating arm or lever g by means of the chain h, which holds it when in the position shown in Figs. 1 and 2. v

I11 operation, the needle and the compressorarm are in the position shown in Fig. 1, when the'grain for the gavel or bundle is to be received, and grain may be forced down or in, by ordinary packers or other devices, against the arm D until the desired amount is collected. The needle then commences to rise; but before it rises the compressing-arm D falls backward to the position shown in Fig. 2, which relieves the pressure which the needle would otherwise have, and affords it an easy passage through the grain flowing to or resting upon the binding-table A, and thus affords an easy separation between the grain to be bound and the advancing grain. \Vhen in this position it will be seen that both of the chains h andi are nearly or quite taut, and from the position shown in Fig. 2 the further movement of the needle or its shaft brings the strain upon the chain 6 and causes the compression-arm to return with a movement equal to that of the advance movement of the needlearm C, so that when the needle is in position for the operation of the knotter or twister the parts will be substantially in the position shown in Fig. 3, where they are firmly held until the operation of the knotter is completed, thus giving the bundle a positive compression from both front and rear, and which, owing to the curved form of the acting parts, almosteneirclcs the bundle, giving it when formed a better shape than is given to it when the compression is from one side only, and this arrangement, also, as before stated, gives the needle a free and easy movement through the grain and an easy division of the gavel from the flowing stream of grain.

The shal'ts g d are extended out and operated by cams at their outer ends, which gives the arms or lovers 1 (Z their required movements at the proper times. XVhen the needlearm starts back, the arm (Z throws the compressor into the position shown in Fig. 4-, in which position the bundle is easily discharged from the machine. As the point of the needle passes below the breast-plate B the arms 9 and (I throw the compressing-arm into the position shown in Fig. 1, ready for the reception of a succeeding gavel, at which point it remains until the gavel is collected, when the described ope 'ation is repeated.

What I claim as new, and desire to secure by Letters Patent. is

1. The combination, with the needle-arm C and pivoted compressing-arm D, of the chain i, attached to the compressing-arm, and the projection F, located on the needle-arm and provided with a series of holes, j, for receiving a clevis or link on the chain 1 substantially as described.

2. The combination, with theneedle-arm C, chain 6, and pivoted compressingarm D, having slot 7), of the pivoted block E, having pin 0, engaging said slot, the link 0 and the lever (I, having adjustingholcs f for attachment of said link, substantially as described.

3. The combination, with the needlcarm O and the pivoted compressingarm D, of the arm 1 chain 7:, connecting said arm g with the compressor, the projection F on the needlearm, and the chain 1', connecting the compressor with said projection, the latter being provided with adjusting holes j for attachment of said chain, substantially as described.

4. The combination, with the needle-arm 0, having projection F, and the compressing-arm D,having slot Z), of the chain '1', connecting the projection F and arm D, the tumbler-block E, having a pin, 0, engaging the slot I), the lever 11, and the link 0, substantially as described.

5. The combination and arrangement of the arm chain It, pivoted compressor-arm D, block E, link a, and lever (Z, with the projection F and chain 6, substantially as set forth.

6. The combination, with the needle-arm 0, having projection F, and the pivoted compressing-arm D, of the tumbler-block E, ad-

justable link 0, lever (1, arm 1 and chains ll. 11,

substantially as described.
