SPECIFICATION forming part of Letters Patent No. 496,797, dated May 2, 1893.

Application filed April 27, 1892. Serial No. 430.909. (No model.)

Summit, and State of Ohio, have invented a new and useful Improvement iu Grain-Binders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

Our invention relates to that class of grain binders employing a needle trip, or means connected with and operating through the needle to trip and release the binder mechanism, and requiring, for this purpose, a yielding pitman which will allow the needle shaft and needle, whenl the latter is in position to receive the grain, to vibrate sufficiently to release and set the binder mechanism in motion.

The object of the invention is to produce a simple, elfective and inexpensive construction of trip of the kind referred to and also to improve the grain compressing devices and bring them into compact and effective `arrangement; it will be understood from the following description and claims, reference being had to the drawings, in which- Figure 1 represents a vertical section through the binder, showing the needle, one packer and the compressor mechanism in side elevation and in position to receive the grain. Fig. 2'is a similar view with the parts in position for compressing the grain for binding,

&c., and Fig. Salso asimilar View of the parts after the binding has been completed and the bundle is free to be discharged from the machine. Figs. 4, 5, 6, 7, 8, 9, 10 and 11 show, in detail, parts of the machine, hereinafter referred to, detached. Fig. 12 is a plan view, partly in section, with the binder table broken away and the compressor removed to show other parts. Fig. 13 is afront elevation showing the arrangement of the needle actuating mechanism and of the devices for tripping the same, and Fig. 14 is a similar View of the needle shaftcrank-arin, pitman, tbc., showing said parts in a different position from that shown in Fig. 13.

The binder frame is composed of the longithe frame beyond the sleeve B and is united to the sill A4 and through the latter to the outer sill A, the parts referred to forming a strong, rectangular frame, upon which the binder table C is supported in any usual manuel'.

The sleeve B extends a short distance beyond the intermediate transverse sill A3 and has the needle shaft D journaled in it and upon this shaft the needle D is secured, adjacent to the end of the sleeve and intermediate the sills A3 and A4, as shown in Fig. 12. The shaft D extends beyond the needle and may be further journaled in the sill A4 or in the sleeve or plate B2 secured thereon and to the sill A.

The sill A3,shown in side View, Fig. 4, andy n plan View, Fig. 5 is provided at its outer end Awith a socket at a, for the sill A; intermediate its ends with a pendent bearing sleeve a in which the packer shaft is journaled and near its inner end, is bolted to lugs on the sleeve B', through a horizontal flange on its upper edge. The sill extends beyond the point ofv attachment to the sleeve B and is provided on said extension with a stud'or pivot for one of the packer links and below the latter, at its end, with a depressed bearing sleeve for the vibrating bridge, as will appear.

The needle D has a heel extension beyond its shaft D and to this extension the bifurcated end e of a compressor bar e, is pivoted. The form of this bar is shown in plan view Fig. 6; it is provided in its bifurcated endy with a pendent perforated ear e2 in whicha set screw e3 is secured forming an adg ustable stop acted upon by a pendent spur d, on the needle for restoring the bar e to and holding it in operative position as will appear. In-

termediate its ends the bar e is provided with astud pivot e4 on which a roller f is mounted.

g is a compressor frame made in form substantially as shown in detail views, Figs. 7, 8 and 9, having two upright sides which em- ICO `brace the bar c, between them and are united by a horizontal flooring which extends beyond the rear, upright part in the form of a ledge g provided with a pin or extension g2 for a purpose which will appear. The inner end 0f the frame g is provided on one side with a flange g3, perforated to receive a bolt h passing through the base of the fork on the end of the bar e, the head of the bolt resting in said fork, as shown. The bolt h, outside of the flange g3 is surrounded by a spiral spring h', the tension of which is regulated by a nut h2, adjustable on the outer end of the bolt, and is exerted to hold the frame g against the forked end of the bar e. The outer end of the spring h and bolt h are upheld by the ledge g and a loop g4 on the outer end of the frame g. Above the loop g4 is a friction roller g5 journaled in the upright sides of the frame g and resting and rolling on the bar e and inward from said roller. The side plates are provided with a pinV or bolt att' on which the compressor I is mounted, said compressor being provided at c" (Fig. 11) with two or more perforations permitting its adjustment on the pin c', to regulate the size of thebundle.

The foot of the compressor rests and slides, with the frame g on the bar e and above the plane of the pivot and in rear thereof, the compressor is provided with horizontal lips or flanges 2 which rest on the upper edges of the sides of the frame g and serve to uphold the compressor against the backward thrust of the grain.

The side of the compressor frame g adjacent to the roller f, is cut away at g6 to permit it to pass said roller, sufficiently to allow the inner end of said frame to abut or be drawn against the shoulders of the fork of the bar e.

To theinner pendent sleeve d2 of the sill A3 is pivoted an upright arm J, shown in rear elevation in Fig. l0, the upper end of which underlies the roller f and is provided with a ledge j, V-shaped on its lower face and upon which said roller descends when the compresser bar c is forced downward by the pressure of the grain. Inward from said arm,which constitutes what we term the vibrating bridge, the 'sill A8 has a dange or ledge a3, formed on it slightly curved or inclined downward on v its end adjacent to the bridge J and outside of and below said ledge the sill is provided with stops or spurs erfand a5, between which an arm J on the bridge J extends, said stopsserving to limit the extent of vibration of the bridge, which is upheld in its normal, upright position by means of a spring j', secured to the sill A2.

vThe sill A3 is further provided at d6 with a pin or stud on which the link kof thepacker K adjacent to said sill, is pivoted, and, on its lower edge with a horizontal arm or stop a7, whichfprojects under the compressor frame e-and limits its downward movement.

` To the frame sill A is secured a sleeve L provided with two rods or long fingers Z, l,

which extend up through the needle slot in the table, one on each side of the needle and across the table, and the forward one of these, overlying the roller f is provided with a pendent spur Z', which, when the compressor and compressor bar c and roller fare in their normal position, rests on said roller and upholds the outer ends of the rods Z above the binder table, as shown in Fig-1.

The compressor is upheld in position to receive the grain, by means of the spurcl on the needle abutting against the stop or set screw e2 on the compressor frame and the grain being forced against the compressor and back on the rods Z, by the packers K, K, acting in the usual manner, when enough has accumulated to form a bundle, the pressure of the grain outward on the compressor `and downward on the rods Z,is sufficient to depress the bar c, overcoming the resistance of the needle and vibrating the latter and its shaft sufficiently to release and set in motion the binder mechanism, as will appear. j

To the forward end of the needle shaft D is secured a crank arm D2 from which a pitman extends to a crank pin on a bevel gear M on the knetter actuating shaft and from which a vibratory movement is imparted to I the needle shaft in a well known manner. Motion is communicated to the gear M through the shaft M and suitable connecting bevel pinions from a bevel gear M2 on the packer shaft K2. The shaft K2 has a continuous rotary motion imparted to it in any usual manner and on its forward end has a cross head 7a2 provided with rearwardly projecting pins carrying friction rollers k3. The gearM2 is loose on the shaft K2 and is provided with a dog 7a4, having a spur held, normally, in engagement with one of the rollers k2 for engaging the gear M2 with its shaft, in any well known manner.

The crank arm D2 is provided with a trip arm D2, which, as the needle approaches its position of rest to receive the grain, comes in .contact with the projecting arm of the dog 7a4 and throwing the latter out'of engagement with the shaft K2, trips the binder mechanism and allows the latter to rest until enough grain has accumulated to form the bundle and the pressure thereof acts on the needle as explained, to vibrate it, and the arm` D2 and raise the latter to release the dog b4 and set the binder gearing again in motion. To permit this vibration of the needle shaft and arm D2, it is essential that the pitman connecting the needle shaft with its actuating crank, should be adapted to yield and to this end the pitman is jointed at or near the center of its length, one part m thereof being provided with a short rigid arm m2 overlying and extending beyond the hinge vconnecting it with the part m and forming a stop to make the pitman rigid in one direction. .The part m is perforated, near the hinge to receive a bolt fn, which passes through the arm m2 and outside thereof is surrounded by a IOO IIO

ISO

spring n and a nut n2, by adjusting which,

the tension of the spring can be adjusted Vasdesired.

Below the joint in the hinge, the part mis provided with a threaded nut or perforation at o, to receive a set screw o', which is so adjusted as to come in contact with the crank arm D2 near the needle shaft, just before the needle reaches itsl position of rest, thereby breaking the jointin the pitman, as shown in full lines, Fig. 13, deilecting said pitman from the right line, shown in dotted lines l. pressure is brought by the grain on the compressor and through the latter on the needle, as above explained, the pitman is still farther deflected, assuming the position shown in dotted lines 2, Fig. 13, thus allowing the arm D3 to be rocked up out of the way of the dog 164, releasing the latter and allowing it to engage the bevel gear M2 with its shaft K2 and thus to set the binder mechanism in motion. The set screw o', instead of being on the pitman, may be applied to the crank arm D2, as shown in Fig. 14,.with the same result.

kThe packer shaft and packers are of a well known form, one of the packer links la, being pivoted to a pin on the sill A3 as explained. The other packer link k is pivoted to an arm b on the sleeve or plate B2 and the latter is also provided with a pendent lug, shown at 10 (in dotted lines Fig. l2) to which one end of a link p is connected, the other end of said link being connected to a link p2, which at its outer end is connected to a pendent arm p3, secured to a hinged, leaf extension C of the binder table.

The operation, beyond what has already been described, is as folloWs:-Supposin g the parts to be inthe position shown in Fig. 1,

the grain'is carried in by the packers against the compressorI until the pressure on the latter and on the rods Z, forces the compressor bar e downward, until the roller f rests on and is upheld by the upper end of the vibrating bridge or arm J. By this movement the needle is vibrated and the dog 104 released, when the binder mechanism is set in motion as explained. As the needle is now farther vibrated, the bar e and the compressor frame g through their connection with the needle, are drawn forward, carrying the compressor toward the needle and the bridge J, supporting it, is carried inward as shown in Fig. 2, by the roller f, until the latter reaches and is drawn on and supported by the ledge 0.3. This releases the bridge J which is immediately retracted by the spring to its normal position. When the needle starts back to receive a new bundle, the roller f drops o the ledge a3, and falling down between the ledge and the bridge J, allows the compressor frame and bar to dropdown on the stop a7, the parts assuming the position shown in Fig. 3. The links p,192, upholding the hinged leaf C of the binder table, are supported in the position shown in Fig. 1, for that purpose, by the `pin g2 on thecompressor frame g, and as the latter descends, the toggle link 102192, is left unsupported and the leaf' C falls into the horizontal position shown in Fig. 3, thereby leaving the binder table clear, outside thebundle, for the free discharge of the latter, after which, in the farther descent of the needle, the spur d acts onV the stop d5 on the compressor bar, vibrating the latter upward and with it the compressor frame and compressor to their normal position shown in Fig. 1. The roller f, in rising, comes in contact with the outer, upwardly inclined, lower face of the ledge j on the arm or bridge J and crowds the latter ledge, when the spring j restores the bridge to'position to again receive and carryrthe roller inward. In this return movement of the compressor mechanism, the pin g2 acts on the link p and through the latter on the leaf C to raise it to the upright position 'shown in l Fig. 1. TheV spring 72. lies substantially parallel with the' bare and allows thecompressor to yieldoutwardly, underthe pressure of the grain, thereby increasing the leverage of the compressor for depressing said bar. The operation of the other parts will be readily understood.
