T0 all whom it may concern:

Be it known that I, JOHN CI-IAMBERLIN, a citizen of the United States, residing at Flat Rock, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Tongue- Truck Turning Attachments for Binding-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to a tongue truck turning attachment especially designed and adapted for use in connection with binding machines and the like, and consists inthe novel construction and arrangement of parts as hereinafter fully set forth and pointed out particularly in the claims.

The main object of the invention is the provision of simple and efiicient means for employment in connection with the ordinary types of grain binding machines as now in common use, to facilitate the turning of the machine at the corners of the grain so as to present the cutter bar to the standing grain in the required position to enable the cutting of a full swath at any desired angle to the preceding cut without necessitating the backing of the machine or maneuvering with the team to attain such position.

The invention pro-vides for such a construction and arrangement of parts attachable to the tractive tongue, the tongue truck and the guiding tongue of the machine as will control and accelerate the turning movement of the tongue truck through the swinging movement of the guiding tongue, in such manner as to enable the machine to be readily turned and placed in the desired position through the mere turning of the team or tractor in the required direction, and which may be effected without danger of fouling the team with the reel of the machine as is frequently the case in making such turns with machines as now constructed.

rThe above objects are attained by the employment of the construction and arrangement of parts, the preferred embodiment o-f which is illustrated in the accompanying drawings, in which,

Figure 1 is a diagrammatic plan view of a portion of a binding machine, showing the tongue truck as equipped with my improved turning attachment, and indicating by dotted lines the action of the device in turning the tongue truck by the movement of the team to eect the turning of the machine. Fig. 2 is a plan view of a portion of a. binding machine showing the tongue truck and turning attachment thereon in the operated position for effecting the turning of the machine. Fig. 3 is a central vertical fragmentary section through the tractive tongue, the tongue truck and the guiding tongue. Fig. 4 1s a transverse fragmentary sectional view through the parts on line 4 4 of Fig. 3. Fig. 5 is a side elevation of a portion of a binding machine showing the tongue truck equipped with the improved turning attachment, in which one of the tongue truck wheels is omitted to better show the attachment of the parts. Fig. 6 is a fragmentary perspective view of the tongue truck turning attachment as applied to the tractive tongue, tongue truck and guiding tongue of the machine, the parts being in their normal position. Fig. 7 is a perspective view of a yoked fitting for pivotally connecting the tongue truck with the guiding tongue.

Referring to the drawings by the characters of reference marked thereon, 1 represents the plat form frame, 2 the cutter bar, 3 the grain wheel and 4 the main driving wheel of an ordinary binding machine, to the frame 1 of which the usual stub or tractive tongue 5 is pivotally attached at 6.

The usual tongue truck, comprising fianged wheels 7 journaled upon'the ends of an axle 8, which is pivotally connected to a vertical stem 9, is mounted to support the outer end of the tractive tongue 5 by means of a forked fitting 10 secured to the end of said tongue, and which receives and forms a vertical journal bearing for the upper end of the stem 9. Secured rigidly to the stem 9 and lying within the forked fitting 10 is a forked fitting 11 to which the guiding tongue 12 is ordinarily pivotally attached to swing vertically thereon and to impart a horizontal swinging movement to the tongue truck, but in the present instance a yoked fitting 18 is interposed between the end of the guiding tongue 12 and the fitting 11 and is provided with ears 14 to which fitting it is attached by means of a pin or bolt l5 passing therethrough and through the fork of said fitting 11. The end of the tongue 12 is pivotally attached to the fitting 13 to swing horizontally thereon by means of a pin or bolt 16 and is embraced by the odset yoke 17 of said fitting which normally engages with said tongue upon one side to maintain it in alinement with the tractive tongue 5, and is adapted to engage and limit the movement of said tongue at its opposite side at an angle of approximately 4:5 degrees to the planeof the tractive tongue (See Figs. 2, 3 and 4).

The Whittle-trees 18 to which the horses for drawing the binding machine are attached are carried upon the upper end of the stem 9 of the tongue truck, or may be mounted in any suitable manner upon the end of the tractive tongue 5. All of the features thus far recited with the exception of the yoke fitting 13 are commonly employed in the construction of binding machines and form no part of the present invention.

rlrhe novel features of the invention comprise the following described attachments by means of which the turning of the tongue truck is accelerated and controlled by the movement of the tongue and the turning of the machine is facilitated. The axle 3 of the tongue truck is provided with an angu` lar arm 19 which may be rigidlysecured to said axle in any suitable manner, but in the present instance is secured thereto by means of a clamp Vplate 20 through which and the the end of said arm bolts 21 are passed and receive nuts 22 by which the parts are drawn firmly together upon said axle. Said arm 19 extends rearwardly and outwardly from said axle and terminates in an up wardly extending end portion 23. (See Figs. 2, 5 and 6). Extending laterally from the tractive tongue 5 are brace arms 24: which are secured at their inner ends upon opposite sides of the tongueV 5 by bolts 25 or other suitable means, and at their outer ends are connected together and to one end of a brace rod 26by means of a bolt or Cotter pin 27. r1`he opposite end of the brace rod 26 is bolted or otherwise suitably secured to the tractive tongue Secured to the guiding tongue 12 at a point in advance of its pivotal connection with the tongue truck is a pulley 28 carried in a block 29 which is pivotally attached to said tongue by means of a bolt or staple 30. Rove about said pulley is a none-elastic flexible member31, preferably a cable or chain,` one end of which is suitably attached to the pin 27 of the brace arms 24:, and the opposite end of said chain is suitably secured at 32 to the upturned end 23 of the arm 19 ofV the tongue truck. The length of the chain 31 is such as to normally retain the guiding tongue in alinement with the tra'ctive tongue and te position the axle of the tongue truck at right-angles thereto. 1n this position the guiding tongue, lying incontact with one side of the yoke 17 of the fitting 13, steadies the tongue truck against a swinging movement in one direction toward the guiding tongue, while a swinging movement of the tongue truck in theopposite direction is retarded by means of a spring tensicned steady rod 33, one end of which passes freely through an aperture 34 in the end 23 of the arm 19 and is provided at its opposite end with an eye 35 for the reception of a bolt 3G, by means of which it is pivotally attached to the guiding tongue 12 at a point in advance of the pivotal connection of said tongue with the tongue truck. A compression coil spring 37 cmbracing said rod is interposed between the end 23 of the arm 19 and a collar 33 adjustably secured to said rod by means of a set screw 39. (See Figs. 5 and 6.) It will be observed that by this arrangement the tension of the spring 37 will be exerted through the rod 33 upon the tongue 12, and upon the tongue truck at one side of its pivotal axis through its engagement with the arm 19 of the axle of said truck, whereby the tongue will be yieldably held in contact with one side of the yoke 17 to prevent a forward swinging movement of the truck wheel upon the corresponding side of the truck. rlhe truck wheel upon the opposite side will be likewise yieldably retarded against a forward suf'inging movement in a manner to obviate any undue wabbling movement of the truck that might be occasioned by a variation in the resistance against the wheels in traveling forward, while the sliding movement of the steady rod through the truck arm 19 against the tension of the spring 37 permits said truck to swing at a greater ratio of movement than the movement of the guiding tongue 12 as motion is imparted thereto through the chain driving connection, as clearly illustrated in Fig. 2.

The steps in the operation of the device in turning the machine are best illustrated in the diagrammatic view of Fig. 1, in which the machine is shown in position to be turned so as to present the cutter bar to the grain (as indicated at 10) at right-angles to the preceding eut, in completing which out the cutter bar of the machine is stopped slightly in advance of the standing grain. The team indicated at L11 is then swung to the left, to the position indicated by dotted lines 412. 1n making this movement the guiding tongue 12 in swinging about the axis of the tongue truck draws bodily upon the chain 31, which, being anchored at one end to the brace arm 24 of the tractive tongue, is caused to pay out upon that side in passing through the pulley block 29 of the guiding tongue 12, and to take up on the side attached to the arm 19 of the tongue truck, thus drawing upon said arm and tongue and imparting an accelerated swinging movement to the tongue truck with relation to the movement of the guiding lll) tongue, which augmented movement is permitted by the sliding of the steady rod 33 through the arm 19 against the spring 37 and the pivotal connection of said tongue with the tongue truck. The relative arrangement of the parts is such that when the tongue shall have reached a position approximately at an angle of 45 degrees to the tractive tongue the axle of the tongue truck will have swung degrees, or to a position in alinement with said tractive tongue, as shown in Figs. l and 2. In this position the wheels of the tongue truck are so set as to travel in the arc of a circle of which the main wheel 4 of the machine forms the axis, and by the further forward angular movement of the team to the position indicated at 43 the machine will swing upon the pivot formed by the main wheel 4 so as to carry the grain wheel 3 in the arc of a circle about said main wheel and present the cutter bar 2 at an angle of approximately 45 degrees to theA line of the standing grain40. The angle of the tongue truck in this position of the machine will have swung out of alinement with the tractive tongue to a position so as to travel in the arc of a circle with the main wheel 4, and through the further forward angular movement of the team toward the grain the machine will be swung upon a pivot formed by the grain wheel and the cutter bar of the machine will be presented to the grain, as indicated by the dotted position 44, in position to cut a full swath at right-angles to the preceding cut when the tongue truck will have assumed its normal position as indicated by dotted lines at 45. In this position the tongue truck is steadied against a wabbling movement by the engagement of the yoke with the guiding tongue upon one side and the tension of the coil spring of the steady rod engaging the tongue and arm of the truck upon the opposite side.

t will be apparent that by the employment of the foregoing construction and arrangement of parts in connection with binding machines, that the turning of the machine at the corners of the standing grain may be readily effected by the simple operation of turning the team or tractor in a forward angular direction at the completion of each cut, and that the loss of time incident to the necessity for backing up and maneuvering with the team to effect the turning of the machine as is common is avoided, thereby saving materially in the waste of' energy and time in harvesting the grain.

It should be understood that the application of this device is not limited to the particular type of tongue truck illustrated herein, but may be applied with equal efficiency to various types of machines as now in common use, in which it may require some variation in the size, shape and manner of attachment of the parts but which will not involve a material departure in the general plan, arrangement and cooperative relations of the essential elements disclosed herein and comprised in the appended claims.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is:

l. In combination with a binding machine having a tongue truck pivoted to swing thereon, a fixed support on said machine, a tongue pivoted to swing on said tongue truck, power transmitting means connecting said fixed support with said tongue y truck and said tongue, whereby through a swinging movement of said tongue movement is transmitted to swing the truck and accelerate the movement of said truck, and means connecting said tongue with said truck for yieldably retaining said truck and tongue against relative movement.
