UNITED STATES PATENT OFFICE.

CALVIN YOUNG, OF AUBURN, ASSIGNOR OF ONE-HALF TO D. M OSBORNE & COMPANY, OF NEW YORK, N. Y.

GRAIN-BINDING MACHINE.

To all whom it may concern.- Be it known that I, CALVIN YOUNG, of Auburn, in the county of Cayuga and State of New Yorlqhave invented certain improves 'mengl in Grain-Binding Machines, of which the to lowing is a specification. The present invention has reference more particularly to what are known in the art as Appleby binders, represented'in their lead- 1 ing features in Letters Patent of the United States, No. 212,420.

The invention relates to various improvements in the details of the machines, whereby they are rendered more satisfactory in operation.

The improvements consist, principally, in a slack-arm of peculiar arrangement for the purpose of controlling the tension of the cord or other binding material; in an improved arrangement of mechanism for operating the cord-clamping disk, and in an improved construction and arrangement of the compressorarm, against which the compression of the gavel is efiected, and by which the machine is 2 5 automatically tripped into action through the pressure of the grain.

Referring to the accompanying drawings,

Figure 1 represents a vertical section through an Appleby binder having my improvements 3o embodied therein, the section being taken in a plane parallel with the binder-arm. Fig. 2

is a perspective view, illustrating the arrangement of the slack-arm. Fig. 3 is a side elevation, showing the cord-tying and clamping 3 5 mechanism and the attendant parts. Fig. 3 is a side elevation of the compressor-arm and its supporting-link. Fig. 3* is an end elevation of the same. Fig. 4 is a top plan view of the cord-clamping disk and the parts operating in 0 immediate connection therewith. Fig. 5 is a top plan view of the jaw or clamp used in connection with the clamping-disk. Fig. 6 is an edge view of the devices represented in Fig. 4,with the clamp or jaw in position. Fig. 7 is 5 a top plan view of the cord-placing and knifecarrying arm. Fig. 8 is an end view of the same, looking in the direction indicated by the arrow in Fig. 7 Fig. 8, a like view, with the rear arm broken away to give a clearer View of the guiding-surfaces. Fig. 9 is a front ele- SPECIFICATION forming part at Letters Patent .No. 382,203, dated May 1, 1888.

vationof the binding-machine, illustrating the driving-gear. Fig. 10 is a top plan view, illustrating the cam and gearing for operating the knotter andcordclamping devices.

, Referring to the drawings, A represents the inclined binding-table upon. which the loose grain is delivered; B, the vibratory needle or bindingarm arranged to ascend through the table and pass the cord around the gavel to the tyer; O, the circulatory packers, by means of which the grain is forced downward to form the gavel; D, the upright compressor, located at the lower edge of the binding-table, for the purpose of assisting in the compression of the grain and of throwing the binder-driving mechanism into action when the gavel has received the required degree of compression; E, the stationary breast-plate, located above the binding-table for the purpose of confining the grain from above and assisting in its compression; F, the rotary tying-bill; G, the vibratory cord-guiding and knifecarrying arm; H, the cord-clamping disk; I, the verticallyswinging frame by which said disk is supported and carried; J, the rotary main shaft, from which motion is imparted through intermediate mechanism to the tying, clamping, and cutting devices; and K, one of the rotary ejector-arms carried by the .shaft J, for the purpose of removing the bound bundles from the machine.

The above parts are constructed and ar-.

down in a natural position during the accu mulation of the gavel, after which the device strains the cord and increases its tension during the tying operation. This slack-arm is clearly represented at L in Figs.1 and2. At its lower end it is mounted on a crank, M, se-

IOO

cured to and. extending downward from the shaft N of the binder arm or needle, so that as the arm ascends to encircle the gavel with twine the crank M is caused to move the slackarm inward or backward. At its upper end the slack-arm slides through a guide, a, and is provided with an eye, a, through which the cord passes in its course to the needle. This end of the slack-arm is located between two fixed guides or eyes, I), through which the cord also passes, so that the slack-arm, being moved backward during the ascent of the needle, bends the cord backward between the guides b, thereby causing additional cord to bedrawn from the ball or spool, and at the same time straining or increasing the tension of the cord, so as to apply the greatest strain thereto during the time that the tying device is forming theknot. After the binding of each bundle has been completed the needle descends, during which action the crank M is restored to its original position and the slack-arm drawn downward or forward, bringing its eye a again into line with the-guides b, the effect of which is toslacken or loosen the cord and permit the surplus portion, which was drawn from the spool by the backward movement of the slackarm, to pass freely downward beneath the action of the loose grain delivered upon the binding table. Thus it will beseen that by means of the arm L the cord is tightened upon the bundle and an additional supply drawn from the spool during the binding action, and that, on the other hand, during the accumulation of the gavel, while the loose grain is flow ing inward, the cord is slackened and permitted to pass freely to the gavel.

Passing now to the cord-clamping disk and its operating devices, which constitute the second feature of the invention, attention is particularly directed to Figs. 1, 3, 4., 5, and 6. I The (damping disk H, notched in the Y periphery to admit the cord, isjournaled centrally upon the vertically-swinging frame I, hinged, below the main shaft, this arrangement permitting the lower end of the frame, withthe disk thereon, to rise and approach the tying-bill F during the formation of the knot, for the purpose of slackeningthe cord thereto, as in other, machines of the present day. The

ing jaw or clamp, N, grooved to receive one edge of the disk, asjusual. For the purpose of impartingthe necessary intermitting rotation to the clamping-disk, it is provided, as shown in Fig.4, on the'under side with a series of ratchet-teeth, d, acted upon by a pawl or dog, e, mounted on a swinging arm, j, which is journaled upon the supporting-frame I, concentric with'the disk. The dog 6 is acted upon at its rear end by a spring, 9, securedtothe arm, whereby it is caused to engage with the ratchet-teeth during its forward motement. The vibrati'onof the pawl-carrying arm f is effected by means of a rod, h, one

end o which isjointedto said arm, while the opposite end is connected, as shown in Fig'srl fixed stud, 1", cast on the frame.

and 3, to a lever, i, this lever being in turn connected at its upper end by a pivot, 75, to the main standard or frame of the machine. The lever t receives a vibratory motion through a roller, Z, mounted upon its middle and arranged to enter a cam-groove, m, formed in the. side face ofa disk, 0, secured upon the main shaft J, as represented in Fig. 1, the groove at being 'of such form as to operate the lever i when the disk is to be turned, and to hold the same at rest during the intervening periods. The diskoperating rod h is preferably connected to the lever 2' through the medium of a head or end piece, 0', screwed upon the end of the rod and secured by a jam-nut, as shown in Fig. 3, this construction permitting the position ofthe pawl-operating lever with respect tothel'ever z to be adjusted as may be required in order to turn. and stop the disk at the exact points demanded. Y The backward rotation ofthe disk during the retrograde movement of the dlitb.

ing-pawl e is prevented by means of a piTWhp, pivoted upon the frame I, and actuated by a spring, (1, one end of which is riveted'to the pawl, while the opposite end bears against a This pawl p swings upon the same pivot which supports the cord-clamping aw of the plate N. The jaw N is urged against the disk by means of an upright spring, 8, thelower end of which is bolted to an arm depending from the frame I.

The disksupporting frame I is depressed,- but permitted to rise at the proper time by means ofan eccentric or cam,P, mounted on the main shaft, as shown in Figs. 3 and 10, and arranged to bear upon a roller, Q, journaled in the frame I. The downward-swinging motion of the disk-carrying frame I is limited by means of a vertically-adjustable suspensionhook, S, the stem of which is threaded and passed through the main standard and secured by nuts t above and below the same, as shown in Fig. 3. The book engages beneath the pivot or journal of the rollerQ. By adjusting the nuts the descent of the frame and clampingdisk may be arrested at any desired 'point.

While it is preferred to retain thehook S as the most simple means oflimiting the motion of the parts, any equivalent form ofsuspension device may be employed,

Passing next to the cord-placing and knifecarrying arm, attention is directed to Figs. 1,

3, 7, and 8. v The arm, pivoted near its upper end *tothe main standard, and vibrated by means of a cam-groove in the face of the main wheel T, has its lower end notched and arranged to vibrate past the end of the rotary tyer, substantially as in former machines. In-

stead, however, of giving the end of this arm the usual V form to receive the cord, I construct the same in the peculiar form represented in Figs. 7 and 8, with a central cordreceiving opening, a, and with two inclined surfaces, o and w, standing at substantially right angles to each other and communicating with the opening to bya narrow slot or passage, as. The faces '0 and w are inclined on opposite IZO- WW M

sides of the perpendicular and on opposite sides of the slot at, so that when the cord is laid in position by the needle the surfaces oand u; will serve to guide the same in a positive manner to the slot as, and thus insure its passage downward into the opening a, where it is securely confined in such position that the proper action of the tying bill thereon is secured.

Referring next to the construct-ion and arrangement of the compressor D, reference is made to Figs. 1 and 3. The upright arm or compressor proper, a, against which the grain acts, is secured at its base by means of a bolt upon the upper. surface of a plate, 1), upon which it may be adjusted lengthwise, in order to produce an increased or diminished grainspace between the compressor and binder-arm, and thus vary the size of the bundles. The plate I) is pivoted at 0' to the side of a vertically-vibrating arm, d, its motion being limited by a stud or pin, 6, passing through a slot therein, as shown, this arrangement permitting the plate b and the compressor proper to be tipped backward to trip the driving mechanism into action in a manner which will be hereinafter explained. The arm d is pivoted at its forward end, f, to the hub of the needle, and is moved vertically at the proper times in order to maintain the elevation of the compressor above the table during the binding operation and to depress the same below the table when the bundle is to be discharged.

The'vertical motion of the compressor-earrying arm d may be efiected by means of a link, 9', connecting with a rock-shaft, h, in the same manner that the compressor-arms of the ordinary machines are operated, or by any other equivalent actuating mechanism. The swinging plate b is provided with an ear, is, connected by a chain or other device, Z, to the .nsual rock-shaft, an, by which the driving mechanism is tripped into action. During, the binding of the bundle the arm 01' remains fixed in position, with the compressor standing above the table to sustain the grain. WVhen the pressure of the grain against the compressor exceeds the predetermined limit, the arm a and plate I) swing backward together around the pivot c, the arm d remaining for the time being unmoved, the result being, through the intermediate devices, to set the binderin action. After the completion of the binding operation the arm (1 is permitted to swing downward, thereby lowering the arm a below the table and discharging the bundle, subsequent to which the parts resume their original positions, as usual in this class of machines.

The present invention is restricted to those matters and things which are hereinafter claimed.

It is to be noted that in this machine, as in others of its kind, the position of the cord with respect to the bills of the rotary tyer is determined in part by the clamping-wheel, the rotation of which has the effect of moving the cord laterally; hence it is of the highest importance that the disk shall be turned to and stopped in a particular position. The adjustable connection between the pawl-carrying arm and the vibratory lever through which it receives motion is a valuable feature, since it will compensate for the wear of the operative parts and permit an exact adjustment of the disk, notwithstanding those variations in the form, size, and location of the parts which inevitably occur in the course of manufacture.
