WIRE BINDER.

SPECIFICATION forming part of Letters Patent No. 646,819, dated April 3, 1900. Applicationled March 17, 1899. Serial No. 709,484. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE D. FOSTER, of Preston, in thecounty of Jackson and State of Iowa, have invented certain new and useful Improvements in Wire Binders, of which the following is a specification.

This invention relates to improvements in Wire binders, and refers more speciicallyto a mechanism particularly adapted for binding bales or bundles.

Among the objects of the invention are to provide an apparatus of extremely simple, strong, and durable construction whichmay be manually operated to form a simple and effective band or bale from a continuous length of wire, an apparatus which may be readily applied to most bundling and baling machines, and to provide improvementsl in the details of construction of an apparatus embodying my invention especially adapted for binding corn-shocks.

The invention consists in the matters hereinafterA described, and more particularlypointed out in the appended claims, and the same will be readily understood, reference accompanying drawings, in which Figure 1 is a plan view of an apparatusembodying my invention mounted upon the yoke of a corn-shock-compressing machine. Fig. 2 is a side elevation, with parts in section, of the same apparatus. Fig. Slis a fragmentary detail of parts shown inFig. 2 on an enlarged scale. Fig. 4 shows the form of one of the bands or bales in its finished condition. Fig. 5 is a detail perspective view of the wire clamp whereby the free end ofl the wire is held during the knotting process. Fig. 6 is a side view of the combined guide-pulley and tension device whereby the end of the wire is held after a finished band has been severed therefrom. Fig. 7 is an enlarged side elevation of the rotary knotter and gear which drives the same, including the crank and spring-latch, whereby the gear is operated and controlled. Fig. 8 is a top plan view of the parts shown in Fig. 7, showing the knotted portion of a band in position in the mechanism by which it is formed. Fig. 9 is a detail side elevation of one of the guide-plates which supports the knotter. Fig. 10 is a detail side elevation of the wire-severing device.

The invention is shown in the present instance as embodied in the form of a cornshock binder, to which purpose the details shown herein are particularly adapted; but it is to be understood that the general features of the invention are applicable to various other analogous purposes. 4

Referring to the drawings, A designates as a whole the V-shaped yoke or frame of a shock-compressing apparatus-such, for example,as that shown in Letters Patent granted to me,No. 562,177, dated June 16, 1896. Upon the cross-bar ct of said yoke, against which the shock or bundle of shocks is compressed, are mounted in parallel relation two upright supporting-plates B, (see detail Fig. 9,) having upon their proximate faces annular grooves b. Between the said supportingplates is mounted a pinion (hereinafter termed the knotter) C, having in its side faces annular ribs or flanges c,which engage the grooves b of the supporting-plates and hold the knotter in position, while 'permitting it to rotate freely.

The knotter is provided at one side with a radially-arranged slot or openin g c', which eX- tends from the periphery inwardly approximately to the center of the knotter. Within this slot and arranged so as to divide the same is a radially-extending lug or finger c?, the

permit the placing of the wires within the knotter in this manner and in order not to interfere with the wires during the pressing together of the latter the side supportingplates B are made approximately L-shaped in side elevation, so as to leave the central portion of the knotter and approximately one segmental quarter of it unobstructed.

IOO

In order to rotate the knotter to twist the lapped ends of the band together, a shaft E is mounted in suitable bearings c upon the frame A, and upon this shaft is fixed a driving-gear E', arranged to intermesh with the teeth of the knotter. Preferably the gear E will be of such size as to rotate the knottera given number of complete revolutions during a single revolution of the gear, (four times in the present instance,) so that the position of the knotter at the end of a complete revolution of the driving-gear will always be the same, for a purpose which will hereinafter appear.

E2 designates a crank secured upon the end of the shaft E, and E3 designates a springlatch mounted upon a suitable support a, so as to extend alongside of the path of the crank E2and provided with two shoulders e' e2, which serve to arrest the movement of the crank in one direction or the other. The free end of the spring-latch is provided with a fingerhold c3, whereby the latch may be defiected o1` bent sufficiently to allow the crank to pass freely in either direction when desired.

G designates a reel or spool of wire rotatably mounted upon the frame A, the shaft of the reel being provided with a crank-handle, whereby it may be turned to draw the wire taut after adjustment around the bundle and before the knot is formed. From the reel the wire is led underneath a guide-pulley g and thence through a tension device H, which also serves as a guide-pulley, and is located upon the frame A in a position approximately in alinement with the axis of rotation of the knotter. The tension device consists in the present instance of a grooved pulley 71 mounted upon a suitable bearing 7L', and a frictionpulley h2, mounted upon a spring-pressed shaft hB and arranged to bear yieldingly against the pulley h, the wire being trained between the two, as shown clearly in detail Fig. G.

From the tension device the wire passes through a cutter I, consisting in the present instance 'of an upright blade t', mounted in a suitable casting I', with which coperates a pivoted pressure-bar I2, pivotally mounted at its lower end, as at '15', adjacent to the blade 1T, and provided at its upper end with a handle t2, whereby it may be oscillated to force the wire against the edge of the blade to sever the same. The pressure-bar is desirably held in upright position, so as to serve in connection with the blade to form a guide through which the wire passes, by means of a stop i3. After passing through the knotter the free end of the wire is secured in a clamping device J, which, as herein shown and as conveniently` made, consists of a pair of parallel curved fingers j, rigidly mounted upon the frame A, and a clamping-jaw j?, having its acting face made convex to correspond to the curvature of the fingers and mounted upon a shaft ji, working through a bearingjt, so as to be capable of being projected between the fingers. The clamping-jaw is conveniently operated by means of a horizontal lever K, connected at one end with the lower end of the shaft f and pivotally mounted at a point and the end secured in the clamp J.

intermediate of its length, as at j", Fig. 8, upon the frame member a, the other end of the lever being arranged to project through a loop j upon the end of linkj7. The link is connected at its opposite end with an armjs, rigidly connected with the presser-bar I2 in such manner that when the latter is oscillated forwardly to cut the wire the clamp will be opened, and, vice versa, when oscillated in the opposite direction the clamp will be closed.

The operation of the apparatus, constructed as described, is as follows: A shock or bundle of stalks having been brought within the yoke and suitably compressed, the end of the wire is carried from the tension device across over the knotter in rear of the bundle, around the latter, and across over the knotter aglailn e knotter being in the position shown in Fig. 7, the overlapped ends are adjusted within the knotter at opposite sides of the lug c2 of the latter, the reel turned so as to draw the wire taut, and the crank E2 of the drivinggear turned a single revolution to the right or in the direction indicated by the arrow in Fig. 7, permitting the shoulder e' of the spring-latch to arrest the .movement of the crank. This single revolution of the driving-gear will complete the twisting together of the wires in t-he form shown in Fig. 8, and when the crank-handle F.2 is in position resting against the shoulder e the opening and lug c2 of the knotter will be directed horizontally forward or toward the bundle, so that the latter may be disengaged from the knotter without difficulty. Y The band is thus completed, and it only remains to sever the wire by means of the cutter I. As the presser-bar is oscillated to cut the wire the clamp will be opened to release the opposite end and the bundle thus freed ready to be discharged. Before beginning to bind the next shock or bundle the crank of the driving-gear will be shifted back from the shoulder e to the shoulder e2 of the spring-latch, thus restoring the slot of the knotter to a vertical position to more conveniently receive the wire.

While I have herein described and illustrated what I deem to be a preferred embodiment of my invention, yet I do not wish to be understood as limiting myself to the precise details of construction shown except as made the subject of specific claims.
