MACHINE FOR FORMING HOOKS ON WIRE BALE-TIES.

SPECIFIGATION forming part of Letters Patent No. 748,580, dated January 5, 1904.

Application filed April 21,1903.

To all whom it may concern:

Be it known that I, BRUNO VON BiiL'rzING- SL6WEN,a subject of the Emperorof Germany, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Machines for Forming Hooks on Wire Bale-Ties, of which the following is a specification. I 1

These improvements relate to the same type of machines as described in my application, Serial No. 103,199, filed April 16, 1902, and are fully described in the following speci-' fication with reference to the accompanying drawings.

The main object of my present invention is to improve my aforesaid previous construction, so as to simplify and facilitate the different movements-that is to say, to provide means for automatically bending the wirethereby facilitating the work formerly performed by the operator and for strictly confining the wire in place before and during the bending operation, so as to allow bending of even the strongest wire used in binding haybales.

Another important feature of my improved construction is the use of a coupling device which can be thrown into engagement by the least possible power and which results in a tight hold of the coupled shafts, nevertheless allowing an easy and automatioal disengagement of the same.

In the accompanying drawings, Figure 1 is a plan view of a machine embodying the afore-' said improvements. Fig. 2 is a plan view of the same, taken from underneath the baseplate. Fig. 3 is a front elevation of the ma chine, the base-plate being cut away, so as to expose all parts below the same. Figs. 4 and 5 are cross-sections on line 4 4 and 5 5, respectively, of Fig. 3. Fig. 6 is a detail front view of the principal parts of the hook-bending mechanism in inoperative position prior to the bending operation. Fig. 7 is a similar view showing the position of the parts at the completion of the bending operation, the bent wire being in place. Fig. 8 is ,a detail end view of the hook-bending mechanism. Fig. 9 is a detail cross-section of the same. Fig.

ing the twisting operation, the wire ends being shown in section and'all parts in their operative position. Fig. 11 is a detail plan view of the clamp device. Fig. 12 is a detail longitudinal section of the new coupling device. Figs. 13 and 14 are respectively a detail front view and plan view of the lever for bending the free end of the wire toward the long end of the wire body. Figs. 15 and 16 are respectively a detail front view and a plan view of the cam projection effecting the retn rn movement of the main lever for the operation of the hook-bending mechanism, and Fig. 17 is a side View of a hook bent on my improved 7 machine.

Similar letters of reference indicate corresponding parts throughout the drawings.

A represents the base-plate, supported so as to allow arrangement of mechanisms above and below the same. A rocking lever K is pivoted to a bracket or upon the base-plate, embracing with its upper forked end a sliding sleeve B upon the main shaft 0, the latter being journaled in bearings A and A upwardly projecting from the base-plate A. The forked end of lever K carries frictionrolls h in engagement with the projecting side flanges of sliding ring B, which is fastened to its shaft by spline connection. At the left-hand flange of the sliding ring B, Fig. 3, three pivot-carrying ears I) are provided, which by means of links df f serve for operating the hook-bending mechanism; The latter comprises the following parts: A circular head 0 on the main shaft 0, having lateral recesses cto receive two of the ears I) of sliding sleeve 13. A flattened head portion cast integrally with the forwardlyprojecting plate E, on which the hook-bend ing mechanism is mounted, is screwed onto the circular head 0. A wire-bending lever E bent at a certain angle, so as to correspond with the shape of the hook, is laterally secured to arm E, which is fastened upon a pivot e journaled in the plate E. A pin e projects eccentrically from the forward end of the pivot 6 while a pinion-E meshing with another pinion E, is keyed on the opposite end of the same. The pinion E is rotated by the sliding sleeve B through the medium of link f and. crank f. The hookbending lever F turns loosely upona studf,

projecting from the lower part of the plate E,

and forces wire 2 round a pin 6. A cam-surface f of lever F operates a third lever E also pivoted to the plate E, against the tension of a leaf-spring 6 The left-hand upper end of lever F, Fig. 7, is provided with an upwardly-projecting support f for lifting up the long end of the wire body z and securing both ends of the bent hook in proper position for the clamp device, which will be described later on. A link f connects lever F with the sliding ring B.

The mechanism for tightly holding the bent hook in its position while the ends thereof are twisted around each other consists of a lock-plate D, sliding with its lower cut-out portion in acorrespondingly-formed plate D, which is screwed upon the plate E. A coverplate D is fastened on plate D,.overlapping the aforesaid cut-out portion, thus resulting in a tight hold of plate D, which may be shifted by the sliding sleeve B through link (1. At the end of the plate E a spring-sup- "ported lock e is provided, which keeps the long end of the wire body in a straight line during the operation of the hook-bending lever F. This look a is acted upon by a lateral projection e of the wire-bending lever E against the tension of a leaf-spring e The clamp device for tightly gripping the wire ends during the twisting operationconsists of a bracket A screwed upon the baseplate A, and a support-plate G, laterally projecting therefrom. The upper end of the bracket A at its inner face possesses a die g, which forms in connection with a similardie g on a rocking clamp-lever G a proper support for the wire ends 2. This rocking clamplever G is pivoted to plate G and acted upon by a roller g journaled at the outer end of an oscillating double lever Gr, also pivoted upon plate G. A spring 9 draws the rocking lever Gr back to its normal position. The oscillating lever G is turned upon its pivot, so as to act upon or release the clamp-lever G by means of a rod G sliding vertically upon its longitudinal recess g, and an angular connecting-link G The rod G3 projects through a suitable opening of base-plate A and carries at its lower end a lateral projection g. The support-plate G has at its upper edge a groove 9 as guiding means for correctly inserting the wires 2, this groove g being in a vertical plane with the dies g g when they are in their operative position.

The means for automatically operating the hook-bending mechanism consists of the following parts: A bearing V is screwed underneath the base-plate A, carrying shaft S, to

c the forward end of which a disk N is fastened, being provided with several projections and cam-surfaces. .A semicircular plate N, integrally cast with this disk N, lies in its inoperative position with its diametrical edge against the main lever K for operating the A bracket 0, se-

cured underneath the base-plate A, has laterally-projecting guide-rails 0, undercut, so as to tightly secure and guide a rod M, one end of which carrying a friction-roller m, lying against the main lever K, while to the other end an upwardly-projecting arm m is laterallysecured. The outer end 72 of an abutment n rests just below this arm m before the machine is started. Another semicircular cam N is provided upon the periphery of disk N in such position as to operate the clamp device for securing the wire ends 2 during the twisting operation.

L'indicates a bracket downwardly projecting from the base-plate A. Pivoted to the bracket are an angle-lever L and a double lever L connected by means of a link L and carrying at their free ends friction-rollersl and Z, respectively.

The roll Zrests upon the lateral projection g of the vertical rod G and depresses the latter against the tension of a spring g when friction-roller Z is depressed by and running upon the cam N The means for starting the machine comprise a foot-lever (not shown in the drawings) acting upon an angle-lever V which is fulcrumed at a bracket V, downwardly projecting from bearing V, and a coupling device of a simple yet very efficient construction. A cylindrical casing S is mounted upon shaft S by a spline connection 3 This casing S has a cut-out portion 8, so as to allow insertion of a spiral spring 8 surrounding shaft S, while the inner end of this spring is supported at the end of boring s. The movement of the spring in the opposite direction is limited by aring S secured on shaft S. The flange S of the casing S has outwardlyprojecting coupling-fingers s,which are in position to engage corresponding projections s of bevel-gear P, loosely mounted on the rear end of shaft S. The left-hand flange of the casing S, Fig. 4, has a boring for a pin v, secured at the rear face of bearing V, thereby limiting the rotation of coupling S to just one revolution. The bevel-gear P meshes with a smaller gear P, secured on one end of a shaft U, which is journaled in a bearing U under the base-plate A. The other end of this shaft carries a chain-wheel U which is operated by means of a chain and another chain-wheel I from the main shaft 0. The chain-wheel I is secured upon the hub of a driving pulley I, which is loosely mounted upon shaft 0, the same coupling, as above described, being used for throwing this pulley into engagement with its shaft. The cylindrical casing H is mounted upon shaft 0 by a spline connection h. A spiral spring 72?, which is placed in the cut-out portion h, is limited in its movements by a ring H tightly secured upon shaft 0. Coupling-fingers h are provided at the end flange H so as to engage corresponding coupling-fingers h, laterally projecting from the pulley I. The opposite end flange H is acted upon by IIO , ima e a rocking lever K, whichthrows the coupgle-lever R, which rocks lever K by means bearing A of a friction-roller R thereby throwing the coupling on the main shaft into engagement. At the same time a pin 7c, laterally projecting from lever K into a boring of a disk T,

mounted upon an axle T, releases said disk,

which starts to rotate on accountof its connection with the main shaft 0.

O and T represent chain-wheels in a ratio of one to three,thereby allowing three revolutions on the main shaft 0 during one revolution of axle T, the latter being mounted in bearings A A underneath the base-plate A. A bracket R, to which the angle-lever R is pivoted, projects downwardly from the bearing A, while the rod t is screwed into the A spring 10 connects said rod t with the lower end of lever K.

The operation of the machine is as follows: The pulley I may be operated by any suitable power whereby by means of the chainwheel connection I U operation is transmitted to the bevel-gear P. On depressing the foot-lever, which is not shown in the drawings, this bevel-gear P is thrown into engagement with its axle S; but on account of the pin 0 and its corresponding recess in the coupling S the operation will be limited to one revolution only. The Wire ,2, which is placed in the machine in a position indicated in Figs. 3 and 6, is bent through the rotation of disk N. The moment the machine starts the cam N actuates the main lever K, the lower part of which is pushed to the right to a position indicated in dotted lines in Fig. l

3. During this progress the hook is bent and tightly kept in its position by lock-plate D. The heel f of the hook-bending lever F has lifted the long end of the wire body so far as to bring it in close contact with the short end of the bent wire, thereby placing both in 'a proper position for the gripping device, which by means of the actuating-cam N operates immediately after the hook is bent. While the hook-bending lever F performs its operation, the spring-supported lock 6 serves as abutment to keep the long end of the wire body in a straight horizontal line. This lock is, however, removed from the path of the bending-lever E by the projection e of the latter shifting the lock e back against the tension of its leaf-spring e so as to allow the wire to pass. As soon as the wire ends are tightly secured in the recess 9 g the lever K is turned upon its pivot by means of the lateral abutment n of disk N, passing angle-lever R and forcing the same into the dotted-line position of Fig. 3. The upper end of the lever K throws thereby the coupling H into engagement with the driving-pulley I, and as at the same time the pivot 7r has released disk'T the latter starts to rotate in the ratio of the chainwheels (J and T After the-abutment 'n has passed angle-lever R lever Kis kept in its position by pin it sliding on the side of disk T until one revolution of the same is completed, when, following the tension of spring lever K locks disk T and disengages the coupling H of the driving-pulley I. At the same time guide-rod M is horizontally shifted through the medium of the abutment n n striking the upwardlyprojecting arm m. The friction-roller m at the other end of the guide-rod M thereby draws back the main lever K to, its normal position, whereby the finished hook is exposed, so as to be easily removed, the clamp device having retion-roller Z of the oscillating lever L has slipped from the actuatingcam N and under the tension of spring g all parts have returned to their inoperative position. At the same time the automatical coupling S is thrown out of engagement with the revolving bevel-gear P after one complete revolution, as pin 12 enters the boring in the side flange of the casing S.
