SIDNEY J. ORNSTON, OF NEW YORK, N. Y. i

DEVICE FOR SECURING WIRE BINDERS.

Application filed January 11, 1924. Serial No. 685,515.

To all whom it may concern:

Be it known that I, SIDNEY J. ORNSTON, a citizen of the United States, and a resident of the borough of Bronx, county of Bronx, city and State of New York, have invented certain new and useful Improvements in Devices for Securing Wire Binders, of which the following is a specification sufficient to enable those skilled in the art to which the invention appertains to utilize the same.

lVhile adapted for use in connection with wire binders for various analogous purposes, my improved wire tightening and securing device is designed primarily for tightening and securing wire binders around and upon wooden boxes in a more convenient, expeditions and effective manner than thereto fore,the invention consisting essentially in the specific combination, construction and arrangement of parts and appurtenances described and claimed, whereby these and other advantageous results are attained, and a distinctive feature being the duplex character of the implement whereby both extremities of a binding wire are manipulated simultaneously, all as hereinafter fully set forth. I

In the accompanying drawings I exemplify a practical embodiment of the essential features of my invention, although I do not limit myself to the identical form and construction of component parts shown, since modifications in minor details, and equivalent mechanical expedients may be resorted to with like results and without departing from the spirit and intent of my invention in this respect.

\Vith this understanding Fig. 1, represents a top view of my improved device for securing binding wires:

Fig. 14, is a detail illustrating the actuation of shearing off the superfluous ends of the wire binder;

Fig. 15, is a detail perspective of the twister gear.'

The basic frame work consists of the longitudinal spine member B, having the rear extensions 6', 6 ,6 and 6*, and the frontal extensions 6 b On and between the said rear extensions b, 6 12 is mounted the wire tension power shaft P, on the left hand extremity of which is fulcrumed the hand lever H, carrying the spring pawl k, which engages with the ratchet-wheel 19, rigidly mounted on the said hand power shaft P, p, being a detent pawl pivotally mounted on the outer side of the base extension 79, and engaging peripherally with the said ratchet-wheel p, as'shown more particularly in Fig. 3, of the drawings. Hence reciprocatory movement of the hand lever H, will rotate the shaft P, intermittingly, affording power and actuation to the other operative parts of my binding implement, considering the latter in aunitary sense.

Transmission pin-ionsp p, rigidly attached to the-intermittingly rotatable power shaft P, mesh with the mitre gears g, 9 rigidly attached to the rear ends of the counter shafts g, 9 which latter, are jour nalled in the aforesaid frontal extensions .6 b, of the base B. Rigidly securedto the said ends of these countershafts g, 9 are the twin wire gripping discs G, G formed with the radial face slots 9*, for engagement with the extremities of the binding wire 'w, as shown more particularly in Fig.- t), of the draw ngs the ends said bind ing wires w, being bent and inturned d i agonally against the discs G, G w1th1n the gripping slots 9", g, on opposite sides of the faces of the said twin discs G, G so that the rotation thereof tends to clinch the ends of the wire. In this connection it is to be noted that the transmitting pinions 79 79 are opposed in position with relation to each other, and mesh with opposite sides of their respective mitre gears g 9 so that the countershafts g, 9 and the grip discs G, G will rotate simultaneously in opposite directions when the lever H, is manipulated.

B, B 13 ,13 are bearing brackets bolted to the spine member B, of the base frame.

work, and affording support for the wire twisting, cutting and effective mechanism.

C, is a crank shaft extending through the said bearing brackets B, B B B and journalled in the aforesaid frontal extensions 5 ,19 of the spine member B, of the frame work, said crank 0, being provided at its right hand extremity with a crank handle C, by means of which. the shaft is rotating ,to effect the twisting of the overlapping ends of the binding wire etc. Rigidly mounted on the crank shaft C, is a driving gear 0, positioned in a recess 5", formed between the opposed sides of the brackets B B as shown more particularly in Figs. 4 and 12, of the drawings. Meshing with the driving gear 0, which is intermediate in character is the wire twisting gear t, and the lock gear L, both also positioned in the aforesaid recess 6*, within the brackets B B The twistergear t, is journalled in and between the brackets B B andin the construction and arrangement of parts shown in the drawings its diameter is one half that of the lock gear L, so that it will be rotated twice by the intermediate drive gear 0, to every rotation of the lock gear L thus prescribing thenumber of con volutions to be effected by. the twist. Ijdo not limit myself however in this respect, since it is-obvious that by varying the relative diameters of the twister gear t, and the lock gear L, the number of convolutions imparted to the wire 10, may be increased or diminished according to requirements.

The twister gear 75, is formed with the ra dial slot 6, for the reception of the parallel end strands of the binder wire, the front edges of the bracketsB B, being shaped to afford access to said slot 6, as shown in Fig. 4.

Normally the three gears L, 0, and t, are held against rotation by a spring bolt 8, which engages with a peripheral notch Z, formed'for'the purpose in the hub Z, of the lock gear L, thereby dogging the crank shaft C, through the medium of its intermediate drive gear 0, as willbe understood by reference more particularly to Figs. t and 13 of the drawings.

The lock gear L, is mounted rigidly on a shaft L, which in turn is supported rotatably in bearings formed for the purpose in the brackets B B as shown more par ticularly in Fig. 13, of the drawings, said shaft L, extending laterally on either side beyond the brackets B B and over the brackets B, and B there being held against longitudinal movement by the lock gear L, and its hub Z. Rigidly secured to the lock shaft L, near its outer extremities are thrust cams K, K, against which rest the long arms a, a, of the rock levers A, A, fulcrumed at a, a, in the side walls ofthe recesses formed for the purpose respectively in the brackets B, B, (see particularly Fig. 6,) the short eccentric arms a c of said rock levers A, A, being in each case in contactual engagement with the head 6, of its own spring shear bolt E, said shear bolt E, being slidably mounted in tubular bearings 6 bored in the brackets B B respectively, and each having a spring e, interposed between its elongate head e,'and the floor .of the recess 5*, which spring tends constantly to maintain the engagement of the elongate head 6, of the bolt E, with the eccentric end o of its rock lever A, and also to retract the shear edge 6 on the lower extremity of each bolt E, within its tubular bearing 6 and out of the adjacent horizontal slot Z1 formed in each bracket B B for the accommodation of the horizontally parallel strands of the binding wire to. The shear ends 6 c of the two bolts E, E, are reversed as related to each other as indicated in Fig. 14, so as to straddle one strand of the binding wire while acting against and severing the other strand thereof, thereby trimming oft the superfluous wire at each end of the twist and adjacent to its outer convolutions, as indicated in Fig. 11, it being understood of course that the length of the twist is effective, essentially, to the distance between the two shear bolts E, as indicated in Fig. 8, of the drawings.

After the ends of the wire binding loop have been secured together by twisting effected by the rotation of the gear 25, they are reversed manually from the gear slot 6, by pushers Q2, (12, mounted slidably in bearings formed for the purpose in the brackets B, B*, as illustrated in Fig. 5 in connection wit-h the bracket 13*, the parts and structure being duplicated in the bracket B, and the actuating levers being united at their upper and outer extremities by the cross bar or handle 9 so that the twin pushers g, are operating simultaneously to effect the ejectment of the twisted ends of the binding wire. Retractile springs Q3, are preferably provided to bear against the lower ends of the actuating levers g, 9, so that the twin pushers g (1 will return automatically to normal positions when the actuating levers q, q, are released.

In the use of my improved wire tightening implement the binding wire to, is first passed around the box or package and through the slots 6 b and t, and then connected with the twin gripping discs Gr, G, by means of the radial slots 9*, 9*, in the face thereof. The hand lever H, is then reciproeated until the wire is drawn taut around the package. During this tightening operation the crank shaft C, and connection are held locked by the spring bolt 8, in engagement with the notch l, on the hub of the locking gear L. Upon the release of the latter by the withdrawal of said bolt 8, the crank shaft C, may be rotated by means of the handle C, until again locked automatically by the reengagement of the bolt 8, (which in the interim rested on the periphery of the hub Z,) with the notch Z, of the hub 7, of said locking gear. During this single rotation of the locking gear L,' the twister geart has been rotated twice (or any other pre scribed number of times as hereinbefore explained) the parallel ends of the binding wire thus being twisted securely together. The cams K, K, are so timed with relation to the locking gear L, that they act to depress the shear bolts E, E, just prior to the completion of the rotation of said locking gear L, so that the superfluous wire of either extremity of the seal twist is trimmed off automatically beyond the convolutions. After the relocking of the crank shaft C, it connects automatically as above set forth the wire seal of the adjacent portion of the binding wire may be released from the slots manually by a simple expedient of locking the ejector-actuating levers 7, g, 9 after which the implement is ready for further use.

My implement is a decided improvement orer any other tool of its kind on the market. Heretofore, tools have been put on the market to be used with flat box strapping, which has proven too expensive. Furthermore, with flat box strapping it was necessary to use a certain kind of seal to hold the ends of the strapping together. That system has not proven altogether economical and therefore round wire has been adopted for strapping all kinds of packing cases. 'ith round wire it is notnecessary to use any seals, which have a tendency to break oil", whereas with round wire the ends of the wire are twisted together, which twist cannot be pulled apart. Round wire therefore, proves more economical.

The round wire, when used, is drawn very tightly around the box with the use of a stretching apparatus, until the wire embeds itself into the corners of the box, and then the ends of the said wire are twisted and the protruding ends are cut off. The twist".

is very strong and of course much stronger than seals. It is very important that the ends of the wire be held securely by the stretching tool, otherwise the wire will give way before the stretching operation takes place. some tools are so poorly equipped that in order that the wire to be held firm, so that it will not yield when the stretching operation takes place, one end of the wire itself must have a notch or some sort of indentation made in it, to fit in some kind of a groove in the stretching tool and then the end of the wire is pulled until the desired tension is reached. Of course when the wire is required to be thus specially made, the cost of same is necessarily increased over that of plain ordinary wire, which the user can purchase anywhere, without waiting for the manufacturer of the tool to supply him with specially constructed wire. My tool is so manufactured that it will take any kind of wire and I claim therefore, that it is a decided improvement over any other tool of its kind on the market.

' In other words my tool is so equipped that an ordinary plain round wire, without any notches or impressions, can be used, this reducing the cost of the wireand it enables the user of such wire to obtain his supplies anywhere, as any steel merchant carries such wire in stock, put up in coils, whereas, if specially manufactured-wire must be used, the packer must wait until he could procure his supply and pay a higher price for same, on account of the additional cost of manu facture of the wire. Furthermore the great er tension applied, the firmer the grip on the wire. My tool serves to pull the wire in both directions which saves a great deal of time in applying the necessary tension to the wire. Other tools simply draw the wire from one end; in my tool, as the wheels turn, the wire is held more securely, thereby enabling the operator to apply a very strong tension on the wire.

A distinctive feature is'that the holding wheels travel in either direction, thus causing the tension to be performed much more quickly than if the wire were pulled only from one direction. I claim, therefore, this to be a decided improvement over any other tool on the market.
