France February 25, 1935 8 Claims. (cl. 140-93) This invention relates to .wire tying machines of the well known type comprising chiefly wireclamping means, wire-tensioning means, wiretwisting means and wire-cutting means mounted on a common frame capable of being laid on the bale or other package to be tied by the wire.

The primary object of the invention is to provide a portable machine of this type of a muchv more simplified structure and much cheaper construction than similar machines made heretofore while being capable of perfectly tensioning and twisting a wire of any gauge and of any cross sectional shape with the utmost rapidity.

A further object of the invention is to provide a portable machine of the above type wherein all parts are easily dismountable and replaceable relative to the frame whereby any part can be removed and replaced by a new one when it is worn out or when itdoes not properly work 0 any particular wire.

A still further object of the invention is to provide a portable machine of the above type wherein the frame is made up of independent parts held together by simple means such as bolts and nuts and capable therefore of being dismantled almost instantaneously to gain access to the in-. terior and change the wire twisting or holding means for instance for substituting such a means for twisting a wire of any given size for a similar means which was used for twisting a wire of another given size.

Still a further object of the invention is to provide a portable machine of the above type wherein the parts of which the frame is made up can be manufactured and assembled in series, for instance die cast and bolted to one another andthen fitted with the wire working 'means without requiring skilled labor.

With these and such other objects in view as will incidentally appear hereinafter, the invention comprises the novel construction, arrangement and combination of parts that will now be described with reference to the accompanying diagrammatic drawings showing suitable constructional embodiments of the same and formin a. part of the present disclosure.

Like reference characters denote like parts throughout the several views.

' Reference being first had to the machine shown in Figures 1 to 4 inclusive, it will be seen that 2.5 the frame of this machine comprises primarily a dished end plate I having a base 2 formed with an outwardly flaring notch 3 and an outwardly extending wing 4. The machine frame line also comprises acasing 5 open at both ends of a shape or cross outline matching that of the plate I and having a base 6 notched at I to correspond to the notch 3. The machine frame still comprises another dished end plate 8 provided with .an outwardly extending wing 9. The plates I, 8 and the casing 5 define an enclosure The end plates I and 8 are provided with holes (three in the embodiment illustrated) through, which bolts III, II, I2 can be engaged. Such bolts are fitted with outer nuts I3, I3, I4, Il'

and I5, I5 which, when tightened, hold the parts I, 5, 8 firmly together, and 2. v

In view of this'built-up construction of the frame of the machine, said frame can be dismantled almost instantaneously. Another advantage is that the parts I, 5, 8 can be produced very easily, for instance die cast, any suitable metal or alloy such as brass being utilizable.

The wing 4 on the left hand end plate I has a as shown in Figures 1 hole receiving a, rigid core I6, made for instance of steel, which is held thereinJ-oy a set screw I'I. The core' I6 carries a small anvil I8 projecting from one of its faces. In an\ eccentered hole sa formed in the core i8 is revolubly fitted a boss l9 the periphery of which is knurled or otherwise roughened, as shown at 18a. The eccentered boss l8 carries a hand lever 28 clamped thereto by a screw 2| and nut 22.

By rotating the hand lever 28 clockwise or anti-clockwise, the boss l8 can be moved away or towards the anvil l8 for releasing or clamping the end of the wire, as will be described hereafter.

The end frame plate i has a pair of holes through which are journalled the ends of a pair of shafts 23, 24 the opposite ends of which are journalled in corresponding holes formed in the end frame plate 8.

The shaft 23 extends outside the right hand side of the machine frame. and is carried by a bearing 25 forming an extension of the wing 8 of the end plate 8. The free end of the shaft 23 removably carries a handle 26 clamped by a threaded pin 21. A small pinion 28 is fast on the shaft 23 inside the frame casing 5.

The shaft 24 carries a pinion 29 meshing with the pinion 2B and with another pinion 30 the body and hub of which protrude on both sides of its teeth. This pinion 38 has a deep radial notch 3| of flaring outline extending through its toothed part hub and body as in the type of wire tensioning and twisting machines which the invention is improving. The purpose of said pinion 30 is to twist the two lengths of wire received in its notch 3! so as to produce a pair of wire twists or knots on both sides on said pinion. The notch 3| much coincide with the notch 'l of the casing 5 so that the two lengths of wire may be readily inserted thereinto preparatory to the twisting operation. I

The casing 5 is fitted with a wire guide 32 having a flaring notch registering with its notch I as shown in Fig. 4 and adapted to receive the two strands of. wire and to prevent them from overlapping while they are being subjected to the twisting stress by the notched pinion 30. The wire guide 32 may be held in position by any known means such as screws and may be replaced by another when it becomes worn out or when a wire guide having a notch of a given size must be substituted for a wire guide having a notch of another size.

On the bolt I2 is pivotally mounted inside the hollow end plate 8 and substantially at right angles to said bolt a small elongated steel plate 33 having a nick 33a in its lower edge. The latter is sharpened adiacent said nick to permit the plate 33 to act as a cutter or knife for cutting off one strand of the wire while the other strand is received in the nick 33a and thus protected from being cut, as will be described hereinafter. To the knife 33 is anchored one end of a spring 34 anchored at its opposite end to a pin 35 carried by the frame plate 8. The pivotal motion of the knife 33 across the wire guide 32 takes place against the action of the spring 34. The upper edge of the knife 33 has such an outline as to cooperate with a toothed-shaped cam 38 fixed to, or formed on, the shaft 24. Owing to this arrangement, at each revolution of the shaft 24, the cam\3 8 depresses the knife 33 against the action of the spring 34, and the knife cuts off the outer strand of the wire while the inner wire strand is protected in the nick 33a as aforesaid.

The outwardly extending wing 8 of the end frame plate 8 carries a stud 31 fitted with a hand lever 38. The stud 31 carries at one'end a wiretensioning wheel 38 having spaced cuts 38a in its periphery and at its opposite end a ratchet wheel 40. A pawl 40a anchored to a peg 43c is associated with the ratchet wheel 40. The cuts or indentations 38a in the tensioning wheel 39 are adapted to receive a bight of the strand of wire to which a tensioning stress must be applied.

The operation of this machine is as follows: When it is desired to tie or encircle a bale or a similar package with wire, the machine is laid or crawled on any face of said bale and one end of a wire of suitable size is inserted between the anvil l8 and the boss IQ of the wire-clamping means, whereupon by rotating the hand lever 20 anti-clockwise said end of the wire is clamped between the anvil l8 and the knurled groove l9a of the boss IS. The wire is then passed through the notch 3| of the twisting pinion and through the notch in the wire guide 32 and bent around the bale to be tied, and again passed into said two notches which thus receive two strands of the wire. The end of the wire opposite to the one clamped between l8 and I9 is passed through two or more indentations 38a of the wire-tensioning wheel 38 and the hand lever 38 is imparted a reciprocating motion so as to rotate the wheel 38 in the proper direction for tensioning the wire, a rotation in the reverse direction being prevented by the ratchet wheel 48 and pawl 40a. By then rotating the handle 26 clockwise, the gear 28, 23 transmits its rotation to the twisting pinion 33 which produces two knots or twists of wire on either sides of said pinion. The cam 38 carried by the shaft 24 then comes into engagement with the upper edge of the knife 33 and depresses the latter against the action of the spring 34, which cuts the outer. strand of wire, as above-stated. By then rotating the hand lever 20 clock-wise, the end of the wire may be released and the machine taken off the bale which is now positively and permanently tied or encircled with wire.

Reference being now had to the modified machine shown in Figures 5 to 9 inclusive, it will be seen that the general construction is the same as in the constructional form shown in Figures 1 to 4, the corresponding parts being designated by like reference numerals.

The constructional differences may be described as follows: The frame casing interposed between the side plates I and 8 is made up of two parts 5, 5 having bases 6, 6 and juxtaposed side by side and held together removably by the bolts l l, u l2, l3. The shafts 23 carrying the handle 26 is fitted with a pinion 28 of the same size as the pinion 29 fitted on the shaft 24 and meshing with the sinaller twisting pinion 30, so that one revolution of the handle 26 in the direction disclosed ll by the arrows e, f, g is suflicient for performing the wire-twisting operation, as aforesaid.

The arrows a, b show in what respective direc-- tions the hand lever 28 must be rotated for clamping or releasing the end of the wire located between the small anvil l8 and the boss IS. The arrows c, 11 show in what respective directions the hand lever 38 must be rotated for rotating the tensioning wheel 33 under the control of the ratchet wheel 40.

it will again be seen that the general construction is the same as in the two constructional forms described above, the corresponding partsbeing designated by like reference numerals.

Theconstructional differences may be described as follows: The pinion 28 fittedflon the shaft 23 carrying the handle 26 meshes with a twice smaller pinion 29a fitted on the shaft 24 carrying the pinion 29 which meshes with the twisting pinion 30. The gearing'ratio of the gear 23, 29, 29a is such that it is sufficient to impart half a revolution to the handle, as shown-by the arrows 11., i, a and by the interrupted line k (Fig. 14) to perform the wire-twisting operation. Therefore the machine is specially adapted for use where one or more complete revolutions could not be imparted to the handle 26, for ,instance when encircling with wire bales or similar packages of very large size. v

For the sake of easier manipulation of the machine, there is provided a bail 46 having parallel legs 44, 45 formed with holes engaged over the ends ofthe bolt i and held by the clamping nuts l3. The legs of, the bail 46 might also be held by the bolts l0, l2 simultaneously.

As illustrated, the shaft 23 projects outside the side plate 8 only to a small extent so that the handle 25 does not protrude much outside the overall outline of the machine, which is thus rendered still less cumbersome than in the two other constructional forms as above described.

.The pawl or dog 40a is held inpermanent en'- gagement with the teeth of the ratchet wheel 40 by a small coilspring 40b abutted againstthe that whatever the constructional form of the machine according to the invention may be, the

objects of the latter are accomplished since the structure of said machine is extremely simple, its dismantling merely requires disengagement of the bolts III, II, l2 and all operative parts of the machine can be easily replaced by others when required, either for accommodating a wire of another cross sectional size or for another purpose incidental to the use of the machine. For instance the notched twisting pinion 30 may be easily taken oil the casing or 5,- 5' and replaced by another pinion having a notch of another size capable of receiving a wire of a different cross section. 'The knives 33, 4| may be replaced by others very easily. Dismantling the machine, substituting one or several parts for others-and re-erecting the machcine into operative condition only requires one or two minutes and can be performed without requiring skilled labor, by the user of the machine himself.. A cheap set of spare parts can be supplied to the user by the manufacturer.

It is obvious that those skilled in the art may vary the details of construction without departing from the spirit of the invention which, therefore, must not be regarded as limited to the above disclosure execpt as may berequired by the claims.
