t and following turns by suitable clamping means.

In the manufacture of such barricades it is?V found essential te maintain the adjacent turns of the coils in their correct relative position in order to permit of the clamping operation as such would be rendered impossible were there any displacement or tangling of the individual turns.

` The object of the present invention is to provide simple and efcient apparatus for so coiling the wire and maintaining the same in such properly coiled condition prior te the clamping operation, and the invention consists in a machine for ceiling wire comprising a fermer and means for spacing the turns thereon, said means being removable `from the former to maintain the turns in correct relationship after removal of the coil from the machine.

Further features of the invention will be apparent from the description given hereafter.

'Ihe accompanying drawings illustrate one con; venient form oi apparatus in accordance with the invention.

Figure 1 is a longitudinal sectional elevation.`

Figure 2 is an end elevation, and

`Figures 3, 4, 5, 6 and 7 are enlarged views showing various details.

In carrying my invention into effect in one convenient manner I form my improved apparatus with a former of suitable vform upon which the wire is coiled, said former being adapted to be rotated by suitable power means and to be members a carried upon end b secured to` upper and lower plates cd normally spaced apart against the action of springs e by cam members ,f for a reason hereafter described.

The plates c and d are connected to end discs g which are carried by a driving sleeve h adapted te be drivenby suitable gearing for the purpose ci rotating the former during the ceiling operation.

One of the transverse members suchV as the member el isfermed a comb `and is mereclearm ly shown in Figure 6, the teeth of the comb having a pitchref, say, 15`millimetres `er other pitcht depending upon the spacing of the individual turns in theceil. In order to permit of this regular spacing l arrange that the former shall be moved axially during its rotation and this may l0 conveniently be accomplished by arranging the former upon a central stationary spindle .i havingia worm er circular rack k thereon adapted te be engaged by a spring pawl Z and the pitch of the worm or rack being such that for one complete revolution of the former the same will be moved axially through a distance of 15 milli metres or other distance corresponding to the pitch of the teeth of the comb a1.

The driving gear for the fermer will of course have to be arranged to permit of its axial movement and one particular construction is shown in the drawings where the fermer is driven by belt m from a pulley m1 slidable upon a shaft m2 driven from the power shaft n by bevel or other gearing o.

Conveniently the paWl l is spring controlled so that it maybe withdrawn from engagement with the worm and rackv 1c in order te enable the fermer te be rapidly moved to its initial positien after the completion of a ceiling operation. The arrangement is such that the barbed or other wire is evenly coiled upon the former and the turns maintained in spaced relation thereon by the comb d1 and in order that the correct relation may be preserved after the ceiling operation the Wire may be'clamped in position on the comb by means of a slotted bar p (Figures 4 and 5) and the comb with the wire clamped therein is arranged to be removable from the machine. It may, for example, be held in place by a spring i hoot` q at one end and a bail q1 at the other end retained in position by a spring r se that it may be readily disengaged forI removal by disengage ment of the members q q1.

In order to permit of removal of the comb with the complete coil thereon it is clear that the former will have te be collapsible and it is for this reason that the spring controlled plates cd are provided at each end so that when the cams f which are carried upon the sleeve f1 are rotated by means of the lever s (after disengagement from the frame of the fermer by manipulation of the spring-controlled lever s1), the springs e are allowed to pull the plates towards one lanother the construction of coiling former and the means adopted for collapsing the same or otherwise permitting of the removal of the coil from the former and the arrangements provided for driving the former depending upon any practical requirements that may have to be fulfilled.

-I claim:

1. Machine for coiling Wire comprising a former consisting of end supports and a plurality of members carried thereby to form a cage-like device round which the Wire is coiled, one of said members being formed as a comb for spacing the wire turns and a clamp for removably clamping the turns in said comb, the former being collapsible to permit of the removal of the comb with the coil clamped therein.

2. Machine for coiling Wire according to claim 1 having means for automatically moving the `former axially through a distance corresponding of the teeth of the comb and a spring held pawl to the pitch of the teeth of the comb for each revolution of the former.

3. Machine for coiling Wire according to claim 1 comprising movable cam members for holding the cage in its extended position and springs allowed to operate on movement of the cam members for collapsing the cage for removal of the coil. y

4. Machine for coiling Wire according to claim 1 comprising a central stationary shaft about l0 which the cage rotates, a circular rack upon said shaft the pitch of which corresponds to the pitch of the teeth of the comb, and a pawl carried by the cage and co-operating with said rack for moving the cage axially during rotation.

5. Machine for coiling wire according to claim 1 comprising a central stationary shaft about which the cage rotates, a circular rack on said shaft having a pitch corresponding to the pitch carried upon the cage and co-operating with the rack for moving the cage axially during rotation, said paWl being disengageable from the rack for rapid return `of the cage to its initial position.

6. Machine for coiling Wire according to claim 1 having means for moving the cage axially through a distance corresponding to the-pitch of the teeth of the comb for each revolution ofw the cage and gearing for rotating the cage ar-flo ranged to permitA of such axial movement during the coiling operation. f
