To all whom it may concern: 1

Be-it known that I, CHARLES E. HADLEY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Wire-Covering Machines, of which the following is a full, cle'aiyand exact description, reference being had to the accompanying drawings. 1

This invention relates to wire insulating machines of that class wherein threads are wrapped around a continuous strand of wire.

As to features, the invention contemplates the use of certain mechanism for winding the thread about the wire, for laying it smooth upon the wire, for controlling the supply of threads to the winding device, for preventing the racing of the bobbin, and for stopping the whole machine upon the breaking of the thread. This last feature of the invention is one of the most important, since it prevents the machine from running ahead with the winding operation when the threadhas been dropped or broken and insures a continuous insulation being laid on the'wire.

The invention also embodies certain other features of construction which will be more fully hereinafter disclosed, and consists in the construction and combination of parts set forth in the following description, drawings and claims. I A

Description of the drawings.Referring to the draw ings, Figure 1 is a side elevation of the machine showing all the parts in their proper relation to each other. Fig. 2 is a side elevation of a portion of the machine representing parts in section to more clearly show their construction,-this view being taken about the parts at the forward end of the machine or the left hand end,

as shown in Fig. 1, looking from the'other side. Fig.

2 is a cross section of the thread laying shoes. Fig. 3 is a sectional view upon the line 3'3 of Fig. 1. Fig. 4 Fig. 5 is a top plan view of the rear portion of the machine showing the thrust bearings in section. Fig. 6 'is a detailed view of the thread laying device; Fig. 7 is a' detailed view of a portion thereof on the line,7.7 of Fig. 6; Fig. 8 is a detailed view of the brake for stopping the motion of the entire machine. Fig. 9 is an end elevation looking from the left of Fig. 8; and Fig. 10 is a front elevation of the brake shown in Fig. 8 but with the mounting plate removed from the frame to more clearly show the construction. i

- The general construction of the machine is such that the wire is delivered from a reel or any other suitable means to the forward .or left hand end of the machine, as shown in Fig 1. From here it passes to the first thread laying device, where a series of threads is wound upon the wire in one direction. It passes direct from here to another thread laying device which is ar-' ranged to lay a series of threads in the opposite direc-' tion and upon the thread already laid. The wire then passes to the drawing drum which serves to feed the wire .through the machine. From this drum it may pass to any suitable winding mechanism, not shown.

The frame. The frameconsists of two long standards A which are constructed in a manner such that they will support all the parts and give sufficient rigidity for the perfect operation thereof. To these standards are-secured braces A which hold them spaced apart a sufiicient distance to accommodate the different mechanisms.

The power mechanism.Mounted longitudinally in substantially the center of the frame and between the standards A, and upon the braces A, is the main driving shaft B which runs through the entire machine and has upon its end, at the forward part of the machine, a loose pulley b, and a tight pulley b. A belt from any suitable driving shaft may be carried by these pulleys. Keyed to the shaft B is a thread laying driving gear b near the forward end of the machine, and another thread laying driving gear I) at a considerable distance therefrom. This shaft B is also connected through a train of worm gearing to a shaft B which has keyed thereto a gear wheel I)". The end thrust of the shaft B, caused by the, worm gearing, is taken up by a thrust bearing B Wire delivery and guiding mechanism.-The mechanism for delivering the wire to the machine and for drawing it through the same consists of any suitable guiding means at the forward end for delivering the wire in position to the first thread laying device, of a guiding block 0 adjacent to said device, a protecting tube 0 for protecting the insulation between this device and the next thread layingdevice, another guiding block C, a second protecting tube 0 and a drum D, which is secured upon a shaft 11 mounted in suitable bearings to the flame. The'wire takes several turns around this drum D and the operating face thereof is made to taper, as shown in Fig. 4 to keep the wire in substantially the center of the protecting tube 0.

The shaft d receives its rotation from the gear d which meshes with the gear b, which in turn is rotated by the main driving shaft B.

The belt shipper and brake.Pivoted to one of the standards A is a pair of shipper arms E and E which are pivoted substantially at the midway point of their \length to across bar e. A spring e secured at one end to theframe has a tendency to draw this bar e to the left and swingthe two=shipper arms Eand E to the left also. .A belt hook e issecuredto the arm E for engaging the belt' and shipping it from the loose to the tight pulley, as desired, the normalvtendency being for the shipper to holdthe belt upon the loose pulley b through the tension of the spring e. j' The belt, however, during the operation of the machine, is held upon the tight pulley b by means of a trip engaging the stop 0 upon the bar a. This trip and its operating mechanism will be hereinafter described.

In order to stop the rotation of the main driving shaft B immediately upon the-stoppage of the machine, a brake is provided, as before stated. This brake consists of an arm F, arrangedso that one end thereof is loosely mounted on a stud in arm E andis adapted to slide in a block f secured to the frame A, and carrying a shoe f having a leather covered face for engagement with the crown of the pulley b. When the belt is operating upon the pulley b this shoe, by reason of its connection with the arm E, is shifted out of engagement with the crown of said pulley, but,

upon the arm E being thrown to shift the belt upon the loose pulley, a friction roller f on the back of this shoe, travels along the cam face f rigid with the block f, whereby the shoe is forced rigidly against. the crown of the pulley, thus stopping the motion of. the pulley and of the main driving shaft B. The roller f is mount ed loosely upon a pin f carried by the shoe f. I

The mechanism for setting free the brake to the action of the spring 0 consists of atrip, mounted in. suitable bearing brackets secured to the frame A and a rock shaft Gr having keyed thereto a trip 9 which is arranged to co-operate with the stope upon the bar e.

This trip g engages upon the front side of the bar e and.

behind the stop e and holds the arm E to the right, as shown in Fig. 1 against the tensionof its spring e, while the belt is operating upon the pulley. An operating arm 9 is keyed to the rock shaft G in a position to be engaged by a tripping mechanism carried by the winding device. A spring 9 secured tothe frame. is arranged to draw this arm g into the path of the machine receives its rotation through an idle pinion,

H loosely mounted upon a stud h secured to the frame. This pinion H meshes with a pinion I rigid with the hollow spindle 1', arranged to carry the thread winding frame J, the bobbin K and the thread laying shoes M v The thread winding frame I is secured to the hollow spindle i, rotates therewith, and .is constructed substantially as shown with the diametrically opposed arms j, each of which has projecting rearwardly an arm, as j or 9' This duplication of arms'is provided in.

order to properly balance the frame andrnake its operation as regular as possible.

The arm j carries aneye j t hrough whiclrthe series of threads pass. This same arm 9" also carries the device for actuating the operating arm g, and this device. is

what may be termed a centrifugal device for throw-' ing off the power, since it is thrown out by centrifugal force against the thread, and when the thread is removed therefrom, it will be moved into position,.

where it may operate the arm 9. This device-consists of a member-f, which is pivotally mountedupon a pair of links j and another pair 3'', and carries at one end a sheave j for receiving the thread from the bobssaam bin. These links are inturn pivoted to the arm j so that the member 3' may be thrown out by centrifugal force away from the arm j, butthis member is constructed in a manner such that a portion'of'it, when thrown by such force, will travel in a path which is interrupted by the arm g whereby when said arm is engaged, it will be operated, thus operating the trip g and setting free the bar a to the action of the spring with the results consequent thereto.

- The member j" is preferably prevented from being thrown out, by the tension ofthe thread over the sheave 3' upon the end thereof. The machine, however, may be provided with a spring 9? which is arranged to draw, said member to the right as shown in The bobbin Kcarries the thread X, wound tightly upon the same, and alsohas rigid therewith a large grooved wheel lc, as shown. A groove k of this wheel is engaged by a'shoe j rigidly carried by the spring lever j. The arrangement of the cam j and of the mounting of the spring lever jiupon the arm j, is such, that when the member j is thrown outward, the cam will cause a downward movement of the free end of the spring lever j, and force the shoe j into the groove it, thus increasing the resistance to rotationv of the bobbin, but. since the increasing of the resistance to .rotation of the bobbinnecessarily operatesto' draw the thread tighter over the sheave 3' the member ,7' will be drawn in toward the arm. j and, through the cam connectionwith thebobbin brake, the drag on the bobbin wheel will. be removed and the thread will'be loosened. These different parts cooperate to retain the thread. taut at all times. 7

The connection between the pair of links 3' and the cam is an adjustable one, and is arrangedin a manner such,-that there is a concentric circle of holes j in the cam 3' to beengaged by a pin j carried in suitable openings in the pair of links j, Plates 3' are arranged to retain this pin in place, but are provided with peripheral notches j which serve the purpose of permitting the pinto be removed whenthe links are movedto bring the pinto register-with the same. From this, it will be seen that the cam may be adjusted relative to the links 3', and the member 9? made to receives the thread from the bobbin and delivers it.

to the sheave 7' carried by the member 9''. From here the thread passes to the eye 3' .at the forward end of the arm 9', and is, then wound. about the wire, which is being fed through the machine. As long as there is-a continuous web of thread from .the bobbin through the opening J, over the sheave 9', through the eye j and to the wire to be covered, there isa restraining action brought to bear upon the member 7' dependent upon the force exerted by the brake shoe 9' but since the pressure of this brake is dependent upon the position of the cam j, and the position of the cam is dependent upon the position of the member 3' and further, since the position of the member 9' is dependent upon the centrifugal force brought to bear upon said member by the rotation of the same, there will be an equalization through these parts, and the thread will always be kept taut from the bobbin to the wire regardless of the size of the ball of thread upon the bobbin. Should the thread give out, however, or should it become broken, a restraining action of the thread upon the member 3' will necessarily cease, consequently this member will be thrown out further by centrifugal force, and its rear end will engage the operating arm 9 of the tripping mechanism with the consequent result;

I of fiber and are mounted upon the vfree ends of arms m rigid with the guide m in a manner such that they bear with considerable force upon the insulation. Thus it will be seen that when the thread is wound upon the Wire it will be smoothed or ironed out, as it were, upon the wire.

This completes the description of the operation of the entire machine with respect to the first thread winding device. The other thread winding device, as before stated and represented by the frame N, is of the same construction as the one previously described, but its operating spindle n receives its rotation from the gear wheel I) in a manner such that it rotates in the opposite direction to the spindle i. An operating arm 9 is arranged to be operated in a similar manner to the arm 9 whereby the power will be thrown off upon the breaking or the giving out of the thread in connectio with this threadwinding device.

Shaft and bearing casings.-A case B is provided about the thrust bearing and it extends under the thread winding device to prevent the hanging threads from being wrapped around the main driving shaft B. Another casing B is arranged upon the main driving shaft B underneath the first thread winding device for a similar purpose. 7
