UNITED STATES DANIEL TAYLOR, OF LAWRENCE, YIVIASSACI'IUSELTS.
MACHINE FOR STRAIGHTENING DROP WIRES.
`Application filed May 19, 1925.
To all whom t may concern:
Be it known that I, DANIEL TArLcn, a citizen of the UnitedStates, residing at Lawrence, in the county of Essex and State or Massachusetts, have invented certain new and useful Improvements in Machines for Straightening Drop Wires, of ywhich the following is a specification.
This device krelates to machines for straightening certain classes of wires or metal strips, without heating.
It is particularly useful for straightening what are known as drop wires, which are used in connection with warp stop motions on looms.
These wires are made of mild steel with light temper, and are of an elongated Ushape with two long legs at one' end and a loop at the other end.
On account of the Operation of the machinery one or both legs are frequently bent so that the wire becomes useless unless this bend can be straightened out. This cannot be done in a satisfactory manner by hammering or by any other method, and the wires are therefore thrown away.
My machine is devised for the purpose of straightening wires, and particularly drop wires, as the old wires have become smooth by use and are more satisfactory than new wires, and my machine permits wires to be continuously used until they are entirely worn out.
In the drawings, Fig. 1 is a plan view ol my preferred type of machine shown attached to a table, and with a. drop wire in position, having one leg bent and about to be straightened.
Fig. 2 is a vertical sectional View, substantially on line 2-2 of Fig. 1, some parts being omitted for clearness.
Fig. 3 is a view similar to Fig. 2 showing a drop wire in position about to be straightened, and also its position shown by dotted lines after it is straightened.
Fig. 4 is a view from the side, on which is the operating handle showing a slight modification of the pulling handle.
Fig. 5 is a sectional view Online 5 5 of Fig. 1, looking in the direction of the arrow.
Fig. 6 is a sectional view on line 6--6 of Fig. 5, showing one position of the cam and jaws, in the open position.
Fig. 7 is a view similar to Fig. 6, showing the cams and jaws in the closed position.
In the drawings, T represents a table hav- Serial No. 31,323.
ing an end 22 to which, by means ot a bolt 6,
and wing nut T, the base B is firmly fastened.
A represents a drop wire having the fiat legs 10, 11, and 13, and elongated hole 12.
C represents a iiXed jaw attached to base VB by means of' a plate 32 and screws 33, Jaw C has spaced teeth 30, the ends ci' which are prei'erably smooth and rounded and which are alined.
D represents a movable jaw which is slidable on base B under a plate 42 which is fixed to base B by screws 43.
The returning spring E at one end has a loop 3S by which it is alixed to one of the 70 screws 83, and its other end 48 is bent down vertically into a hole 148 in movable jaw D.
I provide near one end of jaws C and D, which I will call the entering end, means for advancing that end ot' the movable aw 75 towards the fixed jaw, which I will call pressure means.
This includes post 49 which passes into and is revoluble in a hole 149, in base B, and this is cut away adjoining D, to form a cam 41.
A pressure handle. K is fixed to 49 above cam 41 by means of nuts l and 2, the end of post 49 at 147 being so formed as to make handle K and post 49 turn together.
This pressure handle K is so adjusted that when the jaws C and D are open it projects diagonally beyond the side 8 of block B, and it has a depending end 4 which, when the jaws are closed, extends down just outside the back end 112 of base B.
As shown in Fig. 1, it is also cut away at 3 so that when the pulling handlel H is operated, it Will move pressure handle K from the full line open position shown' in Fig. 1, 95 to the dotted or closed position.
N is a hook which I call gripping means as it can be passed through hole 12 in a dro wire A, and as it is attached to a chain which I will call pulling means, it will pull the drop wire between the teeth of the aws when the chain G is pulled.
This chain G is attached to a staple 52 on a barrel 53 fixed to the pivot shank 54 of pulling handle H. 55 is the main shank of 105 H, and 5G the handle.
When this handle H is turned from the full line position in Figs. l and 2, to the dotted line position, Vit revolves barrel 53, pulls chain G and hook N, and draws the wire A between the alined teeth 40 and 30.
These teeth 40 and 30 are each positioned out away part Y3 of handle K, these beingso adjusted that they will co-operate.
lThe handle VVH maybe shaped as shown in Fig. 4 at l), being pivoted at 8O and having the handle end 8l while the part 82 between them bends down and up, and extends out opposite the end of K whereby the cut away part 3 is unnecessary.
On account of theY fact that the cam which `forces the jaws together is nearer the entering end than the delivery end, the pressure on the wire is greatest at the entering end, and at the Vdelivery end is just sufficient to release it gradually, and without creating any final kink.
The tips of the teeth or jaw are alined, and their Yfaces are preferably rounded;
At the entering side of the aws, when the handle K is operated the teeth slightly intersect and Yslightly crimp the wire, whileat the other end they barely tough each side of 'the wire so that it can be released without difficulty. i
There may be a slight pivotal action at the end 48 of the wire spring E but the tendency is to force the exit end of the jaws apart and keep the entrance end together.
prefer that the height of each jaw should be a trifle over the height or width of each leg as I prefer to straighten one leg at a time, but it is obvious that the jaws might be high enough to take in both legs at a time. l
The pulling of the wire should be directly in line with the space between the jaws, but this is taken care of with my flexible chain which serves as a pulling member.
