2 Claims. (01. 81- 13) Our invention relates to holding appliances for turnbuckle connections of cables and has as its object the provision of an emcient and serviceable device by which the screw ends of a cable may be conveniently held against turning while the turnbuckle is adjusted.

Our invention particularly concerns control cables of aircraft which are of the stranded wire type havingspecial fittings at the ends for furnishing screw connections for the turnbuckle.

The fittings are swedged or otherwise secured on the cable and supplied with. hexagonal parts by which they can be held at rest while the turnbuckle is rotated in making an adjustment. It is most important that both fittings be simulta- .The device comprises a pair of

members

5, 5 for individually gripping the heads D of the cable fittings. The members are interconnected by means of an extensile element 6 which serves as a" handle to enable the device to be manually held during adjustment of the turnbuckle.

The gripping members 5, .5 are of identical con struction and each comprises a tubular stock I flattened at an end to compose a jaw 8 in which is formed a V-shaped face 9 transversely disposed receptive to a corner of the hexagonal head D of a cable fitting. The stock 1 is cut away intermediate of its length to provide a guideway lflfor neously held while the turnbuckle is adjusted otherwise the stranded cable may be damaged. This cannot be accomplished in asatisfactory manner by conventional tools because the mechanic must have at least one hand free to rotate.

' device by which the companion fittings can be held'simultaneously against turning while adjustment is made to the turnbuckle. The device is a unitary member which is designed to supply ample leverage for manually resisting the turning action induced by rotation of the turnbuckle.

The invention consists in the novel construction and arrangement of parts of the holding device as described in the specification and I claimed in the claims forming a part thereof.

The invention is illustrated in the accompanying drawing in which Fig. 1 is a general aspect of the device showing the manner in which it is attached to the cable.

Fig. 2 is a side view of one of the two gripping tools which are of like construction.

Fig. 3 is a cross section on line 3-3 of Fig. 1.

Like numerals of reference v indicate corresponding parts throughout the figures of the drawing. 1

In the practical embodiment of the invention shown in the drawing the device is arranged to straddle the turnbuckle juncture of a cable A formed of stranded wires whose ends are rigidly attached to screw fittings B with which the turnbuckle Cis engaged. The fittings have the usual nut-like heads D of a hexagonal cros section for engagement with a tool to preclude their turningv in the application and adjustment of the turnbuckle.

ashank H of a Slidable jaw l2.

The shank II, which is a round rod, is slidably contained in the bore [3 and has an ofiset part l4 extending outwardly of the guideway and upwardly of the jaw 8. The distal end of part I4 projects over the jaw 8 and is fashioned to form the slidable jaw I2, which has an inner V-shaped face receptive to the opposite corner of the hexagonal head D.

The offset part Id of the shank is guided in a keeper [5, which is a U-shaped member having its ends integral with the base portion of the jaw 8. The keeper thus takes the stress imposed on the offset part of the shank in the use of the device. The shank projects from the bore l3 and is threadedly engaged with a knurled nut it which tightens the jaws on the head of the fitting.

The extensile element compises a pair of arms I! pivoted at an end to each other as at E8 and having their other ends each pivoted at I9 by means of a yoke 20 to the stock 1 of the gripping members. The arms have their interconnected ends curved toward each other and are of such a length that they are disposed at an acute angle with each other when the jaws are attached to the heads D. The interconnected ends form an elbow'portion that constitutes a handle by which the device is held to preclude the cable ends from turning while the turnbuckle is being adjusted. The arms are disposed in the plane of the stocks and extend oppositely to the jaws. The jaws oi each gripping member are disposed at right angles to the plane in which the arms spread, and it will be evident that the pivotal connections l9 enable the gripping elements to maintain a parallel relation with each other as the arms spread or contract in adjusting the turnbuckle.

The device can be readily attached to a cable by fitting each element on an end thereof with its jaws firmly engaged with the head portion of a. fitting. The arms of the extensile element permit the gripping members to be properly spaced according to the distance between the heads, and also accommodate relative axial movement between the heads caused by tightening or loosening the turnbuckle.

The device may be used on cables of various sizes and is admirably suited for airplane riggers and others whose work entails the adjustment of turnbuckles.

What we claim is:

1. In a tool for holding cable ends of a turnbuckle connection, an extensile element for spanning the turnbuckle connection and havingspreadable parts, gripping members connected individually to.the spreadable parts, comprising a tubular stock cut away intermediate of its length to form a guideway, a jaw rigid with anend of the stock, a movable jaw disposed outwardly of said jaw, a round shank carrying'said movable jaw having a part of its length slidable in said guideway and in the bore of the stock, said shank also having a part of its length oifset outwardly of the guideway and alongside of the first mentioned jaw to support the movable jaw,

a U-shaped keeper mounted on the stock having side portions flanking the offset part of the shank and its bight encircling the same to take the stress on the movable jaw, anda nut threadedly engaged with the shank and shouldered on the stock for adjusting the movable jaw.

2. A tool structure as set forth in claim 1 and in which the jaws of the gripping members are fashioned with V-shaped faces for gripping opposite" corners of a nut-like enlargement which is supplied'on the cable ends.
