The present invention will now be describd by way of example only and with reference to the under noted drawings but firstly I would like to draw attention to my European patent 0047635 which describes and claims a head for rotating a threaded fastener. I wish to make it clear that mention of my European patent 0O47635 herein does not in any way constitute an admittance of my prior patent as being prior art to my present Invention because there is no suggestion in my prior patent of the invention described and claimed therein as being used for anything other than rotating a threaded fastener. -nus there is no disclosure therein of the new uses described with respect to my present invention.
In mentioning my prior patent EP 0047635 I merely wisn to highlight certain differences in structure which facilitate the practise of my present invention.

Figure 6 illustrates the starter device of the present invention in use to start the petrol engine of a iawnmower.
Figure 7 illustrates the starter device of the present invention in use to start he petrol engine of a chain saw.
Figure 8 illustrates the prime mover of the present invention used to operate a generator to provide an emergency light.
Figure 9 illustrates a prime mover according to the present invention fitted to a drill chuck.
As shown in figures 1 and 2 a tool 10 for turning a nut or bolt comprises a wrench head 12 formed by an upper annular casing 14 and a bottom piate 16 and having mounted for rotation therein an annular drum 18 constituting a drive member and provided with an integral upper reel 20 and a lower reel 22. Around the upper reel 20 is wound a steel tape 24 , the inner end of which is anchored to a piliar 26 accommodated in a circumferential cut-out in the reels 2, 22 and the outer end of whIch projects through an aperture in the casing 14 and terminates in a ring 28. Around the lower reel 22 is wound a coil spring 30, the inner end of which is anchored to the lower part of the pillar 26 and the outer end to the casing i4 by a rivet 32. The drum is provided Ith a sKeW bore 34 in which is received a ball 36 ioaded by a spring 3:: and retained in position by a sleeve 40 which is an interference fit in the axial bore in the drum 18 and has an orifice which allows a segment of the ball 36 to project into an arcuate-section groove 42 running around a stub shaft 44 constituting an output shaft which is rotatable within the sleeve 40.
As shown in figures 3 and 4 a portable hand operated device 60 according to my present invention comprises a plastic housing 61 made up of two similarly shaped casings or halves 62, 63 abutting and connected to each other at junction 64 by interlocking projections and/or suitable adhesive. The plastic lightweight housing aids portability of the device and the housing 61 made in two similar halves aids in reducing production costs. This contrasts with the head shown in my European patent 0047635 with its differently shaped upper and lower casings. An annular drum member 65 is mounted for rotation within housing 61 constituting a drive member and provided with an integral upper reel 66 and a lower reel 67.Around the upper reel is wound a flexible cord or line 68, the inner end of which is held at 75 in a crimped tube inserted in an angled radial hole in reel 66 and the outer end of which projects through an aperture in the housing 51 and terminates in a suitably shaped handpiece 70 shown in figure 4. Around the lower reel 67 is wound a coil spring 71, the inner end of which is anchored to a pillar 69 and the outer end of which is anchored around steady pin 72. The handpiece 70 of my present invention is more easily grasped and manipulated than the pull ring 28 disclosed in EP 0047635 thus facilitating easier operation of my present invention. Drum member 65 is provided with two counter-projecting cavities 73, 74 formed parallel with a main axis 59 of the device 60 and in each of which is received an anti-friction roller 76, 77.Each roller 76, 77 is loaded by a spring 78, 79 inserted within cavities 73, 74 and retained therein by means of washer 80 and resilient circlips 81, 82. The two counter projecting cavities 73, 74, provide a better balanced arrangement than the sinale acting skewed bore arrangement shown in EP 0047635. A hollow hub member 83 co-operates with the annular drum member 65 and is retained axially relative thereto also by means of resilient circlips 81, 82 and with drive being transmitted thereto from drum 65 through the spring loaded rollers 76, 77. This arrangement facilitates assembly of the device since it avoids the need to use the interference fit of sleeve 40 in the device of EP 0047635.Hollow hub member 83 is formed with detents 84 to facilitate the fitment thereto of various adaptors suitably shaped to accommodate connections to the apparatus to be used in conjunction with the device of the present invention. A pin 72 is arranged to be a sliding fit within casings 62, 63 as shown in figure 3.
Pin 72 is used to steady the device 60 when in use either by holding pin 72 or by abutting the piece of apparatus with which the device 60 is currently being used. In use tne device of the present invention will usually be used in combination with an adaptor member designed to fit the particular connection member provided on the selected piece of apparatus to be started or operated. A number of such adaptor members are illustrated in figures SA to 5G. Figure 5A illustrates an adaptor comprising a plain drive key. Figure SB illustrates an adaptor having internal and external threaded portions. Figure 5C illustrates an adaptor having threaded holes for receiving clamp screws. Figure SD illustrates an adaptor fitted with grooves for accommodating proprietary circlips and can have splined connections.Figure 5E illustrates an adaptor comprising drive dogs. Figure 5F illustrates an adaptor provided with threaded lock rings as an alternative to fixing clips.
Figure 5G illustrates a drive dog adaptor with a "throw-out" capability, that is a tapered cam shape which will be automatically ejected by the engine. As will be evident this list is by no means exhaustive and, indeed, the adaptor could be left blank to be modified in accordance with the design of the particular apparatus with which the device of the present invention is to be used or a small chuck for a variety of small tools could be used. It is envisaged that the apparatus to be started or operated will be provided with a built-in connection member arranged to co-operate with the device of the present invention with or without an adaptor member as described herein but that the buiit-in connection member on its own will be unable to start or operate the apparatus.The adaptor members can be provided in the form of a kit in combination with the device of the present invention or on their own. Figure 6 shows a starter device 85 according to the present invention with cord or line 86, handpiece 87 and steady pin 88 applied to a connection member 89 on the petrol engine 90 of a lawn mower 91. Figure 7 shows a starter device 92 according to the present invention with cord or line 93, handpiece 94 and steady pin 95 applied to the connection member 96 of the petrol engine 97 of a chain saw 98.In accordance with the method of starting according to the invention the starter device 85, 92, is fitted to the connection member 89, 96 of the particular piece of apparatus to be started, the free end of the cord 86, 93 is pllg by pulling on the handpiece 87, 94 to rotate the drum at a speed designed to start the lawnmower 91 or the chain saw 98. if the lawnmower 91 or chain saw 98 does not start on the first pull the resilient member will effect the return of the line 86, 93 so that the method can be repeated until starting Is achieved. In figure 8 a prime mover device 102 with steady pin 103, pullcord 104 and handpiece 105 is shown in combination with a generator 100 to energise a lightbulb 101.In use the prime mover device 102 is applied to the generator 100 and the fast rotation produced by pulling on the handpiece 105 one or more times enables the generator to energise light bulb 101. Since the prime mover 102 of my invention is small and portable and requires no batteries it can provide a useful light and some warmth for emergency situations, for example, for potholers and mountain climbers. In figure 9 a prime mover 106 with pull cord 107 and steady pin 108 is shown in combination with chuck device 109 to operate a drill 110. In use the prime mover device 106 is applied to the chuck device 109 and the fast rotation produced by pulling on pull cord 107 one or more times enables the chuck device to rotate the drill 110 at a speed required to carry out a drilling operation This combination is shown in operation with a steady pad 111 which is used to apply pressure during a drilling operation. The steady pad can also act as a protecting cover when the device of my invention is used as a starter for engines.
