Abstract
A line puller designed to accept a Working line (15) through a Working Line Fairlead (14), directing the line around a Capstan (21), and through a brake (28). This line puller is mainly driven by gears or friction rotational devices (38), driving the internal face or cogs (36) of a Capstan. The design allows users to load a Working Line (15) from midsection not requiring the end of the line to load the puller. The puller can be hard mounted or Soft mounted using an Anchor Line (44) fed through incorporated Anchor Fairleads (20). Multiple gear rations allow users to pull objects at different rates.

DETAILED DESCRIPTION AND OPERATION
(6) Body
(7) The embodiment of the endless line winch consists of two plates that make up the body. The Body Plates (12, A) provide axel mounting holes (16, ABC). The Number of holes is a function the number of driver or idle mechanisms incorporated. The body plates provide a mounting point for a fairlead, for both a working and Anchor line. The Working Line and Anchor fairlead (20, A) is formed from opposing tabs cut out of the Body Plates. The tabs are pressed in a radial fashion such as to contain the Working Line (15) or Anchor Line, but allows removal and installation without the line termination. The Working Line is any elongated flexible member such as a rope or wire. The holes in the Body Plates provide bearing surfaces for a drive axel. Drive Axels (30, ABC) transfer rotational force to a drive wheel. Drive Axels can contact the body directly or a bearing may be installed to reduce friction and prevent wear. Bearing may be made of any material such as metal or plastic and could resemble a bushing or a ball bearing. The foreseen embodiment of the bearings is seen to be plastic bushing (42, ABC). Drive Axels Transfer rotational power from a lever or external power source such as a power drill. Rotational power can be applied to bother ends of the Drive Axels. The Drive Wheels (38,ABC) transfer rotational movement from the drive axels to a Capstan. Drive wheels can be made of any material such as metal or plastic. Drive Wheels can transfer power to the capstan through mechanical or friction methods. Drive Wheels of different sizes translate different ratios to the Capstan (21). One embodiment of the Capstan is the have internal cogs (36) to receive power from said Drive Wheels. The Drive wheels support the Capstan due to the spacing of the mounting holes and the diameter of the drive surfaces. The Capstan receives rotational power from the Drive Wheels, creating a pulling force on any elongated member (Working Line (15)) wound around it's circumference. One embodiment of said capstan is to have texturing or material applied to increase friction. The Texturing (22) could be a knurling of the surface, cut grooves or additional material. Mounting holes located on the Body Plates proved locations to attach Plate Fasteners. The Plate Fasteners (18,ABC) connect the body and encompass a Standoff. One embodiment of said Plate Fasteners is a mechanical mechanism like a bolt and nut. The Standoff (34,ABC) is seen to be cylindrically shaped and slightly longer the the width of the Drive Wheels and Capstan. The standoff should allow fasteners to securely attach each side plate without producing unneeded compressional friction on the capstan or drive surfaces. An Internal Pawl could be installed using a Standoff as a bearing surface. The internal Pawl (40) is designed to eliminate reverse rotation. The Internal Pawl contacts the internal cogs on the capstan. The pawl is torsional loaded with a torsional Spring. The Torsional Spring (41) will apply effort to one side of the Pawl. The Pawl is then forced into contact with the Internal Cogs of the Capstan. The Internal Pawl is not limited to this embodiment. The Body Plates have a mounting hole for an external brake. The external Brake (28) is designed to keep the Tow Line in contact with the Capstan as well as prevent overrides. The External Brake thought to have an external surface designed to increase friction. This surface could be knurled or soft rubber. This embodiment is thought to have a One Way Bearing. The One Way Bearing would allow the external brake to rotate with the capstan and lock into place when capstans is not under rotation. Said Brake would be mounted on a Brake Lever with a Fastener. The Brake Lever (24) is mounted to the brake and to a Body Plate with a Fastener (26). The brake lever is loaded with a Torsion Spring. The Torsion Spring (25) is installed at the pivot point of said lever and on the body plate. The Torsional Spring forces contact between the external Brake and the Capstan or Working Line. The working line can be secured with a secondary brake. The Secondary Brake (29) comprises of an diminishing angled slot, cut into a body plate providing friction and compression as the working line progresses towards the narrowing end of the slot. This embodiment can be anchored with an Anchor Line. The Anchor Line (44) is thread through and Anchor Fairlead (20, A) Through the two Anchor Points (32, A) and through the second Anchor Fairlead (20,A). The Anchor Points and the Anchor Fairleads keep the device from rotating when torque is applied to the mechanism. The anchor Line between the Anchor Points creates a Purchase Attachment. The Purchase Attachment (46) creates an Attachment point for the end of the working line after running around a tow or through a block.
(8) The above detailed description contains many specificities, these should not be construed as limitations on the scope, but rather as an exemplification of on embodiment thereof. Other embodiments may have features but not limited to such as molded body plates, molded standoff points, handles, meters, intergrated motors and such. Material body and components may differ.
