Abstract

The assembly comprises a rotatably mounted capstan member, a pulley member having an annular groove and a line guide means including a gate portion to direct the movement of the line from the capstan member onto the pulley member. The pulley member is mounted to rotate with the capstan member. The line guide means is disposed in fixed relationship with respect to the capstan and pulley members. The assembly of this invention may be used in combination with a power source to form a line pulling device.

Claims (9)

1. An assembly for pulling a line comprising: a. a capstan member and a pulley member rotatably mounted around a stationary center post, b. said pulley member having an annular groove and mounted to rotate with said capstan member, and c. line guide means including a gate portion to direct the movement of the line from the capstan member onto said pulley member, d. said line guide means being disposed in fixed relationship with respect to the capstan and pulley members, e. the gate portion includes a disk member disposed between the rotatably mounted capstan member and a pulley member, and f. the line guide means includes a bracket portion extending from the disk member to the center post to fix the position of the disk member with respect to the rotatable capstan and pulley members.
2. In a device wherein a power source is operatively connected to a mechanical combination for pulling a line, said mechanical combination comprising: a. a capstan member and a pulley member rotatably mouNted around a stationary center post, b. said pulley member having an annular groove and mounted to rotate with said capstan member, and c. line guide means including a gate portion to cause the line to move from the capstan onto said pulley member, d. said line guide means being disposed in fixed relationship with respect to the capstan and pulley members, e. said pulley member including a plurality of ribs and troughs disposed transversely to the circumference of the annular groove and at regular intervals along the surface thereof, f. said gate portion includes a disk member disposed between the rotatably mounted capstan member and pulley member, g. at least a section of the disk member extends outwardly from the periphery of the capstan and pulley members and has an opening therein located to direct movement of the line from the capstan member to the pulley member, h. said line guide means includes a bracket portion extending from the disk member to the stationary center post to fix the position of the disk member with respect to the rotatable capstan and pulley members.
3. A pulley assembly for pulling a line comprising; a. a rotatably mounted capstan member, b. a pulley member having an annular groove and mounted to rotate with said capstan member, and c. line guide means including a disk member fixedly disposed between the rotatably mounted capstan member and pulley member, d. at least a section of said disk member extending outwardly beyond the peripheries of the capstan and pulley members and having an opening through which the line moves onto the pulley member after it leaves the capstan member.
4. An assembly for pulling a line comprising: a. a capstan member and a pulley member which are mounted to rotate about a common axis of rotation, b. the pulley member having an annular groove and being adapted to rotate in unison with said capstan member, and c. line guide means disposed in fixed relationship with respect to the capstan member and the pulley member, d. said line guide means including a gate portion to direct the movement of the line from the capstan member onto said pulley member, e. said gate portion extending in a direction transverse to the periphery of the capstan member and the pulley member and along which gate portion the line moves as it winds directly onto the pulley member after it leaves the capstan member.
5. An assembly as defined in claim 4 wherein said gate portion includes an opening through which the line moves as it winds onto the pulley member after it leaves the capstan member.
6. An assembly as defined in claim 4 wherein said gate portion includes two guiding surfaces between which the line moves as it winds onto the pulley member after it leaves the capstan member.
7. An assembly as defined in claim 4 wherein the line guide means includes a means to disengage the line from the annular groove of the pulley member after the line has moved from the capstan member to the pulley member.
8. An assembly as defined in claim 4 wherein the pulley member includes means disposed within the annular groove to enhance the gripping action on the line.
9. An assembly as defined in claim 4 wherein a plurality of ribs and troughs is disposed transversally to the circumference of the annular groove and at regular intervals along the surface thereof.
