Abstract:
A wire feeding pulley A-Frame System is provided for feeding electrical, telephone, communication wires ect into manhole, transformers, switch gears ect., including a frame having four vertical rails one horizontal rail at the top which has four short pieces of square tubing welded to it which the vertical rails sleeve over and are held together by horizontal pins. The bottom of the frame has four horizontal pieces welded into a square that have four short vertical pieces welded on top of them that the vertical rails can sleeve into and be held together by horizontal pins. It has three vertical pieces of square tubing welded to the bottom side of the top horizontal rail that three pulleys can be attached to for wire to be fed through. There is also a square tube that can be attached to the bottom frame that has a smaller square tube inside of it that has a pulley that pins on the end of it, making it a snorkel attachment for feeding into devices with small doorways.

Description:
BACKGROUND OF THE INVENTION 
     It is often required to feed electrical, telephone wires ect. Into manholes and switches. There are numerous designs of pulleys and wire feeding systems that are made to protect wires once they have entered manholes. However, currently the devices for feeding them from above ground before and while they enter the manhole still allow wires to tangle or be damaged and require a lot of human handling of the wires themselves to keep them in the right order for proper feeding. 
     SUMMARY OF THE INVENTION 
     It is the intent of the invention to address the aforementioned issues. 
     In one aspect of the invention, an A-Frame pulley system assembly for feeding wire is provided where the A-Frame has at least 2 pairs of upright side rails. The A-Frame assembly includes two u-shaped frame pieces that are connected to make a square shaped base. The U-shaped frame pieces each have a pair of short rails and a elongated center rail connecting to each end of the side rails. The side rails are connected to each other by a pair of connecting links in the that are sleeved into each open end of the u shaped frame pieces attaching them together making the pair of u-shaped frame pieces into a square base. The two pairs of upright side rails are sleeved down into the brackets that are welded on top of the corners of the u-shape frame pieces. The two pairs of upright side rails have open square ends on the top of each one of them that the top horizontal rail of the A-frame can be attached to by four smaller square tubing pieces that are welded to the bottom of the top horizontal rail being sleeved down inside of the end of the two pairs of upright side rails completing the A-frame shape. The top horizontal rail has three square tubing pieces that are welded to the bottom of the beam for pulleys to be attached to for wire feeding. The top horizontal rail also has a bracket welded to the side for a pulley to be placed for retrieving workers out of manholes with a retrieval system hoist. 
     ADVANTAGES 
     The A-Frame Pulley System allows you to feed wire into a manhole off of three reels at once without anyone having to turn the reels by hand or anyone having to stand over a manhole and feed the wire over their shoulder. The advantage of having three separate pulleys at different heights is that your wire will not be able to twist around each other and the wire will not get damaged while it is being fed into the hole.
