  "abstract": "A pulley system for a weight lifting apparatus includes a swivel bracket attached to a V brace bracket on one side and a pulley bracket on the other side along with a V brace attached to the V brace bracket, and a pulley attached to the pulley bracket. This arrangement of the V brace, the V brace bracket, the swivel bracket, the pulley, and the pulley bracket along with a plurality of first washers collectively form a main assembly. The main assembly is fastened to a beam on the weight lifting apparatus using a conical tapered nut.",
  "claims": [
    "1. A pulley system for a weight lifting apparatus, comprising: a swivel bracket attached to a V brace bracket using a first bolt and a first locking nut positioned on a rear side of the V brace bracket; a V brace attached to the V brace bracket using a plurality of V brace attachment bolts and V brace attachment nuts; a pulley bracket attached to the swivel bracket using a plurality of friction-reducing first washers, a second bolt, and a second locking nut; and a pulley attached to the pulley bracket with a third bolt and a third locking nut; wherein the V brace, the V brace bracket, the swivel bracket, the pulley, and the pulley bracket along with the plurality of friction-reducing first washers collectively form a main assembly, wherein the main assembly is configured to be secured to a beam by inserting the first bolt through a hole in the beam, wherein the main assembly is fastened to the beam using a conical tapered nut, thereby facilitating fit on the weight lifting apparatus, and wherein the V brace is configured to rotate up to 90 degrees when the first bolt is loosened.",
    "2. The pulley system of claim 1, wherein the conical tapered nut is designed with a conical taper, allowing for a thread attachment mechanism onto the first bolt that passes through multiple different sized holes in the beam of the weight lifting apparatus.",
    "3. The pulley system of claim 1, wherein the plurality of V brace attachment bolts and the V brace attachment nuts connecting the V brace to the V brace bracket are designed in a manner to provide restricted rotation of the swivel bracket.",
    "4. The pulley system of claim 1, wherein the V brace is tapered to resist twisting forces and provide stability during a workout.",
    "5. The pulley system of claim 1, wherein the pulley bracket is adjustable along the swivel bracket to accommodate different angles of pull.",
    "6. The pulley system of claim 1, further comprises a lifting cable guide mechanism attached to the main assembly for controlled movement of a lifting cable.",
    "7. The pulley system of claim 1, wherein the conical tapered nut includes a locking mechanism to prevent loosening during a workout.",
    "8. The pulley system of claim 1, wherein the main assembly supports handles, bars, lifting cables, and ropes for different workout options.",
    "9. The pulley system of claim 1, wherein the pulley is a wheel with an inner bearing and a grooved rim whereby the lifting cable is to be threaded, and wherein the pulley is detachable from the pulley bracket to enable quick installation and replacement of the lifting cable.",
    "10. The pulley system of claim 1, wherein the first washers are friction-reducing washers made up of polymer-type material, and atleast a second washer is made up of metal.",
    "11. A method for installing a pulley system onto a weight lifting apparatus, the method comprises: attaching, a swivel bracket to a V brace bracket using a first bolt and a first locking nut positioned on a rear side of the V brace bracket; securing, a V brace to the V brace bracket with a plurality of V brace attachment bolts and corresponding V brace attachment nuts; attaching, a pulley bracket to the swivel bracket with a plurality of first washers, a second bolt, and a second locking nut; mounting, a pulley onto the pulley bracket with a third bolt and a third locking nut; inserting, a main assembly comprising the swivel bracket, V brace bracket, V brace, pulley bracket, pulley, and first washers, wherein the main assembly is configured to be secured to a beam by inserting the first bolt through a hole in the beam of the weight lifting apparatus; and connecting, the main assembly to the beam of the weight lifting apparatus using a conical tapered nut allowing to secure a thread onto the first bolt that passes through multiple different-sized holes on the weight lifting apparatus, wherein the V brace is configured to rotate up to 90 degrees when the first bolt is loosened.",
    "12. The method of claim 11, wherein the plurality of V brace attachment bolts and the V brace attachment nuts connecting the V brace to the V brace bracket are designed in a manner to provide restricted rotation of the swivel bracket.",
    "13. The method of claim 11, further comprises adjusting the position of the pulley bracket along the swivel bracket to accommodate different angles of pull.",
    "14. The method of claim 11, further comprises attaching a lifting cable guide mechanism to the main assembly for controlled movement of the lifting cable.",
    "15. The method of claim 11, further comprises selecting the V brace bracket and the V brace with dimensions compatible with a plurality of weight lifting apparatus."
