Abstract

A holding device for holding pipes in a chain vise includes an angled bracket, a plurality of teeth, and a pair of chain guide slots. The angled bracket has a top surface, a bottom surface, and lateral surfaces. The angled bracket includes a first bracket portion, a second bracket portion, and a central bracket portion. The bottom surface is angled less than 160 degrees. The teeth are on the bottom surface and designed to engage and grip an upper portion of a pipe positioned on a jaw of a chain vise. The chain guide slots are positioned in the first and second bracket portions, and thereby divide the portions into a pair of legs extending away from the central bracket portion. The chain guide slots are designed to receive and guide between the pair of legs portions of a chain of the chain vise placed on the top surface.

Description

(b) CROSS-REFERENCE TO RELATED APPLICATIONS Not Applicable (c) STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT Not Applicable (d) THE NAMES OF THE PARTIES TO A JOINT RESEARCH AGREEMENT Not Applicable (e) INCORPORATION-BY-REFERENCE OF MATERIAL SUBMITTED ON A COMPACT DISC OR AS A TEXT FILE VIA THE OFFICE ELECTRONIC FILING SYSTEM. Not Applicable (f) Statement Regarding Prior Disclosures by the Inventor or JOINT INVENTOR Not Applicable (g) BACKGROUND OF THE INVENTION (1) Field of the Invention The disclosure relates to chain vises and more particularly pertains to a new holding device for improving the gripping ability of chain vises. As is well known, chain vises are tools that have a toothed jaw mounted on a support, which is affixed to a table or similar. A pipe is placed on the jaw, and then a chain is wrapped around the pipe and tightened and locked in place. The chain and the jaw work together to hold the pipe and prevent rotation. However, many chain vises still suffer from slippage of the pipe, especially as the chain and jaw become worn over time. The new holding device is placed on the upper surface of the pipe seated in the jaw of the chain vise, between the chain and the pipe, to provide two separate gripping forces on the top and bottom of the pipe to prevent the pipe from sliding or rotating when being cut or having screw threads cut therein. (2) Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98 The prior art relates to chain vises. The prior art, as best understood, does not disclose a holding device that includes an angled bracket, a plurality of teeth, and a pair of chain guide slots. The teeth are positioned on the bottom surface of the angled bracket and are designed to engage and grip an upper portion of a pipe positioned on a jaw of a chain vise, and the chain guide slots guide a chain of the chain vise placed over the top surface of the angled bracket. (h) BRIEF SUMMARY OF THE INVENTION An embodiment of the disclosure meets the needs presented above in a holding device generally comprising an angled bracket, a plurality of teeth, and a pair of chain guide slots. The angled bracket has a top surface, a bottom surface, and lateral surfaces connecting the top surface and the bottom surface. The angled bracket includes a first bracket portion, a second bracket portion, and a central bracket portion connecting the first bracket portion and the second bracket portion. A first section of the bottom surface positioned on the first bracket portion and a second section of the bottom surface positioned on the second bracket portion form an angle less than 160 degrees. The teeth are positioned on the bottom surface. The teeth are designed to engage and grip an upper portion of a pipe positioned on a jaw of a chain vise. Each of the chain guide slots is positioned in a respective one of the first bracket portion and the second bracket portion. Each of the chain guide slots is positioned to divide a respective one of the first bracket portion and the second bracket portion into a pair of legs extending away from the central bracket portion. Each of the chain guide slots is designed to receive and guide between the pair of legs portions of a chain of the chain vise placed on the top surface of the angled bracket.
