Claims5
A portable C-clamp device comprising
- a body portion made of rigid material and formed in the configuration of the letter "C"
- said body portion having a bight portion extending longitudinally and having longitudinally spaced apart arms extending laterally from said bight portion at right angles thereto,
- said arms forming a jaw for receiving an article to be clamped and held by said device,
- one of said arms having anvil means against which the article to be clamped and held is seated,
- the other of said arms having longitudinally movable adjustment means for closing said jaw by drawing selectively closer and away from said anvil means, thereby to effect clamping of the article,
- a pad having a slip joint connection on said adjustment means for engaging the article to be clamped and held,
- and bar means detachably connected to said pad,
- said bar means when so connected to said pad in functional relationship with said clamp being of sufficient length to engage said bight portion and thereby prevent rotation of said pad as it is longitudinally adjusted.

A C-clamp device made of rigid material and shaped in the form of a letter "C" with a bight and upper and lower arms disposed at right angles to the bight to form a clamping jaw,
- jaw closing means comprising a threaded rotatable rod carried for adjustable movement in the upper arm and anvil means in the lower arm, whereby an article to be clamped is grasped therebetween,
- a pad rotatably carried on said rod having a bar means extending laterally so that it cannot move past the bight and will thereby prevent rotation of the pad, and
- a stud on the lower arm carrying a ball joint mounting a pad, thereby to afford a swivel pad on said anvil means for engagement with the clamped article.

- said arms forming a jaw for receiving an article to be clamped and held by said device,
- one of said arms having anvil means against which the article to be clamped and held is seated,
- the other of said arms having longitudinally movable adjustment means for closing said jaw by drawing selectively closer and away from said anvil for closing said jaw by drawing selectively closer and away from said anvil means, thereby to effect clamping of the article,
- a pad having a slip joint connection on said adjustment means for engaging the article to be clamped and held,
- and bar means detachably connected to said pad engageable with sigh bight portion to prevent rotation of said pad as it is longitudinally adjusted,
- said bar means and said pad have a mated threaded coupling affording selective attachment and detachment therebetween.
