connection with the accompanyin drawings, the construction and operation of the invention will be readily understood without requiring n more extended explanation.

Various changes in the form, proportion and the minor deieils of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims.

Having thus described my invention, What I claim is:

1. in a tube bending tool, an anvil block, means whereby said block is held in position for operation, a tube bending block adapted to co-act with said anvil block, said tube bending block having a. recess in its rear face to allow relative lateral movement of the block during the insertion of the tube, a lever freely movable upon said bending block to actuate the tool, and means to prevent said block from slipping during the bending operation.

2. A tube bending tool comprising an anvil block having. formed therein a tube-receiving groove, av base plate upon which the anvil block is secured having its forward end bifurcated to form arms, the latter havlongitudinul guiding grooves in their inner feces a clamping block slidubly mounted between the arms of the base plate and provided with extensions whereby it is slid ably retained within said guiding grooves, a clamping lever pivotnlly mounted be tween said arms and having a rounded end adapted to contact with the clamping block to move the some into engagement with the tube to be bent, a bending block adapted to eoiiperute with the anvil block to bend said tube, and an operating lever having u roller adapted to relatively engage the forward face of the bending block whereby the bending block is mo ed about the anvil block.

in testimony who 'eo'f I have hereunto set my hand in presence of two subscribing witnesses.
