Masonry block cutter

Details

Inventors: Coffman, Leon M.;
Assignee:
Primary Examiner: Whitehead; Harold D.
Assistant Examiner:
Attorney, Agent or Firm: Rose; Alan C.

A masonry block cutter includes four blades. The blades are arranged in two pairs with each V-shaped pair being secured together. When cutting a block having a square cross section, the cutter has a generally square configuration, with the opposed pairs of blades being pivoted at one corner of the square and having spaced-apart elongated handles extending parallel to each other and at an angle of about 45.degree. to the adjacent sides, at the opposite corner of the square. Hammer blocks are provided at the intermediate corners of the cutter, so that, when the blades are resiliently held against the block by the grip of one hand at the end of the handles, the mason may strike one of the hammer blocks and cleanly cut the masonry block at the desired point along its length.

DETAILED DESCRIPTION What is claimed is: 1.
A lightweight portable masonry block cutter comprising: means including a first pair of blades connected to each other for engaging two adjacent external sides of the masonry block; means including a second pair of blades connected to each other for engaging the other two adjacent external sides of the masonry block in opposition to said first pair of blades; handle means for manually urging said blades into resilient engagement with the masonry block around the exterior of said block, and for angularly orienting said block and cutter, means opposite said handle means for connecting said first pair of blades to said second pair of blades for movement toward and away from each other; and means for receiving an impact to move all four of said opposed blades inwardly for cleanly cutting said masonry block in two.
2.
A masonry block cutter as defined in claim 1 wherein the blades of each of said pairs of blades are rigidly connected together.
3.
A masonry block cutter as defined in claim 2 wherein said first pair of blades is pivotally connected to said second pair of blades for movement toward and away from said masonry block.
4.
A masonry block cutter as defined in claim 3 wherein said means for holding said blades in engagement with the masonry block includes first and second handles secured respectively to the first and second pairs of blades at the ends of said pairs of blades opposite from the pivotal connection of said pairs of blades.
5.
A masonry block cutter as defined in claim 4 wherein said handles are resilient and are spaced apart when held together at their ends exert a steady force on said blades against the masonry block.
6.
A masonry block cutter as defined in claim 1 wherein said impact applying means includes hammer blocks provided at the corners where the two blades of each of said pairs of blades are interconnected.
7.
A masonry cutter as defined in claim 1 wherein means including an adapter blade assembly is provided for sliding over one of said blades to cut different size masonry blocks
