A diagnostic system for measuring acceleration of a piston of a reciprocating hammer is disclosed. The diagnostic system may include a magnet configured to induce, via electromagnetic induction and based on a movement of the piston, an electric current in a conductor. The diagnostic system may include a capacitor electrically coupled to the conductor and configured to store electric power based on the electric current induced by the magnet. The diagnostic system may include an accelerometer configured to measure an acceleration of the piston. The diagnostic system may include a communication device powered by the capacitor and configured to output a signal that identifies the acceleration measured by the accelerometer.

The invention provides a block splitter device comprising first lower and second upper opposed block splitter assemblies. The block splitter assemblies have first and second forming edges that extend at least the majority of the distance from a first end to a second end of the block splitter assembly and have first ends disposed near a median split plane and second ends disposed further away from the median split plane than the first ends. Methods of using the block splitter device are described.

Disclosed is a hammering device (1) comprising a hammer (2), an elongated linear carriage guide (3) including a first guide end (4) and a second guide end (5) at eithers ends of the elongated linear carriage guide (3) and a hammer carriage (6) arranged to be displaceable back and forth along the elongated linear carriage guide (3). The hammering device (1) further comprises a lifting line (7) connected to the hammer carriage (6) and to the hammer (2), so that the hammer (2) is displaced in response to displacement of the hammer carriage (6), wherein the lifting line (7) is extending from the hammer carriage (6) in a direction towards the first guide end (4). The hammering device (1) also comprises a displacement carriage (8) arranged to be displaceable back and forth along the elongated linear carriage guide (3), and displacement means (9) connected to the displacement carriage (8) and arranged to displace the displacement carriage (8), wherein the displacement carriage (8) is arranged between the hammer carriage (6) and the first guide end (4). Furthermore, a method for operating a hammering device (1) is disclosed.

A masonry block that is produced from a workpiece that is split in a block splitting assembly which uses any of a variety of projections to supplement or replace the action of the splitting blade in splitting and dressing the workpiece. The resulting masonry block has features that provide the masonry block with a weathered appearance.

A long-bladed bolster has a substantially planar cutting body having one edge formed as a blade of sufficient length so that the blade is arranged, in use, to be positioned substantially centrally on a Concrete masonry unit (CMU) to enable the block to be divided without the bolster requiring repositioning. The bolster, has a striking body on a second long edge of the cutting body, opposite to the cutting blade, configured to receive repeated blows from a striking implement in use and to transmit these blows through the cutting body to the blade. The bolster has an integral handle that extends from the cutting body and/or striking body of the bolster substantially centrally along the length of the cutting body and substantially orthogonally to the plane thereof.

A multifunction masonry tool includes a handle adapted to be held firmly in the grip of one hand. The handle is a polygonal solid, with for example four sides arrayed in generally rectangular or square cross-sectional arrangement. A narrow neck is disposed adjacent to a first end of the handle to enhance the grip of the thumb and forefinger. A loop extends from one end of the handle and a pick extends from the opposed end, both formed of a hardened, form-retaining rod material. The pick and loop may be formed from a single piece of the rod material that extends axially through the handle.
