A tool block comprises plates providing therebetween a tool holder guide channel for preventing movement of a tool holder along two of three orthogonal axes while permitting slidable adjustment relative to a workpiece along the third or adjustment axis. A pair of preload blocks normally clamp the tool holder against movement along the adjustment axis. A pair of forked shaped wedges straddle the tool holder and are adjustably received in recesses cut in opposite sides of the tool holder. Each wed...

A terminal receiving snap latch type connector block having an improved flexible latch. Application of a force tending to pull the terminal from the block distorts the latch for improved terminal retention.

A dolly block for selective association with a wheel dolly of a conventional type adapted to support wheels of a vehicle for towing purposes and the like, the conventional dolly being selectively modified by use of the dolly block to support an automobile wheel drum when the tire and wheel are disassociated from the drum. The modified support eliminates the necessity for a vehicle leaf spring resting on a dolly pan and enables moving of an automobile even though the tire and/or wheel have been r...

The illustrated gage block has all of the advantages of a cylindrical gage block, together with the versatility of a rectangular gage block. The block has three pairs of diametrically opposite surfaces which are parallel with three rectangularly related axes. At least the surfaces of the first pair are cylindrically curved and constitute segments of a cylindrical surface centered about the first axis. The second and third pairs of surfaces are illustrated as rectangularly related parallel plane ...

A building block of hollow box-like form, shaped at its ends and at top and bottom for interfitment with adjacent similar blocks of a course, and with similar blocks of succeeding courses, has its sides interconnected by a cross-member with an enlarged middle portion having an opening formed therethrough from top to bottom, the cross-member being such that in a wall of the blocks, the openings through cross-members of blocks of the courses are vertically aligned and are adapted to receive a vert...

Individual terminal stations receive electrical terminals with bussing bars bridging selected terminal stations, the bars having fingers extending to the selected stations.

There is disclosed a press such as a hydraulic press for forming form-retaining blocks by compacting powderized or fibrous material. The press comprises two pressure containers which are pivotal about a common axis for automatically and selectively placing the containers in a filling position and a compression position, respectively. The bottom of each container consists of a pressure plunger which is slidable in the respective container and can be releasably locked in any selected axial positio...

The chain block includes a holding frame having bearings to support intermediate gear of reduction gears mechanisms mounted on one of a pair of side plates. The frame is formed into a channel shape so as to cover the reduction gear mechanisms and is positioned by the projections at the ends of both legs of the holding frame being brought into engagement with the engagement holes in the side plate and fixed to the side plate by being pressed against the side plate by a gear cover mounted on the s...

A block having a plurality of steps of different heights and useful as a stepladder for reaching different heights, depending on the size of the person. By laying the block selectively on any one of the three side and base surfaces, about nine different levels of height can be achieved. A pair of such blocks with a scaffoldboard inbetween supported at selective heights may be used for wall cleaning and the like.

The invention comprises a method of erecting a wall or like construction from a plurality of similar regular shaped blocks, and a means for carrying out the method, including the utilisation of a pair of spacer or form strips initially maintained in spaced relationship by a plurality of transverse tie members which are preferably separable from the strips, the spacer or form strips being arranged for location between adjacent blocks at the front and rear peripheral edge portions thereof during b...
