Abstract

The aligning block shown in Figs. Figs. 1 and 2 is designed to be held upright and receive a quantity of headed screws or bolts which are to be aligned with the heads up and the shanks extending through the slots 3. The alignment is effected by vibrating the block with the palm of the hand enclosing the upper opening by being held against the upper wall surface 4.

Adjustable Screw Aligning Block

The aligning block shown in Figs. Figs. 1 and 2 is designed to be held upright and receive a quantity of headed screws or bolts which are to be aligned with the heads up and the shanks extending through the slots 3. The alignment is effected by vibrating the block with the palm of the hand enclosing the upper opening by being held against the upper wall surface 4.

The block is formed as a single piece with side walls 5 and 6. Each junction between a side wall 5 and side wall 6 is formed as a reduced section flexure element or "living hinge" 7. A series of ribs 8 extend between the side walls 6 and define the aligning openings 3 therebetween. Each rib 8 is connected to the side wall 6 with a "living hinge" 9. An arm 10 projects from one side wall 5 as a rigid integral part thereof. An ear 11 is formed as a part of side wall 6 and presents a slotted opening 14 overlying a threaded aperture 13 in arm 10. A bolt 15 extends through slot 14 and is received in aperture 13 to clamp arm 10 and ear 11 in a selected position relative to one another. The legs 16 extending from walls 5 permit the aligning block to rest on a supporting surface with the aligned bolt shanks depending downward through slots 3.

By loosening bolt 15 the walls 5 and 6 may be pivoted into a parallelogram configuration which reduces the width of slots 3 to align a selected screw or bolt shank size. The bolt 15 is thereupon resecured to maintain the slot width.
