Description: |
| Charles H. Fowler - patent attorney
This invention relates to that class of lifting-jacks provided with a metal rack-plate secured to the elevating bar or lift; and the object of the present invention is to provide such a bar or lift with a rack-plate that will fit thereon in such a manner as to prevent the wood composing the said bar or lift from becoming split by lateral strain upon the fastening-screws, it being usual to have the under surface of the plate perfectly flat and secured upon the top edge of the bar or lift by screws. The invention therefore consists in forming the rack-plate with a recess or groove upon its under side to form flanges, which embrace the sides of the bar or lift, and thereby prevent the splitting of the wood by the lateral stain upon the screws holding the plate thereto.
I claim as new, and desire to secure by Letters Patent, is;
In a lifting-jack having the usual standards and pivoted operating-lever, the combination, with the bar or lift A, connected to said lever by pivotal link E, of the metal rack-plate B, recessed or grooved upon its underside to form flanges a for embracing the sides of the bar or lift, and secured thereto by screws or other like fastenings, substantially as and for the purpose set forth.
