Description: |
| Abstract:
M1y invention relates to a device for supporting temporarily and in au upright position a door, n incloWv-sash, plank, or board, so as to readily enable a carpenter or operator to plane off or operate upon the upper edge surface of the article while being supported. I employ for the means of supporting such articles two jaws or supports, which lie upon the floor or place surface and are separated at the facing ends, being joined together by a spring-band, being adapted to be adj ustedl toward and from each other upon the spring. Their facing ends, by said spring, when not in use, are thrown up from a horizontal position, spreading the ends of the supports, between which the material to be held is placed. The weight of the material causes the facing ends of said supports to drop, thereby impinging upon the ar- ticle, thus holding the same in an upright position.
Claim:
In a device for the purposes set forth, the combination of the jaws, each provided with a ledge at the joining ends, said jaws coupled ro together by means of the spring, and having the rod and thrum-nut for adjusting said jaws. |
