Abstract
Abstract An adjustable stand for supporting attachments adjacent a machine tool table. The stand has a base on casters for easy movement, and a telescopic upright extends upwardly from the base. A tilting mechanism is attached to the top of the upright and supports an auxiliary table to which attachments may be fastened. The telescopic upright and titling mechanism combine to permit adjustment of the height and angular position of the auxiliary table to match the position of the machine tool table.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
280 words
An adjustable stand for supporting stock feed attachments and the like adjacent a machine tool table, the stand comprising: a base; a telescopic upright having upper and lower ends and attached at its lower end to the base, the telescopic upright comprises: lower, intermediate and upper members, the intermediate member being slidably engaged in the lower member, and the upper member being slidably engaged in the intermediate member, said members being restrained to substantially prevent rotation of one of the members relative to another of the members, the intermediate member defining an Opening adjacent its upper end, and the upper member defining at least two openings spacedapart vertically for selective alignment with said opening in the intermediate member; a pin for engagement in said openings to lock the upper member in said selected position in the intermediate member; a plate attached to the lower end of the intermediate member; and jack means for adjusting the vertical separation of said ends of said telescopic upright, the jack means comprising a screw jack housed in the lower member below the intermediate member and bearing against said plate so that adjustment of the screw jack results in up and down movement of the intermediate member together with the upper member; a tilting mechanism attached to said upper end of the telescopic upright, the tilting mechanism including an upper part and a lower part and means connecting said parts for adjusting the angular relationship of said upper part about a longitudinal axis; and an auxiliary table coupled to said upper part for movement therewith so that said table may be moved into a desired position by actuating said jack means and said adjusting means.
Claim 2
Dependent Claim

An adjustable stand for supporting stock feed attachments and the like adjacent a machine tool table, the stand comprising: a base; a telescopic upright having upper and lower ends and attached at its lower end to the base, the telescopic upright comprises: lower, intermediate and upper members, the intermediate member being slidably engaged in the lower member, and the upper member being slidably engaged in the intermediate member, said members being restrained to substantially prevent rotation of one of the members relative to another of the members, the intermediate member defining an Opening adjacent its upper end, and the upper member defining at least two openings spacedapart vertically for selective alignment with said opening in the intermediate member; a pin for engagement in said openings to lock the upper member in said selected position in the intermediate member; a plate attached to the lower end of the intermediate member; and jack means for adjusting the vertical separation of said ends of said telescopic upright, the jack means comprising a screw jack housed in the lower member below the intermediate member and bearing against said plate so that adjustment of the screw jack results in up and down movement of the intermediate member together with the upper member; a tilting mechanism attached to said upper end of the telescopic upright, the tilting mechanism including an upper part and a lower part and means connecting said parts for adjusting the angular relationship of said upper part about a longitudinal axis; and an auxiliary table coupled to said upper part for movement therewith so that said table may be moved into a desired position by actuating said jack means and said adjusting means.
Claim 3
Dependent Claim
75 words
An adjustable stand as claimed in claim 1 in which said connecting means comprises: an axle coaxial with said longitudinal axis and pivotally interconnecting said parts; a worm gear rotatably mounted on said lower part; and a gear wheel attached to the upper part coaxially with said axle and in mesh with the worm gear whereby rotation of the worm gear results in rotation of the gear wheel and upper part about said longitudinal axis.
Claim 4
Dependent Claim
35 words
An adjustable stand as claimed in claim 2 and further comprising casters attached to the underside of the base for supporting the base to permit the stand to be moved from one location to another.
