Abstract
Abstract Telescoping columns, particularly a method for developing a plurality of telescoping forms as a rigid stand for a roadside sign, high tension wires or the like, by anchoring a plurality of forms to a rigid base and pumping the forms simultaneously with fluid concrete, so as to vertically telescope the forms above the rigid base.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
Method for developing a multiple pole stand comprising: A. anchoring to a rigid base at least two telescoping forms of the type including a stationary bottom member encompassing a plurality of longitudinally aligned, interlocking telescoping sections; B. pivotally joining the tops of said forms with a crossmember; C. simultaneously pumping fluid concrete into said bottom members and into said forms, so as to vertically extend said telescoping sections above said bottom members; D. maintaining fluid pressure within said forms, so as to rigidize said sections upon the setting of the concrete with respect to said base; and E. measuring the level of the tops of said forms and varying pumping of said concrete into respective forms, so as to maintain said crossmember in a desired plane interconnecting said form tops.
Claim 2
Dependent Claim
130 words
Method for developing a multiple pole stand comprising: A. anchoring to a rigid base at least two telescoping forms of the type including a stationary bottom member encompassing a plurality of longitudinally aligned, interlocking telescoping sections; B. pivotally joining the tops of said forms with a crossmember; C. simultaneously pumping fluid concrete into said bottom members and into said forms, so as to vertically extend said telescoping sections above said bottom members; D. maintaining fluid pressure within said forms, so as to rigidize said sections upon the setting of the concrete with respect to said base; and E. measuring the level of the tops of said forms and varying pumping of said concrete into respective forms, so as to maintain said crossmember in a desired plane interconnecting said form tops.
Claim 3
Dependent Claim
18 words
Method for developing a multiple-pole stand as in claim 1, wherein said measuring is done by visual sighting.
Claim 4
Dependent Claim
25 words
Method for developing a multiple-pole stand as in claim 1, wherein said measuring is done by a mercury switch governing said pumping into respective forms.
Claim 5
Dependent Claim
57 words
Method for developing a multiple-pole stand as in claim 1, wherein there are at least three forms horizontally joined at their tops by a horizontal member and an intermediate form, including delaying pumping of fluid concrete into said intermediate form, until the telescoping of said outer forms by pumping of fluid concrete has extended said forms vertically.
