Abstract
Abstract A pair of upright stands are provided and include enlarged bases by which the stands may be supported on variously elevated support surfaces. Each of the stands has a vertically elongated support mounted thereon for adjustable vertically positioning therealong. Each stand has a double scale having a center point thereon by which the corresponding support may be precisely adjusted above and below a predetermined position on the stand and each support includes a similar double scale reading in opposite directions. Each support includes structure for supporting a transparent hose end in vertical position thereon and for adjustable vertical shifting along the support. Also, each support includes a second double scale thereon which is double the first scale and the first and second scales on each support include center points which are horizontally aligned and registrable with the center point on the scale formed on the corresponding stand. A pointer is provided on each support for vertical positioning therealong and registry with the second scale of the support and a hose extends between the supports and has its opposite ends extending upwardly along and adjustably supported from the corresponding supports, each hose end including a manually operable air valve.

Total Claims: 11
Claim 1
Independent Claim
226 words
A pair of upright stands, a pair of supports mounted on said stands for adjustable positioning therealong, clamp means carried by each of said supports, transparent vertical tubular members removably supported from said supports by said clamp means for adjustable longitudinal shifting relative to said supports, a flexible hose section extending between and communicating the lower ends of said tubular member, said stands including vertically extending first scales thereon relative to which said supports are adjustable, said scales each including predetermined portions thereof spaced the same distance above the lower ends of said stands, said predetermined portions of said first scales comprising corresponding mid-portions thereof, said first scales each comprising a double scale including top-to-bottom reversed upper and lower sections thereof extending above and below the corresponding predetermined portion thereo, each of said supports having a vertically extending second scale thereon corresponding to the first mentioned scale but with the upper and lower sections thereof reversed top-to-bottom relative to the corresponding upper and lower sections of the first scales, said tubular members being longitudinally shiftable relative to the corresponding second scales, said supPorts comprising sleeve members slidable on said stands, the upper and lower ends of said supports including portions registered relative to corresponding portions of the upper and lower sections of the corresponding first scales when said supports are in predetermined positions on said stands.
Claim 2
Dependent Claim

A pair of upright stands, a pair of supports mounted on said stands for adjustable positioning therealong, clamp means carried by each of said supports, transparent vertical tubular members removably supported from said supports by said clamp means for adjustable longitudinal shifting relative to said supports, a flexible hose section extending between and communicating the lower ends of said tubular member, said stands including vertically extending first scales thereon relative to which said supports are adjustable, said scales each including predetermined portions thereof spaced the same distance above the lower ends of said stands, said predetermined portions of said first scales comprising corresponding mid-portions thereof, said first scales each comprising a double scale including top-to-bottom reversed upper and lower sections thereof extending above and below the corresponding predetermined portion thereo, each of said supports having a vertically extending second scale thereon corresponding to the first mentioned scale but with the upper and lower sections thereof reversed top-to-bottom relative to the corresponding upper and lower sections of the first scales, said tubular members being longitudinally shiftable relative to the corresponding second scales, said supPorts comprising sleeve members slidable on said stands, the upper and lower ends of said supports including portions registered relative to corresponding portions of the upper and lower sections of the corresponding first scales when said supports are in predetermined positions on said stands.
Claim 3
Dependent Claim
37 words
The combination of claim 1 wherein said supports each has a vertically extending third scale thereon corresponding to said second scales, but with the scale of each third scale one half the scale of the second scale.
Claim 4
Dependent Claim
27 words
The combination of claim 2 including a horizontal pointer assembly supported from and vertically shiftable along each of said supports in registry with the third scale thereof.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
30 words
The combination of claim 1 wherein each of said tubular members includes a ring member disposed thereabout, shiftable therealong and frictionally retained in adjusted position on the corresponding tubular member.
Claim 7
Dependent Claim
37 words
The combination of claim 1 wherein said stands include enlarged bases carried by their lower end portions adapted to be disposed on a suitable supporting surface and to support said stands in upright positions from said surface.
Claim 8
Dependent Claim
24 words
The combination of claim 6 wherein said bases include upstanding bores formed therethrough, and a plurality of headed anchor spikes insertable through said bores.
Claim 9
Dependent Claim
