Abstract
Abstract Apparatus for measuring the velocity of flow of a fluid. The apparatus is an extremely simple, lightweight, low-cost item comprising a frame formed from a single strip of sheet material, a vane hingedly connected in pendulum fashion to the frame and responsive to the rate of flow of the fluid for movement to a position corresponding to the velocity of flow of the fluid. Indicia are located on the frame to indicate the rate of flow of the fluid. Adjustment means are provided for altering the shape of the frame a limited extent so as to set the static position of the vane at a zero position on the indicia. The apparatus can be mounted in a variety of positions for the purpose of measuring the rate of flow of the fluid.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
59 words
A velocity meter for measuring the velocity of flow of fluid comprising a frame having a calibrated surface with a longitudinal slot, and a vane of thin gage material throughout its length supported by said frame for movement in said slot relative to said calibrated surface as a function of the velocity of flow of fluid against said vane.
Claim 2
Dependent Claim
59 words
A velocity meter for measuring the velocity of flow of fluid comprising a frame having a calibrated surface with a longitudinal slot, and a vane of thin gage material throughout its length supported by said frame for movement in said slot relative to said calibrated surface as a function of the velocity of flow of fluid against said vane.
Claim 3
Dependent Claim
47 words
The velocity meter that is defined by claim 1, wherein said vane is hingedly suspended as a pendulum from one portion of said frame, and said calibrated surface is on another portion of said frame adjacent to the path of free movement of said hingedly suspended vane.
Claim 4
Dependent Claim
31 words
The velocity meter that is defined in claim 2, wherein adjustment means are provided for selectively setting the position of the calibrated surface relative to the static position of said vane.
Claim 5
Dependent Claim
118 words
The velocity meter for measuring the velocity of flow of fluid comprising a frame having a calibrated surface, and a vane supported by said frame for movement relative to said calibrated surface as a function of the velocity of flow of fluid against said vane, said frame having a Z-shaped sheet portion providing a lower horizontal leg, an upper horizontal leg and an inclined intermediate leg joined at its lower end to the lower leg and at its upper end to the upper leg, said inclined intermediate leg having a longitudinal slot adjacent to which said calibrated surface is located, said vane being hingedly supported from the distal end of said upper leg and extending into said slot.
Claim 6
Dependent Claim
118 words
The velocity meter for measuring the velocity of flow of fluid comprising a frame having a calibrated surface, and a vane supported by said frame for movement relative to said calibrated surface as a function of the velocity of flow of fluid against said vane, said frame having a Z-shaped sheet portion providing a lower horizontal leg, an upper horizontal leg and an inclined intermediate leg joined at its lower end to the lower leg and at its upper end to the upper leg, said inclined intermediate leg having a longitudinal slot adjacent to which said calibrated surface is located, said vane being hingedly supported from the distal end of said upper leg and extending into said slot.
Claim 7
Dependent Claim
60 words
The velocity meter that is defined in claim 4, wherein an adjustment rod is threadedly connected to one of said legs and is adapted when turned to exert a thrust against a supporting surface for the velocity meter so as to deflect said frame for setting the position of said calibrated surface relative to the static position of said vane.
Claim 8
Dependent Claim
29 words
The velocity meter that is defined in claim 4, wherein one of said horizontal legs has a return bent bracket portion for mounting the meter on a supporting surface.
Claim 9
Dependent Claim
41 words
The velocity meter that is defined in claim 6, wherein a vertical adjustment rod is threadedly connected to said one horizontal leg and is axially movable when turned for engagement with either said bracket or the other of said horizontal legs.
Claim 10
Dependent Claim
176 words
A velocity meter for measuring the velocity of flow of fluid comprising a frame formed from a strip of resilient sheet material to define a Z-shaped portion with upper and lower horizontal legs joined by an inclined intermediate leg and a bracket portion extending from the end of one of said legs in a reverse direction, said intermediate leg having a longitudinal slot, a vane hingedly suspended on a transverse axis from the upper horizontal leg so as to extend into said slot for free movement therein to a predetermined location in response to flow of fluid of predetermined velocity through said slot, said intermediate leg having a calibrated surface adjacent to said slot to indicate the velocity of flow corresponding to the position of said vane, and at least one adjustment rod threadedly connected to said one horizontal leg and axially movable when turned for engagement with either said bracket portion or the other of said horizontal legs for selectively setting the position of the calibrated surface relative to the static position of said vane.
Claim 11
Dependent Claim
176 words
A velocity meter for measuring the velocity of flow of fluid comprising a frame formed from a strip of resilient sheet material to define a Z-shaped portion with upper and lower horizontal legs joined by an inclined intermediate leg and a bracket portion extending from the end of one of said legs in a reverse direction, said intermediate leg having a longitudinal slot, a vane hingedly suspended on a transverse axis from the upper horizontal leg so as to extend into said slot for free movement therein to a predetermined location in response to flow of fluid of predetermined velocity through said slot, said intermediate leg having a calibrated surface adjacent to said slot to indicate the velocity of flow corresponding to the position of said vane, and at least one adjustment rod threadedly connected to said one horizontal leg and axially movable when turned for engagement with either said bracket portion or the other of said horizontal legs for selectively setting the position of the calibrated surface relative to the static position of said vane.
Claim 12
Dependent Claim
63 words
The velocity meter that is defined in claim 8, wherein two adjustment rOds are threadedly connected to said horizontal leg adjacent to opposite sides of said frame, and said bracket portion and said other horizontal leg have dimples formed therein for receiving the ends of said rods to maintain the latter in vertical alignment when the rods are moved axially for adjustment purposes.
Claim 13
Dependent Claim
20 words
The velocity meter that is defined in claim 8, wherein said frame is formed from a strip of stainless steel.
