SUMMARY OF THE INVENTION
The present invention relates to a rnechanism for detecting flow in a fluid carrying conduit which, in yeneral, comprises a saddle adapted for securement tothe conduit in overlying relationship to an opening to the conduit, an adapter plate for providing a sealing relation between the saddle and the conduit and flow detecting means adapted for insertion in the conduit and shiftable in response to fluid flow therethrough including a reactor member extending into the saddle. - -BACKGROUND OF THE INVENTION
The present invention pertains to a flow detecting mechanism and, moreparticularly, to a flow detecting mechanism useful for operating other mechani SltlS such as a switch.
Flow detecting mechanisms of the type referred to have many varied applications for sensing and controlling flow in fluid carrying apparatus as well as operating associated structure in response to the presence or absence offluid flow. Many such mechanisms now available sense fluid flow by movement of a vane or like detector disposed in a fluid carrying conduit. Physical movementof the detector is accomplished either directly by fluid flow impinging thereon or by use of structure such as orifices, blades or turbines in the conduit that creates a pressure differential which causes shifting of the detector. This physical movement must then be transmitted externally of the conduit to operate a switch, usually electrical, to indicate the presence of flow.
A typical example of such flow detecting mechanisms is that described in U.
S. 4,454,768 issued June 19, 1984. As is typical of such devices described in this patent, the housing or saddle which carries the actuator means is secured directly to the fluid carrying conduit at an opening in the wall of the conduit.Naturally, the connection must be made in a tight sealing relationship.
OBJECTS OR FEATURES OF T~IE INVENTION
Accordingly, it is a feature of the present invention to provide a fluid flow detector assembly wherein the saddle of the assembly is secured to a conduit through an adapter. Another feature of the invention is the pro~ision 39~ii of such an assembly wherein the saddle includes boss means adapted to engage the conduit at its opening.
According to the above features, from a broad aspect, the present invention provides a fluid flow detector assembly comprising a saddle having a first opening and adapted for securement to a conduit having a second opening.
A curved adaptor plate is provided between the saddle and the conduit in sea]ing relation and has a third opening.
The first, second and third openings are in alignment with one another. A first boss means extends from the curved adaptor plate, around the third opening, and engaging the saddle in the second opening. A second boss means, in-cluding flexible fingers, extends from the saddle around the first opening and engages the conduit in the second opening to provide a seal between the saddle and the conduit. Flow detection means is adapted fo~ insertion in the conduit through the first, second and third openings. A portion of the flow detection means is in contact with the flexible fingers to force the fingers into contact with the conduit.
The flow detection means is shiftable in response to fluid flow through the conduit and including a reactor member extending into the saddle.
These and other features of the invention will become apparent from the following description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAr~INGS
Referring now to the drawings, there is shown a flow detecting mechanism 10 which is enclosed in a housing or saddle 12 that is adapted to be connected to an opening 14 of conduit 16. The saddle 12 is comprised of a cup-shaped member 20 having an open end 22 and a base 24 having opening 26 therein. The opening 22 is closed by a resilient member 28 which forms a tight seal with the housing. A
rigid plate 30 holds seal 28 and backup plate 32 in place.
A flow detection means 34 responds to fluid flow in conduit 16. Detecting means 34 includes a reactor member 36 and an actuator means 38. Reactor member 36 includes a shart 40 and a rigid arm 42 which is fixed -to the shaft.
Shaft 40 extends through apertures 44 of plate 30 and 46 of backup plate 32 and is held in a seal tight relation with resilient member 28. Shaft 40 is made to pivot about point 48 through the pivoting of the distal ends 42' and 42"
engaging grooves in backup plate 32.
Actuator means 38 includes a paddle 50 that is carried in conduit 16 and is pivotally mounted on pin 52 through coil springs 54 and 56. More specifically, the distal ends 54' and 56' are connected to the paddle 50. The reactor member and the actuator means are pivotally con-nected together through the other ends - 2a-.6~
54" and 56" being connected to or engaged with a sleeve 58 carried on the arm 42of the reactor member.
In accordance with the present invention, saddle 12 is held in a sealing tight relationship through an adapter 60 which is fabricated from an elastomer that is substantially impervious to water. As best shown in Figures 3 and 4, the adapter, in the illustrative embodiment, is a semi-circular plate that is shaped to fit conduit 14 for which it is being used. The adapter includes an aperture 62 which is placed in line with opening 14 of conduit 16. In order to further provide a tight seal around the opening, the adapter further includes a boss 64 surrounding aperture 62. As shown in Figure 1, the adapted is squeezed between the conduit and the saddle by having a plurality of bolts 66 or other fastening means connect the saddle to a bracket 70 which extends around the conduit where the flow detector is to be located.
A further seal is also provided by boss means 76 extending from saddle 12.
8Oss means 12 includes two sets of oppositely disposed fingers 72 and 74 which carries pin 52. When pin 52 is inserted between the fingers they are forced apart to provide a tight fit with the fingers.
In operation, and referring in particular to Figure 2, with a fluid flow in the direction indicated by the arrow, paddle 50 is forced counterclockwise aboutthe pin 52 which in turn pivots arm 42 and thus shaft 40 in a clockwise direction to close a switch means 60. When fluid flow in the conduit stops, there being no force acting on paddle 50, spring 62 causes shaft 48 to pivot counterclockwise to open the switch 60 and return the paddle 50 to its l'at rest"
position 64 throush the coil springs 54 and 56. The fact that the actuator means and the reactor member both have a pivot point requires less force to openthe switch 60.
Figure 2 is a view similar to Figure 1 showing another side elevation of the mechanism in conjunction with the conduit.
Figure 3 is an isometric view of an adapter.
Figure 4 is an isometric view of a conduit to which the fluid detector assembly is connected.
