Abstract
Abstract In exercising and in competition with another using like captive apparatus of a type having a shaft rotated by the user, performance is measured by utilizing the rotation of the shaft to effect the pumping of a predetermined volume of a fluid as one objective and, as other objectives, timing the interval required to attain that volume or to establish a time limit for operating the apparatus.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
Apparatus including a captive exercising device having a shaft rotated by the user thereof, a pump connected to said shaft, a liquid reservoir and liquid delivery means including said pump the intake of which is in communication with said reservoir, a receiver, a delivery conduit effecting communication between the discharge of said pump and the receiver, a return conduit effecting communication between the receiver and the reservoir, and valve means normally operable to prevent flow from said receiver to said reservoir, said receiver of a type measuring the pumped volume.
Claim 2
Dependent Claim
90 words
Apparatus including a captive exercising device having a shaft rotated by the user thereof, a pump connected to said shaft, a liquid reservoir and liquid delivery means including said pump the intake of which is in communication with said reservoir, a receiver, a delivery conduit effecting communication between the discharge of said pump and the receiver, a return conduit effecting communication between the receiver and the reservoir, and valve means normally operable to prevent flow from said receiver to said reservoir, said receiver of a type measuring the pumped volume.
Claim 3
Dependent Claim
42 words
The apparatus of claim 1 in which the delivery conduit includes a valve between the receiver and the pump operable to prevent return flow therethrough and the return conduit has a manually operated valve operable to block or permit return flow therethrough.
Claim 4
Dependent Claim
49 words
The apparatus of claim 1 in which the receiver includes means attached to the device and supporting the receiver in a position to be observed by the user while the device is in use and the receiver is of a type enabling the liquid level therein to be observed.
Claim 5
Dependent Claim
33 words
The apparatus of claim 3 in which the receiver is of a height sufficiently greater than the cross sectional area thereof so that the rate at which the receiver fills is readily noticeable.
Claim 6
Dependent Claim
97 words
Apparatus for use with a captive exercising device having a shaft rotated by the user thereof, said apparatus including a pump adapted to be attached to said shaft, a reservoir for a liquid, means operable to place the intake of the pump in communication with the reservoir, a receiver, a delivery conduit effecting communication between the discharge of the pump and the receiver, a return conduit effecting communication between the receiver and the reservoir, valve means normally operable to prevent return flow from the receiver, and means to attach said pump, reservoir and receiver to said device.
Claim 7
Dependent Claim
97 words
Apparatus for use with a captive exercising device having a shaft rotated by the user thereof, said apparatus including a pump adapted to be attached to said shaft, a reservoir for a liquid, means operable to place the intake of the pump in communication with the reservoir, a receiver, a delivery conduit effecting communication between the discharge of the pump and the receiver, a return conduit effecting communication between the receiver and the reservoir, valve means normally operable to prevent return flow from the receiver, and means to attach said pump, reservoir and receiver to said device.
Claim 8
Dependent Claim
40 words
The apparatus of claim 5 in which the valve means includes a valve in said delivery conduit operable to prevent return flow therethrough and a manually operable valve in the return conduit operable to block or permit return flow therethrough.
Claim 9
Dependent Claim
66 words
The apparatus of claim 5 in which the attaching means for the receiver is operable when attached to the device to support the receiver in a position to be observed by the user of the device and the receiver is of a type enabling the liquid level therein to be observed and the height of the receiver is substantially greater than the cross sectional area thereof.
