Abstract
Abstract A measuring device comprises a plate on which is mounted a digital counter, a pulley driving the counter, and a reel on which is wound a line. The line terminates in a coupling member engageable with a coupling member at the end of another line. The other line is entrained over sheaves carried by a framework on a silo. A weighted bell is attached to the other line and is suspended over material in the silo. A bracket on the side of the silo engages the other coupling member. A plurality of other lines and coupling members entrained over other adjacent silos can be provided. A bracket on a support for the plate will engage the other coupling members so that any one can be selected for engaging the first coupling member. The plate can be detachable mounted on the support for removal and mounting on another remote support.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
227 words
A level measuring device for a container of bulk material, comprising a plate mountable at a side of the container; a digital counter on said plate; a pulley carried by the plate and operatively engaged with the counter for progressively advancing digit indicators thereof when the pulley is turned; a reel rotatably carried by the plate; a first line wound on the reel and entrained on said pulley, said line being unwindable when the reel is turned; a first coupling member on the free end of the line quickly engageable with another coupling member at the end of another line entrained over said container for measuring the depth of material in the container; a weighted bell; another line engaged at one end thereof with said bell; a framework mounted on top of said container and carrying a sheave; said other line being entrained over the sheave and suspending said bell over material in the container; another coupling member at the other end of the line; and a bracket on said side of the container engaging said other coupling member to hold the bell suspended over said material, whereby the first and other coupling members can be mutually engaged and the reel can be turned to unwind the first line while the pulley turns and the counter indicates digitally the length of the first line passing the counter.
Claim 2
Dependent Claim
227 words
A level measuring device for a container of bulk material, comprising a plate mountable at a side of the container; a digital counter on said plate; a pulley carried by the plate and operatively engaged with the counter for progressively advancing digit indicators thereof when the pulley is turned; a reel rotatably carried by the plate; a first line wound on the reel and entrained on said pulley, said line being unwindable when the reel is turned; a first coupling member on the free end of the line quickly engageable with another coupling member at the end of another line entrained over said container for measuring the depth of material in the container; a weighted bell; another line engaged at one end thereof with said bell; a framework mounted on top of said container and carrying a sheave; said other line being entrained over the sheave and suspending said bell over material in the container; another coupling member at the other end of the line; and a bracket on said side of the container engaging said other coupling member to hold the bell suspended over said material, whereby the first and other coupling members can be mutually engaged and the reel can be turned to unwind the first line while the pulley turns and the counter indicates digitally the length of the first line passing the counter.
Claim 3
Dependent Claim
26 words
A level measuring device as defined in claim 1, wherein said reel is disposed to turn in a plane parallel to the plane of saiD plate.
Claim 4
Dependent Claim
26 words
A level measuring device as defined in claim 1, wherein said reel is disposed to turn in a plane perpendicular to the plane of said plate.
Claim 5
Dependent Claim
51 words
A level measuring device as defined in claim 1, further comprising another plate attachable to a support; and means for engaging the first named plate on said other plate, whereby the first named plate can be detached from said other plate while the first named plate remains attached to said support.
Claim 6
Dependent Claim
56 words
A level measuring device as defined in claim 1, further comprising further plates secured to opposite lateral edges of the first named plate so that said first plate is disposed angularly to said other plate, said reel being mounted on said first plate to rotate in a plane perpendicular to the plane of the first plate.
Claim 7
Dependent Claim
28 words
A level measuring device as defined in claim 1, further comprising releasable stop means engageable with said reel to prevent turning the reel and unwinding the first line.
Claim 8
Dependent Claim
141 words
A level measuring device as defined in claim 1, further comprising a plurality of weighted bells; a plurality of other lines each engaged at one end thereof with one of said bells; a plurality of frameworks each mounted on top of a different container; a plurality of sheaves carried by the respective frameworks; each of said other lines being entrained on the sheaves of at least one framework with each one of the bells suspended over a different one of the containers; a plurality of other coupling members being releasable engaged on said bracket for selectively engaging said first coupling member, whereby the reel can be turned to unwind the first line while the bell of a selected line descends in a selected container and the pulley turns the counter to indicate digitally the length of first line passing the counter.
Claim 9
Dependent Claim
26 words
A level measuring device as defined in claim 7, wherein said reel is disposed to turn in a plane parallel to the plane of said plate.
Claim 10
Dependent Claim
51 words
A level measuring device as defined in claim 7, further comprising another plate attachable to a support; and means for engaging the first named plate on said other plate, whereby the first named plate can be detached from said other plate while the first named plate remains attached to said support.
