Abstract
Abstract An overload stop for a transducer. A pin extends through and is spaced from an aperture in a load-deflectable element thereby limiting the travel of the deflectable element to the adjusted clearance between the pin and the sides of the aperture.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
In a load-sensing transducer having an element deflectable by forces being sensed by said transducer, and a fixed element, the improvement whereby said deflectable element comprises an elongate aperture formed therein which extends normal to the direction of said deflection; an elongate stop-pin member affixed to said fixed element and extending into said elongate aperture; the stop-pin so spaced from the wall of said aperture to determine a deflection limit for said deflectable element of the transducer; and adjusting means, carried within said deflectable element, to adjust the space between said deflectable element and said stop-pin; said adjusting means being so arranged to enable the adjustment to be carried out from outside the transducer.
Claim 2
Dependent Claim
114 words
In a load-sensing transducer having an element deflectable by forces being sensed by said transducer, and a fixed element, the improvement whereby said deflectable element comprises an elongate aperture formed therein which extends normal to the direction of said deflection; an elongate stop-pin member affixed to said fixed element and extending into said elongate aperture; the stop-pin so spaced from the wall of said aperture to determine a deflection limit for said deflectable element of the transducer; and adjusting means, carried within said deflectable element, to adjust the space between said deflectable element and said stop-pin; said adjusting means being so arranged to enable the adjustment to be carried out from outside the transducer.
Claim 3
Dependent Claim
87 words
The transducer of claim 1 wherein A. said means for adjusting said space comprises a threaded bore in said deflectable element, said bore extending toward said aperture, thereby defining a relatively thin web between said bore and said aperture, said web engaging said stop pin when the allowable deflection of said transducer is reached, and B. an adjusting screw threaded in said bore, whereby said screw may be turned in toward said web to distend said web and reduce the clearance between said web and said stop-pin.
Claim 4
Dependent Claim
28 words
The transducer of claim 1 wherein said elongate stop-pin has a first tapered portion proximate one end thereof fit into a tapered receptacle formed in said fixed element.
Claim 5
Dependent Claim
46 words
The transducer of claim 3 wherein said pin is generally tapered and has a reduced section which extends into said elongate aperture, whereby the clearance between said reduced section and the wall of said aperture determines said deflection limit for said deflectable element of the transducer.
Claim 6
Dependent Claim
36 words
The transducer defined in claim 3 wherein said pin further comprises a second tapered portion proximate the other end thereof, said first and second tapered portions being fit into axially spaced segments of said tapered receptacle.
