Abstract
Abstract A cable with a terminal construction to transfer a load. Load transfer parts are structurally related with resilient load carrying elements interposed to give a controlled relative movement between the transfer parts. An electrical switch is supported in the terminal and the movement is used to actuate the switch which is included in an electrical circuit to give an indication such as a light when a selected load is applied to the terminal. An adjustable screw mounted in one of the load transfer parts provides the capability of varying the actuation of the switch to obtain the particular load selection desired.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
A load supporting cable having an insulated electrical conductor embedded therein and extending therethrough, a terminal assembly constructed to transfer a load to the cable, said assembly including a. a first terminal part attached to the cable, b. an electrical switch supported in said terminal assembly and having a connection to said conductor, c. a movable actuator operatively associated with said switch, d. a second terminal part mounted with provision for axial movement with respect to said first terminal part, e. spring disc resilient means reactively interposed between said terminal parts to provide for controlled axial movement dependent on the load, f. means associated with said assembly positioned to contact said actuator and actuate said switch upon application of a predetermined load on said second part.
Claim 2
Dependent Claim
126 words
A load supporting cable having an insulated electrical conductor embedded therein and extending therethrough, a terminal assembly constructed to transfer a load to the cable, said assembly including a. a first terminal part attached to the cable, b. an electrical switch supported in said terminal assembly and having a connection to said conductor, c. a movable actuator operatively associated with said switch, d. a second terminal part mounted with provision for axial movement with respect to said first terminal part, e. spring disc resilient means reactively interposed between said terminal parts to provide for controlled axial movement dependent on the load, f. means associated with said assembly positioned to contact said actuator and actuate said switch upon application of a predetermined load on said second part.
Claim 3
Dependent Claim
36 words
A construction according to claim 1 in which an adjustable element is mounted on one of said terminal parts in position to contact said actuator to provide for adjusting the switch operation to the desired setting.
Claim 4
Dependent Claim
36 words
A construction according to claim 1 in which the means positioned to contact the actuator is a threaded element adjustable with respect to one of said terminal parts to provide the desired setting for switch actuation.
Claim 5
Dependent Claim
182 words
A load supporting cable, a pair of insulated electrical conductors embedded in said cable and extending therethrough, a terminal aSsembly constructed to transfer a load to the cable, means incorporated in said terminal assembly which respond to a particular applied load to provide an indication, said means including a. a first terminal part attached to said cable, b. a normally closed electrical switch connected to said conductors and supported on said first terminal part, said switch having an actuator extending therefrom, c. a second terminal part mounted for axial movement relative to said first terminal part, d. an element projecting from said second terminal part in position to depress said switch actuator a predetermined amount when said second terminal part is in the no-load position, e. spring disc resilient means reactively interposed between said terminal parts to provide for controlled axial movement dependent on the load, said resilient means providing for movement between said parts sufficient to allow movement of said actuator to the normally closed position upon application of the particular applied load thereby providing for completion of an indicating circuit.
Claim 6
Dependent Claim
182 words
A load supporting cable, a pair of insulated electrical conductors embedded in said cable and extending therethrough, a terminal aSsembly constructed to transfer a load to the cable, means incorporated in said terminal assembly which respond to a particular applied load to provide an indication, said means including a. a first terminal part attached to said cable, b. a normally closed electrical switch connected to said conductors and supported on said first terminal part, said switch having an actuator extending therefrom, c. a second terminal part mounted for axial movement relative to said first terminal part, d. an element projecting from said second terminal part in position to depress said switch actuator a predetermined amount when said second terminal part is in the no-load position, e. spring disc resilient means reactively interposed between said terminal parts to provide for controlled axial movement dependent on the load, said resilient means providing for movement between said parts sufficient to allow movement of said actuator to the normally closed position upon application of the particular applied load thereby providing for completion of an indicating circuit.
Claim 7
Dependent Claim
30 words
A construction according to claim 4 in which the element projecting from said second terminal part is a threaded element to provide for adjustment relative to said second terminal part.
Claim 8
Dependent Claim
25 words
A construction according to claim 4 in which the resilient means incorporate a pair of spring discs mounted with their outside diameters in opposed relationship.
Claim 9
Dependent Claim
34 words
A construction according to claim 4 in which the resilient means include two spring discs with their outer peripheries in engagement and a spacer washer is located between the discs adjacent their inner diameter.
