Abstract
Abstract An apparatus is disclosed comprising a U-shaped channel with fulcrum ledges running the length of same, which is engaged about a bent splicing sleeve, and a lever cam with handle, with which a straightening force is applied. The lever cam, when inserted into the channel, cooperates with the fulcrum ledges in transmitting a straightening force applied to the splicing sleeve.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
203 words
Apparatus for straightening an elongated ductile object, comprising: a. a generally U-shaped channel having an open top for receiving therein a bent portion of said object through said open top; b. said channel having a generally flat bottom surface; c. the lateral sides of said channel having along their tops inwardly extending ledges provided with downward fulcrum surfaces; d. a cooperating lever cam having an arcuate camming surface engageable with said object; e. oppositely extending lateral pins on said lever cam engageable respectively with said fulcrum surfaces; f. an operating handle on said cam extending perpendicularly to said pins; g. said channel and said cam cooperating in such manner that when said object is engaged in said channel with a portion thereof spaced from the channel bottom, said cam is insertable in an end of the channel with its handle extending outwardly thereof, its pins engaging said fulcrum surfaces and its camming surface engaging said object at said portion spaced from said channel bottom and on the side away therefrom; and h. whereby rotation of said handle on an axis transverse to said channel will cause said cam to press said portion of said object toward said channel bottom to straighten said object.

Apparatus for straightening an elongated ductile object, comprising: a. a generally U-shaped channel having an open top for receiving therein a bent portion of said object through said open top; b. said channel having a generally flat bottom surface; c. the lateral sides of said channel having along their tops inwardly extending ledges provided with downward fulcrum surfaces; d. a cooperating lever cam having an arcuate camming surface engageable with said object; e. oppositely extending lateral pins on said lever cam engageable respectively with said fulcrum surfaces; f. an operating handle on said cam extending perpendicularly to said pins; g. said channel and said cam cooperating in such manner that when said object is engaged in said channel with a portion thereof spaced from the channel bottom, said cam is insertable in an end of the channel with its handle extending outwardly thereof, its pins engaging said fulcrum surfaces and its camming surface engaging said object at said portion spaced from said channel bottom and on the side away therefrom; and h. whereby rotation of said handle on an axis transverse to said channel will cause said cam to press said portion of said object toward said channel bottom to straighten said object.
Claim 3
Dependent Claim
25 words
The apparatus according to claim 1 wherein said object is of generally circular transverse shape and is longitudinally curved; and a. said cam surface has:
Claim 4
Dependent Claim
27 words
a concave transverse shape for transversely generally engaging said object, b. whereby to distribute the cam pressure over a substantial portion of the surface of said object.
Claim 5
Dependent Claim
27 words
a concave transverse shape for transversely generally engaging said object, b. whereby to distribute the cam pressure over a substantial portion of the surface of said object.
Claim 6
Dependent Claim
13 words
opposed laterally protruding pins extending under and engageable with said fulcrum surfaces; and
Claim 7
Dependent Claim
13 words
opposed laterally protruding pins extending under and engageable with said fulcrum surfaces; and
Claim 8
Dependent Claim
164 words
a handle perpendicular to said pins, in such manner that said arcuate surfaces engage said sleeve, said pins engage said fulcrum surfaces and said handle extends outwardly of said channel; c. rotating said cam in a longitudinal plane until said sleeve is gripped tightly enough between said cam and said channel so that said channel, said cam, said sleeve and the portions of the conductor adjacent each end thereof can be rotated as a unit in a transverse plane against the reaction of the conductor without slippage of said channel about said sleeve; d. rotating said handle in said transverse plane until said handle is in a convenient position for further rotating said cam in said longitudinal plane to increase the pressure on said sleeve; e. forcefully further rotating said cam in said longitudinal plane to deform said sleeve toward the bottom of said channel; and f. reversing the rotation of the handle in the longitudinal plane to release the grip on said sleeve.
Claim 9
Dependent Claim
164 words
a handle perpendicular to said pins, in such manner that said arcuate surfaces engage said sleeve, said pins engage said fulcrum surfaces and said handle extends outwardly of said channel; c. rotating said cam in a longitudinal plane until said sleeve is gripped tightly enough between said cam and said channel so that said channel, said cam, said sleeve and the portions of the conductor adjacent each end thereof can be rotated as a unit in a transverse plane against the reaction of the conductor without slippage of said channel about said sleeve; d. rotating said handle in said transverse plane until said handle is in a convenient position for further rotating said cam in said longitudinal plane to increase the pressure on said sleeve; e. forcefully further rotating said cam in said longitudinal plane to deform said sleeve toward the bottom of said channel; and f. reversing the rotation of the handle in the longitudinal plane to release the grip on said sleeve.
Claim 10
Dependent Claim
41 words
The apparatus according to claim 2 wherein the bottom of said channel is longitudinally grooved for general engagement with the contiguous surface of said object, whereby to distribute the reaction pressure from said channel over the contiguous surface of said object.
Claim 11
Independent Claim
113 words
The method of straightening a curved splicing sleeve in an aerial conductor which comprises: a. placing about said sleeve a generally flat-bottomed open-top U-shaped channel which subtends at least a substantial portion of said sleeve, the sleeve curvature being convex with respect to the bottom of said channel and in such transverse orientation therewith that the plane of said curvature is perpendicular to the bottom of said channel, and the lateral sides of said channel having along their tops inwardly extending ledges provided with downward fulcrum surfaces; b. inserting in an end of said channel and over said sleeve a cam having: l. an arcuate surface conformable to and engageable with said sleeve;
Claim 12
Independent Claim

Claim 13
Dependent Claim
42 words
The method set forth in claim 4 including the steps of: a. inserting said cam farther into said channel to engage a new curved portion of said sleeve; and b. repeating the deforming operation at said new curved portion of said sleeve.
