Abstract
Abstract There is described herein a pleated carriage longitudinally extensible along and guidable by a tracking means and adapted to convey in conduit and other pleated paths therealong flowable energy sources to reciprocating machines. The longitudinally extensible pleated carriage comprises for consecutive carriage pleats a transversely extending shoulder member together with a pair of transversely separated elongate upright legs that have a longitudinally spreadable relationship with respect to each other and to the shoulder, consecutive pleats remote of the shoulder and at opposite legs being connected with a transversely extending bridge member; when flexible conduits are employed, there are means to protect them from pinching, kinking, or undue strain as the carriage is longitudinally extended and retracted.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
264 words
A pleated extensible carriage adaptable for supporting at least one conduit therealong, said carriage being adapted to be employed in combination with and reciprocatably along an elongate tracking means therefor, the conduit extending in pleated fashion along and co-movable with the pleated carriage structure and having an inlet rear-end and an outlet front-end, the pleated carriage structure having a selectable relatively collapsed compact-station along a given finite-length of the tracking means whereat the respective carriage pleats are spaced relatively close together, said carriage structure commencing from a said compact-station thereof being forwardly longitudinally extensible along the tracking means whereby the respective pleats become spaced progressively far apart, said pleated extensible carriage structure at a compact-station thereof comprising: A. A plurality of shoulder members respectively extending transversely of the tracking means of the tracking means and being longitudinally reciprocatably movable therealong; B. Consecutively positioned carriage pleats comprising a said shoulder member together with a pair of elongate legs including a first-leg and a second-leg, each of said legs being attached to and extending uprightly from transversely separated locations of the shoulder whereby there is a transversely extending given-breadth between intra-pleat legs and the intrapleat legs have portions more remote from the said intra-pleat shoulder, there being a longitudinally spreadable relationship between intra-pleat legs the longitudinal degree of which becomes progressively greater toward the legs remote ends; and C. Inter-pleats bridges located remote from the respective shoulders and extending transversely from the first-leg to the second-leg of consecutive pleats, the longitudinal distance between consecutive bridges becoming greater as the intra-pleat legs become increasingly relatively spread apart.

A pleated extensible carriage adaptable for supporting at least one conduit therealong, said carriage being adapted to be employed in combination with and reciprocatably along an elongate tracking means therefor, the conduit extending in pleated fashion along and co-movable with the pleated carriage structure and having an inlet rear-end and an outlet front-end, the pleated carriage structure having a selectable relatively collapsed compact-station along a given finite-length of the tracking means whereat the respective carriage pleats are spaced relatively close together, said carriage structure commencing from a said compact-station thereof being forwardly longitudinally extensible along the tracking means whereby the respective pleats become spaced progressively far apart, said pleated extensible carriage structure at a compact-station thereof comprising: A. A plurality of shoulder members respectively extending transversely of the tracking means of the tracking means and being longitudinally reciprocatably movable therealong; B. Consecutively positioned carriage pleats comprising a said shoulder member together with a pair of elongate legs including a first-leg and a second-leg, each of said legs being attached to and extending uprightly from transversely separated locations of the shoulder whereby there is a transversely extending given-breadth between intra-pleat legs and the intrapleat legs have portions more remote from the said intra-pleat shoulder, there being a longitudinally spreadable relationship between intra-pleat legs the longitudinal degree of which becomes progressively greater toward the legs remote ends; and C. Inter-pleats bridges located remote from the respective shoulders and extending transversely from the first-leg to the second-leg of consecutive pleats, the longitudinal distance between consecutive bridges becoming greater as the intra-pleat legs become increasingly relatively spread apart.
Claim 3
Dependent Claim
95 words
The pleated extensible carriage of claim 1 wherein the several transversely extending shoulders at a carriage compact-station are substantially parallel to each other and at substantially constant elevation, the shoulders of consecutive carriage pleats and the inter-pleats bridges intersecting a common vertical-plane; and wherein the several upright first-legs and second-legs of consecutive pleats have a leg-length bearing a ratio of at least two with respect to the shoulder given-breadth, the intra-pleat legs being located and remaining on opposite transverse sides of said vertical-plane whereby a pleated conduit along each carriage pleat transversely intersects said vertical-plane.
Claim 4
Dependent Claim
121 words
The pleated extensible carriage of claim 2 wherein the transversely extending shoulder member of consecutive carriage pleats is suspended by an upright hanger from the tracking means and the shoulder member is sufficiently structurally rigid to support the entire carriage pleat and the two inter-pleats bridges; wherein both of the intra-pleat legs of consecutive carriage pleats are linear structural members that depend from and are pivotably associated with the shoulder on opposite trAnsverse sides of the hanger whereby the first-leg and second-leg of the same carriage pleat are adapted to be pivotably spread in opposite longitudinal directions from the same transversely extending shoulder; and wherein the first-leg and the second-leg of consecutive carriage pleats are pivotably associated at the inter-pleats bridge.
Claim 5
Dependent Claim
45 words
The pleated extensible carriage of claim 2 wherein the two intra-pleat legs of respective carriage pleats are substantially rigid linear members that remain in planes parallel to and located on opposite transverse sides of said vertical-plane as the carriage is being longitudinally extended and retracted.
Claim 6
Dependent Claim
41 words
The pleated extensible carriage of claim 2 wherein the shoulder and the two legs of respective consecutive carriage pleats and the inter-pleats bridges are provided of communicating tubular members whereby the carriage tubular structural members themselves additionally provide a pleated conduit.
Claim 7
Dependent Claim
46 words
The pleated extensible carriage of claim 5 wherein the two intra-pleat legs of respective carriage pleats are substantially rigid linear tubular members that remain in planes parallel to and located on opposite transverse sides of said vertical-plane as the carriage is being longitudinally extended and retracted.
Claim 8
Dependent Claim
119 words
The pleated extensible carriage of claim 6 wherein the two tubular intra-pleat legs of respective carriage pleats depend from the tubular shoulder member, at least one of the two intra-pleat legs of consecutive carriage pleats being pivotably associated with the shoulder and being of substantially like leg-length whereby the consecutive inter-pleats bridges are located at substantially common elevation, said bridges being at a higher common elevation when the carriage through said pivotal legs is longitudinally extended from a compact-station; and wherein the transversely extending shoulder member of consecutive carriage pleats is suspended by an upright hanger from the tracking means and the shoulder member is sufficiently structurally rigid to support the entire carriage pleat and the two inter-pleats bridges.
Claim 9
Dependent Claim

The pleated extensible carriage of claim 7 wherein both of the intra-pleat legs of consecutive carriage pleats are pivotably associated with the shoulder on opposite transverse sides of the hanger whereby both intra-pleat legs are adapted to be spread pivotably in opposite longitudinal directions from the same transversely extending shoulder; and wherein the first-leg and the second-leg of consecutive carriage pleats are also pivotably associated at the inter-pleats bridge.
Claim 10
Dependent Claim
