Abstract
Abstract Two or more high pressure hoses are stacked and constrained to provide a substantially unidirectional force by means of a floating spacer. The hoses are totally enclosed and operated between two predetermined contours by means of high pressure hydraulic fluid.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
In a hydraulic motor, the combination of; an upper channelled shoe comprising a heavy-walled channel iron; a lower channelled shoe comprising a second heavy-walled channel iron; means for mounting said two channel irons in spaced relationship with the respective channels therein facing each other; a floating spacer iron including an upper elongated tongue fitting and partially filling the channel in said upper shoe and a lower elongated tongue fitting and partially filling the channel in said lower shoe for maintaining said two shoes in longitudinal alignment; a pair of high pressure hoses positioned one on eacH side of said floating spacer and within one of the channels in said upper and lower shoes for actuating the motor; end fittings on said hoses for conducting hydraulic fluid into one end of each of said hoses and out of the other ends; mounting means for securing said end fittings to said shoes for confining said hoses in their longitudinal dimensions; and return spring means for returning said lower shoe and spacer toward said upper shoe in the absence of substantial hydraulic pressure in said hoses.
Claim 2
Dependent Claim
183 words
In a hydraulic motor, the combination of; an upper channelled shoe comprising a heavy-walled channel iron; a lower channelled shoe comprising a second heavy-walled channel iron; means for mounting said two channel irons in spaced relationship with the respective channels therein facing each other; a floating spacer iron including an upper elongated tongue fitting and partially filling the channel in said upper shoe and a lower elongated tongue fitting and partially filling the channel in said lower shoe for maintaining said two shoes in longitudinal alignment; a pair of high pressure hoses positioned one on eacH side of said floating spacer and within one of the channels in said upper and lower shoes for actuating the motor; end fittings on said hoses for conducting hydraulic fluid into one end of each of said hoses and out of the other ends; mounting means for securing said end fittings to said shoes for confining said hoses in their longitudinal dimensions; and return spring means for returning said lower shoe and spacer toward said upper shoe in the absence of substantial hydraulic pressure in said hoses.
Claim 3
Dependent Claim
50 words
A hydraulic motor as set forth in claim 1; wherein the inner surface of the channel in the upper shoe, and the inner surface of the lower shoe, and the two tongues are formed to provide contoured spaces between said tongues and channels in the vicinity of the ends thereof.
Claim 4
Dependent Claim
91 words
A hydraulic motor as set forth in claim 1; wherein said channels in said shoes and said tongues on said spacer are formed and adapted, when assembled with said hoses in place, to provide two contoured predetermined spaces for said hoses, a smaller space when said hoses are de-energized and a larger space when said hoses are under working hydraulic pressure, and wherein said smaller space provides for the hoses to be in contoured semi-distended condition and said larger space defines the maximum distended contour permitted at the full work stroke.
Claim 5
Dependent Claim
43 words
A hydraulic motor as set forth in claim 1; wherein said upper and lower shoes in combination with said spacer and said end fitting mountings provide totally enclosed compartments for said hoses when the motor is both in the neutral and expanded positions.
Claim 6
Dependent Claim
39 words
A hydraulic motor as set forth in claim 1, and including: a plurality of bolts surrounded by cylindrical ball bushings passing through holes in said upper and lower shoes and said spacer for further aligning said shoes and spacer.
Claim 7
Dependent Claim
34 words
A hydraulic motor as set forth in claim 1, and including; means for limiting the maximum and minimum expansion positions of said hoses to limit the bending of the hose casings to predetermined contours.
