Abstract
Abstract A vehicle tie-dow device comprising a carriage adapted to be locked in longitudinally adjusted position on a rail extending lengthwise of the deck of a transport, such as a rail car. The carriage has a rotatable shaft upon which is wound a chain adapted to engage ad hold a vehicle. The shaft has a lug normally preventing it from being withdraw from the carriage, but the shaft may be tilted to clear the lug ad permit the shaft to be withdrawn or inserted. A ratchet gear ad pawl are provided for preventing shaft rotation in one direction. The pawl has a tab overlying the gear to prevent accidental withdrawal of the shaft when the gear is engaged by the pawl. A sprig pressed lock pin on the carriage secures the carriage to the rail.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
162 words
A carriage for use in a vehicle tie-down structure including a longitudinally extending rail adapted to be anchored lengthwise upon a longitudinally extending deck of a transport, said carriage being adapted to be carried by and locked in longitudinally adjusted position on said rail, said carriage having a frame, spaced upper and lower bearings on said frame, a generally upright shaft mounted for rotation in said bearings and adapted to have a flexible element wound thereon between said bearings to engage and hold a vehicle, ratchet gear and pawl means for preventing rotation of said shaft in one direction, and a lug on said shaft beneath said upper bearing to block upward axial withdrawal of said shaft and separation thereof from said frame, said lower bearing being relieved aT one side so that said shaft may be tilted enough to permit said lug to clear said upper bearing, whereby said shaft while thus tilted may be withdrawn upwardly through said upper bearing.
Claim 2
Dependent Claim
162 words
A carriage for use in a vehicle tie-down structure including a longitudinally extending rail adapted to be anchored lengthwise upon a longitudinally extending deck of a transport, said carriage being adapted to be carried by and locked in longitudinally adjusted position on said rail, said carriage having a frame, spaced upper and lower bearings on said frame, a generally upright shaft mounted for rotation in said bearings and adapted to have a flexible element wound thereon between said bearings to engage and hold a vehicle, ratchet gear and pawl means for preventing rotation of said shaft in one direction, and a lug on said shaft beneath said upper bearing to block upward axial withdrawal of said shaft and separation thereof from said frame, said lower bearing being relieved aT one side so that said shaft may be tilted enough to permit said lug to clear said upper bearing, whereby said shaft while thus tilted may be withdrawn upwardly through said upper bearing.
Claim 3
Dependent Claim
32 words
The carriage defined in claim 1, wherein said frame has guide means for said flexible element, said guide means being at the side of said lower bearing opposite the relieved side thereof.
Claim 4
Dependent Claim
19 words
The carriage defined in claim 2, wherein said guide means includes a tunnel at one end of said frame.
Claim 5
Dependent Claim
32 words
The carriage defined in claim 2, wherein said lower bearing is arcuate at the side opposite said relieved side, said relieved side being enlarged relative to the arc at said opposite side.
Claim 6
Dependent Claim
25 words
The carriage defined in claim 2, wherein said lower bearing is arcuate at the side opposite said relieved side, said relieved side being upwardly flared.
Claim 7
Dependent Claim
35 words
The carriage defined in claim 2, wherein said lower bearing is arcuate at the side opposite said relieved side, said relieved side being enlarged relative to the arc at said opposite side and upwardly flared.
Claim 8
Dependent Claim
83 words
The carriage defined in claim 6, wherein said ratchet and pawl means includes a gear fixed upon the upper end of said shaft above said upper bearing for rotation with said shaft, and a pawl pivotally mounted on said frame and engageable with the teeth of said gear to prevent rotation thereof in one direction, said pawl having a tab overlying said gear in the position of said pawl engaging the teeth of said gear to prevent accidental upward withdrawal of said shaft.
Claim 9
Dependent Claim
19 words
The carriage defined in claim 7, wherein said guide means includes a tunnel at one end of said frame.
Claim 10
Dependent Claim
28 words
The carriage defined in claim 1, wherein said lower bearing has an arcuate bearing surface of approximately 180* in extent at the side thereof opposite said relieved side.
Claim 11
Dependent Claim
33 words
The carriage defined in claim 1, wherein said upper bearing is large enough to accommodate said shaft and an attached flexible element when said shaft is tilted and withdrawn upwardly therethrough as aforesaid.
Claim 12
Dependent Claim
93 words
The carriage defined in claim 1, wherein said ratchet and pawl means includes a gear fixed upon the upper end of said shaft above said upper bearing for rotation with said shaft, and a pawl pivotally mounted on said frame and engageable with the teeth of said gear to prevent rotation thereof in one direction, said pawl having a tab overlying said gear when said pawl is engaged with said gear teeth and also continuously during ratchetting when said pawl passes over said gear teeth to prevent accidental upward withdrawal of said shaft.
Claim 13
Dependent Claim
196 words
A carriage for use in a vehicle tie-down structure including a longitudinally extending rail adapted to be anchored lengthwise upon a longitudinally extending deck of a transport, said carriage being adapted to be carried by and locked in longitudinally adjusted position on said rail, said carriage having a frame, spaced upper and lower bearings on said frame, a generally upright shaft mounted for rotation in said bearings and adapted to have a flexible element wound thereon to engage and hold a vehicle, ratchet gear and pawl means for preventing rotation of said shaft in one direction, a lug on said shaft engageable beneath a portion of said frame surrounding one of said bearings to normally block upward axial withdrawal of said shaft and separation thereof from said frame, the other of said bearings being relieved at one side at least 180* so that said shaft may be tilted enough to permit said lug to clear said portion of said frame, whereby said shaft while thus tilted may be withdrawn upwardly through said upper bearing, and guide means on said frame for said flexible element at the side of said other bearing opposite the relieved side thereof.
Claim 14
Dependent Claim
196 words
A carriage for use in a vehicle tie-down structure including a longitudinally extending rail adapted to be anchored lengthwise upon a longitudinally extending deck of a transport, said carriage being adapted to be carried by and locked in longitudinally adjusted position on said rail, said carriage having a frame, spaced upper and lower bearings on said frame, a generally upright shaft mounted for rotation in said bearings and adapted to have a flexible element wound thereon to engage and hold a vehicle, ratchet gear and pawl means for preventing rotation of said shaft in one direction, a lug on said shaft engageable beneath a portion of said frame surrounding one of said bearings to normally block upward axial withdrawal of said shaft and separation thereof from said frame, the other of said bearings being relieved at one side at least 180* so that said shaft may be tilted enough to permit said lug to clear said portion of said frame, whereby said shaft while thus tilted may be withdrawn upwardly through said upper bearing, and guide means on said frame for said flexible element at the side of said other bearing opposite the relieved side thereof.
