Abstract
Abstract The two warp beams are each connected to different bevel gears in the transmission. These bevel gears are in meshing engagement with two planet pinions mounted in a freely mounted carrier. The carrier is, in turn, mounted in diametrically opposite slots in a driving wheel for the transmission. The driving wheel is driven over a worm. Any variation in speed between the warp beams causes the planet pinions to turn relative to the bevel gears to compensate for the variation without overstressing the gears.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
120 words
A differential gear comprising a driving wheel having a pair of diametrically opposite guides therein, each guide having guideways extending transversely of the axis of said wheel, a rotatable shaft mounted coaxially of said driving wheel, a pair of bevel gears mounted on said shaft coaxially of said axis of said driving wheel, means securing said bevel gears in axial relation to each other on said shaft, at least two planEt bevel pinions in meshing engagement with and between said bevel gears, a common carrier mounting said pinions coaxially thereon, said carrier being displaceably mounted in a radial direction and axially in said guides of said driving wheel, and a thrust bearing means between each planet pinion and said carrier.
Claim 2
Dependent Claim
120 words
A differential gear comprising a driving wheel having a pair of diametrically opposite guides therein, each guide having guideways extending transversely of the axis of said wheel, a rotatable shaft mounted coaxially of said driving wheel, a pair of bevel gears mounted on said shaft coaxially of said axis of said driving wheel, means securing said bevel gears in axial relation to each other on said shaft, at least two planEt bevel pinions in meshing engagement with and between said bevel gears, a common carrier mounting said pinions coaxially thereon, said carrier being displaceably mounted in a radial direction and axially in said guides of said driving wheel, and a thrust bearing means between each planet pinion and said carrier.
Claim 3
Dependent Claim
52 words
A differential gear as set forth in claim 1 wherein said guideways of each guide are parallel to a radial plane of said driving wheel to define a slot-like recess and said carrier has projecting studs disposed within each recess for movement of said carrier axially and radially of said driving wheel.
Claim 4
Dependent Claim
37 words
In combination with a differential gear as set forth in claim 1, a casing mounting said gear therein and a pinion journalled in said casing in meshing engagement with said driving wheel for rotating said driving wheel.
Claim 5
Dependent Claim
45 words
The combination as set forth in claim 3 further comprising a pair of pinions journalled in said casing in driving connection with a respective one of said bevel gears, a pair of transmissions, each said transmission being connected to a respective one of said pinions.
Claim 6
Dependent Claim
20 words
A differential gear as set forth in claim 1 wherein each thrust bearing means is adjustably mounted on said carrier.
