Abstract
Abstract A device for mixing paint and similar thick liquids within a container in which the container is held between the jaws of a clamp and rocked back and forth by a source of power. The clamp jaws are freely mounted so that they can rotate with the container about its longitudinal axis. An inertially driven mechanism which is independent of the rocking power source serves to rotate the container about its longitudinal axis as it is rocked, thereby greatly reducing the time required to thoroughly mix the paint within the container.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
A container clamping and rotating apparatus for a liquid mixing machine having an oscillating power output source comprising a clamp coupled to the oscillating power source, spaced container grasping jaws on said clamp, a first and a second container support plate freely journaled on the spaced jaws, inertial drive means carried by the clamp and operatively coupled to at least one of the container support plates to rotate the container within the jaws as the clamp is being oscillated and means to move the jaws toward and away from each other to grasp and release the container.
Claim 2
Dependent Claim
97 words
A container clamping and rotating apparatus for a liquid mixing machine having an oscillating power output source comprising a clamp coupled to the oscillating power source, spaced container grasping jaws on said clamp, a first and a second container support plate freely journaled on the spaced jaws, inertial drive means carried by the clamp and operatively coupled to at least one of the container support plates to rotate the container within the jaws as the clamp is being oscillated and means to move the jaws toward and away from each other to grasp and release the container.
Claim 3
Dependent Claim
68 words
Apparatus according to claim 1 in which the clamp is coupled to the oscillating power source by a plate-like adaptor having spaced transverse bores therein, an elongated guide rod received in each of the transverse bores and secured to the adaptor intermediate the free ends of the guide rods, and spaced transverse bores in each of the jaws to slidably receive the free ends of the guide rods.
Claim 4
Dependent Claim
70 words
Apparatus according to claim 2 in which the adaptor is formed with a transverse bore between the spaced transverse bores therein, an elongated adjusting screw is freely received within the said bore, said adjusting screw having a right hand thread for a portion of its length on one side of the adaptor and a left hand thread for a portion of its length on the other side of the adaptor.
Claim 5
Dependent Claim
48 words
Apparatus according to claim 3 in which the container grasping jaws are transversely bored and threaded to receive the left and right hand threaded portions of the adjusting screw and handle means are carried by the said adjusting screw to control the position of the container grasping jaws.
Claim 6
Dependent Claim
15 words
Apparatus according to claim 1 in which the inertial drive means is a one-way clutch.
Claim 7
Dependent Claim
37 words
Apparatus according to claim 5 in which the one-way clutch is driven by a lever coupled to the clutch and a weighted portion at the free end of said lever responsive to the oscillation of the clamp.
Claim 8
Dependent Claim
54 words
Apparatus according to claim 6 in which the inertial drive means lever is formed with a transverse bore opposite the weighted portion, said transverse bore being received upon a hub carried by one of the jaws, and a plurality of pin bearings between the transverse bore and the hub, forming a one-way clutch mechanism.
Claim 9
Dependent Claim
34 words
Apparatus according to claim 1 in which the inertial drive means is a ratchet mechanism driven by a lever coupled to the clutch, said lever having a weighted portion at the free end thereof.
Claim 10
Dependent Claim
47 words
Apparatus according to claim 1 in which the first and second container support plates are coupled to said jaws by a hub freely carried by a bearing in each of said container supports, and the inertial drive means is coupled to at least one of said hubs.
