DEFINITION

Classification: 269/37

(under the class definition) Device including at least two separate holding means each of which separately immobilizes at least one workpiece with respect to another workpiece separately held by another such holding means.

(1) Note. The holding elements are separate to the extent that at least two workpieces can be maintained in position without requiring either the presence of other workpieces or the presence of the other of said two workpieces.

(2) Note. A patent claiming the use of a single pair of jaws, the work engaging faces of which are configured to enable the simultaneous grasping of separate workpieces, to hold plural workpieces relative to each other will not be placed in this subclasses (37+). Such jaws do not constitute "separate holding means" as defined above and placement will be in the appropriate subclass lower in the class schedule.

(3) Note. A patent claiming the use of plural work contacting elements to hold workpieces relative to each other but which elements are actuated* in gangs so as to constitute a single work holding couple or pair (at least one jaw of such couple thus including several spaced and relative positionable portions as in subclasses 164, 265+ and 266) will not be placed in this subclass (37). Such jaws do not constitute "separate holding means" as defined above and placement will be in the appropriate subclass lower in the schedule.

(4) Note. A patent claiming the use of plural clamping means structurally capable of meeting the above criteria but disclosed as holding work with respect to a reference table, wall or floor, rather than with respect to another workpiece, is not placed here and will be found in subclasses 95+ below.

(5) Note. A device with two or more separate work holders which device includes mechanism for moving one holder, and the work held, relative to another holder, and the work held thereby, is not considered to be a work holder for this class (269); such device is an assembly mechanism for Class 29, Metal Working subclasses 700+. Articulation between holders and/or means whereby an operator may shift said holders, without mechanical advantage or lost motion, does not constitute "mechanism" for assembly. However, the provision of a work contacting guide to align or orient two or more workpieces, while an operator shifts the holders of said pieces, is considered to be sufficient "mechanism" for assembly.

(6) Note. Included, in this and indented subclasses, are patents to a device wherein the individual or separate holders consist of static structure insofar as the work contacting portion of the holder is concerned, e.g., a socket or groove into which a workpiece is inserted. However, plural grooves or sockets in a single bar or plate do not constitute "plural holders".
