CLASSIFICATION-185-MOTORS : SPRING, WEIGHT, OR ANIMAL POWERED
Class Definition for Class 185 - MOTORS: SPRING, WEIGHT, OR ANIMAL POWERED
CLASS 185,MOTORS: SPRING, WEIGHT, OR ANIMAL POWERED
SECTION I - CLASS DEFINITION
This is the class of spring, weight, and animal powered motors and is specific to motors of these types and to plural arrangements of such motors.
(1) Note. Composite motors are defined as involving a plurality of energy converting means, each of which is capable of delivering an output to a load which is not one of the means. Accordingly, the combination of two motors in which the sole function of one of the motors is to wind the second motor or to otherwise condition it for performing work for delivering energy is not classified as a composite motor but merely as a single motor having winding means.Plural motors, both of which are Class 185 motors, are classified in this class. For plural motors of diverse types, one of which is a Class 185 type motor, see Lines With Other Classes, below.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Plural motors of diverse types, one of which is a Class 185 type motor, are classified in appropriate subclasses of Class 60, with the exception noted in the paragraph below. Relative to combinations involving a Class 185 motor and a winding arrangement therefor, Class 185 takes such combinations when both the output motor and the winding motor are Class 185 type motors. Where the winding motor is not a Class 185 motor (as, for example, tide motors), classification is in the appropriate subclass of Class 60 with one exception. Combinations involving an electric motor for winding a Class 185 motor, the electric motor being incapable of performing other work, are classified in the appropriate winding subclasses of this class.

This subclass is indented under subclass 730.1. Subject matter wherein means are provided to sense a condition or change of condition in the drive train and in response to such sensing effect a control function on the drive train. (1) Note. Usually the control function is a change in the speed ratio.

810.2 Input and output exchange functions:
This subclass is indented under subclass 810.1. Subject matter wherein in response to the interchange of roles between the transmission input member and the transmission output member the path through which power is transmitted is changed. (1) Note. To be placed herein the transmission must have a useful load at each of its input and output ends. Most of the patents herein disclose either motor-generators or motor-pumps used to start an engine which in turn drives the generator or pump.

814 With safety device or drive disconnect:
This subclass is indented under subclass 813. Devices including mechanism which prevents the assembly from improper functioning and/or responds to some imperfection, deficiency or fault in the functioning of the assembly to prevent further functioning.
815 With locating point adjusting:
This subclass is indented under subclass 813. Devices having one member on one part and another member on the other part which, by contact together, constitute a means for determining the angular position of the shaft, and in which at least one member is provided with means to change its position on the part and/or its point of contact with the other member.
816 Preselected indexed position:
This subclass is indented under subclass 813. Devices having means to interrupt and stop rotation of the shaft at a physically predestined position. (1) Note. The interruption of rotation responsive to a determination on the part of a human operator is not considered to be physically predestined.
817 Sequential:
This subclass is indented under subclass 816. Devices having a single initiator or source of power for rotating the shaft or load and having means to halt the shaft or load at each of a series of successive, predetermined positions.
818 Skip position:
This subclass is indented under subclass 817. Devices having means to cause the load or shaft to pass one or more preselected positions without stopping thereat.
819 Held by torque:
This subclass is indented under subclass 817. Devices having means to generate a rotating force to provide the angular repositioning of the shaft or load and using all or part of that force to hold the body against a position stop. (1) Note. This is usually accomplished by means of allowing the motor to stall without deenergization.

822 Interlocked rotator and brake:
This subclass is indented under subclass 817. Devices wherein a common initiator or common source of power both turns the shaft or load and either permits rotation or prevents further rotation - the operation of turning is a condition precedent or subsequent to the operation of permitting or preventing rotation.
823 Diverse-type brakes:
This subclass is indented under subclass 822. Devices wherein the means permitting or preventing rotation comprises at least two distinct types of holding means, e.g., friction brake and positive brake.
824 With axially acting friction brake:
This subclass is indented under subclass 823. Devices wherein the operation of one of the holding means is effected by relative movement between radial face brake surfaces along the axis of the shaft or load.

The SUBCLASSES of those two classes will be reviewed in detail and noted and the subclass definitions will assist us in compiling a really good set of claims to be written into the United States Patent Application. We will draft a most basic set of claims and include them with the Provisional Draft. The rules state that you are not required to furnish a set of claims with the provisional draft, this does not prevent you from sending them in also with the provisional , if you have any. If a United States patent is issued to you for your invention you can claim the original filing date that the provisional was recorded in the USPTO as received properly from the USPO Express mailing tracking number.
