RETARIDING MECHANISM.

Specification of Letters Patent.

Patented Sept. 19, 1911.

Application filed August 25, 1910. Serial No. 578,889.

To all whom t1 may concern:

Be it known that I, FRANK HEATH, a citizen of the United States, residing at National City, in the county of San Diego and State of California, have invented certain new and useful Improvements in Retarding Mechanisms, of which the following is a specification.

My invention relates to improvements in retarding mechanism in which the retardation is absolute and steady and the objects of the improvements are to provide a mechanism that is simple in construction, steady in its action and very positive and it can be used to prevent an electro-magnet from producing a too quick or rapid movement on the part magnetically affected, and it is more particularly adapted to be used in connection with railway signal systems. I attain.these objects by the mechanism illustrated in the accompanying drawings in which Figure 1 is a side elevational view of the complete mechanism, and Fig. 2 is a plan view thereof.

Similar characters of reference refer to similar parts throughout the several views.

I have shown the mechanism in connection with a magnet which actuates its operation. The flywheel 1, coil spring 2, cable 3, lever 4, pivot 5, adjustments 6, and adjustable pivots 7 and 8, represent the principal parts of my invention. The flywheel 1 is an ordinary balance wheel pivoted on pivot points 1 and provided with a coil spring 2, one end of which is attached to said wheel 1 and the other end attached to the adjustable pivot 8. On the other side of said wheel and on the axle thereof is wound a cable 3 which extends to an operating lever 4. This wheel 1 is for the purpose of retarding the quick action of lever 4 by its taking some time to take up the action and get into motion. The spring 2 is for the purpose of turning said wheel back into its original. position when the counteraction of the lever is released the cord winding around said axle, and propelling said wheel when the counteraction is in operation and winds on said axle when said action is released and spring 2 operates.

The adjustable pivot points 7 and 8 are simple supports each provided with adjustable thumb screws which are provided with simple recesses in their inner ends adapted to fit the pivot points 1.

The lever 4 is pivoted upon pivot support 5 which is a simple support provided with pivot point bearings. Between pivot point 5 and the point of the cord attachment and adjacent to pivot point 5 is the adjustment 6 which is a simple standard screwed down to the base 9 and provided with adjustment screws 6 one on each side of said lever which are adapted to regulate the action of said lever. On the outer end of said lever at point 4 any operating mechanism that it is desired to retard is attached. In this case I have shown a magnet 10 in connection.

It will be readily seen that any quick action on the end 4 of lever 4 will be retarded by flywheel 1 until it gets in motion when its momentum will cause it to revolve without further action thereon and that the spring 2 will carry it back to its original position when the lever 4 is released.

Having thus described my invention what I claim as new and desire to claim by Letters Patent is:

1. A retarding mechanism, comprising a flywheel, an actuating spring attached thereto, supports therefor, an axle on said wheel, a lever, a cable with one end around said axle, its other end being attached to said lever, the latter being pivoted and an adjusting means adjacent to said pivot, all substantially as set forth.

2. A retarding mechanism, comprising a flywheel, an axle thereon, means attached to one side of said wheel for actuating it in one direction, an actuating lever, a cable attached to and wound onto said axle and to said lever for actuating it in the opposite direction, adjustable supports for said wheel, adjustable supports for said actuating lever, and adjustable means for regulating the movement of said lever, all substantially as set forth.

3. In a retarding mechanism the combination of a magnet, an armature having an extension in connection therewith and pivoted adjacent thereto, adjustments for regulating the movements of said armature, a cable attached to the extending end of said armature, an axle around which the other end of said cable is wound, a fly wheel mounted on said axle, means for revolving said axle, so as to wind said cable thereon, and adjustable supports for said axle, all substantially as set forth.

4. A retarding mechanism, comprising a base, a primary actuating mechanism, a

lever pivotally mounted upon said base, means for regulating its amplitude of oscillation, a fly Wheel, pivot'bearings upon which said fly Wheel is rotatably mounted, a cable connecting said fly Wheel with said lever, and secondary actuating means for rotating said heel, all substantially as set forth.

In testimony whereof, I hereunto subscrlbe my name 1n the presence of tWo sub- 0 scrlblng wltnesses.

FRANK HEATH.
