CHAS. F. PIKE

Be it known that I, CHARLES F. PIKE, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Prosthetic Arms for Diving-Bells.

My invention has for its object to provide a diving bell or car, having exteriorly affixed thereto an improved prosthetic or mechanical arm or device constructed to rotate on its axis, while its individual component parts are free to move independently in many directions by the application of mechanism which is under the control of and operated by the diver within the bell or car.

My invention consists, primarily, in the provision of a prosthetic arm for a diving-bell provided with a pair of jaws which are opened and closed by means of atmospheric or hydraulic pressure controlled by the operator within the bell; second, in the provision of said jaws secured to a cylinder which is pivotally attached to a pivoted supporting-frame, upon the latter of which is secured and supported mechanism for oscillating said jaws and cylinder on the pivotal bearings of said cylinder and for rotating the same independently of said supporting-frame; third, in the provision of said jaws and cylinder with the supporting-frame, the latter being pivoted upon arms projecting from the main shaft or drum of the apparatus, and having a gear-connection therewith, and also with a gear-wheel placed upon a shaft which extends into the bell, by means of which said supporting-frame, cylinder, and jaws are together simultaneously oscillated on the pivotal bearings of the said supporting-frame; fourth, in the provision of the main shaft or drum of the device, formed with a spur-wheel which meshes with a rack secured to a piston-rod which is operated by hydraulic or atmospheric pressure to rotate said drum and carry with it the supporting frame, cylinder, and jaws, all of said parts being simultaneously rotated together; fifth, in the general combination, arrangement, and construction of parts, as hereinafter more particularly set forth.
