UNITED STATES PATENT OFFICE.
JOHN AENIS, OF CLEVELAND, OHIO.
FOLDING GRINDSTONE-FRAME.
SPECIPICATIQN forming part of Letters Patent No. 314,986, dated April 7, 1885.
Application filed August 6, 1884. (No model.)
To all whom it may concern:
Be it known that 1, JOHN AENIS, of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Folding Grindstone-Frames, of which the following is a specification.
This invention relates to frames for supporting grindstones, and has for its object to provide a folding frame which may be compactly folded together for storage or shipment, and having no loose parts to get lost or misplaced.
It consists of two shaft-bearings constructed in the form of hinged joints, containing friction rolls or rollers, said hinged joints having arms to which are secured the supporting-legs. Each pair of legs are also joined together by folding braces.
In the accompanying drawings, Figure 1 is a perspective view of my folding frame opened and spread, ready to receive the grindstone. Fig. 2 shows the same folded for shipment. Fig. 3 is an enlarged side view of the hingejointed bearing. Fig. 4is an edge view of the same. Fig. 5 is a vertical section of said jointed bearing, showing arrangement of frictionwheel. Fig. 6 shows the same joint having two friction-wheels.
AA are the two arms of a hinge, each having disks a a at the sides, arranged to fit together, and leaving space between the two inner ones for a wheel, B. Said disks are joined together by a bolt, 0, upon which they, as well as the Wheel,turn. The lower ends of said arms A are made hollow to form sockets for the rethe legs, while their upper ends are notched,
so that they may be detached from the buttons to allow them and the legs to be folded to get-her.
Having described my invention, I claim- 1. The combination, with the socketed arms A A, having prongs e e, and provided with disks a a, and united by bolt 0, of the intermediate friction wheel or wheels, B, substan tially as described, and for the purpose specified.
2. The folding grindstone-frame consisting of the hinged joint composed of the socketed arms A A, having prongs e c, and provided with the disks a a, united by bolt 0, and the intermediate friction wheel or wheels, B, and the legs D D, provided with the pivoted braces E E, all substantially as described.
