UNITED STATES PATENT OFFICE.
OYRUS WV. ORENSHAW, OF ATHENS, ALABAMA, ASSIGNOR TO HIMSELF AND J M. TOWNSEND, OF SAME PLAGE.
IMPROVEMENT IN SCREW-PRESSES.
Specification forming part of Letters Patent No. 155.862, dated October 13, 1874; application filed July 25, 1R74.
To all whom it may concern:
Be it known that I, OYRUS W. ORENSHAW, of Athens, in the county of Limestone and State of Alabama, have invented a new and Improved Press, of which the following is a specification:
The invention will first be fully described, and then pointed out in the claim.
Figure l is a side elevation of my improved press. Fig. 2 is a plan view. Fig. 3 is a sectional elevation taken on the lines x w of Figs. 1 and 2. Fig. 4 is a sectional elevation of the nut, taken on the line y y of Fig. 5; and Fig. 5 is a horizontal section taken on the line z z of Fig. 4.
Similar letters of reference indicate corresponding parts.
A represents the screw, which has a semicircular groove, B, instead of the usual screwthread; and O represents the nut, which also has a semicircular groove, D, instead of the usual thread, and besides it has a circular spiral channel, E, connecting each end of the spiral groove through the nut, which has a hollow spiral flange, F, to provide for the passage. G represents the balls, with which the spiral groove and the return-channel are filled, so as to form a continuous row of balls on which the screw rolls, instead of sliding on threads, to lessen the friction.
When the screw turns downward the balls roll down into the channel E and return to the top of the nut, those being forced down by the screw pushing those in the channel E up to the top, and when the screw turns upward the balls roll up in the groove and pass down in the channel.-
I propose to make the bottom of the press of three timbers, a, a, and b, and to extend the as new and desire to secure by Letters Patl ent- The combination, with screw A B, of the spirally-grooved nut O,returncl1annel E, and continuous line of balls G, as and for the purpose described.
OYRUS W. ORENSHAW.
