@glatten tetes gamut @frn THOMAS E. HUMPHEEYS, 0E TEENTON, NEW JERSEY.
Letters .Patent No. 74,093, dated February 4, 1868.
IMPROVEMENT IN vIsEs;
TO ALL WHOM IT MAY CONCERN: i
Be it known thatI, THOMAS H. HUMPiIREYs, oiA Trenton, in the county of Mercer, and State of New Jersey, have invented new and useful Improvements in Cast-Iron Vises; and I do hereby declare that the foli lowing is a full and exact description thereof, reference being had to the accompanying drawings, which form part of the same, and to the letters of reference marked thereon, in whchi Figure 1 represents a side view of the vise.
Figure 2 represents the inverted sword or bar, with protected screw, and anadjustable thimble, D.
Figure 3 represents the shape of the sword or bar'as it passes through lthe scabbard B.
Figure 4 represents the mode of fastening and holding the nut E in its proper position in the scabbard B.
Similar letters of reference, where they occur in separat-e figures, denote like parts in all the drawings.
Myv invention consists of-an inverted keystone-shaped sword o'r bar, with a protected screw operating lwithin the sword or bar, with an. adjustable thimble on the screw, and the mode of securing the nut within the scabbard. v
In order to enable others skilled in the art to make use of my invention, I will proceed to describe the same with reference to the drawings. i
A represents the sword or` movable bar, B the stationary scabbard, and C the screw operating within the i nut Ekand shielded by the sword or bar A. The sword or bar A is made in an inverted keystone-shape for the purpose of making the bearings equal on' all sides, thereby preventing any more wear on one side than on the other, and also' preventing the sliding sword or bar A from having any swaying motion, because in openingolr closing the vise the jaws move on a horizontal line. The adjustable thmble D on the screw C has an inside thread, about half an inch in length, at the end c, being the opposite end from the journal a, so that when the screw C, which, by constant wear, becomes loose in thejournal a,it can be readily tightened by simply loosening the set-screw b, and holding the thimble D, then by turning the screw C until all the lost motion is taken up, and again tightening the set-screw b. The thimblc is held stationary, and all lost motion is taken up. This thimble can be made of either brass or iron.
Vises not possessing this advantage soon become loose in thc journal where there is. constant wear,` and" thus create great annoyance.
In iig. 4, the stationary jaw or scabbard B, an inverted T-slot is made, into which the bottom part of the i nut E is closely fitted or made to slide into, having a shoulder above the slot d, and the nut E is held firmly to its position by means of a set-screw, e, from the under side of the stationary jaw or scabbard B, making the nut perfectly-tight and secure. i
Having thus -fully described my invention, what I claim, and desire to secure by Letters Patent, is-
1. I claim the combinationof the dove-tail formed' slide or sword A, nut E, and adjustable thimble D, as arranged, shown, and' described.
2. I claim, in combination with screw C, the adjustable thimble D, operating as herein described.
