Description

@nitro gratta @anni @Hina ORLANDO V. FLORA, OF MADISON, ASSIGNOR TO HIMSELF, GEORGE SHAN- NON, AND D. C. ROBINSON, OF JEFFERSON COUNTY, INDIANA.
Letters PatentNo. 79,565. dated July 7, 1868.
IMPROVEMENT IN UARPENTBRS VISBS.
dbi Krlifmte feierten In in their @rims atent aut making part nf the time.
4TO ALL WHOM IT MAY CONCERN:
Be it known that I, ORLANDQ V. FLonA, of Madison, in the county of Jefferson, and State of Indiana. have invented new and useful Improvements in Parallel Vises; and I do hereby declare that the following is a. full,
clear, and exact description thereof, which )vill enable those skilled in the art to malte and use the same, refer-l ence being hadto the accompanying drawings, forming part of this specification.
This invention relates to that class of vises which are adjusted for clampinglarge or small work by means of ratchcts, while a screw is used in conjunction with the ratchet, for the purpose of holding the work rmly iu the jaws, a half' turn` of the screw being sufficient for that purpose.
Figure 1 is a. perspective View of the rise, with a part sectioned.
Figure 2 is a. side elevation of the working part.
Similar letters of reference indicate corresponding part-s.
A is the table or bench, and B the loose jaw of the vise.
C is a sliding beam, with a few inches of screw-thread cut on its rear end, which turns in the nut E, simply for tightening thejaws against 4the article to bc clamped, shown at M.
The saddle-piece G is attached rigidly to the nut E, and slides on the stationary bar D, on the under side of which is the ratchety C.
Through the lower part of the saddle-piece G is passed a bolt, on which is pivoted the diagonal brace H, said brace being attached at or near the lower end of the movable jaw B, and passes backward and upward through a vertical slot in thestationary jaw of the vise. This keeps the movable jaw always in a position parallel, or nearly so, with the stationary inw. i
On the rear end of the brace H is the ratchctLplated, which is permitted to engage and discngage with the ratchet C because of the opening in the rear end of the brace H being enlarged vertically. These ratchets engage when any article (M, iig. 1) is placed'in the jaws, and the screw tightened, bythe action of the movable jaw B pressing the diagonal brace H upward, and thus locking the nut E and saddle-piece G firmly to the stationary har D.
To unclamp, the screw is first reycrsed till the article, M, is loosened, and then the beam C is free to move or slide in or out, at the pleasure of the operator, taking care to slide the'jaw B up to the article to be clamped before turning the screw.
The ratchets are shown engaged'in Eg. 1, and disengaged in g. 2.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination oi' thei saddiepiece G'with the short ratcheton the end of the brace H, having the `vertically-slotted opening in the said ratchet-brace, thusrendering the disengagement of the ratchets c and d automatic, when the article clamped is released,l substantially-os speciied.
ORLANDO V. FLORA.
