IMPROVEMENT IN VISES.

v'lO ALL WHOBI I'1 MAY CONCERN:
Be it known that I, A. JAMESON, of Trenton, county of Mercer, State of NewJersey, have inventedv an improvement in Adjustable Vises;4 and I do hereby declare the following to be a full, clear, and exact description of the same.
My invention consists of a plate, a disk, and a bolt constructed and arranged for the confinement of avise to and its adjustment on a bench or table, substantially as described hereafter, so that the plan of piercing and wounding the bench heretofore practised in connection with adjustable vises may be avoided, and so that the adjustment may be rapidly eiected. I
In' order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Figure 1 is a side elevation of my improved adjustable vise.
Figure 2, the same partly in section.
Figure 3, a plan view; and
Figures 4 and 5, detached plan views of parts of the dcvicedrawn to an enlarged scale.
A A are the two jaws of a vise, a hollow projection, a, on. the jaw A iitting so as to slide freely in the tubular projection b at the rear of the jaw A. A screw, C, on the outer end of which is the usual handle, e, passes through the jaw A and its projection a, and into a stationary nut in the tubular projection b. At the under side of the jaw A, and forming part of the same, is a circular projection, d, and between the latter and a circular plate, G, which is secured by screws h to the top of a bench or table, X, is a circular disk, H, in the edge of which are recesses or notches, il, Through the plate G and disk H passes the square portion of a bolt, I, the upper end of the bolt being cylindrical, and having threads adapted to internal threads in an opening in the centre of the projection d, and the head n of thc bolt bearing against the underside of the plate G, which is recessed, as shown in fig. 2. The opening a in the centre of the plate G is of such a size that the bolt I can revolve freely independently'of the plate, while the square portion ofthe bolt lits snugly in the square opening y-in the disk H, so that on turning the latter, the bolt will also turn. On the upper side of the plate G is an annular projection, m, which fits into a recess in the under side of the plate H, as shown in iig. 2. When the vise has been adjusted to any desired position, the disk H is turned (by means of a rod inserted in' one of the recesses) in the direction of its arrow, tig. 1, until the under face of the projection d is brought to bear so firmly on the face of the disk-H, and the latter is bound so tightly to the plate G that the vise is secured in its position. On turning the vise in a direction contrary to'that pointed out by the arrow, iig. 1, the bolt 1 will be slightly loosened, so that its head no longer bears against the under side of the plate'G, the vise may therefore be again adjusted to any position, (the vbolt and disk H turning with the vise,) and may be secured after adjustment as before. still simplerA plan of adjusting the vise, especially if it be of small size, is by holding the disk II between the finger and thumb of one hand, grasping the vise in the other, and turningv it to a position near to that-to which it has to be adjusted, and then turning the vise a short distance in a direction contrary to that shown by the arrow in fig. 1, while the disk is prevented `from turning. lhe projection m serves to maintain the disk laterally in its position, and prevents any lateral pressure from being brought upon the bolt. It has heretofore been customary to secure an adjustable vise to a bench by a bolt passing directly through the latter, secured to the vise, and furnished with a tightening device beneaththc bench, which is thus more or less wounded, an evil obviatcd by my improvement, in which simply screws only are neccssaryfor securing the plate G to the bench.
The main advantage of my invention, however, is the facility with which the vise can be adjusted and secured after adjustment. Without confining myself to any specific form or construction of vise, I claim as my invention, and desire to secure by Letters Patent- The combination of' the plate Gr, disk H, and bolt I, the whole being constructed and arranged for the confinement and adjustment of a vise on a bench or table substantially as herein described.
In testimony whereof I have signed my name to this specification in the presence of twosubscribing witnesses.
ABIEZER JAMESON.
