COMBINED ANV IL AND VISE.

SPECIFICATION forming part of Letters Patent No. 42 5,602, dated April 15, 1890. Applicatidn filed October so, 1889. as No. 328,618- (No model.)

T0 aZZ whom it may concern: 7 g

Be it known that I, CLARK FISHER, a Gilli. zen of the United States, residing in the city of Trenton, county of Mercer, and State of. have invented certain new and. useful Improvements in Combined Anvils:

New Jersey,

and Vises, of which the following is aspecification.

My'invention relates to such anvils as are,

1n various modes of application, provided with a movable vise jaw adapted by suitable connections, to be moved into and out of contact with the body of the anvil, which forms the permanent jaw.

The object of my invention is the construction of a device of the foregoing character which shall be both simple in construction and direct in action, and the parts of which shall possess the advantage that they may be easily put together and taken apart.

In the accompanying drawings I illustrate and herein I describe a good form of a convenient embodiment of my invention, the particular subject matter claimed as novel being hereinafter definitely specified.

In the drawings, Figure 1 is a side elevation, and Fig.2 a top plan view of an anvil embodying my invention. Fig. 3 is a transverse sectional elevation on the line to w of Fig. 1. Fig. 4 is a perspective View of the upper portion of the treadle lever.

Similar letters of reference indicate corresponding parts.

In the drawings, A is an anvil of any usual type. At one side of the anvil, and preferably, but not necessarily, at a point within the usual recess in the side of its base, is located a boss B, embodying a socket O, which is preferably integral with the base. The socketis preferably cylindrical and opens only through the top of the boss. In the side of the body of the anvil opposite the boss, are

two notches or indentations a, for a purpose explained hereinafter.

D is a movable vise jaw formed as a separate member but adapted to have its lower end entered within the socket O, and of such length that when so entered its upper end will be flush with the upper surface of the anvil. The lower end of said jaw which is entered within the socket, is preferably formed with a cylindric knob or enlargement d con= formed to said socket. The upper end of the movable jaw forms a vise face adapted to make contact with the anvil, the opposing side face of which is correspondingly flat. A draw bar E is adapted to be attached to said movable jaw and to pass through'an aperture extending, conveniently, in the disposition .of

parts shown, through the body of the anvil,

.and, vby-means of this bar, the movable jaw is operated. By carrying the bar through the anvil it is brought out on the side of the same on which the workman usually stands, and also allows of the lever by which said rod 6 5 is moved being fulcrumed upon the body of the anvil itself. The attachment of the bar to the movable jaw is conveniently effected by entering said bar through an aperture d in the jaw, and equipping its screw threaded 7o protruding end with a nut e. The aperture in the anvil through which the draw bar, as stated, passes, is designated a", and the bar is preferably provided at its extremity beyond the anvil with a head or stop E which limits its inward movement.

F is a lever, cast or forged preferably in substantially the form shown, and designed to operate the draw bar. Intermediately of its length, and at a proper distance below its upper end, the lever conveniently embodies or is provided with a projection or bend f, and to the crest of said bend is applied what I term a fulcrum bearing f'. The upper end of the lever is connected to the outer end of the draw bar in such manner as to be free for the slight play necessary in the change of positions which said parts undergo. I find it convenient to effect the connection by forming in the head F. of said bar E, a vertical 0 slot, e", in which the upper end of the lever F is entered and loosely fits.

A spring, G, is preferably interposed between the movable jaw and the body of the anvil which constitute the two jaws of the 5 vise, so as to maintain said jaws normally open. In the drawings I show this spring as being of the spiral variety, encircling the draw bar, and bearing either directly or through the medium of washers against the jaw and anvil respectively. It will now be understood that power or weight applied to the lever F below its fulcrum, will draw the movable jaw against the jaw face of the anvi], and that, upon the release of said lever, the spring will force it away therefrom. The lower end of the lever F may be shaped to conveniently receive whatever kind of 5 power or weight is contemplated to be applied to it, but I prefer to extend it outward and downward and to provide its lower end with a treadle t, so that the workman may close the vise by bearing upon the treadle with his foot. :0 As a result of the foregoing construction of the lever, it is, without additional supporting contrivance, maintained in place by the weight of its lower portion, it bearingthrough the feet f against the notches.

Having thus, described my-invention, I

claim and desire to secure by Letters Patent: i l

1. In combination, an anvil embodying an aperture and provided with a socket, a removable vise jaw separate from said anvil and likewise embodying an ,aperture and hinged at its lower end in said socket, a draw bar passed through both apertures and at its ends detachably connected respectively with the movable jaw and with the lever,a spring outer end, retaining devices at each end of said draw bar, a spiral spring encircling said bar between the anvil and the jaw, and a lever entered withinthe slot of the barand embodying fulcrum projections, substantially as setforth. I l

i In testiinony that I claim the foregoing as my invention I hereuntosign my name this 25th day of October, A. D. 1889.

p r CLARK FISHER.

In presence of- WM. 0. STRAWBRIDGE, J. BONSALL TAYLOR.
