TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN N. ARVIN, of Valparaiso, in the county of Porter, and State of Indiana', have invented a new and useful Wrench and Tongs; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, and letters of reference marked thereon, making a part 'of this specification, in which- Figure 1 is an elevation of my wrench and tongs -with the jaws open.

Figure 2 is a longitudinal elevation ofthe wrench and tongs with the jaws closed.4

The nature of' my invention consists in the use of a lever attached to the bar of the adjustable jaw by means of a, pin passing through the end of the lever and a slot made through the upper end of the bar, by which means the bar passing through the stationary lever will not be cramped or bound when the jaws are closed; and in providing two'straps attached to the stationary lever, and projecting upward i'ar enough to support the movable lever, which is adjusted between said straps, and held in position by means of a pin, upon which the adjustable lever operates; and further, in the use of a spring made fast to the movable lever, and operating against the stationary lever for the purpose of keeping the jaws ot the wrench open when notin use. By this arrangement the jaws ofthe wrench are held in suelha position that they can vbe conveniently used as tongs 0r pincers, and all kinds et' work where the several devices nam'edhavo necessarily been employed heretofore.

To enable others skilled in the `art to make and use m-y inventioml will proceed to describe its construction and operation. o

A represents the stationary lever, terminating at one end in the jaw o, through which is inade a inortiso for the shank, m, attached to the jaw P to pass through, as seen by the dotted lines Z. C shows straps rigidly attached to the lever-1A; for the purpose et' supporting the movable lever B held between the :straps C by means ofthe pin S, which is used as a fulerum. Bis the movable lever, having an open lnortise through which the upper end of the shank m passes, and is held in position by means of the pin n. D is the spring secured to the lever B, and extending down to lever A, and keeps the' jaws `O P open, as seen at g. l, when the wrench is not in use. Drawing X represents the top of the shank m, in which is made the slot U, through which the pin n is put. This slot is important in allowing the shank m to pass through the jaw 0 at right angles, notwithstanding the circular motion given to the pin n by the motion ofthe lever Bf a shows a common screw-driver made on the end ot' the lever B, and a shows a top view of the same. R represents the common claw for drawing tacks and other purposes. B shows a top view of the sume.

. Operation. l

Fig. l represents the invention with-the jaws O P open for grasping a nut or other article, as seen by the lines V. The levers A B must be grasped withthe hand, .which will shut'the jaws sufficiently close to .either turn :i nut, or for other purposes.

Having thus fully described my device, .what I claim, anddesire to secure by Letters Patent ofthe United States, isy The arrangementand lcombination ot` the levers A B, straps C, spring D, jaws O P, and shank m, when constructed substantially as and f'or the p'hrposes speciiied.

JOHN N.v ARVIN.
