IMPROVEMENT IN WRENCHES.
The Schedule referred to in these Lettera Patent and making part ot the same To all persons to whom these presents shall come:
Be it known that -I, SYLvANUs CHAPMAN, of Charlestown, in the county of Middlesex and State of Massachusetts, have invented a certain Anew and useful Improvement in Wrenches, and that the following is a full and exact description of the same, reff erence being had to the accompanying drawing.
The presentinvention relates to monkey-wrenches, so known, and consists in the movable jaw, which, with its shank, is composed in itself of two loops or clasps to embrace the stock or bar of the wrench, is in and of one, piece of'metai, the operating nut being arranged between the said loops, heilig so constructed by and at one `ot' the said loops that the grip ofthe wrench-jaws, when the wrench is turned in the one direction, will be ,firm and rigid on the device to which the jaws have been previously adjusted, but, when the wrench is turned in the opposite direction, said grip of the jaws will bc self-relieved, the jaws sliding freely around on the said device.
The' wrench is thus made susceptible of use for purposes where a ratchet-wrench heretofore is ordinarily employed.
1n the accompanying drawing my improvement in wrenches 'is illustrated.
Figure 1 is a side view of a monkey-wrench construct-'ed according thereto, the movable jaw and operating nut being in partial section.
Ain the drawing represents the stock or bar 'of a monkey-wrench.
This stock A at one end terminates in 'a fixed jaw, di, and`at the other end has secured' to it, by means ot' a screw-nut, U, a handle, D.
The stock A, in transverse section, is made of a square shape, with'thc corners or edges thereof rounded oi, and constructed with screw-tln'eads, a, along between the tixed jaw B and handle D.
E, the movable jaw of the wrench.
11; the shank to jaw.
This shank is constructed with two loops or clasps,
G and VH, the one in the tail of the jaw, and the other removed therefromfbut connected on one side by the bar F, leaving a space, J, between the two clasps.
VThe clasps Gr4 and 1I, jaw E, and 'connectipgbari, are of one and thesame piece of metal, and. by the clasps the jaw is arranged upon the stock A, with the face K of the jaw E toward the face L of vthe fixed jaw The internal periphery of the clasp G is in one di- Areetion made larger than the diameter of the stock 'Arin a similar direction, (see drawing,) to allow the jaw to have a vertical play or movement on the stock, the center or fulcrum of motion being at the other clasp H, that` by its internal periphery, is made of ci' about the periphery of `the stock.
L2, a socket in tail of jaw in.
In this socket is located 4a spiral spring, M, bearing on the stock A to hold the clasp G et' the jaw by its underside against the underside of the stock.
Within the socket L2 of the movable jaw is placed a pin, p, formed with a head at one end,'in such a manner that the pin is embraced or operated by a suitable" spring, so as to force the head of the pin against the stock portion of the wrench.
N, the operating nut of the wrench. This n'ut is provided with a screw-thread of suitable shape to gear int-o the thread of the stock A, on which, when the wrench is put together, it is placed in and between the two loops and clasps of the .movable jaw.
By turning the nut N to the right o r left, the mov able jaw will be, moved, ,as the case may be, toward or away from the iixed jaw, as in ordinary monkeywrenches.
\Vith a wrencn constructed in the chisp- G of its movable jaw, as described,applied and adjusted to a tube, pipe, or other cylindrical surface, when the wrench is turned in the one direct-ion, that is, in a similar direction to that in which the jaws project beyond the stock A, the grip of the wrench-jaws on the tube is rm and rigid, but such grip, when the wrench is turned in the reverse direction,` is released, the jaws passing freely over the pipe, &c.\vithout any act-ion,on`it.
The spring M arranged within the jaw-clasp facilirates and increases the releasing movement-of the jaw, as aforesaid.
From the above .description it is obvious thata monkey-wrench is constructed so as to be suscepti ble of use as ratchet-wrench.
Having thus described my invention,
What I claim as my invention, and desire to secure by Letters laten'ais l. The pin p', arranged-within the socket If of the movable jaw, in such a manner as to be operated upon by `a spring, M, substantiail y as described, for the purpose set forth.
2. The connecting bar F, formed with the loops G and H, in one piece, with the spring 'M Aarranged within the socket L2 of the jaw E, substantially as.
described. y
The clasps G and H, jaw E, and connectingbar F, formed iu one piece, withthe operating nut interposed 4between the clasps G' and H, and the The above specification of my invention signed by mc this 22d day of June, A. D. 1870.
sYLvANUs CHAPMAN.
