JOHN H. FERGUSON,

WRENCH.
Specification of Letters Patent.
Patented Nov. 15, 1910.
Application filed February 26, 1910. Serial No. 546,059.
To all whom it may concern:
Be it known that I, JOHN H. FERGUSON, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Wrench, of which the following is a specification.
It is the object of the present invention to provide an improved wrench, and the invention aims primarily to provide an improved construction of combined nut and pipe wrench.
A further object of the invention is to provide a compact and simple construction of wrench of this type and to so house the adjusting nut for the wrench that it will not be liable to be injured.
I11 the accompanying drawings,Figure 1 is a side elevation of the preferred embodiment of the invention. Fig. 2 is a front edge view thereof. Fig. 3 is a view similar to Fig. 1 showing a slight modification. Fig. 4 is a sectional view showing a modified form of jaw, and Flg. 5 is a similar view showing a further modification.
In the drawings, the wrench is illustrated as embodying a stock 6 which is comparatively broad throughout substantially one half its length and at the outer extremity of its said broad portion is formed with a nutengaging jaw 7. The remaining portion of the length of the stock is slightly ofi'-set with respect to the broad portion 6, as indicated by the numeral 8, and terminates in a pipe-engaging jaw 9. It will be observed from the drawings that the jaw 7 projects beyond the lower edge of the stock, but that while the jaw 9 projects downwardly beyond the lower edge of the portion 8 of the stock, its extremity does not lie beyond the line of the lower edge of the portion 6 of the stock. It will be observed that the jaw 9 is serrated in its jaw-engaging face, as indicated by the numeral 10.
The portion 6 of the stock of the wrench is formed with a longitudinally extending rectangular bore 11 and the top wall of this bore is in a plane with the under edge of the off-set portion 8 of the said stock, and fitted for sliding adjustment in the said bore is a shank, indicated by the numeral 12, and at one extremity this shank carries a nut-engaging jaw 18 which is designed to cooperate with the jaw 7 in the manner illustrated in Fig. 1 of the drawings. The
opposite end of the shank is bifurcated, as at 14, and between the furcations is received and. secured, by means of a pin 15, the tang 15 of a pipe-engaging jaw 16 which jaw is designed to cooperate with the jaw 9, as shown in the said Fig. 1.
The upper edge of the shank 12 is of rack formation, as indicated by the numeral 17. The stock has its portion 6 recessedin its upper side, as indicated by the numeral 18, and fitted in this recess is the usual threaded nut 19 which is in mesh with the rack 17 and is rotated to adjust the said rack. The nut 19 is mounted to rotate upon a pin 20 inserted theret-hrough and seated at its ends in openings formed in the said stock through opposed walls of the said recess. This pin is preferably held in place by forming the stock at the outer end of one of the openings with a surplus amount of material, shown in dotted lines in Fig. 1 of the drawings, and indicated by the numeral 21, which surplus material is struck down after the insertion of the pin. As stated, a pin 15 is the means employed for securing the jaw 16 in place upon the shank 12 and it will be observed that the jaw is cut at an angle so that its lower edge will project below the plane of the lower edge of the shank 12. As a consequence the shank 12 will be prevented from being accidentally removed from the bore of the stock.
In the form of the invention shown in Fig. 3 of the drawings, the stock of the wrench is recessed in its under side and both edges of the shank 12 are of rack formation, as at 22. In this form of the invention, an internally threaded adjusting nut 23 is fitted upon the shank.
Whereas the jaw 16 of the wrench is rigid in the two forms previously described, in the form of the invention shown in Fig. 4 of the drawings, it is pivoted and a bowed spring 24 is fitted between it and the bottom of the bifurcation in the said shank 12. This spring may be so positioned as to either tend to hold the jaw open or closed, although it is here illustrated as holding the same closed. Where it is not desired to employ a bowed spring, as illustrated in Fig. 4, a helical spring 25 may be employed, as illustrated in Fig. 5 of the drawings.
What is claimed 1s A wrench comprising a stock comparatively broad throughout a portion of its length and formed at the outer end of its broad portion with a jaw, the stock having the remaining portion of its length off-set; with respect to the broad portion, the said broad portion bein r formed with a slot and the off-set portion ideing formed at its outer end with a jaw, the inner edge of the ofl'set portion being in alinement with the adjacent edge of the slot in the broad portion of the stock, the said stock being recessed at the point of juncture of its broad and off-set portions, a shank slidablyfitted through the slot in the broadened portion of the stock and having that edge which is presented toward the edge of the ofli set portion of the stock of rack formation, a jaw carried at one end of the said shank and cooperating with the first mentioned jaw a jaw carried at the other end of the shank and cooperating with the last mentioned jaw of the stock, and an adjusting nut mounted for rotation in the recess and cooperating with the rack edge of the shank, the last mentioned jaw upon the shank being oit-set in a direction away .t'ron'i the said inner edge of the oiT-set portion of the stock whereby to prevent \vitl'ldrawai of the shank from the slot in the hroadei'ied portion of the stock.
In testin'ioi'iy that I claim the foregoing as my own, I have hereto aflixe'd my signa ture in the presence of two witnesses.
