UNITED STATES PATENT 1 ANTON MEYER, OF ST. LOUIS, MISSOURI.

WRENCH.

sPEorFIcA'rIorr forming part or Letters BatentNo. 648, 769, dated May 1,- 1900. Application filed November 24, 1899. Serial No. 738,124. (No model.)

To all whom, it may concern:

Be itknown that I, ANTON MEYER, a citizen of the United States, residingat the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Wrenches, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification;

My invention relates to that class of wrenches supplied with a sliding jaw movable on the shank of the wrench, and has for its object the construction of a wrench of this character which may be readily adjusted in any desired position and also readily disas sembled for the purpose of renewing parts of My invention consists in features of novelty hereinafter fully described, and-pointed out in the claims.

Figure I is a perspective view of my im-' proved wrench. Fig. II is a side view of the head part of the wrench, showing the sliding jaw member. partly broken away and partly in section. Fig. IIIis an enlargeddetail perspective view of the spri n g-carryin g end of the Fig. IV is adetail persliding jaw member. spective view of the re'movablecatch carried by the sliding jaw member. Fig. .V shows a modification ofthe sliding jaw member.

1 designates the shank or handle of the wrench provided at one of its edges with ratchet-teeth 2 and having a fixed jaw 3,. provided with a heel 4.

. 5 designates, the sliding jaw member, this member being bifurcated throughoutits main portion to fit the shank 1 and embrace the heel 4 of the jaw 3. The jaw member 5 is provided with *a jaw 6, that opposes the jaw 3. Fixed to the inner end of the jaw member 5 is a spring '7, that bears against the edge of the shank 1, opposite the ratchet-teeth. 2. The jaw member 5 'is formed with arms 8, that project beyond the ratchet-teeth2, and are provided with apertures 9, (see Fig. 1H,) triangular in shape, that receive a catch 10. The catch 10 is triangular in cross-section and is formed with sharp edges, of which the one facing the-ratchet-teeth is designed to engage said teeth for the purpose of holding the jaw member 5 fixed in any, position to which it may be moved. The catch 10 is insertedin the apertures 9. and is removably secured therein to the arms 8 by screws 11, hearing washers 12. A

In the practical use of the wrench the jaw member 5'maybeinoved outwardlypn the depression of the spring 7, which causes the catch 10 to be moved out of engagement with the ratchet-teeth2, and when the pressure-is relieved from the spring the catch isreturned inwardly under the action of the springto engage one of the teeth '2 at the desired position. When the jaw member is to be moved inwardly, it is only necessary to exert pressure against the jaw 6, which will cause'the catch'lO to ride over the teeth 2. By utilizing a catch of triangular shape in cross-section I am enabled to providea number of,

edges, either one of which may be presented to the ratchet-teeth on tlie withd rawal andi'e insertion of the catch to bring the desired edge thereof innermost. shape described, it is also possible to sharpen its edges when they become dulled, which maybe readily accomplishedwith the catch removed. The removal of the catch also permits the removal of the jaw member, so that in the event of a breakage of said meniberit may be repaired or replaced by a similar part.

In Fig. V, I have shown a modification of the sliding jaw member. in which the jaw G is of curved shape to render it applicable for dle 0r shank provided with ratchet-teeth and a jaw, a jaw member provided with a jaw,

and arms projecting from its inner end, --a removable catch of triangular shape in crosssection seated in said arms adapted to engage said ratchet-teeth, and a spring carried by The catch being of the said jaw'member adapted to bear against the edge of said shank opposite said ratchet teeth, substantially as described.

3. In a wrench, the combination of a shank to bear against said shank to hold said catch or handle provided with ratchet-teeth and in engagement with the ratchet-teeth, sub- 10 having'a jaw, a heel projecting rearwardly stantially as described. from said jaw,a sliding jaw member bifur- 1 7' cated to fit said shank and said heel, a re- ANTON MEX E movablecatch carried .by said jaw member In presence of adapted to engage said ratchet-teeth, and a' E.
