T 0 all whom it may conc rn:

Be it known that I. it 1111,1111 Coon. :1 ettr zen of the United States, and a resident of 1 ltllll])lllll'g. in the county of 'arren and State of New Jer e v. have invented a new 9 and Improved Ratt-hetdl'reneh, of whieh the following is a fall. clear, and exaet de script 1011.

This invention t'GlItteF to ratehet wrenches. 5 and the object ot the invention is to prodnt'e a wrench having a ratchet wheel presenting a soeltet which may he applied to the head of a not or bolt for rotating the aarne. Thiaratchet wheel inionnted in a htlllltt llt ratrhet head 111 11 i.' adapted to be advanced lav n'te anf i-of a lever operating t'hrongh a pawl. The isoelli'et in tinratrthet wheel eon strnt'teil in 11el1 a way as to ena le it to retain i1 111052111111tit-61131111: it to be ttl-jed as 11 pipe wrench. i

The invention concern itself also with the n1ean= for retaining the parts inthe ratchet head.

The invention eonsists i11 the etnistrttetiotr and combination of parts to described hereinafter and forth in the claims.

Reference is to be had to the :1 :o111p:1t1 ing drawing. forming a part of this speeihe more fully partnsnlarlv set titration. in which similar eharaeter olfa'el erenee indieate corresponding parts in all the figures.

Figure l is: a plan of a wrench e'onstrneted accordingto my invention and showing; the same with the cover closed; Fig. 2 is. a view similar to Fig. 1. but r howing the wrench with the cover open So as to expose the parts within the ratehet h ad; Fig. 3 is a longitudinal seetion taken through the wrench on the line'33 of Fig. :2; Fig. 4- is a plan of the ratchet wheel and showing one of the removable inset. also :1 plan of the ratchet wheel and show ing a pe -ial pipe wrench. the jaw seating in the socket $11 as tn adapt the wrench l'or unset-owing pipes or t11d l ig. ti is a ide elevation of the plain inset jaw \\'ill('l1 is shown itt Fig. i: and Fig. T is a front elevation of the pip or stud jaw shown in Fig.

Referring more particularly to the parts, 5

1 represents the body of a wreneh which has-an elongated handle or lever 2 termict jaws' which t'edttee the size of 1 jaws in po: iti.n1; Fig". .1 is

This ratehet head 2 has a trenlat' trhanther I} whteh lttftlVt'S :1 ratehet lHtYUlLf peripheral teeth 3. and these wheel 1. teeth are adapted to engag with a pawl G which is mounted in the handle near its -point. of attachment. with the head. The pawl has an elongated tail T. and an enlarged substantially eirt-alar head 'a'. This f ciretdar head is received in a :fiiltlatlltiztlly 1 Circular poeltet i which has :1 substantially {*traight neck 11" which extends therefrom l 111d ez1t through the side wall of the ehatn- W1 3. as shown.
