' Application filed April 1, 1922. SerialNo. 548,698.

Be it known thatI, JAMES F. BAILEY, a citizen ofthey United States, residing at Columbia, in the "county of Richland :t and State of South Carolina, haveinvented certain' "new "and useful Improvements in Wrenches 1 andll do hereby declare the following'to be a full, clear, and exact description of the" invention," such as will enable others skilledin the artto which it appertains' to make and u'sethe same.

This inventionrelates to a tool of the wrench type embodying a handle and inner and: outer j aws, .the inner jaw being slidable along'the handle and held inthe required adjusted position primary object of the invention is the provision of a wrench of the .type aforesaid embodying an improved form of handle and j awstructure and arrangement, whereby the tool maybe cheaply manufactured and assembled and islcapableof being effectively used either a'nut or pipe wrench, and which may .have both jaws fixed but relatively 'adjustable, or which may have one of thelja'ws relatively fixed and the other pivoted, according' toj the specific formation of the tool. j

Other'o-b jects and'a'dvantages will be apparent and suggestthemselves as the nature of theinvention is understood.

While the drawings illustratean embodiment of the inventionitjis to'be understood.

that in adapting the same to meet different conditions and requirements, various changes in the form,proportio n and minor details of construction 'may be resorted to without departing from the nature of the. invention. "Referring to thelacco" panying. drawings forminga partof the application, Figure 1 is a side-view-of a wrench embodying the invention, j Figure 2 is a view sim'ilar'to Figure 1, the handle section .on the near side being removed, j v Figure 3 is a rear edge view of the wrench,

Figure 4i is a transverse section on the line 4t of Figure 1, looking in the direction of the arrows, V

Figure 5 is a detail view of the outer jaw section separated to show more clearly the tongue and groove joint between,

Figure 6 is a side view of a modification, Figure 7 is a rear edge view thereof, Figure ,8 is a detail view of the outer end portion of the handle with the near section removed and the outer jaw in section,

. Figure 9 is a detail viewof the inner jaw anda portion of the shank to which the jaw is ivoted, k

Figure 10 is a detail longitudinal section. on-the line '1010 of Figure 6,

Figure 11 is a detail section on the line l1'11"of Figure 6, and "Figure 12 is a detail view of the. facing or grip for the inner pivoted jaw.

Corresponding and like parts are referred toin" the fo-llowingdescription and designated in'the several 'views of the drawings by like reference characters. i The wrench comprises a handle and an outer and an inner jaw, the latter being slidable along the length of the handle. The handle is of sectionalformation, the sections being of similar or like formation and each section comprising a bar 1 and a semi-cylindrical portion 2,-the latter having an inner rib 3 at its outer end which constitutes an element of'the swivel connection between the handle and the adjusting nut by means of which the inner jaw is moved. When the sections ofthe handle are assembled, the bar portions 1 are spaced'apart andextend in parallel relation, whereas the semi-cylindrical portions 2 come together and are secured in any manner, either by fastening-s ior by being welded. The fastenings 4 may consist of rivets, bolts or machine screws. The outer jaw 5 is fixed and comprises similar sections which are formed with the respective sections of the handle. A tongue and groove joint is formed between the sections comprising the jaw 5 to insure the strain on the jaw when the tool is in operation being uniformly sus tained by both sections. The tongue is designated by the numeral 6 and the groove by, the numeral 7 and these elements match when the sections of the jaw are assembled. Fastenings ,8, such as rivets, machinescrews orbolts, connect the sections of the .j awwhen the parts are placed together. I

The inner jaw 9 isslidable lengthwise of the handle towards and away from the outer fixed jaw. The jaw 9 has a shank 10 which is slidable between the bars l and into the cylindrical portion 1 of the handle. A threaded stem 11, forming a part of the shank 10, cooperates with a nut 12 which is disposed within the cylindrical portion of the handle and has a swivel joint connection upon its outer side to enable the hand to obtain a firm grip thereon whenrotating the nut 12 to adjust the jaw 9. Theinner'or head portion of the jaw 9 receives the bar portions 1 of the handle, whereby the jaw .is'braced so as to withstand-the strain .to

which it is subjected when the tool is in operation. The jaws 5 and 9 are relatively fixed, thatis, they have no pivotal movement, the outer jaw 5 being immovable and the inner jaw 9 adjustable. v

In the modification shown in Figure 6 and the detail views thereof, the general construction and arrangement of theltool corresponds with that herein before described, corresponding parts being designated by like reference characters The main difference resides in the innerjaw and its mounting, the same being pivoted and both jaws being disposed at a right angle to the length of the handle,,wh-ereas the corresponding aws in the formshown in Figure 1 are inclined to the handle.

The inner pivoted jaw 15 of the modificationisformed with a tongue 16 which is pivoted tothe shank 10, the forward end of which is cut away to receive the tongue 16. A pivot 17 passes through the over- Y lapping parts and pivotally connects them.

A spring 18 is interposed between the forward portion of the jaw 15 and the handle 1 and serves to hold the gripping jaw 15 pressed outwardly to grip a pipe or like article and enable said jaw to ratchet when oscillating the wrench to turn the' pipe or other work gripped between the two jaWs.

. The r'ecesses'19 formed in they sides of the jaw 15 are forwardly widenedto admit of i I the jjaw'having a limited pivotal'movement when the tool is in operation. jaws has a facing or grip section 20 detach.

I ably fitted thereto and formed of high grade which is essential to admit of its ratcheting Each of the steel to maintain the bitingedges of the teeth formed thereon. The facing or sections 20 may be attached to thejaws in any preferred way whereby they may be removed when required. i

What is claimed is z I 1. A wrench comprisinga handle'having a jaw at its outerend and comprising similar sections, each including a bar and a semi-cylindrical portion, an inner'jaw slidable between the bars of the handle, and

means located within the cylindrical portion of the handle for adjusting the inner jaw towards and away from the outer jaw.

2. A wrench comprising a handle consisting of similar sections; each including a bar and a semi-cylindrical portion, a fixed jaw at the outer end of the handle comprising complemental section's formed with therespective bars of the handle, an inner jaw i slidable between the bars comprisin .the

handle, and means within the cylinc rical portion of the handle for adjusting the inner jaw towards and away from the outer aw.

ing similar sections,'each section including a bar, a semi-cylindrical portion andaijaw portion,-=the jaw and semicylindrical portions of the bars coming together and the remainder being spaced apart, a shank .between the handle sections, a jaw "pivotally mounted vupon the outer end of the shank, a'spring carried by and normally :eierting 3. A wrench comprisinga handleembodya pressure upon the pivotal 5mm hold itat thelimit of its forward" piv'otalmovement.

4. .A wrench comprising-ahandle includiag iatemny' spaced and separable sections and having :ajaw at its outer end, a shank arranged between the spaced portionslof the handle, a ljaw pivotedtoitheashank and having recesses 3m tip positesides to receive the spaced portions of the han dlfsaidlrces'ses being widened'forwardly to admit of the jaw having a limited pivotal movement, and a spring between the ;pivotedjaw and shank to normally hold' the jaw at the limit of its pivotal movement.

.5. A wrench comprising,alhandlelconsist- I ing of similar sections; each [section includmg abar, a aw portion anda s'emi-cylin drical P01431011, the aw portions of the bars coming together and havi g a 'tongiue'f and groove :j-omtbetween them, ans-hank between the bars, ajaw pivotally mounted, upon the forward end of the shank, a spring ;.carried by and normally holding the'jawat'the limit of its fo-rWard pivotal movement, and means within the cylindrical portion ofthe handle for adjusting the shank and holding the same in the required adjusted position.-
