WRENIGH.

.application filed November 7, 1921. Serial Ito. 513 s55.

T 0 all whom 'it may conce/m.'

Be it known that l, @HARLEY E. SUMMRS, a citizen ot the United States, residing at Nowata, in the county of Nowata and State of Oklahoma, have invented certa-in new and useiul Improvements in iiVrenches; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates ito an improved wrench which is especially', but notvnecessarily designed for use on Ford automobiles for removing or placing in position bolts and nuts.

The principal object of the invention is to generally improve upon tools of this class by the provision ot' one of extreme simplicity and durability which is practical, compact, conve/nient to handle, and easy to manipulate.

Another and very important object of the invention is to provide a wrench which enrbodies an angular head having means for engaging a bolt or nut, together with a handle on which said means is rotatable on an axis parallel thereto to permit it to be inverted or turned throughout an approxinia-te halt-circle so that it can be disposed and positively locked in diierent positions with respect to the handle to enable the tool to be used in limited spaces wherein the bolts or nuts are not easily accessible with the types ot wrenches now patented and marketed. Speaking specifically, it may be stated that this improved Wrench is primarily designed to ena-blc eective use thereof in removing and replacing the two headbolts which are disposed under the coil box and the fourth connecting rod bolts. Ordinarily, much time and patience is required in removing or replacing these bolts. However, by using` my improved Wrench, the task is ma-de comparatively easy.

Another object of the invention is to provide a novel Wrench wherein oneend of the handle is bent at right angles and then in parallelism t0 the body portion to offset this portion and to assist in enabling the desired'results to be easily accomplished, this handle being detachahly and rotatably connec-.ted with the rotary work-engaging mem-- to enable these parts to be positioned to obtain the aforesaid results or to permit these parts to be separated and conveniently carried in a tool box on the machine Without requiring much space. V

Other objects and advantages olif the invention will be apparent duringr the course of the following` escription.

ln the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure l is an elevational view of the improved wrench showing the handle and work-engaging' means in the position taken when removing?,- or replacing the aforesaid connecting rod bolts.

Figure 2 is a view like Fig. l showing the work-engaging devfice inverted to ena-ble convenient use of the tool in removing the head-bolts located beneath the coil Yoox.

Fig. 3 is a top plan View of Fig.' l showing` the formation of the hand-grip.

Figure 4f an enlarged detail sectional view taken through the Work-engaging means and portion of the handle showing the construction and arrangement of parts more clearly.

Broadly speaking, it will he recalled, as hereinbeiore briefly indicated, that the improved wrench comprises a work-engaging device including a detachable and rotatable socket member, means for permitting said member to be rotated in one direction or the other or held against rotation, together with a novel handle on which seid Work-engaging means is turnable oibiA an airis parallel thereto to permit said means to assume either ot' the positions indicated in Figs. l or 2 to permit convenient use oit the tool. in the places specified.

Referring to the drawingr in detail, it will be seen that the above named vv@rk-engagingf means is generally indicated by the numeral and the handle is designated yby the nu meral la. The holt or nut engaging deviceA l could be constructed in any suitable Way, but, by preference, it comprises a substantially l..sha.ped body 2 at the outer end ofI Which is located a removable lcombined socket and ratchet member 3. This member 3 disposed at right angles to the major portion ot the body 2 and is detachably connected therewith by means of a screw 4f which serves the additional function of a 5 journal to permit Jtree rotation of the member 3 with respect to the body. It may be stated here that this socket member is pret- 'erably removable because different bolts on automobiles of the aforesaid type are of different sizes and requires different sized sockets for engaging them. The inner en closed end ot' the member 3 is formed with teeth 5 and either one or the other of the dogs 6 are designed to alternately enga'e the teeth for rotating the member 'in one i rection or the other. A' coiled spring 7 is connected with the dogs and serves to hold them in engagement with the ratchet teeth. locking ring 8 surrounds a part of the body Z adjacent one end thereof and the widened part 9 ot this ringis adapted to alternately engage one or the other of the dogs for rendering' them effective or ineflective as the case may be.

The parts otl the Wrench so far specifically described are practically the same in construction as conventional ratchet Wrenches now commonly used and no claim is made to these details. As before set forth, the novelty of the invention resides in the employment of a different kind of handle and in the idea of mounting the werkengag'inganeans on this handle in such a way as to permit it to be inverted for accomplishing the ends pointed out. Although the connection between the handle' and dnvice l may be of some other construction, I simply provide the bore of the body 2 with internal screw-threads l0 and the outer end of the handle is externally screw-threaded as indicated at 11 and these threads 'are engaged with one another to detachably con neet the handle and body together and perrnit the latter to be rotated on the former for changing the relative positions. By carefully einn'nining` the sectional View shown in Fig. il, it will be seen that the screivthreaded end of the handle is equipped with substanially diametrioally dpposite depressions 12 and that a set-screw 13 passes transversely through the body is `adapted to have its inner end projected into one or the other of these depressions for holding tl e bodyin either of the positions disclosed in Figs. 1 and 2.

As before suggested and in order to enable a more effective use of the tool in limited spaces, the handle is bent laterally as indicated at 14 and the end 15 is agaln bent to extend in parallelism with the body portion of the handle. ln this Way, one end of the handle is ollset and experience has taught that byso shaping the handle, the tool can ing the aforementioned connecting rod or be much more conveniently used for rem0v' lessees head-bolts. Although. it is not absoluter'. necessary. the handle is formed fronrac vlindrical rod and this rod is bent upon itseltl as indicated at 16 and the end thereof brought to bear against thel body portion as indicated at 1T and a novel and desirable hand-grip is provided.

When it is desired to remove the connecting rod bolts adjacent the rear end crank Shaft bearing. the bolt-engaging device l is arranged in the position shown in Fig. 1. Of course, to permitthis the set-screw 13 must be first loosened and the entire device l turned as a unit around the handle for approximately a half-turn and the set-screw again turned in the opposite direction to position its inner end in the depression l2 which is then brought opposite it. When it is desired to use the tool tor removing the cylinder head-bolts which are located beneath the coil box and are ordinarily very dilicult to remove and replace. the bolt-engag'ing device 1 is again rotated on the handle to position it as shown in Fig. 2. The manner ot manipulatingr the locking ring and dogs for rotating the socket-member in one direction or the other is, ot' course, understood and need not be explained here.

By carefully considering the description in connection with the drawings, persons familiar with devices of this class will doubtless be able to obtain a clear under- Standing of the invention. Therefore, a more lengthy and detailed description is deemed unnecessary- Since probably the best results may be obtained with the construction and arrangement herein shown and described, this is taken as the preferred embodiment ot' the invention. llowever, I wish it to be under 105 stood that minor changes coming within the scope of the invention as claimed may be resorted to it desired.

claim:

1. A Wrench comprising a bolt-engaging 11o device including a body having' an internally screw-threaded bore, a set-screw passingr transversely through said body and having its inner end extending into said bore,

a handle having a screw-threaded portion extending into said bore and having its threads engaged with the first named threads, the portion of said handle'extending into said bore bein formed with approximately diametrical y opposite depressions into which the inner end of said setscrew is designed to extend.

2. A wrench comprising a handle formed from a rod bent at right angles intermediate its ends and then bent laterally with respect to the right angular-ly bent portion to dispose the laterally bent-portion in parallelism with respect to the body portion to offset one end of the handle to permit the tool to be conveniently used in places Which are Lawless eign? on an axis parallel thereto? and eoaoting means between 'alle lieail and enll of iofl ao positively hold the head in either of its ad justed positions. y

In testimony whereof, have hereunto set my hand.
