RATCHET-WREN'CH.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Application filed November 29, 1913. Serial No. 803,780.

To all whom it may concern Be it known that I, GEORGE C. REID, a citizen of the United States, residing at Labonte, in the county of Converse and State of WVyoming, have invented new and useful Improvements in Ratchet-Wrenches, of whichthe following is a specification.

This invention relates to improvements in that form of wrenches in which an oscillatory handle having a spring pawl or dog cooperates with the shank of a wrench head which is pivotally connected with the said handle in such a manner as to sustain the wrench head at a desired angle with relation to the handle.

Another object of the invention is to provide a wrench of this character which has its handle centrally bent to provide right angular members which have their ends forked and to pivotally secure within the said forked ends the segmental shanks provided upon wrench heads, spring pressed dogs being arranged between the forks and cooperating with the segmental shanks of the said wrench heads, while a slidable latch is employed to assist or cooperate with one of the dogs to engage with the shank of the wrench head to effectively lock the said wrench head against movement.

With the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claim.

In the drawings: Figure 1 is a perspective view of a wrench constructed in accordance with thewpresent invention, Fig. 2 is a central longitudinal sectional view through the end of the wrench having the stock of its wrench headed provided with ratchet teeth, Fig. 3 is a similar sectional view illustrating the wrench head swung and having the end tooth of its stock engaged by the dog or pawl, Fig. 4 is a longitudinal sectional view taken through the opposite end of the wrench showing both the pawl and locking member in engagement with the notches provided by the stock or shank of the wrench head, Fig. 5 is a similar sectional view with one of the corners of the pawl or dog contacting with one of the end teeth of the segmental stock of the wrench head, Fig. 6 is a transverse sectional view on the line 6-6 of Fig. 5, Fig. 7 is a longi-- tudinal sectional view on the line 7-7 of Fig. 5, Fig. 8 is a detail perspective view of one of the dogs or pawls, and Fig. '9 is a similar View of the sliding lock or latch member.

The improvement includes a handle 1 which is centrally bent or twisted to provide longitudinally extending right angular portions 3 and 4;, the ends of the said angular portions being slotted or forked providing spaced side members 55 and each of the forked ends is provided with an opening 6 to receive a pivot 7 whereby the segmental shanks 8 and 9 respectively of the wrench heads 10 and 11 respectively are pivotally secured within the opposite forked ends of the handle. The wrench heads 10 and 11 respectively are provided with transverse slots or openings 13 and 14: respectively for engaging with objects of different sizes or of different cross sectional diameters. The shank 8 is formed upon its periphery with a plurality of teeth 22, the said teeth comprising straight shoulders and angular connecting portions between the shoulders, and the periphery of the saidshank 8, adjacent one of its ends is formed with a smooth or uninterrupted surface 23 which terminates in a shoulder 24L.

Pivoted between the membersprovided by the forked end of the portion 3 of the handle is a spring pressed dog 17 the same having one of its ends provided with a head 20, the said head having an ofiset or projecting portion which is adapted to engage with the teeth 22. The body 26 of the dog 17 has its corner, adjacent its pivot, contacted by a spring 28 which is arranged within a longitudinal slot 27 in the end 3 of the handle and which is secured within the said slot. The end of the dog 17 opposite that of its corner 16 which is engaged by the free end of the spring 28 is provided with a lip 25 which, when the device is in the position illustrated in Fig. 3, is adapted to engage with the shoulder 24.

The segmental shank 9 of the jaw 11 is provided with peripheral transverse depressions 29, a portion of said shank being uninterrupted, as indicated by the numeral 30, and the said uninterrupted surface terminates in a shoulder 31.

The numeral 18 designates the dog which is arranged between the forked end of the portion 4 of the handle 1, the said dog being substantially similar to the dog 17 including a laterally extending head 20 having its curved outer face milled or serrated, as

at 21 and being provided with a toothed extension 32 which engages within the transverse depressions 29. One of the corners, 83, opposite the pivotal engagement of the said dog to the forked end of the handle is contacted by aspring 34:, arranged within a groove or channel similar to the arrangement of the spring 28, and the opposite corner of said dog is formed with a tooth 32 which, when the shank of the wrench head 11 is in one position, is adapted to engage with the shoulder 31.

The numeral 36 designates a slidable latch, the same comprising a substantially rectangular member and being provided upon its inner face with a longitudinally extending lug or enlargement, the side walls of which being beveled or dove-tailed to be received within similar slots or depressions in the inner faces of the forked end of the portion 4 of the handle. The inner face of said member 36 adjacent one of its ends and upon its outer face is formed with a finger hold 42, and upon its inner face diametrically opposite the said finger hold with a transverse, substantially V-shaped lip All. One

" of the edges of the portion 4 of the handle is formed with transverse depressions 39 and 40 respectively, and the lip or catch portion 41 of the latch 36 is adapted to be received within the depression or notch 39 when the said latch is moved to engage within one of the transverse depressions 29 of the shank 9 of the Wrench head 11, or when the saidlatch is adapted to engage with the shoulder 31. Likewise the notch 40 is adapted to receive the lip 41 when the latch 36 is moved out of operative or engaging position with the shank of the wrench head 11. By reference to Fig. 4 of the drawings it will be noted that the portion 31 of the wrench is brought into contact with the ver face of the sliding latch'36 opposite its longitudinal lug 37 when the said latch out further detailed description.

Having thus described the invention, What I claim is: i

I A wrench having a forked end, a Wrench head having a segmental shank pivoted between the arms of said forked end, thesaid shank being provided with peripheral teeth and with a smooth surface which terminates in a shoulder, a dog pivoted between the saidforked end and having a head and one of its corners formed with a tooth, a spring art'to which such invention appertains withfor holding either the head or the tooth in; I

engagement with the periphery of the shank, a sliding latch member, said latch member including a spring element having its body-provided with a longitudinal lug which is provided with beveled sides that are adapted to be received in beveled ways between the forked members at the end of the wrench, said latch having one of its edges provided with a transverse lip, and

one of theedges of the wrench being pro-' vided with spaced depressions to receive the said lip' and to sustain the latch either in contact with the dog and in engagement between two of the teeth or the shoulder of the shank of the wrench head or out of engagement with the said teeth of the shoulder of the said shank.

In testimony whereof I afliX my signature in presence of two witnesses. V

GEORGE O. REID.
