Apgl ication filed February 19, 1930. Serial No. 429,113.
his inv nti n relates o. wrenches at he ratchet type embodying among other characteristics means whereby the nut engaging p t on hereof will ro ate cQn inuQu ly due ng the ightening of the nut.
Another o j t o he i vention contemplates the p o ision and a angement f m ns upon the wren h wh reby the nut. en gaging portion may be operable in either d1? 10L reetion for tightening or loosening.
A additiona Obje of e inv ntion consists of multiple handles for the wrench he eby th nut engag g portion and wrench assemblyproper may be supported in position for use while the ratchet operation takes place.
More specifically stated the wrench is provided with pawl and ratchet connections for each of the handles whereby the latter may be actuated with equal eflect when desiring a reversal of the direction of travel of the nut engaging portion or may be Operated in unison where more power is required.
,With the above and other objects in View;
'- the invention further consists of the followtaken therethrough.

Figure 6 is a detail sectional View taken through a portion of the invention and illustrative of the connection taking place between certain of the parts thereof.
Referring to the drawings in detail where in like characters of reference denote corresponding parts, the reference characters 10 and 11 indicate the multiple handles, the former having a cup-shaped housing 12 upon ne end Wher as the hand e member 11 tee-.- minates to P ide slee e setti ii 3.

screw 29. The outermost projecting end of the shaft 27 is squared, as'at 30, to accommodate the innermost correspondingly shaped sleeve portion 31 of a socket or other wrench 32. A set screw 33, carried by the attaching sleeve 31 is designed for biting engagement with the squared portion of the shaft 27. The outer sides of the ratchet members 14 and 15 are providedwith radij 15 ally projecting ratchet teeth 34 exposed through openings 35 in the cup-shaped housing member 12 and the sleeve 13.
Pawls or dogs, such as indicated at 36, pivotally mounted for lateral swinging movement, as at 37, upon each of the handle members 10 and 11 and within boXings 38, are provided with multiple ends 39 designed for selective engagement with the teeth 3 of the ratchets. Extensions 40 carried by each of the pawls or dogs 36 are telescopically associated within the bores of tubular members 41 and engageable with compression springs 42 therein.
Studs or finger engaging portions'43 right angularly disposed upon the 'opposite ends ofth-e tubular members 41 are projected through curved slots 1-4 in the boxings 38 and by means of which the respective ends 39 of the pawls 36 may be manually shifted for yielding contacting engagement with the teeth of the ratchets.
' The ratchet members 14 and 15' are coupled as a unitary structure incident to the passage of fastening elements 45 therethrough.
It is obviously apparent that the shaft 27 will rotate continuously in either direction during relative oscillating or lateral shifting movement of the'handles'. The latter 'men-, tioned action being accomplished by the gearing mechanism associated in the manner shown and described in the foregoing. The ratio of the gearing connections may be such. 1 as to impart a "complete revolution to the shaft 27 incident'tothe movement of the particular handle'in a half circular movement.
v hen employed as a wrench, the tool can be applied to anut and held in place from'any angle-jwith one hand while quick 'operation is obtained with the other hand.
Continuous rotation of. the socket wrench,
I chuck or the like may be facilitated in View of the connection of the handle 10 with the squared end of the shaft 17 thereby causing bhaft 17 and gear 25 to turn with said handle;
The operator holding handle 11 stationary with one hand and applying the object to be turned, will move handle '10 outward, therer by turning shaft 17 and driving gear 25 left and the-movement of-the idler gears 24 will in turn cause the driven gear 26 totu'rn right thereby moving the object applied: in the direction desired; then the operator moves the handle 10 back or inward to engage the ratchet 14; and turn the cage andgears as one, causing the movement of the tool in the direction desired with both movements of the handle, making continuous movement. Handle 11 is free on the cage except for the action of the ratchet. The operator may hold handle 10 stationary and move handle 11 outwardly to engage ratchet 15. By so doing, the shaft 17, being held stationary by handle 10, the movement of the object applied is twice as great as handle 11 turns since it is turned both through movement of the ratchet member and gears. The return movement of the handle 11 does not impart any motion to the tool. I i
The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.
Having described the invention what is claimed is:
A ratchet tool of the character described comprising multiple handle members having ratchet members 'revolvably mounted thereon, means connecting said ratchet mem :bers to facilitate movement thereof as a unitary structure, pawls for each of the handles, a driving mechanism located within and common to both ratchet-members and operable eXteriorly thereof'bythe'handles and oneof the handles having direct driving connection with the mechanism and selective engagement with one of said ratchet members to impart continuous rotation to the handle." 7
In testimony whereof I affix my signature.
