The invention relates to wrenches and more particularlyto a ratchet wrench for use with interchangeable wrench sockets.

One of the objects of the invention is to provide a ratchet wrench in which the handle is slidably mounted on and revoluble relaj ect of this invention is to provide a quickly operable hand-ratchet arrangement associated with a long-handled wrenchwhereby the nut may be quickly turned up to a position requiring only a tighteningup by the long- The invention I eral features hereinafter set forth and more particularly defined by claims at'the'conclusion hereof. v 2 In the drawings Fig.1 is a side elevation view of a ratchet wrench embodying the invention showing it associated witha longs handled ratchet wrench whose handle is broken away; V Fig. 2 is a vertical sectional view ofthe wrench embodying. the invention; I Fig. 3 is a detail sectional View taken on the line 3'3 of Fig.1. h

In the drawings the numeral 4 designates the squared-portion of the shank, 5 a tubular portion of the shank and6 a flange forming a stop shoulder 7. V r

The tubular portion 5 isslidably and ro- 4 tatably mounted in the bore 8 of a tubular handle 9 having a knurled outer surface 10 and a spring 11 is interposed between the end of the bore 8 and the top of said shank. An

annular groove 12 is formed in the shank and' cooperates with a 'pin 13 mounted in said handle and projecting in said bore I 8 and groove to limit the extent of reciprocatory movement ofthe handle and hold the parts a in assembled relation with preferably a slight H tension of the spring 11 which therefore acts to normally-move the handle to, its upper pofurther consists in the seve therewith rlieses s ifig -ggiessea tans sition.

'said portion 18 being,

r to rapidly turn WVith the wrench 19 applied to the squared portion 4, as shown,

given a partial turn on each reciprocation the nut with which the socket 17. .is engaged down to a tightening position,

the pawlsf of the wrench 19 permitting this movement. lVhen thus brought to this position the ratchet wrench 19 is then operated in the; usual manner to progressively turnthe shank 4 and the socket 17 and only a few movements of this wrench 19 are required to securely tighten the nut. Thus time and labor are saved. in manipulating and tightening up nuts whose position is such as to necessitate the use of a ratchet wrench. In some instances the wrench 19 may not be used and under these conditions the rapid ratcheting action of the handle 9 brings the nut' to the desired position where it may, if necessary, be tightened up with a-separate socke wrench or with an ordinary wrench.

I desire it to be understood that this invention is not :to be limited :to any particular in screwing up a nut the handle 9 1s successlvely reclprocated and 4. In a wrench, the combination with a wrench socket engaging shank, of a tubular handle axially slidable in said shank, a s herical projection on said shank, there eing notches conforming to said projection in contour in the peripheral edge of said tubular handle, and spring means for normally disengaging said notches from said projection.

' In testimony whereof, I aifix my signature.


form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as iny invention is: a w 7 "1. In a device of the character described,

the combination with a wrench socket-engag- 7 ing shank, anaxially ratcheting handle associated with said shank, and horizontally ratcheting .wrench of the lever type having 7 a socket portion detachably secured to said 7 1 shank -2. In a socketiwrench, the combination with a shank adapted for detachable connection with interchangeable sockets, a tubular (handle slidably and rotatably mounted for axial association withisaid shank, a ratcheting connectionlbetween said shank and said tubular handle responsive to relative axial 1 movement therebetween, and a lever type wrench operatively connected to said shank i for the purpose set forth.

.- -3.: In a socket wrench, the combination with ashank having a polygonal part for de-.

I tachable connection with interchangeable wrench sockets, of a lever type socket Wrench ratcheted to said shank normal to the axis thereof, a tubular handle slidably and rotatably mounted on said shank, and an axial 'ratchetlng-connection andsaid shank.
