Application March 24, 1947, Serial No. 736,878

1 Claim. 1

My invention relates to a Wrench.

An object of my invention is to provide a wrench type of tool, which includes readily adjustable means whereby the wrench can be made to turn either in a clockwise, or counter-clockwise direction as desired by merely sliding a collar attached to the device forwardly and backwardly.

A further object of my invention is to provide means whereby the tool may be usedfor valve grinding or similar operations, or where the tool will rotate in both directions, by using the same collar.

A further object of my invention is to provide means for attaching a variety of tools to the end of the wrench, such as a screw driver, socket wrench, drill, or other tools employing a rotary motion.

A further object of my invention is to provide the above mentioned objects in a simple construction, which can be manufactured at a reasonable cost.

With these and other objects in view, my in vention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the tool in its vertical position,

Figure 2- is a sectional detail of the sleeve handle,

Figure 3 is a further detail,

Figure 4 is a detail looking at the rear of Figure 3,

Figure 5 is a detail showing the attaching clip attached to the unit, and

Figure 6 is a detail of the attaching clip.

I have used the character it to designate an. upper handle portion includin a pin 5 l received in an annular slot l2 which slot is formed in the extended portion I3 of the member It, the portion l3 being freely revoluble within the handle I0.

Rigidly attached at I5 to the portion 14 is the substantiall lengthened rod l6 which includes the spiral pitched threads ll. The member IE5 terminates at l8 in a U-shaped portion l 9 having the recess 28. Mounted within the recess 2?) is a member 2|, a pin 22 securing the member H to the portion l9. A small spring urged ball 23 is normally used to bear against a depression in the member 2| to lock it in place after the necessary tool is installed. The member 2| extends into the portion 24 which includes a further small sp ing urged ball 25 to firmly receive and engage the socket portion 25 of the tool to be used, and attached to the portion 28, is in one instance as shown, the socket wrench 2'! having the usual hexagon, or square depression 28 to properly engage a bolt or nut.

Other tools can be used with the arrangement, and as will be explained later, such as the valve grinding tool 23 having the valve grinding prongs 30, such being attached to the same type of socket 28, and being attached to the tool as above described. The character 35 indicates a twist drill, and the character 32 a screw driver, these tools being attached to the socket as shown.

A cylindrical handle sleeve 33- includes a pair of members 34 attached interiorly thereof, and at the ends thereof, by means of suitable screws 35, the members 34 including the ratchet teeth in opposed relation to each other as shown in Figure 2. A further member 3? is engaged at 353 with the pitchedspiral threads ll, and the member 31 includes ratchet teeth 35 which are adapted to engage the teeth 34. The member 3'! also includes an annular channel til.

Attached at M by means of screws or any other suitable method is an arcuate plate 42 which includes an opening 43 having the end notches i l and a central notch 45. A slidable keeper member (see Fig; 3) 46 is positioned beneath the arcuate plate 42 and includes the outwardly extending pin 4'! adapted to be received within any one of the notches 44 or 55. A spring id is attached at 49 directly to the member 32 and includes a portion 50 bearing against the member 46, yet allowing the member it to be placed in any desired position due to the slidable action of the member 46 with respect to the portion The member 46 includes a downwardly extending boss 5| which normally is adapted to be received within the channel 40 of the member 3i, and yet being of smaller diameter than the Width of the channel 40 to allow the ratchet to engage in one direction and release in the other.

The outer sleeve 33 also includes an opening 52 (see Fig. 4) which is directly opposite to the arcuate plate 42 or at the other side of the sleeve. The opening 52 is adapted to communicate with a further opening 53 which opening 53 is within the channel portion 46 and extends through the same. An arcuate spring member 54 in some cases as will later be explained is adapted to snugly engage the sleeve 33, and includes a pin 55 which passes through the opening 52 and into the opening 53.

The device is used in the following manner. In

3 operating the tool, the handle I I] is held with one hand while the sleeve 33 is held with the other hand, and this sleeve 33 is reciprocated back and forth along the rod l6. For obtaining rotation in either direction, the small pin 4'! is placed in either one of the notches 44. For instance, as shown in Figures 1 to 3 inclusive, the pin 41 has been placed in the lower-most notch 44. This correspondingly brings the lower teeth 39 of the ratchet in engagement with the teeth 36 of the lower member 34. Since the spiral threads I! of the rod l6 are engaged with the member 37; as the sleeve 33 is reciprocated back and forth along the rod I6, the rod IE will turn in one direction only during one part of the stroke but will be released in the other direction during the other part of the stroke. since the boss is slightly smaller as explained than the width of the channel 48 which allows the teeth 39 and 36 to become disengaged during the reverse action, but firmly grips and rotates the tool during the other stroke. It will be understood that the movement of the pin 47 carries the keeper 46 and the boss 5| with which to move the above mentioned member 31.

When it is desired to obtain rotation in the other direction only, the pin 41 is placed in the upper notch 44, bringing the upper ratchet teeth 39 and 35 into engagement, the reciprocating movement of the sleeve 33 causing the power rotation to be effected in the opposite direction as will be evident from the engagement of the members. In one instance, the power will be applied during forward motion of the sleeve and in the other instance during rearward motion.

By virtue of this construction any of the tools shown in Figure l with the exception of the valve grinder, can be used for turning clockwise or counter-clockwise as desired. This makes the tool readily applicable for a variety of desired condi tions such as right and left hand threads, etc.

For obtaining movement of the tool in both directions during slidable action of the sleeve 33, the pin 4'! is placed in the central notch 45 which carries the member 31 into a neutral position, or out of engagement with any of the ratchet teeth. Next, the arcuate spring member 54 is snapped on to the sleeve 33 so that the pin 55 engages into the openings 52 and 53, which correspondingly locks the member 31 against rotation with respect to the sleeve 33. Then, when the sleeveis thrust forwardly and backwardly along the rod 16, the engagement of the twisted threads I! with the member 3'! will cause the rod to rotate in one direction during one portion of the stroke and in the reverse direction during the reverse stroke. For this operation, the valve grinding tool 29 can This releasing action will occur be used, or any other tool requiring this type of motion.

It will now be seen that I have provided all of the various advantages mentioned in the objects of my invention with further other advantages being readily apparent.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.

I claim as my invention:

A tool of the character described, comprising a handle, a lengthened rod having a spiral thread thereon, a further handle engaged with said spiral thread adapted to move said rod in selected direction during reciprocating motion thereof along said rod, said further handle including means for controlling direction of power applied to said rod including a pair of stationary ratchet members attached to said further handle, a rotatable ratchet member received in said further handle member, said spiral thread engaged with said rotatable ratchet member, means for locking said rotatable ratchet member with either of said stationary ratchet members as desired to provide selected direction of rotation of the tool, including a guide plate engaged with said rotatable ratchet member, said further handle including notches, said guide plate including an extended pin received in any of said notches, end notches providing means for securing said rotatable ratchet against either of said stationary ratchets, one of said notches providing a neutral notch, said neutral notch providing means for maintaining said rotatable ratchet out of engagement with either of said stationary ratchets, means for securing said normally rotatable ratchet against rotation to provide rotation in both directions of the tool during reciprocating action of said further handle, said means including a spring clip adapted to snugly receive said further handle member, a pin attached to said spring clip, openings in said further handle and said normally rotatable ratchet for receiving said pin.
