Application filed November 11, 1324. Serial No. 749,256.
This invention relates to an improved wrench which is especiallydesi-gnedfor removing transmission cover and engine base bolts, the same being convertible for permitting it to be effectively used for rcmoving nuts from demountable "rims and the itate removal of the bolt and nut.
I propose to provide an improved arrangement of gearing for rotating the sockets at relatively diiferent speeds and I so construct the gearing as to permit the main driving gear to be shifted to an in operative position to throw thegearing out of use while the nutis beingstarted. Other'featuresand advantagesof the invention will become apparent from the following description and drawing.
In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same:
I Figure 1 is a side elevation, partly in section, of a wrench constructed in accordance with the present invention.
Figure 2 is a top plan view of the Wrench, and
Figure 3 is a detail view, partly in section and partly in elevation, showing the wrench converted to provide a common straight wrench.
. laterally extending arms 5 and 6 carried by a tubular bearing 7. At its top, this bearing 7 is provided with a substantially u-shaped portion 8, the arms 9of which serve in amanner to be hereinafter described. A secondrotary shaft 10 is 'rotatably mounted in the bearing 7 and this shaft is provided on'its lower end with a pinion 11,-the teeth of which are in mesh with teeth carried by a shiftable ring gear 12. The ring gear 12 is provided with a depending sleeve 13 which is slidably keyed ontheaforesaid shaft. 1. Interposed between the sleeve 13 and the crank handle 2 is a hand grip 14 which has a knurled surface and which is provided at its bottom withan-annular guide groove 15. A spring pressed sleeve 16 sli'dablyniounted on the crank handle. 2 and is provided with a finger 17 projectable into the groove 15. A retracting cord 18 is connected to the sleeve and in turn is connected to a pivotally mounted finger piece 19 on the crank handle audit, is obvious that by depressing the finger piece, thefinger 17 will be withdrawnfrom the groove 15 to permit sliding of the ring gear. Toyieldably resist sliding movement of the shaft 1, a coiled spring 20 surrounds the upper portion of the shaft between the bearing 5 and sockets 4.
Keyed to the upper portion of theshaft 10 and confined between the arms 9 is a gear 21 inter-meshing with another. gear 22 also confined between these same arms. The gear 22 however'is slidably keyed on a relatively short shaft 28 journaled in hearingopenings formed in the arms 9. The shaft 23 is provided at its lower end with a socket 24 opposed to the sockets i and adapted to engage a bolt head. Both of the shafts 10 and 23 are removably held in place-by cotter pins or their equivalent. It is yet to be pointed out that a pair of selec- Lively operated pawls '25 are pivotally mounted on ear 26 upon the U-shaped head 8 and are adapted to cooperatewith the gears 22.
As before indicated, the construction so far described. provides a novel arrangement for permitting substantially inaccessible transmission bolts to be readily removed. In carrying out this end, the opposed sockets 4 and 24 are moved apart to straddle the pair of flanges andthe upper socket 24 is engaged with the head of .a bolt, while the lower socket 4 is engaged with the nut.
Assuming that the parts are in the relation seen in Figure 1, the hand grip 14 is held in one hand and the crank 2 is turned with the-other hand, thus imparting direct rotation to the socket 4 through the medium of the shaft 1. After the nut is essentially loosened and started, the latch 19 is swung upon its pivot to retract the locking finger l7, and the ring gear is lifted up into mesh with the pinion 11. With the parts in this relation the crank is rotated and a speed wrench is provided.
As before intimated, the device is capable of being converted into a structure which may be effectively used for removing demountable rim nuts. lncarrying out this end,'the ring gear is again disengaged from the pinion 11 and is locked down in the position shown in Figure 1. An additional socket 27 is now brought into play and is placed upon the polygonal upper end of the aforesaid shaft 23. Then, as seen in Figure 3 a short polygonal coupling 29 is inserted in the opposed socket-s 4: and 24;. Thus, as the crank 2 is rotated the socket 27 is simul taneously rotated. Inasmuch as the frame structure forming the hearing may interfere with the operation of the Wrench at this time, I believe it advisable to provide means for maintaining these parts against movement. In carrying out this end I simply provide I a pair of guide loops 30 upon the bearing 7 and U-shaped member 8. In these I slidably mount a retaining rod 31 this has an offset intermediate portion 32 to permit the free end to be projected outwardly beyond the uppermost arm 9 to prevent the frame from swinging. The free end of the rod 31 may be positioned between the spokes of the wheel to accomplish this result.
1 In both embodiments of the invention the pawls 25 are engaged with the pinion 22 according to the direction of rotation. That is if it is desired to rotate the pinion 22 in one 1. In a wrench, a rotatably mounted shaft,
a slidably and rotatably mounted shaft alined with the first mentioned shaft, a rotatably mounted shaft disposed alongside of the first and second mentioned shafts, gearing disposed between the first and third mentioned shafts, a gear on the third shaft, a sleeve slida-bly keyed to the second shaft, a gear on the sleeve meshable with the gear of the third shaft,and a crank on the second mentioned shaft. 2 V
2. In a wrench structure, a rotatably mounted shaft, a slidably and rotatably mounted shaft alined with the first mentioned shaft, the adjacent endsof said shafts being spaced from'each other and adapted to have sockets or the like attached thereto, a rotatably mounted shaft disposed alongside of the first and second mentioned shafts, gearing disposed between the first and third mentioned shafts, a gear. on the third shaft, a sleeve slidably keyed to the second shaft and provided with an annular groove, a gear on the sleeve meshable with the gear on the third mentioned shaft, a crank on the second mentioned shaft, and a member slidably mounted on the crank and engageable in the groove of the sleeve. r
In testimony whereof I affix my signature.
