PET-000K WRENCH.
Application mea July 20,1925. serial 110.414,81?.
To all who/m z'z. may coincer/n.:
Be it known that I, ROY GECIL MAJons, a citizen of the United States, residing at Reno, in the county of Washoe and State of Nevada, have invented a new and useful `Pet-Cock lVreneh', of which the following is a specification. i
rl`his invention relates to petcock lwrenches y stations, to open and close the oil gauge `petcocks by means of a wire rod having a pair of Hat U shaped metal lingers rigidly attached to one end of said rod.
The disadvantages inherent in this former method and device is that occasionallyan operator will forget to close the petcock with the result that the crank case oil will be completely drained from the crank case andl illustrating the wrench in position to be re-V moved from the petcock, or to be connected therewith to open the same.
Fig. 3 is a similar sectional elevation illustrating the parts of the Wrench turned to position to open the petcock.
In the preferred embodiment of this invention shown in the accompanying drawings, 1 illustrates the body of the wrench to which a sleeve 2 is screw threaded as illustrated at 3 and which body 1 presents a forward extension f1 provided with a hook 5 which is adapted to fit over the end 6 of the petcock 7. A handle 8 passes through a guide sleeve 9 screw threaded to the sleeve 2 and through a bore 10 formed in the lower end of the sleeve 2,7and lis `secured toa pair lof'U-shaped fingers 11, as illustrated at 12.
The body 1 presents a circumferential shoulder 13 against which the upper edge 14 of the U-shajped lingers 11 rests when the handle 8 is rotated to the position illustrated in Fig. 3 so that itv is vimpossible to remeve t-he wrench from the petcockvwhile the petcock is inthe open position as is illustrated in Fig. 3.
The Ahandle 15 the U-shaped lingers 11. A spring "16V is mounted upon the handle 8 between a wash.- er 1T retained in position by means of apin 18 passing through the handle 8 andthe walls of the sleeve 2 around the 'bore 10,l
land is so mounted that when the wrench is rotated to the position illustrated in Fig. 3, the spring is compressed and maintains the upper edge of the fingers 11 in engagement with the circumferentialy shoulder 13 on the body 1. i
The operation of this wrench is as follows: a v f L The body 1 ofthe wrench is hooked overl the end-6 -o-f the petcock and the handle 8 pressed forward until the U-sha'pednngers 11 slip over the handle 15 of the petcock which can then be turned or opened to the position illustrated in Fig. 3. It willbe obvious from Fig. 3 that when the petcock is opened, the wrench cannot be removed, without rotation of the body 1, due to the fact that the upper edge of the U-shaped fingers having been rotated to approximatelyL 90, vcannot re-enter the housing provided in the body 1. lVhen the petcock has been closed the spring 16 pulls the fingers 11 back into the non-operating position within the housing and the wrench can be removed simply by .lifting it olf the petcock.
In Figure 1, 19 illustrates the transmission case of the said certain type of automobile. The peteoeks are secured to the case in close proximity thereto. The hook 5 of the body 1 presents a flat edge shoulder 20 which engages the surface of the case 19 of the petcock fits between" when the said hook 5 is engaged with the departing rclaims; 1
exact, construction herein set forth which may, obviouslygbe varied in detail Without from the spirit of the appended Ielaimz'` i combination with a body adapted to be engaged with a petcock, means rotatably mounted in the body and adapted to be `en-V gaged With the handle of the petcock to rotate the sainetothe open position, which meansvvhen operated to rotate the handle `ed to be engagedy With a petcock, means "rotatably mounted inthe body and adapted to be engaged with the handle of the petcoclr to lrotate the same to anopen positioinvvhich ineans comprise a pair of lingers which when rotated to an open position-engage a portion of the body to prevent'r'einoval of the Wrench from the petcock when the said body isheld l stationary,
3. An article of the class described comprising a body adapted to be engaged With i a petcock, nieansrotatably mounted in the 30 body and adapted to be engagedwith the handle of thef petcock to rotate the same, `which means comprise a pair ot fingers which when rotated engage a portion of the body to prevent the removal ofthe Wrench from the' petcoclr, and means for yieldingly i maintaining the saidV fingers in engagement With the body when the fingers are rotated.
4. An article ofthe class described coma `prising a body, a pair of fingers rotatably .y mounted Withinl the body, a handle `secured i i I to the saidiingers,a chamber formed in the 1." In an article oit' the class described the body intol which the fingers are yieldingly urged when in the non-operating position,`
and means for preventing the fingersfrom beingurgedinto 4the recess when turned in the body.
y 5. The combination with a case, having a petcoclr secured thereto, of a. petc'oclr `Wrench `comprising a body adapted to be engaged with the said petcock, means rotatably mounted inthe body and adapted to,` be engaged with the handle oi' the petcock to rotate the same to an open position, and means on tliebofdy adaptedfto engage the case so as to prevent the removal 'of thesaid wrench from the said petcock` When the said petcock" is open.y Y
6. The combinationnfith a case, having a petcock secured thereto, of a petcoclr Wrench, having a body adapted to be engaged Vwith the said p etcock, means rotatablymounted vvithin the .body and adapted to be engaged with theliandle of the petcockV to rotate the same to an open position, and an engaging shoulder formed on the body and adapted to engage the said case to prevent rotation of the said body when the saine is engaged with the petcock.
