Qwuwwtoz JOHN HELSTROM, OF MORRISTOWN, NEW JERSEY.
WRENCH.
Application filed November 3, 1913.
To all whom it may concern.
3c it known that- I, Jonx HELs'r-ROM, citi zen of the l nited States. residing at lllorristown. in the county oi Morris and State of New Jersey. have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
The subject matter ot the present inven tion is directed to new and useful improve ments in wrenches and has particular reference to those which are designed especially for use in coinicction with farm machinery and the like.
As its principal object, this invention aims to provide a wrench of the type specified consisting; broadly in a double-ended handle and a pair of rcvoluble wrench heads which are .lournalcd in the ends of the handle, the wrench heads being each formed with a plurality of nut receiving notches or jaws so that they may be employed in applying or removing nuts or any si7.e within a reasonable range.
A turtl er object is to provide a novel form of locking; dog whereby the revoluble wrench heads may be readily and easily looked in adjusted position.
- The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, desc 'ibed in the spccihcatii'in and then more particularly pointed out in the claims which are appended hcreto and form a. part of this application.
With reference to the drawings. wherein there has been illustrated the preferred enihodiincnt of this invention as it is reduced to practice. and throughout the se eral views of which similar reference numerals designate correspoiiding parts, Figure 1 is a perspective view of the composite tool; Fig. 2 is a top plan riew: and Fig. 3 is a detail view illustrating in longitudinal section the terminal of the wrench shank and one segment of the wrench head. disclosing particularly the manner in which the locking dog operates to .hold the wrench head in adusted position.
As most clearly shown in Fig.1. the preferred form of tnis wrench includes the body or handle member 10 in each end or which is journaled a revoluble wrench head as in dicatcd at 11 and 12.
The body or handle of the wrencln which will be hereinafter designated as an entirety by the numeral 10, is formed from a metallic Specification of Letters Patent.
Patented Jan. 11, 1916.
Serial No. 798,995.
bar of tempered steel, cast iron or any other metal which may be found efficient for the uses' to which the particular Wrench is to be put. This handle is formed in the nature of an elongated bar, the terminals of which are oppositely bent or offset and bifurcated as I at 13 and 1% to produce on each terminal a pair of spaced arms or forks l5 and 16. These members 15 and 16 are designed to receive between their adjacent faces the wrench heads 11 and 152 and are, for this purpose, terminally apertured in order to provide for the seating of the axles l9 and 20 on which the wrench heads are keyed as will be hereinafter more fully explained.
It may be well to explain at this point that the necessity for bending or offsetting the terminals of the handle 10, in opposite directions, arises out of the fact that it has been found to be inconvenient to apply the .wrench heads when they are longitudinally relatively thick and is centrally provided with an aperture 21 which receives the axle 1S). i-\t four approximately spaced points in the periphery of the disk there are formed )airs oi? notches which are individually designated in Fig. 3 by the numerals 22 and Q3,
24 and 25, 26 and 27, 28 and 29. As stated,
a pair of notches is formed at each of the four points in the periphery of the wrench head. it will be noted, upon reference to Fig. 1. that the notches of each pair are of a different size and that the pairs o1 notches ar also of a different size so that there are provided in the wrench head eight notches or nut receiving jaws of dillerent dimensions. In formin the pairs of notches, four relatively small notches are cut from one face. of the head. while four relatively large notches are cut from the other lace of the head.
It will thus be seen by reference particularly to l and 9 that each wrench head- The wrench head 11 consists esplurality of Substantially T-shaped segments consists in reality a ,a metallie disk which includes a central portion receiving the axle or pin 19 or 20, as the case may be, and a which radiate from the central portion and define between their adjacent edges pairs ot notches. Obviously also the notches included between the adjacent terminals of the.
head portions of the T-shaped segments are of less size than the notches defined by the adjacent edges of the stem portions of the said T-shaped segments.
The foregoing disclosures will be particularly appreciated when reference is had to Fig. 1 in which is illustrated, as previously stated, a wrench. stantially similar to the wrench head 11, above described, it will not be necessary to give a detailed description of this member, but it is desirable to mention that the notches or nut receiving jaws of the member 12 are allcof varying dimensions and are also of different dimensions than the corresponding elements of the wrench head 11. It will thus be seen that while the present wrench includes only two revoluble wrench heads, provision is made for the reception of these two and of nuts of sixteen diiferent in fixed relation. to the handle member. For
this purpose, therefore, there is provided in each wrench handle'lll a locking dog 30. Each of thesemembers 30 consists of an ordinary metal pin which is mounted for sliding movement in the longitudinally extending bores formed in the terminal of the handle as indicated at 31. Helical springs are interposed'between the inner ends of the bores and the adjacent terminal of the locking dogs so that the dogs will be constantly urged into engagement with the pcriphery of the wrench heads.
As a means for Withdrawing the dogs from lockingengagement with the wrench heads, each 'dog is equipped with a finger member 32, the shanks 33 of which extend through slots 34 which are formed in the handle and communicate; with the bores 31. The terminals of the dogs, are of course rounded or pointed so that they may move with ease into'the radial bores which are formed in the periphery of the wrench heads. It may be noted that these radial bores are four in perspective view of a complete gage in said bores of The wrench head 12 being subone-half inch ficing any of number in each wrench head, the the bores being obvious. v
Attention is now directed to the fact that the axis of each of the wrench heads is offset relative to the axis of the shank of the wrench, The work receiving notches in each of the wrench heads and the bores therein are arranged in staggered relation so'that each bore upon one side of each of the said-wrench heads isdiametrical'ly offset relative to the corresponding notch upon the opposite side thereof. It will now be observed that the dogs 30 are shiftable axially of the shank of the wrench to selectively enthe respective wrench heads so that-consequently, leverage upon the shank of the wrench'tendin' to rotate purpose of such an arrangement in one of the headswhen engage with the work will lie-communicated through the'said head in angularly disposed radial lines passing-through the axis of the head and the notch thereof engaged with the Work and the coacting dog30 respectively. Thus, at
no time will the leverageupon the wrench headbe communicated therethrough in diametric straight lines suchas would tend to break the Wrench head, its pivot, or shear the dog 30. Consequently, the peculiar arrangement disclosed of the several elements of the Wrench contributes materially to the strength and durability of the structure.
In reduction to practice, it has been found that the form of this invention illustrated in the drawings, and referred to in the above description as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desired to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrithe advantages of this invention, as defined in the appended claims.
What is claimed is 1'. A wrench including a shank having oil'set fork arms, a revoluble wrench head mounted between the said arms with its axis offset relative to the axis of the shank, said wrench head being provided upon one side with a work receiving notch and upon its opposite side with a socket diametrically ofi set relative to the notch, and locking means for the wrench head shif'table axially of the I shank, to project through one end thereof between said arms for engagement in said socket, whereby leverage upon the shank tending to rotate the head will be co1nmunicated through themhcad in angularly disposed radial lines passing through the axis of the headand through said notch and socket respectively.
2. A wrench including a shank havingoiiset arms, a revoluhle wrench head mminanrl ted through the ad will be communicu the 112 tween said arms win 1 its axis ()flset rela-
