Description

ERNEST T. FOSTER, OF WTNTERSET, IONA.
WHENGl-ll Specification of Letters "Patent.
Patented Aug. 15, 1995.
Application filed October 17, 1904. Serial No. 228,694.
To will whom it may concern:
Be it known that I, ERNEST T. Fos'rnn, a citizen of the United States, residing at VVinterset, in the county of Madison and State of Iowa, have invented a certain new and useful V french, of which the following is a specification.
The objects of my invention are to provide a wrench adapted for use in removing a particular form of nut and bolt forming a vehicleaxle and so arranged and constructed that the nut and the bolt will be removed from the axle simultaneously by the use of this wrench.
It is more particularly my object to provide a wrench for use in connection with a lock-nut for vehicle-axles which is in vented by me and for which I have made an application for Let-, ters Patent of even date herewith.
ltiy wrench is of simple construction and is adapted. for use on nuts of various sizes and in di'lierent ways, and it is so arranged that by simply turning the handle of the wrench a bolt which extends through the nut on a vehicle-axle will be unscrewed, and at the same time the nut will be drawn downwardly by the wrench as the wrench is being turned.
My invention consists in certain details in the construction, arrangement, and combination of the various parts of the device, whereby the objects contemplated are attained, as
' hereinafter more fully set forth, pointed out in my claims, and illustrated in theaccoxnpanying drawings, in whichltigure 1 is a sectional view of a portion of a vehicle-axle and a portion of the hub of a wheel with a locked nut thereon, showing in sectional detail my wrench and the way of attaching .it to the lock-nut for securing the lock-nut or removing it from the axle. Fig. 2 is an end view of the axle with the hub of a wheel thereon, showing a plan view of my wrench; and Fig. 3 is a detail perspective view of the outer end of my wrench.
Referring to theaccompanying drawings, l have used the reference-numeral 10 to indicate the handle of the wrench. This handle has a series of openings through it of different sizes adapted to receive bolts of various sizes, as in the ordinary wrench.
The reference-numeral 11 indicates the head of the wrench having an opening 12 extending through it. On the interior of the head of the wrench is a recess 13, communicating with the opening 12, which is slightly larger than said opening and is designed to form a circular shoulder 14:, against which the head of the bolt to be unscrewed rests. The head of this bolt also engages the sides of the opening13 while the wrench is being used. At the extreme outer end of the head of the wrench is a jaw 15, the body of which extends at right angles to the head of the wrench and has the extension 16 at right angles to the body of the jaw and substantially parallel with the head of the wrench. This extension is designed to engage an annular rim on the nut which is to be removed. At the opposite end of the head from the fixed jaw 15 is a pivoted jaw 17, which extends through the handle 10 and a slight distance from the opening 12 through the head. This pivoted jaw has the extension 18 extending outwardly from it and substantially at right angles to it toward the jaw 15. This jaw 17, with its extension 18, is designed to engage one side of the nut, while the jaw 15, with the extension 16, engages the side of the nut which is diametrically opposite. The pivoted jaw has a thumb-piece 19 extending away from the pivot 20, which holds the pivoted jaw 17 to the handle 10, and secured to the head 11 and resting against the thumb-piece 19 is a leaf-spring 21, which normally holds the pivoted jaw at its limit of movement toward the fixed jaw, so that after the jaws have been placed upon the annular rim of the nut which is to be removed the wrench is held in position relative to the nut by means of the spring 21 acting in conjunction with the jaws. in the use of my wrench it is necessary to have a slidingly-mounted non-rotatable nut 22 and a screw-bolt 23 passed through the nut 22 and into the axle upon which the nut is mounted in such a way that the head 2% of the bolt extends outwardly from the outer surface of the nut, and there must also bean annular riin 25 on the outer end of the nut 22, which is to be engaged by the jaws l5 and 17.
in practical operation the pivoted jaw 17 is swung to its extreme limit of movement away from the fixed jaw 15 by pressing outwardly on the thumb-piece 19. The fixed jaw is then slipped over the annular rim 25, and the ban dle of the wrench is moved inwardly toward the nut in such a way that the head 24 of the bolt 23 enters the opening 13 and rests against the shoulders 14 in the head of the wrench. The thumb is then removed from the thumbpieee 19, and the spring forces the jaw 17 into engagement with the annular rim 25 at a point diametrically opposite from the position of the jaw 15 on said wrench. Assuming that the nut is secured to the axle, the operator turns the wrench to unscrew the bolt, and as he does this the jaws l5 and 17 will slide around on the annular rim 25 of the nut, and as the bolt is unscrewed by the wrench the nut will be drawn outwardly and removed. The wrench will maintain the bolt and nut in position relative to each other while they are removed, if it is desired, by the operator, and by simply repeating the operation of removing the nut, except for screwing the bolt into the axle, the nut can be replaced and held rigidly in position to the axle by the use of my wrench.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is
1. A wrench capable of turning a bolt, comprising a handle, a head at one end of the handle, means for securing the wrench to the head of the bolt and rotatably securing the Wrench to a nut so that as the wrench is turned in one direction, the nut will be drawn outwardly, and as the wrench is turned in the opposite direction the nut will be moved in- Wardly.
2. In a wrench, a handle, a head at one end of the handle, a fixed jaw at one side of the head, a pivoted jaw at the other side of the head, a spring for normally holding the pivoted jaw at its limit of movement toward the fixed jaw, an extension on the fixed jaw extending toward the pivoted jaw, and an extension on the pivoted jaw extending toward the fixed jaw, for the purposes stated. 4
3. In a Wrench, a handle, a head at one end of the handle having an opening in it designed to receive the head of a bolt, and jaws connected with the head designed to engage a nut and hold the nut and bolt together while using the wrench and when the bolt and nut are removed.
4;. In a wrench, a handle, a head at one end of the handle, having an opening extending through it and a recess therein designed to receive the head of a bolt, jaws connected with the head, designed to engage a nut for holding the nut and the bolt together while the wrench is being used.
5. In a Wrench, a handle, a head at one end of the handle, having an opening extending through it and a recess therein designed to receive the head of a belt, a fixed jaw at one end of the head having an extension at right angles to its body portion, and a pivoted jaw secured to the head at a point adjacent to the handle, having an extension at right angles to its body portion projecting toward the fixed jaws.
6. In a wrench, a handle, a head at one end of the handle, having an opening extending through it and a recess therein designed to receive the head of a belt, a fixed jaw at one end of the head having an extension at right angles to its body portion, a pivoted jaw secured to the head at a point adjacent to the handle, having an extension at right angles to its body portion projecting toward the fixed jaws, and a thumb-piece on the pivoted jaw, for the purposes stated.
7. In a wrench, a handle, a head at one end of the handle, having an opening extending through it and a recess therein designed to receive the head of a belt, a fixed jaw at one end of the head having an extension at right angles to its body portion, a pivoted jaw secured to the head at a point adjacent to the handle, having an extension at right angles to its body portion projecting toward the fixed jaws, a thumb-piece on the pivoted jaw, and a spring for normally maintaining the pivoted jaw at its limit of movement toward the fixed jaw.
