ELMER E. HILLIKER, OF KEARNEY, NEBRASKA.
CARRIAG E-WRENCH.
SPECIFICATION forming part of Letters Patent No. 607,436, dated July 19, 1898. Application filed December 23," 1897. $erial No. 663,190. (No model.)
To aZZ whom it may concern:
Be it known that I, ELMER E. HILLIKER, of Kearney, in the county of Buffalo and State of Nebraska, have invented certain new and useful Improvements in Carriage-Wrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
The object of the present invention is to provide an improved carriage-wrench which will tightly grip the spindle-nut and securely hold the same while being removed and replaced, as when oiling the vehicle,thus avoiding direct handling of the nut by the operator and the soiling of his hands incident thereto.
The usual form of carriage-wrench barely secures a loose hold upon the nut, and the latter is liable to and frequently does drop from the wrench, thus making it necessary to pick up the greasy nut with the fingers. This invention being designed to obviate the objection noted by providing a wrench which will constantly maintain its hold upon the nut until released, the same consists in the novel features of construction and in the combination and arrangement of parts hereinafter fully described and claimed, and illustrated by the accompanying drawings, in which Figure 1 is a perspective view of my improved wrench. Fig. 2 is a plan view of the same, showing the position of the parts when engaging a nut, the latter being shown in dotted lines.
The main portion A of the handle is formed with head or enlargement B at its rear end, and formed therein are wrench-holds O of different sizes, as is usual in carriage-wrenches of this character. The forward end of handle A carries jaw D, which constitutes one-half of the nut-socket.
Handle A is cut away rearwardly from its forward end, and pivoted at its extremity to the rear end of this cut-away portion is stem E of the movable jaw part F, which when closed against jawD completes the nut-holding socket.
Lever G is fulcrumed at one end to the under side of stem E and is of sufficient breadth to overlap the under side of handle A, and over said handle portion and adjacent the fulcrumed end of the lever the same is formed with the curved slot H, which is eccentric to said fulcrum-point and which embraces headed pin I, projecting from handle A.
The jaws of the Wrench are readily opened and closed by manipulatingthe lever at its free end, and owing to the position of the curved slot with respect to the lever-fulcrum the lever constitutes a lock or clamp for securing the jaws in any desired adjustment, it being impossible by exerting pressure upon the jaws to either open or close them without manipulating the said slotted lever. When the jaws are closed, the lever lies flatly upon the under side of the handle and out of the way.
In use the wrench is opened and inserted over the carriage-nut and is then closed thereon by the lever, as will be understood, thus securing the wrench upon the nut and preventing the latter from dropping therefrom when the nut is removed from the spindle.
The wrench is preferably constructed of malleable iron and is made in different sizes, and the socket may outline a square or hexagon, according to the shape of the spindle-nut upon which the wrench is to be used.
My improved wrench does away with the necessity of soiling the fingers by handling the nut, and by being positively secured thereto its manipulation is greatly facilitated.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. An improved wrench comprising a handle part provided at one end with a jaw, a second cooperating jaw pivoted at its inner end to said handle, and a lever connected with the said handle part and with the jaw at a point outside of the pivotal point of the jaw, one of said connections being concentrically arranged for the purpose described.
2. An improved wrench comprising a handle having at one end a jaw, a cooperating jaw having an inwardly-projecting arm pivotally connected with said handle, and a lever I connected with the handle and with said arm at a point between the jaw and the pivotal point of the arm, said connection constructed to draw the arm and handle part together, or to separate them, substantially as described.
3. An improved carriage-wrench including a handle part carrying a jaw, a second jaw 00- operating with the first-mentioned jaw and having a stem part pivotally secured to the handle, and a lever fulcrumed to one of the jaw-carrying parts and formed with a camslot to embrace a pin on the other jaw-carrying part, substantially as shown and described.
l. An improved carriage-wrench including a handle part formed with a jaw, a second jaw cooperating with the first-mentioned jaw and having a stem part pivotally secured to the handle, a lever fulcrumed at its extremity to said stem and adjacent the fulcrum formed with the curved slot eccentric to the f ulcrumpoint, and a pin carried by the handle part, which is embraced by this slot, substantially as shown and described.
5. An improved carriage-wrench including a handle part cut away upon one edge and at one end carrying a jaw, a second jaw having a stem fitting in the cut-out portion of the handle and at its rear end pivotally secured to the rear end of the cut-out portion, and a lever fulerumed at its forward extremity to the under side of the stem, and adjacent said fulcrum-point formed with a curved slot eX- tending eccentrically to the fulcrum-point, and a pin carried by the handle part and extending through the lever-slot, substantially as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
