Description
1951 w. .1. DOWLEY 2,994,55
NUT SPLITTING TOOL Filed Nov. 14, 958
INVENTOR ATTORNEY Patented Aug. 8, 1961 2,994,955 NUT SPLITTING TOOL William J. Dowley, Spring Arbor, Mich. Filed Nov. 14, 1958, Ser. No. 774,023 4 Claims. (Cl. 30-272) The present invention relates broadly to tools and in its specific phases to a device for splitting nuts.
When a nut becomes so badly rusted onto its bolt that it is frozen thereon, it is many times impossible to remove it with a wrench without danger of wringing off the end portion of the bolt. -It is therefore customary to split the nut with a cold chisel and hammer. However, this is often very difiicult, due to lack of space in which to so swing the hammer, to deliver really elfective blows to the chisel, and even where there is hammering space there is the danger of bending the bolt on which the nut is fastened. This is particularly true with respect to some of the nuts used in mounting automobile shock absorbers, and which are exposed to the elements which facilitate rusting. It was a recognition of this problem and the lack of any thoroughly satisfactory commercial device on the market for such use which led to the conception and development of the present invention.
Accordingly among the objects of the present invention'is the provision of a device aimed to overcome the above difliculty by providing a simple tool operable with a wrench and efiective to quickly and easily split the nut.
Another object is to provide an exceptionally strong and compact tool useable for splitting nuts.
A further object is to provide a nut splitting tool having a fixed cutting anvil and with a swivel ended screw for forcing the nut against the cutting anvil.
A further object is to provide a nut splitting tool wherein same has a splitting force delivering screw which is set at a small angle of inclination from the side of the nut to provide clearance for operating a wrench when the nut is up against the side of a frame or the like.
Still further objects and advantages of the invention will appear as the description proceeds.
To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and the following description setting forth in detail certain means for carrying out the invention, such disclosed means illustrating, however, but one of various ways in which the principle of the invention may be used.
In the annexed drawing:
FIGURE 1 is a top plan view of a preferred form of the nut-splitting tool of the present invention.
FIGURE 2 is a side elevation.
FIGURE 2 is a central longitudinal sectional view.
An elongated steel body 5 is provided, having a base portion with an integral preferably flat yoke 6 at one end of same to receive a nut 7 to be split. The body 5 has a longitudinal bore 8 which opens into one end of the yoke 6; and a nut-splitting wedge 9 is secured on the inside of the other end of said yoke with the cutting edge of said wedge in position to engage one facet of the nut 7. A steel pressure screw 10 is threaded into the bore 8 and is provided at its inner end with a swiveled head 11 to abut the facet of the nut 7 opposite to that which is to be split. The outer end of the screw 10 has an integral wrench-engaging head 12.
The bore 8 is so positioned as to dispose the axis of the screw 10 at a wide obtuse angle to the axis of the nut 7 to make the screw head 12 more accessible for engagement by a wrench. The included angle between the underside or base of the tool body portion and the axis of the screw 10, as seen in FIGURES 2, and 3, is generally in the range of 9 to 15 and a preferred angle for same is 12. Thus the wide angle is generally in the range of to 81 and preferably 78.
The wedge 9 preferably has an attaching shank 13 received in an opening 14 in the end of yoke '6 and, if desired, may be held therein by a set screw 15. To prevent any possible rotation of the wedge, the yoke 6 has a seat 16 in which the base of said wedge is snugly and non-rotatably received, so that the cutting edge of the wedge is substantially parallel to the longitudinal axis of the nut to the split when in splitting position.
To operate the tool, the screw 10 is backed out sufliciently to allow reception of the nut 7 between the swiveled head 11 and the cutting edge of the nut-splitting wedge 9. Then the screw is finger tightened and finally turned with a wrench until it draws the cutting edge of wedge 9 into the nut and splits it for easy removal.
While the specific construction disclosed is a preferred one, attention is invited to the possibility of making variations within the spirit and scope of the invention as shown and described. Also while the tool has been described, for ease of explanation, in the position shown in the drawing, the directional terms such as, base are not to be construed as limiting upon the invention since obviously the tool can be used in various positions.
Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the tool and combinations herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
1 therefore particularly point out and distinctly claim as my invention:
1. A nut-splitting tool comprising a body having a base portion with an integral yoke extending along said base at one end of the latter so as to surround a nut to be split, said body having a longitudinal bore which opens into one end of said yoke, a nut-splitting'wedge secured in the other end of said yoke to engage one facet of the nut, the cutting edge of said wedge being substantially parallel to the longitudinal axis of said nut when the latter is in splitting position, and a pressure screw threaded into said bore and having a swiveled head at its inner end to abut the facet of the nut opposite the one to be split, the outer end of said screw being pro vided with a wrench-engaging head, and in which said nut-splitting wedge has an attaching shank and said yoke has an opening receiving and securing said shank at the remote end of said yoke from the entrance thereto of said longitudinal body bore, and in which said yoke has a seat non-rotatably receiving the base of said wedge.
2. A nut-splitting tool comprising a body having a base portion with an integral yoke extending along said base at one end of the latter so as to surround a nut to be split, said body having a longitudinal bore which opens into one end of said yoke, a nut-splitting wedge secured in the other end of said yoke to engage one facet of the nut, the cutting edge of said wedge being substantially parallel to the longitudinal axis of said nut when the latter is in splitting position, and a pressure screw threaded into said bore and having a swiveled head at its inner end to abut the facet of the nut opposite the one to be split, the outer end of said screw being provided with a wrench-engaging head, and in which said bore is so positioned as to dispose the axis of said screw at an angle in the approximate range of 75 to 81 to the axis of the nut in position to be split, and at a small acute angle to the base of said body portion, and in which said nut-splitting wedge has an attaching shank and said yoke has an opening receiving and securing said shank at the remote end of said yoke from the entrance thereto of said longitudinal body bore, and wherein said yoke has a seat non-rotatably receiving the base of said wedge.
