KEEFEB, LOS ANGELES, CALIFORNIA BATTERY TERMINAL PULLER Application filed October 29; 1929. Serial No. 403,236.
This invention relates to a pulling tool adapted for use in a great variety of pulling operations, but more particularly intended to be used to pull off battery terminals.
An object of the invention is to provlde a pulling tool which is furnished withimproved means for forcing the gripplng aws into contact with the object to be extracted or removed.
Another object of the invention is to provide a pulling tool having an improved combined traction element and means for operating the part which forces the jaws into the clamping position.
Among the valuable features of the invention are great strength and durability of construction combined with low cost of manufacture, dependability of operation, and but few and simple parts so constructedand arranged as not to get out of order.
Other objects and advantages may hereinafter appear.
Referring to the accompanying drawings, which illustrate what is at present deemed to be a preferred embodiment of the invention:
Fig. 1 is a side elevation of the tool showing the same positioned to remove a battery terminal, the terminal being shown together with part of the battery casing. In this view parts are shown in mid-section.
Fig. 2 is a view of the parts shown in Fig. 1 looking at the latter view from right tovleft.
Fig. 3 is a transverse cross section on line 35 33 of Fig; 2 showing only the central por- I tipn of the tool. v
Referring in detail to the drawings, the tool comprises a support or cross bar 5 having at each end'a bifurcated portion 6 and preferably provided at its lower side, as seen, in the drawings, with a central extension or boss Z. Upon said cross bar 5 are pivotally mounted the cooperating jaws 8 each of said jaws having at its lower end a gripping tooth 9 which is directed toward the center of the tool. Each of these jaws is embraced by a bifurcated portion 6 of the cross bar 5, being pivotally supported by a pivot 10 which extends through this part of the cross bar. Said cross bar 5, together with its boss 7 is provided with a vertical bore 11 through which extends the unthreaded lower portion 12 of the stem 13 which forms a combined traction element and means for moving the jaws to the gripping position as Will hereinafter be described. Said stem 13 isiprovided throughout a considerable portion of its length with screw threads 14 which are'in operative engagement with a cross-head 15 through which the threaded portion of said so I stem extends.
The cross head 15, as well as the bar 5, is provided at each end with a bifurcated portion 16, said portion 16 embracing the upper part of thejaws 8 and guiding their movements.
The upper portion of each jaw 8 is provided with an incurved cam-operable portion 17 with which cooperates a cam shoulder 18 formed on the upper part of the cross head 15 at each side thereof at the base of its bifurcated portion.
A compression spring 20 seated within a recess 21 is provided within each bifurcated part of the cross bar 5 near the upper edge of said bar. Said spring is located above the pivot 10 and tends to move the teeth 9 of the jaws toward the gripping position. Within the bifurcated part of the bar 5 for each end thereof is provided a shoulder 23 to limit the inward movement ofthe jaw teeth 9.
The upper end of the tool is desirably provided with a head 25 through which extends an operating bar 26.
The upper portion 17 of each jaw 8 is desirably provided with a shoulder or laterally enlarged portion 27 and an inside concavity 28, being thus constructed to keep it from marring the threads 14.
In the drawings the tool is shown in the gripping position engaging the terminal connector 30. of the battery 35. The lower end of the operating stem 13 is provided with an axial spur 36 to aid in centering the device in the operative position.
It will be seen that the pivot 10 of each of the gripping jaws is located nearer to the toothed end of said jaws than to the other end portions thereof upon which the cam element 18 operates. Therefore when the 9 cross head 16 is forced outwardly by the rotation of the screw threaded stem 13 it operates very effectively upon the jaws to cause them firmly to grip the desired object.
The operation will be readily understood from the foregoing description. The handle bar 26 not only enables the workman conveniently and effectively to rotate the stem 13, but also provides a convenient means for applying traction to-the implement. I
laims:
1. In a pulling tool, a cross bar having a transverse bore, an operating stem having a working fit within said bore, a pair'of grip-.
ping jaws pivotally secured to said crossbar in parallelism with said stem and one on each side thereof, said jaws having gripping portions on one side of said cross bar and cam operable portions directed towards each other on the other side of said crossbar, a head having a screw threaded engagement with. said stem and an engagement with said jaws to prevent its rotation upon said stem, said head being adapted for axial movement by the rotation of said stem to engage the cam portions of said jaws to move them to a gripping position, said cross bar having near one side thereof stop means to limit the approach of the gripping portions of said jaws toward each other, and compression springs mounted upon said cross bar to yieldingly hold said jaws in contact with said stop means.
2. In a pulling tool, a cross bar having a transverse bore, an operating stem having a working fit within said bore, apair of gripping jaws pivotally secured to said cross bar in parallelism with said stem and one on each side thereof, said jaws having gripping portions on one side of said cross bar and cam operable portions directed towards each other on the other side of said cross bar, a head having a screw threaded engagement with said stem and an engagement with said jaws to prevent its rotation upon said stem, said head being adapted for axial movement by the rotation of said stem to engage the cam portions of said jaws to move them to a gripping position, said cross bar having near one side thereof a bifurcated part provided with a shoulder between its bifurcations which forms stop means to limit the approach of the gripping portions of said jaws toward each other, and compression springs mounted upon said cross bar to yieldingly hold said jaws in contact with said stop means.
In testimony whereof I hereunto aifix my signature.
