NESBIT, JR., F BIINGHAH,
. $T'UD ENGE Application filed October 6,
My invention relates to stud wrenches.
n object of my invention is to provide a wrench which 1s adapted to engage with studs of various diameters, and is also adapted to turn a stud either clockwise or counterclockwise without change or adjustment of parts.
Another object of my invention is to provide a wrench in which the clamping force proportion to the resistance offered by the stud, and in which there is a maximum of gripping surface provided.
A further object of my invention is to provide a wrench having a minimum number of parts and which will not readily get out of order.
Briefly, my wrench comprises a tubular member adapted to receive a stud. A gripping member is pivotably mounted between a pair of ears which are formed on the lower end of the tubular member. The tubular member is slotted between the ears to permit the gripping member to engage a stud and is provided with means at its upper end to facilitate turning the tool when the stud is being mounted or removed from its companion part. The gripping member is provided at gripping surface having teeth oppositely inclined on the two sides of the longitudinal axis thereof. The gripping member is provided with a pair of pivot points, difierently spaced with respect to the ends thereof, one for each gripping surface, to adapt the wrench for a wider range of use.
Apparatus embodying features of my invention is illustrated in the accompanying drawings forming a part of this specification, in which: r
Fig. 1 is a view in side elevation wrench engaging a stud;
Fig. 2 is a sectional view taken along the line H-H of Fig. 1; and
Fig. 3 is a sectional view 2 and showing the gripping member mounted reversely to engage with a smaller'diameter stud than is shown in Fig. 2.
Referring to the drawings for a better understanding of my invention, I show a tubular member 5 having a pair of ears 6 and showing a taken along the 193D, fierial No. 488,828.
7 formed on its lower end. 'A gripping member 8 is pivotably mounted between the ears on a pivot pin 9 and extends into a slot 11 formed in the tubular member.
hen the pivot pin 9-is engaged in hole 13 formed near one end of the gripping member, it is adapted to engage with a large diameter stud 10. When the wrench is to be used to mount or remove a smaller diameter stud 15, the pivot pin 9 is removed and mounted through the hole 14 formed in the gripping member 8 nearer the end thereof than the hole 13 so that theiother concave gripping surface 12 maybe employed to engage the stud as shown in Fig. 3. The spacing of the holes 13 and 14 relative to the ends of the gripping member 8 provides a wrench having a wider range of use than would be possible if the gripping member 8 had onlyone gripping surface and one pivot center.
he provision of the concave gripping surfaces 4 with the oppositely inclined teeth 12 on the two sides of the gripping member provides means whereby there is a maximum of teeth engaging and gripping the stud to be tightened or removed.
The upper end of the tubular member 5 is shaped to accommodate a wrench, not shown, to facilitate turning. When the tool is used, the gripping member is turned about the pin 9 in a direction corresponding to the direction in which the stud is to be turned and grips the stud as securely as is necessary to overcome its resistance.
While I have shown my invention in but one form, it will be obviousto those skilled in the art that it is not so limited, but is susceptible of various changes and modifications, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set fiorth in the appended claims.
What I claim is: i
1. A $116 Wrench comprising a tnhnler member adapted. to receive e stud a pair 0i spaced eers iforined on one enfi of time tubular member, means defining a slot opening into the tubular member, a gripping member hering pivot holes therethrough near the enis thereof and spaced at relatively difierent eistances from the ends erfl extening into the slot, a detachable pivot pin ficr pivotebly mounting the gripping member between said ears in its remoter pivot hole from the slot, e concave gripping 'surr'ece iorrned on each end of the gripping member, anoi teeth formed on said gripping surfaces and extending ourwardly and oppositely on the two sides of the longitu dinei axis of the gripping member.
2, A stud Wrench comprising a tubular member having at one erfl e tooi grip and at the other enri a stud gripping means comprising a, laterally extended bearing, a grip plate having opposite ends thereof and having pivot hoies along the center line thereof, seidpivot holes being clifierentieliy spaced from sei toothe surfaces, 21 pin engaged in said. heerin and in the w there being a slot in said tubular member whereby the selected toothedsurface of the grip plate may enter and; swing about sai i pin in either direction across the bore of said tubular member to. engage end grip e sturi therein.
In testimony whereof Tl affix my signature.
