FIG I KYUJI NAGAMORI FIG.6.
BY 4345 K/MW ATTORNEY United States Patent 3,193,211 VISE Kyuji Nagamori, 63 S-chome Honcho, Kawaguchi-shi, Saitama-ken, Japan 7 Filed May 14, 1963, Ser. No. 280,224 2 Claims. (Cl. 269-181) This invention relates to an improved vise.
Generally in the vise, holding or releasing an object therein is achieved by rotating a vise screw. Therefore, when gripping jaws of the vise are to be opened or fully closed thereby, a considerable amount of screwing will have been made by hand. Thus it is very difiicult to carry out a quick opening or closing of the gripping jaws of the vise and this is utterly inefficient in handling. Meantime a number of different types of the vise, that is, the socalled quick gripping vise have been produced in the aim of removing such inconvenience. However, the conventional vises, although they might be able to open or close their gripping jaws in a quick manner, have such defects that prevent the gripping of an object securely due to the long travel of the parts provided in the range of tightening operation.
The present invention contemplates overcoming such disadvantages in the conventional vises or in so-called quick gripping vises.
A preferred embodiment of this invention is illustrated in the accompanying drawings in which:
FIG. 1 and FIG. 2 are perspective views showing the way of handling the vise of the present invention.
FIGURE 3 is a longitudinal section view of the vise.
FIG. 4 and FIG. 5 are perspective views on an enlarged scale of the essential parts of the vise.
FIG. 6 is an enlarged scale section view taken along the line VI-VI in FIG. 3.
FIG. 7 is an enlarged scale section view showing the turned-to position from the original position of the part in FIG. 6.
With 1 is shown a stationary gripping jaw and 2 is a gripping jaw provided on a slide 5. 3 is a vise screw to move the said sliding jaw 2 forward and backward. 4 is a handle. 5 is a sliding part. 6 is the guideway in a stationary part. C represents an opening between the two gripping jaws.
The steps of handling will be explained first, leaving aside the structure thereof which structure is mentioned hereinafter. In this way, characteristics of this invention will be outlined in a more understandable manner.
To widen the opening C in a quick way, turn the handle 4 through approximately 360 in the direction of arrow A1 as shown in FIG. 1 until the handle 4 is positioned upright and then, in this position, pull the handle in the direction of arrow A2, allowing the sliding part with the gripping jaw 2 to move in the same direction. In this way, the opening is widened between the gripping jaws 1 and 2.
Now place an object W in the opening C and move the handle 4 while being upright in the direction A3 until the sliding gripping jaw 2 contacts the object W. Then turn the handle 4 approximately a quarter of a circle in the direction A4 and thereafter screw the handle 4 in the direction A5 until the object is held tightly.
For releasing the object from the vise, turn the handle 4 in the direction A1 and thence pull the handle in the direction A2 as shown in FIG. 1. Thus the opening between the two jaws is widened allowing the object to be released therefrom.
From the above explanation of the steps of handling this vise it may be realized how much more easily this vise can be handled.
The mechanical structure of this vise is as follows:
Referring to FIGS. 3-5, a pair of half nuts 7 and 7 and a cam 8 are mounted on the axis of the said vise screw 3 on the stationary part. Asshown in FIG. 3, when the said half nuts 7 and 7 are in retracted relation to each other, the vise screw 3 is engaged therebetween. In this condition, the vise screw 3 accompanied with the upper jaw 2 in the sliding part is moved forward by rotating the vise screw 3 in the direction A5.
In FIG. 3, reference 9 represents a supporting frame which is secured to a table or bench with holding down bolts 9. The stationary upper gripping jaw 1 is integrally joined to this supporting frame 9. Also 10 represents a guide in a pair of half nuts '7 and 7 and 11 is a coupling bolt by means of which the upper half nut 7 and the lower half nut 7 are constrained to face each other. 12 is a coiled spring whereby the upper half nut 7 and the lower half nut 7 are biased towards each other. The earn 8 is interposed between the half nuts in the registering holes of the upper and lower half nuts, 7 and 7 By turning the said cam 8, the half nuts are closed or opened, in consequence of which these nuts engage or disengage the vise screw 3.
In the center of the cam S, a free wheel mechanism is provided. That is, a boss 13 (see FIGS. 5 and 6) is slidably inserted in the cam 8 and between the said cam 8 and the boss 13, a spring 15 with a pin 14 at its end is interjacently attached. This pin 14 is to be engaged with or disengaged from a catch 16 which is provided on the cam 8.
In FIG. 6, when the boss 13 is turned in the direction A4, the cam 8 is also turned in the same direction, while the boss 13 is turned in the direction AS, the cam 8 does not turn.
When the cam 8, in the position as shown in FIG. 6, turns through its position coincides with that shown in FIG. 7 wherein the half nuts 7 and 7 open againsk the force of the spring 12. The boss 13 has a key 17 along the inner surface thereof which slidably fits a groove 18 provided along the axial direction of the vise screw 3. This key 17 engaging the said groove 18 of the vise screw 3 enabies the boss 13 to turn as the vise screw turns, where the vise screw 3 itself moves forward in relation to the boss 13.
In particular, with reference to FIG. 6, when the said vise screw 3 turns in the direction AS, the boss 13 is turned too in its own position, but this is not moved either forwardly or backwardly whilst the vise screw alone moves forward, hence the latter is engaged with the half nuts 7 and 7 The vise screw 3, when in the position shown in FIG. 7 may be either pulled or pushed in respective directions A2 or A3 independent of the boss 13 and key 17.
With thehandle 4 attached to the vise screw 3 at its end, it is preferred that the line LL on the cam 8, that is taken between the crests of its ends, be kept substantially parallel to the handle 4 in upright position. This is because the rotary position of the cam 8, being inside the housing as illustrated in FIG. 3, is not noticeable, nor is it possible to make sure that the half nuts are fully open or closed. However, by positioning the handle 4 as explained above, the rotary position of the cam 8 can always be known.
In the present invention as disclosed above, the opening C can be quickly regulated. Further, this device needs no special handle in operating the half nuts 7 and 7 Hence such operations as opening and closing of the half nuts, 7 and 7 or forwarding and backing of the sliding jaw 2 can be made even with a single hand. Accordingly, holding an object with one hand, all operations with the vise can be carried out with the other hand whereby the working efiiciency is greatly increased.
Iclaim: r
1. In a vise having a slidable gripping jaw adapted to be moved forwardly and backwardly in relation to a stationary gripping jaw, a pair of half nuts mounted'on the stationary jaw, a 'vise screw having a key groove; a cam between said pair of half nuts, said cam having convex crests at its outer ends, a free wheeling mechanism between the said vise screw and cam engaging said'key groove, and a handle attached to the outer end of the vise screw.
2. In a vise as defined by claim 1 wherein the plane I of motion of the handle attached to the outer end of the said vise screw is parallel substantially to a plane containing the crests of the ends of the said cam.
