It follows, therefore, that the operator has no disengaged hand for holding or feeling the object or workpiece and .manipulating and locating the jaws into requisite Patented July 19, 1 949 SUCH AS CASTRATORS, TATTOOING'FOR- CEPS, PLIERS, AND 'rnamrm I I Arthur John Muter, London, England Application April 26, 1948, Serial No. 23,258 1 In Great Britain May 8, 1947 2 Claims.
This invention has reference to improvements in pivoted-handle tools for gripping, crushing, cutting and perforating such as castrators, tattooing forceps, pliers, shears, pincers, surgical forceps and cutting instruments, and the like, and is directed more particularly, although not essentially, to tools and instruments of this class having comparatively long handles needing the use of both hands to apply the final pressure when the jaws have been closed together.
In tools of this class, especially of the latter kind, the handles are often constructed to open to a very obtuse angle (of the order of 130 or thereabouts) to one another when the jaws are fully parted for application to the object or workand it has been found imone hand position simultaneously with closing together the jaws in a preliminary gripping and correctly located position.
The object of the present invention is to enable the handles to be closed together or substantially so with one hand, leaving the other hand free for necessary preliminary operations during this closing process. The disengaged hand can then be brought to the handles for completing the final operation of the tool which may involve the fullest possible pressure of both hands on the handles. One very useful application of the invention is to abloodless castrating tool designed to crush the spermatic cord, where it is necessary to feel the testicles to locate the cord region and place the blunt-edge jaws one on each side of the cord, while at the same time gradually closing the jaws together on the scrotum. At this juncture the scrotum will be preliminarily gripped at the correct cord region and the final crushing pressure is applied. The invention permits a single operator to perform operations of this character.
In order that the said invention may be readily understood, an embodiment thereof as applied to a castrating tool will be described in greater detail, as an example, with the aid of the accompanying drawings wherein:
Figure 1 is a front elevation, jaws closed; and
Figure 2 is a perspective view with the jaws partly closed.
The precise construction of the jaw end of the tool is not material to the invention so long as it is designed to perform efliciently the operation for which the tool is intended. As applied to a castrator there is employed a pair of castrating jaws l and 2 which would respectively have blunt parallel working edges 3 and 4, one of said jaws 2 terminating in a beak part 5 projecting towards and, when closed, lying over the end of the opposite jaw l as seen in Figure 1. Such a beak would hook around the far side of the scrotum when the cord region has been correctly located between the operative edges 3 and 4 of the jaws.
According to the essential feature of the said invention one of the handles 6 of the tool is provided with a fixed auxiliary handle I which extends inwards at 8 from as near the common pivot 9 of the two handles as possible, and then is directed outwardly away from the pivot 9 to lie between the usual pair of handles 6 and I0.
In the illustrated embodiment this auxiliary handle 1 is of curbed trigger form to constitute a comfortable grip when one hand embraces it and also the opposite handle ID as seen in Figure 2 (leaving free the usual handle 6 from which the auxiliary handle projects). In short, a single hand, which could not conveniently and operatively grip both usual handles when they are opened wide, can comfortably grip both the auxiliary handle and the opposite one so as to bring together the jaws for preliminary location and light gripping, such as approximately into the position shown in Figure 2. The grip of this hand can then be removed from such a position to grip the free handle 6 alone, while the hitherto disengaged hand can be brought to the other main handle ill in order that a concluding finishing pressure may be applied by both hands. Such a trigger-like auxiliary handle 1, when the main handles have been brought together as in Figure 1, lies snugly in the crotch of the two handles 6 and In, and its curve or other shape is made so as to conform and align with the inner edge of the opposite main handle; the main handies, of course, are still partly separated, even when the jaws are fully closed, to allow knuckle room (as in Figure 1).
The auxiliary handle 1 may extend outwardly in the longitudinal direction for any requisite distance, but for most purposes and uses it need extend only sufiiciently for the thumb of the operator to be hooked on it, and suitable proportional dimensions are clearly seen from the drawings.
The common pivot 8 between the main handles may be brought near to a line drawn between the pivots H and I! by which the subsidiary operation levers l3 and H are attached to the handles so that the final pressure on the handles forces the common pivot 9 past dead centre making a locked closure. 7
The bases of the Jaw elements I and 2 are slidingly l "!?!i t e emen a th auxiliary leyi's'lfl ma 4 forhafi'nofiart of the present invention.
