'coan snvnnme IMPLEMENT 7 Application filed April 7,

This invention relates to improvements in implements of the type usually referred to as emasculatomes of the type shown and described in United States Letters Patent No. 1,7 54,241, granted April 15, 1930.

The object of this invention is to'produce an implement of the type mentioned which shall be'so constructed that it will be very rigid and therefore reliable in itsoperatio-n and which shall also be so constructed that it can be readily disinfected and cleaned. I

The general object of inventions of the type to which this improvement relates is to provide means for severing the spermatic cord of animals and also for severing the umbilical cord at birth.

Instruments of the type referred to are so constructed that they will sever the spermatic cord without cutting the skin in which it is enclosed so that this operation'can be aerformed without cutting and subsequently without loss of blood. V

In instruments of this type it is desirable to have the two jaws so mounted that when they approach, each other they form an oblique angle with each other in which the it outer ends of the jaws are closer than the inner ends, thereby producing a gripping action that will hold the implement "in place and prevent it from accidentallyslipping.

The above and other objects that may become apparent as this description proceeds are attained by means of aconstruction and anarrangement of parts that will now be de-. scribed in detail, and for this purpose reference will be had to the accompanying drawing in which the inventionhas been illustrated, and in which: V V

Fig. 1 is a side elevation of the implement showing the same in closed condition;

Fig. 2 is a side elevation similar to that shown in Fig. 1, but with the handles broken away and the jaws in open position;

3 is a section taken on line 3-3, e-

Fig. 4. is a sectiontaken on line 4-4, Fig. 2;and 1 Fig. 5 is a section taken on'line 55, Fig. 3, and shows the-construction of the adjusting means. 7

1932. Serial No. 603,762.

In the drawing reference numeral llindi cates a handle havinga hand grip portion'2 and an arcuate portion 3 which is curved on the arc of a circle. A jaw member 4 is provided at the end of the arcuate portion and the side 5 of the jaw adjacentthearcuate portion coincides with a radiusof'thecircle of which the-arcuate portion formsa part Although the edge 5 is preferably radial, it 7 is not absolutely necessar y that this should be so as the implement will function in sub; stantially the same manner, even' if this edge is inclined with respect to the radius in either direction, although such inclination must' be somewhat limited. i J

A second jaw member 6 is provided with a curved edge 7 whose curvature is the same as that of the arcuate portion?) and is adapted to fit against the latter. This jaw member has an edge 8 that is preferably radial with respect to thecurvature of the edge 7, but as explained in connection with'the edge 5, edge 8 may vary from the radial to the same extent as edge 5. a The secondjaw is provided on each side with a: groove 9-that is concentric with the curved surface 7 and attached to the 'arcuateportion of the handle are lugsthat have inwardly projecting portions 11 that extend into the groove '9f1n the manner shown more'clearly in Figx4l The lugs' 10 serve to hold the second jaw member in position adjacentthe arcuate sur- 7 face 3, but permits the j aw member to move with respect to the handle member. It will be apparent that if the curved surfaces 3,

and 7 are arcs of circles and if'th'e/edges 5 Y and 8 areradial with respect to these surfaces, then when the second jaw member" is moved .alongthe curved surface alts mo-,

tion will be the same as if it turned about a pivot located at the center-of; the arcuate surface 3. From this it will be seen that when the two jaws are in the position shown in Fig. 1, the edges 5 and 8 are parallel,but

if the jaw member 6 is moved away from jaw member 4, then the two edges 5 and 8 will thatthey intersect at the center of the are as; above explained. For'the purpose ofmoving the jawmember 6, alever l2 hasj-been become inclined to each other for'the reason component tending to rotate thelever 12.

Referring now more particularly to Figs.

1 and 2, it will be seen that whenthe handle 1 and the lever 12 arein the positionshown in Fig. 1, the two jaw surfaces 5 and 8 are parallel with each other and spacedi a short distance apart; It inightlbe mentioned here thattthis instrumentis not intended for cutting and therefore the jaws must always be adjusted so that they will not be brought into contact witheach other because'if this were doi1e,'it. would sever. the skinand'flesh interposed between them When the handle and lever are moved apart from each: other towards'the pesition shown w in Fig 2,, the jaw 6= Willi be moved away iiror'n 4,. but

will follow the curved surface 3:.v Since the.

pivot 11 moves in the are of a circle whose center iseat the vintersection ofthe: aws- 5 and 8 extended, it is evident the pivot16 slot 15 has been provided.

-J-S1ot'15 is so curved that when the jaws are brought to closed position against some resistance; then the pressure necessary will be'betwee n the convex side of theslot 15 and the pin 16 and by so forming thisslot that a line drawn through the pivot 16'andthrough the pivot 17 when the jaws are in closed position, will pass through the' center of curva ture'of'the slot, then a constructionis pro duced inwhich the leverage increases as the. jaws approach each other and inwhichthe jaws become practically locked when in the position shown Fig. 1, from which it will be seenithat with the partsadjusted in the manner idescribedand shown any-force tende ing to, separatethe jaws will not have any In order'topermit the edges of the jaws to bee-properly adjusted'so as-to obtain the most desirable results, an adjusting means has been provided which has been illustrated in Fig.5; From Fig. 5 it'will be seen that thejaw member his provided withv an opening'18; in which is located a circular plug 19. Plug'19 is provided with an eccentric opening 20throughwhich the pivot pin 1Textends It is evident that by turning thelp ltrg 19 in the hole 18, the relationship oi the edge Set the jaw can be varied with respect to the pivot 17 .T 1 Y For therpurpose of adjusting the plug 19 in the ripening 18,-jaw memberhhas been pro-- 1. The ends of members 14 project forward-v vided with two openings 21 that are Preferably radial with respect to the opening 18 and located in each of these openings is a threaded plug or screw 22. These screws have conical ends 23. The plug 19 is provided with conical depressions 24 into which the conical. ends 28 of the screws extend. In the form illussible by moving one of the screws outwardly and the otherinwardly, to effect a slight rotation of the plug 19, which is sufficient to elfect the required adjustment oi theedges 8- 'and 5 oi? the jawsr v 1 r From the above description it will 'be seen that the impleinentthat forms. the subject of this invention. is of a rigid construction and so formed that the j aws; as. they approach each other, are. closer together at the outside than atthe inside whereby a clamping action is obtained that serves to hold the implement in place during the operation. "lt will also be seen that by means ofthe construction shownanddescribed the leverage is greatly increased as the jaws approach each other this increase in leverage being dueto the straining ofthe toggle and also to the curvature of the slot 15. r V .f It is also desired to call attention atthis point to thefact that by removing the pivot pin l'Z thejaw 6 can be removed for cleaning 7 and it. is therefore possible to maintain this instrument in an antiseptic orsterilized condition with less amount of labor and care than is necessary with instruments that cannot be soreadilyseparated.

Particular attention is called to the fact that the two jaw surfaces .7 and}? have a movement relative to. each other, that is to say as. if rotated relativeto each other about the center of the arcuate suriace 3..
