HUBERT zrNs, or wABnsso, MINNESOTA l VETERINARY CASTRATING' INSTRUMENT Application' med muy 31,
This invention .relates to an instrument adapted primarily for castrating animals such as cattle and sheep and itvaims to provide a novel means whereby the result may be accomplished without inflicting external wounds but rather to crush or sever the sper: matic cord and leave the testicles in situ Y where they will atrophy away and thereby lsepticaemia or infection. f
The more specific objects and advantages will become apparent from a consideration of the description following taken in connec# tion with accompanying drawings illus-v trating an operative embodiment.
In said drawings Figure 1 is a view illustrating the improved instrument in elevation, portionsof the same being broken away to disclose details,
Figure 2 is a sectional detail taken on the l y The bar-member 11 is slidable against the line 2-2 of Figure 1, v
Flgure 3 1s a cross sectlonal v1ew taken on `the lin-e3-3 of Figure 1,
Figure 4 is a cross sectional view taken on the line 4-4 of Figure 1,
Figure 5 is a view somewhat similar to Figure 1 but showing the parts separated,
Figure 6 is a sectional view taken` on theV line 6-6 of Figure l,
Figure 7 is a sectional view taken on the line 7-7 of Figure 1, and
Figure 8 is a detail perspective view of a portion of the operating lever.
Referring specifically to the drawings, 10 designates a relatively fixed bar member and 11 a relatively movable bar member, such members respectively having lateral or olfset jaws as at 12 and 13, respectively. Prongs 14 extend lforwardly from the jaw member 13 and beyond the same and are fastened in place by removable and adjustable bolts 15.
The portion of the jaw 13 through which the j bolts pass is triangular in cross section as .A knob or manual grip22is 1930. serial No. 472,111.
Vshown in Figure 2 and resilient blocks 16, which may be separate as shown or Vin a single piece as preferred, .are interposed between the prongs 14 and the jaw 13, thejlit of the prongs 14 on the bolts being rather loose wherebythe free ends of such prongs 14 may spread or separateas permitted and cushioned by the resilient blocks 16.
The jaws, in the openyposition, as .shown in VFigure 5, are adapted to be placed over"A the spermatic cord which is held with the left hand against' the outer wall of the scrotum and well above the testicle, the prongs 14receiving the cord between them Vand* the jaw 13y then being moved backwardly and 'forwardly in order to crushthe cord without danger of slipping or disengagement, against the jaw 12. Since the prongs 14 are-movable toward and away from-each other and cushioned by the blocks 16, they are automatically adjustable according to the thickness of the skin which they engage. i. Y
The bar member 1() is rigid with -a hollow handle portion 17, preferably `being 'fastened `tothe top'wall 18-thereof.f A guide of U- shape surrounds the bar members 10,4 and 11 and isriveted or boltedto the latter asat 19.
under surface of the wall 18 and has a guideV and operating member -20 which'lis slidable through the front vwall 21 of the handle 17 provided on the end of the member 20.
A trigger' orvoperating lever 23 is con- Unected to a U-shaped member 24 which is pivoted at 25 to the handle portion 17. The under surfaceof the bar 111s toothed or ser- Y rated as at 26 andthe sameis engageable by teeth 27 and 28, of p 'awls 29 and .30, respectively. Pawl 29 is pivoted at 31 to the lever-19 member 24 while the .pawl 30 is pivoted at 32 to the handle 17. Pawl 3() has an elongated memberor tine .33 which vis engaged by a crossmemberl 34- suitably fastened to the le` ver 24. -A-leaf; spring 35 fastened-to .the handle 17 constantlyV urges thepawl 30 into l.engagementwith the'cross member 34. The
`cross member or abutment '36.is provided on the Yhandle 17 forthe pawl A29 and aleafflg spring 37 secured to such handle lurges the pawl 29 against the abutment 36 and into locking engagement with the teeth 26.
As a result of the construction described, the lever 23 may .be thrown forwardly relatively to the handle portion 17 which results in disengaging the pawls 29 and 30 from engagement with the teeth 26. Thereupon the knob 22 may be engaged to movethejawmember 13 away from the member 12 in order to receive or engage thev spermaticcordbetween the aws. The bar 11 is then moved forwardly to engage the cordbetween--the j-aws 12 and 13 and prongs 14. Then by moving the lever 23 towards handle 17 by grippingit with the fingers of one hand, the other hand holding the jaws andy spermatic cord in position,the teeth 27 of pawl 29 will push jaw 13 against the cord and jaw 1'2 and by moving lever 2'3'backwardly and forwardly the pressure will be increased and the cord crushed, the tooth 28 of pawl 30 holding the bar from rearward movement during said movements of the lever.
It will be realized that my means of the present invention, the spermatic cord is secured or held against displacement before any pressure is applied to the cord in order to separate or crush it.
1t will be realized that after completing the operation relative to one cord, the instrument is disengaged and turned approximately one hundred and eighty degrees whereupon the same procedure as previously described, isfollowed with respect to the other cord.
Various changes may be resorted to provided they fall within the spirit and scope of the invention.
I claim asmy invention 1. In a castrating instrument, a pair of jaws to engage a spermatic cord, means on one of the jaws extending beyond the plane of engagement thereof with thecord, to prevent disengagement therewith, means permitting relative movement-of the first mentioned means to accommodate two thicknesses of the skinV between the jaws, comprising a pair of prongs, means securing the same to one of the jaws for movement toward-and away from each other and cushioning means against which the prongs operate.
2. Ainv instrument of the class described comprising a pair of bar members, jaws on said members, a handle to which one of said f members is secured on one side thereof, the second member being shdably mounted 1n the handle and movable relatively to the first member, teeth on the second member, a lever cooperating withV the handle, a pawl associated with said lever and with said teeth so that operation of the lever will move the movable member and jaw relatively to the other jaw, said pawl being disengageable from the second member to permit manual operation of the latter.
3. An instrument of the class described comprising a pair of bar members, jaws on said members, a handle to which one of said members is secured on one side thereof, the second member being slidably mounted in the handle and movable relatively to the first member, teeth on the second member, a lever cooperating with the handle, a pawl associated with said lever and with said teeth so that operation Vof the lever will move the movable member relatively to the other member and jaw, said pawl being disengageable from the secondmember to permit manual operation of the latter, a manually operable element extending from the second member andrthrough the handle to actuate said member alternatively with said lever, andl a guide carried by one of theimembers and surrounding the other memberbeyond the forward eX- tremity of the handle.
1n testimony whereof I aiiifX my signature.
