Application November 9 Claims.

The present invention: is particularly directed to andhas for its objects. the provisionof. improvements in the attachment deviceby' means of which the'shield is. more advantageously'applied as well. as in the improved design of the shield whereby. a. more effective protection against pick-outs is obtained.

More particular objects and advantages, together with the foregoing, will become apparent in the course-of thefollowing description and in the claims annexed-thereto, the invention consisting in the novel construction, adaptation, and combination of parts hereinafter described: and claimed.

curved inwardly. Aperipheral' flange reinforces the shield.=

In the structure disclosed in my prior patent, a common safety pin was employed with the pointed strand of the two pin elements being passed horizontally through the fatty rump of the fowl, the companion guard-carrying strand lying under the rump and connecting with the upper end of the shield. The shield itself was formed with its vertical medlan line disposed approximately rectilineally and, while the arrangement has operated in a highly satisfactory manner, a disadvantage which the present invention overcomes has been a tendency of the shield to incline rearwardly' from its pin connection due to the protrusion of the rectum-forming portion of the fowls body lying-below the hinge.

Asbest illustrated in Fig. 2, I form the upper extremity or that portion of theshield which lies adjacent the pin-connecting extremity curvilinearso that the median line or the shield at its point of intersection withthe lower edge lies in the approximate vertical plane of the hinge, the shield body inclining rearwardly therefrom with the upper curved endextending outwardly beyond therectalprotrusion. (Jo-active with this improved design of the shield, I have devisedan especially advantageous pin arrangement adapted to facilitate the attachmentof theshield to and: the removal of the shield from the fowl and U which additionally operates to obtain a more secure hinge connection in that movement of the pin about the rump-penetrating strand as an axis is prevented.

Referring to said pin, I form the same to a relativeU-shape to provide a pair of relatively parallel verticalv branch elements l5 connected at their lower ends by a horizontal arm element It, the arm being hinged in the eye-forming extremity of the shield's upper end and the vertical branches being pointed at their upper tips for passingthe same vertically through the fatty rump'oi the fowl, the branches being of a length to project above the rump and in their exposed ends at opposite'sides of 'each element providing notches ll. Said notches desirably are constituted wltha sharpjog at their respective upper limits and are formed by flattening the material. under pressure to express the same laterally whereby nodular extenslons l8 are provided which lie in the horizontal plane of the notches at each opposite edge or the same.

Adapted for reception over said exposed tips of the branch elements is a keeper formed from a rectangular blank of spring metalbent on its approximate transverse median line to provide a pair of limbs 2i diverging downwardly with the lower ends of the latter being brought inwardly and upwardly in the provision of companion meeting jaws 22, the blank providing parallel cuts in proximity to the side edges of one of the jaw-forming'terminals to form lateral fingers 23 which, as the blank is bent, are disposed to lie horizontally in a plane below that of the jaw whereby the fingers extend over and beyond the longitudinal vertical center line of the keeper and act as stops at each end of the jaws.

In using the shield, the pin branches iii are passed through the rump of the fowl and the keeper introduced as a guard over the exposed tips, the jaws 20 spreading to admit the branch elements and closing below the horizontal notch shoulders to lock the keeper in position. To re move the keeper, the same is given a quarter turn as indicated iniFigs. 7 and 8 to dispose the nodular extensions II at right angles to the interstice of the jaws, the extensions l8 spreading the jaws in opposition to the spring characteristic of the keeper to release the pin branches I 5.

Modifications of the invention will readily appear and'it is my intention that the same be limited only as by thescope of the hereto annexed claims.

What I claim, is: v

1. In combination with a pick-out shield of a character adapted to be suspended from the fatty rump of a fowito overlie the rectal opening, a pin member shaped to a relative U to provide laterally disposed parallel arms and a medial portion connecting the arms, said medial portion having a hinge connection with the upper end of the shield and the laterally disposed arms providing pointed extremities for passing the same vertically through the fatty rump of the fowl, and a keeper adapted to engage over the tips of the rump-penetrating arms to guard the points and prevent retraction of thearms from the rump. p r

2. In combination with a pick-out shield of a character adapted to be suspended from the fatty rump of a fowl to overlie the rectal opening, attachment means therefor comprising relatively parallel pin elements hingedly connected to the shield at one end of the same and having their opposite ends pointed for passing the pin elements upwardly through the fatty rump of the fowl at each side of the terminal point of the fowls back-bone, and means adapted to fit over the protruding points of the pin elements to resist retraction of the pin elements from the rump.

3. A clasp appliance comprising a member of spring wire formed to a relative U shape with the side elements having pointed extremities and providing notches below the points, the material along each edge of the notches projecting outwardly to provide nodular extensions, and a keeper adapted to be introduced over said points for guarding the same, said keeper providing spring-closing companion jaws arranged to engage in the notches for locking the keeper against retraction from the pin member, the nodular extensions acting in response to a twisting of the keeper to spread the jaws in dislodging the keeper.

4. A clasp appliance comprising a pin element pointed at its extremity and providing oppositely disposed notches in the walls of the element below the point, the material along each edge of the notches projecting outwardly to provide nodular extensions, and a keeper of spring metal formed to a general V-shape in edge elevation with its free terminals bent inwardly and upwardly toward the apical po nt of the keeper to provide companion spring-closing jaws arranged to engage in the notches for locking the keeper against dislodgment from the pin element, said nodular extensions acting in response to a twisting of the keeper relative to the pin element to spread the jaws for releasing the jaws from the notches.

5. In a keeperior the point of a pin characterized by the provision of oppositely disposed notches below the point, a guard member formed from a strip of spring metal bent on, its approximate transverse median line to provide companion limbs projecting in diverging relation from the line of the bend, one of the limbs being terminally provided with parallel longitudinal cuts and the material between said cuts together with the terminal portion of the other limb being bent inwardly and upwardly toward the juncture of the limbs I, to produce spring-closing jaws, the laterally-disposed fingers lying at each side of the turned-in portion of the first-named limb being turned inwardly to aninclination less, than that of the jaw elements to overlie the interstice between said jaw'elements and thereby form closures at each end of theiinterstice, said guard member being adapted for introduction over the point of the pin with the spring-closing jaws engaging in the notches to lock the keeper against retraction from the pin.

6. In a keeper for a pin having notches at diametrically opposite sides of its tip portion, a member of spring metal bent to provide companion limbs projecting in diverging relation i'rom the line of the bend, each of said limbs being terminally formed with turnedin portions to provide opposing spring-closing jaws and one of the limbs, at each side of the jaw, providing turned-in finger elements overlying the interstice between the jaws to operate as closures at each end of said interstice, said member being adapted for reception over the tip of the pin to have the spring-closing jaws engage in the notches and thereby lock the pin against retraction.

7. In combination with a pick-out shield adapted to be suspended from the fatty rump of a iowl to overlie the rectal opening, a supporting pin therefor of a relative U-shape hingedly coupled by its medial portion to the shield and having its prongs pointed for passing the same upwardly through the fatty rump of the fowl to lie at opposite sides of the rear terminus of the fowls back-bone.

8. In combination with a pick-out shield adapted to be suspended from the fatty rump of a fowl to overlie the rectal opening, a supporting pin therefor formed to a relative U-shape and hingedly coupled by its cross arm to the shield with its prongs arranged to be passed upwardly through the fatty rump of the fowl to lie at opposite sides of the rear terminus of the fowls back-bone with the tips thereof exposed above the rump, and a keeper operative to engage said protruding tips to operate as a guard for the -tips and to resist dislodgment of the pin from the rump.

9. In combination with a pick-out shield adapted to be suspended from thefatty rump of a fowl to overlie the rectal opening, means hingedly connected with the shield and arranged to be vertically embedded in said rump from the underside thereof for functionally supporting the shield.
