Application filed March 1, 1927. Serial No. 171,829.

This ini'ention relates to calf weaners and the general object of the invention is to provide a weaner which when applied to a calf will absolutely prevent t-he calf from suckling, which is very simple in construction,

Referring to these drawings it will be seenv that the weaner is constructed from a sheet of metal 10, bent so that the upper portion of the sheet is transversely curved to fit over the face of the calf and having two openings 11 and 12 at about the middle of the sheet. rEhe lower end of the sheet is extended upward in acurve from about the point 13, as at 14, so as to provide a slightly curved, outwardly extending flange 15. Rearward of this flange the corners of the sheet are outwardly bent so as to provide obtusely angled, outwardly projecting portions 15EL on each side of the shield 10.

Riveted or otherwise attached to the outer face of the sheet is a downwardly extending bar 16 whose end is angularly bent and eX- tended through the opening 12. Disposed parallel to the bar 16 is the bar 17 which is pivoted upon a rivet 18 at its upper end, the lower end of the bar being angularly bent a-nd extended through the slot 11. These angularly bent ends are designated 16a and' 171L respectively and are designed to be inserted in the nostrils, these angularly bent portions 16a and 17 s beingpreferably bent inward or towards each other and slightly upward, as shown in Figure 3. The interior of the shield 10 on the concavo-convex portion thereof, is lined with leather 19. Just above the slot 11, the leather lining and the shield are perforated for the passage of an adjusting pin 2O which extends through an opening in the bar 17. This permits the lower end of the bar 17 to be adjusted toward or from the lower end of the bar 16 to thus lit the calfs nostrils.

For the purpose of holding the` shield in place, the leather lining 1 5) is extended to form o bands or straps :21 and 22, one of a basale and the Ahaving vThese bands constitute a head stall` therewith.

Passing through the slots Z3A in the shield and 'lining are the looped ends of straps 2li, one of these straps carrying a buckle and the other strap coacting therewith'. These straps also constitute part of the head stall andare designed to pass beneath the headk of the animal and around its throat. In putting this weaner in place, the pin 2O is removed and the bar 17 shifted laterally, the shield is then applied and the bar 17 again shifted perforations coacting laterally in a reverse direction to carry the hook 17a into the calfs nostril, the other hook 16a having been previously inserted. This bar is again fastened in Vplace by the pin 2O and thus it is impossible for the calf to shift the device sidewise and thus get it out of position. Obviously it is impossible for the calf to suck the cow with this device over its face.

The pin 20 is held in place in its engaged f' position in any suitable manner but I have shown for this purpose a springQ which carries this pinand urges it inward. I do not wish to be limited to this means, however.

The shield which constitutes this calf weaner fits over the top of the nose and eX- tends upward to about two inches of the eyes. It does not, however, cover the eyes -nor interfere with sight as the two hooks engaging the nostrils hold the shield in place,

the lower edge of shield being about two inches below the muzzle of the animal. The straps 21 and 22 go around the neck while the straps 24: go under the jaws. This weaner in use keeps the cows nipples out of reach of the mouth of the calf, but does not gouge or' otherwise injure the udder. The hooks hold the weaner down and prevent the calf from turning his head to one side and sucking which they do with other weaners. Weaners constructed in accordance with this invention have been found to be very effective and thoroughly satisfactory.

I claim y 1. A calf weaner comprising a metallic shield having its upper portion transversely curved to fit over the face of a calf and having a head stall whereby it may be held in place, the lower portion of the shield being bent downward and then upward and the lateral corners of .the shield being bent ojit-Y w'ard, and ineans on the shield for' engaging' the ealfls nostrils.

2. A calf weaner comprisinga metallic shield having its upper portion transversely curved to fit over the face of arealf and having a head stall whereby it may be held in place? the lower portion of the shieldrbeing bent downward and then upward and the lateral corners of the shield being bent downward, and means on the shield for engaging the cal'fs nostrils includ-ing a fixed bar attached to the shield and having an inwardly curved hook at its lower end to engage in the nostril, and a bar pivoted upon the shield and having` an inwardly turned hook at its lower end, the shield being, provided with openings through which the hooks extend, the opening for the hook of the pivoted bar heingin the form ofV a slot, anddetaehable means for holdingT the har. at theinner. end ofV said-slot.A

3. A calfweaner ofthecharaoter 4described including4 a, metallic shieldfhaving itsnpper portion transversely curved to tit over the face of the animal and its lower portion eX- tended downward and then outward, the side margins of the shield at its corners being outwardly extended, a lining of leather attached to the inner face of the shield and extended beyondthe, shield to form straps having adjustable engagement-with each other,` theshield being perforated at two adjacent points, a bar attached to the shield and han. ing a. hook extending through one of said perl'orations, a bar attached to the shield and havingV a hook extending through the other perforation and laterally adjustable therein, and straps attached to the upper Corners of the shield and extending thronghthe lining thereof and` adapted,y to.` engage v around*v the calfs neck.

In testimony whereof I hereunto al'lixfmy signature.
