CATTLE STANDING HEAT ns'rscwoa Filed Nov 28, 1962 INVENTOR.
HERBERT J. LARSON AT TORN EYS United States Patent Office 3,158,133 Patented Nov. 24, 1964 3,158,133 CATTLE STANDTNG HEAT DETECTOR Herbert J. Larson, 124 Vine St, Fergus Falls, Minn. Filed Nov. 28, 1962, Ser. No. 240,658 13 Claims. (Cl. 1191) The herein disclosed invention relates to an apparatus whereby cattle running at large in big herds, in pastures, can be identified when in heat and easily removed from the herd for breeding as by artificial insemination. Cows are classified as in standing heat when said cow submits to being mounted by another cow, this'condition occurring in the early stage of a heat period. Dairy cattle, which are closely confined and controlled, are largely bred by artificial insemination. Cattle running at large in pastures, such as beef cattle, are not bred artificially because of the almost impossibility of herding a cow out of a herd without some identifying mark. Cows all look the same and it is impossible to keep a mans eye on one cow, and know she is the right cow once she has milled with the herd.
Another object of the invention resides in providing a detector which when once actuated may be reset for repeated use to show whether cow repeats heat or is bred.
A still further object of the invention resides in constructing the detector with a flexible container containing a colored liquid and positioned on the back of the cow to be bred in a position for engagement with the mounting cow.
An object of the invention resides in a transparent receptacle communicating with the container, disposed ahead of the same and adapted to receive the discharge from the container when pressure is applied to the same.
Another object or" the invention resides in providing a connector between the container and receptatcle and havng a passageway therethrough communicating with the interiors of said container and receptacle.
A still further object of the invention resides in providing a check valve across said passageway permitting flow from said container to said receptacle and restraining flow in the reverse direction.
An object of the invention resides in providing the container and receptacle with facing threaded necks and the connector with threaded sockets to receive said necks, the diameters of said necks at said threads being different to prevent interchange of connections between said necks and sockets.
Another object of the invention resides in providing said n cks with bores, one bore being of greater diameter than the other, and in constructing the check valve tubular in form and of a diameter to be received into the bore of greater diameter, said check valve being of a diameter greater than the bore of lesser diameter.
Other objects of the invention reside in the novel construction and arrangement of parts and in the details of construction hereinafter illustrated and/or described.
In the drawings:
FIG. 1 is a perspective view of a portion or" a cow illustrating the application of the invention thereto.
FIG. 2 is a perspective view of the detector before application to the cow.
FIG. 3 is a longitudinal sectional view taken on line 33 of FIG. 2 and drawn to a greater scale.
FIG. 4 is a cross sectional view taken on line 44 of FIG. 2.
FIG. 5 is a perspective view of the valve member of the invention detached from the adjoining structure.
FIG. 6 is a perspective view of one of the fasteners of the invention.
FIG. 7 is a perspective view of a modified form of fastener.
For the purpose of illustrating the application of the invention, a portion of a cow in has been shown in the drawings which illustrates the back 11 of the cow and the backbone 12 running along the same. In addition, the hip bones of the trunk of the cow have been shown which are indicated by the reference numeral 13.
The invention comprises a base or supporting structure 26 on which is mounted a flexible container 30 containing a colored liquid 31 and a transparent receptacle 41) connected together by means of a connector 50. Disposed within the connector St is a check valve 60 by means of which the liquid contained in the container 30 may flow from container 39 and into receptacle 40 but not in the opposite direction. These parts will now be described in detail.
The base 2% is constructed from a sheet of flexible material which may be a sheet of fabric impregnated with a suitable plastic to render the same capable of conforming to surface on which the same is applied. This base may also be constructed of a lastic material in sheet form. The base 2% is provided with spaced holes 21 and 22 arranged at intervals along the same. Fasteners 23, 24 and 25 are employed one at each pair of holes and which are identical in construction. Only fastener 24 will be described. This fastener consists of a bar 2-6 having legs 27 and 23 extending outwardly therefrom and projecting through the holes 21 and 22, the bar 26 underlying the back of the base 26. The leg 27 terminates in an eye 127 while the leg 28 terminates in a hook 128. Operating in conjunction with the legs 27 and 23 is a continuous rubber band 29, looped through the eye 127 and adapted to be hooked on the hook 128.
The container 3% is tubular in form having a body 32 formed with a base 33 at one end and a neck 34 at its other end. The neck 34 is formed with external threads 35 and has a bore 36 extending through it and communicating with the interior of the container which is indicated by the reference numeral 37. Container 36 is constructed of an opaque flexible plastic material such as polyethylene and is adapted upon lateral pressure being applied to the same to discharge the contents of said container through the bore 36.
The receptacle 40 is similar in construction to the container 30 and comprises a body 42. provided with a base 43 at one end and a neck 44 at its other end. Neck 44 is formed with external threads 45 and has a bore 46 extending through it and communicating with the interior 47 of said receptacle. Receptacle 4i? is constructed from a clear plastic material such as polyethylene and which is not easily broken or caused to leak upon pressure being exerted on the same, such as pressure produced by the mounting of one cow on the other. I
The container 3i) and receptacle 4d are connected together by means of connector 50 which has two internally threaded sockets 5t and 52 and into which the threaded necks 34 and 44 of the container 30 and receptacle as may be screwed. The diameter of the neck 4 at the locality of the threads 45 is greater than the diameter of the neck 34 at the locality of the threads 35 so that the respective necks can only be screwed into the particular sockets with which they are intended to operate. Between these sockets connector Stl has an annular partition 53 extending inwardly from said sockets and formed with a central passageway 54 therethrough. This passageway directly communicates with the bore 36 of container 30. The passageway 54 communicates with the interior 47 of the receptacle 40 through the check valve 6% in a manner to be presently explained.
The check valve comprises a tubular body 61 constructed of rubber or some other similar flexible material and which fits freely into the bore 46 of receptacle 40. This bore is of a diameter greater than the diameter of the bore 36 of container fall so that it cannot be. inserted into the same. The body 61 is constructed with a domeshaped end 62 which has a transverse slit 63 in the same. A- flange dd encircles said body and when the valve is inserted. into the bore 36 becomes seated. against the end 48 of the neck. 44 of receptacle 49. This. flange is further seated against the part tion 53 of connector 50 and when the parts are screwed together flow is-possible only from the container 30 and into the receptacle 40. through the slit 63 in the valve as.
The manner of using the invention is as follows: The valve 60 is firstinserted into the bore 4c of receptacle 49 with the flange 64 resting on the end 43 of neck 44. Connector St is then screwed onsaid neck clamping said flange between the partition 53 and said end. Container 39 is next filled with the colored liquid and connector 5i with recetpacle 49 attached screwed on the neck 34 of container 36*. A gasket 54 between the partition 53 and the end 38 of the neck 34- ofsaid container prevents leakage out of the device. The assembly is now placedon the base 29. between the legs 27 and 28 of each of the fasteners 23, 24 and 25. The rubber bands 29 which have been attached to the eyes 127 are now brought over the container 39, connector 50 and receptacle 4G, and hooked over the hooks 123. This holds the device attached to base 26. On the base 26 are marks 19" which indicate where the device is to be placed on the cows back. There are three of said marks indicating the position for different sizes of cows. Base 20 is next coated with a suitable adhesive and the same attached to the cows back 11 straddling the backbone 12 and at the proper position with respect to the hip bones l3as designated by the marks 19 onthe base 20 and with receptacle 40 foremost. Any substantial downward pressure exerted on the container 3%) as by a cow mounting the cow in heat will. partially collapse the container 30 and force a portion of the liquid therein through the valve 60 and into the interior 47 of receptacle 46. This will readily be apparent through the transparent body 42 of the receptacle' 44L Valve 60 prevents the liquid in receptacle 40 from being drawn back into the container 30.
The advantages of the invention are manifest. The device is extremely simple in construction and easy to operate. The device may be used over and over again by pouring out the liquid discharged into receptacle 40 back into container 30 and washing out said receptacle. The device is positive in action and the actuation of the device readily ascertainable.
The fastener 2'4 shown in FIG. 6 is constructed from sheet metal. An alternate construction shown in FIG. 7 may be constructed of wire. This fastener is indicated by the reference numeral 7t?- and is formed from a length of wire 71. One end 72 of this length of wire is bent back upon itself to form a bend '73 and two parallel reaches 74 and 75. The reach '75 at its end opposite the bend 73 is turned upwardly and bent back upon itself to form an eye-76. The other end 77 of the length of' wire is bent to form a hook 7 h at its free end and a reach 79 parallel with and'extending along the reach 74. Reach 79 issues from the lower end of theeye 76. Reaches 74, 75 and 79 all lie in a common plane and take the place of the bar 26 of the fastener 24'. The use of the fastener 70 is the same as theme of the fastener 24.
While it has been found that a suitable adhesive may be applied to the base 2%) at. the time of application of the device to the cow, a previously applied adhesive may also be employed, protected by a covering of Holland cloth or the like and adapted to be removed before application of the device to the cows back.
