Animal holding crate
BACKGROUND OF THE INVENTION 
     Animal holding crates are used to restrain animals such as cattle or the like therein while the animals are being examined, treated, vaccinated, etc. Animal holding crates are well known in the art and normally comprise a pair of end frames which are spaced from one another and which are joined by side frame members. A gate is normally provided at each of the end frames to maintain the animal in the crate at times and for permitting the animal to pass therethrough when needed. Although the animal holding crates of the prior art have been generally satisfactory, it has been found that the gates, when in their open position, do not permit the animal to freely pass therethrough. It has also been found that the gates of the prior art devices are not easily operated. 
     It is therefore a principle object of the invention to provide an improved animal holding crate. 
     A further object of the invention is to provide an animal holding crate including a gate means at each of the opposite ends thereof which are operated by means of a power cylinder. 
     Still another object of the invention is to provide an animal holding crate wherein the animal restraining members at the opposite ends of the crate, when opened, permit the animal to freely pass therethrough. 
     These and other objects will be apparent to those skilled in the art. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     FIG. 1 is a perspective view of the animal holding crate of this invention; 
     FIG. 2 is an end view of the animal holding crate of this invention with the restraining members at one end thereof in a closed position; and 
     FIG. 3 is a view similar to FIG. 2 except that the restraining members have been moved to their open position. 
    
    
     SUMMARY OF THE INVENTION 
     An animal holding crate is described including a pair of spaced-apart end frames each of which have a pair of vertically disposed restraining members or gate members movably mounted thereon which may be moved from closed to open positions. The restraining members are moved from their open to closed positions by means of a power cylinder operatively connected thereto through a linkage. When the restraining members at one end of the crate are in their closed position, the restraining members are positioned closely adjacent one another to prevent the passage of an animal therebetween. When the restraining members at one end of the crate are positioned in their open position, an animal may freely pass therebetween. 
     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The animal holding crate of this invention is referred to generally by the reference numeral 10 and includes end frame means 12 positioned at one end of the crate and end frame means 14 positioned at the opposite end of the orate. The end frames 12 and 14 are joined by means of suitable side bracing to maintain the animal in the orate and to provide suitable strength to the crate. The specific side bracing is not a part of the invention and has been omitted in the drawings for purposes of clarity. 
     End frame 12 includes a top frame member 16, bottom frame member 18, and opposite side frame members 20 and 22. A vertically disposed restraining member 24 is movably mounted on end frame 12 and has a pair of -shaped brackets 26 and 28 provided on its upper and lower ends respectively which slidably embrace top frame member 16 and bottom frame member 18 respectively. The numeral 30 refers to a second restraining member movably mounted on end frame 12 and which has C-shaped brackets 32 and 34 at its upper and lower ends respectively which movably embrace top frame member 16 and bottom frame member 18 respectively. 
     Links 36 and 38 are pivotally connected to restraining member 24 at 40 and 42 respectively and are pivotally connected to links 44 and 46 respectively at 48 and 50 respectively. 
     Link 44 is pivotally connected to bracket 52 at 54. Link 46 is pivotally connected to bracket 56 at 58 as seen in FIG. 1. The outer ends of links 44 and 46 are pivotally connected together by means of link 60 extending therebetween. The upper end of link 60 is pivotally connected to link 62 and is operatively pivotally connected to ear 64. Ear 64 is secured to pipe 66 having ear 68 secured thereto and extending upwardly therefrom as seen in FIG. 1. Power cylinder 70 is operatively pivotally connected to ear 68 so that extension and retraction of the cylinder rod 72 will cause restraining member 24 to slidably move between its open and closed positions. Ear 74 is also secured to pipe 66 and has link 76 pivotally connected thereto. The outer end of link 76 is pivotally connected to the link 60&#39; which is operatively connected to the restraining member 30 in the fashion identical to that described for restraining member 24 whereby retraction and extension of the cylinder rod 72 will cause the restraining member 3 to be moved between its open and closed positions. 
     It can be seen that when the restraining members 24 and 30 are in the position of FIG. 2, the restraining members 24 and 30 will prevent the passage of an animal therebetween. When the restraining members 24 and 30 are in the open position of FIG. 3, the distance between the restraining members 24 and 30 is substantially equal to the distance between the frame members 20 and 22 so that an animal may pass freely therebetween. 
     In the preferred embodiment, the end frame 14 of the crate 10 has a pair of restraining members 24&#39; and 30&#39; movably mounted thereon which are moved to their open position when the restraining members 24 and 30 are moved to their closed position and which are moved to their closed position when the restraining members 24 and 30 are moved to their open position. Thus, in the position of FIG. 1, an animal may enter the crate between the restraining members 24&#39; and 30&#39; with the restraining members 24 and 30 preventing the animal from exiting the crate. When the animal has entered the crate, restraining members 24&#39; and 30&#39; will be closed behind the animal to prevent the animal from leaving the crate. When the animal has been treated or examined, restraining members 24 and 30 are opened to permit the animal to leave the crate. As soon as the animal has exited the crate, the restraining members 24 and 30 would again be closed. At that time, restraining members 24&#39; and 30&#39; would be opened to permit the next animal to enter the crate. 
     Thus it can be seen that a novel animal holding crate has been provided which is not only convenient to use but which includes restraining members which do not create an obstruction to the passage of an animal therebetween when moved to their open position. Thus it can be seen that the animal holding crate of this invention accomplishes at least all of its stated objectives.
