170 EESTEAINT OF DOMESTIC ANIMALS. 



The New Tork State Veterinary Operating Table is made of 

 metal, except those portions upon which the body of the animal 

 rests. The frame work is built of steel channels and I-beams 

 securely connected, making a rigid support for the oak and 

 plate steel platform. Th^ wooden portion of the platform is 

 made in three pieces; a main section and two smaller inter- 

 changeable square pieces. These may be entirely removed or 

 placed in suitable positions for the head and tail ; that intended 

 ,for the head being slightly inclined. 



Two heavy cast iron supports are provided, having their 

 upper ends connected by hinged joints to the table, and upon 

 these the table rocks from vertical to horizontal positions. The 

 movement of the table from one plane to another is accomplished 

 by a hydraulic cylinder, bolted to the foundation through a 

 rocking joint, having its piston rod attached to the under side of 

 the table frame ; by admitting water to eitjier end of the cylinder 

 the piston rod can be moved in or out and the table rocked to 

 the desired position. When the table is horizontal it rests on two 

 metal posts of suitable height, which, together with the two main 

 standards, give four points of support whereby all tendency to 

 vibration is eliminated. 



Figure 195 shows the table in an upright position ready for 

 use. The animal stands close beside it. The halter strap is 

 passed through a convenient aperature in the detachable head 

 piece of the table and the head pulled against the surface, after 

 which the strap is tied to cleats provided for the purpose. When 

 this is done the girth-straps and foot nooses are tightened, the 

 latter being accomplished by suitable ratchet windlasses on 

 the under side of the platform. If required, the tail may be 

 lashed to the detachable tail piece. 



When the animal is thoroughly secured, the table may be 

 tilted over by the hydraulic cylinder until it lies horizontally, 

 or, if desired, to any intermediate angle, where it may be sus- 

 tained indefinitely. 



The cylinder is double acting, and so controlled by a valve 

 as to be positively located in every position. Its action is 

 smooth and free from all undesirable vibration. A small triplex 

 pump driven by an electric motor provides the water supply. A
