200 EESTEAIIfT OF DOMESTIC ANIMALS. 



cushion to turn will be positively obstructed so that all danger 

 of variation in the position of the animal vsrill be obviated. 



Means will also be provided in connection with one or both 

 of the end frames for attaching halter straps or other head har- 

 ness and great care will be exercised in the formation of the 

 several parts as to distances apart to overcome any tendency to 

 injury of the animal during his retention within the table. 'It 

 will also be understood that the animal may be either led or 

 backed into the table, and after the operation has been per- 

 formed the release of the animal is pursued reversely to the 

 steps just described in securing him. 



One of the most essential features of the present invention 

 is the mechanism for tilting the table to any position and hold- 

 ing it locked after the desired adjustment has been obtained. 

 As before indicated this table, together with the attachments 

 therein, is adjustable either to the right or left and fully through 

 a circular path. It is obvious that under the control of certain 

 actuating mechanisms the table, especially after an animal has 

 been placed and secured therein, would require considerable 

 manual strength to throw or position the animal at the angle 

 desired. Consequently it is imperative from a standpoint of 

 facility of .operation that the necessary concomitants of the 

 mechanism for adjusting or operating a table of this class are 

 that they shall combine great strength, ease of operation, freedom 

 from damage in use, and positiveness in holding the table at any 

 required adjustment. Mechanism having the foregoing re- 

 quirements in the present instance consists of a worm wheel 

 secured to the pintle and held in constant mesh with a worm 

 carried by a shaft having bearings in opposite brackets on the 

 adjacent standard. The shaft is journalled in suitable ball 

 bearings, to reduce the friction in the operation of such shaft. 

 When a horse is reclining upon either of the cushions, the lateral 

 thrust against the threads of the worm will be excessive, and the 

 provision of these ball-bearings reduces the resistance to move- 

 ment of the shaft to a minimum. 



This invention relates to veterinary operating tables wherein 

 a frame or holding means is movably disposed and fulcrumed 

 between uprights or standard devices anchored to a base rest.
