Abstract
Abstract A device for use with a walkaway bracket, adapted to positively grasp breathing apparatus. Slide rails are fastened to a bracket, which bracket is affixed to a rescue package. Locking means are slidably received between the slide rails, and which locking means include a plate slidably received between the slide rails, and housings mounted at the extremities thereof. One of the housings includes an actuating means, the other including a positioning means characterized by a positioning finger. The housings each include openings which receive therethrough arm members which are pivotally mounted to the slide rails. A cam is associated with the actuating means and is active on one of the arm members. This action is translated into sliding movement of the locking device toward that arm member. Simultaneously the arm members are pivoted toward convergence with each other and they positively grasp the tank of the breathing apparatus.

Claim 7
Dependent Claim
33 words
The device of claim 5 includiNg an adjustable thumb wheel mounted on said finger which cooperates with means on said second housing to adjustably position said finger to grasp tanks of various sizes.
Claim 8
Dependent Claim
34 words
The device of claim 1 wherein said locking means includes a plate received between said slide rails and said housings are fixedly suspended above a face of said plate, connected thereto by rapid flanges.
Claim 9
Dependent Claim
130 words
The device of claim 1 wherein said breathing apparatus comprises a generally cylindrical tank, and said arm members are bowed so as to embrace said tank, said actuating means comprises a lever pivotally mounted to said first housing having a cam attached thereto, said cam being active on said first arm member as said lever is pivoted, and said positioning means includes a finger active on said second arm member to pivot said arm member into engagement with said breathing apparatus as said locking means slides toward said first arm member, whereby upon actuating said locking means, said cam pivots said first arm member and said finger pivots said second arm member, said pivoting of said arm members being toward convergence with each other, which arm members embrace said tank.
