SPEAKING-TUBE FOR DlVING-ARMORS.

SPECIFICATION forming part of Letters Patent No. 269,187, dated December 19, 1882.

Application filed June 15, 1882;

To all whom it may concern:

Be it known that we,WILL1AM H. DARLING and JoHN S. BUNDIcK, of New York, in the county of New York and State of New York, haveinvented a certain new and useful Improvement in Speaking-Tubes for Diving-Armors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates to an improvement in attachments for diving-armors, the object of the same being to provide means of communication between the diver and the attendants in the boat or on shore.

A further object of our invention is to provide means for preventing the ingress of water into the armor in case the pipe should break or spring a leak.

A further objectof our invention is to provide means for preventing the compressed air forced into the armor from above from passing out through the speaking-tube, which would prevent sounds made by the attendants in the boat or on shore from reaching the diver; and with these ends in view our invention consists in certain details of construction and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view showing our improvement connected to a divers helmet. Fig. 2 is a vertical sectional view of the valves. Fig. 3 is a vertical sectional view of the mouth-piece.

A represents the helmet or head-piece ot' the armor, having the usual ventilating-pipes connected thereto, and provided in front with the mouth-piece B, which latter is situated inside of the helmet, while the shank thereof passes through the same, and is connected to the horizontal arm a ot'v the valve-box 0. This mouth-piece B is secured to the helmet A in any suitable manner so as to prevent the ingress of any water at the connection, and is provided with the flexible diaphragm D, which latter is secured in the shank thereof in any suitable manner, and adapted to cover .the opening between the mouthpiece and valvebox. This diaphragm can be made of sheepskin, tin, or any suitable flexible material, and is strengthened at its rim or periphery, so as (No model.)

to withstand or check the flow of any water that might accidentally get into the tubing before it reaches the diver. This diaphragm also prevents the compressed air forced into the helmet from above from passing upward through the tube, which would prevent the sounds uttered by the attendants in the boat from reaching the diver.

The arm a. of the valve-box U is hermetically connected to the shank of the mouth-piece B, and bears up against the diaphragm D, and holds it in position. This arm a is provided with acentral opening, which communicates with the interior of the valve-box, which latter is composed of thearms a a and the arms I) b, the said latter crossing the said arms a a at right angles thereto. The arms a a are merely a continuation of the tubing E, while the hollow arms I) b serve as guides and seats for the valves F F. These valves F F are rigidly secured to the valve-stem G, which latter passes up through suitable water-proof packing in the end of the arm I), and is provided with a button against which the diver presses when he desires to communicate with the attendants. The valve and stem are constantly pressed upward toward the arm I) by the spring H, and the position of the valve F on the stem G is such that when the pressure is relieved on the button on the end thereof the spring H forces the valves and stem upward until the valve F cuts off the communication between the arms a and a, and consequently looks or closes the valves. These valves accurately tit in the bore of the valve-box, and if by any accident whatever the speaking-tube should become disconnected or the upper end thereof fall over into the water the valve F would completely check the downward flow of water before it reached the diaphragm D. When the valve-stem G is pressed downward by the diver the valves F and F are forced downward until'the space between them comes opposite the openings in the arms a a, which opens the passage for communication between the diver and attendants. As soon as the pressure on the stem is relieved the valves resume their normal position, and communication is again out oit'.

E is the connecting-tube pipe, which we prefer to make of rubber; but it can be made of metal and answer all necessary purposes.

; csmsv This tube is made up ofsections of any suitable I length, and is hermetically connected at one end to the arm a and is provided at its other end with any suitable mouth-piece or trumpet.

'When it is desired to communicate with the diver, or vice versa, a signal is given in the usual manner, and the diver depresses the valve, when he is enabled by our improvement to converse freely with those above water.

Ear-trumpets can also be used by the diver in connectionwith themouth-piece in thehelmet; but itisnot absolutely necessary, as the diver can turn his head sufficiently to enable him to hear directly from the mouth-piece.

Our improvement is simple in construction, of few parts, can be secured to any divingarmor, is efficient in use, and can be manufactured at a comparatively small cost.

Our improvement can be disconnected from the armor when not desired for use by simply disconnecting the arm a from the mouth-piece B and stopping up the latter with any suitablepl ng.

It is evident that slight changes in the construction and arrangement of the different parts might be resorted to without departing from the spirit of our invention, andhencewe would have it understood that we do not limit ourselves to the exact construction shown and described, but consider ourselves at liberty to make such changes as come within the spirit and scope of our invention;

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the helmetof a diving-armor, ofa mouth-piece within the helmet, a

speaking-tube connected with the mouth-piece and extending above the surface of the water, and a flexible diaphragm placed within the mouth-piece, and a self-closing valve for opening and closing the passage between the diaphragm and the speaking-tube, substantially as set forth.

2. The combination, with the helmet of a diving-armor, a mouth-piece located within the helmet, and a speaking-tube, of a valvebox provided with the hollow arms a a b b, valves F F,valve-ste1n Gr, and spring H, sub stantially as set forth. Y

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
