No. 779,946. PATENTED JAN. 1o, 1905. o LINK ROTARY PUNNEL 009K.

APPLICATION FILED OUT l 1903 UNITED STATES Patented January 10, 1905.



SPECIFICATION forming part of Letters Patent No. 779,946, dated January 10, 1905.

Application led October 1,1903. SerialvNo. 175,278.

To all whom, it Uta/y concern.'

Be it known that I, OLIVER LINK, a citizen of the United States, residing at St. Charles, Missouri, have in vented acertain new and useful Improvement in Rotary Funnel-Cocks,of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawing, forming part of this specilication.

This invention relates to a new and useful improvement in funnel-cocks for car-heating apparatus, the object being to construct a device of the character described which is simple and cheap in construction and which will protect the system from the entrance of dirt and dust at this point, said funnel-cock being' combined with an ordinary cock having a vent which is opened coincidently with the opening of the ordinary cock to admit water into'the system.

I/Vith these objects in View the invention consists in the construction, arrangement, and combination of the several parts, all as will be hereinafter described and afterward pointed out in the claim.

The cock shown in the drawing is designed to be attached in position to a tank usually arranged on top of the coach, and the casing or shell is provided with a threaded nipple l to effect this attachment.

2 is a rotatable plug-cock'having a passag'e 8, which is designed to open and close communication from the funnel-cock to the tank, said plug-cock also having a passage 4, which is designed to register with passages 5 and 6, the former opening to the exterior and the latter to the interior of the tank, whereby when the plug-cock opens communication between the funnel-cock and the interior of the tank the vent-openings 4:, 5, and 6 will be in registration for well-understood purposes.

7 is a handle on the plug-cock for operating the same. r

8 is a hollow extension or boss having atapered outer face, through the upper face of which opens a port 9 and through whose lower face opens a port 9a. On this tapered projection is mounted the hub IO of a funnel 1l, the same being held in position by a nut secured on the threaded extension of said hollow projection. When the funnel is in an upright position, as shown in full lines, and the 'plug-cock is rotated to open communication with the interior of the tank and coincidently open the vent-passages, water poured into the funnel will be conducted to the interior of the tank, as will be readily understood.

In practice usually a surplus of water is introduced into the tank, and this is indicated by the water overfiowing the vent-opening. When this stage is reached, the funnel is turned from its upright position to its lower position, so that the surplus water in the tank will escape through the port 9a. When the proper water-level is reached, the plugcock is turned to close communication between the tank and the exterior, both with respect to the water-passage of the vent-opening.

I am aware that minor1 changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing' from the nature and principle of my invention.

Having thus described the invention, what is claimed as new, and desired to be secured r by Letters Patent, is-

In a iiller-cock for water-heaters, the combination with a valve-casing, the outer end of which is provided with a conical wall having a threaded projection at one end, said casing having two longitudinally-arranged ports, one of which is provided for the passage of air and water and the other for the passage of water, the rst-named port being above the other and extending in a straight line longitudinally through the casing, so that all parts of the port are in alinement with each other, a plug arranged in the casing and intersecting the iirst-named port and having an opening alining with the opening in the yplug below the Elrst-named opening therein, said second-named opening alining with the lower Water-port, the casing being' provided with a transverse channel at the end of thelower signature,inthepresenceoftwo Witnesses,this plort, a conica leeve fitting over one end of 23d day of September, 1903. t e casing an mving an opening for registration with oppositely-disposed discharge- OLIVER LINK' 5 ports therein, and a funnel Carried by the Witnesses:

sleeve; substantially as described. THEODORE C. BONRE,

In testimony whereof I hereunto ax my l LEONARD C. SGHAFER.
