FLUID-CUT-OFF DEVICE.

Specification of Letters Patent.

Application filed September 5, 1911.

Patented Apr. 30, 1912.

Serial No. 647,548.

To all whom it may concern:

Be it known that I, HUBERT Now, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Fluid-Cut-Off Devices, of which the following is a specification.

The invention relates to cut-offs, and more particularly to the class of devices for turning off the flow of fluid in buildings, especially gas.

The primary object of the invention is the provision of a device of this nature in which the flow of gas from a street surface main may be quickly shut-01f, leaving absolutely no gas in the house pipes, thereby eliminating all danger of explosion and damage in time of fire.

Another object of the invention is the provision of a device in which the occupant or tenant of a house from the first floor thereof may shut-off the gas supply from the street main surface, without the necessity of going into the cellar or basement, thus enabling convenient and quick control of the cut-off valve.

A further object of the invention is the provision of a cut-01f device of this character which is simple in construction, readily and easily operated, and thoroughly reliable and efficient in its purpose, and inexpensive in installation.

With these and other objects in view, the invention consists in the construction,- combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a perspective view partly in section through the cellar and first floor of a building, and portion of a side wall, showing the cut-off device. Fig. 2 is a vertical sectional View. Fig. 3 is a fragmentary top plan view of the cut-ofi valve. Fig. 4 is a fragmentary detail plan view of the hand operating wheel.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings by numerals, 5 designates a portion of a vertical front wall of a building, 6 the flooring between the cellar 7 and the first floor 8 thereof. Arranged below the sidewalk 9 is a casing 10, the same being arranged just outside of the olf or turn valve cook 13, which is of the usual type, and upon its stem 14: is fixed a pulley or peripherally grooved turning wheel 15, about which is trained a chain 16, the same being also trained over guide pulleys 17 fixed upon the inner face of the front wall 5, above the meter 12, and upon the pulling upon one end of the said chain 16, the pulley 15 may be rotated for shutting off the cook 13, thereby stopping the flow of gas through the inlet pipe 11 to the house pipes (not shown).

Arranged above the flooring 6 upon a suitable support or upright 18 is a rotatable Wheel 19, the same being provided with suitable peripheral grooves receiving the end portions of the chain 16 which are reversely trained over the said wheel 19, one end of the chain 16 being connected to a hook terminal 20 of a coiled retractile spring 21, the opposite hook terminal 22 of which being connected to an eye 23 fixed in the inner face of the front wall 5 of the building, the spring 21 being disposed below the flooring 6 and within the cellar. The opposite end of the chain 16 is provided with a pull ring 2 1, so that when it is desired to shut-01f the flow of gas from the street main surface through the inlet pipe 11 to the meter 12, it is only necessary to pull upon the ring 24, so that the chain 16 will cause the wheel 19 to turn, the said chain being tensioned by the spring 21, and simultaneously with the turning of the wheel 19, the pulley 15 will turn, thereby closing the valve cook 13 in the pipe 11, thus shutting off the supply of gas to the house pipes.

Fixed to the support or upright 18 is a spring arm 25, the free end of which is provided with a stop lug 26 which is adapted to engage withany one of the spokes of the wheel 19 for holding the same against rotation, but by reason of the yieldability of the spring arm 25, the lug 26 can be-moved out of the path of the spokes of the wheel 19, so that it may be free for rotation, when pull is exerted upon the chain 16 for the closing of the gas cook in the inlet pipe, for a purpose hereinbefore described.

What is claimed is:

1. The combination with a gas inlet pipe having a normally open cut-ofi' valve therein, of an operating device comprising a manually operated turning Wheel having peripheral grooves, a pulley Wheel connected with the valve, a chain trained over the pulley Wheel and having its ends reversely trained over the turning Wheel, a tension spring connected With one end of the chain and also With a stationary support, and a pull ring connected with the other end of the chain.

2. The combination with a gas inlet pipe adapted to lead from a street surface main into the cellar of a building, of a valve located in the pipe and having a stem, a pulley fiXed to the stem, a support rising from a floor above the cellar of such building, a turning Wheel rotatably connected With said support, guide pulleys fixed to one Wall of the cellar above the inlet pipe, a pull chain trained over the guide pulleys and also about the first-named pulley, the ends of the chain being reversely trained over the turning Wheel, a coiled retractile spring fixed at one end to a Wall of such building and connected to one end of the chain, a pull ring fixed to the other end of the chain, and means engaging the turning Wheel to hold the same normally locked.

In testimony whereof I affix my signature in presence of two Witnesses.

HUBERT NOLD.
