ALBERT ULLMANN, OF MACON, GEORGIA, ASSIGNOR OF ONE-HALF TO JULIUS J. WAXELBAUM, OF MACON, GEORGIA.

FLUID-CONTROLLING DEVICE.

Specification of Letters Patent.

Patented July 21, 1908.

Application filed October 30, 1907. Serial No. 399,878.

To all whom it may concern:

Be it known that I, ALBERT ULLMANN, a citizen of the United States, residing at Macon, in the county of Bibb and State of Georgia, have invented new and useful Improvements in Fluid-Controlling Devices, of

' a combined valve and carrier formed of a single piece of material and with the carrier so set up as to reduce the retarding of the flow of gas through the valve casing to a minimum.

Further objects of the invention are to provide a combined valve and carrier which shall be extremely simple in its construction, strong, durable, eflicient in its use and inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of the invention but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings, wherein like characters denote corresponding parts throughout the several views-Figure 1 is a vertical sectional view of a valve casing, showing the arrangement therein of a valve in accordance with this invention, the valve being in open position; Fig. 2 is a like view with the valve in closed position, and, Fig. 3 is a perspective view of a combined valve and carrier in accordance with this invention. perspective view of a modified form.

As illustrated, the carrier is shown cylindrical in contour so as to conform to the sha e of the valve chamber, but it is to be un erstood that the carrier can be of a contour corresponding to that of the chamber in which the carrier operates.

Referring to the drawings in detail, 1 denotes the valve casing formed with a chamber 2, which terminates in a passage '3 co1nmunicating with a tapering outlet 4, the wall of which constitutes a seat for a needle valve. The lower end of the chamber 2 has the wall thereof screw-threaded, as at 5, with which is adapted to engage a screw-threaded supply pipe (not shown). The valve casing 1 is furthermore provided with a laterallyextending annular flange 6 formed with interior screw threads adapted to be engaged by the exterior threads of the sleeve 7.

Extending through the sleeve 7 is a shaft 8 carrying on its inner end a disk 9 with which is adapted to abut the inner end of the sleeve '7 when the latter is screwed home. The disk 9 carries an inwardly-extending eccentrically-mounted pin 10. The outer end of the shaft 8 is provided with a thumb-piece 11. The sleeve 7 constitutes a means for connecting the shaft 8 to the valve casing, but the inner diameter of the sleeve 7 is such as to allow the shaft 8 to rotate or oscillate when occasion so requires. The foregoing parts are of known construction and no claim is made thereto.

Within the valve chamber 2 is mounted a combined fluid controlling device and carrier in accordance with this invention, and which is formed of a single piece of wire bent to provide a plurality of loops or coils 12, 13 and. 14, the loops 13 and 14 being connected together by a vertically-extending portion 15, while the loops 12 and 13 are connected together by the curvilinear portion 16. The loops 12, 13 and 14, the vertically-extending portion 15 and curvilinear portion 16 constitute the carrier. The wire above the loop 14 is bent inwardly so as to extend to a point approximately centrally of the loop 14, and then the Wire is bent upwardly as at 17, forming a vertically-extending portion which constitutes a valve stem and is pointed as at 18, to form a needle valve.

The loops 12, 13 are arranged in close proximity to each other and the space 19 be tween the same receives the pin 10 so that when the shaft 8 is oscillated'or rotated the pin 10 will engage the loop 13 to elevate the needle valve or engage the loop 12 to lower the said valve.

In Fig. 4 a modified construction of valveis shown and which consists of forming the device of a single piece of wire bent to provide a plurality of loops 20, 21 and 22, the loops being arranged in close proximity to each other and constituting a carrier for the valve. That portion of the Wire which forms the separated by a vertically-extending part ofthe wire as is shown in Fig. 3 and that the point10 is adapted to engage with an eye 23 for shifting the valve in lieu of extending between a pair of loops.

By setting up a controlling device in a manner as hereinbe'fore set forth it does not necessitate any machine work in manufacturing the controlling device such as drilling, cutting, sawing, punching or soldering, etc. The combined valve and carrier is formed without any oi the foregoing requirements and under such circumstances can be con venient'ly manufactured at a minimum eX- ense.

Although the carrier is shown cylindrical, yet the wire which forms the body portion can be bent to a contour similar to that of the valve chamber.

The setting up of the carrier in a manner as stated reduces the retarding of the flow of gas to a minimum owing to the fact that the vertically-extending portion 15 is arranged in close proximity to the wall of the valve chamber and. that gas can pass up and through the loops 12, 13 and 14 without being interrupted.

In lieu of forming the upper end of the vertically-extending portion 17 as a needle valve it is evident that to the upper end of said vertically-extending portion a disk can be secured, or any other form of valvular member can be attached.

It will furthermore be evident that the construction of combined valve and carrier in a manner as stated not only has the advantage of cheapness of manufacture, but reduces the cost of assembling to a minimum.

What I claim is 1. A fluid-controlling device formed of a single piece of wire bent to constitute a carrier provided with an opening to receive an actuating means for the device, said carrier terminating at its top in a vertically-extending valve stem.

2. A fluid controlling device formed of a single piece of wire bent into a plurality of loops to form a carrier, a pair of said loops arranged in close proximity to each other and another of said loops connected to the upper one of said pair of loops by a vertically-extending portion, said wire. further bent to form a vertically-extending valve stem positioned approximately centrally of the upper loop of the guide. 7

3. A fluid-controlling device formed of a single piece of wire bent to constitute a plurality of loops to form a carrier and provided with an opening to receive an actuating means for the device, the upper of saidloops terminating at its top in a vertically-extending portion constituting a valve stem having its free end pointed to constitute a needle valve.

V In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ALBERT ULLMANN.
