LIQUm-FEEDING DEVICE.

Specification of Letters Patent.

Patented Mar. 27, far a.

Application filed April 16, 1915. Serial 1W0. 21,700.

To all whom it may concern:

Be it known that I, LOUIS 1E. BALTZLEY, a citizen of the United States, residing at VVeehaWken, in the county of Hudson and State of New Jersey,

Feeding Devices, of which the following is a specification.

This invention relates to liquid feeding devices and comprises a container having fluid delivering means at one end, a valve for regulating the size of the opening in said delivering means, a threaded stem carrying the valve and leading to the upper portion of the container, a spring supportwhich the stem is threaded, and a handle for operating the same to lower and raise the valve.

This feeding device is particularly useful as an oil dropper to be used for olive oil and the like in preparing salad dressings. It is provided with tubular delivering means adapted to fit a hole in the top of a culinary beater and to be maintained in tubular delivering means whereby the operator may have both hands free, one to operate the handle of the valve stem and the other to operate the handle of the beater. In preparing mayonnaise dressing the best results are obtained when, particularly at the beginning of the operation, the oil is fed to the substance that is to be mixed in very small amounts. The oil should be fed drop by drop and should be thoroughly mixed with the other substance in the beater.

fter thorough mixing of these small quantities of oil and other substance the oil may vention serves admirably to feed the oil as required.

The invention has for its objects the provision of an oil feeding device capable of h have invented certain new and useful Improvements in Liquldplace by such deviceof a size adapted to fit a hole in the top of a culinary beater. The upper edge of the container is, provided with a flange or car and a removable resilient stem-supportlng member. This member preferably has openlngs near opposite ends, the outer edges of the openings serving to engage the body of the container under the ears.

A somewhat larger opening may be made by pressing the handle downwardly and the valve may be entirely removed by pressing the hanpoint substantially such member are dle downwardly to a further extent and re-. moving the handle, its supporting member to ether with the valve.

11 the accompanying drawings Figure 1 is a side elevation of the liquid feeding device. Fig. 2 is a vertical section showing the rodand valve in elevation. Fig. 3 is a top plan view. Fig. 4 is a perspective of the spring supporting member. Fig. 5 is a section of Fig. 4 along line 5-5, and Fig. 6 is a modification of the lower end of the device.

Referring to the drawings, reference numeral 1 indicates the funnel shaped container' having the flange 2 and theears 3 projecting therefrom. The top of the container is normally open- At the bottom it is provided with the fluid delivering throat 4. This may be brass or steel riveted to the body as is shown at 5. If desired however the throat may be a continuation of the body of the container as is shown in Fig. 6. The body ofthe container is preferably made of aluminum or other light metal. This throat should advantageously be made of a hard metal, as soft metal would soon be bent out of shape.

In itsarch the Valve 6 normally seats in the end of the threat 4. It is a cone valve which is ar ranged to gradually enlarge the cross sectional flow area of the throat when the valve is pressed downwardly. The valve is supported in place by a stem or red 7 screw threaded at this upper end 8 and pasing through the resilient supporting member 9. This member is made of light spring arch shaped metal. It is provided at either extremity with an opening 10 having edges 11. edges are about the same distance apart as the width or diameter of the container at this upper portion. Downward pressure upolithe middle of this arched spring member will of course spread the edges 11 apart. To place the spring member in position the edges 11 are spread apart by downward presure upon the middle of the spring member and the holes 11, which are larger than the ears 3 of the container are placed over such ears. When released from pressure the inherent resiliency of this member causes it to assume its arched form and the edges 11 are therefore brought into contact with the body of the container under the ars. In order to provide for adjustment of the screw rod in this spring member I split it as is shown at 12. One edge 13 is elevated slightly above the edge 14 a distance corresponding to one thread on the rod. The rod is provided with a rigidly fastened knurled thumb nut or handle 15. The operation is obvious from the foregoing.

What I claim is:

A liquid delivering device comprising a container having at its upper end means for holding a rod supporting member, liquid delivering means said delivering means, -a threaded rod attached to said valve, a movable arch-shaped resilient rod-supporting member bridging the top of the container and engaging the said holding means at the upper end and having a threaded opening through which the rod extends, and a handle on said rod.

In testimony whereof, I aflix my signature.
