AppFcation filed July, 6, 1908. Serial No. 1,41,957.

' To all whom it may concern:

Be it known that I, ALVIN T. STATA, a. citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Collapsible straining-Funnels; and I 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 appertains to make and use the same.

My invention has for its object to provide an improved strainer funnel especially adapted for use in filling gasolene tanks of automobile engines, but adapted for general use wherever a straining funnel may be found desirable.

For automobile use it is highly desirable that the funnel, when not in use, be capable of being collapsed so that it will occupy but little space and, hence, this improved funnel is made up of a multiplicity of telescopic conical sections.

Dirt and water in gasolene are very detrimental and when introduced into the explosive chamber of the engine materially interfere with the proper running of the engine. They are liable to plug up the minute oil passages of the vaporizer and by collection upon the electrodes of the sparking device are liable to interfere with the proper ignition.

Automobilists, as is well known, very frequently find it necessary to buy gasolene in places along the line of travel where no particular care is taken to keep the gasolene clean or free from water. To provide an eflicient strainer I employ a concave diaphragm or sheet of chamois, the edge of which is secured to the upper edge of the upper section of the funnel, and the intermediate portion of which is preferably connected to the lower section or neck of the funnel, so that when the funnel is drawn out or extended this chamois diaphragm will be drawn down into the funnel and the funnel thereby instantly put in condition for use.

Chamois, as is well known, will permit light oil, such as gasolene, to freely pass therethrough, but will hold back or restrain the passage therethrough of water and of all foreign materials, such as dirt. It is, therefore, the proper material for use as a strainer for gasolene.

The invention is illustrated in the single view of drawing wherein the numeral 1 indicates the stem of the funnel, and the numerals 2, 8, 4 and 5 indicate the telescopic sections which make up the funnel. The upper end of the stem 1 telescopes into the lower section 2 and is flared'to prevent it from being completely drawn out of the same. The chamois diaphragm or sheet 6 is preferably detachably secured at its upper edge to the upper edge of the body section 5, by a clamping ring 7. The central portion of this chamois diaphragm 6 is gathered around a body, such as a buck-shot 8, and a light wire or cord 9 is tied around the same at its intermediate portion and connected at its ends to the upper end of the stem 1, as

shown at 10.

It is evident that when the sections of the funnel described are pushed together, or, in other words, when the funnel is collapsed, it will occupy but very little space and hence may be easily carried in an ordinary tool boX. When, however, the sections of the funnel are drawn out or extended as shown in the drawing, the diaphragm 6 will be drawn into the same and the funnel will be instantly put in condition for use.

It is important that the connection between the chamois diaphragm and the lower section of the funnel be made without perforating the said diaphragm. Chamois, if perforated even by the finest stitches, will not hold back water and, hence, a connection including a ball and cord or flexible wire affords a simple and efficient means for connecting the diaphragm to the lower funnel section without decreasing the efiiciency of the said diaphragm as a strainer for the purposes had in view.

To prevent collapsing of the funnel when the sections thereof are drawn out, as shown in the drawing, two or more rods or arms 11 are pivotally connected to lugs 12 on the uppermost funnel section 5 and their free ends are adapted to be engaged with stop lugs 13 on the lower funnel sect-ion 2. In the drawing, one of these rods 11 is shown as engaged with one of the lugs 13, for the purposes above stated, while the other thereof is shown as folded or turned over the top of the upper funnel section 5 to illustrate the manner in which both rods will be folded when the funnel is collapsed.

lVhat I claim is:

1. A collapsible funnel provided with a chamois diaphragm connected atits edge to the edge of the upper portion of said funnel and having its intermediate portion connected to a lower portion of said tunnel, whereby, when the funnel is extended, said a diaphragm will be drawn into the same.

2. A collapsible funnel made up of telescopic sections, in combination with a chamois diaphragm connected at its edge to the upper edge of the upper funnel section, and a flexible connection between the intermediate portion of said diaphragm and the lower section of said funnel, whereby, when the funnel is extended, said diaphragm will be drawn into the same.

3. The combination with a collapsible funnel, of a flexible diaphragm attached to its edge to the upper portion of said funnel, a ball or head applied to the central portion of said diaphragm and around which the said diaphragm is gathered, and a flexible connection secured about the gathered portion of said diaphragm above said ball or head, and attached to the lower portion of the funnel.

In testimony whereof I aitix my signature in presence of two witnesses.
