T0 (MZ 1071/0771/ it mfcty/ concern: v

Be it known that I, THOMAS K. BAKER, a citizen of the United States of America, and a resident of Minneapolis,vin the county of Hennepin and State ot' Minnesota, have invented certain new and 'useful Improvements in Coffee-Makers, ot' which the following is a specification.y

My invention relates to coffee-makers, and more particularly is an improvement upon the codec-maker described in my application for Letters Patent, Serial No. 81,810, tiled November l1, 1901.

The object of my invention is the production of a simple and efficient coffee-makerV (adjustable to coffee-pots of varying styles) in which the strainerniay be easily and quickly attached, so as to produce a tight joint be.- tween the wall ofthe open end ot' the vessel and the strainer.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of my im proved cotfee-maker,shown partly in section. Fig. 2 is a perspective view of the holder for the strainer. Fig. 3 is a perf spective View of the holder with the strainer attached, part of said strainer being broken away to show the split ring by which it is adjusted to the holder. Fig. 4 is a sectional view of the valve in the bottom of the coffeemaker.

In the drawings, letA represent the coiee-- maker, which is formed with the open tapering end B and provided ,with the circular flange 2, Which surrounds the opening or mouth of the vessel. The handle 3, threaded at 4 in the side of the vessel, is shown partly broken away. This handle may be detached by unscrewing for convenience in shipment and use of the codec-maker. The strainer O, made of cloth or other suitable material, as shown, is circular in horizontal cross-section and tapers slightly from itsopen to its closed ends. The open end of the strainer is adapted to t inside the flange 2 in the open end ot' the vessel and is provided with the split spring ringer collar 5 for attaching the strainer to the holder D, as shown in Fig. 3. This holder is a skeleton frame ot suitable shape to fit snugly inside and hold the strainer open. The holder is provided with the collar 6, to which the handle 7 is attached. The

4'of the'tlange, as shown in Fig. 1.

wire loop S atvthe base of the holder is attached to the collar by the side arms 9, which are joined at 10 and 1l, respectively, to the loop and collar.

The valve E (shown in the drawings) is automatic in action and consists of the stein11n, sliding through the opening l2 in the inner cylindrical projection 13 on the bottom 14 of the coffee-maker. The valve-head 15 is attached to the upper end of the stem 11 and is seated on the projection 13. The stem is provided with the passage-way 16, (see Fig. 3,) which is adaptedto receive air into the vessel when inverted. The lower end of the stem is provided with the washer 17, Which is att-ached by screws 18 and adapted to abut against the .shoulder lt). The head and washer limit the movement of the stem. The Washer is provided with the opening20, which registers with the air passage-way 16. The stem slides when the vessel is tilted or inverted, so that the upper end 2l of the passage-way A16 projects beyond the shoulder 22 ofthe wall 18. The valve is adapted to reduce the danger of clogging by the cofeegrounds.

Vhen the maker is in use, the holder is lslipped into' the strainer, as shown in Fig. 3,

and holder'are then attached to the mouth of thejvessel bythe handle 7 and the open end of the strainer pressed down over the outside It is obvious that vwhen the coffee-maker is in use the coffee may be prepared by any of the usual methods-t'. e., boiling water may be poured upon pulverized coffee or either pulverized or granulated codee may be boiled in the vesseland that the strainer may be adjusted to the maker after the codec and Waterare in the vessel. After the coiee has been made and the strainer and holder closely fitted in the mouth of the vessel, as shown in Fig. 1, the vessel is tilted or inverted with the tapering end in the coffee-pot, and the cottee fiows into such receptacle ready for use. When the coffee is emptying from the maker, the coffee-grounds gather on the strainernear the mouth of the vessel, leaving the inner end of the strainer practically free from grounds, and thus expediting the Lflow of the coffee.

ISO

By constructing the strainer and holder so that the larger end of the strainer enfolds the outer surface of the ange 2 and the collar 6 of the holder presses the strainer against the inside of said flange a tightjointis produced which prevents the coiee from leaking around the ange. To remove the strainer, its open end is sprung over the upper edge of the collar 6 to the position shown in Fig. 3. The holder and strainer are then lifted from the mouth of the receptacle by the handle 7.

Having described my invention, What I claim as new, and desire to protect by Letters Patent, is-

1. A device of the class described, consist# adapted to eni'old said flange, and means for holding said strainer in the mouth of the Vessel.

3. A coffee-maker closed at one end and terminating in an opening at the other, a flange surrounding said opening, an automatic valve in said closed end, substantially as shown and described, a strainer surrounding a holder in said opening, an expansible ring at the open end of the strainer adapted to clasp the strainer and outer surface of said flange together. l

4. A coffee-maker consisting of a vessel closed at one end and tapering at the other to an opening, a valve in the closed end of said Vessel, a tapering strainer reversed in said opening, and means, for attaching said strainer in said vessel, consisting of a skeleton holder Within the strainer and split ring around the open end thereof.

In testimony whereof I have signed my name to this specification in the presence of two su bscribing Witnesses.
