B. KUMAGAE PERCOLATOR TOP PROTECTOR Filed May 24-. 1926 BY WZZ M A TTORNEYS.
Patented Nov. 8, 1927.
BUNTARO KUMAGAI, F LOS ANGELES, GALXFORNIA.
PERCOLATOR-TOP rnocrnoron.
Application filed May 24, 1926. Serial No. 111,207.
This invention relates to a protector for percolator tops, and pertains more particularly to a deflector and spreader element which is interposed betweenthe upper end of the riser tube and the top.
It is common practice to construct percolators with a dome top of glass, into the chamber of which the hot liquid is discharged from the riser tube. The released fluid is spread by falling downwardly into the filter cup. The spreading is not uniform in such structures. Furthermore, the hot liquid impinging upon the glass dome causes strains in the material thereof which often result 1n breakage of the glass. The present invention has for its primary object the provision of a spreader plate against which the liquid from the tube impinges, being sprayed thereby over the filter cup. Another object of this 0 invention is to provide a device of the character described which may be detachably mounted in the top and will serve to lock the top against displacement from the cover.
These objects together with other ob ecte and corresponding accomplishments are ob tained by means of the embodiment of my invention illustrated in the accompanying drawing, in which:
Fig. 1 is an axial section through a well known type of percolator with my improved protector mounted therein; Fig. 2 is a section as seen on the line 2-2 of Fig. l on an enlarged scale; Fig. 3 is a fragmentary view as seen looking in the direction of the arrows 3 of Fig. 2; Fig. 4 is a bottom plan view of the protector detached from the top; and Fig. 5 is a section as seen on the line 5-5 of Fig. 2.
Referring with more particularity to the drawing, the coifee pot is indicated by 10, it being provided with a spout handle and having the usual neck 11. Hinged to the pot so that a downwardly extending flange may enter the neck is a cover 12. At the top is an aperture bordered by an inwardly turned flange 13. The usual glass top or dome is indicated by 14. This top has a cylindrical lower portion adapted to slip within the flange 13. A stop collar 15 engages the marginal edge of the aperture. Projecting from the outer wall of the top are lugs 16 for the purpose of locking the top in place. There are indentations in the flange indicated by 17 to permit the passage of the lugs in lacing the top in position. The effect is to orm a bayonet'joint, the top is slipped into position, the lugs 16 being registered with indentations 17 and being passed below the flange 13 through the indentations. The top is then rotated into position such that the lugs 16 are out of registration with the indentations. The lugs then serve to hold the top from detachment from the cover. A riser tube 18 is mounted upon a base 19, and carries a filter cup 20. The filter cup contains the ground coffee.
The construction just described is that of a common type of percolator. The liquid passes up the riser tube and is commonly projected against the under side of the dome or top 14. It then drips upon the ground coffee in the cup and is filtered therethrough passing back into the body of the pot. Obviously, the hot liquid striking the glass top 14 may cause the latter to break. F urthermore, there is only a limited distribution of the hot liquid because of the character of the top.
I have provided a bridge which is attached to the top and consists of an impact plate 21 having downwardly extending arms 22 which are spread. The impact plate and arms are preferably made of some resilient material such as a spring metal. The arms 22 have return bends or fingers 23 arranged to slip over the lower rim of the top. These fingers are provided with apertures through which the lugs 16 may extend. The device is such that it may be slipped into position, looking over the lugs so as to hold the protector 1n place. At the same time, the fingers serve to prevent detachment of the top, as they will not permit the lugs to pass through the indentations.
The hot liquid is projected from the end of the riser tube and strikes the impact plate 21, by which it is spread. The distance of travel of the liquid from the top of the riser tube to the impact plate and then to the filter cup is lessened. The loss of heat from the liquid is also decreased. This results in more eflicient operation of the percolator. Furthermore, there is a. protection of the glass top against breakage by the hot liquid.
What I claim is:
1. A device of the class described comprising an impact plate having resilient downwardly and outwardly extending arms provided with fingers to engage the outer surface of a percolator' top, said fingers being provided with lug receiving apertures.
2. In combination with a percolator having a coverand a glass top detachably secured thereto b a slip-on and a bayonet joint, the lugs 0 said joint being on said top, an impact plate having arms downwardly and outwardly extending therefrom and pro vided with upturned fingers having lug receivin apertures to engage the outer surface 0 the percolator top. Y
3. In combination with a cover of a percolator having a removable glass dome, a 10 bridge detachably secured to the percolator top so as to span the chamber therein and having an impact area adapted to register with the percolator tube.
In witness that I claim the foregoin have hereunto subscribed my name this th day of May, 1926.
