SPECIFICATION forming part of Letters Patent No. 408,707, dated August 13, 1889.
Application filed January 12, 1889 Serial No. 296,127. (No model.)
To all whom it may concern.-
Be it known that I, HANSON GOODRICH, a
citizen of the United States, residing at Mo- Leansborough, in the county of Hamilton and State of Illinois, have invented new and useful Improvements in Coffee-Pots, of which the following is a specification.
My invention relates to attachments for coiTee-pots; and it consists in certain novel features hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a view showing my improved device in elevation in position within a coffee-pot, the coffeepot being in section. Fig. 2 is a vertical sectional view of the attachment, and Fig. 3 is a horizontal section through the cup. Fig. 4is a detail view of the spring-collar.
Referring to the drawings by letter, A designates a coffee-pot of the usual or any preferred construction, and B designates my attachment arranged within the same.
My attachment consists of a slightly-convex circular supporting or base plate 0, the tube D rising therefrom, and the cup E, secured to the upper end of the tube. The baseor supporting plate-O is adapted to rest upon the bottom of the coffee-pot, and is provided around its edge wit-h radial corrugations or crimps F, so that when the device is in position in the coffee-pot the said corrugations or crimps will form inlet openings, through which the water will pass into the space between the bottom of the coffee-pot and the base-plate, as will be readily understood.
The tube D rises from the center of the baseplate and communicates at its lower end with the space between the base-plate and the bat tom of the coffee-pot, so that the water in said space after being heated can rise through the tube, so as to escape into the cup E, as will be presently more fully described. The said tube D is made in two sections, the lower section G rising from the base-plate and the upper section H fitting over the upper end of the lower section, so that the two sections can be telescoped to adjust the tube to the height of the coffee-pot, or to the height of the water within the coffee-pot, as may be desired. A spring-collar I is fitted upon the lower section and is adapted to bind firmly around the same, while at the same time it can be readily moved longitudinally of the tube by hand. The upper section is supported by the said spring-collar, as clearly shown, the lower end of the said section resting on the collar. The exact construction of this spring-collar is immaterial, and in the drawings I have shown it as consisting of arubberring which will bind around the tube.
The cup E is secured to the upper section of the tube, and has its upper edge in about the same horizontal plane as the upper end of the tube. The said cup is provided with a perforated bottom J, and is also provided with a straining-cloth K. The said strainingcloth K is of proper size to entirely cover the bottom of the cup, and is held in place by the spring-collars or clamping-rings L M, the ring or collar L binding the inner edge of the cloth around the tube, while the ring or collar M clamps the outer edge of the cloth against the side of the cup.
From the foregoin g description it is thought that the operation and advantages of my device will be readily understood. Coffee is placed in the cup and the device then placed in position in the coffee-pot. The coffee-pot is then filled with water to the desired height and the device is ready for use. Upon being placed over the fire the water in the space between thebase-plate and the bottom of the coffee-pot will become quickly heated and caused to boil. It will then rise through the tube, and, escaping from the upper end of the same, will fall over onto the cofiee and willpercolate through the same, so as to extract the strength therefrom, finally escaping through the perforated bottom of the cup to the body of water below. It will thus be seen that a continuous circulation of the water is maintained, so that less heat is required to boil the entire body of water than in the devices heretofore employed, as only a small quantity of the water is acted upon at one time, so that it is rapidly set in motion and its place supplied by a fresh quantity.
My improved device can be applied to any coffee-pot now in use, and can be readily adjusted to the height of the same or to the level of water therein The hot water percolating through the coffee will extract the full strength of the coffee, and at the same time will produce a liquid which will be free of all grounds or other impurities, so that it is not necessary to use any clearing materials.
It may be sometimes desired to have the cup provided with a perforated bottom of a coarse mesh, while at other times it may be preferred to have the bottom of a fine mesh. This object is accomplished by the use of the permanent perforated bottom and the straining-cloth secured within the cup. By removing the straining-cloth the water will pass directly through the perforated bottom,which is of a coarse mesh, while by replacing the straining cloth the water will first pass through the said cloth, which is of a fine mesh.
It will be observed that it is not necessary to provide the attachment with a lid or cover to deflect the rising column of water over onto the coifee, as the lid of the coffee-pot also serves as a lid for the attachment.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
1. The combination of the base-plate, the
tube rising from the base-plate and composed of two sections, the lower section being secured t0 the base-plate and the upper section fitting over the lower section, the springcollar mounted on the lower section and sup- HANSON GOODRICII.
