ADOLF SPINNER in OFFENBURG. Regulator for coffee burner.

Patented in the German Empire on October 8, 1885.

It is well known that coffee loses a certain percentage of its value through the roasting process Weight, and the greater the longer it is exposed to the fire.

A well-roasted coffee is around 20 pCt on average. lighter than the unroasted one; weak The roasted loses less, the heavily roasted loses more.

It is therefore possible to determine the degree of roasting after the weight loss has taken place and, conversely, to obtain a desired degree of roasting by only reducing the coffee by a certain percentage runs lighter and then stops roasting, which would be particularly advantageous for larger distilleries, which must be concerned with not just one as evenly as possible to obtain roasted coffee, but also a good degree of roast with minimal loss, because the coffee is sold by weight.

The present apparatus is supposed to automatically stop roasting as soon as a certain weight loss is achieved and thus the desired degree of roasting has also occurred, due to the fact that then the lightened roasting drum lifted by a counterweight, the oven lid turned over and bringing the drum out of the oven to roll it out.

The arrangement of the apparatus is as follows according to the drawing: Fig. 1 is the side view, FIG. 2 shows the rear view and FIG. 3 shows the view from above.

The spherical drum t lies in a cylindrical furnace G, in which the furnace is located below, which is left out in the drawing as not essential for the apparatus. The furnace is provided with a hood ab c de g that can be rotated around pin d.

The crank is not seated on the drum shaft, but on a shaft W ₁ in the bearing / on which there is also. the wheel T ₁ is located, which engages in the wheel r on the drum shaft w. The drum shaft rests at gh , Fig. 1, on the furnace walls, but is also supported by the lever i 0 k , which has its pivot point in ο.

On the drum shaft is the frame ρ q O ₁ q _l p ₁ , which is maintained in a vertical position by the two guides ν and V ₁ , one of which is omitted in FIG. 2 for the sake of clarity, but with ease can move up and down on the rollers χ mounted in the guides (section to AB).

At O ₁ , Fig. 1 and 2, a pin S _{1 is} riveted into the frame, on which the plate W ₂ provided with the square opening u and on it smaller ring-shaped weights, depending on the weight loss suffered by the coffee through roasting should be attached.

Below the frame, a clamp is attached to the hood, in which an adjustable screw O ₂ , provided with a roller u , is attached, which engages in the opening of the plate U ₂ .

On the opposite side of the hood at Z a pulling rope is attached which, going _{over the pulley r 3} , is weighted at T with a weight which tends to move the hood around the pin d into the punctured position (X ₁ b _x C _x d ₁ e _x g ₁ to bring.

Claims (5)

The operation of the apparatus is as follows: First, the empty drum with the frame standing on it and the plate M2 lying on it is balanced by means of the adjustable weight Q. on the lever i ο k, the drum is filled therein and the net weight of the kaife is attached to K. So many weights are then placed on pin S1 that they are equal to the weight loss which the coffee is supposed to suffer from roasting. Once this has happened, the drum is set in motion in such a way that it assumes the direction of rotation indicated by arrows in FIG. If the coffee has lost as much of its weight as is placed at O1, the lever is in equilibrium, but after the slightest further weight loss it is disturbed and the drum shaft is lifted into the slot, Fig. 1. With it, the frame ρ q O1 qx px with the plate M2 and the weights, rises. until the screw O2 can be pulled out from under the plate M2. Then the weight T flips over the hood, the drum shaft, which now has no hold on the front side, rolls along the oblique rails as a result of its direction of rotation The lever i ο k then rests on the support y, Fig. 1. Once the drum has been emptied and filled, the rails s, which can be rotated about the pins S0, Fig. 2, become so The drum shaft is provided with two collars b2 so that it does not fall off the rails when it rolls on the rails. The cover is then closed, and it is closed by inserting the plate Un and the relevant one Weights secured and the roasting started again. Patents τ claims: 1. The union of the coffee burner with a scale i 0 k, Fig. 1, on one end of which the drum shaft rests at i and on the other end of which the weights K and Q. are attached, the former (K) being the net weight of the Coffee, while the other (Q) is used to adjust the empty drum. These scales raise the drum to the appropriate height as soon as the desired weight loss of the coffee has occurred. 2. The frame ρ q O ₁ q _l p ₁ , which is supported on the drum shaft and serves to hold the ring-shaped weights that indicate the desired weight loss of the coffee and are attached at S ₁ . 3. The plate M ₂ attached to the frame ρ q O ₁ q _x ρ _λ at S ₁ and the screw m attached to the furnace cover, both of which serve to keep the furnace cover in place for as long as possible to hold until the desired weight loss of the coffee has occurred. 4. The pulling device \ r T, Fig. 1, which has the purpose of turning over the oven lid, so that the drum and the frame ρ q O ₁ q _} p _{ as a result of the weight loss of the coffee due to the scales i ο k in the appropriate height are upscale. 5. to the pins s _lh Fig. 2, the rotatable rails s wrong lying on which the triggered drum rolls to their destination, and which are lifted so far back has occurred is emptying and filling of the drum, that the drum at its bearing point can roll back. 1 sheet of drawings.
