MACHINE` FOR PEELING, POLISHING, AND CLEANING COFFEE.
SPECIFICATION forming part of Letters Patent No. 402,318, dated April 30, 1889. Application filed October 20, 1887. Serial No. 252,893. (No model.) Patented in Costa Rica July 29, 1887.
inafter fully described, and pointed out in the v claim. l
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.
Figure l is a vertical section of the machine, showing the power mechanism and a fan or winnowing apparatus. Fig. 2 is a section on Fig. 3 is a view of the peeling and polishing apparatus with the casing and hopper in vertical section, and Fig. t
is a view of the casing and hopper with the vibrating screen and fan-casing in vertical section. Y
In setting forth the construction of the ma- 'chine I will commence with that portion thereof in which the coffee is fed to the machine and is peeled and polished.v ,For this purpose the casing F, preferably of sheet metal, is mounted on a platform, C2, supported byuprights W, resting in a base-frame, W. The platform C2 is formed with an elevated portion, C2, through which passes a shaft, a, hav# ing its upper end mounted in a sleeve, 0.', sup#l ported by arms or brackets o', and its lower end resting in a sleeve, c', mounted in a bearing, L, supported by the arms L'.
Within the casing F an inverted cone-frustum, A2, is mounted on the shaft a by means v of the collars o3, secured to the solid frame A3, upon which is stretcheda web or wire netting, a4, of suit-able iineness, attached at its upper edge to a tapering top, A, preferably of metal, and at its lower edge to a base-piece, A4. The cone-frustum A2 is adapted to rotate within and is fconcentric with a iixed cone-frustum, B, of wire-netting of suitable texture and iineness, which is mounted upon Vlatforml C2, and securedbv nuts b2.
a framework, B', having its base B2 resting on the elevated portion C3 of the platform C2.
The upper part of the frame-work B' is braced by means of rods b2, connecting it with the The cone-frustums A2 and B are located, relatively -to each other, so as to form a space, B3, be-
tween them for the passage of the coffee.
The cone-frustum A2 is provided on its outf side with diagonally-extending rods A', for a purpose hereinafter explained.
4It will be seen that the conesfrustums are surrounded by a hollow space, F2, within the casing F, the bottom of which is formed of curved blocks J, of wood or other suitable material, which are provided'with openings d, connecting with conduits D, for the passage of the 'material dropping from the cone-frustulns.
The upper partof the casing F is provided with flaring sides, forming a hopper, E, which has an inclined bottom, H, provided with openings P and slides P', which admit the coffee. The upper ends of the shafts a are covered and protected by means of the extended portion of the bottom H, provided with the cap T. It will be seen that the arms or brackets b'are secured tothe upper part of the frame B. I
Below the base A4 of the cone-frustum A2 is a space, D', in which stirrers or arms t, mounted on the shaft a, are adapted to rotate and stir the coffee descending between the conefrus turns. The space D' connects bylineans of a conduit, I, with a vibrating screen, K, mounted on swingingV arms k, pivoted to the frameworlcand having'ian inclined chute, X. The vibrating screen K is actuated by means of eccentric-rods F', mounted on the shaft C, having a suitable band-pulley, o, (see Fig. 1,) the shaft C carrying the fans P2 within the casing V, whereby a current of air is driven through the opening h beneath the vibrating screen K.
The shaft c is driven by any suitable mechanism. For the purpose of illustration I have shown it driven by a bevehgearing, U, actuated Vby a shaft, Z, mounted in crosspieces R of the base-frame, and provided with band-pulleys m and n.
The cone-frustum A2 is adjusted by means IOO of a set-screw, g, bearing against the lower end of the shaft a, whereby the space between the cone-frustums may be increased or diminished, so as to allow a greater or less amount of coffee to be located therein. The shaft c passes freely through the gear-wheel U, so as to allow it to be raised or lowered to adjust the cone-frustum A2, and the said gear-wheel is locked to the shaft by the spline l on the said shaft.
The operation of my device is as follows: The coiee is placed in the hopper E and its liow through the outlets P is regulated by means of the slides P. The coffee, passing through the space BB between the cone-frustums A2 and B, is rubbed between them by .means of the conc-frustum A2, rotating on the shaft a, and by means of the diagonal arms A', and on reaching the space D is agitated by the stirrers t, and passes olf by means of the conduit l onto the vibrating screen K. In its passage between the cone-frustums A2 and B the dust and a majority of the parchment fall through the nettingA of the conefrustum B into the chamber F2 and onto the curved bottom J thereof and passes off through the conduits D. The coffee, falling upon the shaking-screen K, is cleaned by the vibration thereof` and the winnowing action of the fans P2 in the casing V. The dust, falling through the screen K, drops onto the chute X and is carried along by its vibration.
By this machine I utilize the pressure of the mass of coffee entering through the openings P and produce harder or lighter rubbing of the grains upon each other and the walls of the inner and outer cone-frustums, which pressure and rubbing can be increased or diminished in intensity in two ways-rst, by opening or closing (more or less) the slides P', and, second, by raising or lowering the inner cone-frustum, thus enlarging or diminishing the space between the two cone-frustums. The inner cone-frustum, rotating from the time the grains of coffee enter the space between the two cone-frustums, and the cone-frustum being of conical form, Various beneficial effects are produced upon the coffee in its transit to the outlet below by reason of the following considerations: First, the grains of coffee in contact with the face of the rotatiugiuner cone-frustum tend to fall outward; second, the grains of coffee in contact with the outer cone-frustum tend to go upward, and would do so if the walls of the outer cone were smooth; and, third, the grains of coffee pressed down by the weight of the mass of coffee above are forced to descend gradually, the inner cone-frustum being large above and small below. The coffee when it first enters the machine, following the motion of the said inner cone, travels in a diminished spiral. Consequently the coffee moves faster at the top than below, the speed gradually lessenmg as it descends. As the result of these diverse tendencies, there is friction amongthe grains of coffee and against the walls of the two cone-frustums, producing the desired result of peeling-that is, rubbing off the parchment or skins and polishing all the grains of coffee, whatever may be their varying sizes.
Coffee after being dried has three coatings or parchment-like skins-first, a thick exterior parchment, which contains both halfgrains of the berry; second, a secondary parchment covering each separate half-grain, and, third, a thin parchment below the parchment last mentioned. With my machine the coffee with all three of its parchments can be readily treated.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
In a machine for cleaning and polishing coffee, the combination, with a casing provided with a hopper at its upper end and with openings in its bottom, of a stationary inverted cone-frustum of wire-gauze, supported on the casing, a rotary inverted conefrustum covered with wire-gauze, arranged within the stationary cone-frustum with a space between them, and provided with diagonal rods on its outside, and a spout leading from the space between the said inverted cone-frusta, substantially as herein shown and described.
