7 Application filedDccember 4,1886. Serial No. 220,661; (No model.) l d To all whom it may concern.-
Be it known that I, ANTON DOBLER, of the city, county, and State of New York, have invented certain new and useful Improvements in Grinding-Mills, ofowhich the following is a specification. V
The dust created by the malt-crushing mills used in breweries forms when mixed with air an explosive body, the ignition of which has frequently causedgreat damage by fire.
The object of this invention is to provide. a
malt or grain mill in which dangerous explosions are avoided;
In the accompanying drawings, Figure 1 represents averticalcentral section of a malt or grain mill provided with my improved means for preventing explosions. Fig. 2 is a plan of the lower part of the same.
Similar letters of reference indicate corresponding parts. 7
Referring to the drawings, A represents the supporting-frame of 'a malt-crushing mill; B B,the crushing-rolls; G, thecollecting-hopper,
and D the conveying-trunk of a malt-crushing mill of the usual construction.
In the trunk D is arranged atone side an inclined deflector, E, and at the other side an inclined valve, F, which is pivoted to the opposite side wall of the trunk D, and which latter abuts against the lower edge of the de- '9, that turns in asocket, g, of the supportingframe A. In place of the spiral spring 9, a balanceweight may be applied to a cord, which latter is attached to the crank-arm f and passed over a pulley; or any other suitable equivalent device may be used by which the valve F is pressed with a certain force against the deflecting-plate D. The tension of the spring 9 is so adjusted that the valve prevents the flow of the crushed malt and supports a sufiicient quantity of the same, so that the malt fills entirely the space below and comes in contact with the lower surfacesof the crushing-rolls BB and above-the valve F, 'asindi-- cated in liig.v 1. When the pressure 0f the malt collected above the valve F overcomes the tension of the spring 9, the valve isvslightlly opened, so asto allow some of the malt to escrushed malt is Supplied by the crushing-rolls B B. The space below the crushing-rolls is thus kept continually filled'with crushed malt,
which is discharged by the opening of the valve in proportion to the pressure exerted thereon. As the space between the rolls B B in the collecting-hopper and upper partof the trunk is filled with malt, no air-space is formed in which the dust from the malt can form an explosive mixture; The crushed ornalti acts,
' therefore, as'a fillerlforl the spacebelow' the rolls and as a "stopper for closing the conveying-trunk. As no explosive mixture can be formed in or near the mill, no explosion can occur in the room where the mill is located, nor in the conveying-trunk, so that the 'dan-- ger of fire from this source is entirely obviated. The valve F oscillates under the-varyi ing pressure exerted by the crushed malt thereon and permits the uniformpassage of the maltfrom the rollers B B to the collectinghopper G and from the same to the conveying. trunk. s 4
Having thusdescribed my invention Iclaim as new and desire to secure by Letters Patent- In a malt or grain mill, the combination,-
withthe crushing-rolls, of acollecting -hopper V below the rolls, 'a conveyer-trunk connected-to the discharge end of said hopper, a valve in said trunk,and a spring normally holding said filled with apassing mass of crushed grain, which excludes therefrom the ingress of air and is discharged in predeterminedquantities.
