H. F. LENZ PEPPER MILL Filed Dec. 19. 1950 Sept. 7, 1954 HIGH EZE/vz IN V EN TOR.
Patented Sept. 7, 1954 UNITED STATES ATENT OFFICE PEPPER MILL Application December 19, 1950, Serial No. 201,655
3 Claims. (Cl. 241-468) This invention relates to a grinding mill of the type commonly known as a pepper mill and used to grind spices and other coarse granular material which it is desired to reduce more-orless to a powder. Such a device serves as well as a storage container for the grindable material which conveniently is only ground and emitted from the container a little at a time as needed.
It is an object of the invention to provide such a grinding mill having ready adjusting means for changing at will-even during operationthe grade of fineness to which the material is ground.
Still another object is to construct a compact,
handable mill which is easily assembled and dissembled for either fabrication, storage or cleanmg.
Yet another object is to provide such an improved grinding mill embodying a bottom outlet having vertically adjustable grinding means disposed therein, which means at the same time serve as a closure for the outlet when not in use, and which outlet can be further sealed against entrance of air by merely standing the mill on a flat surface.
Other and further objects and advantages of my invention will become apparent from the drawings and the specifications relative thereto.
In the drawings: 7
Figure 1 is a side elevational view of my spice mill.
Figure 2 is a vertical sectional view showing the internal construction thereof, with portions seen in side elevation.
Figure 3 is a transverse sectional View taken through the mill along the line 33 of Figure 2. Figure 4 is the bottom plan view of the mill.
Figure 5 is an exploded prospective view of the grinding member and the tubular bushing within which it works.
As here illustrated my invention is embodied in a handable housing It formed of a tubular side wall l2 disposed between a top M and bottom It closure. The top closure is formed with an arcuate or dome-shaped upper surface i 8 which at its edges is turned down to form a peripheral lip which snugly overlies the top edge 22 of the side wall. The under-face of the top is formed with three diametrically aligned projections or bosses, the central one 2d of which is axially apertured and provided with internal screw threads 26. The two lateral bosses 28, are provided with downwardly opening sockets 32, 34 which are in turn also threaded.
The bottom closure I6 is formed with outwardly projecting upwardly opening, substantially U-shaped footing rim 36 which receives the lower edge 38 of the side walls 12 in the groove thus formed. Along the inner face of the side wall, the bottom closure extends upward parallel thereto in a cylindrical section 40 which is terminated at the top in a horizontal platform 42 which serves as a floor for the inner chamber 44 of the housing. The floor 42 is likewise apertured at three places in alignment with the corresponding bosses and apertures of the top clo sure I4 thereabove.
Fastening means such as a pair of bolts 46, 48 are inserted through the lower side apertures 50, 52 of the floor, and their upper threaded ends received in the corresponding sockets 32, 34 so that with their enlarged heads 54, 56 pressed in abutment against the lower face of the floor 42, the opposing closures It, It are thus held securely against the top and bottom edges of the tube 52 so as to form an inner spice chamber 44. Access to the chamber 44 may be had without dissembling the device, by means of a swinging or sliding cover panel 58 in the top closure (Figure 1). Access is also afiorded by other means as will be noted hereinafter.
The central aperture 60 in the fioor 42 is provided with an inner peripheral step 52 upon which is fixedly supported a tubular busing 64 having an upper shoulder 66 correspondingly dimensioned to the step 62 so as to be press fit therein. Internally the tubular bushing is provided with an upper funnel-shaped mouth 68 which is succeeeded by a dependent channel section it. The latter is formed with a peripheral series of longitudinal extending fiutings or grooves 712 (Figure 5) which continue to the lower edge thereof.
A bearing member 16 is mounted in the central aperture of the top M by means of an externally threaded shank 78 which engages the threads 26 of the boss 24. The top of the bearing is provided with an outwardly flanged head 80 having a downwardly extending annular skirt 82 which is laterally spaced apart from an unthreaded portion 813 of the shank so as to define a groove 86 therebetween. A helical spring 88 is partially housed in the groove, extending down the shank beyond the same so as to abut against the arouate surface 3 of the top closure. The spring bears upwardly against the head 8i] so as to hold the bearing in a substantially permanent position at whatever level of elevation it may be set by screwing it up or down within th box 24.
Within the central chamber 44 there is located a central shaft 9t axially traversing the chamber and having an upper section 92 of reduced diameter which is rotatably received within a corresponding aperture 94 of the bearing IS. The upper terminus 96 of the shaft is externally threaded and receives thereupon in screw threaded engagement successively an operating lever 98 and a cap screw I90. A hand hold or handle I02 extends upwardly from the outer end of the lever 98, being freely rotatable therein by means of a stub shaft I04. The cap screw I60 mounted upon the end of the shaft 90 serves both to mount the operating lever 98 on the shaft and to hold the central section of the latter in uplifted position, that is with its intermediate shoulder I04 in abutment with the lower end of the threaded shaft I8. Accordingly, by screwing the bearing I6 up or down within the boss 24, the shaft 90 is correspondingly raised or lowered within the spice chamber for a purpose which will be subsequently apparent. However, tension of the spring 88 between the top closure I4 and the bearing I6 restrains the latter from simultaneous rotation with the bearing and shaft.
The lower extremity of the shaft 9% is also radially restricted and externally threaded so as to receive thereon successively a disk I06 and grinding member I63, the latter being threadedly mounted thereon so as to lock the disk against the shoulder I it] of the shaft. The grinding member is generally frustro-conical in outline and with its larger diametered portion disposed adjacent the bottom of the bushing 64. The tapered sides of the member are formed with arcuate fiutings or ridges I I2 disposed thereabout in a general helical or whirling pattern. The disk 5% is formed with a pair of outwardly opening cutouts II3.
As may be seen by reference to Figures 2 through 5, the grinding member I08, even in its largest diameter at I it is of lesser diameter than the depending cylindrical channel section It, in which it is adapted to turn, so that it is possible merely by unthreading the bearing I6 by means of the flanged and most desirably knurled head 80 thereof, to retract said grinding member en- H tirely through the cylindrical section Ill. The mill may thereby be readily filled from the bottom side, and the bearing I6 rethreaded so as to substantially close the opening of said cylindrical portion I0 by means of the grinding member before righting the mill.
The disk I06 functions as a compression memher in that material to be ground, after passing through the openings II3, is substantially prevented from surging upwardly back into the main chamber M by virtue of the grinding movement of the member I08. l he material to be ground, or in the course of being ground, is thereby substantially compacted and forcibly retained within a chamber defined by the interior walls of the bushing 64, the fluted surface I I2 of the grinding member and said disk I05. As ground material is emptied from said last defined chamber, additional unground material comes through the openings I I3. Such material also comes through said openings at every opportunity permitted by the normal turbulence and jostling of the material being ground below the disk I06, Positive cutting action is thus achieved and is accentuated by the whirl-shaped flutes II2, which have a substantial threading action.
The verticality of the flutes 'IZ' permits the ground material to drop freely from the grind-ingchamber bushing 64, regardless of the position of relative elevation of the grinding member I08 4 therein, so that a residue of ground material is not retained on the flutes I2 as would occur if such flutes were spiral or other than perpendicular.
The disk I06 also serves to prevent forcing or leakage of the partially comminuted material within the grinding chamber, i. e., within the bushing 64, as might normally be imposed by the weight of the superincumbent material in the main chamber 44, whose weight for such undesired purpose is, in the instant invention, effectively borne upon the disk IIJB during non-use of the mill.
Accordingly, it will be seen that the spice or other material that passes the disk I06, either along its edges or through the openings II3, will fall in the space between the whirling ridges I02 of the grinder, and the axial ridges T2 of the bushing, and consequently will be ground finer the further down the frustro-conical surface it travels until it is moved out past the terminal edge i It of the grinder and dropped through the outlet mouth I I6 of the bushing. Thus the fineness of the material emitted will be determined in a large measure by the elevational position of the grinder edge II4 along the bearing channel. If it is lowered further from the position in Figure 2, the material coming out will be increasingly coarse, whereas if it is raised from that position the material will be ground finer before being passed out. Accordingly, it will be seen that this can be readily regulated by axial adjustment of the whole central assembly consisting of grinder H18, disk I93, shaft 90, bearing member "I6, operating lever 93 and cap nut I92; this adjustment being efiected by screwing the bearing I6 in one direction or another so to raise or lower the assembly in relation to the top closure I4.
In such movement all the elements carried on the shaft 98 maintain their same relative position to the shaft and to the bearing. Consequently, the size to which material is being ground by the device can be changed at will and without dissembly of the parts or without affecting any quantity of unground material in the chamber. At the same time the unit is comparatively simple and economical in construction and, if required, can be quickly dissembled for cleaning or repair.
While I have herein shown and described my invention in what I have conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of m invention, which is not to be limited to the details disclosed herein, but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices.
