United States Patent PORTABLE GRINDING MILLS Carl E. Erickson, Manhattan, Kans., assignor to Viking Manufacturing Company, Manhattan, Kans.
Application February 13, 1952, Serial No. 271,390
Claims. (Cl. 241-101) This invention relates to improvements in portable grinding mills.
The main objects of the present invention are:
First, to provide a portable mill or grinder with a discharge pipe which may be adjusted to any desired angular position relative to the grinder for the delivery of the ground material in the most advantageous manner.
Second, to provide a structure of this character in which the discharge pipe, while being adjustable, is effectively and fixedly supported in its selected adjusted position.
Third, to provide a structure having these advantages which is simple and very economical in its parts.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.
A structure embodying the features of the invention and the manner of carrying out the method is clearly illustrated in the accompanying drawings, in which:
Fig. 1 is a front perspective view of a grinder embodying the features of my invention with the discharge pipe adjusted to one of its operative positions.
Fig. 2 is a vertical section on a line corresponding to line 22 of Fig. 3.
Fig. 3 is an enlarged fragmentary side elevation view from the right of Fig. 2.
Fig. 4 is a fragmentary view in vertical section on a line corresponding to line 44 of Fig. 2
I have illustrated my invention as embodied in a grinding mill of the type shown in the Erickson Patent No. 2,557,344, issued June 19, 1951, but it should be understood that my invention is adapted for embodiment in other mills of this type.
The embodiment illustrated comprises a casting 1 for the hammer type of rotor conventionally illustrated at 2. 3 is the feed chute. The grinder is mounted on a carriage 4. 5 represents the power shaft which is connected to the rotor, the driving connections, not illustrated, being within the housing 6. The casing 1 has an upwardly tapering delivery portion 7 provided with a flange 8 to which the flange 9 of the upwardly tapered elongated delivery spout 10 is secured by bolts indicated at 11. The delivery spout is of substantial length, and constituting a support for the discharge pipe. An annular bearing member 12 is arranged around and fixedly secured to the spout 10, adjacent but in spaced relation to its upper end desirably by welding as indicated at 13 in Fig. 4.
The discharge pipe comprises a tubular lower section 14 and a curved upper section 15. The lower section has a coupling member 16 at its upper end, while the upper section has a coupling member 17 at its lower end. These coupling members are of angle section, their vertical flanges 18 being disposed within the pipe sections with their horizontal flanges 19 projecting outwardly to receive the bolts 20. An annular plate-like bearing member 21 is disposed between the coupling members and clamped thereby. This bearing member coacts with the bearing 12 on the discharge spout to rotatably support the discharge pipe.
The discharge pipe delivers to a collector 22 which is provided with a delivery chute 23 hinged thereto at 24. The collector is further supported by braces 25 which extend from the collector and are attached to the lower section 14 of the discharge pipe adjacent at its lower end at 26. The section 14 has a vertical slot 27 extending from its lower end. Ears 28 are secured to the section 14 at its lower end on opposite sides of the slot as shown in Fig. 3. The threaded bolt 29 is fixedly secured to one of the ears and disposed through the other to receive the clamping nut 30 which has a spacing sleeve portion 31 so that the nut, which is in the form of hand wheel, is positioned for grasping at the side of the pipe.
The rotor 2 constitutes a blower for the ground material which is discharged through the spout 10 into the discharge pipe and delivered thereby into the collector and discharged from the collector mainly by gravity. The discharge pipe is thus supported so that it may be swively adjusted to any desired position, and this permits the collector to be moved completely around the mill as may be desired for the most efiicient discharge. This also permits the mill to be located in the most convenient position for its operation.
The delivery may be to wagons or trucks, feed bunkers or buildings. Also the delivery pipe may be positioned according to wind conditions. The discharge pipe is easily adjusted as it is very effectively supported in its adjusted position.
I have illustrated and described my invention in a highly practical embodiment thereof. I have not attempted to illustrate or describe other adaptations or embodiments which I contemplate, as I believe this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
