' GRINDING-MILL.
Specification of Letters Patent.
Patented Apr. 15, mm
Application filed. April-20, 1918. Serial No. 229,809.
To all whom it'may concern:
Be it known that I, GEORGE E. SOVEREIGN, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented a new and useful Grinding-Mill, of which the following is a specification.
The 7 device forming the subject matter of this application is a grinding mill, and one object of the invention is to provide a compact mill wherein the grinding mechanism is located on one end of a motor which has its shaft disposed vertically, the motor being upheld by a pedestal or other suitable. support.
Another object of the invention is to provide novel means for adjusting the space between the grinding disks.
It is within the province of this disclosure to improve generally and to enhance the utility of devices of that type to which the pres ent invention appertains.
With the above and other objects in view 4 which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawings Figure 1 shows a longitudinal sect-ion, a grinding mill constructed in accordance with the invention, parts appearing inelevation;
Fig. 2 is a cross section on the line 2-2 of Fig. 1.
Fig. 3 is a sectional view enlarged from Fig. 1. 7
In carrying out the present invention there is provided a motor 1 which preferably is driven electrically, the motor being supported on a tubular pedestal 2, the motor including a part 3 received within the upper end of the pedestal and held therein by any suitable means indicated at 4. The motor 1 includes a vertical shaft 5. A screw 6 is threaded in the bottom portion of the part 3 and is held in place by means of a lock nut 7, the screw supporting aball thrust bearing 8. A bushing 9 may be inserted in part 3, around the shaft 5 and above the thrust bearingS.
A hollow top 10 is mounted on the motor 1 and is secured thereto, the top including a lateral discharge chute 11. The top 10 comprises a bearing 12 within which is located a bushing 14 receiving the motor shaft 5. The motor shaft 5 has a collar 27 received within a flange 28 constituting a part of the top 10. A disk 23 is attached to the shaft 5 and is supported on the collar 27, the disk having a depending flan e 29 surrounding the flange 28 of the top. he disk 23 is provided with an upstanding neck 24 receivlng the motor shaft 5. A grinding disk 22 is secured to the upper surface of the disk 23.
There is an annular neck 15 on the top 10. The numeral 17 marks a cap having a depending fiange 30 surrounding the neck 15, the construction being such that the cap 17 may be raised and lowered as hereinafter described. At 25 there appears a hand wheel threaded on the outer surface of the flange 30 of the cap, the lower surface of the hand wheel 25 and the cap being machined so that the cap supports the hand wheel 25 for rota.- tion. Studs 16 are mounted at their lower ends in the neck 15 of the top 10 and pass slidably through the cap 17, there being compression springs 26 interposed between the heads of the studs 16 and the outer surface of the cap 17. A grinding disk 21 is secured to the lower surface of the cap '17 coiip'erating with the grinding disk 22. A hopper 18 is secured to the cap 17. A slide 19 reciprocates on the cap 17 and concludes the passage of material out of the hopper 18, the slide being held in adjusted position by means of a thumb screw 20 or the like.
In practical operation, the material in the hopper 18 passes downwardly between the neck 24 and the inner edges of the grinding disks 22 and 21, the material passing between the grinding disks and ultimately out of the chute 11,
The hand wheel 25 may be rotated to raise or lower the cap 17 and when the cap 17 is raised or lowered, the grinding disk 21 will be spaced accordingly from the grinding disk 22, thereby to regulate the fineness of the material. The springs 26, exerting a downward thrust on the cap 17, serve to hold the hand wheel 25 engaged with the top 10.
One of the advantages of the structure formingthe subject matter of this application is that the device is exceedingly com-- pact, comprising the pedestal 2, the motor 1 supported on the pedestal and having a vertical shaft 5, and grinding means on the upper end of the shaft 5.
Having thus described the invention, What is claimed is 1. In a device of the class described, a top member having a neck; a cap including a flange mounted to slide on the outside of the neck; a hand Wheel threaded externally on the flange co-acting With the top; a fixed grinding disk carried by the cap; and a rotatable grinding disk co-acting With the fixed grinding disk. V
2. in a device of the class described, a top having a neck; a cap having a flange surrounding the neck slidably; a'hand Wheel threaded on the flange and supported by the top; spring means for depressing the cap to maintain the hand Wheel in, engagement with the top; a fixed grinding element car--- 23 ried by the cap; and a rotatable grinding element co-acting With the fixed grinding element.
3. In adevice of the class described, a top having an upstanding neck; a cap having a depending flange slidable on the exterior of theneck; a hand Wheel threaded on the flange and supported by the top; studs carried by the neck and passing slidably through the cap; springs assembled with the studs and exerting 'a pressure on the cap; a fixed grinding element carried by the cap; and a rotatable grinding element co-acting with the fixed grinding element.
In testimony that I claim the foregoing as my oWn, I have hereto aiiixed my signature in the presence of two Witnesses.
GEORGE E. SOVEREIGN.
