ATTOR N EY- Patented May 23, 1950 UNITED: STAT ROTOR STRUCTURE FOR HAY MANGLERS OR GRINDERS William Wiley Miner, Jr., Roland Owens, and Ned Ray, Verdon, Nebr.
Application December 14, 1948, Serial No. 65,192
2 Claims. (01. 241-194) Our invention relates to machines of the type disclosed in our application for patent filed October 8, 1946, Serial No. 701,882, and it particularly has for its objects:
1. To provide an automatic means for retaining the pins which hold the hammer blades, etc. in place.
2. To provide a means for latching the pins which hold the hammer blades, etc. in place, which means is effective under the action of centrifugal force but which is easily releasable when the rotor which carries the blades is at rest.
To the attainment of the aforesaid objects and ends invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, and then be particularly pointed out in the appended claims, reference being had to the accompanying drawing, in which:
Fig. 1 is a vertical section and part elevation of a hay mangler or grinder embodying our invention.
Fig. 2 is an enlarged detail vertical section showing the upper pin latch open and the lower one closed.
Fig. 3 is a section-perspective view on the line 33 of Fig. 2.
Fig. 4 is a view similar to Fig. 3 but with the slide in open position.
In the drawing in which like numerals of reference indicate like parts in all the figures, I is the mangler or grinder casing, 2 the truncated housing or cone which has a bottom 3 serving as a top for the casing I.
The drive motor is mounted on the top flange 5 of the cone 2 and has a, shaft 6 which is coupled to the main shaft I of the rotor. The shaft 1 is journalled in suitable bearings 8 and 9 and carries bearing sleeves I 0 and l I respectively.
Mounted between the upper and lower sleeves II] and II are plates I2, I3 and I4 (discs or arms) and spacers I5. These parts are securely clamped together as one by nuts I B threaded on shaft 1. The plates I2 and I3 have aligning apertures II, I8 respectively to receive the pins I9 on which the hammer blades 20, draft blades 2I and spacers 22 are pivotally mounted.
Welded or otherwise suitably secured to the plates I2 and I3 are slide blocks 23 having grooves 24 for slides 26. The blocks 23 also have pin holes '25 through which the pins I9 may pass, the holes 25 aligning with the apertures I1.
26 indicates slides which operate in the grooves 24 to close or open the holes 25. The slides have lugs 21 that operate in and project through slots 28 in the plates I2 and I3, the construction being such that when the slide is retracted (see top slide, Fig. 2) a pin I9 may be passed through the hole 25 into the aperture I l and through the holes 29 and 30 in the blades 20 and spacers 22 respectively and aperture I8, where it is arrested by the slide 26 of the lower latch when its slide is over its hole 25 (lower latch, Fig. 2). The ends of the pin I9 lie flush with the upper face of the upper plate I2 and the lower face of the lower plate I3 as shown in Fig. 2.
Upon rotation of the rotor slide 26 of the upper latch will be thrown radially outwardly and close hole 25 of that latch. Centrifugal force will keep both latches in closed position so long as the rotor is in motion.
When, however, it is desired to remove and replace a blade it is only necessary to move back the latch slides to free the pin and enable it to be pushed out.
From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, operation and advantages of the invention will readily appear to those skilled in the art.
What we claim is:
1. In apparatus of the class described, a rotor having upper and lower plates rigidly secured in spaced relation on a rotatable shaft, said plates having aligning pin holes, blade-carrying pins held in said pin holes and extending from one plate to the other, and centrifugally operated latches on said plates for projecting across at least one end of each pin to retain it in place during rotation of said shaft, said latches each including a radially grooved block fixedly mounted on the plate and having a pin hole in alignment with pin holes in said plates, a slide operating in the groove of said block to open or close said pin hole, said latches being operative under centrifugal force to its pin-hole-closing position for retaining said blade-carrying pins in place.
