HAMMER ADJUSTMENT.
To @ZZ whom t may concern.'
Be it known that I, JOSEPH K. BLUM, a citizen of the United States, residing at Greenburgh, in the county of Vestchesterl andState of New York, have invented certain new and useful Improvements in Hammer Adjustments, of which the following is a specification.
This invention relates to an improved assembly and adjustment for hammers o1' beaters of the type used in Crushers or dis-A integrators, permitting the hammer wear to be compensated for in a practical and reliable manner.
One of the objects' of the invention to provide a simplified construction having a minimum number of parts which also admit of the adjustment of the hammers with a minimum 'expenditure of time and labor. In that connection the inventiony also conteniplates the provision of a heavier andmore substantial construction which permits of better distribution and arrangement of the parts subjected to' the greatest wear, thereby materially increasing the life and insuring` proper functioning of the various parts under the most rigorous operating condi-` tions.
A further object of the invention is to provide a construction which, by reason" of its relatively few parts, permits of facile taking apart and reassembling to effect the desired adjustments.
With the above` and other objects in View which will more readily appear as the nature of the invention is better understood, thc same consists in the novel construction, coinbination'and arrangement of parts', hereinafter more fully described, illustrated and claimed.
A preferred and practical embodimentof the invention is shown in the accompanying drawings, in which: l j
Figure l is a side elevation of'al disin# tegra'tin'g rotor embodying improved hammer adjustment.
Figiire' 2 is a vertical sectional view thereof. i l

\ Figure 6` is a detail perspective View ofwel. modified form of journal pin for use in cohnection with vthe disc shown in Figuife; igure 7 is a diagram illustrating the adjustment. e Y
SimilarA reference characters designate corresponding parts throughout the several figures of the drawings. e l u .In the operation of disintegrating appz'zratu's of the hammer mill type, it visa well knownefact that thel hammers are suloje'voted` to considerable wear on their crushingv or grinding edge, and, after a period of use, frequently become wornl to such an extent that the radial distanceof the crushing edge from the axis of the rotor isconsiderably shortened. Accordingly, an object of the present invention, as previously indicated, A4is to Vprovide novel means for adjusting the relative position of thek hammerin such fa manner that its crushing edge will be jected outwardly to such an extent that its full efficiency will be restored. My forn'ier .Patent iva-1,185,619; dated June c, 1917.6
shows a practical and reliable construetiu i for compensating for such wear, and the present invention 17s intended to be an ln'ij provement upon the construction shown in that patent. y y j Therefore,` to that end, the present con.- struction embodies in its organization "a novel and simplified assembly of parts which primarily consists of a pair of journal plates Or discs l--l suitably keyed on the rotor 'or disintegrator shaft 2 and having at spaced intervals a plurality 'of adjustment openings designated generally as 3, and hereinafter more fully described infdetail, for accommodating a novel type `of adjustable journal pinsl. The saidjournal pins 4 are provided with eccentricb'earing studs 5 for engaging thebearing eyes 5a at the end of the` arrmls 6 of the hammers 7, and Amay be locked Or held in position in the discsl by thev locking lianges 8 of a split spacing cellar 9,y which, in addition to locking the adjustable journal pins' invv place maintains'v the journal discs in proper spaced'relation.'` "l In cdnnectio'n withl the onstructinabve described it is pointedr out that one of the distinctive features ,df the, prsent inten? non resides is prdvfdiffg' ai@ unitary jaar:
nal discs 1-1 for receiving the adjustable r adjustment .without the necessity of manipulating any other part of the construction.
The foregoing description emphasizes the l improved general assembly for the entire construction, but other novel and distinctive features reside in the adjustable journal plates or pins 4 and the means for mountving the same in the journal discs to prevent undue play, thereby materially adding to the stability of the entire assembly. In that connection it may be observedthat the ad-V justment openings in the discs l-'-1 may -consist of the square or equivalent noncircular shaped locking portion opening` at the outer facel of the disc, .and a communicating circular portion forming a seat or socket 11 opening through the inner face of the disc. The square portion 10 referred to is adapted te receive the square ylocking body portion 12 of the adjustable journal` pm 4wh1le the round head portion 13 of the latter fits tightly in the socket 11, thereby preventing relative movement or play between the pin 4 and the discwhile the noncircular body portion 12 prevents relative rotary movement of the pin in the opening.
As4 will be v*observed .from Figure 3 the eccentric bearing stud 5 of the journal pin is located at one end of the squarer locking portion 1,2, and as will be observed from Figures l and 7, the diagonale of the square y portion o f the openings 3 are coincident with the radii of ythe Ydiscr at equi-distant 'points .throughout 'its circumference. Thus, when the' parts'are originally assembled the bearing stud 5 may be supported relativelyv close .to the axis of the shaft 2 ofthe rotorr i. as shown at a in Fig-7, or in other Words,
the length of the radius of the point of piv-` otal support for'the hammer 7 with reference to the axis ofthe rotor will be the shortest, and, as the hammer wears, the bearing stud 'ma'y be shifted 900, or 180 to the positions marked Z) andro *whichl will. havethe effect of lengthening the hammer and bringing it closer to the bottom of the disintegrator. 1` I 1 AF gures .5, and 6 show a modification of the construction hereinshown wherein the relative adjustment of the hammers may be efectedbyj a different form of non-circular part on the adjustable journal pin. That is to say, instead of a square body portion v the pin 4a may be provided with a round body 12a adapted to t in a circular opening 12b inthe disc, the said bodyl2"L and edges of the opening 12b being provided with complemental notchesl 1.2e which may register to receive a locking pin or pins 12d. By increasing the number of notches in the circumference of the round portion 12a and correspondingly increasing the notches in. the edges of the opening 12b, it will be apparent that relatively minute adjustments may be readily effected to obtain variousdehr grees of fineness of the crushed product. f
F rom the foregoing it will be apparent that one of the distinctive features of the present improvement is a novel rotor construction which is capable of being readily taken apart and likewise reassembled for effecting the adjustment vof the hammers which are mounted on the eccentric bearing studs 5 of the adjustable journal pins 4. Also, in connection with the pins a distinctive feature is the eccentric stud and the non-circular part for interlocking withvthe disc to prevent accidental relative rotary movement of the pin in the disc which would change the operating radius of the hammer.
However, on ,the other hand when it is' desired to effect the adjustment of the hammer, the pin may be readily released and turned to thereby move the same radially outward.
It will also be noted that the split spacing collar provides simple and practical means for releasably locking the pins in the discs, and insures the vproper seating of the enlarged head portions 13 thereof in the sockets of the discs vwhich ,prevents looseness or undesirable"-play that would otherwise effect the proper functioning of the hammer.
Without further descriptionv it is thought that the many features and advantages of the present invention'will be readily apparent, and it will of course be understood j that changes .in the form, proportion, and minor details of construction may be rresorted to, without departing from the spirit of the invention or scope of the appended claims. e
