To aZZwiwm it may concern:
e it known that I, JACOB WILLIAM SPENSLEY, a su'bjectof the King-of Great Britain, and resident of29 Barton Arcade,
in the county of eansgate, Manchester, ancaster, England, chemical engineer, have invented certainnew and useful Improvements Relating to Rotary Disintegrating,
ulverizing, or Mixing Apparatus, of which the following isa specification.
This invention relates to rotary disintegrating, pulveri'zing or mixing apparatus of are used with interand thematerial is calatlng pins thereon,
by being caused to disintegrated or mixed The present invention has for its object 'to provide an improved construction wherein the pins can be readily securedinposition can be removed therefrom "manner, for replacement Another obj ectof the inn the disks and are f holes formed in :the disks which are provided with bushings adapted to coact with flats formed ends of the holes to eflect and positioning of the pins. A further object of the invention is to permit of the use of plain pins of a hard quality of steel, harder than can be screw-threaded or riveted, which pinscan be secured in position so as not to leave any projecting heads on the back of the disks when revolving in the machine.
The construction according to the invention is shown in the accompanying drawings, wherein z- Figure 1 is a half section of a disks with pins thereon, and
Fig. 2 is a partial plan view to a smaller scale, with th' grooves on the top pair of the e pins and plate shown in dotted lines.
Fig. 3 shows a detail.
pins a are used with plain shallow cylindrical heads 5 of somewhat larger di-.
ameter. Such pins can be formed from rods quality of' steel by cutting on an automatic machine, whereby great acdisks c and d have holes ated sizes formed in concentric circles Fig. 1', around each thevheads Z) of'the pins will be flush against allel to th ,a le way,-as for instance by the screws-M'these'are shown ashaving proyecting heads,
suitable liners or during the driving in of th curacy. andnniformitycan be secured. The
for pins of gradutherein. Theseholes the'same when driven in; this is necessary r as the disks-are dished but the pins are par- The holes are 'madeofsu'ch a size that the pins a are a force-fit or of th re and f-Whichgar0 dished to e turning axis.
driving-tit therein. The heads 6 are then inolosed by cover plates 7 lie against the backs of the disks 0 and 03, th
the pins. he cover plates may be secured in any suituse' of set 7 except for the =innerset in the bottom plate. If desired however,- they may all engage 1n, countersunk recesses in the backsoftheplates. The grooves atj-g p deep enough-to accommodate the pin-heads -'b so vthat they preventt-the pins. from being forced out backwardly in USO.
them and th cover plate need not be of any great thickness or weight, and for instance a plate of three-eighths of an inch to half an inch in thickness will be quite strong enough when pins with heads one-eighth of an inch thick he cover plate will usually be the disk on it fits, and may be than that above mentioned.
If pins a are used which are approxias hard as the metal of the disks 0 he pins and the sides of the holes in the disks will both be'compressed slightly e pins, and new pins when driven in subsequently to replace used, 1t may be necessary to fit sleeves or each time when the p1ns are renewed. Such bushes can be ese cover plates have groovesturned therein as at g, to accommodate the headsb of 'tlonary, or the disks rotate in-opposite directions.
If very hard pins are used in all cases if preferred. Fig. 3 shows ins an engaging in bushes i in the plate d.
The holes in the disks and the parts of the ins which engage therein may be slightly tapered in order to provide a wedging fit; the cover plates will then prevent the pins from being forced out during use. The taper would be so slight that it could not be shown clearly in the drawing.
The disks are shown as being grooved at y in concentric circles facing the ends of the pins' a of the opposing disk members, slight clearances being left in order to avoid any packing of-material which might injure the pins. The method of mounting the pins referred to above, secures the most accurate positioning of the pins combined with rigidity, and the clamping of the pin heads in grooves is an important feature in securing this result. 7
Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a rotary disintegrating, pulverizing or mixing apparatus, the combination with a pair of dished disks each having a plurality of concentric grooves in their adjacent faces, the grooves of one disk'alternating with the grooves in he other disk, and each disk having a plurality of holes formed in concentric circles and alternating with the grooves, the axes of the grooves and holes being parallel to the central axes of the disks, fixed bushes, for lining said holes, and flats formed on the rear faces of the disks around the ends of the holes, a plurality of hardened plain pins having en- Gopies of this patent may be obtained for or mixing apparatus,
five cents each, by addressing the Washington, D. G.
larged heads forced into said holes and arranged so that the pins in one disk face the concentric grooves in the other disks with a slight clearance between the ends of the pins and the grooves, cover plates for the rear faces of said disks provided with a plurality of concentric grooves of suflicient depth just to receive the pin heads and prevent axial movement of the pins, and means for securing the cover plates to the disks.
2. In a rotary disintegrating, pulverizing the combination with a pair of disks each having concentric grooves in their adjacent faces, the grooves of one disk alternating with the grooves in the other disk, and each disk having a plurality of holes formed in concentric circles and alternating with the grooves, the axes of the grooves and holes being parallel to the central axes of the disks, fixed bushes for lining said holes, a plurality of hardene plain pins having enlarged heads forced into said bushes and arranged so that the pins in one disk face the concentric grooves in the other disk with a slight clearance between the ends of the pins and the grooves, cover plates for the rear faces of said disks provided With a plurality of concentric grooves of sufficient depth just to receive the pin heads and prevent axial movement of the pins, and means for securing the cover plates to the disks.
