SPLIT SLEEVE LATCH Filed Nov. 3, 1960 INVENTOR T .E. 525-4- NORMAN E. DOVEY United States Patent 3,012,419 SPLIT SLEEVE LATCH Norman E. Dovey, 1922 Indiana Ave., Anderson, Ind. Filed Nov. 3, 1960, Ser. No. 67,055 9 Claims. (Cl. 64-6) This invention relates to a split sleeve latch and more particularly to an opposed movement latch to positively secure the two halves of a split ring around a driven shaft.
It has been common practive in cutting blanks from cardboard or analogous material to have the rotating knife seat against a rotating metal or rubber surfaced anvil composed of a split sleeve positioned on a rotating shaft in a printer slotter machine. The object of this invention is a latch mechanism that holds the two halves of the split sleeve anvil securely onto the printer slotter shaft. A further object of this invention is the use of a latch comprising two latching elements that operate in an opposite direction to easily secure the split sleeve anvil together and to conveniently allow separation of the anvil sections. One of the latch mechanisms produced according to this invention is used at each of the two joints of the split sleeve.
A further object of this invention is the use of a completely internal latch for securing the two sections of a split sleeve about a shaft by a latching mechanism that not only results in a substantial reduction of weight and cost of the sleeve assembly, but also allows a number of such assemblies to abut one another on a mounting shaft to form a continuous cutting surface that is not significantly broken at the junction between adjacent sleeves.
Still other objects and advantages of the invention will become apparent to a person familiar with the art to which the invention relates from the following description taken in connection with the accompanying drawings in which there is illustrated a preferred embodiment of the invention and in which:
FIGURE 1 is a plan view of two anvils mounted on a shaft;
FIGURE 2 is a partial cross section of the end view of the invention;
FIGURE 3 is a partial cross section of the assembled sleeve with the latch in the locked position; and
FIGURE 4 is a partial cross section of the assembled sleeve with the latch in the unlocked position.
Referring to the drawing, FIGURE 1 shows two split sleeve arbors 4 as they are assembled on shaft 2 which in this embodiment of the invention is the arbor shaft of a printer slot-ter machine used in cutting blanks from cardboard or like material at high speeds. It is noted that the arbors having the improved latch means may be placed side by side on the shaft 2. This feature is advantageous because the cutting surface may be increased by placing a number of the arbors together on the shaft. A split sleeve having an extended or non concealed latch mechanism could not be abutted to provide this continuous cutting surface.
In FIGURE 2 external surface of the sleeve 4 is covered with a hard rubber or like material to provide a cutting surface against which rotating knives of the printer slotter bear to sever whatever material is being processed. Generally, rectangular slots 34 and 36 are provided in sleeve half frames 6 and 8 respectively and these slots are positioned so that when the sleeve halves are brought together they form a continuous cavity 37. To mount the sleeve non rotatably on the shaft 2, a number of spaced keyways 12 are provided on the internal surface of the anvil. The keyways allow angular positioning of the anvil so that the knives will not contact the Patented Dec. 12, 1961 same portion of the cutting surface in successive installations. This allows even wear of the cutting surface. Relative rotational speed of the cutter shaft with respect to the anvil shaft 2 determines the optimum number of keyways 12. Anvil 4 is joined by two identical latching arrangements; one is seen in the cross sectional portion of FIGURE 2 and the other is at the opposite side and is represented by dotted lines.
In FIGURE 3 the two halves of the anvil are secured together. The latching mechanism at each side of the anvil 2 comprise a pair of clamping saddles 16 and 18 that have extending arms 38 provided with inclined camming surfaces facing inwardly. An operating bolt 14 has oppositely threaded portions that extend through apertures in saddles 16 and 18 so that rotation of the bolt causes the saddles to move in opposite directions. The two camming surfaces of the arms 38 on saddle 16 contact pins 20 and 22 respectively while in a like manner the two camming surfaces of the arms 38 on saddle 18 contact pins 24 and 26 respectively, so that the two halves of the arbor are cammed together. The pins 20, 22, 24, and 26 extend through cavity 37 and are received in the frame members through appropriate apertures.
In FIGURE 4 the anvil is disclosed with the latch mechanism in its unlocked position. The bolt 14 is rotated in a direction opposite to that required to lock the anvils and the saddles 16 and 18 are driven inwardly to disengage the camming surfaces of arms 38 from the pins 20, 22, 24, and 26. With the saddles in their disengaged position, it is possible to separate the halves of the anvil. To prevent the assembly of bolt 14 and saddles 16 and 18 from falling loosely from frame 8, a keeper 32 is provided in this frame. The recessed portions 28 and 30 of saddles 16 and 18 respectively engage the keeper and hold the beforementioned assembly within the slot 35 of frame 8.
To assemble the sleeve over a shaft the two halves are brought together around the shaft and the bolt 14 is rotated to move saddles 16 and 18 apart. This causes the saddles to engage pins 20, 22, 24, and 26 to securely fasten the sleeve into a unit and thereby hold it on the shaft. By reversing the rotation of bolt 14, the saddles are moved together and the sleeve may be separated and removed from the shaft.
Although the invention is described in the preferred embodiment of a cutting anvil for a printer slotter machine, the invention may be used in a variety of applications and it is not intended to limit this invention to the particular environment discussed.
