July 19, 1932. J, TOMLlN CUTTING MECHANISM FOR PRINTING MACHINE FOLDERS Filed July 10, 1951 Viz/02. .4

IN-YENTOR Patented July 19, 1932 UNITED STATES PATENT OFFICE" f FOHN R. TOMLIN, OF BROOKLYN, NEW YORK, ASSIGNOR TO B. HOE & 00., INCL, OF, NEW

YORK, N. Y., A CORPORATION OF NEW YORK 'i CUTTING MECHANISM FOR FRINTING MAGHINE FOLDERS' Application filed July 10, 1931. Serial'No. 549,374.

This invention relates to certain improvements in cutting blocks or rubbers for printing machine folders of that class in WlllCh a long and a short sheet are cut and as- 5 sembled.

In certain types of cutting mechanism used for this purpose, arotary cutter is used in which one of the cutting knives is mounted slightly less than 180 behind the other, so

that the knives or blades reach the cutting position at different points on the cooperating collecting and folding cylinder. Furthermore, these cutting blocks or rubbers are apt to fill up with paper strips or ribbons and other dirt, and this interferes with the cuttin operation.

I t is the especial object of the present invention to improve the construction of these cutting blocks or rubbers so that long and short sheets may be cut, and at the same time the blocks are self clearing of paper strips, dust, dirt or the like.

It is a further object of the invention to produce a block or rubber which is of few parts, and one that can be quickly and easily assembled and disassembled for repair or other purpose.

With these and other objects not specifically referred to in view, the invention consists in certain novel parts, arrangements and combinations which will be described in connection with the annexed drawing and the novel features pointed out in the claims hereunto appended.

In the drawing,

Figure 1 is a sectional view, partly broken away, showing a cutting cylinder and cooperatlng abutment shown in the form of a collecting cylinder embodying the invention; Figure 2 is a perspective View, partly broken away and partly in section, of one form of the improved cutting rubber or block;

Figure 3 is a broken side View and Figure 4 a cross section on line 4 of Figure 3 showing in detail one means of constructing and assembling the parts of the block;

Figure 5 is a broken side View and Figure 6 a sectional View on line 5 of Figure 5 showing a modification in the meansof constructis provided set at a little less than 180? beto relations.

As shown, the cutting cylinder is markedlandtis provided withcutt'ing knives or blades 2, one of which is shown, it being understood that another-cutting knife hind the first knife or blade. The cooperating abutment for the knife 2 is a collecting cylinder 3 provided with the usual sheet tak ing pins 4.

This collecting cylinder is provided with acutting block or rubber'of improved .con-

. struction which may embody'the invention in various forms, two of which'are shown. Referring first to Figures 1130 4;, this rubber is multi-part and includes a metal sheathing 5, 6, which is supported 011 shoulders 7 in a recess in the cylinder wall marked-8. Located in this recess are three sections, preferably of rubber, marked 9, 10 and 11,these being separated so that the cutting blade may pass between them, as indicated in Figure 1, the sections compressing the rubbers. It will be noted that with this construction the cutting blade enters deeply into the block so that it will cut a thick product, and at the sametime clears the blockof paper: strips, dirt and the like, as will nowbe explained.

The two outside rubbers 9 and 11 are cut away inwardly, as. indicated atlQ, to 'form spaced clearances through which paper blade, these'clearances connecting with vents V 18 in the cylinder wall, so that therubbish forced into the cylinder may readily be removed in any suitable manner.

Between the cut-out portions 12 of-the rubbers 9 and 11, there are left bosses 14, perforated as shown at 15, in Figure 4, which receive threaded pins 16 by which the parts of the block are assembled with and held in T position in the casing 1, before referred to, this form of construction being shown in Figure 2. In Figures 5 and 6, a modification of this construction is shown, in which instead of the bosses beingformed integral Iwhich. may be desirable u'ndercertain circumstances. Ashere shown, the sheathing block or box 7 in this modification encloses a pair of rubber blocks 19, 20, the lower adjacent faces of which are cut away, as indicated at 21, to form a recess into which the 7 cutting knife or blade forces any paper vstrips, dirt, etcz'This recess'communicates with a vent 22 through which this foreign material may pass inside the cylinder, and,

may be withdrawn as above described. The

plurality of resilient elements, the inner faces of which are recessed to provide a clearance through which paper strips, dirt and the like are forced by the cutting blade to clear the block.

5. In a cutting mechanism for paper making machines, a folding cylinder having a recess, a cutting block consisting of a plurality of resilient elements the inner faces of which are recessed to provide a clearance through which paper'strips and the like are forced by the cutting blade, and a vent in the cylinder wall and communicating with the recess between the resilient elements.

In testimony whereof, I have hereunto set -my hand. i

' V JOHN R. TOMLIN parts of the block maybe held together by the screw bolt 23. V 7

It will be seen from the foregoing that a simple but effective cutting block or rubber has been produced, one which can readily be assembled or dismantledfor repair or other reason, and one which isself clearing. lVhile the invention has been shown in its preferred forms, it will, be understood that certain changes in the structure shown and described may be made without departing from the invention as defined in the appended claims.

What I claim is:

1. In a cutting mechanism for printing l 1 machine folders, the combination of a cutter block composed of a plurality of adjacent resilient elements, the 7 two outer elements having inner recessed faces to provide clear ances through which paper strips, dirt, and

the like are forced by the cutting blade to 7 clear the block.

2. In a cutting mechanism for printing machine folders, the combination of a cutter block composed of a plurality of adjacent resilient elements, the two outer elements having their inner faces recessed at intervals With inwardly extending projections between the jcutouts and pins passing through the projections and holding the parts of the block in assembled position.

3. In a cutting mechanism for printing machine folders, the combination of a cutter-block composed of a plurality of adjacent resilient elements, the two' outer ele ments having their inner faces recessed at intervals to, form clearances, bushings be- 7 tween the intervals, and pins passing through the bushings and holding the parts of the block in assembled position.

- 4-. In a cutting-niechanismfor paper mak- 7 ing machines, a cutter block composed of a
