'oi'djfthat the blanks may" be entered between J Mountedabove-the table 4-is-asuitable frame- "the" rollers only atjthe, proper time, a 'stopin work 60 which-supports a-number of elements iis"providedfinthe"'form 'ofQa vertically recipdesigned v to secure the proper relationship of rbcatlng slide' mountd-infguides l2.an'dprovidthenblanks. One of these comprises-an;-angle- "e'dwithsidewi'se ekten'ding'pins l4 between which iron 62' to which are secured rubber or flexible" 5 M fiber members 64 most clearly illustrated in Fig. 5. These flexible members are capable of yielding in a direction towards the second pair of feed rollers so that a blank may move in that direction but if movement of a blank in the opposite direction tends to occur the members press downwardly and grip the same preventing such movement. As will be, clear, hereafter, this feature is of utility. inasmuch as the gauge 58 may be moving rearwardly beneath a blank. To prevent movement of the blank therewith the flexible cluding a table, means for cutting into sections members are provided. V

Pressers 66 are provided to hold the blanks upon the table 4. These members which are. beveled upwardly at their edges are carried by posts 68 secured in blocks 10 pivoted on horizontal rods 12. As will be obvious from Fig. 1, if a blank is moving towards the left in that figure thepressers 66 will readily rock upwardly to permit the blank to move therebelow. Brushes 14 of the type usually 7 used also tend to hold the blanks upon the table. To limit the inward movement of the blanks thereis provided a stop 16 adjustable along a rod 18 which is pivoted in the frame 68. An arm 88 I attached to its free end is connected by a pin and slot connection with the upper end of a lever 82 pivoted to the frame and arranged so that its downwardly extending end is engageable by a cam 84 incontact with which it is held by a spring 85. The object of this arrangement is to provide for raising of the stop out of the path of the moving gauge 58 so that the gauge may,

slide below the same without impact. Suitable adjustment of stop 16 along therod 18 provides for various sizes of blanks.

Directly beyond the rollers 24 and25 are feed.

rollers 88 designed to engage the incoming blank which is separated into a plurality of pieces and direct "thepieces into engagement with downwardly extending 'flngers 86 which project at [leading ends of the blanks beneath the pressers and brushes. The rollers 88 are driven through suitable. gearing 98 from the pulley 22.

I Fig.5 illustrates the original blank with the cut and crease lines thereon. The cut a is made by thecentral knives 26 and 2! on the rollers 24 and 25 while the cut b is made by the central knives 34 and 35 on rollers 32 and 33. While in the set-up disclosed only one series of central cutting knives is shown on rollers 24 and 25, it will beunderstood that a plurality of knives maybe used to divide the blank into several separate blanks which are fed together upon the table 4. If there are more than two blanks a suitable number of guides 66 may be provided and the stop 16 may be extended to take care of all of the various sections approaching it. Of course, a plurality of stopsmay be provided if desired. Similarly, the

cutting eifected by the rollers32 and '33 may take place so as to sub-divide the various sections into any desired number of finished blanks. Instead of forming merely four blanks, for example, sixteen or various intermediate numbers of blanks may be formed from a single .feed. i f ,fIn the operation of themachine, in view of the extended travel of the gauge 58; it must be such as to present the trailing blank to the rollers 32- and-33. The sections fed through the rollers 34 and35 and 88 will ordinarily pass over the gauge 58 as illustrated in Fig.- 5. As the gauge withdraws the members 64 prevent-the sections from moving therewith thus holding their edges together so following sections do not ride up and 1 over leading ones so that upon forward movement in the following claims.

What I claim and desire to protect by Letters Patent is:

'1.
