. providing, in lieu of a solid roll orroller to engage the overlying portions'or flaps of the sheet, a device for engaging the sheet the construct-ion shown, except in Figs. 6 and 7, this device is in the form ofa toothed wheel or star wheel, the teeth at their outer ends being quite a distance apart so that as one tooth passes out,
of contact with sheet there will timefbefore the the upper part of the folded be a very brief interval of succeeding tooth strikes it,
and this intermittent contactingof the device 7 its discharge plate 15, and, as it is carthe arms 38 and will be to more sharply fold the sheet alon wherethe presser bars with the paper will be sutlicient to allow the turned over sides, as the sheet is drawn along, to settle by almost imperceptible but rapid movements so that the entire portions of the overlying wings or flapsof the paper will so settle into place that the sheet as a whole will be drawn perfectly straight toward the delivery end of the machine and have its two folds sharply made along the lines of the crease imparted by the paper having been turned over the ed es of, the plate 15. Such properly folde sheet is shown in Fig. 5 and designated ,A. This intermittently-acting device referred to is indicated by 45,.and it is secured to a shaft 4.6 that lies across and over the machine near end, such cated over the large roll 22, around which the endless belt 20 asses. The shaft 46 is provided at one en with a pinion 47 that engages a gear, 4.8fast on the shaft 32 upon which is mounted the drum 22.
49 and 50 indicate a pair of rolls through which the folded sheet passes and which aict tie lines which have been already crease and pressed upon.
J The shaft 46 is'mounted in bearingsthat are secured to the free ends of arms 46*, the other ends of which arms are securely fas-' tened by screws, as shown in Fig. 1 or otherwise, to'the horizontal portions of the side bars 10. Through each arm 46*, near the said shaft bearings, passes a set-screw 46", the ends c-fwhich set-screws engage the side' bars 10 immediately beneath. By means of these screws the shaft can be adjusted higher or lower very slightly to regulate the degree of pressure with which the device 4:5 will bear upon the paper. Of course the adjustment can only be a slight one in view of the engagement of the pinion 47 on said shaft with the gear 48. I
In Figs. (5 and 7, I havesho'wn a modification in' the construction of the intermittently acting device that bears upon the upper portion of the folded sheet. In this construction I employ a solid roller 51. At the end of the shaft 46 opposite that which 'carries the pinion 47, I provide a slotted journal-bearing in which that end of the shaft 46 is mounted, and. tothe end of the said shaft .1 loosely secure an arm theothcr end of which arm engages a pin 54 placed cccentriczillyupon a pinion 55 that is, in mesh with n gear 56 on the projecting end of the shaft This mechanism will cause the roller 51 to intermittently engage the upper portion of the sheet and allow of the slight moving in of the folded over portions of the sheet so smooth and straight, the same as described for the other construction shown in the other figures. The bearing for the shaft 46 adjacent to the pinion 47 will necessarily have device .45 being loas-to lie perfectly shaft 46.
