Application filed November 28, mos. Serial No. 464,897.

pasting or gumming envelops, newspaper wrappers, orthe like andmore especially to means for applying paste, mucilage or the like whereby the use of adhesive material is so regulated as to insure even distribution over the sheet and whereby a large number of wrapping sheets or the like may be rapidly gummed.

The invention consists in. the matters hereinafter set forth, and more particularly pointed out in the appended claims. 1

In the drawings, Figure 1 is a view in perspective of a machine embodying features of the invention. Fig. 2 is a view in transverse section thereof, and Fig. 3 is a view in detail of an adjustable distributing late. i p Referring to the drawings, a base board or plate 1 is provided with a pair of paral-' lel u ri ht ides 2 of any preferred suitable des ign A trough 3 has at each end guide plates 4 which embrace the guides and allow the trough to be raised and lowered on the guides while maintaininglts horizontal position. The lower portlon oi the trough is contractedofr i-shaped 1n cross section and has a discharge neck with parallel walls extending from end to end of the trough; the rear wall 5 of this neck is fixed. The front wall 6 is provided with parallel slots 7 perpendicular to the lower edge of the wall.

permit the paste or other adhesive to go past it without lodging. w I

A gage plate 12 of hard rubber or the like with an upturned or flanged rear edge'13 rests on the base'between the guides 2 so A- distributing plate 8' is clamped against the inside .of the wall 6 as to be shiftable laterally, finger grooves 14 in the base plate 1 being formed to permit the ready lifting of the gage plate if desired. A removable division plate 15 may be inserted in the trough between suitable trough may be cut off to suit sheets of different widths.

upon the gage plate between the aides and below the reservoir or trough. I the sheets are not full width, the division plates are used to shorten the trough to correspond to them. The filled trough reservoir is low ered on the topsheet, and follows down the stack as the sheetsare withdrawn one by one. The serrated edge of thedistributing plate allows the paste to 'a'dherato the with drawn sheet in parallel ridges, and not be scraped off as would be the'case if the edge were straight. ,Byadjusting the distributing plate up or down so as to presswith greater or less degree of force against the sheets, a greater or less ampunt of paste may be applied to the sheet.

Obviously, changes in the details of construction may be madewithout departing from the spirit of the invention and I do not care to limit myself to any particular form or arrangement of parts.

'What 'I claim as my invention is l. A gumming machine comprising a base, a pair of upright guides thereon, a reservoir trough etween the guides having a V- sha ed bottom terminating in a dis'char nec with parallel walls guide plates on the ends of the trough engaging the guide? a plate on the inner side of the front wal of the neck having a serrated lower edge forming one lip of the outlet of the neck, thumb screws passing throu h vertical guide slots in the front wallof'the neck and clamping thesaid plate, and a gage plate remor/ably secured on the base below the reservoir.
