UNITED STATES PATENT OFFICE.
MATTHEW A. STEWART, OF NEWARK, NEW JERSEY, ASSIGNOR TO THE MATT STEWART COMPANY, OF MEMPHIS, TENNESSEE, A CORPORATION OF MAINE.
ENVELOP-MACHINE.
Specification of Letters Patent.
Patented June 28, 1910.
Application filed July 25, 1907'. Serial No. 385,524.
Be it known that I, MATTHEW A. STEWART, citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Envelop-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to manufacturing envelops from a previously formed strip, the functions of the machine being to fold the strip, divide it, gum and again fold, and de liver the envelops upon a carrier.
In the accompanying drawings, Figure 1 is.
a side elevation of the machine. Fig. 2 is an elevation looking from the right in Fig. 1. Fig. 3 is a similar view looking from the left. Fig. l shows that side of the machine opposite the side seen in Fig. 1. Fig. 5 is a vertical section in a plane substantially parallel to the sides seen in Figs. 1 and 4. Fig. 6 shows a portion of the formed-strip, or stock, used by the machine. Fig. 7 is a side view of a portion of a folding blade. Fig. 8 is a detail view of a feed-roller adjusting device. Fig. 9 is a detail view of a portion of paste apparatus. Fig. 10 is a section on the line 1010, Fig. 1. Fig. 11 is a section on the line 1111, Fig. i.
The machine is usually employed as an at tachment for strip forming and printing apparatus forming no part of the invention and hence is shown as supported by attaching bars seen only in dotted lines.
In the drawings, A, A represents a suitable frame and A a horizontal table fixed in the frame and having at its front side curved guides, C, adapted to fold inward the lateral wings of a continuous formed strip, D, 6) which has been properly scored for folding. This stock strip, on leaving the guides, passes between feed rollers, E, E, the upper of which is pressed down upon its companion by an adjustable spring E shown most clearly in Fig. 8, while the lower roller is intermittently rotated from a power shaft F, itself actuated in any desired manner, as by a gear F. The motion is transmitted from the shaft by an arm E fixed to or carried by the shaft, in position to strike, in each revolution, one of three roller studs E upon the face of a disk E borne by a stud E upon the frame, the disk being rigidly connected with a gear E which meshes with a pinion E upon the shaft of the feed roller. The roller studs are 120 in angular distance from each other, and it is obvious that each revolution of the shaft F turns the disk through one third of a revolution. The parts are so proportioned that this movement advances the stock strip through a distance equal to the length of an envelop blank.
' After each feeding movement, the strip is severed by a knife G secured to a slide G which moves in a way G and is normally held at its highest point by a spring G The slide is forced down at intervals by the pressure of the free end of a centrally pivoted lever, G forcibly swung upon its pivot by a cam G upon the shaft F acting through a link G connected with the outer end of the lever. The blank thus severed lies upon two slightly separated parallel rollers, H, nearly flush with the table and at right angles with the path of the strip, and at the proper time it is gummed, folded, and pushed down between the rollers by a blade H having at its lateral edges depending portions H projecting below the central portion of its edge. Above the rollers H are paste rollers I upon opposite sides of the path of the blade, one of them being mounted in pivoted links I and normally pressed against its neighbor by a spring I Alongside the other roller is fixed a paste receptacle I having in its bottom a delivery slot controlled by a wedge I which is ad justed at each end by thumb nuts I The paste escaping through the slot falls upon a curved slide I rigidly connected with the paste receptacle or as shown, integral therewith, conforming to the curvature of the roller I and so located that when moved horizontally toward or from the roller, the upper part of the passage between the two is correspondingly narrowed or widened. The slide is adjusted with respect to the roller by screws I rotating without advance in a fixed member and in threaded engagement with the slide. As the blade descends, it forces the paste rollers apart and receives from them paste upon the marginal portion of its body and upon the downward projections. The descent of the blade continues so far as to push the folded blank between a pair of rollers J, J, which carry it to another pair of rollers K, K and during this descent the lower margin of the body of the blade applies gum to the marginal portion, or sealing flap, of one side of the blank while the projecting portions of the fork like blade gum the end portions of the blank, which in this case have been previously folded inward. The four rollers are mounted in pivoted links J and those of each pair are yieldingly pressed together by the action of springs, J
One roller of each pair may be mounted in fixed bearings if desired, and one roller of the upper pair is centrally diminished so that as the folded blank passes only its pasted margins are pressed. One roller of each pair is hollow and receives steam or other heating agent through axial pipes, J*, in a well known manner. Two corresponding rollers of the two pairs are driven in the same direction by means of sprocket wheels L, L upon their shafts and a sprocket chain L from a sprocket wheel upon the shaft F. The shaft F also bears a pulley M which by means of a belt M and a pulley M drives an endless conveyer belt N upon which the completed envelops are delivered by the rollers K, K and by which they are carried away.
The stock strip D may be and usually is brought to the proper point for entering the guides C by passing it over idler rollers P and Q, borne, respectively, by adjustable arms 1? and Q fixed to the frame.
The folding and pasting blade moves in the manner already described in a suitable way in the frame and is raised therein by means of a rigid rack bar 0 secured to its upper edge and carried laterally outward and down alongside the frame A, where it is engaged by a segmental gear 0 pivoted to the frame and actuated by a cam 0 upon the shaft F, the cam acting through a link 0 to overcome the resistance of a strong spring 0* which tends to force the segment to swing downward. The link 0 is guided in its movements by a roller R, upon its rear face, running in a way on the frame A.
In order that the disk E may stop accurately at the end of each of its forward movements and remain fixed until it is again forced forward, I provide it with sockets in its inner face and at equal angular distances apart and mount in a recess in the frame A a non-rotating spring bolt T having a conical or rounded end to enter the recesses in succession as the disk rotates and hold the latter against accidental rotation and in exactly the proper position.
What I claim is:
1. In apparatus of the class described, the combination with means for folding inward the lateral portions of a stock strip and advancing the strip intermittently, of means for cutting envelop blanks from the end of the strip, a folding and pasting blade provided with lateral depending portions arranged to reciprocate across the path of the blanks, devices arranged to apply paste to one side of the blade as it approaches the blanks, and a pair of co-acting yielding rollers in position to receive the blade and blank as the former folds and pushes the latter from its initial position.
2. The combination with means for folding inward the lateral portions of a stock strip and intermittently advancing the latter, of means for cutting blanks from the end of the advanced strip, a folding and pasting blade arranged to reciprocate across the path of the blanks, a roller arranged to apply paste to the blade as it approaches the blanks, a pair of co-acting, yielding rollers in position to receive the advancing blade and blank, and a second pair of parallel rollers in position to engage the folded edge of the blank so advanced and prevent its return with the retreating blade.
