ENVELOPE-IVIAKING MACHINE.
Original application led April 30, 1923, Serial No. 635,625, and in Great Britain October 17, 1922. Divided and this application filed .lune 25, 1924.
This invention relates principally to that class of envelope making machines described in British Letters Patent No. 3,231 of 1911 but it also is applicable to other classes of machines wherein an envelope blank is fed to and travels along with an endless band or bands and chain or chains, during which travel a gun'iming and folding of oppositely disposed fiaps is effected and the partly made envelope engages a wall and is then carried at right angles to the first direction of movement and during which latter movement the final gumming and folding is effected.
In machines as at present constructed, some of the partially made envelopes will get out of alignment, that is to say slightly twisted at the time they are delivered against the wall, whereby faulty shaped envelopes are formed and emerge at the delivery end of the machine. The object of this invention is to provide means whereby when a partially made envelope is delivered against a wall it will be properly positioned or be both properly positioned and momentarily held before it is carried away at a right angle to its first direction of movement for the final gumming and folding previous 'to delivery from the machine.
The means for properly positioning the partially made envelopes consists in a reciprocating clamp or stop which is actuated to arrest and hold the envelope at its forward edge the moment it reaches the Wall, `or a movable wall against which the forward edge of the envelope abuts and which rises to release the partially made envelope almost immediately, in order that the pins on the travellingbands or chains, which travel in the second direction of movement, may carry each partially made envelope correctly positioned for the final gumming and folding before leaving the machine.
The gripping or like appliance may be of any shape either to grip the partially made envelope or against which the partially made envelope engages, in which latter case the appliance is shaped to ensure that the partially made envelope is given its correct position.
This application is a division of application Ser. No. 635,625 filed April 30, 1923.
The invention will be described with reference to the annexed drawings in which- Figure 1 is a plan View of a portion of the Serial No. 722,860.
and part of the end portion being shown in section. v
Figure 3 is an end view of the portion of the machine shown'in Figure 1 and showing the appliances for stopping or arresting the partially made envelope.
Figure l is a perspective view of one form of stop or grip. i
Figure 5 is a perspective view of a form of stop suitable for arresting and positioning the partially made envelope.
Figure 6 is a diagrammatic view of a machine with the travelling or carrier appliances removed.
In the drawings only the part of the machine to which the invention is applied is shown, the travelling bands, chains, etc., boing fory the most part omitted for the salte of clearness, and the gumming and folding appliances being entirely omitted.
The partially formed envelope, at the end of its travel from the feed end A (Fig. 6) contacts with a wall or stop 23 as shown in Fig. 1.
In the case of ordinary machines and with ordinary envelopes the forward portion of the envelope which contacts with the wall or stop 23 is carried by a part of the bottom iiap and the rapidity of the movement will often cause the partly made envelope to swerve out of the position in which it should be in order to be carried at a right angle to its first direction of movement, resulting in the formation of an incorrectly shaped envelope, i. e., the bottom flap will not be properly gummed and folded. In order to obviate this, a clamping device is provided which consists of a clamp 24 carried by a rod 25 connected to a cross piece 26 carrying a rod 27 parallel with the rod 25. The cross piece 26 and rods 25 and 27 reciprocate vertically, and to this end the rods 25 and '27 pass through holes in a plate 28 supported above the wall or .stop 23 of the machine by a standard 29. The standard 29 extends through the plate 28, being .suitably secured to the latter, and .also through a hole in the cross piece 2G. The rod 27 carries a roller 30 Which contacts with a double cam Wheel 3l carried by a shaft 32. The shaft 32 carries a sprocket 33 driven by a chain 34 from any part of the machine, and a spring 36 mounted on the rod 27 has its opposite .ends bearing against a collar 35 adjustably secured to the rod 27 and against the plate 28, to hold the roller 30 in engagement with the cam Wheel 31.
The reciprocating action of the rod 25 and clamp 24 is timed With the feed so that the clamp 24 is lowered to grip or hold the partly made envelope just as the forward edge of the latter engages the Wall or stop 23. The clamp 24 thus prevents the partially formed envelope from altering its proper po sition, and the clamp 24 Will be immediately lifted in order that the usual stops 3T on the chains 33, 38 may engage the partly made envelope and carry it onto the gumming, folding and pressing appliances, as is usual, for completion of the envelope.
Instead of gripping or holding the partially made envelope with a plain grip .as shown in Figs. 1 and 2, the grip or holder 24 may be shaped as shown in Fig. 4 so as to grip it at two parts, or the holder may be shaped to conform to the forward edge of the envelope which contacts With the Wall and the partly made envelope may be arrested thereby, but in all cases the holder or arrester is reciprocated in the same manner as shown in Figs. 2 and 3.
As will be understood, the appliances shown are only examples of carrying the invention into effect, the novel features being the employment of reciprocating appliances which will properly position a partly made envelope at the end of its first path of movement and before it is caused to move in a path at a right angle to said first path.
What we do claim as our invention and desire to secure by Letters Patent, is tl. In an envelope-making machine wherein .an envelope blank is caused to move in one path in having an operation performed thereon and is then caused to move in a path at a right angle to said Iirst path in order to have another operation performed thereon and comprising means for conveying said blank in the latter path, a stop adapted to reciprocate into and out of position to engage the blank at the end of said first path of movement, and means for reciprocating said stop in timed relation to said conveying means.
2. In an envelope-making machine Wherein an envelope blank is caused to move in one path in having an operation performed thereon and is then caused to move in a path at a right angle to said first path in order to have another operation performed there on and comprising means for conveying said blank in the latter path, a Wall against which the partially formed envelope blank contacts at the end of its first path of movement, a vertical standard carried by said Wall, a plate fixed to said standard having a pair of vertical openings, a rod vertically movable in each of said openings, one on each side of said Wall, means connecting said rods, a stop carried by one of said rods to engage and properly position a partially formed envelope at the end of its first path of movement, spring means associated with said other rod and tending to move it in one direction, and means operable in timed relation to said conveying means for moving said last named rod in the opposite direction.
In testimony whereof We have hereunto Aset our hands.
