ENVELOPE-MACHINE.
SPECIFICATION forming part of Letters Patent No. 299,814, dated June 3, 1884.
' Application-filed May 14, 1883. (Model) I set forth and described in the following specification, reference being had to the accompanying drawings.
My invention relates to envelopemachines; and it consists, first, in'a new organization of the machine, as hereinafter explained, whereby the envelopes are gummed after they are print- 7 ed, and thus the curling of the paper, due to the action of the gum while the envelope is operated upon, is avoided.
It further consists in the gumming apparatus,
' whereby the gummers are held out of contact with the plate.
In the accompanying drawings, Figurel is a front view of a part of an envelope-machine provided with my improvement. Fig. 2 is a longitudinal vertical section of the machine, some of the parts being shown in side elevation. Fig. 3 is a plan view of theinking-rolls and die. Fig. 4 is a perspective view of the gummers and tilting levers. Fig. 5 is an en larged detail view of the same.
A is the driving-shaft, on which is located a cam, a, for operating the slide which carries the printing form or die I). Also on said shaft is located an eccentric, c, from the strap of which extends an eccentric-rod, d, which at its upper end, connects with the arm 6, fixed rigidly on rock-shaft B, to give motion to said shaft B, and thereby furnishes a reciprocating motion to the armsf and g, which arms are connected to the cross-head h, which carries the ordinary hooks and devices for moving the blanks from the feeder to the printing mechanism, thence to the gummers, and finally to the folding mechanisms. On the shaft A is a cam, 1, whose office is to impart the required vertical reciprocating movement to the gumarranged the inking-cylinders Maud N--one on each side of the form-slide Sfor the purpose of giving a fresh supply of ink to the.
form-rollers w and as. By this arrangement of inking-cylinder I pass the roller over the form but once, instead of twice, before printing, and gather a fresh supply of ink alternately from each of the above-named cylinders M and N.
Iprovide one or more ink-fountains, 3 with the appendages thereto, as may be found necessary or desirable. As these fountains are identical in their construction, I will describe but one.
Attached to and in connection with fountain 3 is a frame having arms (l/(t, which carry a feed-roller, c. This feed-roller is kept pressed against the cylinder N, except as hereinafter stated, by the pressure of a spring, k, exerted upon the frame at the rear thereof. On the ink-cylinder N is a cam, d, which strikes a projection on the arm a and forces the roller 0 down against the pressure of the spring 70 upon the fountain-roller e,where it receives a supply of ink, being returned as soon as the cam passes the projection on the arm a by the spring is to its normal position against the cylinder N. On the arm a is a pawl, f which engages with ratchet g and rotates the fountain-roller e, on the shaft of which the ratchet-wheel is fixed.
Attached to plate Q, and in connection with gummers n n, are one or more tilting levers or stops, h,which swing on small pivots in such a manner that the passage of the blank under said gummers will swing them into a nearly horizontal position, as shown by dotted lines in Fig. 5, where they do not interfere with the descent of the gummers; but when there is no blank in position underneath the gummers the above-mentioned levers hang in avertical position and arrest the gummer in its descent just before the stroke is completed, thereby preventing the deposit of any gum on the plate which supports the blanks.
A cross -beani, I, is constructed with the usual form of platen on its under side, and of suitable strength to withstand the necessary pressure from the die or form in the act of printing or stamping.
S represents a slide operated by cam a, its upper end being arranged to receive any desired form or die for printing or stamping.
It will be seen by the above description of my invention that I print the blanks prior to their being either gummcd or folded. By doing this I overcome the very serious objection of having guni on the blanks when they are acted upon by the moving and printing mechamsm.
By means of the tilting levers I prevent the gunnners from descending the full length of stroke when there is no blank underneath, thereby preventing accidental deposit of gum 011 the plate which supports the blank.
Having thus described my invention, whatI claim is "1. In an envelope-machine, printing and gunnning mechanisms, combined with devices for moving the blanks from the printing to the gunnning mechanism, and with means, substantially as described, for imparting motion to the specified mechanisms, all substantially as described.
2. In combination with the vertically-reciprocating gummer and the plate for supporting the blanks to be gunnned, the tilting levers or stops adapted to be swung aside by the passage of theblank to the plate, and to limit the movement of the gummer when no blank is received by the plate, all substantially as described.
3. In combination with the gummers 01 01, one or more tilting lovers 7/, pivoted in the bed Q, and operating as and for the purpose Set forth.
