Moo mammina@ MACHINE IEOR` GUMMING AND PRINTING BNVELOPBS.

TO ALL WHOM IT MAY CONGERN:

Be it known that THOMAS V. WAYMOTH, of the city and county of New York, and State of New York, has invented a new and improved Machine for Guniming and` Printing Envelopes, and that the following is a full,

pnnying drawings, and to the letters of reference marked thereon, and'makiiigapar-t of this specification.

This invention relates to a machine designed more particularly for gumming' the sealilaps, so called, of the blanks `for envelopes, wrappers, aizfl other similar'articles, combined with suitable mechanism for separating the blanks from each other as they are gummed, and for taking the blanks after they are gnmincd, land carrying them away to dry, in such a manner that the gumined surfaces of the blanks will not lap upon and adhere toV each other while the gum is heilig dried. The blanks may also be printedwhile 4being -guinincd, if desired.

Figure 1 represents a plan or top "icw of such machine.

Figure 2 is alongitudinal vertical section :of the same, taken in the line z z, fig. 1, and looking in the direction of the arrow near that line.

Figure 3 is a. similar section in the same plane, looking in the opposite direction from tig, 2.

Figures 4, 5, 6, are detached views of various modifications of the movable friction-separator.

Similar letters of reference indicate like parts. A

A represents a frame, made of iron or any other suitable material of suilicient strength to form the bearings for the various working parts of the machine. The blanks to be gummed and printed, or gummed without printing, are supported by a table, B, which rests on two arms or lcgmrthat arellinged to the frame A so that the table can be raised up to a horizontal position, as shown in figs. 2 and 3, to support the blanks while being gummed, or gummed and printed, or can be turned or moved back from under thcpieker or gummer to an inclined position, to receive a fresh supply of blanks, whenever necessary, ,and withoutI stopping or interfering'with the motion of the picker or gommer. Such table is elevated or moved by a lever, b, which is pivoted to theframe A, and the inner end of which connects by a. link, c, with the table. When such lever and link are in line, as shown in iig. 3, they form a brace, which retains the table in its horizontal position, but by lifting or turning up the lever-b in the direction of the arrow marked opposite to it, in fig. 3, the table is made to swing or move buck so as to conveniently receive the blanks. Above the tableB, when in a horizontal position, rises the yoke C, to which a rising and falling motion is imparted by the action of cams d on the driving-shaft e, such cams being arranged so that they uct on roller-studsf, secured to levers g, which are pivoted at one end to the frame A, their other ends connecting with the guide-rods h of the yoke C. This yoke carries the gommer D, and also the type-case E, or, if desired, the type-case maybe connected to a separate yoke. The 'extent of movement of the yoke and gummcr is such that the gommer will descend quite to the surface of the table, so that a single blank can be gumuied. When a. pile or number of blanks is on the table, the gommer `is arrested in its descent by the blanks, and rests thereon, stopping short of its full motion. rlhe face of the gommer D is supplied with guru by means of a roller, i, the axle of which has its bearings in the ends of the gum-box j, and this box is secured to an arni, lc, which is hinged to a vertical arbor, V, to-which an oscillating motion is imparted by means. of a cam, m, acting on o. tappet, n, as shown in fig. 3. By the oscillating motion of the arbor V the roller t' is made to sweep across the face of the gommer D, whenever said gummer reaches its highest position, by the action of the cani d elevating the yoke C, and to cause the roller to transfer-the requisite supply of gum to the gumu mer, a revolving motion is imparted to such roller by extending its axle-beyond the arm c, so as to obtain room. for a small pulley, o. belt, p, stretched over said pulley, and over a pulley, q, on the driving-shaft',trans mits the desired motion from this last-named shaft to the gum-roller z'. This belt may be mode of Indiarubbor or other elastic material, whii-h will act as a springlto carry the arm K and gum-roller i back to their original position, as soon :is the cam m ceases tenet on the tappet 1t, or, if desired, a suitable tightening-roller may be applied to thc bolt p, so that the same will be enabled to accommodate itself` to the varying position ofthe pulley o on the axle of the gumroller z'. The arm k is provided with two legs or projections, r, which form the been ings for the ink-rollers s, which are intended to transfer the requisito quantity of printing ink to the types in the typwmgc E, This roller receives its supply of ink from.)a suitable ink-well, which is not shown in thc drawings.

In order to facilitate the operation of transferring the gum from the gummer to the blanks, and particu` larlv io facilitate the operation of printing, an elastic bed, t, made of thick India-rubber cloth or other suit muriel-inl, is lil-,iced on the table B, und-cr the pile of blanks, and this bed may be cut out to correspond shape of the blanks, or it may be made in any desirable form or shape. By the action ofthe gamine;A Y brought down upon the blanks by thc descent of tho yoke, and then carried up again, one blank after lnnoiso is'lifted oli' from the pile and delivered to the reciprocating carrier F, as hereafter described. of each bIankfrOm'the pile is facilitated by weak springs, u., which bear down on the curls of' such blanks, causing them toV be bent as the gummcr or picker raises them up, and n. perfect sepa-ration ofthe blanks onef'rom another is insuredby the movable separator G, which consists of a brush or ratchet-wheel mounted on a shaft. v; to which a Irapid revolving motion is imparted by the belt p, which also serves to impart motion to the guinroller or, instead of a brush or ratchet-wheel, an endless apron or belt may he employed, stretched over suitable pulleys, and which may be armed with suitable teeth or wings, Such separator moves in close proximity to the edges of the blanks, so that by its action, and the'action of the current of air created by its motion, the blanks are elfectually v'separated one from another, and 'only one blank at a time lifted from the pilcby the gummer, and delivered to the carrier. -The carrier F consists of a plattform, a', which is supported by two arms, b', extending from upright levers c, to which an oscillating motion is imparted by the combined action of the cams d', and a spring, e. Such arms b are supported and guided by grooved rollers, and' their motion is so timed that the carrier is made t-o pass under the gummer, and the blank picked up by it, as soon as the gommer has been raised enough to admit the same.

i The separation so that thecarrier may pass between the same and the pile of blanks on the table B. After the carrier has so passed under the gumzner and reached. its extreme position, it stops foi a short time and the gummer resumes its ascent, thereby bringing the blank in contact with or against the guard g', causing it to be disengaged from thevgummcr and drop down'upon the carrier. Such carrier is provided with two hooks, vh,which catch over the edge of' the blank oragainst which the edge of the blank rests, to prevent it-slipping o' the carrier. Immediately`ai`ter the blank has been so deposited'on the carrier, the latter moves back from under the glimmer, and carries the blank over and deposits it'upon the `endless api-dn H. The table' B may also be allowed to more with the pile of blanks from undef the gommer, after the latter has descended, so as to give more space for the At that point-the gummer stops, retaining the blank raised by it, V

movement of the carrier'. The endless apron H, which may be of a. single-piece of cloth, or a succession of tapes, or their equivalent, is stretched over two `rollers, i', which have their bearings in suitable boxes or standsrds secured to the frame A. On one of. these rollers is mounted a ratchet-wheehj, and i pawl, k', which engages with the teeth of said ratchet-wheel, and imparts to it and the roller to which it is fixed, and to the endless apron passing over such roller, an intermittent motion. Said pawl is pivoted to one of the levers g, which connect with the guide-rods of the yoke C, and to such pawl an intermittent motipn is imparted by the can: d, v(see iig.` 2,) er the requisite motion muy be imparted to it in any other suitable manner. This action of.

thel pawl upon the'ratchet-wheel, and the consequent intermittent movement of the endless apron, takes place` while another blank is being gummedand carried to and deposited on the endless apron. As thecarrier arrives at the back end of its stroke, over the inner ond of the endless apron, the edge of the blank resting on the same is caught between twopairs of pressure-rollers, k', situated above and below the apron in such a position that the same are caused to revolve by the action of the a said apron without fail. After the motion of theapron has been completed, a nger, c', descends andpresses pron, andlthus compel the blank to move along with' upon the blank just delivered, so las to prevent it being disturbed in its position by the next succeeding stroke. ot' the carrier. "A rising andfulling motion is imparted to such linger by the cambio/ed action of the spring m and cam d, which act 0n a double-armed lever, p', to one end of which the finger is connected as shown in iig. 3. The motion of the endless apron H is so regulated that the same travels a distance equal to the width on the gummed space of the blanks, after the delivery of each blank, so that the gummed 'surface of one blank will not be covered by or permitted to come in contact with the sulcceedin sticking together, and giving ample time to the gummcd'surface to dry.

By this machine the seal-flaps of the blanks for envelopes can be gummed in a simple, quick, and eiectivc manner; and simultaneously with the operation of applying the gum, any desired words or characters can be printed on the blank. The same machine can also be used with advantage for gnmming and printing the blanks of newspaper wrappers or of any similar article. v

What is claimed as the invention of the said THOMAS V. WAYMOTH, and is desired to be protected by Letters Patent, is-' i 1. The construction and operation of` the hinged table' B, substantially as and for the purposes set i'orth.

2. The operation of the movable separator G, or its equivalent, in combination with the glimmer D, subg blank, thus preventing suoli blanks stantially as and for the purposes set forth.

3. The combination of the gummer D and reciprocating carrier F, or its equivalent, and the endless apron H, or its equivalent, arranged und operatingrsubstantially as andi'or the purposes set 4forth.

4. Imparting an intermittent motion, by suitable mechanism, to the endless apron H, or its equivalent,

Vwhen combined with a reciprocating carrier, F, and gummer D, for the purpose set forth.

5. The operationlof' the rollers c,and finger l', separately or together, in combination with the endless apron H and carrier F, substantially as and for the purposes sct forth.

6. Gumming the seal-flap of .'.n envelope or similar blank by a. gummer which performs the double oice of gumming the blank and raising or holding it stationary, in combination with any suitable mechanism to receive the blanks, one after another, after they have been gumlned, and carry away such blanks, so gummed, in such a manner that the gummed portions will beiprevented from lying upon or overlapping each other While drying, for thc purpose set forth. i I
