This invention relates to a machine for gumming and printing the blanks for envelopes, wrappers, and other similar articles.

The invention consists, first, in the employ ment or use of a hinged table, applied, in combination with the pickers or gummers, in such a manner that said table, or at least that portion thereof which supports the pile of blanks, can be turned out from under the pickers and brought in a convenient position to receive a fresh supply of blanks without stopping the motion of the pickers; second, in the use of an elastic bed composed of india-rubber or other suitable material, to be placed Linder the y pile of blanks on the table in such a manner that the operation of gumming, and particularly that of printing, the blanks is greatly facilitated third, in combining with the gumming mechanism a type-case secured to the same or to a different arm, with the gummers and suitable ink-rollers, in such a man-nerthat simultaneously, or nearly so, with the descent" of the gummers upon the pile of blanks the faces of the types are brought down upon the uppermost blank in the pile, and the operation of printing is effected without loss of time or eX- tra labor, fourth, in the use of a movable sep arator, applied, in combination with the gumming mechanism and with the pile of blanks to be acted upon by the gummers, in such a manner that by the action of said separator against the edges of the blanks, and by the current of air created by the motion of said separator, th'e gummers are prevented from raising morel than one blank at a time from the pile on the table, fifth, in the arrangement of an endless apron to which an intermittent feedmotion is imparted, in combination with a reciprocating carrier and with the gumming mechanism, in such a ina-nner that one blank after the other is rst taken up by the glimmer or gummers and then deposited on the carrier, and by said carrier it is brought 0n the apron, where the blanks arrange themselves in the proper order to allow7 the gum to dry without sticking to each other; sixth, in the arrangement of one or more rising-andfalling lingers, in combination with suitable pulleys and with the apron, which serves to carry off the blanks after they have been gummed and printed1 in such a manner that by the action of the linger or fingers and of the rollers the blanks are securely held on the apron, and as soon as the apron begins to move the iingers rise and the blanks are compelled to move with said apron, causingthem to arrange themselves in such a position in relation to each other that the gummed surface of each blank projects beyond the edge of the succeeding blank, leaving the gum free to dry and preventing the blanks from sticking together.

A represents a frame, made of iron orfany other suitable material of sufficient strength to form the bearings for the various working parts of my machine. The blanks to be gummed and printed are supported bya table, B, which rests on two arms or legs, a, that are hinged to the frame A, so that the table can be raised up to a horizontal position, as shown in Figs. 2 and 8, or that it can be turned back to an inclined position.

Said table is operated by a lever, I), which is pivoted to the frame A, and the inner end of which connects by a link, c, with the table. If

`the-lever and VVlink are in line, as shown in Fig.

2, they form a brace which retains the table in its horizontal position, but by turning the lever up in the direction of the arrow marked opposite to it in Fig. 3 the table is made to swing back.

Above the table B rises the yoke C, to which a rising-andifalling motion is imparted by the action of cams din the drivingshaft c, said cams being arranged so that they act on rollerstiids f, secured to levers g, which are pivoted at one end to the frame A, whereas their other ends connect with the guide-rods h of the yoke C. This yoke carries the picker or gummer D and also the type-case E; or, if desired, the type-case may be connected to a separate yoke. The face of the gummer is supplied with gum by means of a roller, t', the axle of which has its bearings in the ends of the guni-boxj, and this box is secured to an arm, k, which is keyed to a vertical arbor, l, to which an oscillating motion is imparted by means of a cam, m, acting on a tappet, n, as shown in Fig. 3.

By the oscillating motion ofthe arbor l the roller i is made to sweep across the face of the guminer whenever said gummer reaches its highest position, and in order to enable the roller to transfer the requisite supply of gum to the giiininer a revolving motion is imparted to it by extending its axle beyond the arm 7c, so as to obtain room for a small pulley, o. A belt, p, stretched over said pulley and over a pulley, q, on 'the driving-shaft, transmits the desired motion from this last-named shaft to the giim-roller t, and this belt may be made of india-rubber or other elastic material, which will act as a spring to carry the arm 7o and gum-box j back' to their original position as soon as the cam m ceases to act on the tappet a; or, if desired, a suitable tightening-roller maybe applied to the belt p, so that the same will be enabled to accommodate itself' to the varying position of the pulley 0 on the axle of the gum-roller i.

The arm k is provided with two lugs or projections, i", which form the bearings for the inkroller s, which is intended to transfer the requisite quantity of printiiig-ink to the types in the type-case E. This roller receives its supply of ink from a suitable ink-well, which is not shown in the drawings.

In order to facilitate the operation of transferrin g the gum from the gummer to the blanks, and particularly to facilitate the operation of printing, an elastic bed, t, made of thick indiarubber cloth or other suitable material, is placed on the table B, under the pile of blanks, and this bed may be cut out to correspond to the shape of the blanks, or it may be made in any other desirable form or shape.

By the action of the gummer one bla-nk after the other is lifted olf from the pile and delivered to the reciprocating carrier F.

The separation of each blank from the pile is facilitated by weak springs u, which bear down on the ends of said blanks, causing them to bend as the pickers raise them up, and a perfect separation of the blanks one from the other is insured by a movable separator, G. This separator consists of a brush or ratchet wheel mounted on a shaft, c, to which a rapid revolving motion is imparted by the belt p, which also serves to impart motion to the gumroller t; or, instead of a brush or ratchet wheel, an endless apron or belt may be einployed, which would be stretched over suitable pulleys, aiid which might be armed with suitable teeth or wings. Said separator moves in close proximity to the edges of the blanks, so that by its action and by the action of the current ot air created by its motion the blanks are effectually separated one from the other, and only one blank at a time is lifted from the pile and delivered to the carrier.

The carrier F consists of a platform, 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 cams d and a spring, e.

The arms b are supported and guided by grooved rollers f', and their motion is so timed that the carrier F is made to pass under the.

gummer as soon as the latter has been raised enough to admit the same. At that point the glimmer stops, retaining the blank raised by it, so that-the carrier can pass between the same and the pile of blanks on the table B, and after the carrier has reached its extreme position it stops for a short time, while the guminer reassiinies its ascent, thereby bringing the blank in contact with the guard g and causing it to disengage itself and to drop down on the carrier. Said carrier is provided with two hooks, 7L', which catch over the edge of the blank and prevent it slipping off from the carrier.

Immediately after the blank has been ile-- posited on it the carrier moves back from under the giiininer and deposits the blank on the endless apron H. This apron is stretched over two rollers, i', which have their bearings inv suitable boxes or standards secured to the frame A, and on one of these rollers is mounted a ratchet-wheel, j', and a pawl, 7c', which engages with the teeth of said ratchet-wheel and imparts to it and to the endless apron 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 which an oscillating motion is imparted by the action ot' the cam cl, (see Fi. 2,) or the requisite motion may be imparted to it in any other suita ble manner.

As the carrier arrives at the back end of its stroke over the inner end of the endless apron the edge of the blank resting on the same is caught between two pairs of pressing-rollers, k', situated above and below the apron in such a position that the same are compelled to revolve by the action of the apron, and that they compel the blank to move along with said apron without fail'. 1

After the motion of the apron has been completed a finger, l', descends and presses upon the blank just delivered, so as to prevent it from being disturbed in its position by the next succeeding stroke of the carrier.

A rising-and-falling motion is imparted to said linger by the combined action of a spring, m', and cam d', which act on a double-armed lever, p', to one end of which the linger is connected, as shown in Fig. 3.

The motion of the apron H is so regulated IAA that the same travels a distance equal to the Width of the gummed space on the blanks,

for envelopes can be gummed in a simple, quick, and elective manner, and simnltane ously with the operation of applying the gum any desired Words or characters can be printed on the blanks.

The same machine may also be used with advantage for gumming and printing the blanks of newspaperwrappers orfo' any other similar article.

What I claim as new, and desire to secure by Letters Patent, is-

1. The hinged table B, which swings ba and forth on arms a, to operate in combinati with the glimmer D, substantially as and l the purpose described.

2. The movable separator G, in combin tion with the glimmer D, substantially as ai for the purpose set forth.

3. The endless apron H, in combination Wil erating substantially as and for the purpos described.

4. Thelin ger l and rollers 7c', in combinatio; with the apron H and carrier F, constructei THOS. V. WAYMOTH. Witnesses z W. HAUFF, M. M. LiviNGsToN.
