ENVELOPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 491,935, dated February 14, 1893. Application filed May 13,1892. Serial 110,432,912. (N0 model.) Patented in England December 9, 1890, No. 20,096-

To all whom it may concern:

Be it known that I, JAMES BALL, avcitizen of the United States, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Envelope-Machines, (which in part has been patented to me in Great Britain, No. 20,096, dated December 9, 1890,) of which the following is a specification.

This invention, for improvements in envelope machines, particularly relates to'envelope machines comprising also printing mechanism, and having with relation to the folders a movable folding bed, or bottom, which is adapted to successively present fresh surfaces to receive the folding impact of the folding mechanism whereby any ink-impression imparted by the recently printed envelope face which at the time of folding is in contact with the portion of the folding bottom next to the folders, on the folding of the next envelope is carried away from the folding position in the machine.

The object of this invention is to so improve the construction of an envelope machine of the classindicated as to render it simpler, and more practical and efficient.

To these ends the invention embodies es sentially the combination with a movable ring and means for imparting thereto an intermittent movement, of folders which co-operate with the ring.

The invention furthermore consists in conjunctive devices having more or less intimate relations with said ring and folders and all as will be hereinafter fully described and set forth in the claims. g;

Reference is to be had to the accompanying drawings in which,

Figure 1 is substantially a plan view of an envelope making and printing machine, parts thereof,as the picker-operatin g mechanism, the platen for the printing mechanism, and the creasing box or frame,being understood as removed, such portions of the machine constituting no part of this invention,and hence their omission renders the illustrations given of increased clearness'. Fig. 2 is an elevation and vertical section centrally from front to rear of that part of the machine which com-- prises the invention. In said Fig. 2 the folderwings are indicated as in their swung up positions, and the ring as in its tipped down position, while in Fig. l the reverse relations are indicated. Fig. 3 is a vertical sectional View on an enlarged scale taken on the line 3-3,

part of the ring, the ring-support and an inter:

engaging device therefor as taken on the line 55, Fig. 1 or 2. Fig. 6 is a partial side elevation and sectional view on an enlarged scale especially showing the relations with the movable ring of the actuating pawl therefor the receptacle for delivering a cleansing liquid onto the ring and one of the wipers. Fig. 7 is a verticalsectional view of one of the wipers. Fig. 8 is a perspective View on an enlarged scale of a portion of the folding-ring (the same being shown as in its tipped down position) anda portion of the table adjacent thereto with the air chamber.

In the drawings A represents the table of the envelope machine the same having under the creasing frame, at, the curved recess a, there being mounted at said recess and in the usual arrangement relative to each other, the folder wings, the same being indicated at, b, and they, as well as their operating mechanism being as usual, are not here profusely illustrated and need not be described with further particularity.

B represents the ring which is mounted so as to have both an intermittent rotational movement, and a rocking movement, whereby fresh portions of the face of the ring may be successively brought to co-operative relations with the folders, and at intermediate periods have thesaid so-presented portions tipped down to insure or facilitate the discharge of the then folded envelopes. The ring Bis directly supported by and above the ring-formed support C, which 'is mounted for its rocking movement relative to the table by these meansz-The table near opposite edges, atits rear portion has the foot-pieces, c, bolted thereto which are provided with the out- Wardl y extended, axially aligned studs, cl; the sleeves, c, loosely surround said studs and have formed thereon,or rigidly affixed thereto, the depending brackets 6 which are of angular form, the inwardly extended horizontal member of each underlying the ring support, 0, and is bolted thereto. In Fig. 4: it will be noted that each sleeve, e, at its under portion is faced off to lie in bearing upon or in proximity to the top face of the folding ring, 13. The rocking movement is periodically imparted to the said ring-support so that the ring is first held in the plane coincident with the operating faces of the folders when in their folded down positions or retired downwardly from said position, through means of the connection therewith of the thrust-rod, f, which receives its reciprocatory movement from the cam f on the shaft, f which shaft receives its rotary motion in any of the usual manners common in machinery.

Z Z represent stop lugs, extended angularly from the circular ring-support at a portion thereof which is beneath the table, which serve to limit the rocking of the folding-ring and its support in its operative position.

The folding ring, 13, has its outer edge grooved as seen at g, and the ring-support, O, has angle-lugs, g bolted thereto which lugs have portions that lie respectively against the outer edge of the folder-ring, and enter the groove, g, all so that the folder-ring, while having its bodily movement as one with the ring-support, is restrained for its independent rotational movement without liability of displacement from its relations with the ring support.

The bottom of the folder-ring, toward its inner edge, has a continuous series of ratchet teeth, h, and 2' indicates a pawl which has its point or tooth in engagement with the ratcheted ring, and is so mounted that while its operative engagements with the ring will be maintained whether the ring is in its horizontal or tipped down position, it in no way interferes with the movements of the ring from the one to the other of the said positions. It will therefore be noted that said pawl is comprised as a portion of a comparatively long arm which is pivotally supported at the upper end of one arm of the angular lever, j, the other arm 3' of said lever being in operative proximity to the cam, on the rotary shaft, j. The springj maintains the angular lever always in working proximity to the cam. The pawl-ended arm, 2', has the weighted extension, 2' beyond its pivotal connection with the lever, j, whereby the pawl is held to its work,it being, of course, understood that ihe pawl has yielding movements to accord with the rocking of the ring.

Two pairs of wipers, 7c, are shown for the folding-ring, they being mounted to have bodily rocking movements in consonance with the ring and to have also movements independent of the ring always remaining in rubbing or wiping contact therewith. Each of the said wi ers comprises a spindle, having at its lower extremity a stirrup-like frame, 70 around the lower memberof which the strip of pad material, 70 may be wound, the terminals of said strip being disposed as seen in Fig. 7, between the upper and lower members of the stirrup-frame and confined by the wedge, 70.

Other specific forms of wipers may be substituted. Each pair of the said wipers is carried at the extremities of an intermediately pivoted bar or lever, m, which is journaled for a swinging movement on the upwardly extended boss, c of the aforementioned bracket-supporting sleeve, 6, and one of said two-armed levers has the arm, m, radially extended from adjacent its pivot, receiving the connection therewith by means of asuitable joint as seen at on, of a pitman rod, m which has its other end engaged with the crank or eccentric pin, m carried by the rotary shaft, n. A rotation of the shaft is imparted by the mesh with the gear wheel thereon, of the gear, 0, which is carried at the upper end of the shaft, 0 and has at its lower end a beveled gear wheel, 0 which meshes into the gear wheel, 0 on the shaft 7' The two double-armed levers, m, are united by thetie-rod m, so that the motion positively imparted to one of the levers will insure a corresponding movement of the other. The swinging orvibratory movement of the wipers is transversely of the direction of travel of the folding ring and is in addition to the said traveling movements of the ring so that by reason of the movements of the wipers and of the ring any portion of the face of the latter will be subject to the rubbing action of the former.

19 indicates a can for containing naphtha, or other suitable cleansingliquid, the said can being mounted on a bracket in proximity to and over the folding ring, and has a discharge cock p and also a vent at 12 all whereby the proper conditions may be established for the continuous issue of the liquid, drop by drop, upon the face of the folding ring. The liquid thus issuing from the can upon the ring is, as plain, carried as the latter moves, subject to the rubbing action of the wipers.

The air chamber is represented at D, located under the table next to the aforesaid curved recess, a, and has the air conduit, 1, leading thereinto from the air pump, D shown as mounted for an oscillatory movement near the bottom of the machine, and having its piston operating rod connected to one arm of the angular lever, 9",with the other arm of which the cam 0' has the working engagement. The air chamber has, through its forward wall, one or more air jets, it, so directed as to be thrown into the angle between the envelope back and the sealing flap as the latter comes below and in advance of said jets on the tipping down of the folding ring, and all as is most clearlyindicated in the drawings, Figs. 2 and 8. The

envelopes are thus caused to descend from their positions on the folder ring down into the drier chain.

' While I prefer to expel the envelopes from the ring by air jets substantially as described the invention is in nowise to be understood as thus limited, so far as the novelties in and otherwise relating to the folder ring are concerned becauseI may effect the discharge of the envelopes by reason of mechanical devices, entirely.
