ENVELOPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 446,124, dated February 10, 1891.

' Application filed January '7, 1890. Serial No. 336,208. (No model.)

To aZZ whom it may concern.-

Be it known that I, EMANUEL RAU, a citizen of the United States of America, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Envelope-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings making part thereof.

My invention relates to the operations of gumming, folding, and delivering the envelopes afterthe blanks have been cut and placed on the machine; and it consists in certain mechanism and combinations of mechanism fully hereinafter specified and claimed.

In order that persons skilled in the art may understand, construct, and use my invention, 1 will proceed to describe it, referring to the drawings, in which the same letters indicate like parts in the several figures.

Figure 1 is a top or plan view of my inven- Fig. 2 is an elevation from the end where the paste-boxes are located. Fig. 3 is a vertical longitudinal section of my machine on line X Y of Figs. 1 and 2. Fig. 4 is a longitudinal vertical central section on line Z Z of Figs'l and 2. Fig. 5 is a vertical longitudinal central section of the gum-transferring rolls and operating mechanism, in part, drawn to a larger scale. Fig. 6 is a side elevation of a portion of the delivery mechanism on a larger scale. Fig. 7 is an enlarged detail view of the tipping foundation-plate mechanism. Fig. 8 is a detail side elevation of the mechanism for sustaining and feeding the envelopeblanks upward to the gumtransferring rolls above. Fig. 9 is another detail side elevation of the tilting foundationplate. Fig. 10 is a top or plan view of the foundation-plate in its horizontal position. Fig. 11 is a central cross-section of the foundation-plate, Fig. 10; Fig. 12 is a cross-section of the foundation-plate and bedrplate of the machine, showing the clasps in elevation out of the way of the envelope to be folded. Fig. 13 is a front View of one of the connect- 7 ing-links, and Fig. 14 is a top view of the same.

A is the frame of the machine. B is the horizontal table or top plate of the frame.

A is a yoke which projects above the table and guides the folding-plunger.

O is the main driving-shaft.

O is a cam on the main shaft for operating the rack.

O is a reciprocating rack located on the top of the table B.

O is a cam-roll.

C is a forked rod which straddles at its I O to the table-frame A. The arm C is pivotally joined to the bell-crank lever O bya in C is the forked portion of the upper arm of bell-crank O It straddles a pin 0 ,10- cated on a downwardly-projecting lug attached to the rack O By these operating connections the rack O is reciprocated horizontally when the shaft O is revolved, and it is limited in its motions bv the shape of the cam O. A spring (3 aids in keeping camroll O in contact with cam O.

C is the hearing which supports pin O on the frame A.

On the opposite end of shaftO cam D is 10- pivoted by a pin D to an arm D keyed to a 1 shaft D, which runs across the machine. Arms D are keyed to shaft D inside its supporting-bearings D These bearings D are supported above the frame and table of the machine by brackets D, Fig. 2. 7

At the lower ends of arms D the roll D is carried and controlled in its forward and back motions. The roll D is a pasting or gumming roll. At its central portion it is provided or constructed with a raised portion D partially around its circumference and shaped to conform to the shape of the line of gum to be transferred to the envelope-blank. The lower ends of arm D are forked and straddle the ends of the shaft D which runs through the roll D and extends each end beyond the roll for this purpose. A gear-wheel D on the end of roll D meshes into and rests upon the toothed rack 0 so as to be revolved by the rack when the rack reciprocates. Longitudinal linksD located oneach side of the machine-table, receive the ends of the shaft D and guide its reciprocating motions. Thus when the shaft 0 is revolved the roll D is, through the operating mechanism, moved forward and back from one extreme limit of motion (shownin Figs 3,4, and 1) to the other extreme limit. v

A roll D is connected by the links D on on each side with roll D and has the same motions as D It also meshes into and is revolved by rack C The ends of its central shaft project and are guided in the forward and back movements in the side grooves DP. It is also a gumming-roll, and has similar construction in every way with D".

E and E are gum-boxes containing gum in a dissolved state. In one gum-box E rolls'E and E and in gum-box E a roll E revolve in bearings by means of belt-connections and intermediate pulleys with the main shaft, which will be hereinafter explained and indicated.

- E are rolls which revolve alternately in contact with gum-rolls E and D and E and D respectively. They are supported in bearings E, which bearings are attached to the gumboxes E and E by long arms pivotally, so that they swing to and fro when forced to do so. Springs E hold these swinging rolls in contact with rolls E They are thrown into con- 7 tact with rolls D and D when D and D are moved forward so as to strike arms E, which hang down from and are attached to the pivotedarms'E Thusthegumming-rollsD and D receive gum.

The gum-boxes E and E are supported above the frame-table on cross-brackets E, secured at each end to the table B.

Beneath the opening in the table 13 a pile of envelope-blanks F is supported on atable E, which is supported by upright rods F to which this table F is secured. These rods pass at their upper ends through guides F in the table B at each side of the machine. At their bottom they pass through guides and are connected to a bar E, which is drawn upward by a spring F attached to the frame A and the bar F Brake-shoes F fit these rods on one side,which shoes are intermittently moved away and against the rods F by means of the double lever F secured on a rod F which I runs from side to side across the machine and F are pendent guides on the under side of table B, which keep the position.

A vertical plunger-rod H has a guide-bearing at the top in yoke A at H and lower down at H At its bottom it has a plate for pressing the gummed envelope -blanks' into the usual folding-box beneath. H. The plate 11 and its rod H are reciprocated up and down at the proper times by link-connections H pivoted to the bar H and to the lever II. The other end of H is jointed to a lug H on yoke A and is supported at one'end by saidlug midway between the rod H and its jointed bearing in IT". A rod 11*, which passes down to shaft 0 at its lower end, has a forked extension H, which straddles said shaft. It also at its bottom supports a cam-roll H which, with the rod H rests upon and is operated up and down by a cam Hi Fig. 2, on shaft 0. It is kept in its contact envelope-blanks in with said cam by the weight of the parts; but

a spring may be added in case of need. Thus through the parts designated the folding plunger rises and falls as required, the cam is set to give the proper time to the operation, and the timing of all the operations of the machine is regulated by the position of the various cams on the shaft 0.

, Directly beneath the folding-plunger is a folding-box above the table B. The bottom of this box is a tipping foundation-plate I,

which rises and falls and tips to discharge the envelopes by mechanism driven from the main shaft C. It has two lugs I, which project downward, as seen at Fig. 11. passes through holes in these lugs I, by which the plate I is attached to a plate 1 from which correspondinglugs I extend upwardly. Shaft I also passes through theselugs. Thus plates I and l are pivotallyjoined. Beneath the plate 1 from each end, rods I run down and converge together at 1 Fig. 2, near the transverse center of the machine, and are subtended by a forked piece 1 which sustains a cam-roll 1 on a cam 1 on shaft 0. The piece I straddles the shaft C, like the other cam attachments. On the under side of table B, on the outer sides of the rods 1 subtend brackets 1 and they are joined to the table 13 by forked arms I togive rigidity. These brackets I are grooved longitudinally, and feathers I on rods 1 run in these grooves to direct their upward and downward movements and give them steadiness of motion.

Beneath the table B, situated at the ends of the tipping plate I, depend bracket-plates 1 provided with face cam-grooves 1 From the under side of foundation-plate I, at its sides, an arm I is secured, which extends across the vibrating center I of the plate, and by a pin and cam-roll 1 the plate'I is tilted over, as shown in Fig. 9 in full lines when the pin I is in its extreme downward throw, by the operation of the cam mechanism connected therewith, and when the pinl is in its ex- This plate is A shaft I 'ing the envelope until by tipping the plate I the clasps come in contact with the trippingpieces I which are bolted to the frame A,

and thus release the clasps and allow the envelopeto drop off the plate. These cla ps I are-secured to a shaft I on each end of the plate I and work together, so that when one clasp is struck by the tripping-piece I the clasp at the other end of the rod 1 also works with it. When the envelope is being folded by the plunger H the clasps I are thrown back out of the path-of the envelope by the clasps coming in contact with the bedplate of the machine, as shown in Fig. 12, and when the plunger retreats the springs I press the clasps I over onto the envelope and hold it firmly until the tipping of the plate I causes them to relax their hold, a above explained. The usual drying-carrier K, placed beneath the folding-box and tipping plate I, receives the envelopes and carries them a distance to dry them and returns them into the receptacle K. A hinged piece K receives the dried envelope and pushes it forward into the re-I ceptacle K to pack the envelopes together. This hinged back or packing-piece K is operated back and forth by a pivoted double lever K one end of which bears against the hinged piece K and the other rests on the arms 1 so that it is vibrated back and forth at the proper times by the movements of the tilting mechanism. A spring K aids in keep: ing the hinged piece K against the double lever K This lever K works on and is supported by a rod K, which has bearings in the frame A at its ends. The drying-carrier K is driven from the main shaft 0 and is of the usual construction. Longitudinal strips or plates Lare supported above the table B, under the plunger H, and over the foundationplate I by standards L. Plates L extend or run crosswise between these plates L and are attached to them, leaving an opening formed by their inner sides or edges of the size and shape of the folded envelope and conforming to the shape of the folding-plunger H. The cross-plates L are flanged to give a proper side surface for proper folding of the blanks.

On the edges of plates L are longitudinal guide-cleats, in which a carrienplate M moves forward and back on the top of the plates L. This carrier-plate has an opening through it of the shape and size of the folding-plunger or folded envelope-blank. It is moved forward and backward by lever M, which connects with said plate by a link M The lever l\ divides into two branches 1 3 and is keyed to a cross-shaft M at its lower end, which shaft has end bearings in the frame A. A lever h 5 is keyed to the shaft M" and extends over a lifting-cam on main shaft 0, which raises and lowers said lever and gives reciprocatory motion through the connecting-levers to the carrier table or plate M at the proper times to bring an envelope-blank under theplunger H, and over the folding-box opening aforesaid on this carrier-plate M, at its forward end, are lugs M, which catch the envelope-blank as the delivery mechanism throws it over them in the extreme forward throw of the carrierplate and carries said blank to and under the folding-plunger and opening to be folded and dropped by the tipping foundation-plate.

The folders N,being of the usual construction, location, and operation, need not be here described. Horizontal guard-wires O, secured above plates L to back-stop 0', direct the envelope-blank over its upper surface onto the carrier-plate. The inclined plates P, secured to and located between plates L at their rear ends, receive the envelope-blanks in trcmst'm to the carrier-plate M and guide its movements from beneath.

Q and Q are grooved pulleys supported on table B on bracket-bearings. Over these pulleysa belt passes and drives the gum-rolls E in their respective gum-boxes E and E. The shaft Q is driven by belt-connection to the shaft C below it over chain-pulley Q On the inn erend of shaftQ is a small groovepulley Q and near it, supported in a bearing on the table B, is an idler-pulley Q. A belt Q passes around Q and under Q thence up over loose pulleys on shaft D and down over a groove-pulley on cross-shaft Q pendent from the shaft D by arms Q and keyed to shaft D, and thence back again to pulley Q This belt thus revolves shaft Q A pulley Q is located 011 shaft Q Near its center, longitudinally around this pulley, a small cord passes to and around a loose pulley D on shaft D between the two gumming-surfaces on roll D out of the way of the gumming-surface, so that thecord receives no gum upon it.

From shaft D an arm Q hangs,which supports at its lower end a small pulley Q ,which rests upon the cord Q as a take-up or tightener. From the lower part of arm D hangs an arm Q which carries at its lower end a small roller Q. It also comes in contact with the cord Q but on its inner side, between this cord, which travels forward, and the roller Q the gumming-roll D delivers the envelope-blank after it. is gummed, as shown in Fig. 5. The revolution of the roller Q and the travel of the cord Q carry the blank onto the carrier-plate M, guided by the guards O and P above and below and by guards Fig. 3, sidewise attached to arm Q". A spring Q", wound around the shaft D, presses the arm Q and its pulley onto cord Q Operation: The operation of the various parts is as follows: Envelope-blanks cut to the required shape are placed upon table F and pressed upward to the level of the under surface of the gumming-rolls D and D by means of spring F guided by rods F and held firmly in position by brake F. The positions of the various parts are shown in Figs. 1, 2, 3, and 4, which show the gumming-rolls D and D in contact with the swinging gumtransferring rolls E ready to be revolved and to receive gum. By the revolution of the shaft C and cam 0-, through the intermediate mechanism before described, rack O is thrown backward and forward and revolves the rolls D and D in contact with the gum-transferring rolls These gum-transferring rolls have been thrown into contact by means of the pendent arms E struck and moved by the forward motion of the rolls D and D to their extreme backward limit. tion of the rack 0 in Fig. 5 indicates the gum- The gum-transferring rolls have previously received gum from the gum-rolls E and E,

ming-rolls D and D as having moved partially forward and in the act of picking up and delivering the gummed blank to the cord: and pulley,which moves it onto the carrier M.

The continued forward movement of the rolls D and D brings them to their extreme forward movement ready to receive gum from the distributing-rolls. The further revolution of the shaft C throws the rack C backward and forward and revolves the rolls D and D in contact with the distributingrolls. After the rolls D and D have received gum they imprint it on the edges of the blank which are to be gummed, and at the forward movement of roll D pick up the blank and deliver it to the'pulley Q over its upper surface, between it and thetraveling cord Q which carries it onward to the carrier M, which has by the revolution of the shaft and through the carrier mechanism before described been moved forward to its extreme limit of motion ready to receive the blank thus gummed. The blank by means of the cord and pulley aforesaid is delivered to the carrier over the retaining-lugs M. The carrier M is then moved backward to i s extreme limit of motion, which carries the blank under the folding-plunger II. This having been done, by a further revolution of shaft 0 the rolls D and D are moved forward over the rack C until they come into the position shown in Figs. 1, 2, 3, and at, as previously described, ready to perform the same operation again. \Vhile the gum is being applied to the blanks the brake F is released from These gumming-rolls D the plate L and onto the foundation-plate I. The plunger then rises to the position shown in Fig. 3. Immediately the folders N, operated by mechanism from shaft 0 in the usual way, fold the envelope-flaps onto each other and stick them together, leaving one flap unstuck and but partially folded over. By the revolution of the shaft 0 and through the mechanism before described the foundationplate then descends, and in doing so the plate is tipped over and discharges the envelope into the usual drying system K beneath. The envelope is then carried a distance and then returned into the receptacle K, and is moved forward in receptacle K by the levers K and K and the hinged back piece K as has been previously described. All of these various operations have been accomplished during one revolution of the shaft (3. The various cams and mechanisms have been set, timed, and arranged to perform their work in succession, as described.
