Definitions

  • FRANK EL POWERS or SPEmGE'IELD, MASSACHUSETTS.
  • This invention consists of mechanism for receiving envelops or cards from a machine making them either in bunches previously counted or one by one until a bunch of predetermined count is formed, compressing each bunch to the desired thickness, banding the bunch and delivering it toa receiving station for further disposal as boxing vor sorting or for other desired purposes.
  • Important improvements embodying one object of myV invention consists of means for, taking a band of predetermined length with a design or ornament printed or placed thereon, locating this design or ornament in a position on the bunch of envelo s or cards t0 befbanded, so that .when the anding of the bunchis completed the design or ornament of the bandwill appear in the same place on all the bunches banded because of the same setting of the parts.
  • Means are also provided for adjusting all the arts to the different sizes of envelops or car s, or different thicknesses of bunches, or' different lengths of bands and different positions of the design or ornament thereon.
  • Another important improvement-embody ing a second object of the invention consists of thin blades or wires of suitable material at each of the four side edges or the two uppermost edges of the bunch of envelops or cards to-be banded around which the band is wrapped to the end that thick bunches of light material that would not offer resistance enough to the banding operation to be of uniformthickness when banded ma be in this manner banded to a uniform thickness.
  • Another improvement comprising a third object consists of the use of folding blades which wrap the bandl around the bunch of envelops or cards to a uniform thickness and in cooperation with the before mentioned blades or wires permit of a crease in any or all four edges of the band that would not be possible in the wrapping of a heavy band around a thick bunch of light material, the present method in putting up high grade stationery being to crease the bands by hand around a bloc of wood before banding. Because of the use of these blades or wires around which the band is wrapped, it is also possible for my machine to crease or even complete the folding and fastening together the band without the presence of an in-n i of closed bunch so that the band canbe taken ⁇ from the machine and the bunch inserted by hand or other means. When not needed for the purpose described these blades or wires can be removed and the band wrapped around the bunch without them, the other part being identical in operation.
  • this gum must be very quick drying and applied to the bands in a very thin even layer and my invention provides for that by my method of gumming as hereinafter described.
  • Another improvement consists in providing a means against which the ends of the bands can be pressed to x the gum so that this pressure will not be borne by a loose bunch of envelops which would not of itself permit of pressure enough to fix the gum or by freshly printed cards which would have ⁇ theink oHset by the pressure.
  • rI ⁇ his means provided to withstand the necessary pressure to fix the gum, therefore fills the dual function of fixing the to withstand the opening of the elastic bunch of envelops or to provide the necessary resistance to pressure when it is desirable to keep such pressure from the non-elastic bunch of cards.
  • the compression of an elastic bunch of envelops7 or the firmness of the material thereof is suliicient to withsta-nd the necessary pressure to 'fix the gum,

To all whom t may concern:
Be it known that I, FRANK B. POWERS, a citizen of the United States of America, residing at Springfield, in the county of'Hamp- ,den and State of Massachusetts, have invented new and useful Improvements in Banding Apparatus for Envelops,of which the following is a specification,
This invention consists of mechanism for receiving envelops or cards from a machine making them either in bunches previously counted or one by one until a bunch of predetermined count is formed, compressing each bunch to the desired thickness, banding the bunch and delivering it toa receiving station for further disposal as boxing vor sorting or for other desired purposes.
Important improvements embodying one object of myV invention consists of means for, taking a band of predetermined length with a design or ornament printed or placed thereon, locating this design or ornament in a position on the bunch of envelo s or cards t0 befbanded, so that .when the anding of the bunchis completed the design or ornament of the bandwill appear in the same place on all the bunches banded because of the same setting of the parts. The result is that perfect uniformity in the appearance of the different bunches is obtained. Means are also provided for adjusting all the arts to the different sizes of envelops or car s, or different thicknesses of bunches, or' different lengths of bands and different positions of the design or ornament thereon.
Another important improvement-embody ing a second object of the invention consists of thin blades or wires of suitable material at each of the four side edges or the two uppermost edges of the bunch of envelops or cards to-be banded around which the band is wrapped to the end that thick bunches of light material that would not offer resistance enough to the banding operation to be of uniformthickness when banded ma be in this manner banded to a uniform thickness.'
Another improvement comprising a third object consists of the use of folding blades which wrap the bandl around the bunch of envelops or cards to a uniform thickness and in cooperation with the before mentioned blades or wires permit of a crease in any or all four edges of the band that would not be possible in the wrapping of a heavy band around a thick bunch of light material, the present method in putting up high grade stationery being to crease the bands by hand around a bloc of wood before banding. Because of the use of these blades or wires around which the band is wrapped, it is also possible for my machine to crease or even complete the folding and fastening together the band without the presence of an in-n i of closed bunch so that the band canbe taken` from the machine and the bunch inserted by hand or other means. When not needed for the purpose described these blades or wires can be removed and the band wrapped around the bunch without them, the other part being identical in operation.
Other objects of the invention will appear in the following general and specific description thereof as well as in the annexed claims. In boxing what 'are known as commercial or oiicial envelops for the demands of' com- 75 merce it is customar to put one-fourth thousand or one-half t ousand in a box and in orderV that the envelops may lill the box and withstand transportation without arriving at their destination with ance of only partly filled boxes it is neces- .-sary to 'make-the individual envelops thick or fat enough to more than fill'the box without compression, the elasticity of the material Vallowing such compression in the process of bandin a box. My method of banding'provides` or such compression.
So-called commercial or oiicial envelops Vare now banded byhand with paper bands -held together lwith an adhesive material account of the elasticity called gum. On
of the bunches and their tendency to open `or separate the adhesive of the bands, this gum must be very quick drying and applied to the bands in a very thin even layer and my invention provides for that by my method of gumming as hereinafter described.
It has heretofore been the customto gum the ends of the bands and allow this'gum to dry before using the bands. This gummed v surface 1n present practice is moistened with water on a sponge just before using. This. makes a very quickly adhering process, and in my banding mechanism the bands can -be so provided with previously dried gum and 4105 the gum box orreceptacle for holding the gum as shown v1n my-mechanism can be filled with water, the distributing roller supplyin water to the gum linger instead of gum, an
the gum linger wetting the previously dried gummed surface of the bands, the operation of the parts being otherwise identical.
the appear- 80 Another improvement consists in providing a means against which the ends of the bands can be pressed to x the gum so that this pressure will not be borne by a loose bunch of envelops which would not of itself permit of pressure enough to fix the gum or by freshly printed cards which would have` theink oHset by the pressure.
rI`his means provided to withstand the necessary pressure to fix the gum, therefore fills the dual function of fixing the to withstand the opening of the elastic bunch of envelops or to provide the necessary resistance to pressure when it is desirable to keep such pressure from the non-elastic bunch of cards. When the compression of an elastic bunch of envelops7 or the firmness of the material thereof is suliicient to withsta-nd the necessary pressure to 'fix the gum,
`or when not necessary to keep such pressure from being applied directly to a non-elastic -bunch of cards, the presence of the means here provided is not necessary for the Iixing of the gum, but such means of providing resistance is necessary to meet all conditions Figure 1 represents an end elevation of,V

rihe operation of assembling the envelops will first be described. Referring to Fig. 2 the supporting frame work of the mechanism is indicated by D, the delivery mechanism of an envelop machine with a step by step operation is indicated by a. This mechanism delivers the envelops in a well known manner in a step by step operation. rl`he constantly reciprocating ejecting device a operates as indicated to push eachenvelop as it comes along to the delivery position into the assembling section A of the banding mechanism. As the envelops are passed into the assembling section the forward end of each one is prevented from falling by the" beveled face of the stationary device c. The envelop is thus caused to fall evenly to the 90 bottom of the envelop containing pocket. (See Fig. 5.) In .this manner a bunch of any desired number of envelops is obtained in the assembling section. During the assembling of these envelops in the bunch a 95 rod g reciprocated by cam 1 (see Fig. 3) driven in a suitable manner as from the envelop machine operates to pack the envelops assembled into proper form by means of the flat strips e whlch areV carried by the casting 10o d fastened to rod g, as indicated in Figs. 2
and 5. rlhere are two of these strips e operating to pack the envelops one against the other 1n the assembling section and lying between these two strips e is a very light spring wire f supported from the frame work in any suitable manner. This wire is at an angle to the movement of the envelops into the assembling section and it is so light and iexible that when an envelop strikes the me same it immediately rises but as the bunch of envelops is assembled this light wire resting on the top thereof gives just enough pressure to keep the envelops in proper posltion. After a desired number of envelops have 115 been assembled in a bunch the bunch is moved along the envelop containing pocket to a position in the banding section therein,v said position being indicated generally by B, Fig. 2.
The envelop containing pocket (see Fig. 4) is supported on the frame work and is open at the top and bottom with marginal ledges at the bottom on which are fastened hardened steel plates to support the en- 125 velops as they slide along the pocket. @ne side of the pocket 5 is adjustable horizontally on its supporting rods in a manner obvious from Fig. l to accommodate dierent widths of envelops. The stationary device c 1130 is adjustable in a slotl at the bottom of the pocket to different lengths envelops. As the assembled bunch is moved from the section.
A to the banding section B the spring pressed finger a. yields to let the bunch pass along the ocket.
Tie mechanism for moving the bunches from one section to another will now be de- Y scribed. A dove tailed horizontal plate 16 (see Fig. 1) is mounted below the path of the envelops and on this plate are mounted two quite similar sliding carriages g/ and n (Figs. 1 and 2). These carriages are limited in their sliding movements by the end stops t and i as they separate and by their abutting ends as they approach one another.
On the carriage n the gear la is mounted on a stud shaft and vertical racks 0 and o1 mesh ,with said gear. The rack o carries a horizontal slotted member m in which the vertical finger p is adjustably mounted. The
rack ol travels oppositely to rack o and is'V for counter balancing purposes only. The carriage n hasa pin vto coperate with the concentric slot Z of the gear. A spring j hasone end pivoted on the carriage n and the other end on the gear s. As the gear is turned for its slot l to have first one end against its limiting pin and then the other the spring j due to its specic mounting will pass across center and tend to hold the gear with slot Z havin one end or the other against its pin accor ing to the way the gea-r is moved to carry the spring'across center. This is all for the purpose to be described. The parts 3, o, u, 31 and 4 on carriage y correspond with parts le, o, o1, j and Z respectively of the carriage n and operate in the same manner as just described (with relation to the parts on the carriage n) when the gear 8 is moved. The rack 'v carries an adjustable slot member m1 similar to m on carriage n but m1 has adjustably mounted therein two vertical members 6 and 7. The carriages n and z/ are slid forward and backward by equivalent link members operated by differently designed cams. Referring' to Fig. 3 theV cam 12 suitably mounted and driven from the main cam shaft 71 as indicated-raises and lowers a roll 14. spring pressed on its face in a definite time relation. This roll 14 is mounted on a rack member 15 having a forked end embracing the axis of the cams 12 and 13, to
guide the rack member and a vertical slot embracing astud .5' on which a gear segment is mounted to mesh with the rack. As the rack moves it turns the segment which has attached thereto the link member -r (see Fig. '2). The latter is thus Aswung forward or baclnvard as the roll on the cam rises and falls. This motion is transmitted to the carriage n through the link g pivoted to gear c. .This movement of the carriage y is transmitted from cam 13 through link members 1 and 2, the former swinging on center s by mechanism similar in every way to that just described. When the bunch of envelops is properly assembled in the assembling section and ready to be transferred to the banding section the link member g has moved the sliding carriage n against stop i and as the link member g continues to move due to cam 12 the gear k is turned so that slot Zmoves to bear against its pin at the 'other end than is the case shown in Fig.. 2. The spring j meanwhile is moved across centers and the rack o moved vertically. The spring A tends to hold the parts in the position to which they have been moved for when the link member y moves to the left (Fig. 2) the frame n slides on the dove tailed plate 16 for spring j has sufficient force to keep gear c from turning as long as the frame n can slide but as soon as the end thereof abuts" from which it pushes the bunch of envelops into position for banding. As the finger p finishes its forward movement thefinger 6 carried by slide m1 has been moved by rack 'v of the carriage y into the full line position shown to jog the forward end of the bunch into proper position for banding. With the bunch of envelops in the middle position shown in- Fig. 5 the banding operations proper take place.
These banding operations Will now be described. They are diagrammatically illustrated in Figs. 6 to 10. It is desirable in many classes of work especially such as fine stationery to band the envelops in a loose elastic bunch of predetermined thickness. In this work the envelops, being made fat that is full and with considerable elasticity constantly tend to separate the ends of the bands and will separate them unless they are skilfully put' on and stuck together. In addition it is desirable in this class of Work to crease the-bands at the corners which show when the bunches are put in a box or to crease them at all four corners. The bands are now in practice creased by hand around a block of wood and then Wrapped around the bunch and stuck. It is important in the trade to get this clear cut appearance of the bands and applicants banding mechanism is adapted to givethis desired resultv in an automatic manner as well as to band all those classes of envelops or cards which do not need the refinement mentioned. To this end the bunch of en# velops when left in banding position are held between four creasing plates 72, 73, 74 and 75 as shown in Figs. 6 to 10. The plates 72 and 73 are extensions of the supporting plates of the envelop pocket while plates 74 and 75 are carried by a casting 78 held by a rod 81 in which it 1s vertically adjustable by a nut and slot arrangement (see Fig. 4) for dierent thicknesses of bunches. The rod 81 isy intermittently reciprocated by a cam 82 mounted on the main or cam shaft 71. (see Fig. 4) designed to give the necessary movements thereto. The
casting 7 8 has a slot in which side plate 74 is adjustable for different width envelops and carries a third plate 79 which together with plates 74 and 7 5 is` used to compress thev bunch to be banded to a predetermined thickness.
' Referring specifically to Fig. 4 the full and dotted lines of the folding and compression plates 74, 79 and 75 illustrate the cycle of operations of these plates. The bunch of envelops having been brought to position on plates 72 and 73 as described the.` cam 82 allows the compression plates 74, 79 and 75 to take the intermediate dotted line position. The bunch is thus compressed to a predetermined size for banding, every bunch of a run being treated in the same manner that is compressed and held compressed until the banding operation is completed. The predetermined length of band is thus wrapped around the predetermined thickness of bunch. When the banding operation is completed cam 82 allows the compression plates to descend to the lower dotted position in Fig. 4. (See also Fig. 10). This compresses the bunch when banded and allows the bunch and band to be readily transferred to the delivery section without having the band tear or bind as it leaves the folding plates. As soon as the bunch leaves the banding section and the band is free from the compression plates the envelops of the bunch expand to the limit which the band allows. Itis obvious that these plates 72 and 75 could be changed to wire fingers if desired.
Just before the bunch has been placed within the folding or creasing plates a swinging nipper arm 90 carries a band of predetermined length from a pile 92 of such bands (see Figs. 1 and 11) the band having been supplied with adhesive all of which will be described, and lays said band over the plates 74, 75 and 7 9 (see Figs. 1 and 6) after which the arm 90 swings back to an intermediate position all of which will be hereinafter described. With the band 4in place and the nipper arm 90 having returned as stated the band retaining members 76 and 77 are lowered to bear on the band. (See Figs. 7 and 10). rllfhe top bow in the band is thus straightened out and the band is held properlysfor the folding plates to operate thereon. These retaining members are carried by the cross arm 43 (see Fig. l) which latter is held on and moves with the vertical rod 40 in a way to be described. The member 7 6 is mounted in a slot on the cross bar 43 to be adjustable for different widths of envclops. With the bunch in the condition shown in Fig. 7 through the operations described the flat folding arms 104 and 105 operate.
The operation of the folding arms will now be described as illustrated diagram-- matically in Figs. 8 to 10. By lsuitable means to be described the arms descend parallel to the sides of the bunch (see Fig. 8) folding the band sharply as shown until the right angled extensions thereof are just at the lower edges of plates 72 and 73 as shown in Fig. 13. The vertical descending movement of the folding arms then stops and first one and then the other of said arms turning on centers vertically above the edges of the plate fold the ends of the bands around plates 72 and 73 (see Fig. 9) in overlap ing relation with the gum on one side stic ing against the other end of the band. Between where these two ends meet and the bunch a plate 10 fixed to the carriage y by upright 9 (see Figs. 2 and 5) gives a flat surface against which the sticking finger 110 presses the overlapping ends of the band.
rl`he folding arms 104 and 105 are mounted on studs 111 and 112 (see Fig. 13) carried by the cross arm 113 which latter is lixed to the hollow rod 34. The shaft 111 has an adjustable lateral connection (see Fig. 13) with the cross piece. A suitably coiled spring as 114 (see Fig. 2) is mounted on each stud to give each folding arm a constant tendency to swing inwardly. The folding arms are normally spread apart by arms 115 pinned to the studs 111 and 112 with rollers 116 and 117 at the opposite ends thereof bearing against either cam faces 118 or the upper ends of 31 and 32. rfhe normal position for the folding arms 104.and 105 is shown in Fig. 1 which also shows the lower position for the cam faces 31 and 32 which latter are carried adjustabl on a cross piece 30 fixed to the rod 29. ee Fig. 13). In
the folding operation there are five rods conl29 descend as do also the folding and'105. As soon as the rollers 117 on the arms 115 leave the stationary cam face 118 the springs on the studs 111 and 112 turn vcated in Fig. 9 almost as is hollow and rod 40 is positioned for move ment therein. Rod 40 is -are attached. The operations -of folding will n ow be specifically described. With the band 1n position as shown in Fig. 6 the cams i 26 and 55 either cause or allow through the five rodsmentioned the following operations: Cam faces 31 and 32 carried by rod the rollers 116 on the arms 115 into engagement with said cam faces. The cam faces and the folding rod descend to the position shown in Fig. '13 where they stop. During this movement the rod 29 having been lowered the pin 51 no longer' supports the rod" 40 at the upper end of the slot 52 and said rod falls by gravity until the band retaining lingers 76 and 77 rest on the band as indicated, As the rod 34 falls (see Fig. 2) an arm 192 attached thereto loosely pivoted" arm 191 turns and straightensthe band square against the ends of the envelop pocket 5. There are preferably two ofthe arms 191 and they are adjusted by device 190 to' stop at the desired4 point to square up different width bands. Slot 52 allows the pin 51 and rod 29 to move downwardly without moving the rod 40. Thus the band retaining .fingers will always descend into the band retaining, positionno matter what the thickness ofthe bunch of envelops may be. From the structure described itis seen'that the adjustment for the band retaining fingers lis lan automatic one. With the. folding arms 105 and 104 located as 'shown -in Fig. 13 'the rod' 29 .begins to ascend due-to its operating cam 26 while the foldingarms remain station .By an examination of the cam face-31 1n comparison with the cam face 32 itywill be these cams are raisedthe folding arm 105 will fold in the band due tothe spring 114 (Fig. 2) before the foldingfarm 104 operates as indicated in Fig. 9. This is due to the fact that the shoulder inthe cam face 31 l israised above roll 116 lbefore .the 'corresponding shoulder on cam face 32 is raised above roller115 of folding arm 104. As the cam faces continue to rise,
will fold .the other end of the band as indin Soon -as the first end 1s folded 1n. l The continued movement arms 104 falls and the seen that as l folding arm 104 of the cam faces 31 and-32 upwardly will l cause throu h the lower 45 cam surface (see Fig. 13 the'folding arms 104 and 105 to spread apart as indicated in Fig. 10. After the folding arms have been spread `apart the rod 34 due to its operating cam 55 on the main camshaft vbegins to rise. The folding arms 104 and 105 and the cam faces 31 and 32 al1 return to the normal position including the band retaining members carried by the rod 40. The cycle of operations just traced is best seen from a consideration of Figs. 6 to 10 in connection with the more detailed showing in Fi'gs. 1 to 13.
The specific means for operating the nipper arm 90 in order to carry a band from thepile of bands tothe position shown in Fig. 6 will now be described.
Referring to Figs. 11 and 12 the pile of bands 92 of predetermined length is located in a frame work as Ej The bottom of this frame work is gradually lifted as the bands are fed therefrom by a suitable rack and ratchety mechanism 170 operated from the.
main cam shaft 71. See Fig. 3). The nip- 4 per arm 90 is mounted on a shaft 130 and is operated through a segment 118 which has ,the connection as shown with the cam 199 located on the main cam shaft 71. This segment meshes with a gear 122 pinned to the shaft 130. On'thisshaft is a loose sleeve 124 `(see Fig. 12) to which is pinned the nipper arm ,90. This nipper arm carries a bar 120 having "a rack at each end thereof one turned 90 with respect to the other. One rack meshes with the gear 119 pinned to the shaft 130 and the other rack meshes with a gear 121 mounted on the nipper arm 90 and carryingthe movable nipper linger 102. The flexible spring 103 attached to the arm 90 limits-the movement, in one direction of finger 102. A friction device 125 tends to Vprevent the sleeve 124 from turning. `As the segment 118 turns the shaft 130, the gear 119 in mesh with the rack on bar 120 will move said rack if possible but if said rack is moved to one of its limiting positions and can move no farther, then the turning of gear 119 will operate to turn the nipper friction device 125. The nipper arm has the three positionsl shown in Fig. 11, the
normal position being shown infull lines and the two limiting positions being shown in dottedlinesf Ari-adjustable device 123 is mounted on the framework and has a hub fitting around the sleeve 124 with a lug to coperate with corresponding lug fixed with the hub of thefnipper arm90. These lugsy are shown dotted in Flg. 11. As the nipper arml 90 turns the lug on its hub, it i will coperate withthe adjustable lug held b y the device 123 whereby limltin posinous for the nipper arm 90 is 01011511.1051 es lso ` i incitera is indicated in dotted lines in Fig. 11. Withthe nipper arm in full line position shown in said figure, a gum carrying finger 128 operates to pick up the top band or label of the pile 92 and lift it until the label occupies a position directly againstv the inclined face of the gum boX 140 at which point the gum finger remains stationary. The-arm 127 carrying this finger has its center located atthe top of the bands so that as the top band is bent upwardly it swings on a true center and there is no tendency for the band to buckle or slip away from the gum finger. The movement of the arm 127 1s obtained through a link connection to the cam 201 on thel main cam shaft 71,arm 127 being pivoted at the point 202 which is on the level of the topmost band. The band is held in the raised position while the nipper arm 90 with the nipper fingers 101 and 102 as shown in Fig. 12 turns from the full line position shown to the lower dotted line position due to its cam and gear segment operating means.
The screw 126 then holds the band against the inclined face of the gum box and the nipper arm 90 can no longer turn counter clockwise. The cam operating said arm then causes the segment to turn the gear 190 in a clockwise direction causing the racks on bar 120 to operate gear 121 until the ni'pper arm 102 closes with 101 holding the band -back of, the gum portion therebetween. When the rack can no longer move due to the fact that the fingers are pressing together the continued movement of the gear 119 in a clockwise direction will operate to turn the nipper arm to the upper dotted line position carrying the band therewith and laying it across the folding blades as indicated in Fig. 6. As the nipper arm takes its upper dotted line position it is limited by the lug arrangement previously described from turning further in a clockwise direction.- The reverse movement of the gear 119 due to the cam and segment operating meansy willthen cause the bar 120 to operate the gear 121 and open the nipper fingers again to the 4position shown in Fig. 12. The spring 103 will thenstop the movement of the rack and the nippel` arm 90 mustthen turn counter clockwise against friction 125. This spring structure is necessary because of the y. desired adjustability of kthe parts for when the stop 126 holds the band against the gum box the continued movement of gear 119 presses finger 102 against spring 103 withouty any breaka e. of parts. After the fingers have release the band it is left in the position shown in Fig.4 7 and the nipper arm returns to the full line position shown in Fig. 11 and remains there while the .gum finger 128 picks up another band. As soon as the nipper arm takes the lower dotted position connection 180 (see Fig. 3) having a scraper 203 as indicated so that the upper surface of the roll will have a constant supply of guml which it transfers to the roll 129.
' When the gum finger is in line with said roll the cam 117 operates to lift the roll 129 into position to transfer the proper supply of gum to the gum finger. The latter then is turned on its center 202 to the position shown in full lines in Fig. 11. rThe gum on the finger will cause a ,band in pile 92 to stick thereto and as the arm 127 is raised the band will-travel with the arm. This gum is so placed on the end of the band that it is away from the edges thereof and there is no danger when the ends of the bands are stuck together that the gum will be squeezed over the edges.
The means for sticking the bands together and transferring the completed bunch of banded envelops from the banding position to the delivery position will now be described. Referring to F ig. 2' when the bunch the full line .position as shown in Fig. 11 the link motion 1 and 2 previously descrlbed operates to lower the fingers 7 and 6 in a manner similar to the movement of finger p in the carriage n Carriage y is then moved along to theright in Fig. 2 until it abuts the carriage n after which the fingers 7 andv 6 are raised in a manner already described until the linger 7 is immediately back of the pile of envelops which is then being banded. Carria e y also carries the plate 10 to a position indlcatedin Fig. 8 to aid in the sticking together of the ends of the band. After the folding vlingers fold the endsof the band around the bunch of envelops as indicated in Fig. 9fthe lingers 7 and 6 are raised tol a position in which the finger 7 is immediately back of the bunch of envelops then banded.. '-'At the same time the sticking linger 110 being raised with the :fingers 6 and 7 opera-tes to push the overlapping ends of the bands against the plate 10 as indicated in Fig. 10. Just'about this time cam 82 see Fig. 4) allows a spring or gravity to tion shown in Fig. 10-so that the band will not stick on said plates asthe bunch is transof carriagev n has moved and assembled the bunch from the assembling section to the banding section so that the linger 6 can Vjog up the front end of the bunch about to be banded in a manner already described. The carriage y then operates so that the fingers 7 and 6 and the sticking finger 110 are lowered into the position shown in Fig. 2 and the cycle of operations can be repeated.
In Fig. 9"l a modification of the means for sticking the overlapping bands together is shown. In this modication one overlapping end extends to the other end against one of the wrapping blades and as the wrapping plate folds the short end over against the underlying end the two are stuck together in the manner shown. In this modification the stickingfinger 110 and the plate against whichit presses is dispensed with.
With the banded b-unch of envelops on the plate 11 a cam 150 (see Fig. 1) through the link motion 20 and 22 operates to place the bunch 'of envelops on the slide 23. This latter slide is inclined as shown and leads to a delivery table where the bunches of envelops are delivered in a row for as each bundle slides down the table 23, that table is 'reciprocated by the means shown in Fig. 1
comprising a carriage arm connection with the link 152 operated from the crank wheel 24 in an obvious manner.
Referring to Fig. 3 the power for the machine is supplied from shaft s which is connected to the main cam shaft 71 through a suitable s eed changing gearing indicated generally y T. The cam ,shaft 71 can be turned by hand through the means indicated by R with the connection shown. Both from the drawings and descriptions thereof it can f be seen that the apparatus is made adjustable throughout as to the size of envelops or cards to be banded, the size of the bands used and the thickness of the bunch desired. A most convenient means of obtaining the desired adjustability of parts has been set forth for it will be .seen from Fig. v1 taken in connection withthe other figures thaty all the parts which need adjustment for the width of eni velops or cards have the adjustability provided at the right of said figure or -toward the front of the machine while all those parts which need adjustment for the thickness of the bunches have a top, up and down adjustment of the vertically moving parts I The different adjustments needed for the ldifferent lengths of envelops or cards are of,
course made lengthwise of the machine.
The lmeans here shown and described in the specific form of the invention described for compressing an elastic bunch of envelops are necessary for that operation, but it is obvious that the peculiar form of construction also allows the banding of a non-elastic bunch of cards, only the parts necessary to the latter operation being necessary to both.
While applicant has necessarily described a specific form of his invention the latter in its broad conception is capable of many specilic applications. ,The invention therefore is defined generically as well as specifically in the annexed claims. f
