APPARATUS FOR FEEDING ENVELOPS.

Application filed January 12, 1907. Serial No- 352,006.

.To all whom it may concern:

Be it known that l, FREDERICK CYRIL JENKINS, a

subject of the-King of England, residing at The Grange,

Goldington, near Bedford, England, manufacturer, have invented a certain new and useful Apparatusfor Feeding Envelops to Addressing-Machines, of which the following is a full, clear, and exact description and for which I have applied for Letters Patent in Great Britain, dated December 12,1906, No. 28,371.

This invention has reference to an apparatus for feeding envelops to envelop-addressing machines. It consists of apparatus adapted to contain a number of envelops and capable of being fitted to such a machine, these envelops being attached to or picked up by a traveling band or apron which feeds them to the ad- Figure 1 shows in side elevation the apparatus and addressing machine, the former being in centralsec-- tion. Fig. 2 is a front elevation with a portion of the machine broken away so as to show clearly the platen and-band. Fig. 3 shows the ends of the band ready for connection together. Fig. 4 represents the same when joined. Fig. 5 is a view of a portion of the band. Fig.

6 shows the chute in which the envelops are placed.

Fig. 7 is a diagram showing a convex roller. j Fig. 8 shows a guide for the band so as to divert it from its line of travel and bring it towards the flap of the envelop.

The traveling band-or apron employed in this apparatus is shown consisting of asheet 1 of stontflexible material such as paper or linen provided with transverse slots 2 and gussets 3 forming pouches into which the flaps of the envelops enter so that the envelop is engaged by and carried along with the band. The, slot and gusset may be of any desiredshape, straight or 0therwise in theexa'mple illustrated the slot iscurved and the gusset ispf slightly larger extent so as to cover completely the ba -2 formed in theband by the slot. This arrangement possesses the advantage of facilitating the ultimate discharge or detachment of the 'envelop from the band. The free end of the gusset is at right angles Specification of Letters Patent.

to the edges of the band or to the line of travel of the band in order to secure correct alinement of the envelo'ps as they are presented to the striking face of the type. As a pocket approaches the flap of the envelop it bellies out, see Figs. 1 and 2, and consequently the tongue of the flap is with certainty engaged by the pocket. Prc ferably this band is of a width in excess of that of the envelops intended to be used therewith and the distance of the slots 2 apart is greater than the height or depth of the envelop of the maximum width proposed to be used upon the band. I

The band is shown joined at its ends so as to form a continuous apron or belt by means of the slots 4, 5 at each end which are interconnected by means of the flexible strip 6 of metal, xylonite or the like. Alternatively the ends of the bands may be pasted or similarly secured together. This band 1 is represented on the accompanying drawings (Fig. 1) as extending around the platen or cylinder 7 of the typewriting machine. The band l passes out from a frame work or structure Stile wheelbase 9 of which is mounted on wheels 10 so that the wheelbase and the frame supported thereby move in conformity with the longitudinal i'novements of the platen 7. The band is drawn from the apparatus 8, 9 by the revolution of the platen in the ordinary way, the usual clips or guides 35, 35 maintaining the band in frictional contact with the -writer are shown at 33, while 34 is the usual grip roller which holds the band and envelop against the platen- 'l. The ordinary sliding clips or stops which hbld the hand down upon the platen are represented at 35 in Figs. 1 and 2. The carriage 36 travels on the rails37 of the typewriter. The ribbon spool is shown at 38 the spool winder at 38 and the bell at 39. The frame 8 is shown comprising parallel end members 8 suitably braced and tied by means of the rods 11, 11; it carries rollers 12, 13 and 14 conveniently journaled or spindled at 40, 41 and 42 respectively in the end members 8 and the band passes around. these rollers in the direction indicated by the arrows. The

roller 12 is the lowest on in the frame and the band I extends thencegover the rolle'r l3 and after having been wound around'the platen 7 it is returned over Above the point where the'band rises from the roller 1 2, it passes close to a chute 15 wherein the envelops have been placed with their flaps towards said band.

The chiite is composed ofa hopper into which the envelops .16, 16.are' stacked and it is so inclined at for example 45 that the foremost envelop 16 falls against the traveling band 1 and its flap 16 is engaged by the pouch or pocket of the band. The band asit is drawn up from the roller 12 by the rotation of the platen sags at the gusset of the pouch and engages and lifts the envelop and conveys it over the roller 13 to the platen 7 of the typewriting machine. On this portion of its journey it passes over a lower runway shown here as a turtleback 17 which consists ,of an arched or curved surface mounted between the end members 8" of the frame. i

An upper runway also shown here as a turtleback 18 is similarly arranged between the members 8 and over this surface 18 the band 1 still carrying the'envelop 16 passeson its return from the top of the platen 7. The upper turtleback l8 extends ,.over the lower one in the direction of the typewriter being beveled or dropped at-its extremity 18 to facilitate the travel of the band and envelops. At its other end the turtlehack 18 projects beyond the roller 13 and up to the roller 14 being practically tangential thereto so as to lead the band to the said roller whence the band is shown dcscending almost vertically to the roller 12. The roller 13 is with advantage made of larger diameter than either of the rollers l2, 14 because when passing around this roller13 the envelop is on its front with the flap away from the roller. These three rollers 12, 13 and 14 may be cylindrical, convexed'or concave as may be desired; on the drawings they are shown cylindrical.

The end members 8 may extend upwardly above the turtleback 18 to a slight extent if so desired; in this way these extensions may, asshown at 19 for example, afford guides or flanges forfthe'turtleback 18 and may so prevent undesirable lateral movement of the band 1. p

It will be noted that whereas between the rollers 12 and 13 and the platen the envelope are upon the under side of the band 1, the latter after passing around the platen 7 is of course" inverted. with the result that when the band leaves the turtleback 18 in order to descend to the roller 12 as shown by the arrow the envelops are inverted and as soon as they are clear of the roller 14, that is to say when the flap is no longer held between the pocket gusset 3 or the band 1 and the roller 14,they will fall by their own weight, being jerked off if necessary by the advance of 'the band from the ,platen. In order,'however, to insure the detachment of the addressed envelop from the band 1 and in case the envelop should from anycause have become adherent thereto, I may provide a deflector plate 20 curvedoutwardly from the path of the band '1 and having a striking roller at its end nearestv the band 1. This plate is mounted. on a suitable" support as a bracketj22 riveted or otherwise aflixed to the frame of the machine 8. A hopper or other receiver may be arranged away from theband land outwardly below this deflector plate 20 in order to collect the envelope as they leave the band, but such collector is notshown on the drawings. i

In the arrangement illustrated'in Fig. 8 I have shown a spring-pressed roller'23 guiding the band 1 between the rollers 12 and 13 outwardly towards the flaps of the envelops. I The spring 24 presses the roller 23 in that direction in a yielding manner and this device insures the proper engagement of the flaps a guard plate '25 which ,also insures the guiding of the attachment 8.

wheel base 9, rollers 12, 13, 14 andturtlebacks 18, 19

is secured to the carriage of the typewriter in any convenient way. The rollers or wheels 10 running onthe table, desk or other support allow the attachment to travel longitudinally with the platen of the machine and in lorder that with a typewriter having a shift key in which the carriage is displaced in a direction at right angles to that of its longitudinal movement, the carriage may be able to shift without hindrance from the attachment, .1 connect the carriage or bed which carries the platen by means of hinged bars or connections such as 26, 26 with the end member 8 or other convenient portion of the The bars 26 are shown in the example illustrated, as pivoted at 27 to the end members 8 and atthe other end clipped to or sprung over a bar or guid'e'roll 28-mounted on'thc carriage. Other hinged connections between the attachment 8 and the carriage of the typewriter may be used as the equivalent of the one now described.

The chute for the stacked envelope and comprising a hopper 15 has a forward edge or fiange'29 against which the bottom or lowest part of the foremost envelop will hear. The lower part of'the. chute is of smaller. size than the upper so as to allow for the increased thickness of the stack of envelops at the top because of their flaps.
