'T'YIE-WRITING MACH NE.

, To. all whom it may concern;

Be it known th t we, J OHN C. DOANE and .BENJAMIN H. SELF, both citizens of the and residing inthe city of Connecticut, have invented certain new and "useful. Improvements in Type-Writing Machines, of which the following is a specification.

This invention relates'to feeding envelops I to the pressure rolls or printing devices of typewriters and othermachines, and also to port a yieldingly while a is being caught Specification-of Letters Patent. Patfl'hed' NOV, 14, 19 11- Application filed'gllayf 10, 1910. .Serial No, 560,482. i

by the claws. Preferably a spring throws the delivering device back against a stop, whereby the envelop is thrown out of the delivery device and drops into a receptacle. Said delivery device isconnected to be operated by the pinion before mentioned, and hence, operates once for each operation of the device that feeds" the envelops to the platen.

Other features and advantages will hereinafter appear.

. 15' is to produce a simple and effective device In the accompanying drawings, Figure 1 is a front perspectlve view of an envelopfeeding appliance mounted uponfthe platen frame of an Underwood. front strike writing machine; the platen. frame being shift-- able up and down as usual, and the envelopfeeding devices being shown of light constructionso as to be easily-shifted and also easily borne along by the carriage on which delivering the addressedenvelops.

-' One of the main objects ,of the invention for feeding envelops from a stack to the 70. platen of a typewriting machine. Z A further aim is to provide a device not only compact but also oflight weight, so

that it may be placed upon the carriage of platen; a gear 1 the, platen axle, I said gear and-connected by a link to a rocking the platen,

a typewriting machine .without adding pro- 25 their leading edges rest upon the floor of the receptacle; and thin claws are thrust under theflap of the envelop to take it from r the stack and cause it to advance intothe bite of the platen and the usual pressure- Stl'rollrunnin thereon. This movement ofthe claws is e ected preferably by the platen the means that rotate the being preferablyfixed upon anda pinionmeshing with "itself, or by frame which carries said pair of claws. The pinion is preferably of smaller diameter than the gear, soithat the. rate of y foperation of the claws is made greater' than;

40 the rate of revolution'of the platen,

' avoiding thus the necessity of operating the platen idly during a substantial operation of its revolution.

Another feature of the invention resides 5 in means for delivering the addressed envelops from the platen. This is done by means of another pair of claws, which are mounted to swing forwardly and downwardly toward the platen to catch under the 5 flap o fthe envelop as the latter rises from and then to swing upwardly and backwardly to deliver the envelop. Means are provided for guiding the addressed'envelop upward from'the platen, and to supthe platen is accordingly shown as caught to advance the envelop the platen and the pressure roll running ure, the downward movement; of the envelop-feeding claws has begun, and they are under the flap of the inverted envelop..

positions at Figs. 3-.and 4: are intermediate;

(gram, but showing The positions :at Fig. 2 are at the opposite extreme from Fig. 5, and the ween the bite of L a sectional side elevationshowing Fig. 3 showing the parts as having moved Underwood typewriting machine is mount- 'comprisinf ed by means of an axle 2in a platen frame (to feed the paper) either by means of I hand-wheels 5 upon said axle, or by a linespacing'lever 6 mounted upon the carriage and engaging a slide 7 on the platen frame, the latter having a pawl 8. to engage a ratchet wheel '9 fixed upon the axle 2.

Envelops 10 are stacked in a box, holder or receptacle which may comprise-vertical side plates 11, one or both of which may rest upon the top edge of the paper shelf 4 of the platen frame: said plates united by .,three horizontal-

tie rods

12, 13 and 14, and rear tie rods 15, 16.- The floor of the receptacle may consist of several bars 17 fixed at their rear ends upon the tie rod 16, and'fixed at their forward ends to the tie rod 14:; said members 16 being projected downwardly and forwardly from 14:, as at 18, and inclining toward the platen 1 to form envelop-guiding bars. the receptacle may consist of a number of vertical bars 19, fixed at their upper ends to the tie rod 12, and at their lower ends to the tie rod 13, and extending downwardly nearly or not quite to the floor, so as to leave an opening through which the envelop's'may be drawn out. Only three of the bars 19 are shown, sovthat the front of the holder is open, to permit entrance of the claws by which the envelops are to be drawn downwardly out of the holder. Within the holder is a follower 20 to engage therear of the stack of envelops; said follower preferably having midway its top and bottom edges, apair of cars 21, whereby it is pivoted upon a frame scomprising arms 22, the latter inclined downwardly and rearwardly from the follower and pivoted at their rear ends upon the tie rod 16, and pressed forward by a spring 23; The swiveling of the follower upon the arms or frame 22 permits the latter to press. evenly upon the stack of envelops.

The fioor of the holder 17 preferably-slopes J I downwardly .a'nd' forwardly at an acute angle to the frontthereof, to'assure that the envelops, when they are placed in the holder. shall-be dropped or fanned one be- Y ends 3, and an intermediate paper shelf 4:. The platen or roll 1 is turned I The front of mas er form of a double claw, orof a pair of claws,

fingers, or beaks 24-, which rise and fall in front of the envelop holder, and are pressed rearwardly against the forward envelop by a spring ,25, the latter coiled about a'horizontal rock shaft 26 upon which are fixed the pendent claws. Said rock shaft is shown journaled at its ends'in the forward ends of a pair of

arms

27, 28, the latter fixed at their rear ends upon a 'rock shaftf29, which is journaled in a support consisting of a pair of cars 30 projecting back from the side plates 11 'of the envelop holder. By moving the frameconsisting of the arms27, 28 and rock shaft 29, claws 24: may be raised and lowered} andsince they are constantly pressed back by the spring. 25, they are caused to slip and catch under the flap 31 of the forward envelop, as at Fig. 1. Each claw'is very thin, and by reason of its thinness and length, is rendered highly flexible,

having for this purpose a crank 32, and the latter being connected by a link 33 with a wrist 34 provided upon a pinion 35,=. the lat- Y ter suitably j ournaled at 36 upon the platen frame, and meshing or otherwise connected with a gear 37 whichmay be fixed upon-the platen axle 2. It will be understood that the pinion 35 rotates with the platen, and that at each revolution of the pinion 35, the

claw carrier

27, 28,29, is lifted-and lowered between its extreme upwardposition, as seen at Fig. 2, and'itslowermost position (Fig.

5). The diameter of the pinion 35 may be only about two-thirds that of the gear 37, so that the rate of operation of the feeder may be greater than the rotation of the platen 1, the periphery of whichis usually much greater than the height of an envelop; andby thus relatively increasing the speed or rate of the envelop feeder,'considerable idle rotation of the platen may be avoided, and time and labor saved. In moving from the position at Fig. 2 to that at Fig.5, the link or pitman 33 (through the arm 32) rocks the

arms

27, 28 downwardly, carrying down the claws 24, which, being pressed rearwardly against the forward envelop, catch beneath the flap 31=thereof (Fig. 1)

and withdraw the same from the envelop holder and advance it downwardly along the bent guides 18, 4:, (the latter 'ofwhich bends or curves, as usual, forwardly around the under side of the platen as at 38, Fig. 2), and into the bite of the platen and the pres sure roll 39, which usually runs upon the under side thereof; the flexibility of the claw 24 enabling it to follow the bending or curvature of the

guides

18, 4 and 38, so that it may carrythe envelop right between the

rolls

1 and 39; the point of the claw passing preferably beyond the line of contact of said rolls, as seen at Fig. 5 in dotted lines, before relinquishing the envelop. The pitman 33 now starts to return from the position at Fig. '5 to that at Fig. 2, and, by pulling the arm 32, raises the frame 27 28, to the position at Fig. 2; the platen and its roll 39 meanwhile feeding the envelop forwardly and up past the printing line, that is, the place where the types 40 strike upon the front of the platen, as seen at Fig. 2. The operator turns the platen to carry the envelop up far enough to write the address, andthen rotates is carried up by the coi-iperation of the platen and the usual forward bottom pressure'roll 41, until the envelop is in position to be delivered from the machine. During this rotation of the platen, the pinion 35 is of course rota.ting,.and the described devices are proceeding to feed from the stack a fresh envelop toward the platen. The usual front,

wire guide 42, which, in said Underwood maclnnc, is erected upon a part 43 of the framework of the machine and extends up above the printing point, serves to guide the envelop upwardly from the printing point; and thereafter the envelop may be guided up by a pair of front vertical fingers 44, having forwardly flaring lower ends' 45 in front of the upper end of the guide 42. The addressed envelop, as it rises, slips upon the rear sides of the guides 44; and the roll 41 carries the envelop far enough to be engaged by the active delivering devices, as will be seen atFig. 5.

The envelop-delivering devices may comprise a double claw or pair of thin platelike claws or beaks 46, which extend toward each other from the forward ends of a pair of arms 47, which, like the arms 27, may be placed outside of the envelop holder 11, although supported thereon. The arms 47 may extend to the rear of the envelop holder, and may be fixed upon a horizontal shaft 48, to enable themto swing upwardly and rearwardly to carry the envelop over the-top of the envelop holder, from which point the envelop is discharged and permitted to fiy or drop from the machine. Said rock shaft 48 is Jo'urnalcd in the walls 11 of the envelop holder, and carries a crank 49 havingawrist 50, whereby the envelopd'eliverei'is operated. At Fig. 5, it Will be seen that the addressed-envelop 10 is pressed rearwardly bythe guiding fingers 44, which the platen until the envelop it pushes the wrist fingers are very thin andresilient andform a yielding support for the envelop, the latfor being engaged by the claws4G. lnother words, said yielding guides 44 press the en-' velop r'earwardly against said c aws, sothat the latter, in rising from the position at Fig. 5, may slip under the ends of the flap 31 to catch the envelop, and then raise or swing the latter to the position atFig. 2. It will be noticed that each of the claws 46 has a downwardly and rearwardly inclined or flaring fender 51, whichengage'sthe top of the envelop and presses'thesame forwardly, so that the" envelof'pmay "not be fouled by't'he claw 46, and so gage the front face thereof. smaller fender may be added 52 upon eachof the that said claw. may not drop in front of the envelop or en-.-

claws 46. The delivery arm's47 may be brought down to the 1;)osition'atFig5 by means'of a shoulder or tappet 53, formed on the link to engage the wrist 50 on said operating arm 49. It will beseen' that'during the revolution of the pinion 35 from the position at Fig. 2, the link" i s' swun downwardly about its upper pivot 54 unti the tappet 53 can engagev saidwrist 50, as

shown diagrammatically at Fig. 3'; and

when the rock shaft is driven baekwardly',

50 and arm 4.) rearwardly and forces the rock shaft 48 to swing the.

arms 47 forwardly and downwardlyto the position seen at Fig. 5. The shoulder or tappet 53 preferably open slot in the link 33, the better to control the arms or frame 47. In moving'fr'om the position at Fig. 5, the link 33 isswung up bodily about its upper pivot 54, until said tappet 53 clears the wrist 50, as at Fig. 4'; whereupon a spring 55, coiled around the rock shaft 48, throws the arms 47 rapidly upwardly and rearwardly and against a pair of cushion stops 56 securedupon the plates 11. At' this time, theenvelop 10"is about in a horizontal position, andiits impetus is so great that it continues its move-I, ment, slips off from the claws 46;,flies back, and drops behind the machine'into a basket 57, Fig. 7, which may rest upon the table on which the machine is supported. It will thus be seen. that'the movements'of both the iii-feeding and delivering mechanisms are controlled by the platen, and hence take place in proper relation onetothe other, so

that all the operator needs to do, after stack- 'ing the envclops in the holder is- 'sim'ply to turn the platen and operate the types until The plates 11, at their; lowerife'nds,

forms one edge of an 7 {be. formed with forwardly-extending:arms

"58, to carry. the fingers 44 upon crooks 59 extending toward each other (Fig. 1) said c ooks 59 also preferably provided withsmah pendent fenders 60 near the tenders 45. Each of the arms 58 may have on its lower edge a slot 61, to catch upon a tie rod 62 usually connecting the ends 3 of the platenframe in said typewriting machine;

whether or not the delivering devices are also employed, and vice versa.
