ALPPAEJATUS 3 3B, FEEDING- Ili l meeroe,

Application filed Jenner-y 2.5,

To all whom it may ooncern:

Be known that I, BERT LANGLEY, e citizen of the United States of America, residing in Crantwood, county of Bergen, and State of New Jersey, have invented a certain new and useful Appmraeus for Feeding Envelops, of which the following is a speci fication.

This invention relates to automatic feeding devices for sheets, cords, envelops and the like, with particular reference to that type of mechanism in which ,the feeding; is done sheet by sheet from a each or pile.

One object of the invention is to provide 1: siingle and eilicient mechanism which will deliver eutonmlicelly single sheets or envelops from 21 steel; or pile, for Whatever purpose such delivery may he required.

Another ohiec't is toedept such a mechanism {or with a typewriter for the auto-- matic "feeding; of envelope, cards and the like into the tjoewriter carriage.

Another ohject is to provide such a typewriter et'ezuzhment with. means to perinil an easy and rapid nwvenient of the device into and our, of operative position.

Anode-i1- obj :zl; so he combine rhe ettachineni; with l'a. typewriter that the normal and easy o1; 'ution of the letter will not he mile 1" ed in any we-3y; and shill other oh jects will appear in the following descrip tion and claims.

ln the drmvings, Figure l is a front elevation of the device as Il10ll1llJQl-UPOD a typewriter; Fig. 2 is a side eleietion, partly in section, aloi f the line 2-2 of Fi i; Fig. 2) is a, front elevation showing a partly eonr pleted movement oi the mechanism; l 4: is :1 sectional pla n taken tl'irough the line 4-4 of Fig. 3; Fig. 5 is a, front elevation showing the mechanism at one limit of its movement; Fig. 3 is a side elevation showing a tilting arrangement; Fig. 7 is u front elevation of the device when in a tilted or inoperative position; Figs- 8,, 9 and 10 illustrate the various phases of the feeding movement; l1 and 12 are detail views showing the application so the feeding plunger of detachable needle points do io'ncd 'lio engage and cause the successive feeding: oi: curds; Fig. 1?, is a perspective view of an angular plate deteehuhly secured to the floor of the chute or holder for the cards or envelops; and Fig. 14 shows e mG(li'llC2L-' lion in the construction and arrangement of Specifieetion of Letsers Serial No. Mihllll.

springe acting upon the secondary feed device The broad features of the inv on includes esupp H; lor the steel; of sheets or envelope to, her an; 1 means to secure their best slniwn l cured to :1 frame pin shack is eonelzzinhly plate 14; and follower urm plate 13 oil; 16, which are k :l'orwnrcl by the spring 17. This ii-rangeni 6 brings the forward envelop in Jo eontael with ll primary feeding; device wQ' Y comprisee n plunger 18, vertically n oveole in e guii o"; 15) loeeted in an upward e el' 7 J i"'l.'m.oe plate 13, us best shown in As shown in ehe stuclnd m on iovel IR- 1? brood inclinee fooe 2d oi l'he under the envelop limp xvi depressed, so i of lhe plunge].-

.elop in the sliuch, v This nu'weincnt oi plunger is effect d by a rain arm 21 iliulcruined at and provided with on open eeni slot 23 which a stud 22L :ictoclied to the upper end of the plunger. ll spring 25 "lends'le hold the Ellll'l 2i and plunger 18 in their upper position, shown in Fig. 1. All the end of the plunger movement. the feed ing oi? the. envelop is still incomplete. as the plunger foe-iii 2! still abuts the forward edge off the envelop and if grim'iers or rolls were hrought in'lo notion at this poi. t, they would seize the plunger as well. ll: is at this instant that the secondary feeding device eoinple'l: the feed.

The seeondury feeding device eonu'irises a lie'ht 'runie or plate 26 hung upon pivots 27 rerried by e yoke The yoke hes bars if, 29 attached to its ei'nls, and these bars 'l ogelher with the yoke are sliclahle verti' cally in the perf rmed lugs 30, 30 of frame plate, 13. The parts described. are normally kept elevated by springs 31, 31 atfollower l5 jlulcruined to you inched to frame plate 13 and engaging the yoke 28. The frame provided with in the present instance, as llllllfilllll suitable -30 v the full extent of its guiding slot 19.

' the'instant the arm 21 contacts with pro jection 33, it ceases to act upon the plunger 18, as may be seen in Fig. 3. The first contact with projection 33 swings the frame 26 to the right'as viewed in Fig. 9 so that it assumes a position back of therear edge of the envelop. the arm 21 and frame 26 is then downward, carrying with them the envelop as shown in Fig. 10; As shown in that figure, the envelop is fed directly into the bite of a pair of , rolls 34, 35, which may be of any description and used for any purpose.

To prevent the envelop from escaping the control of the feeding devices, a pair of drags comprising light leaf springs 36, 36 are attached to the stack support, and bear against the forward envelop so that its free fall cannot take place. Any mechanism or suitable connection that will move the arm 21 downward will cause the feeding of a sheet. This arm may also be operated manually and for this purpose a finger lug 21 is provided, as shown in Fig. 6.

As shown in Fig. 7, provision is made for handling and feeding cards or envelops of diflerentlengths; The support 11 is fitted with sliding sides 37, 37 which are given a simultaneous movement to and from each other by means of a lever 38, pivoted at 38, to which the sides are connected by links 39, 39. the motion being con'n'nunicated through slots 40, 40 located in the way 11. It will be noticed that this mechanism centers the stack as well as giving it proper support.

The mechanism thus far described is capable of wide and general application. Among its many possible uses is its adaptation to the typewriter, and in thisconnection applicant discloses further devices intended to supplement the mechanism already diselosed so as to provide for an effective cooperation of the feeding device and a typewriter.

Referring to the drawings, 41 represents the frame of a standard front Stlll-ZO type.- writer. As best shown in Figs. 1 and 2, a pair of angle plates 42. 42 are secured to this frame, use being made/of frame. bolts 43.- 43 for this pur ose. To the plates 42,

42 are attached the standards 44, 44 united The continued movement of by a cross-rail 45. Bolted at 46, 46 to the cross-rail are members 47, 47 which support the plate frame 13 and mechanism already described. Mecharism is further provided for the automatic control of the feeding device by means of the typewriter carriage. In the present instance this comprises a ratchet arm 48 fulcrumed at 22 and having a ratchet engagement with arm 21 by means of a spring pressed pawl 49. Adapted to coact with this arm is an upright member 50 carrying a roller 51 and shackled to the typewriter carriage 52 at 53.

In operation, the carriage when moved to the right, causes the roller 51 to wipe the arm 48, the latter being moved by the carriage to the right. This movement depresses the arm 21 and effects a feeding operation in which an envelop is entered into the bite of the rollers 54, 55 of the carriage.

For the effective use of a feeding device of this character in combination with a typewriter, means should be provkied for throwing the device into and out of operative position without trouble or loss of time. Accordingly the mechanism described is specially mounted so that this result may be secured.

Referring to Figs. 1, 2, 6 and 7, the members 47, 47 bolted to the cross-rail 45 have in their upstanding ears an arcuate slot 56, concentric with a bearing 57 in the ears in which the stack support 11, 12 may be rotated. Attached to the stadk support and passing through the slots 56, 56 are clamping nuts 58, 58 by which the stack support may be locked in either the full or dotted line positions shown in Fig. 6. It will be seen that this construction permits an easy and expeditious movement of the feeding device into and out of operative position. When the device is thus thrown into opcrative position, the arm 43 may ride over or upon the stud 50 attached to the carriage. if the carriage should happen to be in that position; or the stud 50 would be on the wrong side of the arm 43 if the carriage were at the extreme right when the device was swung forward. To prevent any disablement from this cause. the arm 4 is provided with the ratchet connection ineluding spring pawl 49. so that no interference between the carriage and feeding mechanism can occur.

When a feeding mechanism is used with a typewriter, it is of great importance that the typewriter carriage should not be burdened with even a part of the weight of such mechanism, as every ounce of additional weight superposed on the carriage makes the entire .machine that more sluggish in operation.

mesmeenvelop as well as to move it toward the carriage rolls. Asa result no auxiliary paper" guide is needed t'ti direct the envelop into the bite of the rolls. The envelop is fully corp trolled and has a complete edgewise feed all the way from the stack to the carriage rolls and auxiliary guides do not have to be added to the carriage. The ,only weight added to the carriage is that of the stud 50 which is relatively of but little account. The dciice therefore has the great advantage of not interferingwith the regular operation of the typewriter to the slightest perceptible degree. But while the invention may possess great utility in connection with a type writer, it is not to be limited to this particular use. The feeding mechanism herein d1sclosed has-a. wide range of usefulness; not only for the feeding of cards, envelope and the like, but also sheets of every description, of paper, metal, or other material.

Fig. 14 shows a modification consisting in the substitution for the springs 31 that act upon the yoke 28 of coiled springs 66 surrounding bars 29.

Figs. 11, 12 and 18 illustrate means for adapting the apparatus to feed cards. The feed foot- 20 of plunger 18 is, on each side 7 of the latter, provided with opposite notches 60 in its upper and lower edges. In these notches are removahly seated spring clips 61 carrying needle points 62 extending below the edge of the feed foot and rearwardly inclined or curved, as seen in Fig. 12. When the plunger descends in the feeding operation, the needle points will be carried into engagement with the leading card and move it down into engagement with the paper feed devices of the typewriting machine. On the door of the container 11 is removably at tached a spring clip 63 having at the rear an overturned resilient flange 6 2 that en gages the rear edge of the floor and at the front a downwardly extending curtain or flange 6-3 which aii'ords a guide or support for the card as it moves downward to the feed devices. Such a guide plate may also be used in connection with the feeding of envelops.
