ENVELOP-FEEDlNG ATTACHMENT FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 699,975, dated May 13, 1902. Apparition met Mal-011.31, 1900. serai No. 10,946. (No modi-.1J

.NOLDS, a citizen of the United States, residing at Sterling, in the county of Whiteside and .State of Illinois, have invented certain new .and usefullmprovementsin Envelop-Feeding Attachments for Type-Writers, of which the following is a specification.

My invention relates to certain new and useful improvements in envelop-feeding attachments for type-writing machines intended to lbe used in connection with any kindof machine of this nature to Which itlis adapted, with such modifications, changes, and additions as may be necessary to attach-it'to a particular machine. .g y 1 One of the primary objects of; this invention is to provide acomparatively simple-and inexpensive attachment which lcan be'con nected and embodied with anordinary typewriting machine for-automatically feeding Aenvelops thereto and arranging same in position to receive an address withoutrequiring any attention on thev part of the operator for this purpose. v p

Another object of the .invention is to pro,- vide mechanism and devices which .can be embodied with an ordinary type-writer for feeding envelops thereto automaticallyand which are set in actionby the operator whenj shifting the carriage into position .tobegin a new address.

Another object of the invention is to provide for arranging a supply of blank envelops in a convenient position with relation to the z type-writing machine and fromY whichsup-I ply the envelops are automatically fed one by one into position for receiving the address. Another object of the invention is to provide a carrier intermediate of the envelop'- supply and the platen of the type-writing machine which adjusts the venvelop in its proper position and from which the envelop is fed at the propertime to the platen.

A further object of the invention is togprovide for separating the hold-ing or pressing rollers from the platen at ythe proper time, so thatl the envelop may readily be fed into' position with relation to the platen to receive theaddress. v

My invention also has numerous other objects in View, which will be fully and carefully pointed out hereinafter in the detailed description, among which are to provide stop- ,guides whereby the envelop :is properly adjusted with relation to the-platenandfor releasing these stop-guides, so that the envelop may be fed around the, platen,lfor shifting the carriage and actuating the feeding devices of my improved attachment, and for ac complishing various other movements and results which will be fully explained. ,Y

In the accompanying drawings, Figure l is a perspective view of my improved attachment applied to a type-writing machine, so much of the machine being illustrated as is necessary to understand the application of the invention. Fig. 2 is a top plan View of the machine and attachment as illustrated in Fig. l. Fig. 3 is a front elevation. Fig. 4 is a side elevation looking from the left of the machine, a part of the envelop-supply device being broken away. Fig. 5 is also a side elevation looking at the right of the machine. Fig. 6 is a sectional view. Fig. 7 is a detailed sectional view of the envelop-supply device and carrier, showing these parts in their proper relation to each other. Fig.-8'is a topY plan view of the type-writing machine with the envelopsupply and carrier devices .removed and showing the parts of my inven- Ition which are attached to the ordinary typewriting machine. Fig. 9 is a detail rear elevation of the carriage and parts connected therewith. Figs. 10 and 1l are detail views, partly in section, showing the stopguides and the manner in which they operate. Fig. l2 is a top plan view, partly in section, showing the device for operating the roller-platen of the machine. Fig. 13 isa detailed enlarged cross-sectional view of the platen and showing the holding-rollers. Fig. 14 is a detailed view showing the manner of supporting the carrier. Fig. l5 is a detailed view of the feeding and locking dogs at the envelop-supply.

It will be understood that in the ordinary operation of addressing -envelops, the address comprising three lines of writing, the type-writing machine is operated in exactly the same manner as is -customary without my improved feeding attachment connected therewith, the operator manipulating the keyboard, the line-spacing devices, and the carriage-shifting devices in the usual manner,

IOO

excepting that I provide a special shifting device, which, however, is operated in substantially the same manner as the ordinary shifting device.

Referring to the drawings, in which like numerals of reference denote corresponding parts in all of the figures, 1 designates the frame of the machine to which my attachment is applied, this machine comprising also a carriage 2, traveling on the tracks 3 in the usual manner and provided with a rollerplaten 4, which is mounted in the carriage in the usual manner on a shaft 5. The carriage is also provided with a lever-arm 6, by means of which the platen-feeding dogs 7 and S are operated and the carriage is shifted. The carriage is also provided with a supplementary shifting device 9, as is usual in a machine of this character.

The envelop-supply holder 10 is mounted on a standard 11, which may be connected with the frame of the type-writing machine or otherwise located at the rear thereof. This holder is substantially in the form of a chute provided with the inclined bottom 12, so that the supply of envelops will always feed down toward the open front of the holder. To maintain the supply of envelops in an npright position, I provide stop devices, which comprise the arms 13, carried by the adjustable brackets 14, secured on the sides of the holder by simple screw devices, so that the arms 13 can be adjusted for envelops of different sizes.

The envelops are fed from the holder one at a time, and the feeding devices comprise the slotted holding-dog 15 and the temporary holding-dog 16, Fig. 15, these dogs being independently mounted in the following manner: The temporary holding-dog 16 operates through a slot of the main holding-dog l5,`

and it is carried on a yoke 17, pivotally secured to the sides of the holder at 18, Figs. 4,75, 6. This temporary holding-dog is normally out of engagement with the envelops in the holder, as shown in Fig. 6, and it is caused to rise through the slot of the main holding-dog into a position behind the first envelop and against the second envelop of the supply, Fig. 7, to hold all except the iirst envelop, so that when lthe main holding-dog 15 drops the first envelop is free to fall into the carrier. A bell-crank lever 19 is pivotally supported on the standard and has one arm extending downward to be engaged with the carriage, hereinafter described, so that when the carriage is shifted to begin a new address on a fresh envelop this bell-crank lever will be rocked, thereby causingits horizontal arm to engage and lift the yoke 17 and carry the temporary holding-dog up into engagement with the envelops, as hereinbefore described. The main holding-dog is carried on a rock-shaft 19', which is provided at its outer end with an arm 20, having a cam-shoulder 21 thereon. The yoke 17 is provided with a lug 22, and the arm 2O is heldin engagement with this lug by means of a spring 23, so that while the spring normally holds the arm 2O down and the holding-dogin engagement with the envelops this arm is raised by the engagement of the lug 22 with the cam-shoulder 2l when the yoke 17 is elevated, as previously described, thereby releasing the main holding-dog from the envelops at the same time as the temporary holding-dog is carried up to prevent the envelops behind the first one from feeding. I also provide a bar 24 at the front of the holder, which will preventl the envelops from falling out of the holder improperly during the feeding operation and cause them to drop into the carrier in the proper manner.

From the supply-holder the envelops drop into a carrier, which is supported on the carriage and travels thereon, normally holding an envelop ready to be fedinto printing position. This carrier consists of a plate 25, corresponding in width substantially with the holder and provided with sides 26 and guides 27 to prevent the envelop from falling forwardly out of the carrier. On the back I provide brackets 28, Fig. 1i, by means of which the plate is supported on the carriage, and in this embodiment of my invention the brackets are provided with slots 29 to receive the shaft 30, on which the holding-roller devices are supported. I also provide an arm 3l on the carrier and by means of which the carrier is rigidly securedin place on the carriage.

The envelop drops into the carrier and is supported at or about the middle thereof on the ends of the temporary supporting-arms 32, these arms being rigidly secured to a rockshaft 33, journaled in bearings in the brackets 2S, and their ends normally held in contact with the face of the carrier by means of a spring 34, so that when the envelop drops into the carrier it will rest upon the ends of these arms. One end of this rock-shaft 33is provided with a downturned end 35, which is adapted to be engaged by suitable devices connected with and operated by the carriageshifting mechanism, so that whenever the carriage is shifted into position for beginning a new address upon a fresh envelop the temporary supporting-arms will be withdrawn from their position in contact with the face of the carrier and the envelop which hasbeen supported by these arms will drop into position between the roller-platen and the holding-rollers, the platen being also operated at this time to carry the envelop around into position for receiving the rst line ofthe address.

At the back of the carriage I arrange a lever 36,whichispivotally mounted onabracket 40, secured on the shaft 30 of .the carriage and at or about its middle. One end ofthis lever is provided with a hooked arm 37,which engages and interlocks with a vertically-arranged arm 38 on one end of the shaft 39, which usually carries the scale located adjacent to and beneath the roller-platen. This IOO IXO

gagement therewith, so asto facilitate itsar rangement .relative to theplaten in position for.v printing,.I provide lugs4l onl .the scale-l shafft`239, .which are arranged. to engage thev studs 42,` carriedby the arms 43, Whichl are vmounted on the shaft and carry thehold- It-Will` ing-rollers 44 onf'their lowenend.

I provide a pivoted footpiecc 63 on one end thereof, which is provided with a vheel 64, adapted to be swung into engagement with the teeth of a vertically-arranged rack-bar 65, supported on the frame of the machine at the back thereof. The pivoted end of this footpiece is provided with a projection 66 and connected with the swinging arm 50 by means of a cord 67, Figs. 2 and 7. The footpiece 63 is normally held ont of eagagement with the rack-bar 65 by-means of a spring 68; but when the carriage has proceeded to the left in the printing operation and the handpiece is .pulled to shift the carriage to its initial position and set in action the other devices hereinbefore mentioned the initial tension on the pull-cord 59 will be exerted primarily upon the Swinging arm 50, which is normally held by the spring 68 at an angle to the line of the pulleys 46 and 48, Fig. 2, 'and this arm is swung around into a position substantially parallel with the line of tension on the pullcord, thereby drawing upon the cord 67 and swinging the footpiece 63 on its pivot into engagement with rack-bar 65, Fig. 8. This movement is accomplished very quickly by the initial tension exerted on the pull-cord and before the roller-platen begins to revolve; but as the tension on the pull-cord increases and vthe roller-platen is revolved and the carriage shifted the footpiece 63 acts as a fnlcrum for the lever 36, its heel 6l engaging one of the vteeth of the rack-bar, so as to retard its forward movement and operate to swing the lever 36 on its pivot. Vhen the lever 36 is thus swung on its pivot, the various devices before described are operated for feeding an envelop from the carrier into position for printing and feeding another envelop from the supply to the carrier. As the carriage is shifted to its initial position the footpiece 63 slides over the rack-bar 65 and beyond the same and is returned to its initial position, Fig. 2, by the spring 68, this spring in this operation also drawing the cord 67 taut and the swinging.

arm 50 into its angular position.

The envelop is automatically fed from the carrier into position for printing, and in order that this printing may be done in a uniform manner on all the envelops I provide stop-guides '70, which are located in front of the roller-platen and have forwardly extending ends 71, against which the envelop strikes when it is fed around initiallyin position for printing. These stop-guides are rigidly secured on a rock-shaft 72, journaled in bearings in the frame of the carriage, and the rockshaft and stop-guides are automatically operated whenever the roller-platen is revolved to space a new line. The arm 73 is rigidly secured to the lever 6, Figs. l0 and ll, and provided with a bifurcated end 74, which receives a projection 75, rigidly secured on the rock-shat't72. Theconstruction andarrange- :nent of these parts is such that the stopgnides are initially arranged in a position indicated in Fig. 10, so that when the envelop .ends 7l of the stop-guides, which also act to register the envelop in its proper position in the machine. Then the lever 6 is operated to revolve the roller-platen for a new line of printing, and thestop-guides are swung back from their position in engagement with the envelop, as shown in Fig. 10, into the position shown in Fig. l1, thereby permitting the envelop to feed upward a sufficient distance for a new line of printing, and when the lever 6 is permitted to'return to its normal position, as shown in Fig. IO, the stop-guides will rest against the face of the envelop without impeding or interfering with it in any way, as shown in broken lilies in Fig. l1.

, The lever 6 is provided with a pivoted pawl v76, which engages a ratchet-wheel 77, rigidly secured on the platen-shaft 5, whereby the line-spacing movement of the platen is accomplished, this being a familiar construction.

In order to facilitate the ejection of the printed envelop and the arrangement of a fresh envelop in position for printing, I provide a ratchet-wheel 8O on the extended end of the platen-shaft 5 and a pivoted pawl 8l .on the end of the lever 36, Fig. 8, this pawl `8l being at all times in engagement with the ratchet-wheel 80, so that when the lever36 is swung on its pivot the pawl will operate to turn the ratchet-wheeland platen-shaft 5, and therebyassist the device on the other end of this shaft in accomplishing the ejection of the printed envelop and-the arrangement of a new envelop in position for printing.

This being the general construction of my invention,as shown in the enlbodimentthereof illustrated in the accompanying drawings, the operation, which has been more or less described in connection with the foregoing detailed description, may be brieliy referred to again, as follows: Thel different mechanisms and devices operate simultaneously and are set in action by the single movement of the operator to shift the carriage, and therefore it may be said that by shifting the carriage all the other movements and operations of the machine are accomplished, with the single exception of withdrawing the stopguides from engagement with the envelop. Each envelop passes through a certain cycle of operations during its travel from the snpply to the platen, these operations consisting, -rst, in being fed singly to the carrier; second, being fed from the carrier to the platen; third, being ejected from the carriage, and the operations of tne parts are so timed with relation to each other and connected that a con tinuous stream of en velops is always traveling through the different mechanisms and devices of l he attachment and machine. Assuming that the machine is in-position for operation, one envelop being arranged in position for printing and against the stop-guides and another envelop being supported on the arms 32 in the carrier, the first operation is IOO IIO

Vbeing performed in exactly the same manner as upon any machine without my attachment, and the various stop devices which are usually employed for limiting the length of the lines of printing may be used upon a machine provided with my attachment in precisely the same manner as has heretofore been customary. When the printing has been completed, the carriage has traveled to the left until the footpiece 63 is opposite the rack 65, and the operator pulls `sharply and quickly upon the pull-cord 59. This single movement of the operator shifts the carriage to its initialv position at the right of the machine and sets in action the following mechanisms and devices, to wit: Thejlever 36 is swung on its pivot, and the hooked arm 37 draws backward the arm .38, so as to throw the supportingarms 32 forward and permit the envelop which has been supported thereby to dropiinto position between the roller-platen and the holding-rollers, which have been thrown slightly away from the roller-platen by the same operation of the arm 38,' so as to facilitate the entrance of the fresh envelop into position between the platen and the holding-rollers. At the same time the platen is revolved to eject the printed envelop and feed the fresh envelop around into engagement with the 'stop-guides and in position for receiving the As the carriage is- Vshifted'to its initial position the arm 45, carirst line of the printing.

ried thereby, strikes the bell-crank lever 19, which causes the temporary holding-dog 16 to rise into engagement with the second envelop in the supply, as shown in Fig. '7, while the main holding-dog vl5 drops down outof engagement with the first envelop in the supply, thereby permitting said first envelop to drop down upon the supporting-arms 32 in the carrier. These operations having been all accomplished by the single movement of the operator for shifting the carriage, which corresponds to the usual movement of the operator forthis purpose, as before observed, it is to be noted that the feeding operations for the envelop require no attention whatever lon the part of the operator, and for this reason the machine can be manipulated in the usual way without necessitating the exercise of any peculiar or special skill, by reason of the fact that it has my improved feeding attachment embodied therewith.

The automatic feeding of the envelop makes itpossible to operate the type-writing machine very rapidly, and therefore the operator is enabled to address a far greater number of envelops than has heretofore been possible, because all the time that has usually been required in arranging the'envelop in position for printing is saved by my automatic feed` ing attachment. 1Without my attachment the operator must necessarily shift the carriage, remove the printed envelop, place a fresh envelop in position between the platen and the holding-roller, and revolve the platen until the envelop is arranged in position for prin'ting,it being also frequently necessary to adjust the envelop,so that the printing willbe evenlyand to some extent uniformly done. All of these separate and independent operations are unnecessary when my improved attachment is applied to the type-writing machine. All the envelops are fed and arranged in position for printing in exactly the same manner and precisely the same position, so that the lines of printing are necessarily horizontal and y riage, it is always in position to receive the envelop when it drops from the supply, and this carrier is of a width corresponding substantially to the length of the envelop, so that the envelop when falling upon the arms 2 will be squared in position to be'properly fed to the platen.

My improved attachment can be applied, with such modifications, changes, and additions as may be necessary, to almost, if not quite, all of the diderentl kinds of type-writing machines now on the market, and I believe that the character of my invention is such that-it can be adapted and applied to any type-writing machine. It is also possi'- ble that the invention can be adapted for doing other work besides addressing envelops, and although this is the special object and embodiment ofthe invention I do not wish to be understood as limiting myself specifically thereto. I have not shown all the parts of an ordinary type-writing machine in the drawings, as it is not considered necessary; but itis believed that sufficient of the machine has been illustrated and described to enable those skilled in the art to fully understand the construction and operation and adaptability of my invention.

I have found from a practical use'of machines embodyingmy inventionthat the best results will be attained by giving 'to the platen three successive move ments inrestoring it to normal positionto wit, iirst, a partial rotation, next an endwise movement without rotaton,and, iinally, further rotation in the same direction. The first movement serves to move the addressed envelop around, so that whena fresh envelop starts under the platen there will bevno danger of it overlapping the edge of the printed envelop which would result in its running out of the machine along with the printed envelop when the latter Vis ejected. The second movement restores the platen, with the carriage, to normal position at the commencement of print-.

IOO

IIO

ing.I The third movement serves to eject the printed envelop and run a fresh envelop into position on the platen for printing. These movements will be readily understood by an inspection of Fig. l, which shows the carriage at the end of its travel to the left after the envelop on the platen has been printed, at which time afresh envelop has dropped down into the carriage ready to be dropped down between the platen and feed-roller. The iirst movement above referred to will therefore raise the envelop on the platen a distance of about a half-inch, as shown b v the dotted lines, and before the envelop in the carriage drops down, although this action follows in quick succession. The platen is next drawn fully to the right to its initial position, carrying the addressed envelop in the position shown by dotted lines and the fresh envelop down at the bottom of the carriage,with its lower edge between the platen and the feed-roller. As soon asthe stop 57 passes the end of the bar 58 the tinal rotation of the platen takes place, which serves to eject the addressed envelop and feed into proper position the fresh envelop'ready for printing, at the same time dropping another envelop from the holder into the carrier.

I have found in practice that where the tension on the platen, which yieldingly resists the rotation thereof, is weaker than the tension of the carriage-actuating spring all three of these movements of the platen will be imparted by the cord alone without the necessity for the employment of the ratchet S0 and pawl 81; butl when the reversed conditions arc true-that is, the planten tension is the stronger-then the first movement-to wit, the partial rotation of the platen-will be produced simultaneously with and during the early part of its endwise movement, and the pawl and ratchet 80 and 8l must be relied upon to produce this result, the endwise and final movements being produced by the pull on the cord alone. It is therefore apparent that while under certain conditions, which are generally controllable, the pawl and ratchet may be dispensed with, their presence under any circumstance is not objectionable, and under the circumstances above named, which I have encountered in some type-writers, is essential. The broad idea of my invention, however, is to give to the platen these three successive movements as the result of a single continuous pull on the cord, and I therefore do not desire to limit myself to any particular mechanism by which these movements are accomplished.

I am aware, and it will also be obvious to those who are skilled in this general line of machines that a great many changes, modiiications, and alterations may be made in the construction of the various details of my improved attachment without materially departing from the invention, and I therefore reserve the right and privilege of making all such changes as fairly fall within the spirit and scope of the invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patentisl.
