To all whom it may concern Be it known that we, VVILLIAM H. Mo- AnDLn and ROBERT B. MoARnLE, citizens of the United States, both residing at Camden, in the county of Camden and State of New Jersey, have jointly invented certain new and useful Improvements in llnvelop, Card, and Sheet Feeders for Type-Writers, of which the following is a specification.
Our invention has relation to certain im provements in a class of automatic envelop and card feeders for typewriters of the type illustrated in United States Letters Patent, No. 9S5,4-29,-granted to us under date of February 28th 1911, and in which is described a frame for carrying a pack of enof March 14th 1911, in which as described therein, an approximately horizontal. paper carrying frame has its discharge end so constructed as to guide the paper downwardly to the typewriter, according to a v peculiar constructive arrangement of paper recelving mechanism unfittcd to receive sheets or envelops in a horizontal position, but with the same provided with bands or tapes stretched around the bend formed, and bearing on idler rolls carried by the bend of such frame.
The principal objects of our said invention are first: to provide simpler means to transmit motion to various mechanisms of the frame; second, to the provision of suitable mechanism to separate envelops, cards or sheets standing or lying in an inclined position, while feeding; third, to the provi* sion of the machine with means to protect the envelops, cards or sheets after being acted upon by the typewriter; fourth, to the provisi n of means to mount flexibly feeding me hanism so as to allow the same to bear alt all points of contact uniformly against the envelops, cards or sheets while feeding; fifth, to the provision of means so arranged as to adjust pressure of feeding mechanism against envelops, cards or sheets to be fed; and sixth, to the provision of means so arranged as to maintain the envelops, cards or sheets at a proper angle While in bearing contact with feeding mechanism.
With these and other objects in view, as will be hereinafter more fully described, our said invention generally stated, consists in' certain novel features of constructive arrangement, as illustrated in the acconmanying drawings and as, particularly pointed out in the claims.
It is to be understood that various modifications in form, proportions and minor de tails in the constructive arrangement as illustrated of the feeding device, may be made without departing from the scope of our said invention or sacrificing any of the advantages of the same.
In the accompanying drawings z--Figure 1, a top or plan view of the said feeder, embodying main features thereof. Fig. 2, is a side elevation, looking from the left. Fig. 3, is a sectional elevation of the feeding and separating mechanism, longritlulinally along the line X--X of-l ig. 1, Fig. 4, is a front elevation of the feeding roller, showing adjustment of the pressure of same against a pile or pack or envelops, cards or sheets to be fed; and Fig. 5, is a view of part of the bottom frame of the device, showing a spring for maintaining the euvelop supporting plate carriage against feeding mechanism and also convenienti'ueans for backing the carriage from said feeding mechanism so as to permit of the inserting of a fresh supply of envclops, cards or sheets.
In all the views of the drawings, similar numerals of reference are used to indicate correspomling parts.
Referring now to the drawings, 1, is an envelop, card or sheetcarrying frame supported and connected to a typewriter, in a manner similar to what shown in our United States Letters Patent No. 987,097, dated March 14, 191].
a, is the platen of a typewriter.
a, is a sprocket secured to the spindle of the platen and connected to the sprocket by means of a link belt. The sprocket is secured to the shaft 2, carrying a sprocket 2, and which in turn transmits motion to a sprocket 8 by means of a link belt. The s rocket 8 is secured to and rotates with t e shaft 8, carrying the sprocket 1(5. The sprocket 16, transmits motion b means of a link belt to a sprocket 17, on t e hub of aspool-like feed roller or Wheel 11. The feed roller or wheel 11, is carried by and rotates on a shaft '7. which is supported at its ends by means of ari'risf prfmembers l) and 10. The members 9 and lOQare pivotally mounted on the said shaft 8.
12 and 13, are rubber bands or the like forming frictional means arranged around the enlarged ends of the feed roller or wheel 11. This feed roller or wheel 11, as shown in Figs. 2, 3 and 4, rests on the idler rolls 50 and 51, which are mounted on the underside of the frame 1, and extend up through openings in said frame. The mem bers 9 and 10, at one end are movably mounted on the shaft 8, and fulcrumed thereto is the feed roller or wheel 11, and the opposite free ends are beveled or inclined respec- 'tively, at 9 and 10 as shown in Figs. 1, 2
and 4, and engaged by thumb-screws 19 and 20, extending through a bar 18, which latter is held in place b ears 25 and 26, secured to the frame 1; an these thumb-screws when operated are brought into engagement with the free ends of said members 9 and 10, to permit of adjustment of the feed roller or wheel 11, to or from the rollers 50 and 51, beneath. In Fig. 4, the springs 19 and 20 bear respectively, on the thumb-screws 19 and 20, with a pressure sufficient to automatically lock the same at whatever point turned. The above referred adjustment for movably supporting the feed roller or wheel 11, serves a two-fold purpose of first keep in the said feed roller or wheel 11, from,
being lifted by the weight of the envelope, cards or sheets at C, pressing'down the incline; and second, of adjusting the distance of the said feed roller or wheel 11 from the stack of envelops, cards or sheets C, at C The springs 19 and 20 as shown in Fig. 4-, bear respectively, on the screws 19 and 20,
and by a pressure sufficiently to automati cally lock the screws at whatever point turned.
14 and. 15, are two members carried by the shaft 8, 'to-maintain the envelope or other,
articles at the- )roper angle, while being advanced to the eed roller or wheel 11.
28, is a supporting member for carrying the separating mechanism, as shown in Figs. 1 and 3, and which may be supported at one end by the shaft 8, and at the other by the shaft 27. The shaft 27 is supported at its ends by means of said cars 25 and 26, as fully shown in Fi 1. The spring member 41, as illustrated in Fig. 3, may be secured to the shaft 27, by a screw bolt 29, or other suitable means, to hold the spring member passing throu h the opening 41, under a pressure in contact with an adjustable thumb-.screw 30.
40, is a pin or projection on the member 41, passing through an openin in the supporting member 28, to keep t e connected members 41 and 42, from swinging out of alinement.
46, is a portion of the frame 1, bent at an angle. 45, is a member screwed or bolted to a piece it, and projecting into a small opening in the frame 1.
44, is a frictional surface embracing the top of the member 45. The member 43, is rotatably or otherwise mounted on the end of the member 42, and adjusted to or from the surface 44,- by means of .the thumbscrew 30, so as to accon1modate=the same to the thickness of an envelop, card or sheet; the two members 43 and 44, engaging the envelops, cards or sheets at their middle portion only thus to allow of the free passage of the same at the corners thereof.
The pile or pack of envelops or other articles C, are pressed by a spring or by. gravity bear against the frictional periph eries of the feed roller or wheel 11, and are kept at the proper angle for feeding by means of the members 14 and 15. The first envelop c, of the pack or pile is shown between the member 43 an surface 44. he end of the second envelop d, being pressed downward so as to come in contact with the frictional surface 44, and held back until the envelop (2, has passed through the said opening. To the shaft 2, is secured two pulleys 3 and 4, as illustrated in Fi s. 1 and 2, and over which pulleys pass t e endless bands, tapes or belts 5 and 6, and around and over rollers 58 to pulleys 49" and 49, and back again to the pulleys 3 and 4." I
48 and 48 are brackets bent around and over the curved end of the frame 1 at 1, as illustrated in Figs. 1 and 2, and supporting at the outer ends the shaft 49, on which are rotatably mounted, the pulleys 49 and 49*.
The forks 34 and 35, as illustratedin Figs.
.the pullevs 3 and 4, and which in conjunction with the forks 59 and 60, at the back of the said pulleys, are provided so as to pre vent the ands, tapes or belts from workin ofl' of said pulleys. To the rear of the fee ing mechanism is an inclined envelopplato 21, adjustable to different angles, as shown in Fig. 2; and on the carria e 21, which is mounted upon wheels or rol ers to follow the envelope or other articles C, down the inclined portion of the frame 1, so as to support and hold the same at the roper angle, to be, engaged by the feed ro ler or wheel 11.
36, as illustrated in Figs. 2 and 5, is a pin or projection carried by the under portion of the front end of the carriage 91 and passing down through the slot 57, in the frame 1, so as to guide the carriage and hold the angle or envelop supporting plate at right angles to the travel of the carriage. The other end of the carriage is held in line with the slot 57, by a pin or projection 2-37, connected with the said carriage. The s, 'd pin or projection passes through said slot 57, as shown in Fig. 5, and engages a spring 38, attached to the bottom of the frame 1. The said spring 38, tends to .push the carriage 21 toward the feeding mechanism. At the end of the member 37, it is arranged ring or hook-shaped and through which passes a lever 54, pivoted at 55, to the bottom of said frame 1 The lever 54, extends outward beyond the side of said frame 1, to provide a linger-hold for backing the carriage 21, away from the feeding mechanism so as to insert a fresh supply of envelope or other articles for being fed to the typewriter.
39, as illustrated in Figs. 2 and 5, is a member carried by the frame 1, and bearing and traveling back and forth on the rollers 56. The rollers 56, are carried and support ed by the typewriter, in a manner as shown in our United States Letters Patent No. 987,097, dated March 14th 1911, aforesaid.
(30 and 60, are guides arranged so as to be adjusted to various sized envelops, cards or sheets and adapted to be released from said frame 1, by means of ordinary clamps ortho li e5.
illost typewriters more particularly the visible type, have guides in front of the platcnto hold the sheet or other article un i t'reed from the writing point, and which causes a sheet or other similar article to lean backward, and-in many cases to again enter the receiving roll r of the typewriter, if not restrained. '0 have provided a member 24:, as illustrated in Figs. 1 and 2, which provides for such conditions and which is pivoted to the sliaft's'ti), and rests on the platen immediately in rear of the top thereof, and on which envelope, or other similar articles pile or collect after passing through the typewriter platen-mechanism, each envelop or article being pushed upward by the rotation of the platen, aided by the next succeeding envelop or other simi ar article, still in the grip of the said platen-mechanism.
its the pile or pack of envelops or other similar articles have a tendency to shuilie sidowisc from concussions of the typewriter, while resting on the member 2%, hence the member 22, is so arranged and mounted in the block 23, as to prevent such action. The block :23, may carried by the said bracket 1.8. Also the said member 22, made so as to be adjustable to or from the end of the pile or pack of envelops or other 23. The said arrangement may be placed (in either or both sites of the envelops or other similar articles as may be preferred in practice.
