- the feeding of the envelops is aided by the usual pressure rolls 23, 24, running on the under side of the platen. These rolls prevent the work members from drop-.
- the platen of the Underwood machine shown in the drawings is usually advanced intermittently by a handle 25 having the usual connection to the platen, includingv a slide 26 and a pawl 27, the latter engaging the usual line-spacewheel 28, which may be provided with the usual appurtenances.
- Said drive shaft 17 is carried by a pair of 7 standards or supports 29, 30 in the form of plates, having at their lower ends hooks 31, 32 to catch respectively upon the usual tierod or shaft 33, which extends from end to end of the platen frame, and the rolled or beadportion 34 which is usually formed upon the top of the paper shelf 6.
- Each standard 29, 30 is also provided with a strap 35, adjustably secured thereto by a screw 36 passing through a slot 37; said strap havin a foot 38 to rest upon the platen frame en to which it is secured by a screw 39; the whole forming a light structure of great rigidity, said strap 35 inclining downwardly and outwardly from the standard to buttress thesame.
- the standards may also be connected by tie-rods 40 and 41; and upon these tie-rods may be placed idle pulleys 42, 43, to guide the band strips.
- the envelops 6 are stacked on edge in inverted positions with their tops resting upon the floor 9 of the receptacle, and with their flaps foremost, 'in position to be presented to the band strips, as seen at Fig. 6.
- the envelops are pressed forward against the restraining front plate 10 by means of a vertical follower plate 44 having a horizontal guidingstem 45 slidable forwardly and backwardly in guides 46, 47.
- Bow-shaped springs 48 secured to the guide 47, press against the follower 44, and constantly urge the pack of envelops forward.
- the stem 45 is prolonged rearwardly and carries a handle 49, for convenience in withdrawing the follower plate 44, to permit the introduction of a fresh stack of envelops.
- This protrusion is effected' partly by using the plate 10 to restrain the upper portions of the envelops, and partly by bringing forward the lower portion of the follower 44, as by placing a plate'or bar 51 upon the front face thereof,.as at Fig. 5.
- the strip guiding rolls 42 and 43 are placed just in front of the envelop receptacle so that the thin yielding hooks are guided downwardly in contact, or almost in contact with said front plate 10, and tend to spring rearwardly against and glide down in contact with the body of the envelop and to insert themselves between said body and the protruding flap. From the lower guide roll 43 the band is led directly around the'platen, and thence directly up to the guide pulley.
- the hooks or lugs are spaced at equal intervals upon each strip, and theintervals upon one strip agree with those on the other strip, and the lugs on one are paired with those on the other, so that the work members are presented squarely to the platen or the printing line thereon; the lugs on'one strip cooperatin with those on the other to this end.
- he receptacle may be detachably connected to a pair of horizontal brackets 51*, projecting rearwardly from the standards 29 and 30, by means of threaded studs 52 projecting below the floor of the receptacle and nuts 53 threaded upon said studs.
- the platen 3 and the sprocket wheel 22 thereon are rotated manually.
- rotation is simultaneously'efiected of the driveshaft 17 and the toothed pulley 16, whereby the feeding band or bands 13 are advanced simultaneously with the rotation or linespace movement of the platen.
- the rear hooks 12 descend, they run down past the plate 10, (the upper edge of which is curved rearwardly at 54, so that the sprmgy hooks cannot catch thereon) and press yieldingly against the envelops and engage the flap 50 of the foremost envelop and draw the same downwardly from the receptacle, as seen at Fig.
- the platen is rotated sufficiently to bring the succeeding envelop into position for writing, the envelops following one another at uniform intervals around the platen, as they are caught upon the hooks.
- the envelop rests directly against the platen, which has a specialtexture and consistency, to coiiperate with the usual steel types and ink ribbon, to make a readable 1mpression upon the envelop. It w1ll be seen that an opening is left for the envelop to rest directly upon the platen, at the printing line thereon.
- This opening is secured in the present form of the invention by forming the conveyer of the two strips, which are separated, and have hooks to engage the envelop flap at its ends, the envelop lying between the strips and hence being supported directly against the platen between said strips. The strips are caused to move in mmson by reason of the interlocking of the strips with the connected pulleys 16.
- the handle 49 may be pulled backwardly and a fresh stack inserted into the receptacle, when the operation may be repeated.
- the drive-shaft 17 is mounted upon a pair of posts or sections 56 adjustable vertically in guides 57 formed in the tops of the standards 29, 30; said standards having vertical slots 58 through which project screw studs 59 from the posts 56; the latter being secured by nuts 60.
- a frontguide for the envelops may be formed of wire and consist of an inverted looped portion 61, pendent from arms 62 secured by screws 63 to the standards 29, 30; the guiding portion 61 flaring forwardly at its lower end at a point near the platen 3, in position to catch the leading edge of the envelop and hold it back, while the lower portion of the envelop is curved around the bottom of the laten.
- This guide may be effective until t e envelop resumes its normal straight condition and rides u the rear-- wardly inclined forward reach of the double band, whence it may be removed by the typist.
- the discharge chute 55 shown in Fig. 3, may be employed, the envelop in such case falling onto said chute from the top of the double band.
- Work-feeding devices such as disclosed herein may be operated by pneumatic devices such as disclosed in application 428,050, filed April 20, 1908. No claims are made herein to pneumatic or power-driven typewriting mechanism. Such power-driven devices are disclosed and claimed in my companion application No. 775,654, filed June 25, 1913, in connection with work-feeding mechanisms. The claims herein are broadly directed to work-feeding means for typewriters, but not to power-driven means to operate the same. No pneumatically-operated or power-driven mechanism for actuating the work-feeding mechanism is therefore described in the present case, and reference may be had to said application 775,654, wherein said mechanism is described and claimed.

TYPE WRITING- MACHINE.
new and useful Improvements in Type-Writing Machines, of which the following is a specification.
This invention relates to the work-handling devices of typewriting and analogous machines, and particularly to means for feeding the work members, for example envelops, around the platens; although many of the features of the new construction are usable for also presenting other devices than envelops to the platens of such machines.
An endless band carries the work members and presents them properly to the platen, and the band may be driven by a suitable train of mechanism connected to the platen itself. The band preferably consists of a pair of thin flexible metal strips, from Which project lugs or carriers, to carry the work members; means being provided for preventing the work from falling ofi from the lugs.
When using the improvements for the purpose of feeding the envelops, an envelop magazine is provided, and one by one the envelops are picked up by the lugs or carriers projecting from the endless band, said lugs being for this purpose preferably made in the form of hooks arranged to catch under the flaps of the envelops.
The magazine or receptacle for the envelops is provided with means which tends to project the flaps slightly away from the ping off from the lugs when running around i the under side of the platen.
The work controlling devices are all mounted together with the platen upon the platen frame or carriage of a typewriter. In the caseof the Underwood typewriter, to which my invention is shown applied, this Patented Apr. l3, ll llfi.
Application filed December 23, 1909. Serial No. 534,579.
platen frame shifts up and down for writ.- 1ng capitals and small letters, and the work-feeding or controlling devices are mounted upon a light framework comprising a pair of standards, which are secured to the platen frame of the typewriter, and upon which is mounted a band-driving shaft having a pulley or support over which the band runs, and also preferably having a pinion which .is connected by an endless chain, to a sprocket wheel fixed to the .revolving platen. Said pulley may carry teeth, and the band (or the strips composing the band) is perforated to receive the teeth, and hence the strips are, both positively connected by said pulleys, shaft, pinion, chain and sprocket wheel to the platen, and are caused to travel in unison or as if made in one piece.
It will be understood that certain of the features of the invention, especially those wh1ch relate to presenting work members squarely to the platen by means of an endless band having projections in pairs to engage the work members at their opposite sides, are usable for line-feeding other work members than envelops.
In the accompanying drawings, Figure 1 is a front perspective elevation of, the present' lmprovements used for feeding envelops and applied to an Underwood typewriting machine. Fig. 2 is a front elevation of the same. Fig. 3 is a side elevation. Fig. 4 is a rear perspective view of the envelop magazine. Fig. 5 is a sectional side elevation of the envelop feeding devices. Fig. 6 is a perspective detail, to illustrate the manner in which the hooks catch within the flap of the envelop. Fig. 7 is a detail view of the usual line-space mechanism.
The typewriting machine comprises keys 1, which cause-type bars 2 to strike against the front side of a cylindrical platen 3. The latter is journaled by means of an axle 4 in the ends 5 of the platen frame, said ends connected by an inclined plate 6, which forms the usual paper shelf behind the platen; the lower end of said paper shelf curving around the under side of the platen, as shown. The platen frame rests upon a carriage 7, which, it will be understood, is fed in letter-space direction in the usual envelops 6 are stacked in a magazine or I receptacle at the back of themachine, said receptacle comprising sides 8, a floor 9, and a front plate 10 having at its bottom an opening 11, down throughwhich the envelops are withdrawn. The envelops are picked up byclaws, prongs or hooks12 provided upon work-supportmg bands comprising strips 13, whereby the envelops are carried downwardly and forwardly around the under. side of the platen and up in front thereof to be imprinted by the type bars 2. Each of said bands, strips or belts 13 consists of a very thin flexible metal strip, the ends of which maybe joined in any sultable manner, as by means of a ton e 14 at one end passing through an opening 15 1n. the other end, Fig. 6. The bands may extend upwardly from the end portlons of the platen and run over a pair of remote gulding pulleys 16, forming a support for said bands opposite to the platen, and fixed upon a horizontal drive-shaftv 17, and having teeth 18 to engage or interlock with perforations 19 formed in the separated belts, whereby the latter are positively driven, and caused to travel in unison. The width of the belts or strips is immaterial, but. they are preferably separated, orin other words an opening or space occurs between them, to
permit the envelop to be directly supported I against the platen at the printing line thereon.
The drive shaft 17 is provided with a sprocket pinion 20, over which runs an endless sprocket chain 21; and to the platen 3 is fixed a sprocket gear 22, over which said chain also runs. The parts are preferably so proportioned that the surface movement of each envelop or other work member at each line-spacing operation is exactly equal to the surface movement of the platen. Preferably the feeding of the envelops is aided by the usual pressure rolls 23, 24, running on the under side of the platen. These rolls prevent the work members from drop-.
ping oil from the lugs or hooks 12. The latter, because of their thinness, may be quite yielding, and when necessary may run freely between the rolls 23, 24 and the platen.
The platen of the Underwood machine shown in the drawings is usually advanced intermittently by a handle 25 having the usual connection to the platen, includingv a slide 26 and a pawl 27, the latter engaging the usual line-spacewheel 28, which may be provided with the usual appurtenances.
Said drive shaft 17 is carried by a pair of 7 standards or supports 29, 30 in the form of plates, having at their lower ends hooks 31, 32 to catch respectively upon the usual tierod or shaft 33, which extends from end to end of the platen frame, and the rolled or beadportion 34 which is usually formed upon the top of the paper shelf 6. Each standard 29, 30 is also provided with a strap 35, adjustably secured thereto by a screw 36 passing through a slot 37; said strap havin a foot 38 to rest upon the platen frame en to which it is secured by a screw 39; the whole forming a light structure of great rigidity, said strap 35 inclining downwardly and outwardly from the standard to buttress thesame. The standards may also be connected by tie- rods 40 and 41; and upon these tie-rods may be placed idle pulleys 42, 43, to guide the band strips.
The envelops 6 are stacked on edge in inverted positions with their tops resting upon the floor 9 of the receptacle, and with their flaps foremost, 'in position to be presented to the band strips, as seen at Fig. 6. The envelops are pressed forward against the restraining front plate 10 by means of a vertical follower plate 44 having a horizontal guidingstem 45 slidable forwardly and backwardly in guides 46, 47. Bow-shaped springs 48, secured to the guide 47, press against the follower 44, and constantly urge the pack of envelops forward. The stem 45 is prolonged rearwardly and carries a handle 49, for convenience in withdrawing the follower plate 44, to permit the introduction of a fresh stack of envelops.
As the platen is rotated (by the handwheel shown, or otherwise), the hooks projecting from the rear side of the rear reaches 13 of the band strips, descend in pairs,
with points foremost in front of the front plate 10 of the envelop receptacle, and pass down along the body of the foremost envelop, and simultaneously catch within the flap 50 thereof near the ends of said flap, that is, at the sides or side portions of the envelop; said hooks being preferably formed upon the outer edges of the belts, as illustrated at Fig. 6, and the hooks in each pair being in alinement with each other, for this purpose. The flap portion of the front envelop is caused to protrude slightly through the opening 11 in the plate 10 (said opening being large enough to admit the entire flap of the envelop) so as to insure that the hooks 12 shall catch within said flaps. This protrusion is effected' partly by using the plate 10 to restrain the upper portions of the envelops, and partly by bringing forward the lower portion of the follower 44, as by placing a plate'or bar 51 upon the front face thereof,.as at Fig. 5. The strip guiding rolls 42 and 43 are placed just in front of the envelop receptacle so that the thin yielding hooks are guided downwardly in contact, or almost in contact with said front plate 10, and tend to spring rearwardly against and glide down in contact with the body of the envelop and to insert themselves between said body and the protruding flap. From the lower guide roll 43 the band is led directly around the'platen, and thence directly up to the guide pulley. The hooks or lugs are spaced at equal intervals upon each strip, and theintervals upon one strip agree with those on the other strip, and the lugs on one are paired with those on the other, so that the work members are presented squarely to the platen or the printing line thereon; the lugs on'one strip cooperatin with those on the other to this end.
he receptacle may be detachably connected to a pair of horizontal brackets 51*, projecting rearwardly from the standards 29 and 30, by means of threaded studs 52 projecting below the floor of the receptacle and nuts 53 threaded upon said studs.
In operation, the platen 3 and the sprocket wheel 22 thereon are rotated manually. By means of the chain 21 and pinion 20, rotation is simultaneously'efiected of the driveshaft 17 and the toothed pulley 16, whereby the feeding band or bands 13 are advanced simultaneously with the rotation or linespace movement of the platen. As the rear hooks 12 descend, they run down past the plate 10, (the upper edge of which is curved rearwardly at 54, so that the sprmgy hooks cannot catch thereon) and press yieldingly against the envelops and engage the flap 50 of the foremost envelop and draw the same downwardly from the receptacle, as seen at Fig. 1, and carry it forwardly under the platen and up in front thereof, where the address is written by the operation of the keys 1, the handle 25 being usually grasped and swung by the typist at the conclusion of each line, both to line-space the envelop and return the carriage 7 to-begin a new line. of
writing.
The platen is rotated sufficiently to bring the succeeding envelop into position for writing, the envelops following one another at uniform intervals around the platen, as they are caught upon the hooks.
The envelop rests directly against the platen, which has a specialtexture and consistency, to coiiperate with the usual steel types and ink ribbon, to make a readable 1mpression upon the envelop. It w1ll be seen that an opening is left for the envelop to rest directly upon the platen, at the printing line thereon. This opening is secured in the present form of the invention by forming the conveyer of the two strips, which are separated, and have hooks to engage the envelop flap at its ends, the envelop lying between the strips and hence being supported directly against the platen between said strips. The strips are caused to move in mmson by reason of the interlocking of the strips with the connected pulleys 16.
As soon as all the envelops have been fed, the handle 49 may be pulled backwardly and a fresh stack inserted into the receptacle, when the operation may be repeated. For
keeping the envelop-feeding band 13 in taut condition, the drive-shaft 17 is mounted upon a pair of posts or sections 56 adjustable vertically in guides 57 formed in the tops of the standards 29, 30; said standards having vertical slots 58 through which project screw studs 59 from the posts 56; the latter being secured by nuts 60. The nuts may be loosened and the posts 56 dropped when the machine is to remain out of use to discontinue the fieizessary working tension upon the double A frontguide for the envelops may be formed of wire and consist of an inverted looped portion 61, pendent from arms 62 secured by screws 63 to the standards 29, 30; the guiding portion 61 flaring forwardly at its lower end at a point near the platen 3, in position to catch the leading edge of the envelop and hold it back, while the lower portion of the envelop is curved around the bottom of the laten. This guide may be effective until t e envelop resumes its normal straight condition and rides u the rear-- wardly inclined forward reach of the double band, whence it may be removed by the typist. If desired, however, the discharge chute 55, shown in Fig. 3, may be employed, the envelop in such case falling onto said chute from the top of the double band.
Work-feeding devices such as disclosed herein may be operated by pneumatic devices such as disclosed in application 428,050, filed April 20, 1908. No claims are made herein to pneumatic or power-driven typewriting mechanism. Such power-driven devices are disclosed and claimed in my companion application No. 775,654, filed June 25, 1913, in connection with work-feeding mechanisms. The claims herein are broadly directed to work-feeding means for typewriters, but not to power-driven means to operate the same. No pneumatically-operated or power-driven mechanism for actuating the work-feeding mechanism is therefore described in the present case, and reference may be had to said application 775,654, wherein said mechanism is described and claimed.
Where the hooks 12 are not capable of holding the envelops onto the belt after they have been drawn from the receptacle, I provide a table 78 extending downward from the floor of the magazine or receptacle behind and in engagement with the back reach 13 of the band, to serve as a guard to retain the envelops or work members upon the hooks or lugs. Prior to the withdrawal of the upper edge of the envelop from the re ceptacle, the lower edge of the envelop, with the hooks in engagement with the flap, will be drawn between the table and the belt. Otherwise the envelop once free from its receptacle might drop out of the hooks and fail to'be properly printed and discharged 25 framework, -perforated from the machine. The table cooperates with the band and lugsin conducting the envelops to the platen. The table may press the envelop gently against the belt, creating frictional resistance, so as to prevent the disengagement of the envelop from the hooks. The table 78 may be yielding to accommodate envelops ofvarying thicknesses. Where the flexible band 13 runs around the under side of the platen, the work members are prevented by the rolls 23, 24, or the curved end of table 6, or both, from dropping off from the lugs on the flexibleband.
Variations may be resorted to within the 15 scope of the invention, and portions of the improvements may be used without others.
