Referring in detail to the various views of the drawings, in FIG. 1 a printer shaped to conform to a conventional fountain pen embodying one form of the invention is shown and designated generally at 10. The printer 10 comprises a casing or barrel 12 having an elongated cylindical hollow body 14 formed of plastic or other suitable material. The body 14 is open at both ends. At one end, the top end as viewed in FIG. 3, the body is narrowed and formed with opposed socketed recesses 18. At the other end, the body is also formed with in ternal opposed enlargement 20, with opposed socketed recesses 22. The narrow top end is adapted to be closed by a semispherical cap 24 having a solid. body portion 26 and a depending internally screw threaded skirt portions 28 threaded on the external threaded enlargement 16.

In accordance with the invention, an endless belt 30 moves longitudinally of the body inside the body. The belt moves around upper and

lower rollers

32, and 34, respectively. The upper roller 32 is carried by

opposed trunnions

36 and 38, the trunnions 36 being rotatably mounted in a socketed recess 40 in the wall of the body 14 of the barrel and the trunnion 38 being longer than trunnion 36 and journalled in a socketed hole 42 in the Wall of the. body, opposite the recess. A hand wheel 44 is fixed on the protruding end of trunnion 38. The lower roller 34 is carried by a pair of

trunnions

46, 46 journalled in the socketed recesses 22.

The belt is formed of rubber or other suitable material and carries a plurality of blocks 48 in spaced relation for the entire length of the belt. Each block 48 carries thereon in the outer surface thereof raised printing characters, such as a letter of the alphabet as indicated at 50. The

belt is slightly wider than the blocks .and on the outer surface of the belt opposite each block there is imprinted a character corresponding to the printing character on the block as indicated at 52.

.socketed recesses 18 in the enlargements. The roller 54 is inked by means of a carbon ink block 58 slidably loosely in a rectangular recess 60, square in cross-section, in the solid body 26 of the cap 24, and loosely seated on the periphery of the roller. A compression spring 62 having one end impinging against the base of the recess 60 and having its other end seated on the block resiliently holds the block on the roller.

In use, the belt with its printing characters thereon is moved around manually by means of the hand wheel 44, the block 48 with the character thereon protruding outwardly of the opening in the bottom end of the body 14 as best seen in FIG. 3. At the same time, the characters 52 identifying the printing characters 50 on the belt ride along the body of the barrel behind a narrow elongated window 62 formed in the barrel. The barrel 12 of the printer can be easily and readily held between the fingers of the hand 64 for pressing the printing characters 50 onto the surface of a horizontally supported member, such as a sheet of paper 66, as seen in FIG. 1.

In FIGS. 6 to 8, inclusive, a printer 10' embodying a modified form of the invention is shown. The printer 10' differs from the printer 10 in that the cap 24 is hollow and has a flat top surface. In printer 10, the trunnions supporting the upper roller 32 are journalled in opposed recesses in the body 14' of the barrel 12.

In this printer 10, the inking mechanism is different from the inking mechanism used for inking the printing characters on the blocks 48 of printer 10. Herein an elongated rectangular fabric printing ribbon 70 is used in place of the carbon inking block 58. The ribbon 70 is wound around a supply roller 72 supported by

trunnions

74 and 76 journalled in opposed socketed recesses 78 in the wall of the body 14 of the barrel 12 at the top thereof. A gear 80 is fixed on trunnion 76 intermediate its ends. From the roller 72 the ribbon passes downward through a guide slot 82 in an inwardly projecting lug 84 on the inner surface of the wall of the body of the barrel closely spaced from the roller 72. The ribbon continues downwardly of the body of the barrel in contacting relation to the outer surfaces of the blocks 48 on belt 30', following the belt around the bottom thereof and passing upwardly still in contact with the outer surfaces of the blocks 48', upwardly through a guide slot 86 in a lug 88 on the opposite side of the wall of the barrel and upwardly around a take-up roller 89 supported by opposed trunnions 90 and 92. Trunnion 90 is journalled in a socketed recess in the wall of the barrel and trunnion 92 is journalled in a socketed hole 94 formed in an enlarged portion 96 of the wall of the barrel opposed to the recess journalling the trunnion 90. A knurled knob 98 is fixed on the outer protruding end of trunnion 92. A gear 100 is fixed on the trunnion inside the body of the barrel, meshing with an idler gear 102 fixed on a shaft 104 journalled in opposed socketed recesses 106 in the wall of the body of the barrel. The gear 102 is in mesh with the gear 80 fixed on the trunnion 76 of the roller 72.

In all other respects, the construction of printer 10' is similar to printer 10 and similar reference numerals are used to indicate similar parts.

In use, the belt 30' is moved around by means of the hand wheel (not shown) on the end of one of the trunnions supporting the roller 32. The blocks 48' with the printing characters 50 on the outer surfaces thereof move around wiping against the inking ribbon 70 for the entire journey of the belt. Upon downward pressure on the barrel 12', the raised printing character 50' on the block 48' protruding from the open bottom end of the barrel will be pressed against the inking ribbon 70 and the ribbon will make an impression of such character on a surface similar to a typewriter.

In FIG. 9, a modified form of case or barrel 12" is shown which can be used in place of the case or barrel 12 or 12'. The barrel 12" is sectional composed of a section 110 and a section 112. The sections are semi-round and hinged together by means of hinges 114. Section 110 is provided with a spring clip 116 on the outer surface thereof for clamping the barrel on the edge of a patch pocket in a garment. The free long edge of section 112 supports a pair of spaced spring lugs 118, 118 having protruding

balls

120, 120 adapted to contact the long free edge of section 110 and snap into interlocking position with said section 110 for holding the sections closed.

.4 When the sections are in closed condition, the top of the barrel is closed and the bottom thereof is open.

In FIGS. 10 to 12, inclusive, a printer 10 embodying a third form of the invention is shown supported in the fingers of the hand 64' of the user. This printer 10 consists of a case or barrel 12" with a hollow cylindrical body 14" open at both ends. The bottom open end is formed with internal opposed enlarged portion 20". The open top end is adapted to be closed by an elongated cylindrical cap 24' having a depending flange 28 coacting with an upstanding flange 124 on the top end of the body 14", to hold the cap in place.

A belt assembly 126 is slidably mounted in the body 14" of the barrel. The belt assembly comprises a frame 128 composed of paced side bars 130, 130 and an end bar 132 joining the side bars at one end. The other end of the frame is open. The frame supports upper and lower rollers 32" and 34", respectively, between the side bars. An endless belt 30" moves around the rollers. The side bars 130, 130 are formed with outstruck lugs 134, 134. A coil spring 136 surrounds the side bars and endless belt and has one end seated on shoulders 138 formed on the enlarged portions 20" with its other end impinging against the

lugs

134, 134 on the side bars of the frame whereby the belt assembly is urged upwardly. A hand wheel 44' fixed on one of the trunnions 38 supporting the upper roller 32" is adapted to move the belt 39 around the frame 128.

A plunger assembly 140 is slidably mounted on the cap 24' above the belt assembly. This plunger assembly comprises an elongated sol-id cylindrical plunger body 142 with a reduced upstanding post 144 connecting the body 142 to another shorter cylindrical body 145. A transverse passage 146 in the post 144 slidably supports a pin 148, projecting from opposed side of the post. One end of the pin is adapted to ride on a tapered inner surface 150 of the cap 24". A substantially rectangular shaped block 152 having a reduced end portion 154 is slidably mounted in a slot 156 formed in the cap 24". A leaf spring 158 is secured at one end to the inner end of the reduced portion 154, the other end thereof impinging loosely against the shoulder 160 formed on the under side of shorter body portions 144, said leaf spring engaging the other end of the pin 148. The block 152 has a curved bottom side 162 conforming to the shape of a finger of a user and with its attached leaf spring is adapted to slide up and down along the slot 156 in the cap. A compression spring 164 has one end seated on the top surface of the short body portion 145 and its other end impinging against the base of the cap 24" whereby the plugger assembly is urged downwardly against the frame 128 moving the frame downwardly against the action of coiled spring 136 whereby the type on the block 48" protrudes outwardly of the opening in the lower end of the barrel as seen in FIG. 11.

In use, as seen in FIG. 10, the cap 24" is grasped in the fingers of the hand of the user with the first finger inserted under the finger block 152 and the thumb upon the top of the cap. The plunger assembly is pulled upwardly by the forefinger on the block 152 releasing the pressure upon the frame whereupon pressure of the thumb is exerted downwardly on the cap 24" and body 14" of the barrel thereby pressing the type on the lowermost block 48" protruding through the opening in the bottom of the barrel onto a sheet or the like on a supporting surface impressing said type on said sheet. The belt 30" with blocks 48" and types is moved along the barrel by means of the hand wheel 44". During the movement of the belt, the types on the blocks 48" wipe over opposed felt inking pads 166 secured on the inner surface of the barrel intermediate its ends, thereby keeping the type sufficiently inked for printing.

In FIG. 13, a fragment of a printer 10a embodying a fourth modified form of the invention is shown. The printer 10a differs from the printer 10 of FIG. 10. In addition to the felt inking pads 166 there is suitably supported inside the body of the barrel 12a below the inking pads a roll of carbon paper 170, the individual sheets 172 of carbon paper being detachable by means of a tear line 174 therebetween. A slot 174 is formed in the body of the barrel across the space where the roll of carbon paper is positioned so that individual sheets 172 may be extracted for use in making carbon copies 176 of original work 178. In all other respects, the printer a is similar to printer 10".

In use, suflicient individual sheets 172 of carbon paper are pulled outwardly of the body of the barrel through the slot 174 for the job at hand. These sheets 172 are placed between the paper sheets desired such as the sheet marked first copy in FIG. 13 and the original sheet marked Original is superimposed over the carbon sheet 172 on the sheet marked first copy. The barrel is manually pressed downwardly upon the original sheet 178 whereupon the inked type on the block 48a protruding from the opening in the bottom of barrel 12a is impressed upon the original sheet 178 and the same impression is made on the sheets 176 marked first copy and second copy due to the carbon sheets superimposed thereon.

FIGS. 14 to.16, inclusive, illustrate a fifth modified form of printer 10aa with a hollow cylindrical sectional case or barrel 12aa similar to barrel 12" and closed at both ends. The top wall 180 is formed with a circular opening 182, and the bottom wall is formed with a vertically disposed slot 184, intersecting the round bottom Wall 185 and the opposed sides of the body of the barrel.

An endless belt assembly is mounted in the body of the barrel. This assembly corn-prises large and small upper and lower rollers 32m: and 34aa, respectively, supported by trunnions 3611a and 38aa journalled in opposed recesses 42aa formed in the inner surface of the body of the barrel. Another small roller 186 is fixed on trunnion 36aa at the top, and a larger roller 188 on one of the trunnions 46aa at the bottom. An endless belt 3041a extends around the upper trunnion 3841a and one of the lower trunnion 46aa, and a second endless belt 189 extends around the upper trunnion 36m: and the other lower trunnion 46aa alongside of belt 3011a. Belt 30aa carries a plurality of blocks 48aa on the outer surface thereof in spaced relation. The blocks have type 504m in raised relation thereon. The type may consist of letters, numbers and/or symbols. On the endless belt 189 characters 521m in the form of letters are impressed thereon. During the movement of the endless belt 30aa around the body of the barrel, the blocks 48cm with the type 50aa thereon protrude outwardly of the top wall 180 thereof, and the bottom periphery of the roller 188 extends through the slot 184 in the bottom wall 185 of the body of the barrel below the rounded bottom wall of the body of the barrel.

In use, the body of the barrel is held in the fingers of the hand in upside down position as seen in FIG. 14 so that the type 50aa on the protruding block 48aa may be impressed upon a sheet of paper of the like supported on a horizontal supporting surface.

In order to change the character to be printed, the body of the barrel is held as shown in FIG. 14 with the bottom roller 188 and belt 189 engaging the supporting surface whereupon manual pressure is exerted laterally in the directions of the arrows shown in FIG. 14 thereby turning the bottom roller and belt 189 which belt transmits the turning movement to the upper trunnions 36aa and 38m turning the belt 30aa the desired distance.

In FIG. 17, a printer 10x embodying a sixth modified form of the invention is illustrated. The printer 10x comprises a hollow cylindrical sectional barrel 12x such as shown in FIG. 9, with a circular hole 194 in the top wall and being open at the bottom. A clip 116x for clamping the printer to the top of a pocket of a garment is secured to one of the sections of the body.

In this form, an endless belt 30x similar to the belt 30aa shown in FIG. 15 is mounted in the top end of the body of the barrel 12x, and .a separate similar belt 196 6 is mounted in the bottom end of the body of the barrel. The

trunnions

46x, 46x of the lower rollers 34x of both

belts

30x and 196 are journalled in socketed recesses in the inner surface of the wall of the body of the barrel 12x.

A block 48x with type on the top belt 30x protrudes through the upper and a block 48x of the lower belt 196 extends through the opening in the bottom end of the barrel 12x. The type on the blocks 48x on the top endless belt 30x are preferably lower case or small letters and the type on the blocks on the bottom endless belt 196 are preferably capital letters.

In FIG. 18, the seventh form of printer 10xx is shown embodied in a ruler 200. Herein the ruler 200 has an elongated solid body 202 rectangular in plan, one long side being enlarged as indicated at 204, the other long side being slated as indicated at 206, with a straight edge 208. The surface of the slanted side 216 is graduated in inches as indicated at 210. The end edges of the body are fiat and straight as indicated at 212 and 214. The enlarged long edge 204 is formed with an elongated compartment 216 extending from the straight end edge 212 and opening through said straight end edge to a point closely spaced from the other straight end edge 214. The compartment communicates with a slot 218 in end edge 212. A slot 220 is formed in the flat broad long edge 222 of the body adjacent the straight end edge 214. Slot 220 communicates with the compartment 216.

In accordance with the invention in the compartment 216, an endless belt 30xx passes around supporting rollers 32xx and 34xx fastened to the side walls of the compartment by trunnions 36xx and 36xx, respectively. The belt carries blocks 48xx with type 5020: mounted on the outer surface thereof, the blocks with type projecting outwardly of the slot 217 in the end edge 212, during movement of the belt caused by a knurled drive wheel 224 rotatably mounted on the opposed edge walls of the slot 218, the inner periphery of the wheel contacting the belt.

, In use, the ruler is placed in upright position with the end edge 212 lowermost and upon downward pressure against the type an impression will be made on a sheet supported on a supporting surface. The belt can be readily moved manually around by means of the wheel 224.

' In FIGS. 19 to 21, inclusive, a printer 10aaa embodying an eighth modified form of the invention is shown. The printer 10mm comprises an elongated block 12am: having wooden body rectangular in configuration and cross-section. The body is hollow with side walls 230 a top wall 232, end walls 233, and being open at the bottom as viewed in FIGS. 19 and 20. A partition wall 234 divides the interior of the body into a pair of

compartments

236 and 238 extending the length of the body. The top wall 232 is formed with two series of spaced openings 240, inside by side relation. The openings lead to the

compartments

236 and 238 therebelow. A plurality of blocks 48mm with type 50am on the bottom faces thereof is slidably mounted in each

compartment

236 and 238. Each block has an integral upstanding stem 242 square in cross-section, extending upwardly and outwardly of the respective opening 240 and the top surface of each stem has imprinted thereon a character 244 corresponding to the type character 50mm on the block 48aaa, to identify the type. The stems constitute push buttons. An L-shaped metal flexible leaf spring 246 is suitably secured at one leg 248 to the inner surface of the respective side wall of the block, the other leg 250 being disposed horizontally and extending across the compartment. An inking pad 252 is secured to the inner surface of the leaf spring by adhesive 254. The horizontal leg of the spring seals the compartment off from air thereby keeping the pad moist. The block 48mm seats on the pad on the horizontal leg of the spring for inking the type on the block. A metal clip 116aaa is mounted on one of the side walls 230 for supporting the printer on the pocket of a garment.

In use, the printer 10aaa is superimposed over a sheet 256 of paper to be printed upon and a block 48aaa pushed down by the finger of the user as shown in FIGS. 19 and 20 forcing the leaf spring with pad downwardly and against the inner wall as seen in FIG. 20 leaving space for the block to move downwardly against the sheet of paper. The block is retracted automatically by the leaf spring.

A nint-h modified form of printer 10xxx is illustrated in FIGS. 22 to 25, inclusive. The printer comprises a case or barrel 12xxx with an elongated semi-cylindrical or semi-tubular body of suitable plastic material, with end walls 260 and being open at the bottom as viewed in FIG. 22. One side of the elongated body is formed with a plurality of arcuate slots 262 in closely spaced relation. A round shaft 264 extends inside the barrel from end to end thereof and rotatably mounted on the shaft, there is a plurality of disc-shaped type carriers 266 in side by side relation opposite the slots. Each disc type carrier 266 includes a circular body with central hole 268, with a stem 270 protruding radially and tangentially from the periphery thereof and extending through the opening in the bottom of the body of the barrel. The periphery of the body is cut away adjacent the base of the stern 270 as indicated at 272. On the opposite side of the body, the periphery is formed with spaced transverse shallow grooves 274, defining a portion 276 having a flat surface upon which is a suitable type character 50xxx. A character 52xxx is imprinted upon the outer flat surface of the stem 270, corresponding to the type character 50xxx in order to identify the type character. An elongated fabric inking pad 280 is suitable secured to the inner surface of the barrel 12xxx of a width and in a position to be wiped by the type character 50xxx during its movement around the barrel.

In use, a type carrier 266 is rotated manually by the finger of the operator in the direction of the arrow in FIG. 23 whereupon the type character 50xxx is moved into operative position in the opening in the bottom of the barrel as seen in FIG. 24, the body of the carrier moving along its respective slot 262 and being guided by the edge walls thereof. Downward pressure on the barrel causes the type character to be impressed upon the surface of the sheet to be printed. The type carrier 266 is manually retracted to normal position.
