23 Claims.

This invention relates to hand and electrically operated multiple tear off bill folders snapping machines and especially of the kind used in snapping apart the copies of bill or statements from the intermediate carbon or layers of carbon paper.

The customary tear off bill folder as illustrated in Fig. 14 of this invention consists of an upper sheet which is used to typewrite the amount of the bill and a number of copies arranged underneath said upper sheet. To facilitate the simultaneous printing upon all of the copies a carbon paper is inserted under and in between each of the bill copies. This operation in the past has been done manually and in the case of ten or more bill copies it required a considerable amount of time to insert a carbon paper for each copy. To save this time these multiple bill folders are delivered for use in prepared forms. In

short, the carbons are placed in position by the manufacturer of the bill folders and the whole number of bills and carbons are secured together on one side through pasting or stapling, (see Fig. 14).

On the side that the bill folders are pasted together there are provided a number of perforations. The other side, the one that is opposite to the side of the bill folder that is pasted, the carbons have a cut out as shown in Fig. 14. After the bills have been typed, the operator grips one side of the bill folder with one hand and the other side with the other hand and tears or prys them apart. As the bills are perforated at one side of the sheet the tearing off operation tears off the bill sheets and separates them from the carbons as shown in Fig. 15,

In the past, this tear off operation has been done by hand. As the operator can not tear off more than a dozen of bills at a time and these bills sometimes may run into hundreds or thousands of individual bill folders, this is very tedious work.

The object of this invention is to eliminate all this manual labor and to provide a machine or device whereby the operator can place a number of bill folders upon it, press a button and the machine automatically will tear the bills apart from the carbons.

Another object of this invention is to provide a tear off machine for bill folders which can be used for bill of 12 inches or longer and for less than 12 inches long.

Another object of this invention is to provide a machine or device to tear off bills from carbons and to provide an arrangement whereby the ma- 55 chine may be adjustable for different sizes of bills.

Another object of this invention is to provide a machine which will be provided with a set of gripping fingers to engage the ends of the bills to be separated from the carbons.

A further object of this invention is to provide an arrangement whereby a pair of drums may be utilized and which drums will be provided with a set of gripping fingers to be located uponthe periphery of said drums and to be used to engage the ends of the bill folder sheets.

A further object of this invention is to provide a machine that will be adaptable for hand or electrical operation.

A further object of this invention is to provide a set of gripping fingers to be attached to a pair of rocking drum segments. These drum segments to be operating in a hinging motion away from each other, l

A further object of this invention is to provide a machine which will tear off bill folders and which will be adjustable for different sizes of bill folders. This machine to be provided with a set of gripping fingers which will be operated horizontally and away from each other.

A further object of this invention is to provide a machine which'will be easy to operate, efficient and inexpensive to manufacture.

Further objects will be seen as the description of the invention proceeds.

Referring to Fig. 1, is the base of the ma chine. Numerals 2| and 22 are a pair of side frame which are attached to the base 20 by screws 23. An outside casing 24 incloses the machine proper.

The casing 24 has an exit opening 25 and 25. A half round out out opening 2! is located at the upper part 28 of the casing 24.

A pair of drums 29 and 30 are located between the side frames 2! and 22. The drums 29 and 30 are loosely mounted upon shafts 3!. The drums 29 and 30 consist of a pair of round side frames 32 and 33. A round shell 34 is placed over the periphery of the drum side frames 32 and 33 to form a continuous drum. An elongated slot opening 35 and 36 is cut out in the drum shell 34. A pair of square shafts 31 and 38 are located within the drum 29 and 341. The ends 3111 and 38a of the square shafts 31 and 38 are round and are fitted into bearings 4-0 and 4| which are located in the drum side frames 32. The other end 372) and 38b of the shafts 31 and 33 is fitted into bearings 42 and 43 located in the drum side frame 33. An adjustable gripping finger 44 is attached to either one of the square shafts 31 and 38 of the drum 29. The drum 3% has two gripping fingers 44 attached to either one of its respective shafts 31 and 38. A number of frame spacer shafts 55 are located within the drums 29 and 39.

The round end extensions 37a and 38a of the square shafts 31 and 38 carry spur gears 45 and 46 respectively. These spur gears are in mesh with a gear segment 41 which is rigidly attached to the shaft 3|. The shaft 3| has a reduced extension shaft am at one end and a reduced extension shaft 3ib at the other end. A slidably mounted clutch member 48 is located over the shaft extensions 3H). A forked arm 49 serves to clutch in the clutch member 48 with the clutch member 56 when the solenoid 5| is energized.

The clutch member 58 is attached to a worm gear 52 which is loosely mounted upon the shaft extension 3| b. The worm gear 52 is operated by a worm 53 which is rotated by a square shaft 56. The shaft 54 is rotated by the electric motor 55 and by the medium of a set of spiral gears 55. The motor 55 and the solenoid 5! are simultaneously operated when the attendant switches in the current by operating a switch.

A pulley 5'! is attached to the drum side frame 32 and is fitted loosely over the shaft extension 31a of the shaft 3!. The extreme end of the shaft extension 310. is secured to a segment arm 58 which is in contact with the limiting stop screw 59 when the shaft 3! is in nonoperative position. A spiral spring 59 is located over the end of the extension shaft 35a. One end 59a. of the spring 59 (see Fig. 2) is attached to the shaft extension 3la through the hub 60. The other end 59b of the spring 59 is attached to a pin 6| which is located on a plate 62 which is rigidly fastened to the sliding bearing 63.

Referring to the sliding bearing 63 it has a pair of slide grooves 64 and 55 which slide within a pair of fiat slide bars 66 and 31. The bars 66 and 61 are attached by the screws 69 to the frame extensions 68a and 68b.

The sliding bearing 63 is split in half and comprises an upper part 63a and a lower part 63b (see Fig. 2a). The pulley 51 is fitted and rests upon the lower part 632) of the bearing 63. The upper part 63a of the bearing is under the ten sion of the coil springs 16 which are located over the shanks of the screws 1 l The upper part 63a of the bearing 63 can slide upon the shanks of the screws H. The screws H are screwed into the lower part 632) of the bearing 83. The pressure of the springs 15 can be regulated by adjusting the position of the screws 'H.

As it can be seen the upper part 53a of the bearing 63 is pressed over the pulley 5'! which is rigidly attached to the drum 29. This action of the upper part 63a upon the pulley 5? is restraining the drum 29 from rotating freely when the drum is in operation. The purpose for this action will be described hereinafter. The drum 30 has a similar arrangement of a split bearing as described for the drum 29. The shaft extension 3!?) of the shaft 3! is also located within a sliding bearing 12. The bearing 12 runs within the slide bars 120. and 1212. These bars are attached to the frame extensions 68a and 68b of the frame 22. The bearing 12 has a lower extension 13 which ends in a bearing member 74 which serves as a bearing for the square shaft 56 (see Figs. 4 and 5).

A pair of threaded shafts 15 and T6 are rotated by the handle 11 and the chain drive 78 when it is required to bring the drums 29 and 35 closer together in the direction shown by the arrows (see Fig. 3). To this effect a threaded bearing 18 is attached to each of the sliding bearings 63 and 12. The threaded shafts 15 and 15 are fitted into the threaded bearings 78. The threaded shafts 15 and 15 are supported upon the side frames 2| and 22 within the bearings 1'9 and 80 which are located upon either end of the frames.

An operating table 8| which is adjustable vertically is used to support the tear off bill folders in the proper position within the machine. The table 8| is arranged to be raised or lowered by loosening the knob handle BI which is located over the screw bolt 82. The table 8| is secured to a supporting I-shaped member (see Figs. 1, 2 and 6).

Referring to the modification of the machine as shown in Figs. 7, 8 and 9, the parts are essentially the same as the ones used in the machine in Figs. 1 to 6 inclusive. In the case of this modification instead of a pair of rotatively mounted drums there are provided a pair of slidable mounted base members 83 and 84. A square shaft 85 is mounted horizontally in side extensions 86 on both sides of the member 83. Another square shaft 8? is mounted in the side extensions 88 on both sides of the sliding member 84. A set of gripping fingers 98 are located on the square shafts 85 and 81. The fingers 39 can be adjusted upon the shafts 25 and 85 by the knobs 9E3.

A hinging arm 9| is hinged at the shaft 92 and 92a at the side extensions 86 and 88. A roller 93 is attached to the end of a hinging arm 9!. The roller 93 contacts an elongated bar 94.

The sliding member 83 and 84 is attached to a link chain 95 and 96 respectively. The link chains are operated through a set of gears 95a and a set of sprocket gears 91 and 98 within the casing 99 of the machine.

A cam I38 which is rotatively mounted upon the shafts Itl has in this case four working surfaces as shown in the drawings. There are also four openings Hi3 located upon the fiat surface of the cam IOfi. When the handle IE4 is operated manually in the direction indicated by the arrow a pin I85 is forced into one of said openings I63. This action will rotate the cam Iilil in the direction shown by the arrow. A roller I86 which is attached to a hinging arm ID? will force the end I38 of the arm N31 to go upwards. As the end m8 is attached to the elongated bar 94 the bar 94 will be raised, the hinging arm 9| will be operated in the direction shown by the arrow and the gripping fingers 86 will be made to grip the ends of the bill folders to be separated from the carbons.

The further movement of the handle I85 will rotate the gear segment III] and operate the gear I89. The operation of the gear I will operate the link chains 95 and 96 and will transmit a sliding motion to the sliding base members 83 and 8 in a direction away from each other.

Numeral III indicates an adjustable bracket which is used in connection with a screw M2 for the purpose of adjusting the machine to be used for difierent number of sizes of tear off bill folders.

Referring to the modification as shown in Figs. 10, 11 and 12 in this case instead of full drums there are used a pair of hinging or rocking drum segments H3 and H4.

A supporting table II5 serves to support the bill folders in the proper position within the machine. A set of gripping fingers H5 are positioned upon square shafts II! on each side of the drum segments I53 and H6. The gripping fingers Iifi are operated by a set of link arms H8, I I9 and I26. A roller I2I is attached to the lower end of the link H9. This roller contacts a cam I22 which is operated by the link arm I23. The link arm I23 is attached to a hinging member E24. The drum segment IM has the same arrangement for operating the gripping fingers I It as described for the drum I I3.

When the handle I25 which is attached to the hinging member I24 and the shaft I26 is manually operated in the direction shown by the arrow, the cams I22 will raise the links I20, I I9 and H8 and force the gripping fingers H6 to contact the ends of the bill folders. The further motion of the handle I25 in the directions shown will force the drum segments I I3 and I I4 to move in a rocking motion and away from each other as shown by the arrows.

This motion will tear off the bills from the carbons. The drum segments are operated over the shafts I21 and I28 which are fitted into bearings I29 and I30 which are attached to the case casting I3I. When the roller I2I will reach the position I2Ia as shown in dotted lines in Fig. 11, a tapered extension of the base casting I3I will push the roller I2I out of engagement with the surface I22a of the cam I22. The base extension is indicated by the numeral I32. This operation will free the gripping fingers and will release the ends of the bill folders and let the bills and carbons fall into collecting baskets or trays (not shown).

Operation The tear ofi bill folder as shown in Fig. 4, consists of a successive row of bill sheets and carbon papers which are stitched together at one of their margins. The bill sheets are perforated underneath the margin where they are stitched together (see Fig. 14). This type of bill sheet tear off folder is not new, it has been used for many years all over the world. The usual way to tear off the carbon pages from the rest of the bill folder is to grip the stitched margin of the bill folders with the thumb and fingers of one hand and the opposite margin with the thumb and fingers of the other hand and give it a quick pull. Bill folders of three or four b-ills can be torn asunder in this manner, but for larger numbers of bill folder sheets, this manual operation becomes too tiresome, especially when thousands upon thousands of bill folders have to be torn asunder, as is the case in bigcorporations such as banks; insurance, electric, gas, gasoline companies, etc.

The applicants device serves to tear off the bill folders automatically by simply placing a number of bill folder sets upon the table BI as shown in Fig. l and press a button (not shown) to start the electric motor 55 that operates the device.

A secondary press button (not shown as it is not a part of this invention) is then depressed. This button connects the solenoid 5| (see Fig. 3) to the electric current. The solenoid armature is stationary attached to the machine proper (above the motor 55) but the solenoid core is attached to the forked arm 49. When the solenoid 5| is energized, the forked arm 49 engages the slidably mounted clutch member 48 to the clutch member 58. The clutch member 50 is attached to the spiral gear 52 which is constantly rotating, being driven by the electric motor 55 and the worm 53.

The clutch members 48 are slidably attached I to the shaft extensions MD of the shaft 3| (see Fig. 5). When the clutch members 48 are engaged with the clutch members 50, the gear segments 41 in both of the drums 29 and 30 begin to rotate. The gear segment 41 which is located inside the drum 29 rotates in an anti-clockwise direction while the gear segment 41 which is located inside the drum 30, rotates in a clockwise direction.

The gear segments 4'! are in mesh with the spur gears 45 and 46 which are attached to the shafts 31 and 38 respectively. The gripping fingers 44 are also attached to the shafts 37 and 3B. When the gear segments 4'! ar rotated, the gripping fingers 44 are moved downwardly and engage the margins of the bill sheets which have been placed upon the table 8| beforehand.

The movement of the gripping fingers M is limited by the limiting bars 45a and the thickness of the bill sheet folder sets. When this limit has been reached, the fingers 44 remain stationary but the drums 29 and 39 begin to rotate.

The margins of the bill sheets are clamped between the bars 45a and the fingers 4d. The rotation of the drums 29 and 3% will raise the bill folder sheets off the table 8! and at the same time they will be shingled, (see Fig. 2). This action of shingling is made possible due to the inner curvature of the table 8|. In this position each sheet is torn asunder separately. This action makes possible the operation of this device.

It can be seen that the bill sheets are not torn asunder all at once but each one separately yet at the same time.

The drums 29 and 30 are kept stationary by the sliding bearings 63. The upper portion of the bearings 63 is under the influence of the spring 10. limit, then the resistance of the split bearing 63 is overcome and the drums 29 and 3B begin to rotate.

After the drums 29 and 38 will turn one half revolution (180 degrees) the switch which con- I nects the solenoid to the current is automatically or manually opened and the rotation of the drums 29 and 30 is discontinued. The shafts 3| being under the influence of the spiral springs 59 are rotated in the opposite direction (back) to their original position. The segments 51 are also returned to their original starting position. As the gear segments 4'! are in mesh with the gears 45 and 46 the return of the gear segments 41 will rotate the gears 45 and 46 and open the I gripping fingers 44 to release the bill sheets on one side of the device and the carbon papers at the other side of the device.
