This invention relates to new and useful improvements in tabulatorsfor typographic machines.

It is one of the principal objects ofmy invention to provide a tabulator for informing the operator of the exact number of type there are in each line of the printing segment or chase plate of a typographic machine. lVfth this information, it is possible for the operator to properly margin each line.

It is another object of my invention to provide means, in connection with this tabulator, for keeping a perpetual inventory of the number of type used in the machine on a particular job or during a certain period.

It is still a further object of my invention to provide means for automatically returning the tabulating cylinder to Zero each time the printing chase plate is indexed for the next line. i

Other important and incidental objects will be brought out in the following specification and particularly set forth in the subjoined claims.

States Letters Patent No. October 2nd, 1928.

My improvements upon this machine lie in the tabulat ng mechanism carried by the keyboard 2. This tabulating mechanism is so constructed that the operator will be informed of the exact number of type there are in each line of the printing segment or chase plate of the machine.

The tabulating mechanism will now be de-- scribed. Projecting upwardly above the platen 3 from the rear portion of the keyboard 2 are two s de arms 4 and 5. These side arms are formed with inwardly project ingbosses 6, 6 at their middle portions. These boss portions of the side arms are formed with axial holes to receive the ends of a slidable shaft 7. (See Figures 2 and 5.)

Loosely mounted on the shaft 7, for a free movement around it, is a drum 8. This drum, which is shown diagrammatically 1n Figure 8, has formed on its outer periphery an indicating band or line 9 which extends from one corner of the drum to the other when the same is flattened out, as illustrated in said figure. Mounted in front of the drum 8 is an indicating scale 10, being placed 1n such a position that when the drum is rotated. the line 9 will come into reg stry with successive graduations on the scale as shown in Figure 2.

The scale 10 is secured to a horizontal, con-raved supporting member 11, which is attached at its ends to the side members 4 and 5. Slidably secured to the member 11, in the manner shown in Figure 7, is a pointer 12 wh ch as a projection 12 that enters the U-shaped or concaved portion of the support-- ing member 11. As shown in said Figure 7, the pointer 12 has a U-shaped lower end, which at its upper free extrem ty is curved for engagement with the rear surface of the con caved portion of said supporting member, whereby it may be firmly held on said support ng member without interference with its free movement along it. This pointer 12 may thus be freely adjusted on the member 11 to bring it to a predetermined graduation on the scale as shown in Figure 2. Accordingly, the pointer 12 may be set in any posi- 1,686,03l, granted gear tion across the scale to show the desired limit of marginal spacing of the type. Then, when thedrum has been rotated to a point where the indicating line 9 coincides with the scale graduation in alinement with which the pointer is set, the operator will know that this marginal limit has been reached.

From Figure 5 it will be seen that the inner end of the drum 8 is fitted at its middle ortion in a. groove in a collar that is freely rotatable around the shaft 7. The other end 16 of the drum is secured at its middle portion to a collar 17 that is also free to rotate around the shaft. 7. Secured in a hole 18 in the collar 15 is a spring 19 which is coiled around the shaft 7 and secured at its inner end in a hole 20in a block 21 firmly attached to the shaft 7 by a set screw 22. It

is against the tension of this spring that the drum is rotated a distance corresponding to each graduated space on the scale when a key 13 has been depressed.

The drum 8 is rotated by the following means when a key 13 is depressed. Secured to the innerend of the drum isa friction disc 23 which is adapted to be engaged by friction pads 24 ecured to brackets 25 attached to the outer face of a gear 27. (See Figures 5 and 6.) This gear has a hub 28 which is mounted on a sleeve 29 that surrounds a reduced portion of the shaft 7 between the collar 15 and a block 30 pinned to said shaft. r

Secured in axial holes in the hub 28 of the 27', are pins'31 which, when the gear is moved inwardly by the shaft 7 will engage the boss 6 on the end member 4. Thus anchored against the boss, these pins will limit the inward travel of the drum 8 when the gear 27 is moved inwardly away from it."

The spring 19 is under sufficient compression to exert an outward force upon the shaft 7. Since the gear 27 is secured to the shaft between its shouldered portion and the block 30, the outward movement of'said shaft induced by the spring will bring the friction pads 24 on the gear into firm'engagement with the friction disc on the drum to rotate the latter when the gear is turned.

The gear 27 is rotated by'the following means. Mounted on a shouldered stud 32 secured to the'end member 4, is a pinion 33 which meshes with the gear 27. Also mounted'on the stud 32 is a ratchet 34 formed with a shoulder 35 which separates it from the pinion. (See Figures-5' and 6.)

The ratchet 34 is actuated by a pawl 36 pivotally secured by apin37 to the free end of a lever 38. The latter is pivotally secured by a pin 39 to the end member 4. I The lever 38 terminates at its rear end in a tail 40 to which one end of a helical spring 41 is secured. The other end of this spring is secured to a pin 42 on the end member 4. This sprmgwithdraws the pawl'36 from engagewith an ear 46 that is adapted to be engaged by the plunger 47 of a solenoid 48. (See Figures 4 and 6.) This solenoid is mounted in a cylindrical boss 49 that is secured to the end member 4. (See Figures 2 and 4.)

- lVhen a key 13 is depressed, the solenoid 48 is energized by means now to be described,

' to move its plunger 47 against the car 46 on the lever 38 to rotate the ratchet 34 one tooth. The latter, through the mechanism described, turns the drum 8 a sufiicient distance to advance the indicating line 9 to the next graduation on the scale 10, thus revealing to the operator that one more type has been placed on the chase plate 50.

Each key 13 is in an electric circuit with a magnetic switch 51 and the solenoid 48. A feed cord 52 which is adapted to be connected to an electric socket not shown, leads to the keyboard 2. Referring to the wiring diagram shown in Figure 11 one feed wire 53 of the cord 52 leads to .a terminal 54 on the magnetic switch 51. The other feed wire 55 of said cord supplies current to the type ejector solenoids 56 through branch wires 57. Each solenoid 56 is placed in circuit with a contact leaf directly below the stem 59 of a key 13. r

The contact leaf 58 belonging to a key 13 is adapted to be pressed into engagement by it with. a contact 60 from which a wire 61 leads to a terminal 62 on the magnetic switch 51. This terminal 62 is connected by a wire 63 to a magnetic coil 64. (See Figures .9 and 11.) The coil 64 is connected to the terminal 54 of the magnetic switch 51 by a wire 65. By a branch wire 66 the solenoid 48 is connected to the feed wire 55, and also to a terminal 67 on the magnetic switch 51 by a wire 68. A branch wire 69 leads from the feed wire 53 to a terminal 70 on the switch 51.

. On themagnetic switch 51 there is a contact leaf 71 which is secured at one end to the terminal block 70 and which is free at its other end to engage the terminal block 67. It will nowbe seen that when a key 13 is depressed, the contact'leaf 58 will engage the contact 60 to close an electric circuit through the magnetic switch 51, whereupon its contact leaf 71 will be drawn by the magnetic coil 64 against the terminal block 67 to close 34 one tooth, thereby rotating the drum 8 a sufficient distance to move the indicating line 9 from one graduation on the scale 10 to the next graduation thereon. r

When the drum 8 has been rotated bythe keys 13 as before described, to bring the indicating line 9 to the scale graduation directly inline with the pointer 12, the operator will immediately know that the predetermined marginal limit in the chase plate has been reached, which means that no more type or quadsshould be placed in that line. At this point thedrum 8 will be rotated in a reverse direction by the following means to return the line 9 to its Zero position with respect to the scale 10.

Referring to Figure 5, the knob 7 2 which turns the platen roll 73 is free to slide inwardly on the platen roll shaft 74. In the path of inward movement of the knob 72 is the lowerfork end of a release lever 75 which straddles the shaft 74. This lever 7 5 is pivotally secured at its upper end by a pin 76 to an overhanging ear 7 on the end member 5. Projecting from the lower portionof this end member is a guide 78 for said lever.

Formed on the upper middle part of the lever 7 5 is a protuberance 79 which is adapted to engage the end of the shaft 7. (See Figure 5.) Now, when it is desired to return the line 9 to its zero position, the knob 72 is pressed inwardly, whereupon it will engage and force inwardly the free end of the lever 7 5. Through its engagement with the shaft 7, the lever 75 will force it inwardly.

Since the rear end of the shaft 7 is provided with a shoulder 80 against which the sleeve 29 abuts, the gear 27 will be forced inwardly by the shaft 7 when the latter is engaged by the lever 75. And when this gear is thus shifted inwardly, it wil move away from the drum 8 because the inward travel of the latter will be limited by the stop pins 31, 31 as before described. The drum 8 being thus released from frictional engagement with the gear 27, will be free to be rotated in a reverse direction about the shaft 7 by the spring 19, which had been placed under torsional tension when the drum was rotated by the pawl 38.

For the purpose of adjusting the zero position of the indicating line 9 of the drum 8, the following adjustable stop means are provided. Referring to Figures 3 and 5, there is secured to the front end 16 of the drum, be yond its center, a stop disc 81 which is adapted to engage a right angled projection 82 on a stop arm 8-3 which is pivotally secured by a pin 84 to the end member 5. The latter is provided with an aii'cuate siot 85 through which the projection 82 is free to move. The stop arm 83 itself is provided with a clearance slot 86 for the shaft 7.

For the purpose of holding the stop arm 83 in an adjusted position to halt the reverse rotation of the drum 8 at the proper zero position for the indicating line 9 withrespect said keys to rotate the drum to to the scale 10, said arm is formed with an arcuate slot 87 through which a screw 88 is inserted into the end member 5. (See Figures 3 and 5).

For the purpose of preventing the shaft 7 from turning when the drumSis rotated,ther is secured to the front end of the shaft a pin 89 which enters a deep recess 90 in the boss 6 on the end member 5. (See Figure 5.)

For the purpose of counting the number of type and quads used in the machine on a particular ob, or during a certain period, I provide a counter 91 of the conventional Vceder type. This counter is mounted in the upper frame of the tabulator in a position to bring its operating pinion 92 into engagement with the gear 27, whereby it may be operated by the latter to record the number of type and quads that have been placed in the printing chase of the machine for a particular job or over a definite period of time. (See Figures 4- and t) In the drawings I have shown the drum 8 housed in a cylindrical casing 93 which is open at its ends for support by the end members f and 5. Through a horizontal open- 9a in the front. portion of the casing, that part of the indicating line 9 which is just above the scale 10 is at all times visible to the operator.
