of these taxing districts and also to each generating plant, substatiompole and tower. Acontinuous property record system consists of an installation phase which involves setting 5 up a history recordfor each property location and a set of total quantities or summary records for each unit of property in each taxing district. 7 A history -record provides a permanent record for each location and carries information in regardto the taxing district, property location -number, units of property, quantities, and installation dates with space provided for the addition-of retirement dates. Space is also pro- .vided for future additions and changes and for the work order under which it is done. The information carried in the history records is ob- -tained from field inventory sheets prepared by field engineers, and the material listed is coded by reference to the unit catalogue.

The total quantitiesor summary records are made up from the history records by a process of segregating andtabulating the like units of property listed thereon. The history records serve as intermediate records between the operating and accounting departments. .After the history records are in- I stalled, they are maintained by the operating Qdepartment, and the unit costs are determined through th'e'work order system. The accounting department is interested only in the total quantitiesof each unit for each taxing district. 5 I The maintenance phase of a continuous propverty record system involves the reporting of additions and retirements for each accounting period. Thedate of 'installationfor each unit of property is also of concern when the retirementof the unit is reported.

According to thefcontinuous property record 7 system .disclosedherein in connection with the 40;.typing machine of the" present invention,-a six digit numbering system is employed to designate ;units oftproperty, and the six digit numbers preferably are applied directly to the inventory sheets at the time-the inventory is made in the field.

"more particularly to Figures in turn, supported on -2 l,Fig-ure 8, in the .of drive roller '31 side of the casing carries Referring now to the drawings for a more complete understanding of the invention, an'd 1 to 3, it will be seen that the=typing machine is supported on .a framework comprising four uprights l0, and horizontal frame members H through l5. The framework is additionally strengthened at the front by a jack panel 16 and a'key panel H.

The roll of tape 18 is supported on a:rod 19., frame members I3 and L5. The tape is passed upward through an opening bottomof a casing 22 which issupported-onthe framework and houses the selector switch mechanism generally designated 23. This mechanism comprises a-pair of insulation blocks 2d and 25 which are maintained in spaced :relation by spacer 'members 25. Figure 11, to provide a channel therebetween through which-thetape is drawn. This block assembly is secured in position in casing 22 by suitable brackets '21, Figure 6. Block 24 is provided with a plurality of transverse holes 28 for slidably'aeceiving a plurality of bar-shaped contact :or

switch-elements designated 29. It will be understood that there is one such switch element for each-possible .punchingin the tape for each unit setting or 15 line sections thereof within selector mechanism 23. A cup-shaped housing 3! of suitable insulationmaterial is secured to block 24 and is provided-with-a plurality of'holes 32 in the top thereof through which the upper portions of switch elements 29 pass whereby the housing 3! serves to maintain the switch elements in position for free slidable -movement under. the force of gravity. Switch elements 29 thus bear against the tape 13 between blocks 24 and 25, and when a hole or punching 33 appears under a switch element, the switch element falls through the'tape to contact acompanion switch Switch elements 29 are preferably as shown, for-the connection of or contact element 34. suitably formed. at the top, so as to serve as terminals conductors or wires thereto, and are preferably rounded at the bottom to facilitate sliding movement of the tape and sliding movement. of the switch elements through the punchings therein. Switch elements 34 may be round headed brass screws with the heads mounted flush with the top surface of block25 and secured to the block by nuts 35 which also may serve as term nal nuts for securing wires or conductors to switch elements 3 preferably as shown.

Gasing 48 further com- '95 and 36.

prises a back wall 52 having a suitable opening 53 therein for access to the typing machine enclosed within the casing. Opening 53 preferably is closed by a door 54 which is hinged to back wall '52 as at 55 and has a convenient knob 56 for facilitating opening of the door.

Back wall 52 merges into top wall which extends diagonally upwardly to merge with an arcuate wall portion 58 which is formed concentrically with respect to shaft 42. The arcuate wall merges as at 59 with a front wall portion 6i and the casing is enclosed at the bottom thereof by bottom wall portion 62 which is supported on, and suitably secured to, the upper longitudinal framework members.

Fifteen identical typing bars, each having a central opening 69 and generally designated by the numeral 63, are loosely pivoted on shaft 42 and maintained in the spaced axial relation thereon best indicated in Figure 6 by any suitable spacing means such, for example, as by washers and collars, not shown. Each typing bar comprises a pair of diametrically opposed circular segments 69 and 65, Figure 12. Segment 64 is the heavier of the two segments whereby this section is normally urged downwardly under the influence of gravity against a suitable stop 56. The arcuate face of segment 64 is provided with a set of imprint characters 9! numbering 0 to 9. These may be secured to the typing bar in any convenient manner, or may be formed integrally therewith if desired. The arcuate face of segment 65 is formed with a series of ten ratchet teeth 68 by means of which the typing bar may be moved pivotally on bar 42 to bring a desired imprint character thereon into the proper position with respect to the imprint mechanism, as will appear more fully hereinafter.

Also pivotally mounted on shaft 42 is a rocker arm assembly generally designated 69 which comprises an arcuate panel 19, concentrically arranged with respect to arcuate wall 58 of casing 48, and a pair of arms Ii and 12 formed preferably integrally with panel I0 and having suitable openings for loosely receiving shaft 42.

Panel I9 has secured thereto a pair of brackets I3 and 14 which, in turn, have a plurality of op erating magnets 75 carried thereby. There is an operating magnet for each of the fifteen typing bars, seven of the operating magnets being carried by bracket l4 and the other eight by bracket I3. The magnets are staggered in brackets I3 and 19 so that the armatures I6 of the magnets are positioned directly above the typing bars 63 respectively, as best appears in Figures 1, 4 and 5. The armatures for the operating magnets carried by brackets 13 are pivotally mounted and maintained in spaced relation in any suitable manner on a shaft 71 which is supported in brackets 78 and I9. Similarly, the armatures of the operating magnets carried by bracket F4 ar pivotally carried on a shaft BI supported in brackets 82 and 83.

The rocker arm 59 carries a manual operating bar or lever 84 which is supported on panel in spaced relation therewith by suitable posts Arm ll of rocker arm assembly 69 carries a pawl 87 for engagement with ratchet wheel at on the return or upward movement of the rocker arm assembly, thereby to rotate shaft 42 and advance the tape, as will appear more fully hereinafter. of armatures i6 is shaped as a pawl as at 88 and extends through openings 80 and I 00 in panel "I0 and arcuate wall 58 respectively into engagement with the ratchet teeth 68 of electrical insulation material whereby the pairs of sliding contacts 90 and 9| are carried thereby insulated from each other. There is a row of ten pairs of these contacts for each operating magnet, the ten pairs of contacts corresponding respectively to the ten ratchet teeth on the typing bar associated with the operating magnet. For each row of these contacts there is a pair of cooperating contact pins 92 and 93 carried by moving panel 70 and adapted to slidably engage successive pairs of contacts 90 and SI as the rocker arm assembly 69 is moved downwardly. Panel 19, for this purpose, preferably is formed of suitable electrical insulation material whereby the pairs of contacts 92 and 93 may be insulated from each other. These contacts are connected to the ends of the winding of the operating mag net individual thereto, as may best be seenin Figure 9.

Sliding contacts 90 and 9I are secured to panel 89 as by screws 94 which may also serve as binding posts for conductors or wires secured thereto.

A roll of paper 95 is carried on a rod 96 which is, in turn, supported in brackets 91 and 98 sebottom plate 62 of casing 48. The from the roll is drawn over a roller 99, thence between this roller and an idler roller IOI'in rolling contact therewith, and thence under a second idler roller I02 and outwardly of casing 48 through an opening I03 in front Wall 6|.

Rollers 99 and I 9| are pivotally supported in a pair of L-shaped brackets or levers I04 and I05 which, in turn, are pivotally supported as at I86 in brackets Iill secured to bottom plate 62 of casing 98. Bracket levers I94 and I05 are slotted as at 08 whereby the levers may be adjusted along pivotal point I06 so that the portion of paper 95 in contact with the imprint characters 67 on the typing bars 63 moves with the characters during the final downward movement of the rocker arm assembly, the lower edge of panel I9 thereof engages the upturned end portion I09 of levers I04 and I05 causing them to rock about pivots I05, thereby to move the paper on roll 99 into contact with the imprint characters through inking ribbon IIO.

The ribbon H9 is carried in the usual spools III which in this case are driven through bevel gears II2 from a ratchet wheel I I3. The ratchet wheel, in turn, is driven by a pawl II4 which is pivotally secured as at II5 to a lever H6 in turn, pivotally supported on end wall 49 as at I". The other end of lever I I6 extends through an opening I I8 in top Wall 21 and terminates in a horizontal end portion H9 adapted to be yieldably urged against the upper edge of panel 10 by a spring I 2| acting on the lever, whereby end portion II9 follows the panel upon downward movement of rocker arm assembly 69 to cause pawl II 4 to slip over ratchet wheel H3 and engage another tooth thereon, movement of lever II 6 in this direction being limited by stop l22. When panel I9 is restored to its initial position during the return movement of rocker arm assembly 69, the edge of the panel engages and drives end portion I I4, thereby to forcibly return lever H6 to its position in Figure '7 whereby the ratchet wheel I I3 is advanced one tooth and rib,- bonI I9 is advanced to a new setting. I

Paper 95 is advanced one line on the machine in a similar manner. For this purpose, roller 99 carries a ratchet wheel I23 which is engaged by a pawl I24 pivotally secured as at I25 toa lever I26 which is pivotally secured to end wall I of casing 48 at I21. The other end of lever I26 extends through an opening I28 in top plate. 51 of casing 43 and terminates in a horizontal end portion I29 for engagement with the edge of panel I6 under power of spring I3I. Forward movement of end portion I29 under power of spring I3I is limited by stop I32. Operation oi lever I26 to advance ratchet wheel I23 forward one tooth is the same as operation of lever H6 in advancing ratchet wheel II3 forward o ne tooth and the previous description of theopera-Q tion of the latter ratchet wheel, therefore, will sufilce for both.

Imprint levers suitable openings tion 6|.

The jack panel I6 comprises a plurality of jacks I34 for receiving plug ended cords as in conventional switchboard practice. There are two jacks for each pair of selector switch elements 29 and 34 these being electrically connected on either side of the switch comprising a pair of elements. An additional pair of jacks I35 and I36 connected to the incoming power line, which may be a conventional 110 volt source, are also provided. The jack panel further carries a search lamp I31, a location lamp I38, and an oiT-on power switch I39.

The key panel I! comprises a plurality of keys I4I of the normally closed push button type which open the circuits therethrough when the keys are pushed. There is a pair of keys for each pair of selector switch elements 29 and 34, the keys being connected to the jacks individual thereto.

A selector switch code is employed for electrically connecting the sliding contacts of each row of contacts on panel 89 to the proper switch elements 29 in the selector switch mechanism 23. This code and lead connection designation is as follows:

By reason of I04 and I05 extend through I33 therefor in front wallpor:

special operating signals this arrangement each sliding contact 99 in each row is connected to B lead 1,

2 or 3 and each contact 9! of each row is connected to G lead l, 2, 3 or 4. This means that the winding of each operate magnet I5, when energized, is connected on one side to a B leadand on the other side to a G lead. All of the B leads 1, 2 and 3 are connected together and to the live side of the power source supplying the typing machine, and

side of the power source.

In the operation of the typing machine to all of the G leads 1, 2,3 and; dare connected together and to the grounded' column of Figures 13a and key I4I, upper l0 produce a history sheet, tape I8 is fed through selector switch 23 by means of crank 43 until the first group of punchings on the tape is reached. These will be the punchings for the location number. Lever 84 is then moved down. During the downward movement of panel 16, various pairs of contacts 92 and 93 in the digit rows under Unit of property (Figures I3a and. I3b) will be momentarily energized by certain pairs of contacts and 9I for the reason that certain pairs of selector switch elements 29' and 34 corresponding thereto in the Unit of property digit columns will be closed in accordance with the punchings in the tape corresponding to the location number. This will cause momentary energization of certain operate magnets I5, and as the magnets are energized their armatures will move into engagement with the ratchet teeth on the typing bars individual thereto whereupon the typing bars will be moved with the rocker arm assembly 59 to move the imprint characters 61 on the typing bars into a position to be engaged by print mechanism operates during the final movement of the rocker arm assembly. This action is illustrated in Figures 4 and 5 wherein sliding contacts 90 and 9I corresponding'to imprint character 6 have been energized, thereby to cause the operate magnet to pick up the foremost typing bar 63 in Figures 4 and 5 as pawl 16' moves to engage the fourth ratchet tooth down, which ratchet tooth corresponds to imprint. character number 6 on the bar. As the energizing circuit to the operate magnet is broken, as. contacts 92 and 93 move on to the successive pairs of sliding contacts 90 and 9I, operation of the magnet is continued for a suflicient length of time by the use of shading coils or rings on the magnet, these being conventional and therefore not shown.

Assume that the foremost typing bar of Figures 4 and 5 corresponds to the operate magnet 15 of the thousands digit under the Unit of property 131). The circuit to operate this magnet and cause its armature to engage the fourth ratchet tooth down, as in Figure 5, is traced as follows: from the live side of the power source through power olT-on switch I39, conductor I42 and the common B lead to the lower B2 lead which is herein also designated as conductor I43 for purposes of illustration, lower B2 key I4I, lower B2 jack I34, B2 switch elements 34 and 29, upper B2 jack I34, upper B2 B2 lead herein also designated as conductor I44 to facilitate tracing of the circuit,

sliding contact 96 corresponding to imprint character number 6, pin contact 92, winding of magnet 15, pin contact 93, sliding contact 9I corresponding to imprint character 6, upper G3 lead which is also designated as conductor I45, upper G3 key I4I, upper G3 jack I34, G3 switch elements 29 and 34, lower G3 jack I34, lower G3 key I4I, lower G3 lead also designated as conductor I46, and thence through the common G lead-to ground potential at the other side of the power source.

On the return movement of the rocker arm assembly 69, the typing bars are released and fall under influence of gravity to the position of Figure 4, the ribbon III) is moved to a new setting, paper 95 is advanced a length corresponding to the spacing between adjacent lines of typing thereon, and the tape is advanced 15 lines through the selector mechanism 23 by action of pawl 81 which engages ratchet wheel 44 during the paper as the im-;

the return motion. A new set of circuits is now. established by the selector mechanism whereby multiplier, quantity, unit of property and installation date numbers are printed on the paper when lever 34 is moved downwardly. After a series of such operations .have been performed, lamp I 38 on jack panel IE will light, thus indicating that all units of property have been recorded for the particular location number recorded. The paper is then withdrawn a full sheet length and torn ofi.

In preparing a summary sheet, a search circuit is built up on the jack panel according to the number of the unit of property to be tabulated. Assume, by way of example, that the number is 753024. This number corresponds to the following combination of B and G leads:

Number Digit B lead The first step is to open all the keys associated with these leads under the appropriate digits columns. These keys are shown in dashed lines in Figures 13a and 13b and to build up the search circuit by connecting the selector switches 29, 34 corresponding to these BG combinations in series by means of plugended cords inserted in the jacks of panel I 6.
