12 Claims.

This invention relates to tally roll mechanism for accounting machines, particularly to mechanism for moving a tally roll to and from printing position. y

Accounting machines ordinarily have a traveling paper carriage for receiving work sheets such as ledger sheets upon which items entered in the machine are printed.v These sheets are inserted and then removed after a few entries have been made upon them. It is often desirable to have a complete record of all the entries on all the sheets and, for this purpose, a tally roll attachment is associated with the machine, this attachment acting as a support for a relatively narrow roll of paper which is fed upwardly past the printing mechanism to receive the impressions of the type. It is not always desirable to have the items entered on the tally roll stripv andconsequently some means must be provided for moving the tally roll attachment to and from printing position. Various expedients have been employed for this purpose. For example, in Main Patent No. 1,123,337, the tally roll attachment is held out of printing position by a spring and it is then moved into printing position by the paper carriage which has a stop on it that engages the tally roll attachment to move the latter with the carriage as the carriage moves to certain columnar positions. It will be readily seen that, with this construction, the extent of movement of the tally roll attachment depends upon the extent of movement of the carriage and the burden of moving the attachment is placed on the carriage. A modification of this construction is shown in Lundgren, No. 1,195,599, in which a hand operated means is provided for enabling the operator to move the tally roll attachment to and from printing position by a hand lever. In Main Patent No. 1,173,293, there is shown a tally roll attachment that is urged to printing position by a spring, but is normally held against movement by a latch. Depression of the total or sub-total key releases the latch whereupon the spring moves the tally roll to position. It is returned by movement of the machine handle which is connected to it by a tape. A modiiication of this is shown in Lundgren 1,195,598, in which the power for returning the tally roll is taken from the line spacing mechanism.

TheI present invention comprehends a number of improvements over the constructions above outlined including the elimination of the uncertainty of springs in moving the tally roll attachment to or from printing position, the provision of means for positively moving the tally roll attachment to and from printing position by power derived from the operating mechanism of the machine instead of from the carriage,

the provision of a carriage control of the movement of the tally roll attachment which enables the carriage to control the attachment with a very short carriage movement, and the provision of means for selectively positioning the tally roll attachment in a variety of different printing positions topermit figures to be printed in diierent columns on the tally roll strip.

The general object of the invention is to provide an improved tally roll mechanism for accounting machines.

A more particular object is to provide a tally roll mechanism in which the tally roll attachment is positively moved to and from printing position.`

A further object is to provide a tally roll mechanism .in which the operator may, by the manipulation of a single member, condition certain connections and start operation of the machine so that the tally roll will be moved to printing position coincident with the operation of the machine.

A further object is to provide a mechanism by means of which the tally roll attachment may be positioned in more than two different printing positions to permit figures to be printed in different columns or in staggered or offset relation to each other on the tally roll strip.

A still further object is to provide an improved automatic carriage control for moving the tally roll attachment to printing position in predetermined columnar positions of the carriage.

Other objects and advantages of the invention will appear from the following specification and drawings.

An embodimentof the invention is shown in the accompanying drawings, in which- Figure 1 is a right side elevation of the invention applied tothe rear of a Burroughs accounting machine;

Fig. 2 is a perspective view of the tally roll attachment from the rear;

Fig. 3 is a rear elevation of the invention with the tally roll out of printing position, said view showing portions of the paper carriage of a Burroughs accounting machine;

Fig. 4 is a partial plan view of the inventionwith some of the parts of the paper carriage with which it is associated;

Fig. 5 is a-right side elevation of a. modified form of the invention;

Fig. 6 is a partial left side elevation of the total and sub-total mechanism on a Burroughs machine showing the tally roll controls associated therewith.

The invention is shown associated with a Burroughs accounting machine. The general features of this machine are well known in the art and it will, therefore, be described only very briefly. It will be understood that the invention can also be applied to other suitable types of machines.

The machine includes a plurality of amount keys 291 (Fig. l) upon which items may be entered. When the machine is operated after these keys are depressed, the items are entered in an appropriate register (not shown) and a printing mechanism including the printing types 718 are indexed and operated to print the item on a sheet of paper passed around the platen P carried by a traveling paper carriage C. When totals or sub-totals are to be taken they may be taken by depressing the total key 265 (Fig. b; or the sub-total key 265Safter the usual spacing strokes and operating the machine, the mechanism controlled by said keys being well known as shown, for example in Vincent 913,860.

The machine is motor operated and it is set into operation by the depression of a touch or motor bar 10 mounted on the keyboard. When the bar 10 is depressed a lever 11 is rocked clockwise and it, in turn, rocks a second lever 12 counterclockwise. The lever 12 acting through a spring 13 raises a starting link 14 and the latter connects the motor clutch and starts the motor. When the link 14 is raised, it is temporarily held in raised position by a scissors latch 15 that engages over a stud 16 on the link. As the motor operates it drives a general operating mechanism, only parts of which are shown but which includes a full stroke sector 311 which is first rocked counterclockwise from the position of Fig. 1 and then returned clockwise to its original position. As the full stroke sector 311 moves counterclockwise it releases a vthree-armed member 622 which thereupon moves clockwise out of contact with a projection 17 on the latch 18 whereupon the latch is rocked by a spring 19 to engage under the stud 20 on the lever 12, the member 12 being at that time held upward by the scissors latch 15 acting on the stud 16 of link 14. As the full stroke sector rocks counterclockwise a stud 2l on it engages a projection on the link 14 and moves the latter downwardly which disconnects the motor. The lever 12 is not released at this time as it is held upward by latch 18. The spring 13 is simply tensioned until the end of the return stroke of the full stroke sector at which time said sector engages the three-armed lever 622 and moves it counterclockwise resulting in the release of latch 18 whereupon the lever 12 is moved downwardly by the tension of spring 13. The motor control is well known and shown for example, in Vincent 866,750 and Kilpatrick 928,981.

From the above it will be clear that, when the motor bar 10 is depressed, the general operating means is given a forward and a return stroke of operation during which movement the full stroke sector 311 first moves counterclockwise and then returns clockwise to its original position. Upon depression of the motor bar the lever 12 is raised and it is held in its raised position rst by the scissors latch 15 and then by the latch 18 until near the end of the return stroke of lframe of the tally roll attachment.

operation of the machine when the lever is released and returned to original position.

Tally roll attachment The tally roll attachment includes a frame 30 having a pair of side arms 3l (Fig. 2) supporting a shaft 32 upon which a roll of tally paper 33 is mounted. The side arms are fixed rigidly to a shaft 34 mounted to move longitudinally on rollers 35 (Fig. 3) carried by bearing supports 36 fixed to the rear of the machine.

The strip of tally paper from the roll 33 is fed upward, as illustrated in Figs. 1 and 2, past the platen P to an up-feedng and rewind device including a roller 37 that is periodically moved to line space the tally strip. The feeding mechanism is actuated by a link 40 (Fig. 5) which is moved back and forth at each operation of the machine by being connected to any suitable movable part of the general operating mechanism, in this case by one of the arms 613 (Fig. 6) of the familiar restoring bail in Burroughs machines for restoring the actuator racks to which the link 40 is connected by a second link 40. The link 40 is connected at its other end to an arm 41 xed to a feed shaft 42 carried by the The shaft 42 extends across the attachment (Fig. 2) and has another arm 43 fixed to it so that the arm 43 oscillates with the arm 41 and its shaft 42. When the tally roll attachment is out of printing position as illustrated in Fig. 2, the oscillation of arm 43 has no feeding effect on the tally strip. When the tally attachment is moved to any one of its printing positions, a bar 44 moves into the path of the arm 43 so that oscillation of the arm vibrates the bar. The bar is connected to a pawl and ratchet feeding mechanism which steps the platen 37 around to feed the tally strip, the strip being held between the platen and a pivotally mounted feed roller 45 and being rewound on a roller 46 which is stepped around with the platen by frictional contact with the paper on it.

The feeding mechanism for the tally roll strip is supported on the same frame as the tally roll so that it may move laterally with the tally roll to and from printing position, the feeding mechanism moving laterally on

rods

42 and 47.

Connections for moving tally roll attachment to and from printing position pivoted on a bracket 56 (Fig. 3) supported by the f back plate 57 of the machine. The bell crank 54 is operated by a link 58 carrying a stud 59 that engages in a cam slot 60 in one of the arms of the bell crank as illustrated in Fig. 3. The link 58 is slidably mounted on studs 6l and 62, the link being shaped somewhat irregularly but being approximately L-shaped.

Link 58 has an elongated slot 63 in it provided with an L-shaped portion 64. Positioned in this slot is a stud 65 carried by a plate 66 right as viewed in Fig. 3.

mounted by a. pin and slot connection on a link 67 that is pivoted at 68 to. the full stroke sector 311. The pin and slot connection of plate 66 comprises pins 69 on plate 66 extending into slots 70 in link 67. The plate 66is urged to the position illustrated in Fig. 1 by a spring 71 connected at one end to the plate 66 and at its other end to thelink 67.

It will be clear that with the stud 65 in the horizontal portion of slot 63, if the full stroke sector 311 is rocked counterclockwise from its Fig. 1 position, the stud 65 will move toward the rear in the slot 63. The slot 63 is of such length that the full stroke sector may move the limit of its counterclockwise movement without causing stud 65 to engage the end of the slot. Accordingly, with the parts in the position of Fig. 1, the motor bar 10 may be depressed and the machine given a stroke of operation without the link 58 being moved. In other words, with the operating connections for the tally roll attachment in `normal or disabled condition, the tally roll attachment remains out of printing position when the machine is operated, that is, in the position illustrated in Fig. 3.

It will be equally clear that, if the stud 65 should be moved into the L-shaped portion 64 of the slot in the link 58 so as to enable the connections, a counterclockwise movement of the full stroke sector` 311 would move the link 58 rearward during the forward stroke cf the machine and return it forward during the return stroke. When the link 58 is moved rearwardly the bellI crank 54 is rocked counterclockwise as viewed in Fig. 4 which shifts the tally roll attachment to the Conversely, when the link 58 is returned forward the bell crank 54 is rocked clockwise and the tally roll attachment is lreturned to the left to its original position. It

Tally enabling key Referring to Fig. 1 the stud 65, in addition to extending through the 'slot 63 of link 58, extends through a slot 'in one arm of a bell crank lever 81 pivoted at 82 to the machine side frame. This bell crank lever is connected to a link 83 extending upwardly and pivotally connected at its upper end to an arm 84 fixed to a shaft85 that extends across the machine. The link 83 carries a stud 86 positioned to be engaged by a lever 87 pivoted at 88 on a frame member of the machine. The lever 87 is connected by a link 89 to a slidable stem 90 of a depressible key 91 on the keyboard normally urged upward by a spring 9111.

When the tally enabling key 91 is depressed, its stem 90 moves downwardly and the link 89 rocks the lever 87 clockwise. This raises link 83 and rocks bell crank lever 81 clockwise to position the stud 65 in the vertical portion 64 of the slot in link 58. The parts are thus positioned so that when the full stroke sector 311 rocks counterclockwise it will move the link 58 rearwardly to move the tally roll attachment to printing position. Y

The stem 90 of the key 91 carries a pivoted pawl 92 engaging over a stud on the lever 11 associated with the motor bar 10. When the key 91 is depressed the pawl 92 acting on lever 11 rocks it clockwise the same as when the motor bar 10 is depressed and, hence, depression of the key 91 results in causing the motor to give the machine a stroke of operation the same as if the motor bar had been depressed. The parts are timed so that the stud 65 is raised into the vertical shaped portion 64 of slot 63 prior to the time that the machine starts to operate.

This construction provides a ready control of the tally roll attachment whereby, by the simple depression of a single key, the machine may be operated and the tally roll attachment automatically moved to and from printing position. It is not necessary to move a special lever or to 'manipulate a special member in order to position the tally roll and then manipulate a second member to operate the machine.

Tally disabling key It is sometimes desirable to have the tally roll normally in printing position as, 'for example,4 where it is desired to record practically all of the entries on the tally strip. In order to provide for this contingency a modified construction has been provided which is illustrated in Fig. 5. In this construction the tally roll is normally moved to printing position at each operation of the machine and mechanism is then provided such that, upon depression of a key, the tally roll moving mechanism may be disabled.

Referring to Fig. 5 it will be observed that the tally roll is moved to and from printing position by the same connections heretofore described but, instead of the stud 65 being normally positioned in the horizontal portion of slot 63, it is positioned in the vertical portion 04. In other words, the connections for positioning the tally roll attachment are normally enabled. In this connection the link 83 forms a part of the stem of a special key 93 which may be called the tally disabling key. The stem of this key is urged upwardly by a spring 94 to hold the parts in the position illustrated in Fig. 5. The link or stem 83 has an offset portion 95 carrying a stud 96 operating in a slot in a link 97 connected to the lever 11.

In normal operations of the machine, when the motor bar 10 is depressed, the link 97 moves downwardly Without acting on the stud 96. The stem 83 is not moved down and the stud 65 remains in the portion 64 of slot 63. Accordingly, the tally roll is moved to and from printing position as the machine is operated.

If it should be desired to operate the machine ,without having the tally roll in printing position,

the key 93 is depressed which moves the stem 83 downwardly and lowers the' stud 65 into the slot 63 sol that. upon counterclockwise movement of full stroke sector 311, the stud simply moves in slot 63 and does not actuate link 58 to move the tally roll attachment to printing position. Depression of key 93 acts through parts 95, 96 and 97 to rock lever l1 to give the machine a stroke of operation.

This construction thus provides a ready means for operating the machine and leaving the tally l roll out of printing position by simply depressing a single key.

The key 93, when depressed, is held depressed until near the end of the return stroke of the machine by a latch 170 pivoted at 171 and urged when the pass-by pawl 175 on the end of one arm of the 3-armed lever 622 (Fig. 1) which is usual on Burroughs machines, rocks the lever 176 counterclockwise to operate the usual restoring bail 177. The lever 176 has a lateral stud 178 that engages the hooked end 179 of latch 170 to release the latch at the same time the restoring bail is released.

Total keu control of tally In some uses o! the machine it is desirable to print only the totals on the tally strip in which event it is necessary to have the tally roll in printing position only when a total is taken. For this purpose connections are provided which are under the control of the total key whereby the tally roll mechanism is enabled or disabled depending upon the position of the total key.

Illustrated in Fig. 6 is the usual Burroughs total key 265 which, when depressed from the full to the dotted line position, rocks a bell crank lever 100 clockwise, such action resulting in conditioning the machine for the taking of a total in the well-known manner. Pivoted to the bell crank lever 100 is a pawl 101 urged in a clockwise direction by a spring 102 connected at one end to the pawl and at its other end to a stud on a bell crank lever 103 to which the sub-total key 265s is connected. The pawl 101 has an off-set end 104 positioned to bear against a stud 105 on an arm 106 xed to the shaft 85 which extends across the machine and has connected to it the arm 84 (Fig. 1), to which the link 83 is connected.

When the total key 265 is depressed -to take a total the pawl 101 is moved rearward whereupon its offset end 104 moves the arm 106 rearward and rocks the shaft clockwise as viewed in Fig. 6 which would be counterclockwise as viewed in Fig. 1. This rocks the arm 84 upward and raises the link 83 so as to move the stud 65 into the vertical portion 64 of the slot 63. In this way, when the total key is depressed, the connections for positioning the tally roll attachment are placed in operative condition so that the tally roll will be moved to printing position by operation of the machine when the total is taken.

It will be observed, by referring to Fig. 6 that the sub-total key and its bell crank lever 103 are connected by a link 107 to the bell crank lever 100, the link 107 having a downwardly extending projection engaging a stud 108 on the bell crank 100. Accordingly, when the subtotal key is depressed, the bell crank 100 will be rocked the same as it the total key had been depressed. It may not be desirable, however, to print the subtotal on the tally strip and devices have therefore been provided such that, when the sub-total key is depressed, the connections 4for positioning the tally roll are disabled. The pawl 101 that is pivoted to the bell crank 100 has a stud 109 positioned immediately beneath the bell crank 103 of the sub-total key. When the sub-total key is depressed the pawl 101 is rocked counterclockwise to move its oii'set lug 104 out of the path of the stud 105. Thus, when the sub-total key is depressed, the arm 106 is not rocked rearwardly even though the bell crank 100 is moved rearwardly, the pawl 101 moving beneath the stud 105 on the arm 106.

Carriage control of tally roll attachment It is desirable to have the tally roll automatically move to vprinting position in different columnar` positions of the paper carriage. As previously explained, provision was made for doing this in the prior Main and Lundgren patents but, in the construction there shown, the

tally roll attachment was moved by the paper carriage itself which introduced certain limitations that were not desirable, for example, the burden of moving the tally roll attachment was placed on the carriage and the carriage had to move through a relatively long distance in order to move the tally roll to position. These disadvantages are overcome in the present invention by mechanism as follows:

Referring to Fig. l, it will be observed that the rearwardly extending arm of the bell crank lever 81 has a lip 110 extending under one arm of a pivoted bell crank 111 whose other arm is connected to a link 112 (Fig. 3) slidably mounted on the back plate of the machine. The right-hand end of the link 112 as viewed in Fig. 3 carries a spring held pawl 113 positioned in the path of a stop 114 mounted on the rod 115 carrying the tabulating stops of the paper carriage. There may be one or more of these stops 114 and they may be positioned at various -points on rod 115 depending upon in how many and in what columnar positions of the carriage it is desired to have the tally roll attachment in printing posi.- tion. As the carriage moves to a columnar position where the tally roll is to be moved to printing position, the stop 114 for that column engages the pass-by pawl 113 and moves the link 112 to the right. This rocks the bell crank lever 111 counterclockwise and said lever, in turn, rocks the bell crank 81 clockwise. This raises the stud 65 into the vertical portion 64 of the slot 63 and enables the connection for moving the tally roll attachment. When the machine is operated the tally roll attachment will be moved to printing position.

As shown in Fig. 4, the pass-by pawl 113 yields against the tension of its spring when the carriage is returned to the left as viewed in Fig. 3 in order to permit passage of the stops 114.

This construction has the advantage that only a small portion of the movement of the'paper carriage is necessary in order to have the tally roll move to printing position. The paper carriage does not have to move through the entire distance that the tally roll attachment must move. Instead it simply moves far enough to slide the link 112 slightly to the right to enable the connections for operating the tally roll attachment so that, when the machine is operated, the tally roll will be moved through a very-considerable distance to its printing position. A carriage movement of three-eighths of an inch has been found suicient. The construction also has the advantage that the moving of the tally roll to and from printing position is accomplished positively and without adding any noticeable load to the carriage itself such as is done when the carriage must move the attachment.

Printing in different columns on tally strip It has been the usual practice to simply move the tally roll to and from a single or possibly two printing positions, the flgures on the tally roll all being in one or, at the most, two columns.

It is sometimes desirable, however, to print some A the positioning Referring to F'ig. 3, it will be observed that the right-hand side plate 31 of the tally attachment carries a stepped projection or plate 120 which .travels with the attachment. Positioned for engagement vwith this stepped plate is a pawl 121 pivoted on the end of an arm 122 of a yoke 123. The pawl 121 is yieldingly held in position by a spring 124. The yoke 123 is pivoted on a shaft 125 and it is urged in a clockwise direction by a spring 126, its movement being limited by a projection 123a which strikes the shaft 34. This yoke has another arm 127 extending upwardly into the path of a series of rollers 128 mounted on a shaft 129 carried by the paper carriage.

When the yoke 123 is in its normal position, that is, when its arm 127 is not contacted by any of the rollers 128, the spring 126 maintains the yoke in such a position that the pawl 121 is out of the path of the stepped plate 120 and the tally roll attachment is free to move to its extreme limit to the right.

When, however, the arm 127 is engaged by one of the rollers 128, the yoke is moved counterclockwise to position the pawl 121 in the path of the stepped plate 120. It will be clear that, when the pawl 121 is so positioned, it will engage one of the steps of the plate 120 and limit the movement of the tally roll attachment to the right. The printing position of the attachment is thus selectively determined by the rollers 128 on the carriage which may be oi varying sizes to cause the pawl 121 to engage different steps on the plate 120. When the tally roll attachment is arrested by the pawl 121 the full stroke sector 311 continues in its counterclockwise movement without damaging any lof the operating connections due to the fact that the pawl 53 yields. The connections are further protected by the fact that the plate 66 is slidably mounted on link 67 and held in position by the spring 71. Continuous movement of the link 67 to the right in Fig. 1, if the link 58 is blocked, merely tensions the spring 7l.

The number and the size of the rollers 128 and of the steps on the plate 120 may be variedto suit the requirements. The position to which the tally roll attachment is moved in any columnar position of the carriage depends upon the size of the roller 128 associated with said columnar position. The yielding mounting of pawl 121 prevents breakage in the event the carriage is moved by hand to bring a large roller 128 into contact with arm 127 when the pawl 121 is in engagement with a step of plate 120 corresponding to a smaller roller 128. Under such a condition, the large roller 128 would press down on arm 127.but movement of the arm would be prevented by the stepped plate 120. What actually happens is that pawl 121 swings on its pivot and the spring 124 yields. This avoids strain or breakage of parts in the event the carriage is moved in some abnormal way.

From the above it will be observed that the printing position of the tally roll attachment is selectively controlled automatically by the paper carriage and that the moving of the tally roll attachment to selected position may be accomplished either automatically under the control of the carriage or under the control of the total key or the special keys provided for the purpose.

Interlock for insuring that the platen will be in position when the machine is operated In machines of this type as well as in other types of machines, it is highly desirable to be sure that the platen is in printing position when the machine is operated because, otherwise, the printing types will be operated but, because the paper is not within the range of the types, no printing impression will be made. In order to insure that the platen shall be in printing position, mechanism has been provided for preventing operation of the machine unless the platen is in such position.

Referring to Fig. 1 it will be observed that the machine is equipped with the usual line 11nder 130 which bears against the platen P, said line nder being pivoted at 131. Bearing against this line nder is a. roller 132 carried by a lever 133 which is urged in a counterclockwise direction by a spring 134. The upper end of lever 133 is cam-faced and it is positioned to engage a stud 135 on a second lever 136 pivoted at 137. The lever 136 carries a stud 138 engaging the under face of an extension139 of a pivoted lever 140. The lever 140 has a notched shoulder 141 adapted to be positioned under a stud 142 on the pawl 92 that is pivoted on the stem 90 of key 91.

When the parts are in the position of Fig. 1, the starting bar 10 and the key 91 may be depressed freely. When, however, the platen is moved from the full line position to the dot and dash line position of Fig. 1, the line finder 130 is released and the spring 134 rocks the lever 133 counterclockwise. 'Ihe upper end of this lever cams the stud 135 upwardly and rocks the lever 136 clockwise. This rocks the lever 140 counterclockwise and positions the shoulder 141 under the stud 142. This blocks downward movement of the pawl 92 and, as this pawl 92 is pivoted on the stem and is connected to the lever 11 which must move in order for the starting bar to move, it follows that neither the key 91 nor the starting bar 10 can be depressed and hence the machine cannot be set into operation.

When the platen P is moved back to its full line position the lever 133 is rocked clockwise and the parts above described are moved back to normal so as to free the starting bar 10 and the key 91.

A modification of this construction is illustrated in Fig. 5. In this construction a threearmed lever 150 has one arm 151 bearing against the line nder 130 and another arm 152 extending downwardly and provided with a cam face for engagement with a stud on the end of a slidable link 153 that is urged to theright in Fig. 5 by a spring 154. The link 153 has an upstanding arm 155 carrying the stud engaging the downwardly projecting arm 156 of a bell crank lever pivoted at 157. The other arm 158 ofthis lever carries a stud 159 that engages the cam face of the projection 139 of the lever 140.

It will be clear that, when the link 153 is moved to the left in Fig. 5, the bell crank 156- 158 will be rocked clockwise and the lever 140 moved to a position such that its shoulder 141 will be under the stud 142.

The three-armed lever 150 is urged clockwise into engagement with the line nder 130 by a light tension spring 160 which acts to hold the line nder against the platen only lightly, when the platen is in printing position, so as to avoid smudging the paper. As the platen moves away from printing position, the spring 160 moves the arm 150 clockwise sufficiently to cause an elbow 161 on the lever to move above a stud 162 on an arm 163 that is urged clockwise by a relatively strong spring 164. As soon as the elbow passes above the stud 162, the arm 163 is moved clock- -wise by the spring 164 and the stud acts on the under side of the elbow to move the lever 150 clockwise, the action being a wedging or toggle action that enables the spring 164 to urge the lever 150 and the line ilnder 130 into contact with the platen with considerable force. This greater pressure is desirable when the platen is tilted away from printing position in order that the line finder may cause the papers to follow the platen in order that the line finder itself may engage the papers tightly as it is in this position that the edge ot the line ilnder acts as a line finding medium.

When the platen is moved to printing position the line finder 130 contacting the arm 151 or the three-armed lever 150 moves the parts back to normal position.

It is to be understood that the construction shown is for purposes of illustration and that variations may be made in it without departing from the spirit and scope of the invention as denned by the appended claims.
