In ,the aforesaiddmwings, ALt() lrepresents ern the movements ofthe the frame of the machine, ll the amount keys, l2 the special keys, 13 the counter wheels 71 the 'counter operating segments,4 l5 theindicators, 1G. the main operating lever, 17 the cash drawer, and 18 the print- A ing segments.

Described 1n' general terms, the depression ot an amount key operates a graduated lever 19, which is moved into the vpath of a ste segment 20, which, upon bein released ropsuntil arrested by the' stop ever 19.' A segmentalgear 2l, coperating with the segment 20, positions t-he indicators.

of gear wit-h the pinions ot the counter- 1 wheels 13. Whenthe yoke 22 descends accoi-ding to the degree of movement of its step segment 20, its respective lever 71 is set accordlngly, so thatwhen the (counter is thrown in and the lever 7l subsequently re turned to its normal position by the closing of the cash drawer, the registration is effect-- ed. The movements of the indicator-operai ing step trames 20 also position the printing segments.` Y

.The ceg/ banksf-Itwih be seen by reference to Fig. 1 that the machine illustrated is a five bank machine, including four amount banks and one special key bank, the latter including in the present instance a no sale key land a cash key. This special bank, however, may include a series of nine keys if so desired, which keys may represent either a number ot clerks or differentv de f partments. The amount banks cover units and tens of cents and units and tens of dollars. All of the keys in the amount banks cooperate with the registering devices, the

vindicating devices and the recording devices hereinafter described, but the keys of the4 special key' bank coperate only `wi/tlie/speably numbered head 25. The Shanks 24 are mounted in apertured guidesplates 26 and 27, forming part of the main frame, in such manner as to practically radiate from the main transverse shaft28. Each of the key shanks is provided with a transverse pin 29 t which operates through a suitable elongated slot 30 formed in a` wall 31 which is fast to` the main frame beside its particular bank of keys. Each of the pms 29 1s adapted to contact with the cam edge 32 of one of a serres 5, of hook-projections 33 formed ou the piv- -34 is provided with a pendent arm 35 which is formed at its lower end with a locking nose (See Figs. 2 and A latch-plate 39 fulcrumed on a transverse shaft 40 is provided witlra locking stud 41 anda llocking recess 42,- the latter being arranged to receive va stud 43 mounted upon a Apendent arm 44 which is formed integral with its respective yoke -22 hung loosely upon the shaft 28, the

yokes 22 being nested and arranged to operate lone within the other in a'inanner well known in the art. Then the parts are in their normal positions, shown in Fig. 2I the pin43 engages the rearwall of the recess 42 and thus holds the .latching-plate 39 in its elevated position. ln order-to prevent the descent ofthe latelrplates 39 in the bank in which no keys have been operated, I provide an additional latchmg means in a hook 45 which is formed'on the lower end of the segmental graduated lever 19 and normally lies, as shown in Fig. 2, in the path' of the stud 41 so that when the plate 39 is partly relieved of the pressure of the stud 43, it will he arrested by the stud 41 striking the hook The arm 44 will thus remain latched.

v It will be seen from the above that when a key in a bank has been operated andthe lever 19 forced rearward, that the hook 45 will be also forced rearward so far that the pin 41 is free to descend with its plate 39 and thus unlock its respective yoke 22. The lever 19 is swung loosely from a transverse shaft 46 and has its periphery so formed as to lie at different distances from the respective key pins so that the latter will engage the leverto move it a greater or less distance according` to the key operated. The shortest degree of travel ofthe lever 19 is sidiicient to move the hook 45 out of the path of the stud 41 and thus leave the latch-plate 39 free to descend and unlat-ch its respectivev arm 44.

ln machines of the type shown in the present drawings, land in which the cash drawer is released bythe operation of some one of the special keys, it is imperative that means be provided for compelling the operation of the amount keys before a special key. in the present instance this means comprises a curved pivoted lever 48 mounted in proximity to .the lower ends 'of the special key s hank Aso vas to be struck and operated by.

the same. This lever is of bell-crank formav tion, as shown in Fig. J2, and vis pivotally hung upon the shaft 40 and is provided at its forward end with a pin 49. This pin projects into an elongated slot 50 formed in a crank-arm 51 whichis fast to -a transverse rock-shaft 52. This Vshaft carries a looking projection 53, which, when one of the special keys is operated and the shaft rocked, passes in front of all the noses 36 ofthev arms 35 and thus locks all of the detents 34 against operation.

From the above it will be seen that'if a special key isY operated before an amount key,the amount keys will become locked and cannot be operated until that particular' op, eration of the machine is completed. by the opening and closing ofthe cash drawer and the release and return of the special key to its normal position. Should one of the amount keys be .partly operated and an attempt then be made to-release the machine by operating-fone of the special keys, the nose 36 of the detent 34 will occupy such a position as to block the movement of the projection 53 and thus prevent the releasing of the machine by a special key. No special key vcan begoperated unless all of the detents 34 are in their normal positions, and this of course -is not true when any of the amount keys are partly depressed.

The lever 48 `is provided with a rearwardlyextending projection 48a `which coperates with a cam 481 mounted on the rot-ation shaft 77 hereinafter described, whereby the lever 48 is returned to its normal position at the completion of the movement of the" ma chine. Each of the detentel 34 is provided with a trip arm 34b which extends rearwardly into proximity to a series of releasing cams 34c mounted on the rotation shaftv 77 and arranged to `engage said` arms and rock the detentJ to release the keys. The pins 29 of t-he special keys cooperate with a pivoted latch 111 which is pivotallv.

mounted on the lever 48 and is provided with two hook-projections 112, and is formedwith a cam edge 113, (see Fig. 8). When a special key is operated and the lever 48 forced inward, the cam edge 113 engages a stationary transverse shaft or rod 114 and thus forces the plate 111 upward to cause the hooks 112 to engage the respective key pins and lock the keys to the lever 48. By this means any fraudulent operation of the machine, such as a sudden stroke upon the special key to throw the lever 43 inward independently, is prevented.

feas,

A'transverse shaft 115 is provided with a series ot upwardly-extending curved arms 11G which are located in proximity to the pins 29 of the keys ot the amount banks, so that when a key in any one ot the amount lianlrs is operated the shaft 115 Will he rocked. This shaft further carries a rigid arm 117 which is provided iat its `upper end with a stud 118. This stud projects into an elongated notch 119 formed in a pendent arm 120 of a locking lever 121 which is hung upon Vthe shaft 28 and projects forward into proximity to the pins 29 ot' the special keys. The Width otl the forward end of the lever 121 is such that it may hlocl one or the other ot' the special key pins, but not ooth at the same time. lVhen the'parts are in their normal positions, shown in

Figs. \

2 and 8, the forward end ot' the lever 121 lies back of the pin 29 ot the cash key, thus lea ing the no sale key free for operation. lVhen one of the amount keys is operated, however. the lever 121 is rocked through the aforesaid connection and passes out of the pa-thA ot the cash key pin and into the path of the no sale lrey pin, thus releas-V inggthe cash key and locking the no sale key. By this means the machine can not be released hy the no sale key for a cash transaction.

The 'indicating mechanism-Each of the graduated levers 19 is of bell-crank formation and is formed at its rear end with stop nose 5d. This rear end of the lever is provided with a pivoted spring-pressed pawl 55 which is of substantially7 the same shape as the end of the lever and is normally held by the shaft 46 in substantial alinement with the end of the lever proper. Each of the indicators 15, is journaled upon a transverse shaft 57 and is provided with an operating pinion 5S and a star Wheel 58a. Each of the pinions meshes with one of the operating segments 21. These segments'are mounted respectively upon a transverse shaft 59. Each of the segments 21 is formed with a pendent stop arm 61 which contacts with a rigid transverse shaft (32 tor limiting the backward movement ot the indicatorg Each of said segments has 'formed therewith a. step segment 2021 (see Fig. 9), and mounted; loosely upon the shaft 59 beside each of these. segments, is a similar seg` ment 2O which is formed with a nose (33 so located as to contact with the Vunder side ot the segment 21 (see Fig. 10).

From the above construction it will be seen that when the segment 20 is drawn downward. as hereinafter described,v the nose 63 Will cause the rack segment 21 to rock rearward and thus move its respective indicator 15. The downward movement. ot the segment 2O occurs after the stop lever 19 hasheen set, so that afterthe segment 20 and its companion segment 2O2have moved f allow sutcient free play a predetermined distancee the proper step projections thereon will engage simultane- 'ously with the nose 541 and the pawl 1t' the segment 20 alone were arrested by the nose 54, the momentum of the segment 21 would cause the same to overthrow, but as the pawl 55 engages the project-ion ot the sement 2t)a at the saine time that the nose 54 engages the segment 20, the rack 21 is Ipositively arrested. lWhen the segfment 2O is again elevated the nose 54- disengages from the teeth ot the saine While the pawl remains in engagement with the segn'xent 20a, thus locking the indicator in its setposition until it is subsequently locked by its regular retaining paivl. Should one of the indicators stand out of normal position when the machine is subsequently operated, the lever 19 would he set in the usual manner7 hut. as the segment 20' would stand in the path ot' thepawl 55, the latter v-.fould turn on its pivot against the tension of its spring upon striking said segment. Now it' a special key were operated the indicator Would he released in amanner hereinafter described and returned toward normal position, thepawl 55 meanwhile riding over the step projection of the segment 2dl until it assumed its normal position in alinernent with the nose 5d. Each of the indicators is held in its normal position by a coiled spring 60 Which is connected at one end to its segment 21 and at the other to the projection 63 of its respective segment 20. rThese springs are mounted on the shaft 59. The indicator retaining parvis 122 are mounted upon a transverse rock-shaft 123 located above the indicators so that they may he rocked into and out of engagement 'with the star-Wheels 5ta. The shatt 123 is provided atone end witlra pendent arm 124;, in the lowerend of Which is located a spring-pressed plungerp125. This plunger is engaged byv an arm 126 of a pivoted hell-crank lever 127 mounted loosely upon the shaft 62, the lovver end of said lever carries a pin 127 which cooperates with a cam 128 mounted on the rotation shaft 77, whereby the lever is operated to reloclt the indicators at'ter they have heen once released. An arm 129 of the lever 127 is formed with a reduced portion 130 and is arranged to normally rest upon the top of the lever 118, which latter acts as a latch to hold the lever 127 in its locking position. TWhen one ot the special keys is operated and the lever L18 forced inward, as faras the recess 130, lthe lever 127 is released, and rocking forward at its upper end relieves the spring-pressed plunger 125 ot' any pressure and thus permits the indicators to he returned by their springs 60. The ottice ot the spring plunger 125 is to permit the Vindicators to be locked through the cam operation of the lever 127 and still of this latter lever to do away with any ne working points between it and the cam 128. i 'The shaft 123 at one end supports a coiled spring 123% one end of which is secured to the mainframe and the other to the lever 124, whereby said lever when relieved of the pressure of the arm 126 is rocked forward to disengage the 'pawls 122 from the star wheels of the indicators to peri iit the latter to freely return to normal position. lhen the arm 129 descends over the upper end of the lever 118, a shoulder 131 formed thereon passes in front of said lever and thus locks the same in its rear position until the cam 128 again rocks the lever 127 and elevates the arm to clear said lever 48. When the lever t8 has been relieved of the latching lever 127, it is thrown forward into its normal position by its own weight and by theassistance of the drawer plunger spring. Should it for any reason fail toA fully return to its normal position, an arm 48a formed thereon is engaged by a cam 48h on the rotation shaft to effect the desired return.

The registering mechanism-Each of the step segments 20 is connected to its respective pivoted yoke 22 by a pivoted link bar 64, whereby the segment and yoke will move simultaneously. All of the yokes 22 normally rest upon a pivoted lever 16 which is journaled upon the shaft 2S and rests with its lower end upon an anti-friction roller 66 nounted upon the rear wall of the cash drawer 17. When the parts are in the position shown in Fig. 5, it will be seen that the lever 16 is .supportingall of the yokes 22 in their uppermost positions. `When a special key is operated and the cash drawer released, as hereinafter described, said drawer' is forced forward out of its eas-l ing by a suitable coiled springllli) interposed between the drawer and the rear of the casing. As the drawer passes outward the roller 66 passes Vfrom under the lower end of the lever 16 and thus-leaves the lever free to descend as the drawer moves outward. As said lever descends, the yokes 22 which have been previously released by the operation ofthe keys in the amount banks,

as heretofore described, will descend therewith until arrested by their respective step segments 20. lhcn the cash drawer is again closed the roller 66 will engage the inclined forward edge of the lever 16 and force the same rearward and upward, thus elevating all of the yokes 22 and returning them to their normal positions.

Pivotally supported upon the shaft 28 are a series of levers 23 formed with'pendent arms 68 which rest upon the respective yokes, whereby said arms follow the movement of the yokes in descending, but more independently of the same in ascending. Each of said arms is provided with a screw stud 69 which projects into an elongated g slot 70 formed in the rear end of a pivoted and these levers are journaled upon a transshaped frame 7a' journaled upon the shaft 28 and havingvan operating extension 75. This extension is arranged to he engaged by a cam 76 mounted upon a rotation shaft 77 and thus rocked forwardto cause the rack segments 72 to mesh with the counter' pinions 78. YVhen the cam 76 passes free of the arm 7 5 toward the end of the closing` movement of the cash drawer, the frame 74 is drawn back to its normal position to disengage the rack segments from the counter pinions, by coiled springs 79, which connect the respective levers 71 to a transverse shaft 80. after one of the levers 71 has been positioned by the descent of its respective lever 23, it is return-ed to its normal position-by one of a series of vpivoted levers 81 journaled upon the shaft 73 and formed wit-h an operating nose S2 which is arranged to engage the upper' edge of a pawl 83 pivoted upon said lever 71. The forward endof the pawl 83 normally rests upon' a stop pin S4 mounted on the lever 71 (see Fig. 7) so that-when said pawlis lever 71 will be correspondingly moved and returned to its normal position, during` which operation its respective counter wheel will be actuated. The lever 81 at its rear end is provided with an anti-friction roller 85 whiclnis so located as to be engaged and forced forward by one of a' series of cams 86 mountedv in progressive order uporuthe rotation shaft 77 ln order to prevent any pendently of the lever 71, the latter is provided with a hook-projection 87 which extends over the projection 82 so as to contact with the same when it is moved backward independently. Y

lt will be seen from the above description that when the yokes 22 descend and are arrested according to the values of the. keys operated, the levers 23 move correspondingly and thereby set the respective racksegm'ents. When the rotation shaft .77 is now operated, the rack-segments are first. all drawn into engagement. with the counter- Jinions by the rocking forward of the frame The levers 81 are then successively operated and the rach-segr'ients thereby successively returned to their norms positions, thus registering the amount on the counterhave been returned to theirV normal positions, thc cam 76 passes free of the arm 75 and allows the spring 7i? to draw all of the rac'iz-segnients-out of mesh with the counterpini ms. After the. lirst, second or third here is one. of the levers 71 for each of thea-mount banks verse shaft 73 which is mounted in a yoke# `forced .downward by the projection 82, the

excessive movement of the lever S1 vindewheels v13, After all of the rack-segments maar@ 'counter-Wheel has madeY a complete revolution, a pin 88 mounted thereon contacts with .a hooked nose 89 formed 0n ,a segment-al -plate 90 and thus rocks said platevto set the transfer devices, as hereinafter more fully described. As all the plates 90 are similar, I will describe the action of only one as this will suffice for all. y

The plate 90 is pivotally mounted upon a transverse shaft 91 and is `formed in its upper edge with a recess 92 and a cam projection 93. The pawl 83 is provided with a pendent cam nose Qdwvhichnormally projects into the recess 02 forward of the projection 0.3, clearly shown in Fig. 7. 'T he pin 84 on the lever 71 rests normally upon the upper edge of the plate 90 so as to form a positive stop for the segment lever 71I when the same is returned to its normal position. lVhen one of the plates 5)() is rocked forward, however, by' its respective counter wheel pin 88, as before described, the cam projection 93 by its engagement. with the cam nose 94 will force the pawl 83 upward and so change the relative positions of the rack-segment 71 and its operating lever 81 whereby when the latter is operated,.the rack-segment will be moved forward a distance equal to one of its teeth to eiiect the transfer to the counter wheel of the next higher denominaticni. lt willl be understood that the counter wheel pin 88 is mounted on a counter wheel of a denomination lower than the counter wheel controlled by the rack-segment 71 which is governed by said pin. lVhen the plate 90 is rocked forward, the recess 92 is broughtnnder the stud 8l so that lthe rack-segment 71 is left free to make the additional transfer movement. The progressive arrangement of the cams 80 is such that the levers 8l are timed so as to be moved each when a preceding lever has made about half of its stroke. The tripping of plate 00 at times will occur when one of the segments 71 is elevated or is being returned to its normal position, and in this instance the relative change in positions between the respective lever 81 and the rack-segment 71 will not immediately occur, but will be accomplished when the segment has practically reached its normal position, by the cam nose 94 striking the upper end of the projection 93 and thus tending to force the nose Slt upward. As the puwl ut this time, however, is in contact with the `unyi'elding` projection 82, it will move with this projection asa fulcrum and .through its pivotal connection with the, rack-segment 71 will cause it to be advanced the disthnce of one tooth until the stud 84 stri/kes4 the bottom of the recess 92. In ordcr'tohold the plate 00 in its set po- .sition lafter it hasl been once adjusted, I

provide it witha stud 95 which normally rests against a shoulder 100 formed on the outer end of'a pivoted'fle'ver-101 which-is loosely mounted'upongfthe. shaft 28. A coiled spring 102 connects this lever to the pin 95 to normally hold the vparte inthe position shown 'in Fig. lllhenthe segment v910 is rocked forward, as before described, the pin 95 passes clear of a shoulder 10? formed on the lever 101 and thus permits the lever to be drawn downward by its spring 102 until a hook 104 formed thereon contacts with thev pin 95. The rear wall 105 of the hook 104 engages the pin 95 and thereby holds the segment 90 in its set position. The lever 101 is formed near its fulcrum with a shoulder 106 which is so iocated as to be engaged by a cross-bar 107 of the frame 7st when the latter returns to itsl normal position and thus lift said lever 101 and permit the segment S0 to again become set in the positionslmwn in` Fig. The shaft 01 further supports a series of retaining pawls 108 which engage the counter pinions 78 and are hield to their work by flat springs 109 connected thereto and engaging a transverse bar 110. r1`he distance between the pawls 108 and the bar '110 is. such as to prevent any excessive forward throw of the pawls such as might cause said pawls to fail to properly engage the counter pinions and preventoverthrow of the counter wheels. i

The transfers above described relate to the counter wheels ,which are. operated b v theseveral rack levers, but as counters almost necessarily include other wheels, there may be provided any suitable and well-known form of transfer wheels for these latterl counter wheels.

The above describedv counter wheels 18 counter are mounted upon a rotary shaft 175 which 105 formed therein thus picking up their wheels '110 and returning them to their normal' pos'i l tions 1n a manner well knownin the art.

IThe rotation of the shaft is effected by a key 176, shown in Figs. 1 and 12. This key isfbeveled at the end and is provided with a square recess 177 for the reception of the squared end of the shaft, and also with a stop pin 178. An angular arm 17a mounted upon the main frame projects beyond the pin 178 when the turningvto zero operation is commenced, but asthe key continues to rotate, its beveled edge bearing upon a pin 180 mounted on the main frame, gradually forces the key outward so that when the zero position is reached the pin 178 will Contact with vthe arm 174 and thus positively arrest the counter wheels at the zero position. rI he shaft 175 carries a disk 181, shown in Figs. 1 and 11. This disk is formed with a notch 182.

A link bar 183 pivoted on the 130 185 and it will thus be impossible to throw shaft 73 is slotted at its forward end at 184 -outer end of the nested sleeves and shaft 1511 passes from a storage roller -155 mount- -the lever movesfdownward to operate the ratchet 159, jams against om.I of the teeth of upon supporting studs 169 so as to pass beso as to straddle the shaft 175.\ This link is provided with a pin 185 which' normally occupies the position shown in Fig. 11. Then the parts are in the position showninl this figure, the counter is free to be turned to zero, but when the arms 74 are thrown forward to throw in the rack segments, the pin 185 enters the notch 182 and locks the counter shaft. After the rotation of the counter shaft has been commenced the notch 182 will be out of alinement with the pin the segments into mesh with the counter pinions as the arms 74 cannot be thrown forward. y

The printen-Each of the step segments 20 is provided with a pinion 150 which meshes with a corresponding pinion 151 mounted on the inner end of one of a series of nested sleevesl 152, said sleeves being mounted upon a transverse shaft 153 which alsojcari-ies one of the pinions 151. The

above mentioned carry the respective printing segments 18 which are provided upon their peripheries with suitable type representing amounts from 1 to 9.and characters, corresponding to those on the special indicator and the special lreys. The detail strip ed on one of the side-frames, upward and over two guiding pins 156 ,and '157 and down to the winding and feeding roller 158; This latter roller carries a ratchet 159 with whicha pivoted spring-pressed pawl 160 engages for feeding the roller forward to wind the detail strip thereon with a step by step movement. The pawl 160 is mounted upon a platen lever 161 so as to be ref ciprocated once during each operation `of the machine. In order to prevent any overthrow of the feeding roller, the lever 161 is provided witharigid stud 162, which, when said ratchet and therebyprevents any overthrow movement. The lever 161 is journaled on a stud 163 projecting from the side frame and is formed with a shoulder 161 and a curved arm 165. A. cam 166 mounted on the rotation shaft 77 is arrangedto engage the arm 165 and the shoulderil'/t and. thus force the flexible platen 167 carried by the platen lever 161, upward against the detail strip and then downward away from the same. An endless ribbon 168 is mounted tween the detail strip 154 and the printing segments. Any suitable means may be provided for feeding the strip forward upon the operation of the machine so as to bring a fresh inked portion into printing position.

The printing` ribbon 168 is fed forward by a cam arm 168 mounted on the end of the i svago?? the shaft 77 in its normalposition and to also arrest it positively after it has made a complete revolution, the lever 127 (Fig. 2) is formed with a rearwardly-extending'arm 132 having a hook end 133. This hook normallyY passes to the rear of apin 134 mount ed on the cam 128. -l/Vhe'n the lever48 is operated and the lever 127 released in the manner above described, 4the hook 133 is i elevated clear of the pin 131 and remains so until the cam 128 again rocks said lever 127 as the cash drawer starts to close, when the hook is again moved into the path of the pin to positively arrest the movement of the shaft 77 andprevent any overthrow.`

The aforesaid shaft 77 is given a complete rotation at cach operation of the machine 'through the medium of a pinion 135 (Figs.

3 and 5) mounted loosely upon the shaft 77 and meshing witha raclnsegment 136 which is formed integral with the aforesaid lever 16 so that when the drawerp'asses outward, the lever 16 will be rocked downward and forward, and when the drawer is forced inward, the lever will be forced rearward and forward. )When the segment 136 is rocking rearward the pinion 135 turns idly'on the shaft 77, but when the reverse movement of the segment takes place, the pinion becomes coupled to the shaft and thus imparts a complete rotation to the saine. The connection between the pinion and the shaft may be any desirably formed clutch. but for the salte of illustration l have shown in Fig. 3 a construction which employs two membei-s138 and 139eithcr of which is spring pressed.

The cash drawer is provided on its rear vwall (Fig. 5) with a. retaining plate 143 with which a spring-pressed plunger latch 144 mounted on the base ales to retain the drawer in its closed position (see Fig. 5). This plunger is beveled at its lower end so that When the drawer is closed it will be engaged by the plate 143 and elevated until the plate passes to the rearof the saine. when it lwill spring down into its locking position. This plunger is arranged to be elevated by a pivoted lever I 146 mounted on the plate 145 and engaged at its forward end by an adjusting screw 147 which is mounted in the rear end of the lever 148 fast to the. shaft 52.

From the above it will-be seen that the drawer will be released only when one of the special keysis operated. The drawer is mounted in the main frame or casing. in

any suitable manner so that when released it will be automiitically 'forced out -ot' the same by a coiled springlsf) as bet'ore de scribed.

In `order to compel the full opening and closing movement of the cash drawer without any intermediate retrograde movement, I provide the drawer with a pivoted pendent pawl 17a Fig. l which is arranged to ride over and engage a stationary rack plate 17h mounted on the frame of the machine, as shown in Fig. ai. This construction is old and well known in the art.

lt will ot course be understood that while there has been illustrated one set only ot' indicators, a second or duplicate set can read-- ily be mounted upon the shatt- 57 and be coupled to the indicators l5 so as to indicate properly at theopposite side ot the machine. The invention is not limited to the use ot' two keys only in the special key bank as a full set ot keys could readily be used without departing trom the spirit ot this invention; the connections ot the special key bank as tar as indicators and printing devices are concerned being substantially the same as amount banks.

While the torni of mechanism herein shown and described is admirably adapted to tnliill the objects primarily stated. it to be understood that it is not intended to coniine the invention to the one torni ot embodiment herein disclosed, tor it is susceptible of embodiment in various forms all coming within the scope ot the claims which follow.
