Opfindelsen angår en ismaskine af den i krav l's indledning angivne art.The invention relates to an ice machine of the kind specified in the preamble of claim 1.
Der kendes, jf. f.eks. US-patentskrift nr. 4.755.060, 5 ismaskiner af denne art, hvor bundpladen i blandeskålen har et antal åbninger, som samvirker med den roterende kniv til sønderdeling af hårde partikler, f.eks. stykker af frossen frugt, nødder eller bolsjer, der er blevet tilsat selve spiseismassen, inden denne bearbejdes i 10 maskinen. I disse kendte maskiner er åbningerne i bundpladen imidlertid anbragt og strækker sig på en sådan måde, at der dannes "døde ringzoner", hvori knivbladene under deres rotation ikke på noget tidspunkt kommer til samvirke med en åbning. Denne kendsgerning medfører, at 15 ismassen får en længere opholdstid i blandeskålen end strengt nødvendigt, og på grund af den uundgåelige omrøringsvirkning og heraf følgende varmeudvikling bliver ismassen i mange tilfælde opvarmet til en uhensigtsmæssigt høj temperatur.It is known, cf. U.S. Patent No. 4,755,060, 5 ice machines of this kind, wherein the base plate of the mixing bowl has a number of openings which cooperate with the rotating knife for breaking down hard particles, e.g. pieces of frozen fruit, nuts or cobs that have been added to the pulp itself before being processed in the machine. In these known machines, however, the openings in the base plate are arranged and extend in such a way as to form "dead ring zones" in which the blade blades during their rotation do not at any time interact with an opening. This fact causes the ice mass to have a longer residence time in the mixing bowl than is strictly necessary, and because of the inevitable stirring effect and consequent heat generation, the ice mass is in many cases heated to an inappropriately high temperature.
20 Det er opfindelsens formål at anvise udformningen af en ismaskine af den indledningsvis nævnte art, som ikke er behæftet med den ovenfor omtalte ulempe, og dette opnås ved en ismaskine, som ifølge opfindelsen tillige udviser de i krav l's kendetegnende del angivne træk. Ved denne 25 udformning undgås i alt væsentligt de omtalte "døde ringzoner" og den heraf følgende unødvendige omrøring og opvarmning af ismassen, som således kan forlade blandeskålen ved en lavere temperatur, end hvad der hidtil har været anset for muligt.It is an object of the invention to provide the design of an ice maker of the kind mentioned above, which does not suffer from the disadvantage mentioned above, and this is achieved by an ice maker which according to the invention also exhibits the features of claim 1. In this embodiment, the "dead ring zones" referred to are substantially avoided and the consequent unnecessary stirring and heating of the ice mass, which can thus leave the mixing bowl at a lower temperature than previously thought possible.
30 Hensigtsmæssige udførelsesformer for ismaskinen ifølge opfindelsen, hvis virkninger er nærmere forklaret i den efterfølgende specielle del af nærværende beskrivelse, er angivet i krav 2-6.Suitable embodiments of the ice maker according to the invention, the effects of which are explained in more detail in the following special part of this specification, are set out in claims 2-6.

Opfindelsen skal i det følgénde forklares nærmere under henvisning til det på tegningen viste udførelseseksempel på en ismaskine og dele deraf, idet 5 fig. 1 viser ismaskinen set fra siden og med maskindæks-lerne fjernet, fig. 2 viser maskinen set forfra og med maskindækslerne påsat, fig. 3-5 viser blandesneglen og blandeskålen med sidst-10 nævnte i tre forskellige højdeindstillinger, fig. 6 i forstørret målestok viser et snit gennem den nederste del af blandeskålen, dennes bundplade og bundpladens fastgørelsesorgan, fig. 7 set ovenfra og i to forskellige lodrette snit viser 15 blandeskålens bundplade, fig. 8 i forstørret målestok viser blandesneglen set fra siden, og fig. 9 i samme målestok som fig. 8 viser den til blandesneglen hørende kniv til sønderdeling af hårde partikler, 20 set fra siden.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the exemplary embodiment of an ice maker and parts thereof shown in the drawing. 1 is a side view of the ice maker and with the machine covers removed; FIG. 2 is a front view of the machine with the machine covers attached; FIG. 3-5 show the mixing auger and mixing bowl with the latter in three different height settings; 6 is an enlarged sectional view of the lower portion of the mixing bowl, its base plate and the base plate fastener; FIG. 7 is a top view and in two different vertical sections 15 shows the base plate of the mixing bowl; FIG. 8 is an enlarged side view of the mixing auger; and FIG. 9 on the same scale as FIG. Fig. 8 shows the blade of the mixing screw for breaking down hard particles, 20 as seen from the side.
Det på tegningen viste udførelseseksempel på en ismaskine ifølge opfindelsen omfatter som aktive bearbejdningsorganer en tragtformet blandeskål 21, hvis bund, jf. især fig.The exemplary embodiment of an ice machine according to the invention shown in the drawing comprises as active processing means a funnel-shaped mixing bowl 21, the bottom of which, cf.
25 6 og 7, udgøres af en opadtil plan bundplade 21a, hvori der er udformet en åbning 21b, hvorigennem det bearbejdede materiale kan passere, - en under drift roterende blandesnegl 17, hvis ydre kontur passer sammen med indersiden af skålen 21, og 30 som forneden drejefast men aksialforskydeligt bærer en25 and 7 are constituted by an upwardly planar bottom plate 21a, in which an aperture 21b is formed through which the machined material can pass, - an operating rotary mixing auger 17, the outer contour of which matches the inside of the bowl 21, and 30 which lower rotatable but axially displaceable carries one

3 kniv 18, der som vist i fig. 9 i det viste eksempel omfatter fire radialt udragende knivblade 18a, der er indrettet til at samvirke med åbningen 21b i bundpla-5 den 21a, hvilken kniv 18 eventuelt kan være fjederbe lastet i nedadgående retning, en "skålelevator" eller slæde 20, som under glidning på lodrette søjler 19 kan hæves til de i fig. 4 og 5 viste arbejdsstillinger, hvor indersiden af skålen 21 10 befinder sig tæt ved henholdsvis berører ydersiden af vindingerne på sneglen 17, og diverse betjenings-, styre-, driv- og bevægeorganer, hvormed bevægelserne af sneglen 17 og skålen 21 effektueres og styres til opnåelse af de ønskede drifts-15 funktioner.3, knife 18, which as shown in FIG. 9 in the example shown, four radially projecting knife blades 18a arranged to cooperate with the opening 21b in the bottom plate 21a, which knife 18 may optionally be spring loaded downwardly, include a "bowl lift" or carriage 20 which sliding on vertical columns 19 can be raised to those of FIG. 4 and 5, where the inside of the bowl 21 10 is close to, respectively, touches the outside of the turns of the auger 17, and various operating, control, driving and moving means by which the movements of the auger 17 and the bowl 21 are effected and controlled to achieving the desired operational functions.
Skålen 21 kan være permanent fastgjort til slæden 20, men er fortrinsvis udtageligt anbragt og styret i denne på sådan måde, at skålen holdes nøjagtigt koaksialt med sneglen 17. Sneglen 17 kan ligeledes være permanent fast-20 gjort til sin drivaksel 17a, men er fortrinsvis fastgjort til denne ved hjælp af en såkaldt lynkobling 16.The bowl 21 may be permanently attached to the carriage 20, but is preferably removably disposed and guided therein in such a manner that the bowl is held exactly coaxially with the auger 17. The auger 17 may also be permanently attached to its drive shaft 17a, but is preferably attached to this by means of a so-called lightning coupling 16.
Sneglen 17 er fortrinsvis udformet af et ikke helt hårdt plastmateriale. Herved opnås i den i fig. 5 viste arbejdsstilling, at sneglen afstryger materiale bedre fra inder-25 væggen af skålen 21 og derved tømmer skålen mere effektivt, end hvad der har været muligt med de tidligere anvendte metalsnegle. En lignende virkning kan opnås ved at anvende en blandeskål 21 af plastmateriale, og i så fald kan sneglen 17 bestå af metal, men risikoen er her 30 større for afslidning af skålens indervæg og deraf følgende forurening af det bearbejdede materiale.The auger 17 is preferably formed of a not completely hard plastic material. This is achieved in the embodiment of FIG. 5 shows that the auger strips material better from the inner wall of the bowl 21, thereby emptying the bowl more efficiently than was possible with the previously used metal screws. A similar effect can be obtained by using a mixing bowl 21 of plastic material, in which case the auger 17 may consist of metal, but the risk here is greater for the abrasion of the inner wall of the bowl and consequent contamination of the processed material.
Slæden 20 er fastgjort til den ene ende af en lang kæde 4, hvis anden ende som vist er fastgjort til et relativt højt beliggende sted i maskinstellet. Fra slæden 20 forløber 35 kæden 4 først-over et kædehjul 8, der er drejeligt lejretThe carriage 20 is attached to one end of a long chain 4, the other end of which is shown as attached to a relatively high position in the machine frame. From the carriage 20, the chain 4 extends first over a sprocket 8 which is pivotally mounted

4 om en stationær akse i maskinstellet, og derfra ned under et kædehjul 5, der er drejeligt lejret på den bevægelige del af en elektrisk drevet lineær motor, f.eks. en såkaldt 5 spindelmotor 2, der er fastgjort i maskinstellet, for til sidst at ende i sit forankringspunkt på det nævnte højt beliggende sted i maskinstellet. Når den lineære motor 2 aktiveres fra den i fig. 1 viste stilling, bevæges kædehjulet 5 nedad, hvorved slæden 20 med blandeskålen 21 løf-10 tes med den dobbelte hastighed. Under den nedadgående bevægelse passerer og aktiverer kædehjulet eller et hermed forbundet organ et antal kontakter 9-12 på en kontaktbære-plade 13, der er fastgjort i maskinstellet. Kontakten 9, der er anbragt øverst, udgør det øverste endestop for 15 kædehjulet 5, dvs. det nederste endestop for slæden 20 med blandeskålen 21, mens kontakten 12 er det nederste endestop for kædehjulet 5 og dermed det øverste endestop for blandeskålen 21.4 about a stationary axis of the machine frame, and from there down a sprocket 5 pivotally mounted on the movable part of an electrically driven linear motor, e.g. a so-called 5 spindle motor 2, which is fixed in the machine frame, to eventually end in its anchorage point at said high position in the machine frame. When the linear motor 2 is activated from the one shown in FIG. 1, the sprocket 5 is moved downwards, thereby lifting the carriage 20 with the mixing bowl 21 at double speed. During the downward movement, the sprocket or associated member passes and activates a plurality of contacts 9-12 on a contact carrier plate 13 secured in the machine frame. The switch 9 located at the top constitutes the top end stop for the sprocket 5, ie. the lower end stop of the carriage 20 with the mixing bowl 21, while the contact 12 is the lower end stop of the sprocket 5 and thus the upper end stop of the mixing bowl 21.
De mellemliggende kontakter 10 og 11 bevirker under den 20 nedadgående bevægelse af kædehjulet 5, dvs. den opadgående bevægelse af blandeskålen 21, først en igangsætning af sneglen 17, som til dette formål drives af en hovedmotor 1, og derpå en midlertidig standsning af blandeskålens opadgående bevægelse for at give sneglen 17 lejlighed til 25 at blande det i blandeskålen indførte materiale, jf. fig.The intermediate contacts 10 and 11 act during the downward movement of the sprocket 5, i.e. the upward movement of the mixing bowl 21, first a start of the auger 17 driven for this purpose by a main motor 1, and then a temporary stopping of the upward movement of the mixing bowl to give the auger 17 an opportunity to mix the material introduced into the mixing bowl, cf. FIG.
4, inden blandeskålen føres til den endelige uddrivningsstilling, der er vist i fig. 5.4 before moving the mixing bowl to the final expelling position shown in FIG. 5th
I det viste eksempel styres den lineære motor 21 s bevægelige del af en styreskinne 30, der er fastgjort i 30 maskinstellet.In the example shown, the movable portion of the linear motor 21 is controlled by a guide rail 30 secured to the machine frame.
Både hovedmotoren 1 og de forskellige omtalte kontakter 9-12 er fortrinsvis forbundet' med en styreboks 3, der indeholder de fornødne tilslutninger, relæer - herunder eventuelle halvlederorganer - og sikringer, idet styre-35 boksen 3 også er indrettet til at modtage styresignalerBoth the main motor 1 and the various mentioned contacts 9-12 are preferably connected to a control box 3 containing the necessary connections, relays - including any semiconductor means - and fuses, the control box 3 also being arranged to receive control signals.

5 fra et betjeningspanel 22, der er anbragt øverst på maskinens mod højre i fig. 1 vendende forside, og som bl.a. omfatter en netafbryder 23, en startkontakt 24, en 5 fejlmeldingslampe 25, et nødstop 26 og et stop 27. Styreboksen 3 er også indrettet til at afgive melde- eller alarmsignaler, f.eks. til den nævnte fejlmeldingslampe 25 og/eller til en ikke vist alarmklokke eller lignende.5 from a control panel 22 located at the top of the machine to the right in FIG. 1 facing front, and which i.a. comprises a mains switch 23, a start switch 24, a 5 error message lamp 25, an emergency stop 26, and a stop 27. The control box 3 is also arranged to give alarm or alarm signals, e.g. to said error message lamp 25 and / or to an alarm clock or not shown.
Ud over de nævnte organer og funktioner, der vedrører 10 ismaskinens normale drift, er styreboksen 3 også indrettet til at modtage signaler fra en nederst til højre i fig. 2 anbragt skyllekontakt 29 og i afhængighed heraf at iværksætte en skylleoperation, der omfatter, at blandeskålen 21 i sin højeste stilling, hvor den, jf. fig. 5, er i intim 15 berøring med sneglen 17, eller eventuelt i den noget lavere, i fig. 4 viste stilling, lukkes foroven af en lukkeplade 15, hvorpå der gennem et par skyllerør 14 rettes en skyllevandsstrøm gennem blandeskålen, fortrinsvis mens sneglen 17 roterer. Skylleoperationen kan i givet 20 fald efterfølges af en gennemblæsning med varm luft eller damp med henblik på at fjerne de sidste rester af skyllevandet og/eller sterilisere de aktive flader på sneglen 17 og blandeskålen 21.In addition to the said means and functions relating to the normal operation of the ice machine, the control box 3 is also arranged to receive signals from a bottom right in FIG. 2, flushing contact 29 and, as a consequence, initiating a flushing operation which comprises the mixing bowl 21 in its highest position, where it, cf. 5 is in intimate contact with the auger 17, or possibly in the somewhat lower one, in fig. 4 is closed at the top of a closure plate 15, through which a pair of flushing pipes 14 direct a flushing water flow through the mixing bowl, preferably while the auger 17 is rotating. The rinsing operation may be followed by a hot air or steam blow-through in order to remove the last remnants of the rinsing water and / or sterilize the active surfaces of the auger 17 and the mixing bowl 21.
En lynkobling 6 er indrettet til at forbinde ismaskinen 25 med en kilde for skyllevæske, f.eks. det lokale vandværk -selvsagt under forudsætning af, at de hygiejniske bestemmelser overholdes. En kilerem 7 overfører drivkraften fra hovedmotoren 1 til sneglen 17. Den i fig. 2 viste sikkerhedsskærm 28 beskytter personalet mod utilsigtet berøring 30 med sneglen 17 og kniven 18 og er på i øvrigt kendt, men ikke vist måde mekanisk forbundet med en sikkerhedskontakt, der afbryder maskinens drift, når skærmen 28 fjernes.A lightning coupling 6 is arranged to connect the ice maker 25 to a source of rinsing liquid, e.g. the local waterworks - of course, provided the hygienic regulations are observed. A V-belt 7 transfers the driving force from the main motor 1 to the auger 17. The embodiment of FIG. 2, the safety shield 28 shown protects the personnel from accidental contact 30 with the auger 17 and the knife 18 and is otherwise known, but not shown, mechanically connected to a safety switch which interrupts the machine operation when the shield 28 is removed.
Som det fremgår af fig. 6, 7 og 9, er åbningen 21b i 35 bundpladen 21a udformet som en "seksarmet søstjerne", hvisAs shown in FIG. 6, 7 and 9, the opening 21b of the bottom plate 21a is formed as a "six-armed starfish" if
DK 165896 BDK 165896 B
6 enkelte arme når helt ud til det sted, hvor indersiden af skålen 21 går over i oversiden af bundpladen 21a, mens kniven 18 består af fire radialt rettede knivblade 18a, 5 hvis radiale længde- stort set svarer til den radiale udstrækning af de enkelte arme i åbningen 21b.6 individual arms extend all the way to the place where the inside of the bowl 21 goes into the upper surface of the base plate 21a, while the knife 18 consists of four radially directed knife blades 18a, 5 whose radial length broadly corresponds to the radial extent of the individual arms. in the opening 21b.
Ved at de enkelte arme i åbningen 21b og de enkelte knivblade 18a på kniven 18 når i hovedsagen helt ud til indersiden af blandeskålen 21' i dennes nederste del opnås, 10 at hårde partikler, såsom klumper af frossen frugt, nødder og lignende, bliver udsat for en "klippevirkning", så snart de rammer bundpladen 21a, til forskel fra situationen i tidligere kendte maskiner af denne art, hvor åbningerne i bundpladen havde en begrænset radial udstræk-15 ning, således at der opstod "døde ringzoner", hvor knivbladene teoretisk set kunne blive ved med at føre de hårde partikler rundt og rundt på bundpladen, uden at de kom i indgreb med åbningen eller åbningerne i denne. Når det tages i betragtning, at den omrøringsvirkning, som sneglen 20 17 og kniven 18 med sine knivblade 18a bevirker i den i blandeskålen 21 anbragte, ikke viste ismasse, uundgåeligt bevirker en opvarmning af ismassen, vil det være indlysende, at opholdstiden i blandeskålen 21 bør være så kort som muligt. Ved den særlige ' udformning af åbningen 21b, 25 som anvises ifølge opfindelsen, undgås de nævnte "døde ringzoner", idet enhver hård partikel, der rammer oversiden af bundpladen 21a, straks vil blive fanget af det næste knivblad 18a og ført hen til den nærmest i omdrejningsretningen beliggende arm af åbningen 21b, hvor 30 den første "afklipning" af partiklen sker, idet partiklen ved den efterfølgende passage hen over de øvrige arme i åbningen 21b efterhånden vil blive fuldstændigt sønderdelt og følge den øvrige ismasse ned gennem åbningen til dannelse af en profileret "slange", jf. fig. 5.By the individual arms of the opening 21b and the individual knife blades 18a of the knife 18 reaching substantially all the way to the inside of the mixing bowl 21 'in the lower part thereof, 10 hard particles, such as lumps of frozen fruit, nuts and the like, are exposed. for a "cutting effect" as soon as they hit the base plate 21a, unlike the situation in prior art machines of this kind, in which the openings in the base plate had a limited radial extent, resulting in "dead ring zones" where the blade blades theoretically seen, it could continue to carry the hard particles around and around the base plate without interfering with the opening or openings therein. Considering that the stirring effect produced by the auger 20 17 and the knife 18 with its knife blades 18a in the ice mass not shown in the mixing bowl 21 inevitably causes a heating of the ice mass, it will be obvious that the residence time in the mixing bowl 21 should be as short as possible. In the particular design of the aperture 21b, 25 disclosed in the invention, the said "dead ring zones" are avoided, as any hard particle hitting the top of the bottom plate 21a will immediately be trapped by the next knife blade 18a and lead to the nearest in the direction of rotation of the opening 21b, where the first "clipping" of the particle occurs, the particle, upon subsequent passage across the other arms of the opening 21b, will eventually be completely disintegrated and follow the remaining ice mass down through the opening to form a profiled "hose", cf. fig. 5th
35 Som det fremgår af fig. 7 og 9 har kniven 18 et mindre antal, nemlig fire, knivblade 18a end antallet, nemlig35 As can be seen from FIG. 7 and 9, the knife 18 has a smaller number, namely four, blade blades 18a than the number, viz
DK 165896BDK 165896B
7 seks, af arme i åbningen 21b i bundpladen 21a. Herved undgås det, at samtlige knivblade 18a samtidigt samvirker med et tilsvarende antal arme i åbningen 21b, hvad der i 5 værste tilfælde - hårde partikler i indgreb foran samtlige knivblade - ville kunne føre til en meget hård belastning af kniven 18, og i det mindste til kraftige vibrationer, dersom antallet af hårde partikler i ismassen er relativt stort. En lignende virkning ville selvsagt 10 opnås ved at antallet af knivblade var større end antallet af arme i åbningen, men den viste udformning giver bedre styrkeforhold. Ved at antallet af knivblade 18a og antallet af arme i åbningen 21b begge er lige tal opnås, at reaktionskraften på kniven 18 bliver mere symmetrisk 15 end, hvad der ville være tilfældet med et ulige antal knivblade henholdsvis arme i åbningen.7, of arms in the opening 21b of the base plate 21a. This prevents all knife blades 18a from simultaneously cooperating with a corresponding number of arms in the opening 21b, which in 5 worst cases - hard particles engaging in front of all blade blades - could lead to a very heavy load on the knife 18, and at least for strong vibrations if the number of hard particles in the ice mass is relatively large. A similar effect would of course be achieved by the number of blade blades being greater than the number of arms in the opening, but the design shown gives better strength ratios. By the number of knife blades 18a and the number of arms in the opening 21b being both equal numbers, the reaction force on the knife 18 becomes more symmetrical 15 than would be the case with an odd number of knife blades and arms respectively in the opening.
Som det fremgår af snittet til højre i fig. 7, kan sidefladerne 21c og 21d i armene i åbningen 21b forløbe skråt nedad og bort fra hinanden. Dersom sneglen 17 og dermed 20 kniven 18 med knivbladene 18a på "normal" måde roterer med solen, dvs. i urvisernes retning som set ovenfra, vil æggene 18b på knivbladene 18a under disses rotation samvirke med de øverste kanter af sidefladerne 21d på lignende måde som en saks. Det har her vist sig hensigts-25 mæssigt at udforme i det mindste sidefladerne 21d med et skråt forløb som vist, idet overklipningsvirkningen herved forbedres og varmeudviklingen formindskes. Når også de modsatte sideflader 21c forløber skråt på lignende måde, skyldes dette dels hensynet til fremstillingen, idet to 30 modstående arme formes, f.eks. ved udfræsning, på samme tid, dels at det har vist sig, at dette divergerende forløb af sidefladerne, navnlig i samvirke med et tilsvarende divergerende forløb af de enkelte armes endeflader 21e, samt den nedad konvekse udformning af undersiden 21f 35 af bundpladen 21a, giver særdeles fordelagtige udstrømningsforhold for den "slange" af ismasse, som ekstruderes gennem åbningen 21b.As can be seen from the section to the right in FIG. 7, the side faces 21c and 21d of the arms of the opening 21b may extend obliquely downward and away from each other. If the auger 17 and thus the knife 18 with the knife blades 18a rotate in the "normal" manner with the sun, ie. in the clockwise direction as seen from above, the eggs 18b on the knife blades 18a during their rotation will cooperate with the upper edges of the side surfaces 21d in a similar manner to a scissors. Here, it has been found convenient to design at least the side surfaces 21d with an oblique gradient as shown, thereby improving the mowing effect and reducing the heat generation. Also, when the opposite side faces 21c extend obliquely in the same way, this is partly due to the consideration of the fabric, forming two opposing arms, e.g. by milling, at the same time, partly because it has been found that this divergent course of the side faces, in particular in conjunction with a corresponding divergent course of the end faces 21e of the individual arms, as well as the downwardly convex shape of the underside 21f 35 of the base plate 21a, particularly advantageous outflow conditions for the "hose" of ice mass extruded through the aperture 21b.

Bundpladen 21a er fortrinsvis udløseligt fastgjort til undersiden af blandeskålen 21, f.eks. som vist i fig. 6 ved hjælp af en omløbermøtrik 21g.The bottom plate 21a is preferably releasably attached to the underside of the mixing bowl 21, e.g. as shown in FIG. 6 using a nut 21g.
5 Det er på tegningen ikke vist, hvorledes kniven 18 er forbundet med sneglen 17 på en sådan måde, at kniven kan forskydes aksialt, eventuelt under fjederbelastning, i forhold til sneglen, men ikke dreje i forhold til denne.5 It is not shown in the drawing how the knife 18 is connected to the auger 17 in such a way that the knife can be displaced axially, possibly under spring load, relative to the auger, but not rotate relative thereto.
Det ligger imidlertid inden for en faglært mekanikers 10 normale arbejdsområde at finde en til dette formål egnet indbyrdes udformning og anordning af de to organer. En kendt mulighed er allerede antydet i det indledningsvis omtalte US-patentskrift nr. 4.755.060.However, it is within the normal scope of operation of a skilled mechanic 10 to find a suitable design and arrangement of the two members for this purpose. A known possibility is already hinted at in U.S. Pat. No. 4,755,060.
