Yog tias koj khaws cov iav qub txeeg qub tes, koj yuav ntsib tus venerable Hemingray-42 telegraph insulator. Cov qauv no tau lees paub los ntawm ntau yam xim sib txawv, qee qhov tsis tshua muaj thiab muaj txiaj ntsig. Kawm txog keeb kwm ntawm Hemingray-42, nrog rau yuav ua li cas txheeb xyuas ib qho koj yuav pom.
History ntawm Hemingray-42 Insulator
Yog tias koj tau tsav tsheb los ntawm cov xov tooj qub ntawm ib sab ntawm txoj kev tsheb ciav hlau, tej zaum koj yuav pom cov iav insulators ci ntsa iab rau saum tus ncej. Thaum lub sijhawm xov tooj cua yog thawj txoj hauv kev ntawm kev sib txuas lus, cov iav insulators khaws cov xov hlau los ntawm kev sib cuag ncaj qha nrog cov ncej ntub dej. Qhov no tau pab tiv thaiv lub teeb liab thiab tso cai rau nws mus ncig thoob tebchaws. Raws li Hemingray Info, Hemingray-42 yog ib qho ntawm feem ntau hom iav insulators. Ntau lab ntawm lawv tau tsim thaum xyoo 1921 thiab 1960. Txawm tias niaj hnub no, lawv muaj ntau heev nyob rau hauv cov khw muag khoom qub, khw muag khoom, thiab cov chaw muag khoom.
Identifying a Hemingray-42 iav Insulator
Feem ntau, nws yooj yim los txheeb xyuas Hemingray-42 insulator. Cov iav yog embossed nrog lub npe thiab tus lej style; ob qho tib si tau sau meej meej rau ntawm lub insulator. Tej zaum yuav muaj lwm cov cim, suav nrog cov lej, dashes, thiab dots.
Hnub rau Hemingray-42 Insulators
Cov lej thiab lwm yam cim ntawm lub rwb thaiv tsev tuaj yeem pab koj tsim hnub tsim khoom rau nws. Tom qab xyoo 1933, lub tuam txhab pib suav cov cim no los qhia txog hnub tsim khoom. Insulators.info qhia tias koj tuaj yeem pom cov iav Hemingray hauv qab no:
- O - Lub peev O, qee zaum ua yuam kev rau xoom, sawv cev rau Owens, Illinois, qhov chaw tsim hluav taws xob. Cov cim no tau siv nyob rau hauv 1933 thiab tshwm nyob rau hauv lub npe nyob rau hauv pem hauv ntej ntawm lub insulator.
- O-4 (thiab lwm tus lej) - Xyoo 1934, lub tuam txhab pib ntxiv tus lej los sawv cev rau xyoo. O-4 txhais tau tias 1934. O-9 txhais tau tias 1939.
- 23-42 (thiab lwm tus lej) - Xyoo 1940, lub tuam txhab pom tau tias ib tus lej xyoo yuav tsis ua haujlwm ntxiv lawm. Lawv pib ntxiv tus lej pwm thiab ib xyoo tus lej rau sab nraum qab ntawm lub insulator es tsis txhob. Tus lej xyoo yog tus lej thib ob hauv lub teeb, yog li ntawm 23-42, cov pwm insulator tau tsim xyoo 1942.
- Dots - Cov dots uas tshwm nyob ib sab ntawm qee cov hnub qhia tias pes tsawg xyoo dhau los txij li cov pwm tau tsim. Piv txwv li ib qho insulator nrog lub cim 23-42 thiab ob lub dots yuav tau tsim nyob rau hauv 1944.
Hemingray-42 Xim
Koj yuav pom Hemingray insulators hauv ntau xim sib txawv. Cov xim ntau tshaj plaws rau Hemingray-42 insulators yog "Hemingray xiav," ib qho xim ntshiab zoo nkauj uas ntau tus neeg koom nrog iav insulators. Txawm li cas los xij, nws kuj tseem pom lawv nyob hauv aqua, daj ntseg dej khov xiav, ntshiab, thiab lub teeb ntsuab. Cov xim tsis tshua muaj xws li cov xim sib sib zog nqus, ntshiab ntsuab, ruby liab, ob lub suab uas tshwm sim thaum cov xim iav tau hloov, thiab tsis tshua muaj, iridescent carnival iav txheej thiab iav mis.
Insulator Styles
Hemingray-42 insulator tuaj nyob rau hauv ob lub ntsiab. Nyob rau hauv tus qauv style, cov scallops me me los yog "drip ntsiab lus" raws hauv qab ntawm daim tiab yog sib npaug. Nyob rau hauv ib tug rarer variation, lawv yog cov ntsiab lus ntse. Koj yuav pom ob qho tib si ntawm cov khw muag khoom qub.
Hemingray Insulators Tsim Nyog Dab Tsi?
Vim tias Hemingray-42 insulator yog ib qho ntawm ntau tshaj plaws, lawv zoo li cov khoom pheej yig. Feem ntau muag rau qis dua $ 10. Koj yuav pom lawv nyob rau hauv feem ntau cov khoom insulator, tab sis muaj qee yam uas tuaj yeem ua rau lawv muaj nqis me ntsis ntxiv.
Condition
Cov no yog cov khoom qub uas muaj lub hom phiaj siv tau, thiab ntau lub iav insulator tau siv ntau xyoo lossis ntau xyoo nyob sab nraum huab cua. Feem ntau muaj chips, tawg, discoloration, thiab lwm yam kev puas tsuaj. Yog li yog tias koj pom ib qho insulator nyob rau hauv pristine mob, nws yuav tsim nyog ntau dua.
Rarity
Thaum Hemingray xiav zoo nkauj, insulators hauv cov xim no yuav tsis nqa ntau. Yog tias koj muaj Hemingray-42 hauv cov xim tsis tshua muaj, xws li ntsuab ntsuab, nws yuav tsim nyog ntau dua. Mis iav insulators yog qee qhov tseem ceeb tshaj plaws vim lawv qhov tsis tshua muaj.
Sample Values
Txhawm rau muab tus nqi rau ib qho insulator tshwj xeeb, koj yuav tsum tau muab piv rau cov qauv muag tam sim no hauv cov xwm txheej zoo sib xws. Nov yog ob peb tus qauv Hemingray-42 qhov tseem ceeb:
- A ruby liab Hemingray-42 nrog qee qhov hnav rau cov ntsiab lus hauv qab muag ntawm eBay rau yuav luag $80.
- Ib tug aqua Hemingray-42 nrog tag nrho cov ntsiab lus drip zoo muag rau txog $28. Nws muaj ib daim me me ntawm ib sab.
- Ib tug ntshiab Hemingray-42 yam uas tsis muaj tej daim los yog kab nrib pleb tsis tshua ntshaw, muag tau ob las xwb.
Part of Telecommunications History
Yog tias koj tab tom txiav txim siab nthuav koj cov khoom sau lossis tsuas yog txaus siab kawm txog qhov tseem ceeb ntawm keeb kwm kev sib txuas lus, siv sijhawm ib pliag los nyeem txog cov iav antique iav. Muaj ntau ntau hom thiab ntau yam sib txawv thiab xim tawm muaj, ua kom cov insulators muaj kev lom zem thiab pheej yig hobby.
