CUM­MINS HIS­TOR­I­CAL RESTORA­TION CEN­TER

to help carry out the plan. With Gog­gin and Steve San­ders, Wat­son lo­cated a build­ing in which to store it and got it moved in 2012. The col­lec­tion moved again to a larger 10,000 square foot build­ing in 2015. Wat­son re­tired that year but still works at the HRC and is cur­rently lead­ing the restora­tion of the leg­endary 1934 Cum­mins race­cars.

The his­tor­i­cal ar­ti­facts are used by Cum­mins mar­ket­ing in dis­plays at shows, dealer events or new-prod­uct in­tro­duc­tions. The HRC is also used as a train­ing venue for new hires and for catered events for Cum­mins per­son­nel and deal­ers. The HRC vol­un­teers of­ten find them­selves dou­bling as teach­ers, and ed­u­ca­tion both in­side and out­side the com­pany is an­other key fo­cus. In ad­di­tion, the HRC sup­ports car and truck clubs, char­i­ties and lo­cal his­tory or­ga­ni­za­tions.

The Cum­mins His­tor­i­cal Restora­tion Cen­ter is proof that the his­tory of a com­pany, es­pe­cially one as rich and in­dus­try-piv­otal as Cum­mins, is a use­ful cor­po­rate tool that not only ben­e­fits the com­pany but the pub­lic as well.

The col­lec­tion re­cently ac­quired this 1952 NVHIS-1486, a mon­ster­sized, 1,486 cu­bic inch V12. The Nvh-se­ries V12s were in­tro­duced in 1949, re­plac­ing the even more mon­strous VL-12 (4,618 cu­bic inches!), and were dis­con­tin­ued in ’74. Here, re­tired ser­vice en­gi­neer Art Clark and en­gi­neers Ben Schulte (black shirt) and Mike Quar­les check out the in­ter­nal con­di­tion us­ing a borescope. The en­gine pow­ered a backup gen­er­a­tor in a large Rhode Is­land build­ing that was torn down. It had been left out­side for a num­ber of years, so the in­spec­tion is the first step in get­ting this old di­nosaur run­ning again. The base model of this 5,500-pound be­he­moth was rated for 400 max­i­mum horse­power at 2,100 rpm. This su­per­charged ver­sion makes over 600 horse­power at the same rpm us­ing two Cum­mins Twin Disc in­jec­tion pumps.

Clessie Cum­mins be­gan his cor­po­rate jour­ney with one-cylin­der en­gines like these start­ing in 1919. With banker Wil­liam Ir­win back­ing him up, Cum­mins ac­quired a li­cense to build the Hvid en­gine, a 4-stroke oil en­gine in­vented in 1902 by Jan Brons of the Nether­lands. The U.S. pa­tent was owned by Robert Hvid (pro­nounced “Veed”), a trans­planted Dutch­man, so his name was on the U.S. pa­tent. It par­tially meets the cri­te­ria to be called a “diesel” due to a 16:1 com­pres­sion ra­tio, but it doesn’t have a high­pres­sure in­jec­tion sys­tem. Rather, a me­tered amount of fuel es­sen­tially drib­bles into a pre-com­bus­tion cham­ber on the in­take stroke, is va­por­ized by heat and fi­nally ig­nited on the com­pres­sion stroke. This is a 1920 Cum­mins/hvid with a 5-inch bore and a 6-inch stroke, mak­ing 6 horse­power at 550-600 rpm. Ap­prox­i­mately 100 to 125 like it were made. The Cum­mins Hvid en­gines were also built in smaller 1.5and 3-horse­power ver­sions. Many were sold by Sears un­der the Ther­moil name.

This 1942 HBIS-600 is a su­per­charged ver­sion of the leg­endary Model H four-stroke en­gine. It makes 672 cu­bic inches from a 4.875 x 6-inch bore and stroke. It cranked out 200 horse­power at 1,800 rpm and 625 lb-ft at 1,400 rpm via a Cum­mins Sin­gle Disk pump. The “I” in the let­ter des­ig­na­tion in­di­cates an in­dus­trial en­gine, but there were au­to­mo­tive and marine ver­sions as well. In the back­ground is the front half of a 1955 In­ter­na­tional Har­vester R190 truck mount­ing a 1939 HB-6 en­gine. This is one of the ear­li­est H-se­ries en­gines known to ex­ist and the ear­li­est pro­duc­tion H-se­ries en­gine Cum­mins has in the col­lec­tion. Re­cov­ery of this en­gine and truck from a South Dakota farm is a story unto it­self. It’s cur­rently be­ing eval­u­ated to see if it can be brought back to life after 40 years sit­ting in a field.

 In the fore­ground is a Cum­mins ver­ti­cal Hvid en­gine devel­oped for marine use, this one built in 1921. It has a 5-inch bore and a 6-inch stroke for 147 cu­bic inches. Weigh­ing nearly 1,000 pounds, it cranks out a whop­ping 8 horse­power at 600 rpm. A two-cylin­der ver­sion was also built. Only two ver­ti­cal Hvid en­gines are known to sur­vive and Cum­mins has both. In the back­ground is an ex­per­i­men­tal two-stroke en­gine Cum­mins founder Clessie Cum­mins worked on in 1924. Be­hind that is a hor­i­zon­tal Hvid en­gine.
