[Music] most foundrymen will recognize this machine as an osborne ramjolt squeeze pin lift molding machine from the sound they will immediately know that this particular machine is equipped with osborne's exclusive and patented ram jolt the hard effective mold ramming mechanism before the introduction of ram jolt osborne engineers concluded that if jolting were possible during the squeeze the effective squeeze could be increased at least 50 percent over the theoretical squeeze based on the squeeze piston alone this one principle was responsible for the development and introduction of the exclusive osborne ram jolt mechanism production models of osborne foundry equipment utilizing ram jolt quickly proved this theory reports from foundries everywhere gave evidence that ram jolt units were providing a steady efficient flow of dense uniform superior quality molds to a proud name that has served the foundry industry for nearly a century was added the first of two features that would keep osborne the leader in the industry to osborne the results of ramjolt were exciting with ramjolt we had achieved mold uniformity density hardness and fidelity to pattern the results were a total acceptance of the principle with one exception noise this was the sound that made ramjolt work metal striking metal we knew we had to project an acceptable noise level in anticipation of rigid environmental standards that were soon to follow our initial objective was to reduce noise to approximately this level this was to be our challenge from this [Laughter] to this and still deliver superior mold quality our engineers began another long-range development program one that would list every possible avenue of research we had to perfect a noise controlled jolt mechanism perfect a noise control jolt mechanism this was the assignment osborne engineers undertook a research program that would last for nearly five years the objective reduce noise levels iron would work the noise wouldn't find a substitute chemical experts were recruited compounds hundreds of them were formulated mixed molded tested and scrapped rubber wood plastics metals combinations laminations thousands of formulas were tried one material worked for the ram insert failed as the strike ring revise the formula and test again reduce noise levels all initial testing was conducted on actual foundry machines in the osborne laboratory a solid steel plate was mounted on the table to simulate mold weight sample inserts and rings were built into osborne stock equipment and the testing began testing that would run for hours days months evaluations calculations measurements endurance widths profiles wear projections involving literally thousands of precision readings on hundreds of samples failures were frequent one material that showed promise on one type of machine would fail on another what was the common denominator why didn't the same material that worked on the ram prove is effective for the anvil jolt ring each failure was cut apart analyzed re-evaluated and changes made in the next formula everything was recorded with cushioned equipment sensitive to a fault highly sophisticated techniques were developed to detect internal force variations adversely affecting the material every test conducted included a total cycle with both an anvil jolt and the ramjolt squeeze action critical factors inventing and cooling the cylinder itself were to be considered initial calculations checking and cross-checking design features compounds heat friction tolerances stress and strain toughness is vital too much is trouble not enough out of the question how far how wide how deep questions like these were asked here and answered gauged by sound meters and more complicated equipment the quest went on the challenge reduce noise levels finally the challenge was met a new name was added to osborne's proud reputation as the leading manufacturer of foundry equipment that name was whisper ram a patented noise control jolt mechanism the research the prototypes the field testings have done their work now osborne equipment with whisper ram moved into reality with heat cold sand impact all in varying degrees incorporated griffith indiana specified two more osborne ram jolt squeeze pin lift machines for a new facility by now whisper ram noise control jolt was standard equipment two model 719 rjw osborne machines were installed one for the drag the other for the cope keemcast immediately endorsed the new noise control feature excellent mold quality improved working environment as more machines were built whisper ram features were installed osborne's famous roto-lift machine was converted the small ramjolt squeezer was next and on it went machine after machine with whisper ram noise controlled jolt the swept the dedication the research was paying off these osborne machines are its stuck casting division of stuffed mold works incorporated lancaster ohio today a single line of 10 osborne machines run side by side day after day making hard dense uniform molds to exacting specifications for both glass mold castings and a wide variety of jobbing work jolt rollover squeeze draw and close molds mechanically using large match plate patterns all of these operations with one operator and one machine the osborne roto-lift seven newer machines include four ramjolt squeezers and three large rotor lifts all with whisper ram components as stuck orders more machines for their expanding needs the call to osborne asks for quote more wisperam machines fe myers company built a new foundry in ashland ohio they too specified osborne machines a pair of model 722 rjw ram jolt squeeze strippers with whisper ram noise control jolt automatic controls include powered movement of the squeeze head and pre-selecting of jolt and squeeze times osborne's exclusive oil control pattern draw stroke guarantees smooth accurate stripping roller stripping frames and roll-on roll-off extensions ease flask and mold handling other than the two machine operators a third man sets cores and assists with the closing of the cope and drag halves this cope and drag setup at fe myers company yields efficient production of larger tight flask molds just another example of the flexibility offered by osborne's line of ramjolt squeeze stripper machines all of this and effective noise control too after nearly five years of research the ideas and testing have done their work they have given us the answers foundries using our equipment offer testimony that the two features giving our equipment distinct advantages over other machines are ram jolt and now whisper ram the first truly effective noise-controlled jolt at osborne we are always abreast of changing requirements for foundry machines several years back we anticipated the need for noise reduction and initiated a program that led to our whisper ram when requirements change for any reason we do something about it the osborne manufacturing corporation of cleveland ohio has served the foundry industry for nearly a century as the leading pioneer and producer of foundry production machinery the background the experience the expertise necessary to design and build quality foundry production machinery to consistently produce high quality castings is the very foundation of the osborne reputation from the outset the osborne creed demanded the highest standards for workmanship for equipment for materials and quality control by placing a high emphasis on standardization osborne stabilizes designs and assures the customer a much greater degree of reliability [Music] a foundryman any foundryman is primarily concerned with one result the end product his product casting a volume of high quality castings out the door osborne is only too aware of this fact it's the motivating force that demands that all of osborne's foundry equipment be built to machine tool standards quality is synonymous with all of osborne foundry products products that include stationary swing head ram jolt squeeze molding machines inliner a total automatic mold production system [Music] automatic cross-loop mold production systems automatic match plate machines rotalift manually operated match plate molding machines ram jolt squeeze stripper pin lift molding machines quick core a complete line of core machines for coal box and hot box production load runners idler rollers and shock guard shock absorbers all familiar osborne trade names and a new member of the osborne line a continuous flaskless horizontal stacked molding machine for vertically parted molds no other company in the world places as much importance on research on finding the answers on the future as does the osborne manufacturing corporation this is a fact what does it mean what does it all add up to one thing quality the finest equipment built the best you
