Finished - a Complete patent list of the Beam Design
I’ve done a complete survey of the early Beam style patents. Here for the archives is what I have found:
The parent company is above the Patent Number.
On the Beam Design Machine:
There were
16 Patents
6 Inventors
4 Companies Involved
Of those 16 Patents G.P. Castner holds 10 of them!
In order of filing date:
Patch self patent
1,964,440 -10/27/31- Patch – 210 degree tranny, clutch for agitator engagement
<span style="mso-spacerun: yes;"> </span>Solar Corp
2,513,844<span style="mso-spacerun: yes;"> </span>- 8/14/46 Castner – 1<sup>st</sup> Fluid Drive, 1 point suspension, yoke style support , early snubber plates
Solar
2,513,845 – 8/14/46 Castner – FD slippage calculated at 18%, 1<sup>st</sup> FD claim made, good spin theory, first talk of “current cushion”, table of clutching / load speeds
Solar
2,502,702 – 9/27/46 Castner – “GEM of a Patent ! “ Defines terms : “water-wings” & “Flagging effect” for agitator washers !
Solar
2,623,359 – 4/12/47 Castner – Complete 4 belt machine , FD not mounted on motor, addresses end play and chatter in FD, FD engages spin tub AND agitator
Solar
2,699,682 4/12/47 Castner – 1<sup>st</sup> single motor machine, dip vanes for FD for initial pickup
Solar
2,648,213- 8/12/47 Castner – Jaw Clutch delineated, 4 belt machine, FD wash n spin, but ONE DIRECTION stop n Start motor - NOTE: This patent addresses the current draw of Frigidiare machines- its funny how he states it " For example, and from actual tests with a ten ampere ammeter in the load circuit to the motor, in my machine the starting load as the spinning operation begins may run at about three amperes, "whereas in another machine of well known make, the corresponding starting load will cause the ammeter needle to fly completely off scale" !!
Solar
2,625,244 11/24/47- Castner- HORRID MACHINE ! 1 serpentine belt on 2 belt machine, FD centrally located !
GE
2,646,673- 10/19/49 – McCarty- Hotpoint one point suspension, GE snubber,<span style="mso-spacerun: yes;"> </span>2 motor beam machine,<span style="mso-spacerun: yes;"> </span>Inventors Cited : Clark( bendix & unimatic) Kirby ( apex) , Altorfer ( ABC). This is the machine Ben pointed out was actually built.
Solar
2,699,683- 8/23/52- Castner – Uni-direction clutches, one REVERSIBLE motor
GE
2,687,633 – 10/14/50 – Sharp – Famous GE outer tub seal, Ring Band + 4 legs completely support mechanism so all 4 panels are removeable, Sediment tube patented
GE
2,723,737-11/21/50 - Hammell et al- Hotpoint machine, improved FD relates to McCarty patent
Gambles-Skogmo
