Frank Adam Electric Co., decided by the United States District Court for the Eastern District of Missouri. and the fact that in the Circuit Master construction the bimetal does not reasonably engage the switch arm and provide a pivot point therefor as in the Swingle [DF NOTE: I do NOT recommend this obsolete publication, though it was cited in the original. Product information . When the handle is turned back to the starting position, the contacts are opened, with the floating lever pivoting about the same point. The record contains stipulated testimony which seems to establish prior public uses of panel boards containing circuit breakers in the Glassow residence in Minneapolis, Minnesota, and in the Pittsfield Building in Chicago, Illinois, in which central, side, top and bottom spaces are provided in the panel boxes between and around the circuit breakers in which air or gas could circulate. Built to deliver safety, reliability and quality. . Fastened to the inside of the casing are longitudinally extending bars on which are mounted the circuit breakers in two rows. Co. v. Pangborn Corp., 4 Cir., 186 F.2d 230, 235, 236.' We are convinced by the record that Multi-breaker bears only scant resemblance to the teachings of Hodgkins. QO load centers are tested and listed only for QO circuit breakers. 1,494,221, dated May 13, 1924, Ellis No. 100 Amp Load Center for sale | eBay "How to plan and install electric wiring for homes, farms, garages, shops," Montgomery Ward Co., 83-850. A licensed electrician can, however, remove the panel face to expose thje panel bus construction to compare the neutral bus locations given in the procedure below. If construed to require only one spring for both manual and overload operation, they are invalid for failure to describe an operable combination in the Swingle specification, and as claiming more than Swingle invented and disclosed. . The Jennings panelboard uses a metal housing, comprising a bottom wall, side walls, and end walls forming a box-like structure. The Jennings Patent No. Compare $ 87 42. 2. . Thus neither Pushmatic nor Circuit Master teach that the floating bar of Hodgkins must move relative to the handle and to the movable contact under all operating conditions, and must have releasable engagement with the bimetallic element. Below note the location of the neutral bus vis-a-vis the Eaton CH Westinghouse electrical panel instructions excerpted above in this article. .

Eaton CH has produced the document cited above, as of Feb 2013, to help identify Westinghouse panels for which Eaton sells replacement components or "renewal parts". The spring then causes the contact arm to follow and carry the movable contact to open position. . . 2,190,517 asserted to be infringed by defendant are directed to the combination of circuit breaker mechanism broadly stated and a casing having means for receiving the mechanism, and are invalid for want of invention over the prior art represented by the above designated prior patents to Weber, DeReamer, Ellis, Gaynor, Laganke, and Aichele.' Photo: a Westinghouse Electrical Panel data label identifying the model as CAT. 23 We append the holdings of the District Judge as to this patent: 24 '6. A spring, extending between a collar on the base and a flange on the member, tends to move this member and the contact to the open-circuit position. 18 As thus interpreted, the only important improvement disclosed by this patent is the construction of two special conduits, between the rows of circuit breakers, formed by the continuous barrier, for the escape of arc gases.

The contention of Westinghouse that its commercially successful Quicklag breaker is made under this patent, seems, at best, only partially true. 1,789,183, dated January 13, 1931. ABB has been named toForbes list of top 30 employersin Canada four consecutive years in a row (2017, 2018, 2019, 2020). The arm, bimetallic element and flexible conductor, connecting the bimetal to a second terminal, are all fixedly secured together prior to mounting them in the casing. One important problem in a circuit breaker panelboard is to get the arc gases, generated during the interruption of a short circuit, out of the space between the contacts without conductive particles being deposited on the walls adjacent the contacts, so that the device will maintain high dielectric strength and be able to operate successively, which is not required of fuses. Thus, in Circuit Master, we find no pins in the casing for slidably receiving the switch arm; this switch arm is mounted in, and carried by the handle; the handle is pivoted with a boss on each side.

InspectAPedia tolerates no conflicts of interest. 49 Upon the passage of overload currents through the breaker, the bimetal element releases the operating lever, permitting independent movement of the contact arm under the influence of its spring to automatically open the circuit entirely free of the handle. 1,732,295, dated October 22, 1929, DeReamer No. . .19, Replacement panelboard trim clamps . The Hodgkins patent must, therefore, be declared invalid. 9 In panelboards having switches and fuses, there is no problem of safely dissipating arc gases given off during the interruption of short circuits. Thus the device may be used as a switch by manually rotating the handle. . Should you have any inquiries related to ABB products and services, or for previously purchased GE Industrial Solutions products, do not hesitate to contact us. In the closed position of the breaker, the operating spring reacts between the handle and operating lever, and holds the contacts in engagement through the latched bimetal element against the bias of the second operating spring.

On manual circuit opening, the spring itself produces the maximum contact separation determined by the extent of the guide slot for the pin, because the line of action of the spring moves to a point well above the pivot point on the bimetal. . Critical information used to identify the specific Westinghouse electrical panel includes: Type of service (phase/number of wires). . Westinghouse Electric & Mfg. 50 What has been previously said as to the Hodgkins patent seems even truer as to the Jennings patent. We agree with the District Judge that this is in no sense a pioneer patent and that its claims and specifications must be narrowly construed and limited to the specific device therein disclosed. Above: a Westinghouse electrical panel from a 1989 home in Lahaina, Hawaii, USA. 1,726,233, dated October 27, 1929, which discloses all functions of the overcenter spring alleged to be novel in Swingle, and the fact that the circuit breakers described in the specification and disclosed in the drawings of the Swingle patent do not suggest the construction of Circuit Master and have attained no commercial use or importance, the Swingle Patent No. Were proud of the recent accolades weve earned Click hereto learn more. . View cart for details. 52 The District Judge pointed out a number of differences between Jennings and Circuit Master and Pushmatic. 71 On the question of whether Swingle was infringed by Circuit Master, the District Judge stated: 72 'In view of the fact that the Circuit Master construction and arrangement of parts is substantially different from that of the construction described in the specification and shown in the drawings of the Swingle patent which do not suggest the Circuit Master construction, the fact that the Circuit Master construction and arrangement of parts resembles that of the prior patent to Laganke No. 37 The structure of Hodgkins follows generally the form of the ordinary screw-type fuse plug. This panel does not appear to be one of the series discussed by the Eaton Westinghouse panel identification procedure given below. . 1,073,103, claims 31, 32, 33 and 44 are invalid in view of the prior patent to Krantz No. The housing of Circuit Master has no means for pivotally mounting the switch arm, or for supporting and defining the movement of the switch arm separately from the handle. You will not receive a notification when a response to your question has been posted. 59 In the Swingle patent, the movable contact is mounted directly and rigidly on an actuating lever, which is a floating lever because it has no fixed pivot. * * * The facts are that these claims were held invalid in June, 1944, in the Westinghouse v.
