"My invention relates to an improved construction of the armature, which I provide with a surrounding soft-iron jacket. This jacket not only serves as a means for attaching the armature to its shafts by a pair of heads or spiders, but it also serves to produce a uniformity in the magnetic flux that passes through the armature." The only mentions of the assignee that we can find are in relation to this patent. Since we have seen this patent date on a GE induction motor and this is the only electric-motor patent issued on this date, we assume that GE bought out the assignee before they had a chance to begin manufacturing the motor. |

Series Parallel Controller
|
William B. Potter |
Schenectady, Schenectady County, NY |
This patent was incorporated into Streetcar motor controllers.
Abstract:
The present invention has for one of its objects to reduce the vertical height of the resistance-switch cylinder, at the same time maintaining the necessary insulation between the contacts thereon. This feature of the invention is accomplished by providing two sets of stationary brushes or contact devices adapted to engage with the contacts carried by the resistance-switch cylinder. The brushes are located, preferably, at points diametrically opposite and, as the cylinder reciprocates, are adapted to engage therewith and vary the resistance of the motor-circuit.
Claim:
In a controller, the combination of a cylindrical switch, contacts thereon, and sets of stationary brushes engaging therewith, the brushes and contacts bearing such a relation to each other that the circuit is alternately completed or broken at one set, then at another.

Double Acting Tool for Planers and Shapers
|
John Riddell |
Schenectady, NY |
My invention relates to double-acting tools for metalworking machinery, such as planers, shapers, etc., and has for its object to provide a simple double-acting tool, which may be readily connected to or disconnected from the ordinary forms of planers and shapers. Double-acting tools, or tools which cut upon both the forward and the return strokes, are used only for roughing out purposes, and must accordingly be replaced by a single-acting tool to finish each set-up of work and be reinserted again for each new set-up, and on account of the difficulty and the time consumed in making these changes in devices of this kind, as heretofore constructed, they have been used but rarely upon the larger planers and practically never upon small planers and shapers. My invention consists of a tool-holder provided with, a shank adapted to be held in operative position by the ordinary tool post of a planer or shaper head, the only changes required to adapt the ordinary planer or shaper for use thereof consisting in the provision of an attachment for reversing the position of the tool and a catch to hold the apron from outward movement upon the back stroke. |

Controlling-Switch
|
Harold E. White |
Schenectady, Schenectady County, NY |
This patent was incorporated into Streetcar motor controllers.
Abstract:
My invention relates to controlling switches employing blowout magnets and is particularly applicable to motor controllers.
It is frequently desirable that the arc formed at each contact-finger should always be blown in the same direction, and since the current through the contact-fingers may be reversed in different positions of the switch, it has been proposed heretofore, in order to secure the desired result, to provide individual blowout coils for each of the fingers, each of which is connected directly in series with its finger, so that when the direction of current through the finger reverses, the direction of current through the blowout coil will also be reversed. When individual blowouts are employed it may sometimes happen that adjacent coils may have a difference of voltage equal to the entire voltage of the system and consequently it is necessary to provide insulation adapted to withstand this voltage. To secure in a compact structure both an efficient magnetic circuit and the necessary insulation so disposed as to permit unobstructed movement to the expanding arc, presents problems, which it is the object of my invention to solve.
My invention in one aspect consists in separating the main poles of the blowout coils from the coils themselves by insulation and providing auxiliary pole-pieces for inductively magnetizing the main poles. By the use of these auxiliary pole-pieces an efficient magnetic circuit may be secured, while at the same time the insulation between each coil and its main pole-piece serves effectively to insulate adjacent blowout coils from each other.
Claim:
In a controlling switch, in combination with a rotary drum and contact-fingers engaging therewith. individual blow-out coils connected directly in series with the several fingers, auxiliary pule-pieces in magnetic contact with the cores of said coils, and main pole-pieces separated from the auxiliary pole- pieces by insulation and magnetized inductively thereby. |

This patent date was seen on a GE type SCR repulsion induction motor from the late 1920s; it has also been seen on a type KT three-phase 1/2 HP induction motor. The patent covers a method of casting squirrel-cage motor cores, and "consists in pouring molten metal into a mold surrounding the magnetic core of an induction motor and simultaneously rotating the mold and core at sufficient speed to drive the molten metal into the conductor receiving openings in the core by centrifugal force, and continuing the rotation until the poured metal has congealed..." |

Electric motor
|
Michael von Dolivo-Dobrowolsky |
, Germany |
This motor is intended to drive a clock, but it is not a true synchronous motor, but rather it is a DC motor with a generator portion that provides a force to counter any change in speed due to voltage fluctuations. Dolivo-Dobrowolsky, a Polish-Russian who had lived in Germany for years, left for Switzerland with the outbreak of World War I. He became a Swiss citizen but had apparently returned to Germany by the time this patent was issued. He died of a heart ailment in 1919, age 57. His lack of strong association with a single country is perhaps part of the reason he is not more famous: no country has chosen to promote him as the pivotal electrical innovator that he was. |

Control for Turret Lathes and the Like
|
Edwin J. Murphy |
Schenectady, NY |
Albert G. Davis - patent attorney
My invention relates to the control of electric motors and has for its object the provision of means whereby the speed of an electric motor may be varied in accordance with the work to be done in a reliable, simple and efficient manner. My invention relates more specifically to the control of electric motors employed for driving machine tools and the like. In the operation of machine tools such as turret lathes, screw machines, and similar machines, it is very desirable that different speeds be given to the motor to correspond to the different classes of work to be done. For instance, the first operation of a turret lathe may be "drilling," the next "tapping" and the next "facing," etc., each of which requires a different cutting speed from the other. The turret may carry as many as 6 or 7 cutting tools and they may each require a different cutting speed so that there will be 6 or 7 speeds for the motor corresponding to the 6 or 7 different positions of the turret. This has been accomplished heretofore by having a controller which is rotated when the turret is turned so as to vary the motor's speed. In this case each position of the controller corresponds to a definite speed on the motor, that is, there is a definite speed for each tool in the turret. It is desirable, however, for each tool to be given a range of speeds so that when a tool is in working position it may have any required speed. An attempt has been made to accomplish this by the use of cams, one for each job, each cam having the proper cam surface to shift the controller the required amount. This involves an unwarranted expense in the making of cams especially in the shops where all kinds of work are done and any machine is liable to be changed from one class of work to another of quite a different character. |

"My invention... has for its object a novel construction of one of the members of such a machine whereby the magnetic material of the member is used to better advantage than was heretofore possible and the available space for the winding of the member is materially increased. Although my invention is applicable to dynamo electric machines generally, it is particularly applicable to single phase alternating current motors of the induction type provided with starting windings. A motor of this type has a nearly uniform revolving field, so that for best operation its field should present a uniform magnetic permeance for each unit element of the air gap periphery (represented usually by a tooth, where the teeth are equiangularly spaced). However, the main running winding is concentric with a larger number of turns in the outside than in the inside coils of each pole, and the starting winding requires only a very small area, part of which is arranged in slots left unfilled by the main winding. The slot area required is therefore not uniformly distributed around the periphery. Such a motor therefore requires a uniform distribution of peripheral iron cross section and a non-uniformly distributed winding... I shape the slots so that their area is such as to be filled with the winding and at the same time preserve a substantially uniform magnetic permeance." This patent date was seen on a GE model 26136 motor, which is a 147 frame, quarter horsepower induction motor with the power applied to the rotor, (the usual induction motor has power applied to the stator, not the rotor) via brushes and slip rings. In a 1930 GE catalog it says, "The Type SA motors are designed with the primary or field winding on the revolving member of the rotor." |

Abstract:
A cutting tool of the type having a recess or pocket at one axial end thereof in which a disposable cemented carbide cutting insert is held by an overhead clamp which also acts to pull the insert back into the pocket. A separate chip breaker plate is releasably attached to the clamp. The means for attachment of the chip breaker plate to the clamp extends through the chip breaker to the clamp and contains a projection below the chip breaker plate which fits within the hole in the insert, so that tightening of the clamp pulls the insert simultaneously toward the shoulder and the base of the recess to firmly clamp the insert in the recess of the shank. |

Abstract:
In cutting tools employing disposable inserts an indexing shoulder is generally provided on the body of the tool. When exposed to excessive force the shoulder may be damaged and the tool difficult to repair. This invention proposes a replaceable seat which is indexed to the tool, and wherein the seat is provided with an shoulder against which the insert is indexed. In the preferred embodiment the insert is provided with a transverse channel in its seating surface and the seal with a mating land. The arrangement provides for forward and reverse indexing of the insert, and is of particular utility in positive rake and tracer cutting tools. |
