PATENT GEEICE.
CHARLES A. ECK, OF BELLEVILLE, NEW JERSEY.
BRUSH-HOLDER.
SPECIFICATION forming part of Letters Patent No. 740,635, dated October 6, 1903.
Application filed February l2, 1903. Serial No. 143,615. (No model.)
To aZZ whom t may con/cern,.-
Be it known that I, CHARLES A. ECK, a subject of the King of Sweden and Norway, and a resident of Belleville, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Brush- IIolders, of which the following is a specification.
My invention relates to brush-holders for dynamo-electric machines, and has for its object the production of a simple, efficient, and inexpensive device which combines the qualities of supporting the brush properly in position and also of rendering its removal easy.
I shall describe a brush-holder for dynamoelectric machines embodying my invention and afterward point out the novel features in the claims.
In the drawings I have illustrated my invention in a suitable form but changes in construction may of course be made without departing from the spirit of my invention.
In the said drawings, Figure 1 represents an end view of a commutator with one brush and brush-holder embodying my invention shown in position on the framework of the motor. Fig. 2 is a sectional plan view on line :c n; of Fig. 1, showing the brush in operative position. Fig. 3 is a view similar to Fig. 2, showing the brush as it appears when about to be removed from the brush-holder.
Similar characters of reference indicate corresponding parts in the different views.
l indicates a commutator, and 2 the framework of a motor or dynamo-electric machine.
3 indicates the brush-holder, and 4L the brush. The brush-holder is constructed with a cylindrical casing 5 suitably mounted on the framework, as by means of the arms 6, and properly insulated., It is further provided with a guideway 7, embracing the brush on three sides and extending parallel with the casing.
In the casing 5 is a plunger 8, carrying a pin 9, extending out through the slot 10 and transversely of the brush at its rear end.
This pin is bifurcated at its outer end, as shown, and has pivoted at its said end a lever 11, provided with two arms 12 and 13, extending at an acute angle with reference to each other and engaging with the brush on its fourth side and at its rear end. The pivot 14 passes through the lever 11 at the base of the arm 12. A spring 15 presses against the plunger S in the direction of the commutator and in a plane parallel with the plane of the brush, causing the two arms 12 and 13 to press the brush against the commutator and to keep it in position. The lever l1 is provided with suitable means, as the projection 16 and hole 17, for shifting its position.
Normally the spring 15 will exert a wed gin g action, through the two arms 12 and 13, on the brush, as shown in Fig. 2; but when it is desired to remove the brush the lever 11 is manipulated outward, as shown in Fig. 3, whereby the brush will be carried out of the guideway.
Having thus described my invention, what I claim is- '1. The combination with a brush, of a brush-holder comprising a guideway for the brush, a casing extending parallel with the guideway, a spring-actuated plunger in said casing, a pin carried by said plunger extending transversely at the rear end of the brush, and a two-armed lever, pivoted on the pin,
fonholding said brush in position,V and byV means of which it can be removed from the holder.
2. The combination with a brush, of a brush holder comprising a guideway surrounding the brush on three sides, a casing extending parallel with the guideway, a spring-actuated plunger in said casing, a' pin lcarried by said plunger extending transversely at the rear end of the brush, a lever, pivoted on 'the pin, having two arms one of which engages with the fourth side of the brush, and the other of which engageswith the rear end of the brush, the arrangement of the parts being such that the spring-actuated plunger will normally cause the two arms to press against the brush to hold it in position, while the arm engaging with the end of the brush will remove the brush, when'manipulated outward.
Signed at Belleville, New Jersey, this 5th day of February, 1903.
l CHARLES A. ECK.

AXEL V. BEEKEN.
