JOHN imwnnnnrnmonns, or enn'nnwrcn, conunc'rrcu'r, Assmxon 'ro wns'rnnn ELECTRIC coup-m, mconronarnn, or NEW Yonx, N. Y., A conronsrron or New items.

January 5, 1915, wherein the terminals are assembled in a large flatfaced bank or pane'l,-over the faceof which,brush carriers are driven by a continuously moving'm'emher, to which they arecoupled by idler 2y electromagnets. In

rods are positivel restored upon the disestablis hrnent of t e connection, it 'is necessary to providea continuously moving member separate fromthe member used to; drive [the carrier-during the setting'operation.

It is the object ofgthi's i nvention to'provide an arrangementwherein the brushes are driven in both directions by a single continuously moving member.

In accordance with this invention, an electromagnet' is provided which controls an idler roller adapted, when the armature of such magnet is attracted, to force the brush carrierinto engagement with a continuously moving member to drive such carrier in one direction, a second electromagnet being provided with an idler roller adapted, when the armature of such magnet is attracted, to engage both the continuously moving member and the brush carrier, whereb due to the, intermediation of such idler ro ler, the brush carrier is driven'in the opposite direction. 7 Referring. to the drawings, Figure 1 is a side elevat1on,.partially, 1n section, of a.

switch structure embodying this invention;

2- is a section on line2-2 of Fig. 1.

the other to the end of said arm. Brush rod 11 is arrested upon the selected terminals by dee'nergizing magnet 19, and is maintained elevated by a pawl 25, which is pivoted upon a pin 26- mounted in the frame plates 21, 22, this pawl entering perforations in stri 13. The return of the brush rodlIl is efl' oted by energizing magnet 27 the armature 28 of which withdraws pawl 25 from engagement with the perforation in strip 13 and presses the cork-coated idler 29 into engagement with the constantly rotating member 14 and the strip 13. The shaft 14, acting through the idler 29, consequently drives the brush rod 11 downwardly. The circuit of magnet 27 is opened in any suitable manner when the'brush rod reaches its normal position, whereupon spring 46 re tracts the same. The brush-tripping mechanism is shown in detail in Patent 1,123,696

referred to, and need not be described in detail herein,: it being suificient to say that after the brush rod 11 has been elevated a predetermined distance, the magnet 31 is energized, which twists afrod 32,;so that a finger 33 carried thereby is placed in aline- V ment with the lever 34 of the particular set I of brushes it is desired to trip. ther elevation of the brush rod, the lever 34 is de re's'sed by the finger 33, whereupon the mem r 35, carried by such lever, is moved inwardly to allow the brushes'36, 37, 38 and 39 to engage theterminals 40 .41, and-42. The spring43 is "rovided for the pu' of allowing the i itself to any irregularities 'in'th e' surface of the continuously moving member 14. "It

will be noted that thearmature 24' and arm 17 are ivoted upon the same pin, and that .normal y the spring 25 maintains projections 44 on the armature in engagement with the arm 17. As a result of this construction, although the magnet 19 when energized holds the armature 24 against the pole-pieces Upon fur- 3 ioo er. roller'29 to just a idler roller and electromagnetic means adapted to actuate the sameto force said rier having brushes adapted to traverse the same, a continuously-moving member, an

carrier into engagement with said member to drive said carrier in one direction, of a second idler roller-in operative relation to said member and carrier, and electromagnetic means for causing the same to transmlt motion from said member to said carrier to drive the same in the opposite direction.

2. In an" automatic switch, the combination with a row of terminals, a brush car rier having brushes adapted to'traverse thesame, a continuously moving member, an

idler roller and electromagnetic 7 means adapted to actuate the sameto force said carrier into engagement with said member to drive said carrier in one direction, of a second idler roller, and electromagnetic means adapted to cause the same to engage said member and carrier to drive said carrier in the opposite direction.

3. In an automatic switch, the combination with-a row of terminals, a continuously moving member, an idler, a brush carrier between said member and idler and an electromagnet adapted to cause the idler to force said carrier into engagement with said member, of a second idler in operative relation to said member and brush carrier, and an electromagnet adapted to force said idler into contact with said member and carrier.

4. In an automatic switch, a brush carrier and a rotatable member, electromagnetic means adapted to force said carrier into engagement with said member to drive said carrier in one direction, an idler roller in operative relation to the member and carrier, and electromagnetic means for causing the same to transmit motion from said member to said carrier to drive the same in the opposite direction.

In witness whereof, I hereunto subscribe my name this th day of December A. D., 1915.
