of the indicating plates to the initial or neu tral position by action of the spring 22, the pawl plate 23 is extended adjacent the sleeve 20 and said sleeve carries a lug 27 engageable 5 with the pawl to rock it to releasing posi tion upon rotation of the sleeve 20 in a re verse direction due to movement of the rack bar 16 by the releasing magnet 19. To simul taneously shift the sleeve 20 on the shaft to O release its clutch engagement therewith through the fixed sleeve 21, a pair of up standing fingers 28 are provided on the base plate at the sides of the sleeve and the upper ends of these fingers are provided with cam 15. surfaces which coact with the cam surfaces of lugs 29 carried by the sleeve whereby to cam the sleeve outwardly, it being noted that these coacting cam members move apart in the actuating rotation of the sleeve 20, and 20 that in such rotation the lug 27 moves away from the pawl. The sleeve 20 is normally urged to clutching engagement by a spring 30 bearing thereagainst and against the ad jacent shaft bearing 6 and the rack bar 16 25 and consequently the sleeve by reason of the meshing engagement of its teeth therewith is normally urged to an initial position for actuation by either of the magnets, by a spring 31 disposed in the chamber 14 and 30 engageable by depending arms 32 of the rack bar upon shifting movement of the rack bar, the chamber 14 being provided with reduced extensions into which arms 32 may move when not in compressing engagement with 35 the Spring, and said reductions forming con sequent spring seating shoulders. Buffer pads 33 are also carried in said end exten sions of the chamber to cushion the rack bar in its magnet caused movement. 40 When the shaft 7 is released by retracting the sleeve 20, its rotative movement under action of the spring 22 is limited by a lateral stop pin 34 thereon engageable with a buffer 35 carried on the base plate, to thus stop 45 shifting movement of the plates in an initial or neutral position. The present embodiment of my invention is particularly adapted as an indicating unit a voting machine, and each of the indi 50 of cating plates carry the symbols Y, N, and P. indicating the vote “yes,” “no,” or “paired.’ The rear indicating plate is adapted to be photographed in common with other indi cating plates of the machine to form a per 55 manent record of the votes, and the frontin dicating plate 9 in addition to the different symbols described is adapted to display light symbols corresponding to said different sym bols. To accomplish this differential light 60. symbol function with the aid of a single lamp which may be kept continuously light ed during the operation of the machine, the plate 9 is relatively elongated and is pro vided with a series of apertures.covered by different colored light screens 36 correspond

ing to the different vote symbols. Carried on the base plate in such manner that its mouth is obscured when the indicating plate 9 is in initial position, is an open mouth hood 37 into which is disposed a lamp 38. 70 Thus upon successive shifting movements of the plate 9, the apertures 36thereof may be successively lighted by disposition before the mouth of the hood. Although forming no part of my present 75 invention, I have shown the usual total vote controlling switch associated with the pres ent voting indicator embodiment of my in vention, this switch comprising a drum 39 fixed on one end portion of the shaft 7 and 80 carrying contact blocks 40 adapted to close

circuits between pairs of contact fingers 41 Ed on a block 42 upstanding on the base plate.

While I have shown and described a pre 85 ferred embodiment of my invention, it is ob vious that to adapt the invention for specific different uses, and for use under different conditions, various changes and modifica tions of structure may be resorted to without 90 departing in any manner from the spirit of my invention.

I claim: 1. An indicator of the class described com

prising a pair of sliding members having similar indicating symbols thereon, means for simultaneously advancing the sliding members predetermined distances to selec tively display the same symbols thereon, means independent of the advancing means for retaining both of said sliding members in any of their advanced positions, and means for returning the members to normal position. 2. An indicator of the class described com prising a supporting base, a shaft journaled in said supporting base, a symbol carrying member disposed adjacent one end of said shaft and movable transversely thereof, means mounted upon said shaft and engag ing said movable member, and means engag ing said shaft for advancing the movable member step by step whereby to display the desired symbol carried thereby. 3. A device of the character described comprising a supporting base having a shaft journaled therein, a sliding indicating mem ber connected with one end of said shaft, magnetic means for partially rotating said shaft in one direction whereby to move the sliding members, means for retaining the shaft in its rotated position, and a second magnetic coil adapted to return said shaft to normal position. r; 4. A device of the class described com

prising a supporting base, a stationary lamp On Said base, an indicating member having a plurality of indicating symbols thereon, said member also having a plurality of openings therein, each of said openings corresponding
