DAVID PALMER, OF LOS ANGELES, CALIFORNIA.
ELECTRIC OSCILLATOR.
Specification of Letters Patent.
Patented May 26, 1914.1
' Application filed June 24,1913. Seria1 No.775,554.
To all whom it may concern I Be it known that I, DAvm M. PALMER, a
- citizen of the United States, residing at Los Angeles, in the count of Los Angeles and State of California, ave invented a new and useful Electric Oscillator, of which the following is a specification.
This invention relates to an electric oscillator especially designed for operating asemaphore signal, and the main ob ects of the invention are to provide an electr1c oscillator in which the oscillations are produced by magnets, and the circuits through,
the magnets are controlled byv mechanism of simple and economical construction and of great durability.
Referring to the drawings: Figure 1 1s a front elevation of the device as embodied ina complete signal. Fig. 2 is a-section on line as -w, Fig. 3. Fig. '3 is a plan view.
Fig. 4 is a sectionon line If-w, Fig. 3.
Fig. 5 is asection online a' -w, Fig. 3.
Fig. 6 is'a diagram of the ,wiring. Fig. 7 is an enlarged side elevation with the cover removed, partof the device being in section. Fig. 8 is an enlar ed view, similar to Fig. 5, showing one position of the parts. F1 9 is a view similar to Fig. 8, showing anot er osition of the parts. Fig. 10 is a view simiar to Fig. 8, showing another position of the parts. 4
.The oscillator comprises two pairs of magnets 1 and 2, mounted on a base 3. The magnets 1 are adapted to attract an armaas ture--end the magnets 2 are adapted to attract an armature 5, the armatures 1 and 5 being carried on a walking-beam 6 which is secured to the u per end of'a post 7 rigidly secured to a sha 8, shaft 8 belng journaled in bearings 9. Springs 10 are arranged in the ends of cores 11 of the magnets to act as buffers to prevent shock to the mechanism at the extreme positionsof. stroke of the armature' The circuit through each pair of magnets is controlled,by a switch consisting'of a relatively stationary1 contact 12 and'a movable contact 13. T c contact 12 comprises a plunger which is mounted in a socket 14 and 1s yieldingly supported by a compressionsprin 15. The movable contact 13 comprises a unger mounted within a socket 16 and yielgingl supported by a compression spring 17 an having a stem 18' which projects up from the socket I16 and enables the plunger-to be depressed by a rock arm .19
:which are adjusting screws 30. The rock arm 19 is moved into either ofits positions by movements of cross bar 29 transmitted ithrough screws 30 to the rock arm 19 and Qthere is a sufiicient lost motion between the screws 30 and rock arm 19 to allow the rock arm 19 to remain in either of positions (until the cross bar 29 has nearly reached :the end of its stroke, at which time one of across the ball 25 and t e en the screws 30 contacts with rock arm 19 and moves it down, swingin the rejection 24 V of the rock arm 19 which is depressed, operates to depress the corresponding switch plunger 13 i and bring it into connection with the lower 5 plunger 12, thus closing the circuit through the pair of magnets which are in circuit ;therewith. The pair'of magnets which are thus energized attract their armature and ;sw1ng the cross bar 29in a corresponding direction, thereby rocking the shaft 8 respring 34' which acts to versely. This movement continues until the screw 30 strikes the rock arm 19 and tilts the latter into its opposite position, thereby depressing the other switch plum ger 13 and closing the circuit through the other set of magnets,'whereupon the. shaft 8 is tilted in-a reverse direction bya reverse 1 operation of the parts as, previously described. Thls results in imparting an oscillatory movement to the shaft 8. This movement may be HtIliZE/Id in various ways,
forex-ample, a'semaphore 31 mayb'e mounted. on an arm 32 whichis secured to the shaft 8 and a counterbalancing weight- 33fm'ay be secured tothejower'end of shaft 8 by a a shock at the extreme o secured to arm 32.0naccount of the momen-' tum of the weight 33; Also anelectric light. 35 may be carried'by an arm 3 projectingfrom the shaft 8 which will oscillate-with the semaphore and be visibleat' night.
.. The operatingpartsof the device may be fprevent too sharp" movement which "would 000111 the 33' 'were may also be employed and causedto ring whenever the device is in operation, but
, these features form no part of the invention.
The device may be electrically connected as indicated inFig. 6, the movable plungers 13 being connected by wires 39 and 40 with one side ofthe main' circuit 4L1 which may comprise a part of the railroad track or extend'therealong and be closed in any desired mannerby a car'when the car is at a delinite point. 'The stationary terminals 12 may be connected by wires 42 and 43 with magnets 1 and 2 respectively and magnets 1 and 2 connected by wires 44 and 45 with the other side of the main circuit 46.
What I claim is: 1. Oppositely arranged magnets, an oscillating armature adapted to be attracted by said magnets, a switch in connection with one magnet, a switch in connection with the other magnet, a main circuit with which 'each of said switches is connected, a rock arm pivoted independently-of said oscillating' armature, and adapted to alternately close said switches, and means associated with said armature for pivotall-y rocking said rock arm by the movement of the armature allowing an independent movement ofthe armature for a large part of its stroke without tilting the rock arm.
2. Oppositely arranged magnets, a pair of oscillating armatures adapted to be respectively attracted by said magnets, a switch in connection with one magnet, a switch in connection with the other magnet, a main circuit with which each of said switches is connected, a rock arm pivoted independently of said oscillating armatures and adapted to alternately close said switches, means ,associatcd with said armatures for moving against said rock arm to positively rock the same, allowing an independent movement of the armatures for a large part of their stroke without tilting the rock arm, and an oscillatory shaft supporting said armatures, said rock arm being pivoted at a point above said shaft. a
