GEORGES A. DE GUIRE, OF MONTREAL, QUEBEC, CANADA.
ELEGTROMECHANICAL MOTOR.
To all whom it may concern Be it known that I, Gnoncns A. Dn GUIRE, a subject of the King of Great Britain, and a resident of Montreal, Quebec, Canada, (whose post-oflice address is 460 La Salle road, Verdun, Montreal, Quebec, Canada,) have invented new and useful Improvements in Electromechanical Motors, of which the following is a specification.
My invention relates to an electromechanical motor.
The present application is a continuation in part of application Ser. No. 11,652, filed Mar. 1, 1915.
In order to more clearly disclose the construction, operation, and use of my invention, reference should be had to the accompanying drawings forming part of this application. It is here shown as used in ringing a bell. Throughout the several figures of the drawings like reference characters designate the same parts.
In the drawings:
Figure 1 is a diagram, showing the relation of the parts and the connections;
Fig. 2 is an enlarged cross section of the solenoid coils showing the core inside and a front view of the rack;
Fig. 3 is an enlarged side elevation of the tripping mechanism;
Fig. 4 is an enlarged side elevation showing the contacts, the brushes and the flexible lead which carries the current to the brushes;
Fig. 5 is an enlarged cross section on line 5 5 of Fig. 1;
Fig. 6 is a side elevation of one of the coils;
Fig. 7 is an enlarged side elevation of one of the insulation plates between the coils;
Fig. 8 is a cross section on line 88 of Fig. 4;
Fig. 9 is a cross-section of square tube 21 of Fig. 4;
Fig. 10 is a cross section on line 1010 of Fig. 4; and
Fig. 11 is a side View of one of the pins.
Referring to Fig. 1, a square tube 21 is mounted so as to slide through suitable guides 18 secured on frame 47. The. upper portion of square'tube 21 travels through a solenoid B which is composed of a number of coils a to a mounted on a tube 19 and connected in series and spaced by sheets of non-conductive material such as fiber, and
carries a core 20 insulated from the square Specification of Letters Patent. Patented 11, 1919 Application filed. May 9, 1916.
Serial No. 96,437.
This method of connections being continued throughout for a purpose to belater dis closed. 7 I
When the system is in its normal condition, the pawl 25 of the tripping switch is pointing down and lever 26 is raised and the upper end 27 of the sliding rod 39 is hooked to the lower end of armature 45 which keeps contacts 24 closed. If now, this circuit is connected to a suitable source of electric energy 30 and controlling switch 31 is closed, a current will flow therethrough and through two of the coils of the solenoid B.
Referring more particularly to Fig. 1, which represents more diagrammatically the operation of starting a bell in the ordinary manner; the square tube 21 carries two brushes 22 and 23 insulated from square tube 21 by non-conductive material 50. To the brushes 22 and 23 are connected flexible leads 33 and 34 fastened on frame 47 by an insulator 54. When the brushes 22 and 23 are in the normal position, that is as shown in Fig. 1, current flows from positive side of the source of electric energy 30, through conductor 35, conductor 17, contacts 24, conductor 34, brush 23, contact 11, conductor 11, coils a and a, conductor 13% con tact 13, brush 22, conductor 33, switch 31 to negative of the source of electric energy 30. The flow of current through coils a and a produces a magnetic field around these coils. The core 20 is so placed in this field that a maximum pull is exerted upon it by this field. The core 20 moves downward carrying the tube 21 and brushes 22 and 23 with it at the same speed. As the brushes 22 and 23 move downward on to succeeding contacts, the electric current is cut off from coil a and coil a is cut in so that the magnetic field moves in the same direction and at the same rate as the core 20. WVhen brush 22 reaches contact 16, current will flow from positive side of the source of electric energy 30 through conductor 85, conductor 32, magnet 28, conductor 36, contact 16, brush 22, conductor 33, switch 31 to negative of the source of electric energy 30. This causes magnet 28 to attract armature 45 which releases cat ch 27 and the expansion of spring 56 causes pawl 25 to rise and take a hori" zontal position and contacts 2 1 are open, thus stopping the flow of current in the solenoid coils and the pull ceases. The bell 44; on its return swing pulls the core 20and parts connected to it upward. During this movement the pin 40 which is the top one in the square tube 27 slides past the'pawl 25 which is raised and kept at rest against thepressure of a light spring 37. Vihen the downward swing again begins, one of the pins 40 engages pawl. 25 which raises lever 26, engages catch 27 to catch of armature a5, and contacts 2% are closed. It will be noticed that the catches are made on a bevel. This is to allow the spring 38 to force rod 7 39 to raise lever 26 so that pawl 25 will clear the pins lO on the downward motion. Coils are then energlzed and a downward pull 1s exerted on the core 20 again until brush. 22
reaches contact 16 as before described. This cycle of motions will continue-as long as current is supplied.
The operation of the tripping switch may be more clearly understood by reference to Fig. 3, which shows the tripping switch secured to frame 17 by bracket 53 in the position it would have when brush 22 is on: con.- tact 16. Armature L5 is attracted. by magnet 28, the catch 27 is released, and spring- 56 forces rod 39 to bethrown down, contacts 24 are opened, and pawl 25 is raisedby lever 26 which engages rod'39. Suppose now, the core- 20 to be for the first time on its downward motion and brush 22 reaches contact. 16, pin 40 which is at the top in the square tube 21, is down far enough to clear pawl 25. Now the current throughthe coils e and a is cut ofiby the opening of contacts 24. The length of movement increases with each stroke until the length of stroke desired has been reached. The length of stroke is determined by the number of coils in the solenoid B. The number of pins 40 in the square tube 21 is determined by the length of stroke. The side of tube 21 which faces pawl 25, is cut away above the pins 10 the full length of stroke so as to clear the pawl 25 after it has been caused to rise when brush 22 passed on contact 16. At each return motion of the bell -44- and tube 21 with its members carried thereby, one of the pins 40 engages pawl 25, closing contacts 24 which causes the coils to be energized as hereinbefore described.
The arrangement is-such that the move ment of the core 20 and the movement of the magnetic field which actuates the core 20 is simultaneous.
The speed of the reciprocating motion of the corewhenattached to a bell rope iscontrolled by the bell itself. That is, whether fast or slow, uniform or not uniform, or as in the case of a bell, approximately simple harmonic, the core 20 and consequently the moving magnetic fieldv follow properly the motion of that to which the motion is transmitted.
Changes may be made in the construction, arrangement, and dispostion of the various parts of the invention, within the limits of the appended claims, without in any way departing from. the field and scope of the invention, and it ismeant to include all such within this application wherein only one form of the invention has been disclosed in order to clearly illustrate the same.
