FRED LUX, OF WATERBURY, CONNECTICUT, A-SSIG-NOR OF ONE-HALF TO PAUL LU'X, OF WATERBURY, CONNECTICUT.

MOTOR.

Application filed December 29, 1913.

To all whom it may concern:

Be it known that I, FRED LUx, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Motors; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a front view of a motor constructed in accordance with my invention in its position of rest. Fig. 2 an end view. Fig. 3 a rear view. Fig. 4 a top or plan view. Fig. 5 a rear view with the weight in its raised position and the rack at the limit of its upward movement preparatory to moving downward, this figure showing the armature down ready to be raised by its spring. Fig. 6 a detached view of the driving gear and the stop ratchet in connection therewith, showing the position assumed after the weight has started in its downward movement. Fig. 7 a similar view of the gear with the ratchet removed. Fig. 8 a perspective view of the stop ratchet, detached.

This invention relates to an improvement in motors, and particularly to motors in which the power is derived from a weight which weight is in turn operated by intermittently applying electromagnetic power.

The object of this invention is to provide a motor adapted for operating mechanical display devices for show window's either by direct application or through a pendulum; and the invention consists in the construction hereinafter described and particularly recited in the claims.

In carrying out my invention, I employ a suitable frame herein shown as consisting of a front plate 2 and a rear plate 3 connected by posts 4. Mounted between the plates is a main shaft 5 on which is loosely mounted a pinion 7 and fixed to the pinion is a fly wheel 6. The pinion 7 meshes with a rack 8 loosely mounted on a shaft 9, and formed with an upwardly projecting arm 10 to which a weight 11 is secured. This rack is also provided with a rearw'ardly extending stud 12 insulated from the rack and adapted to be engaged by an arm 13 secured to a collet 35 which is rigidly mount- Specifieation of Letters Patent.

ed on the shaft 9, said collet also carrying an armature arm 14 connected with an ar- '1nature 15 directly over the poles of electromagnets 16 one terminal of the coils being connected with a binding post 17 forming part of the rearwardly projecting stud 12; and the other terminal connected with a binding post 18 which is insulated from the frame. The frame itself is provided with a bind1ng post 19. On the shaft 9 is a 0011 spring 20 the tendency of which is to lift the armature. Fixed to the shaft 5 is a ratchet wheel 21 adapted to be engaged by a pawl 22 pivotally connected with the fly wheel 6 and forced into engagement with the ratchet wheel by a spring 23. Loose upon the shaft 5 is a large gear wheel 24 provided near its hub with a segmental slot 25 to receive a pin 26 projecting inward from a ratchet wheel 27 which is rigid upon the shaft 5 and adapted to be engaged by a pawl 28 mounted on an arbor 29 and pressed by a spring 36 to engage with the ratchet wheel 27 to prevent reverse movement. Fixed to the large gear wheel 24 is a spring 30 which engages with the forward face of the pin 26 for the purpose as will hereinafter appear. The gear wheel 24 meshes with a pinion 31 fixed to a shaft 32 which carries a driving disk 33 through which power may be transmitted directly to the device to be pperated or adapted to operate the penduum. i

If desired, a driving disk 34 may be fixed directly to the driving shaft 5 as shown in Fig. 4:; and it is apparent that if desired the driving disk 33 may be omitted, and power derived from the disk 34. The advantage of this will be to derive greater power.

Starting from the position shown in Fig. 1, electrical current is applied through the binding posts 18 and 19 to energize the magnet 16, the circuit being closed through the engagement of the arm 13 with the stud 12 which will draw the armature 15 downward, and this downward movement of the armature suddenly raises the arm 13, so as to rapidly rotate the fly wheel 6., The fly wheel having had momentum imparted to it, will continue to rotate after the armature strikes the rack, and this continued movement of the fly wheel will go on to raise the weight until the power imparted to the fly wheel is exhausted, at which time the weight will be raised to the position shown in Fig. 5. This continued upward movement of the arm 8 carries the stud 12 out of engagement with the arm 13 and thus breaks the circuit, allowing the armature to assume its normal position, under the action of the spring 20. In the upward movement of the weight the rack rotates the pinion 7 and the fly wheel 6 connected with it during which movement the pawl 22 carried by the fly wheel rides freely over the ratchet 21, but engages the ratchet the moment the weight starts on its downward movement. As the weight begins to descend the pawl 22 engaging with the ratchet 21 turns that ratchet and thus the shaft 5 which in turn moves the ratchet 27, which by the engagement of the pin 26 with the slot 25 will, after the pin has moved through the length of the slot 25, move the gear wheel 24 and hence turn the disk 33. This movement of the pin 26 has placed tension on the spring 30 so that after the ratchet 27 has imparted movement to the gear 24: 1t Wlll allow that gear to have additional movement corresponding to the length of the slot 25 while the weight 2 is again being thrown up by the electromagnets owing to the fact that the stud 12 again comes into contact with the arm 13 to close the circuit. The slight movement imparted by the spring 30 is sufficient to keep the disk 33 moving while the weight is rising. It will thus be seen that the operation of the disk is practically continuous as it is moved forward on each downward movement of the weight, and is provided with suflicient movement by the spring 30 beyond that directly imparted to it by the weight to insure its continuous rotation during the time occupied by the weight in rising.

I claim 1. In a motor, the combination with a driving shaft, of a fly wheel loosely mounted thereon, a weighted rack adapted to turn said fly wheel, connections between the fly wheel and the driving shaft, and electrical means for intermittently imparting movements to the fly wheel to raise the said weighted rack.
