MOTOR.

SPECIFICATION forming part of Letters Patent No. 616,090, dated December 20, 1898.

Application filed February 21, 1898. Serial No. 671,145. (No model.)

T0 @ZZ whom it may con/cern:

Be it known that I, THOMAS DoUGLAss, a citizen of the United States, residing at Sarversville, in the county of Butlerand State of Pennsylvania, have invented a new and useful Mechanical Movement, of which the following is a specification.

My invention relates to mechanical movements, and particularly to motors whereby reciprocatory motion may be imparted to a churn-dasher or equivalent device; and the object in view is to provide asimple, compact, and efficient construction of combined escape-V ment and controlling or governing mechanism whereby the energy of a continuously-operating power, such as that supplied by a weight or spring, may be controlled and converted into a reciprocatory motion.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a motor constructed in accordance with my invention. Figs.'2, 3, and 4 are diagrammatic views of the parts of the mechanical movement in different relative positions. Fig. 5 is a view showing the application of a spring as a driving power.

Similar numerals of reference indicate corresponding parts in all the gures of the drawings. f

1 designates a revoluble power-shaft adapted to be actuated by a continuously-exerted powersuch as that supplied by a weight, spring, or the equivalent thereof-and carried thereby is a clutch-disk 2, provided with radial peripheral stop-pins 3, for engagement with a movable stop 4, arranged in the plane of the stop-pins and carried by a rock-shaft 5. Connected with the rock-shaft is a trip-arm 6,terminally disposed in the path of a trip-pendulum 7,'consisting of a shank 8, a bob 9, adj ustable by means of the shank 8, through the bolts 10, adapted4 to engage registering perforations 11 in the shank-sections 8a 8", and the latter being fulcrumed by means of a knife-edge bearing 12 or itsequivalent upon a standard 13, said pendulum-shank having bearing-eyes 14 or their equivalents to bear upon the knife-edge. The standard 13 is also to be reciprocated. This rock-shaft carries an oscillatory arm 19, provided with tappets 2O and 2l, arranged in the paths of tappetarms 22 on the clutch-disk 2 or otherwise mounted for rotary movement with the driving-shaft 1, and mounted for swinging movement parallel with said oscillatory arm and having an intermediate fulcrum 23 is a return-lever 24, having one arm connected with the oscillatory arm for swinging movement therewith and having its other arm disposed to engage an oifset 25 of the trip-arm. The connection between the lower arm of the return-lever and the oscillatory arm 19 consists in the construction illustrated of a slot 26 in the former engaging a pin 27 on the latter. Furthermore, the trip-arm is provided with an adjustable counterbalancing-weight 28, arranged upon au offset 29, which is located inthe plane of swinging movement of the trip and adapted to be secured at the desired adjustment by means of a set-screwSO. The function Aof this counterbalancing-weight is to vary the resistance offered bythe trip-arm to actuation by the pendulum and cause the trip-arm to maintain its normal position (with the stop 4 in the path of the stop-pins 3) until positively actuated by the pendulum and moved to the opposite limit of its path.

With the parts in the position illustrated in Fig. 2, the pendulum having been swung to the limit of its movement from the trip-arm, the return movement of the pendulum will bring its bob in contact with thetrip-arm, and by swinging the latter with it in the direction indicated by the contiguous arrow in Fig. 2 the stop 4 will be depressed out of the path of the engaged stop-pin 3, as shown in IOO Fig. 3, and will thus release the clutch-disk and the operating-shaft for movement in the direction indicated by the arrow. As the disk turns one of the tappeti-arms will engage the contiguous tappet 20, and thus-throw the oscillatory arm 19 to the limit of its movement in one direction, (thus elevating the free end of the arm 1S, as shown in Fig. 4,) and subsequently the preceding tappet-arm will engage the tappet 21 and swing the arm 19 in the opposite direction, thus depressing the free end of the arm 18. This return movement of the oscillatory arm 19 causes a corresponding movement of the connected arm of the return-lever 24, and thus, through the upper arm of the return-lever, causes the return movement of the trip-arm to the initial position indicated in Fig. 2.

In Fig. 1 I have shown the apparatus constructed for operation by means of a weight 31, of which the cord 32, afterpassing over a suitable guide-roll 33, is reeled upon a drum 3l on a winding-shaft 35, having a key-seat 3G and a ratchet mechanism of suitable construction whereby the weight-cord may be wound upon the drum without affecting the connection between the arbor 35 and the operatin g or driving shaft 1,said connection consisting of a gear 39 on the arbor meshing with a pinion 40 on the shaft 1. In Fig. 5, however, I have shown the apparatus constructed for operation by a spring 4l which is attached to an arbor 35,having connections constructed substantially as above indicated for communicating motion to the shaft 1. In said Fig. 5 I have illustrated a ratchet mechanism, consisting of a ratchet-gear 37 and a pave/138, suitable for allowing the rotation of the shaft 35 to wind the spring without affecting the gear 39, and it is obvious that a similar or any equivalent ratchet mechanism may be used in connection with the apparatus when a weight-cord is employed Various changes in the form, proportion, and the minor details of construction may be resorted toy without departing from the spirit or sacrificing any of the advantages of this in- Y vention.
