Specification of Letters Patent.

Patented Dec. 23,1913.

To all whom it may concern:

Be it known that I, SAMUEL E." CARLIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usefullmprovements in Motors, of which the following is a. specification.

This invention relates to improvements in motors, and more particularly to the type which derives its power from some medium which has been placed under tension, such as gravity motors, spring motors, etc.

This invention is especially designed for use in calculating machines and the like for imparting rotation to a controlling or power shaft, and one of the objects of the invention. is to provide an improved motor of this character capable of being intermittently operated, thereby obviating the noise and vibration of a continuously operating motor.

A further object is to provide improved means for rc-winding' or storing power in the motor and improved means for automatically rendering the re-winding mechanism active when the power of the motor has A further object 1s to provide improved means for automatically rendering the rewinding-mechanism inactive when the motor is re-wound. v

A further object is to provide an improved device of this character which will be simple, durable and cheap in constructiol'i, and

' effective and etlicient in operation.

To the attainment. of these ends and the accomplishment of other new and useful objects, as will appear, the'invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed. and shown in the accompanying drawings illustrating an embodiment of the invention and in which- Figure 1 is a top plan view partly in section of an improved device of this character constructed in accordance with the principles of this invention. Fig. 2 is a detail sectional view partly broken away, on line 2-2 of Fig. 1. Fig. 3 is a sectional view on line 33 of Fig. 1. Fig. 4 is a sectional view on line -1 l of Fig. 1.

Referring more particularly to the drawing and in the present exemplification of this invention, the numeral 10 designates a suitable support to which are secured brackshaft. outside of the bearings.

rotation with the gear 18.

'ets 11, 12, which brackets are provided with suitable bearings for the various shafts. The numeral 13 designates the driving shaft for the mechanism, that is, the shaft by means of which the various parts of the calculating machine are set into operation and journaled in the brackets and parallel with the shaft 13 is a. second shaft. 1 1, which latter shaft is held against longitudinal dis placement with respect to its bearings in any desired or suitable manner, preferably by means of retaining collars 15 secured to the Secured to the shaft 14, preferably between the brackets 11, 12, and adjacent the bracket 12 by means of a key or feather connection 16 is a pinion Wheel 17 which is provided with a wide periphery. Secured to the pinion 17 and for longitudinal adjustment on the shaft 1 1.

therewith is a gear wheel .18 which pref crably of a diameter somewhat larger than the diameter of the pinion 17. A clutch member 19 is secured to the gear 18 and is preferably in the form of a sleeve having a clutch face which sleeve surrounds the shaft 14;. Loosely surrounding theshaft 14 is a second sleeve 20 which may be of any desired length and is provided with a clutch member 21 secured to one end thereof and this clutch .n'iembcr 21 cooperates with the clutch member 19 to lock the sleeve 20 for The other extremity 9.2 of the sleeve 20 proj cts through one face 23 of a hollow drum 2 1, within which drum is arranged a coil spring 25. One extremity 26 of the coil spring is secured to the sleeve 20,. as shown more clearly in Fig. 2, and the other extremity 27 of the spring is secured to the inner face of the drum to form a yielding connection between the drum and the sleeve 20.

Extending around the periphery of the drum a gear 98 which may be of any desired diameter.- Secured to the other face of the drum is an escapement wheel 29, shown more clearly. in Fig. 3, and coiiperab ing with this escapementwheel is a. stop and release dog 30l- This dog is pivoted as at 31 intermediate its ends 32, 33 to a fixed support 34 so as to alternately engage and disengage the peripheral teeth of the escape ment wheel 29. A gear 35 is secured to and for rotation with the escapement 29, the drum 24- andthe gear 28, all of which parts are mounted to revolve loosely about the shaft 14. A gear wheel 36 meshes with the gear and is mounted loosely upon the I shaft 13. This gear 36 may be held against longitudinal displacement on the shaft 13 in any desired or suitable manner, preferably by means of its hub 37 engaging the bearingi'n the bracket 11 on one side and a collar 38 secured to the shaft 13 on the other side of the gear. A pinion 39 is secured for rotation with the shaft 13. This pinion 39 meshes with the gear 28 and is provided with a wide face so as to permit the gear 28 to be adjusted longitudinally on the shaft 14 and at the same time remain in mesh with the pinion 39. A gear 40'is loosely mounted on the shaft '13 and meshes with the pinion 17 and is held against longitudinal displacement on the shaft by means of collars 41 secured to the shaft. A ratchet gear 42 is secured to the sleeve 20'and surrounds the sleeve. This ratchet 42 is preferably located intermediate the clutch element 21 and the drum 24 and a retaining dog 43 having a yielding extremity 44 is provided and is. supported in any desired or suitable manner, preferably by means of the shaft 13 which passes loosely therethrough and spaced collars 45 secured to the shaft on each side of the dog. The yielding extremity 44 of the dog cooperates with and engages the teeth of the ratchet 42 and serves to lock the sleeve 20 against rotation in one direction while permitting it to freely rotate in the opposite direction. -Motion 'is imparted to the shaft 14 by means of a shaft 46 of a motor preferably of the electric type through the medium of a gear 47 secured to the shaft 46 and which gear 47 meshes with the-gear 18.

The clutch members 19, 21 are adapted to be separated to unlock the sleeve 20 and the associated elements from rotation with the shaft 14 by separating the clutch elements and for this purpose there may be provided a'ycke 48 which engages the clutch element 19, connected to which is an operating lever 49 and this lever 49 is pivoted as at 50 to a suitable support 51, which support is preferably formed by an extension of the dog 43. \V hen the lever 49 rocked about its pivot 50, the gears 1 S and 17 will-be shifted longitudinally on the shaft 14 and each of these gears being provided with wide faces, the gears may be thus shifted forwardly and baekwardly to move the clutch member 19 toward and away from the clutch member 21 without being moved out of mesh with the respective gears 47, 40.

Any suitable means may be provided for automatically rocking the lever 49 and for this purpose the lever may be provided with an extension having an an'ti;friction roller 53 journaled thereto and which antifriction roller preferably stands in close clutch elements.

gear 40 is provided with a cam 54 which is adapted to engage the anti-friction roller 53 when the gear 40 assumes a predetermined position so as to shove or rock the lever 49 in one direction, that is, toward the left, as shown in F ig. 1, so as to separate the A cam 55 similar to the cam 54 is provided on the gear 36 and this cam 55 is adapted to engage an anti-friction roller 56 journaled to a suitable support 57, which support preferably projects from a link 58, which link is connected as at 59 to the extension 52 on the lever 49. A switch 60 is connected to the link 58 and this switch 60 cooperates with contact points 61, 62, to which the conductors 63, 64, leading to the motor are secured, so that when the lever 52 is moved, say, toward the left from the position shown in Fig. 1 to separate the clutch elements 19, 21, the switch 60 will also be shifted to break the circuit through the motor which operates the shaft 46. 'Wl1BH the lever 49 is shifted in the opposite direction to cause the clutch elements 19-, .21 to engage, the switch 60 will also be shifted in the opposite direction to close the circuit through the motor. 7

In operation and assuming the parts to be in the posit-ion shown in Fig. 1, which is the position they will assume when the power of the spring. motor has been spent and just at a time when the re-winding. mechanism starts to o erate,'motion will be imparted to the sha t 46 of the electric motor, which will in turn operate the pinion 47, the gears 17,18, clutch elements 19, 21, and sleeve 20, the sleeve turning in the direction indicated by the arrow in Fig. 4, that is, so that the peripheral teeth of the retaining ratchet will pass the dog 44. During this operation, the drum 24 will be held against rotation by means of the pinion 39 on the shaft 13 and the gear 28. As the sleeve 20 rotates, the spring 25 in the drum 24 will be wound up. The cam 54 on the gear 40 and the. anti-friction roller 53 on the extension 52 of the lever 49 are so arranged with respect to each .other and with respect to the. spring 25 that at the time when the spring is completely wound the cam 54 will engage.theanti-friction roller 53 to shift the lever 49 so as to disengage the clutch elements 19, 21 and shift the switch 60 to break the circuit through the electric motor. Just at the completion of this cycle of operation, the elastic member '25 or the stored energy in. the spring motor will have a tendency to spend its force but will be retained against operation by means of the stop and release dog 30 cooperating with the escapement wheel 29. \Vhen the dog 30 is rocked from the position shown in Fig. 3 so as to move the extremity 32 out of engagement with the notch of the escapement, the spring 25 will rotate the drum 24 in a direction opposed to the cscapement wheel 29 when the extremity.

32 of the dog 30 is moved out of engagement with a tooth. WVhen it is desired to impart another step of rotation to the shaft 13, the

extremity 33 of the escapement 30 must be moved out of engagement with the tooth of the escapement wheel 29 and the extremity 32 will be caused to move into a position'to be engaged by another tooth. This operation may be continued each time the dog 30 is shifted until the power in the spring motor has been spent. The cam on the gear 36 and the" ant-i-friction roller 56 on the projection 57 are so arranged wit-h relation to each other and with respect to the spring 25 that just at the time the power in the spring is spcnt,-the cam 55 will engage the anti-friction roller 56 to shift the lever 49 in the opposite direction and thereby move the clutch elements 19, 21 into operative engagement and at the same time shift the switch (30 to complete the circuit through the elec tric motor and thereby rotate the sleeve 20 to re-wind the spring in the manner already set forth.

The sleeve 20 is held against rotation under the influence of the spring 25 by means of the ratchet wheel 42 and extremity 44- of the dog 43.

Any suitable means may be provided for locking the lever l9 in each of its adjusted positions "and thereby insure the proper positioning thereof and that it will be maintained inlsuch positions and for this purpose the extension 52 of the lever may be provided with spaced notches into each of which the extremity 66 of a dog 67 is adapted to enter. The dog 67 is pivotally supported as at 68 to a suitable support 69 and is controlled by an elastic member 70,

the tension of which is sulticient tolock the these stems pass through suitable bearings 73, Tet in a support 7 5 and are provided with heads '76, 77, which are adaptedtobe engaged and depressed, alternately. Obviously the stems 71, 72, are so arranged that when one is depressed the other will be elevated.

With this improved construction it will be apparent that the motor which operates the shaft 1.3 may be thrown into operation at the will of the operator, either during the time that the spring is being wound, or when the winding mechanism is inactive, inasmuch as the spring and the winding mechanism both tend to operate the motor in the same direction.
