CONNECTING MEANS FOR DRIVING To all whom it may concern:

Be it known that I, AsA S. CREEK, a citizen of the United States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented certain new and useful Improvementsm Connecting Means for Driving. and. Driven Shafts of a Spring-Motor and Churn, of

which the following is a specification.

- My invention relates to means for detachably connecting driving and driven shafts, such as are embodied in a spring motor and churn driven thereby.

An important object of the invention is to provide means of the above mentioned character, which are simple in construction, inexpensive to manufacture, and convenient in ilse.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this-specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of apparatus embodying my taken on line 3-3 of Fig. 1, Fig. 4 is an enlarged detailelevation of a detachable coupling or clutch mechanism for connecting the driving element of'the spring-motor and the dasher or beater ofthe churn, Fig. 5 is a plan view of the entire'apparatus,

Fig. 6 is a transverse sectional view taken on line 6- 6 of Fig. 5, and, Fig. 7 is a longitudinal sectional view taken on line 7--7 of Fig. 5. V

In the drawings, whereinfor the purpose of illustration is shown a preferred emb0diment" of my invention, the numeral 10 designates a horizontally arranged-base or support, provided uponits upper surface with upstanding spaced flanges or ribs 11, extending longitudinally thereof, as more clearly illustrated in Fig. 5.

The numeral 12' designates a springmotor as a whole, arranged near one end of the; base .or support 10, as shown. This spring-motor comprises a pair of upstanding arms or standards 12, provided at their lower ends with downwardly diverging legs 13, terminating in feet 14, arrangedexte riorly of the ribs or flanges 11, and rigidly Specification of Letters Patent.

- movable handle or. crank 20, preferably provided at its outer end with a hand-grip 21.

The handle 20 is employed to rotate the shaft 17 in one direction to-wind up 'a main spring, to be described; Preferably formed integral with the clutch-member 18 is a ratchet wheel 22, adapted to be engaged -by -a pawl 23, pivoted as shown at 24. One end of this pawl is provided with a weight 25,

: which serves to hold the pawl in-engagement with the ratchet wheel'22., The function of this pawl and ratchet wheel is to prevent the shaft 17 from rotatingin a direction to un- Rotatably mounted upon the shaft 17. be tween the bearings 16 is, a drum 26,one' end of .whichis permanently closed, by .-a head 27, and the opposite end ofwhieh is normally closed by a removable head 28, secured thereto by any suitable means. Arranged ithin the' rotatable drum 26 is a coil spring-29', oflsuitable strength or stillness and length, the outer end of this coil springbeing connected with the periphery of the drum while its inner end is connected'Iw'iththe shaft 17 ,as shown. The drum 26 is' rovided withpinion or ear teeth 30,

p fi

preferably at the periphery 0 such gear teeth engaging a small gear or pinion 31, rotatably mounted upon a transverse drum 26 and, connected with the standards or arms 12. 1 Rigidly connected with the small-gear or pinion 31 for rotation therewith is a large gear or pinion 33,.which may be held against rotation by a pivoted pawl 33, movable into I and out of engagement therewith. The gear or pinion 33 engages (and drives a smallgear or pinion 34, as

shaft 32, which isarranged below the the head. 27

shown. The gear or pinion 34 is rigidly mounted upon a horizontal stub-shaft 35,

extending longitudinally of the'base or supbase or support 10 is a churn 4O comprising a holding receptacle, body portion or supporting structure 41, which is preferably vertically arranged and extends transversely of the base or support 10. This receptacle 41 is provided at its upper end with an inlet hopper or spout 41, normally closed by a removable cover or lid 42. Connected with the lower portion of the receptacle 41 is an outlet spigot 43, for the discharge of the milk or butter-milk. The receptacle 41 is provided at its opposite ends with depending feet or supports'42, slidably engaging the upper surface of the base or support 10 and provided with openings or grooves 43, to receive the ribs or flanges 11, as more clearly shown in Fig. 6. From. this construction it will be obvious that the receptacle or body portion 41 of the churn is adapted to be bodily moved longitudinally of the base or support 10 toward and away from the spring-motor with the feet 42 slidably engaging the upper surface of the base or support 10, and properly guided thereon by the ribs or flanges 11, operating within the slots or openings 43. The receptacle 41 is* provided upon one of its ends with an outwardly bulging cup-shaped bearing 44, for receiving one end of a rotatable driven or dasher-shaft or spindle 45, which is rotatably and removably mounted within a stuffing box 46, formed upon the opposite end of the receptacle.

The numeral 47 designates a rotatable dasher or beater, as a whole, preferably comprising blades 48, increasing in width outwardly and apertured, as shown at 49. These blades 48 are rigidly connected and preferably formed integral with a tubular hub 50, adapted to be removably mounted upon the shaft or spindle 45. The shaft 45 is provided with a longitudinally extending groove 5 passing through one end thereof,

and adapted to receive a bolt 52, carried by the tubular hub 50. It is thus seen that the tubular hub 50 is removably mounted upon the shaft 45 and is splined thereto to rotate therewith, the longitudinal movement of the tubular hub in one direction being prevented by one end thereof engaging one end of the receptacle 41 and in the opposite direction by the bolt 52 engaging the end wall of the groove 51.

The shaft or spindle 45 extends outwardly beyond the stufing box 46 and is adapted to serve as a co-acting clutch-element to be inserted within the tubular clutch-element 38, such end of the shaft being provided with a transverse pin or bolt 53, adapted to enter the longitudinal grooves 39, as more clearly shown in Fig. 4. When the end of the shaft or spindle 45 is inserted in the tubular clutch-element 38 with the transverse pin 53 passing into the longitudinal slots 39, it is obvious that the shafts 35 and 45 are looked for rotation together.

The bodily movement of the receptacle 41 longitudinally of the base or support 10 away from the spring-motor, may be positively limited by a pivoted preferably Y- shaped latch 54, (see Fig. 5), which is pivoted to one end of the base or support 10, as shown at 55. The free ends of the arms of this latch are adapted to rest upon the ribs or flanges 11. and to engage the outer legs 42 of the receptacle 41, when the shafts 45. and 35 have beenconnected or coupled as hereinabove described.

The operation of the apparatus is as fol lows :Assuming that the churn is arranged in its operative position u on the base or support 10, whereby the s afts 35 and 45 will be coupled or connected, the operator connects the clutch el'ement 19 with the clutch-element 18, whereby rotation of-the handle 20 will rotate the shaft 17 for winding up the spring. The spring is retained wound up until the pawl 33 is moved to release the gear wheel, when the drum 26 rotates for unwinding the spring, such rotation being imparted to the shaft 35 through the medium of the intermediate train of gears. The shaft 35 rotates the shaft 45,

-whereby the dasher or beater 47 is rotated, to churn the cream.

When it is desired to remove the churn 41 former may be thoroughly cleaned or scalded, the latch 54 is swung out of engagement with the outer legs 42, whereby the receptacle 41 may be moved. horizontally away from the-spring-motor until the shafts 35 and 45 have been disconnected. Subsefrom the base or support 10, whereby the I quently to this the "receptacle 41 may be that when the shafts 35 and 45 are connect'ed or coupled, as 'hereinabove described, and the latch 54 swung toits operative position in engagement with the outer legs 42, i

it is impossible to remove the receptacle 41 particularly well adapted to cooperate, yet I do not wish to restrict the invention solely to this use, as the same may be used in driving difl'erent machinery.

It is to be understood that the form of 4 my invention herewith shown and described is to be taken as a, preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the inventionor the scope of the subjoined claim.

Having described my invention, I claim:

In apparatus of the character described, a substantially fiat,-horizontal base provided upon its upper side with longitudinal, up standing guide ribs; a substantially vertical standard rigidly connected with one end portion of the base; a substantially horizon-- tal drive shaft j ournaled through the standard and rotatable therein and held against perceptible longitudinal and lateral move ments; a supporting structure arranged above the base and rovided with pairs of depending, spaced feet' having transverse notches open at their bottoms for detachably receiving the upstanding guide ribs; a substantially horizontal driven shaft journalcd through the supporting structure withone end'adapted to be brought into alinement with the corresponding end of the drive shaft; detachable "clutch mechanism rendered active by the movement of the driven shaft into proximity to the drive shaft to lock the same together for rotation and to prevent perceptible vertical swinging movement of the driven shaft prior to the longitudinal movement thereof away from the drive shaft; and a vertically swinging forked latch pivoted to the upper side of the base near the opposite end thereof and having its free ends adapted to slidably engage the adjacent pair of legs of the supporting structure upon the downward movement of the latch to eflect the longitudinal movement of the supporting structure toward the active position and to lock the same in such position.

In testimony whereof I aflix my signature in presence of two witnesses.
