IMPROV-ED MECHANICAL MOVEMENT.

TO ALL WIIOM IT MAY CONCERN: Be it known that I, MORHI'S F. SPORS, of Preble,in thecounty or". Cortland, and State of New York, have invented a new and useful Improvement in Mechanical Movements for operating churns, pumps, and other i similar machines; and`I do hereby declare that thesfollowing is a full, clear, and exact description of the same,

reference being had tothe accompanying drawings forming part of this specification, in which-.-

Figure 1 is a perspective view of my improved mechanical movement,- viewed from the right-hand side thereof.

lFigure 2 is a similar vien', looking at the left side of the machine.

Figure 3 is a partialvieri of the right-handside of the maehincyillustrating the manner of adjusting the escapement-pallets and pendulumvby red lines.

Figure 4 is a similar view of the lefthand side of the machine, illustrating the manner of adjusting the pinion and spur-wheel shaft, which transmits power to the crank-shaft, also by red lines.` i

Similar 'letters 'of'referr'ce irrt-heseveral figures indicate corresponding parte.

The invention which I have made is designed to render more useful for general purposes the-clock-movement or power heretofore adopted for driving various kinds of machinery, and more particularly for operating churns.

The nature of my invention consists, first, in a nevel arrangement ofthe eseapcment-pallets and the pendulum upon an adjustable arm or `lever, whereby the pallets and pendulum can be readily adjusted, so as to not offer resistance tothe escapemeut-wheel during the winding up of the weight which is to propel the movement;second, and in connection with the foregoing, it further consists in a novel arrangement of the pinion mand spurwhecl shaft, from which thc power of the clock-movement is transmitted to the crank-shaft of a churn,

lsaw-mill, or pump; said arrangement being such that the friction and resistance heretoforeV produced by said wheels upon the clock-movement, while winding up the weight thereof, maybe removed, and thus the labor and time expended in winding up the weight greatly reduced. i

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.l I

A represents a strong frame, madeeither of wood or iron, and adapted for supportingjhe gearing which I 'e'mploy,rand also a reciprocating pitman and slide. At the lower part of this frame, betweenl the two uprights thereof, a` anged drum, B, is arranged upon a shaft, `C, and at the top of said frame two pulleys, D and E, are

' 4 arranged as shown.M Around the drum and over the pulleys, the cord or chain which carries the weight is' wound` and passed, as'shown. Between therdrum and the shaft of the pulley D a. system of gearing, F G I-I I J K L, is arranged upon shafts IVI N O P, asrcpresented. The wheel F of this train of gearing gears with a' toothed wheel, Q, on the drum-shaft C, and by this means the whole .train is set in motion, when the weight is allowed to pull upon the cord or chain R of the drum. The shaft N has an escapement-w-heel applied on it outside of the right-hand upright ofvthe'frame A,` and to the extremity of` this sha-ft a hand-crank for winding up the weight is applied, as represented. t

The escapement S, with the pendulum T, is arranged on a lever or pivoted arm T1, which has oneA of its ends pivoted tothe righthand upright of theframe A. Its other end is left free, and is furnished with a handle, by which the arm with the escapement and pendulum can be adjusted so as not to gearlwith the escape# wheel. For the purpose of retainingthelevcr in a position which -will either keep the escapgement out of gear .or in gear, a stop-plate, U, is applied on'thc back edge of the right-hand upright of the frame.. This plate has a projeeting'tootln'a, upon which the lever rests when the escapementis in gear with the escape-wheel, said tooth being bevelled so that the lever, when a slight outward movement is imparted to it, may be moved down- Ward without obstruction. In-order to obtainthis slight outward movement, the lever must be pivoted quiteloose, or have a slight spring action in itself. The object in thus arranging the escapement is to afford facility for throwing it outfof gear when it is desired to wind up the' Weight.

The shaft has its journals fitted loosely in the uprights of the frame, one journal lbeing passed through an oblong vci'tical slot, CZ, of. the left-hand upright of the frame A, and supported upon a handlever, T2, which, is pivoted to said upright by one vof its ends, a'nd left free at its other end. In order to retain this lever in any position desired, a stop-plataf, is applied on the rear edge of the said upright. This stop-plate has a rectangular projection, g, formed o n it, upon and under which the lever bears accordingly as the lever is adjusted, To get this lever by the stop'its pivot must be fitted loosely through it, or the lever must have a spring action in itself. By raising the lever T2, that end of it which passes through the slot d can be raised or lowered, as desired.

The great advantage or object of arranging the shaft O so that one of its ends may bc raised, and lowered after having been raised, is that the gear-wheel J may he thrown in and out of gear with the clock-movcment out of gear when the weight is to be wound up, and in gear after it is wound up.

On the left-hand end of the shaft P a crank-wheel, W, is applied, the wrist-pin of said crank-wheel being adjustable, so as to lengthen or shorten the throw of the crank-movement. To the wrist-pin a pitinan, X, is attached. This pitman is connected to a slide, Y, which Works in guides on the side of the frame, as rcpresented. The slide Y has a connecting-device, Z, which serves to connect the staff of a churn-dasher, piston-rod of a pump, or any other similar machine.

From the foregoing description itis apparent that the action of the weight upon the train of gearing will give a rapid reciprocating motion to the pitman-slide, and while the motion is rapid the unw-inding of thc weightcord will be very slow and gradual. The speed of the drum upon which the cord is wound may, however, be quicliened by raising the ball of the pendulum, provision, as nsual, being made by a setscrew, (Z, for suoli adjustment.

My invention will greatly enhance the value of clock-movements as a power for operating machinery; and as such powers can be used for churning, and other purposes, the same operating a c hurn or pump for twelve or twenty-four hours, automatically, they are very desirablepowers for farmers and others.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The arrangement of the escapement-pallets upon apivoted arm or lever, and employing the samcthus arranged in combination with a clock-mechanism, asn means for operating a pump, churn, or other similar machine, substantially as herein described.

2. The arrangement of the shaft which carries the pinionvan'd spur-wheels which transmit the power. of' the clock-movement to the crank-shaft, upon the frame A, and upon a hand-lever, in suche manner that said wheels can be thrown out of and in gear with the clock-movement, substantially as described.

3. The arrangement of the train of gearing Aherein described, hand-adjusting lovers, pendulum, weight,

' and reciprocating slide, all substantially as and for the purpose set forth.
