TO ALL WHOM IT MAY CONCERN:

Be it known that I, -CHARLES H. ELLIOTT, of'Yorldin the county of York, andState of Pennsylvania, have invented anew and improved Churn; and I do -hereby declare that the followingis a full, clear, and exact.

description thereof', reference being had to the accompanying drawings, making a part ofv this specification,

in which- Figure 1 is a perspective view ofthe improved machine complete.

Figur-0.2 is a longitudinal section taken i-n a vertical plane through the centre of the machine.

Figure 3 is a transverse section taken through the centre ofthe machine.

Figure 4 is a sideview o the dashe'r, detached from the machine.

Similar letters -of reference indcatec'orresponding parts in the sevcraltigures.

This invention relates to certain new and useful improvements on that class. of power-churns wherein the dasher receives a rotary motion about its airistand, at the same time, a vertical reciprocating motion.

The nature-of the first part oi'my invention consists in communicating a vertical or rectilinear reciprocating motion 'to a churn-dasher, at thc same time giving to this dasher intermittent right and left rotary motions about its axis, by ineuns'of a verticallyreciprecating dash, which is guided in a stationary frame, and a spirallygrooved dasher-shat, into the groovesofzwhich, teeth engage, which are applied to a stationary cross-head, as

will be hereinafter explained. v

The second part of my'invention consists in applying" to the .dash-roda suitable perforated disk, and a number of radial arms, carrying fixed and rotating lWings, which win-gs are designed to serve in conjunction vvith the disk to break up the lmtter-globnles to the best advantage, and with the greatest possible facility, as

will be hereinafterl explained. 5

The invention further consists in providing a churning-machine, of the construction hereinafter set forth, with means whereby the vessel for containing the cream can be readily removed from and ,applied to the frame and working parts ofthe machine said means consisting of a removable cross-head, arranged over the said vessel, and a depression on the hed ofthe machine, for receiving and centring this vessel and keeping it steadily I in place,ias will be hereinafter explained. v

To enable, others skilled i`n the art to understand my invention, I will describe its construction and operation. In the accompanying drawings, A represents the horizontal bed of the machine, which may be constructed as shown in the drawings, or in any other suitable manner which will afford a substantial foundation for supporting the churn-vessel, andthe several parts' used for moving the dasher. Upon this bed are uprights, B B,

which are connected together hyhorizontal pieces, B', at their upper ends, so as to form a strong rectangular frame,l for receiving and serving as a guide for a vertically-reciprocating sash, C. `\Tl1is sash moves up and down between, and is kept in place laterally by means'of upright strips, a aand D D, `which are applied to the frame-nprights B'B, substantially as shown in fig. 1, so as to form recesses, in which the vertical legs of the` sash C slide. The lower lextremitiesof the sash are connected, by means of rods b b, with-tho wrist-pins ot crank-arms c c, which arms are keyedl upon 'the extremities of a shaft, E. This shaft E is located beneath the top ofthe bed A, and is supported in bearings c c. It carries upon it, near one end, a grooved pulley, F, over which a belt, d, passes, Ywhich also passes over alarge cirenmferentially-grooved driving-wheel, G. This drivingwheel is applied upon a short shaft which has itsA bearings 'upon the upper end 'of an inclined post, H, and by means of crank handle, I, shown in iig. 1, said wheel G can be convenentlv rotated, and motion imparted tothe shaft E and sash C'.

Instead of the wheels F` Gr, any other suitable means may be adopted-for giving motion to the crank-shaft, and, if desirable, provision may be madetor driving the churn-movement by animal or other convenient motivepower.

On top ofthe upright inside pieces D, and secured to these pieces by hooks, S, or other convenient fastening, is a. horizontal head-piece, D', the extremities of whichare notched, so as to embrace the upright strips aa, thereby preventing it from slipping out of place laterally. Through the middle of the length of thishad-piece D' 1s a notch, V, through which a spirally-grooved portion, f, of the dash-shaft N plays. On top of this hea'd piece, and screwed thereto by thumb-screws, J' Jl, are two adjustablel plates, J, carrying on their ends,nearcst the grooved portionf, oblique teeth, e e, which enter the spiral grooves f on opposite-sides ofthe portionf, and thereby cause the dash-shaft to rotate in one direction when it is elevated, and an opposite direction when thisshaft is depressed. The thumb-screws pass through oblong slots made through the extremities of the plates J J, so that by loosening' thesel thumb-screws, the plates can be moved back, and the teeth e e retractedfrom their spiral grooves.

The upper end of the dash-shaft terminates in a reduced cylindrical portion, t', having 4an annular groove made in it, which portion enters a hole made through the centre of the horizontal cross-head of the sash C, and receives through its groove a transverse key, t. VThis key attaches the upper end of the dash-shaft to the sash, and allows the dash-shaft to rotate freely about its axis. p V

The dash-shaft N passes down vertically through the centreof a circular cover, K, which is itted'nponia cylindrical churn-vessel,- K, shown in figs. 1, 2, and 3, and upon the lower end of this shaft is-a circular perforated disk or dasher, P, which serves, in conjunction withl several radial wings uponrthe dash-rod, to produce butter very rapidly.

The vessel K' is fitted into an annular recess, formed by the ring-base L, which latter is secured down''ast4 upon the base, A, as shown in the drawings. The base-ring is suihciently high to form a receptacle, which will centre and keep in place the vessel K', and allow thisrvessel to be removedfrom the machine at pleasure, when the head-piece D' and key t are detached. I

The radial wings, gg and l. L, are perforated and secured to short arms, which radiate from the dash-shaft N, as shown clearly in figs. l and 4. The radial wings j are secured to tubes, and applied upon arms z'z', which radiate fromthe dash-shaft, so that the wings j are allowed to rotate by the resistance of thevcream impinging` Vupon them. These wings, together with the perforated dasher P, will cause violent agitation of the mill: er cream inthe vessel K when the sash Cis reciprocated, and produce the butter in a very short space of time. Y It will be seen that the wings are brought into action by the vertical as well as the rotary motion of the dash-shaft, while the dasher P operates only by the vertical motion Vof said shaft. When Ashaft E is4 rotfated, the sash C and dash-rod N receive avertical rcciprocating'motion. At the same time, the teeth e e, engaging with the spiral grooves, f', upon the enlargem'ent,f, of the dash-rod, cause this rod to receive right and left rotary motions about its axis. l

The rectangular sash C, working in guides, formed as shown and described, will give a steady motion' to the dash-rod, and keep it in place during its up-and-down movements. i v

The teeth e e serve not only to give rotary motionto the dash-rod,`but they also serve to steady and rcentre it in its vertical movements.

The head-piece D' serves as a support for the plates J, and also as a brace to the frame of the machine. This piece is detached from its uprights D D, and raised a short distance, when it is desired to remove `the vessel K from its seat in the base-ring L. 1

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

i 1. Communicating a vertical reciprocating motion to the dash-rod N, at the same time giving to this rod right and left rotary motions, by means of a vertically-moving sash, C, a spirally-grooved portion,f, and fixed but adjustable teeth c e, arranged andapplied Within a frame, and driven from a shaft, E, substantially as described.

2. The movable head-piece D', arranged over the churn-vessel, and provided with .adjustable toothed plates J J', in combination withrsash G and a spirally-grooved portion,f, on the dash-rod, substantially as described. 3. The churn-vessel K', seated into a fixed base-ring, L, in combination with the movable head-piece D', and the means, substantially as described, for operating the dash-rod. l

4. The perforated dasher P, and dash-rod N, provided with perforated r imperforated radial wings, g'or h, constructed and applied substantially as described.

5. The rotary wings j, applied to rods z', projecting radially from the dash-rod, substantially as described.
