CHURN.

SPECIFICATION forming part of Letters Patent No. 615,676, dated December 13, 1898.

Application filed October 9 A1897.

T0 @ZZ whom, t may concern:

Be it known that I, WILLIAM TAZnwILL BURROUGHS, a citizen of the United States, residing at Bluefield, in the county of Mercer and State of Vest Virginia, have invented a new and useful Ohurn, of which the following is a specification. l

My invention relates to churns and the objects and advantages of the same 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 side view of a churn mechanism constructed in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a transverse vertical section of the operating mechanism on the line 3 3 of Fig. 2. Fig. 4 is a perspective view of the receptacle-holding and dasherstem-guiding devices. Fig. 5 is a detail hori- Zontal section to show the guiding devices for the dasher-stems and the means whereby the churn-receptacle lid is removable without disconnecting the dasher-stems. Fig. 6 is a detail sectional view to show the manner of mounting the lid upon the receptacle. Fig. 7 is a detail section to show the swiveled bearing for the intermediate or counter shaft.

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

Rising from a base 1 are standards 2, connected by suitable horizontal braces 3 to form asupporting-frame,and mountedtransversely in suitable bearings supported by said frame is a driving or drum shaft L1, provided with independent drums 5 and 6, upon which are reeled weight-cords or connections 7. These weight cords extend over elevated guides consisting of pulleys 8, supported by derricks or uprights 9, rising from the supportingframe, and the weights 10 are provided at their lower ends with hooks 11 and at their upper ends with eyes 12 to provide for employing a series of weights for suspension by each cord. This enables the operator to vary the weights to suit the work to lbe accomplished. The drum or driving shaft may be provided .with any suitable means whereby it may be rotated to wind the weight-cords; but

Serial No. 654,699. (No model.)

I prefer to fit it at one end with a key-seat 13, adapted to receive a crank, (not shown,) and it is also desirable to t said shaft with a ratchet mechanism 14, whereby it may be held from backward rotation during the wind ing of said weight-cords, this ratchet mechanism to be thrown out of gear by disengaging the pawI thereof from the ratchet-wheel when it is desired to operate the mechanism.

Thepdriving-shaft carries a driving-gear 1I, by which through intermediate gearing motion is communicated to a crank or driven shaft 15, also mounted in suitable bearings upon the frame and provided with terminal crank-arms 1G, connected by pitmen 17 with dasher-stems 1S. The body portion of the crank-shaft is cross-sectionally squared or otherwise constructed to provide for the removal and replacement of a pinion 19 and a balance-wheel 2O without allowing relative independent rotation of said parts, and the terminal cranks of said shaft are reduced toward their free ends to provide for taking said pinion and balance-Wheel on and off over the crankarms, which are preferably ,constructed integral with the shaft. The pitmen are connected with the crank-arms by means of suitable wrist-pins 21 on the latter and are bifurcated at their lower ends to receive the contiguous extremities of the dasherstems, split keys 22 being engaged with registering openings in the pitmen and dasherstems to provide for the disconnection of said parts with facility.

' The preferred construction of means for communicating motion from the driving-gear on the driving-shaft to the pinion on the driven shaft includes an intermediate or counter shaft 23, provided with a pinion 24 for meshing with said driving-gear and a gear 25 of -larger diameter for meshing with the pinion on the driven shaft. This intermediate or counter shaft is mounted in bearings on the frame, one of those bearings, 26, being swiveled, while the other, 27, is movable toward and from the driving-shaft to provide for throwing the pinion 24 into and out of operative relation with :the driving-gear 4a. Said movable bearing 27 is carried byaslide 2S, mounted in a suitable guide 29 on the IOO su pporting-frame and connected with a shiftlever 30, which is fulcrumed at 31 upon the supporting-frame. In this connection I also employ a brake-bar 32, mounted in a suitable guide 33 and provided with a toothed extremity to engage the teeth of the drivinggear 4L and lock the mechanism against rotation when it is desired to check the operation of the machine with the actuating-weights in an elevated or operative position. Said brake-bar is connected with an operating-lever 34, fulcrumed upon the framework.

The churn-receptacle 35 is fitted in a seat on the base l, said seat consisting of a plurality of iixed blocks 36 and a movable block 37, pivoted, as at 3S, to the base and provided at its free end with a locking device consisting of a hook 39 or its equivalent for engaging an eye 40. It is obvious that when this movable seat-block is locked in place the churn-receptacle is held at its bottom against movement, and in order to remove the receptacle it is necessary to displace said movable block, as indicated by dotted lines in Fig. 4. The churn-receptacle is provided with a removable lid or cover 4l, provided on its under surface with strips 42 to fit within the top of the .receptacle and also provided with guide-openin gs 43, through which the dasherstems 1S extend. In order to allow the receptacle lid or cover to be removed from the receptacle without disconnecting the dasherstems from the pitmen, I provide said lid or cover with movable sections 44, pivotally mounted at one end by hinge-straps 45 or their equivalents upon the main section of the lid or cover and extending inwardly to the guide-openings 43, whereby when said movable sections are swung laterally to oocupy a position indicated in dotted lines in Fig. 5 said guide-openings are opened to one edge of the lid. lVhen the churn is in operation, it is necessary to hold the lid of the receptacle firmly in place, and to accomplish this I employ holding bars 46, pivotally mounted, as at 47, upon the frame and rovided in their under sides with rabbets 4S, which engage the edges of the lid or cover. The free ends of these holding-bars are held in their depressed or operative positions by means of a bail-lock 49, having its arms pivotally mounted upon the standards of the frame and adapted to swing over said free ends of the holding-bars when the latter are engaged with the churn lid or cover. This lock is provided with an operating knob or handle to facilitate its disengagement from the holding-bars. In connection with the holding bars I also preferably employ a dasher-stem guide 5l, arranged transversely of the frame and terminally supported by brackets 52 on said holding-bars, and this guide-bar is provided with dasher-steni guideopenings 53, closed by swinging blocks 54, hinged or otherwise movably mounted at 55 upon the body of the bar and adapted to be secured in position at their free ends bya common locking device consisting of a button 5G, which is pivotally mounted upon the body portion of the bar. lVhen it is desired to raise the holding-bars to release the churnreceptacle without disengaging the dasherstems from the pitmen, this locking device 56 should be turned to disengage it from the closing-blocks 54, after which the holdingbars, previously released by the bail 49, may be elevated to disengage the rabbets 48 from the churn lid or cover. It will also be seen that the dasher-stems may be disengaged from the pitmen to provide for the removal of the dashers, with the churn-receptacle, from the supporting-frame, the closing-blocks 54 first being released and the bail-lock 49 being elevated to disengage the holding-bars.

In practice I prefer to employ a churn of medium depth and provide perforated plungers 57 ,which while having onlya small throw are adapted to thoroughly agitate the contents of the receptacle, and thus hasten the operation of churning.

Various changes in the form, proportion, and the minor details of construction maybe resorted to without departing from the spirit or sacriiicin g any of the advantages of this invention.

Having described my invention, what I claim is- 1. The combination with a supportingframe, and a churn-receptacle seated upon the base of the frame, of a receptacle lid or cover having guide-open ings for dasher-stems and provided with swinging sections movable in the plane of the lid or cover,whereby said guide-openings are normally closed, pivotal holding-bars mounted upon the supportingframe for vertical swinging movement and provided with rabbets for engaging opposite side edges of said receptacle lid or cover in the paths of the swinging sections thereof, and means for securing said holding-bars in their normal positions, substantially as specified.

2. The combination with a supportingframe, and a churn-receptacle seated upon the baseframe, of holdingbars pivotally mounted upon the frame for vertical swinging movement, a guide-bar supported by said holding-bars at intermediate points and provided with dasher-stem guide-openings iitted with closing-blocks, means for securing the closing-blocks in their normal positions, a receptacle lid or cover removably fitted upon the receptacle in the paths of said holdingh bars for engagement thereby, and means for securing the holding-bars in their normal p0 sitions in engagement with opposite edges of the lid or cover, substantially as specified.

3. The combination with a supportingframe, and a receptacle seated upon the base of said frame,of holding-bars pivotally motilited upon the frame for vertical swinging movement, and adapted to bear upon the receptacle lid or cover, a guide-bar carried by the holding-bars at intermediate points and provided with flasher-stem guide-openings fitted IOO IIC.

with movable closing-blocks pivoted to the bar at their remote ends, a common lockingbutton 5G for engaging the adjacent ends of and securing said closing-blocks in their normal positions, and means for securing the holding-bars in their normal positions in engagement with the receptacle lid or cover, substantially as speciied.

4. The combination with a supportingfrarne, flasher-operating mechanism including a driving-shaft and pitmen actuated thereby, and a churn-receptacle seated upon the base of the supporting-frame, of a receptacle lid or cover removably fitted upon the receptacle and provided With dasher-stem guideopenings and pivotal closing-blocks for said openings, said closing-blocks being mounted to swing laterally in the plane of the lid or cover, dasher-stems extending through said guide openings and detachably connected with the pitmen, pivotal holding-bars mounted upon the supporting -frame for vertical swinging movement and rabbeted to engage the side edges of said receptacle lid or cover and closing-blocks, a guide-bar carried by and spanning the interval between the holding bars and provided with dasherstem guideopenings and movable closing-blocks for said openings, means for securing said guide-bar closing-blocks in their operative positions, and a swinging bail mounted upon the supporting-frame to normally occupy a position vin the paths of the free ends of theholdingbars to prevent swinging movement thereof, substantially as specified. v

In testimony that I claim the foregoingvas my own I have hereto affixed my signature in the presence of two witnesses.
