CHURN.

SPECIFICATION forming` part of Letters Patent No. 264,598, dated September 19, 12382.

(No model.)

To all whom it may concern .Beit known that I, BENJAMiN F. ALDRIDGE, of Hill Springs, in the county of Henry and State of Kentucky, have invented certain new and useful Improvements in Churns; and I do hereby declare the following to be a fullclear, and exact description of the invention, such as will enable others skilled in theV art to which itpertains to make and use the' same.

churns, and it consists in certainY details in construction and combination of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is aperspective view of my improved churn. Fig. 2 is a view ofthe flasher-rod, showingthe manner of securing theoperatingstraps thereto; and Fig. 3 is a view of the adjustable dasher. A represents a suitable base, to which. the uprightstandardBisremovablysecured. This standard B is provided atits lower endwith the round tenon al,which latterpasses through asuitable opening in the said base and is secured therein by the wedge b. This standard is strengthened and heldin position by the side braces, C, which latter are secured at one end to the sides of the base and at their opposite ends 'to the sides ofthe standard B. This stan dard is provided ucar the upper end thereof with the two horizontal parallel bars D D', the lower one, D, of which rests on the shoulders c, and is secured thereto by screws. These bars rest over the base A and are each prof vided on their outer ends with the half-bearings E, in which the dasherrod F rests and moves.- This dasher-rod F is provided near its upper end with the circular enlargement or drum G, which latter rests between the bars D and Dl and prevents the said dasher-rod from moving vertically, and is also adapted for the attachment of the operating-straps I. This enlarged portion or drum G is provided with the recesses d, situated in different hori-Y zontal planes, the opposite side walls of which incline in opposite direction, or incline in the direction the respective straps take after they leave the recesses.

A projectinglug,f, is secured in the inclined side wall of each recess, but does not project up above the true circumference of the drum so .as to interfere with and wear away the oper-l ating-straps which are secured thereto. These operating-strapsI (two in number) are secured respectively to the operating-levers, while the opposite end s thereof pass around the drum in opposite directions, and are secured thereto by the lugsf. The outer or free ends of these straps are iirstrintroduced into their respective recesses, which completely protects the said ends, while they are secured to the said dasher- My invention relates to an improvement in rod by the lug'sf, 'which latter pass up through openings near the end ofthe straps. This construction serves to protect the end of the straps V'but would also give an irregular or jerking motion to .the dasher, which is not desirable. These straps pass around the drum on the dasher-rod in opposite direction, and are secured to the peripheries of the semicircular disks K by the screws g. These semicircular disks K are situated indifferent horizontal planes, the upper being ina plane with the top-strap attachment on the dasher-rod, while the lower one'is in a plane with the lower-strap attachment on the dasher-rod. These dasher-rod attachments and semicircular disks are separated suiciently so as to prevent the straps-from rubbing or interfering with each other duringv the operation of the machine.

L and L are horizontal operating-levers, pivotally secured to the standards B and connected together by the loose handles M. The

lower lever, L, rests on the bar D, while the upper lever, L', is situated above the bar D and rests on a shoulder (notshown) formed near the upper end ot' the standard B. The upper end of the standard B passes centrally through the two levers L and'L, and the two semicircular disks K are secured to the said lower lever, L, on opposite sides ot' the said standard. The lower semicirculnr disk is secured directly to thelever L, while the upper semicircular disk K is rigidly` secured to a bearing-block, h, which latter is secured di. rectly to the lever L. As the two levers L L are connected together by the vertical handles- M, it follows that as the handles are moved in the arc of a circle around the standard B `both levers L L are also caused to move simultaneously therewith in the'same direction. This construction forms a solid and substantial frame and prevents the handles M from being IOO bent or broken off, while the connections be tween the said levers and standard are such that there is little or no friction produced while operating the machine.

The straps I are so connected to the drum that when one is wound thereon the other is unwound, and as the vibrating` motion is coutinned the straps are successively wound and nnwound on the drum.

A fan, N, is secured to the top lever, L', to fan the operator while the churn is in operation, and a. second fan or brush, N', is secured* to the dasher-rod, just above the head of the churn, to prevent dust or dirt from falling into the said head, and also to keep oti' insects and i'lies. The lower part of the dasher-rod is t'ormed square, which not only assists in converting the cream into butter, but aftords increased bearings for the extensible dashers, which are secured thereto. f

The dasher-rod F is provided with two openings, i, through the same, through which the horizontal barsj ofthe flasher() pass. These bars j are provided with the horizontal beaters r, secured on opposite sides otthe said bars, as shown, so as to present as much beatingsurtaee as possible. The inner ends ofthe barsj are adapted to pass through the openings i from opposite sides ot' the dasher-rod, and rest one above the other, and are secured in the position by the screws l, which pass through one side of the dasher-rod and between the two bars t', and act as a wedge which holds them securely7 iu position. By simply removing the screws l the dasher can be increased or decreased in width, soas to suit the churn P, which can be of any size and construction.

'lhe horizontal bars eau be elevated, so as to accommodate churns of ditferent sizes, and the standard B can be secured to any suitable base in anysuitable manner. The construction previously described, however, answers all the necessary purposes.

My improvement is simple in construction, is strong and durable in use, and can be manufactured at a small initial cost.

It is evident that slight changes in the construction and relative arrangement of parts might be resorted to withoutdeparting from the spirit of my invention; and hence I would have it understood that I do not limit myself to the exact construction of parts shown and described, but consider myself' at liberty to make such changes and alterations as come within the spirit and scope of my invention.

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

l. In a vibrating churn, the combination, with a standard having two operating-levers pivoted thereto, handles connecting the said levers at opposite ends, and two semicireular disks rigidly lsecured t0 one ot said levers on opposite sides ot' the standard in different horizontal planes, ot' a dasher-rod provided with a drum, and operating-straps placed in dilierent horizontal planes and adapted to connect the said semicircular disks with the said drum, substantially as described.

2. The combination, with the dasher-rod provided with two openings, of a two-part dasher, the horizontal bars of which are adapted to pass through said openings and rest one above the other therein, and screws adapted to pass between said horizontal bars and hold them together. substantially as described.

In testimony whereof I have signed this specification in thepresence of two subscribing,r witnesses.

BENJAMIN FRANKLIN ALDRIDGE.
