AARON C. VAUGHAN, OF JOHNSTOIVN, PENNSYLVANIA.

CHURN-IDASI-IER.

Specification of Letters Patent No. 27,396, dated March 6, 1860.

. To all whom it may concern:

Be it known that I, AARON C. VAUGHAN, of Johnstown, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in the Mode of Hanging and Operating Churn- Dashers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in which Figure 1, represents a perspective view of a churn with two churn dashers, the box being represented as broken out. Fig. 2, represents a top view of a churn with three dashers.

The nature of my invention relates to the manner of so hanging and operating two, three, or more revolving churn dashers within a churn box and arranged in a longitudinal direction, as that each succeeding dasher in the series shall revolve in a direction contrary to the preceding one and have also its blades inclined in a direction contrary to the preceding one, thus causing an amount of agitation in the cream; which will materially shorten the operation of churning.

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

A, represents the churn box, and B, G, D, represent the dashers.

I11 Fig. 1, the dasher B, has its bearings respectively in the side of the box A, and in the pillar block E, while the bearings of thedasher C, are respectively in the pillar block E, and in a step in the adjust-able set screw 5. The shafts of the dashers B and C, are parallel, and they are connected to each other by means of the pinions a, a, which are secured, one to each shaft, and thus when one of the shafts is turned, the other will turn in a direction contrary to it. The two dashers thus working in relation to each other, and revolving in opposite directions will cause the cream to be agitated with an efficiency which will materially shorten the operation of churning. Nor is this arrangement confined to a fixed number of dashers, as three and more can be used in the same churn according to its size, and each one of the series running in a direction contrary to its next adjacent one. Fig. 2, shows an arrangement of three dashers, and on the same principle any number can be arranged without changing the characteristics of the machine; it is obvious that whatever number may be used, the motions of any two adjoining dashers will be in opposite directions. To accomplish this object, by the simple arrangement of the pinions a, within the churn box, and this I consider the leading feature of my invention, nor do I confine my invention to the application of cogged wheels alone, as pulleys or other mechanical devices may be used on the inside of the churn box, to effect the same object, which is to give two three or more dashers in one churn box motions in opposite directions by gearing arranged on the inside of the box. The object in reversing the inclination of the blades in each adjacent dasher of the series is, to prevent the cream from moving in any one direction, as it would do if the shafts and blades were straight, or if they all inclined in the same direction. If straight the force of the current would be around the shaft, but this is counteracted by breaking the line of the shaft, though still keeping them parallel with each other. If the blades were inclined in one direction only, then the cream would be forced to that end of the box toward which the inclination tends. By breaking the line of shafting and by skewing the blades of the adjacent dashers of the series, I counteract both tendencies of the current to follow the shaft, and the inclination of one of the series, and thus create the greatest possible amount of agitation, and prevent the cream from flowing in bulk in the box. lVhatever current each dasher may make around itself, it is at the same time jetting a horizontal stream into the stream of the next adjacent dasher.

Having thus fully described the nature of my invention, I would state that I do not claim putting two or more dashers in one churn, as this is not new; nor do I claim revolving the dashers in contrary directions by gearing arranged outside or inside of the churn box, but

What I do claim herein as new, and desire to secure by Letters Patent, is

Arranging the shafts of a series of revolving churn dashers longitudinally in the churn box and connecting them by means of cogged wheels or other mechanical equivalents when the latter are arranged inside of the churn box, and rotate each adjacent pair of dashers in contrary directions, as shown, and when the blades of the dashers in each series incline in contrary direc= tions also, substantially in the manner and for the purpose herein described.
