DASHER FOR CHURNS.

SPECIFICATION forming part of Application filed. August Z1, 190.3- Serial No. 170,249.

Letters VPatent No. 742,712, dated October 27, 1903.

(No model.)

Tc a/ZZ 'whom t may concern:

Be it known that I, JAMES WILLARD Mon- RIs, a citizen of the United States, residing in the borough of Manhattan, city, county, anfl State of New York, have invented a certain new anfl useful Improvement in Dashers for Churns, of which the following is a description.

The present invention relates to improvements in dashers for churns of the type which forms the subject-matter of an application filed by me of even date herewith, Serial No. 170,248. In the application referred to a churn in which a dasher formed with live sharp-eflged wings and as a modifie. tion a flasher with four wings and as another modiication one with two wings are shown. The present invention relates to improvements on the latter modification.

In the flasher which forms the subj ect-matter in the above-referred-to application a hollow neck is formedintegr. l with the dasher and a central cylindrical opening forms the air-chamber, which communicates with the exterior faces of the dasher through horizontal openings. The flasher is supported from the hollow neck.

The object of the present invention is to avoid the necessity of forming the integral hollow neck and to simplify the support for the rotating shaft.

Another object of the invention is to improve the eiciency of the dasher and to simplify its construction and reduce the cost of manufacture thereof.

In order to`better understand the nature of the invention, attention is directed to the accompanyin g drawings, in which- Figure 1 is a perspective view of the dasher. Fig. 2 is a sectional view thereof on the line 2 2 of Fig. 1. Fig. 3 is a top view of a modified form of flasher, and Fig. 4 a sectional view thereof on the line 4 4 in Fig. 3.

In all the several views like parts aredesignated by the same numerals of reference.

The improved flasher is formed of a single piece of wood or other material 1, with a iiat top 2 and bottom 3and sharp cutting eflges 4 4. The dasher is in the form of two wings and with each sifle formed of a double conshown in the vox and concave curve, as is drawings; Each wing is formed with a convex surface 5 and a concave surface 6 and is adapted to rotate in the direction of saifl concave surface.

The flasher is suspended from the shaft 7 by means of the metallic fitting 8, which consists of a socket 9 and a fiange 10, which is secured to the top 2 of the dasher by means of screws or other fastenings 11. A tapered pin'12, driven through suitable holes, serves to removably connect the socket 9 with the lower extremity of the shaft 7. y

In lieu of the single air-passage in connection with each cutting edge, as described and illustrated in my application Serial No. 17 0,248, I employ a plurality of openings 13, live being shown for the purpose of illustration, but the number may be augmented or reduced without departing from the spirit of the invention. These passages extend entirely through the block, which construction decreases the cost of manufacture and somewhatincreases the efficiency of the dasher. Vertical passages 14 serve to connect the transverse passages with the external air. These passages 14 may extend entirely through the body of the dasher, as is illus- 'trated, although they may extend no farther than the lower transverse passage.

Instead of a flasher formed with curved surfaces, as illustrated in Figs. 1 and 2, one with plane surfaces, as illustrated in Figs. 3 and 4, may be used.

1. A churn-dasher having a body anfl a shaft-fitting, said body having oppositel T-arranged cutting edges, anfl air-passages adjacent to such edges, and vertical air-passages connecting with the horizontal passages on Veach side of the shaft-fitting, substantially as set forth.

2. A churn-dasher having a body and a shaft-fitting, said body having oppositely-arranged cutting edges, and a plurality of airpassages adjacent to such edges, and vertical air-passages connec `ng with the horizontal passages on each side of the shaft-fitting, substantially as set forth.

3. VA churn-dasher having a body and a shaft-fitting, the said body having oppositelyarranged cutting edges,and air-passages adroo A through the body the forni of reversed curves, so that two wings are formed, each having a convex and a concave side, and air-passages adjacent to such edges, and passing entirely through the body, each passage extending through both wings, substantially as set forth.

6. A churn-dasher having a body with oppositely-arran ged cutting' edges, and sides in the forin of reversed curves, so that two Wings are formed, each havin a convex and a concave side, and a plurality of air-passages ad* jacent to such sides, and passing entirely through the body, eac-h passage extending through both wings, substantially as set forth.

7. A churn-dasher having a body with oppositely-arranged cutting edges, and sides in the forni of reversed curves, so that two wings are formed, each having' a convex and a concave side, andan air-passage adjacent to such edges,and passing entirely through the body, each passage extending' through both Wings and connecting the convex faces, substantially as set forth.

8. A churn-dasher having' a body with oppositely-arranged cutting edges, and sides in the forni of reversed curves, so that two wings areforincd, each having a convex and a concave side, and a plurality of air-passages adand passing entirely cach passa-ge extending jacent to such edges through the body,

through both wings and connecting the con: vex faces, substantially as set forth.

9. A churn-dasher having a body with oppositely-arranged cutting` edges, and sides in the forni of reversed curves, so that two wings are formed, each having a convex and a concave side, and an air-passage adjacent to such edges, and passing entirely through the body, and vertical air-passages connecting the said through-passage, substantially as set forth.

l0. A churn-dasher having a body with oppositely-arranged cutting edges, and sides in the form of reversed curves, so that two wings are formed, each having a convex and a concave side, and a plurality of air-passages adjacent to such edges, and passing entirely through the body, and vertical air-passages connecting the said through-passages, subsiantially as set forth.

ll. A churn-flasher having a body with oppositely-arran ged cutting edges, and sides in the form of reversed curves, so that two wings are formed, each having a convex and a concave side, and an airpassage adjacent to such edges, and passing entirely through the body, and connecting the convex faces, and vertical air-passages connecting the said through-passage, substantially as set forth.

l2. A churn-dasher having a body with oppositely-arranged cutting edges, and sides in the forni of reversedv curves, so that two win gs are formed, each havinga convex and a concave side, and a plurality of air-passages adjacent to such edges, and passing entirely through the body, and connecting the convex faces, and vertical air-passages connecting the said through-passages, substantially as set forth.

This specification signed and witnessed this 19th day of August, 1903.
