COLUMBUS MILLER, JOHN WV. BLUE, AND CHARLES S. MILLER, OF KEYSTONE,
SPECIFICATION forming part of Letters Patent No. 429,356, dated June 3, 1890.
Application filed March 14, 1890- Serial No. 343,936. (No model.) I I cross-section thereof on about line 2 2 of Fig.v
r5 1. Fig. 3 is a detail perspective view of the dasher and shaft and its supporting and operating devices, and Fig. at shows the single dasher.
The churn-bod y has a suitable lid CL, and is provided in its ends with bearings B and C. The dasher-shaft I) has the dasher-section H secured to its central portion, and is formed near its ends at h to provide journals for the end tubes or portions 1 of the dasher-section I. This section I is made in the form of a frame journaled at h on the shaft D. The section H operates within the section I, with its blades h operating between the inwardly-projecting blades 1' of section I.
It will be seen from the foregoing that the dasher-sections H I may be turned in opposite directions, the tube or sleeve-like portions t turning freely on the parts h of the 3 5 shaft D. At one end the shaft D is formed to receive the point of screw E, which is threaded in bearing B, while at its opposite end the shaft has a square or angular stem or tenon D. This stem D is received in an angular socket fin the inner end of a subshaft F, which extends at its outer end beyond the side of the casing, and is provided at such end with a pulley F. A shaft G, in the form of a sleeve, journals in bearin g C and encircles the shaft F, so as to turn freely thereon and to permit the free independent turning of such section F. flared or enlarged atits inner end, and is adapted at such end to engage the dashersection I, being preferably provided with ap- This shaft G is proximately diametrically-opposite notches g g, which receive the edge of section-I, so such section will be turned by the turning of shaft G. At its outer end the shaft G is provided with a gear-wheel G.
In operation the wheels F G and their attaehed shafts and operated parts are turned in opposite directions, preferably by means of pulley-wheel F and gear-wheels G a belt F or sprocket-chain connecting wheels F F and the wheels G G being arranged to mesh, such wheels F G being fixed so they will turn together, preferably by securing them on a common shaft, as shown.
By the described construction it will be seen that the turning of shafts F and G will operate to turn the dasher-shafts in opposite directions, such sections being so constructed as to break up every particle of the milk and cream when so operated.
While we much prefer the double dasher H I, as shown, it will be understood that where a single dasher is desired the single dasher shown in Fig. 4 may be used.
Manifestly, where the shafts D F connect, it would involve no departure from the invention to reverse the socket-and-stern formationthat is to say, to make the socket in section D and the stem or tenon on the section F, as such construction would be in a measure the equivalent of that shown.
It will be understood that the pulley F and gear G are connected with the d.tSl1G1- sections, so that the said dasher-sections may be regarded as provided with such wheels.
The eh urn-body is provided below its ch u ming-chamber with a water-receiving chamber N, formed between the bottom plate of the churn-body and the false bottom it, such chamber extending up along the sides of and 0 from end to end of the body, and having at one side an opening N, through which the water may be supplied.
Having thus described our invention, what we claim as new is V 5 1. In a churn, the combination of the inner dasher-section H, the shaft D, secured to and supporting section H and extended at its ends beyond said section, forming journal portions for the outer dasher I, the dashersection I, fitted over the section H and having at its ends portions '5, fitting and turning on the journals at the ends of shaft D, Whereby such shaft supports the inner dasher-section and forms bearings for both ends of the outer dasher-section, theshafts F and G, engaging said shaft and dasher-section I. and operating means whereby such shafts may be turned in opposite directions, substantially as and for the purposes set fo th.
2. In a churn, the combination of the dash ersection II, having shaft D, provided with tenou D, the dasher-section I, fitted over the section II and journaled on shaft D, the shaft F, having at its inner end a socket receiving the tenon D, the shaft G, fitted over the shaft F and having at its inner end notches g to receive the end of dasher I, means for operating such shafts F and G, and means for supporting the other end of the dasher, all substantially as and for the purposes set forth.
3. In a churn, the combination of the shaft D, having at its ends bearings h, the dashersection II, secured to such shaft D, the dashersection I, fitted over the section II and having at its ends tube or sleeve-like portions 1',
journaled on bearings h, the shaft F, connected at its inner end with the shaft D, the shaft G, having its inner end notched to engage the dasher-section I, and the drive-gearing, all substantially as and for the purposes set forth.
4. In a churn, the combination, substantially as hereinbefore described, of the shaft D, having at its ends bearings h h, the dasher-section II, secured to such shaft D between bearings h, the dasher-section I, having at its ends tube or sleeve-like bearings journaled on bearings h, the screw by which to support one endof shaft D, the shaft F. having at its inner end a non-circular socket receiving a non-circular tenon on the shaft D, the shaft G, encircling shaft F and having at its inner end notches to receive the edge of dasher-section I, and mechanism by which to turn such shafts F and G in opposite direction, substantially as described.
