BUTTER MACHINE June 14, l932.

T. C. ROWLAND BUTTER MACHINE Filed May 2l, 1931 2 Sheets-Sheet 2 Patented June 14, 1932 UNTD STATES TULLY C. ROWLAND, F FERRIS, TEXAS BUTTER MACHINE Application filed May 21, 1931.

This invention relates to butter machines and has for an object to provifle a butter machine having oppositely rotating interdigitating dashers adapted to be driven at high I speed so that the butter will come in approximately three minutes more or less, thus great-V ly speeding up production.

A further object of the invention is to provide a butter machine in which the shafts of the dasliers are jointed to permit a quick reinoval of the dashers from the container as .gli

well as quick replacement of the dashers therein.

A further object is to provide a skeleton support or frame for the container having a ring on the bottom plate for properly centering the container.

A further object is to provide novel dashers so constructed as to promote thorough agi- ,i tation of the milk with minimum manual f. may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings forming part of this specification,

Figure 1 is a vertical sectional view through a butter machine constructed in accordance with my invention,

Fig. 2 is a plan view of the butter machine,

Fig. 3 is a detail perspective view of the flashers assembled, anfl Fig. 4 is a detail sectional view showing the i: construction of the joints of the dasher shafts.

Serial No. 539,066.

Referring now to the drawings in which like characters of reference designate similar parts in the various views, the support orl frame of the butter machine is shown to comprise a top plate and a bottom plate 11, said plates being spaced from each other and connected together preferably by four corner legs 12. These parts are preferably formed of metal, and it will be observed, by referring to Fig. 1, that a ring 13 is formed integral with the top face of the bottom plate 11.

A container 14, preferably formed of metal, is provided with a base flange 15 which seats within the ring 13. The top of the container is closed by a cover 16 which preferably is formed of wood and is provided with a groove 17 to receive the top edge of the container. A socket 18 is formed integral with the bottom of the container at the center thereof.

By now referring to Fig. 3, it will be seen that a pair of

dashers

19 and 20 are provided. The flasher 19 is preferably rectangular in marginal outline and is preferably formed of sheet metal stamped to produce a substantially rectangular frame-21 and substantially rectangular vanes 22 which extend from the sides of the frame toward the center of the frame, the vanes being arranged in pairs, and the vanes of each pair being in alinement with each other and terminating short of each other at the free ends so as to permit a space existing therebetween to receive the mating dasher, which will presently be described. rllhe vanes 22 are provided with longitudinal openings 23 which aresubstantiallj7 rectangular in outline.

The flasher is also preferably formed of sheet metal and is shaped to provide an axial shaft 24 of suiiicient width to be rotatably received between the ends of the vanes 22 of the dasher 19. Vanes 25 project laterally from the shaft 24, the vanes being arranged to extend in pairs, as shown, the vanes on each side of the shaft being disposed in alinement with the similar vanes on the opposite sides of the shaft andbeing of suliicient width to be rotatably received in the spaces between the vanes 22 of the dasher 19. The

vanes 25 are provided with longitudinal '7- dashers are rotated in opposite directions relatively to each other at high speed by mechanisni which will be presently described, and, during such rotation, the interdigitating vanes, equipped with corresponding escape.

openings

23 and 26, produce an extremely thorough agitation of the milk so as to bring the butter in from one to three minutes, in actnal practice, from either sweet or sour mil r.

By referring now to Figs. 1 and 3, it will be seen that the dasher 19 is provided at the top and bottom with

fianges

27 and 28, and the bottom flange is provided with an orifice 29, as best shown in Fig. 1, to receive a gudgeon 30 carried by the shaft 24 of the dasher 20. The gudgeon projects through said orifice and is journaled in the above mentioned socket 18 formed at the center of the bottom of the container 14. This gudgeon also, it will be observed, forms a bearing upon `which the dasher 19 is rotatably'mounted at the bottom.

The flange 2T at the top of the dasher 19 is provided with a centrally disposed upright tube 31 which opens through the fiange and which, as will hereinafter appear, forms one section of a tubular shaft for rotating the dasher.

rlhe top edge of the tube is provided with a notch to receive a ratchet tooth 33 formed integralwith the reduced lower end 34 of a sleeve 35, as shown in Fig. 4. The sleeve is slidably fitted on the lower end of a tube 36 by means of a pin 37 projecting from the tube into a longitudinal bayonet slot 38 formed in the sleeve. The lower end of the slot is offset from the axis of the slot to provide a sea-t 39 into which the pin may be lodged when the sleeve is slid upwardly on the tube 36 to hold the sleeve raised and disengage the tooth 33 from the notch 32.

The above described tube 31, sleeve 35, and tube 36 form a tubular shaft which may be said to be provided with a separable joint provided by the ratchet tooth 33 and notch 32 to permit disassembly of the dasher from the shaft when the sliding sleeve is moved upwardly.

The ratchet tooth permits rotation of both

tubes

31 and 36 of the tubular shaft as a unit in one direction. It also permits the lower tube 31 to stand stationary when the direction of rotation of the crank handle is reversed, for then the ratchettooth 33 rides' out of its notch and the sleeve rides up on dasher 20, by slowly rotating same, to gather the butter, after the butter is made.

A shaft 40 for the dasher 20 is rotatably received in the tubular shaft of the dasher 19. The shaft 40 is split transversely within the enclosure of the sleeve to provide a step joint 41. The lower section 42 of the shaft passes downwardly beyond the tubular shaft and is grooved, as shown at 43, to embrace the upper edge of the axial shaft 24 of the dasherJ 20, as best shown in Figs. 1 and 3..v

rlhe shafts of both dashers are rotated oppositely to each other by mechanism which will now be described. The shaft 40 is equipped at the top with a bevel pinion 44, and the tubular shaft is equipped with a bevel pinion 45. A bevel gear 46 is disposed to mesh with both pinions and is fixedV to a shaft 47 which carries a flywheel 48 and also a gear pinion 49. The ends of the shafts are journaled in

suitable bearings

50 and 51 rising from the top plate 10 of the frame. The bearing 51 is angular in outline, as best shown in Fig. 2, to also provide an additional bearing 52 for a shaft 53 which carries at one end a gear 54 disposed in mesh with the pinion 49 and which is equipped at the opposite end with a crank handle 55. A suitable housing 56 is disposed to enclose the gear mechanism and is equipped with a bearing- 57 which, as best shown in Fig.. 1, rotatably receives the upper end of the shaft 40. Preferably, the gear ratios are such as to rotate the dasher shafts oppositely at a speed of about seven times more or less the speed of the crank shaft 53.

To disassemble the parts for cleansing, it is simply necessary to slide the sleeve 35 of the tubularV shaft upwardly and give it a lateral twist to seat the pin 37 in the odset end 39 of the slot 38. In this position of the sleeve, the tooth 33 is disengaged from the notch 32, while, at the same time, the step joint 41 of the shaft 40 is exposed below the sleeve. Consequently. the joints of both shafts are disconnected to permit of the container 14 being tilted up and removed bodily from the frame. Access to the flashers, of' course, is then .afforded by simply removing the cover 16, whereupon'both dashers may be removed as a unit from the containerand thereafter separated for thorough washing. To assemble the parts, the above described cycle of operations is reversed.

` From the above description it is thought that the construction and operation of my invention will be clearly understood without further explanation. f

Having thus described the invention, I claim:

1. A butter machine comprising a frame, a container carried by the frame, dashers in the container having interdigitating vanes, a hollow shaft for rotatingone of the dashers,

a jointed shaft within the hollow shaft for rotating the other dasher, means carried by the frame for rotating both of said dashers oppositely to each other, said hollow shaft being formed of tubular sections, and a coupling sleeve having a ratchet tooth and notch connection with one Iof the sections and being slidably mounted on the other section by a pin and slot connection whereby said sections may be rotated as a unit in one direction or one of the sections may be uncoupled from the driving means by the ratchet tooth riding out of the notch and the sleeve riding up on the pin when the direction of rotation is reversed to let the dasher carried by the hollow shaft idle.

2. A butter machine comprising a frame, a container carried by the frame, dashers in the container having interdigitating vanes, a hollow shaft for rotating one of the dashers, a step jointed shaft housed within the hollow shaft for rotating the other dasher, means carried by the frame for rotating said dashers oppositely to each other, said hollow shaft being formed of tubular sections, and a sliding coupling sleeve on one of the sections having` a pin and bayonet joint connection therewith and having a ratchet tooth connection with the other section whereby said sections may be rotated as a unit in one direction or one of the sections may be maintained stationary when the direction of rotation is reversed, said sleeve housing the joint of the step jointed shaft, manual upward movement- -of said sleeve engaging the pin in the lateral portion of the bayonet joint and disengaging the ratchet tooth joint of the hollow shaft and exposing the step joint of the other shaft to uncouple both shafts from the driving means and permit removal of the container and dashers laterally from the frame.

3. A butter machine comprising a frame, a container, concentrically disposed dashers in the container having interdigitating vanes, a

shaft for one of the dashers having a step joint, a tubular shaft for the other dasher formed of aligned upper and lower sections, the lower section having a notch in the upper edge, means carried by the frame for rotating both shafts in opposite directions, and a sleeve mounted on the upper sections of the tubular shaft and slidable longitudinally thereof, said sleeve having a ratchet tooth on the lower edge engaged in said notch to couple the sections of the tubular shaft together for rotation as a unit in one direction and uncouple said sections when the direction is reversed, said sleeve being provided with a longitudinal bayonet slot having a lateral seat, the upper section of the tubular shaft being provided with a pin engaged in said slot, said sleeve being manually movable upward to disengage the ratchet tooth from the notch and uncouple the sections of the tubular shaft, said pin lodging in said seat at the upper limit of movement of the sleeve and holding said sleeve raised to eX- pose the joint of the step jointed shaft below the sleeve to permit the container with the dashers therein being removed as a unit laterally from the frame.
