JOSlAH RIDDICK YARBROUGH, GF FLORENCE, ALABAMA.
COMBINED CHURN AND FEEZER.
SPECIFICATION forming part of Letters Patent No. 763,139, dated June 21, 1904.
Application filed June 30, 1903. Serial No. 163,779. (No model.)
Tamil, iti/1,0111, it may concern.-
Be it known that I, JosIAH RIDDICK YAR- nnoUeu, a citizen of the United States, residing at Florence, in the county of Lauderdale and State of Alabama, have invented a new and useful Improvement in a Combined Churn and Freezer, of which the. following is a specification.
My invention relates to a combined churn and freezer, and has for its objects to produce a device of this character of comparatively simple construction which will be efficient in operation, one in which the inner cream-receiving vessel may be readily cleaned, one in which the cream at the bottom of the Vessel will be brought into contact with the cooling medium, and one in which the upper member of the dashcr will have an automatically-reversible rotary motion during the reciprocation of the dasher.
'lo these ends the-invention comprises the novel details of construction and combination of parts more fully hereinafter described.
in the accompanying drawings, Figure 1 is a central vertical longitudinal section of adevice constructed in accordance with my invention. Fig. 2 is a detail perspective view of the removable bottom of the cream-receptacle, illustrating the manner of locking the same in place. Fig. 3 is a similar view of the upper rotary dasher member.
Referring to the (.lrawings, 1 indicates the outer vessel, and Q the inner vessel, of my improved device. .l`hese vessels are composed of tin or other suitable or desired material and are preferably of cylindrical form, the inner vessel being of suf-h a size relative to the outer vessel that when the parts are assembled for operation an intervening space 3 betweenthe vessels and surrounding the inner one will be provided for the reception of ice or other suitable cooling medium. The inner vessel is provided with a cover 4, which has a depending peripheral iiange for engagement over the open end of the vessel and a central opening 5 for the reception of the dasher-rod or shaft 6. '.lhe cover has formed upon it adjacent to and surrounding its central opening 5 a chamber or compartment 7,L which receives a disk 8, of leather or other suitable packing material, which snugly embraces the shaft 6.
The inner vessel 2 has a primary bottomi), which in practice rests flatly upon the bottom of the outer vessel, and a secondary removable bottom preferably of conical form and disposed with its base resting upon the upper face of the primary bottom, whereby a compartment 11 is formed, which in practice is filled with ice or other cooling medium such as is employed in the outer vessel. The secondary bottom has upon its base a peripheral flange 12, provided with a plurality of radial recesses 13, which when the bottom is inserted to position register withradial fingers 14:, attached to the inner side walls of vessel 2 and spaced from its primary bottom suiiicicntly for the fiange 12 to pass beneath them for maintaining the bottom 10 in pla'ce, as will be readily understood, it being understood, of course, that other means may be employed `for this purpose.
15 is a clamping member, preferablyv composed of wire, bent to form a pair of parallel.- spaced arms, which in practice extend transversely across the open end of vessel 1 and have at one end upturned fingers 16, which engage through suitable perforations in the Vside wall of the vessel beneath its peripheral bead or flange, the member being bent at its other end to form a spring-finger 17, which extends slightly downward and inward forengagement with the said bead to lock the member in position. 1n practice when the parts are assembled the member 15 bears upon the cover of the inner vessel for maintaining said cover securely in position and the vessel in proper position within the outer vessel, the member being upwardly arched at its center for engagement over the upwardlyarched cover 4. 1t is also to be noted in this connection that in practice the parallel arms of the member will lie one upon either side of the shaft (S when the latter is in position, thus obviating any conflict of thc parts in assemblage.
The shaft 6' is provided at its upper end with a handpiece 18, which in practice is grasped by the operator, and at its lower end with a threaded portion 19, which engages a central internally-tlneaded opening formed at the apex of a coneeshaped hollow dasher member 20, the walls ot' which are provided with perforations 21, which permit the passage of the cream during the reciprccation of the dasher, the latter being of a size and contour to seat or nest upon the conical bottom of the vessel 2 during the operation of the parts. The fixed dasher is provided with a peripheral liange 22, 4which in practice contacts at its outer edge with the .inner wall ot' the cream vessel, whereby the shaft is properly guided in its reciprocatory movement and the wall of the vessel is freed from the adherence ot cream thereto.
23 is a rotary dasher member mounted upon the shaft (i directly above the dasher 2O and maintained thereon by a movable adjustable collar 24, adapted to be held in fixed relation to the shaft by a set-screw or the like. The rotary dasher 23 is composed, preferably, of sheet metal and is oi substantially propeller form, having four radiating blades which are suitably inclined transversely between the vertical and horizontal to insure their passage through the cream during the reciprocation of the shaft, imparting to the dasher a rotary motion, which of course reverses at the beginning of each stroke oi' the shaft G-that is, when the shaft begins its upward movement the dasher will rotate in one direction and when the shaft begins its downward movement the rotation of the dasher will be reversed and it will rotate in the opposite direction. Thus it will be seen that the cream will be thoroughly agitated and stirred by the said dasher.
ln practice the removable bottom l() is first filled with ice, the vessel 2 inverted, and the bottom secured in position in the manner above explainedI by giving it a partial turn for engagement beneath the tingers 1 4. 'l he vessel 2 is then lilled with cream or the like and properly closed and positioned in the vessel 2 and the space 3 filled with ice. Reciprocation of the shaft 6 ycauses the dashers 20 23 to thoroughly agitate the cream, as will be readily understood, whereby' the contained air will be freed and the cream rapidly frozen. lt will be noted in this connection that the cream in the vessel 2 is subiccted to the action of the cooling medium at the bottom of the vessel as well as the sides, whereby the treezing of the mass will be equalized. lt is also to be noted that when the vessel 2 is to be cleaned the bottom l0 may be readily removed, thus greatly facilitating the cleansing operation. When the device is to be cniployed for churning, the manner of assemblage and the operation or' the parts are the same as that above described, except that it is preferable to employ water as the cooling medium in the outer vessel.
From the foregoing it will be seen that l produce a device of comparatively simple construction, vone which will be elhcient in operation, and one which in practice will admirably perform 'its functions. ln attaining these ends l do not limit myself to the precise details herein show-n and described inasmuch as minor changes maybe made therein without departing from the spirit or scope of the invention.
Having thus described my invention, what l claim, and desire to secure by Letters Patent, isp ln a device of the class described, the combination with an outer vessel, of an inner vessel situated therein and having a primary bottom and an inner secondary hollow bottom serving in conjunction with the primary bottom to form a chamber, said secondary bottom being wholly removable from the vessel andhaving its normally lower end entirely open, means lor securing' the open end of the secondary bottom removably tothe primary bottom whereby the latter lforms a closure therefor, and a dasher disposed for operation within the inner vessel.
ln testimony that I claim the foregoing as my own l have hereto afiixed my signature in the presence oi two witnesses.
