SEPABA'I'OR FOB MILK AND CREAM. I

Application med June 11, 1925. Serial m. 87,788.

This invention relates to an improved device which has been devised for separating cream. from milk, and it has more particular reference to a comparatively small domestic contrivance such as may be inserted into an ordinary milk bottle to provlde a partition between the milk and cream and to permit the cream to be poured out without allowin' the milk to mix therewith.

Broa l ,the device embodies a se a'rator which is intended to be located in t e milk bottle to function as the aforesaid partition,

this separator being expansible and contractible so that it may be contracted to facilitate insertion and will then be expanded to provide a fluid tight joint with the neck 2f the bottle when functioning as said parti- The invention also embodies numerous. other structural details resulting in outstanding features and advantages and these will be more particularly pointed out in the fol.-

I lowingldescription and appended claims.

Figure 2 is a view taken substantially at right angles to Figure 1 with the device removed from the bottle.

Figure 5 is a bottom plan view of the separator.

Fi re 6 is a detail section taken approximate; y on the plane of the line. 6--6 of Figure In carrying out the invention I employ an improved separator which is designated generally by the reference character 1. This separator is of disk-like form, and is made up of a central section 2, and a pair of duplie construction of .the

cate end sections 3. These sections are. ref erably in the form of segmental metal p ates rying meanspreferably comprises a pair of spaced downwardly diverging rods 6 which- .strips 5 (see Figure 5) The two end-sections 3 are hin edl connected to the central section and adapted to fold into the contracted-state shown in Figure 6. They 00 are in this relation'during the insertion and removal of the device from the bottle.

Appropriate carrying means is provided forassoclation with the separator. The car- 4 extend u and are connected witha peculiarly shaped plate. At their lower ends, these rods 6 are connected to a head 8, and this is in turn connected at 9 to the center of the intermediate section 2 of the separator. Re ferrlng again to the plate 7 it will be seen thatit is fashioned to provide an attaching. neck 10 fastened to an a propriate handle 11. This plate also provids a mounting for 7 an oscillator se ental gear 12,-which is provided wit a nger grip 13 for operating said gear (see Fi res 2 and 3). On the front of the plate is an outwardly extending ear through which the stem 14 of a tilting member 14 passes. A coiled spring 15 sur'- rounds this stem, ars against the ear at one end and against a head 16 at its opposite end whlch is on the upper end of the tilting member. This tilting member extends down- .wardly and is pivotally connected at 17 to the central section of the separator. This tor maybe swung about the pivot 9 so as to swi it against the rod as indicated in dotted llnes in Figure 1. In this connection it will be noted that a pair of intermeshing pinions 18 are journaled for rotation upon the upper portions of the rods, and are arranged so that the teeth of the aforesaid segmental gears 12 cooperate therewith to simultaneously rotate saidpinions in opposite directions. v

At this time I would direct attention to the fact that a pair of, arms 19 are secured to and rotate with the pinions' 18. These arms extend downwardly and have laterall directed lower ends 20 extending ,throug staples'21 carried by the end sections 3 oi the aforesaid separator. {The arms, if demaybe made up 'of two: parts, the upper part of thin plate like form and the lower end part in the form of a wire rod.

It is yet to be pointed out that a substantially U-shaped bracket 22 is provided (see Figure 1), with a sleeve 23 slidable upon the aforesaid tilting member 14. A set screw 24 is carried by the sleeve for holding the bracket in various adjusted positions. If desired, a strap 26 is provided on the member 14 for limiting the downward sliding movement of the bracket.

The operation of the device is as follows: When it is desired to separate the cream in a bottle from the milk, it is necessary to insert the device into the bottle asjshown in Figure 1, at which time the separator 1 .is utilized as a partition, marking the line of division between the cream at the top and the milk below it. Owing to the fluid tight contact of the periphery of the separator with the bottle, the milk may be maintained in the bottle while the cream is poured out 'into a suitable receptacle. In order to insert the device, the handle 11 is grasped, and the thumb is placed against the spring pressed plunger rod 14, or rather. against the finger piece 16 of the "prop thereof. Now

a downward pressure is exerted upon this rod to swing the entire separator upon the pivot 9 to the approximate right angular position shown in Figure 1. One finger of the same hand may be passed through the finger loop 13,- and when the separator is in the right angular position stated, the seg- -mental gear 12 may be operated through the medium of the finger piece, which serves 4 to rotate the pinions and to collapse or fold zontal plane shown, and the device is lifted.

division ,plate between the cream and the the outer sections 3 of the separator into the substantial overlapping relation .shown in Figure 6. The device may now be easily inserted down into and through the milk without materially disturbing the same.

Now the finger piece 16 is released and the segmental gear is moved in the opposite direction to return the separator to the horiup into the bottle untilthe peripheral edges of the separator come into contact with the inner surface of the neck of the bottle. A partition is now provided which serves as a milk, thus allowing the cream to be poured oft without disturbing the milk. In order to maintain the device in the position shown in Figure 1, the bracket 22 1S hooked over the head of the neck of the bottle and the .set screw 24 is tightened. In removing the the spirit of the invention, and the scope of the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. A separator for milk and cream, comprisirfg a handle, a separator having a central section and a pair of end sections hinged thereon, said central section having a pivotal connection with the handle, a pair of rods rotatable in the'handle, each rod havi one end pivotally connected to one of sai end sections of the separator, means for rotating said pair of rods, and means for moving the central section on its its pivot.

2. A separator for milk and cream, comprising a handle member, a separator having relatively movable end sections ivotally mounted on one end of said han e members, a member slidable relative to the handle, having a pivotal connection with said separator for producing a pivotal movement thereof on the handles, said member having means thereon for engaging the rereptacle for the milk and cream, means rotatably mounted on said handle member and connected with the foldableend portion of the separator for operating said end portion in the rotation thereof, and manually operable means mounted on the handle member for oscillating movement and connected with the rotatable means adapted to operate said means in the manual oscillatiomof the,

with each foldable end section and rotatably mounted in spacedparallel relation in said handle member, intermeshing pinions mounted on. said rod members, a gear segment oscillatable on said handle member and intermeshed with one of said pinions adapted to-rotate said rod in the-oscillation of said gear segment, and means for manually -operating said gear segment.

In testimony whereof I aflix signature.
