" SIPHON-SKIMMEE. i

Specification of Letters Patent.-

Patented'Nov. 26. 1 907'.

To: all whom it may con-cam:

.Bert known that I, (JURris HARBERT, a citlzenof the United States of America,- residing at Smethport, in the county of McKean and State of Pennsylvania, have invented new and useful improvements 111 Siphon-Skimmers, of which the f llowing is a specification.

My invention relates to a device for removing cream from milk receptacles in such a manner as to draw oil the layer ol' cream without disturbing the underlying bod-y ol milk.

W object of the invention is to provide a simpleand eilective construction of siphon skimmer, whereby the operation of with drawing the cream may be conveniently performed. Another object is to provide a siphon having, means for controlling the flow of the current'of cream.

A still further object is to provide a gage for. indicating the depthto which the siphon shculdbe' introduced into the bottle or container for the complete withdrawal of the layer of cream.

In the accompanying draw1ngs,-F1gure 1 'is a sectional view of a milk bottle showing the application of the invention thereto. Fig. 2 is a sectional view of the siphon skimmer.

Referring to the drawings, 1 designates a milk receptacle, shown in the present instance in the arm of a bottle of ordinary form and standard size to contain, say, a quart of milk; 2 designates a body of milk within the bottle; and 3, the superposed layer of cream which has risen from the, milk.

In carrying my invention into practice I provide means for su porting the skimmer upon the neck of a. ottle, the supporting means shown in the present instance comprising a cap 4 adapted to rest upon and engagethe rim of the bottle neck. This cap is provided with a tubular guide sleeve 5 conforming in diameter to the short leg of the siphon 6. The said short leg 7 of the siphon comprises a tube open at each end and pro vided at its lowerv end with a scale 8 having graduations in inches with designating numerals extending upwardly in regular order from the lower end thereof. This gage may be of any suitable length and is provided to enable the leg 7 to be inserted a required depth in the bottle in an easy and conven within the leg 7 and is similarly provided with a stem 15 carrying at its upper end a knob or finger iece 16. The lower end of the plunger 1 1 1S curved, as shown at 17, so that when drawn up -to its fullest extent it will conform to the arc of curvature of the upper wall of the part 10, to guide the discharging column of cream thereinto.

Suitably attached to the supporting cap 4 is a gage strip 18, preferably consisting of a section of metallic tape bearing an inch scale arranged in a reverse order to the scale upon the leg 7 of the si hon, namely, with the designating numeral; thereon extending downwardly instead of upwardly.

In 0 oration, the device is applied to the bottle in the manner shown in Fig. -1,.the cap being first inserted into position and the gage 18 allowed to depend on one side of the bottle. By reference to this gage 18 the operator may determine from exterior visual observation the extent to which the leg 7 should be inserted in the bottle to bring the lower end thereof down to the bottom of the layer of cream 3. present instance that the numeral12 011 the scale 18 registers with the line of demarkation between the body of milk and layer of cream, thus indicating that the leg 7 should be inserted to the depth of twelve inches. The leg 7 is passed through the guide sleeve 5 in the cap and forced downward until the scale line 12 thereon registers substantially with the upper surface of the cap, the siphon being supported by the frictional engagement between the leg 7 and wall of the sleeve 5. After the parts have been applied, the plunger 14 is drawn upwardly until it occupies the position shown in Fig. 2, thus forming a partial vacuum in the siphon, which causes the cream to flow upward in the leg 7 until communication is established with elbow 10, so that the column of cream will discharge through leg 9 as soon as the stopper 11 is withdrawn therefrom.

It will thus be seen that my invention provides a convenient and simple form of device by which thed'siyer of cream arising from the milk in a bottle may be conven:

A corresponding plunger 14 is arran ed It will be observed .in the iently withdrawn without withdrawing any of the milk, and by which the short leg of the siphon skimmer may be accurately adjusted to draw off the cream.

Having thus described the invention, what is claimed as new, is

1. A siphon skimmer attachment for milk bottles comprising a supporting member for closing the mouth of the bottle, said member being provided with a guide sleeve, a siphon having its intake leg slidably mounted in said sleeve and provided with a scale having designating numerals extending in increasing valuation upwardly from the lower end thereof for coaction with a portion of said supporting member, and an indicating strip carried by said su porting member and projecting downwar' at one side thereof to depend'upon thee; terior of the bottle, said strip being provided with a cooperating scale having its designating numerals extending downwardly thereon.

' 2. A siphon skimmer attachment for milk bottles comprising a supporting member adapted to engage the mouth of the bottle, a siphon havingits intake leg slidably mountedun said supporting member and provided with a gage com rising a set of designating numerals eXten ing upwardly thereon for coaction with said supporting member, and a gage strip carried by the sup orting member and projecting downwar atone side thereof to depend upon the exterior of the .bottle, said gage being provided with a cooperating set of designating numerals extending downwardly thereon.

. 3. A siphon skimmer attachment for milk bottles comprising'a flanged cap adapted to the cap and projecting downward at one side thereof to depend therefrom upon the exterior of the bottle, said strip being provided with a coeperating set of graduations and designating numerals extending downwardly in increasing valuation.

4-. A siphon skimmer attachment for milk bottles comprising a flanged cap having a central guide sleeve, a siphon having a short leg open at both ends and slidably mounted in said sleeve, and a long leg connected at I its upper end with said short leg below the upper end of the latter, the lower portion of the short legof the siphon being provided with'ascale having numerals extending upwardly thereon for-coaction with a portion of the cap, stoppers slidably mounted in the legs of the siphon, and a gage strip connected at its upper end with the cap and depending at one side therefrom to project down upon the'ontside of the bottle, the numerals upon said strip being arranged in reverse order to the numerals of scale on the siphon. I

In testimony whereof, I affix my signature in presence of two witnesses.
