HERMAN WAAGBO, OF NORTHPORT, MICHIGAN";

Application filed February '23, 1926.

My device relates .pri-maricREAM-r-ns'rnw DEV-ICE.

1y to apparatus used by creamerles and the like in the testing of cream and other purposes but it may also be used :for any purpose in which it is necessary to obtain a small, exact amount of any liquid. Its purpose is to make .a device that shall make it possible to quickly 'draw in and discharge a close approximation to the exact amount and then quickly adjust it to practically absolute exactness, one operation.

1 obtain these purposes substantially at .by the means shown in the accompanying drawings in which Figure 1 is .a

longitudinal section of my device through the center of the piston rod on the line '2-2 of Figure '2. Figure 2 is a similar section taken on the line 2-2 of Figure 1. Figure 1 shows the parts 111 .po-

sition in which the cream into the device.

is being drawn Figure 2 shows the parts in position in which the cream has been completely expelled from the de vice.

Referring more particularly to the draw- .ings, 1 is the main body of my the top and closed by a cap 2. It

is open at is narrowed at the bottom device which to form a very small second cylinder 3. A piston 4 provided with a hollow rod 5 moves air tight in the body 1 and a second ed inside the able in the small cylinder 3, low rod. I have found by the length of the opening in 5 is such that the cylinder is piston 6 is mounthollow rod .5 and is freely slidand in the holexperience that the hollow rod sufliciently close without the use of any packing, but as stated above, packing may be used out departing from my plate 7 provided attached to the upper end of invention. wlth a thumb opening 8 is if desired with- A flat the rod 5 and a thumb piece 9 to the upper end of'the rod 6.

The opening 8 is placed at a distance from the top of the rod 5 substantially equal to the length of the opening in inder 3.

For the purpose the small cylof holding the device firmly in operation, rings 10 are attached, but

firmly by the rings device is immersed other proper holding device may be emm my invention.

device is as follows 10 the in the is raised by the 9 until it comes opposite the small quantity of r 3. When this of the piston 6 not quite, supply the desired amount.

Serial No. 90,024.

tended through the opening 8 and the two pistons are withdrawn together until the entire body 1 is fullof cream. It is then placed over the containing dish and the two pistons are pushed down together until the large piston reaches the bottom of its stroke which is so adjusted that it will nearly, but The thumb is then released from the openin 8 and the small piston is pushed down ischarging the cream from the small cylinder 3 drop by drop until the desired amount is obtained. An adjusting ring 12 is mounted so as to slide freely and be readily removed from the rod 5 for the purposeof regulating the amount of cream that may be drawn into the main body. The adjustment is made by using longer or shorter rings .as may be desired.

I claim as my invention and desire to secure by Letters Patent:
